The moving block 216 is fixedly connected to the bottom of the base 1. The top of the base 1 is equipped with a spraying device 3 for spraying welding protective agent. The top of the base 1 is equipped with a fixing device 4 for fixing the recessed area of the guide rail. This achieves stable clamping, precise processing, and protective agent spraying of the vehicle door guide rail, improving welding quality and efficiency. The base 5 serves as the foundation of the entire device, supporting components such as the base 1 and the welding machine body 6. The inner wall of the electric slide rail 22 on the top of the base 1 is slidably connected to the electric slider 21, and the inner wall of the electric slider 21 is equipped with a first hydraulic component. Through the cooperation of the electric slide rail 22 and the electric slider 21, the electric slider 21 can be moved horizontally on the top of the base 1. The left side and the bottom of the first hydraulic component are fixedly connected to the first clamping block 25 and the second clamping block 27 respectively. Using the principle of hydraulic transmission, the first hydraulic component can drive the clamping blocks to clamp and fix the door guide rail. The inner wall of the slide groove 215 opened on the top of the base 5 is slidably connected to the moving block 216. The moving block 216 is fixedly connected to the bottom of the base 1. The position of the base 1 can be adjusted by sliding the moving block 216 in the slide groove 215. The spraying device 3 assembled on the top of the base 1 is used to spray welding protective agent on the guide rail before welding to prevent problems such as oxidation during welding. The fixing device 4 is used to fix the concave part of the guide rail to ensure the stability of the welding process.

[0025] The first hydraulic assembly includes a first hydraulic chamber 23. A piston at one end of the first hydraulic chamber 23 is slidably connected to a first hydraulic rod 24. The left side of the first hydraulic rod 24 is fixedly connected to the right side of a first clamping block 25. A piston at one end of the first hydraulic chamber 23 is slidably connected to a second hydraulic rod 26. The second hydraulic rod 26 is fixedly connected to the top of a second clamping block 27. When hydraulic oil enters the first hydraulic chamber 23, it pushes the first hydraulic rod 24 leftward, thereby moving the first clamping block 25 leftward. A piston at the other end of the first hydraulic chamber 23 is slidably connected to a second hydraulic rod 26. The second hydraulic rod 26 is fixedly connected to the top of the second clamping block 27. The hydraulic oil pushes the second hydraulic rod 26 up and down, thereby controlling the raising and lowering of the second clamping block 27. This hydraulic transmission method allows precise adjustment of the clamping block's position and clamping force, ensuring stable clamping of the door rail. The electric slider 21 is fixedly connected to the side of a second hydraulic reservoir 28. A piston at one end of the second hydraulic reservoir 28 is slidably connected to a third hydraulic rod 29, which is fixedly connected to the bottom of the connecting rod 210. A third hydraulic reservoir 211 is fixedly connected to the top of the base 1. A piston at one end of the third hydraulic reservoir 211 is slidably connected to a fourth hydraulic rod 212, which is fixedly connected to the front of the first clamping block 25. A connecting hose connects the second and third hydraulic reservoirs 28 and 211. This hydraulic transmission enables the raising and lowering of the connecting rod 210 and the forward and backward movement of the first clamping block 25, further enhancing the flexibility and adaptability of the device. The electric slider 21 is fixedly connected to the side of the second hydraulic reservoir 28. A piston at one end of the second hydraulic reservoir 28 is slidably connected to a third hydraulic rod 29, which is fixedly connected to the bottom of the connecting rod 210. When hydraulic oil enters the second hydraulic reservoir 28, it pushes the third hydraulic rod 29 up and down, thereby driving the up and down movement of the connecting rod 210. This up and down movement of the connecting rod 210 can adjust the position of the grinder body 7. The top of the base 1 is fixedly connected to a third hydraulic chamber 211. A piston at one end of the third hydraulic chamber 211 slides into a fourth hydraulic rod 212, which is fixedly connected to the front of the first clamping block 25. Hydraulic fluid pushes the fourth hydraulic rod 212 to extend and retract, thereby moving the first clamping block 25 back and forth, enabling precise adjustment of the clamping position. A connecting hose connects the second hydraulic chamber 28 to the third hydraulic chamber 211, allowing hydraulic fluid to flow between them and coordinate the movements of the hydraulic rods.A fourth hydraulic tank 217 is fixedly connected to the top of the base 1, and a fifth hydraulic rod 218 is slidably connected to the piston at one end of the fourth hydraulic tank 217. A fifth hydraulic tank 213 is fixedly connected to the top of the base 5, and a sixth hydraulic rod 214 is slidably connected to the piston at one end of the fifth hydraulic tank 213. The extension and retraction of the fifth hydraulic rod 218 can be used to adjust the height of the base 1 or the position of other related components, and the extension and retraction of the sixth hydraulic rod 214 can be used to control the movement of other components on the base 5, such as the opening and closing of the clamping device, thereby enhancing the flexibility and versatility of the entire device.

