[0020] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] The embodiment of the present invention provides a precision five-axis grinding machine, such as Figures 1 to 8 As shown, it includes a first moving assembly 10, a second moving assembly 20, and a third moving assembly 30 which are vertically distributed to each other. The first moving assembly 10 is connected to the second moving assembly 20. The first moving assembly 10 is provided with a clamping assembly 60 for clamping and rotating a workpiece 400. The third moving assembly 30 is provided with a driving assembly 40, which includes a driving base 41 connected to the third moving assembly 30, a processing spindle 51 being slidably connected in the driving base 41, a driving motor 42 being installed at one end of the driving base 41, an eccentric piece 43 being installed on the output shaft of the driving motor 42, and a connecting rod 44 being hingedly connected to the eccentric piece 43 for driving the processing spindle 51 to reciprocate; A grinding wheel 52 for grinding the workpiece 400 is installed on the machining spindle 51. The second moving assembly 20 is used to drive the first moving assembly 10 to move along the Y-axis direction. The first moving assembly 10 is used to drive the clamping assembly 60 to move along the X-axis direction. The third moving assembly 30 is used to drive the driving assembly 40 to move along the Z-axis direction. In this embodiment, the first moving assembly 10, the second moving assembly 20, and the third moving assembly 30 are all driven by motors and are linear drive structures well-known to those skilled in the art, which will not be elaborated here.

[0024] It should be noted that a precision five-axis grinding machine provided by the present invention can achieve precise grinding of complex shapes by flexibly moving along the X, Y, and Z axes and combining the clamping and rotation of the workpiece 400 by the clamping assembly 60, improving the machining accuracy and quality of the workpiece 400. Since the driving assembly 40 plays a driving role, the reciprocating motion of the machining spindle 51 is smoother and more stable, and the control of the machining depth and motion trajectory is more precise, thus being able to meet different machining requirements. By reasonably arranging each component, the overall stability is improved, reducing the vibration and instability that may occur during the machining process, which helps to extend the service life of the equipment. Since the clamping assembly 60 has both clamping and rotation functions, it can be used for different types of grinding and machining processes, increasing the versatility of the equipment. This grinding machine is suitable for machining workpieces 400 of different specifications and materials, enhancing the universality of the equipment. Therefore, the present invention solves the technical problem of insufficient grinding accuracy of the workpiece 400 in the prior art five-axis grinding machine.

[0025] As Figures 3 to 5 shown, the eccentric member 43 includes a first eccentric block 431 fixedly connected to the output shaft of the driving motor 42. The first eccentric block 431 is slidably connected with a second eccentric block 432. One end of the connecting rod 44 far from the machining spindle 51 is hinged to the second eccentric block 432. In this embodiment, the second eccentric block 432 is inclined. The first eccentric block 431 is threadedly connected with a first adjusting rod 45 and a second adjusting rod 46 arranged oppositely. Both the first adjusting rod 45 and the second adjusting rod 46 are used to adjust the installation position of the second eccentric block 432 on the first eccentric block 431.

[0026] Specifically, when the driving motor 42 moves, it drives the first eccentric block 431 and the second eccentric block 432 to rotate. Through the motion transmission of the connecting rod 44, it drives the machining spindle 51 to perform a reciprocating linear motion, enabling the grinding wheel 52 to form the required machining path on the surface of the workpiece 400 and improving the machining accuracy of the workpiece 400.

[0027] It should be noted that when adjusting the position of the second eccentric block 432, by loosening the first adjusting rod 45 and tightening the second adjusting rod 46, the hinge point of the connecting rod 44 and the second eccentric block 432 is moved away from the rotation center of the first eccentric block 431, thereby increasing the movement distance of the driving main shaft; conversely, by tightening the first adjusting rod 45 and loosening the second adjusting rod 46, the hinge point of the connecting rod 44 and the second eccentric block 432 approaches the rotation center of the first eccentric block 431, thereby reducing the movement distance of the driving main shaft, thus realizing the adjustable reciprocating distance of the driving main shaft.

