Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a dual-station machine tool and its base. Background Technology

[0002] With the continuous advancement of science and technology and the development of social production, people have placed increasingly higher demands on the quality and productivity of mechanical products. Automation of the machining process is an effective way to achieve these requirements and has been widely adopted. However, excessive vibration during machine tool operation can damage the internal structure of the machine, reduce work efficiency, and cause certain adverse effects. Furthermore, in dual-station machine tools, vibrations generated at one station can affect the other, leading to defects such as uneven workpiece surfaces and poor precision.

[0003] CN212823903U discloses a dual-station machine tool base, comprising a long strip-shaped main body and two side sections located on both sides of the main body and symmetrically opposite to the main body. The line connecting the two side sections is perpendicular to the length direction of the main body. The main body and the side sections are integrally fixed. The bottom of both the main body and the side sections are provided with crisscrossing partitions, which are integrally fixed into a mesh. The surfaces of the partitions are all vertical, and adjacent partitions form empty slots. Each partition has a weight-reducing groove connecting adjacent empty slots, located in the middle of the slot wall. A base plate is fixed to the bottom of each partition, and multiple weight-reducing grooves are provided through the surface of the base plate, each corresponding to an empty slot. While this machine tool base has the advantages of light weight and high structural strength, its main structure is still a traditional grid type. In actual operation, vibrations from one station will be directly transmitted to the other station along the partitions. Obviously, this structure will still cause the two stations to affect each other due to vibrations.

[0004] Based on this, the technical problem to be solved in this case is: how to solve the problem of defects in workpieces caused by the mutual influence between the two stations in existing dual-station machine tools. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a dual-station machine tool base. The structure of this base reduces the mutual interference between the two stations. Furthermore, a dual-station machine tool using this base is provided, which offers advantages such as higher machining accuracy and better product quality.

[0006] The technical solution of this utility model is:

[0007] A dual-station machine tool base includes a base body, which is composed of three parts: a first station, a vibration filtering area, and a second station. The first station and the second station are symmetrically arranged on both sides of the vibration filtering area. The first station has multiple first slots arranged in a matrix. The bottom of the second station has multiple second slots arranged in a matrix. The bottom of the vibration filtering area has multiple third slots arranged in a matrix. The first and third slots are staggered, and the second and third slots are staggered, with the third slots located between adjacent first slots and / or between adjacent first slots to reduce the vibration impact between the first station and the second station.

[0008] In the aforementioned dual-station machine tool base, the first station and the second station are mirror images; the bottom of both the first station and the second station are provided with crisscrossing partitions to form multiple matrix arrangements of the first slot and the second slot; the bottom of the vibration filtering area is provided with crisscrossing reinforcing ribs to form multiple matrix arrangements of the third slot.

[0009] In the aforementioned dual-station machine tool base, the partition plate is provided with a first through hole; the reinforcing rib is provided with a second through hole.

[0010] In the aforementioned dual-station machine tool base, the upper surface of the base is inclined to the horizontal plane and is provided with a chip removal groove.

[0011] In addition, this application also discloses a dual-station machine tool, including the above-mentioned dual-station machine tool base, and further including a first column and a first worktable disposed at the first station, and a second column and a second worktable disposed at the second station; the first column is provided with a first spindle that moves up and down along the Z-axis; the second column is provided with a second spindle that moves up and down along the Z-axis.

[0012] In the aforementioned dual-station machine tool, the first station is further provided with a first transverse drive assembly that moves left and right along the X-axis and a first longitudinal drive assembly that moves back and forth along the Y-axis; the first worktable is slidably connected to the first transverse drive assembly, and the first transverse drive assembly is slidably connected to the first longitudinal drive assembly.

[0013] The second workstation is also provided with a second transverse drive assembly that moves left and right along the X-axis and a second longitudinal drive assembly that moves back and forth along the Y-axis; the second worktable is slidably connected to the second transverse drive assembly, and the second transverse drive assembly is slidably connected to the second longitudinal drive assembly.

