Abstract
The invention discloses a novel centring device for engine simulation experiment, which belongs to the field of detection fixtures for automobile parts. The novel centring device comprises a circular fixing plate, a steel tube, a detection needle and a slide sleeve, wherein a thread guide sleeve is fixed at the middle of the circular fixing plate, an external thread is engraved at the left end of the steel tube, a detection needle fixing rod is fixed at the right end of the steel tube along a radial direction, and the detection needle fixing rod is of a cuboid structure; the slide sleeve is of a rectangular-ambulatory-plane structure and in slide fit connection with the detection needle fixing rod; the detection needle is of a Z-shaped structure, and the tail portion of the detection needle is vertically and fixedly connected with the slide sleeve; the external thread at the left end of the steel tube is matched with the internal thread of the thread guide sleeve. The detection radius of the novel centring device disclosed by the invention is capable of being continuously adjusted according to the side of the flywheel of the detected engine; the novel centring device is reasonable in structural design, low in production cost and good in adaptability; experiment preparation time is reduced, and detection efficiency is increased.
Description
Technical field
The detection frock field that the invention belongs to auto parts and components, more particularly, relates to a kind of centralising device of new work engine simulated experiment.
Background technology
Along with the development of auto industry, the research and development of new work engine type and new technology also gets the attention and payes attention to.For new architecture or new technology are verified, most engine producer has introduced dynamometer machine and supporting control device, threst stand is carried out to the output power of various simulated operations test engine.In the time that engine is manually connected with dynamometer machine, the bad accurate judgement of the right alignment of both tie point positions, easily has deviation, thereby causes the fierce vibrations of body, and equipment is caused to damage.Traditional detection means is carried out sweeping by support and the pointer of regular length to the periphery of engine flywheel, need to determine in advance the size of engine flywheel, select as required again the detection pointer of radii fixus, cannot detect according to actual needs flexibly the adjustment of pointer self.
Summary of the invention
the problem that 1, will solve
For the above-mentioned problems in the prior art, the invention provides a kind of centralising device of new work engine simulated experiment, it effectively detects for the engine of different model size by the adjustable detection of detection radius, and easy to operate, dirigibility good.
2, technical scheme
In order to address the above problem, the technical solution adopted in the present invention is as follows:
A kind of centralising device of new work engine simulated experiment, comprise circular fixed head, also comprise steel pipe and detect pin, sliding sleeve, the middle part of described circular fixed head is fixed with threaded guide sleeve, the left end of described steel pipe is carved with external thread, its right-hand member is radially fixed with and detects pin fixed bar, and described detection pin fixed bar is rectangular three-dimensional-structure; Described sliding sleeve is " returning " font structure, itself and the sliding connection of detection pin fixed bar; Described detection pin is " second " font structure, and its afterbody is fixedly connected with sliding sleeve is vertical; The external thread of described steel pipe left end and the internal thread of threaded guide sleeve match.
Further, on described sliding sleeve one sidewall, have threaded hole, in described threaded hole, trip bolt is installed.
Further, on described circular fixed head, have 4 through holes; Detect pin and adopt No. 45 steels to do, its diameter is 4mm.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
The present invention adopts the fixed head and the steel pipe that are mutually threaded, is easy to install, dismantles and changes; Detecting the detection radius of pin can carry out continuous adjusting according to the size of detected engine flywheel, needn't carry out determining of size according to engine model in advance, has effectively increased the sensing range that detects pin, has realized the versatility of pick-up unit; Its reasonable in design, cost of manufacture is low, adaptability good, has shortened the Preparatory work of experiment time, has improved detection efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is detection pin syndeton schematic diagram of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention is further described.
As shown in Figure 1 and Figure 2, a kind of centralising device of new work engine simulated experiment, comprise circular fixed head 1, also comprise steel pipe 3 and detect pin 5, sliding sleeve 6, the middle part of circular fixed head 1 is fixed with threaded guide sleeve 2, the left end of steel pipe 3 is carved with external thread, and its right-hand member is radially fixed with and detects pin fixed bar 4, and detecting pin fixed bar 4 is rectangular three-dimensional-structure; Sliding sleeve 6 is " returning " font structure, itself and 4 sliding connections of detection pin fixed bar; Detecting pin 5 is " second " font structure, and its afterbody is fixedly connected with sliding sleeve 6 is vertical; The external thread of steel pipe 3 left ends and the internal thread of threaded guide sleeve 2 match.
On sliding sleeve 6 one sidewalls, have threaded hole, trip bolt 7 is installed in threaded hole; On circular fixed head 1, have 4 through holes; Detect pin 5 and adopt No. 45 steels to do, its diameter is 4mm.
When use, first engine is arranged on as requested to (not dynamometer machine for connecting shaft coupling on test-bed, all the other annex relevant connection bolted put in place), by regulating four legs before and after engine, the centre-height of engine is adjusted to consistent with the centre-height of dynamometer machine with height gauge, after the circular location-plate 1 of this device is fixed on dynamometer machine, according to engine model slip sliding sleeve 6, make the outerplanar of the most advanced and sophisticated head aligning engine flywheel that detects pin 5, after tighten trip bolt 7, adjust the flatness to engine and dynamometer machine by rotation dynamometer machine central shaft.
Below schematically the present invention and embodiment thereof are described, this description does not have restricted, and shown in accompanying drawing is also one of embodiments of the present invention, and actual structure is not limited to this.So, if those of ordinary skill in the art is enlightened by it, in the situation that not departing from the invention aim, without the creationary frame mode similar to this technical scheme and the embodiment of designing, all should belong to protection scope of the present invention.
