Screw bolt driver for fastening {A SCREW BOLT DRIVER FOR LOCKING WORK}

The present invention relates to a screw bolt driver for fastening, and more particularly, to the provision of a driver suitable for assembly-type industrial work by providing an improved configuration, particularly a screw driver.

Various shapes and types of small tools such as screwdrivers or wrenches are widely used throughout the industry.

Most of these screwdrivers or wrenches have sizes and shapes that can be used for assembly work, such as machine assembly work, by locking and unlocking operations, and are manufactured and sold commercially based on standardized tip shape, size, and strength. .

However, in addition to these universally produced and sold drivers and wrenches, work in a specific industry, for example, clamping and releasing the tip or clamper of a processing machine, repetitive assembly work of a specific machine, chucking or cutting in a lathe Bites and bits replacement work, assembly work of semiconductor equipment, and assembly work of various special machines are mainly assembly configurations in which screws are fastened by providing between coupling members to be fastened, and assembly employing screw bolts for the specific purpose described above. The task "screw bolt driver for tightening" is being requested.

As an example of the 'fastening work' referred to in the present invention, in the case of replacing a chuck or replacing a cutting byte on a lathe, the main shaft and a number of adjacent driving members are assembled in a narrow space and are universally manufactured. The drivers sold are extremely difficult to use.

In addition, even when assembling a dedicated machine such as a semiconductor device, precise driver operation work for assembling in a very narrow space with severe interference between other parts requires effort and pain from the operator.

In view of these problems, screwdrivers for fastening have been used for specific tasks in the past, and most fastening screw bolt drivers are insert-injected integrally into the handler, which is a small handle equipped with a driver tip or wrench tip, to produce a large amount. produced and provided.

The screw bolt driver for fastening of the above method;

(1) Its size should be relatively small, so it should be easy to use in a narrow assembly space,

(2) The production cost should be low so that economic losses are minimized even in the case of repetitive work and loss in a narrow work space.

(3) If necessary, it should be economical enough to be provided together with a considerable amount of service items together with finished mechanical products (lathes, dedicated machines),

(4) Due to the nature of the service work of assembling processed steel parts as screw bolts,

In the initial entry stage of the screw bolt, which requires almost no tightening torque, it is possible to enter the screw thread quickly, and at the final position of the screw bolt's thread entry, a considerable amount of tightening torque can be applied, so that the end of the screw bolt entered is assembled. Conditions must be satisfied that strong fastening between metal parts can be performed with a high pressing force into the threaded end of the target part.

The screw bolt driver (SD) of the present invention, as in the preferred optimal embodiment of FIG. 1 or less,

Driver tips 10 of various shapes suitable for the head of the screw bolt to be fastened are provided as metal-processed tip bodies in the same form as in the prior art, and are integrally molded with the driver tip 10 or inserted as replacements as described later. It is provided with a handle holder (Handle Holder: 100) as a handle part.

The handle holder 100 may be made of a synthetic resin injection molding body having relatively high strength, an aluminum sintered body, or an aluminum press-processed body. In the case of a synthetic resin injection molding body, the driver tip 10 is manufactured by insert injection into a tip hole (not shown). And, in the case of materials such as aluminum, it will be press-fitted by being inserted into the provided tip hole.

As the handle holder 100 is also shown in FIGS. 1 and 3 below,

As a basic body part, a power paddle (110), which is a knob shape part,

It is composed of an approximately rectangular plate body having an extended rod-shaped quick pole (130) protruding from the power paddle 110 on a straight axis to which the driver tip 10 is mounted and molded into an integral body.

As shown, the power paddle 110 is integral with the tip body 140, which is an insertion body into which the driver tip 10 is inserted along the axis C, and is perpendicular to the axis C of the driver tip 10. It is a plate-shaped knob-shaped body that is extruded.

Accordingly, the handle holder 100 constitutes a substantially rectangular plate-like body having a thin overall thickness when viewed from a plan view.

