The piston cylinder 6 is located in the middle and at the bottom of the mounting base 1.

[0028] The self-locking horizontal clamping mechanism provided in this application is highly targeted and can achieve horizontal clamping of processed body parts, preventing horizontal runout and improving processing accuracy. In particular, it successfully solves the problem of unstable actual clamping force output of cylinders due to large fluctuations in external air pressure or large reaction forces. Furthermore, the mechanism is smaller in size, reducing costs. This mechanism has broad application prospects and is suitable for widespread application.

[0029] In another embodiment of the present invention, the clamping block 4 of the self-locking horizontal clamping mechanism is detachably connected to the movable arm 3 so as to facilitate the replacement of different clamping blocks 4.

[0030] In another embodiment of the present invention, the bottom of the mounting base 1 of the self-locking horizontal clamping mechanism is provided with mounting holes 11 for fixing the mounting base 1, and the mounting base 1 is fixedly connected to the external device through the mounting holes 11.

[0031] In another embodiment of the present invention, the movable arm 3 of the self-locking horizontal clamping mechanism is provided with a flat part at one end of the connecting rod module 2, and a groove matching the flat part is provided at one end of the connecting rod module 2 near the movable arm 3.

[0032] In another embodiment of the present invention, the front end of the movable arm 3 of the self-locking horizontal clamping mechanism is provided with a plurality of fixing holes 31 that match the clamping block 4.

[0034] The working principle of the clamping mechanism provided in this application is as follows:

[0035] As shown in the figure, in use, this utility model is first fixed to one side of the workpiece via the mounting base 1. The piston cylinder 6 pushes upward, causing the connecting rod module 2 and the connecting plate 5 to rotate clockwise and counterclockwise towards the mounting base 1 respectively. Simultaneously, this drives the movable arm 3 to move horizontally, thereby pressing the workpiece with the clamping block 4 at the front end of the movable arm 3. When the clamping cylinder reaches a certain stroke, the connecting rod module 2, movable arm 3, and connecting plate 5 reach a dead point position, achieving a self-locking function. This ensures horizontal clamping of the workpiece, preventing horizontal runout and improving machining accuracy. When releasing the workpiece, the piston rod 8 of the piston cylinder 6 retracts, pulling the connecting rod module 2 and connecting plate 5 to rotate clockwise and counterclockwise simultaneously. At the same time, the connecting rod module 2 drives the movable arm 3 to move horizontally via a hinge, thus releasing the workpiece. It is understood that the clamping block 4 is detachably connected to the movable arm 3. By changing the clamping block 4, different workpieces can be clamped. For different workpieces, only the corresponding clamping block 4 needs to be matched, achieving the effect of saving space and cost.

[0036] The self-locking horizontal clamping mechanism provided in this application is highly targeted and can achieve horizontal clamping of processed body parts, preventing horizontal runout and improving processing accuracy. In particular, it successfully solves the problem of unstable actual clamping force output of cylinders due to large fluctuations in external air pressure or large reaction forces. Furthermore, the mechanism is smaller in size, reducing costs. This mechanism has broad application prospects and is suitable for widespread application.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