[0014] In the aforementioned dual-station machine tool, the first transverse drive assembly, the first longitudinal drive assembly, the second transverse drive assembly, and the second longitudinal drive assembly are all motor lead screw sliding assemblies.

[0015] In the aforementioned dual-station machine tool, the first column is equipped with a first automatic tool changer assembly; the second column is equipped with a second automatic tool changer assembly.

[0016] The aforementioned dual-station machine tool also includes a control unit for regulating the machining actions of the first station and the machining actions of the second station.

[0017] In the aforementioned dual-station machine tools, the dual-station machine tools have a symmetrical structure.

[0018] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0019] The base structure of this utility model symmetrically arranges the first and second workstations on both sides of the vibration filtering area, so that the vibrations generated by both must pass through the vibration filtering area. In practical applications, when the vibration is transmitted from the first slot of the first workstation to the third slot of the vibration filtering area, compared with the traditional structure, the third slot, which is offset from the first slot, can greatly reduce the vibration and stress generated by the first workstation before being transmitted to the second workstation (similarly, the vibration generated by the second workstation can also be reduced before being transmitted to the first workstation). This effectively disperses the stress applied to the machine tool, reduces local stress concentration, and extends the service life of the machine tool.

[0020] Furthermore, the dual-station machine tool provided by this utility model has independent drives for the two spindles, which can reduce mutual influence between the two stations while improving production efficiency and reducing floor space. At the same time, the axial adjustments of each station can be controlled independently, enabling not only synchronous control of the same process, but also linkage control of different processes.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1-6 A dual-station machine tool base includes a base body, which is composed of three parts: a first station 1, a vibration filtering area 3, and a second station 2. The first station 1 and the second station 2 are symmetrically arranged on both sides of the vibration filtering area 3. The first station 1 has multiple first slots A arranged in a matrix. The bottom of the second station 2 has multiple second slots C arranged in a matrix. The bottom of the vibration filtering area 3 has multiple third slots B arranged in a matrix. The first slots A and the third slots B are arranged alternately, and the second slots C and the third slots B are arranged alternately. The third slots B are located between adjacent first slots A and / or between adjacent first slots A above and below, so as to reduce the vibration influence between the first station 1 and the second station 2.

[0034] In this embodiment, the first station 1 and the second station 2 are mirror images. Therefore, in the following text, for the sake of simplicity, the first station 1 will be described in detail. Under this design, the first slot A and the second slot C are mirror images of each other on both sides of the vibration filtering area 3, and the third slot B is located between the adjacent first slots A. The specific function of the third slot B is detailed below. It should be noted that in other embodiments, the first slot A and the second slot C may be non-mirror images and the first slot A and the second slot C may be staggered.

[0035] The base structure of this embodiment symmetrically arranges the first station 1 and the second station 2 on both sides of the vibration filtering area 3, so that the vibration generated by both must pass through the vibration filtering area 3. In practical applications, when the vibration is transmitted from the first slot A of the first station 1 to the third slot B of the vibration filtering area 3, compared with the traditional structure, the third slot B, which is offset from the first slot A, can greatly reduce the vibration and stress generated by the first station 1, and then transmit it to the second station 2 (similarly, the vibration generated by the second station 2 can also be reduced before being transmitted to the first station 1). This effectively disperses the stress applied to the machine tool, reduces local stress concentration, and extends the service life of the machine tool.

[0036] Specifically, the bottom of the first station 1 and the second station 2 are provided with crisscrossing partitions 101 to form multiple matrix arrangements of the first empty slot A and the second empty slot C; the bottom of the vibration filtering area 3 is provided with crisscrossing reinforcing ribs 201 to form multiple matrix arrangements of the third empty slot B.

[0037] Under the above design, as shown in the attached drawings, the vibration generated by the machine tool will be transmitted from the partition 101 to the third slot B, and then distributed to both sides of the reinforcing rib 201 through the third slot B and continue to be transmitted. During this process, the vibration will be greatly reduced by the structure of the third slot B, thereby reducing the impact on the other station.

