Description

Technical Field

[0001] This utility model relates to the field of clamps for welded pipes, specifically a clamp for welded pipes. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. It is also called a clamp. In a broader sense, any device used to quickly, conveniently and safely install a workpiece in any step of the process can be called a fixture.

[0003] Existing pipe welding clamps can only clamp and fix two pipe sections. However, during welding, the pipe needs to be rotated so that the welding flux surrounds the joint between the two pipe sections. Existing clamps cannot rotate the pipe, resulting in low welding efficiency. Therefore, a new pipe welding clamp is proposed to solve the above-mentioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a pipe welding clamp that is easy to use and solves the problem that most existing pipe welding clamps can only clamp and fix two pipe sections, while the pipe needs to be rotated during welding so that the welding flux surrounds the joint of the two pipe sections. Existing clamps cannot rotate the pipe, resulting in low welding efficiency.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A clamp for welding pipe includes a platform, an adjustment mechanism extending to the top of the platform is provided inside the platform, a fixing mechanism located on one side of the adjustment mechanism is fixedly connected to the top of the platform, a support mechanism located between the fixing mechanism and the adjustment mechanism is fixedly connected to the top of the platform, and a transmission mechanism connected to the support mechanism is provided at the bottom of the platform.

[0008] The top of the adjustment mechanism and the support mechanism and the bottom of the fixing mechanism are all fixedly connected with wheels;

[0009] The adjustment mechanism includes a lead screw, which is rotatably connected to the inside of the platform. One end of the lead screw is fixedly connected to a control panel located on the outside of the platform. A screw tube is threadedly connected to the outside of the lead screw. A slide plate that is slidably connected to the platform and located above the platform is fixedly connected to the top of the screw tube. Two first support rods, which are symmetrically distributed front and back, are fixedly connected to the top of the slide plate. The two rotating wheels are rotatably connected to the two first support rods respectively.

[0010] The fixing mechanism includes two sleeves, both of which are fixedly connected to the top of the platform and are symmetrically distributed front to back. A sliding rod is slidably connected inside each sleeve. A spring plate is fixedly connected to the bottom of each sliding rod. A spring located outside the sliding rod is fixedly connected between the top of each spring plate and the inner wall of the sleeve on the same side. A parallel plate located above the sleeve is fixedly connected to the top of each sliding rod.

The two second support rods are symmetrically distributed front to back, and the two rotating wheels are rotatably connected to the bottom of the two second support rods respectively.

[0011] The beneficial effects of this utility model are: by driving the rotating wheel connected to the support mechanism to rotate through the transmission mechanism, the pipe fixed between multiple rotating wheels will rotate circumferentially, thereby keeping the welding point fixed while welding the pipe, and the circumferential rotation of the pipe will enable it to automatically perform circumferential welding on the pipe.

[0012] This pipe welding clamp has the advantage of being easy to use.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the bottom of the platform is fixedly connected with four support legs arranged in a rectangular array, and the inside of the platform has through holes adapted to the transmission mechanism.

[0016] Furthermore, the left side of both sleeves and the top of the platform are fixedly connected with reinforcing ribs, and the inside of both sleeves is fixedly connected with anti-deviation tubes that are slidably connected to the outside of the slide rod on the same side.

[0017] The beneficial effect of adopting the above-mentioned further solutions is that the reinforcing ribs can improve the structural connection strength.

[0018] Furthermore, the parallel plate is trapezoidal, the tops of the two mounting plates are arc-shaped, and the two mounting plates are fixedly connected by the same tie rod.

[0019] The advantage of adopting the above-mentioned further solution is that the pull rod can improve the grip position, making it easier to lift the parallel plate.

[0020] Furthermore, the support mechanism includes two third support rods, both of which are fixedly connected to the top of the platform and are symmetrically distributed front and back. Two of the rotating wheels are rotatably connected to the top of the two third support rods. There are a total of six rotating wheels, with the two upper rotating wheels located between the four lower rotating wheels.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that the six rotating wheels are arranged in a three-point configuration to contact the outside of the pipe and provide support for the pipe.

[0022] Furthermore, the transmission mechanism is located below the support mechanism. The transmission mechanism includes a motor, which is fixedly connected to the bottom of the platform. A pulley is fixedly connected to the output end of the motor. One of the pulleys, which is rotatably connected to the third support rod, has a groove on its outer side.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the embodiments, by Figure 1-4 The present invention provides a clamp for welding pipes, comprising a platform 1, an adjustment mechanism 2 extending to the top of the platform 1, a fixing mechanism 3 located on one side of the adjustment mechanism 2 fixedly connected to the top of the platform 1, a support mechanism 4 located between the fixing mechanism 3 and the adjustment mechanism 2 fixedly connected to the top of the platform 1, and a transmission mechanism 5 connected to the support mechanism 4 at the bottom of the platform 1.

