Description

Technical Field

[0001] The utility model relates to the field of integrated milling and grinding machines, in particular to a high-precision integrated milling and grinding machine for grinding wheels. Background Art

[0002] With the development of industrialization, the processing of large equipment accessories often requires milling and grinding of the surfaces of relatively large metal parts. Existing milling machines or grinders can only perform a single processing step, which is either milling or grinding. When a metal part needs to be milled and ground, it needs to be completed by using a milling machine and a grinder respectively in two steps. As a result, when the metal part changes between the milling and grinding steps, it is necessary to hoist the metal part between the milling and grinding steps, which ultimately leads to the shortcomings of low production efficiency, high workload and high production cost. In addition, the worktable and base of the current milling machine or grinder generally only use a conventional single set of slide rails and sliders as a sliding assembly. The sliding assembly of this structure is only suitable for use on relatively light worktables and metal workpieces. If a relatively heavy worktable or metal workpiece is encountered, it will usually cause the worktable to slide unstablely, with poor sliding accuracy, or even tilt. In addition, the horizontal moving box of a traditional milling machine or grinder is generally arranged on a vertical surface on one side of the gantry beam, and the horizontal moving box and its components are mounted on the vertical side of the gantry beam. The gantry beam is easily twisted due to the gravity of the horizontal moving box and its components, which reduces the straightness of the horizontal sliding of the horizontal moving box. The horizontal moving box is prone to shaking during the horizontal sliding process, thereby affecting the accuracy of the milling and grinding of the metal workpiece, resulting in reduced processing accuracy of the metal workpiece, which reduces the quality of the finished metal workpiece and the yield rate of the finished product.

[0067] In one embodiment, the structural design principle and working process of the high-precision milling and grinding machine with a grinding wheel are as follows: first, the workpiece to be processed is placed on the electric permanent magnetic chuck 6. When the first servo motor 29 rotates forward and reverse, it can drive the first pulley assembly 20 to rotate forward and reverse synchronously. The first pulley assembly 20 rotating forward and reverse drives the worktable 5 to slide back and forth on the base 21 through the first screw assembly 25, so that the workpiece sucked by the electric permanent magnetic chuck 6 can move back and forth with the worktable 5. When the workpiece moves with the worktable 5 in a direction away from the milling mechanism 8 and the grinding mechanism 9, it is convenient to unload the workpiece that has been processed and to load the next workpiece to be processed. When the workpiece moves with the worktable 5 in the direction of the milling mechanism 8 and the grinding mechanism 9, it can be transferred to the bottom of the milling mechanism 8 and the grinding mechanism 9 to prepare for the processing operation.

[0068] The base 21 in the base assembly 2 is provided with a flat rail 23 and a V-shaped rail 24, and a flat guide bar 51 and a V-shaped guide bar 52 are provided under the bottom surface of the workbench 5, so that the flat rail 23 on the base 21 can be adapted and installed with the flat guide bar 51 under the workbench 5, and the V-shaped rail 24 on the base 21 can be adapted and installed with the V-shaped guide bar 52 under the workbench 5, so as to achieve the guidance and limitation of the linear sliding of the workbench 5 on the base 21. The worktable 5 is provided with a pair of first linear limit assemblies 53 at each end. The first linear limit assemblies 53 at each end of the worktable 5 are adapted to be mounted on the same side of the base 21 as the linear limit guides 22. The first linear limit assemblies 53 adjust the linear sliding of the worktable 5 on the base 21, thereby improving the linearity of the precise sliding of the worktable 5 on the base 21. The first linear limit assemblies 53 at each end of the worktable 5 engage the limit guides 22 on the base 21 through the first linear limit assemblies 53 at each end of the worktable 5. Furthermore, the first linear limit assemblies 53 also act as anti-tilt limiters for the sliding of the worktable 5 on the base 21. By improving the structure of the base assembly 2 and the structure of the bottom surface of the worktable 5, the stability and linearity of the sliding of the worktable 5 on the base 21 are greatly improved. This effectively solves the problem that the worktable 5 and the base 21 in current milling machines or grinding machines generally use a conventional single set of slide rails and sliders as the sliding assembly, which often results in unstable sliding, poor sliding precision, and even tilting of the worktable 5.

[0069] The first inclined flat rail 31 and the second inclined flat rail 32 are respectively provided on the inclined crossbeam 3, and the first inclined flat rail 31 and the second inclined flat rail 32 are respectively provided with a first guide portion 33 and a second guide portion 34 on the side facing away from each other. The transverse moving box 7 can slide back and forth on the first inclined flat rail 31 and the second inclined flat rail 32 of the inclined crossbeam 3 along with the second screw assembly 72 and driven by the second servo motor 75. The second linear limiter assembly 71 is fixedly provided on the upper portion of the transverse moving box 7 and is adapted to be installed with the first inclined flat rail 31 on the upper portion of the inclined crossbeam 3, and a first two-dimensional limiter assembly 73 is provided on the lower portion of the transverse moving box 7 and is adapted to be installed with the second inclined flat rail 32 on the lower portion of the inclined crossbeam 3. The second linear limiter assembly 71 and the first two-dimensional limiter assembly 73 fixedly provided on the transverse moving box 7 can not only adjust the horizontal linear sliding of the transverse moving box 7, but also engage with the first inclined flat rail 31 to prevent the transverse moving box 7 from rocking back and forth during the sliding process. Furthermore, the third slider 733 of the first two-dimensional limiter assembly 73 can adjust the gap between the inclined crossbeam 3 and the transverse moving box 7 to ensure the linearity of the transverse moving box 7's precise sliding on the inclined crossbeam 3, thereby preventing the transverse moving box 7 from rocking left and right during the sliding process. The second inclined flat rail 32 can support the transverse moving box 7, so as to reduce the buckling and pulling of the second linear limit component 71 on the upper part of the transverse moving box 7 on the first inclined flat rail 31 in the inclined crossbeam 3, thereby avoiding the deformation of the first inclined flat rail 31 and affecting the accuracy of the transverse linear sliding of the transverse moving box 7. At the same time, it also reduces the lateral torsional influence of the transverse moving box 7 on the inclined crossbeam 3, so as to avoid the inclined crossbeam 3 being twisted by the gravity of the transverse moving box 7 and the components installed thereon, so that it can effectively solve the problem that the traditional milling machine or grinder is prone to twisting due to the influence of the gravity of the horizontal moving box and the components thereon, resulting in the horizontal moving box being prone to shaking during the horizontal sliding process, and reducing the straightness of the horizontal moving box during the horizontal sliding, thereby affecting the processing accuracy of the metal workpiece and reducing the quality of the finished product.

