Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example:

[0022] The present invention provides a high-precision assembly device for an actuator. The pneumatic head housing clamping mechanism and the pneumatic head spring pressing mechanism are designed to achieve automatic positioning and automatic compression of the pneumatic head housing and the pneumatic head spring, which is more labor-saving and convenient to operate, thereby greatly improving the assembly accuracy and assembly efficiency of the pneumatic actuator, and effectively improving the operating stability and automation level of the pneumatic actuator, thereby solving the problems raised in the above-mentioned background technology.

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] The high-precision assembly device for the actuator includes a pneumatic head housing clamping mechanism 1 and a pneumatic head spring pressing mechanism 2. The design of the pneumatic head housing clamping mechanism 1 and the pneumatic head spring pressing mechanism 2 can realize automatic positioning and automatic compression of the pneumatic head housing and the pneumatic head spring, which is more labor-saving and convenient to operate, thereby greatly improving the assembly accuracy and assembly efficiency of the pneumatic actuator, and effectively improving the operating stability and automation level of the pneumatic actuator. The pneumatic head housing clamping mechanism 1 includes a base 11, and a fixed claw 12 is fixedly installed at one end of the top surface of the base 11. The end of the top surface of the base 11 away from the fixed claw 12 is driven by a screw drive assembly 13 A movable claw 14 is movably installed, and claw teeth 15 are fixedly installed at both ends of the top surface of the fixed claw 12 and the movable claw 14. The claw teeth 15 are provided with a tooth groove 16 adapted thereto on the side close to the pneumatic head housing, and the design of the tooth groove 16 adapted to the pneumatic head housing is more conducive to the stability of the pneumatic head housing during assembly, while reducing mechanical damage to the pneumatic head housing, which is beneficial to product quality. At the same time, claw teeth 15 are fixedly installed at both ends of the top surface of the fixed claw 12 and the movable claw 14, which can effectively avoid covering the air port and screw fasteners on the pneumatic head housing, thereby facilitating testing and debugging of the external air source of the pneumatic head housing during assembly;

[0025] Among them, the screw transmission assembly 13 includes a screw body 131, a stepper motor 132 and a limit slide 133. The screw body 131 is installed through the center of the movable claw 14. The output shaft of the stepper motor 132 and one end of the screw body 131 are fixedly connected through a coupling. The stepper motor 132 is fixedly installed on the top surface of the base 11 away from the side of the fixed claw 12 through the motor seat 1321. The limit slide 133 is installed through the movable claw 14 near both ends. One end of the limit slide 133 is fixed to the fixed claw 12. The claw 12 is fixedly connected, and the end of the limiting slide 133 away from the fixed claw 12 is fixedly installed on the top surface of the base 11 through the end seat 1331. When positioning, the pneumatic head housing to be assembled can be placed between the fixed claw 12 and the movable claw 14. Under the action of the stepping motor 132, the screw body 131 starts to rotate and drives the movable claw 14 to move in the direction close to the fixed claw 12 until the fixed claw 12 and the movable claw 14 clamp the pneumatic head housing in position, thereby preventing the pneumatic head housing from being displaced during the assembly process;

[0026] The pneumatic head spring press-fitting mechanism 2 is composed of a first end press-fitting assembly 3 and a second end press-fitting assembly 4 which are symmetrically distributed on both sides of the pneumatic head housing clamping mechanism 1. The design of the first end press-fitting assembly 3 and the second end press-fitting assembly 4 can realize simultaneous press-fitting of the springs at both ends of the pneumatic head housing, further improving the accuracy and efficiency of the overall assembly.

[0027] Among them, the first end head press-fitting assembly 3 and the second end head press-fitting assembly 4 both include a fixed seat 5, the top surface of the fixed seat 5 is fixedly installed with a side mounting frame 51 at one end away from the pneumatic head housing clamping mechanism 1, the fixed seat 5 is fixedly connected to the base 11 at one end away from the side mounting frame 51, the fixed seat 5 and the side mounting frame 51 are L-shaped, the top of the side mounting frame 51 is arc-shaped, and the side mounting frame 51 is movably installed with a pneumatic head end cover fixture 53 on one side of the side mounting frame 51 close to the pneumatic head housing clamping mechanism 1 through an electric telescopic rod 52, and the interior of the pneumatic head end cover fixture 53 is embedded with a pneumatic head housing suitable for placing After the pneumatic head housing is fixed with the pneumatic head end cover 54 with a spring, the pneumatic head end cover 54 with a spring to be assembled can be embedded and installed inside the pneumatic head end cover fixture 53. Then, under the action of the electric telescopic rod 52, the pneumatic head end cover fixture 53 is continuously displaced toward the pneumatic head housing until the spring is compressed between the piston and the end cover, and the end cover fits tightly with the housing. At this time, the end cover and the housing can be fixed by the firmware. After the fixation is completed, the pneumatic head end cover fixture 53 automatically resets, and there is no need for manpower to compress the pneumatic spring.

[0028] In addition, in this embodiment, please refer to Figure 5 , the pneumatic head end cover clamp 53 is fixedly installed with several groups of L-shaped clamping jaws 531 distributed in an annular manner around the outer surface of the pneumatic head end cover 54 with a spring, and an anti-obstruction groove 532 is opened on the inner wall of any group of the several groups of L-shaped clamping jaws 531 near one end of the pneumatic head shell. The design of the several groups of L-shaped clamping jaws 531 distributed in an annular manner can effectively prevent the obstruction of the fixation of the pneumatic head shell and the end cover, which is more convenient to operate, and has a greater clamping force on the pneumatic head end cover 54 with a spring, which is more conducive to press-fitting. At the same time, the design of the anti-obstruction groove 532 can make the thickness of the L-shaped clamping jaw 531 near the pneumatic head shell slightly smaller than the thickness near the end cover, thereby ensuring the stability of the pneumatic head end cover 54 with a spring, making it more conducive to the smoothness of press-fitting and reducing resistance.

[0029] It should be noted that the stepper motor and the electric telescopic rod are both existing technologies and will not be described in detail here.

[0030] In this embodiment, the implementation scenario is specifically as follows: during assembly, the pneumatic head housing to be assembled can be placed between the fixed claw 12 and the movable claw 14. Under the action of the stepping motor 132, the screw body 131 starts to rotate and drives the movable claw 14 to move in the direction close to the fixed claw 12 until the fixed claw 12 and the movable claw 14 clamp and position the pneumatic head housing to prevent the pneumatic head housing from being displaced during the assembly process. After the pneumatic head housing is fixed, the pneumatic head end cover 54 with a spring to be assembled can be embedded and installed in the pneumatic head end cover fixture 5. 3, and then under the action of the electric telescopic rod 52, the pneumatic head end cover clamp 53 continuously moves toward the pneumatic head shell until the spring is compressed between the piston and the end cover, and the end cover is tightly fitted with the shell. At this time, the end cover and the shell can be fixed by firmware. After the fixation is completed, the pneumatic head end cover clamp 53 automatically resets, and there is no need for manpower to compress the pneumatic spring, which is more labor-saving and convenient to operate, thereby greatly improving the assembly accuracy and assembly efficiency of the pneumatic actuator, and effectively improving the operating stability and automation level of the pneumatic actuator.
