Description

Technical Field

[0001] The utility model relates to the technical field of welding workstations, in particular to a semi-automatic laser welding station. Background Art

[0002] Automobiles contain various bracket structures, such as VH brackets, lidar brackets, and tray brackets. These brackets are composed of multiple components. The components that make up the brackets are generally sheet metal parts, which need to be combined and welded into a whole using a fixture.

[0003] Semi-automatic bracket welding means that during the bracket welding process, workers manually assemble and fix each bracket to the corresponding fixture, and then place the fixture with the bracket assembly fixed on the welding position of the welding robot. Automatic welding is performed by the robot. The use of manual participation can greatly reduce the production cost of the bracket.

[0004] In the prior art, two workstations are generally set up on the support platform, one workstation is used by workers to assemble the bracket to the fixture, and the other workstation is where the welding robot is placed. After the workers complete the assembly, they move the fixture to the welding workstation for welding. During the welding period, the fixture is occupied, resulting in invalid working time during this period. When the welding is completed, the worker pulls back the fixture, then disassembles the welded bracket and needs to reinstall the new bracket assembly. During this period, the welding robot is in invalid working time, resulting in low overall work efficiency. Utility Model Content

[0008] The clamping platform includes a bottom bracket, a track fitting portion is provided at the bottom of the bottom bracket, the track fitting portion is slidably connected to the track, an upper bracket is rotatably connected above the bottom bracket, the upper bracket and the bottom bracket can be fixed by a locking member, and a clamp is installed above the upper bracket.

[0009] The fixture installation position deviates from the rotation axis of the upper bracket.

[0010] A pulling mechanism is provided between the working platform and each of the clamping platforms, and the pulling mechanism can enable the clamping platform to move between the installation station and the welding station.

[0011] The pulling mechanism includes an annular connecting rope and several pulleys rotatably connected to the working platform. The axes of the pulleys are vertically arranged. The connecting rope passes around multiple pulleys. The clamping platform is fixed to the connecting rope. The connecting rope is at least partially arranged along the track.

[0012] The pulling mechanism includes a screw rod and a nut connected by threads. The screw rod is rotatably connected to the working platform and is arranged along the track. The nut is fixed to the clamping platform.

[0013] The utility model proposes a semi-automatic laser welding station, which has the beneficial effect that: when the device is working, referring to the figure, when a workpiece on a clamping platform is being welded at a welding station, the welded workpiece can be removed from another clamping platform and a new workpiece can be loaded, so that the welding machine can be fully utilized.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 4 A semi-automatic laser welding station includes a working platform 1, a welding machine 4 is provided at one end of the working platform 1, two tracks 2 are provided on the working platform 1, the two tracks 2 are distributed in a V shape, and the welding machine 4 is located at one end of the V-shaped tip of the two tracks 2, and each track 2 is provided with a clamping platform 3.

[0021] When this device is working, refer to Figure 1 When a workpiece on a clamping platform 3 is being welded at a welding station, the welded workpiece can be removed from another clamping platform 3 and a new workpiece can be loaded, so that the welding machine 4 can be fully utilized.

[0022] When working, it is preferred to use two workers, each worker is responsible for one clamping platform 3, and the work efficiency is equivalent to twice the work efficiency of a traditional welding station. Of course, if the workpiece clamping is relatively simple, one worker can also operate two clamping platforms 3.

[0023] As an implementation method, refer to Figure 1 、 Figure 3 The clamping platform 3 includes a bottom bracket 5, a track matching part 9 is provided at the bottom of the bottom bracket 5, and the track matching part 9 is slidably connected to the track 2. An upper bracket 6 is rotatably connected above the bottom bracket 5, and the upper bracket 6 and the bottom bracket 5 can be fixed by a locking piece 7. A clamp 8 is installed above the upper bracket 6, and the entire clamping platform 3 can be moved on the track 2 through the cooperation of the track matching part 9 and the track 2. The device is provided with a rotatably connected upper bracket 6 and bottom bracket 5 in order to be able to change the orientation of the clamp 8. On the one hand, it is more convenient for workers to add workpieces, and on the other hand, it is convenient to adjust the workpieces on the two clamping platforms 3 to the same orientation. After the worker has clamped the workpiece, he needs to rotate the upper bracket 6 to adjust the workpiece to the orientation required for welding, and then fix it with the locking piece 7, and then move the clamping platform 3 to the welding station for welding. The locking part can be a locking nut, which is threadedly connected to the upper bracket 6. The end of the locking nut can abut against the bottom bracket 5. In order to facilitate the adjustment of the workpiece to the required orientation during welding, a hole can be set in the bottom bracket 5. When the end of the locking nut can be inserted into the hole, it is determined that the work position adjustment is completed.

[0024] As an implementation method, refer to Figure 1 、 Figure 2 The installation position of the clamp 8 deviates from the rotation axis of the upper bracket 6 and is eccentrically set so that when the locking parts 7 of the two clamping platforms 3 are moved to the welding station, the workpieces of the two clamping platforms 3 can be located in the middle position of the V-shape, so there is no need to set the welding machine to two working positions.

[0025] Of course, the welding machine 4 can also be set to two working modes, each mode corresponds to a clamping platform 3, and each clamping station is provided with a separate mode adjustment switch. The workpiece on which clamping platform 3 needs to be welded is adjusted to the corresponding mode.

[0026] Of course, a common track can also be set at one end of the two track tips of the V-shaped distribution, so that the orientations of the two clamping platforms 3 when they move to the common track are the same, and the welding machine only needs one working mode.

[0027] As an embodiment, a pulling mechanism is provided between the working platform 1 and each clamping platform 3 , and the pulling mechanism can enable the clamping platform 3 to move between the installation station and the welding station.

[0028] As an embodiment of the pulling mechanism, refer to Figure 4 The pulling mechanism includes a ring-shaped connecting rope 11 and several pulleys 10 rotatably connected to the working platform 1. The axis of the pulley 10 is vertically arranged. The connecting rope 11 passes around multiple pulleys 10. The clamping platform 3 is fixed to the connecting rope 11. The connecting rope 11 is at least partially arranged along the track 2. By pulling the connecting rope 11 forward or backward, the clamping platform 3 moves along the track to the welding station or the clamping station. This method has low cost.

[0029] As another embodiment of the pulling mechanism, the pulling mechanism includes a threaded screw and a nut. The screw is rotatably connected to the working platform 1 and is arranged along the track 2. The nut is fixed to the clamping platform 3, and the position of the clamping platform 3 is adjusted by rotating the screw.

[0030] The above is only a preferred specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and utility model concept of the present invention by any technical personnel familiar with the technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
