[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The welding device for manufacturing mining machinery and equipment places the parts to be welded on the top of two moving boxes respectively, starts the first motor to drive the first screw to rotate, and drives the vertical plate and the top clamping plate to slide toward the U-shaped frame through the vertical plate connected by threads, so that the clamping plate and the U-shaped frame can quickly clamp and fix the parts of the mining machinery and equipment, thereby effectively improving the welding efficiency of the parts of the mining machinery and equipment and saving a lot of operation time.

[0017] 2. The welding device for manufacturing mining machinery and equipment, when the parts are pushed by the clamping plate, will first resist the first L-shaped rod to slide in the sliding groove of the sliding rod. When the first L-shaped rod slides to the end, the parts will resist the sliding rod, so that the sliding rod will slide toward the inside of the U-shaped frame while compressing the second spring, so that the inclined plate will rotate, and then the vertical limit of the first L-shaped plate by the moving box will make the first L-shaped plate slide vertically downward, and at the same time drive the bottom card plate downward. At the same time, that is, when the parts are clamped, the first screw drives the vertical plate to slide in the direction of the U-shaped frame, and the vertical plate drives the bottom card slot plate to slide at the same time. Then, when the card plate moves downward, until the card plate contacts and gets stuck with the card slot plate, the vertical plate cannot continue to slide, and the clamping plate cannot continue to apply clamping force to the mining machinery and equipment parts. At the same time, the card plate will contact the control switch downward, and then the control switch sends an electrical signal to the first motor to turn off the first motor, so that the first screw stops rotating. This can prevent some mining machinery and equipment parts with lower hardness from being over-clamped during the clamping process, causing deformation and unnecessary losses. The clamping force can be automatically controlled, which helps to improve the welding efficiency of mining machinery and equipment parts.

[0018] 3. The welding device for manufacturing mining machinery and equipment continuously contacts the spiral groove on the inner wall of the cylinder when the first L-shaped rod slides toward the U-shaped frame, and then the cylinder is continuously rotated to drive the first cam to rotate. When the protruding portion of the cam contacts the first contact plate, the first contact plate and the first push rod push the first piston downward. Then, when the protruding portion of the first cam does not contact the first contact plate, the third spring automatically drives the first contact plate upward to reset the first piston, and the reciprocating motion causes the first sealing cylinder to repeatedly inhale air through the suction pipe, and then squeeze it out from the intake hose into the jet plate, and then spray it out from the jet plate, so as to spray air to the dust on the surface of the parts of the mining machinery and equipment that need to be clamped. In addition, some small particles and gravel attached to the surface can be sprayed off, so that the dust on the parts of mining machinery and equipment can be removed before being clamped and fixed, so that the clamping effect of the parts of mining machinery and equipment is better, the clamping is more stable, and the welding process is stable, the two parts can be fitted more closely, and the welding effect is better. While the cylinder rotates, the driven rod can be driven to rotate at the same time through the synchronous belt, and then the other first cam is driven to cooperate with the various components on the first sealing cylinder, so that the two cleaning components in the moving box work at the same time, one side sprays from the jet plate, and the other side sprays from the jet hole of the clamping plate, so as to remove the dust and particulate matter on the surface of the parts of mining machinery and equipment in advance.

[0019] 4. The welding device for manufacturing mining machinery and equipment drives the first gear to rotate while the cylinder rotates. When the first gear rotates, it meshes with the second gear, thereby driving the second gear to rotate clockwise. When the second gear rotates clockwise, the fifth spring is squeezed by the internal rotating plate, so that the rotating plate is continuously disengaged from the locking teeth on the rotating rod when rotating, so that in the process of clamping the parts of the mining machinery and equipment, even if the cylinder drives the first gear to mesh with the second gear, the rotating rod will not rotate, and the protrusion of the second cam will not be driven to conflict with the second contact plate. That is, in the process of the first L-shaped rod being reset under the action of the first spring, the cylinder will be reversely rotated in the process of sliding outward from the inner wall of the spiral groove of the cylinder, thereby driving the first gear to rotate reversely and engage with the second gear. The wheels are meshed, so that the second gear rotates counterclockwise, so that the internal rotating plate contacts the latch tooth, and then the rotating rod can be rotated, thereby driving the second cam to rotate, and the protruding portion of the second cam contacts the second contact plate, so that the second contact plate drives the second push rod to push the second piston downward, and the fourth spring is compressed. Subsequently, when the protruding portion of the second cam does not contact the second contact plate, the fourth spring drives the second contact plate to reset, so that the second sealing cylinder repeatedly sucks water from the water bucket through the water suction pipe, and then repeatedly squeezes it into the water spray plate from the water inlet hose, so that after the welding of the parts of the mining machinery and equipment is completed, automatic water spraying for cooling is achieved to achieve the effect of rapid cooling. At the same time, some welding slag on the surface of the welded parts can be washed away by water flow, saving subsequent cleaning time.

