Abstract
Description
Technical Field
[0001] The utility model relates to a chamfer dimension measuring auxiliary tool. Background Art
[0002] In the process of gear chamfering and sharp edge chamfering, most of the chamfers are roughly judged by the processing operators and inspectors through visual inspection to see if they meet the requirements. The judgment value and the actual size are affected by human factors and vary greatly. There is no standard chamfering gauge in the national standard series of measuring tools, so it is impossible to make a more accurate judgment for high-precision chamfers, and quality control is difficult. Summary of the invention
[0003] In order to solve the above technical problems, the utility model provides a chamfer dimension measuring auxiliary tool which has a simple structure, low cost, convenient operation and can ensure product quality.
[0004] The technical solution adopted by the utility model is:
[0005] A chamfer dimension measuring aid comprises an L-shaped base and a chamfer measuring plate; the L-shaped base comprises a horizontal plate portion and a vertical plate portion which are perpendicular to each other, the horizontal plate portion is provided with a long straight hole, and the length direction of the long straight hole is perpendicular to the vertical plate portion; one end of the chamfer measuring plate is connected to the long straight hole of the horizontal plate portion by a bolt.
[0006] Furthermore, a guide groove is provided on the transverse plate portion, the guide direction of the guide groove is consistent with the length direction of the long straight hole, and the long straight hole is located at the bottom of the guide groove.
[0007] Furthermore, a guide block is provided on the bolt, the guide block is placed in the guide groove, and the guide block and the chamfer measurement plate are respectively located on both sides of the L-shaped base.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] The utility model has a simple structure and low cost. When the utility model is used, the chamfer measuring plate is rotated to make the chamfer measuring plate close to the chamfered surface of the product and then locked. After the chamfer measuring plate is locked, a vernier caliper is used to measure the linear size of the chamfer, and a universal angle ruler is used to measure the angle. The operation is convenient, and the influence of human factors is greatly reduced, thereby ensuring the quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings.
[0016] like Figure 1-2 and Figure 4-5 As shown, the utility model comprises an L-shaped base 1 and a chamfer measuring plate 2; the L-shaped base 1 comprises a transverse plate portion and a vertical plate portion perpendicular to each other, the transverse plate portion is provided with a guide groove 11 and a long straight hole 12, the guide direction of the guide groove 11 is consistent with the length direction of the long straight hole 12, and the long straight hole 12 is located at the bottom of the guide groove 11; the length direction of the long straight hole 12 is perpendicular to the vertical plate portion. One end of the chamfer measuring plate 2 is connected to the long straight hole 12 of the transverse plate portion by a bolt 3; the bolt 3 is provided with a guide block 4, the guide block 4 is placed in the guide groove, and the guide block 4 and the chamfer measuring plate 2 are respectively located on both sides of the L-shaped base.
[0017] like Figure 3 As shown, when the utility model is used, the utility model is moved to the chamfered position, and the horizontal plate part and the vertical plate part of the L-shaped base 1 are respectively fitted with the two right angle sides of the chamfer. Then the chamfer measuring plate 2 is rotated so that the chamfer measuring plate 2 fits the chamfered surface of the product; then the bolt 3 is tightened. Use a vernier caliper to measure the C value (the C value is the linear dimension of the chamfer), and use a universal angle ruler to measure the angle α value (the α value is the angle dimension).
