Description

Technical Field

[0001] This utility model relates to the field of sheet metal positioning technology, and in particular to a positioning and welding device for sheet metal parts of new energy vehicles. Background Technology

[0002] A positioning welding device is a piece of equipment or tool used to precisely position and fix a workpiece during the welding process. It can ensure that the workpiece maintains the correct position and posture during welding, reduce deviation and deformation, thereby improving welding quality and production efficiency.

[0003] The new energy vehicle sheet metal part positioning and welding device is a key piece of equipment specifically designed for the welding process of new energy vehicle sheet metal parts. It ensures the stability and reliability of the welding process and provides a solid and precise connection foundation for the body structure of new energy vehicles. In the past, the positioning and welding of automotive sheet metal parts was done manually by welders. Now, it is done mechanically by specialized automotive sheet metal part positioning and welding devices, thereby improving work quality. However, the existing positioning and welding devices for new energy vehicle sheet metal parts have a fixed positioning size. This means that each positioning and welding device can only position specific sheet metal parts and cannot be adapted to different sheet metal parts, resulting in insufficient versatility. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a positioning and welding device for sheet metal parts of new energy vehicles, which aims to improve the problem that each positioning and welding device in the prior art can only position specific sheet metal parts and cannot be adapted to different sheet metal parts, thus resulting in insufficient versatility.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a positioning and welding device for sheet metal parts of new energy vehicles, comprising a worktable, a rotating handle rotatably connected to the bottom of the worktable, two gears fixedly connected at equal intervals to the top of the outer wall of the rotating handle, multiple racks slidably connected at equal intervals to the inner side of the worktable, the multiple racks respectively meshing with the corresponding gears, a fixing plate fixedly connected to the end of each of the multiple racks, a positioning rod fixedly connected to the left and right sides of the top of each of the multiple fixing plates, multiple sliding grooves equally spaced on the top of the worktable, and a clamping and fixing mechanism installed on the top of each of the multiple positioning rods, the multiple clamping and fixing mechanisms being used to fix the sheet metal.

[0006] As a further description of the above technical solution:

[0007] The clamping and fixing mechanism includes a housing, and multiple housings are slidably connected to the outside of corresponding positioning rods. A rocker arm is rotatably connected to the left side of the outer wall of each of the multiple housings. A gear two is fixedly connected to the end of each of the multiple rocker arms. A gear three is rotatably connected to the right side of the inner side of each of the multiple housings. Each of the multiple gear threes meshes with a corresponding gear two. Multiple toothed grooves are equidistantly opened on adjacent sides of each of the multiple positioning rods. Pressure strips are fixedly connected to the left and right ends of adjacent sides of each of the multiple housings.

[0008] As a further description of the above technical solution:

[0009] Multiple anti-slip sleeves are equidistantly installed on the outer wall of the handle, and the left and right ends of the multiple anti-slip sleeves are fixedly connected with Velcro.

[0010] As a further description of the above technical solution:

[0011] Each of the rocker arms has a rubber sleeve fixedly connected to its outer wall, and each of the rubber sleeves has anti-slip texture on its outer wall.

[0012] As a further description of the above technical solution:

[0013] Each of the multiple positioning rods has a screw threaded to its top end, and each of the multiple screws has a limit plate threaded to its outer wall.

[0014] As a further description of the above technical solution:

[0015] The top of the outer wall of the workbench is equipped with screw two, and anti-collision strips are provided on the outer wall of each screw two.

[0016] As a further description of the above technical solution:

[0017] Support rods are fixedly connected to the four corners of the bottom of the workbench, and stabilizing frames are fixedly connected to the adjacent sides of the multiple support rods.

[0019] Each of the support rods has a protective sleeve slidably connected to its bottom, and each of the protective sleeves has a fixing ring fixedly connected to its outer wall.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, rotating the handle drives the gears to rotate. When the two gears rotate, they drive multiple racks to slide in opposite directions within the worktable. This, in turn, drives the corresponding positioning rods to move in opposite directions in cooperation with the corresponding sliding grooves through the fixing plates fixed at their ends, thereby achieving the positioning effect for different sheet metal parts.

[0022] 2. In this utility model, rotating the rocker arm drives the second gear to rotate on the outer shell. While the second gear rotates, it drives the third gear to rotate synchronously through meshing. When the second and third gears rotate synchronously, they mesh with the corresponding tooth grooves, thereby driving the outer shell to press down. In this way, the sheet metal parts are pressed down by the pressure strip fixed on the outer shell, thereby achieving the effect of fixing the sheet metal parts. Attached Figure Description

[0030] 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.

