[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing.

[0003] CNC grinder is a type of CNC machine tool, which refers to a machine tool that uses abrasive tools to grind the surface of a workpiece through CNC technology. However, the CNC grinder in the existing technology still has the following problems in its actual use:

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1 to 6 The present invention provides a technical solution: a high-precision CNC machine tool, comprising a machine tool bed 1 and a metal part 6, a cleaning frame 12 is arranged above the machine tool bed 1, a mounting block is fixedly connected to the upper surface of the machine tool bed 1, a fixing ring 11 is fixedly installed on the machine tool bed 1 through the mounting block, and a rotating ring 9 is connected to the upper surface of the fixing ring 11 for fixed-axis rotation;

[0037] The numerically controlled machine tool further comprises a switching component, a cleaning component and an auxiliary component which are arranged in the fixing ring 11 .

[0038] A fixed table 4 is fixedly installed on the surface of the machine tool bed 1, and a vertical plate 1 3 and a vertical plate 2 symmetrically arranged on the upper surface of the machine tool bed 1, a cleaning frame 12 is arranged below the vertical plate 1 3, and a grinding assembly 5 is arranged on the vertical plate 2;

[0039] The surface of the swivel ring 9 is rotatably connected to two symmetrically arranged swivel rods 22, the ends of the swivel rods 22 are fixedly connected to the fixed frame 7, the surface of the fixed frame 7 is provided with a hydraulic component 47, the output end of the hydraulic component 47 is fixedly installed with a back plate 48, and a rubber cushion layer is provided on the side of the back plate 48 away from the hydraulic component 47. Two back plates 48 are provided and are symmetrically distributed in the fixed frame 7, and the surface of the fixed ring 11 is fixedly connected to a support plate 23.

[0040] A controller 8 is provided on the surface of the machine tool bed 1 , and a numerical control box 10 is fixedly mounted on the lower surface of the machine tool bed 1 .

[0041] More specifically, in this embodiment: Figure 1 and Figure 2 As shown, a metal part 6 that needs to be ground is placed in the fixed frame 7 below the right vertical plate 2. After the placement is completed, the metal part 6 will be located above the support plate 23. The setting of the support plate 23 can provide auxiliary support when the two abutment plates 48 in the fixed frame 7 are not fixed to the metal part 6.

[0042] Next, the two hydraulic components 47 in the fixed frame 7 are controlled to work simultaneously, so that the two abutment plates 48 move toward each other until the two abutment plates 48 are in contact with the surface of the metal part 6. At this time, under the action of the pressure of the hydraulic component 47, the metal part 6 can be fixed in the fixed frame 7.

[0043] Further, the switching component includes a motor 19 disposed in the fixed ring 11, the output shaft of the motor 19 is fixedly connected to the rotating shaft 20, the surface of the rotating shaft 20 is fixedly connected to the rotating disk 13, the surface of the rotating disk 13 is provided with two symmetrically arranged rectangular notches 46, the inner wall of the rectangular notch 46 is fixedly mounted with a piston cylinder 41, the inner wall of the rectangular notch 46 is slidably connected with a wedge block 39, and a spring 37 is provided between the wedge block 39 and the piston cylinder 41;

[0044] The surface of the rotating ring 9 is provided with four groups of arc-shaped cut surfaces 44 and right-angle cut surfaces 45 distributed in a circumferential array.

[0045] The surface of the rotating rod 22 is fixedly connected with a gear 21 , and the inner wall of the fixing ring 11 is fixedly connected with a rack 43 meshing with the gear 21 .

[0046] After a metal part 6 is fixed, Figure 3 and Figure 6 As shown, the motor 19 is turned on, driving the rotating shaft 20 and the turntable 13 to rotate 180 degrees clockwise. As the turntable 13 rotates, the two wedge blocks 39 will be driven to rotate synchronously. In this state, the clockwise rotation of the wedge block 39 will contact the right-angle section 45 on the rotating ring 9. As the wedge block 39 rotates, the rotating ring 9 can be pushed to rotate 180 degrees clockwise. As the rotating ring 9 rotates, under the connecting action of the rotating rod 22, the two fixed frames 7 will switch their positions, so that the fixed frame 7 equipped with the metal part 6 can be switched to the bottom of the vertical plate 1 3, and the fixed frame 7 without the metal part 6 will be switched to the bottom of the vertical plate 2 2.

