Description

Technical Field

[0001] This invention relates to the field of laser processing hardware machinery and equipment, specifically to a laser processing hardware machinery and equipment. Background Technology

[0002] Hardware parts are typically subjected to a series of physical or chemical treatments during production to change their shape, size, performance, or appearance, ultimately creating parts or products that meet the requirements. Hardware production usually requires the use of laser processing hardware machinery and equipment to combine multiple parts into one. The most commonly used equipment in laser processing hardware machinery and equipment is the laser welding machine, which is used for welding.

[0003] Existing laser welding is usually used in conjunction with a wire feeder. The wire feeder feeds the welding wire to the end of the welding gun for welding of hardware. The welding wire selected varies depending on the hardware, so different types of wire feed rollers need to be used for different welding wires. The existing wire feed rollers are fixed to the outer wall of the rotating rod with bolts. When the wire feed rollers need to be disassembled, the two sets of bolts must first be removed from the end of the rotating rod, and then the wire feed rollers must be replaced. Moreover, the bolts need to be tightened during installation, making the bolt disassembly method quite cumbersome. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a laser processing hardware machinery and equipment to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser processing hardware machinery equipment, comprising a laser welding machine body and a wire feeder body. The top of the laser welding machine body is provided with a wire feeder body, and an installation groove is formed inside the wire feeder body. A cabinet door is movably installed on the inner wall of the installation groove. A locking assembly is provided inside the cabinet door, and a first limiting block and a second limiting block are fixed to one side of the cabinet door. A mounting seat is installed inside the installation groove by bolts, and a horizontal plate is installed at the top of the inner wall of the installation groove. A guide frame is fixed to the bottom of the horizontal plate, and a limiting plate is movably installed on one side of the guide frame. A pressing block is fixed to one side of the device. A lead screw is installed inside the limiting plate, and a connecting rod is fixed to the end of the lead screw. A mounting bracket is movably installed at the end of the connecting rod. A pressure roller is provided inside the mounting bracket, and a third gear is installed on one side of the pressure roller. A groove is opened inside the mounting base, and a shaft is movably installed on the inner wall of the guide wire groove. A second gear is fixed to the end of the shaft. A first gear is installed on one side of the mounting base, and a driving structure is provided on one side of the mounting base. A sliding rod is fixed to one side of the mounting base, and a support rod is movably installed on the outer wall of the sliding rod. Pressing rings are installed at both ends of the support rod through bearings.

[0006] By adopting the above technical solution, the problem of inconvenient replacement of existing wire feeding wheels is solved. With the support rod and compression ring, when it is necessary to replace two sets of wire feeding wheels, the support rod is pulled outward to separate the compression ring from the wire feeding wheel. Then, the support rod is rotated more than 90°. At this time, the support rod is no longer on the movement trajectory of the wire feeding wheel, so the wire feeding wheel can be removed, replacing the method of bolt tightening. When the cabinet door is closed, the second limit block compresses the support rod to achieve the purpose of compressing the support rod, thereby causing the compression ring to compress the wire feeding wheel. The rubber pad can increase the friction between the compression ring and the blocking plate and the wire feeding wheel, so that the rotation of the shaft can drive the wire feeding wheel to rotate.

[0007] The present invention is further configured such that a guide rod is fixed to the top of the limiting plate, and the guide frame has a vertical groove and an inclined groove inside.

[0008] Preferably, the outer wall of the guide rod fits into the inner wall of the vertical groove and the inner wall of the inclined groove, and the vertical groove and the inclined groove cooperate with the guide rod to limit the direction of movement of the guide rod.

[0009] The present invention is further configured such that the engaging assembly includes a sliding groove and a stop bar, a sliding groove is provided on one side of the cabinet door, and a stop bar is movably installed on the inner wall of the sliding groove, a fixing rod is fixed on the inner wall of the sliding groove, and a spring is sleeved on the outer wall of the fixing rod, and a limit hole is provided on one side of the inner wall of the mounting groove.

[0010] Preferably, the protrusion is first pushed manually, and the protrusion slides on the inner wall of the transverse groove. When the protrusion moves, it will drive the stop rod fixed to it to move. The stop rod slides on the inner wall of the slide groove. When the stop rod moves, it will squeeze the spring. Then the protrusion is released, and the spring drives the stop rod to return to its original position. The stop rod enters the inner wall of the limiting hole, thereby achieving the purpose of limiting the cabinet door.

[0011] The invention is further configured such that a protrusion is fixed on one side of the stop bar, and a horizontal groove is provided inside the cabinet door.

