Description

Technical Field

[0001] This utility model relates to the field of part size measurement technology, and in particular to a part size measurement auxiliary tool. Background Technology

[0002] Parts are the basic units that make up mechanical equipment, electronic products, or engineering structures, and their quality directly affects overall performance, reliability, and lifespan. Part dimensional measurement is a key step in ensuring product quality and performance, involving multiple dimensions such as length, diameter, angle, and geometric tolerances.

[0003] A search revealed that patent CN217953307U discloses a special inspection tool for measuring the dimensions of conical parts. This device can inspect conical parts, but in use, it is limited to measuring the dimensions of similar parts and cannot be adjusted according to the specifications of the parts, thus its use is limited.

[0004] Therefore, we propose a part size measuring tool. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the limited range of measurement equipment for similar parts, the inability to adjust for different parts specifications, and the resulting limitations in application. Therefore, this invention proposes an auxiliary tool for measuring the dimensions of parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A part dimension measuring tool, comprising:

[0008] The base has a placement groove on its surface, a mounting seat is provided in the placement groove, and the outer wall of the mounting seat has multiple grooves of different sizes.

[0009] A fixing base is fixed to one side of the base;

[0010] A slider is slidably connected to the fixed base. The slider is provided with a guide block, and a placement plate is slidably connected inside the guide block. The placement plate is used to place a dial indicator. The slider has a through hole through which the measuring head of the dial indicator passes.

[0011] The desired groove orientation is selected by rotating the mounting base, and the slider height is adjusted to align the dial indicator head with the groove, thus adapting to parts of different sizes.

[0012] In one possible design, the mounting base has multiple mounting holes on both sides, and the slider has second threaded grooves on both sides. The second bolt passes through the mounting holes and is screwed into the second threaded grooves to fix the slider height.

[0013] In one possible design, the bottom of the guide block is threaded with a set screw, the top of which abuts against the bottom of the placement plate to restrict movement of the placement plate.

[0014] In one possible design, a first bolt is provided at the bottom of the mounting base, and a first threaded groove is provided at the bottom of the placement slot. The first bolt is screwed into the first threaded groove to fix the position of the mounting base.

[0015] In one possible design, positioning grooves are provided on both sides of the slider, and positioning strips are fixed on the inner walls of both sides of the fixed base. The positioning strips slide in conjunction with the positioning grooves to guide the slider to move.

[0016] In one possible design, the surface of the mounting base is provided with multiple printed areas, which are marked with dimension information corresponding to the grooves; the two sides of the fixing base are provided with scale lines to indicate the adjustment of the slider height.

[0017] In this application, during use, the posture of the mounting base is adjusted according to the size of the part to be measured, and the corresponding groove is adjusted to face the fixed base. The mounting base is limited by the first bolt, and then the slider is adjusted to a suitable height. The slider is limited by the second bolt, and then the part to be measured is placed on the base surface and attached to the groove. Then, the placement plate is pulled to move the distance, and the dial indicator is placed on the placement plate and passed through the through hole. Then, the placement plate and the dial indicator are pushed to move so that the measuring head of the dial indicator contacts the outer wall of the part to be measured. Then, the set screw is tightened, and then the dial indicator is zeroed. Then, the part is manually rotated to fit the groove. During the rotation, the fluctuation of the dial indicator value is observed to see if it exceeds the threshold. The operation is simple and convenient.

[0018] Beneficial effects: In this utility model, the part size measuring auxiliary tool, through the setting of groove, slider and second bolt and other structures, can adjust the groove and adjust the height of the dial indicator detection head according to the size of the part to be measured. The operation is simple and convenient, and the applicability of the equipment is improved.

[0019] In this utility model, the part size measuring aid, through the setting of structures such as set screws, placement plates and guide plates, enables the dial indicator's detection head to stably contact the part to be measured, and the dial indicator is easy to place.

[0020] In this invention, the groove can be adjusted according to the size of the part to be measured, and the height of the dial indicator head can be adjusted. The operation is simple and convenient, which improves the applicability of the equipment, allows the dial indicator head to stably contact the part to be measured, and makes it easy to place the dial indicator.
