Description

Technical Field

[0001] This invention belongs to the technical field of diamond grinding machines, and specifically relates to a diamond grinding machine with omnidirectional grinding function and its usage method. Background Technology

[0002] Diamond is a mineral composed of carbon, an allotrope of graphite, and the precursor to the common diamond. It is the hardest naturally occurring substance in nature. Graphite can be transformed into synthetic diamonds under high temperature and pressure. Diamonds have a wide range of applications. Grinding machines are machine tools that use abrasive wheels to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels, while a few use oilstones, abrasive belts, or other abrasive tools and free abrasives.

[0003] In existing technologies, diamond grinding machines typically require constant changes in clamping position during grinding to ensure that every side of the diamond can be ground. Without moving the position, it is difficult to grind the area where the diamond is clamped, reducing the ease of use of the diamond grinding machine and easily causing grinding deviations. Therefore, there is a need for a diamond grinding machine with omnidirectional grinding capabilities.

[0004] Therefore, it is necessary to invent a diamond grinding machine with all-around grinding function and its usage method to solve the above problems. It can grind any part of the diamond and improve the grinding efficiency of the diamond. Summary of the Invention

The first motor, the second motor, the third motor, the fourth motor and the fifth motor are electrically connected to an external power supply through the first motor switch, the second motor switch, the third motor switch, the fourth motor switch and the fifth motor switch respectively.

[0016] A method for using a diamond grinding machine with omnidirectional grinding capabilities is as follows:

[0017] Step 1: The staff places the diamond to be polished in the middle of the first positioning frame and the second positioning frame, turns on the first motor switch, so that the first motor fixed at the top of the first positioning frame and the second positioning frame drives the two third positioning screws to rotate, so that the two third positioning screws drive the four lifting frames to move in opposite directions, so that the two positioning seats and the two positioning discs are in contact with the outer wall of the diamond.

[0018] Step 2: When it is necessary to adjust the diamond angle, the positioning plate fixed on one side of the first positioning frame is separated from the diamond by controlling one of the first motors. The first positioning screw is rotated by one of the external drive mechanisms, which in turn moves the first positioning frame so that the two positioning plates are moved to the appropriate position. The two positioning plates clamp the diamond by controlling the first motor, and the two positioning seats are separated from the diamond by controlling the other first motor.

[0019] Step 3: Turn on the second motor switch so that the output end of the second motor fixed at the top of the limit frame drives the second positioning gear to rotate. Through the meshing of the second positioning gear and the first positioning gear, the first positioning gear passes through one of the lifting frames and drives one of the positioning discs to rotate. Through the rotation of the two positioning discs and the protection of the anti-slip pad, the diamond rotates stably.

[0020] Step 4: When it is necessary to polish the top and bottom sides of the diamond, the first positioning screw and the second positioning screw are rotated by controlling the drive mechanism in sequence. This causes the first positioning frame and the second positioning frame to drive the two positioning seats and the two positioning disks to move respectively, so that the diamond can be positioned by clamping the leftmost and rightmost ends, and so that each area of ​​the diamond can be polished in place during polishing.

[0021] Step 5: Turn on the third motor switch so that the third motor fixed at the top of the support frame drives the limit screw to rotate, so that the adjustment frame moves up and down along the support frame through the positioning of the fixed groove. Turn on the fourth motor switch so that the output end of the fourth motor fixed on one side of the rotating frame drives the grinding wheel to rotate and grind.

[0022] Step Six: Turn on the fifth motor switch, so that the output end of the fifth motor fixed on one side of the adjustment frame drives the positioning shaft to rotate, so that the fixed gear fixed on the outer wall of the positioning shaft meshes with the positioning gear ring fixed on one side of the rotating frame, so that the positioning gear ring drives the rotating frame to rotate along one end of the adjustment frame. Through the cooperative control of the grinding lifting mechanism, the grinding wheel rotates at different angles, which is convenient for grinding the top, bottom and different surfaces of the diamond.

[0023] The technical effects and advantages of this invention are as follows:

[0024] 1. The present invention controls the drive mechanism to rotate the first positioning screw and the second positioning screw in sequence, so that the first positioning frame and the second positioning frame drive the two positioning seats and the two positioning disks to move respectively, so that the diamond can be positioned by clamping the leftmost and rightmost ends, so that each area of ​​the diamond can be ground in place during grinding, increasing the ease of use of the diamond grinding machine and improving the accuracy of diamond processing.

[0025] 2. The present invention uses one of the first motors to control the positioning disk fixed on one side of the first positioning frame to separate from the diamond. One of the external drive mechanisms drives the first positioning screw to rotate, which in turn drives the first positioning frame to move, so that the two positioning disks are moved to the appropriate position. By controlling the first motor, the two positioning disks clamp the diamond. By controlling the other first motor, both positioning seats are separated from the diamond.