[0012] Preferably, the protrusions are designed to facilitate pushing by personnel, allowing the protrusions to slide on the inner wall of the transverse groove.

[0013] The present invention is further configured such that a rubber pad is fixed on one side of the extrusion ring, and an avoidance groove is provided on one side of the extrusion ring, and the inner wall diameter of the avoidance groove is larger than that of the shaft.

[0014] Preferably, the rubber pad can increase the friction between the roller and the wire feeding wheel, so that the shaft rotates with a certain force.

[0015] The invention is further configured such that a rotating groove is provided inside the support rod, and a limiting groove is provided on one side of the inner wall of the rotating groove, and a locking block is fixed to the outer wall of the slide rod.

[0016] Preferably, the groove can fit against the outer wall of the slide bar, allowing the support rod to rotate around the slide bar. The limiting groove can cooperate with the locking block to limit the rotation angle of the support rod.

[0017] The present invention is further configured such that a guide post is fixed to the top of the mounting bracket, and the guide post passes through the limiting plate; a vertical rod is movably installed on the top of the guide post, and a fixing plate is fixed to one side of the vertical rod; a sleeve rod is fixed to the top of the limiting plate, and the outer wall of the sleeve rod has a slot and a scale line.

[0018] Preferably, the fixing plate can be located on the inner wall of the slot, thus penetrating the position of the fixing plate and the scale line, thereby changing the clamping of welding wires of different diameters, and the vertical rod can be easily disassembled from the guide column.

[0019] The present invention is further configured such that a protruding rod is fixed at the bottom of the vertical rod, and a guide hole is provided at the top of the guide post.

[0020] Preferably, the protruding rod can be inserted into the inner wall of the guide hole. The diameter of the vertical rod is smaller than the diameter of the guide post. The vertical rod does not contact the inner wall of the sleeve rod, so that the vertical rod will not contact the sleeve rod when it moves, which can reduce friction. The vertical rod can be easily installed at the end of the guide post.

[0021] The present invention is further configured such that one side of the bottom of the first limiting block is provided with an inclined surface, and one side of the top of the extrusion block is provided with an inclined surface.

[0022] Preferably, the inclined extrusion block contacts the first limiting block, thereby enabling the first limiting block to limit the extrusion block and preventing the limiting plate from shaking during operation.

[0023] The present invention is further configured such that a stop block is fixed at the end of the slide rod, and the diameter of the stop block is larger than that of the slide rod.

[0024] Preferably, the support rod can be limited by the stop block to prevent it from detaching from the slide bar.

[0025] In summary, the present invention has the following main beneficial effects: 1. This invention solves the problem of inconvenient replacement of existing wire feeding wheels by incorporating a sliding rod, a locking block, a support rod, a squeezing ring groove, and a limiting groove. Through the support rod and squeezing ring, when two sets of wire feeding wheels need to be replaced, the support rod is pulled outwards to separate the squeezing ring from the wire feeding wheel. Then, the support rod is rotated more than 90°, at which point it is no longer on the trajectory of the wire feeding wheel, allowing the wire feeding wheel to be removed. This replaces the bolt tightening method. When the cabinet door is closed, the second limiting block squeezes the support rod, achieving the purpose of squeezing the support rod, thereby causing the squeezing ring to squeeze the wire feeding wheel. The rubber pad increases the friction between the squeezing ring and the blocking disc and the wire feeding wheel, enabling the shaft to rotate and drive the wire feeding wheel to rotate.

[0026] 2. This invention, by setting a first limiting block, a second limiting block, and a guide frame, uses the cooperation of the first and second limiting blocks to limit the limiting plate when the cabinet door is closed, preventing the limiting plate from shaking during use. The guide frame allows the compression ring to contact the mounting frame when the support rod rotates, thus pressing the mounting frame upwards. Under the action of the vertical and inclined grooves, the limiting plate can move obliquely upwards, making the rotation of the support rod easier and improving work efficiency. The cooperation between the locking block and the limiting groove allows the support rod to rotate more than 90°, stopping the rotation. At this point, the locking block is in contact with one side of the inner wall of the limiting groove, preventing the support rod from continuing to rotate, eliminating the need for manual adjustment of the pressure roller position.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and 8 A stop 510 is fixed to the end of the slide rod 58, and the diameter of the stop 510 is larger than that of the slide rod 58. The stop 510 can limit the support rod 9 and prevent the support rod 9 from detaching from the slide rod 58.

