Description

Technical Field

[0001] This utility model relates to the field of CNC engraving machine technology, and in particular to a transmission control system for a five-axis CNC engraving machine. Background Technology

[0002] The shoe last is both the base of the shoe and its molding mold. It determines not only the shoe's shape and style but also its fit and ability to protect the foot. During shoe last production, a CNC last-cutting machine is used to process the last, ensuring it conforms to pre-defined standards for subsequent processing.

[0003] Current CNC last engraving machines are divided into three-axis drive and five-axis drive. Due to the large size range of the last blanks and the large amount of rough machining required, rough machining is necessary before finishing to remove most of the contour allowance. At the same time, a dovetail groove for finishing clamping is machined at the same opening of the shoe last. The existing last blank contour and dovetail groove milling are carried out in two processes. First, the shape of the last blank is milled by a three-axis CNC last engraving machine, and then the dovetail groove is milled on a dedicated same-end milling machine. When machining the dovetail groove, the angle of the B-axis rotation mechanism of the shoe last processing equipment needs to be adjusted to ensure that the machined dovetail groove meets the high-precision production standards.

[0004] However, the traditional CNC last engraving machine usually uses a gear rotation mechanism for adjustment. However, due to the existence of gear precision errors, it is easy to cause insurmountable synchronization and following errors, which in turn affects the processing quality of the shoe last. Utility Model Content

[0005] In order to overcome the technical defects mentioned in the background art, the purpose of this utility model is to provide a transmission control system for a five-axis CNC last engraving machine, which is not only simple and reasonable in structure design, but also can effectively improve the processing quality and precision of shoe lasts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A transmission control system for a five-axis CNC shoe last engraving machine includes a frame, a C-axis rotation mechanism disposed within the frame for clamping and fixing shoe last blanks, and a transmission mechanism slidably connected within the frame for controlling a milling cutter to process dovetail grooves in the shoe last blanks. The transmission mechanism includes a lateral movement component moving along the X-axis of the frame, a longitudinal movement component moving along the Y-axis of the frame, and an axial movement component moving along the Z-axis of the frame. The lateral and longitudinal movement components are slidably connected to the upper and lower sides of the axial movement component, respectively, and are perpendicular to the horizontal plane of the axial movement component. A B-axis transmission mechanism for adjusting the swing angle of the lateral movement component is movably connected to the bottom end of the axial movement component. The plane of the B-axis transmission mechanism is perpendicular to the plane of the Z-axis direction, and both ends of the B-axis transmission component are linked and cooperate with the lateral and axial movement components to form a triangular structure. The swing angle of the lateral movement component in the B-axis direction is controlled by controlling the extension length of the B-axis transmission component.

[0008] Preferably, the B-axis transmission assembly includes a transmission screw that moves along the B-axis direction, a nut seat that engages with the transmission screw, and hinge seats connected to one end of the transmission screw and the nut seat respectively. The transmission screw and the nut seat are connected via a screw drive engagement, and the transmission screw and the nut seat are obliquely positioned between the hinge seats. The hinge seats are fixed to the bottom ends of both the transverse movement assembly and the axial movement assembly. A movable sleeve is provided at the connection between the hinge seat and the transmission screw, and the movable sleeve is rotatably connected to the hinge seats.

[0009] Preferably, the C-axis rotation mechanism is based on the line connecting the clamping points of the shoe last head and the shoe last tail, and multiple C-axis rotation mechanisms are provided, which are arranged in a straight line and fixed on the frame.

[0010] Preferably, the C-axis rotation mechanism includes a last rotating seat for clamping and fixing shoe last blanks, a rotating shaft connected to the bottom end of the last rotating seat, and a last motor for driving the shoe last blanks on the last rotating seat to rotate around the C-axis. The arrangement direction of the last rotating seats is the X-axis direction. The rotating shaft is driven between the last rotating seat and the last motor along the rotation direction of the C-axis. The last motor is fixed inside the frame, and the output end of the last motor is drivenly connected to the rotating shaft.

[0011] Preferably, the lateral movement component includes a lateral guide plate, a lateral movement guide rail, and a dovetail milling cutter swing drive. The lateral guide plate is slidably connected to the bottom end of the axial movement component. The lateral movement guide rail is disposed on the lateral guide plate along the X-axis direction. The dovetail milling cutter swing drive is connected to the bottom end of the lateral guide plate, and the bottom end of the dovetail milling cutter swing drive is fixedly connected to a hinge seat.

