Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, and particularly relates to a special fixture for the installation position degree of automobile parts. Background Art

[0002] The generator end cover is one of the important components used in automobile generators. During its processing, high precision requirements are imposed. If deviations occur during the processing, the hole positions of the mounting holes cannot be aligned, resulting in the situation that the generator end cover cannot be installed. As Figure 1-2 shown in the figure of an existing automobile generator end cover, which includes a cover body with an assembly groove opened at the bottom. A positioning groove is opened in the middle of the bottom of the assembly groove, and a central hole is opened at the bottom of the positioning groove. Wings are provided on both sides of the cover body, and mounting holes are opened at both the front and rear ends of the wings. The axis of the central hole needs to be perpendicular to the axis of the mounting hole, and the concentricity of the two mounting holes opposite to each other in the front and back needs to be consistent. However, the common detection method is to use a detector to detect one by one whether the axis of each central hole is perpendicular to the axis of the mounting hole and whether the concentricity of the two mounting holes opposite to each other in the front and back is consistent. However, this operation method has low detection efficiency, not only increasing the workload, but also the measurement results are prone to errors. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a special fixture for the installation position degree of automobile parts to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: A special fixture for the installation position degree of automobile parts, including a base. A boss is provided above the base, and a positioning table is provided at the central position above the boss. On both sides of the boss above the base, a pair of measurement positioning blocks are provided. The pair of measurement positioning blocks are arranged at intervals in the front and back. A pair of through holes penetrating through the front and back are opened in the pair of measurement positioning blocks. The axis of the through hole is perpendicular to the axis of the positioning table, and the axes of the pair of through holes are on the same straight line. A measurement rod that can slide back and forth is inserted into the through hole.

[0005] With the above technical scheme, during measurement, the central hole of the cover body is passed through the boss. Then, if the assembly groove can be covered and aligned with the boss, it proves that the opening position of the central hole is accurate. Since the distance between the pair of measurement positioning blocks is adapted to the front and back width of the wing, the wings on both sides of the cover body are fixed between the pair of measurement positioning blocks. Then, the measurement rod is pushed to slide in the through hole. If the measurement rod is inserted into the corresponding mounting hole of the wing after sliding, it proves that the axis of the central hole is perpendicular to the axis of the mounting hole and the concentricity of the two mounting holes opposite to each other in the front and back is consistent, thereby ensuring that the cover body can be normally installed on the automobile. The detection process is fast, convenient and labor-saving, improving the detection efficiency.

[0006] As a further optimization of the utility model, a copper sleeve is fixed to the inner wall of the through hole.

[0007] By adopting the above technical solution, the copper sleeve has good wear resistance and corrosion resistance. The copper sleeve is arranged between the measuring rod and the through hole to avoid deformation caused by wear between the through hole and the measuring rod, thereby affecting the measurement accuracy.

[0008] As a further optimization of the utility model, the upper surface of the boss is provided with a first groove on both sides of the front and rear of the positioning platform, and the upper surface of the boss is provided with a second groove on both sides of the front and rear of the positioning platform.

[0009] By adopting the above technical solution, the first groove and the second groove are provided, so that the internal stress generated when the boss is quenched during the processing can be released, thereby avoiding deformation of the boss due to the internal stress and affecting the accuracy of measurement.

[0010] As a further optimization of the utility model, a plurality of supporting feet are provided at the bottom of the base, and the positions of the plurality of supporting feet are arranged one by one with the positions of the boss and the measuring positioning block.

[0011] By adopting the above technical solution, the support foot supports the boss and the measuring positioning block, so that the force on the base is more balanced, avoiding the deformation of the inner base and affecting the accuracy of the measurement.

[0012] As a further optimization of the present invention, a chamfer is provided on the top of the positioning platform.

[0013] With the above technical solution, when the center hole of the cover body passes through the boss, a chamfer is provided to prevent the two from being worn and deformed due to collision.

[0014] As a further optimization of the utility model, a handle is provided at one end of the pair of measuring rods facing each other and away from each other, the diameter of the handle is larger than the inner diameter of the through hole, and the surface of the handle is provided with diagonal anti-slip patterns.

[0015] As a further optimization of the utility model, magnets are provided at opposite ends of the pair of measuring rods facing each other front and back.

[0016] By adopting the above technical solution, the handle facilitates the operation and holding of the measuring rod. When the gauge is not measuring, the opposite ends of the front and rear measuring rods are adsorbed by magnets, and the other ends away from the measuring rods are prevented from falling out because the outer diameter of the handle is larger than the inner diameter of the through hole, thereby keeping the measuring rod fixed.

[0017] The beneficial effects of the present utility model are as follows: during measurement, the central hole of the cover body is passed through the boss. Then, if the assembly groove can be aligned and covered with the boss, it proves that the opening position of the central hole is accurate. Since the distance between a pair of measurement positioning blocks is adapted to the front and rear width of the wing plate, the wing plates on both sides of the cover body are fixed between the pair of measurement positioning blocks. Then, the measurement rod is pushed to slide in the through hole. If the measurement rod slides and is inserted into the corresponding mounting hole of the wing plate after sliding, it proves that the axis of the central hole is perpendicular to the axis of the mounting hole and the concentricity of the two mounting holes opposite to each other in the front and rear directions is consistent, thereby ensuring that the cover body can be normally installed on the vehicle. The detection process is fast, convenient and labor-saving, improving the detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
