Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a circulating cooling tool for a laser welding machine. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. During the laser welding process, a forced cooling process is required to remove the heat generated by the welding, thereby improving the stability of the laser welding and the welding quality of the workpiece.

[0003] In the related art, a Chinese patent with authorization announcement number CN219212021U provides a laser welding machine with a cooling device, which includes a laser welding machine body, a coolant delivery pipe installed on the front side of the laser welding machine body, a welding platform set in front of the laser welding machine body, and liquid outlet pipes on both the left and right end surfaces of the welding platform. A collection hose is provided below the liquid outlet pipe, and the collection hose is connected to a collection box. A filter is installed in the collection hose. The coolant delivery pipe sprays coolant onto the workpiece, and the coolant dripping on the welding platform flows to the liquid outlet pipe. The coolant flows into the collection hose through the liquid outlet pipe. The filter in the collection hose filters impurities in the coolant, and the filtered coolant enters the collection box.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: due to the high content of impurities in the coolant, the filter located in the collection hose is prone to clogging, requiring staff to frequently maintain the filter, and when replacing and cleaning the filter, the staff needs to disassemble the collection hose first, resulting in cumbersome filter maintenance work during the coolant recovery process. Utility Model Content

[0005] In order to facilitate the recovery of coolant and simplify the maintenance of the filter, the present application provides a circulating cooling tooling for a laser welding machine.

[0006] The present application provides a circulating cooling tool for a laser welding machine that adopts the following technical solution:

[0007] A circulating cooling tooling for a laser welding machine comprises a welding table, a coolant tank being arranged below the welding table, an inlet pipe and an outlet pump being connected to the coolant tank, a coolant pipe being connected to the output end of the outlet pump, an end of the coolant pipe away from the outlet pipe being located above the welding table, a diversion groove being provided on the top of the welding table, a plurality of diversion holes being provided through the inner wall of the diversion groove, a water inlet being provided on the top of the coolant tank, the water inlet being located below the diversion holes, a winding roller being provided at one end of the welding table, an unwinding roller being provided at the other end of the welding table, a filter screen being wound around both the winding roller and the unwinding roller, and the filter screen being laid on the top of the welding table.

[0008] By adopting the above technical solution, the liquid outlet pump pumps the coolant in the coolant tank into the coolant pipe, so that the coolant pipe sprays the coolant onto the workpiece on the welding table, and the coolant dripping into the guide groove is filtered through the filter screen. The filtered coolant passes through the guide hole and flows into the coolant tank from the water inlet, thereby realizing the recycling of the coolant. When there are many impurities on the filter screen, the winding roller and the unwinding roller rotate synchronously to move the filter screen, so that the used filter screen is removed from the welding table and the unused filter screen is moved to the welding table, thereby reducing the situation where the staff frequently disassembles the pipeline. During the coolant recovery process, the maintenance work of the filter screen is simplified, thereby achieving the effect of facilitating the recovery of the coolant.

[0010] By adopting the above technical solution, the coolant in the diversion hole flows into the coolant tank from the water inlet through the diversion bucket and the diversion pipe. When there is too much coolant in the coolant tank, the shut-off valve blocks the diversion pipe, so that the coolant is temporarily stored in the diversion bucket, thereby reducing the overflow and waste of coolant due to excessive coolant in the coolant tank.

[0014] By adopting the above technical solution, the clamping cylinder adjusts the distance between the clamping seats, and the clamping seats move to adjust the distance between the drive plate and the abutment plate, so that the drive plate and the abutment plate clamp the workpiece. When the workpiece is fixed between the drive plate and the abutment plate, the clamping motor drives the drive plate to rotate, and the drive plate drives the workpiece to rotate, which facilitates laser welding of different positions of the workpiece.

[0015] Preferably, a reeling seat is fixedly provided at one end of the welding table, and the reeling seat is rotatably connected to the end wall of the reeling roller. A reeling seat is fixedly provided at the other end of the welding table, and a winding motor is fixedly provided on the reeling seat. The output end of the winding motor is connected to one end of the reeling roller, and the other end of the reeling roller is rotatably connected to the reeling seat.

[0016] By adopting the above technical solution, the winding motor drives the winding roller to rotate, and the rotation of the winding roller drives the filter to move, thereby achieving the effect of replacing the filter on the welding table.

[0017] Preferably, a group of unwinding shafts are rotatably arranged on the unwinding seat, an unwinding disk is fixedly arranged on the opposite surface of the unwinding shaft, and the unwinding disk is detachably connected to the end wall of the unwinding roller. A winding shaft is rotatably arranged on the winding seat, and a winding disk is fixedly arranged on the output shaft of the winding motor and the winding shaft, and the winding disk is detachably connected to the end wall of the winding roller.

