[0001] The present invention relates to the technical field of grinding machines, and particularly to a planar automatic grinding machine. Background Art

[0002] A planar automatic grinding machine is an automated device used for high-precision planar grinding of the surface of workpieces, and is widely applied in industries such as metal processing, semiconductors, optical components, and mold manufacturing. Existing planar automatic grinding machines, such as the casing planar grinding machine disclosed in the invention patent with the publication number CN115502888B and the planar grinding machine disclosed in the invention patent with the publication number CN108214282B, etc., can all achieve the grinding of workpieces.

[0003] However, it is found during use that the structure of existing planar automatic grinding machines is relatively simple, it is inconvenient to replace the grinding bars during the grinding process, and it is difficult to complete the grinding of workpieces with different mesh numbers in one go, resulting in poor practicability. Therefore, it is urgently necessary to improve the existing planar automatic grinding machines to solve the above problems. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a planar automatic grinding machine that places a workpiece in a grinding mechanism, grinds the workpiece through the grinding mechanism, and replaces the components on the grinding mechanism through a replacement mechanism, achieving the grinding of workpieces with different mesh numbers in one go, thereby improving the practicability of the device.

[0006] The support mechanism supports the grinding mechanism and the replacement mechanism, and the grinding mechanism cooperates with the replacement mechanism to achieve the grinding of workpieces with different mesh numbers in one go;

[0007] Place the workpiece in the grinding mechanism, grind the workpiece through the grinding mechanism, and replace the components on the grinding mechanism through the replacement mechanism, achieving the grinding of workpieces with different mesh numbers in one go, thereby improving the practicability of the device.

[0008] Preferably, the support mechanism includes a first frame and a second frame, and the first frame is located below the second frame; the first frame and the second frame cooperate to support the grinding mechanism and the replacement mechanism, thereby improving the stability of the device.

[0009] Preferably, the grinding mechanism includes a driving mechanism, two grinding discs, a first hydraulic cylinder, a first driving motor, a first gear ring, a mold driving mechanism, and a bottom grinding disc are all installed on the first frame, the top grinding disc is installed on the second frame through the first hydraulic cylinder, and the top grinding disc is rotatably connected to the first hydraulic cylinder. The first driving motor is fixedly installed on the first hydraulic cylinder, the first gear ring is fixedly installed on the top grinding disc, and a first gear is arranged on the output shaft of the first driving motor. The first gear is meshed with the first gear ring, and the mold is placed between the two grinding discs. Place the workpiece in the mold, then place the mold on the bottom grinding disc, drive the mold to perform a forward circular motion between the two grinding discs through the driving mechanism, and at the same time, extend the first hydraulic cylinder to lower the top grinding disc, squeeze the workpiece through the two grinding discs, then turn on the first driving motor, and drive the top grinding disc to rotate in one direction through the meshing transmission of the first gear and the first gear ring, so that the two grinding discs cooperate with each other to grind the workpiece in the mold, thereby improving the practicability of the equipment.

[0010] Preferably, the driving mechanism includes a second hydraulic cylinder, a lifting table, a support ring, multiple first columns, a second gear ring, a speed reducer, a second driving motor, a second gear, multiple third hydraulic cylinders, a lifting ring, and multiple second columns. Multiple second hydraulic cylinders and multiple third hydraulic cylinders are all installed in the first frame. The lifting table is installed on the top of the second hydraulic cylinder. The support ring is rotatably installed on the top of the lifting table. Multiple first columns are all installed on the top of the support ring. The second gear ring is installed on the inner wall of the support ring. The speed reducer is fixedly installed on the lifting table. The second driving motor is fixedly installed on the speed reducer, and the output shaft of the second driving motor is connected to the input end of the speed reducer. The second gear is installed on the output shaft of the speed reducer, and the second gear is meshed with the second gear ring. The lifting ring is installed on multiple third hydraulic cylinders. Multiple second columns are all installed on the top of the lifting ring. Place the mold on the top of the bottom grinding disc, make the mold mesh with multiple first columns and multiple second columns, and make the support ring and the lifting ring support the mold. Then change the grinding requirements, extend or contract the second hydraulic cylinder and multiple third hydraulic cylinders to adjust the height of the mold. During grinding, turn on the second driving motor, drive through the speed reducer, and then drive the support ring to rotate through the meshing transmission of the second gear and the second gear ring, so that multiple first columns drive the mold to perform a circular motion, thereby improving the practicability of the equipment.

[0011] Preferably, the grinding disc includes a lifting mechanism, a housing, multiple sets of fixing frames, multiple sets of positioning columns, multiple sets of first springs, multiple sets of limiting frames, multiple sets of fourth hydraulic cylinders, multiple sets of pin columns, and multiple grinding bars. The lifting mechanism is installed in the housing, and multiple sets of fixing frames are all installed on the lifting mechanism. Multiple sets of positioning columns and multiple sets of first springs are respectively fixedly installed at one end of multiple sets of fixing frames, and multiple sets of positioning columns are respectively located in the middle of multiple sets of first springs. Multiple sets of limiting frames are respectively installed on multiple sets of fixing frames, multiple sets of fourth hydraulic cylinders are respectively installed on multiple sets of limiting frames, multiple sets of pin columns are respectively installed at one end of multiple sets of fourth hydraulic cylinders, and multiple grinding bars are respectively slidably installed in multiple sets of fixing frames. Limiting grooves are provided on multiple grinding bars, and permanent magnets I are provided at one end of multiple grinding bars. After inserting multiple grinding bars into multiple sets of fixing frames respectively, and squeezing multiple sets of first springs respectively through the other ends of multiple grinding bars, multiple sets of first springs are contracted until the other ends of multiple grinding bars respectively contact one end of multiple sets of positioning columns. Then, through the extension of multiple sets of fourth hydraulic cylinders, multiple sets of pin columns are respectively inserted into the limiting grooves of multiple grinding bars to limit multiple grinding bars respectively. Then, the height of multiple grinding bars is adjusted through the lifting mechanism. Then, through the relative movement between the workpiece and multiple grinding bars, multiple grinding bars grind the workpiece, thereby improving the practicability of the equipment.

