Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a vertical parallelism inspection tool for automobile parts. Background Art

[0002] The generator end cover is one of the important parts for automobile generators. It has high precision requirements in its processing. If there is a deviation in the processing, the hole positions of the mounting holes will not be aligned, resulting in the generator end cover being unable to be installed. Figure 1-2 The figure shows an existing automobile generator end cover, including a cover body with an assembly groove at the bottom, an assembly plane at the middle bottom of the assembly groove, a center hole at the assembly plane, fixing holes at both ends, and a plurality of mounting holes vertically penetrating the cover body on the surface, wherein the axis of the mounting hole is perpendicular to the extension line of the assembly plane. A commonly used detection method is to use a detector to detect whether each mounting hole is perpendicular to the cover body one by one, but this operation method is not efficient, not only increasing the workload, but also prone to errors in the measurement structure. Utility Model Content

[0003] The utility model aims to provide a vertical parallelism inspection tool for automobile parts to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: a vertical parallelism inspection tool for automobile parts, comprising a base, a plurality of support blocks are arranged at the bottom of the base, fixed blocks are arranged at the two ends above the base, a table is arranged in the middle, an abutment plane is arranged above the table, a plurality of positioning holes are arranged on the surface of the base which penetrate the base, the abutment plane is arranged perpendicular to the axial direction of the positioning holes, the plurality of support blocks are arranged staggered with the plurality of positioning holes, and a plurality of positioning rods are also included, and the diameters of the plurality of positioning rods are arranged in a one-to-one correspondence with the inner diameters of the plurality of positioning holes.

[0005] By adopting the above technical scheme, the base is placed above a standard horizontal plane. The base is supported by the support block and is in a lifted state. During inspection, the assembly groove of the cover body is facing downward, and the cover body is aligned and fixed with the base through the fixing hole and the fixing block. At the same time, the assembly plane is in contact with the abutment plane of the table top. At this time, the multiple mounting holes on the cover body are aligned with the multiple positioning holes on the base one by one, and the positioning rod is passed through the mounting hole and the corresponding positioning hole from above in turn. At this time, observe whether the positioning rod extends from the bottom of the base. If the positioning rod is observed to extend, it can be determined that the positioning hole is parallel to the axis of the corresponding mounting hole, and whether the mounting hole is perpendicular to the cover body is proved in turn, thereby ensuring that the cover body can be normally installed on the car. The inspection process is fast, convenient and labor-saving, thereby improving the inspection efficiency.

[0006] As a further optimization of the present utility model, a lighting lamp is provided inside the support block; further included are a switch for controlling the on / off of the lighting lamp and a power source for supplying power to the lighting lamp.

[0007] With the above technical solution, when it is detected that the ambient light is insufficient, the lighting lamp can be lit through the switch, thereby illuminating the area below the base, facilitating the observation of whether the positioning rod extends from below the base.

[0008] As a further optimization of the present utility model, a connecting column is vertically provided above the tabletop. The connecting column is provided with an external thread and is sleeved with a connecting ring through a thread. The outer diameter of the connecting ring is smaller than the diameter of the central hole. A plurality of pressing rods are provided on the side wall of the connecting ring along the circumferential direction. Each pressing rod extends in the radial direction. The length of the pressing rod and the outer radius of the connecting ring are greater than the radius of the central hole.

[0009] With the above technical solution, after the cover body is fixed to the base, the connecting ring is sleeved on the connecting column and rotated downward until a plurality of pressing rods abut against the upper part of the cover body, thereby closely fitting the abutting plane of the assembly plane and the tabletop, improving the accuracy of detection.

[0010] As a further optimization of the present utility model, a convex ring is provided at the end of the positioning rod, and the diameter of the convex ring is greater than the diameter of the positioning rod.

[0011] With the above technical solution, the convex ring prevents the positioning rod from falling after passing through the installation hole and the positioning hole, playing the role of limiting and anti-falling.

[0012] The beneficial effects of the present utility model are as follows: The base is placed above a standard horizontal plane. Supported by the support block, the base is in a lifted state. During detection, the assembly groove of the cover body faces downward. The cover body is aligned and fixed with the base through the insertion and cooperation of the fixing holes and the fixing blocks. At the same time, the abutting plane of the assembly plane and the tabletop is fitted. At this time, the multiple installation holes on the cover body are aligned with the multiple positioning holes on the base one by one. The positioning rod is sequentially passed through the installation hole and the corresponding positioning hole from above. At this time, observe whether the positioning rod extends from below the base. Thus, if it is observed that the positioning rod extends, it can be determined that the axes of the positioning hole and the corresponding installation hole are parallel, and it can be proved in turn whether the installation hole is perpendicular to the cover body, 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

[0024] The principle of the present utility model is as follows: Place the base 2 above a standard horizontal plane. Supported by the support blocks 3, the base 2 is in a lifted state. During detection, place the cover body 1 with the assembly groove facing downwards. The cover body 1 is aligned and fixed with the base 2 through the insertion and cooperation of the fixing holes 11 and the fixing blocks 4. At the same time, the assembly plane is in close contact with the abutting plane 211 of the table top 21.
