Detailed Description

The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.

As shown in fig. 1 to 4, the gear machining tool of the present embodiment includes a mounting base 1 and a plurality of jaws 2, and the jaws 2 are pivotally connected to the mounting base 1. Mount pad 1 has and holds chamber 11 and ring channel 12, holds and is equipped with driving piece 3 in the chamber 11, and the cover is equipped with spring 7 on the driving piece 3. The annular groove 12 is located at the end of the mounting seat 1, the mounting seat 12 is connected with the sliding seat 4 through the annular groove 12, and a fluid cavity 5 is formed between the annular groove 12 and the sliding seat 4. The sliding seat end portion has a connecting portion 6, the connecting portion 6 is provided with a fluid passage 61, and the fluid passage 61 communicates with the fluid chamber 5 through the communication hole 41 of the sliding seat 4. The driving piece 3 penetrates through the sliding seat 4 and is fixedly connected with the connecting portion 6, the mounting seat 1 is provided with a first groove body 13, the driving piece 3 is provided with a second groove body 31, and the clamping jaw 2 is correspondingly arranged with the first groove body 13 and the second groove body 31. Among the above-mentioned technical scheme, mount pad 1 is fixed on processing or conveyer tool, when needs clamping gear, through fluid passage 61 input gas entering fluid chamber 5, the 5 internal pressure increases of fluid chamber promote the motion of sliding seat 4, and sliding seat 4 drives connecting portion 6 and driving piece 3 and removes, and spring 7 compresses, and jack catch 2 deviates from first, the second cell body, rotates clamping gear to the middle part. When the gear needs to be released, the gas delivery is stopped, and the elastic force of the spring 7 enables the driving piece 3 to reset, so that the claw 2 is driven to open and reset. Through above-mentioned technical scheme, can make jack catch automatic re-setting, need not to use motor control, reduce control cost.
