Description

Technical Field

[0001] This utility model relates to the field of EGR pipe processing technology, and in particular to a welding clamping device suitable for EGR pipes. Background Technology

[0002] EGR pipes are an important component of the exhaust gas recirculation system, mainly used to connect the engine's exhaust pipe and intake pipe. EGR pipes are usually connected by welding, so a clamping device is required. This is a tool that can clamp and fix the clamping device, which can promote the stability of the EGR pipe fixation and promote the success of the welding.

[0003] Currently, most EGR pipe welding clamping devices have limitations in use because different models of vehicles use EGR pipes with different curvatures and diameters. This means that clamping devices of different sizes are required for EGR pipes of different sizes, which makes clamping use quite limited and seriously affects the welding progress.

[0004] Therefore, those skilled in the art have provided a hospital outpatient patient guidance device to solve the problems mentioned in the background art. Utility Model Content

[0005] The main purpose of this utility model is to provide a welding clamping device suitable for EGR pipes. Through the magnetic attraction between the sliding frame and the fixed frame, the position of the sliding frame can be flexibly adjusted. Through the cooperation between the limiting groove and the limiting post, under the action of the spring, the problem of clamping and fixing different arc-shaped pipes can be solved. Through the cooperation between the arc block and the air bladder, under the action of the air pump, the problem of fixing pipes of different diameters can be solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A welding clamping device for EGR pipes, comprising a frame and a pipe body, wherein the lower end of the frame is provided with a controllable adjustment component, which can adjust the clamping position area according to the curvature of the EGR pipe.

[0008] It also includes:

[0009] The clamping assembly is mounted on the adjusting assembly and can adjust the clamping angle according to the curvature of the EGR pipe to make the clamping more stable.

[0010] The above technical solution allows for flexible adjustment of the clamping angle using the adjustment components, facilitating the fixing of pipes with different bends. The clamping components can also be used to clamp and fix pipes of different diameters.

[0011] Preferably, the adjustment assembly includes electromagnetic rods disposed on both sides of the lower end of the frame to improve stability. Two sliding frames are slidably sleeved on each of the two electromagnetic rods. Electromagnetic blocks are sleeved on the sliding frames. Fasteners for clamping the sliding frames are threaded onto the upper ends of the plurality of electromagnetic blocks. Limiting grooves are formed at the lower ends of the plurality of electromagnetic blocks. Limiting posts are slidably disposed on the inner walls of the plurality of limiting grooves.

[0012] Through the above technical solution, the sliding frame slides on the electromagnetic rod, and under the action of the electromagnetic block and the limiting groove, the rotation angle of the limiting column can be adjusted.

[0013] Preferably, the clamping assembly includes a vacuum pump mounted on a limiting post, which can perform vacuuming and venting. One end of the vacuum pump is connected to an arc block, and the inner wall of the arc block is provided with an inflatable air bladder. An air supply pipe is provided between the air bladder and the output end of the vacuum pump.

[0014] The above technical solution allows for the clamping and fixing of the tube body by pumping air into the airbag and using the action of the arc block.

[0015] Preferably, a fixing ring is fixedly sleeved on the upper end of the outer wall of the limiting post, and a spring is provided on the outer wall of the limiting post between the fixing ring and the electromagnetic block.

[0016] The above technical solution utilizes a spring that can achieve a resetting function.

[0017] Preferably, the toothed block on the limiting post is engaged with the limiting groove.

[0018] Preferably, a controller is provided at one end of the frame, and the controller is electrically connected to the electromagnetic rod, the electromagnetic block and the air pump.

[0021] Preferably, the electromagnetic block and the limiting post are magnetically attracted to each other.

[0022] The above technical solution allows for the fixation of the limiting post by energizing the electromagnetic block.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] I. In this utility model, an air pump is used to pump air into the air bladder on the inner wall of the arc block, causing the air bladder to expand. The two arc blocks then move towards the center, which can clamp and fix tubes of different diameters.

[0025] II. In this utility model, the magnetic attraction between the electromagnetic rod and the sliding frame allows the operator to flexibly adjust the position of the sliding frame. Under the action of the electromagnetic block and the fastener, pressing down on the air pump causes the fixing ring on the limiting post to squeeze the spring downward, allowing the air pump to rotate. When the air pump is released, the toothed block on the limiting post automatically moves upward and engages with the limiting groove under the reset action of the spring. Under the magnetic attraction of the electromagnetic block, the limiting post is magnetically fixed, thereby fixing the angle of the air pump, which facilitates the clamping and fixing of pipes with different curvatures.

[0033] Example: Figure 1-5 As shown, a welding clamping device suitable for EGR pipe includes a frame 1 and a pipe body 17. The lower end of the frame 1 is provided with a controllable adjustment component 2, which can adjust the clamping position area according to the curvature of the EGR pipe.

[0034] It also includes:

[0035] The clamping component 4 is mounted on the adjusting component 2. The clamping angle can be adjusted according to the curvature of the EGR pipe to make the clamping more stable. The adjusting component 2 can be used to flexibly adjust the clamping angle, which is convenient for fixing pipes with different bends. The clamping component 4 can clamp and fix pipes of different diameters.

[0036] The adjustment assembly 2 includes electromagnetic rods 6 disposed on both sides of the lower end of the frame 1 to improve stability. Two sliding frames 16 are slidably mounted on each of the two electromagnetic rods 6. Electromagnetic blocks 13 are mounted on the sliding frames 16. Fasteners 5 for clamping the sliding frames 16 are threaded onto the upper ends of the multiple electromagnetic blocks 13. Limiting grooves 15 are formed at the lower ends of the multiple electromagnetic blocks 13. Limiting posts 14 are slidably disposed on the inner walls of the multiple limiting grooves 15. The sliding frames 16 slide on the electromagnetic rods 6. Under the action of the electromagnetic blocks 13 and the limiting grooves 15, the rotation angle of the limiting posts 14 can be adjusted.

[0037] The clamping assembly 4 includes a vacuum pump 8 mounted on the limiting post 14, which can perform vacuuming and venting. One end of the vacuum pump 8 is connected to an arc block 9. An inflatable air bladder 10 is provided on the inner wall of the arc block 9, and an air supply pipe 7 is provided between the air bladder 10 and the output end of the vacuum pump 8. By pumping air into the air bladder 10, the tube 17 can be clamped and fixed under the action of the arc block 9.

[0038] A retaining ring 11 is fixedly sleeved on the upper part of the outer wall of the limiting post 14. A spring 12 is provided on the outer wall of the limiting post 14 between the retaining ring 11 and the electromagnetic block 13. The spring 12 can play a resetting role.

[0039] The toothed block on the limiting post 14 engages with the limiting groove 15.

[0040] A controller 3 is provided at one end of the frame 1. The controller 3 is electrically connected to the electromagnetic rod 6, the electromagnetic block 13 and the air pump 8.

The two tubes 17 are placed between corresponding sets of arc blocks 9. Then, under the action of the electromagnetic block 13 and the fastener 5, pressing down on the air pump 8 causes the fixing ring 11 on the limiting post 14 to compress the spring 12, allowing the air pump 8 to rotate. Releasing the air pump 8 allows the spring 12 to return to its original position. The toothed block on the limiting post 14 automatically moves up and engages with the limiting groove 15. Under the magnetic attraction of the electromagnetic block 13, the limiting post 14 can be magnetically fixed, thereby fixing the angle of the air pump 8.
