A micro motor 209 is installed, and a deflection cam 210 is fixedly installed on the output shafts of the two micro motors 209 respectively. Two limiting blocks 207 are slidably installed on the two first sliding frames 211 respectively. The four limiting blocks 207 are respectively in contact and connected with the two micro motors 209.

The first sliding frames 211 are fixedly installed on the two sliding racks 212 respectively, and the two first sliding frames 211 are respectively slidably installed in the sliding groove of the support plate 102.

[0029] The two first sliding frames 211 are respectively fixedly installed with a limiting ring 202, and the two limiting rings 202 are respectively slidably installed with four second sliding frames 220, and the second sliding frames 220 are respectively fixedly installed with a clamping plate 221 and a second spring 222, one end of the second spring 222 is fixedly installed with the limiting ring 202, and the other end is fixedly installed with the second sliding frame 220, and the four second sliding frames 220 are slidably sleeved with a rotating ring 201, and the two rotating rings 201 are respectively provided with arc-shaped racks, and the two rotating rings 201 are respectively fixedly installed with two arc-shaped ratchet bars 223, and the four arc-shaped ratchet bars 223 are respectively matched with the ratchet bars of the four limiting blocks 207, and the two fourth brackets 106 are respectively fixedly installed with threaded shafts 219, and the two screw shafts 219 are respectively fixedly installed with the ...

A second motor 213 is fixedly installed on the support plate 105, and the output shaft of the second motor 213 is fixedly installed on the threaded shaft 219 close to the support plate 105.

[0030] During operation, the valve body 108 is placed in the limiting rings 202 on both sides respectively. At this time, the second gear 216 is meshed with the rack on the rotating ring 201, and the second motor 213 is started, thereby driving the threaded shaft 219 to rotate. Under the action of the thread, the sliding sleeve 214 drives the limiting plate 218 to move. At the same time, the rotation of the threaded shaft 219 drives the rotating shaft 215 to rotate, thereby driving the second gear 216 to rotate, and at the same time drives the threaded shaft 219 on the other side to rotate, thereby driving the limiting plates 218 on both sides to move relatively. When the second gear 216 rotates, it drives the rotating ring 201 to rotate. When the rotating ring 201 rotates, the arc-shaped ratchet bar 223 cooperates with the limiting block 207 to prevent the rotating ring 201 from reversing. When the rotating ring 201 rotates, the inner ring presses the second sliding frame 220 to move toward the center, thereby driving the clamping plate 221 to move toward the center, thereby making the clamping plate 221 clamp the valve body 108, thereby completing the centering and clamping of the valve body 108.

The first gear 206 rotates and drives the two sliding racks 212 to move relative to each other, and then drives the two first sliding frames 211 to move relative to each other, and then drives the two valve bodies 108 to move relative to each other. When the two valve bodies 108 are fitted together, the valve core 107 is located in the middle, and the first motor 203 stops working. At this time, the third gear 217 is meshed with the rack of the rotating ring 201, and the electric cylinder 401 is started to drive the fastening processor 402 to move closer to the valve body 108. The installation of the valve body 108 is completed through the fastening processor 402. After the installation is completed, the micro motor 209 is started to drive the deflection cam 210 to rotate 90°, and the deflection cam 210 presses The limiting blocks 207 on both sides make the limiting blocks 207 release the restriction on the arc-shaped ratchet strip 223, and the second motor 213 starts, driving the threaded shaft 219 to reverse, thereby driving the sliding sleeve 214 away from the valve body 108, and at the same time the third gear 217 drives the rotating ring 201 to reverse, so that the inner ring of the rotating ring 201 no longer provides pressure to the second sliding frame 220, and the clamping plate 221 is reset and away from the valve body 108 through the second spring 222, and the first motor 203 is started again, driving the first gear 206 to reverse, thereby driving the first sliding frame 211 away from the installed valve body 108, and at the same time the rotation of the first motor 203 drives the conveying assembly 3 to work, and move the assembled valve core 107 and valve body 108 out, thereby completing the assembly and transfer of the valve core 107 and valve body 108.

[0032] The conveying assembly 3 includes a conveying bracket 301 fixedly mounted on the support plate 102, and two rotating rollers are rotatably mounted on the conveying bracket 301.

The bearing plate 303 is provided with a column for preventing the valve core 107 from closing. When the two valve bodies 108 are closed, the column is just located at the opening of the two valve bodies 108 to avoid inaccurate installation of the valve core 107. When working, the power output by the first motor 203 is passed The valve core 107 is moved to the middle of the two valve bodies 108 by the conveyor belt 302 and the supporting plate 303. After the assembly is completed, the conveyor belt 302 drives the supporting plate 303 to move the assembled valve core 107 and valve body 108 out, thereby completing the assembly of the valve core 107 and valve body 108.

[0033] The processing component 4 includes an electric cylinder 401 fixedly installed on the third bracket 104, and a fastening processor 402 is fixedly installed on the extended shaft of the electric cylinder 401; when working, after the two valve bodies 108 are fitted together by the loading component 2, the electric cylinder 401 is started to drive the fastening processor 402 to approach the valve body 108. After reaching the set position, the electric cylinder 401 stops working, and the fastening processor 402 is started to assemble the two valve bodies 108. After the assembly is completed, the electric cylinder 401 is started to drive the fastening processor 402 away from the assembled valve body 108, thereby completing the assembly work.

[0034] Embodiment 2:

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, the working principle of an auxiliary device for assembling a servo valve is as follows: when working, the valve core 107 and the valve body 108 to be assembled are placed in the preset position to complete the clamping, and the valve core 107 and the valve body 108 to be assembled are moved to the set position through the cooperation of the loading component 2 and the conveying component 3, and then the valve core 107 and the valve body 108 are assembled through the processing component 4, and then the assembled valve core 107 and the valve body 108 are moved out through the cooperation of the loading component 2 and the conveying component 3 to complete the assembly work.
