Description

Technical Field

[0001] This utility model relates to the field of laser welding fixtures and tooling technology, and in particular to a laser welding fixture and tooling with a correction function. Background Technology

[0002] Laser welding fixtures are auxiliary tools specifically designed for laser welding processes. Their main purpose is to ensure the accurate positioning and stable fixation of parts to be welded during the welding process, thereby improving welding quality and production efficiency. Laser welding fixtures are widely used in precision manufacturing fields such as automotive manufacturing, aerospace, and electronics.

[0003] Chinese invention patent application CN220838504U discloses a floating laser welding fixture, which includes a floating platform with a product fixture fixed in the middle and a clamping mechanism beside the product fixture. A spring-loaded floating mechanism is connected below the floating platform, and a pressing platform is provided above the floating platform. A pressure plate corresponding to the position of the product fixture is fixed in the middle of the pressing platform. A vertical lifting mechanism is connected below the pressing platform. This floating laser welding fixture can be embedded in the ground for convenient use in confined spaces; it can precisely weld planes using the floating mechanism, resulting in uniform welding; and a displacement sensor determines the welding status of the product, creating a closed-loop operation.

[0004] In existing technologies, workpieces requiring laser welding must first be fixed on the worktable using fixtures before welding. These fixtures typically use threaded connectors to lock the workpieces, but do not provide real-time positioning. This results in the welding blade needing to be positioned by centering during the welding process, causing the welding blade to take too long to reset and affecting production progress. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laser welding fixture with a correction function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser welding fixture with a calibration function includes a worktable and further includes:

[0008] The position correction component includes a clamping plate installed on one side of the workbench, and the clamping plate has screw holes and a second screw hole on its periphery respectively.

[0009] Guide rods are arranged in an array on one side of the clamp plate. A straightening cover is slidably mounted on the surface of the guide rods. A flange is provided on the side of the straightening cover, and a bolt is provided on the flange at the position corresponding to the screw hole.

[0010] A further technical solution involves installing a limit block on one side of the guide rod.

[0011] Further technical solutions also include:

[0012] The caliper correction assembly includes calipers that cover and are installed on both sides of the correction cover. The calipers have jaws on both sides, and screws are provided on the jaws at the positions corresponding to the second screw holes.

[0013] A further technical solution involves placing the workpiece to be welded on a fixture plate, with calipers clamping and holding it on the surface of the workpiece.

[0014] A further technical solution involves providing support legs at the bottom of the workbench, with stiffening plates connecting the support legs, foot pads covering the surface of the support legs, rounded corners around the support legs, and load-reducing grooves on the inner side of the support legs.

[0015] A further technical solution is to ensure that the dimensions of the correction cover are consistent with the external dimensions of the workpiece to be welded.

[0016] A further technical solution involves the caliper and jaws forming an "N"-shaped structure, with the belly of the caliper completely covering the surface of the workpiece.

[0017] Compared with the prior art, this utility model provides a laser welding fixture with a correction function, which has the following beneficial effects:

[0018] The position correction component addresses the lack of corrective positioning during workpiece clamping. The correction cover, used for clamping, is slidably mounted via a guide rod to achieve horizontal correction positioning. When the correction cover completely covers the workpiece surface, complete horizontal positioning of the workpiece is achieved.

[0019] To achieve effective vertical positioning and correction, we installed calipers on the unwelded sides of the straightening cover. These calipers, secured to the surface of the fixture plate by side jaws and threaded fasteners, achieve longitudinal positioning and correction. This structure prevents workpiece movement during welding. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figure 1 - Figure 4 A laser welding fixture with a correction function includes a worktable 1, the surface of which is a platform for performing the welding process, and further includes:

[0027] Position correction assembly 2 includes a clamping plate 9 mounted on one side of the workbench 1, which serves as the connection base for this device. The clamping plate 9 has screw holes 10 and second screw holes 15 respectively around its perimeter.

[0028] Guide rods 4 are arranged in an array on one side of the clamp plate 9. The guide rods 4 are the correction and positioning components of the correction cover 6. The correction cover 6 is slidably mounted on the surface of the guide rods 4. The side of the correction cover 6 is provided with a flange 7. The bolts 8 on the flange 7 are used to achieve the locking effect of the correction cover 6. The bolts 8 are provided on the flange 7 at the positions corresponding to the screw holes 10.

[0029] A laser welding fixture with a correction function has a limit block 5 installed on one side of the guide rod 4. The function of the limit block 5 is to prevent the correction cover 6 from falling off.

[0030] A laser welding fixture with a correction function further includes:

[0031] The caliper straightening assembly 3 includes calipers 12 that are mounted on both sides of the straightening cover 6. The calipers 12 are components that are mounted on the workpiece to achieve longitudinal position straightening. Jaws 13 are provided on both sides of the calipers 12, and screws 14 on the jaws 13 are used to lock the calipers 12. Screws 14 are provided on the jaws 13 at locations corresponding to the second screw holes 15.

[0032] A laser welding fixture with a correction function has a workpiece 11 to be welded placed on a fixture plate 9. The workpiece 11 is the source component to be welded after being clamped by this device. A clamp 12 is pressed and installed on the surface of the workpiece 11 to be welded.

[0033] A laser welding fixture with a correction function has a worktable 1 with legs 16 at the bottom, stiffeners 19 connecting the legs 16, foot pads 17 covering the surface of the legs 16, rounded corners 20 around the legs 16, and load-reducing grooves 18 on the inner side of the legs 16. All of the above are the supporting components of this utility model.

[0034] A laser welding fixture with a correction function has a correction cover 6 whose size is consistent with the outer dimensions of the workpiece 11 to be welded, so as to avoid the correction cover 6 being unable to fit onto the surface of the workpiece 11 to achieve the effect of correction and positioning.

[0035] A laser welding fixture with a correction function, wherein the caliper 12 and the jaws 13 together form an "N"-shaped structure, which has a stable positioning and holding effect. The belly of the caliper 12 completely covers the surface of the workpiece.

[0036] Working principle:

[0037] In the actual design process, this utility model addresses the following defects in the prior art: "In the prior art, before welding, the workpiece to be laser welded needs to be fixed on the worktable by a fixture. These fixtures generally use threaded connectors to lock the workpiece, but do not position the workpiece in real time. As a result, the welding knife needs to be positioned during the welding process, which makes the reset time of the welding knife too long and affects the production progress." Therefore, the position correction component 2 and the caliper correction component 3 are specifically proposed.

[0038] Position correction component 2:

[0039] This component improves upon traditional clamps, enhancing positioning and correction capabilities. The correction cover 6, originally designed for direct clamping, achieves vertical positioning and correction via guide rods 4. Once placed over the workpiece surface, it provides horizontal positioning and correction, preventing workpiece displacement during clamping. After positioning and clamping are complete, the correction cover 6 is secured inside screw holes 10 using bolts 8 on both flanges 7 for final positioning.

[0040] Caliper Correction Component 3:

[0041] Horizontal correction alone is insufficient because the workpiece may move during welding; therefore, vertical correction is also necessary. We selected the non-welding areas of the correction cover 6 and installed clamps 12 on them. The clamps 12 directly press against the surface of the workpiece 11 to be welded, achieving vertical positioning and fixation. The clamps 12 themselves achieve self-positioning and correction through screws 14 on the jaws 13 on both sides.

[0042] The design of this utility model realizes the position correction and positioning of the workpiece 11 to be welded in multiple directions, avoiding positional deviation of the workpiece during the welding process.