[0020] 5. The welding device for manufacturing mining machinery and equipment can simultaneously drive the second L-shaped rod at the bottom to move during the resetting process of the first L-shaped plate, and then mesh the second gear on the ratchet pawl assembly through the tooth groove on the second L-shaped rod. In the process of the first L-shaped rod driving the second L-shaped rod to move, that is, in the process of clamping the mining machinery and equipment parts, even if the tooth groove on the second L-shaped rod meshes with the second gear, the connecting rod will not rotate. Only after the welding is completed and the first L-shaped rod is reset, the connecting rod will rotate. Therefore, when the water spray plate sprays water, the connecting rod drives the half gear to mesh with the rectangular rack frame. Under the action that the L-shaped telescopic scraper can only slide in the sliding hole of the moving box, the rectangular rack frame drives the L-shaped telescopic scraper to reciprocately scrape and push the residue generated by the welding on the top surface of the moving box to drop, and automatically remove the welding residue on the top of the moving box. Therefore, when the mining machinery and equipment parts are welded next time and need to be clamped, there is no need to clean the welding residue on the surface of the moving box in advance, which saves a lot of time and makes the welding efficiency higher.

[0043] In the present invention, when clamping and fixing the mining machinery and equipment parts 2, the parts to be welded are placed on the top of the two moving boxes 4 respectively, and then the first motor 6 is started to drive the first screw 504 to rotate, and the vertical plate 502 connected by the thread drives the vertical plate 502 and the top clamping plate 503 to slide in the direction of the U-shaped frame 501, so that the clamping plate 503 and the U-shaped frame 501 can quickly clamp and fix the mining machinery and equipment parts 2, thereby effectively improving the welding efficiency of the mining machinery and equipment parts 2 and saving a lot of operation time; the sliding hole on the top of the moving box 4 can guide the vertical plate 502 when it moves.

[0044] Example 2: Reference Figure 1-Figure 11, which is basically the same as the first embodiment, and further, two groups of moving boxes 4 are provided, and the two groups of moving boxes 4 are symmetrically arranged with respect to the center line of the workbench 1, a mounting groove is provided on the surface of the workbench 1, a bidirectional threaded rod 44 is rotatably connected in the mounting groove of the workbench 1, a third motor 45 is fixedly connected to one side of the workbench 1, an output end of the third motor 45 is fixedly connected to the bidirectional threaded rod 44, both ends of the bidirectional threaded rod 44 are threadedly connected with moving blocks 46, the two moving blocks 46 are slidably connected in the mounting groove of the workbench 1, and the top of the moving block 46 is fixedly connected to the moving box 4.

[0045] In the present invention, after the two mining machinery and equipment parts 2 are clamped, the third motor 45 is started to drive the bidirectional threaded rod 44 to rotate, so that the two moving blocks 46 drive the mining machinery and equipment parts 2 on the two moving boxes 4 to approach each other, thereby completing the docking between the two parts, and then performing subsequent welding.

[0046] A first bearing seat 505 for supporting the first screw 504 is fixedly installed on the inner wall of the moving box 4 close to the U-shaped frame 501, and the welding assembly 3 includes a support frame 301, and the support frame 301 is fixedly connected to the surface of the workbench 1, and a second motor 302 is fixedly installed on the top of the support frame 301, and the output end of the second motor 302 is fixedly connected to the second screw 303, and the second screw 303 is rotatably connected in the support frame 301, and a slider 304 is threadedly connected to the surface of the second screw 303, and an electric telescopic rod 305 is fixedly connected to the bottom of the slider 304, and a welding gun 306 is fixedly connected to the bottom of the electric telescopic rod 305, and a guide rod 307 is fixedly connected to the support frame 301, and the slider 304 is slidably connected to the guide rod 307.

[0047] In the present invention, after two mining machinery and equipment parts 2 that need to be welded are clamped and fixed, when they are docked between the two moving boxes 4, the second motor 302 is started to drive the second screw 303 to rotate, and the slider 304 is controlled to slide, driving the electric telescopic rod 305 and the welding gun 306 at the bottom to move to the appropriate position, and then the electric telescopic rod 305 is started to drive the welding gun 306 downward, so that the distance between the welding gun 306 and the parts can be adjusted, so as to perform welding, and the guide rod 307 is used to guide the slider 304.

