Detailed Embodiments

[0017] The following further elaborates on the present utility model in detail in conjunction with the drawings of the specification and the specific embodiments.

[0018] Refer to Attachments Figure 1 to Attachment Figure 4As shown, this embodiment provides a soft polishing tool setting device, which includes a worm gear box 1, a worm gear transmission assembly, a main shaft sleeve 2, a main motor 9, a main shaft 3, a grinding wheel 6, a cylinder 16, an adjusting rod 12, a main board 8, a first detection plate 14, a second detection plate 13 and a proximity switch 15.

[0019] The main shaft sleeve 2 is slidably mounted on the worm gear box 1, that is, the main shaft sleeve 2 can reciprocate along its axial direction relative to the worm gear box 1. The main shaft 3 is installed in the inner cavity of the main shaft sleeve 2, and the main shaft 3 is rotatably connected with the inner cavity of the main shaft sleeve 2 through bearings 4 installed at both ends. The grinding wheel 6 is fixedly mounted on the head of the main shaft 3, and the tail of the main shaft 3 is connected to the main motor 9 by means of a coupling 7. The main motor 9 is connected to the tail of the main shaft 3 by means of the coupling 7, and the main motor 9 drives the main shaft 3 to rotate the grinding wheel 6, thereby providing the cutting ability of the grinding wheel 6. In order to ensure the installation sealing at the head of the main shaft 3, a sealing ring 5 is also installed at the head of the main shaft 3.

[0020] The main board 8 is fixed to the main shaft sleeve 2 at its front side by screws, and the back side of the main board 8 is fixedly connected to the main motor 9 , the cylinder 16 and the first detection plate 14 . The proximity switch 15 is fixedly mounted on the first detection plate 14 .

[0021] The shoulder of the adjusting rod 12 is connected to the main board 8, and the head of the adjusting rod 12 protrudes 3mm from the main board to form a clearance fit. The other end of the adjusting rod 12 is connected to the worm gear transmission assembly so that the adjusting rod 12 can move back and forth in a straight line. The second detection plate 13 is fixedly installed on the head of the adjusting rod 12, and a 1.5mm gap is left between the second detection plate 13 and the proximity switch 15.

[0022] The worm gear transmission assembly includes a servo motor 24, a worm 18, a worm wheel 17, an active synchronous wheel 23, a passive synchronous wheel 21 and a synchronous belt 22. The servo motor 24 is connected to the active synchronous wheel 23, and the active synchronous wheel 23 is connected to the passive synchronous wheel 21 through the synchronous belt 22. The passive synchronous wheel 21 is fixedly mounted on one end of the worm 18, and bearings 19 are installed at both ends of the worm 18. The worm 18 is meshed with the worm wheel 17, and the worm wheel 17 is meshed with one end of the adjustment rod 12 (the worm wheel 17 is internally processed with threads to perform spiral transmission with the adjustment rod 12, so that the rotation of the worm wheel 17 drives the adjustment rod 12 to perform linear motion), which is used to drive the adjustment rod 12 to move back and forth in a straight line. The servo motor 24 is fixedly mounted on the worm gear box 1 through the servo motor plate 20 provided.

[0023] The cylinder 16 is fixedly mounted on the main board 8, and the piston rod of the cylinder 16 is connected to the worm gear box 1 through the end cover 11 provided. The stopper 10 is placed in front of the grinding wheel 6, and the stopper 10 is stationary.

[0024] When the servo motor 24 rotates, the worm gear 17 drives the adjusting rod 12 to make the main board 8, the main shaft sleeve 2, the main shaft 3, and the grinding wheel 6 move linearly. When processing glass, the air cylinder 16 is always ventilated and contracted, and the air pressure is lower than the reaction force when grinding the glass. Because there is a gap between the head of the adjusting rod 12 and the main board 8, if the instantaneous load of the grinding wheel 6 is large, the strong reaction force causes the grinding wheel 6 to drive the main shaft 3 and the main board 8 to move backward until the normal polishing force is reached. There is no need to control a series of complex operations such as the servo motor 24 adjusting the carriage forward and backward through the current feedback of the main motor 9, which can well protect the main motor 9 from being easily overloaded and having poor polishing. When the grinding wheel 6 needs to be tooled, the proximity switch 15 always senses that the second detection board 13 is always lit. The air cylinder 16 is always ventilated and contracted, and the pressure is greater than the frictional force of the adjusting rod 12. The servo motor 24 rotates the worm 18, and the worm gear 17 and the adjusting rod 12 perform a spiral drive. The adjusting rod 12 pulls the main board 8, the main shaft sleeve 2, the main shaft 3, and the grinding head to move forward all the time. When the grinding wheel 6 touches the front stop block 10, the main board 8 can no longer move forward. Since there is a gap between the head of the adjusting rod 12 and the main board 8, the worm 18, the worm gear 17, the synchronous pulley, and the servo motor 24 can still rotate. When the second detection board 13 leaves the proximity switch 15, the proximity switch 15 turns off, and it is judged that the tooling is successful. The servo motor 24 immediately reverses to control the grinding wheel 6 to return to the grinding edge position.

[0025] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model is also intended to include these changes and modifications.
