Description

Technical Field

[0001] This utility model relates to the field of turntable technology, and in particular to a multi-axis linkage precision turntable. Background Technology

[0002] A multi-axis linkage precision rotary table is a mechanical device that can achieve coordinated movement, positioning, and complex trajectory control of two or more rotary axes. It is usually used as the fourth, fifth, or more axes of a CNC machine tool, working in conjunction with the machine tool's X, Y, Z, and other linear axes to achieve machining of multi-faceted, multi-angled, and complex curved surfaces.

[0003] However, most existing multi-axis linkage precision turntables on the market currently use multiple bolts to fix the various axes of the turntable together, making it difficult to disassemble or install the various axes. This increases the difficulty for workers to inspect or maintain the components on the various axes of the turntable and reduces the work efficiency of the workers.

[0004] Therefore, those skilled in the art have provided a multi-axis linkage precision rotary table to solve the problems mentioned in the background art. Utility Model Content

The first bracket in the connecting mechanism is slidably connected to the first rotating block, and the first rotating block is snapped together with the plug rod. The mounting block is slidably connected to the connecting block, and the limiting rod is snapped together with the mounting block. The second bracket is slidably connected to the second rotating block, which facilitates the disassembly and assembly of various shaft parts on the turntable by the operator.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-axis linkage precision rotary table includes a base, a first bracket, and a second bracket. A connecting mechanism is provided at the upper end of the base. The connecting mechanism includes a first rotating block, a plug rod, two mounting blocks, two second rotating blocks, and two threaded rods. The upper end of the outer wall of the first rotating block is slidably connected to the first bracket. The rear end of the plug rod passes through the first bracket and is engaged with the first rotating block. A fixing bolt is threadedly connected to the middle of the upper end of the first bracket. The lower end of the fixing bolt passes through the first bracket and is threadedly connected to the plug rod. Two connecting blocks are fixedly connected to both sides of the upper end of the first bracket. The outer walls of the front and rear ends of the mounting blocks are slidably connected to the connecting blocks. Moving grooves are provided on both sides inside the first bracket. A limiting rod is threadedly connected to the upper end of the outer wall of each threaded rod. The upper ends of the limiting rods pass through the first bracket and are engaged with the mounting blocks. The outer walls of both sides of the second bracket are slidably connected to the second rotating blocks via cross keys. The above technical solution involves a first bracket slidingly connected to a first rotating block, and a plug rod passing through the first bracket and engaging with the first rotating block. The mounting block and connecting block are slidably connected, and a limiting rod is engaging with the mounting block. In conjunction with a second bracket slidingly connected to a second rotating block, this facilitates the disassembly and assembly of various shaft parts on the turntable, making it easier for workers to inspect or maintain the components on each shaft on the turntable, thus improving the work efficiency of the workers.

[0007] Furthermore, the lower end of the base is provided with multiple mounting holes, and a first servo motor is provided in the cavity inside the base. The output shaft of the first servo motor passes through the base and is fixedly connected to the first rotating block. Through the above technical solution, the entire turntable can be fixed on the CNC machine tool's machining table by using multiple mounting holes opened at the lower end of the base and multiple bolts and nuts.

[0008] Furthermore, a first bearing is fixedly connected to the lower end of the outer wall of the first rotating block, and the outer wall of the first bearing is fixedly connected to the base; By using the above technical solution, the first bearing fixedly connected to the first rotating block is fixedly connected to the base, which reduces the friction between the first rotating block and the base when the first servo motor drives the first rotating block to rotate on the base, thus improving the smoothness of rotation.

[0009] Furthermore, a second servo motor is provided in a cavity inside one of the mounting blocks, and the output shaft of the second servo motor passes through the mounting block and is fixedly connected to the second rotating block; Through the above technical solution, a second servo motor installed in a mounting block can drive a second rotating block to rotate on the mounting block, and a second bracket is slidably connected to the second rotating block through a cross groove, so that the second bracket can rotate.

[0010] Furthermore, each of the second rotating blocks has a second bearing fixedly connected to its outer wall, and the outer wall of each second bearing is fixedly connected to the mounting block. By using the above technical solution, the outer wall of the second bearing, which is fixedly connected to the second rotating block, is fixedly connected to the mounting block. This reduces the friction between the second rotating block and the mounting block when the second servo motor drives the second rotating block to rotate on the mounting block, thereby improving the smoothness and stability of the second bracket during rotation.

[0011] Furthermore, the lower ends of the outer walls of the threaded rods are rotatably connected to the first bracket, the limiting rods slide inside the moving grooves, and the lower ends of the threaded rods pass through the first bracket and are fixedly connected to knobs. The above technical solution allows workers to easily rotate the threaded rod by using a knob fixedly connected to it.