[0028] As Figure 5 shown, the second eccentric block 432 is provided with a first adjusting groove 4321 and a second adjusting groove 4322 at intervals. The first adjusting rod 45 is embedded in the first adjusting groove 4321 and abuts against the inner wall of the first adjusting groove 4321, and the second adjusting rod 46 is embedded in the second adjusting groove 4322 and abuts against the inner wall of the second adjusting groove 4322; The first eccentric block 431 is provided with a first inclined surface 4311, and the second eccentric block 432 is provided with a second inclined surface 4323 corresponding to the first inclined surface 4311.

[0029] It should be noted that through the first adjusting groove 4321 and the second adjusting groove 4322 arranged at intervals, it is convenient to accommodate the first adjusting rod 45 and the second adjusting rod 46, and the specific position of the second eccentric block 432 on the first eccentric block 431 is adjusted, thereby changing the eccentricity and running track of the second eccentric block 432, and enhancing the adaptability of the equipment under different processing conditions. Through the arrangement of the first inclined surface 4311 and the second inclined surface 4323, the contact between the first eccentric block 431 and the second eccentric block 432 is increased, the looseness during the movement is reduced, thereby improving the stability of the mechanical system and reducing the failure rate.

[0030] As Figures 2 to 5 shown, a guide rail 47 and a sealing box 49 for covering the guide rail 47 are installed in the driving base 41. A slider 410 is slidably connected to the guide rail 47, and a transfer plate 411 is fixedly connected to the slider 410. A moving plate 511 fixedly connected to the transfer plate 411 is sleeved on the processing main shaft 51; One end of the connecting rod 44 far from the eccentric member 43 is hinged to the moving plate 511, and joints 48 for realizing the inlet and outlet of liquid are installed at both ends of the sealing box 49. In the specific implementation process, through the arrangement of the two joints 48, oil or water can be injected into the sealing box 49. After the driving motor 42 moves, it drives the eccentric member 43 to perform a rotational motion, so that the connecting rod 44 drives the moving plate 511 to move, thereby realizing the reciprocating linear motion of the processing main shaft 51; at the same time, the moving plate 511 drives the transfer plate 411 to move. Since the slider 410 is fixedly connected to the transfer plate 411, the transfer plate 411 drives the slider 410 to perform a reciprocating linear motion on the guide rail 47.

[0031] It should be noted that the guide rail 47 provides an accurate movement path for the slider 410. Combining the use of the moving plate 511 and the adapter plate 411 enhances the accuracy and stability of the driving assembly 40, which helps to achieve high-quality processing effects. Through the setting of the joint 48, the lubrication and cooling conditions can be quickly adjusted according to the processing needs, enhancing the adaptability of the equipment. The lubricating fluid (such as oil or water) in the seal box 49 can effectively reduce the frictional heat between the slider 410 and the guide rail 47, thereby reducing equipment damage caused by overheating and maintaining long-term efficient operation.

[0032] Such as Figure 7 and Figure 8 As shown, a reading head 412 is installed on one side of the adapter plate 411, and a grating scale 413 corresponding to the reading head 412 is installed on the side wall of the seal box 49; A first sealing ring 414 and a second sealing ring 415 are installed in the seal box 49. The first sealing ring 414 abuts against the inner wall of the driving base 41, and the second sealing ring 415 abuts against the inner wall of the adapter plate 411. In this embodiment, the reading head 412 is a well-known structure to those skilled in the art and will not be elaborated here.

[0033] It should be noted that through the cooperation of the reading head 412 and the grating scale 413, the movement position of the adapter plate 411 is monitored in real time. When the adapter plate 411 moves, the reading head 412 can measure its precise position by reading the code on the grating scale 413, providing feedback information for the precision machining of the workpiece 400, enabling high-precision control, and improving the machining accuracy of the five-axis grinding machine. Through the sealing effect of the first sealing ring 414 and the second sealing ring 415, liquid leakage and dust entry are reduced, thereby reducing the risk of wear and failure and enhancing the stability and reliability of the equipment.

