[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 5 The utility model discloses an automatic compensation system for a polishing wheel, comprising a base 1, on one side of the top of which two sets of linear rails 4 are arranged in a horizontal direction, the two sets of linear rails 4 are slidably connected to a slide 5, and the outer side wall of the base 1 is fixedly connected to a driving motor 6 for driving the slide 5 to move;

[0028] The polishing compensation component 2 is composed of an X-axis slide rail 21, an X-axis slider 22, a support table 23, a distance sensor 24 and an elastic component 25, wherein the distance sensor 24 and the X-axis slide rail 21 are both installed on the top of the slide table 5, the outer side wall of the X-axis slide rail 21 is slidably connected with the X-axis slider 22, the top of the X-axis slider 22 is fixedly connected with the support table 23, and the elastic component 25 is arranged between the support table 23 and the slide table 5;

[0029] The polishing device 3 is arranged on the top of the support platform 23 and is connected to the support platform 23 via a Y-axis translation system 7 .

[0030] In this embodiment, Figure 1 As shown, the workpiece is placed in the loading mechanism shown at A, and the workpiece is loaded through the loading mechanism. Then, the drive motor 6 is operated to make the lead screw push the slide 5 to move along the linear rail 4, so that the polishing device 3 approaches and processes the workpiece.

[0031] When the polishing device 3 is grinding the workpiece, the polishing wheel 34 will also be damaged during the grinding, which will cause the diameter of the polishing wheel 34 to gradually shrink when processing the workpiece, resulting in a gap between the polishing wheel 34 and the workpiece, affecting the polishing of the workpiece.

[0032] So observe Figure 2 and Figure 3 It can be found that a polishing compensation component 2 is arranged between the slide 5 and the polishing device 3. When the polishing device 3 contacts the workpiece, the polishing device 3 will be squeezed by the workpiece due to the interaction force, so that the support table 23 installed with the polishing device 3 moves along the X-axis slide rail 21 relative to the slide 5 in a direction away from the workpiece, and the support table 23 and the slide 5 are connected by an elastic component 25, so that when the support table 23 slides along the X-axis slide rail 21, the elastic component 25 will be stretched, so that the elastic component 25 applies a reverse force to the support table 23, so that the support table 23 squeezes the workpiece with the polishing device 3, thereby ensuring that the polishing device 3 can maintain stable contact with the workpiece, which is used to avoid the wear of the polishing wheel 34 of the polishing device 3 and affect the polishing effect of the workpiece.

[0033] As the diameter of the polishing wheel 34 gradually decreases, the support table 23 will gradually move along the X-axis slide rail 21 relative to the slide table 5 in a direction close to the workpiece under the pull of the elastic component 25, until the elastic potential energy of the elastic component 25 disappears and the support table 23 can no longer be pulled to move, resulting in the polishing wheel 34 being unable to ensure contact with the workpiece in subsequent use. Figure 3 It can be found that a distance sensor 24 is arranged on the top of the slide 5. When the support table 23 moves under the correction of the elastic component 25, the distance between the support table 23 and the distance sensor 24 will increase, so that the distance sensor 24 sends a signal to control the operation of the drive motor 6, so that the slide 5 moves synchronously, so that the distance between the support table 23 and the distance sensor 24 remains the same, so that the elastic component 25 keeps pulling the support table 23, thereby achieving the effect that the polishing device 3 can stably polish the workpiece.

[0034] In a further preferred embodiment of the present invention, Figure 3 As shown, the distance sensor 24 includes a sensor body 241, a positioning block 242 and a connecting seat 243. The positioning block 242 is fixedly connected to the slide 5. A sliding groove is provided on the top of the positioning block 242 and is slidably connected to the connecting seat 243. The outer wall of the connecting seat 243 on one side close to the driving motor 6 is fixedly connected to the sensor body 241.

[0035] In this embodiment, because the support platform 23 can move relative to the slide table 5, when the distance sensor 24 is too close to the support platform 23, the sliding of the support platform 23 may collide with the distance sensor 24, causing damage to the distance sensor 24. If the distance sensor 24 is too far away from the support platform 23, the sensitivity of the distance sensor 24 to the distance change of the support platform 23 will be affected. Therefore, the installation position of the distance sensor 24 needs to be adjusted according to the movement range of the support platform 23.

[0036] observe Figure 3 It can be found that the positioning block 242 and the connecting seat 243 can be used to control the horizontal movement of the sensor body 241, so that the position of the sensor body 241 can be adjusted in real time, making the distance between the sensor body 241 and the support platform 23 easier to adjust.

[0037] In a further preferred embodiment of the present invention, Figure 3As shown, the elastic component 25 includes a support platform bolt 251, a slide platform bolt 252 and a tension spring 253. The support platform bolt 251 is installed on the top of the support platform 23 on the side close to the drive motor 6, and the slide platform bolt 252 is installed on the bottom of the slide platform 5 on the side away from the drive motor 6. The support platform bolt 251 and the slide platform bolt 252 respectively penetrate the support platform 23 and the slide platform 5, and extend between the support platform 23 and the slide platform 5. A tension spring 253 is connected between the support platform bolt 251 and the slide platform bolt 252.

