Description

Technical Field

[0001] The invention belongs to the technical field of wear-resistant ball grinding, in particular to a device for quickly grinding the surface of a wear-resistant ball. Background Art

[0002] The grinding process of wear-resistant balls can be divided into different grinding equipment or grinding processes according to the purpose of the product. For example, if the grinding medium is used in a ball mill, the vortex grinding groove can be used for continuous grinding without considering the accuracy. However, for wear-resistant balls with high precision requirements, they need to be finely ground in batches.

[0003] A Chinese patent with publication number CN220718789U discloses a device for quickly grinding the surface of a wear-resistant ball, which relates to the field of wear-resistant ball processing technology. It includes a box body, a first electric telescopic rod is fixedly installed on the top inner side of the box body, and an upper grinding disc is fixedly installed on the output end of the first electric telescopic rod, and an automatic material stripping and grinding assembly and a material stripping buffer assembly are arranged at the bottom inner side of the box body. The automatic material stripping assembly includes a base, a motor, an outer grinding disc, an inner grinding disc, a bead groove, a top block, a slide rod, a reset spring, a second electric telescopic rod and a top plate; in the technical solution provided by the utility model, after the surface of the wear-resistant ball is quickly ground, the motor stops working, and then the first electric telescopic rod drives the upper grinding disc to rise. At this time, the second electric telescopic rod pushes the top plate, and then pushes the bottom of the slide rod to make the inner grinding disc rise. Under the action of the top block, the wear-resistant ball is pushed out of the bead groove and rolls to both sides of the top block, so that several wear-resistant balls can be stripped at the same time, which is convenient for use.

[0004] In the current existing technology, a telescopic rod is used to drive the upper grinding disc and the inner grinding disc to separate, so that the wear-resistant balls are fixed out of the bead groove under the action of the top block. It can be understood that in the above-mentioned existing technology, the removal of the wear-resistant balls requires a separate step, or even two or three steps to complete, and the action of removing the wear-resistant balls is different from the wear-resistant ball processing steps.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figures 1 to 10 As shown, a device for rapidly polishing the surface of a wear-resistant ball according to an embodiment of the present invention comprises:

[0036] A lower grinding disc 11 fixedly connected to the base 10, and an upper grinding disc 30 corresponding to the lower grinding disc 11, wherein a driving shaft 40 is fixedly connected to the center of the upper grinding disc 30;

[0037] The lower grinding disc 11 is provided with a plurality of troughs 111 for carrying the wear-resistant ball bodies 20; the lower grinding disc 11 is also slidably connected to a movable support plate 12, and a plurality of movable support plates 12 are provided, corresponding to the troughs 111; a pressing block 13 corresponding to the movable support plate 12 is also provided in the middle of the lower grinding disc 11, and the pressing block 13 is used to limit the return of the movable support plate 12;

[0038] When the wear-resistant ball body 20 is placed in the material trough 111, the movable support plate 12 bears part of the pressure and slides downward, and contacts the pressure block 13 and is restricted from resetting. When the upper grinding disc 30 is merged with the lower grinding disc 11 under the action of the drive shaft 40, the pressure block 13 contracts, and the restriction on the resetting of the movable support plate 12 is cancelled. After the upper grinding disc 30 is lifted, the movable support plate 12 can be reset to drive the polished wear-resistant ball body 20 to separate from the material trough 111.