[0047] Similarly, a second metal part 6 that needs to be ground is placed in the fixed frame 7 below the second vertical plate 2, and then the corresponding two hydraulic components 47 are controlled to complete the fixation of the metal part 6 in the second fixed frame 7, so as to complete the loading operation of the metal parts 6 in the two fixed frames 7.

[0048] Further, the cleaning component includes a connecting block 32 fixedly connected to the lower surface of the fixed platform 4, the end of the connecting block 32 is fixedly connected to the shell 131, the surface of the shell 131 is connected to the cleaning pipe 16 by fixed axis rotation, the end of the cleaning pipe 16 is fixedly connected to the cleaning frame 12, and the lower surface of the cleaning frame 12 is evenly provided with a plurality of air outlets 17, the lower surface of the vertical plate 13 is fixedly connected to the fixing sleeve 15, the cleaning pipe 16 penetrates the fixing sleeve 15 and is connected to the fixing sleeve 15 by fixed axis rotation, the lower surface of the shell 131 is fixedly connected to the connecting pipe 130, the end of the connecting pipe 130 is fixedly connected to the shell 29, and the surface of the shell 29 is connected to the connecting pipe 27 by fixed axis rotation;

[0049] The inner wall of the piston cylinder 41 is slidably connected to a piston plate, the surface of the piston plate is fixedly connected to a piston rod 40, one end of the piston rod 40 extending out of the piston cylinder 41 is fixedly connected to a wedge block 39, the surface of the piston cylinder 41 is fixedly connected to an air supply pipe 26, and the end of the air supply pipe 26 is fixedly connected to a connecting pipe 27.

[0050] The surface of the piston cylinder 41 is also fixedly connected to an air intake pipe 42, the surface of the air intake pipe 42 is provided with a one-way valve 1, the surface of the air supply pipe 26 is provided with a one-way valve 2, the surface of the turntable 13 is fixedly installed with a protective shell 1 24, and the lower surface of the fixed platform 4 is fixedly installed with a protective shell 2 14.

[0051] A clutch is provided at the connection between the rotating ring 9 and the fixed ring 11. Under the action of the clutch, the limiting rotating ring 9 can only rotate clockwise. This is a relatively mature prior art in the field of clutches and will not be described in detail here.

[0052] like Figure 3 , Figure 5 and Figure 6 As shown, after the loading operation of the metal parts 6 in the two fixed frames 7 is completed, the motor 19 is turned on again to drive the rotating shaft 20 and the turntable 13 to rotate counterclockwise. As the turntable 13 rotates counterclockwise, the wedge block 39 will rotate counterclockwise and contact the arc-shaped section 44 of the turntable 13. Since the turntable 13 cannot rotate counterclockwise, at this time, as the wedge block 39 moves, the arc-shaped section 44 will squeeze the wedge block 39 toward the inside of the rectangular notch 46.

[0053] As the wedge block 39 moves toward the inside of the rectangular groove 46, the piston rod 40 will drive the piston plate to move toward the inside of the piston cylinder 41, and the spring 37 will be compressed at the same time, so that the air stored in the piston cylinder 41 can be discharged to the connecting pipe 27 through the air supply pipe 26. The gas transported to the connecting pipe 27 will pass through the shell 2 29, the connecting pipe 1 30, the shell 1 31, the cleaning pipe 16 and the cleaning frame 12 in sequence, and will finally be evenly sprayed out through the multiple air outlets 17 on the lower surface of the cleaning frame 12, so as to clean the dust and impurities on the surface of the metal part 6 below that has not yet been ground, thereby avoiding the problem that the dust and impurities on the surface of the metal part 6 will affect the subsequent grinding process accuracy.

[0054] It is worth noting that as the wedge block 39 moves, after the wedge block 39 rotates 90 degrees around the rotating shaft 20, it will disengage from the arc section 44 of the turntable 13. Under the action of the elastic potential energy of the spring 37, the wedge block 39 will be pushed to move and reset in the direction away from the rectangular notch 46. That is, as the motor 19 is turned on, every time the turntable 13 rotates counterclockwise, the wedge block 39 will drive the piston rod 40 and the piston plate to reciprocate four times in the piston cylinder 41. Correspondingly, the piston cylinder 41 will deliver gas to the cleaning frame 12 four times until the dust and impurities on the surface of the metal part 6 are cleaned.

