[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to the attached Figure 1 - attached Figure 6, an embodiment of the present invention provides a multi-axis linkage numerical control cylindrical grinding machine grinding device, which includes a grinding machine workbench 1. A track table 2 is fixedly connected to the top of the grinding machine workbench 1. An active clamping table 3 is arranged on the top of the track table 2. A grinding device 4 is fixedly connected to one side of the top of the track table 2. A driving table 5 is fixedly connected to the top of the track table 2. A motor 6 is installed on the outside of the driving table 5. Sprockets 7 are arranged at the output end of the motor 6 and inside the grinding machine workbench 1. A chain 8 is sleeved outside the two sprockets 7. A transmission rod 9 is rotatably connected to the inside of the driving table 5. Cylindrical gears 10 are fixedly connected to the outside of the upper sprocket 7 and one end of the transmission rod 9. The two cylindrical gears 10 are meshed. A clamping head 11 is fixedly connected to the other end of the transmission rod 9. In actual operation, the rotation of the handle 35 drives the movable rod 34 to rotate, and then the rotating sleeve 32 is rotated through the connecting block 36. Since the rotating sleeve 32 is meshed with the lifting screw rod 14 through the bevel gear 15, the lifting screw rod 14 rotates accordingly. Pushing the handle 35 towards the dial block 30 is to enable the dial block 30 to be smoothly inserted into the strip-shaped groove 37 to achieve power transmission. Under the action of the tension spring telescopic rod 39, the rotating plate 40 has its card slot 41 engaged with the handle 35 to ensure the fixed position of the handle 35 during operation, so that the dial block 30 is in stable contact with the strip-shaped groove 37 and ensure the stability of power transmission. A water receiving groove 12 is opened on the top of the grinding machine workbench 1. The water receiving groove 12 is located on the top of the grinding machine workbench 1, and its function is to collect the coolant sprayed on the workpiece. A fixing frame 13 is fixedly connected to the inner wall of the water receiving groove 12. The fixing frame 13 is fixed to the inner wall of the water receiving groove 12 to provide support and guidance for the sliding of the I-shaped frame 16. An I-shaped frame 16 is slidably connected to the inside of the fixing frame 13. Two V-groove supporting blocks 17 are fixedly connected to the top end of the I-shaped frame 16. A lifting screw rod 14 is rotatably connected to the bottom of the fixing frame 13. A guide rod 18 is fixedly connected to the bottom of the fixing frame 13. The inside of the I-shaped frame 16 is threadedly connected to the outside of the lifting screw rod 14. When the lifting screw rod 14 rotates, since the I-shaped frame 16 is threadedly connected to the lifting screw rod 14 and can only move up and down linearly under the restriction of the guide rod 18, the I-shaped frame 16 will drive the V-groove supporting blocks 17 to rise or fall. A circulation hole 19 is opened on the inner wall of the water receiving groove 12. A reservoir 20 is opened inside the grinding machine workbench 1. The reservoir 20 is communicated with the circulation hole 19. The coolant flows from the circulation hole 19 of the water receiving groove 12 into the inside of the reservoir 20. During this process, a filter screen 27 is arranged inside the reservoir 20 to filter the coolant and intercept the impurities therein, so that the clean coolant can be reused. A reciprocating screw rod 21 is rotatably connected to the inside of the grinding machine workbench 1. After the motor 6 is started, the sprocket 7 at its output end rotates. Under the drive of the chain 8, the lower sprocket 7 rotates synchronously, thereby driving the reciprocating screw rod 21 fixedly connected thereto to rotate.One end of the reciprocating lead screw 21 is fixedly connected to the outer side of the lower sprocket 7. A threaded block 22 is threadedly connected to the outer side of the reciprocating lead screw 21. The outer side of the threaded block 22 is slidably connected to the inner wall of the grinding machine table 1. The threaded block 22 will move linearly along the inner wall of the grinding machine table 1 on its outer side. A bottom of the threaded block 22 is fixedly connected to an L-shaped rod 23. Since the threaded block 22 is fixedly connected to the L-shaped rod 23, the L-shaped rod 23 will move together with the threaded block 22. One end of the L-shaped rod 23 is fixedly connected to a piston 25. A water pumping tank 24 is fixedly connected to the