Abstract

The utility model relates to an extrusion hydraulic device for inverse tapering tooth-sleeve of automobile synchronizers. The utility model is characterized in that an upright post arranged on a working table is provided with a lower slide block, an upper slide block and an upper overhead beam, wherein, the upper overhead beam is penetrated with an extruding oil cylinder which is connected with the upper slide block and a clamping oil cylinder which is fixed with the lower slide block after the penetration with the upper slide block. The upper slide block is provided with a pressure lever which penetrates through the lower slide block, and a base seat which is fixedly arranged on the working table is provided with an adjusting shim and a bracing ring, and furthermore, rise knives are arranged in the ring. The outer side of the ring is provided with a transverse slide block with clamping claws, and a cone sleeve which is attached with the transverse slide block is arranged on the base seat, and furthermore, a pressing ring is arranged on the lower slide block corresponding to the cone sleeve. The utility model has the advantages of low processing cost, high precision and high efficiency.

Description

The squeezed fluid pressure device that is used for automobile synchronizer tooth cover back taper

The utility model belongs to B30B hydraulic press class technology, particularly relates to a kind of squeezed fluid pressure device that is used for automobile synchronizer tooth cover back taper.

In known technology, processing automobile synchronizer gear sleeve back taper generally adopts the Digit Control Machine Tool machining or selects the processing method of hydraulic pressure for use, and the common deficiency that their exist is, processing cost height not only, but also efficient is very low and low precision.

The purpose of this utility model be to overcome the deficiency in the known technology and provide that a kind of processing cost is low, efficient and all high squeezed fluid pressure device that is used for automobile synchronizer tooth cover back taper of precision.

The purpose of this utility model is achieved in that

On workbench of the present utility model, install four columns, by column sliding block is housed successively, top shoe, entablature, centre at entablature is coated with extrusion oil cylinder, the piston rod of its oil cylinder even is loaded on top shoe, two ends at entablature also are coated with clamping cylinder, the piston rod of these two clamping cylinders is installed in sliding block after passing top shoe, on top shoe, send out the blue depression bar that has spring that installs by top board and connection, depression bar installs lower platen after passing sliding block, the termination of depression bar is fixed with pressure head, on workbench, install base, on the position base corresponding, install adjusting pad with the depression bar seaming chuck, also be fixed with the lower support circle on the base, on the lower support circle, install bracing ring, in the bracing ring of forming by upper support circle and lower support circle, be movably installed with the cutter that rises, by the screw that has spring cross slider is housed in the bracing ring outside, install clamp jaw on the cross slider, the tapered sleeve that mounts with cross slider is installed on base by the screw that has spring, installs compacting ring on the position of the sliding block corresponding with tapered sleeve.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the partial cutaway diagrammatic sketch of Fig. 1.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Four columns 2 are packed on the workbench 1 of the present utility model by screw 6, by column sliding block 3, top shoe 4 and entablature 5 are housed successively, be coated with extrusion oil cylinder 8 in the centre of entablature, the piston rod and the top shoe that pass the extrusion oil cylinder of entablature connect dress.Two ends at entablature also are coated with clamping cylinder 7, the piston rod of these two clamping cylinders installs with sliding block after passing top shoe, sending out orchid 20 by top board 19 and connection on top shoe installs with the depression bar 21 that has spring 22, depression bar installs lower platen 17 after passing sliding block by the through hole on the sliding block 18 again, and the termination of passing the depression bar of lower platen is fixed with pressure head 23.Connect the above-mentioned base 12 that on workbench, also is fixed with, on the position base corresponding, install adjusting pad 24 with the depression bar seaming chuck, lower support circle 26 is packed on the base, upper support circle 27 installs by screw and lower support circle 26, in the bracing ring of forming by upper support circle and lower support circle, be movably installed with the cutter 25 that rises, by the screw 30 that has spring 29 cross slider 28 is housed also in the bracing ring outside, but on cross slider, be fixed with the clamp jaw 15 of clamping work pieces 16, different size according to processing work, can change clamp jaw at any time and the cutter that rises, to satisfy the demand of each side.Repeat the tapered sleeve 11 that mounts with cross slider and be installed on base, on the position of the sliding block corresponding, install compacting ring 10 with tapered sleeve by the screw 14 that has spring 13.

Advantage and the good effect that the utlity model has are: novel structure, reliable, property Can be stable. The back taper of the gear sleeve of automobile synchronizer that use the utility model processes both added Worker's cost is low, guarantees that again quality of finished product good, precision height and efficient are also high.
