Abstract
The invention discloses a four-claw clamping type centering device for an engine simulation experiment and belongs to the field of detection fixtures for automobile components. The four-claw clamping type centering device for the engine simulation experiment comprises a round locating plate, a steel pipe, a claw support and claws, a cylindrical thread connecting sleeve is fixed at the middle of the round locating plate, threads are engraved in the left end of the steel pipe and matched with internal threads in the thread connecting sleeve on the round locating plate, and the right end of the steel pipe is connected with the claw support; the claw support is symmetrical cross-shaped and comprises four extension arm and a middle round substrate; through holes are opened in each of the four extension arms with the same number, and the through holes are opened along the axial direction of the steel pipe; each claw is 1-shaped. By means of the four-claw type design, the detection is more precise and more convenient to perform, and moreover, the claw support is capable of rotating freely, so that a user does not need to rotate a central axis of a dynamometer, and the labor intensity is lowered.
Description
Technical field
The invention belongs to the detection frock field of auto parts and components, more particularly, relate to a kind of four paws clamping type centralising device of simulation of engine 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, as engine flywheel periphery sweeping method, need to manually stir the central shaft of dynamometer machine, and the detection radius of its front-end detection part is unadjustable in the time detecting, and relatively requires great effort, and has increased operating personnel's difficulty.
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 four paws clamping type centralising device of simulation of engine experiment, it makes to detect more accurate and convenient by the design of four paws type, and claw bearing part can rotate freely, without the central shaft that goes to rotate on dynamometer machine, reduce labour intensity.
2, technical scheme
In order to address the above problem, the technical solution adopted in the present invention is as follows:
A kind of four paws clamping type centralising device of simulation of engine experiment, comprise circular location-plate, the middle part of described circular location-plate is fixed with columniform threaded connecting sleeve, also comprise steel pipe, claw bearing and claw, the left end of described steel pipe is carved with screw thread, described screw thread matches with the internal thread of the threaded connecting sleeve on circular location-plate, and the right-hand member of described steel pipe is connected with claw bearing; Described claw bearing is symmetrical " ten " font structure, comprises the circular substrate at an extension arm and middle part, in described circular substrate, is rotationally connected by bearing and steel pipe are installed; On described 4 extension arms, have the through hole of equal number, the direction of described through hole is axial along steel pipe; Described claw is " 1 " font structure, and its bottom is fixed with threaded post, and the size of described threaded post matches with the through hole on claw bearing.
Further, described claw has 4; Through hole on every extension arm of described claw bearing has 4.
Further, described in, state in the threaded post of claw bottom nut is installed.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
Between location-plate of the present invention and steel pipe, adopt and be threaded, easy accessibility is changed at any time; Claw bearing adopts bearing to be connected with steel pipe part, when detection, only need rotate claw bearing part, rotate the central shaft on dynamometer machine without effort, make to detect more flexible, easy, and by the design of four paws type, the flywheel on engine is positioned, four paws part can be on claw bearing layout regulation, to adapt to the detection of different model engine, improved accuracy, the stability of testing process; It is reasonable in design, cost of manufacture is low, easy and simple to handle, practical.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of claw 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 four paws clamping type centralising device of simulation of engine experiment, comprise circular location-plate 1, the middle part of circular location-plate 1 is fixed with columniform threaded connecting sleeve, also comprise steel pipe 2, claw bearing 3 and claw 4, the left end of steel pipe 2 is carved with screw thread, and screw thread matches with the internal thread of the threaded connecting sleeve on circular location-plate 1, and the right-hand member of steel pipe 2 is connected with claw bearing 3; Claw bearing 3 is " ten " font structure, comprises the circular substrate at 4 extension arms and middle part, in circular substrate, is rotationally connected by bearing and steel pipe 2 are installed; 4 extension arms have the through hole of equal number, and the direction of through hole is axial along steel pipe 2; Claw 4 is " 1 " font structure, and its bottom is fixed with threaded post 5.
Claw 4 has 4; Through hole on every extension arm of claw bearing 3 has 4; In the threaded post 5 of claw 4 bottoms, nut is installed.
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, regulate the installation site of claw 4 on claw bearing 3 according to engine model, make claw 4 aim at the outerplanar of engine flywheel, adjust the flatness to engine and dynamometer machine by rotary pawl bearing 3.
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.
