Description

Technical Field

[0001] This invention belongs to the technical field of metal rod surface processing equipment, and particularly relates to a grinding machine for processing non-ferrous metal alloy rods. Background Technology

[0002] Non-ferrous metal alloy bars are fundamental materials widely used in aerospace, automotive manufacturing, electronics, and precision machinery. Their surface quality directly affects the accuracy of subsequent processing and the performance of the finished product. Therefore, before the bars leave the factory or are processed, their surfaces usually need to be polished to remove oxide scale, burrs, and surface defects.

[0003] The common grinding method involves the operator holding the alloy rod and placing its surface against a rotating grinding belt for manual grinding. However, this method requires a high degree of manual intervention, is labor-intensive, and poses significant safety hazards. Furthermore, grinding each rod individually results in extremely low production efficiency, which cannot meet the needs of mass production. In addition, uneven application of force can easily lead to inconsistent surface roughness of the products, resulting in a high scrap rate.

[0004] Therefore, there is a particular need for a non-ferrous metal alloy bar processing and grinding machine to solve the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of common manual grinding methods, such as excessive human intervention, high labor intensity, high safety hazards, low efficiency of grinding one bar at a time, and uneven force application that easily leads to poor surface roughness consistency and high scrap rate, this invention provides a grinding machine for processing non-ferrous metal alloy bars.

[0006] This invention is achieved through the following technical means: a non-ferrous metal alloy bar processing and grinding machine, comprising a support, a controller, a first motor, a first transmission roller, a first grinding belt, a moving frame, rollers, a worm gear, a worm, a second motor, a second transmission roller, and a second grinding belt; the controller and the first motor are fixedly installed on the outer wall of the support; two first transmission rollers are rotatably connected to the upper part of the support in the horizontal direction; the output shaft of the first motor is fixedly connected to one of the first transmission rollers; a first grinding belt is wound between the two first transmission rollers; and a moving frame is slidably connected to the upper part of the support. Rollers are rotatably connected to both sides of the movable frame. Each roller has a worm gear coaxially fixed to its end that passes through the movable frame. Two worms are rotatably connected inside the movable frame, and the worms mesh with the worm gears on the same side. A second motor is fixedly installed inside the movable frame. Both the first and second motors are electrically connected to a controller. The output shaft of the second motor is fixedly connected to one of the worms. Two transmission rollers are rotatably connected inside the movable frame, and the transmission rollers are fixedly connected to the worms on the same side. A grinding belt is wound between the two transmission rollers.

[0007] To further explain, the upper part of the bracket has multiple spaced placement stations.

[0008] To further clarify, both motor one and motor two are geared motors.

[0009] To further clarify, the roller is a rubber roller.

[0010] To further explain, the lower surface of the second grinding belt is exposed through the lower opening of the moving frame.

[0011] To further explain, it also includes a mounting frame, a cylinder, and a limiting bracket. The mounting frame is fixedly mounted on the upper part of the bracket, and the cylinder is fixedly mounted on the top of the mounting frame. The piston rod of the cylinder passes downward through the mounting frame, and the limiting bracket is fixedly mounted on the end of the piston rod.

[0012] To further explain, the left side of the limiting frame is provided with a baffle structure for resisting the alloy rod.

[0013] Further explanation: It also includes a lifting frame, a rotating rod, a limiting roller, and a torsion spring. The lifting frame is slidably connected to one side of the limiting frame. A row of rotating rods is equidistantly rotatably connected to the upper part of the support. Two rows of limiting rollers are rotatably connected to each rotating rod. Adjacent limiting rollers on the same rotating rod are horizontally distributed and inserted into the placement position of the support. A torsion spring is sleeved on one end of each rotating rod. The two ends of the torsion spring are respectively connected to the support and the rotating rod.

[0014] To further explain, it also includes a movable plate and a screw. The movable plate is slidably connected to the upper part of the bracket, and the screw is rotatably connected to one side of the upper part of the bracket. The screw passes horizontally through the movable plate and forms a threaded engagement with the movable plate.