[0018] By adopting the above technical solution, when the filter screen on the unwinding roller is used up, the unwinding disc and the unwinding roller are disassembled, and the winding disc and the winding roller are disassembled, so as to replace the filter screen.

[0019] Preferably, a waste box is arranged below the winding roller, an inlet and an outlet are symmetrically opened on the top of the waste box, the winding roller is located above the outlet, an abutment roller and a scraper plate are arranged in the waste box, a scraping channel is formed between the abutment roller and the scraper plate, and the scraping channel is located below the inlet.

[0020] By adopting the above technical solution, the filter screen on the welding table is moved into the scraping channel from the inlet, the scraper plate removes the impurities on the filter screen, and the scraped impurities fall into the waste box. The filter screen after the impurities are removed is moved out of the waste box from the outlet, and the filter screen moved out of the waste box is wound on the winding roller.

[0021] Preferably, a mounting opening is provided on the top of the waste box, the mounting opening is located between the inlet and the outlet, and a fan is fixedly installed in the mounting opening.

[0022] By adopting the above technical solution, the airflow generated by the fan performs secondary cleaning on the filter screen after the impurities are removed in the waste box, and blows the impurities attached to the filter screen into the waste box.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] By setting up a welding table, coolant tank, liquid inlet pipe, liquid outlet pump, coolant pipe, diversion groove, diversion hole, water inlet, winding roller, unwinding roller and filter screen, the situation of frequent pipe disassembly by workers is reduced. During the coolant recovery process, the maintenance work of the filter screen is simplified, so that the coolant recovery is facilitated.

[0033] The following is combined with Figures 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a circulating cooling tool for a laser welding machine. Figure 1 and Figure 2, comprising a welding table 1, with a coolant tank 2 installed below the welding table 1. A liquid inlet pipe 21 and a liquid outlet pump 22 are connected to the coolant tank 2, and a coolant pipe 23 is connected to the output end of the liquid outlet pump 22. A nozzle is installed on the end of the coolant pipe 23 away from the liquid outlet pipe, and the nozzle is located above the welding table 1. A diversion groove 12 is provided at the top of the welding table 1, and a plurality of diversion holes 11 are formed through the inner wall of the diversion groove 12. A water inlet 24 is provided at the top of the coolant tank 2, and the water inlet 24 is located below the diversion holes 11. A winding roller 4 is installed at one end of the welding table 1, and an unwinding roller 5 is installed at the other end of the welding table 1. A filter screen 9 is wound on both the winding roller 4 and the unwinding roller 5, and the filter screen 9 is laid on the top of the welding table 1. Support rollers 91 are installed at both ends of the welding table 1, and the filter screen 9 is wound on the top of the support roller 91. The support roller 91 is located above the winding roller 4 and the unwinding roller 5, and the top of the support roller 91 is flush with the top of the welding table 1. The liquid outlet pump 22 pumps the coolant in the coolant tank 2 into the coolant pipe 23, so that the coolant pipe 23 sprays the coolant onto the workpiece on the welding table 1 through the nozzle. The coolant dripping into the guide groove 12 is filtered by the filter 9, and the filtered coolant passes through the guide hole 11 and flows into the coolant tank 2 from the water inlet 24, realizing the recycling of the coolant. When there are many impurities on the filter 9, the winding roller 4 and the unwinding roller 5 rotate synchronously to move the filter 9, remove the used filter 9 from the welding table 1, and move the unused filter 9 to the welding table 1. During the coolant recovery process, the frequent disassembly of the pipeline by the staff is reduced, the maintenance work of the filter 9 is simplified, and the effect of facilitating the recovery of the coolant is achieved.

[0035] In order to reduce the waste of coolant overflow, refer to Figure 1 and Figure 2 A diversion hopper 3 is installed at the bottom of the welding table 1, with the diversion holes 11 located within the top of the diversion hopper 3. A diversion pipe 31 is installed at the bottom of the diversion hopper 3, and the bottom of the diversion pipe 31 is connected to the water inlet 24. A shutoff valve 32 is installed on the diversion pipe 31 to control the flow of the diversion pipe 31. The coolant in the diversion holes 11 flows through the diversion hopper 3 and the diversion pipe 31 from the water inlet 24 into the coolant tank 2. When the coolant in the coolant tank 2 is too much, the shutoff valve 32 blocks the diversion pipe 31, temporarily storing the coolant in the diversion hopper 3.

