DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, the present invention provides a high-efficiency welding device for mechanical and electrical equipment, including a base 1, a driving structure 2 is fixedly installed on the top of the base 1, and a laser generator 3 is connected to the top of the driving structure 2 in a transmission manner. The driving structure 2 and the laser generator 3 are both conventional technical solutions in the prior art and are not described in detail here. A connecting plate 4 is provided on the top of the base 1, and an upper clamping plate 7 and a lower clamping plate 10 are provided on one side of the connecting plate 4 close to the center of the base 1. A support plate 8 is fixedly installed on one end of the upper clamping plate 7 close to the center of the base 1, and a telescopic rod 5 and a spring 6 are fixedly installed on one side of the upper clamping plate 7 and the lower clamping plate 10 close to the connecting plate 4, and a slide seat 9 is slidably connected to the rear side of the connecting plate 4;

[0029] A motor 11 is fixedly installed at the top of the inner cavity of the base 1, and a lead screw 14 is rotatably connected to the top of the inner cavity of the base 1. A transmission wheel 12 is fixedly sleeved on the right end of the lead screw 14 and the output end of the motor 11. A transmission belt 13 is transmission-connected to the surface of the transmission wheel 12. An engaging block 15 is meshed on the surface of the lead screw 14. The meshing block 15 has a nut and a steel ball built in it and is used in conjunction with the lead screw 14. This is a prior art. A rotating rod 16 is rotatably connected to the top of the engaging block 15. A cleaning wheel 17 is fixedly installed on the top of the rotating rod 16. A gear 18 is fixedly installed on the middle of the rotating rod 16. A rack 19 is provided on the top of the base 1.

[0030] By arranging a cleaning wheel 17 on the base 1, after the plate is installed in place, the motor 11 is started to drive the screw 14 to rotate, and the meshing of the screw 14 and the meshing block 15 drives the meshing block 15 to move left. Since the gear 18 and the rack 19 are meshed, the cleaning wheel 17 will rotate during the process of the meshing block 15 moving left, and then the welding position of the plate located on the upper and lower surfaces of the cleaning wheel 17 will be cleaned and wiped, thereby realizing automatic cleaning of the plate before welding, and the operation is simple and convenient.

[0031] Among them, the telescopic rod 5 and the spring 6 fixed to the upper clamping plate 7 are fixedly installed on the slide seat 9, and the telescopic rod 5 and the spring 6 connected to the lower clamping plate 10 are fixedly installed at the front end of the connecting plate 4;

[0032] By arranging the slide seat 9 to slide on the connecting plate 4, it can be achieved that after the upper clamping plate 7 positions the workpiece, it can also drive the workpiece to move up and down, so that the workpiece is fitted.

[0033] The top of the engagement block 15 is fixedly mounted with a slider 20, which is in an "L" shape and is slidably connected to the top of the inner cavity of the base 1;

[0034] By providing the slider 20 , the slider 20 positions and guides the movement of the engagement block 15 , thereby preventing the engagement block 15 and the lead screw 14 from rotating with each other.

[0035] The gear 18 is meshed with the rack 19, the cleaning wheel 17 is located above the base 1, and the cleaning wheel 17 is fixed to the rotating rod 16 by a threaded detachable connection;

[0036] After long-term use, the cleaning wheel 17 can be disassembled for cleaning or replacement to ensure the cleaning effect. At the same time, the cleaning wheel 17 is connected to the engaging block 15 through the rotating rod 16. A sliding groove is provided on the engaging block 15. The rotating rod 16 can slide in the front and rear directions, and can also slide on the engaging block 15, but cannot bend or move left and right.

[0037] The lead screw 14 passes through the connecting plate 4 but does not contact the connecting plate 4. There are two lower clamping plates 10. The length of the lead screw 14 is greater than the distance between the two lower clamping plates 10.

[0038] The movement of the engaging block 15 is prevented from interfering with the connecting plate 4, thereby ensuring the normal operation of the device and allowing the cleaning wheel 17 to smoothly leave the plate.

[0039] Among them, a telescopic rod 21 and a spring 22 are fixedly installed on the rear side of the rack 19, and the rear ends of the telescopic rod 21 and the spring 22 are fixedly connected to the base 1;

[0040] By installing spring 22 between the rear side of rack 19 and base 1, after welding is completed, lead screw 14 reverses, driving cleaning wheel 17 to move to the right. At this time, since the parts of mechanical and electrical equipment have been welded, when cleaning wheel 17 moves in the opposite direction, it will first contact with the workpiece, and then push cleaning wheel 17 backward, so that cleaning wheel 17 contacts with the rear side of welded part. At this time, spring 22 is in a compressed state, exerting forward pressure on cleaning wheel 17, transferring pressure to welded part, exerting pressure on welded part, realizing pressure detection of welded part, and avoiding the occurrence of cold welding.

[0041] The connecting plate 4 is slidably connected to the base 1, the bottom end of the connecting plate 4 penetrates and extends into the inner cavity of the base 1, and a positioning piece is fixedly installed on the connecting plate 4;

[0042] The connection plate 4 is provided with a positioning piece which is slidably connected with the base 1 , so as to realize positioning and guiding the movement of the connection plate 4 and ensure the stability of the movement of the connection plate 4 .

