Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for processing a flywheel housing. Background Art

[0002] The flywheel housing is a component installed between the engine and the transmission. Its main function is to connect the engine and the transmission together to ensure smooth and reliable power transmission, provide protection for the flywheel and other related parts, and prevent external impurities from entering and damaging internal parts. When processing the flywheel housing, a fixture is needed to clamp the flywheel housing so that it can be processed.

[0003] After searching, the Chinese application number CN202121217543.0 proposes a hydraulic clamp for flywheel housing processing, which relates to the field of mechanical processing, including a mounting plate, a positioning platform and a mounting frame fixedly installed on the top of the mounting plate, three symmetrical circular openings are opened on the top of the positioning platform, and the three circular openings are rotatably connected to rotating rods through bearings, and the tops of multiple rotating rods are fixedly installed with round blocks, and the surfaces of multiple round blocks are fixedly installed with positioning plates, and the bottoms of multiple rotating rods are fixedly installed with driven gears, and a motor is fixedly installed at the top center of the mounting plate. In the above-mentioned existing technology, the flywheel housing is mainly pre-positioned by positioning plates and other methods, so as to facilitate subsequent stable clamping and avoid the flywheel housing from being offset during the clamping process, resulting in the clamping being not centered and affecting subsequent processing.

[0004] In the above-mentioned prior art, a positioning plate is used to position and place the flywheel housing. This method can effectively pre-position the flywheel housing. However, when a hydraulic clamp is used to clamp the flywheel housing, due to the large differences in volume and shape of flywheel housings of different models, when flywheel housings of different shapes appear, the same hydraulic clamp is used to easily result in fewer fits between the clamp and the flywheel housing, and at the same time, the clamping position is asymmetrical on both sides, which leads to poor clamping stability of the flywheel housing by the clamp, thereby affecting subsequent processing. Utility Model Content

[0005] The utility model aims to solve the deficiencies in the prior art and provides a fixture for processing a flywheel housing.

[0006] In order to solve the problem that the above-mentioned traditional flywheel housing processing fixture has a problem that when clamping and fixing the flywheel housing, when clamping flywheel housings of different shapes, due to the different protruding or recessed positions at both ends of some flywheel housings, the clamping force on both sides deviates, which leads to the flywheel housing being easily offset or loosened after clamping, thereby affecting subsequent processing, the utility model solves the problem through the following technical solution.

By setting the second motor 6, the second rotating shaft 61 and the second threaded rod 62, the threaded cylinder 63 can be easily moved.

[0040] Preferably, a threaded barrel 63 is engaged with the outer side of one end of the second threaded rod 62 away from the second rotating shaft 61, and a limiting block 64 is fixedly connected to the outer side of one end of the threaded barrel 63. The limiting block 64 slides in the outer barrel 5 at the end away from the threaded barrel 63.

[0041] Preferably, the end of the threaded barrel 63 away from the second threaded rod 62 is fixedly connected to the connecting plate 7, and the upper end of the connecting plate 7 is fixedly connected to the push plate 71. The connecting plate 7 and the push plate 71 are used to facilitate pushing and adjusting the position of the second clamping plate 8.

[0042] Preferably, a second splint 8 is inserted into the inner side of the first splint 34, and both ends of the second splint 8 are fixedly connected to the limiting plate 81, the end of the limiting plate 81 away from the second splint 8 is inserted in the first splint 34, and a limiting rod 82 is inserted into the middle end of the limiting plate 81, both ends of the limiting rod 82 are fixedly connected to the first splint 34, and a first spring 83 is sleeved on the outer side of one end of the limiting rod 82, the end of the first spring 83 away from the limiting plate 81 is fixedly connected to the first splint 34, and the end of the first spring 83 close to the limiting plate 81 is fixedly connected to the limiting plate 81. By setting two groups of second splints 8, it is convenient to drive the positioning rod 9 and the like to move to clamp the flywheel housing.

[0043] Preferably, a positioning rod 9 is inserted into one end of the second splint 8, and the end of the positioning rod 9 inserted in the second splint 8 is fixedly connected to the second spring 91, and the end of the second spring 91 away from the positioning rod 9 is fixedly connected to the second splint 8. By providing the positioning rod 9 and the second spring 91, it is convenient to limit the flywheel housing by fitting the positioning rod 9 to the flywheel housing.

[0044] As can be seen from the above, when processing the flywheel housing, the flywheel housing is first placed on the base plate 1, and then the positions of the two sets of second clamping plates 8 are adjusted according to the model of the flywheel housing. During the adjustment, when the diameter of the lower end of the flywheel housing is larger than the diameter of the upper end, the first motor 41 is started with the assistance of the housing 4. After the first motor 41 is started, the output shaft drives the first rotating shaft 42 and the gear 43 to rotate, and the outer cylinder 5 is driven to rotate through the engagement of the gear 43 with the gear ring 51. After the outer cylinder 5 rotates, it drives the threaded cylinder 63 to rotate through the limit block 64, thereby using the threaded cylinder 63 to drive the connecting plate 7 and the push plate 71 to rotate. When When the push plate 71 rotates to the second clamping plate 8 at the upper end, the first motor 41 is turned off. Similarly, when the diameter of the upper end of the flywheel housing is larger than the diameter of the lower end, the operation of the first motor 41 drives the connecting plate 7 and the push plate 71 to rotate, so that the push plate 71 rotates to the second clamping plate 8 at the lower end. Then the second motor 6 can be started, and the operation of the second motor 6 drives the second rotating shaft 61 and the second threaded rod 62 to rotate. Then, the second threaded rod 62 engages with the threaded cylinder 63, so that the threaded cylinder 63 pushes the connecting plate 7 and the push plate 71 to move under the restriction of the limit block 64, thereby allowing the push plate 71 to rotate. Push the corresponding second clamping plate 8 to move. When the second clamping plate 8 moves the rod, it drives the limit plate 81 to be sleeved on the outside of the limit rod 82 to move and stretch the first spring 83. When the pushed second clamping plate 8 moves to the appropriate position, the second motor 6 can be turned off. When the diameters of the two ends of the flywheel housing are the same, there is no need to start the second motor 6 for adjustment. After the adjustment is completed, start the single-axis double-headed motor 21. The output shaft of the single-axis double-headed motor 21 drives the single-axis double-headed motor 21 to rotate, so that the threaded plate 31 drives the moving plate 32 and the connecting rod 33 by engaging with the first threaded rod 22 and the threaded plate 31. And the first clamping plate 34 moves, and after the first clamping plate 34 moves, it drives the two groups of second clamping plates 8 to move synchronously. The movement of the second clamping plate 8 drives the positioning rod 9 to approach the flywheel housing. When part of the positioning rod 9 is in contact with the flywheel housing, it is squeezed by the flywheel housing, so that the positioning rod 9 is inserted into the second clamping plate 8 and compresses the second spring 91, and the positioning rod 9 that is not in contact with the flywheel housing continues to be pushed by the second clamping plate 8 to move until the second clamping plate 8 is in contact with the flywheel housing. At this time, the single-axis double-headed motor 21 is turned off, and the flywheel housing is clamped and fixed using the second clamping plate 8 and the positioning rod 9 that is not inserted into the second clamping plate 8.
