DETAILED DESCRIPTION

[0040] The specific implementation of the present invention will be described below with reference to the accompanying drawings.

[0041] As a specific example, Figure 1-14As shown, the tile grinding head according to the embodiment of the present invention comprises a grinding head 1 , and the grinding head 1 comprises a grinding base 12 and a grinding body 11 .

[0042] The grinding chassis 12 is made of metal and is in the shape of a disk. The grinding chassis 12 is provided with a center hole 121 coaxial with the disk. Usually, the grinding chassis 12 is evenly distributed with chassis mounting holes 129 around the axis of the center hole 121, so that the grinding body 11 can be mounted on a grinding device (not shown in the drawings) by screws or the like, and rotates with the grinding device, driving the grinding body 11 on the grinding chassis 12 to rotate, and grinding objects such as tiles through the grinding body 11.

[0043] The grinding body 11 is made of metal powder and is a rectangular parallelepiped, the cross section of the rectangular parallelepiped is a square, and the thickness of the grinding body 11 (i.e., the dimension in the direction perpendicular to the square cross section) is smaller than the width of the grinding body 11 (i.e., the length of the side of the square). For example, the grinding body 11 is made of iron-based alloy powder such as phosphorus-iron alloy powder and is made into a rectangular parallelepiped by conventional forming methods such as sintering and bonding; the grinding base 12 is made of iron-based material. It is easy to understand that the sides of the square are equal. Therefore, after the grinding body 11 is rotated ninety degrees around the center point of the positive direction in the plane where the square is located, the width of the grinding body 11 will not change; this also means that when the grinding body 11 is placed on the grinding chassis 12, it is only necessary to pay attention to making the direction of its thickness point to the axis of the grinding chassis 12, and any side of the square of the grinding body 11 can be used as the bottom surface to fit the top surface of the grinding chassis 12. There is no need to distinguish which side of the square of the grinding body 11 is used as the bottom surface to fit the top surface of the grinding chassis 12, and it can also ensure that the top surface of the grinding body 11 is roughly located in the same plane.

[0044] The manufacturing method of the grinding head 1 is as follows: after applying silver brazing flux (which is a prior art and functions to remove oxides and impurities on the surface) to the bottom end surface of the grinding body 11 and / or the top of the grinding chassis 12, the grinding body 11 is evenly distributed along the edge of the grinding chassis 12 around the axis of the grinding chassis 12, so that the thickness direction of the grinding body 11 points to the axis of the grinding chassis 12, and then the edge of the grinding chassis 12 is heated to a range of 610 to 640 degrees Celsius (the temperature is allowed to deviate from 610 by about 5% upward) by induction heating, so that the grinding body 11 is welded and fixed to the grinding chassis 12. It is easy to understand that the grinding body 11 is located above the grinding chassis 12. There is no need to weld the grinding bodies 11 to the grinding chassis 12 one by one, but a plurality of grinding bodies 11 are welded to the grinding chassis 12 at one time, which can improve production efficiency and reduce costs.

[0045] The tile grinding head production device of the embodiment of the present invention includes a welding device 2.

[0046] The welding device 2 includes a welding chassis 22 and a single-layer induction heating ring 21 that is coaxial with the welding chassis 22 (for example, if the induction heating ring 21 is spiral, it is a multi-layer induction heating ring 21). It is easy to understand that the induction heating ring 21 is the output end of the induction heating device (not shown in the drawings), and its overall shape is annular and its cross-section is circular. Because it needs to be connected to the induction heating device, it has two power terminals 211, and there is a ring gap 219 between the two power terminals 211. Therefore, the part of the ring gap 219 is a circular gap of the induction heating ring 21 and does not have an induction heating function. Generally, the rated power of the induction heating device needs to be greater than 35kW to ensure that the edge of the grinding chassis 12 can be heated to the required temperature.

[0047] The welding chassis 22 has a uniform rotational power. For example, a chassis support column 229 is fixedly provided at the bottom end of the welding chassis 22, and the chassis support column 229 is fixedly connected to the output end of the reduction motor (not shown in the drawings), so that the welding chassis 22 has a uniform rotational power. Of course, it is also feasible to manually turn the welding chassis 22 to have a uniform rotational power under certain conditions, although the manual turning method is less safe and may not achieve a uniform speed.

