Description

Technical Field

[0001] This utility model relates to the field of polishing roller alternation switching technology, and in particular to a polishing roller alternation switching device. Background Technology

[0002] Polishing rollers are the core components of polishing equipment. They are usually composed of rollers, polishing ribs, and air jets. They come in various shapes, such as cylindrical, conical, or polygonal cylinders. They achieve the effects of deburring, polishing, or improving the smoothness by rotating at high speed and rubbing against the surface of the workpiece. Because continuous operation for a long time can lead to uneven wear or blockage of the roller surface, alternating operation can extend the service life of the equipment and ensure continuous production.

[0003] Traditional polishing rollers are mounted on large grinding machines or lathes for grinding and polishing. During operation, appropriate polishing materials are selected according to the surface condition of the workpiece, and the speed and pressure of the polishing rollers are controlled to achieve the polishing effect.

[0004] The traditional polishing roller switching process is limited by the complexity of the mechanical structure, resulting in cumbersome and time-consuming switching steps. In addition, the polishing roller replacement process relies on manual intervention, which is time-consuming and labor-intensive, and frequent machine shutdowns for replacement cause problems affecting production continuity. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a polishing roller alternation switching device, which aims to improve the problem that the alternation switching process of traditional polishing rollers in polishing operations is limited by the complexity of the mechanical structure, resulting in cumbersome switching steps and long time consumption.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a polishing roller alternation switching device, comprising a polishing table, on both sides of the upper surface of the polishing table being fixedly connected to guide rails, a rotating shaft base being slidably connected inside the guide rails, a connecting plate being fixedly connected to the outer wall of the rotating shaft base, a housing being slidably connected to the outer wall of the connecting plate, and a switching component being provided inside the housing;

[0007] The switching assembly includes rack one and rack two. The outer walls of rack one and rack two are slidably connected to the inside of the housing. Motor one is fixedly connected to the outer wall of the housing. A rotating shaft three is fixedly connected to the output end of motor one. A gear is fixedly connected to the outer wall of rotating shaft three. Slide rails are slidably connected to the outer walls of rack one and rack two.

[0008] Furthermore, a second motor is fixedly connected to the outer wall of the rotating shaft base, a first rotating shaft is fixedly connected to the output end of the second motor, a positioning block is fixedly connected to one end of the first rotating shaft, a second rotating shaft is slidably connected to the outer wall of the positioning block, a roller is provided on the outer wall of the second rotating shaft, a rotating column is fixedly connected to the outer wall of the first rotating shaft, a fixing plate is fixedly connected to the outer wall of the rotating column, a locking block is fixedly connected to the outer wall of the fixing plate, a bolt is rotatably connected inside the fixing plate, and a limit block is fixedly connected to one end of the bolt.

[0009] Furthermore, the outer wall of the connecting plate is slidably connected to the inside of the guide rail, and the outer shell is fixedly connected to the upper surface of the polishing table.

[0010] Furthermore, rack one and rack two are respectively meshed on both sides of the outer wall of the gear.

[0011] Furthermore, the outer wall of the slide rail is fixedly connected to the inner wall of the housing, and the outer walls of both rack one and rack two are fixedly connected to one end of the connecting plate.

[0012] Furthermore, the outer wall of the card block is slidably connected to the inside of the second rotating shaft, and the bolt is threadedly connected to the inside of the first rotating shaft.

[0013] Furthermore, the outer wall of the rotating shaft is rotatably connected to the inside of the rotating shaft base, and the roller body is positioned above the polishing table.

[0014] Furthermore, the fixed plate is provided with a sliding groove inside, and the outer wall of the limiting block is slidably connected to the inside of the fixed plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the rotating shaft three is driven by motor one to rotate the gear. Through the meshing transmission of the gear with rack one and rack two, the rack moves synchronously in the opposite direction along the slide rail. This is converted into horizontal reciprocating movement of the rotating shaft base on both sides on the guide rail by the connecting plate. This solves the problem that the traditional polishing roller switching process is limited by the complexity of the mechanical structure, resulting in complicated switching steps and long time consumption. It achieves the effect of rapid switching of polishing rollers.

[0017] 2. In this utility model, by rotating the bolts on the fixing plate, the constraint on the locking block is released by the radial contraction of the limiting block, allowing the locking block to disengage from the second rotating shaft. Then, the second rotating shaft and the roller body are pulled away along the axial direction of the positioning block. After replacing the new roller body, the bolts are tightened in the reverse direction. The limiting block is used to push the locking block to re-embed into the second rotating shaft to complete the quick fixation. This solves the problem that the traditional polishing roller replacement process relies on manual intervention, which is time-consuming and labor-intensive, and the frequent machine stoppages caused by the replacement affect the continuity of production. It achieves the effect of quick replacement of polishing rollers. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 5 The present invention provides an embodiment of a polishing roller alternation switching device, comprising a polishing table 1, which serves as the basic platform for the entire device to ensure the stability of the polishing operation. Guide rails 2 are fixedly connected to both sides of the upper surface of the polishing table 1. A rotating shaft base 3 is slidably connected inside the guide rails 2. A connecting plate 10 is fixedly connected to the outer wall of the rotating shaft base 3. The connecting plate 10 is used to connect the rotating shaft base 3 with rack 14 and rack 2 16. A housing 8 is slidably connected to the outer wall of the connecting plate 10. A switching component is provided inside the housing 8.