[0015] The beneficial effects of this invention are as follows: 1. By setting multiple placement stations on the upper part of the support, multiple alloy bars can be placed simultaneously for grinding. With the cooperation of motor one, transmission roller one and grinding belt one, multiple bars are initially ground synchronously. Then, through the moving frame, roller, worm gear, worm, motor two, transmission roller two and grinding belt two, automatic movement and deep grinding are achieved, realizing the simultaneous automated grinding of multiple bars, greatly improving grinding efficiency and reducing manual labor intensity.

[0016] 2. The left end of the alloy bar is limited by a cylinder and a limit bracket, and the right end of the alloy bar is positioned by a moving plate and a screw. This achieves uniform position calibration of multiple bars, ensuring stable bar position during grinding and improving grinding accuracy and consistency.

[0017] 3. By using the lifting frame, rotating rod, limiting roller and torsion spring in combination, the alloy bar is radially limited during the grinding process to prevent the bar from jumping during grinding and further ensure the grinding quality. Attached Figure Description

[0029] Example: A grinding machine for processing non-ferrous metal alloy bars, such as Figures 1-10As shown, the system includes a support frame 1, a controller 2, a motor 3, a transmission roller 4, a grinding belt 41, a moving frame 13, rollers 14, a worm gear 15, a worm 16, a second motor 17, a second transmission roller 18, and a second grinding belt 19. The upper part of the support frame 1 has multiple spaced placement positions. The controller 2 and motor 3 are bolted to the outer wall of the support frame 1. Two transmission rollers 4 are rotatably connected to the upper part of the support frame 1 in the horizontal direction. The output shaft of motor 3 is fixedly connected to the right transmission roller 4. A grinding belt 41 is wound between the two transmission rollers 4. The moving frame 13 is slidably connected to the upper part of the support frame 1. Rollers 14, made of rubber, are rotatably connected to both the front and rear sides of the moving frame 13 to increase rolling stability. Each roller 14 passes through the moving frame 13. A worm gear 15 is coaxially fixedly connected to the end of the moving frame 13. Two worms 16 are rotatably connected inside the moving frame 13. The worms 16 mesh with the worm gear 15 on the same side. A second motor 17 is fixedly installed inside the moving frame 13 by bolts. Both the first motor 3 and the second motor 17 are electrically connected to the controller 2. Both the first motor 3 and the second motor 17 are geared motors. The output shaft of the second motor 17 is fixedly connected to the rear worm 16 through a coupling. Two transmission rollers 18 are rotatably connected inside the moving frame 13. The transmission rollers 18 are fixedly connected to the worm 16 on the same side. A grinding belt 19 is wound between the two transmission rollers 18. The lower surface of the grinding belt 19 is exposed through the lower opening of the moving frame 13, so that the grinding belt 19 can continuously contact the alloy rod during the movement of the moving frame 13.

[0030] like Figures 1-3 and Figures 6-8 As shown, it also includes a mounting frame 5, a cylinder 6 and a limiting frame 7. The mounting frame 5 is fixedly installed on the upper part of the bracket 1 by bolts. The cylinder 6 is fixedly installed on the top of the mounting frame 5 by bolts. The piston rod of the cylinder 6 passes downward through the mounting frame 5, and the end of the piston rod is fixedly installed with the limiting frame 7 by bolts. The left side of the limiting frame 7 is provided with a baffle structure for resisting the alloy rod.

