Description

Technical Field

[0001] This utility model relates to the field of electric welding processing technology in automobile manufacturing, specifically an auxiliary device for automobile manufacturing. Background Technology

[0002] Automobiles are composed of numerous parts, and welding is one of the key processes in the production of these parts. To ensure the dimensions of the welded parts, improve assembly accuracy and efficiency, and prevent welding deformation, fixtures are used to hold the workpiece in place, thus assisting in the welding process.

[0003] Most auxiliary devices currently in use cannot position the workpiece. During use, if the workpiece cannot be positioned, its placement will be off-center. Manual placement of the workpiece on the specific workbench is impossible, leading to deviations in its subsequent welding position and hindering the achievement of design requirements. This affects the overall assembly accuracy and quality of the vehicle. Furthermore, inaccurate workpiece positioning requires workers to spend extra time and effort adjusting the workpiece position, increasing the difficulty and time of welding operations and resulting in low production efficiency. The positioning accuracy, working effect, and efficiency of this auxiliary device are poor. Moreover, it cannot prevent workpiece slippage during clamping. If the surface of the clamping plate is too smooth, the workpiece may deviate under external force when clamped, causing the workpiece to shift and resulting in machining failure. This also indicates poor clamping stability of the auxiliary device. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for electric welding in automobile manufacturing, so as to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for electric welding processing in automobile manufacturing, comprising a worktable, a positioning mechanism provided inside the worktable, the positioning mechanism including a through hole, a through hole opened on the top of the worktable, a motor bracket fixedly connected to one side of the worktable, a motor fixedly connected to the inner side of the motor bracket, a motor shaft fixedly connected to the output shaft of the motor via a coupling, the outer wall of the motor shaft being connected through to one side of the worktable, a gear fixedly connected to one end of the motor shaft, a rack meshing with the outer wall of the gear, a lifting block fixedly connected to one side of the rack, and a positioning rod fixedly connected to the top of the lifting block.

[0006] As a preferred technical solution, the lifting block has a sliding groove inside, and a slide rail is fixedly connected inside the sliding groove.

[0007] As a preferred technical solution, the outer wall of the slide rail is slidably connected to a slider, and the two sides of the slider are fixedly connected to the inner wall of the worktable.

[0008] As a preferred technical solution, the shape and size of the through hole match the shape and size of the positioning rod, and the shape of the through hole is circular.

[0009] As a preferred technical solution, the motor bracket is L-shaped, and there are two motor brackets.

[0010] As a preferred technical solution, a support plate is fixedly connected to the top of the workbench, and the number of support plates is two.

[0011] As a preferred technical solution, an electric push rod is fixedly connected to one side of the support plate, and a clamping plate is fixedly connected to one end of the electric push rod.

[0012] As a preferred technical solution, an anti-slip pad is fixedly connected to one side of the clamping plate, and the shape and size of the anti-slip pad match the shape and size of the clamping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a positioning mechanism, can achieve the function of positioning the workpiece to a specific position. During use, the starting motor drives the positioning rod to rise, so that the positioning rod cooperates with the positioning hole on the workpiece to position the workpiece on a specific station on the worktable. This can avoid the workpiece being placed in a deviated position due to the inability to position the workpiece accurately. It is impossible to accurately place the workpiece on the specific station on the worktable manually, which will cause the subsequent electric welding processing to be deviated, making it difficult to meet the design requirements and affecting the overall assembly accuracy and quality of the automobile. Inaccurate workpiece positioning also requires the operator to spend extra time and effort to adjust the workpiece position, increasing the difficulty and time of the welding operation and resulting in low production efficiency. This auxiliary device ensures the positioning accuracy, working effect and working efficiency.

[0015] 2. By using an anti-slip pad, this utility model can prevent the workpiece from sliding when clamping. During use, the anti-slip pad prevents the workpiece from sliding, thus avoiding a situation where the surface of the clamping plate is too smooth due to the inability to prevent the workpiece from sliding during clamping. This would cause the workpiece to deviate under the action of external force when the clamping plate clamps the workpiece, resulting in a shift in the workpiece's processing position and causing the workpiece to fail to process. This ensures the clamping stability of the auxiliary device. Attached Figure Description

[0021] 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.

[0022] Example: Figure 1 As shown, the present invention provides the following technical solution, including a workbench 1, a positioning mechanism 2 is provided inside the workbench 1, a support plate 4 is fixedly connected to the top of the workbench 1, there are two support plates 4, an electric push rod 5 is fixedly connected to one side of the support plate 4, a clamping plate 6 is fixedly connected to one end of the electric push rod 5, and an anti-slip pad 3 is fixedly connected to one side of the clamping plate 6.