On the opposite side of the power paddle 110, which is a plate-shaped portion extending from the tip body 140 along the direction perpendicular to the axis line C of the driver tip 10, the hinge paddle (Hinge Paddle: 120) also protrudes as a plate-shaped portion is extended

The power paddle 110 constituting the handle holder 100 is a grip indent 116, 116' in which the central part of the plate surface is indented, and is formed as a curved body indented on both sides of the plate. It is desirable to increase the frictional force and improve the grip feeling when gripped by the operator's fingers.

More preferably, one or more grip lines 117 and 127 that increase frictional force as long protrusions are formed on the power paddle 110 and the hinge paddle 120, respectively, in order to improve rotational frictional force.

In accordance with the technical idea of the present invention, the outwardly extending widths (lengths) of the power paddle 110 and the hinge paddle 120 constituting the handle holder 100 are configured differently.

That is, the extension width L1 of the driver tip 10 of the power paddle 110 from the axis C is the extension width L2 of the hinge paddle 120 extending to the opposite side of the power paddle 110. It has a larger value, and preferably has a length of the width (L1) of about 0 to 10 times the extension width (L2) of the hinge paddle 120. When the length of the extended width L2 of the hinge paddle 120 is 0, the hinge paddle 120 is not provided, and the same effect is obtained even in this form.

The action and reason for the configuration of the power paddle 110 and the hinge paddle 120, which are plate-like parts extending from the tip body 140 to both ends, will be described later.

As shown, the top of the drawing of the power paddle 110 and the hinge paddle 120, that is, the top surface of the opposite side of the driver tip 10 to both sides where the quick pawl 130 is formed,

The power paddle indent 115 of each different power paddle 110 and the hinge paddle indent 125 of the hinge paddle 120 are configured as curved portions, respectively, and the power paddle indent 115 has a curvature (R1), the hinge paddle indent 125 becomes a surface upper body having a different curvature (R2).

Although the reason for the construction is clear in the use of the screw bolt driver (SD) of the present invention described later, the curvature (R1) of the power paddle indent 115, which is the top surface of the power paddle 110, is the standard Korean thumb end The curvature of the hinge paddle 120, the curvature (R2) of the hinge paddle indent 125, which is the upper surface of the hinge paddle 120, is configured as a part of the curved surface that almost matches the curvature of the index finger end of the standard Korean, so that each rounded surface have

By configuring as described above, when a worker wears work gloves or works with bare hands, the quick pole 130 is used as the end of the thumb and index finger for rapid rotation of the screw bolt driver SD, and the power of the power paddle 110 By connecting the paddle indent 115 and the inner curved surface of the hinge paddle indent 125 of the hinge paddle 120, stable gripping is possible.

It serves to extremely facilitate the rotation of the entire screw bolt driver (SD) during fast rotation fastening using the quick pawl (130) of the screw bolt driver (SD).

An indent surface having the same curvature may also be formed on the opposite side of the connection portion of the power paddle 110 of the handle holder 100 and the quick pawl 130 of the hinge paddle 120, but this is not necessary.

In FIGS. 1 to 3, the planar quadrangular recessed area (N) of the outer surface of the tip body 140 is a name plate portion that allows information such as the size or shape of the screw bolt driver (SD) to be etched or a sticker attached. is used as

As the quick fall 130 is shown in FIG. 1 below,

It is a rod-shaped body that is integrally molded with the handle holder 100 and extends to the rear end along the axis C of the driver tip 10, and a plurality of protruding liner lines 131 are formed on the outer periphery 131 as protruding lines. It is integrally molded, and the liner line 131 provides frictional force when the quick pawl 130 grips and rotates to enable smooth rotation.

As the liner line 131 is exemplarily shown in FIG. 6,

The longitudinal section of the quick pole 130 forms a grip face 132 having a plurality of indented friction surfaces in a star, polygonal shape, etc., and a knurled face 133 with a kurling shape on the outer periphery. Friction can be improved there is.

