[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. During the processing of bearings, positioning devices are required to position and fix the bearings. Existing positioning devices for bearing processing usually use flat-jaw pliers, chucks, etc. to fix engine parts. However, during the processing, the engine parts may become unstable due to mechanical vibration, causing them to shake during processing and affecting the processing effect. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a machining fixture for bearing casting, which solves the problem that the positioning device for bearing machining usually uses flat-jaw pliers, chucks and other methods to fix engine parts. However, during the machining process, the engine parts will become unstable due to mechanical vibration, causing them to shake and affecting the machining effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a machining fixture for bearing casting, comprising a worktable, with support plates fixedly connected to both ends of the top of the worktable, a fixing device provided on one side of the top of the support plates, the fixing device including a connecting plate, a connecting box fixedly connected to one side of the connecting plate, the connecting box being fixedly connected to the support plate, an electric telescopic rod fixedly connected inside the connecting box, a support column provided inside the connecting plate, one end of the support column being fixedly connected to one end of the electric telescopic rod, a base fixedly connected to one end of the support column, several T-shaped blocks fixedly connected to the bottom end of the base, connecting blocks provided on both sides of the T-shaped blocks, connecting shafts provided at both ends of one side of the connecting blocks, the connecting shafts passing through the T-shaped blocks and the connecting blocks, a fixing block provided at one end of the inner side of the connecting block, the connecting shafts passing through the fixing block, a clamping block fixedly connected to one end of the fixing block, a support block provided on one side of the clamping block, a pin provided at one end of the support block, the pin passing through the support block and the clamping block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This machining fixture for bearing casting consists of clamping blocks, an electric telescopic rod, a T-block, a support column, a base, a connecting block, and a fixing block. When the bearing needs to be machined, the bearing is first placed between the clamping blocks. Then, the electric telescopic rod applies force to the support column, which in turn moves the base. The base moves the T-block, which in turn moves the connecting block, which in turn moves the fixing block, and finally, the fixing block moves the clamping blocks. This fixes the bearing in place, preventing it from shifting during machining and affecting the machining accuracy.

[0011] 2. This machining fixture for bearing casting, by setting up a threaded rod, a slider, a groove, and a connecting column, allows for the machining of bearings. First, the bearing is placed in the fixing device and fixed. Then, the rotary motor is turned on and rotated, causing the rotary motor to drive the threaded rod to rotate. The threaded rod drives the slider to move within the groove. The slider drives one of the support plates to move. The support plates drive the fixing device to move. The fixing device then drives the bearing to move. Finally, the drive motor is turned on and rotated, causing the drive motor to drive the connecting column to rotate. The connecting column drives the grinding wheel to rotate, thus machining the bearing and providing convenience for the user. Attached Figure Description
