Abstract

The invention discloses a device for machining a cambered surface of a screwdriver head. The device comprises a bottom plate, a swing arm, a tool, a tool rest and a drive device, wherein the swing arm is connected to the bottom plate in a pivot mode, the tool rest is fixedly arranged at the end, facing toward a positioning device of the screwdriver head, of the swing arm, the tool is detachably fixed to the tool rest, and the drive device drives the swing arm to rotate by a set angle in a frontward and backward reciprocating mode. The tool is driven to swing in a frontward and backward reciprocating mode through the swing arm so that the cambered surface on the side wall of the circumference of the screwdriver head can be machined, the device can be suitable for various machining devices which are easy to operate, for example, the device can be applied to lathes, grinding machines, milling machines and the like, the device is easy to operate, a worker can operate the device to conduct machining only through simple training, and the device is high in workpiece machining speed, stable in quality and low in machining cost.

Description

Screwdriver head curved face processing equipment

Technical field

The present invention relates to a kind of screwdriver head processing unit (plant), refer to especially a kind of screwdriver head curved face processing equipment.

Background technology

Screwdriver head is adding man-hour, need to, at its circumferential surface processing one circle arcuation groove structure, make screwdriver head can play in use the effect that absorbs and slow down impulsive force, this arc surface is all processed by digital control processing lathe at present, processing cost is high, and common laborer is difficult to operation, and working (machining) efficiency is low.

Summary of the invention

In order to overcome above-mentioned defect, the invention provides a kind of screwdriver head curved face processing equipment, this screwdriver head curved face processing equipment is easy to use, simple to operate, can be applicable to common machine machining tool, and process velocity is fast, and processing cost is low.

The technical scheme that the present invention adopts in order to solve its technical problem: a kind of screwdriver head curved face processing equipment, comprise base plate, Swing Arm, cutter, knife rest and drive unit, Swing Arm is articulated on base plate, Swing Arm is installed with knife rest towards one end of screwdriver head positioner, cutter can be dismantled and be fixed on knife rest, and drive unit drives the positive and negative reciprocating rotation set angle of Swing Arm.

As a further improvement on the present invention, described drive unit is oil cylinder, and the cylinder body of oil cylinder is fixed on base plate, and piston rod and the Swing Arm of oil cylinder are hinged, and the described cylinder piston rod direction of motion and Swing Arm are axially not parallel.

As a further improvement on the present invention, described drive unit is servomotor, and clutch end and the Swing Arm of servomotor are coaxially connected.

As a further improvement on the present invention, be also provided with first and second positioner on described base plate, this first and second positioner respectively stop is positioned on base plate, described first and second positioner backstop both sides in Swing Arm along its rotation direction.

As a further improvement on the present invention, described first and second positioner comprises the nut being fixed on base plate and is bolted in the bolt in nut, the both sides of described bolt end stop in Swing Arm along its rotation direction.

The invention has the beneficial effects as follows: the present invention has realized the processing of cambered surface on screwdriver head circumferential side wall by the positive and negative reciprocally swinging of Swing Arm band cutter, it can be applicable to various machining apparatus simple to operate, as lathe, grinding machine, milling machine etc. all can be applied, it is simple to operate, workman only needs simple training can go up hand operated processing, and workpiece process velocity is fast, steady quality, processing cost are low.

Fig. 2 is the first use view of the present invention;

Fig. 3 is the second use view of the present invention.

The specific embodiment

Embodiment: a kind of screwdriver head curved face processing equipment, comprise base plate 1, Swing Arm 2, cutter 3, knife rest 4 and drive unit 5, Swing Arm 2 is articulated on base plate 1, Swing Arm 2 is installed with knife rest 4 towards one end of screwdriver head positioner, cutter 3 can be dismantled and be fixed on knife rest 4, drive unit 5 drives the positive and negative reciprocating rotation set angle of Swing Arm 2, during use, screwdriver head blank to be processed is fixed on the jaw of lathe, base plate 1 is fixed on the body of lathe bed, make the point of a knife of cutter 3 aim at screwdriver head lateral wall to be processed, then drive unit 5 drives Swing Arm 2 around the positive and negative reciprocating rotation of drive-connecting shaft, knife rest 4 on drive-connecting shaft just produces positive and negative swing, fix a cutting tool 3 point of a knife stroke route of knife rest 4 is just a camber line, while screwdriver head to be processed is High Rotation Speed under machine tool chuck drives, this cambered surface groove that just processes an indent on screwdriver head sidewall to be processed comes, certainly screwdriver head blank to be processed also can be fixed on miscellaneous equipment, as long as can drive its rotation, as grinding machine, on the chuck of milling machine, this device structure is simple, easy to use, applicability is strong, can realize the rapid processing of screwdriver head cambered surface.

Described drive unit 5 is oil cylinder, and the cylinder body of oil cylinder is fixed on base plate 1, and the piston rod of oil cylinder and Swing Arm 2 are hinged, and the described cylinder piston rod direction of motion and Swing Arm 2 are axially not parallel.

Described drive unit 5 is servomotor, the clutch end of servomotor and Swing Arm 2 are coaxially connected, it can certainly be the rotation of servomotor band moving cam, cam stops the positive and negative reciprocally swinging of top Swing Arm 2, or motor is realized the positive and negative reciprocally swinging of Swing Arm 2 by linkage and all can be realized, the structure that this is easy to expect according to this patent for those skilled in the art.

On described base plate 1, be also provided with first and

second positioner

6,7, this first and

second positioner

6,7 respectively stop is positioned on base plate 1, described first and

second positioner

6,7 backstop both sides in Swing Arm 2 along its rotation direction, Swing Arm 2 pendulum angles are played to restriction, prevent from that its pendulum angle is excessive to lose time or stuck.

Described first and

second positioner

6,7 comprises and is fixed on the nut on base plate 1 and is bolted in the bolt in nut, the both sides of described bolt end stop in Swing Arm 2 along its rotation direction, by bolts and nuts fit structure, realize the effect of first and

second positioner

6,7 fine position.
