Description

Technical Field

[0001] The utility model relates to the technical field of organic glass polishing, in particular to a clamping mechanism of an organic glass edge polishing machine. Background Art

[0002] Organic glass is a popular name. The chemical name of this polymer transparent material is polymethyl methacrylate, which is a polymer compound formed by the polymerization of methyl methacrylate. It is an important thermoplastic plastic that was developed earlier. When processing and using organic glass, in order to further process the burrs on the edges of the organic glass after slitting, the corresponding polishing machine will be used to grind the edges of the organic glass. In order to improve the polishing stability of the edges of the organic glass, the corresponding clamping mechanism will be used to clamp the organic glass, which is convenient for grinding and polishing the edges of the organic glass.

[0003] According to the public patent CN207239865U, a plexiglass edge polishing machine includes a base, vertical support rods fixed on both sides of the base, and a horizontal support beam connecting the top ends of the two vertical support rods. A support column is fixed in the center of the base, and the middle part of the support column is connected to a support plate with a second gear on the bottom surface through a bearing, and the second gear is meshed with the first gear nested on the first motor rotor; a lower clamp is connected to the top of the support column, and the lower clamp corresponds to the upper clamp at the end of the second motor rotor fixed on the horizontal support beam; an elongated slide groove is formed on both sides of the through hole formed in the center of the support plate along the extension direction of the support plate, and a third motor base and a fourth motor base are respectively provided in the two slide grooves; a third motor is fixed on the third motor base, and the rotor of the third motor is connected to the grinding head; a fourth motor is fixed on the fourth motor base at a certain angle, and the rotor of the fourth motor is connected to the grinding head. The present invention has a high degree of automation and broad application prospects. In the process of realizing the present invention, the inventors found that at least the following problems existed in the prior art and were not solved. The problem of insufficient stability of the organic glass edge during grinding and polishing was solved by providing corresponding upper and lower clamps to clamp and fix the organic glass surface. However, in actual use, when the upper and lower clamps are used to adhere to the organic glass surface for clamping and fixing, the contact positions of the upper and lower clamp surfaces and the organic glass cannot be adjusted for suitability. As a result, when clamping organic glasses of different specifications, it is very easy to cause obstruction to the organic glass edge due to the small fixed position range or when clamping the organic glass, thereby affecting the clamping stability of the organic glass and making it impossible to quickly grind and polish the organic glass edge. Therefore, it is necessary to design a new technical solution to solve this problem. Utility Model Content

[0025] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A clamping mechanism for an organic glass edge polishing machine, see Figures 1 to 4A cushioning pad 12 is fixedly bonded to the top surface of the operating table 1, and a support frame 11 is fixedly installed on the top surface of the operating table 1. A hollow tube 2 is movably installed at the middle part of the top inner side of the support frame 11, and a driving mechanism is provided inside the hollow tube 2. A guide tube 21 is provided at the bottom outer side of the hollow tube 2, and the number of the guide tubes 21 is four groups, and a movable rod 22 is slidably inserted through the inside of each guide tube 21. The movable rod 22 and the driving mechanism are connected by a transmission mechanism, and an adsorption mechanism is provided on the side of each movable rod 22. Through the interaction of the driving mechanism and the transmission mechanism, multiple groups of adsorption mechanisms can be driven to move horizontally synchronously, and the adsorption clamping position of the adsorption mechanism can be adjusted. While improving the applicability of the overall clamping adsorption mechanism, the clamping stability of the organic glass is simultaneously improved to avoid blocking the edge of the organic glass and affecting the grinding and polishing quality.

[0027] For details, see Figures 1 to 4 The driving mechanism includes a rotating screw 23, and a rotating screw 23 is installed vertically in the hollow tube 2 through a bearing. The outer top of each rotating screw 23 is movably sleeved with a lifting sleeve 24, and the outer surface of each lifting sleeve 24 is fixedly installed with a transmission block 25. A limited sliding groove 51 is provided inside the outer side of the hollow tube 2, and the transmission block 25 is slidably inserted into the inner side of the limiting sliding groove 51. The outer top of the hollow tube 2 is slidably sleeved with a sliding frame 26, and the side edge of the transmission block 25 is fixedly connected to the inner side wall of the sliding frame 26. A servo motor 4 is fixedly installed on the top surface of the inner side of the hollow tube 2, and the bottom of the servo motor 4 transmission shaft is fixedly connected to the top surface of the rotating screw 23 through a coupling. Under the rotation transmission action of the rotating screw 23 on the lifting sleeve 24, when the rotating screw 23 is driven to rotate, the lifting sleeve 24 can only move vertically inside the hollow tube 2 and will not rotate axially.

[0028] For further information, see Figures 1 to 4 The transmission mechanism includes a transmission rod 17, and a sliding sleeve 29 is slidably connected to the outer end of each guide tube 21 close to the hollow tube 2. A connecting frame is fixedly installed on the outer surface of each sliding frame 26 and the sliding sleeve 29. The sides of each two groups of the connecting frames are hinged to the two ends of the side of the transmission rod 17 through a rotating shaft. Under the transmission connection of the transmission rod 17, the vertical movement force of the sliding frame 26 can be converted into a horizontal driving force for the sliding sleeve 29, thereby adjusting the horizontal position of the fixed suction cup 18.

