Description

Technical Field

[0001] This application relates to the field of laser welding equipment, and in particular to a precision positioning device for laser welding products. Background Technology

[0002] Laser welding technology plays a vital role in modern industrial manufacturing and is widely used in fields such as automotive, electronics, and aerospace. Laser welding enables high-precision, high-strength connections, significantly improving product performance and production efficiency.

[0003] When the second workpiece is welded onto the first workpiece using laser welding, since both the first and second workpieces are grid-like structures, their structural strength is low, making them prone to shaking during the welding process, which reduces the welding quality. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a precise positioning device for laser welding products.

[0005] This application provides a precision positioning device for laser welding products, which adopts the following technical solution:

[0006] A laser welding product precision positioning device includes a base plate, a placement block disposed on the base plate, a placement groove formed on the placement block, a cover plate disposed above the placement groove, a lifting component and a positioning component for driving the cover plate to move up and down; the placement groove is used to place a first workpiece and a second workpiece, the cover plate is slidably connected to the placement block through the placement groove, the cover plate has a plurality of welding holes, and the placement block has a plurality of ventilation holes.

[0007] By adopting the above technical solution, the shaking phenomenon of the first and second workpieces during the welding process can be effectively reduced. Specifically, by setting up a placement groove for placing the first and second workpieces and using a cover plate to limit the workpieces, the stability of the workpieces during welding is improved, thereby enhancing the welding quality. In addition, the multiple welding holes on the cover plate facilitate laser welding operations, while the multiple vent holes on the placement block facilitate the introduction of inert protective gas, thereby preventing oxidation of the welded area and further improving the welding quality.

[0008] Preferably, the positioning component includes a plurality of positioning posts disposed in the placement groove and a plurality of first positioning holes formed on the first workpiece, wherein the positioning posts are connected to the placement block and the positioning posts are inserted into the first positioning holes.

[0009] By adopting the above technical solution, the positioning column is connected to the placement block and inserted into the first positioning hole of the first workpiece, thereby initially positioning the first workpiece, reducing the positional deviation of the first workpiece in the placement groove, providing an accurate initial position for the subsequent welding process, and thus improving the welding accuracy and quality.

[0010] Preferably, the cover plate has a plurality of second positioning holes, and the end of the positioning post extending out of the first positioning hole is inserted into the second positioning hole.

[0011] By adopting the above technical solution, the multiple second positioning holes on the cover plate cooperate with the ends of the positioning pins extending from the first positioning holes, which further enhances the positioning stability of the first and second workpieces in the placement groove. This design effectively reduces the shaking phenomenon of the first and second workpieces during the welding process, thereby improving the welding quality.

[0012] Preferably, a guide block is provided at the end of the positioning post away from the placement block, and the diameter of the end of the guide block near the positioning post is greater than the diameter of the end of the guide block away from the positioning post.

[0013] By adopting the above technical solution, a guide block is set at the end of the positioning post away from the placement block, and the end of the guide block near the positioning post has a larger diameter, which can guide the positioning post to be accurately inserted into the first positioning hole and the second positioning hole, avoiding displacement or jamming during the insertion process, thereby improving positioning accuracy and assembly efficiency.

[0014] Preferably, the positioning component further includes a positioning block disposed in the placement groove. The first workpiece has a strip-shaped hole, the positioning block is inserted into the strip-shaped hole, and one end of the positioning block away from the placement block extends out of the strip-shaped hole. The positioning block is used to limit the second workpiece.

[0015] By adopting the above technical solution, the positioning block is inserted into the strip hole on the first workpiece and limits the position of the second workpiece, thereby further improving the stability of the first and second workpieces during the welding process and effectively avoiding welding quality problems caused by workpiece shaking. In addition, the design of the positioning block makes the position of the second workpiece more precise, which helps to improve welding accuracy and overall welding effect.

[0016] Preferably, the lifting assembly includes multiple cylinders, one end of which is connected to the base and the other end of which is connected to the cover plate, and the multiple cylinders are symmetrically arranged at both ends of the placement block.

[0017] By adopting the above technical solution, the cylinders can drive the cover plate to rise and fall, thereby achieving the pressing and releasing of the first and second workpieces. Multiple cylinders are symmetrically arranged at both ends of the placement block, ensuring uniform force on the cover plate during lifting and lowering, avoiding inaccurate positioning of the first and second workpieces due to cover plate tilting, and thus improving the stability of the welding process.

[0018] Preferably, the bottom of the placement block is provided with a ventilation groove that communicates with the placement slot. The ventilation groove is located below the welding hole and communicates with the ventilation hole.

[0019] By adopting the above technical solution, the ventilation groove and ventilation hole are connected, which increases the contact area between the inert protective gas and the welding part, thereby improving the protective effect of the inert protective gas on the welding part and thus improving the welding quality.

[0020] In summary, this application has the following beneficial technical effects:

[0021] By combining the placement slot and positioning components, the first and second workpieces can be accurately positioned. The cover plate limits the movement of the first and second workpieces, effectively reducing the shaking of the first and second workpieces during welding, thereby significantly improving the welding quality.

[0022] The sliding connection design between the cover plate and the placement groove, combined with the welding holes on the cover plate, can provide a precise operating position for laser welding while fixing the workpiece, further enhancing the stability of the welding process.

The placement groove 21 is used to place a first workpiece 6 and a second workpiece 7. The cover plate 3 is slidably connected to the placement block 2 via the placement groove 21, and is used to press the first workpiece 6 and the second workpiece 7 together. The cover plate 3 has multiple welding holes 31, and the placement block 2 has multiple vent holes 22. Inert protective gas is supplied to the placement groove 21 through the vent holes 22, allowing the inert protective gas to protect the welding area, reducing oxidation and improving welding quality. There are two second workpieces 7, which are respectively positioned at opposite ends of the first workpiece 6.

[0032] Reference Figure 3 , Figure 4 and Figure 5 The positioning component 5 includes two positioning posts 51 disposed in the placement groove 21 and two first positioning holes 61 opened on the first workpiece 6. The positioning posts 51 are fixedly connected to the placement block 2 and are inserted into the first positioning holes 61. The two positioning posts 51 are symmetrically arranged at both ends of the placement groove 21.

[0033] The cover plate 3 has two second positioning holes 32, and the end of the positioning post 51 extending out of the first positioning hole 61 is inserted into the second positioning hole 32.

[0034] A guide block 52 is fixedly provided at the end of the positioning post 51 away from the placement block 2. The diameter of the end of the guide block 52 near the positioning post 51 is greater than the diameter of the end of the guide block 52 away from the positioning post 51.

[0035] The positioning assembly 5 also includes positioning blocks 53 disposed in the placement groove 21. A strip-shaped hole 62 is formed on the first workpiece 6, and the positioning block 53 is inserted into the strip-shaped hole 62. One end of the positioning block 53, away from the placement block 2, extends out of the strip-shaped hole 62. The positioning block 53 is used to limit the positioning of the second workpiece 7. There are four positioning blocks 53, symmetrically arranged at both ends of the placement groove 21. Two positioning blocks 53 form a group, and one group of positioning blocks 53 limits the positioning of one second workpiece 7.

[0036] The lifting assembly 4 includes two cylinders 41. One end of the cylinder 41 is fixedly connected to the base, and the other end is fixedly connected to the cover plate 3. The two cylinders 41 are symmetrically arranged at both ends of the placement block 2.
