Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, and in particular to a multi-station adjustable speed polishing machine. Background Technology

[0002] Multi-station adjustable speed polishing machines are specialized equipment used in the industrial field for workpiece surface treatment. Their core features are reflected in two dimensions: "multi-station" and "adjustable speed". This equipment is widely used in hardware manufacturing, automotive parts processing, and daily necessities production. Its core function is to remove surface defects of workpieces through the friction between the polishing wheel and the workpiece.

[0003] Currently, most multi-station polishing machines on the market have a rotary turntable structure. In terms of power control, they mostly use variable frequency motors with reducers to achieve stepless speed regulation of the polishing spindle, adapting to the speed requirements of different processes such as rough polishing, fine polishing, and mirror polishing. In terms of station layout, the rotary turntable type uses intermittent rotation to sequentially send workpieces to different polishing stations.

[0004] However, existing multi-station polishing machines still have significant technical shortcomings in practical applications: when processing the same batch of parts, clamping requires individual clamping, reducing overall production efficiency; and due to the repetitiveness and uncertainty of manual operation, it is difficult to ensure that the clamping state of each workpiece is completely consistent, posing a potential risk to the quality of subsequent processing. Furthermore, the polishing heads of existing equipment are mostly connected to the machine frame via rigid supports, making it impossible to adaptively adjust according to the actual contour or minor surface undulations of the workpiece. Therefore, it is necessary to develop a multi-station adjustable-speed polishing machine to address the pain points of existing technologies. Utility Model Content

[0020] Reference Figure 1-4 This utility model provides an embodiment of a multi-station adjustable speed polishing machine, comprising a base 1, a linear module 2 fixedly connected to one side of the top of the base 1, the linear module 2 being a ball screw type module capable of driving a slider to move up and down, a rotating platform 4 rotatably connected to the other side of the top of the base 1, a connecting platform 5 fixedly connected to the middle of the top of the rotating platform 4, a gear ring 6 rotatably connected to the middle of the bottom of the connecting platform 5, connecting columns 10 penetrating and rotatably connected to all four sides of the top of the connecting platform 5, gears 7 fixedly connected to the bottom of each connecting column 10, the gears 7 meshing with the gear ring 6, and a first motor 8 fixedly connected to one side of the top of the rotating platform 4, the output end of the first motor 8 being connected to the right... The bottom of the side gear 7 is fixedly connected. The first motor 8 starts and drives the gear 7 to rotate synchronously. The bottom of the base 1 is fixedly connected to the second motor 9. The output end of the second motor 9 is fixedly connected to the rotating platform 4. The second motor 9 can drive the rotating platform 4 to rotate when it starts. The top of the connecting column 10 is fixedly connected to the fixing plate 14. The gear 7 can drive the fixing plate 14 to rotate when it rotates. The top four sides of the fixing plate 14 are provided with guide grooves 15. The outer ring of the connecting column 10 is rotatably connected to the rotating sleeve 11. The bottom of the rotating sleeve 11 is fixedly connected to the connecting platform 5. The four sides of the outer ring of the rotating sleeve 11 are provided with clamping components. The top two sides of the slider of the linear module 2 are provided with buffer components.

[0021] The clamping assembly includes a limiting post 12, one end of which is fixedly connected to a rotating sleeve 11. A sliding block 13 is slidably connected through the outer ring of the rotating sleeve 11. A clamping block 16 is fixedly connected to the top of each sliding block 13. Rotation of the fixing plate 14 can drive the clamping block 16 to move along the limiting post 12. Guided by the guide groove 15, the clamping block 16 can clamp and release simultaneously, allowing for the simultaneous clamping and limiting of four identical parts. The buffer assembly includes a support frame 17, the bottom of which is fixedly connected to the slider of the linear module 2. A sliding groove 21 is provided at one end of one side of the left support frame 17, and a sliding groove 21 is provided at the other end of the other side of the right support frame 17. A threaded rod 20 is rotatably connected through the top of each support frame 17. A nut pair 27 is threadedly connected through the outer ring of each threaded rod 20. Both ends of the nut pair 27 are slidably connected to the sliding groove 21. A sliding plate 19 is fixedly connected between the nut pairs 27. The two threaded rods 20 rotate synchronously, which can drive... The sliding plate 19 moves, and springs 24 are fixedly connected to the four corners of the bottom of the sliding plate 19. A connecting plate 18 is fixedly connected to one end of each spring 24. The sliding plate 19 moves up and down, squeezing or releasing the springs 24 to change the elastic force of the springs 24 and change the buffering force on the polishing components. Appropriate buffering force is matched for workpieces of different hardness. The two sides of the connecting plate 18 are slidably connected to the support frame 17. The top of the threaded rod 20 is fixedly connected to the synchronous pulley 22. The outer ring of the synchronous pulley 22 is fitted with a synchronous belt 23. The top of the right synchronous pulley 22 is fixedly connected to the rotating rod 25. Rotating the rotating rod 25 drives the two synchronous pulleys 22 to rotate synchronously, which drives the threaded rod 20 to rotate. The bottom of the connecting plate 18 is fixedly connected to the polishing machine body 3. The polishing machine body 3 can be speed-adjusted through a three-phase asynchronous motor and a frequency converter. A polishing wheel 26 is set at the output end of the polishing machine body 3, and the output end of the polishing machine body 3 passes through and slides through the slider of the linear module 2 without affecting the buffering of the spring 24.

[0022] Working principle: The second motor 9 starts, driving the rotating table 4 to rotate, which in turn causes the connecting table 5 and the components above it to rotate synchronously, realizing the switching of work positions. The first motor 8 starts, driving the right gear 7 to rotate. Gear 7 meshes with the gear ring 6, causing all gears 7 to rotate synchronously. The rotation of gear 7 drives the connecting column 10 to rotate, and the fixing plate 14 on the top of the connecting column 10 also rotates accordingly. When the fixing plate 14 rotates, it drives the clamping block 16 to move along the limiting column 12. At the same time, with the guidance of the guide groove 15, the clamping block 16 can complete the clamping and releasing action of the workpiece. Rotating the rotating rod 25 drives the right synchronous pulley 22 to rotate. Through the synchronous belt 23, the left synchronous pulley 22 rotates synchronously. The synchronous pulley 22 drives the threaded rod 20 to rotate. When the two threaded rods 20 rotate synchronously, they drive the nut pair 27 and the connected sliding plate 19 to move up and down along the sliding groove 21. When the sliding plate 19 moves, it compresses or relaxes the springs 24 at the four corners at the bottom, thereby changing the elastic force of the springs 24 and achieving precise adjustment of the buffering force of the polishing assembly. The linear module 2 is a ball screw type module, and its slider can drive the top fixed support frame 17 and the entire buffer assembly to move up and down, initially adjusting the relative position of the polishing wheel 26 and the workpiece. The sliding plate 19 is connected to the connecting plate 18 through the springs 24. The bottom of the connecting plate 18 is fixed to the polishing machine body 3, which in turn drives the polishing wheel 26 to move closer to and away from the workpiece. The polishing machine body 3 achieves speed regulation through a three-phase asynchronous motor and frequency converter. Its output end is connected to the slider of the linear module 2 through and slides, ensuring that there is no movement interference when the springs 24 buffer. When the polishing wheel 26 contacts the workpiece, the springs 24 deform according to the preset elastic force, offsetting the polishing impact force and achieving stable polishing.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
