Description

Technical Field

[0001] The utility model relates to the technical field of indexing numerically controlled rotation, in particular to a gear indexing numerically controlled rotary workbench. Background Art

[0002] The gear indexing CNC rotary table is an important component of CNC milling machines and other equipment. With the development of the manufacturing industry, the requirements for machining accuracy and efficiency are getting higher and higher. CNC technology came into being, which can accurately control the motion trajectory and processing parameters of machine tools. In the field of rotary tables, people began to explore the application of CNC technology to the indexing control of the table to improve the indexing accuracy and degree of automation. CNC technology can control the rotation angle of the motor through pre-written programs, which can achieve higher precision, such as reaching an indexing accuracy of several seconds (angle unit) or even higher. This makes it possible to process high-precision gears, aerospace parts and other products with extremely high precision requirements;

[0003] The gear indexing rotary table currently used generally sends instructions to the servo driver by the CNC system to control the rotation of the servo motor. The motor drives the table to rotate through the gear transmission mechanism, achieving precise indexing according to the transmission ratio. The encoder detects the position and angle of the table and feeds back to the CNC system to ensure accuracy. After the index is in place, the clamping and positioning mechanism ensures the stability of the table during processing.

[0037] Working principle: First, when it is necessary to inspect and maintain the wearing parts, the rotating rod 20 should be rotated to drive the pull rope 19 to retract, thereby driving the card block 17 to move. When the card block 17 moves, the spring 18 will be squeezed and contracted, thereby driving the card block 17 to disengage from the card slot 16, thereby realizing the rapid disassembly of the shell 14. When installing, put the body 14 into the control console 7, loosen the rotating rod 20, and the spring 18 will reset, so that the card block 17 fits into the card slot 16, and the shell 14 can be quickly installed, thereby facilitating the installation of the shell. 14 can be inspected and maintained for wearing parts, which reduces the labor intensity of the staff and greatly reduces the influence of parts wear on the processing indexing accuracy, thereby improving product quality. When the gear is processed, the vibration generated will be partially offset by the action of the polyurethane layer 12, and then the spring 23 will be forced to compress downward, and form an upward force after compression, so that the force generated by the vibration and the force of the spring 23 offset each other, thereby greatly reducing the influence of the vibration on the worm wheel 22 and the worm 21, thereby improving the processing accuracy.