[0034] Such as Figure 7 and Figure 8 As shown, the projected area of the adapter plate 411 is larger than the projected area of the seal box 49. A limiting table 416 is fixedly installed in the driving base 41. The limiting table 416 is provided with a limiting groove 4161 in a penetrating manner. A limiting plate 417 that is slidably matched with the limiting groove 4161 is fixedly installed at one end of the moving plate 511 away from the connecting rod 44.

[0035] It should be noted that since the projected area of the adapter plate 411 is larger than that of the sealing box 49, during the reciprocating linear motion of the adapter plate 411, the sealing box 49 is effectively sealed to prevent the liquid in the sealing box 49 from flowing out. Through the joint work of the limiting groove 4161 and the limiting plate 417, it is ensured that the moving plate 511 will not exceed the restricted range. If the moving plate 511 moves excessively due to a malfunction or other reasons, the limiting plate 417 will limit the moving trajectory of the moving plate 511 to prevent damage to the equipment.

[0036] As Figures 2 to 5 shown, a first cover plate 418 and a second cover plate 419 are installed on the driving base 41. A first opening 4181 for accommodating the reciprocating movement of the machining spindle 51 is provided on the first cover plate 418, and a detection assembly 90 located inside the second cover plate 419 is installed on the driving base 41; A second opening 4191 for accommodating the detection activities of the detection assembly 90 is provided at the bottom of the second cover plate 419. A sealing motor 70 is installed on one side of the second cover plate 419, and a sealing plate 80 for sealing the second opening 4191 is installed on the output shaft of the sealing motor 70.

[0037] Specifically, when the detection assembly 90 is working, the clamping assembly 60 makes a position avoidance. The sealing plate 80 is driven to rotate by the sealing motor 70, so that the sealing plate 80 moves away from the second opening 4191; then, the detection assembly 90 can achieve the detection function.

[0038] It should be noted that when detection is required, the sealing motor 70 is started to drive the sealing plate 80 to rotate. Through the rotation operation, the sealing plate 80 will move away from the second opening 4191 to ensure that the detection assembly 90 can perform the detection action through the second opening 4191. When the detection assembly 90 is working, the clamping assembly 60 makes a position avoidance to ensure that the clamping assembly 60 will not interfere with the detection operation of the detection assembly 90. Integrating the detection assembly 90 into the driving base 41 reduces the external space requirement, improves the compactness of the five-axis grinding machine, and also improves the maintainability of the five-axis grinding machine.

[0039] As Figures 2 to 5 shown, the number of the second openings 4191 is set to two. The detection assembly 90 includes a detection base 91 fixedly connected to the driving base 41. An expansion member 92, a detection camera 93 and a detection probe 94 are arranged on the detection base 91. The expansion member 92 is used to drive the detection probe 94 to perform telescopic movement; The number of the second openings 4191 is set to two. The detection camera 93 corresponds to one of the second openings 4191, and the detection probe 94 corresponds to the other second opening 4191. In this embodiment, the expansion member 92 is a telescopic cylinder or a telescopic motor, and the expansion member 92 can drive the detection camera 93 and the detection probe 94 to perform synchronous telescopic movement.

[0040] It should be noted that when the system needs to perform visual inspection, the inspection camera 93 observes through the first second opening 4191 to provide an image feedback of the state of the workpiece 400. When physical contact detection is required, the telescopic member 92 drives the inspection probe 94 to perform telescopic movement, so that the inspection probe 94 extends out of the other second opening 4191 and can perform measurements at different contact points. Through the setting of the two second openings 4191, different types of inspections can be carried out simultaneously, avoiding repeated operations in terms of time and space, thereby improving the overall working efficiency. Through the use and cooperation of the inspection probe 94 and the inspection camera 93, high-precision inspection and monitoring can be achieved, providing multi-level feedback information to ensure the accuracy and reliability of the machining process.

