Description

Technical Field

[0001] This invention relates to the field of ceramic tile grinding heads and their manufacturing technology, and particularly to ceramic tile grinding heads and their manufacturing apparatus. Background Technology

[0002] Traditional tile grinding heads consist of a grinding head, a grinding base, and a grinding body. The grinding base is made of metal and is disc-shaped, with a central hole coaxial with the disc. The grinding body is made of metal powder and is a cuboid with a square cross-section; the thickness of the grinding body is less than its width. During production, multiple grinding bodies need to be welded one by one onto the grinding base, resulting in low efficiency.

[0003] In addition, the grinding media are placed manually one by one on the grinding base. Manual placement of the grinding media is relatively costly and inefficient. Furthermore, it is difficult to ensure that the grinding media are evenly distributed around the grinding base, resulting in uneven gaps between the grinding media. Summary of the Invention

[0004] One object of the present invention is to solve or alleviate the above-mentioned technical problems.

[0005] The present invention employs a ceramic tile grinding head, comprising a grinding head, a grinding base, and a grinding body. The grinding base is made of metal and is disc-shaped, with a central hole coaxial with the disc shape. The grinding body is made of metal powder and is cuboid in shape, with a square cross-section, and the thickness of the grinding body is less than its width. The grinding head is manufactured by applying silver solder to the bottom surface of the grinding body and / or the top surface of the grinding base, then evenly distributing the grinding body along the edge of the grinding base around its axis, such that the thickness of the grinding body points towards the axis of the grinding base. The edge of the grinding base is then heated to a temperature between 610 and 640 degrees Celsius using induction heating, thereby welding and fixing the grinding body to the grinding base.

[0006] The effect achieved by this invention is to improve production efficiency and reduce costs.

[0007] The present invention employs a ceramic tile grinding head production device, which includes a welding device; the welding device includes a welding base and a single-layer induction heating ring coaxial with the welding base; the welding base has a uniform rotational power; the welding base is provided with a central positioning plate coaxial with the induction heating ring; the welding base supports the grinding base such that the central positioning plate is embedded in the central hole; the induction heating ring has a portion overlapping with the grinding base in the height direction.

[0008] It can ensure that the welding strength of each grinding body and the grinding base is more uniform and improve the uniformity of each grinding head.

[0009] A further technical solution also includes a sorting device; the sorting device includes a lifting component, a rotating component, a fixing component, and a one-way elastic component disposed on the inner wall of the fixing component; the lifting component is provided with a lifting partition and a supporting platform, and two adjacent lifting partitions and supporting platforms together form a lifting receiving groove; the rotating component includes an annular wall and an inclined groove wall with rotational power; the lifting component is in contact with the inner wall of the annular wall; the lifting component has lifting power and the stroke of its lifting power is an integer multiple of the width of the grinding body; the fixing component is disposed horizontally between the lifting component and the inclined groove wall; a sliding gap is provided between the bottom end of the fixing component and the bottom end of the inclined groove wall, and the thickness of the sliding gap is less than twice the thickness of the grinding body; when the lifting component descends to the lowest position, the supporting platform is lower than the bottom end of the inclined groove wall; the one-way elastic component can abut against the side of the grinding body and only allows the grinding body to move upward.

[0010] It enables the grinding media to be evenly arranged circumferentially.

[0011] Further technical solutions also include a turnover frame and a binding ring that can surround the side of the turnover frame; the turnover frame includes a turnover frame, and the side wall of the turnover frame is provided with a turnover divider; there is a turnover receiving groove between two adjacent turnover dividers, and the turnover frame is detachably fixed to the top of the lifting component so that the turnover receiving groove and the lifting receiving groove completely overlap when viewed from above.

[0012] It enables each grinding element to be placed evenly on the grinding base, improving the placement efficiency and accuracy of the grinding elements.

[0013] A further technical solution is provided where the bottom end of the turnover frame is provided with a circular alignment groove, and the top end of the lifting component is provided with a circular alignment body, the circular alignment body being embedded in the circular alignment groove; and / or, one of the bottom end of the turnover frame and the top end of the lifting component is provided with a circumferential alignment tooth, and the other is provided with a circumferential alignment groove, the circumferential alignment tooth being embedded in the circumferential alignment groove, and the central angle corresponding to the circumferential alignment tooth being equal to the central angle corresponding to the lifting receiving groove.