The use and operation of the screw bolt driver (SD) for fastening of the present invention will be described.

As shown in a of FIG. 4, the members (A) and member (B) of the machine of the exemplary assembly object made of a material such as metal each have screw bolt holes (a, b) and screw bolt holes (a, b). The fastening operation with the screw bolt (S) will be described.

At the beginning of fastening, which enters the screw bolt hole (a) located ahead, the thread on the inner surface of the screw bolt hole (a) and the thread of the screw bolt (S) form a surface with almost no friction due to the influence of the design inner diameter and working oil. are doing

In this state, as shown in b of FIG. 4, the operator rapidly rotates only the quick pole 130 of the screw bolt driver SD using the thumb and forefinger, so that the screw bolt S passes through the screw bolt holes a and b. Enter quickly and enter into the contract.

When the fastening end Be of the screw bolt S approaches the entry end be of the screw bolt hole b, For further fastening, the turning force of the screw bolt driver (SD) of considerable torque is required.

At this time, as shown in b of FIG. 5, the operator quickly moves his finger toward the handle holder 100 and connects the index and middle fingers to the hinge paddle 120 to move the hinge paddle 120 to the hinge point H. When force is applied by twisting the power paddle 110 with the thumb, the fastening end (Be) of the screw bolt (S) enters the terminal end (be) of the screw bolt hole (b), thereby maximizing the fastening force and tightening It is completed.

In this process, when the quill pole 130 is gripped with the thumb and forefinger, the ends of the operator's fingers are located on the power handle insert 115 and the hinge paddle insert 125, enabling gripping as if wrapped naturally, and power When the paddle 110 and the hinge paddle 120 are held and operated by the fingers, the inner surface of the fingers adheres closely to the grip indent 116', so that the slipping phenomenon can be prevented while increasing the gripping feeling, and the operator's fingers Since the sense of difference and interference between the handle holder 100 and the handle holder 100 are excluded, it is possible to improve the fastening (unfastening and tightening) force.

When the screw bolt (S) is released from the screw bolt holes (a, b), it is natural that the handle holder 100 is operated in reverse to the above operation.

The above-described work is continuously performed by skilled workers in a narrow working space, so that the work is performed in a very short time, improving assembly workability, and enabling work in a narrow assembly space or fastening space.

As another modified embodiment, a tip holder hole (not shown) is formed on the end surface of the tip body 140 of the handle holder 100 so that various types and tip shapes of driver tips 10 can be exchanged from the handle holder 100. It is possible to form and provide replacement means such as insertion and fixation by frictional force or insertion and fixation by magnetic force such as a magnet.

There are only a few types of machines such as special machines for assembly or fastening manufactured by a specific manufacturer, and since these small number of machine types are repeatedly assembled and fastened, frequent driver tip 10 It is not necessarily necessary because replacement is not required and a screw bolt driver having a specific size and shape of the driver tip 10 is required.

Although the power paddle 110 constituting the handle holder 100 is made large and the opposite hinge paddle 120 is formed small, the power paddle 110 is placed on both sides of the quick pawl 130 It will also be possible to configure it in a protruding form, and in this case, it is possible to increase the operating force even if it is formed in a size smaller than the size of the power paddle 110 protruding to one side.

This is relative to the extension width (L1) from the axis line (C) when protruding the power paddle 110 to one side than the extension width (L1) from the axis line (C) when protruding the power paddle 110 to both sides. This is because the overall size can be made similar by making it smaller, but the operating force can be the same or larger.

Therefore, it is not limited to the shape and shape of the power paddle 110 and the hinge paddle 120 of the form exemplified in the present invention and may have various shapes and shapes, and the power paddle 110 and the hinge as needed A configuration in which the paddle 120 protrudes upward or downward is also possible.

In addition, the screw bolt driver (SD) of the present invention has a very low manufacturing cost due to its configuration, so that it can be easily discarded as a disposable tool when the driver tip 10 is worn out after repetitive work.
