[0040] In an embodiment of the present invention, the reverse gear housing 50 is placed on a clamping position on the panel 10, and then fixed on the clamping position by the clamping member 30 and the supporting member 40. The clamping member 30 provides a clamping force, and the supporting member 40 provides a supporting force to ensure the stability of the reverse gear housing 50 during processing and prevent displacement or vibration during processing.

The positioning column 41 and the positioning blocks 42 can ensure that the reverse gear housing 50 is stably fixed on the support member 40 to improve the stability and accuracy when processing the hole.

[0042] Based on the above scheme, Figure 2As shown, in the embodiment of the present invention, a locating pin 43 is provided on the locating block 42 for locating the mounting hole 54 on the bottom mounting seat 53 of the reverse gear housing 50. The locating pin 43 is inserted into the mounting hole 54 of the bottom mounting seat 53 of the reverse gear housing 50 to ensure that the reverse gear housing 50 will not shift in a fixed position, thereby improving the processing accuracy. At the same time, each time the reverse gear housing 50 is installed, the locating pin 43 can ensure that the housing is always in the same position, thereby improving the repeatability of the processing and reducing human errors.

When the telescopic end of the second driving member 31 is extended and retracted, the pull rod 33 is driven to move, and the movement of the pull rod 33 is transmitted to the clamping arm 34 through the rotating connection point, so that the clamping arm 34 rotates around the fixed rod 32, and the other end of the clamping arm 34 presses the reverse gear housing 50 on the positioning block 42 to ensure that the reverse gear housing 50 is firmly fixed in the clamping position to prevent displacement or vibration during the processing.

[0044] In an embodiment of the present invention, the first driving member 21 and the second driving member 31 both adopt linear mechanisms such as mature air cylinders, oil cylinders or electric cylinders in the prior art that can realize telescopic functions. No restrictions are made in the description of this implementation, and the first driving member 21 and the second driving member 31 can both be electrically connected to a conventional PLC controller or a single-chip microcomputer to realize automatic control.

[0045] Specifically, Figure 4 As shown, in the embodiment of the present invention, a bearing seat 22 is provided on the top of the base plate 20, and the bearing seat 22 is rotatably connected to the connecting shaft 11. The connecting shaft 11 is fixedly provided with a connecting seat 12, and the connecting seat 12 is arranged at the bottom of the panel 10.

When the first limit block 23 abuts against the telescopic end of the first buffer rod 25, the first limit block 23 limits the rotation angle of the panel 10 to prevent damage caused by excessive rotation. At the same time, the telescopic end of the first buffer rod 25 provides a buffering effect, reduces impact and vibration, and protects the tooling and the reverse gear housing 50, and the side of the first limit block 23 that contacts the first buffer rod 25 is an arc structure, which makes the contact between the first limit block 23 and the first buffer rod 25 smoother and more uniform, further reducing impact and vibration.