[0026] 3. In this invention, the output end of the fifth motor fixed on one side of the adjustment frame drives the positioning shaft to rotate, so that the fixed gear fixed on the outer wall of the positioning shaft meshes with the positioning gear ring fixed on one side of the rotating frame. This causes the positioning gear ring to drive the rotating frame to rotate along one end of the adjustment frame. Through the cooperative control of the grinding lifting mechanism, the grinding wheel can rotate at different angles, which is convenient for grinding the top, bottom and different surfaces of the diamond, and facilitates all-round grinding of the diamond.

[0048] A method for using a diamond grinding machine with omnidirectional grinding capabilities is as follows:

[0049] Step 1: The worker places the diamond to be polished in the middle of the first positioning frame 502 and the second positioning frame 503, turns on the first motor switch, and causes the first motor 511 fixed at the top of the first positioning frame 502 and the second positioning frame 503 to drive the two third positioning screws 509 to rotate, so that the two third positioning screws 509 drive the four lifting frames 510 to move in opposite directions, so that the two positioning seats 508 and the two positioning discs 512 are in contact with the outer wall of the diamond.

[0050] Step 2: When it is necessary to adjust the diamond angle, the positioning plate 512 fixed on one side of the first positioning frame 502 is separated from the diamond by controlling one of the first motors 511. The first positioning screw 504 is rotated by one of the external drive mechanisms, which in turn moves the first positioning frame 502, so that the two positioning plates 512 are moved to the appropriate position. The two positioning plates 512 are clamped by controlling the first motor 511, and the two positioning seats 508 are separated from the diamond by controlling the other first motor 511.

[0051] Step 3: Turn on the second motor switch so that the output end of the second motor 517 fixed at the top of the limit frame 514 drives the second positioning gear 515 to rotate. Through the meshing of the second positioning gear 515 and the first positioning gear 516, the first positioning gear 516 passes through one of the lifting frames 510 and drives one of the positioning disks 512 to rotate. Through the rotation of the two positioning disks 512 and the protection of the anti-slip pads 513, the diamond is rotated stably.

[0052] Step 4: When it is necessary to polish the top and bottom sides of the diamond, the first positioning screw 504 and the second positioning screw 505 are rotated by controlling the drive mechanism in sequence. This causes the first positioning frame 502 and the second positioning frame 503 to drive the two positioning seats 508 and the two positioning disks 512 to move respectively, so that the diamond can be positioned by clamping the leftmost and rightmost ends, and so that each area of ​​the diamond can be polished in place during polishing.

[0053] Step 5: Turn on the third motor switch so that the third motor 603 fixed at the top of the support frame 601 drives the limit screw 602 to rotate, so that the adjusting frame 701 moves up and down along the support frame 601 through the positioning of the fixing groove 604. Turn on the fourth motor switch so that the output end of the fourth motor 704 fixed on one side of the rotating frame 702 drives the grinding wheel 708 to rotate and grind.

[0054] Step Six: Turn on the fifth motor switch, so that the output end of the fifth motor 707 fixed on one side of the adjustment frame 701 drives the positioning shaft 705 to rotate, so that the fixed gear 706 fixed on the outer wall of the positioning shaft 705 meshes with the positioning gear ring 703 fixed on one side of the rotating frame 702, so that the positioning gear ring 703 drives the rotating frame 702 to rotate along one end of the adjustment frame 701. Through the cooperative control of the grinding lifting mechanism, the grinding wheel 708 rotates at different angles, which is convenient for grinding the top, bottom and different surfaces of the diamond.

[0055] Working principle: When diamonds need to be polished, such as... Figures 1-4As shown, the worker places the diamond to be polished in the middle of the first positioning frame 502 and the second positioning frame 503, turns on the first motor switch, and causes the first motor 511 fixed at the top of the first positioning frame 502 and the second positioning frame 503 to drive the two third positioning screws 509 to rotate, so that the two third positioning screws 509 drive the four lifting frames 510 to move in opposite directions, so that the two positioning seats 508 and the two positioning discs 512 are in contact with the outer wall of the diamond.

[0056] When the diamond angle needs to be adjusted, the positioning disk 512 fixed on one side of the first positioning frame 502 is separated from the diamond by controlling one of the first motors 511. The first positioning screw 504 is rotated by one of the external drive mechanisms, which in turn moves the first positioning frame 502, so that the two positioning disks 512 are moved to the appropriate position. The two positioning disks 512 clamp the diamond by controlling the first motor 511, and the two positioning seats 508 are separated from the diamond by controlling the other first motor 511.

