Description

Technical Field

[0001] The present invention relates to a movable glass grinding device, belonging to the technical field of glass production. Background Art

[0002] Glass products have been widely used in lenses, prisms, mirrors, CRT displays and other components in homes, offices and factories. In the case of optical components, the surfaces of many of these glasses are used, and the optical components require their surfaces to have optical clarity and no visible defects or imperfections. If there are any, defects, imperfections and even slight scratches will affect the optical clarity of the glass products. In some cases, these defects, imperfections or slight scratches will affect the ability to observe precisely through the glass. The glass surfaces used in the case of optical components must be substantially free of any defects, imperfections or scratches. Glass grinding belongs to cold machining. It is a process of changing the shape and surface state of glass and glass products by mechanical means at normal temperature. Grinding is to process the uneven glass surface into a flat and smooth surface so as to achieve the specified shape and size. Except for a very small number of (such as bottles and cans) of the formed glass products that can directly meet the requirements, most of them need to be processed to reach the required products. Before some flat glass is processed, the original glass sheet also needs to be processed. Grinding can improve the appearance and surface quality of glass and can also be used for decoration.

[0003] The prior art has the following technical defects:

[0004] At present, in the process of optoelectronic glass production, some glass products need to be ground. In actual production, manual grinding is usually used. Abrasive cloth or fine sandpaper is often used for grinding during manual grinding. The surface of the cover plate is easily contaminated during the grinding process, reducing the production efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a movable glass grinding device.

[0006] The movable glass grinding device described in the present invention includes a bearing plate, on which a control system, a centering chuck and a column are provided. A telescopic arm is slidably connected to the column. A lifting mechanism and a spindle lifting mechanism are provided on the telescopic arm. A spindle driving mechanism is provided at one end of the telescopic arm. The spindle driving mechanism is connected to a spindle. A return spring is provided on the spindle. A spindle lever is fixedly connected to the spindle below the return spring. The spindle lever is connected to the spindle lifting mechanism. A grinding tool is connected to the bottom end of the spindle. The grinding tool is coaxially matched with the centering chuck. Both the spindle lifting mechanism and the spindle driving mechanism are connected to the control system.

[0007] Working Process or Principle:

[0008] During operation, the operator places the glass in the centering chuck and clamps it. Then, the lifting mechanism is used to control the telescopic arm to drive the spindle downward until the grinding tool reaches the appropriate position and stops. Next, the control system is used to control the spindle drive mechanism to start working. The spindle drive mechanism drives the spindle to rotate, which in turn drives the grinding tool to start working. At the same time, the control system controls the spindle lifting mechanism to work. The spindle lifting mechanism drives the spindle to perform a short axial movement through the spindle lever to avoid the occurrence of deep groove wear. When the grinding is completed, the lifting mechanism is lifted to remove the glass, completing the grinding process. By using equipment instead of manual labor, not only can the grinding accuracy be guaranteed, but also the glass will not be contaminated, improving the processing efficiency.

[0009] The lifting mechanism described above includes a handwheel support plate at the top of the column. A lifting handwheel is rotatably connected to the handwheel support plate. The lifting handwheel is connected to a lead screw, and the lead screw passes through the telescopic arm and is threadedly connected thereto. The operator rotates the lifting handwheel to drive the lead screw to rotate, thereby causing the telescopic arm threadedly connected to the lead screw to move up and down, and further realizing the lifting of the spindle connected thereto.

[0010] The spindle lifting mechanism described above includes an upper fixing plate fixed to the telescopic arm. The upper fixing plate is connected to a lower fixing plate through a screw and nut. Pulleys are provided on both the upper fixing plate and the lower fixing plate. A traction electromagnet is provided on the lower fixing plate. A traction cable is connected to the traction electromagnet. The traction cable passes through the pulley and is connected to the spindle lever. The traction electromagnet is connected to the control system. The control system is used to control the traction electromagnet to automatically attract. When the traction electromagnet attracts, the traction electromagnet drives the traction cable downward. The traction cable drives the spindle lever downward through the pulley, and then drives the spindle downward. When the traction electromagnet is powered off, the return spring on the spindle resets the spindle, thereby realizing the short axial movement of the spindle. By the short axial movement of the spindle, the situation where a spindle without axial movement generates a series of deep grooves on the grinding surface every 3-5 revolutions during grinding is eliminated, avoiding the occurrence of wear.

[0011] A traction cable adjusting frame is also provided on the traction cable. The length of the traction cable is finely adjusted using the traction cable adjusting frame according to the actual processing situation to achieve the best length ratio.

