Detailed implementation mode

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] Please refer to Figure 1 and Figures 4 to 6 As shown, the present invention provides a gas pressure gauge welding device, including a base 1 and a laser welding head 2 arranged on one side of the base 1. The laser welding head 2 is controlled by an external control mechanism. A driving mechanism 3 is arranged at the rear side of the top of the base 1. The driving mechanism 3 includes a first electric slide rail 31. A second electric slide rail 32 is arranged on the top of the base 1. The back of the first electric slide rail 31 is slidably arranged on the second electric slide rail 32 through a support plate 33. An electric push rod 34 connected to the second electric slide rail 32 is fixedly connected to the top of the base 1. Among them, the first electric slide rail 31 and the second electric slide rail 32 are prior arts, which are respectively used to drive the grinding wheel 7 to move up and down and move left and right;

[0030] A first motor 4 is slidably arranged on the surface of the first electric slide rail 31. The output end of the first motor 4 is fixedly connected to an output rod 5. One end of the output rod 5 is provided with a mounting rod 6 through a mounting component, and a grinding wheel 7 is fixedly connected to one end of the mounting rod 6. The mounting component is used for quickly replacing the grinding wheel 7;

[0031] The mounting component includes a first mounting plate 8 fixed on the surface of the mounting rod 6. A second mounting plate 9 is fixedly connected to the surface of the output rod 5. One side of the first mounting plate 8 is provided with a fixing rod 10 penetrating to the outside of the second mounting plate 9. A through groove 11 is opened inside the fixing rod 10. Sliding plates 12 are slidably arranged on both sides of the inner wall of the through groove 11. A spring 13 is fixedly connected between the two sliding plates 12. Convex blocks 14 are fixedly connected to the opposite sides of the two sliding plates 12. Handles 15 penetrating to the outside of the first mounting plate 8 are fixedly connected to one side of the two sliding plates 12. An activity groove penetrating to the inside of the fixing rod 10 is opened on the surface of the first mounting plate 8 for the handle 15 to move. A clamping block 16 is fixedly connected to one side of the mounting rod 6. A clamping groove 17 adapted to the clamping block 16 is opened at one end of the output rod 5.

[0032] With the above structure, after welding, the first electric slide rail 31 drives the grinding wheel 7 to move up and down, the second electric slide rail 32 drives the grinding wheel 7 to move left and right, and the electric push rod 34 drives the grinding wheel 7 to move back and forth, facilitating the adjustment of the grinding wheel 7 to the weld bead. The first motor 4 drives the grinding wheel 7 to rotate, and then the weld bead can be ground and removed.

[0033] By relatively pulling the two handles 15 in front of the first mounting plate 8, the two sliding plates 12 are driven to move relatively. The sliding plates 12 squeeze the springs 13, causing the bumps 14 to move into the through grooves 11, so that the fixing rod 10 can be moved out of the second mounting plate 9, separating the first mounting plate 8 from the second mounting plate 9. Then, the clamping blocks 16 are moved out of the clamping grooves 17 to disassemble the grinding wheel 7. Conversely, the grinding wheel 7 can be installed, facilitating the replacement of different grinding wheels 7 according to the size of the weld bead and improving the grinding accuracy.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, please refer to Figure 1 and Figure 4 As shown, the specific improvements are as follows: A dust collector 19 is fixedly arranged on the top of the base 1 through a frame 18, and an air inlet pipe 20 is connected to the air inlet of the dust collector 19. Both the air inlet pipe 20 and the air outlet pipe 22 are rubber hard pipes. One end of the air inlet pipe 20 is provided with a suction nozzle 21 through a cross pipe. The air outlet of the dust collector 19 is connected to a collection box 23 through the air outlet pipe 22, and the collection box 23 is arranged on one side of the frame 18 through a support plate.

[0036] With the above structure, when grinding, the dust collector 19 is started, and the dust is sucked through the air inlet pipe 20 and multiple suction nozzles 21, and then the dust is conveyed to the collection box 23 through the air outlet pipe 22, avoiding the accumulation of dust on the surface of the workpiece or in the surrounding environment and reducing the cleaning difficulty of subsequent workers.

[0037] Embodiment 3

[0038] Combining Embodiment 1 and Embodiment 2, please refer to Figures 1 to 3 As shown, the specific improvements are as follows: A hydraulic cylinder 24 is fixedly connected to the top of the frame 18, and the output end of the hydraulic cylinder 24 is fixedly connected to an annular plate 25. A sleeve 26 is arranged at the bottom of the annular plate 25. Screws 27 are fixedly connected to both sides of the bottom of the annular plate 25. The ends of the screws 27 passing through the outside of the sleeve 26 are threadedly connected with hand-tightening nuts 28. A clamping mechanism 29 is arranged on the top of the base 1;

[0039] The clamping mechanism 29 includes a fixed seat 291. A fixing plate 292 is fixedly connected to the rear side of the top of the fixed seat 291. One side of the inner wall of the fixed seat 291 is fixedly connected with a second motor 293, and the output end of the second motor 293 is fixedly connected with a bidirectional lead screw 294. Both sides of the surface of the bidirectional lead screw 294 are threadedly connected with vertical plates 295. The upper and lower sides of the vertical plates 295 are slidably connected to the inner wall of the fixed seat 291. Extension plates 296 are fixed to the opposite sides of the two vertical plates 295. The extension plates 296 penetrate to the outside of the fixed seat 291 and are fixedly connected with clamping plates 297. A servo motor 30 is fixedly arranged inside the base 1, and the output end of the servo motor 30 is fixedly connected to the bottom of the fixed seat 291 for driving the clamping mechanism 29 to rotate.

[0040] Through the setting of the above structure, place the watch case against the fixing plate 292 and between the two clamping plates 297. Start the second motor 293 to drive the bidirectional lead screw 294 to rotate. The two vertical plates 295 drive the two clamping plates 297 to move relatively on the bidirectional lead screw 294 to fixedly clamp the watch case. Then assemble the watch head on the watch case. The hydraulic cylinder 24 drives the sleeve 26 to cover downwards on the watch head to limit and press the watch head. Then the laser welding head 2 can be used to weld the connection between the watch head and the watch case. Drive the clamping mechanism 29 to rotate through the servo motor 30, which is convenient for the laser welding head 2 to automatically weld the four welding surfaces of the watch head and the watch case.

[0041] By unscrewing the hand-tightening nut 28 from the screw rod 27, the sleeve 26 and the annular plate 25 can be disassembled, so that the sleeve 26 can be correspondingly replaced according to the diameter of the watch head, which is convenient for limiting and pressing watch heads of different sizes and expands the application range of the device.
