Description

Technical Field

[0001] This utility model relates to the field of welding positioning technology, and in particular to a welding positioning fixture for bimetallic sheet assemblies. Background Technology

[0002] Bimetallic strip assemblies are an important structure of circuit breakers. A bimetallic strip assembly typically includes a bimetallic strip, a trigger element, and an adjustment mechanism. The bimetallic strip can deform when the tripping conditions are met (such as the current in the circuit reaching or exceeding the current threshold), and touch the triggering part of the trigger element, thereby triggering the trigger element to trip and disconnect the circuit, achieving the purpose of protecting the circuit. However, during the manufacturing process, bimetallic strip assemblies need to be welded using a welding machine. Traditional bimetallic component welding positioning fixtures have some drawbacks. When welding bimetallic components, the worktable needs to be rotated to facilitate welding requirements. However, after rotation, there is often a lack of a device to limit the positioning of the worktable, which can easily cause the bimetallic components to shake during welding, resulting in poor welding quality. Utility Model Content

[0003] The main purpose of this utility model is to provide a welding and positioning fixture for bimetallic sheet components, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A welding positioning fixture for bimetallic sheet assemblies includes a welding chamber and a welding machine. A workbench positioning auxiliary mechanism is provided at the bottom inner side of the welding chamber. The workbench positioning auxiliary mechanism includes a rotating platform movably connected to the bottom inner side of the welding chamber, extending through the interior of the welding chamber. The rotating platform is movably installed inside the welding chamber. A support frame is fixedly connected to the upper end of the rotating platform. An operating table is fixedly connected to the upper end of the support frame. A placement frame is fixedly connected to the outer side of the operating table. A fixing ring is fixedly connected to the outer side of the support frame. A positioning block is fixedly connected to the outer side of the fixing ring. A docking chamber is slidably connected to the outer side of the positioning block. A support block is fixedly connected to the lower end of the docking chamber. An adjustment groove is formed inside the positioning block. A baffle is fixedly connected to the inner side of the adjustment groove. A spring block is fixedly connected to the upper end of the baffle. A positioning head is fixedly connected to the upper end of the spring block.

[0005] Preferably, a large gear is fixedly connected to the lower end of the rotating table, a mounting frame is fixedly connected to the lower end of the welding chamber, a motor is fixedly connected to the inner side of the mounting frame, and a small gear is installed on the upper end of the motor.

[0006] Preferably, there are multiple sets of the placement racks, the lower end of the support block is fixedly connected to the inner bottom of the welding chamber near the rotating table, the positioning head passes through the interior of the positioning block, and the positioning head is slidably connected to the positioning block.

[0007] Preferably, the positioning head extends into the interior of the docking chamber, the positioning head is movably connected to the docking chamber, and there are multiple sets of positioning blocks.

[0008] Preferably, the multiple sets of positioning blocks correspond sequentially to the multiple sets of placement frames, and one end of the small gear meshes with one end of the large gear.

[0009] Preferably, the welding machine is installed on the inner bottom of the welding chamber near the rear side of the rotating table. A support chamber is fixedly connected to the lower end of the welding chamber near the outer side of the mounting frame. A support leg is fixedly connected to the lower end of the support chamber. There are four sets of support legs.

[0010] Compared with the prior art, the present invention has the following beneficial effects: When the positioning head, which rotates with the rotary table, contacts the docking chamber, the docking chamber forces the positioning head to move into the control groove and compresses the spring block. As the rotary table continues to rotate, the positioning block moves to the middle position of the docking chamber. At this time, the spring block, under the action of elasticity, pushes the positioning head into the docking chamber and locks it in place. This process causes the rotary table to generate a damping effect during rotation, and finally achieves precise positioning and stopping. When the rotary table is in this positioning and stopping state, the welding operation of the bimetallic sheet assembly in the placement frame can effectively prevent the assembly from shifting due to vibration during the welding process.

[0013] 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.

[0014] like Figure 1-4 As shown, a welding positioning fixture for bimetallic sheet components includes a welding chamber 1 and a welding machine 2. A workbench positioning auxiliary mechanism 5 is provided at the bottom inner side of the welding chamber 1. The workbench positioning auxiliary mechanism 5 includes a rotating platform 51 movably connected to the bottom inner side of the welding chamber 1. The rotating platform 51 penetrates the interior of the welding chamber 1 and is movably installed inside the welding chamber 1. A support frame 52 is fixedly connected to the upper end of the rotating platform 51. An operating table 53 is fixedly connected to the upper end of the support frame 52. A placement frame 54 is fixedly connected to the outer side of the operating table 53. A fixing ring 55 is fixedly connected to the outer side of the support frame 52. A positioning block 56 is fixedly connected to the outer side of the fixing ring 55. A docking chamber 57 is slidably connected to the outer side of the positioning block 56. A support block 58 is fixedly connected to the lower end of the docking chamber 57. An adjustment groove 59 is opened inside the positioning block 56. A baffle 510 is fixedly connected to the inner side of the adjustment groove 59. A spring block 511 is fixedly connected to the upper end of the baffle 510. A positioning head 512 is fixedly connected to the upper end of the spring block 511.

