DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1-4 As shown, a push-type automatic clamping device comprises a housing 1 and a baffle 2 connected to each other, two clamping assemblies symmetrically arranged with the midpoint of the baffle 2, and a power assembly for pushing the two clamping assemblies to move toward and away from each other;

[0026] The clamping assembly includes a clamping claw seat 4 slidably connected to the baffle 2, and a clamping claw 5 detachably connected to the clamping claw seat 4;

[0027] The power assembly includes a transmission member and a servo motor 8 for driving the transmission member to operate, and the transmission member is a gear transmission member.

[0028] Preferably, the clamping jaw seat 4 includes a connecting portion 41 and a sliding groove 42 provided on the connecting portion 41;

[0029] The housing 1 is symmetrically provided with two slide rails 3 with the baffle 2 as the central axis, and the slide groove 42 is slidably connected to the slide rails 3 .

[0030] Preferably, the clamping jaw 5 comprises a second connection portion 51 detachably connected to the first connection portion 41 , and a clamping portion 52 connected to the second connection portion 51 . The two clamping portions 52 are arranged corresponding to each other and are both provided with a clamping groove 53 .

[0031] It should be noted that, in this embodiment, the shape of the clamping groove 53 is designed according to the shape of the clamped object, so as to better fit the clamped object.

[0032] Preferably, the gear transmission member includes a rotating shaft 61 connected to the output shaft of the servo motor 8, a gear 62 fixed on the rotating shaft 61, and two toothed plates 63 respectively provided on the two clamping jaw seats 4 and meshing with the gear 62.

[0033] It should be noted that, in this embodiment, the rotating shaft 61 is rotatably connected to the housing 1 and the baffle 2 via a bearing.

[0034] When it is necessary to clamp the clamped object, the servo motor 8 drives the rotating shaft 61 to rotate, and the rotation of the rotating shaft 61 will drive the gear 62 to rotate. The rotation of the gear 62 will drive the two tooth plates 63 to move toward each other, thereby driving the two clamping claw seats 4 and the two clamping claws 5 to move toward each other, so that the clamped object is clamped by the two clamping parts 52. The two clamping parts 52 are squeezed against each other, and the clamping force and stability are good. When it is necessary to place the clamped object, the servo motor 8 drives the two tooth plates 63 to move away from each other to release the clamped object.

[0035] Preferably, a camera bracket 9 is detachably connected to the top of the shell 1, and a camera 10 is detachably connected to the camera bracket 9. The camera 10 is installed on the top of the shell 1 through the camera bracket 9, and the position of the clamped object can be photographed through the camera 10.

[0036] Example 2

[0037] like Figure 5 As shown, a push-type automatic clamping device is different from Example 1 in that, in this embodiment, the power assembly includes a transmission member and a servo motor 8 for driving the transmission member to operate, and the transmission member is a chain transmission member.

[0038] Preferably, the chain transmission member includes two rotating shafts 71, two sprockets 72 respectively fixed on the two rotating shafts 71, a chain 73 arranged between the two sprockets 72, and two connecting seats 74 respectively arranged on the two clamping jaw seats 4, the two connecting seats 74 are respectively fixedly connected to the two parallel sections of the chain 73, and one of the rotating shafts 71 is connected to the output shaft of the servo motor 8.

[0039] It should be noted that, in this embodiment, the two second rotating shafts 71 are both rotatably connected to the housing 1 and the baffle 2 via bearings.

[0040] When it is necessary to clamp the clamped object, one of the rotating shafts 71 is driven to rotate by the servo motor 8, and the sprocket 72 on the rotating shaft 71 rotates together with the rotating shaft 71, thereby driving the chain 73 to transmit, and the other rotating shaft 71 and the sprocket 72 are driven to rotate together through the chain 73 transmission. In the process of chain 73 transmission, the two connecting seats 74 on the two parallel sections of the chain 73 are driven to move toward each other, thereby driving the two clamping claw seats 4 and the two clamping claws 5 to move toward each other, so that the clamped object is clamped by the two clamping parts 52. The two clamping parts 52 are squeezed against each other, and the clamping force and stability are both good. When it is necessary to place the clamped object, the servo motor 8 drives the two connecting seats 74 to move away from each other to release the clamped object.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