[0014] It can ensure that the lifting component and the turnover frame are radially aligned; it can ensure that the turnover receiving groove and the lifting receiving groove are completely overlapped when viewed from above.

[0015] A further technical solution involves fixing a fall-prevention plate at the top of the turnover frame to cover the inner cavity of the turnover frame.

[0016] It can prevent grinding media that exceed the turnover capacity from falling from the turnover frame into the lifting component.

[0017] A further technical solution involves an upwardly extending circular column from the central positioning disk, and a circular hole at the bottom of the anti-fall plate, allowing the circular column to be inserted into the circular hole.

[0018] This ensures that the turnover frame and the welding chassis are coaxial when placed on the chassis.

[0019] A further technical solution involves providing a pusher protrusion on the inner wall of the inclined groove, with a difference between the distances from the two ends of the pusher protrusion to the axis of the rotating component.

[0020] It can improve the effect of changing the position and posture of the grinding body in the inclined groove wall, so that the grinding body has a greater chance of entering the lifting and receiving groove.

[0021] A further technical solution also includes an elastic element column and a plug. The one-way elastic element is a metal spring sheet arranged sequentially along the elastic element column, and the fixing element is provided with a cylindrical groove with an opening at the top. The elastic element column is embedded in the cylindrical groove, and the plug is screwed into the cylindrical groove and abuts against the elastic element column.

[0022] Easy to install and maintain unidirectional elastic components.

[0023] A further technical solution is that the elastic element column is provided with an elastic element slot with a T-shaped cross section; the unidirectional elastic element is a right-angled triangular frame with mounting protrusions at both ends, and the mounting protrusions are respectively embedded into the two sides of the elastic element slot so that the unidirectional elastic element is exposed from the elastic element slot.

[0024] It facilitates the assembly of unidirectional elastic elements and elastic element columns. Attached Figure Description

Detailed Implementation

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

[0041] As a specific example, such as Figure 1-14As shown, the tile grinding head of the embodiment of the present invention includes a grinding head 1, which includes a grinding base 12 and a grinding body 11.

[0042] The grinding base 12 is made of metal and is disc-shaped. The grinding base 12 has a central hole 121 that is coaxial with the disc shape. Typically, the grinding base 12 has mounting holes 129 evenly distributed around the axis of the central hole 121, so that the grinding body 11 can be mounted on the grinding equipment (not shown in the figure) by screws or the like. The grinding body 11 rotates with the grinding equipment, causing the grinding body 11 on the grinding base 12 to rotate as well, and the grinding body 11 grinds the ceramic tile and other objects.

[0043] The grinding body 11 is made of metal powder and is a cuboid with a square cross-section. The thickness of the grinding body 11 (i.e., the dimension perpendicular to the square cross-section) is less 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 ferrophosphorus alloy powder and formed into a cuboid 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 since the sides of a square are equal, the width of the grinding body 11 will not change after rotating 90 degrees around the center point of the positive direction within the plane of the square. This also means that when the grinding body 11 is placed on the grinding base 12, it is only necessary to ensure that the direction of its thickness points to the axis of the grinding base 12 and that either side of the square of the grinding body 11 is in contact with the top surface of the grinding base 12. It is not necessary to distinguish which side of the square of the grinding body 11 is in contact with the top surface of the grinding base 12, and it is also possible to ensure that the top surface of the grinding body 11 is roughly in the same plane.

[0044] The manufacturing method of the grinding head 1 is as follows: After applying silver solder flux (existing technology, its function is to remove surface oxides and impurities, etc.) to the bottom end face of the grinding body 11 and / or the top of the grinding base 12, the grinding body 11 is evenly distributed around the axis of the grinding base 12 along the edge of the grinding base 12, so that the thickness direction of the grinding body 11 points to the axis of the grinding base 12. Then, the edge of the grinding base 12 is heated to 610 to 640 degrees Celsius by induction heating (the temperature is allowed to deviate from 610 degrees Celsius by about 5%), so that the grinding body 11 is welded and fixed to the grinding base 12. It is easy to understand that the grinding body 11 is located on top of the grinding base 12. Instead of welding the grinding bodies 11 one by one to the grinding base 12, multiple grinding bodies 11 are welded to the grinding base 12 at one time, which can improve production efficiency and reduce costs.

