[0002] During motor assembly, locating pin holes are installed between large components such as the end cap, base, and bearing housing for reassembly and positioning. These holes must be machined after the entire motor is assembled. Common machining methods for these large pin holes include: hoisting the entire motor onto a machine tool for machining, which is very expensive; using a radial drill, which requires ample on-site space, is cumbersome to position and install, and creates a significant workload; and using a magnetic drill, which is compact and easy to operate, but is limited to motor mechanisms and often lacks a suitable magnetic surface.

[0003] The current magnetic drill auxiliary tooling has not been able to solve the problem of processing locating pin holes. For example, Chinese Patent 201921165089.1, the invention name: a magnetic drill fixing device. The device disclosed in this patent is used as a magnetic drill auxiliary tooling, which is mainly used to solve the problem of position offset of the magnetic drill caused by torque during operation. The structure is relatively complex and cannot be applied in terms of spatial position, and still cannot solve the problem of processing locating pin holes.

[0004] Therefore, there is an urgent need for a motor pin hole processing auxiliary tooling that can provide a magnetic adsorption plane for a magnetic base drill and is easy to operate. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a motor pin hole processing auxiliary tooling. When processing the motor pin hole, only bolts are required to be installed on both sides of the motor pin hole, providing a magnetic adsorption plane for the magnetic base drill. It is simple to install and easy to use.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A motor pin hole processing auxiliary tooling includes a sliding rod, an arm lever slider and a suction cup slider; the sliding rod is slidably equipped with two arm lever sliders and a suction cup slider, the suction cup slider is located between the two arm lever sliders, and the bottoms of the two arm lever sliders are respectively fixed with bolt holes on both sides of the motor pin hole, and the arm lever slider and the suction cup slider are both provided with supporting bolts for supporting the sliding rod.

[0008] A further technical solution is that the two ends of the slide bar are respectively provided with a lifting hook along the axial direction of the slide bar, which can prevent the arm lever slider from sliding out and facilitate transportation and lifting.

[0009] In a further technical solution, the cross-section of the slide bar is shaped like a right-angled trapezoid, with its base angle cut parallel to the right-angled side. The top angle of the right-angled trapezoid of the slide bar is between 100° and 120°. That is, the slope of the waist of the right-angled trapezoid relative to the vertical plane is between 10° and 30°, allowing for rapid tightening and loosening, and quick adjustment of the relative position of the arm lever slider and the suction cup slider.

[0010] According to a further technical solution, the suction cup slider includes a slide seat and a disc body arranged on the slide seat, the slide seat is provided with a first slide hole matching the shape of the slide rod, and one side of the slide hole is provided with a first screw hole.

[0011] A further technical solution is that when in use, the suction cup slider remains parallel to the motor pin hole surface, ensuring that the magnetic drill spindle is parallel to the motor pin hole to be processed;

[0012] A further technical solution is that one end of the arm lever slider is provided with a second sliding hole matching the shape of the sliding rod, and the other end is provided with a mounting hole. The mounting hole and the bolt hole on the side of the motor pin hole are connected by bolts and washers to fix the arm lever slider, and a second screw hole is provided on one side of the second sliding hole.

[0013] As a further technical solution, a transition washer is provided between the bolt and the mounting hole, which is suitable for use with different bolt sizes. Beneficial effects

[0014] Compared with the prior art, the present invention has the following significant advantages:

[0015] 1. The utility model can be quickly installed when the magnetic drill is used to process the positioning pin hole, and provides a magnetic adsorption plane for the magnetic drill. It has a simple structure, is easy to use, has a small installation workload, is low in cost, and is highly practical.

[0016] 2. The utility model utilizes the fact that there are two screw holes on both sides of the motor pin hole and sets two arm lever sliders for installation and fixation. During processing, the distance between the arm lever slider and the suction cup slider is adjusted as needed, and the position of the suction cup slider on the slide rod can be adjusted to the maximum extent, so that the utility model can be applied to the processing of motor pin holes of various positions and sizes.

[0027] The cross-section of the slide bar 1 is shaped like a right-angled trapezoid, with its base angle cut parallel to the right-angled sides. The top angle of the right-angled trapezoid is between 100° and 120°. This means the slope of the waist of the right-angled trapezoid relative to the vertical is between 10° and 30°, allowing for quick tightening and loosening, and enabling rapid adjustment of the relative position of the arm lever slider 2 and the suction cup slider 3.

[0028] The suction cup slider 3 includes a slide seat 3-1 and a disc body 3-2 arranged on the slide seat 3-1. The slide seat 3-1 is provided with a first slide hole 3-3 matching the shape of the slide rod, and one side of the first slide hole 3-3 is provided with a first screw hole 3-4.

[0029] When in use, the suction cup slider 3 remains parallel to the motor pin hole surface, ensuring that the magnetic drill spindle is parallel to the motor pin hole to be processed, which is convenient for precise positioning and processing.

[0030] One end of the arm lever slider 2 is provided with a second sliding hole 2-5 that matches the shape of the sliding rod, and the other end is provided with a mounting hole 2-1. The mounting hole 2-1 and the bolt holes 6 on both sides of the motor pin hole 5 are connected by the cooperation of bolts 2-2 and washers 2-3 to fix the arm lever slider 2. A second screw hole 2-6 is provided on one side of the second sliding hole 2-5.

[0031] A transition washer 2-4 is provided between the bolt 2-2 and the mounting hole 2-1, which is suitable for use with different bolt sizes.

[0034] 2. When using, first adjust the position of the two arm sliders on the slide bar to match the distance between the screw holes on both sides of the motor pin hole to be processed, then install the tooling on the screw holes of the motor pin hole by using bolts, washers, and transition washers, and insert the supporting bolt into the second screw hole to tighten;

[0035] 3. Then adjust the position of the suction cup slider on the slide rod so that the distance from the center of the suction cup slider to the center of the pin hole to be processed is consistent with the size of the magnetic drill. Insert the support bolt into the first screw hole and tighten it. Then place the magnetic drill on the disk body of the suction cup slider to process the positioning pin hole. The size of the disk body is slightly larger than the size of the base of the magnetic drill to ensure the stability of the magnetic drill.
