Description

Technical Field

[0001] This utility model belongs to the technical field of polyethylene pipe fixing equipment, specifically an anti-shaking clamping device for testing the welding strength of polyethylene pipes. Background Technology

[0002] In the prior art, such as the Chinese patent publication number CN219649684U, a clamping assembly for polyethylene pipe production includes a base plate. A fixing block is fixedly installed on the top of the base plate, and a clamping mechanism for polyethylene pipe production is provided on the top of the base plate. The clamping mechanism includes a bracket fixedly installed on the top of the base plate. A lead screw is rotatably installed on the right side of the fixing block, extending through to the right side of the bracket. A first motor is fixedly installed on the top of the base plate, located on the right side of the bracket. This clamping assembly for polyethylene pipe production drives a turntable installed at its output end to rotate forward through two second motors installed inside two mounting boxes. Then, through two connecting rods, it can drive two top blocks and clamping plates to move closer and wider, thereby clamping polyethylene pipes of different diameters for production. Subsequently, the first motor drives the lead screw to rotate forward and backward, forcing the internal thread block and the clamping mechanism installed on its top to move left and right, thereby achieving the effect of easily adjusting the clamping force position.

[0003] When welding polyethylene pipes, two independent polyethylene pipes need to be spliced ​​together using a clamping device before welding. Since the two independent polyethylene pipes are set up independently, they are prone to shaking during the welding process. Therefore, the clamping effect of the clamping device is required to be high. This device proposes an anti-shaking clamping device to prevent the polyethylene pipes from shaking during the welding process. Utility Model Content

[0004] This utility model provides an anti-shaking clamping device for testing the welding strength of polyethylene pipes, in order to solve the technical problem in the prior art where the clamping device does not provide stable support for the two independent polyethylene pipes during the welding process, resulting in shaking.

[0005] To solve the above problems, the present invention provides an anti-sway clamping device for testing the welding strength of polyethylene pipes, which adopts the following technical solution: An anti-sway clamping device for testing the welding strength of polyethylene pipes includes a base. Two mutually symmetrical tracks are fixedly installed on the top of the base. Two sets of sliders are slidably connected inside the two tracks. A first support plate and a second support plate are fixedly installed above the two sets of sliders. Clamping mechanisms are fixedly installed on the inner and outer sides of the first and second support plates. Support rods are fixedly connected to the edges of the first and second support plates. A support ring is fixedly connected to the top of the support rod. Locking rods are fixedly connected to the outer sides of the two sets of sliders. Locking rings are threadedly connected to the outer side of the locking rods. The clamping mechanism is in two sets, and each set of the clamping mechanism has two polyethylene pipes installed inside. The number of the support rings is two, and the inner side of each of the two support rings is fixedly connected with an anti-slip pad; The polyethylene pipes are installed inside the two sets of clamping mechanisms. The two polyethylene pipes are clamped and fixed by the two sets of clamping mechanisms respectively. Then, by adjusting the first support plate and the second support plate, the first support plate and the second support plate move inside the track by sliders. During this process, the first support plate and the second support plate drive the two polyethylene pipes to move forward, and the two polyethylene pipes can be joined together. Then, the ends of the polyethylene pipes are supported by the support rings, and the support rings are fixed to the edges of the first support plate and the second support plate by the support rods. One end of the polyethylene pipe is clamped by the clamping mechanism, and the other end of the polyethylene pipe is supported by the support rings, so that the two polyethylene pipes have extremely strong stability during the welding process and prevent the polyethylene pipes from shaking during the welding process.

[0006] As a further improvement, mounting blocks are fixedly connected to both sides of the base, and bolts are threaded into the mounting blocks. The number of mounting blocks is four, and the four mounting blocks are distributed in a rectangular array. The four mounting blocks are distributed on the left and right sides of the outside of the base. The four mounting blocks are fixed to the base surface by bolts, thereby fixing the base on the base surface. The polyethylene pipe maintains the stability of the base during the welding process. As a further improvement, the clamping mechanism includes a clamping sleeve, a shock absorber fixedly installed on the inner wall of the clamping sleeve, a screw threadedly connected to the inside of the clamping sleeve, a clamping ring at the bottom of the screw, and a cavity adapted to the screw at the top of the clamping ring. The screw is rotatably connected to the top of the clamping ring through the cavity. Multiple anti-slip protrusions are fixedly connected to the inner side of the clamping ring, distributed in a fan-shaped array. The screw extends through to the outside of the clamping sleeve, and a handle is fixedly connected to the top of the screw. (Polyethylene pipe extension...) The handle is twisted inside the clamping sleeve, causing it to move the screw. The clamping ring contacts the outer wall of the polyethylene pipe, thus locking the polyethylene pipe inside the clamping sleeve. The polyethylene pipe then contacts the shock absorber. During welding, when the polyethylene pipe vibrates, the shock absorber dampens the impact force. Multiple anti-slip protrusions are distributed on the inner side of the clamping ring and contact the outer wall of the polyethylene pipe, creating friction to prevent the polyethylene pipe from shifting.

[0007] As a further improvement, the first support plate and the second support plate are symmetrical to each other, and the first support plate and the second support plate are L-shaped.

[0008] In summary, this utility model provides an anti-shaking clamping device for testing the welding strength of polyethylene pipes. By adjusting the distance between the first and second support plates according to the length of the polyethylene pipe, the clamping mechanism and the support ring clamp and support both ends of the polyethylene pipe, giving the polyethylene pipe extremely strong stability during the welding process and preventing it from shaking.

The two polyethylene pipes 12 are clamped and fixed by the two sets of clamping mechanisms 7 respectively. Then, by adjusting the first support plate 4 and the second support plate 5, the first support plate 4 and the second support plate 5 move inside the track 2 through the slider 3. During this process, the first support plate 4 and the second support plate 5 drive the two polyethylene pipes 12 to move forward, and the two polyethylene pipes 12 can be connected. Then, the end of the polyethylene pipe 12 is supported by the support ring 9, and the support ring 9 is fixed at the edge of the first support plate 4 and the second support plate 5 by the support rod 8. One end of the polyethylene pipe 12 is clamped by the clamping mechanism 7, and the other end of the polyethylene pipe 12 is supported by the support ring 9, so that the two polyethylene pipes have extremely strong stability during the welding process and prevent the polyethylene pipes from shaking during the welding process. For further improvements to this utility model, please refer to Figures 1 to 4As shown, mounting blocks 13 are fixedly connected to both sides of the base 1. Bolts 6 are threaded into the interior of each mounting block 13. There are four mounting blocks 13, which are arranged in a rectangular array. The four mounting blocks 13 are distributed on the left and right sides of the base 1 and are fixed to the base surface by bolts 6, thus fixing the base 1 to the base surface.