[0038] In this embodiment, a support table bolt 251 and a slide table bolt 252 are set, and a tension spring 253 is set between the two bolts, so that when the support table 23 moves relative to the slide table 5, the tension spring 253 will be stretched, and the tension spring 253 is used to apply tension to the support table 23, so as to ensure that the polishing device 3 installed on the top of the support table 23 always maintains contact with the workpiece.

[0039] Because when the support platform 23 stops moving due to the pressure of the workpiece, the slide 5 will continue to move, causing the support platform 23 and the slide 5 to move relative to each other. Therefore, in order to stretch the tension spring 253 when the support platform 23 and the slide 5 move relative to each other, the slide bolt 252 is installed on the side of the slide 5 away from the drive motor 6, and the support platform bolt 251 is installed on the top of the support platform 23 close to the drive motor 6. At this time, when the support platform 23 and the slide 5 move relative to each other, the distance between the two bolts will increase, thereby achieving the effect of stretching the tension spring 253.

[0040] In a further preferred embodiment of the present invention, Figure 4 As shown, a limit block 8 is also installed on the top of the slide 5, and a baffle 9 is fixedly connected to the outer wall of the support platform 23 close to the driving motor 6, and a screw 10 is threadedly connected to one side of the baffle 9, and a stop block 11 is fixedly connected to one end of the screw 10 close to the limit block 8.

[0041] In this embodiment, a limit block 8 is set on the top of the slide 5, a baffle 9 is set on the side of the support platform 23 close to the drive motor 6, and at the same time, a stop block 11 is connected to one side of the baffle 9 through a screw 10. When the support platform 23 is reset under the pull of the tension spring 253, the stop block 11 is in contact with the limit block 8 to prevent the support platform 23 from moving, thereby preventing the support platform 23 from slipping off the top of the slide 5.

[0042] In a further preferred embodiment of the present invention, Figure 5As shown, the Y-axis translation system 7 includes a Y-axis motor 71, an eccentric block 72, a push rod 73, a guide assembly 74 and a fixed table 75. The top of the support table 23 is fixedly connected to a right-angle commutator 12 for vertical transmission, the input end of the right-angle commutator 12 is fixedly connected to the Y-axis motor 71, the output shaft of the right-angle commutator 12 is fixedly connected to the eccentric block 72, the outer wall edge of the eccentric block 72 is connected to the fixed table 75 through the push rod 73, and the bottom of the fixed table 75 is connected to the support table 23 through the guide assembly 74.

[0043] In this embodiment, when the width of the workpiece is large and the polishing wheel 34 cannot cover the cross section of the workpiece at one time, it is necessary to move the polishing device 3 along the Y axis to increase the effective polishing range of the polishing wheel 34. Figure 5 It can be found that a Y-axis motor 71 is arranged on the top of the support table 23, so that the Y-axis motor 71 drives the eccentric block 72 to rotate through the right-angle commutator 12, so that the eccentric block 72 pushes the push rod 73 to move the fixed table 75 along the Y-axis direction, thereby pushing the polishing device 3 on the top of the fixed table 75 to move, so as to increase the polishing range of the polishing device 3.

[0044] In a further preferred embodiment of the present invention, Figure 5 As shown, the guide assembly 74 is composed of a Y-axis slider 741 and a Y-axis slide rail 742, wherein the top of the support table 23 is fixedly connected to the side away from the right-angle commutator 12 with the Y-axis slide rail 742, and the top of the Y-axis slide rail 742 is connected to the fixed table 75 via the Y-axis slider 741.

[0045] In this embodiment, the Y-axis slider 741 and the Y-axis slide rail 742 can provide assistance when the fixed table 75 moves, making the movement of the fixed table 75 more stable, thereby making the movement of the polishing device 3 more stable and the polishing effect of the polishing device 3 better.

[0046] In a further preferred embodiment of the present invention, Figure 2 As shown, the polishing device 3 includes a polishing motor 31, a shaft seat 32, a transmission shaft 33 and a polishing wheel 34. The polishing motor 31 and the shaft seat 32 are respectively fixedly connected to the top two sides of the fixed platform 75. The transmission shaft 33 is rotatably connected in the shaft seat 32. One end of the transmission shaft 33 is connected to the output shaft of the polishing motor 31 through a belt drive, and the other end of the transmission shaft 33 is fixedly connected to the polishing wheel 34.

[0047] In this embodiment, the polishing motor 31 is provided so that when the polishing motor 31 is running, the transmission shaft 33 is rotated by a belt transmission, so that the transmission shaft 33 rotates with the polishing wheel 34 at high speed to achieve the effect of polishing the workpiece.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
