[0031] The clamping component 5 is disposed on the outer surface of the connecting block 21, and the clamping component 5 includes a gripper 51, a sliding groove 52 and an anti-slip block 53.

[0032] The function of the connecting component 2 is to connect and limit, and the function of the driving component 4 is to realize the rotation of the clamping component 5 through extension and retraction. The function of the clamping component 5 is to clamp and fix the workpiece 3 by rotating.

[0033] The connecting block 21 is fixedly installed inside the movable base 1, and the connecting groove 22 is formed inside the connecting block 21.

[0034] The bottom of the connecting block 21 is cylindrical and the top is inverted conical. The two ends of the top are connected by bolt threads to fix the connecting block 21 inside the movable seat 1. The two ends of the processed part 3 are connected to two cylindrical blocks, which are respectively embedded in the connecting grooves 22 inside the two connecting blocks 21, so as to limit the two ends of the processed part 3.

[0035] The cylinder telescopic rod 41 is fixedly installed on the outer surface of the movable seat 1, and the support rod 42 is fixedly connected to the top of the cylinder telescopic rod 41.

[0036] There are four cylinder telescopic rods 41, which are fixedly installed at the four corners of the movable seat 1. The tops of two cylinder telescopic rods 41 that are on the same horizontal line are fixedly connected by a rod 42. When the four cylinder telescopic rods 41 extend or retract, they can drive the two rods 42 to move up and down synchronously.

[0037] One end of the gripper 51 is movably connected to both ends of the connecting block 21, the slide groove 52 is formed on the surface of the gripper 51, the support rod 42 is movably embedded in the interior of the slide groove 52, the anti-slip block 53 is fixedly installed on the other end of the gripper 51, and the anti-slip block 53 is fixedly connected to the surface of the workpiece 3.

Under the pressure, the two jaws 51 rotate with the connection point at both ends of the connecting block 21 as the center. The two jaws 51 rotate towards each other, realizing the release of the workpiece 3.

[0039] The working principle of the automatic clamping device for connecting rods provided by this utility model is as follows:

[0040] This utility model provides an automatic clamping device for connecting rods. After the design of connecting the drive component 4 and the clamping component 5, and the diameter of the cylinder telescopic rod 41 is changed to 32mm, the direct pressure of the 100mm diameter cylinder is eliminated, and the action cycle of the clamping component 5 is also increased to 1 second. While reducing the volume of the cylinder telescopic rod 41, the clamping speed of the gripper 51 is increased.

[0041] Compared with related technologies, the automatic clamping device for connecting rods provided by this utility model has the following advantages:

[0042] This utility model provides an automatic clamping device for connecting rods. After the design of connecting the driving component 4 and the clamping component 5, and the diameter of the cylinder telescopic rod 41 is changed to 32mm, the action cycle of the clamping component 5 is also increased to 1 second. This reduces the volume of the cylinder telescopic rod 41 while increasing the clamping speed of the gripper 51.

[0043] Second Embodiment

[0044] Please refer to the following: Figure 3 Based on the automatic link clamping device provided in the first embodiment of this application, the second embodiment of this application proposes another automatic link clamping device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0045] Specifically, the second embodiment of this application provides an automatic clamping device for a connecting rod, wherein the connecting block 21 is provided with an auxiliary component 6, the auxiliary component 6 includes a connecting rod 61, the connecting rod 61 is movably embedded in the connecting groove 22, and a return spring 62 is fixedly connected to the bottom of the connecting rod 61.

[0046] A groove is formed inside the connecting block 21 at the bottom of the connecting groove 22. The top of the connecting rod 61 is slidably embedded in the connecting groove 22, and the bottom is slidably embedded in the groove. The return spring 62 is fixedly connected to the bottom of the connecting rod 61 and is movably embedded in the groove. There are two transmission rods 63, and the two ends of the two transmission rods 63 are respectively rotatably connected to the left and right ends of the top of the connecting rod 61. A groove is formed inside the movable seat 1 at the left and right ends near the top of the connecting groove 22. There are two clamping blocks 64, and the two clamping blocks 64 are slidably embedded in the two grooves respectively. The two grooves are connected to the inside of the connecting groove 22. The other ends of the two transmission rods 63 are respectively rotatably connected to the surface of the two clamping blocks 64.

[0047] The two ends of the connecting rod 61 are movably connected to the transmission rod 63, and the other end of the transmission rod 63 is movably connected to the clamping block 64. The clamping block 64 is fixedly connected to both ends of the workpiece 3 embedded in the connecting groove 22.

[0048] When one end of the workpiece 3 is embedded in the connecting groove 22, pressure is applied to the connecting rod 61, causing one end of the two transmission rods 63 to slide. The angle of the two transmission rods 63 changes, and the other end pulls the two clamping blocks 64 to move relative to each other. This connects to the surface of the workpiece 3 embedded in the connecting groove 22, achieving secondary clamping of the workpiece 3. When both ends of the workpiece 3 are disengaged from the connecting groove 22, the connecting rod 61 slides upward to reset under the elastic force of the return spring 62, and the two transmission rods 63 push the two clamping blocks 64 to slide towards each other, thus releasing the workpiece 3.

[0049] The working principle of the automatic clamping device for connecting rods provided by this utility model is as follows:

[0050] When the workpiece 3 is embedded in the connecting groove 22, the moving seat 1 presses the two ends of the workpiece 3. During this process, the two ends of the workpiece 3 exert pressure on the connecting rod 61, causing the return spring 62 to compress and drive one end of the two transmission rods 63 to move downward. The angle of the two transmission rods 63 changes, and the other end pulls the two clamping blocks 64 to slide relative to each other until the two ends of the workpiece 3 embedded in the connecting groove 22 are clamped and fixed.

[0051] Compared with related technologies, the automatic clamping device for connecting rods provided by this utility model has the following advantages:

[0052] This utility model provides an automatic clamping device for connecting rods. By pressing the workpiece 3, the transmission rod 63 drives the two clamping blocks 64 to move relative to each other, thereby clamping and fixing the workpiece 3 embedded in the connecting groove 22. The device is equipped with secondary clamping protection, which increases the safety of the device.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
