Description

Technical Field

[0001] This application relates to the field of grinding wheel technology, and more specifically, to a grinding wheel for grinding glass discs. Background Technology

[0002] Edge grinding wheels are bonded abrasives used for edge processing of materials. They are mainly used in industrial fields such as glass, stone, and metal. They generally achieve rough grinding, fine grinding, and polishing through high-speed rotation. They are suitable for processing needs such as flat surfaces and irregularly shaped edges. Edge grinding wheels are also used to grind the round edges of glass discs.

[0003] Referring to Chinese invention patent publication number CN 220446218 U, entitled "An Optical Glass Disc Grinding Wheel," this invention includes a mounting plate. A positioning block is fixedly mounted on the center of the upper surface of the mounting plate, and a grinding ring is mounted on the outer side of the mounting plate. Locking blocks are mounted on both sides of the grinding ring, and an adjustment groove is formed in the center of the front side of the mounting plate. This invention, by incorporating an electromagnet, adjustment groove, and limiting rod, allows for easy replacement of the optical glass disc grinding wheel when it is damaged. Activating the electromagnet attracts the positioning block, causing the movable block and limiting rod to disengage from the locking blocks, and the locking blocks and grinding ring to detach. Conversely, the locking blocks are placed back into the locking groove. Activating the electromagnet and then deactivating it causes the tension spring to move the limiting rod outward and insert it into the limiting groove, thus reinstalling the grinding ring. This limiting structure design simplifies the disassembly and assembly process of the grinding wheel compared to existing methods, making it easier to use.

[0004] However, some problems still exist in actual use:

[0005] After prolonged grinding operations, the outer grinding area of ​​existing edge grinding wheels becomes severely worn flat, or the grinding wheel itself becomes locally damaged and cannot continue to work, requiring replacement. When replacing the entire edge grinding wheel, or when the edge grinding wheel is partially damaged, the entire wheel also needs to be replaced, resulting in resource waste and increased production costs. Therefore, a new type of glass disc edge grinding wheel is needed to solve the shortcomings of the existing system. Utility Model Content

[0006] To address the aforementioned problems, this application provides a grinding wheel for edging glass discs.

[0007] The glass disc edging grinding wheel provided in this application adopts the following technical solution:

[0008] A glass disc grinding wheel, comprising

[0009] Outline frame;

[0010] The connecting shaft is fixedly connected to the inner center of the outer frame, and threads are provided on both the inner and outer sides of the connecting shaft;

[0011] The stabilizing mechanism is movably connected to the outside of the connecting shaft.

[0012] Multiple splicing blocks are attached to the outside of the stabilizing mechanism, and each splicing block has a grinding disc on its outer side;

[0013] The protective cover is fitted onto the outside of the connecting shaft and is located directly above the stabilizing mechanism.

[0014] The limiting head is movably connected to the outside of the connecting shaft, and the limiting head is located directly above the protective cover.

[0015] Furthermore, the stabilizing mechanism includes a connecting ring, telescopic rods, compression springs, and contact plates. The telescopic rods are arranged in a ring and fixedly connected to the outside of the connecting ring. The contact plates are fixedly connected to the end of the telescopic rods away from the connecting ring. The compression springs are sleeved on the outside of the telescopic rods.

[0016] Furthermore, the connecting ring is rotatably connected to the outer bottom end of the connecting shaft, and the contact piece is arc-shaped with arc-shaped chamfers at both ends.

[0017] Furthermore, the outer frame has six fixed internal connection limit blocks, which are located in the middle of the connection seam between two splicing blocks. Both sides of the limit blocks are arc-shaped, and the distance between the two limit blocks is less than the width of the contact piece.

[0018] Furthermore, the splicing blocks are spliced ​​together in a ring and inserted into the outer wall of the outline frame. A limiting groove is opened on the rear side of the splicing block. Several inserts are fixedly connected to the bottom side of the protective cover. The limiting groove and the inserts are matched, and the inserts are inserted into the inside of the limiting groove.

[0019] Furthermore, slots are provided at both ends of the splicing block, and U-shaped strips are inserted into the inside of each slot.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] (1) By setting a stabilizing mechanism, the compression spring reacts to the arc-shaped piece, and the arc-shaped piece pulls the telescopic rod to extend and pushes the splicing block outward until the two ends of the arc-shaped piece press against the two ends of the limit block. At the same time, the connecting ring is rotated and the telescopic rod drives the arc-shaped piece to move to the surface of the limit block. This is beneficial for automatically popping out when replacing worn positions, and secondly enhances the stability of the internal connection structure of the outer frame when it rotates.

