During the processing of the flywheel, its bevel groove needs to be polished, so the flywheel housing needs to be positioned by tooling.

[0003] The existing patent CN 217776667 U is a flywheel housing bevel groove processing and positioning tool. The flywheel housing is placed on a support plate, and the positioning column passes through the through hole in the middle of the flywheel housing. The outer wall of the positioning column is tightly fitted with the inner wall of the through hole in the middle of the flywheel housing. The positioning column exerts force on the inner wall of the flywheel housing and plays a positioning role, so that the placement of the flywheel housing is more accurate and no adjustment is required. When the flywheel housing is placed stably, the clamping rod is rotated by relying on the rotating shaft, so that the clamping rod is rotated to the surface of the flywheel housing, and the lower surface of the clamping rod can be against the upper surface of the flywheel housing, so that the flywheel housing can be fixed, further ensuring the accuracy of the positioning of the flywheel housing.

[0004] However, in the process of using the existing patented flywheel housing bevel groove processing and positioning tooling, the device fixes the flywheel housing through positioning columns and clamping rods, but both are not adjustable, and the through holes in the middle and the overall heights of flywheels of different sizes are different, resulting in the device being unable to perform processing and positioning for flywheel housings of different sizes.

The above-mentioned scheme solves the problem that the above-mentioned device fixes the flywheel housing through the positioning column and the clamping rod, but both of them cannot be adjusted, and the through hole and the overall height in the middle of flywheels of different sizes are different, resulting in the problem that the device cannot perform processing and positioning for flywheel housings of different sizes. It can be understood that this scheme can also be used to solve the problem of locking the positioning rod.

[0023] In this embodiment, by lifting and lowering the fixing seat 107 and rotating and adjusting the positioning rod 106 , the positioning rod 106 can position the flywheel housings 105 of different sizes.

[0024] Among them, the limiting rod 109 is fixedly installed on the supporting column 102 and is located in the positioning cylinder 103, the lifting ring 108 is slidably installed on the limiting rod 109 through the lifting assembly, the fixing seat 107 is fixedly installed on the lifting ring 108 and passes through the limiting groove 104, the positioning rod 106 is rotatably installed on the fixing seat 107 through the locking assembly, the positioning cylinder 103 is a cylindrical structure, the opening of the positioning cylinder 103 faces downward, the limiting rod 109 is welded to the top of the supporting column 102, and the axis of the limiting rod 109 coincides with the axis of the positioning cylinder 103, the inner diameter of the lifting ring 108 is the same as the diameter of the limiting rod 109, the outer diameter of the lifting ring 108 is smaller than the inner diameter of the positioning cylinder 103, the number of the fixing seats 107 is two groups, and they are welded on the lifting ring 10 8, the positioning rod 106 is rotatably matched with the two groups of the fixing seats 107 through the pin shaft. When the flywheel housing 105 passes through the positioning cylinder 103 and is located on the positioning seat 101, the positioning rod 106 is rotated to be parallel to the fixing seat 107, and the positioning rod 106 is locked by the locking assembly. At the same time, the lifting assembly is driven so that the lifting ring 108 drives the fixing seat 107 to move downward, and the fixing seat 107 drives the positioning rod 106 to move downward through the cooperation of the locking assembly until the positioning rod 106 abuts against the upper surface of the flywheel housing 105, thereby realizing the positioning of the flywheel housing 105, and by lifting and lowering the fixing seat 107 and rotating and adjusting the positioning rod 106, the positioning rod 106 can position flywheel housings 105 of different sizes.

[0025] Secondly, the lifting rod 110 is slidably installed in the positioning cylinder 103 through the driving component and is fixedly connected to the lifting ring 108. The number of the lifting rods 110 is four groups, and they are distributed in a ring on the upper surface of the lifting ring 108. The driving component drives the lifting rod 110 to move downward, so that the lifting rod 110 drives the lifting ring 108 to move downward, thereby achieving the movement effect of the lifting rod 110.

[0026] Again, the electric push rod 112 is fixedly installed in the positioning cylinder 103; the driving disk 111 is fixedly installed at the output end of the electric push rod 112 and is fixedly connected to the lifting rod 110.

The anti-slip rod 113 is made of rubber material. Through the setting of the anti-slip rod 113, the friction between the positioning rod 106 and the flywheel housing 105 is increased.

[0028] In this embodiment, when in use, the positioning rod 106 is driven to rotate upward around the fixing seat 107, so that the positioning rod 106 is parallel to the axis of the positioning tube 103, and then the flywheel housing 105 passes through the support column 102 and the positioning tube 103, so that the positioning tube 103 passes through the through hole on the flywheel housing 105, and then the positioning rod 106 is driven to rotate around the fixing seat 107 to a position parallel to the fixing seat 107, and the positioning rod 106 is locked by the locking assembly, and then the electric push rod 112 is started to push the drive disk 111 to move downward, and the movement of the drive disk 111 drives the lifting rod 110 through the fixed connection with the lifting rod 110. 0 moves downward, the lifting rod 110 further pushes the lifting ring 108 to move downward along the limiting rod 109. Since the fixing seat 107 is fixedly connected to the lifting ring 108, the movement of the lifting ring 108 pushes the fixing seat 107 to move downward along the limiting groove 104, and the fixing seat 107 drives the positioning rod 106 to move downward by cooperating with the locking assembly until the positioning rod 106 abuts against the upper surface of the flywheel housing 105, thereby realizing the positioning of the flywheel housing 105, and by lifting and lowering the fixing seat 107 and rotating and adjusting the positioning rod 106, the positioning rod 106 can position flywheel housings 105 of different sizes.

[0031] In this embodiment, the locking effect of the positioning rod 106 is achieved through the cooperation of the locking rod 201 , the spring 202 and the connecting block 203 .

[0032] Among them, a slot 204 is provided on the positioning rod 106, and the locking rod 201 passes through the fixing seat 107; the connecting block 203 is fixedly installed on the locking rod 201; the spring 202 is sleeved on the locking rod 201, and the two ends of the spring 202 are respectively fixedly connected to the connecting block 203 and the fixing seat 107, the slot 204 has the same diameter as the locking rod 201, and the slot 204 passes through the positioning rod 106, the connecting block 203 is a disc-shaped structure, and is welded to the end of the locking rod 201, and when the positioning rod 106 is parallel to the fixing seat 107, the slot 204 is exactly in the same straight line with the locking rod 201. When the positioning rod 106 positions the flywheel housing 105, the locking rod 201 is pulled to the side away from the fixing seat 107 through the connecting block 203. At this time, the spring 202 is pulled and is in a stretched state. Then, the positioning rod 106 is rotated to be parallel to the fixing seat 107, and then the connecting block 203 is loosened, so that the spring 202, under the action of its own elastic force, drives the locking rod 201 to reset and pass through the slot 204, so that the positioning rod 106 cannot rotate, thereby achieving the locking of the positioning rod 106.

[0033] In this embodiment, when the positioning rod 106 positions the flywheel housing 105, the locking rod 201 is pulled to the side away from the fixing seat 107 through the connecting block 203. At this time, the spring 202 is pulled and is in a stretched state. Then, the positioning rod 106 is rotated to be parallel to the fixing seat 107, and then the connecting block 203 is loosened, so that the spring 202, under the action of its own elastic force, drives the locking rod 201 to reset and pass through the slot 204, so that the positioning rod 106 cannot rotate, thereby achieving the locking of the positioning rod 106.