[0048] The welding chassis 22 is provided with a center positioning disk 221 coaxial with the induction heating ring 21; the welding chassis 22 supports the grinding chassis 12 so that the center positioning disk 221 is embedded in the center hole 121; the induction heating ring 21 overlaps with the grinding chassis 12 in the height direction. The welding chassis 22 rotates at a uniform speed, and the grinding chassis 12 and the grinding body 11 on the grinding chassis 12 rotate at a uniform speed by means of friction, so that the edge of the grinding chassis 12 is evenly heated, which can ensure that the welding strength of each grinding body 11 and the grinding chassis 12 is relatively uniform, and improve the uniformity of each grinding head 1.

[0049] The tile grinding head production device of the embodiment of the present invention further includes a tidying device 3; the tidying device 3 includes a lifting member 31, a rotating member 32, a fixing member 33, and a one-way elastic member 34 arranged on the inner wall of the fixing member 33. Generally, the tidying device 3 further includes a frame 39, and the frame 39 is provided with a fixing member connecting arm 393 connected to the fixing member 33, so that the fixing member 33 maintains its position.

[0050] The lifting member 31 is provided with a lifting partition 311 and a support platform 313, and two adjacent lifting partitions 311 and a support platform 313 are enclosed to form a lifting accommodating groove 312. It is easy to understand that the top and outer side of the lifting accommodating groove 312 (i.e., the direction away from the axis of the lifting member 31) are both connected to the outside of the lifting member 31. The width of the lifting accommodating groove 312 is slightly larger than the width of the grinding body 11, so the grinding body 11 can only stand upright in the lifting accommodating groove 312 (i.e., the square of the grinding body 11 stands upright), and there is a small gap between the grinding body 11 and the side wall of the lifting accommodating groove 312, and it will not be stuck in the lifting accommodating groove 312.

[0051] The rotating member 32 includes a circular ring wall 322 and an inclined groove wall 321 with a rotating power; the lifting member 31 is fitted with the inner wall of the circular ring wall 322. It is easy to understand that the inner wall of the inclined groove wall 321 gradually approaches the lifting member 31 from top to bottom. For example, the inner wall of the inclined groove wall 321 is a truncated cone-shaped side. When the grinding body 11 is located in the inclined groove wall 321, it will tend to approach the lifting member 31 due to its own weight. For example, the inclined groove wall 321 and the circular ring wall 322 are two separate parts. The circular ring wall 322 does not rotate but only the inclined groove wall 321 rotates. It can also be like Fig.12 As shown, the inclined groove wall 321 and the annular wall 322 are integrated, and the frame 39 is provided with a cylindrical rotating connecting frame 392, and the rotating connecting frame 392 is fitted with the annular wall 322 or connected through an annular bearing, and the side wall of the annular wall 322 is provided with an annular rack (not shown in the drawings), and the rotating power member 329 is a gear driven by a motor, and the gear is meshed with the annular rack, and the rotation of the gear drives the annular wall 322 and the inclined groove wall 321 to rotate.

[0052] The lifting member 31 has lifting power and the stroke of the lifting power is an integer multiple of the width of the grinding body 11 (i.e., the side length of the square of the grinding body 11). For example, the lifting member 31 is driven by a lifting power member 319 such as a cylinder or an electric cylinder to have lifting power, and by limiting the lifting power member 319 or by designing the stroke of the lifting power member 319, the lifting and lowering strokes of the lifting member 31 are both the width of the grinding body 11.

[0053] The fixing member 33 is arranged between the lifting member 31 and the inclined groove wall 321 in the horizontal direction. It is easy to understand that the fixing member 33 is arranged on the periphery of the lifting member 31 but is located inside the inclined groove wall 321; a sliding gap 35 is arranged between the bottom end of the fixing member 33 and the bottom end of the inclined groove wall 321, and the thickness of the sliding gap 35 is less than (not including equal to) twice the thickness of the grinding body 11. It is easy to understand that the thickness of the sliding gap 35 is less than twice the thickness of the grinding body 11, and theoretically only one grinding body 11 is allowed to pass through the sliding gap 35; of course, the thickness of the sliding gap 35 is usually between 1.2 and 1.5 of the thickness of the grinding body 11. A guiding inclined surface 331 is arranged at the bottom end of the inner wall of the fixing member 33 to ensure that the grinding body 11 smoothly enters the fixing member 33 from bottom to top.

[0054] When the lifting member 31 descends to the lowest position, the supporting platform 313 is lower than the bottom end of the inclined groove wall 321 .

