Description

Technical Field

[0001] This utility model relates to the field of welding positioning technology, and more specifically to a welding positioning device. Background Technology

[0002] With the progress of the times and the development of society, there are more and more types and appearances of automobiles. In order to assemble the car body-in-white, it is necessary to weld the various parts of the car together, such as welding the body-in-white to the doors and other parts. Welding equipment is required when welding the car body-in-white. At the same time, in order to prevent the body-in-white from shifting during welding, it is necessary to position and clamp the body-in-white to improve the welding accuracy.

[0003] For example, a positioning fixture for welding a body-in-white, with prior art announcement number CN218109834U, uses a hand lever to move an adjusting seat, thereby rotating an adjusting rod and moving a sliding sleeve to change the distance between the second fixing plate and the first fixing plate. This allows for accurate positioning and clamping of the body-in-white during welding, ensuring that the body-in-white does not shift during welding and guaranteeing the quality of the welding.

[0004] However, the above-mentioned existing technologies still have the following problems when used: During the welding process of the body-in-white, welding will generate instantaneous high temperature. The body-in-white and components are exposed to the high temperature environment of welding for a long time, which is prone to thermal deformation. This requires frequent shutdowns for maintenance and replacement of damaged parts, which not only increases equipment maintenance costs, but also interrupts the production process and reduces overall production efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a welding positioning device that actively dissipates heat through a heat dissipation component. This can effectively reduce the thermal deformation of components and welding frames caused by high welding temperatures, improve the ambient temperature of the working area, and enhance operational comfort. Furthermore, the height and horizontal position of the electric fan can be adjusted, making heat dissipation more targeted, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding positioning device, comprising a base, two symmetrically distributed movable blocks on the top of the base, each movable block having a base plate on its top, the base plate being connected to the movable blocks via a rotating assembly, welding frames mounted on the top of each of the two base plates, and multiple evenly distributed positioning clamps and positioning components fixed on the side of each welding frame that is close to each other, and a heat dissipation assembly on the top of each of the two base plates, the heat dissipation assembly comprising a hollow cylinder, a sliding groove on the top of each of the two base plates, the hollow cylinder being slidably disposed within the sliding groove, a vertical rod inside the hollow cylinder, and an electric fan fixedly mounted at the top of the vertical rod.

[0007] In a preferred embodiment, the top of the outer walls of both hollow cylinders are threaded with a first bolt, one end of which passes through the hollow cylinder and is fixed to the outer wall of the vertical rod. The top of both hollow cylinders are threaded with a second bolt, the bottom end of which passes through the hollow cylinder and is fixed to the top of the base plate.

[0008] In a preferred embodiment, multiple evenly distributed inserts are fixed at the bottom of both welding frames, and slots adapted to the inserts are opened at the top of both base plates. The inserts are inserted into the slots to improve the assembly efficiency of the welding frames and base plates.

[0009] In a preferred embodiment, each of the two movable blocks has a mounting slot on its top. The rotating assembly includes a motor installed inside the mounting slot. A gear is fixedly sleeved on the output shaft of the motor. The bottom of the base plate is connected to the mounting slot via a rotating shaft. An external gear ring that meshes with the gear is fixedly sleeved on the outer wall of each of the two rotating shafts. The base plate is rotated by the motor, which makes adjustment very quick and thus improves welding efficiency.

[0010] In a preferred embodiment, two symmetrically distributed protective shells are fixedly provided on the top of each of the two base plates, and both protective shells are located inside the sliding groove. An electric push rod is fixedly provided inside the protective shell, and a positioning block is fixedly provided at the bottom end of the piston rod of the electric push rod. A positioning groove adapted to the positioning block is opened on the top of each of the two moving blocks. The positioning block penetrates through the base plate and is inserted into the positioning groove. By using the positioning block and the positioning groove to connect, the stability between the base plate and the moving block can be effectively improved.

[0011] In a preferred embodiment, a groove is provided at the center of the top of the base, and two symmetrically distributed linear modules are fixed inside the groove. The sliders of the two linear modules are respectively fixed to the bottom of two moving blocks. The linear modules drive the moving blocks to move, thereby improving welding efficiency.

[0012] In a preferred embodiment, baffles are fixedly provided on the opposite side of the two movable blocks. The baffles are located at the top of the groove and move together with the movable blocks to cover the groove and prevent operators from accidentally stepping into the groove and getting injured.

[0013] In a preferred embodiment, slide rails are fixedly provided on both the front and rear sides of the top of the base, and slide blocks adapted to the slide rails are fixedly embedded on both the front and rear sides of the bottom of the two movable blocks. The slide blocks are slidably connected to the slide rails. By using the cooperation between the slide blocks and the slide rails, the stability of the movable blocks during movement can be improved.

[0014] The technical effects and advantages of this utility model are as follows: This utility model uses a heat dissipation component to actively deliver air for heat dissipation, which can effectively reduce the thermal deformation of components and welding frames caused by high welding temperatures, improve the ambient temperature of the work area, and enhance operational comfort. In addition, the height and horizontal position of the electric fan can be adjusted, making heat dissipation more targeted. In addition, the linear module and rotating assembly can automatically adjust the horizontal position and rotation angle of the parts, which facilitates rapid material loading and replacement and maintenance of the welding frame, significantly enhancing the versatility of the equipment and welding efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Refer to the instruction manual appendix Figures 1-6This utility model provides a welding positioning device, including a base 1. The top of the base 1 is provided with two symmetrically distributed moving blocks 2. The top of each moving block 2 is provided with a base plate 3. The base plate 3 is connected to the moving blocks 2 through a rotating component 4. The top of each base plate 3 is equipped with a welding frame 5. On the side of the two welding frames 5 that are close to each other, a plurality of evenly distributed positioning clamps 6 and positioning parts 7 are fixedly provided.

