Description

Technical Field

[0001] This application relates to the field of laser welding technology, and more specifically, to a laser welding fixture and laser welding equipment. Background Technology

[0002] Laser welding is a welding method that uses a focused laser beam as an energy source to bombard the workpiece and generate heat. Due to its advantages such as high precision, high efficiency, small heat-affected zone, and minimal deformation, laser welding has a promising future.

[0003] Laser welding fixtures are devices used to hold workpieces during laser welding. During welding, these fixtures are typically fixedly mounted on the base plate of the laser welding equipment. Current methods involve drilling bolt holes in both the base plate and the laser welding machine, and then fixing the fixture to the base plate using connecting bolts. This type of existing laser welding fixture has the following problems:

[0004] 1. Because of the bolted connection, the relative position of the laser welding fixture and the base plate is fixed. If different products need to be welded, the weld position of each product is different, which requires replacing the base plate or the laser welding fixture. It can be seen that this laser welding fixture has poor versatility and cannot be used to process multiple products at the same time.

[0005] 2. Bolted connections require tools for installation and disassembly, which is time-consuming and labor-intensive, affecting processing efficiency. Utility Model Content

[0006] The technical problem to be solved by the embodiments of this application is that the existing laser welding fixtures are fixed by bolts, which is inconvenient for loading and unloading.

[0007] To address the aforementioned technical problems, this application provides a laser welding fixture, which employs the following technical solution:

[0008] A laser welding fixture includes: a magnetic base, wherein the magnetic base is an electromagnet, and the magnetic base is externally connected to a power source, and the lower end surface of the magnetic base becomes magnetic after being energized;

[0009] A support frame, which is connected to the upper end face of the magnetic base;

[0010] A clamping seat is connected to the side of the support frame away from the magnetic base. The clamping seat is provided with a clamping block that extends out of the upper end face of the clamping seat. The clamping block is used to clamp the workpiece to be processed.

[0011] Furthermore, there are two of each of the support frame and clamping seat, and they are arranged in a one-to-one correspondence.

[0012] Furthermore, a gap is reserved between the two clamping seats.

[0013] Furthermore, each clamping seat is provided with a plurality of clamping blocks, and the plurality of clamping blocks are distributed at equal intervals on the clamping seat.

[0014] Furthermore, the clamping block is an electromagnet.

[0015] Furthermore, the support frame is provided with an adjustment component, which is connected to the clamping seat and is used to push the clamping seat to move up and down on the support frame.

[0016] Furthermore, the adjustment assembly includes a plurality of adjustment screws, which are threadedly connected to the support frame. One end of the adjustment screw extends out of the upper end face of the support frame, and the end of the adjustment screw extending out of the upper end face of the support frame abuts against the lower end face of the clamping seat.

[0017] Furthermore, each end of the support frame is provided with a lifting ring.

[0018] Furthermore, the support frame is provided with multiple weight-reducing perforated holes.

[0019] To address the aforementioned technical problems, this application also provides a laser welding device, which employs the following technical solution:

[0020] A laser welding device includes a base, a base plate and a laser welding head on the base, a laser welding fixture on the base plate, and the laser welding head for welding workpieces on the laser welding fixture. A magnetic base is magnetically connected to the base plate.

[0021] Compared with the prior art, the embodiments of this application have the following main advantages:

[0022] 1. This utility model uses an electromagnet as a magnetic base. By energizing the magnetic base, the laser welding fixture can be fixed to the base plate of the welding equipment. By de-energizing the magnetic base, the laser welding fixture can be moved freely from the base plate of the welding equipment. After moving it to the appropriate position, energizing the magnetic base again will fix the laser welding fixture in place. The laser welding fixture can be moved freely, thus adapting it to the product processing needs of different weld seam positions and improving its versatility.

[0023] 2. In this utility model, the magnetic base and the base plate of the welding equipment are fixed by magnetic attraction. The installation and disassembly of the laser welding fixture can be completed simply by turning the magnetic base on and off, without the need for any tools. This saves time in loading and unloading the laser welding fixture and improves processing efficiency. Attached Figure Description

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1:

[0035] like Figure 1-4 As shown, a laser welding fixture includes a magnetic base 1, a support frame 2, and a clamping seat 3. The magnetic base 1 is an electromagnet, and is externally powered. When energized, the lower surface of the magnetic base 1 becomes magnetic. By energizing the magnetic base 1, it becomes magnetic, allowing the laser welding fixture to be attracted and fixed to the base plate of the welding equipment. The support frame 2 is fixedly connected to the magnetic base 1 by screws. The support frame 2 is used to mount the clamping seat 3, enabling the clamping seat 3 to be connected and fixed to the magnetic base 1. The clamping seat 3 is fixedly connected to the side of the support frame 2 away from the magnetic base 1 by fixing screws 4. The clamping seat 3 is provided with a clamping block 5, which extends out of the upper surface of the clamping seat 3, and is used to clamp the workpiece to be processed.

[0036] Before processing, the magnetic base 1 is placed in the preset installation position on the base of the laser welding equipment. Then, the magnetic base 1 is powered by an external power supply, making the lower end face of the magnetic base 1 magnetic, thereby attracting and fixing the laser welding fixture to the preset installation position on the base plate. During processing, the workpiece to be processed is placed on the clamping block 5, which clamps and fixes the workpiece in place. Then, the workpiece is welded by the welding equipment.

