Description

Technical Field

[0001] The utility model relates to the technical field of gear shapers, in particular to a gear shaper for gear ring processing with rapid limiting function. Background Art

[0002] Gear ring processing requires the use of a gear shaper. When the existing gear shaper processes a gear ring with a large size, it is necessary to frequently move the fixture to change the position of the gear ring so that the gear shaper cutter is aligned with the working position on the gear ring. However, since a large-size gear ring has more working positions to be processed, a large amount of time is spent on clamping and changing the working position during the processing of the entire gear ring, which affects the processing efficiency and urgently needs improvement. Summary of the Utility Model

[0003] In order to solve the above technical deficiencies, the utility model provides a gear shaper for gear ring processing with rapid limiting function, which includes a frame, an operating table, a gear shaper cutter and a mounting fixture. The operating table and the gear shaper cutter are both arranged on the frame, the mounting fixture is arranged on the operating table, the mounting fixture includes a pair of lead screw slide rails, a fixture disk, a moving table, a servo motor and a positioning mechanism. The pair of lead screw slide rails are both arranged on the operating table, the moving table is arranged on the slides of the pair of lead screw slide rails, an installation groove is formed on the moving table, the servo motor is arranged in the installation groove, the fixture disk is connected with the servo motor, the positioning mechanism is arranged on the fixture disk, the positioning mechanism includes a mounting sleeve rod, a tension spring, a positioning scale rod and a limit screw. A rod groove matching with the mounting sleeve rod is formed on the fixture disk, the mounting sleeve rod is arranged in the rod groove and connected with the rod groove through the tension spring. An installation hole matching with the positioning scale rod is formed on the mounting sleeve rod, a threaded hole communicating with the installation hole and matching with the limit screw is formed on the circumferential surface of the mounting sleeve rod, the positioning scale rod is arranged in the installation hole, and the limit screw is arranged in the threaded hole.

[0004] With the above technical solution, by setting up an installation fixture including a pair of lead screw slide rails, a fixture plate, a moving table, a servo motor, and a positioning mechanism, after placing the to-be-machined gear ring on the fixture plate and completing the limit, pull out the mounting sleeve rod of the positioning mechanism and make the positioning ruler rod located on the end face of the gear ring. Adjust the length of the positioning ruler rod extending out according to the dimensional requirements, and then tighten the limit screw to fix the positioning ruler rod. Then start the lead screw slide rail to drive the moving table to move to the position where the positioning ruler rod contacts the gear shaper cutter. After that, the lead screw slide rail stops and the position of the moving table is fixed. Then the gear shaper can be started for machining. When the gear shaping work of one station is completed, the gear shaper pauses, the servo motor starts, and drives the fixture plate to rotate according to the set program, thereby driving the gear ring to rotate to the next to-be-machined station. The gear shaper restarts for gear shaping work. Repeat the above steps until the gear shaping work of all stations is completed. In the whole process, only the cutting point of the gear shaper cutter at the first station needs to be adjusted well, and then it can work fully automatically without manual adjustment of the position of the gear ring, greatly improving the machining efficiency.