[0039] In one embodiment of the present invention, compared with the prior art, when the present invention is implemented, the wear-resistant ball body 20 to be processed is directly placed in the material trough 111. Since the movable support plate 12 can slide up and down in the material trough 111, the top surface of the movable support plate 12 should be higher than the top surface of the material trough 111 in the initial state. When the wear-resistant ball is placed in the material trough 111, the movable support plate 12 can be driven to slide downward based on pressure, and combined with external force (in this embodiment, the external force is human power) to make the top surface of the movable support plate 12 flush with the top surface of the material trough 111. At this time, the movable support plate 12 and the pressing block 13 form a snap-fitting relationship, and the loading of the wear-resistant ball body 20 is completed as described above. Subsequently, the drive shaft 40 is controlled to drive the upper grinding disc 30 to move downward until the upper grinding disc 30 is merged with the lower grinding disc 11. The driving motor drives the upper grinding disc 30 to rotate, so that there is relative rotation between the upper grinding disc 30 and the lower grinding disc 11, thereby realizing the grinding of the wear-resistant ball body 20. After a period of continuous processing, the wear-resistant ball body 20 can be fully ground; finally, the upper grinding disc 30 is separated from the lower grinding disc 11 under the action of the driving shaft 40. When the upper grinding disc 30 is separated from the lower grinding disc 11, the movable support plate 12 drives the processed wear-resistant ball body 20 to move upward again, so that the wear-resistant ball body 20 is separated from the material trough 111 and slides out through the edge of the lower grinding disc 11. A track for guiding the processed wear-resistant ball body 20 can be installed at the edge of the lower grinding disc 11. When the wear-resistant ball body 20 is separated from the material trough 111, it can fall into the track, thereby completing the collection of the processed wear-resistant ball body 20;

[0040] It is worth noting that in the above process, during the loading stage, the movable support plate 12 is able to contact the pressure block 13 based on human power, and is limited by the pressure block 13 and cannot be reset; when the upper grinding disc 30 and the lower grinding disc 11 are merged, the pressure block 13 is squeezed and produces a centripetal radial displacement, and then separates from the movable support plate 12. That is to say, when the upper grinding disc 30 and the lower grinding disc 11 are merged, the limit of the movable support plate 12 by the pressure block 13 during the loading stage is cancelled, and when the upper grinding disc 30 and the lower grinding disc 11 are separated, it is not The limited movable support plate 12 can automatically pop out the wear-resistant ball body 20. Based on the above, during the loading stage, when the upper grinding disc 30 and the lower grinding disc 11 are not merged, it is ensured that the wear-resistant ball body 20 can be stably loaded in the material trough 111 and will not be carried out by the movable support plate 12. When the processing is completed, the upper grinding disc 30 is separated from the lower grinding disc 11, and the wear-resistant ball body 20 is ejected again using the movable support plate 12. Only loading is required, and there is no need to operate the unloading process of the wear-resistant ball body 20, which can improve the efficiency of wear-resistant ball processing.

[0041] like Figures 1 to 2 As shown, a plurality of vertical rods 102 are fixedly connected to the base 10, and the vertical rods 102 correspond to the movable support plate 12; a circular hole 121 is opened at the bottom of the movable support plate 12, and the vertical rods 102 pass through the circular hole 121; a first spring 122 is also sleeved on the vertical rod 102, and the two ends of the first spring 122 are respectively fixed between the bottom surface of the circular hole 121 and the base 10.

[0042] As mentioned above, the movable support plate 12 can be slidably connected to the lower grinding disc 11. In one embodiment of the present invention, a circular hole 121 is provided at the bottom of the movable support plate 12, and is inserted into the vertical rod 102 on the base 10. In order to achieve the automatic pop-up of the wear-resistant ball body 20 by the movable support plate 12 after the upper grinding disc 30 is separated from the lower grinding disc 11, a first spring 122 is also required to be provided. The first spring 122 can store force when the movable support plate 12 is limited by the pressure block 13. When the pressure block 13 is separated from the movable support plate 12, the first spring 122 can use the elastic force to quickly push the movable support plate 12 and the wear-resistant ball body 20, so that the wear-resistant ball body 20 can be automatically popped out. It is worth noting that the elastic force released after the first spring 122 is compressed should be greater than the gravity of the movable support plate 12 and the wear-resistant ball body 20, so that the wear-resistant ball body 20 can be automatically popped out after the first spring 122 is released.

