Description

Technical Field

[0001] This utility model relates to the technical field of five-axis machining centers, and in particular to a composite five-axis machining center applied in the field of wood material processing. Background Technology

[0002] As is well known, in the existing woodworking field, multi-axis equipment is often used to process parts that cannot be processed by three-axis equipment. This processing method requires expensive machining centers, which directly leads to an increase in the cost of wood products and imposes a cost burden on manufacturers. In order to reduce the cost of woodworking, the industry usually processes semi-finished products on three-axis equipment and then transfers them to auxiliary equipment for the remaining processing. Although this processing method reduces equipment costs, the process is complex, and there is a risk of reduced product precision during the transfer of semi-finished products.

[0003] In view of the shortcomings of existing technologies, the urgent technical problem to be solved by manufacturers of processing equipment in this field is how to design a five-axis processing equipment that can achieve three-axis processing of products with relatively simple equipment, and can also be used for auxiliary processing with auxiliary five-axis equipment when processing needs expand, with the aim of completing fast and precise processing of multi-angle wood products on the same equipment. Summary of the Invention

[0004] To achieve the above objectives, this utility model develops a composite five-axis machining center, which achieves the formation of a three-dimensional basic machining architecture through a relatively simple structure, while setting up auxiliary five-axis machining equipment. It can realize the rapid machining of three-dimensional structures under normal machining conditions and realize five-axis machining under special requirements.

[0005] The technical solution adopted in this utility model is as follows:

[0007] A gantry frame is provided on the rear or front side of the machine tool. Multiple sets of transverse tracks are provided on the gantry frame. One set of transverse tracks is provided with a transverse drive motor and a transverse support plate. A vertical drive motor and a vertical guide rail are provided on the transverse support plate. A vertical support plate is provided on the upper part of the vertical guide rail. A vertical processing machine is provided on the vertical support plate.

[0008] One set of transverse tracks is equipped with a transverse fixing frame and an auxiliary transverse drive motor. An auxiliary fixing plate is provided on the front side of the auxiliary transverse drive motor. A vertical auxiliary guide rail and a vertical auxiliary drive motor are provided on the auxiliary fixing plate. A turntable drive motor, a turntable, and a vertical swing drive motor are provided on the drive end of the vertical auxiliary drive motor. The vertical swing drive motor drives the vertical turntable to connect with the five-axis machine head.

[0009] Each longitudinal moving pallet is equipped with multiple processing positions, and multiple processing positions can be driven to move longitudinally synchronously by a single longitudinal moving pallet.

[0010] The vertical support plate is equipped with several vertical machining units, each vertical machining unit is equipped with at least two vertical machining machines, each vertical machining machine in each vertical machining unit is independently driven, and the driving cutter head of each vertical machining machine in each vertical machining unit is set with unequal diameter.

[0011] The auxiliary working end is provided with a turntable base, a turntable drive motor and a turntable assembly are provided on the upper part of the turntable base, and a support frame is connected to the lower part of the turntable base; a vertical swing drive motor is provided on the support frame and connected to the vertical turntable, and the vertical turntable is connected to the five-axis machine head to realize the vertical swing drive of the five-axis machine head.

[0012] The gantry frame is equipped with a high-position transverse track and a low-position transverse track. The high-position transverse track protrudes to the front side of the low-position transverse track. The high-position transverse track is used to fix the transverse fixing frame and the auxiliary transverse drive motor. The low-position transverse track is used to fix the transverse drive motor and the transverse support plate.

[0013] The beneficial effects of this utility model are as follows: Through the above design, this utility model is equipped with a longitudinal moving track, a longitudinal moving pallet, and a longitudinal moving drive device on the machine base. Several processing positions are set on the longitudinal moving pallet. A gantry frame is set on the rear or front side of the machine base.

When a five-axis requirement is encountered, the entire five-axis machine head is transversely moved to the upper part of the processing position to achieve five-axis processing.

[0014] This utility model features a novel structural design. Without altering the original three-axis equipment, it expands to include a set of five-axis machining heads.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0022] As shown in the attached figure, a composite five-axis machining center includes a machine base 1, on which multiple sets of longitudinal traverse tracks 11 are provided. Each set of longitudinal traverse tracks 11 is provided with a longitudinal traverse support plate 12. The bottom of the longitudinal traverse support plate 12 is connected to the lead screw on the longitudinal traverse drive motor 15 to realize longitudinal traverse drive. Here, the longitudinal traverse drive motor 15 serves as the longitudinal traverse drive device. Each longitudinal traverse support plate 12 is provided with two machining positions 13. This utility model is equipped with a protective plate 14 for top protection in conjunction with the longitudinal traverse drive motor 15 and the lead screw.