[0055] The one-way elastic member 34 can abut against the side of the grinding body 11 (i.e., one side of the square of the grinding body 11) and only allow the grinding body 11 to move upward. For example, the one-way elastic member 34 is a rubber protrusion and has elasticity. The cross section of the rubber protrusion is a right triangle, the right angle side of the right triangle is at the top and the hypotenuse is at the bottom. The rubber protrusion is multi-layered, and the cross section of the multi-layer rubber protrusion is serrated; the one-way elastic member 34 abuts against the side of the grinding body 11, and when the grinding body 11 moves upward, the grinding body 11 abuts against the hypotenuse of the right triangle of the rubber protrusion, and it is easier to compress the rubber protrusion, and then it can pass through the rubber protrusion upward; when the grinding body 11 has a tendency to move downward, the grinding body 11 abuts against the hypotenuse of the right triangle of the rubber protrusion, or against the right angle side of the right triangle of the rubber protrusion, and it is difficult to compress the rubber protrusion, and then it cannot pass through the rubber protrusion downward. Of course, the one-way elastic member 34 may also be an embodiment described later, but its principle is the same as that of the rubber protrusion only allowing the polishing body 11 to move upward.

[0056] The working principle is as follows: Fig.12 , 13As shown, multiple grinding bodies 11 are placed in the inclined groove wall 321, and multiple grinding bodies 11 are stacked in the inclined groove wall 321 and have a tendency to move toward the lifting member 31 (as shown by arrow ARR1); at the same time, the inclined groove wall 321 rotates and drives the grinding bodies 11 therein to rotate; in this process, since the thickness of the sliding gap 35 is less than (not including equal to) twice the thickness of the grinding body 11, only a single grinding body 11 can pass through the sliding gap 35 due to its thickness. If the single grinding body 11 passing through the sliding gap 35 is facing the lifting accommodation groove 312, it will enter the lifting accommodation groove 312 and stand upright on the abutment platform 313; if the single grinding body 11 passing through the sliding gap 35 is misaligned with the lifting accommodation groove 312 and is abutted by the lifting partition 311 and cannot enter the lifting accommodation groove 312, it will change its position and posture as the inclined groove wall 321 rotates until the grinding body 11 enters the lifting accommodation groove 312 and stands upright on the abutment platform 313.

[0057] The lifting member 31 rises (as shown by arrow 2 ARR2), and the abutting platform 313 abuts the upright grinding body 11 to move upward until it passes the one-way elastic member 34 and is abutted and held in position by the one-way elastic member 34. Then, the lifting member 31 descends, and the grinding body 11 is held in position by the one-way elastic member 34 and does not descend with the lifting member 31. Usually, the lifting and lowering of the lifting member 31 and the rotation of the rotating member 32 are not performed simultaneously. In other words, when the lifting member 31 is lifted, the rotating member 32 stops rotating, and when the rotating member 32 rotates, the lifting member 31 stops lifting and lowering; however, it is not excluded that the lifting and lowering of the lifting member 31 and the rotation of the rotating member 32 are performed simultaneously.

[0058] Repeat the above process, and multiple upright grinding bodies 11 are stacked in the lifting and accommodating grooves 312 until the lifting and accommodating grooves 312 are filled. It should be noted that since multiple lifting and accommodating grooves 312 are evenly distributed around the axis of the lifting member 31, and the probability of the grinding body 11 entering each lifting and accommodating groove 312 is random, the number of layers of grinding bodies 11 in each lifting and accommodating groove 312 will be different. Therefore, when all the lifting and accommodating grooves 312 are filled with grinding bodies 11, some of the grinding bodies 11 in the lifting and accommodating grooves 312 will exceed the top of the lifting and accommodating grooves 312 and be exposed. For the grinding bodies 11 that exceed the lifting and accommodating grooves 312, they need to be manually or mechanically pulled back (as shown by arrow three ARR3) to enter the inclined groove wall 321. The implementation method can make the grinding bodies 11 evenly arranged circumferentially.

