Technical Field

[0001] This utility model relates to the field of CNC rotary table technology, specifically a multi-directional machining CNC rotary table. Background Technology

[0002] The CNC rotary table is a major functional component of CNC machine tools. It can perform precise rotation, indexing, and positioning of workpieces on the worktable and is often referred to as the fourth axis of the CNC machine tool. Its linkage with the X, Y, Z and other coordinate axes of the machine tool can realize complex machining processes that are difficult to complete with conventional machine tools.

[0003] Chinese patent provides a CNC rotary table, publication number CN116984907B, including a base, a rotary table cover, a transmission assembly, and a drive component. The rotary table cover is rotatably mounted on the base, and the drive component drives the transmission assembly to rotate the rotary table cover around the axis of the base. The inner bottom wall of the base is provided with an annular tube, which is coaxially arranged with the base. The transmission assembly includes a meshing worm gear and a worm. The worm gear is annular and coaxially arranged with the annular tube. The worm gear includes multiple cylindrical rollers, and the rotary table cover is connected to the worm gear.

[0004] Although the device is equipped with a turntable and supporting facilities, which can effectively ensure transmission performance and improve the accuracy of turntable positioning, the turntable can only perform transmission on a plane, which has limitations for multi-axis machining.

[0005] Therefore, a multi-directional machining CNC rotary table is needed. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-directional machining CNC rotary table to solve the problem mentioned in the background art that traditional rotary tables only rotate in one direction and have great limitations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional machining CNC rotary table, including a mounting frame, an angle adjustment mechanism fixedly mounted on the side of the mounting frame, and a rotation mechanism fixedly mounted on the side of the angle adjustment mechanism; the angle adjustment mechanism includes a drive motor, the side of the drive motor is fixedly connected to the top surface of the mounting frame, a reduction assembly is fixedly mounted on the side of the mounting frame, the end face of the transmission rod of the reduction assembly is fixedly connected to the end face of the transmission rod of the drive motor, a connecting plate is fixedly mounted on the end face of the output rod of the reduction assembly, a base plate is fixedly mounted on the bottom surface of the connecting plate, the top surface of the base plate is fixedly connected to the bottom surface of the rotation mechanism, and a connecting piece is fixedly mounted on the side of the mounting frame.

[0008] Preferably, the rotating mechanism includes a mounting plate and a support frame. The bottom end face of the mounting plate is fixedly connected to the top end face of the base plate. A pin is fixedly installed on the top end face of the mounting plate. A bearing sleeve is fixedly installed on the side of the pin. A turbine is fixedly installed on the side of the bearing sleeve. A placement plate is fixedly installed on the top end face of the turbine.

[0009] Preferably, the top surface of the base plate is fixedly connected to the bottom surface of the support frame, a servo motor is fixedly installed on the top surface of the support frame, a second worm gear is fixedly installed on the end surface of the servo motor transmission rod, and a first fixing block is rotatably installed on the end surface of the second worm gear through a bearing seat.

[0010] Preferably, a second fixing block is fixedly installed on the top surface of the base plate, and the top surface of the base plate is fixedly connected to the bottom surface of the first fixing block. A rotating rod is rotatably installed on the side of the second fixing block through a bearing seat. A gear is fixedly installed on the side of the rotating rod, and the gear tooth surface meshes with the tooth surface of the first worm gear. A first helical gear is fixedly installed on the side of the transmission rod.

[0011] Preferably, a mounting ring is fixedly installed on the top surface of the base plate, and a through hole is fixedly opened on the side of the mounting ring. A first worm gear is rotatably installed on the inner wall of the through hole through a bearing. The tooth surface of the first worm gear meshes with the tooth surface of the turbine.

[0013] Preferably, a fixing plate is fixedly installed on the top surface of the placement plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) When using this multi-directional machining CNC rotary table, the workpiece to be processed is first fixed on the fixed plate. When the rotary table needs to rotate, the servo motor is first turned on to drive the second worm gear to rotate, which in turn drives the gear to rotate. The gear then drives the transmission rod and the first helical gear fixed on the side of the transmission rod to rotate. Then, the second helical gear meshing with the first helical gear rotates, which in turn drives the first worm gear to rotate. At this time, the first worm gear can drive the worm gear meshing with it to rotate, which drives the placement plate and the fixed plate to rotate, thus realizing the rotation of the rotary table. This improves the practicality of the device and works with the angle adjustment mechanism to realize the bidirectional rotation of the rotary table, thus improving the application scenarios and practicality.

[0016] 2) When the multi-directional machining CNC rotary table needs to revolve around the rotary table while rotating on its own axis, the drive motor is first turned on. The drive motor reduces the speed and increases the torque through the reduction assembly, and then outputs power, which drives the connecting plate and the base plate to deflect around the output rod of the reduction assembly. This causes the rotary table mounted on the top surface of the base plate to deflect. The rotation of the rotary table can improve the application scenarios of the device and improve the processing efficiency and quality of the workpiece. Attached Figure Description
