Description

Technical Field

[0001] The invention belongs to the technical field of heat transfer plate production equipment, in particular to a heat transfer plate laser welding follower gas protection tooling. Background Art

[0002] Laser welding uses a high-energy-density laser beam to heat the welding point. Since the beam needs to be emitted through the lens of the welding machine, the lens needs to be guaranteed not to be contaminated. Otherwise, beam refraction problems may occur during the laser emission process, causing the laser head to be burned. Therefore, in the laser welding process, shielding gas plays a vital role.

[0003] Since the end of laser welding is usually a cylinder, evenly setting up protective gas nozzles at the end can provide effective protection. However, setting too many nozzles will lead to a decrease in the pressure-bearing capacity of a single nozzle. When performing high-speed jet operation, the nozzle may be damaged due to the strong air pressure, so improvements are needed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: a heat transfer plate laser welding follower gas shielding tooling, comprising a containing frame, wherein a welding device is arranged inside the containing frame;

[0005] The welding device comprises an outer cover tube, and compression sleeves are symmetrically arranged on the front and rear sides of the outer surface of the outer cover tube, and a plug-in guide plate is fixedly connected to the side of the inner wall of the compression sleeve away from the outer cover tube, and the plug-in guide plate can control the elongation and contraction of the compression sleeves on both sides by means of pressurization and decompression, thereby achieving the effect of longitudinally pulling the outer cover tube, and a sliding end plate is fixedly connected to the end of the plug-in guide plate away from the compression sleeve;

[0006] The inner wall of the outer cover tube is fixedly connected with a jet device at the axis center, the middle of the inner wall of the jet device is provided with a protective device, and the top of the protective device is provided with a welding end;

[0007] The welding end comprises an energy supply box, the top of the inner cavity of the energy supply box is evenly provided with external wires, an outer push rod is slidably connected to the axis of the inner cavity of the energy supply box, the bottom end of the outer push rod is fixedly connected to a laser emitter, a bottom protective shell is fixedly connected to the axis of the lower surface of the energy supply box, an extended outer disk is fixedly connected to the middle of the outer surface of the bottom protective shell, and a rolling mechanism is evenly provided on the lower surface of the extended outer disk. The welding end structure is as follows Figure 4 As shown, it is an independent structure and can be completely removed from the inside of the welding device.

[0008] Furthermore, the protection device includes a sleeve shell, the inner cavity of the sleeve shell is evenly provided with auxiliary rollers, the top of the sleeve shell is evenly provided with occlusal grooves, the top of the outer surface of the sleeve shell is sleeved with a guide ring, and the outer surface of the sleeve shell is evenly provided with a drainage device. The rolling mechanism includes a power supply bracket, the bottom end of the power supply bracket is fixedly connected with a bidirectional motor, both ends of the output shaft of the bidirectional motor are fixedly connected with a reinforcing rod, and the end of the reinforcing rod away from the bidirectional motor is fixedly connected with an occlusal rotating gear, the top of the power supply bracket is fixedly connected to the inner cavity of the extended outer disk, the outer surface of the occlusal rotating gear is meshed with the inner wall of the occlusal groove, the welding end is connected to the occlusal groove at the top of the sleeve shell through the six groups of rolling mechanisms below, and then the occlusal rotating gear is twisted by the bidirectional motor to control the sleeve shell to rotate actively, and when the auxiliary roller rotates at high speed with the sleeve shell, it will roll and rub with the outer surface of the bottom protective shell, thereby avoiding the problem of wear on the bottom protective shell.

[0009] Furthermore, the outer surface of the auxiliary roller is rollingly connected to the inner wall of the sleeve shell, the outer surface of the bottom protective shell is rollingly connected to the inner wall of the sleeve shell through the auxiliary roller, a spring washer is sleeved in the middle of the outer surface of the laser emitter, and the bottom end of the spring washer is fixedly connected to the inner wall of the bottom protective shell.

[0010] Furthermore, the jet equipment includes an air dividing ring shell, and a sliding inner ring is rotatably connected to the side of the inner cavity of the air dividing ring shell close to the drainage device through an annular groove. The sliding inner ring can rotate relative to the air dividing ring shell and seals the sliding inner ring. A docking end is fixedly connected to the side of the inner cavity of the air dividing ring shell away from the drainage device through a through opening, and a filter block is fixedly connected to the end of the docking end away from the air dividing ring shell, a pressure pump is fixedly connected to the top of the filter block, and a drainage pipe is fixedly connected to the air inlet of the pressure pump.