[0015] In this embodiment, a large gear 513 is fixedly connected to the lower end of the rotating table 51, a mounting frame 514 is fixedly connected to the lower end of the welding chamber 1, a motor 515 is fixedly connected to the inner side of the mounting frame 514, a small gear 516 is installed on the upper end of the motor 515, there are multiple sets of placement frames 54, the lower end of the support block 58 is fixedly connected to the inner bottom of the welding chamber 1 near the rotating table 51, the positioning head 512 penetrates the interior of the positioning block 56, the positioning head 512 is slidably connected to the positioning block 56, the positioning head 512 extends into the interior of the docking chamber 57, the positioning head 512 is movably connected to the docking chamber 57, there are multiple sets of positioning blocks 56, and multiple sets of positioning blocks 56 correspond sequentially to multiple sets of placement frames 54, one end of the small gear 516 meshes with one end of the large gear 513.

[0016] Specifically, the worker first places multiple sets of bimetallic strip assemblies sequentially in the placement rack 54, and then rotates the placement rack 54 and the fixing ring 55 along with the support frame 52. This causes the fixing ring 55 to move the positioning block 56 into the docking chamber 57. When the positioning block 56 just contacts the docking chamber 57, the positioning head 512 contacts the docking chamber 57, causing the docking chamber 57 to push the positioning head 512 into the regulating groove 59 and compress the spring block 511. When the positioning block 56 moves to the middle of the docking chamber 57, the spring block 511, under the action of elasticity, pushes the positioning head 512 upward, causing the positioning head 512 to be stuck in the docking chamber 57. This causes the rotating table 51 to encounter damping during rotation, and at the same time, the motor 515 is turned off, allowing one set of placement racks 54 to rotate. 4 corresponds to the docking chamber 57, which positions the bimetallic strip assembly in the placement frame 54. When the positioning head 512, which rotates with the rotating table 51, contacts the docking chamber 57, the docking chamber 57 forces the positioning head 512 to move into the regulating groove 59 and compress the spring block 511. As the rotating table 51 continues to rotate, the positioning block 56 moves to the middle position of the docking chamber 57. At this time, the spring block 511, under the action of elasticity, pushes the positioning head 512 into the docking chamber 57 and locks it. This process causes the rotating table 51 to generate a damping effect during rotation, and finally achieves precise positioning and stopping. When the rotating table 51 is in this positioning and stopping state, the welding operation of the bimetallic strip assembly in the placement frame 54 can be performed, which can effectively prevent the assembly from shifting due to vibration during the welding process.

[0017] In this embodiment, the welding machine 2 is installed on the inner bottom of the welding chamber 1 near the rear side of the rotating table 51. The lower end of the welding chamber 1 is fixedly connected to the outer side of the mounting frame 514. The lower end of the support chamber 3 is fixedly connected to the support leg 4. There are four sets of support legs 4.

[0018] Specifically, starting the motor 515 causes the small gear 516 to rotate, which in turn causes the small gear 516 to rotate the large gear 513, which in turn causes the turntable 51 to rotate the support frame 52. Then, starting the welding machine 2 causes the welding machine 2 to weld the positioned bimetallic sheet assembly.

[0019] Working principle: During welding, the worker first places multiple sets of bimetallic strip assemblies sequentially in the placement rack 54, then starts the motor 515. The motor 515 drives the pinion 516 to rotate, which in turn drives the gear 513 to rotate. This causes the rotating table 51 to rotate the support frame 52, and the placement rack 54 and fixing ring 55 rotate along with the support frame 52. The fixing ring 55 then moves the positioning block 56 into the docking chamber 57. Just as the positioning block 56 contacts the docking chamber 57, the positioning head 512 contacts the docking chamber 57, causing the docking chamber 57 to push the positioning head 512 into the regulating groove 59. This also causes the positioning head 512 to compress the spring block 511. When the positioning block 56 reaches the center of the docking chamber 57, the spring block 511, under its elastic force, pushes the positioning head 512 upwards, locking it inside the docking chamber 57. This causes the rotating table 51 to encounter damping during rotation, and simultaneously... When machine 515 is shut down, one set of placement racks 54 is aligned with docking chamber 57, thus positioning the bimetallic strip assembly within the placement rack 54. Then, welding machine 2 is started, and welding machine 2 welds the positioned bimetallic strip assembly. When the positioning head 512, which rotates with the rotating table 51, contacts the docking chamber 57, the docking chamber 57 forces the positioning head 512 to move into the regulating groove 59 and compress the spring block 511. As the rotating table 51 continues to rotate, the positioning block 56 moves to the middle position of the docking chamber 57. At this time, the spring block 511, under the action of elasticity, pushes the positioning head 512 into the docking chamber 57 and locks it. This process causes the rotating table 51 to generate a damping effect during rotation, and finally achieves precise positioning and stopping. When the rotating table 51 is in this positioning and stopping state, the welding operation of the bimetallic strip assembly within the placement rack 54 can effectively prevent the assembly from shifting due to vibration during the welding process.