[0031] like Figures 3-5 As shown, it also includes a lifting frame 8, a rotating rod 9, a limiting roller 91, and a torsion spring 10. The lifting frame 8 is slidably connected to the left side of the limiting frame 7. Friction damping is provided at the sliding connection between the lifting frame 8 and the limiting frame 7 to increase the friction force between the lifting frame 8 and the limiting frame 7. When the lifting frame 8 slides along the limiting frame 7, the lifting frame 8 can be fixed at the height of the limiting frame 7 by friction damping. A row of rotating rods 9 is equidistantly rotatably connected to the upper part of the bracket 1. Two rows of limiting rollers 91 are rotatably connected to each rotating rod 9. Adjacent limiting rollers 91 on the same rotating rod 9 are horizontally distributed and intervene in the placement position of the bracket 1. A torsion spring 10 is sleeved on the left end of each rotating rod 9. The left and right ends of the torsion spring 10 are connected to the bracket 1 and the rotating rod 9 respectively, thereby providing rotational torque for the rotating rod 9.

[0032] like Figures 6-8As shown, it also includes a movable plate 11 and a screw 12. The movable plate 11 is slidably connected to the upper part of the bracket 1, and the screw 12 is rotatably connected to the rear side of the upper part of the bracket 1. The screw 12 passes horizontally through the movable plate 11 and forms a threaded engagement with the movable plate 11.

[0033] Initially, the lifting frame 8 is in a low position pressing each rotating rod 9, and every two adjacent limiting rollers 91 are horizontally distributed and intervene in the placement position of the bracket 1, and the torsion spring 10 is in a stored state. When it is necessary to grind the alloy rods, first pull the lifting frame 8 upward to the high position to disengage from each rotating rod 9. The torsion spring 10 immediately returns to its original shape, causing the rotating rod 9 to rotate 90 degrees. At this time, every two adjacent limiting rollers 91 rotate to a vertical distribution, avoiding the placement position of the bracket 1. At this time, multiple alloy rods can be placed into multiple placement positions of the bracket 1 in sequence. When placing, the surface of the alloy rod is in contact with the surface of the grinding belt 41. After placement, rotate the screw 12 to drive the moving plate 11 to push the alloy rod to the left until the left end of the alloy rod contacts the baffle structure of the limiting frame 7, thereby achieving the positioning of the alloy rod. Then, press the lifting frame 8 down again, so that the rotating rod 9 drives every two adjacent limiting rollers 91 to re-enter the placement position of the bracket 1, thereby making the roller surface of the limiting roller 91 contact the surface of the alloy rod, preventing the alloy rod from jumping during the subsequent grinding process. Then, the controller 2 starts motor 3 and motor 17. Motor 3 drives the right transmission roller 4 to cooperate with the left transmission roller 4, which drives the grinding belt 41 to rotate. This causes the grinding belt 41 to continuously slide and contact the surface of the alloy bar, achieving preliminary grinding. At the same time, motor 17 drives the rear worm gear 16 to rotate. The rear worm gear 16 drives the rear worm wheel 15, which drives the rear roller 14 to rotate synchronously. The rear worm gear 16 also drives the rear transmission roller 18 to rotate, which, together with the front transmission roller 18, drives the grinding belt 19 to rotate. The front transmission roller 18 also drives the front worm gear 16 to rotate. Driven by the front worm gear 16, the front worm wheel 15 drives the front roller 14 to rotate together, causing the moving frame 13 to move automatically on the support 1. The grinding belt 19 performs deep grinding along the length of the alloy bar. After the moving frame 13 has moved to the leftmost position and completed the grinding, turn off motor 17. Then, rotate screw 12 in the opposite direction to drive moving plate 11 to reset to the right and disengage from the right end of the alloy bar. Then, pull up lifting frame 8 again to make rotating rod 9 drive limiting roller 91 to disengage from the surface of the alloy bar and stop limiting. Finally, start cylinder 6 and control the piston rod of cylinder 6 to retract, driving limiting frame 7 to move upward and release the limitation on the left end of the alloy bar. At this time, grinding belt 41 continues to run, conveying the alloy bar to the left to achieve unloading. After unloading is completed, turn off motor 3 and control the piston rod of cylinder 6 to extend, driving limiting frame 7 to reset downward.