[0012] Preferably, the dovetail groove end mill swing drive includes a transverse rotation shaft, a swing frame plate, a transverse drive motor, and a transverse drive cylinder. The transverse rotation shaft is fixed to the swing frame plate by multiple fixed seats, and the transverse rotation shaft and the transverse guide plate are in the same direction. The transverse drive motor is fixedly installed at the bottom end of the swing frame plate, and the output end of the transverse drive motor is connected to one end of the transverse drive cylinder through a pulley assembly. The transverse drive cylinders are arranged equidistantly on the swing frame plate, and the output end of the transverse drive cylinder is connected to a dovetail groove end mill.

[0013] Preferably, the longitudinal moving component includes a longitudinal moving plate, a profile milling cutter mounting bracket, and a profile milling cutter swing bracket. The longitudinal moving plate is slidably connected to the top of the axial moving component. Multiple profile milling cutter mounting brackets are provided, and the multiple profile milling cutter mounting brackets are arranged in a row along the X-axis direction on the front side of the profile milling cutter swing bracket. The profile milling cutter swing bracket is movably connected to the longitudinal moving plate.

[0014] Preferably, the axial movement assembly includes an axial movement frame, an axial transmission screw, and an axial drive motor. The upper and lower sides of the axial movement frame are provided with sliding guide rails that slide along the Y-axis. The sliding guide rails are slidably connected to a transverse guide plate and a longitudinal sliding plate, respectively. One end of the axial transmission screw is rotatably connected to the axial movement frame, and the other end is drivenly connected to the axial drive motor. The axial drive motor is fixedly installed on the top of the frame.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] Integrated processing: The two processes that originally required a three-axis CNC last engraving machine to mill the shape of the shoe last blank and a dedicated milling machine to mill the dovetail groove are combined into one. This avoids the problem of large repeated positioning errors between the two processes due to the lack of precise positioning surfaces in the shoe last structure, and greatly reduces the scrap rate. At the same time, it reduces the processing route and auxiliary time, and eliminates the need to transfer shoe last blanks between different machines. Rough processing and dovetail groove processing are completed in one go, which significantly improves processing efficiency.

[0017] Structural optimization: The B-axis transmission mechanism adopts a unique triangular structure. By changing the length of the third side through two fixed-length sides, the swing angle of the B-axis can be obtained, making the B-axis more rigid and ensuring higher precision and stability during processing, thus meeting the requirements of high-precision shoe last processing.

[0018] Multi-functional processing: The three-axis linkage of the lateral movement component, longitudinal movement component and axial movement component, combined with the C-axis rotation mechanism and B-axis transmission mechanism, enables the processing of shoe last blanks from all directions and multiple angles. Whether it is contour milling or dovetail groove processing, it can be completed with precision, adapting to the processing needs of shoe lasts of different sizes and shapes.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention provides a more detailed description of an embodiment of the transmission control system for a five-axis CNC engraving machine.

[0029] A transmission control system for a five-axis CNC shoe last engraving machine includes a frame 1, a C-axis rotation mechanism 2 disposed within the frame 1 for clamping and fixing shoe last blanks, and a transmission mechanism slidably connected within the frame 1 for controlling a milling cutter to process dovetail grooves in the shoe last blanks. The transmission mechanism includes a transverse movement component 3 that moves along the X-axis of the frame 1, a longitudinal movement component 4 that moves along the Y-axis of the frame 1, and an axial movement component 5 that moves along the Z-axis of the frame 1. The transverse movement component 3 and the longitudinal movement component 4 are slidably connected to the upper and lower parts of the axial movement component 5, respectively. On both sides, the lateral moving component 3 and the longitudinal moving component 4 are arranged perpendicularly to the horizontal plane of the axial moving component 5; the bottom end of the axial moving component 5 is movably connected to a B-axis transmission mechanism 6 for adjusting the swing angle of the lateral moving component 3; the plane where the B-axis transmission mechanism 6 is located is perpendicular to the plane in the Z-axis direction, and the two ends of the B-axis transmission component are respectively linked and cooperated with the lateral moving component 3 and the axial moving component 5 to form a triangular structure. The swing angle of the lateral moving component 3 in the B-axis direction is controlled by controlling the extension length of the B-axis transmission component.