[0011] Furthermore, the drainage device includes a bending connecting tube, the bottom end of which is fixedly connected to a guide end, the bottom of the outer surface of the bending connecting tube is sleeved with a limiting tube shell, the top of the limiting tube shell is fixedly connected to a pressure-sensitive plug plate, the top of the inner wall of the pressure-sensitive plug plate is slidably connected to a plug-in slide plate, and the sliding inner ring is docked with the bending connecting tube. By setting the sliding inner ring, when the bending connecting tube rotates, it will not cause torque interference to the air dividing ring shell.

[0012] Furthermore, the top end of the bending connecting tube is fixedly connected to the inner cavity of the sliding inner ring through an embedded chuck, and the top end of the bending connecting tube extends to the interior of the air dividing ring shell, the side of the outer surface of the limiting tube shell away from the bending connecting tube is fixedly connected to the outer surface of the sleeve tube shell, and the side surface of the air dividing ring shell is fixedly connected to the inner wall of the outer cover tube.

[0013] Furthermore, the containing frame includes a control bottom frame, the inner cavity of the control bottom frame is evenly provided with vertical push rods, the top of the vertical push rods is provided with a welding plate, and the front and rear sides of the upper surface of the control bottom frame are symmetrically provided with longitudinal controllers. The longitudinal controller is a pressure control device that can pressurize the connected containers by pumping air from the outside, and can also perform pressure extraction. A ventilation pipe is fixedly connected to the output port of the longitudinal controller, and the left and right sides of the outer surface of the longitudinal controller are fixedly connected to side pulling devices through traction belts.

[0014] Furthermore, the bottom of the side-pulling device is fixedly connected to the upper surface of the control bottom frame, the lower surface of the longitudinal controller is fixedly connected to the upper surface of the sliding end plate, the inner wall of the sliding end plate is slidably connected to one side of the upper surface of the control bottom frame, and the end of the ventilation pipe away from the longitudinal controller is fixedly connected to the inner cavity of the plug-in guide plate.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The device can spray the welding end of the laser emitter through the drainage device on the outer surface of the sleeve shell, and use the protective gas to prevent the welding end from being contaminated. Since too many nozzles will lead to a decrease in the pressure-bearing capacity of a single nozzle and a high cost, the device uses a small amount of drainage equipment to enable the sleeve shell to rotate, so that the protective gas sprayed by the drainage equipment can completely cover the bottom end of the laser emitter, thereby solving the above problem.

[0017] 2. The welding end of the device controls the rotation of the protective device through the rolling mechanism below, and the welding end is relatively independently arranged and can be pulled out from the inside of the sleeve shell, which is very convenient for the subsequent maintenance of the laser transmitter. After the welding end is inserted into the protective device, it can only rely on its own gravity to make the occlusal rotating teeth and the occlusal cutting groove docking, so there will be no problem of loose docking between the occlusal rotating teeth and the occlusal cutting groove, resulting in slipping.

[0018] 3. The laser emitter of the device is usually retracted inside the bottom protective shell to avoid being contaminated by external impurities. When the outer push rod is pressed down to push out the laser emitter, the compressed pressure of the spring washer will be transmitted to the bottom protective shell, thereby further increasing the tightness of the connection between the rolling mechanism and the occlusal groove. When the drainage device rotates, the external air distribution ring shell always remains stationary, so it can avoid the problem of the operator's hand accidentally touching the high-speed rotating drainage device and causing injury.

[0019] 4. When the drainage equipment is working, if the bending connecting tube used to transport gas moves under the action of air pressure, the bending connecting tube must slide along the fixed inner wall of the limiting tube shell. At this time, the bending connecting tube will drive the plug-in slide to move relative to the fixed pressure-sensitive plug-in plate. Since the plug-in slide can trigger the corresponding pressure-sensitive plug-in plate as long as it slides, maintenance work can be carried out in time when the bending connecting tube has not become seriously loose, so as to avoid production accidents.

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0030] Example 1, please refer to Figure 1-Figure 5 , the present invention provides a technical solution: a heat transfer plate laser welding follower gas shielding tooling, comprising a containing frame 1, wherein a welding device 2 is arranged inside the containing frame 1;

[0031] The welding device 2 includes an outer cover tube 21, and compression sleeves 22 are symmetrically arranged on the front and rear sides of the outer surface of the outer cover tube 21. A plug-in guide plate 23 is fixedly connected to the side of the inner wall of the compression sleeve 22 away from the outer cover tube 21. The plug-in guide plate 23 can control the elongation and contraction of the compression sleeves 22 on both sides by means of pressurization and decompression, thereby achieving the effect of longitudinally pulling the outer cover tube 21. A sliding end plate 24 is fixedly connected to one end of the plug-in guide plate 23 away from the compression sleeve 22.