[0043] like Figures 1 to 4 As shown, the movable support plate 12 is further fixed with an extension block on one side facing the pressing block 13, and the extension block is snap-fitted with the pressing block 13; a second movable groove 113 is opened in the middle of the lower grinding disc 11, and the pressing block 13 is slidably connected in the second movable groove 113.

[0044] In the above embodiment, when the wear-resistant ball body 20 is loaded in the material trough 111, it is necessary to manually squeeze the movable support plate 12 to move it downward. During this process, the extension block on one side of the movable support plate 12 will slide downward synchronously and contact the side of the pressure block 13. The side of the pressure block 13 is provided with an inclined surface, so that after being squeezed by the movable support plate 12, it can be displaced radially in the centripetal direction, and when the extension block is attached to the base 10, the pressure block 13 is reset, thereby limiting the movable support plate 12. It is worth noting that a fourth spring (not shown in the figure) is also provided in the second movable groove 113, and the fourth spring is used to drive the pressure block 13 to reset.

[0045] like Figures 1 to 4 As shown, a first movable groove 101 is provided in the base 10, and a clamping block 141 is slidably connected in the first movable groove 101, and a second spring 142 is fixed to the bottom of the clamping block 141, and the two ends of the second spring 142 are respectively fixed between the first movable groove 101 and the clamping block 141; a clamping groove 131 is provided at the bottom of the pressing block 13, and the clamping block 141 is clamped and matched with the clamping groove 131; when the upper grinding disc 30 and the lower grinding disc 11 are merged, the pressing block 13 is squeezed and displaced centripetally, canceling the limit on the movable support plate 12, and at the same time moving the clamping groove 131 to the position of the clamping block 141, forming a clamping and matching relationship.

[0046] According to the above, when the upper grinding disc 30 and the lower grinding disc 11 are merged, the limiting effect of the pressure block 13 on the movable support plate 12 is cancelled. In one embodiment of the present invention, when the upper grinding disc 30 and the lower grinding disc 11 are merged, the pressure block 13 will be squeezed again and displaced radially toward the centripetal direction, thereby canceling the limiting effect on the movable support plate 12. In order to prevent the fourth spring from driving the pressure block 13 to reset, a clamping block 141 is provided on the base 10. When the pressure block 13 displaces radially toward the centripetal direction, it can slide and cooperate with the clamping block 141, and finally engage with the clamping block 141, thereby limiting the reset of the pressure block 13. After the upper grinding disc 30 and the lower grinding disc 11 are separated, the movable support plate 12 can drive the wear-resistant ball body 20 to automatically pop out.

[0047] On this basis, it is worth noting that during the loading stage, the pressing block 13 is squeezed by the extension block and will be displaced radially in the centripetal direction. After the upper grinding disc 30 and the lower grinding disc 11 are merged, that is, during the grinding stage, the pressing block 13 will be displaced radially in the centripetal direction under the action of the upper grinding disc 30. The two displacement directions are the same. Therefore, it is also necessary to avoid the pressing block 13 and the clamping block 141 from being engaged with each other during the loading stage. Therefore, it can be understood that the extension block squeezes the pressing block 13, causing the amount of displacement of the pressing block 13 to be smaller than the amount of displacement of the pressing block 13 when the upper grinding disc 30 squeezes the pressing block 13. That is to say, during the loading stage of the wear-resistant balls, the pressing block 13 is squeezed by the extension block and the amount of centripetal radial displacement is very small.

[0048] like Figures 1 to 6 、 Figures 9 and 10As shown, the bottom of the upper grinding disc 30 is rotatably connected to a mounting plate 31, and a circular groove 311 is provided on the mounting plate 31; a single grinding plate 32 is provided between the mounting plate 31 and the upper grinding disc 30, and the single grinding plate 32 is rotatably connected in the circular groove 311; a plurality of single grinding plates 32 are provided, and correspond to the material trough 111; when the upper grinding disc 30 rotates, relative sliding occurs with the plurality of single grinding plates 32, driving the plurality of single grinding plates 32 to rotate.

