Description

Technical Field

[0001] This application relates to the field of welding fixture technology, specifically a multi-station fixture for welding wires and cables. Background Technology

[0002] In the field of wire and cable welding, multi-station fixtures, with their ability to handle multiple welding tasks simultaneously, have become key equipment for improving production efficiency and welding accuracy. Through reasonable station layout and functional design, multi-station fixtures can achieve efficient positioning, fixing, and welding of wires and cables, playing an indispensable role in automated production lines and are widely used in various industries such as electronics and power.

[0003] However, after the existing multi-station fixture completes the welding operation, the products inside cannot be automatically detached. It is necessary to manually move the fixture to a specific ejection device and use external force to lift the products and other objects inside the fixture to separate them from the fixture. This method not only increases the labor intensity of the operators and extends the processing cycle, but the additional ejection device also occupies valuable production space. At the same time, it is very easy to damage the products when lifting them, resulting in a decrease in the product qualification rate and seriously restricting the overall efficiency and product quality of wire and cable welding processing. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a multi-station fixture for welding wires and cables, which enables automatic detachment of welded products, reduces manual intervention, lowers the labor intensity of operators, significantly reduces operation steps, shortens the processing cycle, and eliminates the need for additional ejection devices, thus saving production space and solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a multi-station fixture for welding wires and cables, comprising a platform, a first placement groove and a second placement groove on the upper side of the platform, a welding groove on the upper side of the platform, the inner wall of the platform communicating with the inner walls of the first and second placement grooves, an installation cavity on the inner side of the platform, a plurality of lifting assemblies on the inner side of the installation cavity, each lifting assembly comprising a base plate, a top column fixedly connected to the upper side of the base plate, the outer side of the top column inserted into the inner side of the platform, an arc-shaped block fixedly connected to the bottom surface of the base plate, a movable plate inserted into the inner side of the platform, a conical top block fixedly connected to the upper side of the movable plate, a connecting plate fixedly connected to one end of the movable plate, and a tensioning plate fixedly connected to the outer side of the connecting plate.

[0007] The above solution utilizes the first placement slot, the second placement slot, the welding slot, and their connecting structure on the upper side of the platform. Combined with the inner movable plate, the conical top block, and multiple sets of lifting components in the mounting cavity, the multi-station fixing and linkage ejection function of the workpiece is realized. After welding, the movable plate drives the conical top block to move, and the arc-shaped block can lift the top column to lift the product, realizing the automatic detachment of the welded product, reducing manual intervention, reducing the labor intensity of operators, and significantly reducing operation steps and shortening the processing cycle. It also eliminates the need for additional ejection devices, saving production space.

[0008] Furthermore, the bottom surface of the substrate is fixedly connected to four rectangular array of guide telescopic rods, and the outer side of the guide telescopic rods is fixedly connected to the inner side of the mounting cavity.

[0009] Through the above scheme, the guide telescopic rods with four rectangular arrays ensure that the base plate and top column always maintain vertical guidance during the operation, prevent lifting deviation, improve ejection stability, avoid workpiece deformation or positioning inaccuracy due to uneven force, and further improve the product qualification rate.

[0010] Furthermore, two symmetrical reset springs are fixedly connected to the bottom surface of the substrate, and the other end of the reset springs is fixedly connected to the inner wall of the mounting cavity.

[0011] The above solution utilizes a reset spring to allow the base plate and top post to quickly return to their original positions after ejection, thus shortening the jig reset time, ensuring smooth continuous operation, reducing mechanical wear, and extending the jig's service life.

[0012] Furthermore, the inner side of the second placement slot is fixedly connected with a plurality of second partitions arranged at equal intervals, and the inner side of the first placement slot is fixedly connected with a plurality of first partitions arranged at equal intervals.

[0013] Through the above scheme, the first and second partitions form a fixed structure for separating the products to be processed, avoiding mutual interference during welding, ensuring consistent spacing between weld points, improving welding accuracy and process reliability, and reducing the need for manual adjustments.

[0014] Furthermore, a maintenance plate is installed on the inner side of the mounting cavity. The shape of the maintenance plate is adapted to the inner wall of the mounting cavity. The maintenance plate and the platform are fixedly connected by bolts.

[0015] The above solution involves bolting the inspection plate to the platform, providing a modular inspection window for quick disassembly and maintenance of the lifting components and internal mechanisms, reducing equipment downtime, and accommodating the replacement of different specifications of ejection modules, thus enhancing the fixture's functional expandability.