[0070] It also has a first longitudinal moving box 101 and a second longitudinal moving box on the front side of the transverse moving box 7 respectively, a third servo motor 102 is provided on the first longitudinal moving box 101, and a third screw rod assembly 103 is provided in the first longitudinal moving box 101. The upper end of the third screw rod assembly 103 is connected and installed with the third servo motor 102. When the third servo motor 102 rotates forward and reverse, the third screw rod assembly 103 can drive the first longitudinal moving box 101 to move up and down and slide. It is achieved by respectively providing a second two-dimensional limit assembly 104 and a third linear limit assembly 105 on both sides of the third screw rod assembly 103. The second two-dimensional limit assembly 104 and the third linear limit assembly 105 are respectively fixedly installed on the front side of the transverse moving box 7. The second two-dimensional limit assembly 104 and the third linear limit assembly 105 limit and adjust the first longitudinal moving box 101 to make a linear precise lifting and sliding movement on the front side of the transverse moving box 7. The third slider 733 in the second two-dimensional limit assembly 104 adjusts the gap between the first longitudinal moving box 101 and the transverse moving box 7 to avoid the first longitudinal moving box 101 from shaking left and right during the lifting and sliding process. It ensures the straightness of the first longitudinal moving box 101 making a precise sliding movement on the front side of the transverse moving box 7, thereby ensuring the straightness of the milling mechanism 8 making a precise sliding movement on the front side of the transverse moving box 7 through the first longitudinal sliding mechanism 10. The second longitudinal sliding mechanism 11 has the same working principle as the first longitudinal sliding mechanism 10. The third two-dimensional limit component 114 and the fourth linear limit component 115 of the second longitudinal sliding mechanism 11 limit and adjust the second longitudinal moving box 111 to make a linear precise lifting and sliding movement in front of the transverse moving box 7. The third slider 733 in the third two-dimensional limit component 114 adjusts the gap between the second longitudinal moving box 111 and the transverse moving box 7 to avoid the second longitudinal moving box 111 from shaking left and right during the lifting and sliding process. It ensures the straightness of the second longitudinal moving box 111 making a precise sliding movement in front of the transverse moving box 7, thereby ensuring the straightness of the grinding mechanism 9 making a precise sliding movement in front of the transverse moving box 7 through the second longitudinal sliding mechanism 11.

[0071] When the workpiece is moved below the milling mechanism 8 and the grinding mechanism 9 along with the worktable 5 and driven by the first servo motor 29, the milling mechanism 8 and the grinding mechanism 9 can be positioned directly above the metal workpiece to be processed after being moved laterally by the second screw assembly 72 and driven by the second servo motor 75 according to the processing requirements. When the milling mechanism 8 is lowered to the surface of the metal workpiece by the first longitudinal movable box 101 in the first longitudinal sliding mechanism 10 and the third screw assembly 103 and driven by the third servo motor 102, the first motor 82 in the milling mechanism 8 drives the tool to rotate via the main shaft to mill the surface of the metal workpiece. When the grinding mechanism 9 is lowered to the surface of the metal workpiece by the second longitudinal movable box 111 in the second longitudinal sliding mechanism 11 and the fourth screw assembly 113 and driven by the fourth servo motor 112, the second motor 92 in the grinding mechanism 9 drives the grinding head 93 to rotate via the third pulley assembly 94 to grind the surface of the metal workpiece.

[0072] It also provides a water spray assembly 12 on the grinding mechanism 9. The design of the water spray assembly 12 can reduce the temperature of the heat generated by the grinding mechanism 9 during the grinding process of the metal workpiece. The nozzle 124 is set to a flat shape so that the nozzle 124 can spray water over a wider range to meet the requirements of a wider cooling range for the metal workpiece, better cooling effect, faster cooling speed and shorter cooling time.

[0073] Its overall structural design not only realizes the integration of two different processes, milling and grinding of metal workpieces, on the same equipment, so as to solve the problem that the existing milling machine or grinder can only perform a single process on the metal workpiece, resulting in the need to lift the metal workpiece between the milling machine and the grinder when changing the process between the milling process and the grinding process, resulting in low production efficiency, high work intensity and high production cost. It also ensures that the sliding of the worktable 5 and the base 21 is stable, the linear sliding precision of the worktable 5 is high, and ensures the advantages of high processing efficiency, high processing precision, good processing effect, good quality of the finished product and high yield rate of the finished product. It also overcomes the problems of unstable sliding, poor sliding precision and occasional sliding tilt of the worktable 5 and the base 21 in the current milling machine or grinder, and overcomes the problem that the traditional milling machine or grinder is easily twisted because the gantry beam is affected by the gravity of the horizontal moving box and the components thereon, thereby reducing the processing precision of the grinding mechanism 9 and the milling mechanism 8 on the metal workpiece.

Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