[0049] After the traditional upper grinding disc 30 is merged with the lower grinding disc 11, the wear-resistant ball body 20 is polished using the grinding grooves in the lower grinding disc 11 and the upper grinding disc 30. Since the rotation direction of the upper grinding disc 30 is fixed, the wear-resistant ball body 20 loaded in the material trough 111 may only rotate in one direction and is not fully polished. In one embodiment of the present invention, after the upper grinding disc 30 is merged with the lower grinding disc 11, a driving motor is used to drive the upper grinding disc 30 to rotate. After the upper grinding disc 30 rotates, it can drive several single grinding plates 32 to rotate in the mounting plate 31. When the single grinding plates 32 rotate, they can drive the wear-resistant ball body 20 to rotate in another direction, which is different from the direction in which the upper grinding disc 30 drives the wear-resistant ball body 20 to move. Therefore, based on the superposition of multiple directions, the wear-resistant ball body 20 is fully polished.

[0050] like Figures 1 to 6 As shown, a toothed disc 301 is fixedly connected to the bottom of the upper grinding disc 30, and the toothed disc 301 is engaged with the teeth set on the outer edge of the single grinding plate 32. When the upper grinding disc 30 rotates, the single grinding plate 32 is driven to rotate through the toothed disc 301; a cover plate 33 is also fixedly connected to the bottom of the upper grinding disc 30 corresponding to the toothed disc 301; an adjusting member is provided between the cover plate 33 and the toothed disc 301; the adjusting member is used to clamp the mounting plate 31.

[0051] The above embodiment points out that when the upper grinding disc 30 rotates, it can drive several individual grinding discs to rotate. Specifically, in one embodiment of the present invention, the toothed disc 301 provided at the bottom of the upper grinding disc 30 can engage with the teeth on the edge of the individual grinding plate 32 when the upper grinding disc 30 rotates, thereby driving several individual grinding plates 32 to rotate. It should be noted here that the teeth on the edges of several individual grinding plates 32 do not contact each other to avoid jamming. Relying on the engagement of the toothed disc 301 and the teeth, when the upper grinding disc 30 rotates, the individual grinding plates 32 rotate, thereby driving the wear-resistant ball body 20 to adjust in multiple directions, thereby achieving comprehensive grinding of the wear-resistant ball body 20. On this basis, since the individual grinding plates 32 are arranged between the upper grinding disc 30 and the mounting plate 31, the mounting plate 31 and the upper grinding disc 30 are rotatably connected. In one embodiment, relying on the adjusting member, when the mounting plate 31 is sleeved on the bottom of the upper grinding disc 30, the adjusting member can be used to complete the snap-fitting of the mounting plate 31 and the upper grinding disc 30.

[0052] like Figures 1 to 7 As shown, the adjusting member includes an extrusion block 34, a connecting rod 35 and a screw 332; the extrusion block 34 is displaced along the axis in the gap between the toothed disc 301 and the cover plate 33; the connecting rod 35 is radially displaced in the gap between the toothed disc 301 and the cover plate 33. When the extrusion block 34 is displaced from the cover plate 33 to the toothed disc 301, the connecting rod 35 is centrifugally displaced radially and forms a snap-fitting relationship with the side edge of the mounting plate 31; the screw 332 is threadedly connected to the middle of the cover plate 33, and the screw 332 is screwed inward to drive the extrusion block 34 to move.

[0053] In one embodiment, when the mounting plate 31 is sleeved on the bottom of the upper grinding disc 30, the screw 332 is screwed inward to squeeze the extrusion block 34 for axial displacement. When the extrusion block 34 is displaced from the cover plate 33 to the toothed disc 301, the lateral inclined surface of the extrusion block 34 is used to squeeze and contact the end of the connecting rod 35, thereby driving the centrifugal radial displacement of the connecting rod 35. After the centrifugal radial displacement, the connecting rod 35 can pass through the side walls of the cover plate 33 and the toothed disc 301, and be inserted into the side edge of the mounting plate 31 to form a snap-fit ​​relationship. Thereafter, when the upper grinding disc 30 rotates, the connection is achieved through the snap-fit ​​relationship between the connecting rod 35 and the mounting plate 31.