[0038] It should be noted that the multiple first slots A in this embodiment are not entirely identical. Some first slots A are large squares, while others are small rectangles. This difference arises from the issue of floor space. In practical applications, we designed the space between the first slots A and the distance between the first slot A and the third slot B to be equal. This design further prevents stress concentration at a single point on the base. Similarly, the multiple third slots B are also not entirely identical.

[0039] More specifically, the partition plate 101 is provided with a first through hole 110 connecting the adjacent first empty slot A; the reinforcing rib 201 is provided with a second through hole 210 connecting the first empty slot A and the third empty slot B or connecting the adjacent third empty slot B.

[0040] In this design, both the first through hole 110 and the second through hole 210 are designed to reduce weight. Under the premise of meeting the overall connection strength, the weight of the machine tool base is reduced as much as possible, which not only saves costs but also facilitates transportation.

[0041] As a preferred embodiment, in order to prevent cutting waste from accumulating on the machine tool and affecting operation, the upper end surface of the base is inclined to the horizontal plane and is provided with a chip removal groove 310.

[0042] A dual-station machine tool includes the aforementioned dual-station machine tool base, and further includes a first column 11 and a first worktable 12 disposed at a first station 1, and a second column 21 and a second worktable 22 disposed at a second station 2. A first spindle 111, which moves vertically along the Z-axis, is mounted on the first column 11; a second spindle 211, which also moves vertically along the Z-axis, is mounted on the second column 21. It should be further noted that the machine tool in this embodiment is a drilling and tapping machine tool. In practical applications, it also includes a control unit for regulating the machining actions of the first station 1 and the second station 2.

[0043] In this embodiment, the first workstation 1 is further provided with a first transverse drive assembly 112 that moves left and right along the X-axis and a first longitudinal drive assembly 113 that moves back and forth along the Y-axis; the first worktable 12 is slidably connected to the first transverse drive assembly 112, and the first transverse drive assembly 112 is slidably connected to the first longitudinal drive assembly 113.

[0044] The second workstation 2 is also provided with a second transverse drive assembly 212 that moves left and right along the X-axis and a second longitudinal drive assembly 213 that moves back and forth along the Y-axis; the second worktable 22 is slidably connected to the second transverse drive assembly 212, and the second transverse drive assembly 212 is slidably connected to the second longitudinal drive assembly 213.

[0045] Under the above design, the processes of the first station 1 and the second station 2 can operate independently of each other, with less interference from vibrations. More preferably, through the setting of the control program, the actions of the first station 1 and the second station 2 can achieve a variety of combination modes. Through high-level and flexible dual-channel system control, dual-station independent control and compensation, independent dual tool magazine, multi-system program management system and other high-level functions help to improve productivity. In addition, the action sequence of the first station 1 and the second station 2 can be differentiated according to the actual processing. For example, when the first station 1 is drilling continuously, the second station 2 is exactly in the sequence that needs to change positions, thereby avoiding the vibrations caused by the two stations drilling at the same time from affecting the processing quality.

[0046] As a preferred embodiment, the first lateral drive assembly 112, the first longitudinal drive assembly 113, the second lateral drive assembly 212, and the second longitudinal drive assembly 213 are all motor lead screw sliding assemblies. It should be noted that any modifications to other drive structures in this technical field without creative effort by those skilled in the art should be within the scope of protection of this embodiment.

[0047] As a further preferred embodiment, the first column 11 is provided with a first automatic tool changer 114; the second column 21 is provided with a second automatic tool changer 214. With this design, tools can be changed quickly during machining, reducing manual tool changing time and thus improving production efficiency. Furthermore, it reduces manual intervention, accurately positions the tool, and ensures consistent tool changing, thereby improving machining accuracy and quality.

[0048] As a further preferred embodiment, the dual-station machine tool has a symmetrical structure. A symmetrical structure not only helps reduce vibration during machining, as vibration sources can cancel each other out through a symmetrical layout, thereby improving machining accuracy and surface quality, but also evenly distributes the weight of each component of the machine tool, reducing tilting and deformation caused by a shift in the center of gravity, and improving the stability of the machine tool.

[0049] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
