In the process of automatic welding of automotive parts, such a complex set of welding fixtures constantly moves with the slide every day, which will also have an adverse effect on the stability of the equipment. For this reason, a slide mechanism is specially provided for a robot welding workstation. Utility Model Content

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-Figure 7 , the utility model provides a technical solution:
[0025] A slide mechanism for a robot welding workstation comprises a workbench 1, four support blocks 11 are symmetrically fixedly installed on the upper surface of the workbench 1, a slide rail 12 is fixedly installed between two corresponding support blocks 11 on the left and right, two sliders 13 are slidably installed on the upper surface of the slide rail 12, a welding robot mounting seat 14 with mounting holes is fixedly installed between the upper surfaces of the four sliders 13, a rack plate 2 is fixedly installed on the front surface of the workbench 1, a travel motor 3 is fixedly installed on the lower surface of the front end of the welding robot mounting seat 14, an output end of the travel motor 3 is sleeved with a gear 31, the gear 31 is meshed with the rack plate 2, a shielding shell 4 is fixedly installed on the rear end of the welding robot mounting seat 14, the travel motor 3 is located in the shielding shell 4, cleaning structures are arranged on the left and right sides of the shielding shell 4, and a directional lubrication device 5 is installed on the front surface of the shielding shell 4;
[0026] Combination Figure 1 and Figure 2 As shown, during installation, the robot welding equipment can be installed on the upper surface of the welding robot mounting seat 14 by bolts. After the travel motor 3 is connected to the external power supply and the external control system, the travel motor 3 can be controlled to rotate in the forward and reverse directions, so that the welding robot mounting seat 14 can be driven to move left and right through the connection effect between the gear 31 and the rack plate 2, so that the welding robot can realize the picking and placing of automobile parts in a larger range, and it is also more convenient to adjust the controller angle for picking up and placing automobile parts;
[0027] When the welding robot mounting base 14 moves, the shielding shell 4 and the directional lubrication device 5 can move with it. The shielding shell 4 can effectively shield the front and left and right sides of the walking motor 3, thereby preventing foreign matter from entering the connection between the gear and the rack plate and affecting the walking stability of the walking motor 3, while the directional lubrication device 5 can lubricate the gear 31. When the gear 31 moves on the front surface of the rack plate 2, the lubricating oil will be smeared on the front surface of the rack plate 2 to lubricate it, thereby facilitating the maintenance of the gear 31 and the rack plate 2.
[0028] It is worth noting that the load-bearing capacity of the slide block 13 is reduced. Figure 1As shown, a support plate 111 is fixedly installed between the upper surfaces of the four support blocks 11. Figure 7 As shown, four load-bearing wheels 141 are fixedly installed on the lower surface of the welding robot mounting seat 14. When the slider 13 is slidably installed on the slide rail 12, the lower surface of the load-bearing wheel 141 fits with the upper surface of the support plate 111. The weighing wheel 141 can be used to share the weight of the slider 13, thereby extending the service life of the slider 13.
[0029] Specifically, the cleaning structure is a cleaning plate 6 with bristles. The bristles of the cleaning plate 6 fit into the tooth gaps of the rack plate 2. The cleaning plate 6 can move with the shielding shell 4. The bristles of the cleaning plate 6 can be used to clean the path that the gear 31 is to travel in advance, thereby avoiding dust particles in the tooth gaps of the rack plate 2 that affect the meshing effect with the gear 31.
[0030] Specifically, the directional lubrication device 5 includes an oil injection pump 51 and an oil storage bottle 52. The oil injection pump 51 is fixedly installed on the front surface of the shielding shell 4, and a nozzle 511 is provided at the oil injection end of the oil injection pump 51. The nozzle 511 is embedded and installed in the shielding shell 4. The oil injection position of the nozzle 511 corresponds to the position of the gear 31. The oil storage bottle 52 is screwed on the lower surface of the shielding shell 4, and an oil extraction pipe 512 is connected between the oil storage bottle 52 and the oil inlet end of the oil injection pump 51. The oil injection pump 51 can supply the lubricating oil in the oil storage bottle 52 into the nozzle 511 through the oil extraction pipe 512 for spraying, thereby lubricating and maintaining the gear 31.
[0031] In order to facilitate the recovery of the lubricating oil dripping from the outer surface of the gear 31, when installing the shielding shell 4, it is necessary to fit the inner surface of the bottom end of the shielding shell 4 with the lower surface of the rack plate 2, and a collecting port 41 is opened through the lower surface of the shielding shell 4. After the collecting port 41 is set above the bottle mouth of the oil storage bottle 52, the oil dripping from the outer surface of the gear 31 can flow back into the oil removal bottle 52 through the collecting port 41 for recovery and reuse.
[0032] Finally, in order to facilitate the filtration of the recovered lubricating oil, Figure 4 As shown, a slot 42 is opened on the front surface of the shielding shell 4, the slot 42 passes through the collecting port 41, and a filter plate 43 is inserted and installed in the slot 42, and a filter screen 431 is fixedly installed in the filter plate 43. After the filter screen 431 is located in the collecting port 41, the filter screen 431 can be used to filter the lubricating oil in the recovery process, thereby reducing impurities in the lubricating oil recovered into the oil storage bottle 52.