[0054] like Figures 1 to 7 As shown, a circular plate 36 is further provided between the upper grinding disc 30 and the drive shaft 40. The circular plate 36 is embedded in the upper grinding disc 30. A vertical limiting rod 361 is fixed to the bottom of the circular plate 36, and the limiting rod 361 passes through the middle of the upper grinding disc 30. The extrusion block 34 is slidably connected to the limiting rod 361; a third spring 362 is sleeved on the limiting rod 361, and both ends of the third spring 362 are fixed between the end of the extrusion block 34 and the circular plate 36.

[0055] In order to ensure that the extrusion block 34 can be axially displaced under the action of the screw 332, in this embodiment, the extrusion block 34 is slidably connected to the limit rod 361, and the limit rod 361 is vertically fixed to the circular plate 36. The circular plate 36 is coaxially arranged with the upper grinding disc 30, so the limit rod 361 is also coaxial with the upper grinding disc 30. When the extrusion block 34 is squeezed by the screw 332 and axially displaced, it is specifically slidably connected to the limit rod 361, and during the displacement process, the third spring 362 will be squeezed to store force. When the screw 332 is unscrewed, the elastic force of the third spring 362 can be used to drive the extrusion block 34 to reset, thereby driving the connecting rod 35 to reset.

[0056] like Figures 1 to 5 As shown, a plurality of push rods 331 are fixed to the bottom of the cover plate 33 , and the push rods 331 correspond to the pressing blocks 13 .

[0057] In the above embodiment, it is proposed that when the upper grinding disc 30 and the lower grinding disc 11 are merged, the pressing block 13 will be squeezed and displaced radially in the centripetal direction. In this embodiment, when the upper grinding disc 30 and the lower grinding disc 11 are merged, the cover plate 33 at the bottom of the upper grinding disc 30 will move synchronously, and the support rod 331 at the bottom of the cover plate 33 will contact the inclined surface of the side wall of the pressing block 13, thereby squeezing the pressing block 13 to displace radially in the centripetal direction.

[0058] like Figures 1 to 5 As shown, an inward recessed portion is provided on the lower grinding disc 11 corresponding to the cover plate 33, and a clearance groove 112 is provided on the edge of the recessed portion. When the upper grinding disc 30 and the lower grinding disc 11 are merged, the support rod 331 at the bottom of the cover plate 33 slides with the inclined surface of the edge of the pressing block 13 to drive the pressing block 13 to move radially in the centripetal direction, thereby canceling the limit on the movable support plate 12.

[0059] As mentioned above, the cover plate 33 that moves with the upper grinding disc 30 can be retracted in the recessed portion after the upper grinding disc 30 and the lower grinding disc 11 are merged, and the push rod 331 at the bottom of the cover plate 33 can be movably connected to the clearance groove 112. When the push rod 331 moves downward, it squeezes the pressure block 13, causing the pressure block 13 to move radially toward the center and engage with the clamping block 141. As the upper grinding disc 30 rotates, the push rod 331 can slide circumferentially in the clearance groove 112 to avoid getting stuck. After the upper grinding disc 30 and the lower grinding disc 11 are separated, the movable support plate 12 can automatically pop out and drive the wear-resistant ball body 20 to separate from the material trough 111.

