Description

Technical Field

[0001] The utility model relates to the field of spring washer processing, in particular to an auxiliary tool for measuring the inner diameter of a spring washer. Background Art

[0002] Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and easy installation, and are suitable for parts that are frequently assembled and disassembled. In the production process of spring washers, it is necessary to measure the inner diameter of the finished spring washers to ensure the qualified rate of the finished products. In the prior art, a go and no-go gauge is usually used to measure the inner diameter of the spring washers, but the go and no-go gauge can only detect whether the corresponding spring washer is within the allowable tolerance range, and cannot specifically measure the inner diameter size of the spring washer.

[0003] When a batch of spring washers inner diameter data is needed for analysis to optimize the assembly line process or processing method, it is measured manually. Due to the spiral posture of the spring washers, it is difficult to ensure that the posture of the caliper is perpendicular to the central axis of the spring washers, which also causes errors in the measured data. For small-sized spring washers, this error has a greater impact on the analysis. Therefore, it is necessary to improve such a structure to overcome the above defects. Utility Model Content

[0009] The utility model is further configured as follows: a first scale is provided on the first supporting block, and the first scale corresponds to the first abutting block.

[0010] In the above technical solution: the first scale is used to identify the angle at which a first abutment block is set, and is used as a reference, so that the angles of another first abutment block and the remaining second abutment blocks can be adjusted to the reference angle.

[0011] The utility model is further configured as follows: a second scale is provided on the second supporting block, and the second scale corresponds to the second abutting block.

[0013] The utility model is further configured as follows: a second positioning bracket is arranged on the first base platform, and the second positioning bracket is arranged corresponding to the first positioning bracket.

[0014] In the above technical solution: the second positioning bracket is used to further ensure the horizontal posture of the measuring device, while preventing it from tilting forward and backward, thereby further improving the measurement accuracy.

[0015] The utility model is further configured as follows: a first positioning groove is provided on the first positioning bracket, a second positioning groove is provided on the second positioning bracket, and the bottom surfaces of the first positioning groove and the second positioning groove are consistent in height.

[0016] In the above technical solution: the first positioning groove and the second positioning groove are used to limit the posture of the measuring instrument to keep it horizontal.