[0031] Reference Figure 2 and Figure 3This utility model provides an embodiment of a new energy vehicle sheet metal part positioning and welding device, including a workbench 1, a rotating handle 3 rotatably connected to the bottom of the workbench 1, two gears 4 fixedly connected at equal intervals to the top of the outer wall of the rotating handle 3, the rotating handle 3 drives the gears 4 to rotate, multiple racks 5 are slidably connected at equal intervals to the inner side of the workbench 1, the multiple racks 5 are respectively meshed with the corresponding gears 4, the ends of the multiple racks 5 are fixedly connected to the fixing plates 6, the top left and right sides of the multiple fixing plates 6 are fixedly connected to the positioning rods 7, the racks 5 drive the positioning rods 7 to move through the fixing plates 6, the top of the workbench 1 is provided with multiple sliding grooves 8 at equal intervals, the sliding grooves 8 are used to guide the movement trajectory of the positioning rods 7, the top of the multiple positioning rods 7 is installed with clamping and fixing mechanisms 2, the multiple clamping and fixing mechanisms 2 are used to fix the sheet metal, the outer wall of the rotating handle 3 is provided with multiple anti-slip sleeves 9 at equal intervals, the left and right ends of the multiple anti-slip sleeves 9 are fixedly connected with Velcro 10, the Velcro 10 is used to fix the anti-slip sleeves 9;

[0032] Specifically, rotating the handle 3 installed under the workbench 1 drives the two gears 4 fixed on it to rotate synchronously. When the two gears 4 rotate, they will drive multiple racks 5 to slide in opposite directions within the workbench 1 through meshing. Thus, the fixing plate 6 fixed at its end drives the corresponding positioning rod 7 to move in opposite directions with the cooperation of the corresponding slide groove 8. The anti-slip sleeve 9 fixed to the outside of the handle 3 by Velcro 10 can improve its grip.

[0033] Reference Figure 4 and Figure 5 The clamping and fixing mechanism 2 includes a housing 201. Multiple housings 201 are slidably connected to the outside of corresponding positioning rods 7. A rocker arm 202 is rotatably connected to the left side of the outer wall of each housing 201. A gear 203 is fixedly connected to the end of each rocker arm 202. A gear 204 is rotatably connected to the right inner side of each housing 201. Each gear 204 meshes with a corresponding gear 203. The rocker arm 202 drives the gear 204 to rotate synchronously through the gear 203. The adjacent positioning rods 7... Multiple toothed grooves 205 are evenly spaced on one side. Pressure strips 206 are fixedly connected to the left and right ends of adjacent sides of multiple outer shells 201. Pressure strips 206 are used to fix sheet metal parts. Rubber sleeves 11 are fixedly connected to the outer walls of multiple rocker arms 202. Anti-slip textures 12 are provided on the outer walls of multiple rubber sleeves 11. Anti-slip textures 12 are used to improve the grip of rubber sleeves 11. Screws 13 are threaded to the top of multiple positioning rods 7. Limiting pieces 14 are threaded to the outer walls of multiple screws 13. Screws 13 are used to fix limiting pieces 14.

[0034] Specifically, rotating multiple rocker arms 202 mounted outside the housing 201 drives the second gear 203 to rotate within the housing 201. Simultaneously, the second gear 203 rotates and meshes with the third gear 204. When the second gear 203 and the third gear 204 rotate synchronously, they mesh with the corresponding tooth grooves 205, thereby causing the housing 201 to press down. This presses down the sheet metal parts through the pressure strip 206 fixed on the housing 201. The rubber sleeve 11 fixed outside the rocker arm 202 improves the grip of the rocker arm 202 through the anti-slip texture 12. The limiting piece 14 fixed to the positioning rod 7 by the screw 13 prevents the clamping and fixing mechanism 2 from falling off.

[0035] Reference Figure 1 Screw 15 is installed on the top of the outer wall of the workbench 1. Anti-collision strips 16 are provided on the outer walls of the multiple screws 15. The screws 16 are used to fix the anti-collision strips 15. Support rods 17 are fixedly connected to the four corners of the bottom of the workbench 1. Stable frames 18 are fixedly connected to the adjacent side of the multiple support rods 17. Stable frames 18 are used to stabilize the support rods 17. Protective sleeves 19 are slidably connected to the bottom of the multiple support rods 17. Fixing rings 20 are fixedly connected to the outer walls of the multiple protective sleeves 19. Fixing rings 20 are used to fix the protective sleeves 19.

[0036] Specifically, the anti-collision strip 15, which is fixed by screw 16, can prevent workers from being bumped and injured. The stabilizer 18, which is used to connect multiple support rods 17, can improve the stability of the support rods 17. The protective sleeve 19, which is fixed to the support rods 17 by the fixing ring 20, can provide protection for the bottom of the support rods 17.

[0037] Working principle: When using the new energy vehicle sheet metal part positioning and welding device to fix different types of sheet metal parts, after placing the sheet metal parts on the worktable 1, rotate the handle 3 installed under the worktable 1. By rotating the handle 3, the two gears 4 fixed on it will rotate synchronously. When the two gears 4 rotate, they will drive multiple racks 5 to slide in opposite directions in the worktable 1 through meshing. Thus, the fixing plate 6 fixed at its end will drive the corresponding positioning rod 7 to move in opposite directions in cooperation with the corresponding slide groove 8, thereby achieving the positioning effect of different sheet metal parts.

[0038] After the sheet metal parts are positioned using the new energy vehicle sheet metal part positioning and welding device, multiple rocker arms 202 installed outside the housing 201 are rotated, thereby driving gear 203 to rotate within the housing 201. As gear 203 rotates, it drives gear 304 to rotate synchronously through meshing. When gear 203 and gear 304 rotate synchronously, they mesh with the corresponding tooth grooves 205, thereby causing the housing 201 to press down. In this way, the pressure strip 206 fixed on the housing 201 presses down on the sheet metal parts, thus achieving the effect of fixing the sheet metal parts.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
