Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a high-precision CNC double-tool post vertical turning center. Background Technology

[0002] A CNC lathe is an automated machine tool controlled by a digital program. Through a pre-programmed machining program, a CNC lathe can automatically complete the precision cutting of metal or non-metal materials. Its control system can analyze digital instructions and drive the tool and workpiece to move along the trajectory set in the program to realize the machining of complex shapes.

[0003] For example, the Chinese authorized patent with publication number CN218194016U (A CNC Lathe) includes a CNC lathe body, on which a collection box for collecting waste chips is detachably connected. The collection box is fixed to the CNC lathe by a limiting structure. When the CNC lathe body is machining the rotor, the waste chips generated during machining fall into the collection box. After machining is completed, the waste chips can be directly transported through the collection box to the waste chip cleaning area for cleaning. Thus, the collection box collects the waste chips generated during machining of the CNC lathe body, avoiding a large accumulation of waste chips at the bottom of the CNC lathe body, and facilitating centralized cleaning of waste chips, thereby improving cleaning efficiency.

[0004] However, existing lathes use one CNC lathe to complete the turning work, plus a vertical machining center to complete the drilling, milling and tapping. Two machine tools, two clamping, at least two processes, which is time-consuming, labor-intensive, inefficient and costly. Therefore, it does not meet the current needs. In response, we have proposed a high-precision CNC double-tool-post vertical turning center. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision CNC double-tool vertical turning center to solve the problem mentioned in the background art that existing lathes use one CNC lathe to complete the turning work, plus a vertical machining center to complete drilling, milling and tapping, two machine tools, two clamping, at least two processes, which is time-consuming, labor-intensive, inefficient and costly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision CNC dual-tool vertical turning center, comprising: a protective frame, a base inside the protective frame, a chip removal unit at the rear end of the base, a fixing fixture at the upper end of the base, a main motor on one side of the fixing fixture, a milling assembly above the fixing fixture, a servo tool post on one side of the milling assembly, a rotary table at the rear end of the servo tool post, a Z-axis unit at the rear end of the rotary table, and a tool magazine on the other side of the milling assembly.

[0007] Preferably, the milling assembly includes a milling electric spindle, the outside of which is provided with a mounting bracket, the bottom end of which is provided with a milling cutter connecting seat, and the top end of which is provided with a connecting gear.

[0008] Preferably, a speed reducer is provided on one side of the upper end of the mounting bracket, and a drive gear is provided at the output end of the speed reducer. The output end of the speed reducer is connected to the connecting gear through the meshing of the drive gear to realize the rotation of the milling electric spindle.

[0009] Preferably, the milling assembly further includes a cylinder, a coupling is provided between the top end of the milling electric spindle and the output end of the cylinder, and a fixing frame is provided on the outside of the cylinder.

[0010] Preferably, the tool magazine includes a tool magazine cover, one end of which is provided with a tool magazine motor, and a connecting disc is provided inside the tool magazine cover.

[0011] Preferably, the tool magazine further includes a connecting seat, which is located outside the connecting disc, and multiple connecting seats are equidistantly distributed around the connecting disc.

