[0023] Embodiment: A double-sided precision machining grinder, as Figures 1-3As shown in the figure, it includes a support frame 1, a first fixing frame 2, a first fixing block 3, a first motor 4, a first bidirectional screw 5, a guide block 6, a second fixing frame 7, a second motor 8, a grinding wheel 9, a controller 10, a servo motor 11, a unidirectional screw 1101, a slider 12 and a magnetic adsorption table 13.

A magnetic adsorption table 13 is fixedly connected to the top of the slider 12. The switch of the magnetic adsorption table is located in the middle of the front side. The spray head 19 is located above the magnetic adsorption table 13, so that the coolant sprayed out can more easily cool the workpiece.

[0024] As Figure 4 and Figure 5 shown in the figure, it further includes a second fixing block 14, a water tank 15, a water inlet pipe 16, an airbag 17, a water outlet pipe 18, a spray head 19, a pressing rod 20, a fixing ring 21 and an elastic member 22. A second fixing block 14 is fixedly connected to the rear part of the first fixing block 3. A water tank 15 is fixedly connected to the right part of the upper side of the second fixing block 14. The bottom of the water tank 15 is connected and communicated with a water inlet pipe 16. The top of the water inlet pipe 16 is provided with a top cover, which can prevent impurities from entering the water inlet pipe 16 when the coolant does not need to be refilled. The left end of the water inlet pipe 16 is connected and communicated with an airbag 17. The bottom of the airbag 17 is connected and communicated with a water outlet pipe 18. The shape of the water outlet pipe is inclined with both sides biased inward. Spray heads 19 are symmetrically connected to the water outlet pipe 18 on the left and right. A pressing rod 20 is slidably inserted through the right side of the second fixing block 14. The left part of the pressing rod 20 is slidably inserted through a fixing ring 21, and the fixing ring 21 is fixedly connected to the second fixing block 14. An elastic member 22 is provided between the pressing rod 20 and the fixing ring 21, and the elastic member 22 is wound around the pressing rod 20.

[0025] As Figure 6 and Figure 7As shown in the figure, it further includes a third fixing bracket 23, a third fixing block 24, a third motor 25, a second bidirectional screw 26, a measuring device 27 and a precision meter 28. A third fixing bracket 23 is provided at the front side of the top of the support frame 1. A third fixing block 24 is fixedly connected to the left part of the third fixing bracket 23. A third motor 25 is provided inside the third fixing block 24. A second bidirectional screw 26 is fixedly connected to the output shaft of the third motor 25. A limiting block is provided directly above the second bidirectional screw. Measuring devices 27 are symmetrically and threadedly connected to the left and right sides of the second bidirectional screw 26. A precision meter 28 is provided in the middle of the front side of the third fixing block 24, and the measuring device 27 is electrically connected to the precision meter 28.

[0026] When double-sided grinding of the workpiece is required, this equipment can be used. First, add coolant to the water tank 15, then place the workpiece to be ground at the center position of the magnetic adsorption table 13, and turn on the switch of the magnetic adsorption table 13 to adsorb the workpiece on the magnetic adsorption table 13. Then start the servo motor 11, and the servo motor 11 drives the unidirectional screw 1101 to rotate, thereby driving the slider 12 to reciprocate, and then driving the magnetic adsorption table 13 to move. Then start the second motor 8 to drive the grinding wheel 9 to rotate clockwise. Subsequently, start the first motor 4, and the first motor 4 drives the first bidirectional screw 5 to rotate clockwise. The rotation of the first bidirectional screw 5 causes the two guide blocks 6 to move closer to each other. The movement of the guide blocks 6 drives the second fixing brackets 7, the second motors 8 and the grinding wheels 9 on the left and right sides to move closer to each other. When the two grinding wheels 9 come into contact with the two surfaces of the workpiece to be ground, the workpiece is ground. When the grinding wheel 9 moves to a suitable position, turn off the first motor 4 to prevent the improper movement position of the grinding wheel 9 from causing problems with the precision of the workpiece. The servo motor 11 drives the workpiece to reciprocate, so that the two surfaces of the workpiece can be evenly ground. During the grinding process, the grinding wheel 9 and the workpiece will generate high temperature, which is likely to cause the workpiece to overheat and deform. At this time, the pressing rod 20 can be pressed to the left, and the elastic member 22 is compressed. The pressing rod 20 moves to the left and presses the airbag 17. After the airbag 17 is pressed, the coolant in the water tank 15 will be sprayed out from the nozzle 19 and sprayed on the two surfaces of the workpiece being ground. After the workpiece is ground, turn off the second motor 8, move the magnetic adsorption table 13 to the front of the support frame 1 and then turn off the servo motor 11, and start the first motor 4 to drive the first bidirectional screw 5 to rotate counterclockwise. After driving the two second motors 8 away, turn off the first motor 4.

[0027] When the workpiece needs to be inspected for accuracy after grinding, since the magnetic chuck 13 has moved to the front of the support frame 1, the third motor 25 is then started. The third motor 25 drives the second bidirectional screw 26 to rotate clockwise, thereby driving the two measuring devices 27 to approach each other. When the measuring device 27 contacts the workpiece, the third motor 25 is turned off, and then the servo motor 11 is started to drive the magnetic chuck 13 to reciprocate, so that the measuring device 27 measures the accuracy of the entire surface of the workpiece. After the measuring device 27 contacts the workpiece, the measuring device 27 will send a signal to the accuracy meter 28, and the accuracy meter 28 will thus display the accuracy value. After the test, the third motor 25 is started to make the second bidirectional screw 26 rotate counterclockwise, so that the measuring devices 27 move away from each other. Finally, after the magnetic chuck 13 moves to the front of the support frame 1, the servo motor 11 and the switch of the magnetic chuck 13 are turned off, and the workpiece can be removed.

[0028] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