[0057] Turning on the second motor switch causes the output end of the second motor 517, which is fixed at the top of the limit frame 514, to drive the second positioning gear 515 to rotate. Through the meshing of the second positioning gear 515 and the first positioning gear 516, the first positioning gear 516 passes through one of the lifting frames 510 and drives one of the positioning discs 512 to rotate. Through the rotation of the two positioning discs 512 and the protection of the anti-slip pad 513, the diamond is able to rotate stably.

[0058] When it is necessary to grind the top and bottom sides of the diamond, the first positioning screw 504 and the second positioning screw 505 are rotated by controlling the drive mechanism in sequence. This causes the first positioning frame 502 and the second positioning frame 503 to drive the two positioning seats 508 and the two positioning disks 512 to move respectively. This makes it easier to position the diamond by clamping the leftmost and rightmost ends. This ensures that each area of ​​the diamond can be ground properly during grinding, increasing the ease of use of the diamond grinding machine and improving the accuracy of diamond processing.

[0059] like Figures 5-6 As shown, when the third motor switch is turned on, the third motor 603 fixed at the top of the support frame 601 drives the limit screw 602 to rotate, so that the adjustment frame 701 moves up and down along the support frame 601 through the positioning of the fixing groove 604. When the fourth motor switch is turned on, the output end of the fourth motor 704 fixed on one side of the rotating frame 702 drives the grinding wheel 708 to rotate and grind.

[0060] Turning on the fifth motor switch causes the output end of the fifth motor 707, which is fixed to one side of the adjustment frame 701, to drive the positioning shaft 705 to rotate. This causes the fixed gear 706, which is fixed to the outer wall of the positioning shaft 705, to mesh with the positioning gear ring 703, which is fixed to one side of the rotating frame 702. The positioning gear ring 703 then drives the rotating frame 702 to rotate along one end of the adjustment frame 701. Through the coordinated control of the grinding lifting mechanism, the grinding wheel 708 can rotate at different angles, making it convenient to grind the top, bottom, and different surfaces of the diamond, thus facilitating all-round grinding of the diamond.

8. The method of using a diamond grinding machine with omnidirectional grinding function according to claim 7 is as follows: Step 1: The staff places the diamond to be polished in the middle of the first positioning frame (502) and the second positioning frame (503), turns on the first motor switch, so that the first motor (511) fixed at the top of the first positioning frame (502) and the second positioning frame (503) drives the two third positioning screws (509) to rotate, so that the two third positioning screws (509) drive the four lifting frames (510) to move towards each other, so that the two positioning seats (508) and the two positioning discs (512) are in contact with the outer wall of the diamond. Step 2: When it is necessary to adjust the diamond angle, the positioning plate (512) fixed on one side of the first positioning frame (502) is separated from the diamond by controlling one of the first motors (511). The first positioning screw (504) is rotated by one of the external drive mechanisms, so that the first positioning screw (504) drives the first positioning frame (502) to move, so that the two positioning plates (512) are moved to the appropriate position. By controlling the first motor (511), the two positioning plates (512) clamp the diamond. By controlling the other first motor (511), both positioning seats (508) are separated from the diamond. Step 3: Turn on the second motor switch so that the output end of the second motor (517) fixed at the top of the limit frame (514) drives the second positioning gear (515) to rotate. Through the meshing of the second positioning gear (515) and the first positioning gear (516), the first positioning gear (516) passes through one of the lifting frames (510) and drives one of the positioning discs (512) to rotate. Through the rotation of the two positioning discs (512) and the protection of the anti-slip pad (513), the diamond is rotated stably. Step 4: When it is necessary to polish the top and bottom sides of the diamond, the first positioning screw (504) and the second positioning screw (505) are rotated by controlling the drive mechanism in sequence, so that the first positioning frame (502) and the second positioning frame (503) drive the two positioning seats (508) and the two positioning disks (512) to move respectively, so that the diamond can be easily positioned by clamping the leftmost and rightmost ends, so that each area of ​​the diamond can be polished in place during polishing; Step 5: Turn on the third motor switch so that the third motor (603) fixed at the top of the support frame (601) drives the limit screw (602) to rotate, so that the adjusting frame (701) moves up and down along the support frame (601) through the positioning of the fixing groove (604). Turn on the fourth motor switch so that the output end of the fourth motor (704) fixed on one side of the rotating frame (702) drives the grinding wheel (708) to rotate and grind. Step 6: Turn on the fifth motor switch so that the output end of the fifth motor (707) fixed on one side of the adjustment frame (701) drives the positioning shaft (705) to rotate. This causes the fixed gear (706) fixed on the outer wall of the positioning shaft (705) to mesh with the positioning gear ring (703) fixed on one side of the rotating frame (702). This causes the positioning gear ring (703) to drive the rotating frame (702) to rotate along one end of the adjustment frame (701). Through the cooperative control of the grinding lifting mechanism, the grinding wheel (708) rotates at different angles, which is convenient for grinding the top, bottom and different surfaces of the diamond.
