Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a welding robot welding unit. Background Technology

[0002] In existing automotive parts welding production, traditional welding units typically employ a single welding station or a simple sequential welding method. After completing the welding of a group of workpieces, the welding robot needs to stop working and wait for workers to remove the welded workpieces from the welding platform and place new workpieces to be welded before it can continue welding the next group of workpieces. This stagnation of the welding robot due to workpiece loading and unloading severely impacts production efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a welding robot welding unit that solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a welding robot welding unit, comprising a welding robot, and further comprising:

[0005] Several welding platforms are arranged circumferentially next to the welding robot. Each welding platform is equipped with a workpiece fixing cluster. Each workpiece fixing cluster fixes several workpieces through a snap-fit ​​structure. The welding robot can weld the workpieces fixed by the workpiece fixing cluster on each welding platform in sequence.

[0006] Furthermore, the workpiece fixing cluster includes a base plate installed on the upper part of the welding platform. A beam frame and a constraint component are respectively installed on the upper part of the base plate. Several baffles are installed on the front of the beam frame, and several quick clamps are installed on the back of the beam frame. Limiting plates are inserted between the baffles.

[0007] Furthermore, the limiting plate abuts against the front of the workpiece, and the clamping end of the quick clamp abuts against the back of the workpiece.

[0008] Furthermore, each baffle has a stepped groove pre-cut on its side, and the edge of the limiting plate is inserted into the stepped groove.

[0009] Furthermore, the top of the constraint member is symmetrically connected with limiting protrusions, and limiting grooves are set between the limiting protrusions.

[0010] Furthermore, the front end of the workpiece is engaged inside the limiting groove.

[0011] This invention provides a welding robot welding unit. Compared with the prior art, it has the following advantages:

[0012] Beneficial effects:

[0013] This welding robot welding unit, through the coordinated design of multiple welding platforms and workpiece fixing clusters, enables the parallel operation of welding robot welding and workpiece loading and unloading. While the welding robot is welding one set of workpieces, the operator can simultaneously unload another set of completed workpieces and place new workpieces to be welded. This avoids situations where the welding robot stops waiting due to workpiece loading and unloading, greatly improves the utilization rate of welding equipment, significantly enhances the overall welding efficiency of automotive parts, effectively shortens the production cycle, and reduces enterprise production costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7This utility model provides a technical solution: a welding robot welding unit, mainly composed of a welding robot 1, several welding platforms 2, and workpiece fixing clusters 3 installed on the welding platforms 2. Several welding platforms 2 are arranged circumferentially beside the welding robot 1. The welding robot 1 can sequentially weld the workpieces fixed by the workpiece fixing clusters 3 on each welding platform 2, achieving efficient and continuous welding operations. When the welding unit is working, the welding robot 1 welds the workpieces fixed by the workpiece fixing clusters 3 on one set of welding platforms 2. While welding this set of workpieces, the operator can remove another set of welded workpieces from the workpiece fixing clusters 3 and place new workpieces to be welded, repeating this cycle. In this way, the welding robot 1 will not stop due to the loading and unloading of workpieces, significantly improving the welding efficiency.

[0024] Welding robot 1 adopts existing mature welding robot products, possessing multi-axis motion capabilities and the ability to precisely control welding position and welding parameters. Installed at the center of the welding unit, it can move sequentially to each welding platform 2 according to a preset program to perform welding operations.

[0025] The workpiece fixing cluster 3 consists of a base plate 31, a beam frame 32, constraint members 33, a baffle 34, a limiting plate 35, and a quick clamp 36, wherein:

[0026] The base plate 31 is a rectangular steel plate, which is fixedly installed on the upper part of the welding platform 2 by bolts. The dimensions of the base plate 31 are designed according to the size of the welding platform 2 and the workpiece fixing requirements to ensure sufficient installation space;

[0027] The beam frame 32 is fixedly installed on the upper part of the base plate 31 by bolts. Several baffles 34 are installed on its front side (i.e. the side facing the welding robot 1), and several quick clamps 36 are installed on its back side. The number of baffles 34 and quick clamps 36 is reasonably set according to the shape and size of the workpiece.

[0028] The baffle 34 is bolted to the front of the beam frame 32. Each baffle 34 has a stepped groove 341 pre-cut on its side. The size of the stepped groove 341 is designed according to the edge size of the limiting plate 35 to ensure that the edge of the limiting plate 35 can be accurately inserted into the inside of the stepped groove 341.

[0029] The quick clamp 36 uses an existing quick clamping device and is bolted to the back of the beam frame 32. The clamping end of the quick clamp 36 is adjustable and can be adjusted according to the size of the workpiece to ensure a tight fit with the back of the workpiece.

[0030] The edge of the limiting plate 35 is inserted into the stepped groove 341 of the baffle 34. The limiting plate 35 abuts against the front of the workpiece, thus limiting the position of the front of the workpiece. The dimensions of the limiting plate 35 are customized according to the shape and size of the workpiece to ensure accurate limiting of the workpiece.

[0031] The constraint member 33 is bolted to the upper part of the base plate 31. The top of the constraint member 33 is symmetrically connected to the limiting protrusions 331, and the limiting protrusions 331 are configured with limiting grooves 332. The front end of the workpiece is engaged inside the limiting grooves 332, further restricting the position of the workpiece and ensuring the stability of the workpiece during the welding process.

[0032] Work process:

[0033] Place the workpiece 4 to be welded on the workpiece fixing cluster 3, so that the front end of the workpiece 4 is engaged inside the limiting groove 332 of the constraint member 33.

[0034] The edge of the limiting plate 35 is inserted into the stepped groove 341 of the baffle 34, so that the limiting plate 35 abuts against the front of the first workpiece 4.

[0035] Operate the quick clamp 36 so that the clamping end of the quick clamp 36 abuts against the back of the first workpiece 4. With the help of the limiting plate 35, the first workpiece 4 is firmly fixed on the workpiece fixing cluster 3. Finally, the second workpiece 5 is placed on the surface of the first workpiece 4 to be welded.

[0036] Start welding robot 1. Welding robot 1 moves sequentially above each welding platform 2 according to the preset program;

[0037] The welding head of welding robot 1 is aligned with the workpiece fixed on workpiece fixing cluster 3 to perform welding operations;

[0038] After completing the welding of a workpiece on welding platform 2, welding robot 1 welds the workpiece on the next welding platform 2. At the same time, the worker removes the previously welded workpiece and replaces it with a new workpiece to be welded, repeating the above welding process to efficiently complete the welding work.
