Detailed implementation mode

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] As Figures 1 - 5 shown, the present invention provides a technical solution: a clamping and positioning tooling inside a flywheel housing, including a positioning seat 1. A groove 101 is opened at the top of the positioning seat 1. A fixing frame 11 is fixedly connected to the top of the positioning seat 1. A first screw rod 2 is movably installed inside the groove 101. A clamping plate 3 is arranged inside the groove 101. A movable frame 4 and a connecting plate 5 are respectively arranged at the top of the positioning seat 1. A cavity 501 is opened inside the connecting plate 5. A movable block 6 is arranged inside the cavity 501. A driving motor 7 is fixedly installed inside the positioning seat 1. Sliding grooves 102 are opened on both sides of the inner wall of the groove 101. A rubber pad 31 is fixedly connected to one side of the clamping plate 3. A threaded sleeve 32 is fixedly connected to the bottom of the rubber pad 31. Sliders 33 are fixedly connected to both sides of the threaded sleeve 32. The surface of the threaded sleeve 32 is threadedly connected to the inner wall of the first screw rod 2. The sliders 33 are slidably installed inside the sliding grooves 102.

[0025] In this embodiment, the flywheel housing is placed on the top of the positioning seat 1, and the central hole of the flywheel housing is sleeved on the surface of the movable frame 4. Then, the first screw rods 2 in all directions are rotated, so that the threaded sleeve 32 moves on its surface, and the sliders 33 on the side of the threaded sleeve 32 slide inside the sliding grooves 102. At this time, the clamping plate 3 at the top of the threaded sleeve 32 gradually fits towards the outside of the flywheel housing and clamps and positions the flywheel housing. The rubber pad 31 on the side of the clamping plate 3 can reduce the wear in contact with the flywheel housing. Since the moving distance of each clamping plate 3 can be adjusted, it is convenient to clamp and fix the flywheel housing with an irregular shape.

[0026] Embodiment 2

[0027] As Figures 1 - 5 shown, a second screw rod 71 is fixedly connected to the output end of the driving motor 7. The second screw rod 71 movably penetrates through the inside of the fixing frame 11. The inner wall of the movable frame 4 is threadedly connected to the surface of the second screw rod 71. A first rotating rod 12 is movably installed on the side of the fixing frame 11. A second rotating rod 41 is movably installed on the side of the movable frame 4. One side of the outer wall of the connecting plate 5 is fixedly connected with an engaging block 51. The side of the engaging block 51 is movably connected to the top of the first rotating rod 12 and the bottom of the second rotating rod 41 respectively. One side of the movable block 6 is fixedly connected with a spring 61. The spring 61 is fixedly installed inside the cavity 501.

[0028] In this embodiment, after fixing the outer side of the flywheel housing, the driving motor 7 is started to drive the second screw rod 71 to rotate, so that the movable frame 4 moves on the surface of the second screw rod 71. When the movable frame 4 moves downward, it will drive the second rotating rod 41 on the side to rotate. Through cooperation with the first rotating rod 12, it will push the connecting plate 5 outwards, so that the movable block 6 fits with the central hole of the flywheel housing. When the shape of the central hole of the flywheel housing is irregular, other movable blocks 6 will be squeezed and contract into the cavity 501 and squeeze the spring 61. When the spring 61 is compressed and deformed, it has an outward thrust, so that the movable block 6 abuts against the central hole of the flywheel housing, thereby improving the stability during the clamping process of the flywheel housing. At the same time, the connecting plate 5 is located inside the center of the flywheel housing, which can prevent the flywheel housing from falling off the top of the positioning seat 1.

[0029] The working principle of this embodiment: Place the flywheel housing on the top of the positioning seat 1, and then rotate the first screw rods 2 in all directions, so that the clamping plates 3 gradually fit against the outer side of the flywheel housing to clamp and position the flywheel housing. The rubber pads 31 on the sides of the clamping plates 3 can reduce the wear in contact with the flywheel housing. The central hole of the flywheel housing is sleeved on the surface of the movable frame 4. Then the driving motor 7 is started to drive the second screw rod 71 to rotate, so that the movable frame 4 moves downward and drives the second rotating rod 41 on the side to rotate. Through cooperation with the first rotating rod 12, it will push the connecting plate 5 outwards, so that the movable block 6 fits with the central hole of the flywheel housing, thereby improving the stability during the clamping process of the flywheel housing.

[0030] The above is only a preferred embodiment of the present invention, and is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