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

[0046] The welding device 2 includes a welding base 22 and a single-layer induction heating ring 21 coaxial with the welding base 22 (for example, if the induction heating ring 21 is spiral-shaped, 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 attached diagram), and its overall shape is annular with a circular cross-section. Because it needs to be connected to the induction heating device, it has two electrical terminals 211, with a ring notch 219 between the two terminals 211. Therefore, the portion of the ring notch 219 is the annular notch of the induction heating ring 21 and does not have induction heating function. Typically, the rated power of the induction heating device needs to be greater than 35kW to ensure that the edge of the grinding base 12 can be heated to the required temperature.

[0047] The welding chassis 22 possesses a uniform rotational force. For example, a chassis support column 229 is fixedly installed at the bottom of the welding chassis 22, and the chassis support column 229 is fixedly connected to the output end of a geared motor (not shown in the attached diagram), so that the welding chassis 22 possesses a uniform rotational force. Of course, it is also feasible to achieve a uniform rotational force for the welding chassis 22 by manually turning it, although this method of manually turning it is less safe and may not be able to achieve a uniform speed.

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

[0049] The tile grinding head production apparatus of the present invention further includes a sorting device 3; the sorting device 3 includes a lifting member 31, a rotating member 32, a fixing member 33, and a one-way elastic member 34 disposed on the inner wall of the fixing member 33. Typically, the sorting device 3 also includes a frame 39, which is provided with a fixing member connecting arm 393 for connecting the fixing member 33, so that the fixing member 33 maintains its position.

[0050] The lifting component 31 is provided with a lifting partition 311 and a supporting platform 313. Two adjacent lifting partitions 311 and supporting platforms 313 together form a lifting receiving groove 312. It is easy to understand that the top and outer side (i.e., the direction away from the axis of the lifting component 31) of the lifting receiving groove 312 are connected to the outside of the lifting component 31. The width of the lifting receiving groove 312 is slightly larger than the width of the grinding body 11. Therefore, the grinding body 11 can only stand upright in the lifting receiving groove 312 (i.e., the square shape of the grinding body 11 stands upright). There is a small gap between the grinding body 11 and the side wall of the lifting receiving groove 312, so it will not get stuck in the lifting receiving groove 312.

[0051] The rotating component 32 includes an annular wall 322 and an inclined groove wall 321 with rotational power; the lifting component 31 is in contact with the inner wall of the annular wall 322. It is easy to understand that the inner wall of the inclined groove wall 321 gradually approaches the lifting component 31 from top to bottom; for example, the inner wall of the inclined groove wall 321 is the side of a frustum. When the grinding body 11 is located inside the inclined groove wall 321, it will tend to move closer to the lifting component 31 due to its own weight. For example, the inclined groove wall 321 and the annular wall 322 can be two separate components, with the annular wall 322 not rotating but only the inclined groove wall 321 rotating. Alternatively, it could be as follows... Figure 12 As shown, the inclined groove wall 321 and the annular wall 322 are integrated. The frame 39 is provided with a cylindrical rotating connecting frame 392. The rotating connecting frame 392 is attached to the annular wall 322 or connected through an annular bearing. The side wall of the annular wall 322 is provided with an annular rack (not shown in the figure). The rotating power component 329 is a gear driven by a motor. The gear meshes with the annular rack. 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 its 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 electric cylinder, and has lifting power. By limiting the lifting power member 319 or by designing the stroke of the lifting power member 319, the upward and downward strokes of the lifting member 31 are both the width of the grinding body 11.

[0053] The fixing member 33 is horizontally positioned between the lifting member 31 and the inclined groove wall 321. It is easy to understand that the fixing member 33 is located on the periphery of the lifting member 31 but within the inclined groove wall 321. A sliding gap 35 is provided between the bottom end of the fixing member 33 and the bottom end of the inclined groove wall 321. The thickness of the sliding gap 35 is less than (but not equal to) twice the thickness of the grinding body 11. It is easy to understand that since the thickness of the sliding gap 35 is less than twice the thickness of the grinding body 11, 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 times the thickness of the grinding body 11. The bottom end of the inner wall of the fixing member 33 is provided with a guide slope 331 to ensure that the grinding body 11 smoothly enters the fixing member 33 from bottom to top.