[0023] The machine tool 1 is also equipped with a longitudinal positioning stake 16 as a positioning device for the longitudinal displacement of the longitudinal pallet 12, so as to prevent the longitudinal pallet 12 from moving beyond the limit.

[0024] This utility model also includes a gantry frame 2 at the rear of the machine base 1. The gantry frame 2 is equipped with multiple sets of transverse tracks. In this embodiment, the gantry frame 2 is equipped with a high-position transverse track 25 and a low-position transverse track 23. The high-position transverse track 25 is located on the front side of the top of the gantry frame. A top toothed belt 21 is also provided in conjunction with the transverse track 25. A transverse fixing frame 4 and an auxiliary transverse drive motor are mounted on the top toothed belt 21. In this embodiment, the auxiliary transverse drive motor is an auxiliary transverse drive motor 41 with a fixed drive gear. The front side of the auxiliary transverse drive motor... An auxiliary fixing plate 5 is fixed on the transverse fixing frame 4. The auxiliary fixing plate 5 is provided with a vertical auxiliary guide rail 51 and a vertical auxiliary drive motor 53. The lead screw of the vertical auxiliary drive motor 53 extends through the lead screw nut 54 and is fixed on the turntable seat 6. The upper part of the turntable seat 6 is provided with a turntable drive motor 61 and a turntable assembly 62. A support frame 64 is connected to the lower part of the turntable seat 60. A vertical swing drive motor 66 is provided on the support frame 64 and connected to a vertical turntable 65. The vertical turntable 65 is connected to a five-axis machine head 63 to realize the vertical swing drive of the five-axis machine head 63.

[0025] With the above structural setup, the auxiliary fixing plate 5 equipped with the five-axis machine head 63 can move laterally in front of the gantry 2 under the drive of the auxiliary transverse drive motor 41. The five-axis machine head 63 can move vertically under the drive of the vertical auxiliary drive motor 53, rotate in place under the drive of the turntable drive motor 61, and swing vertically under the drive of the vertical swing drive motor 66. Together with the longitudinal transfer plate 12, it drives the processing position 13 to move longitudinally, and finally realizes five-axis processing.

[0026] Because the five-axis requirement of this utility model is relatively small in actual operation, in order to meet the actual processing needs, the utility model is equipped with a horizontal drive motor 24 and a horizontal support plate 3 on the low-position horizontal track 23. The horizontal support plate 3 is equipped with a vertical drive motor 32 and a vertical guide rail 31. A vertical support plate 33 is provided on the upper part of the vertical guide rail 31. A machining machine track 34 is provided on the vertical support plate 33. Several vertical machining groups are set through the machining machine track 34. Each vertical machining group is equipped with at least two vertical machining machines. In this embodiment, the vertical machining group includes vertical machining machine I 36 and vertical machining machine II 37. Vertical machining machine I 36 and vertical machining machine II 37 are independently driven and are respectively connected to independent lifting cylinders 40. With the different sizes of cutting tools installed on vertical machining machine I 36 and vertical machining machine II 37, the equipment can achieve high-efficiency processing.

[0027] In conjunction with the above structural configuration, corresponding to each vertical support plate 33, two machining positions 13 are provided on each longitudinal moving support plate 12. The two machining positions 13 can be driven to move longitudinally synchronously by a single longitudinal moving support plate 12. With this design, each machining position 13 corresponds to a set of vertical machining machine I 36 and vertical machining machine II 37. When vertical machining machine I 36 and vertical machining machine II 37 are equipped with cutting tools of different sizes, simultaneous multi-part processing of the same woodwork can be achieved.

[0028] Furthermore, in this invention, the high-position transverse track 25 is used to fix the transverse fixing frame 4 and the auxiliary transverse drive motor 41; the low-position transverse track 23 is used to fix the transverse support plate 3. Because the front side of the high-position transverse track 25 protrudes to the front side of the low-position transverse track 23, the operation of the five-axis machine head 63 will not interfere with the running trajectory of the vertical machining machine I 36 and the vertical machining machine II 37.

[0029] This utility model features a novel structural design. Without altering the original three-axis equipment, it expands to include a set of five-axis machining heads. These five-axis machining heads can perform both three-dimensional and five-axis machining. They are low in cost and compensate for the functional deficiencies of existing technologies, making them an ideal composite five-axis machining center.
