Description

Technical Field

[0001] The invention relates to the technical field of a fixture for machining a universal joint fork end surface, and in particular to a fixture for machining a universal joint fork end surface and a use method thereof. Background Art

[0002] The clamp for machining the end face of the automobile universal joint fork is a tool used to stabilize and fix the universal joint fork during the machining process. This type of clamp ensures that the workpiece (universal joint fork) maintains the correct position and angle during the machining process to achieve high-precision machining results. However, when clamping the workpiece, the usual clamp can only simply limit the fixation effect, and cannot flip the clamped workpiece and adjust the height according to the needs of the worker. When it is necessary to process the delicate position, the worker needs to bend down and lie down to observe the delicate position closely. Long working hours can easily cause the worker's waist to be too tired, increasing the labor burden. At the same time, when different positions need to be processed, different positions can only be converted by disassembly and reinstallation, which reduces the applicability of the clamp and needs to be optimized and improved.

[0018] S3: When it is necessary to clean the waste generated by processing, the waste falls to the position of the material bin through the material trough of the material discharging plate, and then the rotating rod is driven to rotate by the bevel gear A, so that the rotating rod drives the roller brush to rotate inside the material bin, so that the waste is automatically discharged from the position of the material discharging bin. When it is necessary to suck out the fine debris in the waste, the dust suction fan can be used to suck the debris from the position of the air inlet plate and the air inlet pipe, and then the debris is transported to the inside of the connecting block through the position of the air outlet pipe;

[0019] S4: When the metal debris needs to be collected and cleaned, the buckle can be grasped and rotated to rotate the buckle at the position of the collection box, and then the handle is grasped and pulled to slide the collection box out from the inside of the connecting block to clean the debris.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are:

[0021] 1. In the present invention, by setting a lifting mechanism and an adjusting mechanism, the position of the workpiece can be smoothly adjusted. By adjusting the height, it is avoided that the workers have to bend down and lie down to observe the detailed position closely, which may easily lead to excessive fatigue of the workers' waist due to long working hours. By adjusting the flipping of the workpiece, the steps of disassembly and reinstallation are saved, and the workpiece can be smoothly rotated and flipped, which improves the convenience of workpiece processing in actual use and also improves the applicability of the fixture.