[0055] After the dust and impurities on the surface of the metal part 6 are cleaned, the motor 19 is turned on again to drive the rotating shaft 20 and the turntable 13 to rotate 180 degrees clockwise, so that the cleaned metal part 6 can be switched to the bottom of the vertical plate 2.

[0056] like Figure 1 and Figure 2 As shown, the grinding assembly 5 includes two staggered slide rails, a telescopic component, an angle adjustment component, a driving component and a grinding disc. When the grinding assembly 5 cooperates with the programming of the CNC machine tool, the grinding disc can perform multi-position and multi-angle grinding processing on the upper surface of the metal part 6, so as to accurately complete the grinding processing operation of the metal part 6. This is a relatively mature existing technology in the field of CNC machine tools and will not be described in detail here.

[0057] After the grinding operation of one processing surface of the metal part 6 is completed, the motor 19 is turned on first to drive the rotating shaft 20 and the turntable 13 to rotate counterclockwise to clean the surface of the left metal part 6. After the cleaning is completed, the motor 19 is turned on again to drive the rotating shaft 20 and the turntable 13 to rotate 180 degrees clockwise, and the cleaned metal part 6 on the left can be switched to the bottom of the grinding assembly 5 again. Similarly, the metal part 6 after grinding on one side will also be switched to the bottom of the cleaning frame 12, and the grinding operation of the other metal part 6 can be carried out at this time.

[0058] It is worth noting that Figure 5 and Figure 6 As shown, when the metal part 6 that has been polished on the right side is rotated 180 degrees around the rotating shaft 20 to switch its position, as the rotating rod 22 moves, the gear 21 fixedly connected on its surface will contact with the rack row 43, so that the rotating rod 22 can rotate 180 degrees while revolving around the rotating shaft 20, so that the metal part 6 that has been polished on the right side can be self-flipped 180 degrees when switched to the left side, so that the unprocessed side can be flipped upwards, without removing the metal part 6 for manual flipping, that is, after the grinding operation on one side of the metal part 6 is completed, the flipping operation of the metal part 6 can be automatically completed. This automated flipping process greatly reduces the time and cost of manual flipping, and improves the overall processing efficiency. At the same time, compared with manual flipping, mechanized flipping is more stable, which can ensure that the metal part will not be damaged during the flipping process, further ensuring the processing efficiency.

[0059] After the metal part 6 has flipped over and switched positions, the motor 19 is turned on again to drive the rotating shaft 20 and the rotating disk 13 to rotate counterclockwise, so that the side of the metal part 6 that has not been ground after flipping upward can be cleaned by jetting.

[0060] Embodiment 2, based on the above embodiment:

[0061] Further, the auxiliary component in the first embodiment is disclosed as follows: the auxiliary component includes an articulated block 1 38 fixedly connected to the upper surface of the wedge block 39, a moving block 28 is slidably connected to the surface of the connecting pipe 1 30, an articulated block 2 is fixedly installed on the surface of the moving block 28, and an articulated plate 36 is provided between the articulated block 2 and the articulated block 1 38;

[0062] A connecting plate 35 is fixedly connected to the surface of the moving block 28 , and a second rack row 34 is fixedly installed on the moving block 28 through the connecting plate 35 . A second gear 33 meshing with the second rack row 34 is fixedly connected to the surface of the cleaning tube 16 .

[0063] More specifically, when this embodiment is used: Figure 4 and Figure 5As shown, when the motor 19 is turned on, the rotating shaft 20 and the turntable 13 are driven to rotate counterclockwise to clean the metal part 6 under the upright plate 13, as the wedge block 39 reciprocates in the rectangular notch 46, under the hinged action of the hinged plate 36, the moving block 28 will be driven to reciprocate in the vertical direction along the connecting pipe 1 30, and the reciprocating movement of the moving block 28 will drive the connecting plate 35 and the rack row 2 34 to reciprocate in the vertical direction synchronously. As the rack row 2 34 reciprocates, it will reciprocately mesh with the gear 2 33, so that the gear 2 33 can drive the cleaning pipe 16 to reciprocate, so that the cleaning frame 12 can reciprocate slightly while jetting to clean the metal part 6. On the one hand, the cleaning area of ​​the cleaning frame 12 can be increased, and on the other hand, the gas ejected obliquely by the cleaning frame 12 after deflection can better blow off the dust and impurities on the surface of the metal part 6, and the cleaning effect is stronger.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
