Abstract

The utility model relates to a semi-automatic feeding device for a turning lathe. The semi-automatic feeding device for the turning lathe is characterized in that the semi-automatic feeding device for the turning lathe comprises a tool tailstock body and a driving air cylinder, the tool tailstock body is provided with a through hole extending in the horizontal direction, and a tailstock sleeve is matched in the through hole in a sliding fit mode; a drill bit is mounted at the front end of the tailstock sleeve, and the tail end of the tailstock sleeve is connected to the driving air cylinder; the cylinder block of the driving air cylinder is mounted to the tail end of the tool tailstock body through a connecting flange, the front end of a piston rod of the driving air cylinder is connected to the tail end of the tailstock sleeve, the rear end of the piston rod is of a thread structure, and the thread structure is in threaded connection with a regulation limit sleeve and a locking nut from front to back in sequence; the driving air cylinder is provided with a hand-operated direction valve and a one-way throttle valve. When drilling is carried out, an air intake chamber is selected by using the hand-operated direction valve, a tailstock sleeve is driven to be ejected out or drawn back in the horizontal direction through the driving air cylinder, and operation can be achieved without turning a handwheel manually. The labor intensity of workers is relieved, machining quality and the production rate are improved, and drilling time of single piece is shortened by about 40% on average.

Description

The semi-automatic feed arrangement of a kind of lathe

Technical field

The utility model relates to a kind of lathe feeding device, particularly the semi-automatic feed arrangement of a kind of lathe simple in structure, that labour intensity is low.

Background technology

When for medium caliber valve body borings such as DN50-DN65, conventionally on general horizontal lathe, process.Former processing method is to advance drill bit to cut endoporus by operative employee's hand-operated tailstock handwheel, and in the time that valve body blank adopts contour forging technique to manufacture, its texture material is harder, simultaneously, bore diameter is large and hole is darker, therefore the cutting resistance in the time of boring is very large, and operating personnel need to pay very large labour intensity and just can carry out, and therefore operating efficiency is very low.

Utility model content

The technical problems to be solved in the utility model is to provide the semi-automatic feed arrangement of a kind of lathe simple in structure, that labour intensity is low.

For solving the problems of the technologies described above, the technical solution of the utility model is: the semi-automatic feed arrangement of a kind of lathe, is characterized in that: comprise tailstock tool body, barrel of tail stock, adapter sleeve, adpting flange, driving cylinder, regulate stop collar, locking nut;

One tailstock tool body, tailstock tool body has the through hole that an along continuous straight runs extends, and is sliding combined with barrel of tail stock in through hole; The front end of barrel of tail stock is installed drill bit, and end connects driving cylinder;

One drives cylinder, and the cylinder body of this driving cylinder is arranged on the end of tailstock tool body by adpting flange; The piston rod that drives cylinder is two rod structures, and the front end of piston rod is connected with the end of barrel of tail stock by adapter sleeve, and the rear end of piston rod is helicitic texture, is threaded successively from front to back and regulates stop collar and locking nut on this helicitic texture;

In the gas circuit of driving cylinder, be equipped with hand-operated direction valve and one-way throttle valve.

The utility model has the advantage of: when boring, utilize hand-operated direction valve to select inlet chamber, and then by driving air cylinder driven tailstock sleeve pipe along continuous straight runs eject or retract, realize without the artificial handwheel that rotates.And drive cylinder responsiveness to be generally 50-500mm/S, than the quick action of hydraulic pressure and electronic mode, can make the electrodeless adjusting of cylinder speed by one-way throttle valve, reliability is high, long service life, barrel of tail stock can F.F.-rewind down, convenient chip removal midway, it is also unloaded that barrel of tail stock drives cylinder in the time of F.F., rewind down, only needs very little pressure, and profit in this way, can realize lathe power feed deep hole processing, both alleviated workman's labour intensity, and improved again crudy and productivity ratio, single-piece drilling time average shortens 40% left and right.

In addition, very little for the change of horizontal machine tool tailstock, do not destroy the original any parts of tailstock.If want lathe to recover original turning function, only need pull down adpting flange, original leading screw and adjusting nut are installed and are got back to origin-location, change convenient and swift, reduction enterprise manufacturing cost.

Accompanying drawing explanation

Fig. 1 is the semi-automatic feed arrangement structural representation of the utility model lathe.

The specific embodiment

Embodiment

Refer to Fig. 1, the utility model has disclosed the semi-automatic feed arrangement of a kind of lathe, comprises tailstock tool body 1, barrel of tail stock 2, adapter sleeve 3, adpting flange 4, drives cylinder 5, one-way throttle valve 6, hand-operated direction valve 7, piston rod 8, adjusting stop collar 9, locking nut 10.

One tailstock tool body 1, tailstock tool body 1 adopts horizontal machine tool original structure, and it has the through hole that an along continuous straight runs extends, and is sliding combined with barrel of tail stock 2 in through hole.The front end of barrel of tail stock 2 is installed drill bit, and end connects driving cylinder 5.

One drives cylinder 5, and the cylinder body of this driving cylinder 5 is arranged on the end of tailstock tool body 1 by adpting flange 6; The piston rod 8 that drives cylinder 5 is two rod structures, and the front end of piston rod 8 is connected with the end of barrel of tail stock 2 by adapter sleeve 3, and the rear end of piston rod 8 is helicitic texture, is threaded successively from front to back and regulates stop collar 9 and locking nut 10 on this helicitic texture.In addition, hand-operated direction valve 7 and one-way throttle valve 6 be equipped with in the gas circuit of driving cylinder 5.

Operation principle:

Drive cylinder 5 to control compressed air by hand-operated direction valve 7 and enter and drive in the forward and backward cavity of cylinder 5, realize bidirectional-movement, so drive barrel of tail stock 2 to drive drill bit reach or retreat hole, the technological action such as chip removal; Control the translational speed of drill bit by one-way throttle valve, realize F.F.-work and enter (creep feed midway)-actions such as rewind down; And the end of piston rod 8 arranges adjusting stop collar 9 and locking nut 10, utilize and regulate stop collar 9 to limit the displacement of drill bit, and then the degree of depth of keyhole.

Claims
