Description

Technical Field

[0001] This utility model relates to the field of clamping mechanism technology, specifically to a grinding wheel clamping mechanism. Background Technology

[0002] The thinning of liquid crystal glass substrates mainly employs chemical thinning technology. The process includes: encapsulation and curing, chemical thinning, post-thinning cleaning, grinding, post-grinding manual cleaning, and horizontal cleaning machine cleaning. Liquid crystal glass substrates are a crucial component of liquid crystal flat panel displays and have a very broad development prospect.

[0003] A search revealed existing technology (publication number: CN213858725U), which describes "a grinding device for producing liquid crystal glass substrates, comprising a base; a set of first support columns fixedly connected to the bottom end of the base; a set of second support columns fixedly connected to the top end of the base; a fixing plate fixedly connected to the top end of the second support columns away from the base; a grinding assembly disposed on the fixing plate; a through groove opened at the top end of the base; a movable plate slidably connected to the inner wall of the through groove, and an ejection mechanism disposed at the bottom end; the ejection mechanism disposed within the base; and a first cavity opened within the movable plate. This utility model provides a grinding device for producing liquid crystal glass substrates to solve the problem that insufficient grinding of the surface of liquid crystal substrates results in incomplete removal of surface bumps, failing to meet customer requirements, and requiring rework to reduce production efficiency."

[0004] In existing grinding equipment for producing liquid crystal glass substrates, the grinding wheels are frequently used consumables and need to be replaced regularly. However, the existing connection method between the grinding wheels and the motor drive shaft makes it inconvenient to quickly disassemble and replace them, which affects the processing efficiency of the liquid crystal glass substrates. Furthermore, some grinding wheels have shafts while others are just individual wheel structures, which makes it inconvenient to install grinding wheels with different structures.

[0021] Reference Figures 1 to 4As shown, this utility model provides a grinding wheel clamping mechanism, including: a clamping assembly 1, a first grinding assembly 2, and a second grinding wheel 3. The clamping assembly 1 includes a horizontal plate 11, and side plates 13 are connected to the lower sides of both ends of the horizontal plate 11. A threaded rod 12 is rotatably connected inside the side plate 13. A pressing block 14 and a clamping block 15 are slidably connected to the inner side of the side plate 13, and the pressing block 14 is located above the clamping block 15. The clamping block 15 is horizontally slidably connected to the inner side of the side plate 13. The first grinding assembly 2 is connected to the lower side of the clamping assembly 1, and the first grinding assembly 2 includes a first grinding wheel 21. The first grinding wheel 21 has a shaft 22 connected to its upper center, and a connecting block 24 connected to the upper end of the shaft 22. The connecting block 24 is connected to the clamping block 15. The second grinding wheel 3 includes an inner ring 33, and a keyway 31 is provided on the inner wall of the inner ring 33. A tapered shaft 32 is connected inside the keyway 31. The tapered shaft 32 is connected to the output shaft of the motor through a coupling. The upper end of the horizontal plate 11 is connected to the output shaft of the motor through a fixing plate. A key block 34 is connected to the outer wall of the tapered shaft 32. The key block 34 is slidably inserted into the keyway 31. A positioning bolt 35 is connected to the bottom of the key block 34.

[0022] Specifically, the clamping assembly 1 includes two sets of side plates 13 and threaded rods 12, and two sets of clamping blocks 15 to achieve symmetrical clamping of the connecting block 24.

[0023] The first grinding wheel 21 is a grinding wheel with a shaft 22 as in the prior art, and the connecting block 24 at the upper end of the shaft and the shaft 22 are an integrated structure.

[0024] Meanwhile, the second grinding wheel 3 is a grinding wheel with a central opening as in the prior art, and the grinding layer of the wheel body is located on the outside of the inner ring 33. The inner ring 33 is made of metal, and a through hole is opened at the bottom of the inner ring 33, which extends upward into the keyway 31.

[0025] Specifically, the bottom of the key block 34 is provided with a threaded hole, and after the key block 34 is inserted into the keyway 31, it is screwed to the positioning bolt 35 through the threaded hole.

[0026] like Figures 1 to 3In the middle, the inner side wall of the side plate 13 is provided with an opening groove 131, and a guide block 141 is slidably connected inside the opening groove 131. The guide block 141 is fixedly connected to the outer pressing block 14. The threaded rod 12 is screwed through the horizontal plate 11 and inserted into the opening groove 131. The lower end of the threaded rod 12 is rotatably connected to the upper end of the guide block 141. The lower end of the side plate 13 is provided with a horizontal guide groove 132, and a slider 154 is slidably connected inside the guide groove 132. The outer end of the slider 154 is connected to a connecting rod 152. The outer end of the connecting rod 152 is connected to the clamping block 15. A spring 153 is provided on the outer side of the connecting rod 152. The inner side wall of the clamping block 15 is provided with a slot 151. The connecting block 24 is provided with a circular structure. The outer wall of the connecting block 24 is symmetrically provided with clamping grooves 23, and the clamping grooves 23 are correspondingly engaged with the clamping block 15.

[0027] Specifically, the slot 151 has a set of vertically aligned slots on the clamping block 15, and the upper and lower ends of the slot 151 are respectively engaged with the upper and lower end faces of the connecting block 24, while the part between the slots 151 is inserted into the clamping groove 23.

[0028] Specifically, the side of the clamping block 15 facing the pressing block 14 is set as an inclined surface, so that after contacting the pressing block 14, the clamping block 15 can be driven to move horizontally. During disassembly, as the pressing block 14 moves upward away from the clamping block 15, the clamping block 15 can move outward under the action of the spring 153 and the slider 154, and thus disengage from the connecting block 24.

[0029] In use, the clamping assembly includes a threaded rod, a pressing block, and a clamping block. When installing the first grinding wheel, first align the groove on the outer wall of the connecting block at the upper end of the grinding wheel with the position of the clamping block. Then, drive the threaded rod downward to push the pressing block, causing it to contact and press the inclined surface of the clamping block downward. This moves the clamping block inward toward the connecting block until it is engaged in the groove, thus connecting the first grinding wheel. For disassembly and replacement, simply rotate the threaded rod in the opposite direction to move the clamping block outward and loosen it. The second grinding wheel, along with its inner tapered shaft, key block, and keyway, facilitates the connection of the inner ring of the second grinding wheel to the key block of the tapered shaft via the keyway on its inner wall. Then, the grinding wheel is inserted into the inner ring from the bottom using a positioning bolt and screwed onto the key block, thus achieving a fixed connection between the grinding wheel and the tapered shaft. This allows for different connection methods for different grinding wheels.

[0030] The grinding wheel clamping mechanism of this utility model can effectively solve the problems mentioned in the background technology, and achieves the effect of easy clamping and disassembly of grinding wheels based on the existing grinding wheel clamping mechanism technology, thereby improving processing efficiency.
