Description

Technical Field

[0001] The utility model relates to the technical field of fixing mechanisms, in particular to a glass limiting fixing mechanism used for glass grinding. Background Art

[0002] The glass limit fixing mechanism is a device used to limit the position and movement of glass during glass processing or transportation. Its main function is to ensure that the glass remains stable during processing or transportation, prevent it from shifting, sliding or colliding, thereby avoiding damage and waste of the glass. This mechanism can improve the accuracy and efficiency of glass processing and reduce damage and waste of glass.

[0003] According to the search, Chinese patent document, announcement number: CN 221936549 U, discloses a fixing mechanism for glass production. The utility model relates to the field of fixing technology and discloses a fixing mechanism for glass production, which solves the problem that the current glass fixing effect is poor in the production process, affecting the processing quality of the glass. The utility model includes a processing seat, a debris groove is provided on the upper end of the processing seat, and suction cups are connected on all sides of the upper end of the processing seat. Placement grooves are provided on all sides of the upper end of the processing seat. In the utility model, a rotating rod drives the worm to rotate, and the worm is meshed with the worm gear to drive the movable frame to move, so that the fixed plate contacts the side of the material to clamp and fix it. The pressure plate contacts the upper end of the material, and the pressure plate moves upward to drive the pressure rod to move. Under the elastic potential energy of the spring, downward pressure will be applied to the pressure plate, thereby causing the pressure plate to limit and fix the material. Under multiple fixed limits, the clamping effect of the material is increased, and the material is prevented from shifting during the processing process, affecting the processing quality.

[0004] During actual use of the above-mentioned device, since it is necessary to apply pressure to the upper end of the glass through the pressure plate to achieve fixation, when polishing and grinding the glass, the processing equipment will be unable to effectively process the area near the pressure plate. After removing the glass, workers are required to manually polish and grind the area where the pressure plate is located. In addition, since the pressure plate needs to apply pressure to the top surface of the edge of the glass to achieve fixation, it is easy to cause unnecessary stress concentration on the glass during the fixing process, increasing the risk of glass breakage. In view of this, we provide a glass limit fixing mechanism for glass grinding. Utility Model Content

[0009] As mentioned above, the outer wall of one end of the double-threaded screw is connected to one side of the outer wall of the threaded driving member, and one end of the outer wall of the double-threaded screw is rotatably connected to the internal center of the threaded driving member through a thread.

[0016] 1. According to the present invention, after the glass is placed at the center of the top surface of the lifting panel, a set of limit knobs are turned, which in turn drives the double-threaded screw fixed thereto to rotate. As the double-threaded screw rotates, the threads provided on its outer wall cooperate with the limit slide rod, gradually driving the driving thread driving member and the limit resistance members fixed on the top surface to slowly move toward the outer wall of the glass on both sides. When one set of limit resistance members contacts the outer wall of the glass, the other set of limit knobs is turned again, and the above action is repeated. By having multiple sets of limit resistance members contact the outer wall of the glass from different directions, the glass can be fixed at the center of the top surface of the lifting panel.

As the auxiliary limiting member moves, the auxiliary limiting member interferes with the inner wall of the auxiliary limiting groove, lifting the lifting panel upward, so that the height of the outer wall of the glass is higher than the height of the lifting panel where the limiting friction member extends. Therefore, after the glass is fixed by the limiting friction member, a processing blind area is avoided on the top surface of the glass. The operator can fine-tune the height of the lifting panel at any time according to the actual thickness of the glass and processing requirements, ensuring that each processing can achieve the best effect. At the same time, the stress concentration problem caused by directly applying pressure on the top surface of the glass is avoided, and the risk of glass breakage is effectively reduced.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-6As shown, the utility model provides a technical solution: a glass limit fixing mechanism for glass polishing, comprising a limit platform 1, multiple groups of corresponding limit resistance members 2 are slidably connected on both sides of the inner center of the limit platform 1, and a lifting panel 3 is slidably connected to the top of the inner top of the limit platform 1 at the same time, and multiple movable grooves 301 are provided on both sides of the top surface of the lifting panel 3, and multiple groups of corresponding limit knobs 201 are rotatably connected on both sides of the outer wall of the limit platform 1, and multiple double-threaded screw rods 202 are rotatably connected inside the limit platform 1, and the double-threaded screw rod 202 is located at the bottom center of the limit resistance member 2, the outer wall of one end of the double-threaded screw rod 202 is connected through one side of the inner wall of the limit platform 1, and the outer wall of one end of the double-threaded screw rod 202 passes through one side of the inner side of the limit platform 1 and is fixedly connected to the center of one side of the limit knob 201, multiple control knobs 302 are rotatably connected on both sides of the outer wall of the limit platform 1, and the multiple control knobs 302 are respectively located on both sides of the bottom of the lifting panel 3;

[0028] A one-way screw rod 303 is rotatably connected to the inner center of the limit platform 1, and the one-way screw rod 303 is located at the bottom center of the lifting panel 3. The outer wall of one end of the one-way screw rod 303 is connected through one side of the inner part of the limit platform 1, and the outer wall of one end of the one-way screw rod 303 is connected through one side of the inner part of the limit platform 1 and is fixedly connected to the center of one side of the regulating knob 302.