[0012] The spindle drive mechanism described above includes a spindle box fixed to the telescopic arm. A speed regulating motor is connected to the spindle box. The speed regulating motor is connected to a reducer, and the reducer is connected to the spindle. The speed regulating motor is connected to the control system. The control system is used to control the forward and reverse rotation and working time of the speed regulating motor, thereby realizing the commutation of the spindle and the control of the grinding time.

[0013] A universal coupling is connected between the main shaft and the speed reducer. To eliminate the possible deviation of the small coaxiality between the main shaft and the glass to be ground, when there is an axis angle, the universal coupling can also realize the continuous rotation of the two connected shafts and reliably transmit torque and motion.

[0014] A handle is provided on the main shaft box, which is convenient for supporting during disassembly.

[0015] A sleeve is provided on the bearing plate, and the column is rotatably connected in the sleeve. The column can rotate within the sleeve by 0° to 60°. When clamping and placing the glass to be ground, push the handle on the main shaft box to rotate the column, so that the position of the main shaft and the centering chuck is separated, facilitating the staff to place and take the glass.

[0016] A number of universal wheels and a push rod are provided on the bearing plate. Through the push rod and the universal wheels, the equipment can be moved to a position convenient for glass grinding processing for grinding, eliminating the step of transferring the glass to the grinding equipment area for processing, reducing the number of movements of the glass processing, reducing the damage caused by transfer, and improving the efficiency of glass production.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By using the equipment of the present invention to replace manual grinding processing, and automatically adjusting the grinding direction and processing time through the control system, it can ensure the grinding effect without polluting the glass, and improve the processing efficiency.

The spindle 12 lifting mechanism and the spindle 12 driving mechanism are both connected to the control system 14.

[0027] Working process or working principle:

[0028] During work, the staff places the workpiece 17 in the centering chuck 16 and clamps it, and then controls the arm 5 through the lifting mechanism to drive the spindle 12 down, so that the grinding tool 18 stops after reaching the appropriate position, and then controls the spindle 12 driving mechanism through the control system 14 to start working. The spindle 12 driving mechanism drives the spindle 12 to rotate, and then drives the grinding tool 18 to start working. At the same time, the control system 14 controls the spindle 12 lifting mechanism to work, and the spindle 12 lifting mechanism drives the spindle 12 to perform a short axial movement through the spindle lever 11 to avoid deep groove grinding. When the grinding is completed, lift the lifting mechanism to take out the workpiece 17 to complete the grinding process. By replacing manual labor with equipment, the grinding accuracy can be guaranteed without contaminating the workpiece 17, thereby improving processing efficiency.

[0029] The present invention utilizes equipment to replace manual grinding, and the control system 14 automatically adjusts the grinding direction and processing time, thereby ensuring that the grinding is thorough without contaminating the glass, thereby improving processing efficiency.

[0030] Example 2

[0031] As Figures 1 to 5 shown, the movable glass grinding equipment of the present invention includes a carrier plate 13, on which a control system 14, a centering chuck 16 and a column 26 are provided. A telescopic arm 5 is slidably connected to the column 26. An elevating mechanism and a spindle 12 lifting mechanism are provided on the telescopic arm 5. A spindle 12 driving mechanism is provided at one end of the telescopic arm 5. The spindle 12 driving mechanism is connected to a spindle 12. A return spring 10 is provided on the spindle 12. A spindle lever 11 is fixedly connected to the spindle 12 below the return spring 10. The spindle lever 11 is connected to the spindle 12 lifting mechanism. The bottom end of the spindle 12 is connected to a grinding tool 18. The grinding tool 18 is coaxially matched with the centering chuck 16. Both the spindle 12 lifting mechanism and the spindle 12 driving mechanism are connected to the control system 14.

