Background Art

[0002] At present, the processing technology of bridge housing is mainly completed by CNC equipment. The processing cycle of the reducer installation part of the bridge housing is relatively long. In the case of insufficient equipment production capacity of some bridge factories, it is difficult to meet market demand. It is necessary to transfer the drilling, tapping and other process steps of the reducer installation threaded holes to other equipment for sequential processing. However, the sequential processing is difficult to maintain consistency with the previous positioning reference, resulting in problems such as processing accuracy not meeting the requirements of the drawing and low processing efficiency. Investing a large amount of CNC equipment in a short period of time is high in investment and risky, which is difficult for many small and medium-sized bridge factories to achieve, resulting in loss of market share and reduced sales revenue.

[0005] Furthermore, the height-enhancing seat is connected to a V-shaped positioning block via a linear rail, a sliding block and a bolt.

[0006] Furthermore, the leveling and pressing assembly is connected to the cylinder via a pressing plate and bolts.

[0007] Furthermore, the linear bearing is fixedly connected to the leveling and pressing assembly via bolts.

[0008] The beneficial effects of the utility model are as follows: 1. The processing surface can be automatically leveled and pressed without adjusting the fixture or workpiece, which is consistent with the positioning reference of the previous process; 2. The fixture has a simple structure and can be applied to the production of various types of bridge shells. The operation is convenient and quick, and the processing quality and production efficiency are effectively improved; 3. The fixture is universal, meeting the universality of all bridge shell products, and has the characteristics of low cost and high adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