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

[0055] The one-way elastic element 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 allows the grinding body 11 to move upward. For example, the one-way elastic element 34 is a rubber protrusion with elasticity. The cross-section of the rubber protrusion is a right-angled triangle with the right-angled side at the top and the hypotenuse at the bottom. The rubber protrusion is multi-layered, and the cross-section of the multi-layered rubber protrusion is serrated. When the grinding body 11 moves upward, the one-way elastic element 34 abuts against the side of the grinding body 11, and the grinding body 11 abuts against the hypotenuse of the right-angled triangle of the rubber protrusion, making it easier to compress the rubber protrusion and thus allowing it to pass upward through the rubber protrusion. When the grinding body 11 tends to move downward, the grinding body 11 abuts against the hypotenuse of the right-angled triangle of the rubber protrusion, or against the right-angled side of the right-angled triangle of the rubber protrusion, making it more difficult to compress the rubber protrusion and thus preventing it from passing downward through the rubber protrusion. Of course, the one-way elastic element 34 can also be implemented in the manner described later, but its principle is the same as that of the rubber protrusion which only allows the grinding body 11 to move upward.

[0056] The working principle is as follows: Figure 12 , 13As shown, multiple grinding bodies 11 are placed into the inclined groove wall 321. The multiple grinding bodies 11 are stacked in the inclined groove wall 321 and tend to move towards 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 inside it to rotate. During this process, since the thickness of the sliding gap 35 is less than (not 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 a single grinding body 11 passing through the sliding gap 35 is facing the lifting receiving groove 312, it will enter the lifting receiving groove 312 and stand upright on the supporting table 313. If a single grinding body 11 passing through the sliding gap 35 is misaligned with the lifting receiving groove 312 and is held by the lifting divider 311 and cannot enter the lifting receiving groove 312, it will change its position and orientation as the inclined groove wall 321 rotates until the grinding body 11 enters the lifting receiving groove 312 and stands upright on the supporting table 313.

[0057] The lifting member 31 rises (as shown by arrow 2 ARR2), the supporting table 313 supports the vertically standing grinding body 11 and moves upward until it passes the one-way elastic member 34. After being supported and held in position by the one-way elastic member 34, the lifting member 31 descends. The grinding body 11 is held in position by the one-way elastic member 34 and does not descend with the lifting member 31. Normally, the lifting of the lifting member 31 and the rotation of the rotating member 32 do not occur simultaneously. In other words, when the lifting member 31 rises, the rotating member 32 stops rotating, and when the rotating member 32 rotates, the lifting member 31 stops rising or falling; however, it is not impossible for the lifting of the lifting member 31 and the rotation of the rotating member 32 to occur simultaneously.

[0058] Repeating the above process, multiple vertical grinding bodies 11 are stacked in the lifting receiving groove 312 until the lifting receiving groove 312 is filled. It should be noted that since the multiple lifting receiving grooves 312 are evenly distributed around the axis of the lifting component 31, the probability of the grinding body 11 entering each lifting receiving groove 312 is random, which will result in different layers of grinding bodies 11 in each lifting receiving groove 312. Therefore, when all lifting receiving grooves 312 are filled with grinding bodies 11, some grinding bodies 11 in the lifting receiving grooves 312 will protrude beyond the top of the lifting receiving groove 312. For the grinding bodies 11 that protrude beyond the lifting receiving groove 312, they need to be manually or mechanically repositioned (as shown by arrow 3 ARR3) into the inclined groove wall 321. The implementation method enables the grinding bodies 11 to be evenly arranged circumferentially.

