[0027] Example 1, please refer to Figure 1-Figure 5 The present embodiment provides a fixture for quickly locking a workpiece, comprising a support frame 1; an electric slide rail 2, which is fixedly mounted on the upper end of the support frame 1, and the electric slide rail 2 realizes the left and right movement of a rectangular frame 3 through an electric control system, thereby adjusting the left and right position of the workpiece; a rectangular frame 3, which is slidably connected to the outer wall of the electric slide rail 2; The outer wall of the rectangular frame 3 is rotatably connected to the ratchet 41, the ring gear 42, and the linkage gear 43. The inner wall of the ring gear 42 is hinged with a pawl 44 through a pin, and a torsion spring is provided on the outside of the pin. The inner wall of the rectangular frame 3 is rotatably connected to two reciprocating screws 45, and the other end of the reciprocating screw 45 movably passes through the rectangular frame 3 and is fixedly connected to the ratchet 41 and the linkage gear 43 respectively. The outer walls of the two reciprocating screws 45 are threadedly connected to moving blocks 46. The upper end of the moving block 46 on one side is hinged with a connecting rod 418, and the upper end of the connecting rod 418 is provided with a through groove, and the upper end of the moving block 46 on the other side is slidably connected to the inside of the through groove. The middle part of the connecting rod 418 is slidably penetrated by a mounting shaft 47, and the top of the mounting shaft 47 is fixedly connected to a fixed platform 48. The bottom of the mounting shaft 47 is rotatably connected to a moving rod 49, and a roller 414 is provided at the bottom of the moving rod 49. The moving rod 49 and the roller 414 work together to adjust the height of the workpiece. Rollers 414 provide support at the bottom of the workpiece, facilitating precise adjustment by accommodating the movement of the movable rod 49. A movable plate 410 is mounted on the side of the rectangular frame 3. The lower end of the movable plate 410 has an opening, within which an adjustment plate 411 is slidably connected. An electric telescopic rod 412 is fixedly connected to the inside of the movable plate 410. The output end of the electric telescopic rod 412 is fixedly connected to a connecting block 413, the upper end of which is fixedly connected to the adjustment plate 411. A chute A417 is defined on the side of the rectangular frame 3, with one end of the movable plate 410 slidingly connected within the interior of the chute A417. A chute B415 is defined on the inside of the movable plate 410. A connecting shaft 416 is fixedly connected to the side of the movable rod 49, with the end of the connecting shaft 416 away from the movable rod 49 slidingly connected within the interior of the chute B415. Two stopper plates 419 are fixedly connected to the inner wall of the rectangular frame 3, with the movable rod 49 slidably connected between the two stopper plates 419. The interior and outer walls of the rectangular frame 3 are provided with cleaning components 5 , and the outer wall of the support frame 1 is equipped with a blowing component 6 .

[0028] When in use, first place the workpiece to be welded on the upper end of the fixed table 48, and then the workpiece can be clamped and fixed by the clamping parts on the side of the workpiece, and then the workpiece can be welded. When the left and right positions of the workpiece are required, the electric slide rail 2 can drive the rectangular frame 3 to move left and right, and then the left and right positions can be adjusted. When the front and back positions of the workpiece need to be adjusted, the external motor drives the ratchet 41 to rotate counterclockwise to adjust the front and back positions of the workpiece. Figure 3From this perspective, at this time, with the cooperation of the pawl 44 inside the ring gear 42, the ring gear 42 will rotate along with the ratchet 41, and the linked gear 43 meshing with it will also rotate accordingly. Then the ratchet 41 and the linked gear 43 will respectively drive the two reciprocating screws 45 to rotate, and the thread directions of the two reciprocating screws 45 are opposite, so the moving blocks 46 threadedly connected to the outer walls of the two reciprocating screws 45 will move in one direction at the same time, and the moving block 46 will drive the connecting rod 418 to move at the same time, and then drive the mounting shaft 47 to move, and then the fixed platform 48 on the top of the mounting shaft 47 will also move accordingly, so that the front and rear position of the workpiece can be adjusted. When the workpiece needs to be rotated, the motor drives the ratchet 41 to rotate clockwise. At this time, the ring gear 42 no longer rotates, and then only the reciprocating screw 45 connected to the side of the ratchet 41 will rotate, and then the moving block 46 located on its outer wall will move accordingly, while the moving block 46 on the other side remains stationary, and then the moving block 46 on this side will pass through the upper end The pin drives the connecting rod 418 to rotate, which in turn drives the installation shaft 47 to rotate. At the same time, when the installation shaft 47 moves, it drives the moving rod 49 and the roller 414 at the bottom to move. Since one end of the connecting shaft 416 fixedly connected to the outer wall of the moving rod 49 is slidably connected to the inside of the slide groove B415 opened on the side of the moving plate 410, the moving rod 49 will drive the moving plate 410 to move through the connecting shaft 416 during the movement. When the moving plate 410 moves, one end of it will slide inside the slide groove A417, thereby ensuring its movement stability. When the height of the workpiece needs to be adjusted, the electric telescopic rod 412 can be started to pull the adjustment plate 411 to move toward the outer end inside the opening through the connecting block 413. Then, the side where the roller 414 at the bottom of the moving rod 49 contacts the adjustment plate 411 will have a plane that becomes an inclined upward surface, so that the moving rod 49 will be lifted, thereby causing the installation shaft 47 to rise, and then the installation shaft 47 can drive the fixed platform 48 at the top to rise.

