During the welding production of the steel front bumper beam, the following pain points exist regarding the assembly and welding of the tow ring: 1. High heat conduction during welding, the fixture structure is not conducive to heat dissipation, and commonly used induction signals are easily damaged by prolonged operation in high-temperature environments; 2. Excessive welding dust splashes, infrequent cleaning, easily causing mechanism jamming, and failure of the fixture's error prevention system. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a front anti-collision beam traction ring error prevention structure, which can solve the following technical problems: high heat conduction during welding, the fixture structure is not conducive to heat dissipation, and commonly used induction signals are easily damaged when working in a high-temperature environment for a long time; large amount of welding dust splashes, infrequent cleaning, easy to cause mechanism jamming, and failure of the fixture error prevention.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a front anti-collision beam traction ring anti-misalignment structure, including a base, which serves as the main support part of the anti-misalignment structure, used to support other parts and fix the anti-misalignment structure to a welding device; a placement groove, the top surface of which has a placement groove that fits into the annular part of the traction ring; a receiving mating surface, which is located at the top edge of the base, after the traction ring is placed in the placement groove and fitted, the special shape of the traction ring connection part fits into the receiving mating surface, thereby giving the placement of the traction ring a specific directionality; a positioning pin, which is fixed inside the base, and the traction ring is fitted onto the outside of the positioning pin for positioning the traction ring; and a pressure rod, which passes through the inside of the positioning base and is adjacent to the positioning pin, with a T-block connected to the bottom of the pressure rod via a connecting rod, so that the T-block can be detected by a proximity switch when the traction ring presses down the pressure rod.

[0005] As a preferred embodiment of this utility model, the base includes a fixed base and a positioning base, the fixed base is located below the positioning base, and the fixed base is connected to the welding device by bolts.

[0006] As a preferred embodiment of this utility model, a second stepped through hole is provided at the center of the top surface of the positioning seat, a placement groove is provided on the inner side of the top surface of the positioning seat, and a receiving mating surface is provided at the edge of the top surface of the positioning seat.

[0007] As a preferred technical solution of this utility model, the top surface of the positioning seat is provided with a first stepped through hole, the first stepped through hole is adjacent to a second stepped through hole, a guide block is provided inside the first stepped through hole, a pressure rod is fixed on the top surface of the guide block, and a connecting rod is provided between the guide block and the T-block, and a spring sleeved on the outside of the connecting rod is provided inside the first stepped through hole, a limiting groove is provided on the outside of the positioning pin, and the top of the pressure rod is in contact with the inner top wall of the limiting groove.

[0010] As a preferred embodiment of this utility model, the outer side of the fixed base is provided with a threaded hole, and a bolt is screwed into the threaded hole and can contact the proximity switch.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: 1. By designing placement grooves and receiving mating surfaces, the traction ring can be placed more snugly above the positioning seat, giving the traction ring directional placement. The positioning pin design ensures the inner side of the traction ring mates with the positioning pin, resulting in more precise positioning. The downward pressure of the traction ring on the pressure rod allows the proximity switch to detect the downward movement of the T-block, thus outputting a signal to the welding workstation to correctly complete the subsequent welding process. This reduces the occurrence of incorrect / missing traction ring installations, lowering the scrap rate. Because the device is a certain distance from the welding area, and the proximity switch used for detection is located internally, there is less need for excessive cleaning of the anti-error structure from welding slag or dust, thus improving production efficiency. Simultaneously, it reduces the frequency of replacing damaged sensing signals, lowering fixture maintenance / usage costs and saving costs. 2. By designing an annular inclined groove on the outside of the fixing rod, the bolt can be screwed into the threaded hole above and inserted into the annular inclined groove, thereby fixing the positioning pin and facilitating the disassembly and replacement of the positioning pin. 3. The guide block is pushed up by the spring, so that the pressure rod is pressed into the limiting groove, which facilitates the precise reset of the pressure rod. Attached Figure Description