[0059] As one specific implementation method, the tile grinding head production device of the present invention, such as... Figure 14As shown, it also includes a turnover frame 4 and a binding ring 5 that can surround the side of the turnover frame 4; the turnover frame 4 includes a turnover frame 41, and the side wall of the turnover frame 41 is provided with a turnover divider 411; there is a turnover receiving groove 412 between two adjacent turnover dividers 411. The turnover frame 41 is detachably fixed to the top of the lifting member 31, so that the turnover receiving groove 412 and the lifting receiving groove 312 completely overlap when viewed from above. The turnover frame 41 is provided with a fixing structure 413, which is a threaded hole, a fixing pin, or a quick clamp, etc. The fixing structure 413 allows the turnover 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 or beyond the top of the turnover frame 41, and the one-way elastic member 34 in the fixing member 33 also needs to be extended upward. The grinding bodies 11, extending beyond the top of the lifting receiving groove 312, enter the turnover receiving groove 412 until all turnover receiving grooves 412 are filled with grinding bodies 11. Then, the lifting component 31 (through conventional control means) is operated to slowly rise, causing the turnover frame 41 and the grinding bodies 11 to extend beyond the top of the fixing component 33. Then, the binding ring 5 is wrapped around the side of the turnover frame 41 to fix the grinding bodies 11 in each turnover receiving groove 412. At this time, the evenly arranged grinding bodies 11 are moved to the grinding base 12 by the turnover frame 4 and the binding ring 5. Then, the binding ring 5 is removed, and the turnover frame 4 is moved upward to ensure that each grinding body 11 is evenly placed on the grinding base 12, improving the placement efficiency and accuracy of the grinding bodies 11. The binding ring 5 can be a binding rope or an elastic ring such as a circular rubber ring; since the circular rubber ring can roll around the side of the turnover 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 of the grinding body 11. Although the thickness of the turnover frame 41 can correspond to multiple layers of the grinding body 11, since only a single layer of the grinding body 11 is usually welded onto the grinding body 11, the need to correspond to multiple layers of the grinding body 11 is not common. Typically, the turnover frame 41 is fixedly provided with a handle 49 to facilitate the transfer of the turnover frame 4 and the grinding body 11 to the grinding base 12 on the welding base 22 via the handle 49.

[0060] As one specific implementation, the tile grinding head production device of this invention further includes an alignment mechanism 6; the alignment mechanism 6 includes an annular alignment body 61 and an annular 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 turnover frame 41 is provided with an annular alignment groove 62, and the top end of the lifting member 31 is provided with an annular alignment body 61, which is embedded in the annular alignment groove 62; this ensures that the lifting member 31 and the turnover frame 41 are radially aligned; and / or, one of the bottom end of the turnover 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, with the circumferential alignment tooth 63 embedded in the circumferential alignment groove 64, and the central angle corresponding to the circumferential alignment tooth 63 being equal to the central angle corresponding to the lifting receiving groove 312; this ensures that the turnover receiving groove 412 and the lifting receiving groove 312 completely overlap when viewed from above.

[0061] It should be noted that, similar to the aforementioned grinding body 11 extending beyond the top of the lifting and receiving groove 312, a grinding body 11 extending beyond the turning groove 412 will also exist after the turnover frame 41 is set. For the grinding body 11 extending beyond the turning groove 412, it is also necessary to push it back into the inclined groove wall 321. As one specific implementation, a fall-prevention plate 48 covering the inner cavity of the turnover frame 41 is fixedly provided at the top of the turnover frame 41. This prevents the grinding body 11 extending beyond the turning groove 412 from falling from the turnover frame 41 into the lifting component 31. To ensure that the turnover frame 41 and the welding base 22 are coaxial when placed on the welding base 22, a circular column (not shown in the attached figure) extends upward from the center positioning plate 221. A circular hole (not shown in the attached figure) is opened at the bottom of the fall-prevention plate 48, and the circular column can be inserted into the circular hole, ensuring that the turnover frame 41 and the welding base 22 are coaxial when placed on the welding base 22. Of course, the thickness of the anti-fall plate 48 needs to be increased accordingly, which will lead to an increase in the weight of the turnover rack 4.

[0062] As one specific implementation, the inner wall of the inclined groove wall 321 is provided with a lever protrusion 323. There is a difference between the distances from the two ends of the lever protrusion 323 to the axis of the rotating member 32. For example, the lever protrusion 323 is strip-shaped and passes through the axis of the rotating member 32 when viewed from above. This can improve the effect of changing the position and posture of the grinding body 11 in the inclined groove wall 321, so that the grinding body 11 has a greater chance of entering the lifting and receiving groove 312.

[0063] As one of the specific implementation methods, such as Figure 10As shown, it also includes an elastic post 341 and a plug 345.