[0032] The jet device 5 is fixedly connected to the axis center of the inner wall of the outer cover tube 21, the middle of the inner wall of the jet device 5 is provided with a protective device 4, and the top of the protective device 4 is provided with a welding end 3;

[0033] The welding end 3 includes an energy supply box 31, the top of the inner cavity of the energy supply box 31 is evenly provided with an external wire 32, an outer push rod 33 is slidably connected to the axis of the inner cavity of the energy supply box 31, and a laser emitter 35 is fixedly connected to the bottom end of the outer push rod 33. A bottom protective shell 34 is fixedly connected to the axis of the lower surface of the energy supply box 31, and an extended outer disk 37 is fixedly connected to the middle of the outer surface of the bottom protective shell 34. The lower surface of the extended outer disk 37 is evenly provided with a rolling mechanism 6. The structure of the welding end 3 is as follows Figure 4 As shown, it is an independent structure and can be completely removed from the inside of the welding device 2.

[0034] The protection device 4 includes a sleeve shell 41, the inner cavity of the sleeve shell 41 is evenly provided with auxiliary rollers 44, the top of the sleeve shell 41 is evenly opened with bite grooves 43, the top of the outer surface of the sleeve shell 41 is sleeved with a guide ring 42, and the outer surface of the sleeve shell 41 is evenly provided with drainage equipment 7. The rolling mechanism 6 includes a power supply card frame 61, the bottom end of which is fixedly connected to a bidirectional motor 62, both ends of the output shaft of the bidirectional motor 62 are fixedly connected to a reinforcing rod 63, and the end of the reinforcing rod 63 away from the bidirectional motor 62 is fixedly connected to an engaging gear 64, the top of the power supply card frame 61 is fixedly connected to the inner cavity of the extended outer disk 37, the outer surface of the engaging gear 64 is meshed with the inner wall of the engaging groove 43, the welding end 3 is docked with the engaging groove 43 at the top of the sleeve shell 41 through the six groups of rolling mechanisms 6 below, and then the engaging gear 64 is twisted by the bidirectional motor 62 to control the sleeve shell 41 to actively rotate, and when the auxiliary roller shaft 44 rotates at a high speed with the sleeve shell 41, it will roll and rub with the outer surface of the bottom protective shell 34, thereby avoiding wear problems on the bottom protective shell 34.

[0035] The outer surface of the auxiliary roller 44 is rollingly connected to the inner wall of the sleeve shell 41, and the outer surface of the bottom protective shell 34 is rollingly connected to the inner wall of the sleeve shell 41 through the auxiliary roller 44. A spring washer 36 is sleeved in the middle of the outer surface of the laser emitter 35, and the bottom end of the spring washer 36 is fixedly connected to the inner wall of the bottom protective shell 34.

[0036] When using this device, first insert the welding end 3 into the interior of the protective device 4. At this time, the rolling mechanism 6 under the extended outer disk 37 is inserted into the engaging groove 43 at the top of the sleeve shell 41, that is, the outer surface of the engaging rotating tooth 64 and the inner wall of the engaging groove 43 are connected to each other, and the bottom protective shell 34 is also inserted into the axis of the sleeve shell 41, and the bottom protective shell 34 is limited by the auxiliary roller shaft 44. At this time, the preparation work is completed.

[0037] The welding device 2 can move horizontally within the plane. When the compression sleeves 22 on both sides are contracted or elongated under the pressure control of the longitudinal controller 16, the outer cover tube 21 can be pushed longitudinally. The side pulling devices 14 on the left and right sides can control the sliding end plate 24 to slide left and right along the border of the control bottom frame 11 by pulling the traction belt 15.

[0038] When the welding device 2 moves to the designated position to prepare for welding, the outer push rod 33 is pressed downward first. At this time, the spring washer 36 is compressed, but the bottom end of the laser emitter 35 also slides downward from the inside of the bottom protective shell 34, and extends to the outside of the socket shell 41, and then releases a high-energy laser beam to the welding point for heating and welding.

[0039] During the welding process, the sleeve shell 41 sprays protective gas to the part where the bottom end of the laser emitter 35 slides out through the drainage device 7 on the outer surface for protection. However, it is obvious that the drainage device 7 provided in the device is relatively small, and there will be airflow gaps, resulting in contamination of the bottom end of the laser emitter 35. Therefore, the rolling mechanism 6 will continuously twist the meshing gear 64 through the bidirectional motor 62, forcing the external drainage device 7 to rotate at a high speed, so that the protective gas sprayed by the drainage device 7 can effectively cover the entire bottom end of the laser emitter 35.

