[0029] Combined with appendix Figures 1-4A clamping device for mechanical parts includes a support plate 1, an upper clamping device 2 and a lower clamping device 3. The mechanical parts are clamped between the upper clamping device 2 and the lower clamping device 3. Specifically, this device clamps the mechanical parts by the upper clamping device 2 and the lower clamping device 3, achieving bidirectional clamping, which makes the mechanical parts firm and reliable, and provides a guarantee for subsequent processes.

[0030] In specific implementation of this utility model, such as Figures 1-3 As shown, the upper clamping device 2 includes a bracket 201, an adjusting plate 202 hinged to the bracket 201, and a pressure block 203 mounted on the adjusting plate 202. The upper clamping device 2 also includes a telescopic rod 204 hinged to the bracket 201. A rocker arm 205 is hinged to the output end of the telescopic rod 204. The lower end of the rocker arm 205 is hinged to the bracket 201, and the rocker arm 205 can drive the adjusting plate 202 to rotate and adjust. Specifically, the outer shell of the telescopic rod 204 is hinged to the bracket 201. When the telescopic rod 204 is working, the telescopic end extends, driving the rocker arm 205 to rotate and make fine adjustments. The telescopic rod 204 is hinged to the bracket 201 and automatically adjusts the angle. When the rocker arm 205 rotates, it drives the adjusting plate 202 hinged to the bracket 201 to rotate, driving the pressure block 203 to approach the mechanical parts to complete the clamping.

[0031] In specific implementation of this utility model, such as Figures 1-4 As shown, the lower clamping device 3 includes a connecting block 301, an adjustable support block 302 mounted on the connecting block 301, a piston 305 mounted on the lower end of the support block 302 and located inside the connecting block 301, a guide tube 303 mounted opposite to the lower end of the support block 302 and penetrating the support plate 1, and an airbag 304 installed between the connecting block 301 and the support plate 1, with a through hole on the support plate 1 to facilitate movement of the guide tube 303. A piston chamber for use with the piston 305 is provided on the connecting block 301, and the airbag 304 is connected to the piston chamber via a pipe. Specifically, the piston 305 moves within the piston chamber, and the airbag 304, connected to the piston chamber via a pipe and located below the piston 305, is used to adjust pressure. When the airbag 304 is subjected to pressure from the connecting block 301, it pushes the piston 305 upward, causing the support block 302 to abut against the lower end of the mechanical component.

[0032] Specifically, the upper end of the piston 305 includes a connecting rod, and the support block 302 is mounted on the connecting rod. The movement of the piston 305 within the piston chamber is existing technology and will not be described again.

[0033] A connecting plate 4 is installed at the lower end of the two guide tubes 303. A spring 5 is installed on the outside of the guide tubes 303 and between the connecting plate 4 and the support plate 1. Specifically, the two guide tubes 303 limit the up and down movement of the connecting block 301, and the spring 5 performs secondary adjustment as the guide tubes 303 move within the through hole.

[0034] In a specific implementation of this utility model, a connecting block 6 is installed on the support plate 1, and the bracket 201 is fixed to the connecting block 6 by bolts.

[0035] The working principle of this utility model:

[0036] The mechanical parts are placed between the upper clamping device 2 and the lower clamping device 3. The telescopic rod 204 operates, extending its telescopic end, which drives the rocker arm 205 to rotate for fine adjustment. The telescopic rod 204 is hinged to the bracket 201 and automatically adjusts its angle. The rocker arm 205 rotates, driving the adjusting plate 202 hinged to the bracket 201 to rotate, which drives the pressure block 203 to approach the mechanical parts to complete the clamping. The mechanical parts are subjected to downward force, pushing the connecting block 301 to move. The connecting block 301 compresses the air bladder 304. When the air bladder 304 is subjected to the pressure of the connecting block 301, it pushes the piston 305 upward, causing the support block 302 to abut against the lower end of the mechanical parts. The guide tube 303 moves within the through hole, and the spring 5 performs secondary adjustment to complete the bidirectional clamping, making the mechanical parts firm and reliable, thus ensuring the subsequent processes.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
