Abstract

The utility model discloses a handheld automatic screw-driving machine structure which at least comprises an electric screw driver, a cylinder and a set of clamp jaw structure, wherein the electric screw driver is used for driving screws, and the clamp jaw structure is used for transferring screws; and the handheld automatic screw-driving machine structure is characterized in that a handheld part of the electric screw driver is connected with a cylinder which is parallel to the axial line of the electric screw driver by a connecting component, the retractable end of the cylinder is connected with a clamp jaw part in a sliding manner by a shaft pin and a spring, the clamp jaw part comprises the connecting component, a clamp jaw seat, a screw conduit, a holding sleeve and a locking sleeve and the like, and the locking sleeve is internally provided with a stop dog (for clamping screws) and an elastic ring. By using the handheld automatic screw-driving machine structure disclosed by the utility model, the conveying and positioning of screws can be automatically completed; and the handheld automatic screw-driving machine structure is simple in structure, convenient and practical.

Description

Hand-held automatic locking filature structure

Technical field

The utility model relates to a kind of light instrument of usefulness of universal hand-held automatic locking screw, be a kind of can replace common electric screwdriver and than electric screwdriver more efficient and labour-saving automatic locking filature, especially more can demonstrate its superiority for the nonferromagnetic screw.

Background technology

No matter be household electrical appliances or electron trade at present; Realize that with the screw union piece assembling of product still is one of main technique of production; General common electric screwdriver is at present transformed various in the market hand-held automatic locking filatures have just been arranged for improving efficiency of assembling; The principle of these hand-held automatic locking filatures is essentially identical, has both used the screw feeding system, adds the dop part at the electric screwdriver head; By feeding system screw is delivered in the dop, realized resetting of dop with spring force.Though these structures have solved the problem of sending screw automatically; Can raise the efficiency, but want the operator manually to overcome the spring force that dop partly moves up and down, increase extra load and consumed more muscle power; So remain not labour-saving instrument of province's merit, thereby influenced further popularization.

Novel content:

The utility model provides a kind of hand-held automatic locking filature of merit but also labour-saving of not only having economized; It includes an electric screwdriver that is used for locked screw at least; A cylinder and a cover are met and sent off the dop structure of screw, it is characterized in that: connect a cylinder with the electric screwdriver parallel axes at the handgrip part of electric screwdriver through connecting elements, at pivot pin of flexible end connection of cylinder; Be with spring on the pivot pin; Pivot pin and dop partly adopt and are slidingly connected, the applying that dop part can be relatively moved with pivot pin and keep pivot pin and dop part with spring force, and dop partly is made up of connector, dop seat, screw conduit, maintainance set and lock sleeve etc.; Lock sleeve is connected with dop seat bottom; Be useful on block and the elastic ring of clamping screw in the lock sleeve, the annular that block is made up of the arc piece of two above circular cross-sections, the annular outer ring is with elastic ring.

During operation to be power with compressed air drive dop through cylinder partly moves up and down and accomplishes screw feeding and location, and cylinder contacts the slot-open-section of screw and withstand with the screwdriver bit tip when top dead center position.This structure can not produce extra duty power when lock is paid, the screw contact workpiece can not withdrawn, and because screw exposes and can make things convenient for the alignment function position, transfers electric screwdriver torsion the same with original electric screwdriver convenient with the replacing screwdriver bit.

Description of drawings

Fig. 1: the three-dimensional structure diagram of the utility model;

Fig. 2: the front section view of the utility model (treating lock pair state);

Fig. 3: the front section view of the utility model (feeding state);

Fig. 4: the position enlarged drawing that the dop of the utility model is concrete;

Fig. 5: the three-dimensional exploded view of the utility model.

Wherein: 1 electric screwdriver, 2 connecting elements, 3 cylinders, 4 springs, 5 pivot pins, 6 connecting plates, 7 lock sleeves, 8 screws, 9 dop seats, 10 screw conduits, 11 screwdriver bits, 12 blocks, 13 elastic rings, 14 maintainance sets.

The specific embodiment

Like Fig. 1, shown in Figure 5: fixing electric screwdriver connector 2 on common electric screwdriver 1 connects a cylinder 3, cylinder and electric screwdriver 1 keeping parallelism in the ear of electric screwdriver connector 2 with screw; The extension of cylinder connects a pivot pin 5, the height and position of the nut adjustable axle pin 5 that carries through cylinder, and pivot pin and dop connecting plate 6 are slidingly connected; Keep dop position partly through spring 4; Dop part is by dop seat 9, screw conduit 10, and lock sleeve 7 is formed with block 12 and elastic ring 13.

Send the screw state: see Fig. 3, cylinder stretches out, and dop leaves screwdriver bit 11; Through screw conduit 10, the Y type hole of dop seat 9 gets in the dop screw 8 through feeding system, screw 8 heads is blocked and the centering location by rounded block 12; Then cylinder 3 shrink the up drive screw 8 of dops make it to screwdriver bit 11 places with screwdriver bit 11 touching positions in treating the lock state; See Fig. 2, because the dop project organization is very shallow, screw 8 bar portions can expose mostly; Can aim at lock as common electric screwdriver and pay the switch of pressing electric screwdriver 1 in the position and lock and pay this moment; The dop end face contacts with workpiece when screw 8 is locked into certain depth, and under the coupling mechanism force effect of screw, dop overcomes the elastic force of spring 4 and retreats automatically and screw 8 is discharged to accomplish lock pair work.

Lock pay to be accomplished, and after electric screwdriver stopped the rotation and lifts, cylinder stretched out and drives dop and carry out feeding next time.

The utility model is simple in structure, and reality is locked when paying the same with common electric screwdriver, and screw is not withstood and can be withdrawn by screwdriver bit, does not increase extra load force, and can aim at lock easily and pay a position, and accent electric screwdriver torsion is the same with original electric screwdriver convenient with the replacing screwdriver bit.

All to pay the position shape relevant with the specification of screw and lock for the stroke that the structural factor of the utility model comprises cylinder; The above is a preferred embodiment of the utility model; Under the situation that does not break away from the utility model inventive concept; Any conspicuous distortion and the replacement carried out all belong within the utility model protection domain.
