[0022] Please refer to Figures 1-4 The present application provides a special fixture for finish machining of an actuator end cover, which comprises a base 1 and a positioning table 2 arranged on the upper surface of the base 1. The positioning table 2 is symmetrically provided with adjusting frames 3 on both sides. An air cylinder 33 is arranged at the middle position of the upper surface of each adjusting frame 3. An adjusting groove 31 is formed in the inner side of each adjusting frame 3. A lifting plate 32 is slidably arranged in the adjusting groove 31. A mounting plate 4 is connected to one side of the lifting plate 32. An adjusting plate 41 is slidably arranged on one side of the mounting plate 4. A clamping plate 42 is connected to one side of the adjusting plate 41. The arrangement can make the lifting plate 32 lift to adjust the height of the clamping plate 42 by the working of the air cylinder 33. The position of the clamping plate 42 can be adjusted by moving the adjusting plate 41 in the mounting plate 4 to clamp and position the actuator end cover on the positioning table 2, thereby ensuring the stability of the actuator end cover.

[0023] For example Figure 2As shown in the figure, the upper surface of the lifting plate 32 is provided with a connecting sleeve 322 in the middle position, and the telescopic end of the air cylinder 33 is embedded in the inside of the connecting sleeve 322 and connected by screws. The inside of the adjusting groove 31 is also provided with a guide rod 34 symmetrically, and the lifting plate 32 is slidingly arranged outside the guide rod 34. The arrangement utilizes the work of the air cylinder 33 to make the lifting plate 32 lift in the inside of the adjusting groove 31, so as to adjust the height of the clamping plate 42 to facilitate the purpose of clamping and positioning the actuator end cover.

[0024] As shown in the figure, Figure 2 and Figure 3 As shown in the figure, one side of the mounting plate 4 is provided with a positioning rod 43 symmetrically, and the position close to the mounting plate 4 of one side of the lifting plate 32 is provided with a positioning hole 321 matched with the positioning rod 43. The arrangement utilizes the positioning rod 43 embedded in the inside of the positioning hole 321 to realize the positioning installation of the mounting plate 4.

[0025] As shown in the figure, Figure 2 and Figure 4 As shown in the figure, the upper surface of the lifting plate 32 is also provided with a bolt symmetrically, and the upper surface of the positioning rod 43 is provided with a mounting hole. The end of the bolt is embedded in the inside of the mounting hole and is screwed with the mounting hole. The arrangement utilizes the threaded connection of the bolt and the mounting hole to ensure the stability of the installation of the mounting plate 4 and the lifting plate 32.

[0026] As shown in the figure, Figure 4 As shown in the figure, one side of the adjusting plate 41 is connected with a limiting plate 411 in the inside of the mounting plate 4, and the inside of the mounting plate 4 is provided with an electric push rod 44.
