[0024] The gas meter housing 10 to which the device is applicable includes an eaves body 11 arranged at the top and an arc-shaped side wall 12 below the eaves body 11 .

[0025] Specifically, the arc-shaped side walls 12 are located on the left and right sides of the watch case 10 .

[0026] like Figure 3 、 Figure 4 、 Figure 5 As shown, Figure 3 Shown is a schematic diagram of a gripping device in an embodiment; Figure 4 Shown is a schematic diagram of the cooperation between the watch case and the gripping device in the embodiment; Figure 5 Shown is a three-dimensional schematic diagram of the clamping member;

[0027] The device includes:

[0028] Main frame 21;

[0029] The clamping member 30 is symmetrically arranged and movably arranged on both sides of the main frame 21; the clamping member 30 includes a flexible clamping block 33, and the flexible clamping block 33 includes a first clamping portion 331 arranged in front and back and a second clamping portion 332 in the middle. The second clamping portion 332 matches the shape of the arc-shaped side wall 12;

[0030] Clamping state: the symmetrically arranged clamping members 30 are close to each other, the clamping parts 331 on both sides extend under the eaves 11 at the front and rear ends of the side case 10, and the clamping parts 332 are in contact with the curved side wall 12.

[0031] The main frame 21 can be installed at the movable end of the robotic arm. After the device clamps the watch case 10, the robotic arm moves the device and the watch case 10 to the desired position to achieve grasping.

[0032] The movable clamping parts 30 can move closer to or farther away from each other in the horizontal direction. Specifically, the clamping part 1 331 extends into the bottom of the eaves 11 at the four corners of the case 10 to clamp and lift it upward to achieve the grasping action. The clamping part 2 332 is arranged to fit with the curved side wall 12, thereby further cooperating with the clamping part 1 331 to achieve stable grasping.

[0033] The flexible clamping block 33 can be made of rubber material. Through the provision of the flexible clamping block 33, when grabbing the watch case 10, it can be deformed to fit the irregular shape of the watch case 10, thereby ensuring a high degree of fit with the watch case 10 when grabbing; and when fitting with the watch case 10, it can increase the friction between the watch case 10 and the watch case 10, thereby ensuring the accuracy and stability of the grabbing position; in addition, the flexible clamping block 33 can also reduce damage or indentations to the surface of the watch case 10.

[0034] like Figure 3 、 Figure 4 、 Figure 5 As shown, Figure 3 Shown is a schematic diagram of a gripping device in an embodiment; Figure 4 Shown is a schematic diagram of the cooperation between the watch case and the gripping device in the embodiment; Figure 5 Shown is a three-dimensional schematic diagram of the clamping member;

[0035] It also includes a fixing box 22, which is arranged at the bottom end of the main frame 21;

[0036] The movable plate 23 is movably arranged on both sides of the fixed box 22, and the clamping member 30 is detachably installed at one end of the movable plate 23 away from each other. A driving member 41 is provided inside the fixed box 22, and output shafts are provided at opposite ends of the driving member 41. The output shafts pass through the fixed box 22 and are connected to the movable plate 23 on the side. The driving member 41 drives the two movable plates 23 to move closer to or away from each other.

[0037] The driving member 41 can be a double-headed cylinder in the prior art, that is, the piston rods (output shafts) at both ends can move synchronously. The driving member 41 is set to drive the movable plates 23 on both sides to move, so that the movable plates 23 can approach or move away from each other, thereby driving the clamping members 30 detachably connected to them to approach or move away from each other.

[0038] A guide groove 42 is further provided on the top of the fixed box 22 , and a guide rod 43 is further provided on one end of the two movable plates 23 close to each other. The guide rod 43 is movably inserted in the guide groove 42 .

[0039] The guide groove 42 is arranged in the horizontal direction. When the movable plate 23 moves, the guide rod 43 moves in the guide groove 42 to play a guiding role to ensure the position stability of the movable plate 23 and the clamping member 30 during the movement.

[0040] Within the movable range of the output shaft of the driving member 41 , the guide rod 43 will not escape from the guide groove 42 .

[0041] The clamping member 30 also includes a mounting plate 1 31 and a mounting plate 2 32. The mounting plate 1 31 is detachably connected to the movable plate 23. The flexible clamping block 33 is arranged on one end of the two mounting plates 2 32 close to each other. A mounting hole 1 311 is provided on the mounting plate 1 31, and a mounting hole 2 is provided on the movable plate 23 at a position corresponding to the mounting hole 1 311. Bolts 34 are movably inserted in the mounting hole 1 311 and the mounting hole 2, and nuts are installed to lock the mounting plate 1 31 and the movable plate 23.

[0042] Specifically, there are two mounting holes 1 311 and two mounting holes on each side. Through the provided mounting holes 1 311 , mounting holes 2 , bolts 34 and nuts, a detachable connection between the mounting plate 1 31 and the movable plate 23 , that is, a detachable connection of the clamping member 30 , is achieved.

[0043] The detachable clamping member 30 can be easily disassembled, replaced or maintained, thereby improving the flexibility of the device.

[0044] Working principle: When the device is in use, the robot arm is used to move the device to the position corresponding to the watch case 10, and then the driving member 41 is started. The driving member 41 drives the movable plates 23 on both sides to approach each other, that is, drives the clamping members 30 on both sides to approach each other, until the clamping parts 331 on both sides are extended under the eaves 11 on the front and rear sides of the watch case 10 on the side where they are located, and the clamping part 332 is in contact with the curved side wall 12 on the side where they are located. After the device clamps the watch case 10, the robot arm is used to move the device and the watch case 10 to the desired position to achieve the grasping of the watch case 10.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