[0040] During operation, the pressure pump 55 absorbs the inert protective gas through the drainage pipe 56 and pressurizes it into the interior of the gas dividing ring shell 51. Subsequently, the inert gas inside the gas dividing ring shell 51 is transported to the guide end 73 through the bent connecting pipe 71 under the action of the air pressure, so that the guide end 73 can continuously spray toward the bottom end of the laser emitter 35.

[0041] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of embodiment 1, the jet device 5 includes an air dividing ring shell 51, and the side of the inner cavity of the air dividing ring shell 51 close to the drainage device 7 is rotatably connected with a sliding inner ring 52 through an annular groove. The sliding inner ring 52 can rotate relative to the air dividing ring shell 51 and seals the sliding inner ring 52. The side of the inner cavity of the air dividing ring shell 51 away from the drainage device 7 is fixedly connected with a docking terminal 53 through a through-hole, and the end of the docking terminal 53 away from the air dividing ring shell 51 is fixedly connected with a filter block 54, the top of the filter block 54 is fixedly connected with a pressure pump 55, and the air inlet of the pressure pump 55 is fixedly connected with a drainage flow pipe 56.

[0042] The drainage device 7 includes a bending connecting tube 71, the bottom end of which is fixedly connected to a guide end 73, the bottom of the outer surface of the bending connecting tube 71 is sleeved with a limiting tube shell 72, the top of the limiting tube shell 72 is fixedly connected to a pressure-sensitive plug plate 75, the top of the inner wall of the pressure-sensitive plug plate 75 is slidably connected to a plug-in slide plate 74, and the sliding inner ring 52 is docked with the bending connecting tube 71. By setting the sliding inner ring 52, when the bending connecting tube 71 rotates, it will not cause torque interference to the air dividing ring shell 51.

[0043] The top end of the bending connecting tube 71 is fixedly connected to the inner cavity of the sliding inner ring 52 through an embedded chuck, and the top end of the bending connecting tube 71 extends to the interior of the air dividing ring shell 51. The side of the outer surface of the limiting tube shell 72 away from the bending connecting tube 71 is fixedly connected to the outer surface of the sleeve tube shell 41, and the side surface of the air dividing ring shell 51 is fixedly connected to the inner wall of the outer cover tube 21.

[0044] The containing frame 1 includes a control bottom frame 11, the inner cavity of the control bottom frame 11 is evenly provided with vertical push rods 12, the top of the vertical push rods 12 is provided with a welding plate 13, and the front and rear sides of the upper surface of the control bottom frame 11 are symmetrically provided with longitudinal controllers 16. The longitudinal controller 16 is a pressure control device that can pressurize the connected container by pumping air from the outside, and can also perform pressure extraction. A ventilation pipe 17 is fixedly connected to the output port of the longitudinal controller 16, and the left and right sides of the outer surface of the longitudinal controller 16 are fixedly connected to the side pulling device 14 through the traction belt 15.

[0045] The bottom of the side-pulling device 14 is fixedly connected to the upper surface of the control bottom frame 11, the lower surface of the longitudinal controller 16 is fixedly connected to the upper surface of the sliding end plate 24, the inner wall of the sliding end plate 24 is slidably connected to one side of the upper surface of the control bottom frame 11, and the end of the ventilation pipe 17 away from the longitudinal controller 16 is fixedly connected to the inner cavity of the plug-in guide plate 23.

[0046] When the sleeve tube shell 41 is twisted, the top part of the bent connecting tube 71 will drive the sliding inner ring 52 to rotate. Since the sliding inner ring 52 is rotatably connected to the inner wall of the air dividing ring shell 51, the sleeve tube shell 41 will not be hindered by the fixed air dividing ring shell 51 when rotating. When the sleeve tube shell 41 is twisted, the auxiliary roller 44 on the inner wall will roll relative to the bottom protective shell 34. Therefore, on the whole, when the device is working, only the internal protective device 4 rotates independently, and the outer cover tube 21 can effectively protect the self-rotation movement of the sleeve tube shell 41, and prevent the drainage device 7 from causing movement obstruction and incomplete coverage of the protective gas in the event of accidental external contact.

[0047] When the drainage device 7 is working, if the bending connecting tube 71 used to transport gas moves under the action of air pressure, the bending connecting tube 71 will definitely slide along the inner wall of the fixed limiting tube shell 72. At this time, the bending connecting tube 71 will drive the plug-in slide plate 74 to move relative to the fixed pressure-sensitive plug plate 75, so that the plug-in slide plate 74 can be plugged and slid along the inner wall of the pressure-sensitive plug plate 75, triggering the pressure-sensitive plug plate 75, so as to carry out maintenance work in time.

[0048] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