[0019] Both base plates 3 are equipped with heat dissipation components 8 on their tops. Each heat dissipation component 8 includes a hollow cylinder 81. Both base plates 3 have a sliding groove 82 on their tops. The hollow cylinder 81 is slidably disposed in the sliding groove 82. A vertical rod 83 is provided inside the hollow cylinder 81. An electric fan 84 is fixedly mounted on the top of the vertical rod 83. The electric fan 84 can be a rotating oscillating type to facilitate further adjustment of the airflow direction. Since this is a well-known existing technology, it will not be described in detail here.

[0020] Furthermore, a first bolt 85 is threadedly connected to the top of the outer wall of each of the two hollow cylinders 81. One end of the first bolt 85 passes through the hollow cylinder 81 and is fixed to the outer wall of the vertical rod 83. A second bolt 86 is threadedly connected to the top of each of the two hollow cylinders 81. The bottom end of the second bolt 86 passes through the hollow cylinder 81 and is fixed to the top of the base plate 3. After the first bolt 85 is tightened, the bolt end abuts against the vertical rod 83, restricting its up and down movement, which makes it easy for the operator to quickly adjust the height of the electric fan 84. The second bolt 86 is tightened to abut against the top of the base plate 3, which makes it easy to adjust the position of the hollow cylinder 81.

[0021] Both moving blocks 2 have mounting slots 11 on their tops. The rotating assembly 4 includes a motor 41 installed inside the mounting slot 11. A gear 42 is fixedly fitted on the output shaft of the motor 41. The bottom of the base plate 3 is connected to the mounting slot 11 via a rotating shaft 43. Both rotating shafts 43 have external gear rings 44 fixedly fitted on their outer walls to mesh with the gear 42. The motor 41 can be a servo motor, which has a built-in encoder to provide real-time position feedback. The controller adjusts according to the feedback to ensure accurate arrival at the target. Since this is a well-known existing technology, it will not be described in detail here.

[0022] The base 1 has a groove 16 at the center of its top. Two symmetrically distributed linear modules 17 are fixed inside the groove 16. The sliders of the two linear modules 17 are fixed to the bottom of the two moving blocks 2 respectively. The base 1 has slide rails 19 fixed on both the front and rear sides of its top. The two moving blocks 2 have slide seats 20 that are adapted to the slide rails 19 fixed on both the front and rear sides of their bottoms. The slide seats 20 are slidably connected to the slide rails 19.

[0023] In actual welding operations, the component to be welded is first placed on the welding frame 5 and fixed by the positioning clamp 6 and positioning piece 7. Then, the motor 41 drives the rotating shaft 43 to rotate the base plate 3 180° through the gear 42 and the external gear ring 44, so that the component is turned towards the body-in-white. Next, the linear module 17 pushes the moving block 2 and the component on the welding frame 5 towards the body-in-white until they are precisely positioned and fit against the body-in-white. After alignment, welding can be carried out. During the welding process, the operator can adjust the direction of the electric fan 84 to blow air for heat dissipation, which can reduce the impact of high welding temperature on the thermal deformation of the welding frame 5 and improve the working environment by cooling it down. In addition, the operator can also move the electric fan 84 back and forth along the base plate 3 and adjust the extension length of the vertical rod 83 extending out of the hollow cylinder 81 to change the height of the fan, thereby flexibly adapting to different working conditions and improving the convenience of operation.

[0024] Refer to the instruction manual appendix Figure 2 and Figure 3 Both welding frames 5 have multiple evenly distributed inserts 9 fixed at their bottoms, and both base plates 3 have slots 10 on their tops that are adapted to the inserts 9. The inserts 9 are inserted into the slots 10.

[0025] After the welding work is completed, the operator can rotate the base plate 3 180° using the rotating component 4 to replace parts and inspect or replace the positioning fixture 6 and positioning component 7. In addition, the entire welding frame 5 can be removed from the base plate 3 and replaced with a special welding frame 5 adapted to different body-in-white parts, thereby enhancing the versatility of the equipment, simplifying the replacement process, and effectively improving the efficiency of welding operations. When installing the welding frame 5, the operator can quickly position and install it by inserting the plug 9 into the slot 10 on the base plate 3, further improving the efficiency of welding production.

[0026] To improve the stability of base plate 3, such as Figure 1 and Figure 2 As shown, two symmetrically distributed protective shells 12 are fixed on the top of both base plates 3, and both protective shells 12 are located inside the sliding groove 82. An electric push rod 13 is fixed inside the protective shell 12. A positioning block 14 is fixed at the bottom end of the piston rod of the electric push rod 13. A positioning groove 15 that matches the positioning block 14 is opened on the top of both moving blocks 2. The positioning block 14 passes through the base plate 3 and is inserted into the positioning groove 15.

[0027] After the base plate completes a 180° rotation, the positioning blocks are driven downward by the electric push rods on both sides of the base plate. The positioning blocks then embed into the top positioning groove of the moving block, forming a rigid connection. This design, by strengthening the constraints of key nodes, fundamentally suppresses the slight displacement of the base plate and ensures that the welding positioning accuracy is not affected.

[0028] like Figure 1As shown, each of the two movable blocks 2 is fixedly equipped with a baffle 18 on a side away from each other. The baffle 18 is located on the top of the groove 16. The baffle 18 moves with the movable block 2 and can cover the groove 16 to prevent the operator from accidentally stepping into the groove 16 and getting injured.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
