[0024] As Figures 1 to 3 shown, a high-efficiency quantitative grinding and polishing machine includes a housing base 1, a grinding disc 2 is provided on the housing base 1, and an upper polishing head mechanism 3 corresponding to the grinding disc 2. A grinding disc driving device for driving the rotation of the grinding disc 2 is provided inside the housing base 1. The grinding disc is driven by the grinding disc driving device to rotate to grind and polish the specimen; the upper polishing head mechanism 3 has a frame 31 fixedly provided on the top of the housing base 1. A shaft seat 33 is provided on one side of the frame 31. A main shaft 34 is slidably and rotatably provided on the shaft seat 33 in the vertical direction. A rotation driving assembly 39 for driving the rotation of the main shaft 34 is provided on the shaft seat 33. A polishing seat assembly 32 is provided at the lower end of the main shaft 34. A dial indicator 35 corresponding to the upper end of the main shaft is erected above the shaft seat 33; during the grinding and polishing process, the grinding and polishing amount of the specimen can be accurately measured in real time through the dial indicator 35. At the same time, the dial indicator 35 is linked with the grinding disc 2. When the preset grinding and polishing amount is reached, the grinding disc 2 is stopped to accurately control the grinding and polishing amount for setting a specific grinding and polishing thickness; among them, the dial indicator 35 adopts a signal output type digital display dial indicator. When in use, the dial indicator 35 is connected to a controller. The controller obtains the grinding and polishing amount through the dial indicator 35. When the preset grinding and polishing amount is reached, the controller controls the grinding disc driving device to stop rotating, and the controller can adopt a PLC controller.

[0025] As a specific embodiment of the rotation driving assembly 39, as Figure 2 and 3 shown, the rotation driving assembly 39 has a driven wheel 392 fixedly sleeved outside the main shaft 34. A driving wheel 391 corresponding to the driven wheel 392 is arranged on the shaft seat 33. The driving wheel 391 is driven to rotate by a rotation motor (the rotation motor is not shown in the figure). The rotation motor is assembled inside the shaft seat 33. The driving wheel 391 and the driven wheel 392 are connected by a transmission belt in a transmission manner; the rotation motor drives the driving wheel 391 to rotate. The driving wheel 391 drives the driven wheel 392 to rotate through the transmission belt. When the driven wheel 392 rotates, it drives the main shaft 34 and the polishing seat assembly 32 at its lower end to rotate, and grinds and polishes the specimen installed at the bottom of the polishing seat assembly 32; among them, the transmission belt can be a transmission belt with certain elasticity, which can ensure good transmission effect between the driving wheel 391 and the driven wheel 392 when the driven wheel 392 floats up and down.

[0026] In some embodiments, a push plate 4 is rotatably arranged on one side of the shaft seat 33. A push plate locking bolt 41 for locking or releasing between the push plate 4 and the shaft seat 33 is arranged on the push plate 4. Rotating the push plate 4 upward can push the driven wheel 392 upward. When the driven wheel 392 moves upward, it will drive the main shaft 34 and the polishing seat assembly 32 at its lower end to move upward. The polishing seat assembly 32 is supported by the push plate 4, which is convenient for installing and replacing the specimen at the bottom of the polishing seat assembly 32. After adjusting the push plate 4, the push plate 4 can be locked with the shaft seat 33 through the push plate locking bolt 41 to keep the push plate 4 stable. When the push plate 4 needs to be adjusted again, just loosen the push plate locking bolt 41; one end of the push plate 4 corresponding to the driven wheel 392 has an arc surface 411. By contacting the bottom of the driven wheel 392 through the arc surface 411, the arc surface 411 can make the contact between the driven wheel 382 and the push plate 4 smooth during the process of rotating the push plate 4 to push the driven wheel 392 upward.

[0027] In some embodiments, a locking support 331 is fixedly arranged on one side of the shaft seat 33. A bolt 332 is slidably arranged on the locking support 331 in the vertical direction. A bolt locking bolt 333 for locking or releasing between the bolt 332 and the locking support 331 is threadedly connected to the lower end of the bolt 332. A jack 3921 matching the upper end of the bolt 332 is provided on the driven wheel 392. During the grinding and polishing process where the polishing seat assembly 32 does not need to rotate, inserting the bolt 332 into the jack 3921 can lock the driven wheel 392, restrict the rotation of the driven wheel 392, thereby locking the main shaft 34 and restricting the rotation of the polishing seat assembly 32. At the same time, the bolt 332 is slidably connected to the jack 3921, which does not affect the downward movement of the main shaft 34 and the driven wheel 392 during the grinding and polishing process. The bolt locking bolt 333 is threadedly connected to the side surface of the lower end of the bolt 332 along the radial direction of the bolt 332. Tightening the bolt locking bolt 333 can lock between the bolt 332 and the locking support 331, and loosening the bolt locking bolt 333 can release between the bolt 332 and the locking support 331.

