Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding carriers, in particular to an assembly positioning welding carrier. BACKGROUND

[0002] A welding carrier is a special tooling equipment used to fix, position and support workpieces, mainly to ensure accurate positioning of parts during welding, reduce deformation and improve production efficiency. It stabilizes the workpiece through mechanical, pneumatic or magnetic clamping, etc. It is suitable for automobile manufacturing, aerospace, electronics and steel structure industries, especially for mass production and automated welding (such as robot welding). When designing, the shape of the workpiece, welding heat affected zone and high temperature resistant materials should be considered to achieve high precision, standardization and stable welding quality.

[0003] The existing Chinese patent with publication number CN212122183U discloses a welding carrier, which includes a carrier plate, a pressing plate, a push block and two movable blocks. The pressing plate is used to press the workpiece tightly on the carrier plate. The two movable blocks are arranged on both sides of the push block and in contact with the side surface of the push block. The push block has a first segment, a second segment and a middle segment located between the first segment and the second segment. The width of the first segment is smaller than that of the second segment. The middle segment has a limiting slot on each side. The distance between the two limiting slots is greater than the width of the first segment.

[0004] In related technologies, by moving the push block, the movable blocks are in contact with the first segment or the limiting slot of the push block, which can drive the two movable blocks to move synchronously to clamp or release the workpiece. After the movable blocks clamp the workpiece, the welding equipment welds the workpiece. After welding is completed, the movable blocks release the workpiece.

[0005] According to the related technologies in the above, the inventors believe that during the welding process, only single operation cycle can be achieved, lacking continuous positioning and holding capability, resulting in repeated clamping during multi-welding point operation, affecting the welding efficiency of the workpiece. UTILITY MODEL CONTENT

[0006] The technical problem to be solved by the utility model is to provide an assembly positioning welding carrier, which solves the technical problem that only single operation cycle can be achieved during the welding process, lacking continuous positioning and holding capability, resulting in repeated clamping during multi-welding point operation, affecting the welding efficiency of the workpiece.

[0007] To achieve the above purpose, the utility model provides the following technical scheme:

[0008] Assemble the positioning welding carrier, including: rack, for supporting the welding carrier; first welding module, installed on the rack, the first welding module positions the workpiece, so that the workpiece can be initially positioned and complete the first welding stage; second welding module, installed on the rack, the second welding module positions the workpiece, so that the workpiece can be positioned twice and complete the second welding stage; switching assembly, installed on the rack, the switching assembly is used to switch the first welding stage and the second welding stage.

[0009] Further, the first welding module is formed with a positioning groove, and the first welding module is formed with a guide slope, which is inclined towards the side close to the positioning groove.

[0010] Further, the second welding module is formed with a mounting groove, the second welding module is provided with a fixing rod, the fixing rod is provided with a fixing bolt, the fixing bolt is threadedly connected on the fixing rod, and one end of the fixing bolt extends towards the side close to the mounting groove.

[0011] Further, the rack is provided with a sliding block, the sliding block is slidingly installed on the rack, the second welding module is installed on the sliding block, and the sliding block slides towards or away from the side of the first welding module.

[0012] Further, the rack is provided with a reset spring, the reset spring abuts between the sliding block and the rack.

[0013] Further, the first welding module is provided with a support rod relative to one side of the second welding module, one end of the support rod is slidingly installed on the rack, and the other end extends towards the side close to the first welding module.

[0014] Further, a support spring is arranged between the rack and the support rod, and the support spring abuts between the rack and the support rod.

[0015] In summary, the present application has the following technical effects of assembling the positioning welding carrier:

[0016] In use, two workpieces to be welded are placed on the first welding module for positioning, and the workpieces to be welded in the second step are placed on the second welding module. When the welding equipment completes the welding of the workpieces on the first welding module, the switching assembly switches the first welding stage and the second welding stage. Then the welding equipment welds the workpieces on the second welding module, so that the welding carrier can realize multiple welding operations, maintain the stability of the workpiece positioning, and improve the welding efficiency of the workpiece without repeated clamping during multiple welding point operations.

