[0027] Furthermore, the transmission cover 100 is provided with a receiving cavity 140 for installing the shifting mechanism. The first shaft hole 110 and the second shaft hole 120 are respectively provided on both sides of the receiving cavity 140, the first shaft hole 110 is provided as a through hole, and the second shaft hole 120 is provided as a blind hole. The shifting mechanism is installed in the receiving cavity 140, and then the shifting shaft extends from the first shaft hole 110 into the receiving cavity 140 and is passed through the shifting mechanism to fix the shifting mechanism in the receiving cavity 140, and the end of the shifting shaft is embedded in the second shaft hole 120 to fix the shifting shaft, which has a simple structure and is easy to operate.

[0028] It is conceivable that the edge of the transmission cover 100 is provided with a mounting hole 160 for connecting with the transmission housing via bolts, thereby improving the stability of the connection between the transmission cover 100 and the transmission housing.

[0029] Reference Figures 2 to 4The embodiment of the present application provides a transmission cover comprehensive inspection tool for inspecting the transmission cover 100. The transmission cover comprehensive inspection tool comprises: a base plate 200; a detection mechanism, which is arranged on the base plate 200, and the detection mechanism comprises a first fixing seat 310, a second fixing seat 320 and a fixed shaft 330, the first fixing seat 310 and the second fixing seat 320 are arranged alternately, the first fixing seat 310 is provided with a first detection hole 340, the second fixing seat 320 is provided with a second detection hole 350, the first detection hole 340 and the second detection hole 350 are arranged coaxially, the first detection hole 340 and the second detection hole 350 correspond to the first shaft hole 110 and the second shaft hole 120 respectively, and the fixed shaft 330 is arranged in the middle of the same end of the first fixing seat 310 and the second fixing seat 320; and a shaft 400, which is movably arranged in the first fixing seat 310 and the second fixing seat 320, and the shaft 400 is respectively connected with the first detection hole 340 and the second detection hole 350.

[0030] When the transmission cover 100 needs to be inspected, the transmission cover 100 is placed on the base plate 200, so that the transmission cover 100 is covered with the first fixing seat 310 and the second fixing seat 320, and the first shaft hole 110 and the second shaft hole 120 correspond to the first detection hole 340 and the second detection hole 350 respectively, and the positioning column 210 is inserted into the third shaft hole 130. At this time, if the shaft rod 400 can be smoothly inserted into the first shaft hole 110, the first detection hole 340, and the second detection hole 350 in sequence and extended into the second shaft hole 120, then the transmission cover 100 meets the production requirements; otherwise, the transmission cover 100 does not meet the production requirements. The transmission cover 100 comprehensive inspection fixture of the embodiment of the present application can quickly test the position and depth of each key hole on the transmission cover 100, facilitate the operation of on-site operators, ensure the detection accuracy and precision of the position, improve the on-site detection speed and detection efficiency, and solve the problem of slow three-coordinate detection rhythm and affecting the efficiency of the assembly line.