[0016] Furthermore, an installation groove is provided on the outer side of the platform, and two insert blocks are inserted into the inner wall of the installation groove. A rotating shaft is rotatably connected between the two insert blocks. A flip plate is fixedly connected to the outer side of the rotating shaft, and multiple pressure blocks are fixedly connected to the outer side of the flip plate.

[0017] The above scheme, with the aforementioned insert block and rotating shaft, flap plate, and pressure block forming a flip-up auxiliary clamping structure, applies uniform pressure to the workpiece through the pressure block on the outside of the flap plate, preventing cable displacement during welding, ensuring the consistency of weld point positions, and the flip design facilitates quick clamping and release.

[0018] Furthermore, a magnet is fixedly installed on the inner side of the platform, the flip plate is made of steel, and the flip plate and the magnet are magnetically connected.

[0019] The above solution uses a magnetic connection between the flip plate and the inner side of the platform to achieve rapid positioning and fixation of the flip plate, simplifying the operation process. It also avoids the complexity of traditional mechanical locking mechanisms, reduces the failure rate, and improves the ease of operation of the fixture.

[0020] Furthermore, the top of the top post is covered with a rubber sleeve.

[0021] The above-mentioned solution, which uses a rubber sleeve covering the top of the ejector post, provides a flexible contact surface for the workpiece during ejection, preventing surface scratches or deformation caused by hard impacts. It is especially suitable for the protective ejection of precision electronic connectors, further ensuring the integrity of the product's appearance and function.

[0022] Beneficial effects

[0023] This multi-station fixture for welding wires and cables utilizes a first placement slot, a second placement slot, a welding slot, and their connecting structure on the upper side of the platform. Combined with an inner movable plate, a conical top block, and multiple sets of lifting components within the mounting cavity, it achieves multi-station fixing and linked ejection of the workpiece. After welding, the movable plate drives the conical top block to move, and the arc-shaped block can lift the top column to eject the product, achieving automatic detachment of the welded product. This reduces manual intervention and the labor intensity of operators. At the same time, this method can significantly reduce the number of operation steps and shorten the processing cycle. It also eliminates the need for additional ejection devices, saving production space. Attached Figure Description

[0033] Please see Figure 1 , Figure 2 and Figure 4A movable plate 7 is inserted into the inner side of the platform 1, and a conical top block 8 is fixedly connected to the upper side of the movable plate 7. The shape of the conical top block 8 is adapted to the shape of the arc block 603, so that the conical top block 8 can stably and smoothly push up the base plate 601 and the top column 604, thereby quickly lifting the product. A connecting plate 9 is fixedly connected to one end of the movable plate 7, and a pulling plate 10 is fixedly connected to the outer side of the connecting plate 9. The outer side of the pulling plate 10 is provided with anti-slip texture, which can further improve the anti-slip performance and make it more stable for the operator to pull.

[0036] This embodiment of a multi-station fixture for welding wires and cables utilizes a first placement groove 2, a second placement groove 3, a welding groove 4, and their connecting structures on the upper side of the platform 1. Combined with an inner movable plate 7, a conical top block 8, and multiple sets of lifting components 6 within the mounting cavity 5, it achieves multi-station fixing and linked ejection of the workpiece. After welding, the movable plate 7 drives the conical top block 8 to move, and the arc-shaped block 603 can lift the top column 604 to lift the product, achieving automatic detachment of the welded product. This reduces manual intervention and the labor intensity of operators. At the same time, this method can significantly reduce operation steps and shorten the processing cycle, and it does not require additional ejection devices, saving production space.

[0037] The working principle of the above embodiment is as follows: During the welding operation, the product to be processed is placed in the first placement groove 2 and the second placement groove 3, and is separated and positioned by the first partition 11 and the second partition 12. The welding operation is completed at the welding groove 4. After the processing is completed, the pulling plate 10 is manually pulled to drive the connecting plate 9 and the moving plate 7 to move, so that it drives the conical top block 8 to move laterally. At this time, the lateral movement of the conical top block 8 can push the arc block 603 to move upward. Then the arc block 603 can drive the base plate 601 and the top column 604 to move upward. At this time, the top column 604 is lifted upward to force the workpiece to leave the fixed position. During the lifting process, the guide telescopic rod 602 provides vertical guidance constraint to ensure stable movement. After that, the reset spring 605 elastically contracts after being ejected to reset the base plate 601. Then the rotating shaft 16 drives the flip plate 17 and the pressure block 18 to flip onto the surface of the platform 1. The magnetic attraction of the magnet 19 is used to fix the cable, thereby assisting in pressing the product. After that, when ejecting, the rubber sleeve at the top of the top column 604 flexibly contacts the surface of the workpiece to avoid hard damage.