[0043] Among them, a telescopic rod 3 23 and a spring 3 24 are fixedly installed at one end of the connecting plate 4 away from the center of the base 1, and the telescopic rod 3 23 and the spring 3 24 are fixedly connected to the base 1. A push rod 25 is fixedly installed at one end of the connecting plate 4 close to the center of the base 1. A bottom box 26 and a top box 29 are fixedly installed at the top of the inner cavity of the base 1. A lifting rod 27 is slidably connected to the inner cavity of the bottom box 26. A push block 28 is fixedly installed at the top of the lifting rod 27. A push shaft 30 is slidably connected to the inner cavity of the top box 29. A connecting pipe 31 is fixedly connected between the top box 29 and the bottom box 26.

[0044] By arranging a push rod 25 at the bottom of the connecting plate 4, when the engaging block 15 moves to the right and contacts the push shaft 30, the push shaft 30 will be pushed to the right, and the hydraulic oil in the push shaft 30 will be transported to the bottom box 26 through the connecting pipe 31, so that the lifting rod 27 drives the push block 28 to move upward, and pushes the push rod 25 to the side away from the center of the base 1, thereby driving the connecting plate 4 away from the workpiece, and making the lower clamping plate 10 leave the workpiece, thereby realizing automatic unloading.

[0045] The push block 28 is in the shape of an isosceles trapezoid, and one end of the push rod 25 close to the push block 28 is an inclined surface, which fits with the two sides of the isosceles trapezoid;

[0046] The push block 28, which is set to be an isosceles trapezoid, can push the push rod 25 away through the guidance of its inclined surface. When the engaging block 15 is separated from the push shaft 30, the spring three 24 in a compressed state can push the connecting plate 4 back to reset under the action of elasticity, thereby driving the push rod 25 to move in the opposite direction, pushing the push block 28 down, causing the hydraulic oil to reflux, and resetting the push shaft 30.

[0047] The cross-sectional shape of the push shaft 30 is an “I” shape, the left end of the push shaft 30 is located on the left side of the top box 29, the push shaft 30 is located above the lead screw 14, and the projection of the push shaft 30 in the vertical direction intersects with the meshing block 15;

[0048] By setting the push shaft 30 in an “I” shape, the contact area with the engagement block 15 can be increased, ensuring that the rightward movement of the engagement block 15 can smoothly push the push shaft 30 .

[0049] The working principle and use process of the present invention:

[0050] When in use, first place two plates on the lower clamping plate 10 and the upper clamping plate 7 respectively. When placing, move the lower clamping plate 10 and the upper clamping plate 7 to the side away from the center of the base 1, and then place the plates on the base 1 and the support plate 8, then release the lower clamping plate 10 and the upper clamping plate 7, the elasticity of the spring 16 will drive the lower clamping plate 10 and the upper clamping plate 7 to clamp the plates, and at this time the vertical plates are located above the cleaning wheel 17;

[0051] Then, the motor 11 is started, and the motor 11 drives the lead screw 14 to rotate through the transmission wheel 12 and the transmission belt 13, thereby driving the meshing block 15 on the lead screw 14 to move to the left. When the meshing block 15 moves to the left, the meshing of the gear 18 and the rack 19 can drive the cleaning wheel 17 to move to the left while rotating. Since the upper and lower surfaces of the cleaning wheel 17 are in contact with the welding positions of the two plates respectively, the welding positions can be cleaned during the movement of the cleaning wheel 17.

[0052] When the cleaning wheel 17 leaves the plate, the vertical plate loses the support of the cleaning wheel 17 and falls downward under the action of gravity, so that the welding positions of the two plates are in contact. At this time, the driving structure 2 drives the laser generator 3 to move along the welding position, and the laser generator 3 emits a laser to hit the welding position, thereby realizing the welding of the two plates. In this process, when the plate is thin, the upper clamping plate 7 does not need to be opened, and when the plate is thick and cannot be pushed to deform, the upper clamping plate 7 needs to be opened;

[0053] After welding is completed, the lead screw 14 reverses, driving the meshing block 15 to move in the opposite direction. When the cleaning wheel 17 contacts the workpiece, it will be guided to the rear side of the workpiece by the workpiece and contact the workpiece. At this time, the spring 22 is in a compressed state, and pressure is applied to the welding position through the rack 19 and the cleaning wheel 17. However, if the welding is not firm, the cleaning wheel 17 will push the welding position, thereby realizing the detection of welding quality.

[0054] When the cleaning wheel 17 moves to the right and is separated from the workpiece, the engaging block 15 contacts the push shaft 30, pushing the push shaft 30 to the right, and then the hydraulic oil in the push shaft 30 is transported to the bottom box 26 through the connecting pipe 31, so that the lifting rod 27 drives the push block 28 to move upward, and pushes the push rod 25 to the side away from the center of the base 1, thereby driving the connecting plate 4 away from the workpiece, and making the lower clamping plate 10 leave the workpiece to realize unloading.