[0027] The switching assembly includes rack one 14 and rack two 16. Rack one 14 and rack two 16 are driven by gear 15 to achieve synchronous linear motion in opposite directions. The outer walls of rack one 14 and rack two 16 are slidably connected to the inside of housing 8. Motor one 9 is fixedly connected to the outer wall of housing 8. A rotating shaft three 13 is fixedly connected to the output end of motor one 9. Gear 15 is fixedly connected to the outer wall of rotating shaft three 13. Gear 15 meshes with rack one 14 and rack two 16, converting the rotational motion of motor one 9 into linear motion. Slide rails 21 are slidably connected to the outer walls of rack one 14 and rack two 16. Motor two 12 is fixedly connected to the outer wall of rotating shaft base 3. Motor 12 drives the rotating shaft 4 to rotate, which in turn drives the roller 7 to polish the surface of the workpiece. The output end of motor 12 is fixedly connected to the rotating shaft 4. One end of the rotating shaft 4 is fixedly connected to the positioning block 17. The positioning block 17 ensures the coaxiality of the rotating shaft 4 and the rotating shaft 5, and realizes efficient power transmission. The rotating shaft 5 is slidably connected to the outer wall of the positioning block 17. The roller 7 is set on the outer wall of the rotating shaft 5. The rotating column 6 is fixedly connected to the outer wall of the rotating shaft 4. The fixing plate 11 is fixedly connected to the outer wall of the rotating column 6. The locking block 18 is fixedly connected to the outer wall of the fixing plate 11. The bolt 19 is rotatably connected inside the fixing plate 11. One end of the bolt 19 is fixedly connected to the limit block 20.

[0028] Reference Figure 1 - Figure 5 The outer wall of the connecting plate 10 is slidably connected to the inside of the guide rail 2. The outer shell 8 is fixedly connected to the upper surface of the polishing table 1. The first rack 14 and the second rack 16 are respectively meshed on both sides of the outer wall of the gear 15. The outer wall of the slide rail 21 is fixedly connected to the inner wall of the outer shell 8. The slide rail 21 restricts the movement direction of the first rack 14 and the second rack 16, so that they slide in a straight line, thereby improving the transmission accuracy and stability. The outer walls of the first rack 14 and the second rack 16 are both fixedly connected to one end of the connecting plate 10. The outer wall of the locking block 18 is slidably connected to the inside of the second rotating shaft 5. The locking block 18 is embedded in the inside of the second rotating shaft 5 to achieve axial fixation. The bolt 19 is threadedly connected to the inside of the first rotating shaft 4. The bolt 19 drives the limiting block 20 to move radially by rotation, thereby controlling the axial position of the locking block 18 and realizing the quick loading and unloading of the second rotating shaft 5. The outer wall of the first rotating shaft 4 is rotatably connected to the inside of the rotating shaft base 3. The roller 7 is set above the polishing table 1. The inside of the fixing plate 11 is provided with a sliding groove. The outer wall of the limiting block 20 is slidably connected to the inside of the fixing plate 11.

[0029] Working principle: When alternating polishing with polishing rollers is required, motor 9 is started first, and shaft 13 drives gear 15 to rotate. Gear 15 simultaneously meshes with racks 14 and 16, causing racks 14 and 16 to move synchronously in opposite directions along slide rail 21. This is converted into horizontal reciprocating motion of the two rotating shaft bases 3 on guide rail 2 via connecting plate 10. When the left roller 7 moves into the processing position with the rotating shaft base 3, the right roller 7 simultaneously retracts to the standby position. During the polishing operation, motor 12 built into the rotating shaft base 3 drives shaft 4 to rotate at high speed, which is controlled by positioning block 1. The roller 7, in conjunction with the shaft hole of the second rotating shaft 5, transmits torque, driving the roller 7 to grind the workpiece surface at a preset speed. In addition, when the polishing roller needs to be replaced, the operator rotates the bolt 19 on the rotating fixing plate 11, and the outer wall limiting block 20 retracts radially along the slide groove of the fixing plate 11, releasing the axial constraint on the locking block 18, so that the locking block 18 can be dislodged from the inside of the second rotating shaft 5. At this time, the second rotating shaft 5 and the roller 7 can be axially pulled away along the positioning block 17. After replacing the new roller 7, the bolt 19 is operated in the opposite direction, and the locking block 18 is pushed back into the second rotating shaft 5 through the limiting block 20 to achieve quick fixation and complete the replacement of the polishing roller.