[0060] Working principle: directly place the wear-resistant ball body 20 to be processed into the material trough 111. Since the movable support plate 12 can slide up and down in the material trough 111, in the initial state, the top surface of the movable support plate 12 should be higher than the top surface of the material trough 111. When the wear-resistant ball is placed in the material trough 111, the movable support plate 12 can be driven to slide downward based on pressure, and combined with external force, the top surface of the movable support plate 12 is flush with the top surface of the material trough 111. At this time, the movable support plate 12 and the pressing block 13 form a snap-fitting relationship, and the loading of the wear-resistant ball body 20 is completed. Subsequently, the drive shaft 40 is controlled to drive the upper grinding disc 30 to move downward until the upper grinding disc 30 is merged with the lower grinding disc 11, and the drive motor is used to drive the upper grinding disc 30 to rotate, so that the upper grinding disc 3 0 and the lower grinding disc 11 rotate relative to each other, thereby realizing the grinding of the wear-resistant ball body 20. After continuous processing for a period of time, the wear-resistant ball body 20 can be fully ground; finally, the upper grinding disc 30 is separated from the lower grinding disc 11 under the action of the drive shaft 40. When the upper grinding disc 30 is separated from the lower grinding disc 11, the movable support plate 12 drives the processed wear-resistant ball body 20 to move upward again, so that the wear-resistant ball body 20 is separated from the material trough 111 and slides out through the edge of the lower grinding disc 11. A track for guiding the processed wear-resistant ball body 20 can be installed at the edge of the lower grinding disc 11. When the wear-resistant ball body 20 is separated from the material trough 111, it can fall into the track, thereby completing the collection of the processed wear-resistant ball body 20;

[0061] It is worth noting that in the above process, during the loading stage, the movable support plate 12 is able to contact the pressure block 13 based on human power, and is limited by the pressure block 13 and cannot be reset; when the upper grinding disc 30 and the lower grinding disc 11 are merged, the pressure block 13 is squeezed and produces a centripetal radial displacement, and then separates from the movable support plate 12. That is to say, when the upper grinding disc 30 and the lower grinding disc 11 are merged, the limit of the movable support plate 12 by the pressure block 13 during the loading stage is cancelled, and when the upper grinding disc 30 and the lower grinding disc 11 are separated, it is not The limited movable support plate 12 can automatically pop out the wear-resistant ball body 20. Based on the above, during the loading stage, when the upper grinding disc 30 and the lower grinding disc 11 are not merged, it is ensured that the wear-resistant ball body 20 can be stably loaded in the material trough 111 and will not be carried out by the movable support plate 12. When the processing is completed, the upper grinding disc 30 is separated from the lower grinding disc 11, and the wear-resistant ball body 20 is ejected again using the movable support plate 12. Only loading is required, and there is no need to operate the unloading process of the wear-resistant ball body 20, which can improve the efficiency of wear-resistant ball processing.

[0062] The movable support plate 12 is slidably connected to the lower grinding disc 11. In one embodiment of the present invention, a circular hole 121 is provided at the bottom of the movable support plate 12 and is plugged into the vertical rod 102 on the base 10. In order to realize that the movable support plate 12 can automatically pop out the wear-resistant ball body 20 after the upper grinding disc 30 is separated from the lower grinding disc 11, a first spring 122 is required to be provided. The first spring 122 can store force when the movable support plate 12 is limited by the pressure block 13. When the pressure block 13 is separated from the movable support plate 12, the first spring 122 can use the elastic force to quickly push the movable support plate 12 and the wear-resistant ball body 20, so that the wear-resistant ball body 20 can be automatically popped out. It is worth noting that the elastic force released after the first spring 122 is compressed should be large. Due to the gravity of the movable support plate 12 and the wear-resistant ball body 20, the wear-resistant ball body 20 can be automatically ejected after the first spring 122 is released; when the wear-resistant ball body 20 is loaded in the material trough 111, it is necessary to manually squeeze the movable support plate 12 to move it downward. During this process, the extension block on one side of the movable support plate 12 will slide downward synchronously and contact the side of the pressure block 13. The side of the pressure block 13 is provided with an inclined surface, so after being squeezed by the movable support plate 12, it can be displaced radially in the centripetal direction, and when the extension block is attached to the base 10, the pressure block 13 is reset, thereby limiting the movable support plate 12; it is worth noting that a fourth spring is also provided in the second movable groove 113, and the fourth spring is used to drive the pressure block 13 to reset.