[0012] Preferably, the lifting mechanism includes a first lifting frame, a second lifting frame, and multiple sets of fifth hydraulic cylinders. The multiple grinding bars are divided into two groups. The first lifting frame and the second lifting frame are respectively installed in the housing through multiple sets of fifth hydraulic cylinders. Two groups of grinding bars are respectively installed on the first lifting frame and the second lifting frame, and the mesh numbers of the two groups of grinding bars are different. Through the extension of some of the fifth hydraulic cylinders, the first lifting frame moves, and the grinding bars on the first lifting frame extend out of the housing to grind the workpiece. Then, some of the fifth hydraulic cylinders contract, moving the grinding bars on the first lifting frame into the housing. At the same time, through the extension of the remaining part of the fifth hydraulic cylinders, the grinding bars on the second lifting frame extend out of the housing to grind the workpiece again. Then, the grinding bars in the housing are replaced through the replacement mechanism. Then, repeat the above steps to grind the workpiece with grinding bars of different mesh numbers until the workpiece plane meets the requirements, thereby improving the practicability of the equipment.

[0013] Preferably, the replacement mechanism includes a following mechanism, multiple electric cylinders, and multiple second permanent magnets. The following mechanism is installed on the second frame, the multiple electric cylinders are all installed on the following mechanism, and the multiple second permanent magnets are respectively installed at one ends of the multiple electric cylinders. When replacing the abrasive strips in the top grinding disc, the height of the multiple electric cylinders is adjusted through the following mechanism, and the following mechanism rotates together with the top grinding disc. Then, the multiple fourth hydraulic cylinders contract, so that the multiple pin columns are respectively withdrawn from the limiting grooves of the multiple abrasive strips. Due to the elasticity of the first spring, one ends of the multiple abrasive strips extend outside the housing. Then, the multiple electric cylinders extend, so that the multiple second permanent magnets respectively attract the multiple first permanent magnets. Then, the multiple electric cylinders contract, and the multiple abrasive strips are withdrawn from the housing together. After that, the following mechanism resets. The operator replaces the abrasive strips attracted by the multiple second permanent magnets with those of a smaller mesh number, and then repeats the above steps. The replaced abrasive strips are inserted into the multiple fixing frames, and then the multiple abrasive strips are limited by the multiple pin columns respectively. Since the bottom grinding disc does not rotate, the multiple pin columns directly release the multiple abrasive strips, and the operator can directly replace them manually, thereby improving the practicability of the equipment.

[0014] Preferably, the following mechanism includes multiple sixth hydraulic cylinders, multiple second springs, a lifting frame three, and a following frame. The multiple sixth hydraulic cylinders are all installed on the second frame, the multiple second springs are respectively installed at the bottoms of the multiple sixth hydraulic cylinders, and telescopic rods for guiding are arranged in the middles of the multiple second springs. The lifting frame three is installed at the bottoms of the multiple second springs, and multiple pins are arranged at the top of the following frame. Multiple limiting holes are arranged at the top end of the top housing, and the following frame is rotatably installed at the bottom of the lifting frame three. By extending the multiple sixth hydraulic cylinders, the following frame is sleeved on the top housing, so that the multiple pins are pressed against the top of the top housing. At the same time, the multiple second springs contract, and along with the rotation of the top housing, the multiple pins are respectively inserted into the multiple limiting holes at the top end of the top housing. After that, restricted by the multiple pins, the following frame rotates together with the top housing, thereby improving the practicability of the equipment.

[0015] Preferably, a spray head is arranged at the top end of the bottom housing, and a drainage pipeline is arranged inside the bottom housing. Before grinding, the drainage pipeline is connected to a coolant delivery device, and coolant is sprayed through the spray head to cool the workpiece and the multiple abrasive strips, thereby improving the practicability of the equipment.

[0016] Preferably, rotatable steel balls are arranged at the bottoms of the multiple pins. Through the rotatable steel balls at the bottoms of the multiple pins, the friction between the multiple pins and the top housing is reduced, facilitating the pins to quickly extend into the limiting holes at the top end of the top housing, thereby improving the practicability of the equipment.

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

[0018] 1. Through the cooperation of the grinding mechanism and the replacement mechanism, the grinding of workpieces with different mesh numbers can be completed at one time without stopping the machine, improving the grinding efficiency.

[0019] 2. By grinding the top and bottom of the workpiece in opposite directions, the grinding effect is improved, and two surfaces of the workpiece are ground at one time.

Place the workpiece in the mold 7, and then place the mold 7 on the bottom grinding disk 3.