[0012] Preferably, a turning electric spindle is provided at the top of the servo tool post.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets a milling component on one side of the servo tool holder. The output end of the reducer is connected to the connecting gear through the meshing of the drive gear to realize the rotation of the milling electric spindle, so that the milling cutter installed on the milling cutter connecting seat can rotate. The main motor drives the fixed fixture to rotate, and through the rotary table and Z-axis unit, the milling component and the servo tool holder can be fed in the X-axis and bidirectional Z-axis, and the position can be adjusted so that the milling cutter is aligned with the fixed object on the fixed fixture and the milling operation is performed. The output end of the cylinder drives the coupling to move up and down. Since the top end of the milling electric spindle and the output end of the cylinder move through the coupling, the output of the cylinder is also realized. The end drives the milling electric spindle to move upward, causing the drive gear to separate from the connecting gear, thus losing power to the milling electric spindle and stopping its rotation, achieving the effect of stopping processing. A single clamping of a part can complete the turning, milling, and drilling of the outer diameter, inner hole, and end face of disc-shaped parts, reducing the error of two clamping operations in traditional processes, improving machining accuracy, saving clamping time, and increasing machining efficiency. It solves the problem of existing lathes using one CNC lathe to complete turning operations and another vertical machining center to complete drilling, milling, and tapping operations, requiring two machine tools, two clamping operations, at least two processes, which is time-consuming, labor-intensive, inefficient, and costly.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-4 This utility model provides an embodiment of a high-precision CNC dual-tool-post vertical turning center, comprising: a protective frame 1, a base 3 disposed inside the protective frame 1, a chip removal unit 2 disposed at the rear end of the base 3, a fixing fixture 10 disposed at the upper end of the base 3, a main motor 4 disposed on one side of the fixing fixture 10, a milling assembly 8 disposed above the fixing fixture 10, a servo tool post 5 disposed on one side of the milling assembly 8, a turning electric spindle 7 disposed at the top of the servo tool post 5, and a tool magazine 9 disposed on the other side of the milling assembly 8, the tool magazine 9 including a tool magazine. The tool magazine cover 12 has a tool magazine motor 13 at one end and a connecting disc 14 inside. The tool magazine cover 12 protects the connecting disc 14 and improves safety. The tool magazine 9 also includes a connecting seat 15, which is located outside the connecting disc 14. Multiple connecting seats 15 are equidistantly distributed around the connecting disc 14. Various milling cutters are installed through the multiple connecting seats 15. The tool magazine motor 13 drives the connecting disc 14 to rotate, thereby adjusting the position of the multiple connecting seats 15 for milling cutter installation.

[0022] The milling assembly 8 includes a milling electric spindle 17, a mounting bracket 16 externally mounted on the milling electric spindle 17, a milling cutter connecting seat 18 at the bottom end of the milling electric spindle 17, a connecting gear 22 externally mounted at the top end of the milling electric spindle 17, a reducer 20 mounted on one side of the upper end of the mounting bracket 16, a drive gear 21 mounted at the output end of the reducer 20, and the output end of the reducer 20 is connected to the connecting gear 22 through the drive gear 21 to achieve rotation of the milling electric spindle 17. Figure 4 As shown, the milling assembly 8 also includes a cylinder 24. A coupling 23 is provided between the top end of the milling electric spindle 17 and the output end of the cylinder 24. A fixed frame 19 is provided outside the cylinder 24. A rotary table 6 is provided at the rear end of the servo tool holder 5. A Z-axis unit 11 is provided at the rear end of the rotary table 6. The output end of the reducer 20 is connected to the connecting gear 22 through the meshing of the drive gear 21 to realize the rotation of the milling electric spindle 17, so that the milling cutter installed on the milling cutter connecting seat 18 can move. The main motor 4 drives the fixed fixture 10 to rotate. Through the rotary table 6 and the Z-axis unit 11, the milling assembly 8 and the servo tool holder 5 can perform X-axis and bidirectional Z-axis feed, adjust the position, so that the milling cutter is aligned with the fixed object on the fixed fixture 10, and perform milling operation.

[0023] Furthermore, the output end of the cylinder 24 drives the coupling 23 to move up and down. Since the top end of the milling electric spindle 17 moves with the output end of the cylinder 24 through the coupling 23, the output end of the cylinder 24 drives the milling electric spindle 17 to move upward, causing the drive gear 21 to separate from the connecting gear 22. This results in the milling electric spindle 17 losing power and ceasing to rotate, thus stopping the machining process. A single clamping of a part can complete the turning, milling, and drilling of the outer diameter, inner hole, and end face of disc-shaped parts. Compared with traditional methods, the machining accuracy is improved by 10%; the machining efficiency is improved by 22%; labor is reduced by 50%; the floor space is reduced by 38%; and the machine tool cost is reduced by 10%.
