Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] The present utility model provides a technical solution: As Figures 1 to 4 shown, in this embodiment, a polishing device for processing guide blocks includes a workbench 1. A rotating table 2 is rotatably installed in the middle of the workbench 1. An outer ring of the rotating table 2 is provided with storage grooves 3 for storing guide blocks in an annular array centered on the central axis of the rotating table 2. A sliding seat 4 is slidably installed on the outer ring of the workbench 1. A polishing wheel 5 for polishing and grinding the middle part of the guide block is installed on the top of the sliding seat 4. A conveyor belt 6 is installed at the bottom of the workbench 1. A pushing rod 7 for extruding the guide block is installed at a position of the rotating table 2 corresponding to the conveyor belt 6. The pushing rod 7 slides intermittently as the rotating table 2 rotates, and the guide blocks are sequentially placed in the storage grooves 3 of the rotating table 2. By controlling the rotation of the rotating table 2, the guide blocks are sequentially conveyed to the polishing wheel 5. By controlling the rotation of the polishing wheel 5, the middle groove of the guide block is polished and ground. The operation is simple. After polishing, as the rotating table 2 rotates, the guide block will be conveyed to the pushing rod 7. By the extrusion of the pushing rod 7 on the guide block, the guide block is pushed onto the conveyor belt 6 for intermittent blanking of the guide block.

[0022] As Figures 1 to 4 shown, a feeding motor 8 is fixedly installed on the lower surface of the top of the rotating table 2. The output end of the feeding motor 8 passes through the rotating table 2 and is fixedly connected to the rotating table 2. A polishing motor 9 is fixedly installed at the bottom of the sliding seat 4. The output end of the polishing motor 9 passes through the sliding seat 4 and is fixedly connected to the polishing wheel 5.

[0023] By controlling the rotation of the rotating table 2 by the feeding motor 8, the guide blocks are sequentially conveyed to the polishing wheel 5, and by controlling the rotation of the polishing wheel 5 by the polishing motor 9, polishing and grinding of the guide blocks are realized.

[0024] As Figures 1 to 4 shown, positioning plates 10 are fixedly installed on both sides of the upper surface of the rotating table 2 corresponding to the position of the polishing wheel 5, and the positioning plates 10 are arranged at the outer ring position of the rotating table 2.

[0025] It is used to squeeze and position the placed guide blocks, and stably convey the guide blocks to the polishing wheel 5.

[0026] As Figures 1 to 4 shown, limiting rods 11 are symmetrically and fixedly installed inside the rotating table 2 corresponding to the position of the sliding seat 4. Limiting holes 12 are opened at the positions of the sliding seat 4 corresponding to the limiting rods 11. The limiting holes 12 are slidably connected with the limiting rods 11. An extrusion spring 13 is sleeved on the outer side of the limiting rod 11. One end of the extrusion spring 13 is fixedly connected with the sliding seat 4, and the other end of the extrusion spring 13 is fixedly connected with the rotating table 2.

[0027] During the conveying of the guide blocks and the polishing of the guide blocks, the polishing wheel 5 will first contact the groove at one end of the guide block. As the guide block is conveyed, the guide block will squeeze the polishing wheel 5, driving the sliding seat 4 equipped with the polishing wheel 5 to slide along the limiting rod 11 for fitting the overall groove of the guide block.

[0028] As Figures 1 to 4 shown, positioning rods 14 are symmetrically and fixedly installed inside the rotating table 2 corresponding to the position of the conveyor belt 6. A moving block 15 is slidably installed between the two positioning rods 14. A return spring 16 is sleeved on the outer side of the positioning rod 14. One end of the return spring 16 is fixedly connected with the moving block 15, and the other end of the return spring 16 is fixedly connected with the rotating table 2. A guide rod 17 is fixedly installed on the top of the moving block 15. A guide groove 18 is opened on the lower surface of the rotating table 2 corresponding to the position of the guide rod 17. The guide groove 18 includes a vertical section, an inclined section and a circumferential section. The guide groove 18 is slidably connected with the guide rod 17. The pushing rod 7 is fixedly installed on the outer side of the guide rod 17.

[0029] During the rotation of the rotating table 2, the guide rod 17 continuously slides inside the guide groove 18. Before the guide block is conveyed to the position of the pushing rod 7, the guide rod 17 continuously slides inside the circumferential section of the guide groove 18. As the rotating table 2 rotates, when the guide block is conveyed to be directly opposite the pushing rod 7, the return spring 16 pushes the moving block 15, causing the guide rod 17 to instantaneously slide inside the vertical section of the guide groove 18. The pushing rod 7 installed on the guide rod 17 will instantaneously squeeze the guide block and push the guide block onto the conveyor belt 6 for discharging the guide block. As the rotating table 2 rotates, the inclined section of the guide groove 18 will squeeze the guide rod 17 to drive the moving block 15 connected to the guide rod 17 to slide along the two positioning rods 14. At this time, the return spring 16 is in a compressed state. In this way, intermittent discharging of the guide blocks is realized.

[0030] As shown Figures 1 to 4 As shown, a triangular groove 19 is formed at one end of the guide rod 17 away from the pusher rod 7.

[0031] It is used to extrude the top angle of the guide block.

[0032] As shown Figures 1 to 4 As shown, a protective plate 20 is installed at the top of the workbench 1 corresponding to the rotation track of the guide block.

[0033] It is used to prevent wear between the guide block and the workbench 1 during transportation.

[0034] The present utility model provides a polishing device for processing guide blocks, and the specific working principle is as follows:

[0035] When the device is in use, the guide blocks are sequentially placed inside the receiving grooves 3 of the rotating table 2. The rotating table 2 is controlled by the feeding motor 8 to rotate, so as to sequentially convey the guide blocks to the polishing wheel 5. The polishing wheel 5 is controlled by the polishing motor 9 to rotate, which is used to polish and grind the middle groove of the guide block. During the transportation of the guide block and the polishing of the guide block, the polishing wheel 5 will first contact the groove at one end of the guide block. As the guide block is conveyed, the guide block will extrude the polishing wheel 5, driving the sliding seat 4 installed with the polishing wheel 5 to slide along the limiting rod 11, so as to fit the overall groove of the guide block and realize the overall grinding of the groove of the guide block;

[0036] During the rotation of the rotating table 2, the guide rod 17 continuously slides inside the guide groove 18. Before the guide block is conveyed to the position of the pusher rod 7, the guide rod 17 continuously slides inside the circumferential section of the guide groove 18. As the rotating table 2 rotates, when the guide block is conveyed to be directly opposite the pusher rod 7, the guide rod 17 instantaneously slides inside the vertical section of the guide groove 18 by the pushing of the return spring 16 on the moving block 15. The pusher rod 7 installed with the guide rod 17 will instantaneously extrude the guide block, pushing the guide block onto the conveyor belt 6 for discharging the guide block. As the rotating table 2 rotates, the inclined section of the guide groove 18 will extrude the guide rod 17, driving the moving block 15 connected to the guide rod 17 to slide along the two positioning rods 14. At this time, the return spring 16 is in a compressed state, and so on, realizing the intermittent discharging of the guide block.
