Description

Technical Field

[0001] This utility model relates to, specifically, a single-spindle multi-turret CNC lathe. Background Technology

[0002] CNC machine tools are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] Current CNC machine tools are typically designed with a single spindle and a single turret. However, when machining some complex workpieces, the large number of tools required for machining the workpiece necessitates changing the tools before continuing machining. After the workpiece is finished, the tools need to be changed back, resulting in low overall machining efficiency. Furthermore, the frequent tool changes are cumbersome and labor-intensive.

[0004] While existing technologies also include dual-turret designs, these turrets are typically mounted in parallel on the machine tool base, and some even share the same servo feed mechanism. However, these designs result in a large overall machine tool structure and require significant space. Therefore, this paper proposes a single-spindle multi-turret CNC lathe. Utility Model Content

[0005] The purpose of this invention is to solve the above problems by proposing a single-spindle multi-turret CNC lathe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a single-spindle multi-turret CNC lathe, comprising a base and a spindle device mounted on the base; characterized in that it further comprises a slant bed, a flat bed, a slant bed turret mounted on the slant bed, a flat bed turret mounted on the flat bed, and a servo transmission system for driving the slant bed turret and the flat bed turret for feed transmission.

[0007] More preferably, the servo drive system includes a Y-axis drive system disposed on the slant bed and the flat bed, a slant bed slide plate slidably mounted on the slant bed and drivenly connected to the Y-axis drive system, a flat bed slide plate slidably mounted on the flat bed and drivenly connected to the X-axis drive system, and an X-axis drive system mounted on the slant bed slide plate and the flat bed slide plate.

[0008] Further preferably, it also includes a slant bed small slide that is slidably mounted on the slant bed large slide and driven by the X-axis transmission system, and a flat bed small slide that is slidably mounted on the flat bed large slide and driven by the X-axis transmission system.

[0009] More preferably, the turret of the slant bed is fixedly mounted on the slant bed small slide, and the turret of the flat bed is fixedly mounted on the flat bed small slide.

[0010] In a further preferred embodiment, both the X-axis drive system and the Y-axis drive system consist of a servo motor, a lead screw, a lead screw seat, and a nut seat.

[0011] A further preferred embodiment includes a clamping mechanism mounted on the spindle assembly.

[0012] Further preferably, it also includes a number of tool holders mounted on the slant bed turret and the flat bed turret, as well as cutting tools mounted on the tool holders.

[0013] The beneficial effects of this utility model are as follows: by setting a slant bed and a flat bed on the base, and setting a slant bed turret on the slant bed and a flat bed turret on the flat bed, a single spindle double turret design is realized. At the same time, the setting of the slant bed and the flat bed makes the structure of the entire machine tool reasonable and compact, and occupies little space.

[0014] By using a multi-turret setup, multiple different tools can be installed at once. When machining complex workpieces that require multiple tools, the turning and milling processes can be completed in one go without disassembling and replacing the tools during the machining process. This improves machining efficiency, reduces tool change time, and reduces labor intensity and machining complexity. Attached Figure Description

[0019] The following description, in conjunction with the accompanying drawings, further illustrates the single-spindle multi-turret CNC lathe of this utility model.

[0020] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] See Figures 1-3 As shown, a single-spindle multi-turret CNC lathe includes a base 1 and a spindle device 2 mounted on the base 1; it is characterized by further including a slant bed 3, a flat bed 4, a slant bed turret 31 mounted on the slant bed 3, a flat bed turret 41 mounted on the flat bed 4, and a servo transmission system for driving the slant bed turret 31 and the flat bed turret 41 to perform feed transmission.

[0023] By setting a slant bed 3 and a flat bed 4 on the base 1, and setting a slant bed turret 31 on the slant bed 3 and a flat bed turret 41 on the flat bed 4, a single spindle double turret design is achieved. At the same time, the setting of the slant bed 3 and the flat bed 4 makes the overall structure of the machine tool reasonable and compact, and occupies little space.

[0024] With the multi-turret setup, multiple different tools can be installed at once. When machining complex workpieces that require multiple tools, the machining of the workpiece can be completed in one go without disassembling and replacing the tools during the machining process. This improves machining efficiency, reduces tool change time, and reduces labor intensity and machining complexity.

[0025] Furthermore, the multi-turret configuration allows for the processing of different workpieces, eliminating the need to change the required tools depending on the specific workpiece being processed.

[0026] In one embodiment, the servo drive system includes a Y-axis drive system mounted on the slant bed 3 and the flat bed 4, a slant bed slide plate 5 slidably mounted on the slant bed 3 and drivenly connected to the Y-axis drive system, a flat bed slide plate 6 slidably mounted on the flat bed 4 and drivenly connected to the X-axis drive system, and an X-axis drive system mounted on the slant bed slide plate 5 and the flat bed slide plate 6.

[0027] When the slant bed large slide 5 moves along the slant bed 3, it is driven to move along the slant bed 3 by the Y-axis servo transmission system set on the slant bed 3;

[0028] When the flatbed large slide 6 moves along the Y-axis, it is driven to move along the flatbed 4 by the Y-axis servo transmission system set on the flatbed 4.

[0029] In one embodiment, it also includes a slant bed small carriage 51 that is slidably mounted on the slant bed large carriage 5 and driven by the X-axis transmission system, and a flat bed small carriage 61 that is slidably mounted on the flat bed large carriage 6 and driven by the X-axis transmission system.

[0030] When the slant bed small slide 51 moves along the X-axis, it is driven to move along the X-axis by the X-axis servo transmission system set on the slant bed large slide 5;

[0031] When the flatbed small slide 61 moves along the X-axis, it is driven by the X-axis servo transmission system set on the flatbed large slide 6.

[0032] In one embodiment, the slant bed turret 31 is fixedly mounted on the slant bed small slide 51, and the flat bed turret 41 is fixedly mounted on the flat bed small slide 61.

[0033] In one embodiment, both the X-axis transmission system and the Y-axis transmission system are composed of a servo motor 7, a lead screw 71, a lead screw seat 72, and a nut seat 73. During feeding, the servo motor 7 drives the lead screw 71 to rotate. During the rotation, the lead screw 71 moves the support plate that is fixedly connected to the nut seat 73 by cooperating with the nut seat 73.

[0034] In one embodiment, a clamping mechanism 8 is also included, which is mounted on the spindle assembly 2.

[0035] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
