[0002] The engine flywheel housing is a key housing component installed on the outside of the engine flywheel. It plays a role in supporting and protecting the flywheel, while also serving as a bridge connecting the engine and transmission, providing installation positions for power transmission-related components, and reducing the corrosion of the flywheel and surrounding components by external dust and debris to a certain extent, thus ensuring the stability and reliability of engine power transmission.

[0003] During the processing of flywheel housing, tooling fixtures are used to position the flywheel housing. Traditional fixtures use pneumatic rods to drive clamping plates to position the flywheel housing. The clamping plates are usually straight or curved plates, which result in full contact between the two irregular surfaces of the flywheel housing, leading to reduced stability after the flywheel housing is fixed.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a tooling fixture for the production of engine flywheel housings. (Refer to...) Figures 1 to 4 A tooling fixture for producing engine flywheel housings includes a base plate 1, and a fixing mechanism 2 is provided on the top of the base plate 1.

[0026] The fixing mechanism 2 includes a sliding groove 201, which is formed on the top of the base plate 1. There are several sliding grooves 201. A contact rod 202 is slidably connected to the inner cavity of the sliding groove 201. A tough cloth 203 is fixedly installed at one end of the contact rod 202. A support frame 204 is fixedly installed on the top of the base plate 1. A lead screw 205 is threadedly connected to the inner wall of the support frame 204. A pressing plate 206 is rotatably connected to one end of the lead screw 205. The bottom of the pressing plate 206 cooperates with the top of the contact rod 202. By setting the fixing mechanism 2, the contact rod 202 can be self-adaptively extended. With the pressing plate 206 and the extensible tough cloth 203 driven by the lead screw 205, it can accurately adapt to irregular curved surfaces, ensure uniform force at multiple points, and avoid damage to the workpiece surface through elastic buffering. It supports rapid changeover and significantly improves the stability, efficiency and versatility of fixing complex parts.

[0027] Reference Figure 3 The inner side of the support frame 204 is provided with a guide groove 3, and a guide block 4 is fixedly installed on the surface of the extrusion plate 206. The surface of the guide block 4 is slidably connected to the inner cavity of the guide groove 3. Through the slidable connection between the guide groove 3 and the guide block 4, the movement of the extrusion plate 206 can be guided, so that the extrusion plate 206 can move up and down while remaining vertical.

[0028] Reference Figure 1 and Figure 5 The top of the base plate 1 is fixedly equipped with eight fixing blocks 5, arranged in pairs. Each pair of fixing blocks 5 has a guide rod 6 fixedly installed on opposite sides. A push plate 7 is slidably connected to the surface of the guide rod 6. A through hole 8 is formed at the bottom of the push plate 7, and a rotating groove 9 is formed on the inner wall of the through hole 8. A rotating rod 10 is rotatably connected to the inner wall of the rotating groove 9. A baffle 11 is fixedly installed on the surface of the rotating rod 10, and a torsion spring 12 is sleeved on the surface of the rotating rod 10. One end of the torsion spring 12 is fixedly connected to the surface of the baffle 11, and the other end of the torsion spring 12 is fixedly connected to the rotating groove 9. The inner wall is fixedly connected. Through the cooperation of the push plate 7, the torsion spring 12 and the stop block 18, the two push plates 7 move in opposite directions at the same time. The torsion spring 12 has a large elastic coefficient, which can push multiple contact rods 202 to move in the inner cavity of the sliding groove 201. When the contact rod 202 contacts the flywheel housing, the flywheel housing blocks the rotating rod 10 to rotate in the inner cavity of the rotating groove 9, thereby stopping the stop block 18 from blocking the sliding block until all the contact rods 202 are in contact with the surface of the flywheel housing, thus realizing the synchronous movement of multiple contact rods 202.

[0029] Reference Figure 6A connecting frame 13 is fixedly installed at the bottom of the base plate 1. A bidirectional screw 14 is rotatably connected to the inner wall of the connecting frame 13. A moving hole 15 is opened at the top of the base plate 1. A moving rod 16 is slidably connected to the inner cavity of the moving hole 15. The top of the moving rod 16 is fixedly connected to the bottom of the push plate 7. By setting the bidirectional screw 14, the connecting frame 13 supports the bidirectional screw 14. By rotating the bidirectional screw 14, the connecting frame 13 can move in the inner cavity of the moving hole 15, thereby realizing the simultaneous movement of the two push plates in opposite directions.

[0030] Reference Figure 6 The inner side of the connecting frame 13 is provided with a slot 17. The inner cavity of the slot 17 is slidably connected to the surface of the moving rod 16. By providing the slot 17, the movement of the moving rod 16 can be guided, so that the moving rod 16 can move laterally.

[0031] Reference Figure 6 A stop 18 is fixedly installed on the surface of the bidirectional screw 14. The stop 18 is used in conjunction with the surface of the moving rod 16. By setting the stop 18, the distance that the moving rod 16 moves can be limited, and excessive movement of the moving rod 16 can be avoided.

[0032] Reference Figure 3 A pressure-reducing pad 19 is fixedly installed at the bottom of the extrusion plate 206. The pressure-reducing pad 19 is made of rubber. By setting the pressure-reducing pad 19, the extrusion pressure of the extrusion plate 206 on the multiple contact rods 202 can be reduced, thus preventing the deformation of the contact rods 202.

[0033] Working principle: The flywheel housing is placed on top of the base plate 1. Rotating the bidirectional screw 14 causes the moving rod 16 to slide within the moving hole 15, which in turn causes the two push plates 7 to move in opposite directions simultaneously. The torsion spring 12 has a large elastic coefficient, allowing the baffle 11 to push multiple contact rods 202 within the sliding groove 201. When the contact rods 202 contact the flywheel housing, the flywheel housing blocks the rotation of the rotating rod 10 within the rotating groove 9, causing the baffle 11 to stop blocking the contact rods 202 until all contact rods 202 are in contact with the surface of the flywheel housing. The moving lead screw 205, by rotating, can drive the extrusion plate 206 to move downward, thereby realizing the overall extrusion and fixation of the moved contact rods 202, thus fixing the position of multiple contact rods 202. The flexible cloth 203 contacts the surface of the flywheel housing. The flexible cloth 203 has extensibility and is made of polyurethane (PU) elastic fabric. It has high elasticity and extensibility and can be stretched after multiple misaligned contact rods 202 are misaligned, thereby increasing the surface contact area between multiple contact rods 202 and the flywheel housing. This allows for stable fixation according to the complex curved surface of the flywheel housing, ensuring the stability of the flywheel housing fixation.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