[0023] When this auxiliary device is needed, the workpiece must first be positioned on a specific station of the workbench 1. The positioning mechanism 2 is used to position the workpiece on the specific station of the workbench 1. Then, two electric push rods 5 are activated simultaneously to extend the electric push rods 5. The electric push rods 5 drive the clamping plates 6 to move, so that the two clamping plates 6 clamp and fix the workpiece. After clamping and fixing, the positioning mechanism 2 retracts the positioning rod 211 into the workbench 1 so that the positioning rod 211 will not affect the subsequent work. When clamping and fixing the workpiece, the anti-slip pad 3 ensures that the workpiece will not slide when clamped, making the clamping plates 6 clamp more secure, thus completing the work.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, a positioning mechanism 2 is provided inside the workbench 1. The positioning mechanism 2 includes a through hole 201. A through hole 201 is opened on the top of the workbench 1. A motor bracket 202 is fixedly connected to one side of the workbench 1. A motor 203 is fixedly connected to the inner side of the motor bracket 202. The output shaft of the motor 203 is fixedly connected to a motor shaft 204 through a coupling. The outer wall of the motor shaft 204 is connected through to one side of the workbench 1. A gear 205 is fixedly connected to one end of the motor shaft 204. A rack 206 meshes with the outer wall of the gear 205. A lifting block 207 is fixedly connected to one side, and a positioning rod 211 is fixedly connected to the top of the lifting block 207. A sliding groove 208 is opened inside the lifting block 207, and a slide rail 209 is fixedly connected inside the sliding groove 208. A slider 210 is slidably connected to the outer wall of the slide rail 209. The two sides of the slider 210 are fixedly connected to the inner wall of the worktable 1. The shape and size of the through hole 201 match the shape and size of the positioning rod 211, and the through hole 201 is circular. The motor bracket 202 is L-shaped, and there are two motor brackets 202.

[0025] Specifically: When this auxiliary device is needed, the workpiece must first be positioned at a specific position on the worktable 1. At this time, the motor 203 is started, causing the motor shaft 204 to rotate. The motor shaft 204 drives the gear 205 to rotate. The gear 205, through the rack 206 on the lifting block 207, causes the lifting block 207 to rise. The lifting block 207 then causes the positioning rod 211 to rise. During the rising and falling of the positioning rod 211, the sliding of the slider 210 on the outer wall of the slide rail 209 makes the rising and falling of the positioning rod 211 more stable and smooth. The positioning rod 211 passes through the through hole 201 in the worktable 1 and rises above the worktable 1. Then, the positioning hole on the workpiece is inserted into the outer wall of the positioning rod 211 to position the workpiece, thus completing the positioning work.

[0026] like Figure 1 and Figure 4 As shown, an anti-slip pad 3 is fixedly connected to one side of the clamping plate 6, and the shape and size of the anti-slip pad 3 match the shape and size of the clamping plate 6.

[0027] Specifically, when clamping and fixing the workpiece, the anti-slip pad 3 ensures that the workpiece will not slide when clamped, making the clamping plate 6 clamp more securely, thus completing the anti-slip work.

[0028] The working principle of this utility model is as follows: When this auxiliary device is needed, the workpiece first needs to be positioned at a specific position on the worktable 1. At this time, the motor 203 is started, causing the motor 203 to drive the motor shaft 204 to start rotating. The motor shaft 204 drives the gear 205 to start rotating. The gear 205 drives the lifting block 207 to start rising through the rack 206 on the lifting block 207. The lifting block 207 drives the positioning rod 211 to start rising. During the lifting process of the positioning rod 211, the sliding of the slider 210 on the outer wall of the slide rail 209 makes the lifting of the positioning rod 211 more stable and smooth, allowing the positioning rod 211 to pass through the through hole in the worktable 1. 201. The motor rises above the worktable 1, and then the positioning hole on the workpiece is inserted into the outer wall of the positioning rod 211 to position the workpiece, thus completing the positioning work. Then, the two electric push rods 5 are started at the same time, causing the electric push rods 5 to extend. The electric push rods 5 drive the clamping plates 6 to move, so that the two clamping plates 6 clamp and fix the workpiece. After clamping and fixing, the motor 203 is started in reverse, so that the positioning rod 211 descends into the worktable 1, so that the positioning rod 211 will not affect the workpiece welding process. When the workpiece is clamped and fixed, the anti-slip pad 3 can ensure that the workpiece will not slide when clamped, making the clamping plates 6 clamp more secure, thus completing the anti-slip work.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
