[0003] To address the aforementioned problems, a pipe welding device with positioning and rotation functions is proposed. Utility Model Content

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.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figures 1-3 A pipe welding device with positioning and rotation function includes a workbench 1 and a fixed frame 2 fixedly connected to the top of the workbench 1. A telescopic cylinder 21 is fixedly connected to the top of the fixed frame 2, and a welding component 22 is fixedly connected to the output end of the telescopic cylinder 21. A placement frame 11 is also fixedly connected to the top of the workbench 1. The placement frame 11 is equipped with a conveying mechanism, which conveys the pipe. The conveying mechanism includes a motor 111 fixedly connected to the left and right ends of the placement frame 11. A sliding frame 12 is slidably connected to the placement frame 11, and two sets of sliding frames 12 are provided.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1: To address the issue that existing pipe welding equipment often relies on a single clamping mechanism to hold and fix the pipe, requiring the pipe to be loosened and its position changed when welding operations are needed at different locations, thus affecting work efficiency, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, a transmission screw 112 is fixedly connected to the output end of motor 111. A connecting block 113 is threaded onto the transmission screw 112. Two sets of connecting blocks 113 are fixedly connected to two corresponding sliding frames 12. A heat sink 121 is fixedly connected to the top of the sliding frame 12. A motor 122 is fixedly connected inside the heat sink 121. A worm gear 123 is fixedly connected to the output end of motor 122. A worm wheel 124 is meshed with one side of the worm gear 123. The worm wheel 124 is rotatably connected inside the sliding frame 12. A connecting frame 13 is fixedly connected to the worm wheel 124. A connecting frame 13 is provided on the outer side of the connecting frame 13. The knob 131 is rotatably connected to the internal part of the connecting frame 13 via a screw 132 with both positive and negative threads. Sliding blocks 133 are threaded to both ends of the screw 132, and these sliding blocks 133 are slidably connected inside the connecting frame 13. A mounting block 134 is fixedly connected to one side of the sliding block 133, and a spring telescopic rod 135 is fixedly connected to one side of the mounting block 134. A clamping pad 136 is fixedly connected to the bottom of the spring telescopic rod 135. When clamping the pipes is required, the two sets of pipes can be placed inside the corresponding connecting frame 13, and the knob located on the connecting frame 13 can be pulled. Turn knob 131, and then rotate knob 131. Knob 131 drives the positive and negative thread screw 132 to rotate, thereby causing the two sets of sliding blocks 133 to move. The two sets of sliding blocks 133 can drive the two sets of mounting blocks 134 to move. The mounting blocks 134 clamp the pipe through the clamping pad 136, and under the action of the spring telescopic rod 135, the clamping pad 136 can be stably clamped to the pipe. After fixing, the motor 111 located on one side of the placement frame 11 can be started. The motor 111 drives the transmission screw 112 to rotate, thereby causing the connecting block 113 to drive the sliding frame 12 to move. The moving frame 12 drives the two sets of pipes to move. When it moves into the interior of the fixed frame 2, the telescopic cylinder 21 located on the fixed frame 2 can be activated. The telescopic cylinder 21 drives the welding assembly 22 to descend, which can perform welding operations on the pipes. When it is necessary to change the welding operation, the second motor 122 located inside the heat sink box 121 can be activated. The second motor 122 drives the worm gear 123 to rotate, which in turn causes the worm wheel 124 to rotate. The worm wheel 124 drives the connecting frame 13 to rotate, which in turn causes the pipes to rotate. At this time, the welding position of the pipes can be changed, realizing the function of conveniently adjusting the welding position while clamping the pipes.

[0026] Example 2: To address the problem that most existing pipe welding devices lack a positioning mechanism in their fixing mechanism, which can lead to the rotation of knob 131 causing the clamping pad 136 to move and thus losing its clamping effect on the pipe, this embodiment discloses the following technical solution, specifically as follows: Figure 5As shown, a spring telescopic rod 14 is fixedly connected to the top of the positive and negative threaded screw 132. The spring telescopic rod 14 is fixedly connected to the knob 131. A friction block 141 is fixedly connected to the bottom of the knob 131. A friction block 142 is also fixedly connected to the outside of the connecting frame 13. The friction block 142 matches the friction block 141. During the welding of the pipe, the spring telescopic rod 14 causes the knob 131 to move, which in turn causes the friction block 141 at the bottom of the knob 131 to come into contact with the friction block 142 on the outside of the connecting frame 13. This prevents the knob 131 from rotating easily. When it is necessary to release the pipe, pull the knob 131. The knob 131 causes the friction block 141 to separate from the friction block 142. The knob 131 can then be rotated to adjust the clamping state, achieving a stable clamping effect on the pipe and preventing rotation.