[0029] It is worth noting that, see Figures 1 to 4A push plate 27 is fixedly installed on the side of each movable rod 22, and the push plate 27 is slidably installed inside the hollow tube 2. A connecting block 28 is fixedly installed on the outer end surfaces of each push plate 27, and the side of the connecting block 28 is fixedly connected to the inner wall of the sliding sleeve 29. A guide groove 5 is opened on both sides of the outside of each guide tube 21, and the connecting block 28 is slidably inserted into the inside of the guide groove 5. Under the guiding sliding action of the guide groove 5 on the connecting block 28, when the transmission rod 17 pushes the sliding sleeve 29, the sliding sleeve 29 can move horizontally inside and outside the guide tube 21 synchronously with the push plate 27 and the movable rod 22.

[0030] It is worth noting that see Figures 1 to 4 The adsorption mechanism includes a fixed suction cup 18 and a bellows 14. A fixed plate 16 is fixedly installed at one end of each movable rod 22 away from the hollow tube 2. A connecting tube 13 is vertically penetrated and fixedly installed at the middle end of each fixed plate 16. The bottom of each connecting tube 13 is fixedly connected to a fixed suction cup 18, and the top of each connecting tube 13 is fixedly connected to a bellows 14. The top of each bellows 14 is fixedly connected to a fixed tube 15. The fixed suction cup 18 and the external vacuum pump are connected through the bellows 14, so that when the position of the fixed suction cup 18 is moved, the connection between the fixed suction cup 18 and the external vacuum pump can be maintained.

[0031] It is worth mentioning that see Figures 1 to 4 The top surface of the support frame 11 is vertically fixed with electric push rods 3, and the top surface of the transmission shaft of each electric push rod 3 is fixedly installed with a lifting plate 31. A connecting plate 32 is fixedly installed between the sides of the two groups of lifting plates 31. A fixing rod 33 is vertically fixedly installed at the middle end of the bottom of the connecting plate 32, and the bottom of the fixing rod 33 is fixedly connected to the top of the outer side of the hollow tube 2. A movable groove 34 is provided at the middle end of the top of the support frame 11, and the fixing rod 33 is slidably inserted into the inside of the movable groove 34. Through the structural action of the electric push rod 3, a vertical movement driving force can be provided to the hollow tube 2 and the fixed suction cup 18, so that the adsorption height position of the fixed suction cup 18 can be adjusted while the organic glass adsorbed by the fixed suction cup 18 can be vertically driven, which is convenient for edge polishing of the organic glass.

[0032] During operation, after the organic glass with the required edge polishing is placed on the surface of the cushion pad 12 on the surface of the operating table 1, the servo motor 4 is turned on through the external control switch to make it run and drive the rotating screw 23 to rotate synchronously inside the hollow tube 2. Combined with the limiting sliding action of the limiting slide 51 on the transmission block 25, the lifting sleeve 24 can move vertically inside the hollow tube 2. Synchronously, under the connecting transmission action of the transmission block 25, the sliding frame 26 located on the outside of the hollow tube 2 can be driven to move along with the vertical movement of the lifting sleeve 24. The driving is carried out synchronously, and then, combined with the transmission conversion effect of the transmission rod 17, the vertical movement force of the sliding frame 26 can be converted into a horizontal driving force for the sliding sleeve 29, so that the sliding sleeve 29 can drive the pushing plate 27 and the movable rod 22 to move relatively synchronously inside the guide tube 21 under the transmission connection effect of the connecting block 28, so that the movable rod 22 can drive the fixing plate 16 and the fixed suction cup 18 on its side to move horizontally relative to each other on the outside of the bottom of the hollow tube 2 until the fixed suction cup 18 moves close to the polished organic After the four corners of the glass edge are smooth, the electric push rod 3 is turned on by the external control switch, and it is operated to drive the hollow tube 2 and the fixed suction cup 18 at the bottom thereof to descend vertically synchronously, so that the fixed suction cup 18 can be attached to the outer wall of the organic glass. After that, the external vacuum pump is started, and the fixed suction cup 18 is connected to the outer wall of the organic glass by the extension and communication of the bellows 14. The fixed suction cup 18 is pushed and adjusted in position, so that the fixed suction cup 18 is still connected to the vacuum pump and the fixed suction cup 18 under the communication effect of the bellows 14. The external vacuum pump is started to make the fixed suction cup 18 It generates negative pressure suction inside the bellows 14 and the fixed suction cup 18, so that the fixed suction cup 18 can be stably adsorbed and adhered to the outer wall of the organic glass, and the organic glass is adsorbed, clamped and fixed. Then the electric push rod 3 is started to operate and drive the organic glass to be lifted synchronously and moved away from the surface of the operating table 1. Then, the corresponding grinder and polisher is used to grind and polish the edge of the organic glass. Under the vacuum adsorption action of the fixed suction cup 18, it is ensured that during the grinding and polishing process, the organic glass will not move arbitrarily and affect the grinding and polishing quality.
