Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining center technology, specifically a rotary mechanism for machining centers. Background Technology
[0002] Machining centers use a CNC system to precisely position and move the machine tool along its coordinate axes (usually X, Y, and Z axes), while simultaneously controlling the spindle's rotational speed and cutting feed rate. The workpiece is mounted on the worktable, and the cutting tool is mounted on the spindle. Based on a pre-programmed machining program, the CNC system directs the machine tool to automatically perform cutting operations, including milling, drilling, boring, and tapping. The rotary drive generates power, which is transmitted to the rotary worktable or spindle via a transmission mechanism, causing it to rotate at a specific speed and angle.
[0003] However, existing technologies still have the following problems:
[0004] First, most existing rotary mechanisms used in machining centers cannot guarantee high rotational accuracy while maintaining a simple structure. If it is difficult to achieve precise vertical rotation of the workpiece, it cannot meet the high-precision machining requirements of machining centers for different angles. In some machining tasks with high angular accuracy requirements, the machining error may be large due to insufficient accuracy of the rotary mechanism. If the structure is complex, it is not easy to maintain, and the disassembly and installation process is cumbersome, consuming a lot of time and manpower.
[0005] Secondly, the rotary mechanisms used in existing machining centers are generally not very versatile. They may only have a single direction of rotation and cannot drive rotation in two axial directions, which limits the machining center's ability to process in different axes and is not convenient for handling workpieces of different lengths. This requires changing different clamping devices or performing complex adjustment operations, which reduces machining efficiency.
[0006] To address the aforementioned problems, the inventors proposed a rotary mechanism for machining centers. Utility Model Content
[0007] To address the issues of not being able to guarantee both simple structure and high rotational accuracy while also having limited versatility, the purpose of this invention is to provide a rotary mechanism for machining centers.
[0008] To solve the above technical problems, the present invention adopts the following technical solution: a rotary mechanism for a machining center, including a base, with supports fixedly mounted on both sides of the upper end of the base, and a machine body mounted on the supports for machining workpieces. A support plate is mounted above the base, and a rotary box is fixedly mounted on the upper end of the support plate. A first motor is fixedly mounted on one side of the upper end of the support plate, and a guard plate is fixedly mounted between the first motor and the lower end of the support plate to protect and support the first motor. The output end of the first motor passes through the rotary box and is fixedly mounted with a drive gear. A side gear is meshed with the outer surface of the drive gear, and the lower end of the side gear is rotatably connected to the lower inner wall of the rotary box. A support rod is fixedly mounted on the upper end of the side gear, and a clamping plate is fixedly mounted on the upper end of the support rod.
[0009] Preferably, a fixed plate is provided between the two brackets, and a movable plate is provided at the upper end of the base. A second motor is fixedly provided at one end of the movable plate, and the output end of the second motor passes through the movable plate and is fixedly provided with a movable clamping component. A fixed clamping component is rotatably provided at one end of the fixed plate. The movable clamping component and the fixed clamping component are located on the same axis. The movable clamping component and the fixed clamping component are common three-jaw chucks or four-jaw chucks, which are existing mature technologies, so they will not be described in detail here. A support member is provided on one side of the upper end of the base, and a telescopic air rod is fixedly provided on the inner wall of one side of the support member. The output end of the telescopic air rod is fixedly connected to the movable plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model, through a vertical rotation mechanism composed of a first motor, a drive gear, a side gear, a support rod, and a clamping plate, can achieve precise vertical rotation of the workpiece, meeting the machining center's needs for machining at different angles;
[0012] 2. This utility model uses a second motor to drive the moving clamping component to rotate, thereby realizing the lateral rotation of the workpiece and forming another axial rotation drive mechanism. The telescopic pneumatic rod extends and retracts to adjust the position of the moving plate, so that the distance between the moving clamping component and the fixed clamping component can adapt to workpieces of different lengths, ensuring effective clamping of workpieces of various lengths. The rotation structure in both directions is easy to disassemble, and users can choose to install and use different structures according to their needs, improving the flexibility and adaptability of the machining center.

Mounting plates 32 are fixedly mounted on both sides of the upper end of the base 1. The support plate 31 is connected to the two mounting plates 32 by bolts. A rotary box 3 is fixedly mounted on the upper end of the support plate 31. A first motor 33 is fixedly mounted on one side of the upper end of the support plate 31. The output end of the first motor 33 passes through the rotary box 3 and is fixedly mounted with a drive gear 34. The outer surface of the drive gear 34 is meshed with... The device includes a side gear 35, the lower end of which is rotatably connected to the lower inner wall of the rotary box 3. A support rod 36 is fixedly mounted on the upper end of the side gear 35, and a clamping plate 37 is fixedly mounted on the upper end of the support rod 36. The base 1 and the bracket 2 provide a stable support structure for the entire device, ensuring its stability during operation. The support plate 31 and the mounting plate 32 are connected by bolts, facilitating the installation and disassembly of the rotary box 3. When vertical rotation of the workpiece is required, the first motor 33 is started, and its output drives the drive gear 34 to rotate. The drive gear 34 meshes with the side gear 35, causing the side gear 35 to rotate. The side gear 35 drives the support rod 36 to rotate, which in turn causes the clamping plate 37 to rotate. The vertical rotation mechanism, consisting of the first motor 33, drive gear 34, side gear 35, support rod 36, and clamping plate 37, enables precise vertical rotation of the workpiece, meeting the machining center's requirements for machining at different angles.