[0026] When the above-mentioned device is used, the door guide rail is placed on the top of the base 1, and the electric slide rail 22 is started to make the two electric sliders 21 move toward each other. The electric slider 21 drives the connecting rod 210 to move to the back, and the connecting rod 210 drives the grinder body 7 to grind the front end of the door guide rail. The electric slider 21 drives the first clamping block 25 to contact the door guide rail. When the electric slider 21 continues to move, the first clamping block 25 causes the first hydraulic rod 24 to move to the right through the reaction force. The first clamping block 25 drives the fourth hydraulic rod 212 to move to the right. During the movement of the fourth hydraulic rod 212 to the right, the internal pressure of the third hydraulic chamber 211 and the second hydraulic chamber 28 increases, driving the third hydraulic rod 29 to rise, and the third hydraulic rod 29 The connecting rod 210 is driven to rise, and the connecting rod 210 drives the grinder body 7 to rise. When the first clamping block 25 continues to squeeze the first hydraulic rod 24, the internal pressure of the first hydraulic chamber 23 increases, and the second hydraulic rod 26 descends. The second hydraulic rod 26 drives the second clamping block 27 to fix the top of the door guide rail. At the same time, the first clamping block 25 squeezes the fifth hydraulic rod 218 to move to the left during the movement. During the movement of the fifth hydraulic rod 218, the internal pressure of the fourth hydraulic chamber 217 and the fifth hydraulic chamber 213 increases, driving the sixth hydraulic rod 214 to move to the left. The sixth hydraulic rod 214 drives the base 1 to slide to the left, and the base 1 drives the moving block 216 to slide on the inner wall of the slide groove 215, so that the two door guide rails are connected.

[0027] Example 2, see Figures 1-6Based on the first embodiment, the spraying device 3 includes a protective agent tank 31, which is fixedly connected to the top of the first hydraulic chamber 23. The top of the electric slider 21 is fixedly connected to the sixth hydraulic chamber 32. One end of the sixth hydraulic chamber 32 is piston-slidingly connected to the seventh hydraulic rod 33. The seventh hydraulic rod 33 is fixedly connected to the top of the connecting rod 210. Through hydraulic transmission, the protective agent is stored, transported, and sprayed, ensuring uniform spraying of the welding protective agent during welding and effectively preventing welding defects. The protective agent tank 31 is fixedly connected to the top of the first hydraulic chamber 23 and is used to store the welding protective agent. The top of the electric slider 21 is fixedly connected to the sixth hydraulic chamber 32. One end of the sixth hydraulic chamber 32 is piston-slidingly connected to the seventh hydraulic rod 33. The seventh hydraulic rod 33 is fixedly connected to the top of the connecting rod 210. When the protective agent needs to be sprayed, hydraulic oil enters the sixth hydraulic chamber 32, pushing the seventh hydraulic rod 33 up and down, which in turn drives the connecting rod 210 up and down. The movement of the connecting rod 210 can control the opening and closing or position adjustment of the nozzle in the spraying device 3, so that the protective agent can be accurately sprayed on the welding area. At the same time, the protective agent tank 31 and the spraying device 3 are connected by a pipeline to ensure smooth delivery of the protective agent. The top of the second clamping block 27 is fixedly connected to the seventh hydraulic chamber 34. The piston at one end of the seventh hydraulic chamber 34 is slidably connected to the rack 35. The sixth hydraulic chamber 32 and the seventh hydraulic chamber 34 are connected by a connecting hose. The top of the second clamping block 27 is fixedly connected to the seventh hydraulic chamber 34. The piston at one end of the seventh hydraulic chamber 34 is slidably connected to the rack 35. The sixth hydraulic chamber 32 and the seventh hydraulic chamber 34 are connected by a connecting hose, allowing hydraulic oil to flow between the two. When hydraulic oil enters the seventh hydraulic chamber 34, it pushes the rack 35 to move. The movement of the rack 35 can drive the movement of related components through gear transmission and other means. The movement of the seventh hydraulic rod 33 in the sixth hydraulic chamber 32 will also affect the pressure and flow of the hydraulic oil in the seventh hydraulic chamber 34, thereby coordinating the movement of various components and achieving precise control of the clamping block. A peristaltic pump body 36 is fixedly connected to the top of the second clamping block 27. A circular gear 37 is fixedly connected to the outer wall of the output end of the peristaltic pump body 36. The circular gear 37 and the rack 35 are intermeshed. A water pipe is fixedly connected between the peristaltic pump body 36 and the protective agent tank 31. The right side of the peristaltic pump body 36 is fixedly connected to the spray pipe.