[0041] As Figure 1 and Figure 6 shown, the clamping assembly 60 includes a clamping table 61. A rotary cylinder 62 and a first ejector pin 63 are distributed oppositely on the clamping table 61. The rotary cylinder 62 is slidably connected to the clamping table 61. Clamping cylinders 64 are installed on both sides of the clamping table 61. A connecting rod 65 for driving the rotary cylinder 62 to perform telescopic movement is fixedly connected to the telescopic rod of the clamping cylinder 64; in this embodiment, the clamping cylinder 64 drives the rotary cylinder 62 to move along the C-axis direction; A second ejector pin 66 corresponding to the first ejector pin 63 is installed on the rotary cylinder 62. Both the first ejector pin 63 and the second ejector pin 66 are used to clamp the workpiece 400. The rotary cylinder 62 is used to drive the second ejector pin 66 to perform a rotary movement, so that the second ejector pin 66 drives the workpiece 400 to perform a rotary movement. In this embodiment, the first ejector pin 63 is fixed on the clamping table 61, and a light source 67 for providing light to the detection assembly 90 is installed on the clamping table 61. The first ejector pin 63 and the second ejector pin 66 are located on the same straight line, and the rotary cylinder 62 is used to drive the second ejector pin 66 to perform a rotary movement along the A-axis direction.

[0042] It should be noted that the clamping cylinder 64 drives the rotary cylinder 62 to move along the C-axis direction, so that the second ejector pin 66 approaches the first ejector pin 63, and then the workpiece 400 is clamped by the first ejector pin 63 and the second ejector pin 66; the rotary cylinder 62 drives the second ejector pin 66 to perform a rotary movement along the A-axis direction, so that the second ejector pin 66 drives the workpiece 400 to perform a rotary movement. Combined with the reciprocating linear movement of the machining spindle 51, the grinding wheel 52 grinds multiple surfaces of the workpiece 400. Through the use of the light source 67, it is ensured that the detection assembly 90 can operate under good lighting conditions, thereby improving the detection quality and efficiency of the workpiece 400.

[0043] As Figure 1As shown in the figure, a first marble base 100 is installed at the bottom of the second moving component 20. A steel frame base 200 is fixedly installed at the bottom of the first marble base 100. One end of the first marble base 100 is vertically and fixedly installed with a second marble base 300. The third moving component 30 is installed on the second marble base 300.

[0044] It should be noted that both the first marble base 100 and the second marble base 300 are made of marble material. Because they have good rigidity and stability, they can effectively suppress vibration and transmission, ensure a stable working environment during high-precision grinding, reduce machining errors caused by vibration, and improve the machining performance and reliability of the entire grinding machine. The steel frame base 200 at the bottom provides strong support for the entire five-axis grinding machine. The first marble base 100 and the second marble base 300 fixedly installed above it form a layered structure, which can effectively disperse the loads caused by the movement of the first moving component 10, the second moving component 20, and the third moving component 30.

[0045] Working principle: A precision five-axis grinding machine provided by the present invention can achieve precise grinding of complex shapes by flexibly moving the X, Y, and Z axes and combining the clamping component 60 to clamp and rotate the workpiece 400, improving the machining accuracy and quality of the workpiece 400. Since the driving component 40 plays a driving role, the reciprocating movement of the machining spindle 51 is smoother and more stable, and the control of the machining depth and movement trajectory is more precise, so as to meet different machining requirements. By reasonably arranging each component, the overall stability is improved, reducing the vibration and instability that may occur during the machining process, and helping to extend the service life of the equipment. Since the clamping component 60 has both clamping and rotating functions, it can be used for different types of grinding and machining processes, increasing the versatility of the equipment. This grinding machine is suitable for machining workpieces 400 of different specifications and materials, enhancing the versatility of the equipment. Therefore, the present invention solves the technical problem of insufficient grinding accuracy of workpieces 400 in existing five-axis grinding machines.

[0046] The above is the case. The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
