Description

Gear machining clamp

Technical Field

The utility model belongs to the technical field of gear machining equipment technique and specifically relates to a gear machining anchor clamps.

Background

The gear transmission is a device for transmitting motion and power by a gear pair, is a mechanical transmission mode which is most widely applied in various modern equipment, and has the advantages of accurate transmission, high efficiency, compact structure, reliable work and long service life. The existing gear needs to grind an inner hole after heat treatment, and before grinding, the gear to be machined needs to be positioned, for example, the patent with the publication number of CN202344391U, the publication number of 2012 is 7/25/2012, and the name of the patent is 'a clamp for gear machining', the clamp realizes the fixation of a plurality of gears through a retainer and three groups of positioning components inside the retainer, but the gears are overlapped and fixed, so that the grinding difficulty of the inner hole of the gear is increased, the clamp cannot be matched with a grinding shaft for use, and the increasing use requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a gear machining clamp, which solves the problem through a rotatable retainer with a positioning device.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a gear machining anchor clamps, includes the support column, sets up the sweeps catch tray in the support column bottom and sets up the gear holder in the support column upper end, and the gear holder comprises at least three clamping dish, and the sweeps catch tray is the same with clamping dish size, and the medial surface of clamping dish is crisscross to be provided with the supporting shoe that is used for supporting the gear and the tight axle in top that is used for pushing up tight gear.

Furthermore, the sweeps catch tray and the gear retainer are connected with the support column through a sleeve ring with a locking bolt and a connecting rod arranged outside the sleeve ring.

Furthermore, the clamping disc is a frame-shaped frame, and a supporting block and a jacking shaft on the inner side surface of the clamping disc are fixedly connected with the clamping disc in a welding mode.

Further, the supporting shoe sets up in the below of the horizontal plane of tight axle place of top.

Furthermore, one side of the scrap collecting disc is provided with an elastic sheet for limiting the clamping disc.

The utility model has the advantages that the rotatable gear retainer is used for placing a plurality of gears, the supporting blocks and the jacking shafts are arranged in the clamping disc in a staggered manner, so that the gears can be stably placed, and the gears can be firmly locked, thereby facilitating the grinding of inner holes; the sweeps catch tray of taking the shell fragment is fixed to be set up under the grinding axle, and the in-process of manual rotatory holder, clamping dish pause under the fender of shell fragment rotates for the sweeps that produces in the clamping dish internal gear grinding process is collected, and the back is accomplished in the grinding, can rotate away the clamping dish internal gear that the grinding was accomplished for the holder application of force, and convenient and fast has effectively improved the machining efficiency of gear.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a view illustrating the chuck of the present invention.

In the figure, 1, a support column, 2, a scrap collecting disc, 3, a clamping disc, 4, a support block, 5, a jacking shaft, 6, a lantern ring, 7, a connecting rod and 8, elastic sheets are arranged.

Detailed Description

As fig. 1 is the utility model discloses a structural schematic diagram, a gear machining anchor clamps, including support column 1, the sweeps catch tray 2 that sets up in support column 1 bottom and the gear holder of setting in support column 1 upper end, the gear holder comprises at least three clamping dish 3, sweeps catch tray 2 is the same with clamping dish 3 size, sweeps catch tray 2 and gear holder all are connected with support column 1 through the lantern ring 6 of taking locking bolt and the connecting rod 7 that sets up in lantern ring 6 outside, clamping dish 3 is the frame shape frame, supporting shoe 4 and the jacking axle 5 of clamping dish 3 medial surface pass through welding mode and clamping dish 3 fixed connection, supporting shoe 4 sets up in the below of jacking axle 5 place horizontal plane, one side of sweeps catch tray 2 is provided with and is used for the spacing shell fragment 8 of clamping dish 3. When in use, the supporting column 1 is fixedly arranged on a base of an inner hole grinding machine, so that the scrap collecting disc 2 and one of the clamping discs 3 are correspondingly arranged under a grinding shaft, the gear to be processed is fixed through the clamping disc 3, the side surface of the lower scrap collecting disc 2 is provided with a metal elastic sheet 8 through a bolt, the clamping disc 3 is buffered and limited in the rotation process of the gear retainer, the clamping disc 3 is conveniently arranged right above the scrap collecting disc 2, the scraps generated by grinding the inner hole are timely collected, after grinding is completed, force is manually applied to the gear retainer, the elastic force 8 has certain elasticity and can be recovered after deformation of the force application, the next clamping disc 3 is limited immediately so as to facilitate grinding operation of the inner hole, the gear after processing can be manually replaced in the rotation process of the gear retainer, the clamping disc 3 is a frame, the gear is manually ejected out from the bottom, so that the gear is convenient and quick.

As shown in fig. 2, the crisscross supporting shoe 4 that is used for supporting the gear that is provided with of medial surface of clamping dish 3 and the tight axle 5 in top that is used for the tight gear in top, tight axle 5 is through a segment connecting rod and 3 welded fastening of clamping dish, will wait to process the gear and place in clamping dish 3, make supporting shoe 4 place just in the teeth of a cogwheel below, make tight axle 5 support the tooth's socket just, thereby treat that the gear of processing stabilizes the clamping, the position and the quantity of supporting shoe 4 and tight axle 5 set up according to waiting to process the gear specification, different gears can set up the supporting shoe 4 and the tight axle 5 in top of different intervals difference quantity, after stabilizing the centre gripping to the gear, be convenient for grind the gear hole.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