[0028] When the above-mentioned equipment is in actual use, the connecting rod 210 rises to drive the seventh hydraulic rod 33 to rise. During the rising process of the seventh hydraulic rod 33, the internal pressure of the sixth hydraulic chamber 32 and the seventh hydraulic chamber 34 increases, driving the rack 35 to move to the left, and the rack 35 drives the circular gear 37 to rotate. The circular gear 37 drives the output end of the peristaltic pump body 36 to rotate, and water is drawn from the inside of the protective agent box 31 through a water pipe, and the protective agent is sprayed on the end where the door guide rail intersects through the spray pipe to prevent oxidation during welding.

[0029] Example 3, see Figure 1-Figure 7Based on the first embodiment, the fixing device 4 includes an eighth hydraulic chamber 41, which is fixedly connected to the inner wall of the first clamping block 25. An eighth hydraulic rod 42 is slidably connected to one end of the eighth hydraulic chamber 41 by a piston. An airbag 43 is mounted on the right side of the eighth hydraulic chamber 41 and is in communication with the eighth hydraulic chamber 41. Through the cooperation of hydraulic transmission and airbag 43, the recessed portion of the door guide rail is fixed, enhancing the stability of the welding process and preventing weld quality problems caused by guide rail deformation or movement. The eighth hydraulic chamber 41 is fixedly connected to the inner wall of the first clamping block 25. An eighth hydraulic rod 42 is slidably connected to one end of the eighth hydraulic chamber 41 by a piston. An airbag 43 is mounted on the right side of the eighth hydraulic chamber 41 and is in communication with the eighth hydraulic chamber 41. When the recessed portion of the guide rail needs to be fixed, hydraulic oil enters the eighth hydraulic chamber 41, pushing the eighth hydraulic rod 42 out. The extended eighth hydraulic rod 42 can then press against the recessed portion of the guide rail, securing it in place. At the same time, the airbag 43 is connected to the eighth hydraulic tank 41, and the pressure changes of the hydraulic oil will be transmitted to the airbag 43, causing the airbag 43 to expand or contract. The expansion of the airbag 43 can further increase the fixing force of the guide rail, ensuring that the guide rail remains stable during the welding process, and avoiding displacement or deformation of the guide rail due to vibration or external force.

[0030] When the above-mentioned equipment is used, when the door guide rail is clamped by the first clamping block 25, the door guide rail squeezes the eighth hydraulic rod 42, and the eighth hydraulic rod 42 moves sideways. The internal pressure of the eighth hydraulic chamber 41 increases, driving the airbag 43 to expand, so that the airbag 43 fixes the groove of the door guide rail, further improving the clamping of the door guide rail.

[0031] When the above-mentioned device is used in a specific manner, the above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the scope of protection of the present invention.