[0032] In this embodiment: The lifting mechanism includes a handwheel support plate 2 at the top of the column 26. A lifting handwheel 3 is rotatably connected to the handwheel support plate 2. The lifting handwheel 3 is connected to a lead screw 4. The lead screw 4 passes through and is threadedly connected to the telescopic arm 5. The operator rotates the lifting handwheel 3 to drive the lead screw 4 to rotate, so as to realize the up and down movement of the telescopic arm 5 threadedly connected to the lead screw 4, and further realize the lifting of the main shaft 12 connected thereto; The lifting mechanism of the main shaft 12 includes an upper fixing plate 25 fixed on the telescopic arm 5. The upper fixing plate 25 is connected to a lower fixing plate 20 through a screw and nut. Pulley 21 is provided on both the upper fixing plate 25 and the lower fixing plate 20. A traction electromagnet 22 is provided on the lower fixing plate 20. A traction cable 24 is connected to the traction electromagnet 22. The traction cable 24 passes through the pulley 21 and is connected to the main shaft lever 11. The traction electromagnet 22 is connected to the control system 14. The traction electromagnet 22 is controlled by the control system 14 to automatically attract. After the traction electromagnet 22 attracts, the traction electromagnet 22 drives the traction cable 24 downward. The traction cable 24 drives the main shaft lever 11 to move downward through the pulley 21, and then drives the main shaft 12 to move downward. When the traction electromagnet 22 is powered off, the return spring 10 on the main shaft 12 resets the main shaft 12, so as to realize the short axial movement of the main shaft 12. Through the short axial movement of the main shaft 12, the situation that a deep groove will be generated on the grinding surface every 3-5 revolutions of the main shaft 12 without axial movement during grinding is eliminated, and the situation of grinding damage is avoided; A traction cable adjusting frame 23 is also provided on the traction cable 24. The length of the traction cable 24 is finely adjusted by using the traction cable adjusting frame 23 according to the actual processing situation to achieve the best length ratio; The driving mechanism of the main shaft 12 includes a main shaft box 8 fixed on the telescopic arm 5. A speed regulating motor 6 is connected to the main shaft box 8. The speed regulating motor 6 is connected to a reducer 27. The reducer 27 is connected to the main shaft 12.

The forward and reverse rotation and working time of the speed regulating motor 6 are controlled by the control system 14, so as to realize the commutation of the main shaft 12 and the control of the grinding time; A universal coupling 9 is connected between the main shaft 12 and the reducer 27. To eliminate the possible small coaxiality deviation between the main shaft 12 and the glass to be ground, when there is an axis angle, the universal coupling 9 can also realize the continuous rotation of the two connected shafts and reliably transmit torque and motion; A grip 7 is provided on the main shaft box 8, which is convenient for supporting during disassembly; A sleeve 19 is provided on the bearing plate 13. The column 26 is rotatably connected in the sleeve 19. The column 26 can rotate within the sleeve 19 by 0° to 60°. When clamping and placing the glass to be ground, the grip 7 on the main shaft box 8 is pushed to rotate the column 26, so that the position of the main shaft 12 is separated from the centering chuck 16, which is convenient for the operator to place and take the glass;A plurality of universal wheels 15 and a push rod 1 are provided on the bearing plate 13. Through the push rod 1 and the universal wheels 15, the device can be moved to a position convenient for glass grinding processing for grinding, eliminating the step of transferring the glass to the grinding equipment area for processing, reducing the number of movements of glass processing, reducing the damage caused by transfer, and improving the efficiency of glass production.

[0033] Working process or working principle:

[0034] During operation, the worker places the workpiece 17 in the centering chuck 16 and clamps it. Then, the worker rotates the lifting handwheel 3 to drive the lead screw 4 to rotate, thereby realizing the up and down movement of the telescopic arm 5 threadedly connected to the lead screw 4, and further realizing the lifting of the main shaft 12 connected thereto. After the grinding tool 18 reaches the appropriate position, it stops. Then, the control system 14 controls the forward and reverse rotation and working time of the speed regulating motor 6, thereby realizing the commutation of the main shaft 12 and the control of the grinding time. The speed regulating motor 6 drives the main shaft 12 to rotate, and then drives the grinding tool 18 to start working. At the same time, the control system 14 controls the traction electromagnet 22 to automatically attract. When the traction electromagnet 22 attracts, the traction electromagnet 22 drives the traction cable 24 downward. The traction cable 24 drives the main shaft lever 11 downward through the pulley 21, and then drives the main shaft 12 downward. When the traction electromagnet 22 is powered off, the return spring 10 on the main shaft 12 resets the main shaft 12, thereby realizing the short axial movement of the main shaft 12. Through the short axial movement of the main shaft 12, the situation that the main shaft 12 without axial movement generates a series of deep grooves on the grinding surface every 3 - 5 revolutions during grinding is eliminated. When the grinding is completed, the lifting handwheel 3 is rotated to lift the telescopic arm 5 and the workpiece 17 is taken out to complete the grinding process. Using the device instead of manual labor can not only ensure the grinding accuracy but also prevent the workpiece 17 from being contaminated, improving the processing efficiency.

[0035] Through the present invention, using the device to replace manual grinding processing and automatically adjusting the grinding direction and processing time through the control system 14 can ensure the grinding effect while preventing the glass from being contaminated, improving the processing efficiency.