Reinforcing sliding columns 39 are fixedly provided on both sides of the lower end of the clamping disc 37. An annular groove 310 is provided at the upper end of the rotating box 3 to cooperate with the reinforcing sliding column 39. The conical sleeve 38 on the outer surface of the clamping disc 37 is in movable contact with the upper end of the rotating box 3, which plays a stabilizing and protective role during rotation and prevents waste from entering and causing an impact. At the same time, the reinforcing sliding column 39 at the lower end of the clamping disc 37 slides in the annular groove 310 at the upper end of the rotating box 3 to ensure the stability of the clamping disc 37 in the vertical direction.
[0022] Example 2: Figure 2-4As shown, a fixed plate 41 is provided between the two brackets 2, and a movable plate 4 is provided at the upper end of the base 1. A second motor 46 is fixedly provided at one end of the movable plate 4.

The two clamping members work together to clamp and fix the workpiece. The telescopic air rod 49 on the support member 48 is activated to extend and retract, adjusting the position of the moving plate 4, so that the distance between the moving clamping member 47 and the fixed clamping member 45 can adapt to workpieces of different lengths, ensuring effective clamping of workpieces of various lengths. The second motor 46 is activated, and its output end drives the moving clamping member 47 to rotate, thereby realizing the lateral rotation of the workpiece, forming another axial rotation drive mechanism.

Two installation blocks 413 are fixedly provided on the upper part of the inner wall of one side of the base 1, and the lower ends of the installation strip 412 are respectively connected to the two installation blocks 413 by bolts. The rod 42 and the groove 43 ensure the stability of the fixed plate 41, making the structure of the fixed plate 41 and the moving plate 4 easy to disassemble. Users can choose to install and use different structures according to their needs, which improves the flexibility and adaptability of the machining center. The installation strip 412 and the installation block 413 ensure the stability of the support member 48, and the support plate 410 and the support groove 411 ensure the smoothness of the lateral movement of the moving plate 4.
[0024] Working Principle: The base 1 and bracket 2 provide a stable support structure for the entire device, ensuring its stability during operation. The support plate 31 and mounting plate 32 are connected by bolts, facilitating the installation and disassembly of the rotating box 3. When vertical rotation of the workpiece is required, the first motor 33 is started, and its output drives the drive gear 34 to rotate. The drive gear 34 meshes with the side gear 35, causing the side gear 35 to rotate. The side gear 35 drives the support rod 36 to rotate, which in turn causes the clamping plate 37 to rotate. The vertical rotation mechanism composed of the first motor 33, drive gear 34, side gear 35, support rod 36, and clamping plate 37 can achieve precise vertical rotation of the workpiece, meeting the machining center's needs for machining at different angles.
[0025] The conical sleeve 38 on the outer surface of the clamping disc 37 is in active contact with the upper end of the rotating box 3, which plays a stabilizing and protective role during rotation and prevents waste chips from entering and causing an impact. At the same time, the reinforcing sliding column 39 at the lower end of the clamping disc 37 slides in the annular groove 310 at the upper end of the rotating box 3, ensuring the stability of the clamping disc 37 in the vertical direction.
[0026] The telescopic air rod 49 extends and retracts, pushing the moving plate 4 to move, so that the moving clamping member 47 is close to the fixed clamping member 45. The two clamping members work together to clamp and fix the workpiece. The telescopic air rod 49 on the support member 48 is activated to extend and retract, adjusting the position of the moving plate 4, so that the distance between the moving clamping member 47 and the fixed clamping member 45 can adapt to workpieces of different lengths, ensuring effective clamping of workpieces of various lengths. The second motor 46 is activated, and its output end drives the moving clamping member 47 to rotate, thereby realizing the lateral rotation of the workpiece, forming another axial rotation drive mechanism.
[0027] The insertion rod 42 and the rod groove 43 ensure the stability of the fixed plate 41, making the fixed plate 41 and the moving plate 4 structure easy to disassemble. Users can choose to install and use different structures according to their needs, which improves the flexibility and adaptability of the machining center. The mounting strip 412 and the mounting block 413 ensure the stability of the support 48, and the support plate 410 and the support groove 411 ensure the smoothness of the lateral movement of the moving plate 4.