[0029] Example 2, please refer to Figures 1-6On the basis of Example 1, the cleaning component 5 includes a slag guide plate 51, which is fixedly connected to the inner wall of the rectangular frame 3, one end of the reciprocating screw rod 45 is fixedly connected to the transmission shaft 52, and the other end of the transmission shaft 52 is fixedly connected to the rotating block 53. The outer wall of the rotating block 53 is rotatably connected to the connecting rod A54 through a pin shaft, the outer wall of the rectangular frame 3 is fixedly connected to the rotating shaft A55, and the outer wall of the rotating shaft A55 is fixedly sleeved with a swing rod 56 and a movable rod 57. The two ends of the movable rod 57 are rotatably connected to the connecting rod B58 through a pin shaft, and the other end of the connecting rod B58 is hinged to a movable plate 59. The surface of the slag guide plate 51 is slidably connected to a scraper 512, and one side of the scraper 512 is fixedly connected to a sliding shaft 513. The cleaning assembly 5 further includes a movable groove A511 and a movable groove B510. The movable groove A511 is formed on the side of the rectangular frame 3, and the movable groove B510 is formed on the outer wall of the movable plate 59. The sliding shaft 513 is slidably connected to the movable groove A511 and the movable groove B510. The end of the connecting rod A54 away from the rotating block 53 is hingedly connected to the swing arm 56.

[0030] When in use, the waste and residue generated in the process of processing the workpiece will fall to the upper end of the slag guide plate 51. When the reciprocating screw 45 fixedly connected to the ratchet 41 rotates, it will drive the transmission shaft 52 to rotate, and the transmission shaft 52 will drive the rotating block 53 to rotate, and then the rotating block 53 will drive one end of the connecting rod A54 hinged thereto to rotate around the transmission shaft 52. At the same time, the other end of the connecting rod A54 will drive the swing rod 56 and the rotating shaft A55 to swing left and right. When the rotating shaft A55 swings, it will drive the movable rod 57 to rotate. When the movable rod 57 rotates, The movable plate 59 will be pulled to move through the connecting rod B58 hinged at both ends. Since the movable rod 57 is in a left and right swinging state, the connecting rod B58 will pull the movable plates 59 on both sides to swing left and right. Then, since the sliding shaft 513 is slidably connected to the inside of the movable groove B510 opened on the outer wall of the movable plate 59, when the movable plate 59 moves, it will drive the sliding shaft 513 to slide back and forth inside the movable groove A511, and the scraper 512 at the other end of the sliding shaft 513 can scrape off the residue generated during the processing of the upper end of the slag guide plate 51.

[0031] Example 3, please refer to Figure 1-Figure 7Based on Example 1, the blowing assembly 6 includes a receiving frame 61, which is fixedly connected to the outer wall of the support frame 1. An airbag 63 is provided inside the receiving frame 61. The air inlet and air outlet of the airbag 63 are respectively equipped with an air inlet pipe 62 and an air supply pipe 64. An extrusion plate 65 is slidably connected to the interior of the receiving frame 61. The airbag 63 is pressurized and stores gas through the extrusion plate 65. A one-way valve controls the one-way output of the airflow. An extrusion rod 66 is fixedly connected to the outer wall of the extrusion plate 65. A mounting block 67 is fixedly sleeved on the outer wall of the extrusion rod 66. The upper end of the mounting block 67 is fixedly connected to a connecting pipe 68. The air outlet of the connecting pipe 68 is equipped with a blowing ring 69. The other end of the air supply pipe 64 is fixedly connected to the air inlet of the connecting pipe 68. A limit block 610 is fixedly connected to the outer wall of the receiving frame 61. One-way valves are provided inside the air inlet pipe 62 and the air supply pipe 64.

[0032] During use, when the moving rod 49 moves, it will push the squeezing rod 66, and then the squeezing rod 66 will push the squeezing plate 65 toward the inside of the accommodating frame 61. Then, the squeezing plate 65 will squeeze the airbag 63 while moving. Since the one-way valve inside the air inlet pipe 62 only allows gas to enter, after the airbag 63 is squeezed, the gas inside it will be transported to the connecting pipe 68 through the air supply pipe 64, and then transported to the blowing ring 69 through the connecting pipe 68, and then blown out, so that the outer wall of the reciprocating screw rod 45 can be blown and cleaned. At the same time, since the connecting pipe 68 is fixed to the upper end of the mounting block 67, and the mounting block 67 moves with the movement of the squeezing rod 66, the blowing ring 69 can be moved along with the movement of the moving rod 49, thereby avoiding affecting the movement of the moving block 46. After the squeezing plate 65 is reset, it will inhale through the air inlet pipe 62 under the action of the elastic force of the airbag 63 itself.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
