[0002] Before the anti-collision pipe of an electric vehicle is welded, it needs to be clamped and positioned and cleaned. Workers usually use an air gun to clean the dust on the surface, and use a deburring knife to process the burrs visible to the naked eye. However, fine burrs that are difficult to detect with the naked eye are likely to adhere to the outer side wall of the anti-collision pipe. These burrs are easily overlooked, and once ignored, they are easily forgotten during welding, thus affecting the welding quality.

[0003] Therefore, it is very necessary to propose a positioning fixture for processing the anti-collision pipe of an electric vehicle to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a positioning fixture for processing the anti-collision pipe of an electric vehicle, so as to solve the problem that when the anti-collision pipe is welded, fine burrs that are difficult to detect with the naked eye adhere to the outer side wall of the anti-collision pipe. Due to the burrs being difficult to detect, they are easily overlooked and easily forgotten during welding, thus affecting the welding quality.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A positioning fixture for processing the anti-collision pipe of an electric vehicle, including an operating table and an electric fixture.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model provides as Figure 1 - Figure 4A positioning fixture for processing an anti-collision tube of an electric vehicle as shown includes an operating table 1 and an electric fixture 2. The electric fixture 2 is fixedly arranged on the surface of the operating table 1. A movable jaw 3 is slidably arranged on the electric fixture 2. A fixed jaw 4 is fixedly arranged on the surface of the electric fixture 2. An arc-shaped blade 5 is arranged on the surface of the movable jaw 3. The fixed jaw 4 is used to carry the anti-collision tube, and the movable jaw 3 can be used to drive the arc-shaped blade 5 to remove dust and burrs on the outer side wall of the anti-collision tube during positioning. The electric fixture 2 includes a motor and a transmission mechanism. Usually, the transmission mechanism is driven by the motor to perform the operation of clamping or releasing the movable jaw 3, which is the prior art;

[0021] On one side of the electric fixture 2 on the surface of the operating table 1, there is also a welding device 14 for welding the anti-collision tube of the electric vehicle, which is the prior art and will not be elaborated here.

[0022] Considering that the anti-collision tube will shake when placed in the fixed fixture, a spring 10 is fixedly arranged on the inner wall of the fixed jaw 4. One end of the spring 10 is fixedly provided with a clamping plate 11. A non-slip sleeve 13 is fixedly arranged at the bottom of the clamping plate 11. The non-slip sleeve 13 is arc-shaped. The non-slip sleeve 13 can increase the friction with the outer side wall of the anti-collision tube, and the arc-shaped setting can better fit on the outer side wall of the anti-collision tube, thereby improving the firmness of clamping.

[0023] Both sides of the clamping plate 11 slide with the inner wall of the fixed jaw 4. Place the anti-collision tube to be welded on the inner wall of the fixed fixture, and insert one end of the anti-collision tube into the arc-shaped blade 5. The clamping plate 11 can be slid upward. At this time, the spring 10 is stretched. When the clamping plate 11 is slid upward to a suitable position, release the clamping plate 11 by hand. The spring 10 resumes deformation and pushes the clamping plate 11 to reset. While the clamping plate 11 resets, it fits with the outer side wall of the anti-collision tube to press the anti-collision tube, so that the anti-collision tube can be positioned in the fixed fixture.

[0024] Furthermore, an airbag 6 is fixed on the inner wall of the electric fixture 2. One end of the airbag 6 is fixed to the inner wall of the fixed jaw 4, and the other end of the airbag 6 is fixed to the inner wall of the movable jaw 3. One side of the airbag 6 is connected with an air outlet pipe 7. The air outlet pipe 7 passes through the electric fixture 2. The top of the air outlet pipe 7 is connected with an air outlet 9, and the air outlet 9 faces the movable jaw 3. The other end of the airbag 6 is connected with an air inlet pipe 8. One-way valves are arranged in both the air outlet pipe 7 and the air inlet pipe 8. Through holes 12 are opened on one side of the movable jaw 3, facilitating the air ejected from the air outlet 9 to reach the place where the burrs and dust on the anti-collision tube are scraped off.

[0025] Mainly, when positioning the anti-collision tube of the electric vehicle, it can scrape off the dust and burrs attached to the surface of the anti-collision tube to ensure the cleanliness of the welding area. Secondly, it can also blow away the scraped dust and burrs during the positioning and clamping process, effectively avoiding the influence of these impurities on the welding quality.

[0026] When driving the electric fixture 2 to work, the movable jaw 3 slides with the arc blade 5 towards the fixed jaw 4, and the arc blade 5 scrapes along the outer wall of the anti-collision pipe. While the movable jaw 3 slides towards the fixed jaw 4, the airbag 6 is compressed. The gas in the airbag 6 blows air from the air outlet pipe along the air outlet 9 towards the direction of scraping burrs and dust on the outer wall of the anti-collision pipe, so that the scraped burrs and dust are blown off from the surface of the anti-collision pipe;

[0027] After scraping burrs and dust on the outer wall of the anti-collision pipe, drive the movable jaw 3 to reset. At this time, the movable jaw 3 contacts the outer wall of the arc-shaped pipe again with the arc blade 5, so that the dust and burrs on the outer wall of the anti-collision pipe are further scraped off. As the movable jaw 3 is reset and pulls the airbag 6 to recover, the intake pipe 8 starts to intake air at this time, and the outlet pipe 7 exhausts air under the influence of the one-way valve. At this time, drive the welding device 14 to weld the welded part of the anti-collision pipe.
