Description

Technical Field

[0001] The utility model relates to the technical field of cam processing, in particular to a cam processing inspection tool. Background Art

[0002] Cam refers to a mechanical rotating or sliding part (such as a wheel or a protruding part of a wheel), which transmits motion to a roller moving close to its edge or a needle bar moving freely on the groove surface, or it receives force from such rollers and needle bars. The detection of the moving linear length of the cam rotation requires certain inspection fixtures to detect it during processing.

[0003] In the prior art, in a patent application entitled "A Cam Processing Inspection Fixture" with an authorization publication number of CN219624648U and an authorization publication date of 2023-09-01, a cam is placed outside the support plate, and the movable ring is further pressed, so that the support plate can be driven to move through the hinged rotation of the first hinge rod and the second hinge rod, and then the inner wall of the cam is squeezed and positioned through the support plate, and the first conical tooth is further driven to rotate through the rotation of the driving shaft, and the driven shaft and the rotating plate are further driven to rotate through the second conical tooth, so that the cam is driven to rotate through the rotation of the support assembly, and the displacement of the guide column by the cam can be observed through the detection plate;

[0004] During the actual use of the above device, since it is inconvenient for the cam to drive the guide column to move in the opposite direction, it is necessary to ensure that the cam is in contact with the guide column at the shortest radius before detection, and since the detection plate is fixed on the vertical plate, it is inconvenient for the staff to carry out the next detection operation.

[0005] Therefore, we proposed a cam processing inspection fixture to solve the above problems. Utility Model Content