[0041] In practical operation, the present invention works as follows: First, the protrusion 48 is manually pushed, sliding against the inner wall of the transverse groove 49. As the protrusion 48 moves, it causes the stop rod 44, which is fixed to it, to move. The stop rod 44 slides against the inner wall of the slide groove 43. As the stop rod 44 moves, it compresses the spring 46, causing the stop rod 44 to disengage from the inner wall of the limiting hole 32. Then, the cabinet door 4 is opened, the protrusion 48 is released, and the spring 46 causes the stop rod 44 to return to its original position. Next, the wire spool is fitted onto the outside of the wire spool mounting rod, and then the wire spool is fixed by tightening bolts. Then, a suitable wire feeding wheel is selected according to the wire diameter. When replacing the wire feeding wheel 10, the support rod 9 is pulled outwards, sliding against the outer wall of the slide rod 58. When the support rod 9 and the stop rod 44 move together... When block 510 contacts, stop pulling the support rod 9, and then rotate the support rod 9. The support rod 9 rotates around the slide rod 58 as the center. The rotation of the support rod 9 will drive the compression ring 91 connected to it to rotate. When the compression ring 91 rotates, it will contact one side of the bottom of the mounting frame 6. The support rod 9 continues to rotate, and the mounting frame 6 will move upward. When the mounting frame 6 moves upward, the limiting plate 7 connected to it will also move upward. The guide rod 72 at the top of the limiting plate 7 moves upward on the inner wall of the vertical groove 82. At this time, the second gear and the third gear are separated. When the guide rod 72 moves to the top of the inner wall of the vertical groove 82, it will enter the inner wall of the inclined groove 83. The guide rod 72 slides on the inner wall of the inclined groove 83. Under the action of the inclined groove 83, the mounting frame 6 will move obliquely upward. When the support rod 9 rotates at an angle greater than 90 degrees, one side of the inner wall of the rotating groove 93 contacts one side of the clamping block 59. At this point, the rotation of the support rod 9 stops, and the downward gravity of the mounting bracket 6 will squeeze the compression ring 91 at the end of the support rod 9, preventing the support rod 9 from rotating. Then, the wire feeding wheel 10 is removed from the outer wall of the shaft 56. The support rod is no longer on the movement trajectory of the wire feeding wheel 10. The wire feeding wheel 10 corresponding to the welding wire is sleeved on the outer wall of the shaft 56, so that the wire feeding wheel 10 contacts the rubber pad 94 on one side of the blocking disc 511. The welding wire passes through the inside of the wire guide tube 51, passes through the ends of the two sets of wire feeding wheels 10, and enters the inside of the wire feeding tube 52, and then reverses. Rotate the support rod 9, and the support rod 9 will rotate and reset. When the support rod 9 rotates, the mounting bracket 6 will reset under its own gravity. The guide rod 72 will slide on the inner wall of the inclined groove. When the extrusion ring 91 is not in contact with the mounting bracket 6, the guide rod 72 will move from the inner wall of the inclined groove to the inner wall of the vertical groove 82. When the other side of the locking block 59 contacts the other side of the inner wall of the limiting groove 93, the support rod 9 will stop rotating. The second gear 57 will mesh with the third gear 66. At this time, the guide rod 72 is located at the bottom of the inner wall of the vertical groove 82, pushing the support rod 9. The support rod 9 will slide on the outer wall of the slide rail 58 until the rubber pad 94 on one side of the extrusion ring 91 contacts the wire feeding wheel 10. Next, the lead screw 71 is rotated. According to the lead screw principle, the rotation of the lead screw 71 will drive the mounting bracket 6 to move up and down. According to the diameter of the selected welding wire, the distance between the pressure roller 61 and the wire feeding roller 10 is adjusted. By observing the position between the fixed plate 65 and the scale line, the adjusted distance is ensured. Then, the protrusion frame 48 is pushed, and the stop rod 44 slides on the inner wall of the slide groove 43. When the first limiting block 41 on the cabinet door side contacts the extrusion block 76, the first limiting block 41 will extrude the extrusion block 76, thereby limiting the limiting plate 7. The second limiting block 42 will extrude the support rod 9, the support rod 9 will extrude the extrusion ring 91, and the extrusion ring 91 will extrude the wire feeding roller 10, thereby increasing the friction between the wire feeding roller 10 and the two sets of rubber pads. Then, the protrusion 48 is released, and the spring 46 drives the stop rod 44 to reset. The stop rod 44 enters the inner wall of the limiting hole 32.