[0059] As one of the specific implementations, the tile grinding head production device of the embodiment of the present invention is as follows: Fig.14As shown, the circulatory frame 4 and the binding ring 5 that can surround the side of the circulatory frame 4 are also included; the circulatory frame 4 includes a circulatory frame 41, and the side wall of the circulatory frame 41 is provided with a circulatory separator 411; between two adjacent circulatory separators 411 is a circulatory receiving groove 412, and the circulatory frame 41 is detachably fixed to the top of the lifting member 31, so that the circulatory receiving groove 412 and the lifting receiving groove 312 are completely overlapped when viewed from above, and the circulatory frame 41 is provided with a fixing structure 413, and the fixing structure 413 is a threaded hole, a fixing pin or a quick clamp, etc., and the fixing structure 413 enables the circulatory frame 41 to be temporarily fixed to the top of the lifting member 31. It is easy to understand that the top of the fixing member 33 is also extended to be flush with the top of the circulatory frame 41 or exceed the top of the circulatory frame 41, and the unidirectional elastic member 34 in the fixing member 33 also needs to be extended upward. The grinding bodies 11 that extend beyond the top of the lifting and lowering accommodating grooves 312 enter the circulation accommodating grooves 412 until all the circulation accommodating grooves 412 are filled with the grinding bodies 11. Then, the lifting member 31 is operated (through conventional control means) to slowly rise, so that the circulation frame 41 and the grinding bodies 11 extend beyond the top of the fixing member 33. Then, the binding ring 5 is placed around the side of the circulation frame 41 to fix the grinding bodies 11 in each circulation accommodating groove 412. At this time, the evenly arranged grinding bodies 11 are moved to the grinding chassis 12 through the circulation frame 4 and the binding ring 5. Then, the binding ring 5 is removed, and the circulation frame 4 is moved upward, so that each grinding body 11 can be evenly placed on the grinding chassis 12, thereby improving the placement efficiency and accuracy of the grinding bodies 11. The binding ring 5 can be a cloth rope for binding, or an elastic ring such as a rubber ring with a circular cross section. Since the circular rubber ring can roll and surround the side of the circulation frame 41, it is more convenient to use. It should be noted that the thickness of the turnover frame 41 is equal to the width of the grinding body 11 to correspond to a single-layer grinding body 11. Although the thickness of the turnover frame 41 can correspond to multiple layers of grinding bodies 11, since only a single-layer grinding body 11 is usually welded on the grinding body 11, the need to correspond to multiple layers of grinding bodies 11 is not common. Usually, the turnover frame 41 is fixedly provided with a handle 49, so that the turnover frame 4 and the grinding body 11 can be transferred to the grinding chassis 12 on the welding chassis 22 through the handle 49.

[0060] As one of the specific implementations, the tile grinding head production device of the embodiment of the present invention also includes an alignment mechanism 6; the alignment mechanism 6 includes a circular ring alignment body 61 and a circular ring alignment groove 62 for radial alignment, and a circumferential alignment tooth 63 and a circumferential alignment groove 64 for circumferential alignment. The bottom end of the circulation frame 41 is provided with a circular ring alignment groove 62, and the top end of the lifting member 31 is provided with a circular ring alignment body 61, and the circular ring alignment body 61 is embedded in the circular ring alignment groove 62; it can ensure that the lifting member 31 and the circulation frame 41 are radially aligned; and / or, one of the bottom end of the circulation frame 41 and the top end of the lifting member 31 is provided with a circumferential alignment tooth 63, and the other is provided with a circumferential alignment groove 64, and the circumferential alignment tooth 63 is embedded in the circumferential alignment groove 64, and the central angle corresponding to the circumferential alignment tooth 63 is equal to the central angle corresponding to the lifting accommodation groove 312; it can ensure that the circulation accommodation groove 412 and the lifting accommodation groove 312 completely overlap when viewed from above.

[0061] It should be noted that, similar to the aforementioned grinding body 11 that exceeds the top of the lifting and lowering accommodating groove 312, there will also be grinding bodies 11 that exceed the rotating accommodating groove 412 after the rotating frame 41 is set. For the grinding body 11 that exceeds the rotating accommodating groove 412, it is also necessary to push it back into the inclined groove wall 321. As one of the specific implementations, the top of the rotating frame 41 is fixedly provided with an anti-drop plate 48 that covers the inner cavity of the rotating frame 41. It can prevent the grinding body 11 that exceeds the rotating accommodating groove 412 from falling from the rotating frame 41 into the lifting member 31. In order to facilitate the coaxial centerline of the rotating frame 41 when the rotating frame 41 is placed on the welding chassis 22, the center positioning plate 221 extends a circular column (not shown in the figure), and a circular hole (not shown in the figure) is provided at the bottom end of the anti-drop plate 48, and the circular column can be embedded in the circular hole, which can ensure that the rotating frame 41 is placed on the welding chassis 22. Of course, the thickness of the anti-drop plate 48 needs to be increased accordingly, which will lead to an increase in the weight of the turnover rack 4.