[0022] (2) By using the insert and U-shaped strip, the limiting head is rotated and removed from the connecting shaft. The protective cover is then removed. During the removal of the protective cover, the insert is disengaged from the slot. Then, the U-shaped strips at both ends of the splicing block where the grinding disc needs to be replaced are pulled out. This facilitates quick assembly and limiting of the device, and avoids shaking during use that could damage the round edge of the glass sheet or cause uneven grinding of the round edge.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] like Figure 1-4 As shown, this utility model provides a technical solution: a glass disc grinding wheel, including an outer frame 1 and a connecting shaft 2. The connecting shaft 2 is fixedly connected to the inner center of the outer frame 1. Threads are provided on both the inner and outer sides of the connecting shaft 2. A stabilizing mechanism 3 is movably connected to the outer side of the connecting shaft 2. Several splicing blocks 4 are closely attached to the outer side of the stabilizing mechanism 3. Grinding discs 5 are provided on the outer side of each splicing block 4. A protective cover 6 is fitted on the outer side of the connecting shaft 2. The protective cover 6 is located directly above the stabilizing mechanism 3. A limiting head 7 is movably connected to the outer side of the connecting shaft 2. The limiting head 7 is located directly above the protective cover 6.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the stabilizing mechanism 3 includes a connecting ring 301, a telescopic rod 302, a compression spring 303, and a contact piece 304. The telescopic rod 302 has six rods arranged in a ring and fixedly connected to the outside of the connecting ring 301. The contact piece 304 is fixedly connected to the end of the telescopic rod 302 away from the connecting ring 301. The compression spring 303 is sleeved on the outside of the telescopic rod 302. The connecting ring 301 is rotatably connected to the bottom of the outside of the connecting shaft 2. The contact piece 304 is arc-shaped, and both ends of the contact piece 304 have arc-shaped chamfers.

[0034] The compression spring 303 reacts to the arc-shaped piece, while the arc-shaped piece pulls the telescopic rod 302 to extend and push the splicing block 4 outward until the two ends of the arc-shaped piece abut against the two ends of the limiting block 8. At the same time, the connecting ring 301 is rotated and the telescopic rod 302 drives the arc-shaped piece to move to the surface of the limiting block 8. This is beneficial for automatically popping out when replacing worn positions, making operation convenient. Secondly, it enhances the stability of the internal connection structure of the outer frame 1 when it rotates.

[0035] like Figure 1 , Figure 2 and Figure 3 and Figure 4As shown, six limiting blocks 8 are fixedly connected inside the outline frame 1. The limiting blocks 8 are located in the middle of the connection seam between two splicing blocks 4. Both sides of the limiting blocks 8 are arc-shaped. The distance between the two limiting blocks 8 is less than the width of the contact piece 304. The splicing blocks 4 are spliced ​​together in a ring and inserted into the outer wall of the outline frame 1. A limiting groove 9 is opened on the rear side of the splicing block 4. Several insert pieces 10 are fixedly connected to the bottom side of the protective cover 6. The limiting groove 9 is adapted to the insert pieces 10. The insert pieces 10 are inserted into the inside of the limiting groove 9. Slots are opened at both ends of the splicing block 4. U-shaped strips 11 are inserted into the inside of the slots.

[0036] By rotating the limiting head 7 from the connecting shaft 2, the protective cover 6 is removed together. During the removal of the protective cover 6, the insert 10 is disengaged from the slot. Then, the U-shaped strips 11 at both ends of the splicing block 4 at the position where the grinding disc 5 needs to be replaced are pulled out. This facilitates quick assembly and limiting of the device and avoids shaking during use, which may damage the round edge of the glass sheet or cause uneven grinding of the round edge.

[0037] The implementation principle of a glass disc grinding wheel in this application embodiment is as follows: After long-term use, when it is necessary to replace the excessively worn grinding disc 5, firstly, the limiting head 7 is rotated off from the connecting shaft 2, and the protective cover 6 is removed together. During the removal of the protective cover 6, the insert 10 is disengaged from the slot. Next, the U-shaped strips 11 at both ends of the splicing block 4 at the position where the grinding disc 5 needs to be replaced are pulled out. At this time, the compression spring 303 reacts to the arc-shaped piece, and at the same time, the arc-shaped piece pulls the telescopic rod 302 to extend and pushes the splicing block 4 outward until the two ends of the arc-shaped piece abut against the two ends of the limiting block 8. At the same time, the connecting ring 301 is rotated and the telescopic rod 302 moves the arc-shaped piece to the surface of the limiting block 8. After the replacement is completed, the U-shaped strip 11 is inserted back into the slot. Then, the connecting ring 301 is rotated to reset the arc-shaped piece. The insert 10 is then aligned with the limiting groove 9 and sleeved on the outside of the connecting shaft 2. At the same time, the limiting head 7 is rotated to fix it.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
