Description

Technical Field

[0001] The utility model relates to the technical field of jacking mechanisms, and particularly relates to a jacking mechanism for a laser welding machine. Background Technique

[0002] In this era of increasingly fierce competition between enterprises, the level of cost and production efficiency will directly affect the development of enterprises. Currently, the jacking mechanism of a laser welding machine usually uses a servo module or a cylinder as the main jacking component. However, the method of jacking with a servo module is costly, and the method of jacking with a cylinder has poor flexibility.

[0003] A jacking mechanism for a laser welding machine disclosed in a prior patent (Publication No.: CN220498069U) fixes multiple groups of workpieces through multiple groups of clamping mechanisms respectively, then adjusts the positions of multiple groups of welding tables through a rotating mechanism, and then lifts the front welding table to a suitable height through a lifting device, so that the laser welding machine performs welding processing on the workpieces. Then, the lifting device resets, the rotating mechanism rotates again, moves another group of welding tables to the front side, and lifts another group of welding tables to a suitable height through the lifting device. At the same time, the operator removes the workpieces that have been welded and processed on one group of welding tables and replaces them with new workpieces, thereby improving the practicability of the equipment.

[0004] However, the above technical solution still has certain defects. Since laser welding uses high-energy laser pulses to locally heat materials in a small area, when the laser welding machine performs laser welding, the energy generated by the laser will melt the material into a high-temperature liquid state. On the one hand, when the operator makes a mistake in the laser welding operation, the high-temperature liquid material will splash onto the human body, causing burns to human body parts. On the other hand, the high-temperature liquid material splashes everywhere, making it inconvenient for subsequent workers to clean up. Therefore, a jacking mechanism for a laser welding machine is proposed. Content of the Utility Model

[0028] Next, the embodiments of the present utility model will be described according to its overall structure.

[0029] A jacking mechanism of a laser welding machine, as Figure 1-6As shown, the workbench body 100 includes a rotating column 110 connected to the workbench body 100 through a bearing, a sleeve 150 is fixedly sleeved on the outer wall of the rotating column 110, and three groups of one-way screws 160 are longitudinally arranged in the sleeve 150 and are equidistantly distributed in a circle. The top of each group of one-way screws 160 extends through and extends above the sleeve 150 and is fixedly installed with a second motor 170. The outer wall of each group of one-way screws 160 is threadedly connected to a first slider 180, and one side of each group of first sliders 180 is fixedly connected to The first connecting rod 182, the other end of each group of first connecting rods 182 is fixedly installed with a welding platform 190, each group of welding platforms 190 is installed with a clamping assembly 200, the upper surface of each group of welding platforms 190 is provided with a clearance groove for the clamping assembly 200 to move, and each group of clearance grooves is installed with an anti-drop assembly 300; the clamping assembly 200 includes a bidirectional screw rod 210 transversely arranged in the welding platform 190, one end of the bidirectional screw rod 210 is installed with a third motor 220, and the outer surface of the bidirectional screw rod 210 is provided with a third motor 220. The two ends of the wall are threadedly connected with second sliders 230, the tops of the two groups of second sliders 230 are fixedly connected with second connecting rods 240, and the two groups of second connecting rods 240 are all penetrated through the give way groove and extend to the top of the welding platform 190. The tops of the two groups of second connecting rods 240 are fixedly installed with clamping plates 250. A rotating shaft 260 is horizontally provided on one side of the bidirectional screw rod 210 in the welding platform 190. The outer ends of the rotating shaft 260 are fixedly sleeved with third gears 280, and one side of each group of third gears 280 is A rack 290 is meshed, and the two sets of racks 290 are slidably connected to the side walls of the welding table 190. The two sets of racks 290 are fixedly connected to a fixed block 2910 on the side away from the third gear 280, and the other sides of the two sets of fixed blocks 2910 are fixedly connected to the same protective frame 2920.

[0032] By setting the rollers 181, the up and down movement of the welding table 190 is made more stable. By opening the movable grooves 151, a moving space is provided for the up and down movement of the first connecting rod 182. A notch larger than the size of the first connecting rod 182 is provided at the center of one side of the protective frame 2920, providing space for the up and down movement of the protective frame 2920.

A shielding cloth 320 is wound around the outer wall of the rotating shaft 310, and the other end of the shielding cloth 320 is fixedly connected to the side wall of the second connecting rod 240. A torsion spring 330 is sleeved on the outer walls at both ends of each rotating shaft 310. One end of the torsion spring 330 is fixedly connected to the side wall of the inner cavity at the top of the welding table 190, and the other end is fixedly connected to the outer wall of the rotating shaft 310.

[0034] Along with the movement of the second connecting rod 240 and the clamping plate 250, the shielding cloth 320 fixed to one side of the second connecting rod 240 is driven to stretch, and the shielding cloth 320 on the other side is wound onto the outer wall of the rotating shaft 310 to completely cover the relief groove, preventing liquid materials from splashing into the relief groove and causing inconvenience in subsequent cleaning. It should be noted that all the torsion springs 330 are initially tensioned.