[0048] Example 3: Reference Figure 1-Figure 15, which is basically the same as the first embodiment. Furthermore, the protection component 7 includes a sliding rod 701, which passes through the U-shaped frame 501 and is slidably connected to the U-shaped frame 501. A sliding groove is provided on the outer periphery of the sliding rod 701. A first L-shaped rod 8 is slidably connected in the sliding groove on the sliding rod 701. A second L-shaped rod 9 is fixedly connected to the bottom of the first L-shaped rod 8. The second L-shaped rod 9 passes through the moving box 4 and is slidably connected to the moving box 4. A circular block 10 is fixedly connected to the second L-shaped rod 9. A first spring 11 is sleeved on the second L-shaped rod 9. The two ends of the first spring 11 are respectively against the circular block 10 and the inner wall of the moving box 4.

[0049] In the present invention, during the process of clamping the mining machinery and equipment parts 2, the parts will first resist the first L-shaped rod 8 sliding into the sliding groove of the sliding rod 701 when the clamping plate 503 pushes them. The first L-shaped rod 8 first compresses the first spring 11 through the circular block 10. After welding is completed, the first spring 11 can automatically reset the first L-shaped rod 8.

[0050] One end of the slide bar 701 close to the interior of the moving box 4 is fixedly connected to a guide rod 702, which passes through the moving box 4 and is slidably connected to the moving box 4. A second spring 703 is sleeved on the surface of the guide rod 702. The two ends of the second spring 703 are respectively against the inner wall of the U-shaped frame 501 and the slide bar 701. The elastic force of the second spring 703 is greater than the elastic force of the first spring 11. The end of the slide bar 701 away from the first L-shaped rod 8 is hinged with an inclined plate 704, and the end of the inclined plate 704 away from the slide bar 701 is hinged with a first L-shaped plate 705. The first L-shaped plate 705 passes through the moving box 4 and is slidably connected to the moving box 4.

[0051] In the present invention, when the first L-shaped rod 8 slides to the end, the component will collide with the sliding rod 701, causing the sliding rod 701 to compress the second spring 703 while sliding toward the inside of the U-shaped frame 501, causing the inclined plate 704 to rotate, and then the first L-shaped plate 705 will slide vertically downward under the vertical limitation of the moving box 4 on the first L-shaped plate 705; because the elastic force of the second spring 703 is greater than the elastic force of the first spring 11, the sliding rod 701 will not slide when the component collide with the first L-shaped rod 8.

[0052] One end of the first L-shaped plate 705 away from the inclined plate 704 is hinged with a clamping plate 706, and the clamping plate 706 and the first L-shaped plate 705 are connected via a torsion spring 707. A baffle 708 is fixedly connected to the side of the first L-shaped plate 705 away from the torsion spring 707, and one end of the baffle 708 away from the first L-shaped plate 705 is against the clamping plate 706, and the lower end of the vertical plate 502 is fixedly connected to a slot plate 709 corresponding to the slot plate 706, and a plurality of control switches 710 are fixedly installed inside the slot plate 709, and the control switches 710 are electrically connected to the first motor 6.

[0053] In the present invention, when the first L-shaped plate 705 moves vertically downward, the bottom clamping plate 706 is driven downward at the same time. At the same time, that is, when the parts are clamped, the first screw 504 drives the vertical plate 502 to slide in the direction of the U-shaped frame 501. The vertical plate 502 drives the bottom card slot plate 709 to slide at the same time. Then, when the card plate 706 moves downward, until the card plate 706 contacts and gets stuck with the card slot plate 709, the vertical plate 502 cannot slide further at this time, and the clamping plate 503 cannot continue to apply the clamping force to the mining machinery and equipment parts 2. At the same time, the card plate 706 contacts the control switch 710 downward, and the control switch 710 sends an electrical signal to the first motor 6 to turn off the first motor 6, thereby making the first screw 50 4 stops further rotation, thereby being able to prevent some mining machinery and equipment parts 2 with low hardness from being over-clamped during the clamping process, causing deformation and unnecessary losses, and being able to automatically control the clamping force, thereby helping to improve the welding efficiency of the mining machinery and equipment parts 2; when the first motor 6 is started and the control clamp 503 is reset, the clamping plate 706 needs to be separated from the clamping slot plate 709, and the clamping plate 706 can automatically rotate and compress to one side of the torsion spring 707 and separate from the clamping slot plate 709; it should be noted that when the first motor 6 needs to be started again, the first motor 6 can be started again by simply pressing the start button on the external controller, without worrying about the first motor 6 being unable to start due to the contact between one end of the clamping plate 706 and the control switch 710.