[0012] Furthermore, a third servo motor is provided in the cavity in the middle of the second bracket, and the output shaft of the third servo motor passes through the second bracket and is fixedly connected to a chuck; Through the above technical solution, the third servo motor installed inside the second bracket can drive the chuck to rotate on the second bracket, and the required type of fixture can be installed on the chuck, thereby fixing the workpiece to be processed on the turntable.

[0013] Furthermore, a third bearing is fixedly connected to the lower end of the outer wall of the chuck, and the outer wall of the third bearing is fixedly connected to the second bracket; By using the above technical solution, by fixing the outer wall of the third bearing fixedly connected to the chuck to the second bracket, friction can be reduced when the third servo motor drives the chuck to rotate on the second bracket, allowing the chuck to drive the workpiece to rotate more smoothly.

[0018] Reference Figure 1-5 This utility model provides a specific implementation method: A multi-axis linkage precision rotary table includes a base 1, a first support 3, and a second support 4. A connecting mechanism 5 is provided at the upper end of the base 1. The connecting mechanism 5 includes a first rotating block 501, a plug rod 502, two mounting blocks 505, two second rotating blocks 506, and two threaded rods 508.

The second bracket 4 is slidably connected to the second rotating block 506, so that parts of the second shaft and the third shaft are fixed. This makes it easier for workers to disassemble and assemble the various shaft parts on the turntable, and facilitates the inspection or maintenance of the components on the various shafts on the turntable, thereby improving the work efficiency of the workers.

[0020] The lower end of the base 1 has multiple mounting holes 2. A first servo motor 6 is installed in the cavity inside the base 1. The output shaft of the first servo motor 6 passes through the base 1 and is fixedly connected to the first rotating block 501. Through the multiple mounting holes 2 at the lower end of the base 1, and with the help of multiple bolts and nuts, the entire turntable can be fixed on the machining table of the CNC machine tool. The first servo motor 6 installed inside the base 1 can drive the first rotating block 501 to rotate, thereby driving the first support 3 to rotate. The lower end of the outer wall of the first rotating block 501 is fixedly connected to a first bearing 7. The outer wall of the first bearing 7 is fixedly connected to the base 1. Through the fixed connection of the first bearing 7 to the base 1, the first rotating block 501 is driven by the first servo motor 6 to rotate. When block 501 rotates on base 1, it reduces friction between the first rotating block 501 and base 1, improving the smoothness of rotation. A second servo motor 8 is installed in the cavity inside a mounting block 505. The output shaft of the second servo motor 8 passes through the mounting block 505 and is fixedly connected to the second rotating block 506.

The lower end of the outer wall of the threaded rod 508 is rotatably connected to the first bracket 3. The limiting rods 509 slide inside the moving groove 507. The lower end of the threaded rod 508 passes through the first bracket 3 and is fixedly connected to a knob 510. The knob 510 fixedly connected to the threaded rod 508 facilitates the operator to rotate the threaded rod 508. The threaded connection between the threaded rod 508 and the limiting rod 509 allows the limiting rod 509 to move up and down along the moving groove 507. By changing the snap-fit ​​state of the mounting block 505, a third servo motor 10 is installed in the cavity in the middle of the second bracket 4.

The third servo motor 10 installed inside the second bracket 4 can drive the chuck 12 to rotate on the second bracket 4. The required type of fixture can be installed on the chuck 12, thereby fixing the workpiece to be processed on the turntable. A third bearing 11 is fixedly connected to the lower end of the outer wall of the chuck 12. The outer wall of the third bearing 11 is fixedly connected to the second bracket 4. By fixing the outer wall of the third bearing 11 fixedly connected to the second bracket 4, when the third servo motor 10 drives the chuck 12 to rotate on the second bracket 4,This reduces friction, allowing the chuck 12 to rotate the workpiece more smoothly.

[0021] Working Principle: When using this multi-axis linkage precision rotary table, the operator first uses the mounting holes 2 under the base 1 and multiple bolts and nuts to fix the entire device onto the machining table of the CNC machine tool. Then, the operator connects the external power supply and control cables, and then installs a fixture on the chuck 12 to fix the workpiece to be processed on the chuck 12. Next, the operator uses the CNC machine tool control state to perform actions, driving the first rotating block 501, the second rotating block 506 and the chuck 12 to rotate through the first servo motor 6, the second servo motor 8 and the third servo motor 10, changing the rotation angle of the first support 3, the second support 4 and the chuck 12, and cooperating with the linear axis on the CNC machine tool for processing. Finally, the operator can use the knob 510 to drive the threaded rod 508 to rotate, releasing the locking state of the limiting rod 509 on the mounting block 505, removing the second support 4 from the second rotating block 506, and unscrewing the fixing bolt 503 to remove the insertion rod 502, allowing the first support 3 to separate from the first rotating block 501, facilitating maintenance and repair work.
