Description

The broaching tool hookup of logical main shaft in the cutting fluid

The utility model relates to a broaching tool device, particularly relates to the broaching tool hookup of logical main shaft in a kind of cutting fluid.

The broaching tool device is the main member in the processing machine, and the broaching tool device had manufacturing cost height, swivel joint spoilage height in the past, the swivel joint that changes the outfit is bothersome and desire is adjusted the inconvenient disappearance of cylinder pressure stroke.As Fig. 1, shown in 2, it is the tool-broaching mechanism of logical main shaft in the cutting fluid of No. the 86208026th, the novel patent application in Taiwan, its main shaft 10 outsides are consolidated with a gear 12 that driven by motor 11, and inside is provided with a perforation 101 and can wears for axle 13, this main shaft 10 pushes up outside the section and is equipped with a cylinder pressure 14, the fixed part 141 of this cylinder pressure 14 is to be fixedly arranged in facility (figure does not show), being provided with a perforation 143 in the drive division 142 of this cylinder pressure 14 can be for swivel joint 15 device, one fixed base frame 20 is base bodies 22 of establishing big external diameter in a fore-set body 21 bottoms, the endoporus 23 top section screws 231 of this fixed base frame 20 are to put for bolted joint 151 spiral shells of this swivel joint 15, this base body 22 is provided with most jacks 221, and can tie in main shaft 10 by bolt 24 locks, and driven by this main shaft 10 and rotate, one driving pedestal 30 is hollow base frames of the suitable external diameter of a tool, the jack 221 that corresponds to this fixed base frame 20 on it is provided with most breach 31, being formed with most inserting parts 32 simultaneously can plant into jack 221, and and driven by this fixed base frame 20 and rotate synchronously, in addition, but 33 end of the endoporus section screw 331 of this driving pedestal 30 is spiral shell knot axles 13, one disc 34 is to be nested with outside fore-set body 21, and can by

Bolt 35 and driving pedestal 30 lock knots, and this axle 13 is equipped with one near place, bottoms spiral shell and adjusts nut 16 and can compensate the abrasion gap, and be plugged with a hilt 17 in the bottom, this hilt 17 is the bottom faces that are fixed in main shaft 10 by taper hole, form by above-mentioned member, can solve the shortcoming of broaching tool device in the past, but, in use, discovery plugs for the inserting part 32 of this driving pedestal 30 because of the base body 22 of this fixed base frame 20 must be provided with jack 221, and must tie can be driven by it rotation by this bolt 24 and main shaft 10 locks, and this bolted joint 151 is factors such as common-use size, so the external diameter of this base body 22 can not just can be kept predetermined strength too for a short time, so, (the main shaft diameter of axle varies in size because of displacement volume is different) just has the shortcoming that can't adapt to than small axle diameter main shaft 10 when running into the less main shaft 10 of the diameter of axle.

The purpose of this utility model is to provide a kind of can adapt to various different diameter of axle main shafts, and can make the broaching tool hookup of designs simplification with logical main shaft in the cutting fluid that reduces production costs.

The utility model provides the broaching tool hookup of logical main shaft in a kind of cutting fluid, be in a main shaft, to place an axle, this axle top is equiped with a cylinder pressure, the central hole device of this cylinder pressure has a swivel joint, the bolted joint spiral shell of this swivel joint is tied in a fixed base frame, this fixed base frame also is combined with a driving pedestal, it is characterized in that:

This fixed base frame comprises a fore-set body and establishes the foundation body of big external diameter in this fore-set body bottom side, this fore-set body and bolted joint spiral shell knot, this fixed base frame is provided with an endoporus that supplies this axle to wear, and this foundation body is provided with most breach and is formed with most pins, and each pin all has been longitudinally set with a perforation;

This driving pedestal comprises an apical ring body, contract in this apical ring body bottom side and to establish an external diameter middle sleeve column identical and the sleeve column bottom side is provided with big external diameter in this end inserting column with the trepanning aperture of this foundation body, and this driving pedestal provides an endoporus that supplies this axle to place, the pin place that corresponds to this fixed base frame on this apical ring body provides most jacks for the noose pin, should middle sleeve column be the endoporus bottom of planting this fixed base frame, this end sleeve column is then planted in the endoporus top of a main shaft, and placed the pin perforation of fixed base frame by majority lock knot element, and locked the lockhole of inserting this main shaft top end face.

The broaching tool hookup of logical main shaft is characterized in that: be equipped with block in this pin in the described cutting fluid.

The broaching tool hookup of logical main shaft in the utility model cutting fluid, it is characterized in that: comprise a fixed base frame and and drive pedestal, this fixed base frame is that the foundation body of establishing big external diameter by a fore-set body and in this fore-set body bottom side is constituted, this foundation body is provided with the breach of predetermined length and is formed with the predetermined number pin, each pin all has been longitudinally set with a perforation, the endoporus of this fixed base frame can be put and place for axle for the bolted joint spiral shell, this driving pedestal is that the end sleeve column of establishing big external diameter by an apical ring body and in this apical ring body bottom side is constituted, the endoporus of this driving pedestal can place for axle, this end sleeve column is then planted in the top of main shaft, this apical ring body is to correspond to the pin of this fixed base frame and provided most jacks, pin noose by this jack and fixed base frame, and will lock knot element lock and place the perforation of this pin and the lockhole of main shaft top end face, and can be subjected to this main shaft drives and drive this driving pedestal, axle and bolted joint rotate synchronously.

By above-mentioned contexture, will make the utlity model has to adapt to various diameter of axle main shafts, and can reduce member, the effect that can relatively reduce production costs.

In sum, the advantage of the broaching tool hookup of logical main shaft is as described later in the cutting fluid of the present utility model:

1. because the utility model is by on this fixed base frame 40 pin 44 being set, tie in the jack 511 of this driving pedestal 50 to insert, make this fixed base frame 40 and drive pedestal 50 mutual nooses, and lock by the perforation 441 that this lock knot element 45 placed this pin 44 and to tie in main shaft 80, just can rotate via the driving of forming member, and can adapt to various diameter of axle main shafts 80, can solve in the past and must on the base body 22 of this fixed base frame 20, jack 221 be set so have, inserting part 33 for this driving pedestal 30 places, institute causes these base body 22 external diameters can not be too little of to keep predetermined strength, and can't adapt to shortcoming than small axle diameter main shaft 10, that is to say to the utlity model has the effect and the advantage that can adapt to various different diameter of axle main shafts 80.

2. because the utility model need not be provided with disc 34, can reduce whole formation, and can lack once group knot action, and have the effect and the advantage that can reduce production costs so have.

Below by most preferred embodiment and accompanying drawing the broaching tool hookup that leads to main shaft in the utility model cutting fluid is elaborated, in the accompanying drawing:
