Description

Technical Field

[0001] The utility model relates to a comprehensive inspection tool for the parallelism and position of the left and right ends of a rear axle, belonging to the technical field of inspection tool equipment. Background Art

[0002] Gauges are simple tools used by industrial manufacturers to control various dimensions of products (such as hole diameter, space dimensions, etc.) to improve production efficiency and control quality. They are suitable for mass-produced products, such as automotive parts, to replace professional measuring tools, such as smooth plug gauges, threaded plug gauges, outside diameter calipers, etc. Vernier calipers and depth gauges are measuring tools, not gauges.

[0003] The Chinese patent number CN101726226A is a kind of automobile power steering housing unloading hole position inspection tool, which is composed of a handle, a pin, a guide sleeve, a standard mandrel and a positioning plate. The left end face of the positioning is provided with a handle, and the right end face is provided with a step that matches the clearance of the inner hole at the bottom end of the housing. The end face of the step is provided with a pin that matches the positioning pin hole at the bottom end of the housing. The standard mandrel optical axis section in the present invention matches the unloading hole to be inspected. If the standard mandrel optical axis section is inserted under the positioning condition, the hole position is qualified, otherwise it is unqualified. The entire measurement operation is simple and fast, and is particularly suitable for online detection in workshops.

[0004] However, the existing inspection fixture lacks a mechanism for processing the left and right ends of the parts used in the automobile follow-up rear axle assembly, which is not convenient for comprehensive inspection of the parallelism of the two axes and the position of the connecting holes of the rear axle parts.

[0005] Therefore, a comprehensive inspection fixture for the parallelism and position of the left and right ends of the rear axle is proposed. Utility Model Content

[0006] In view of this, the utility model provides a comprehensive inspection tool for the parallelism and position of the left and right ends of a rear axle to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical scheme of the utility model is realized as follows: a comprehensive inspection tool for the parallelism and position of the left and right ends of the rear axle comprises a base panel, a reference sleeve is installed on the left side of the upper end of the base panel, a guide column vertical rod is installed on the right side of the upper end of the base panel, a part body to be inspected is inserted in the reference sleeve, a plurality of connecting holes are arranged on the outer side of the reference sleeve, the reference sleeve is inserted in the connecting hole, a parallelism bottom plate is arranged on the upper end of the guide column vertical rod, a guide column inner sleeve is arranged on the inner end of the parallelism bottom plate, and a parallelism sleeve is arranged on the left end of the parallelism bottom plate.

[0008] Further preferably, the guide column vertical rod and the reference sleeve and the base panel are in interference fit, and the parallelism bottom plate is inserted into the guide column vertical rod through the guide column inner sleeve.

[0009] Further preferably, a plurality of connection holes are respectively located at triangular locations outside the reference sleeve, and the large end of the body of the part to be inspected can be inserted into the parallelism sleeve.

[0010] Further preferably, a side transverse strip is fixedly connected to the right end of the base panel, and a plurality of upper openings are formed at the upper end of the side transverse strip.

[0011] Further preferably, the plurality of upper openings are equidistantly arranged from front to back, and the plurality of connection hole pins are sequentially passed through the corresponding upper openings.

[0012] Further preferably, the upper end of the connecting hole pin and the upper end of the side cross plate strip are fixedly connected with a connecting semi-arc circle, and a connecting rope is connected between the two corresponding upper and lower connecting semi-arc circles.

[0013] Further preferably, the connecting rope is made of a stretchable material, and the lower end of the base panel contacts an operation detection table.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. This scheme uses various components on the base panel to check the comprehensive position accuracy of the part body to be tested. First, the guide column vertical rod, the reference sleeve and the base panel are interference fit and fixed on the base panel together, and the rod of the part body to be tested is installed in the reference sleeve. The three connecting hole pins are inserted into the three corresponding connecting holes respectively to check the position of the part body to be tested. The parallelism base plate is inserted into the guide column vertical rod through the guide column inner sleeve, and the large end of the part body to be tested is installed in the parallelism sleeve to check the comprehensive effect of the parallelism and position of the rod and the large end of the part body to be tested. The design is simple, practical and convenient, the test effect is perfect, and the operation steps are concise and clear.

[0016] Second, at the same time, a side cross bar can be added to the side of the base panel. A plurality of upper openings can be set on the side cross bar to facilitate the storage and placement of a plurality of connection hole pins on the base panel, so that the placement of the connection hole pins can be limited to avoid the risk of falling and bending due to direct placement on the work surface. At the same time, a connecting rope is set between the upper opening and the connection hole pins. The connecting rope can strengthen the connectivity between the upper opening and the connection hole pins, prompting the operator to develop the effect of returning the connection hole pins to their positions in time.
