[0003] These instruments and meters have various types and functions, but they all have a common feature: when being repaired, the instruments and meters need to be stably and accurately clamped and fixed. However, in practical applications, the existing instrument clamping devices have limitations and a narrow adaptation range. They are usually designed to clamp a specific size or type of instrument, resulting in the need to use different clamping mechanisms for different sizes and shapes of instruments. This not only increases the operation difficulty for users, but also increases the purchase and maintenance costs and reduces the work efficiency. Content of the Utility Model

A plurality of groups of driving sprockets are arranged on the output shaft of the driving motor. On one side of the fixed frame close to the right clamping mechanism, driven sprockets with the same number as the driving sprockets are arranged. Chains are arranged between the driving sprockets and the driven sprockets in the same vertical plane. A moving plate is fixedly arranged on the chains. The left clamping mechanism is arranged on the moving plate.

[0008] Further, second chutes are arranged on the side walls of the limiting grooves. On one side of the clamping rod, a sliding plate matching the second chutes is arranged.

[0009] Further, a stop block is arranged on one side of the sliding plate. The stop block is arranged in the second chutes.

[0010] Further, a servo motor is arranged on the fixed plate. A driving gear is arranged on the output shaft of the servo motor. The driving gear meshes with the driven gear.

Detailed Description of the Preferred Embodiment

[0024] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a clamping device for automated instrument maintenance according to the present utility model with reference to the drawings.

[0025] As Figures 1 to 5 shown, a clamping device for automated instrument maintenance includes a support frame 1. A moving mechanism 2 is provided on the left side of the top of the support frame 1. A left clamping mechanism 3 is provided on the moving mechanism 2. A right clamping mechanism 4 opposite to the left clamping mechanism 3 is provided on the right side of the top of the support frame 1. The moving mechanism 2 controls the left clamping mechanism 3 to approach or move away from the right clamping mechanism 4. The left clamping mechanism 3 and the right clamping mechanism 4 cooperate with each other to clamp the instrument body 101. The left end 102 and the right end 103 are respectively provided on the left and right sides of the instrument body 101. The left clamping mechanism 3 clamps the left end 102 of the instrument body 101, and the right clamping mechanism 4 clamps the right end 103 of the instrument body 101.

[0026] The left clamping mechanism 3 can be driven by the moving mechanism 2 to approach or move away from the right clamping mechanism 4, changing the distance between the left clamping mechanism 3 and the right clamping mechanism 4, so that the clamping device can be well adapted to clamp the instrument body 101 of different lengths, meeting the needs of the staff.

[0027] Both the left clamping mechanism 3 and the right clamping mechanism 4 include a fixing plate 301. A number of limiting grooves 302 are uniformly arranged on the side surface of the fixing plate 301. A clamping rod 311 sliding along the limiting groove 302 is arranged in the limiting groove 302. A second sliding groove 303 is arranged on the side wall of the limiting groove 302. A sliding plate 304 matching the second sliding groove 303 is arranged on the side wall of the clamping rod 311. The sliding plate 304 can slide in the second sliding groove 303. The sliding plate 304 cooperates with the second sliding groove 303 to prevent the clamping rod 311 from disengaging from the limiting groove 302, ensuring that the clamping rod 311 can smoothly slide in the limiting groove 302, improving the sliding stability of the clamping rod 311. A stop block 305 is arranged on one side of the sliding plate 304. The stop block 305 is arranged in the second sliding groove 303. The total thickness of the sliding plate 304 and the stop block 305 matches the depth of the second sliding groove 303. A limiting plate is arranged at the end of the second sliding groove 303 in the limiting groove 302. When the clamping rod 311 moves, the limiting plate can block the stop block 305 to prevent the clamping rod 311 from moving too far and disengaging from the limiting groove 302.

[0028] The circumferential surface of the fixing plate 301 is rotatably connected with a passive gear 307 through a bearing. A number of arc-shaped grooves 308 are uniformly formed through the passive gear 307. The number of the arc-shaped grooves 308 is the same as that of the clamping rods 311. A sliding rod 306 is arranged at one end of the clamping rod 311. The sliding rod 306 is located inside the arc-shaped groove 308.

[0029] A servo motor 310 is installed outside the fixing plate 301. A driving gear 309 is also rotatably connected to the fixing plate 301. The driving gear 309 is fixedly connected to the output end of the servo motor 310, and the driving gear 309 meshes with the passive gear 307.

[0030] The principles of the left clamping mechanism 3 and the right clamping mechanism 4 are as follows: The output end of the servo motor 310 drives the driving gear 309 to rotate, causing the passive gear 307 to rotate. Under the cooperation of the arc-shaped groove 308 and the sliding rod 306, a number of clamping rods 311 move closer to or away from the center position. When the clamping rods 311 approach the center, the left end 102 and the right end 103 of the instrument body 101 can be clamped; when the clamping rods 311 move away from the center, the clamping is released, which is convenient and fast.

[0031] The moving mechanism 2 is provided with a fixed frame 208 on the support frame 1. A driving motor 206 is arranged on the fixed frame 208. A plurality of groups of driving sprockets 201 are arranged on the output shaft of the driving motor 206. The driving sprockets 201 are arranged side by side. On the side of the fixed frame 208 close to the right clamping mechanism 4, driven sprockets 202 with the same number as the driving sprockets 201 are arranged. A chain 203 is arranged between the driving sprocket 201 and the driven sprocket 202 in the same vertical plane. A moving plate 204 is fixedly arranged on the chain 203. A left clamping mechanism 3 is arranged on the moving plate 204. The moving plate 204 is connected to the fixed plate 301 in the left clamping mechanism 3. The fixed plate 301 in the right clamping mechanism 4 is connected to the right side of the top of the support frame 1. The moving plate 204 is installed on a plurality of chains 203 arranged side by side. The chains 203 can share the gravity of the moving plate 204 and the left clamping mechanism 3, and enable the left clamping mechanism 3 to move smoothly, increasing the stability of the left clamping mechanism 3.

[0032] On both sides of the moving plate 204 inside the fixed frame 208, first chutes 207 are arranged. The moving plate 204 can move in the first chutes 207. Two groups of baffles 205 are arranged between the driving sprocket 201 and the driven sprocket 202. Through grooves for the chain 203 to pass through are arranged through the baffles 205. One of the baffles 205 is close to the driving sprocket 201, and the other is close to the driven sprocket 202. There is a certain distance between the two baffles 205. The two baffles 205 can limit the movement of the moving plate 204, so that the moving plate 204 always moves between the two baffles 205, preventing the chain 203 from moving too far and causing the moving plate 204 on the chain 203 to move below the chain 203.

[0033] When the utility model is in use, the left clamping mechanism 3 and the right clamping mechanism 4 can respectively clamp the left end 102 and the right end 103 on the instrument body 101, which is convenient and fast. Secondly, the moving mechanism 2 can drive the left clamping mechanism 3 to approach or move away from the right clamping mechanism 4, changing the distance between the left clamping mechanism 3 and the right clamping mechanism 4, so that the clamping device is well applicable to clamping instrument bodies 101 of different lengths, meeting the needs of users, and also improving the maintenance efficiency, thereby improving the practicability of the clamping device.