inside of the grinding machine table 1. The outer side of the piston 25 is fixedly connected to the inner wall of the water pumping tank 24, thereby driving the piston 25 to reciprocate in the water pumping tank 24. Under the action of the check valves inside the water inlet pipe 26 and the water outlet pipe 28, the coolant can only be sucked into the water pumping tank 24 from the reservoir 20 through the water inlet pipe 26, and then be delivered to the spray head 29 through the water outlet pipe 28, realizing continuous spraying and cooling of the workpiece. One end of the water pumping tank 24 is fixedly connected to the water inlet pipe 26. One end of the water inlet pipe 26 extends into the inside of the reservoir 20. The outer side of the water pumping tank 24 is fixedly connected to the water outlet pipe 28. One end of the water outlet pipe 28 is fixedly connected to the spray head 29. The spray head 29 is fixedly connected to the outer side of the grinder 4. Check valves are arranged inside both the water inlet pipe 26 and the water outlet pipe 28. A fixing ring 31 is fixedly connected to the inside of the grinding machine table 1. A rotating sleeve 32 is rotatably connected to the inner side of the fixing ring 31. Bevel gears 15 are fixedly connected to both the outer side of the rotating sleeve 32 and the bottom of the lifting lead screw 14. The two bevel gears 15 are meshed. Two fixing blocks one 33 are fixedly connected to the outer side of one end of the rotating sleeve 32. An active rod 34 is slidably connected to the inside of the rotating sleeve 32. One end of the active rod 34 is fixedly connected to an engaging block 36. A strip-shaped groove 37 is formed in the outer side of the engaging block 36. A dial block 30 is fixedly connected to one end of the reciprocating lead screw 21. The outer side of the dial block 30 is fitted to the inner side of the strip-shaped groove 37. Two groups of fixing plates two 38 are fixedly connected to the outer side of the engaging block 36. The outer side of the fixing block one 33 is slidably connected to the inner side of the fixing plate two 38. The other end of the active rod 34 is fixedly connected to a handle 35. A tension spring telescopic rod 39 is fixedly connected to the outer side of the grinding machine table 1. One end of the tension spring telescopic rod 39 is rotatably connected to a rotating plate 40. A clamping groove 41 is formed in the outer side of the rotating plate 40. The outer side of the handle 35 is clamped inside the clamping groove 41.

[0022] Specifically, first adjust the height of the workpiece. Grasp the handle 35 and synchronously complete the actions of rotation and pushing in the direction of the shifting block 30. This operation has a dual effect: rotating the handle 35 can drive the movable rod 34 to rotate, and through the connecting block 36, the rotating sleeve 32 also rotates accordingly; while pushing the handle 35 in the direction of the shifting block 30 is to enable the shifting block 30 to be smoothly engaged in the strip-shaped groove 37, thereby achieving effective power transmission. Then rotate the rotating plate 40 to accurately engage the handle 35 with the clamping groove 41. At this time, under the pulling force of the tension spring telescopic rod 39, the shifting block 30 maintains stable contact with the strip-shaped groove 37, providing a reliable guarantee for subsequent power transmission. Subsequently, start the motor 6, and the sprocket 7 at the output end of the motor 6 starts to rotate. Since the two sprockets 7 are connected by a chain 8, the lower sprocket 7 will rotate synchronously, thereby driving the reciprocating lead screw 21 fixed to it to rotate. The shifting block 30 rotates with the reciprocating lead screw 21, driving the connecting block 36 to rotate, causing the two bevel gears 15 to rotate, and further enabling the lifting lead screw 14 to rotate. Because the I-shaped frame 16 is threadedly connected to the lifting lead screw 14 and is restricted by the guide rod 18, the I-shaped frame 16 will drive the two V-groove supports 17 to move upward. The effect of this process is that when the workpiece to be processed is placed in the V-shaped groove at the top of the V-groove support 17, it can be smoothly moved to an appropriate height to prepare for subsequent clamping operations. After the height of the workpiece is adjusted appropriately, start the movable clamping table 3 and the clamping head 11. The movable clamping table 3 moves along the track table 2 and, together with the clamping head 11, firmly clamps the workpiece. In this way, the workpiece will not displace during the subsequent grinding process, ensuring the grinding accuracy. After