The surface of the U-shaped frame 501 is provided with a receiving groove corresponding to the injection plate 15 and the first L-shaped rod 8.

[0056] In the present invention, the first push rod 1204 can only slide up and down in the first sealing cylinder 1202, and the bearing rod 13 can support the cylinder 14. When the first L-shaped rod 8 slides toward the U-shaped frame 501, it will continue to contact with the spiral groove 140 on the inner wall of the cylinder 14, and then the cylinder 14 will continue to rotate, thereby driving the first cam 1207 to rotate. When the protruding portion of the first cam 1207 contacts with the first contact plate 1205, the first contact plate 1205 and the first push rod 1204 will push the first piston 1203 downward. Then, when the protruding portion of the first cam 1207 does not contact with the first contact plate 1205, the third spring 1206 will make the first contact plate 1205 automatically push the first piston 1203 upward to reset, so that the reciprocating motion will cause the first sealing cylinder 1202 to repeatedly inhale air through the suction pipe 1208, and then squeeze it out from the intake hose 1209 into the In the jet plate 15, the dust on the surface of the mining machinery and equipment parts 2 that need to be clamped is blown away by a jet airflow, so that some small particles and small gravel attached to the surface can be blown away, so that the mining machinery and equipment parts 2 can be cleaned of dust before being clamped and fixed, so that the clamping effect of the mining machinery and equipment parts 2 is better, the clamping is more stable, and the welding process is stable, so that the two parts can fit more closely and the welding effect is better; through the accommodating groove on the surface of the U-shaped frame 501, when the mining machinery and equipment parts 2 are clamped, the jet plate 15 and the first L-shaped rod 8 enter, which will not affect the clamping effect of the parts; it should be noted that the air intake hose 1209 and the air intake pipe 1208 are both installed with a one-way valve, the purpose of which is to prevent the air from being sucked in from the air intake hose 1209 when the gas is inhaled, and to prevent the air from being squeezed out from the air intake pipe 1208 when the gas is squeezed out.

[0060] The ratchet pawl assembly 28 includes a rotating rod 29 rotatably connected to the bearing plate 27, the second cam 25 is fixedly connected to the rotating rod 29, the outer periphery of the rotating rod 29 is fixedly connected with a latch tooth 30, the surface of the rotating rod 29 is sleeved with a second gear 31, the second gear 31 is meshed with the first gear 26, the surface of the second gear 31 is provided with a through hole, a rotating plate 32 is hinged on the inner wall of the through hole of the second gear 31, a fifth spring 33 is fixedly connected between the rotating plate 32 and the inner wall of the through hole of the second gear 31, a fixed block 34 is fixedly connected to the inner wall of the second gear 31, the fixed block 34 is abutted against the rotating plate 32, the surface of the second L-shaped rod 9 is provided with a tooth groove, and the ratchet pawl assembly 28 includes a rotating rod 29 rotatably connected to the bearing plate 27, the second cam 25 is fixedly connected to the rotating rod 29, the second gear 31 is meshed with the first gear 26, the surface of the second gear 31 is provided with a through hole, and a rotating plate 32 is hinged on the inner wall of the through hole of the second gear 31, and a fifth spring 33 is fixedly connected between the rotating plate 32 and the inner wall of the through hole of the second gear 31, and a fixed block 34 is fixedly connected to the inner wall of the second gear 31. The fixed block 34 is against the rotating plate 32. The surface of the second L-shaped rod 9 is provided with a tooth groove. The wheel pawl assembly 28 is respectively arranged on one side of the tooth groove of the two second L-shaped rods 9 and one side of the first gear 26. A third bearing seat 35 is fixedly installed on the top wall of the moving box 4 near the tooth groove of the second L-shaped rod 9. The bottom of the third bearing seat 35 is rotatably connected with a connecting rod 36. The connecting rod 36 is fixedly connected to the rotating rod 29 on the ratchet pawl assembly 28 near the second L-shaped rod 9. A half gear 37 is fixedly connected to the connecting rod 36. A rectangular rack frame 38 is meshed on the outside of the half gear 37. An L-shaped telescopic scraper 39 is fixedly connected to one side of the rectangular rack frame 38. A sliding hole corresponding to the L-shaped telescopic scraper 39 is opened on the top wall of the moving box 4.