[0029] After the glass is placed at the center of the top surface of the lifting panel 3, a set of limit knobs 201 are turned, which immediately drives the double-threaded screw rod 202 fixed thereto to rotate. As the double-threaded screw rod 202 rotates, the threads on its outer wall cooperate with the limit slide 203, gradually driving the driving thread driving member 204 and the limit resistance member 2 fixed on its top surface to move slowly toward the outer wall sides of the glass. When one set of limit resistance members 2 contacts the outer wall of the glass, the other set of limit knobs 201 is turned again, and the above action is repeated. When the height of the limit resistance member 2 extending out of the lifting panel 3 is higher than the height of the outer wall of the glass, the regulating knob 302 is turned to drive the one-way screw rod 303 to rotate. The one-way screw rod 303 cooperates with the auxiliary slide rod 306 through the outer wall thread to drive the auxiliary The auxiliary driving member 305 moves along the outer wall of the auxiliary sliding rod 306, and the auxiliary limiting member 309 is driven to move by the auxiliary driving member 305. As the auxiliary limiting member 309 moves, the auxiliary limiting member 309 interferes with the inner wall of the auxiliary limiting groove 308, and lifts the lifting panel 3 upward, so that the outer wall height of the glass is higher than the height of the limiting interference member 2 extending out of the lifting panel 3, thereby avoiding a processing blind spot on the top surface of the glass after the glass is fixed by the limiting interference member 2, so that the operator can fine-tune the height of the lifting panel 3 at any time according to the actual thickness of the glass and processing requirements, ensuring that each processing can achieve the best effect. At the same time, it avoids the stress concentration problem caused by directly applying pressure to the top surface of the glass, and effectively reduces the risk of glass breakage.

[0030] like Figure 1 、 Figure 2 and Figure 5 As shown, multiple limit slides 203 are fixedly connected to the inside of the limit platform 1, and the limit slides 203 are located on both sides of the outside of the double-threaded screw rod 202. Multiple threaded driving parts 204 are slidably connected to the two sides of the inside of the limit platform 1 through the double-threaded screw rod 202 and the limit slide 203, and the multiple threaded driving parts 204 are respectively located at the two ends of the outer wall of the limit slide 203 and the double-threaded screw rod 202. The multiple limit slides 203 are staggered with each other. By placing the multiple limit slides 203 on both sides of the outside of the double-threaded screw rod 202, the limit platform 1 can drive the limit resistance part 2 to move through the limit slide 203 and the double-threaded screw rod 202.

[0031] The outer wall of one end of the double-threaded screw 202 is connected to one side of the outer wall of the threaded driving member 204, and one end of the outer wall of the double-threaded screw 202 is rotatably connected to the internal center of the threaded driving member 204 through a thread. The threaded driving member 204 is located at the lower end of the outer wall of the limiting resistance member 2, and the outer wall of the lower end of the limiting resistance member 2 is fixedly connected to the center of the top surface of the threaded driving member 204. After one end of the outer wall of the double-threaded screw 202 passes through the threaded driving member 204, the double-threaded screw 202 can rotate with the internal center of the threaded driving member 204 through the thread provided on its own outer wall, and fix the outer wall of the top end of the threaded driving member 204 to the outer wall of the bottom end of the limiting resistance member 2, so that the threaded driving member 204 can drive the limiting resistance member 2 to move.

[0032] The outer wall of one end of the limiting slide 203 passes through one side of the outer wall of the threaded driving component 204, and the inner side of the threaded driving component 204 is slidably connected to one end of the outer wall of the limiting slide 203. After the limiting slide 203 passes through the inner side of the threaded driving component 204, the movement trajectory of the threaded driving component 204 can be limited by its own outer wall.

[0033] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, auxiliary slide grooves 304 are provided on both sides of the inner wall of the limit platform 1, and the auxiliary slide grooves 304 are located on both sides of the outer wall of the lifting panel 3. One side of the outer wall of the lifting panel 3 is connected with the inner top of the auxiliary slide groove 304, and one side of the outer wall of the lifting panel 3 is slidably connected with the inner top of the auxiliary slide groove 304. After the lifting panel 3 passes through the inner top of the auxiliary slide groove 304, the auxiliary slide groove 304 limits the moving trajectory of the lifting panel 3 through its own inner wall.