[0030] Specifically, before fine machining the shoe last blank, a rough machining is required. Then, a clamping part for the next process is machined on this rough machining. This clamping part is a dovetail tenon structure. During the rough machining of the shoe last blank, the transverse movement component 3, the axial movement component 5, and the C-axis rotation mechanism 2 are controlled by three axes of linkage along the X-axis, Z-axis, and C-axis of the frame 1, respectively. During machining, the C-axis rotation mechanism 2 is responsible for controlling the shoe last blank to rotate along the C-axis. Then, when machining the dovetail tenon, the transverse movement component 3, the longitudinal movement component 4, and the axial movement component are used for three-axis linkage control along the X-axis, Y-axis, and Z-axis, respectively. The C-axis rotation mechanism 2 and the B-axis transmission mechanism 6 are only used for angular positioning and do not participate in linkage control. Furthermore, the B-axis transmission mechanism 6 can be used to control the swing angle of the lateral movement component 3. Since the swing angle is small, the B-axis transmission mechanism 6 is connected to the lateral movement component 3 and the axial movement component 5 in a triangular structure. By using two fixed-length sides of the B-axis transmission mechanism 6, the length of the third side only needs to be changed to obtain the swing angle of the B-axis, thereby obtaining greater B-axis rigidity and ensuring higher precision and stability during the processing, thus meeting the requirements of high-precision shoe last processing.

[0031] In this embodiment, the B-axis transmission assembly includes a transmission screw 61 that moves along the B-axis direction, a nut seat 62 that is connected to the transmission screw 61, and a hinge seat 63 that is connected to one end of the transmission screw 61 and the nut seat 62 respectively. The transmission screw 61 and the nut seat 62 are connected by a screw drive, and the transmission screw 61 and the nut seat 62 are obliquely arranged between the hinge seat 63. The hinge seat 63 is fixed to the bottom end of the transverse moving assembly 3 and the axial moving assembly 5 respectively, and a movable sleeve 64 is provided at the connection between the hinge seat 63 and the transmission screw 61. The movable sleeve 64 is rotatably connected to the hinge seat 63.

[0032] Specifically, when it is necessary to process dovetail grooves, the B-axis transmission mechanism plays a key role. The transmission screw 61 moves along the B-axis direction and engages with the nut seat 62 through screw transmission. Since the transmission screw 61 and the nut seat 62 are obliquely arranged between the hinge seat 63, and the hinge seat 63 is fixed at the bottom of the transverse moving component 3 and the axial moving component 5 respectively, by controlling the extension length of the transmission screw 61, the swing angle of the transverse moving component 3 in the B-axis direction can be precisely controlled, so that the dovetail groove milling cutter 335 can cut into the shoe last at a suitable angle to process the dovetail groove that meets the requirements, effectively ensuring the high precision and stability processing requirements of the shoe last.

[0033] In this embodiment, the C-axis rotation mechanism 2 uses the line connecting the clamping points of the shoe last head and the shoe last tail as the C-axis, and multiple C-axis rotation mechanisms 2 are provided, which are arranged in a straight line and fixed on the frame 1. The C-axis rotation mechanism 2 includes a shoe last rotating seat 21 for clamping and fixing the shoe last, a rotation shaft 22 connected to the bottom end of the shoe last rotating seat 21, and a shoe last motor 23 for driving the shoe last on the shoe last rotating seat 21 to rotate around the C-axis. The arrangement direction of the shoe last rotating seat 21 is the X-axis direction. The rotation shaft 22 is connected between the shoe last rotating seat 21 and the shoe last motor 23 along the rotation direction of the C-axis. The shoe last motor 23 is fixed inside the frame 1, and the output end of the shoe last motor 23 is connected to the rotation shaft 22.

[0034] Specifically, the last rotating base 21 includes a last head clamping tip, a last tail clamping seat, and a clamping hydraulic cylinder. The last tail clamping seat is connected to the clamping hydraulic cylinder and the clamping hydraulic cylinder provides clamping force. The last head clamping tip and the last tail clamping seat are arranged in a vertical direction. The shoe last blank is clamped between the last head clamping tip and the last tail clamping seat, and the last head is connected to the last head clamping tip. When clamping the shoe last blank, the last motor 23 drives the rotating shaft 22 to rotate, thereby driving the shoe last blank to rotate synchronously around the rotation direction of the rotating shaft 22, i.e., the C-axis, which facilitates the processing of the outer contour.

[0035] It is worth noting that a chip collection trough 7 and a chip discharge pipe are provided at the lower part of the frame 1, and the waste material in the shoe last processing process is discharged through the chip collection trough 7 and the chip discharge pipe.