[0061] In the present invention, when the cylinder 14 rotates, it also drives the first gear 26 to rotate. When the first gear 26 rotates, it meshes with the second gear 31, thereby driving the second gear 31 to rotate clockwise. When the second gear 31 rotates clockwise, the fifth spring 33 is squeezed by the internal rotating plate 32, so that the rotating plate 32 is continuously disengaged from the locking teeth 30 on the rotating rod 29 when rotating, so that in the process of clamping the mining machinery and equipment parts 2, even if the cylinder 14 drives the first gear 26 to mesh with the second gear 31, the rotating rod 29 will not rotate, and the protruding portion of the second cam 25 will not be driven to engage with the second contact plate 23. After the welding of the mining machinery and equipment parts 2 is completed, the surface temperature is very high, and there will be some welding slag remaining on the top surface of the moving box 4. If it is not cleaned in time, it will affect the clamping effect of the next time and reduce the welding efficiency. Therefore, after the welding is completed, that is, in the process of the first L-shaped rod 8 being reset under the action of the first spring 11, the cylinder 14 will be caused to rotate in the opposite direction during the process of sliding outward from the inner wall of the spiral groove 140 of the cylinder 14, thereby driving the first gear 26 to rotate in the opposite direction and mesh with the second gear 31, so that the second gear 31 rotates counterclockwise, so that the internal rotating plate 32 and the card The tooth 30 is in conflict with each other, so that the rotating rod 29 can be rotated, thereby driving the second cam 25 to rotate, and the protruding portion of the second cam 25 is in conflict with the second contact plate 23, so that the second contact plate 23 drives the second push rod 22 to push the second piston 21 downward, and the fourth spring 24 is compressed. Subsequently, when the protruding portion of the second cam 25 does not conflict with the second contact plate 23, the fourth spring 24 drives the second contact plate 23 to reset, and the reciprocating motion is performed, so that the second sealing cylinder 20 repeatedly sucks water from the water bucket 40 through the water suction pipe 41, and then repeatedly squeezes it into the water spray plate 42 from the water inlet hose 43, so as to achieve the mining machinery and equipment. After the welding of the component 2 is completed, water is automatically sprayed to cool it down, so as to achieve the effect of rapid cooling. It should be noted that the stainless steel material can be quickly cooled by pouring water on the weld during welding. This cooling method will not cause the workpiece to crack or affect the quality of welding due to sudden temperature changes. At the same time, some welding slag on the surface of the welded component can be washed away by the water flow, saving the time for subsequent cleaning. It should be noted that a one-way valve is installed inside the water inlet hose 43 and the water suction pipe 41, so as to prevent the gas from being sucked in from the water inlet hose 43 when inhaling, and to prevent the gas from being squeezed out from the water suction pipe 41 when squeezing out.During the resetting process of the first L-shaped rod 8, the second L-shaped rod 9 at the bottom will also be driven to move, and then the tooth groove on the second L-shaped rod 9 will mesh with the second gear 31 on the ratchet pawl assembly 28. During the process of the first L-shaped rod 8 driving the second L-shaped rod 9 to move, that is, during the clamping process of the mining machinery and equipment parts 2, even if the tooth groove on the second L-shaped rod 9 meshes with the second gear 31, the connecting rod 36 will not rotate. Only after the welding is completed and the first L-shaped rod 8 is reset, the connecting rod 36 will be rotated. Therefore, when the water spray plate 42 sprays water, the connecting rod 36 drives the half gear 37 to mesh with the rectangular rack frame 38. Under the action that the L-shaped telescopic scraper 39 can only slide in the sliding hole of the moving box 4, the rectangular rack frame 38 drives the L-shaped telescopic scraper 39 to reciprocately scrape and push the residue generated by the welding on the top surface of the moving box 4, so as to automatically remove the residue. The welding residue on the top of the moving box 4 is removed, so that the welding residue on the surface of the moving box 4 does not need to be cleaned in advance when the mining machinery and equipment parts 2 are welded and clamped next time, which saves a lot of time and makes the welding efficiency higher; it should be noted that after the welding of the mining machinery and equipment parts 2 is completed, the first motor 6 is controlled to rotate in the opposite direction for a short distance, that is, the clamping plate 503 is separated from the parts a little, and then the welded mining machinery and equipment parts 2 are grabbed upward by the manipulator, lifted to be separated from the first L-shaped rod 8, and then stopped; the L-shaped telescopic scraper 39 can automatically retract and adjust the distance during scraping, which will not be affected by the distance between the clamping plate 503 and the U-shaped frame 501; it should be noted that the rotating rod 29 is fixedly connected with retaining rings on both sides of the second gear 31 to limit the second gear 31 and prevent the second gear 31 from moving at will. ;