[0034] One end of the outer wall of the one-way screw rod 303 is connected with an auxiliary driving part 305, and one end of the outer wall of the one-way screw rod 303 is rotatably connected to the inner side of the auxiliary driving part 305 through a thread, and the inner side of the auxiliary driving part 305 is slidably connected with an auxiliary slide bar 306, and both ends of the outer wall of the auxiliary slide bar 306 are fixedly connected to the two sides of the inner wall of the limit platform 1. The outer wall of one end of the one-way screw rod 303 is penetrated through the inner side of the auxiliary driving part 305, so that the one-way screw rod 303 can be rotatably connected to the inner side of the auxiliary driving part 305 through the outer wall thread. An auxiliary slide bar 306 is set on the outer side of the one-way screw rod 303, and the moving trajectory of the auxiliary driving part 305 can be limited by the auxiliary slide bar 306.

[0035] The lifting panel 3 has a plurality of limit panels 307 fixedly connected to the center of the bottom surface, and an auxiliary limit groove 308 is provided on one side of the outer wall of the limit panel 307. An auxiliary limit piece 309 is slidably connected to the corresponding side of the limit panel 307 through the auxiliary limit groove 308, and the outer wall of one end of the auxiliary limit piece 309 passes through the auxiliary limit groove 308 and is fixedly connected to the outer wall of one end of the auxiliary driving member 305. The plurality of limit panels 307 are fixed to the center of the bottom surface of the lifting panel 3 at the same time, and the auxiliary limit groove 308 is provided on the outer wall of the limit panel 307. This can facilitate the subsequent device to actively adjust the height of the limit panel 307 through the auxiliary limit groove 308, and fix the auxiliary driving member 305 and the auxiliary limit piece 309 to each other, so that the auxiliary driving member 305 can drive the auxiliary limit piece 309 to move horizontally along the outer wall of the auxiliary slide bar 306.

[0036] The outer wall of one end of the auxiliary limiting member 309 is connected to the inner end of the auxiliary limiting groove 308, and the outer wall of one end of the auxiliary limiting member 309 is slidably connected to the inner bottom end of the auxiliary limiting groove 308. By passing one end of the outer wall of the auxiliary limiting member 309 through the inner bottom end of the auxiliary limiting groove 308 and sliding one end of the outer wall of the auxiliary limiting member 309 with one side of the inner part of the auxiliary limiting groove 308, the auxiliary limiting member 309 can adjust the height of the lifting panel 3 through the auxiliary limiting groove 308.

[0037] Working principle: By placing multiple limit slides 203 on both sides of the double-threaded screw 202, the limit platform 1 can drive the limit resistance member 2 to move through the limit slides 203 and the double-threaded screw 202. After one end of the outer wall of the double-threaded screw 202 passes through the threaded driving member 204, the double-threaded screw 202 can rotate through the thread provided on its outer wall and the inner center of the threaded driving member 204, and align the outer wall of the top end of the threaded driving member 204 with the outer wall of the bottom end of the limit resistance member 2. The fixed connection enables the threaded drive member 204 to drive the limiting resistance member 2 to move. After the limiting slide rod 203 passes through the inner side of the threaded drive member 204, the movement trajectory of the threaded drive member 204 can be limited by its own outer wall. After the lifting panel 3 passes through the top of the auxiliary slide groove 304, the auxiliary slide groove 304 limits the movement trajectory of the lifting panel 3 through its own inner wall. The outer wall of one end of the one-way screw rod 303 passes through the inner side of the auxiliary drive member 305, so that the one-way screw rod 303 can be fixed to the inner side of the auxiliary drive member 305. The screw rod 303 can be rotatably connected to the inner side of the auxiliary driving member 305 through the outer wall thread, and an auxiliary sliding bar 306 is provided on the outer side of the one-way screw rod 303, which can limit the movement trajectory of the auxiliary driving member 305 through the auxiliary sliding bar 306, and multiple limit panels 307 are fixed at the center of the bottom surface of the lifting panel 3 at the same time, and an auxiliary limit groove 308 is opened on the outer wall of the limit panel 307, which can facilitate the subsequent device to actively adjust the height of the limit panel 307 through the auxiliary limit groove 308, and fix the auxiliary driving member 305 and the auxiliary limit member 309 to each other, so that the auxiliary driving member 305 can drive the auxiliary limit member 309 to move horizontally along the outer wall of the auxiliary sliding bar 306, by passing one end of the outer wall of the auxiliary limit member 309 through the bottom end of the auxiliary limit groove 308, and sliding one end of the outer wall of the auxiliary limit member 309 with the inner side of the auxiliary limit groove 308, so that the auxiliary limit member 309 can adjust the height of the lifting panel 3 through the auxiliary limit groove 308.