[0028] In some embodiments, the high-efficiency quantitative grinding and polishing machine further includes a swing drive assembly 36. The swing drive assembly 36 has a swing motor 362 fixed on the side of the frame 31. A drive wheel 361 is assembled on the swing motor 362. A connecting rod 363 is connected between the drive wheel 361 and the shaft seat 33. One end of the connecting rod 363 is hinged to the shaft seat 33, and the other end of the connecting rod 363 is eccentrically hinged to the drive wheel 361. There is a hinge seat 37 on one side of the frame 31. The shaft seat 33 is rotationally connected to the hinge seat 37. The swing motor 362 drives the drive wheel 361 to rotate. When the drive wheel 361 rotates, it drives the shaft seat 33 to swing reciprocally through the connecting rod 363. The swing drive assembly 36 drives the shaft seat 33 to drive the specimen below the chuck polishing seat assembly 32 to swing reciprocally, which can significantly increase the relative speed between the specimen and the grinding disc 2, improve the grinding and polishing efficiency. At the same time, during the swinging process of the specimen, the relative position between the specimen and the grinding disc 2 can be continuously adjusted, improving the grinding and polishing accuracy.

[0029] In some embodiments, the hinge seat 37 is slidably arranged in the vertical direction on one side of the frame 31. A height adjustment assembly 38 for adjusting the height of the hinge seat 37 is arranged on the frame 31. The height adjustment assembly 38 has a top plate 381 fixedly arranged on the top of the frame 31. A lead screw 382 is arranged in the vertical direction on the top plate 381. The lead screw 382 is rotationally connected to the top plate 381. The hinge seat 37 is threadedly connected to the lead screw 382. A hand wheel 383 is fixedly arranged at the upper end of the lead screw 382. By rotating the hand wheel 383 to rotate the lead screw 12, the threaded structure between the lead screw 12 and the hinge seat 37 is matched, which can drive the hinge seat 37 to move up and down, thereby adjusting the distance between the polishing assembly 32 and the specimen below it and the grinding disc 2.

[0030] As a specific embodiment of the polishing seat assembly 32, such as Figures 4 to 7As shown, the polishing seat assembly 32 has a polishing seat 321. The bottom of the polishing seat 321 is elastically connected with a chuck 322. The bottom of the chuck 322 is detachably and fixedly provided with a fixture 323. One side of the fixture 323 is provided with a dial indicator head seat 324 for installing a dial indicator. At least two micrometer knobs 329 are vertically assembled on the top of the polishing seat 321, and the end of the micrometer knob 329 abuts against the top of the chuck 322. Vertically install a dial indicator at the end of the dial indicator head seat 4 so that the end of the dial indicator contacts the grinding disc 2. Then start the grinding disc 2 to make it rotate, and observe the numerical jump of the dial indicator on the dial indicator head seat 4. When the numerical jump range is relatively large, adjust the inclination of the chuck 322 by screwing the micrometer knob 329 on the top of the polishing seat 321 to improve the parallelism between the fixture 323 and the grinding disc 2, so as to narrow the numerical jump range of the dial indicator. When the numerical jump range enters the allowable error range, it can be used for grinding and polishing processing to improve the grinding and polishing accuracy.

[0031] In some embodiments, corresponding channels 3212 are formed on the polishing seat 321 and the chuck 323. A tension spring 327 is arranged inside the channel 3212. Tension spring pins 328 are arranged inside the channels 3212 of the polishing seat 321 and the chuck 322. The end of the tension spring 328 is hung on the corresponding tension spring pin 328. Due to the elastic force exerted by the tension spring 327, there is a tendency for the polishing seat 321 and the chuck 322 to approach each other. When the micrometer knob 329 is screwed to push the chuck 322 downward, the tension spring 327 is stretched. When the micrometer knob 329 is screwed and its end is retracted upward, the chuck 322 is reset upward under the elastic force of the tension spring 327.

[0032] In some embodiments, an eccentric shaft 325 is arranged on the chuck 322 along its radial direction. The eccentric shaft 325 is rotatably connected with the chuck 322. A lower chuck 326 is slidably arranged inside the chuck 322 along its axial direction. A groove 3261 matching the end of the eccentric shaft 325 is formed on the lower chuck 326. A clamping groove 3231 matching the lower chuck 326 is formed on the fixture 323. The fixture 323 is assembled at the lower end of the lower chuck 326 through the clamping groove 3231. By screwing the eccentric shaft 325, the eccentric end of the eccentric shaft 325 cooperates with the groove 3261 to drive the lower chuck 326 to move up and down, and the fixture 323 is locked or released by the lower chuck 326.

[0033] In some embodiments, the bottom of the lower chuck 326 has a T-shaped chuck 3262, and the clamping groove 3231 is matched with the T-shaped chuck 3262; a handle 3251 is provided at one end of the eccentric shaft 325 away from the chuck 322, and the handle 3251 facilitates screwing the eccentric shaft 325 to lock or release the fixture 323; a guide pin 3211 is assembled between the polishing seat 321 and the chuck 322. Installation holes matching the guide pin 3211 are provided on both the polishing seat 321 and the chuck 322. There is an assembly gap between the guide pin 3211 and the installation hole to prevent the guide pin 3211 from affecting the movement of the chuck 322 during the process of fine-tuning the angle of the chuck 322.