[0036] In order to fix the workpiece on the welding table 1, refer to Figure 1 and Figure 2A set of clamping brackets 6 are symmetrically installed on the welding table 1. Clamping cylinders 61 are installed on the opposite surfaces of the clamping brackets 6, and clamping seats 62 are installed on the output shafts of the clamping cylinders 61. An abutment plate 65 is rotatably set on one of the clamping seats 62, and a clamping motor 63 is installed on the other clamping seat 62. A drive plate 64 is installed on the output shaft of the clamping motor 63, and the drive plate 64 and the abutment plate 65 are arranged opposite to each other. The clamping cylinder 61 adjusts the distance between the clamping seats 62, and the clamping seat 62 moves to adjust the distance between the drive plate 64 and the abutment plate 65, so that the drive plate 64 and the abutment plate 65 clamp the workpiece. When the workpiece is fixed between the drive plate 64 and the abutment plate 65, the clamping motor 63 drives the drive plate 64 to rotate, and the drive plate 64 drives the workpiece to rotate, which facilitates laser welding of different positions of the workpiece.

[0037] In order to facilitate the replacement of the filter 9, refer to Figures 1 to 5 A reeling seat 51 is installed at one end of the welding table 1, and a reeling seat 41 is installed at the other end of the welding table 1. A set of reeling shafts 52 are rotatably provided on the reeling seat 51, and a reeling disc 53 is installed on the opposite surface of the reeling shaft 52. The reeling disc 53 is connected to the end wall of the reeling roller 5 by bolts. A winding motor 42 is installed on the reeling seat 41, and a reeling shaft 43 is rotatably provided on the reeling seat 41. A reeling disc 44 is installed on the output shaft of the winding motor 42 and on the reeling shaft 43. The reeling disc 44 is connected to the end wall of the reeling roller 4 by bolts. The reeling motor drives the reeling roller 4 to rotate, and the rotation of the reeling roller 4 drives the filter screen 9 to move, so that the filter screen 9 and the welding table 1 move relative to each other. When the filter screen 9 on the reeling roller 5 is used up, the reeling disc 53 is removed from the reeling roller 5, and the reeling disc 44 is removed from the reeling roller 4, so that the filter screen 9 can be replaced.

[0038] In order to clean the filter 9, refer to Figures 1 to 3 A waste bin 7 is installed below the winding roller 4, and a certain amount of liquid is injected into the waste bin 7. The top of the waste bin 7 is provided with an inlet 71, an outlet 72, and an installation opening 73. The installation opening 73 is located between the inlet 71 and outlet 72, and the inlet 71 and outlet 72 are symmetrically arranged. The winding roller 4 is located above the outlet 72, and a fan 74 is installed in the installation opening 73. An abutting roller 81 and a scraper 82 are installed in the waste bin 7. The scraper 82 is fixedly connected to the waste bin 7, and the abutting roller 81 is rotatably connected to the waste bin 7. A scraping channel 8 is formed between the abutting roller 81 and the scraper 82 and is located below the inlet 71. The filter 9 on the welding table 1 is moved into the scraping channel 8 through the inlet 71. The scraper 82 scrapes impurities on the filter 9. At the same time, the airflow generated by the fan 74 performs a secondary cleaning on the filter 9 in the waste bin 7, blowing impurities attached to the filter 9 into the waste bin 7. The filter screen 9 after hanging and removing impurities is moved out of the waste box 7 by the outlet 72, and the filter screen 9 moved out of the waste box 7 is wound on the winding roller 4. The impurities separated from the filter screen 9 fall into the liquid in the waste box 7, reducing the situation of impurity escape.

[0039] The implementation principle of a circulating cooling tool for a laser welding machine in an embodiment of the present application is as follows: the outlet pump 22 pumps the coolant in the coolant tank 2 into the coolant pipe 23, so that the coolant pipe 23 sprays the coolant onto the workpiece on the welding table 1 through the nozzle. The coolant dripping into the guide groove 12 is filtered by the filter 9, and the filtered coolant passes through the guide hole 11 and flows into the coolant tank 2 from the water inlet 24, thereby realizing the recycling of the coolant. When there are many impurities on the filter 9, the winding roller 4 and the unwinding roller 5 rotate synchronously to move the filter 9, remove the used filter 9 from the welding table 1, and move the unused filter 9 to the welding table 1. During the coolant recovery process, the situation where the staff frequently disassembles the pipeline is reduced, the maintenance work of the filter 9 is simplified, and the effect of facilitating the recovery of the coolant is achieved.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