[0036] In this embodiment, the transverse moving component 3 includes a transverse guide plate 31, a transverse moving guide rail 32, and a dovetail cutter 335 swing seat 33. The transverse guide plate 31 is slidably connected to the bottom end of the axial moving component 5. The transverse moving guide rail 32 is arranged on the transverse guide plate 31 along the X-axis direction. The dovetail cutter 335 swing seat 33 is connected to the bottom end of the transverse guide plate 31, and the bottom end of the dovetail cutter 335 swing seat 33 is fixedly connected to the hinge seat 63.

[0037] Specifically, the dovetail end mill 335 swing support frame 33 includes a transverse rotation shaft 331, a swing frame plate 332, a transverse drive motor 333, and a transverse drive cylinder 334. The transverse rotation shaft 331 is fixed to the swing frame plate 332 by setting multiple fixed seats, and the transverse rotation shaft 331 and the transverse guide plate 31 are set in the same direction. The transverse drive motor 333 is fixedly installed at the bottom end of the swing frame plate 332, and the output end of the transverse drive motor 333 is connected to one end of the transverse drive cylinder 334 through a pulley assembly. The transverse drive cylinders 334 are equidistantly arranged on the swing frame plate 332, and the dovetail end mill 335 is connected to the output end of the transverse drive cylinder 334.

[0038] In this embodiment, the longitudinal moving component 4 includes a longitudinal moving plate 41, a profile milling cutter mounting bracket 42, and a profile milling cutter swing bracket 43. The longitudinal moving plate 41 is slidably connected to the top of the axial moving component 5. Multiple profile milling cutter mounting brackets 42 are provided, and the multiple profile milling cutter mounting brackets 42 are arranged in a row along the X-axis direction on the front side of the profile milling cutter swing bracket 43. The profile milling cutter swing bracket 43 is movably connected to the longitudinal moving plate 41.

[0039] Specifically, the longitudinal moving component 4 moves along the Y-axis of the frame 1, the longitudinal moving plate 41 slides on the top of the axial moving component 5, and multiple contour milling cutter mounting brackets 42 are set for shoe last blanks at multiple workstations. The contour milling cutter mounting brackets 42 can be selected to install different contour milling cutters according to actual production needs, so as to be applicable to the processing of shoe last blanks of different sizes. Among them, the contour milling cutter swing seat 43 can be flexibly connected to the longitudinal moving plate 41, so as to meet the different contour milling needs when rough machining the shape of the shoe last blank.

[0040] In this embodiment, the axial movement assembly 5 includes an axial movement bracket 51, an axial transmission screw 61, and an axial drive motor 53. The axial movement bracket 51 has sliding guide rails on both its upper and lower sides, which are slidably connected to a transverse guide plate 31 and a longitudinal sliding plate, respectively. One end of the axial transmission screw 61 is rotatably connected to the axial movement bracket 51, and the other end is drively connected to the axial drive motor 53. The axial drive motor 53 is fixedly mounted on the top of the frame 1. By moving the axial movement assembly 5 along the Z-axis of the frame 1 and coordinating the transverse movement assembly 3 and the longitudinal movement assembly 4, three-axis linkage is achieved, enabling complex machining operations.

[0041] The working principle of this utility model:

[0042] In actual use of the transmission control system of this five-axis CNC last engraving machine, the shoe last blanks are first clamped and fixed by the C-axis rotation mechanism. The shoe last blanks are then clamped on the last rotating base 21, ensuring they face the same direction on the horizontal plane. The transmission control system of this invention is then activated, using the blank rotating motor to drive the last blanks on the last rotating base 21 to rotate around the C-axis. The axial movement component 5 drives the outer contour machining part on the longitudinal movement component 4 and the dovetail groove machining part on the transverse movement component 3 to move along the Z-axis. The outer contour machining part uses a contour milling cutter to process the last blanks on the multiple last rotating bases 21. The outer contour of the shoe last blank is processed. After the outer contour is processed, the contour milling cutter retracts and leaves the rotation range of the shoe last blank. Finally, the dovetail groove milling cutter 335 of the dovetail groove processing unit begins to feed. The dovetail groove processing unit uses the dovetail groove milling cutter 335 to process dovetail grooves on the shoe last blanks on multiple blank turntables 21. During the processing, the swing angle can also be controlled and adjusted by the B-axis transmission mechanism 6, so as to obtain greater B-axis rigidity and make the finishing accuracy of the shoe last blank higher.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
