Description

Technical Field

[0001] This utility model relates to the field of machine tool cradle turntable technology, and in particular to a five-axis machine tool cradle turntable structure. Background Technology

[0002] A cradle-type machining platform for CNC machine tools, also known as a rotary table or turntable, is a special machine tool cradle design primarily used to achieve the horizontal rotation of the workpiece. It is used in CNC machine tools for multi-axis machining or processes requiring the cutting of complex shapes. Cradle-type machining platforms are widely used in CNC machine tools, especially suitable for machining complex-shaped parts and multi-faceted cutting. By controlling the movement of the rotary platform, continuous machining, multi-angle machining, and symmetrical machining operations can be achieved, greatly improving machining efficiency and accuracy.

[0003] However, most existing cradle-type machining platforms use single-motor direct drive. Although single-motor direct drive eliminates the transmission chain, the output torque and rigidity of a single motor are limited. When bearing heavy workpieces or performing heavy-load cutting, it is difficult to overcome the huge overturning moment, resulting in insufficient platform rigidity and poor stability, which restricts the improvement of machining capacity and precision limits. In addition, existing cradle-type machining platforms have complex structures and high production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a five-axis machine tool cradle turntable structure, which can solve at least one of the above-mentioned technical problems. The technical solution of this utility model is as follows:

[0005] A five-axis machine tool cradle turntable structure includes: a base, a support frame on the base, servo motors symmetrically arranged on the support frame, a cradle frame connected between each of the servo motors, and a fixed platform on the cradle frame.

[0006] Furthermore, a first oblique clearance groove is provided on the rear side of the base, and a workpiece mounting position is provided on the front side of the base.

[0007] Furthermore, a second oblique clearance groove is provided on the rear side of the support frame, and mounting grooves are provided on the left and right sides of the support frame. Each of the servo motors is installed and fixed in the mounting groove, and a through groove is provided on each of the mounting grooves. The output end of each of the servo motors passes through the through groove.

[0008] Furthermore, the motor mount is fixedly installed on the base.

[0009] Furthermore, the fixing platform is disc-shaped, with multiple T-shaped grooves spaced apart on the fixing platform, and multiple recessed holes arranged around the center of the fixing platform.

[0010] Furthermore, a shaft tube is provided in the middle of the cradle frame, and the fixing platform is sleeved on the shaft tube.

[0011] Preferably, the base is provided with multiple weight-reducing grooves.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This utility model provides a five-axis machine tool cradle turntable structure. When in use, the user installs and fixes the workpiece fixture on the fixed table. When the five-axis machine tool is operating, the cradle frame can be driven by servo motors symmetrically arranged on the support frame to swing to the appropriate processing position. Compared with the prior art, it adopts single and dual motor drive, provides sufficient output torque and rigidity, and has a simple structure. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 3 The five-axis machine tool cradle turntable structure shown is characterized by comprising: a base 1, a support frame 2 on the base 1, servo motors 3 symmetrically arranged on the support frame, a cradle frame 4 connected between each of the servo motors 3, and a fixed platform 5 on the cradle frame 4.

[0020] The above-described five-axis machine tool cradle turntable structure allows the user to install and fix the workpiece fixture on the fixed table 5 during use. When the five-axis machine tool is in operation, the cradle frame 4 can be driven by servo motors 4 symmetrically arranged on the support frame 2 to swing to a suitable processing position. Compared with the existing technology, the single and dual motor drive provides sufficient output torque and rigidity, and the structure is simple.

[0021] like Figure 2 and 3As shown, a first inclined clearance groove 11 is provided on the rear side of the base 1, and a workpiece mounting position 12 is provided on the front side of the base 1. When the cradle frame 4 swings, it can swing in the first inclined clearance groove 11 to avoid airflow. The workpiece mounting position 12 can be used to install a five-axis tool changer. The overall installation is tighter and the production space is increased.

[0022] like Figure 2 As shown, in some embodiments of this utility model, a second oblique clearance groove 21 is provided on the rear side of the support frame 2, and mounting grooves 22 are provided on the left and right sides of the support frame 2. Each of the servo motors 3 is installed and fixed in the mounting groove 22. Each of the mounting grooves 22 is provided with a through groove 23, and the output end of each of the servo motors 3 passes through the through groove 23. When the cradle frame 4 swings, it can swing in the second oblique clearance groove 21 to avoid clearance. At the same time, the installation and fixing of each servo motor 3 in the mounting groove 22 enhances the stability of the operation of the cradle frame 4.

[0023] like Figure 2 As shown, in some embodiments of this utility model, a motor mount 31 is installed and fixed on each of the servo motors 3. Each of the motor mounts 31 is fixedly installed on the base 1. Each servo motor 3 can be fixedly mounted on the base 1 through the motor mount 31, thereby reducing the impact of vibration caused by the operation of the servo motor 3.

[0024] like Figure 2 As shown, in some embodiments of this utility model, the fixing platform 5 is disc-shaped, and a plurality of T-shaped grooves 51 are provided at intervals on the fixing platform 5, and a plurality of recessed holes 52 are provided around the middle of the fixing platform 5 at intervals.

[0025] A shaft tube 41 is provided in the middle of the cradle frame 4, and the fixing platform 5 is sleeved on the shaft tube 41.

[0026] T-slots 51 are spaced apart on the disc-shaped fixed platform 5, allowing the clamp to be fixed at multiple angles during installation, adapting to clamps of different specifications and shapes. At the same time, when installing the fixed platform 5, the user can rotate the fixed platform 5 on the shaft tube 41 to the required angle and fix the fixed platform 5 through the countersunk hole 52 and bolts.

[0027] like Figure 3 As shown, in some embodiments of this utility model, a plurality of weight-reducing grooves 13 are provided on the base 1. Each weight-reducing groove 13 can reduce the overall weight of the base 1, making the overall weight of the five-axis device lighter than that of the prior art.

[0028] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
