Description

Technical Field

[0001] This utility model relates to the field of automotive repair technology, specifically to an automotive gearbox shift fork inspection tool. Background Technology

[0002] The shift fork is a core component of the automotive transmission control mechanism. Through its design straddling the annular groove of a sliding gear, it enables the transmission connection between the shift lever and the gear. Its main body consists of a baffle plate, washers, and locating pins. The assembly precision directly affects the smoothness and reliability of the transmission's shifting.

[0003] Patent CN217541733U discloses a gearbox shift fork inspection tool, which includes a worktable, a clamping assembly, a top plate assembly, a lubrication assembly, and a shift fork sleeve. The output end of the clamping assembly is engaged with the outer wall of the shift fork sleeve for clamping. This device only requires inserting the shift fork into the shift fork sleeve. When the shift fork is not deformed, it can be smoothly inserted into the shift fork sleeve. When the shift fork is deformed, it cannot be smoothly inserted into the shift fork sleeve, thus identifying whether the shift fork is deformed.

[0004] However, the device only has one set of clamping components on the top of the worktable to hold the shift fork sleeve. This means that after the shift fork sleeve is clamped and limited and inserted for detection, the restriction of the detected shift fork sleeve must be released first, and then it can be removed before a new shift fork sleeve can be inserted for clamping and detection. This operation is cumbersome and affects the detection efficiency. To address this, an automotive gearbox shift fork inspection tool is proposed to solve the problem that the existing shift fork inspection tool is difficult to continuously detect and thus affects the detection efficiency.
