Abstract
Description
Technical Field
[0001] This utility model relates to the field of indexing plate technology, and in particular to a high-precision direct-drive indexing plate structure. Background Technology
[0002] A high-precision direct-drive indexing table is a machine tool accessory that clamps, rotates, indexes, and positions a workpiece. Indexing tables are primarily used on milling machines, but are also commonly found on drilling machines and surface grinders. By directly connecting the drive source to the spindle, they reduce transmission links and achieve high-precision indexing and positioning.
[0003] In most existing high-precision direct-drive indexing plate structures, the indexing plate position is fixed and the angle of the indexing plate cannot be adjusted as needed to meet the special processing requirements of precision parts. Furthermore, the indexing plate cannot be locked during use, which can easily cause errors in the workpiece due to vibration or positional displacement during processing, thereby reducing processing accuracy and stability.
[0004] Therefore, those skilled in the art have provided a high-precision direct-drive indexing plate structure to solve the problems mentioned in the background art. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a high-precision direct-drive indexing plate structure. This structure allows for angle adjustment of the indexing plate as needed to meet the special processing requirements of precision parts, reduces manual intervention, and can also lock the indexing plate to ensure processing accuracy and stability, preventing errors caused by vibration or positional shift of the workpiece during processing.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A high-precision direct-drive indexing plate structure includes a base, with rotating shafts rotatably arranged on both sides inside the base. A driven gear is fixedly connected to one side of each rotating shaft and located inside the base. A first motor is fixedly arranged on one side inside the base, and a driving gear is fixedly connected to the output end of the first motor. A mounting base is fixedly connected between the two rotating shafts.
[0008] A second motor is fixedly installed in the middle of the mounting base. A connecting shaft is fixedly connected to the output end of the second motor. A gear is fixedly installed in the middle of the outer wall of the connecting shaft. A fixed cylinder is fixedly installed on one side of the mounting base. Limiting grooves are opened on both sides of the fixed cylinder. Movable blocks are slidably installed in the two limiting grooves. A connecting block is fixedly connected between the two movable blocks and located inside the fixed cylinder. A clamping plate is fixedly connected to one side of the connecting block and is engaged with the inside of the gear teeth.
[0009] Furthermore, the driving gear and the driven gear are meshed together;
[0010] The above technical solution involves the first motor rotating to drive the drive gear, which in turn drives the driven gear to rotate, thereby causing the mounting base to rotate and prompting the indexing plate to adjust its angle.
[0011] Furthermore, an indexing plate is fixedly connected to the upper end of the connecting shaft and is located inside the mounting base;
[0012] The above technical solution allows for easy installation of the workpiece to be processed by setting up an indexing plate.
[0013] Furthermore, the movable block has a threaded hole inside;
[0014] By using the above technical solution, a threaded hole is opened, and with the cooperation of the screw, the movable block is moved, so that the clamping plate is engaged in the clamping teeth of the gear.
[0015] Furthermore, a screw is rotatably provided inside the front end of the mounting base, and one end of the screw that extends into the fixed cylinder is rotatably provided in a threaded hole;
[0016] The above technical solution involves rotating the screw and moving the connecting block through the engagement of the threaded hole, which in turn causes the clamping plate to move and engage with the teeth of the gear, thereby locking the indexing plate.
[0017] Furthermore, a handle is fixedly connected to the front end of the screw;
[0018] The above technical solution allows the handle to drive the screw to rotate, causing the screw to rotate inside the threaded hole, thereby moving the clamping plate.
[0019] Furthermore, fixing blocks are fixedly provided on both sides of the base;
[0020] The above technical solution allows for the installation of fixing blocks to facilitate the fixation of the structure.
[0021] This utility model has the following beneficial effects:
[0022] 1. This utility model proposes a high-precision direct-drive indexing plate structure. By setting up a first motor, a driving gear, a driven gear, and a rotating shaft, the angle of the indexing plate can be adjusted as needed to meet the special processing requirements of precision parts. This reduces manual intervention, improves production efficiency, and lowers operational risks. By setting up a fixed cylinder, a movable block, a connecting block, threaded holes, and a screw, a clamping plate can be engaged with the teeth of the gears, thereby locking the indexing plate and ensuring processing accuracy and stability, preventing errors caused by vibration or positional displacement of the workpiece during processing.

Fixing blocks 19 are fixedly installed on both sides of the base 1 to facilitate the fixation of the structure.
[0033] Working principle: When this high-precision direct-drive indexing plate structure is in use, the first motor 4 drives the drive gear 5 to rotate, which in turn drives the driven gear 3 to rotate, and then drives the mounting base 6 to rotate, causing the indexing plate 9 to adjust its angle to meet the special processing requirements of precision parts and reduce manual intervention. The second motor 7 drives the rotating shaft 8 to rotate, which in turn drives the indexing plate 9 to rotate. The rotating handle 18 drives the screw 17 to rotate, and with the cooperation of the threaded hole 15, it drives the connecting block 14 to move, causing the clamping plate 16 to move and engage with the clamping teeth of the gear 10, thereby locking the indexing plate 9, ensuring processing accuracy and stability, and preventing errors caused by vibration or positional displacement of the workpiece during processing.