[0037] This laser welding fixture uses an electromagnet as its magnetic base 1. By de-energizing the magnetic base 1, the laser welding fixture can be moved freely on the machine base plate, making it suitable for processing products with different weld seam positions and improving its versatility. When the laser welding fixture needs to be moved, simply de-energize the magnetic base 1, which will then move the fixture on the welding equipment's base plate. Once in the desired position, re-energizing the magnetic base 1 will magnetically attach it back to the base plate, re-installing and securing the laser welding fixture. The magnetic connection between the magnetic base 1 and the welding equipment's base plate allows for easy installation and removal of the laser welding fixture simply by energizing and de-energizing the magnetic base 1, without the need for any tools. This saves time and improves processing efficiency.

[0038] In this embodiment, there are two support frames 2 and two clamping seats 3, and they are arranged in a one-to-one correspondence; a gap 6 is reserved between the two clamping seats 3. During processing, the first workpiece is placed on the clamping block 5 in one of the clamping seats 3, and the workpiece is fixed by the clamping block 5; then the other workpiece is placed on the clamping block 5 in the other clamping seat 3, so that the two workpieces are joined at the gap 6, and then the workpieces are welded by welding equipment. In this way, during the welding process, the weld seam is exactly at the gap 6 between the two clamping seats 3, and some welding debris and residue will fall into the gap 6, preventing debris from falling onto the clamping block 5 and ensuring the cleanliness of the laser welding fixture.

[0039] In other embodiments, the number of support frame 2 and clamping seat 3 can also be any other number.

[0040] In this embodiment, each clamping base 3 is provided with multiple clamping blocks 5, and the multiple clamping blocks 5 are distributed in a straight line at equal intervals on the clamping base 3. By clamping and fixing the workpiece with multiple clamping blocks 5 simultaneously, the problem of workpiece displacement during welding processing can be avoided, thus improving the stability of processing. In other embodiments, the clamping blocks 5 can also adopt other distribution methods, such as multiple rows arranged in parallel, or multiple rows arranged in staggered positions, etc.

[0041] In this embodiment, the clamping block 5 is an electromagnet. After the workpiece is placed on the clamping block 5, the workpiece to be processed can be adsorbed or released by energizing or de-energizing the clamping block 5, thus improving the convenience of operation.

[0042] The support frame 2 is equipped with an adjustment component, which is connected to the clamping seat 3. This component is used to move the clamping seat 3 up and down on the support frame 2, thereby adjusting the height of the clamping seat 3 to meet the processing requirements of different workpieces. In actual processing, sometimes it is necessary for the two clamping seats 3 to be flush for welding, for example, when the two workpieces to be welded are the same height. Sometimes it is necessary for the two clamping seats 3 to be misaligned for welding, for example, when the two workpieces to be welded are not the same height. The adjustment component allows for arbitrary adjustment of the lifting and lowering movement of the corresponding clamping seat 3 on the support frame 2, achieving the purpose of adjusting the height of the clamping seat 3, making the two clamping seats 3 flush or misaligned, thus adapting to the processing needs of different scenarios and improving versatility.

[0043] Specifically, the adjustment assembly includes multiple adjusting screws 7. In this embodiment, four adjusting screws 7 are rectangularly distributed on each support frame 2. In other embodiments, the number of adjusting screws 7 can be any other number, as long as it can ensure that the clamping seat 3 can be pushed to rise stably. The adjusting screws 7 are threadedly connected to the support frame 2, with one end of the adjusting screw 7 extending out of the upper end face of the support frame 2, and the end of the adjusting screw 7 extending out of the upper end face of the support frame 2 abutting against the lower end face of the clamping seat 3.

[0044] Normally, the support frame 2 is fixedly connected to the clamping seat 3 by the fixing screw 4, and the adjusting screw 7 is threadedly connected to the support frame 2, with one end of the adjusting screw 7 abutting against the lower end face of the clamping seat 3. When it is necessary to adjust the height of the clamping seat 3, the fixing screw 4 can be loosened first, and then the adjusting screw 7 can be rotated to change the length of the adjusting screw 7 extending beyond the upper end face of the support frame 2. After adjustment, the fixing screw 4 of the support frame 2 and the clamping seat 3 can be tightened. In actual operation, if the length of the adjusting screw 7 extending beyond the upper end face of the support frame 2 increases, it will push the clamping seat 3 to rise; if the length of the adjusting screw 7 extending beyond the upper end face of the support frame 2 decreases, the clamping seat 3 will descend under its own weight until it abuts against the end face of the adjusting screw 7.

[0045] To facilitate the handling of the laser welding fixture, lifting rings 8 are installed at both ends of the support frame 2. When it is necessary to move the laser welding fixture, a hanging rope can be passed through the lifting rings 8, allowing the laser welding fixture to be lifted by an external hoist, reducing the difficulty of handling. In this embodiment, each support frame 2 has a lifting ring 8 at each end, and the laser welding fixture can be stably lifted by four lifting rings 8; in other embodiments, the number of lifting rings 8 can also be any other number.

[0046] To further reduce the difficulty of handling, each support frame 2 is provided with multiple weight-reducing hollow holes 21. By setting the weight-reducing hollow holes 21, the weight of the laser welding fixture can be reduced, so as to facilitate the lifting ring 8 or the handling of the laser welding fixture.

[0047] Example 2:

[0048] A laser welding device includes a base, on which a base plate and a laser welding head are mounted. The base plate is used to mount a laser welding fixture. During operation, the laser welding fixture is mounted on the base plate, and then the workpiece to be processed is mounted onto the laser welding fixture. The laser welding head then performs welding operations on the workpiece.

[0049] In this embodiment, the base plate is made of a magnetic metal material, such as an iron plate. In other embodiments, the base plate may also be equipped with a magnetic structure, which magnetically connects it to a magnetic base. For example, a permanent magnet or electromagnet may be installed on the base plate.

The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