Detailed Implementation

[0013] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0014] Example: Please refer to Figures 1-5 As shown, this utility model provides a front anti-collision beam traction ring anti-misalignment structure, including a base composed of a fixed base 1 and a positioning seat 5. After being integrally formed, it is completed by cutting and drilling. A second stepped through hole 19 is opened in the middle of the top surface of the positioning seat 5. The large diameter hole of the second stepped through hole 19 is at the top, and the small diameter hole leads to the fixed base 1 below. The bottom of the positioning pin 9 is welded or cut with a fixing rod 17. An annular inclined groove 18 is opened in the middle of the fixing rod 17. The positioning pin 9 is placed in the second stepped through hole 19, and the fixing rod 17 is inserted into the small hole of the second stepped through hole 19. The fixing rod 17 and the small hole of the second stepped through hole 19 can fit tightly, so that the positioning pin 9 is not easy to shake. A threaded hole 12 with the same height as the annular inclined groove 18 is opened on the outer side of the positioning seat 5. A bolt is threaded in the threaded hole 12. By rotating the bolt, the other end of the bolt is inserted into the annular inclined groove 18, thereby fixing the positioning pin 9.

[0015] like Figures 1-5As shown, the inner wall of the top surface of the positioning seat 5 is provided with a placement groove 6, and the outer side of the positioning seat 5 is provided with a receiving mating surface 13. After the traction ring is put on the outside of the positioning pin 9, the angle of the traction ring is adjusted so that the connection between the ring structure of the traction ring and the straight rod can be placed on the receiving mating surface 13. The specific shape of the receiving mating surface 13 can be determined according to the traction ring to be welded. After the traction ring is put on the outside of the positioning pin 9, the traction ring can fit perfectly with the placement groove 6 and the receiving mating surface 13, so that the traction ring placed on the anti-misalignment structure has directionality.

[0016] like Figures 1-5 As shown, a first stepped through hole 16 is provided on the inner side of the positioning seat 5. A guide block 15 is provided on the inner side of the first stepped through hole 16. A pressure rod 7 is provided on the top of the guide block 15 and extends upward. A connecting rod 4 is provided below the guide block 15 and extends downward a certain distance. The diameters of the connecting rod 4, the pressure rod 7, and the guide block 15 increase sequentially. A spring 14 is sleeved on the outside of the connecting rod 4 located in the first stepped through hole 16. The elastic force of the spring 14 can push the guide block 15 upward, thereby resetting the pressure rod 7. To prevent the spring 14 from pushing the pressure rod 7 upward... The height is relatively high, so that the side of the positioning pin 9 is provided with a limiting groove 8, and the top surface of the pressure rod 7 is pressed against the top wall of the limiting groove 8, so that the pressure rod 7 can only maintain a certain height after resetting. The bottom of the connecting rod 4 is fixed with a T-shaped block 3, and the side of the fixed base 1 is provided with a guide groove 2, which can fit with the T-shaped block 3. The side of the fixed base 1 is provided with a mounting hole 11, and a proximity switch 10 is placed in the mounting hole 11. The side of the fixed base 1 is provided with a threaded hole 12, and a bolt is threaded into the threaded hole 12. The proximity switch 10 is fixed by pressing the bolt against it. Specific working principle: In use, the traction ring is placed on the outside of the positioning pin 9 by a robotic arm or manually. The traction ring fits snugly onto the placement groove 6 and the receiving mating surface 13. As the traction ring falls into the placement groove 6, it presses down on the pressure rod 7, causing the pressure rod 7 to push the connecting rod 4 downward, thereby moving the T-block 3 downward. The proximity switch 10 senses the T-block 3 and outputs a signal to the welding workstation, thus correctly completing the subsequent welding process. If the traction ring is installed backwards or is missing, the pressure rod 7 will not be pressed down in the correct position or will not be able to be pressed down. The proximity switch 10 will not sense the T-block 3 and will not be able to output the correct signal to the welding workstation, thus preventing the subsequent welding process from proceeding. In order to ensure the stable positioning of the traction ring, the following can be selected: a pressing cylinder can be installed directly above the anti-misalignment structure. The extension end of the cylinder faces downward and is connected to a pressure ring, which can stably press the traction ring into the placement groove 6 to prevent the traction ring from shaking.