[0063] When the upper grinding disc 30 and the lower grinding disc 11 are merged, the limiting effect of the pressure block 13 on the movable support plate 12 is cancelled. In one embodiment of the present invention, when the upper grinding disc 30 and the lower grinding disc 11 are merged, the pressure block 13 will be squeezed again and displaced radially in the centripetal direction, thereby canceling the limiting effect on the movable support plate 12. In order to prevent the fourth spring from driving the pressure block 13 to reset, a clamping block 141 is provided on the base 10. When the pressure block 13 displaces radially in the centripetal direction, it can slide and cooperate with the clamping block 141 and finally engage with the clamping block 141, thereby limiting the reset of the pressure block 13. After the upper grinding disc 30 and the lower grinding disc 11 are separated, the movable support plate 12 can drive the wear-resistant ball body 20 to automatically pop out.

[0064] On this basis, it is worth noting that during the loading stage, the pressing block 13 is squeezed by the extension block and will be displaced radially in the centripetal direction. After the upper grinding disc 30 and the lower grinding disc 11 are merged, that is, during the grinding stage, the pressing block 13 will be displaced radially in the centripetal direction under the action of the upper grinding disc 30. The two displacement directions are the same. Therefore, it is also necessary to avoid the pressing block 13 and the clamping block 141 from being engaged with each other during the loading stage. Therefore, it can be understood that the extension block squeezes the pressing block 13, causing the amount of displacement of the pressing block 13 to be smaller than the amount of displacement of the pressing block 13 when the upper grinding disc 30 squeezes the pressing block 13. That is to say, during the loading stage of the wear-resistant balls, the pressing block 13 is squeezed by the extension block and the amount of centripetal radial displacement is very small.

[0065] When the upper grinding disc 30 rotates, it can drive several individual grinding discs to rotate. Specifically, in one embodiment of the present invention, the toothed disc 301 provided at the bottom of the upper grinding disc 30 can engage with the teeth on the edge of the individual grinding plate 32 when the upper grinding disc 30 rotates, thereby driving several individual grinding plates 32 to rotate. It should be noted here that the teeth on the edges of several individual grinding plates 32 do not contact each other to avoid getting stuck. Relying on the engagement of the toothed disc 301 with the teeth, when the upper grinding disc 30 rotates, the individual grinding plates 32 rotate, thereby driving the wear-resistant ball body 20 to adjust in multiple directions, thereby achieving comprehensive grinding of the wear-resistant ball body 20. On this basis, since the individual grinding plate 32 is provided between the upper grinding disc 30 and the mounting plate 31, the space between the mounting plate 31 and the upper grinding disc 30 is a rotating Dynamic connection, in one embodiment, relies on an adjusting piece, and when the mounting plate 31 is sleeved on the bottom of the upper grinding disc 30, the adjusting piece can be used to complete the snap fit between the mounting plate 31 and the upper grinding disc 30; when the mounting plate 31 is sleeved on the bottom of the upper grinding disc 30, the screw 332 is screwed inward to squeeze the extrusion block 34 for axial displacement. When the extrusion block 34 is displaced from the cover plate 33 to the toothed disc 301, the lateral inclined surface of the extrusion block 34 is used to squeeze and contact the end of the connecting rod 35, thereby driving the centrifugal radial displacement of the connecting rod 35. After the centrifugal radial displacement, the connecting rod 35 can penetrate the side walls of the cover plate 33 and the toothed disc 301, and be inserted into the side edge of the mounting plate 31 to form a snap fit relationship. Thereafter, when the upper grinding disc 30 rotates, the connection is achieved through the snap fit relationship between the connecting rod 35 and the mounting plate 31.