[0017] The positioning groove and guide slope on the first welding module, as well as the fixing rod and fixing bolt on the second welding module, improve the stability of the workpiece during installation.

[0018] By mounting the second welding module on the slider, and with the return spring pressed against the frame and the slider, the accuracy of the workpiece position on the second welding module is improved through the setting of the support rod and the support spring.

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0026] This application discloses an assembly positioning welding carrier.

[0027] Reference Figure 1 The assembly and positioning welding carrier includes a frame 1, on which a first welding module 2 and a second welding module 3 are mounted. The welding equipment completes the first welding stage on the first welding module 2 and the second welding stage on the second welding module 3. A switching component 4 is mounted on the frame 1. After the first welding stage is completed, the switching component 4 switches the first welding stage to the second welding stage, and the external welding equipment then welds the workpiece on the second welding module 3.

[0028] The first welding module 2 is arranged in several groups at intervals on the frame 1. In use, the number of workpieces to be welded depends on the needs of the first welding stage, and then several groups of the first welding module 2 are selected. Preferably, in this application, the first welding module 2 is arranged in three groups at intervals on the frame 1. In use, the three groups of workpieces are placed on the first welding module 2 respectively, and the external welding equipment welds the three groups of workpieces.

[0029] Reference Figures 2-3 To improve the stability of the workpiece placed on the first welding module 2, a positioning groove 21 is provided on the first welding module 2. Furthermore, a guide slope 22 is formed on the first welding module 2, which is inclined towards the inner side near the positioning groove 21. When placing the workpiece, the guide slope 22 guides the workpiece, and then the workpiece is placed into the positioning groove 21 of the first welding module 2. After the workpiece is placed, external welding equipment welds the workpiece, completing the first welding stage.

[0030] Reference Figure 4 The second welding module 3 has a mounting groove 31, and the workpiece is placed in the mounting groove 31. To improve the stability of the workpiece on the second welding module 3, the second welding module 3 is provided with a fixing rod 32, and a fixing bolt 321 is threaded onto the fixing rod 32. One end of the fixing bolt 321 extends towards the side close to the mounting groove 31. When the workpiece is placed in the mounting groove 31 of the second welding module 3, rotating the fixing bolt 321 causes one end of the fixing bolt 321 to press against the workpiece, thereby improving the stability of the fixing bolt 321 on the second welding module 3.

[0031] In use, to improve the ease of switching the second welding module 3 on the frame 1, the switching component 4 includes a slider 41, which slides on the frame 1 towards or away from the first welding module 2. The second welding module 3 is mounted on the slider 41. Furthermore, a return spring 42 is provided between the slider 41 and the frame 1, pressing against the frame 1 and the slider 41. In use, pushing the slider 41 towards the first welding module 2 compresses the return spring 42. After the workpiece welding is completed, the slider 41 moves away from the first welding module 2 under the action of the return spring 42, allowing the workpiece to be removed after welding.

[0032] Furthermore, a support rod 43 is provided on one side of the first welding module 2 relative to the second welding module 3. The support rod 43 is horizontally positioned, with one end slidably mounted on the frame 1 and the other end extending towards the side closer to the first welding module 2. In use, the support rod 43 limits the position of the workpiece relative to the second welding module 3. Additionally, a support spring 44 is provided between the support rod 43 and the frame 1, pressing against the support rod 43 and the frame 1. In use, the support rod 43 positions the workpiece. When the support rod 43 presses against the workpiece, the support spring 44 compresses, pressing the workpiece against the second welding module 3. Initially, if the workpiece shifts from the second welding module 3, the support rod 43 adjusts the position of the workpiece, allowing it to be embedded in the mounting groove 31 of the second welding module 3. Simultaneously, the compression of the support spring 44 reduces the impact force of the workpiece striking the support rod 43.

[0033] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
