[0002] In the field of motor manufacturing, especially when processing 072 motors, such as Figure 3 The motor end cover 10 shown in the figure often has processing problems such as hole position deviation during the drilling process due to the lack of suitable clamping tooling. Most of the existing various types of end cover drilling tooling are centered on the straight mouth, and are clamped with cylindrical pins and pressure plates to perform the drilling process. The prior art also discloses a motor end cover processing tooling, the publication number of which is CN216096570U, which includes a base, a placement plate is fixed on the base, and the placement plate is provided with placement holes that are compatible with the motor end cover slots; the base is provided with cylinders on both sides of the placement plate, and the cylinders of the cylinders The lower end of the body is hinged on the base, the piston rod of the cylinder is hinged with a clamping block, the support point of the clamping block is set on the placement plate, the piston rod of the cylinder pushes up one end of the clamping block, and the other end of the clamping block presses the front cover of the motor downward, and the pneumatic structure is used to clamp or release the workpiece, which makes the workpiece placement more efficient. However, although this tooling has improved the processing efficiency to a certain extent, its structure is relatively complex, which increases the manufacturing cost and maintenance difficulty. More importantly, the tooling is still insufficient in positioning accuracy and clamping reliability, and it is difficult to meet the needs of high-precision processing. Utility Model Content

[0003] In order to solve the above-mentioned technical problem or one of the technical problems existing in the prior art, the utility model discloses a motor end cover drilling tool, including a base, the edge of the top surface of the base is integrally fixed with a support block, the outer side surface of the support block is provided with a right-angle groove, the outer side surface of the right-angle groove is provided with a side baffle, the side baffle is connected to the side of the right-angle groove by screws, a positioning shaft is provided at the center of the top surface of the base, a steel sleeve is provided on the positioning shaft, a pressure plate is provided on the top of the positioning shaft, and the pressure plate is connected to the positioning shaft by screws.

[0004] Furthermore, the base is circular, and the support block is a discontinuous arc.

[0005] Furthermore, a circular protrusion is provided at the center of the top surface of the base, the bottom surface of the positioning shaft is provided in a groove engaged with the protrusion, and the bottom of the positioning shaft is fixedly connected to the base by screws.

[0006] Furthermore, the top surface of the support block is provided with four U-shaped grooves in a circumferential array, and mounting screw holes are provided in the U-shaped grooves.

[0007] Furthermore, the side baffle is rectangular, and a stopper is fixedly connected to the top of the inner side of the side baffle, and the stopper is arranged above the support block.

[0008] Compared with the prior art, the utility model is ingeniously designed. The support block fixed on the base has a right-angle groove, which is convenient for installing side baffles to adapt to workpieces of different sizes. The fixation with side baffles is more reliable than pin positioning. The combined structure of the locating shaft, steel sleeve and pressure plate ensures the precise positioning and stable clamping of the workpiece, which is more accurate than straight-mouth positioning, thereby significantly improving the efficiency and accuracy of drilling processing, demonstrating excellent practicality and efficiency. By replacing the locating shaft and steel sleeve, it can also be used for various models. BRIEF DESCRIPTION OF THE DRAWINGS