the workpiece is firmly clamped, start the motor 6 to reverse. The reverse rotation of the motor 6 causes the reciprocating lead screw 21 to rotate in the opposite direction, the threaded block 22 moves in the opposite direction, driving the L-shaped rod 23 and the piston 25 to move in the opposite direction. At the same time, the lifting lead screw 14 also rotates in the opposite direction, and the I-shaped frame 16 drives the V-groove support 17 to descend. When the V-groove support 17 descends to a certain position, it can avoid interference with the grinder 4 during the grinding process, ensuring the smooth progress of the grinding operation. Then, pull the handle 35 to separate the shifting block 30 from the connecting block 36. At this time, the power transmission path is cut off, and the grinder 4 can start grinding the workpiece. During the grinding process, the coolant circulation system plays an important role. After the motor 6 is started, the reciprocating lead screw 21 rotates, the threaded block 22 drives the L-shaped rod 23 to move, causing the piston 25 to perform reciprocating motion in the water pumping tank 24. Under the action of the one-way valves inside the water inlet pipe 26 and the water outlet pipe 28, the coolant is sucked from the reservoir 20 through the water inlet pipe 26 into the water pumping tank 24 and then delivered to the nozzle 29 through the water outlet pipe 28 to continuously spray and cool the workpiece. The continuous spraying of the coolant has multiple effects: it can effectively reduce the heat generated by friction during the grinding process of the workpiece, prevent the workpiece from deforming due to excessive temperature, thereby ensuring the machining accuracy of the workpiece; at the same time, the coolant can also wash away impurities such as iron filings generated during the grinding process, avoiding these impurities from scratching the surface of the workpiece and improving the surface quality of the workpiece.The coolant sprayed on the workpiece will flow into the water collecting tank 12 at the top of the grinding machine workbench 1. After the water collecting tank 12 collects the coolant, the coolant flows into the interior of the reservoir 20 through the circulation hole 19. During this process, the filter screen 27 filters the coolant, intercepting impurities such as iron filings and abrasive particles, so that the clean coolant can be reused. This way of recycling the coolant can not only avoid excessive waste of the coolant, reduce production costs, but also reduce environmental pollution.

[0023] Working principle: First, the handle 35 can be grasped and rotated while pushing it in the direction of the dial block 30, so that the dial block 30 is snapped into the interior of the strip-shaped groove 37. At this time, the rotating plate 40 is rotated so that the handle 35 is correspondingly engaged with the card slot 41. Under the pulling force of the tension spring telescopic rod 39, the dial block 30 is always in contact with the strip-shaped groove 37. Then, the motor 6 is started to drive the sprocket 7 to rotate. Driven by the chain 8, the reciprocating lead screw 21 rotates. In this way, the dial block 30 can drive the connecting block 36 to rotate, so that the two bevel gears 15 rotate, and then the lifting lead screw 14 rotates, and then the I-shaped frame 16 drives the two V-groove supporting blocks 17 to move upward. At this time, the workpiece to be processed can be placed in the V-shaped groove on the top of the V-groove supporting block 17, so that the workpiece to be processed can be moved to a suitable height. Then, the movable clamping table 3 and the clamping head 11 are started to clamp the workpiece. After that, the motor 6 is reversed to lower the position of the V-groove supporting block 17. Then, the handle 35 is pulled to separate the dial block 30 from the connecting block 36, and then the grinding process can be carried out; during grinding, the coolant can be stored in the interior of the reservoir 20 first. In this way, when the motor 6 is started, the reciprocating lead screw 21 will rotate, and the threaded block 22 can drive the L-shaped rod 23 to move, so that the piston 25 reciprocates in the water pumping tank 24. The coolant is sucked into the water pumping tank 24 through the water inlet pipe 26 and then conveyed to the nozzle 29 through the water outlet pipe 28 to continuously spray and cool the workpiece. At the same time, the coolant will flow back into the interior of the reservoir 20 through the circulation hole 19 at the position of the water collecting tank 12 and is filtered by the circulation hole 19 and can be reused to avoid excessive waste of the coolant.
