Description
Technical Field
The utility model relates to a gear drive technical field especially relates to a gear drive pneumatic gearshift.
Background
The gear transmission is a device for transmitting motion and power by a gear pair, and is a mechanical transmission mode which is most widely applied in various modern equipment. The gear transmission has the characteristics of high transmission precision, wide application range, long service life and the like, and can realize transmission between any two spatial shafts such as parallel shafts, intersecting shafts, staggered shafts and the like.
The traditional gear shifting structure is completed by adopting a hydraulic or mechanical method, the structure is complex, the buffering performance is insufficient, and the shifting efficiency is low, so that a numerical control spinning processing rear support accessory is provided for solving the problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a gear transmission pneumatic gear shifting mechanism.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a pneumatic gearshift of gear drive, includes the headstock, be provided with the axis of rotation in the headstock, a plurality of fixed gears of outer wall fixedly connected with of axis of rotation, the headstock internal rotation is provided with the pivot, the slip cap is equipped with the glide gear on the outer wall of pivot, one side inner wall fixed mounting of headstock has the multistation cylinder, the output shaft fixedly connected with shift fork of multistation cylinder, the shift fork is connected with the transmission of glide gear.
Preferably, the outer wall of the multi-station cylinder is detachably and fixedly provided with a magnetic ring.
Preferably, the fork is made of wear resistant brass.
Preferably, a grease accommodating groove is formed at a contact position of the shifting fork and the sliding gear.
Compared with the prior art, the beneficial effects of the utility model are that:
1. in the utility model, the multi-station cylinder can drive the shifting fork to push the sliding gear to move according to the control instruction requirement, so as to realize gear shifting of the gear box;
2. the utility model discloses in, because gaseous compressibility and adjustable speed nature in the multistation cylinder, so the process of shifting is flexible, can effectively reduce the gear impact, and it is rapid to shift gears.
The utility model discloses simple structure utilizes multistation cylinder and shift fork to promote the sliding gear and removes, realizes that the gear box shifts, and the process of shifting is flexible, and it is effectual to reduce the gear impact buffering, has improved the efficiency of shifting, and the use cost is cheap, has reduced manufacturing cost, and follow-up maintenance is succinct, easily realizes the automation of shifting, and the operation is simple and direct, convenient to use.

In the figure: 1. a multi-station cylinder; 2. a shifting fork; 3. a slip gear; 4. fixing a gear; 5. And (4) a main spindle box.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Example one
Referring to fig. 1, a gear drive pneumatic gearshift, including headstock 5, 5 are provided with the axis of rotation in the headstock, a plurality of fixed gears 4 of outer wall fixedly connected with of axis of rotation, 5 internal rotations of headstock are provided with the pivot, and the slip cap is equipped with sliding gear 3 on the outer wall of pivot, and one side inner wall fixed mounting of headstock 5 has multistation cylinder 1, and the output shaft fixedly connected with shift fork 2 of multistation cylinder 1, shift fork 2 and 3 transmission connection of sliding gear.
Example two
The embodiment is improved on the basis of the first embodiment: can dismantle fixed mounting have a magnetic ring on the outer wall of multistation cylinder 1, shift fork 2 is made by wear-resisting brass, and shift fork 2 and sliding gear 3's contact department is provided with the lubricating grease holding tank.
The working principle is as follows: firstly, the multi-station cylinder 1 drives the shifting fork 2 to push the sliding gear 3 to move according to the requirements of a control program, gear shifting (working gear) of the gear box is realized, after work is finished, the multi-station cylinder 1 drives the shifting fork 2 to push the sliding gear 2 to move according to the requirements of a control instruction, gear shifting (neutral gear) of the gear box is realized, a work cycle is completed, and a gear in-place signal is sent to a machine tool control system by a magnetic ring arranged on the multi-station cylinder 1.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
