Abstract
The invention discloses a tooth aligning shrinkage fitting clamp for a duplicate gear. The tooth aligning clamp adopts a vertical tooth aligning structure, a workpiece is radially positioned in a manner of fixing a mandrel; two tooth aligning blocks adopt V-shaped structures; a drive device of a lower tooth aligning block adopts a thread lead screw structure, and a drive device of an upper tooth aligning block adopts a spring push structure; and each tooth aligning block and the corresponding drive device adopt a split structure. The tooth aligning shrinkage fitting clamp for the duplicate gear has the characteristics of simple structure, convenience in operation and high accuracy.
Description
Technical field
The present invention relates to field of machining, especially a kind of duplicate gear is to tooth hot charging anchor clamps.
Background technology
Certain model transmission reverse gear idler gear adopts duplicate gear electron beam welding assembly structure, and requires in two gear rings certain two tooth transverse tooth thickness direction symmetry in 0.15 mm.This duplicate gear is Split type structure before assembling, and the assembly mating part is interference fit, if adopt general press-loading process, is press-fitted may make in the process and tooth clamper is produced distortion, the precision forfeiture.
Summary of the invention
The purpose of solution of the present invention is to propose a kind of duplicate gear to tooth hot charging anchor clamps, and it has simple in structure, and is easy to operate, the characteristics that the degree of accuracy is high.
The technical scheme that the present invention solves its technical problem employing is: this adopts up and down to toothing tooth clamper, with the stationary spindle mode workpiece is carried out radial location, two pairs of tooth pieces adopt V-structure, wherein lower drive unit to the tooth piece is the threaded screw rod structure, upper drive unit to the tooth piece is spring pushing structure, and each adopts Split type structure to the tooth piece drive unit corresponding with it.
Described anchor clamps, sliding plate is connected on the base by chute, guiding axle and axle are fixed by screws on the base, hold-down nut links to each other with sliding plate by screw, star grip knob links to each other with screw rod by straight pin, screw rod is by attachment screw and connecting pin and slide block, slide block connects tooth bar, gland is connected by screw slide block b, slide block a links to each other by terminal pad with slide block b, and the hand button is by the straight pin cylinder lever connecting rod, and cover has cylindrically coiled spring on the pull bar, the end of the other end connection sliding block b of pull bar, the other end of slide block b is connected with tooth bar.
Beneficial effect of the present invention is: the tooth piece is adopted V-structure, can realize transverse tooth thickness to transverse tooth thickness to the tooth requirement, the error of having avoided the benchmark conversion to bring; Lower drive unit adopts the threaded screw rod structure, can realize accurately radial position location, to satisfy the positioning requirements of master gear spare; Upper drive unit adopts spring pushing structure, can reduce V-block and screw in the time, and realize automatically the tooth function has been reduced the impact of human factor; Tooth piece and its drive unit are adopted Split type structure, can be used in conjunction with calibrating device according to two gear ring tooth section symmetry detection case of total member, check at any time and clamping fixture for correcting, and reduced the anchor clamps manufacture difficulty.

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing: as shown in Figure 1, this adopts up and down to toothing tooth clamper, with the stationary spindle mode workpiece is carried out radial location, two pairs of tooth pieces adopt V-structure, wherein lower drive unit to the tooth piece is the threaded screw rod structure, upper drive unit to the tooth piece is spring pushing structure, and each adopts Split type structure to the tooth piece drive unit corresponding with it.The sliding plate of these anchor clamps is connected on the base by chute, guiding axle and axle are fixed by screws on the base, hold-down nut links to each other with sliding plate by screw, star grip knob links to each other with screw rod by straight pin, screw rod is by attachment screw and connecting pin and slide block, slide block connects tooth bar, gland is connected by screw slide block b, slide block a links to each other by terminal pad with slide block b, the hand button is by the straight pin cylinder lever connecting rod, cover has cylindrically coiled spring on the pull bar, the end of the other end connection sliding block b of pull bar, and the other end of slide block b is connected with tooth bar.
In duplicate gear when assembling, is for avoiding using the press-loading process mode, adopted hot-mounting process, being about to dish gear with holes is heated to about 150 ℃, its endoporus is heated produces and expand, then its mode with matched in clearance is packed on the gear shaft, after total member cooling, can satisfy the interference fit requirement of assembling.After the assembling, duplicate gear is sleeved on the axle of these anchor clamps, up and down to the tooth piece, duplicate gear is carried out the symmetry fine setting by V-shaped structure, it is met the demands.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, with reference to embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.Without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and all in the claimed scope of the invention, the claimed scope of the present invention is defined by appending claims and equivalent thereof these changes and improvements.
