[0002] The flywheel housing is an important connecting component between the automotive engine and the transmission. It is usually a sturdy housing, and the flywheel housing is generally made of materials such as cast iron or aluminum alloy. These materials have relatively high strength and rigidity and can withstand the vibrations and impacts generated during engine operation. The structural design of the flywheel housing is also very important. It needs to meet strict tolerance and fitting requirements to ensure accurate connection and sealing with the engine and the transmission.

[0003] During the processing of the flywheel housing, in order to obtain the required shape and appearance, the flywheel housing needs to be processed through multiple steps to ensure that its accuracy, quality, and performance meet the design requirements. When processing the flywheel housing, a fixture is generally required to position the flywheel housing.

[0004] However, the flywheel housing is generally heavy and not convenient to operate the fixture. When placing the processed flywheel housing into the part positioning pin holes of the fixture, it often cannot be accurately placed into the positioning pin holes, and it is easy to knock and scratch the processed surface of the flywheel housing during operation, resulting in defective product scrapping. Therefore, there is an urgent need in the market to develop a lifting mechanism for a product processing fixture to help people solve the existing problems. Content of the Utility Model

[0024] During use, place the flywheel housing on the placement table 5. The second hydraulic cylinder 12 drives the placement table 5 to smoothly descend to the positioning point. Through the positioning frame 9 provided with the positioning posts 903, the flywheel housing can be accurately aligned and successfully positioned, greatly reducing the positioning deviation and risk of bumping caused by improper manual operation. After the flywheel housing is processed, the lifting mechanism body 1 can lift the flywheel housing to avoid scratches on the processed surface due to misalignment during movement, effectively ensuring the product quality.

[0025] Furthermore, there are two limiting side frames 7, which are symmetrically arranged on both sides above the placement table 5 respectively. The limiting side frame 7 includes a vertical plate 701 and a horizontal plate 702. There are two vertical plates 701, which are symmetrically and fixedly installed at the front end and the rear end below the horizontal plate 702 respectively.

There are two limiting posts 8, which are symmetrically and fixedly arranged on both sides at the rear end above the placement table 5 respectively. By providing the two limiting posts 8, the rear end of the flywheel housing body 2 can be limited, which is beneficial to the positioning and placement of the flywheel housing body 2 on the placement table 5.

[0026] Furthermore, there are two cushion posts 6, which are fixedly installed above the placement table 5 and are located between the two limiting side frames 7. The setting of the cushion posts 6 makes the flywheel housing body 2 rest on the two cushion posts 6 when placed on the placement table 5, so as to support the flywheel housing body 2.

[0027] Furthermore, there are two supporting side frames 4, which are symmetrically and fixedly installed on both sides below the table board 3 respectively, and can support the table board 3 to increase the stability of the table board 3.

There are two connecting plates 1003, and the two connecting plates 1003 are respectively symmetrically rotatably installed on both sides of the pressing plate 1002. The base 1004 is rotatably installed below between the two connecting plates 1003, and the base 1004 is fixedly connected to the cylinder block of the first hydraulic cylinder 1001. By providing the pressing assembly 10, after the flywheel housing body 2 is placed on the placement table 5 and moves down for positioning, the piston rod of the first hydraulic cylinder 1001 is ejected, so that the end of the pressing plate 1002 can press on the edge of the flywheel housing body 2, assisting in pressing the flywheel housing body 2 to prevent the flywheel housing body 2 from shaking, which is beneficial to the accuracy of flywheel housing processing.

[0030] Working principle: During use, the flywheel housing is placed on the placement table 5. The flywheel housing is jointly limited by the symmetrically arranged limiting side frames 7 on both sides and the symmetrically arranged limiting columns 8 at the rear to ensure positioning on the placement table 5. Then, the second hydraulic cylinder 12 drives the placement table 5 to move down, and the positioning columns 903 on the plurality of positioning frames 9 are used to cooperate with the flywheel housing to achieve accurate alignment, effectively avoiding positioning deviation and knocking caused by improper manual operation. After positioning, the first hydraulic cylinder 1001 in the pressing assembly 10 is started, so that the end of the pressing plate 1002 can press on the edge of the flywheel housing body 2, assisting in pressing the flywheel housing body 2 to prevent the flywheel housing body 2 from shaking and improving the processing accuracy. After processing, the second hydraulic cylinder 12 drives the placement table 5 to move up, and then the flywheel housing is lifted up to facilitate blanking.