[0031] The top of the adjusting mechanism 2 and the supporting mechanism 4, and the bottom of the fixing mechanism 3 are all fixedly connected with a rotating wheel 6;

[0032] The adjustment mechanism 2 includes a lead screw 201, which is rotatably connected to the inside of the platform 1. One end of the lead screw 201 is fixedly connected to a control panel 202 located on the outside of the platform 1. A screw tube 203 is threadedly connected to the outside of the lead screw 201. A slide plate 204 that is slidably connected to the platform 1 and located above the platform 1 is fixedly connected to the top of the slide plate 204. Two first support rods 205, which are symmetrically distributed front and back, are fixedly connected to the top of the slide plate 204. Two rotating wheels 6 are rotatably connected to the two first support rods 205 respectively.

[0033] The fixing mechanism 3 includes two sleeves 301, both of which are fixedly connected to the top of the platform 1 and are symmetrically distributed front and back. The interior of each sleeve 301 is slidably connected to a slide rod 302. The bottom of each slide rod 302 is fixedly connected to a spring plate 303. The top of each spring plate 303 and the inner wall of the sleeve 301 on the same side are both fixedly connected to a spring 304 located outside the slide rod 302 on the same side. The top of each slide rod 302 is fixedly connected to the same parallel plate 305 located above the sleeve 301. One side of the parallel plate 305 is fixedly connected to two mounting plates 306 located above the two lower rotating wheels 6. The bottom of each mounting plate 306 is fixedly connected to a second support rod 307, which is symmetrically distributed front and back. The two rotating wheels 6 are rotatably connected to the bottom of the two second support rods 307 respectively.

[0034] The bottom of the platform 1 is fixedly connected with four support legs 7 arranged in a rectangular array, and the inside of the platform 1 is provided with through holes 8 that are compatible with the transmission mechanism 5.

[0035] The pre-set perforation 8 facilitates belt drive of 504 stainless steel;

[0036] The left side of each of the two sleeves 301 is fixedly connected to the top of the platform 1 with a reinforcing rib 9, and the inside of each of the two sleeves 301 is fixedly connected to an anti-deviation tube 10 that is slidably connected to the outside of the slide rod 302 on the same side.

[0037] Reinforcing rib 9 can improve the structural connection strength;

[0038] The parallel plate 305 is trapezoidal, the tops of the two mounting plates 306 are arc-shaped, and the two mounting plates 306 are fixedly connected by the same tie rod 11.

[0039] Pull rod 11 can raise the grip position, making it easier to lift the parallel plate 305;

[0040] The support mechanism 4 includes two third support rods 401. Both third support rods 401 are fixedly connected to the top of the platform 1 and are symmetrically distributed front and back. Two rotating wheels 6 are rotatably connected to the top of the two third support rods 401. There are a total of six rotating wheels 6, with the two upper rotating wheels 6 located between the four lower rotating wheels 6.

[0041] The six rotating wheels are arranged in a three-point configuration to contact the outside of the pipe and provide support for the pipe.

[0042] The transmission mechanism 5 is located below the support mechanism 4. The transmission mechanism 5 includes a motor 501, which is fixedly connected to the bottom of the platform 1. The output end of the motor 501 is fixedly connected to a pulley 502. One of the rotating wheels 6, which is rotatably connected to the third support rod 401, has a groove 503 on its outer side. The groove 503 and the pulley 502 are connected by the same belt 504.

[0043] Belt drives provide smooth transmission and are less prone to shaking, maintaining welding stability while driving the pipeline to rotate.

[0044] Working principle:

[0045] Step 1: Pull up the mounting plate 306 by pulling the lever 11, place the pipe on top of the four rollers 6 below, and when the lever 11 is released, the spring plate 303 is pushed by the spring 304, causing the slide bar 302 to slide down, so that the rollers 6 above press down on the pipe.

[0046] Step 2: When welding the pipe, start the motor 501. The motor 501 drives the belt 504 through the pulley 502 and the groove 503 to drive one of the rotating wheels 6 that is rotatably connected to the third support rod 401 to rotate, thereby driving the pipe to rotate. Since there is a welding point between the two pipe sections, both pipe sections will rotate, which makes it easy to perform circumferential welding on the pipe.

[0047] Step 3: When encountering pipes with different diameters, the control panel 202 can be rotated to drive the lead screw 201 to rotate, thereby driving the slide plate 204 to move through the solenoid 203. This will cause the two rotating wheels 6, which are rotatably connected to the first support rod 205, to move closer to or further away from the third support rod 401, thereby adjusting the placement spacing to suit the current welded pipe.
