Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Such as Figures 1-5As shown in the figure, an electric actuator multi-station testing machine includes a support mechanism 1, and fixing mechanisms 2 are arranged on both sides of the support mechanism 1. The fixing mechanism 2 includes a motor 202 and an electric telescopic rod 208. It also includes: The fixing mechanism 2 includes a rotating rod 201. Guide rails 204 are respectively fixedly connected to the upper and lower sides of the front surface of the rotating rod 201. The inner wall of the bottom end of the rotating rod 201 is fixedly installed with the motor 202, and the output shaft of the motor 202 is fixedly connected with a gear 203. Among them, moving blocks 205 are slidably connected to both sides of the guide rail 204. A screw rod 206 is rotatably connected to the surface of one moving block 205, and a sliding rod 207 is fixedly connected to the surface of the other moving block 205. Among them, an electric telescopic rod 208 is fixedly connected to the middle of one moving block 205, and the extending end of the electric telescopic rod 208 is fixedly connected to the other moving block 205, as Figure 3 shown, when the electric telescopic rod 208 starts and drives the piston end to extend, the two moving blocks 205 are pushed to move outward along the guide rail 204;

[0030] Threads are arranged on both the upper and lower sides of the screw rod 206, and the threads on both sides of the surface of the screw rod 206 face in opposite directions. Threaded sleeves 209 are also sleeved on the upper and lower sides of the outer wall of the screw rod 206. Sliding sleeves 210 are respectively slidably sleeved on the upper and lower sides of the outer wall of the sliding rod 207, as Figure 3 shown, when the screw rod 206 rotates, the threads on the upper and lower sides of the screw rod 206 respectively push the two threaded sleeves 209 to move in opposite directions;

[0031] A limit sleeve 211 is fixedly installed on the front surface of the threaded sleeve 209. A limit rod 212 is slidably sleeved on the inner wall of the limit sleeve 211. One end of the limit rod 212 extends to the outside of the limit sleeve 211, and the end of the limit rod 212 located outside the limit sleeve 211 is fixedly connected to the sliding sleeve 210, as Figure 3 shown, the length direction of the limit rod 212 is the same as the length direction of the screw rod 209, so that the lifting plates 213 in the same horizontal direction move simultaneously;

[0032] Lifting plates 213 are fixedly connected to both the end heads of the limit sleeve 211 and the limit rod 212. A positioning rod 214 is fixedly connected to the middle of the front surface of the lifting plate 213. A push rod 215 is penetrated and connected to the surface of the lifting plate 213 and inside the positioning rod 214. One end of the push rod 215 is fixedly connected to a push block 216. Two sides of the inner wall of the push block 216 are fixedly connected with a first spring 217. The other side of the first spring 217 is fixedly connected with a resisting block 218. The outer wall of the resisting block 218 is penetrated and connected with the positioning rod 214. And a second spring 219 is fixedly connected to the end of the push block 216 away from the push rod 215. The other side of the second spring 219 is fixedly connected to the inner wall of the positioning rod 214, as Figure 5As shown, the left side of the abutting block 213 is a straight surface, while the right side is an inclined surface. When the push rod 215 is pushed to the right, the inclined surface side of the abutting block 213 is squeezed by the positioning rod 214, so that the abutting block 218 compresses the first spring 217 and contracts into the inside of the positioning rod 214;

[0033] The support mechanism 1 includes a base 101. A support column 102 is rotatably connected to the middle of the top of the base 101. Both sides of the top of the support column 102 are fixedly connected with support rods 103. The ends of the support rods 103 away from the base 101 are rotatably connected to a rotating rod 201. The outer wall of the support column 102 and below the two support rods 103 are fixedly connected with arc-shaped rails 104. The lower end of the inner side of the arc-shaped rail 104 is fixedly connected with an annular rack 105. The outer wall of the gear 203 is meshed with the annular rack 105, and the side of the gear 203 abuts against the arc-shaped rail 104. As Figure 2 shown, when the gear 203 rotates, the convex teeth on the side of the gear 203 push the annular rack 105, and then the gear 203 drives the lower end of the rotating rod 201 to move along the inner side of the arc-shaped rail 104.

[0034] The working principle of the present invention:

[0035] When the device is in use, according to the distance between the connection holes on the surface of the electric actuator to be tested, the distance between the lifting plates 213 is adjusted. That is, by starting the electric telescopic rod 208 to drive the piston end to extend, the two moving blocks 205 move along the length direction of the guide rail 204, so as to adjust the distance between the lifting plates 213 in the horizontal direction. By rotating the screw rod 206, the nut sleeve 209 is driven to move along the screw rod 206 direction. Then, through the mutual connection between the limit sleeve 211 and the limit rod 212, the distance between the lifting plates 213 in the vertical direction is adjusted;

[0036] Secondly, when installing the electric actuator, the connection hole is sleeved on the surface side of the positioning rod 214, and the electric actuator is pushed to abut against the surface of the lifting plate 213. During this period, the inner side of the connection hole of the electric actuator pushes the inclined surface side of the abutting block 218, so that the abutting block 218 contracts into the inside of the push block 216. When the electric actuator is separated from the abutting block 218, the first spring 217 pushes the abutting block 218 to lift and reset. At this time, the abutting block 218 cooperates with the lifting plate 213 to clamp and fix the electric actuator.

[0037] The above has described a detailed description of an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
