Abstract

The utility model discloses a screw positioning device. The screw positioning device comprises a device main body and a clamping nut, wherein the clamping nut is screwed at one end of the device main body. The screw positioning device is a product which is simple and convenient, easy to use, and flexible and convenient in application occasions: installation of metal and nonmetallic screws, operation situation in a narrow space with inconvenience in manual operation, and installation of magnetic and non-magnetic screws. The screw positioning device can be used for greatly improving the working efficiency of operators and plays a role in reducing the labor intensity of the operators, thus having greater practical value.

Description

The screw positioner

Technical field

The utility model belongs to industrial design, particularly a kind of screw positioner.

Background technology

The general step that the operator uses screwdriver to tighten screw is: be enclosed within spring washer, plain washer on the screw successively earlier; Arresting screw external member (comprising plain cushion and bullet pad) holds screwdriver on the other hand; The screw external member is held up, use screwdriver, make screw type being screwed into of screw accomplish assembling process in the nut through spinning movement.Careless slightly screw will be scattered in this process, needs the above process of repetition, and operating efficiency is too low.As everyone knows, when screw is magnetic material (carbon steel material), use magnetic screw driver can adsorb the ordinary carbon steel screw, because screw is held screw difficult drop-off in the process of use screwdriver mounting screw by magnetic screw driver.For non magnetic (like stainless steel, copper product etc.) screw; Magnetic screw driver but can not adsorb, and needs a kind of instrument of locating non magnetic screw for the occasion of using the nonmagnetic substance screw, makes the screw difficult drop-off in the process of mounting screw; The convenient installation increased work efficiency greatly.

The utility model content

The purpose of the utility model is to provide a kind of screw positioner; Can be used for normal screws cutter and magnetic screw driver; Through using this device that screw (comprising magnetic and nonmagnetic substance) is positioned at the screwdriver end; Screw difficult drop-off in the use improves operating efficiency, has very high practical value and marketing prospect.

The technical scheme that realizes the utility model purpose is: a kind of screw positioner, comprise apparatus main body, binding nut, and binding nut screws at apparatus main body one end.

The utility model compared with prior art; Its remarkable advantage is: easy to be easy-to-use; The product that use occasion is flexible can be used for various industrial occasions and civilian occasion: the installation of operation occasion, magnetic and non magnetic screw in the installation of metal and nonmetal screw, the small space of inconvenient bimanualness.Use the utility model can improve operator's operating efficiency greatly, reduce the effect of labor intensity of operating personnel, have bigger practical value.

Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment

In conjunction with Fig. 1, Fig. 2 and Fig. 4, the utility model screw positioner need solve two fixation problem: the first, and positioner and screw fixing; The second, fixing of positioner and screwdriver comprises apparatus main body 2, binding nut 3, and binding nut 3 screws at apparatus main body 2 one ends.Wherein, positioner main body 2 is processed into tubular structure, has breach on the circumference at two ends, and wherein an end is processed into the little shape of the big opening of inner chamber, and clamped screw 1 is put into this end inner chamber; Screw thread is set on the other end external cylindrical surface and binding nut 3 screws, screwdriver 4 heads are put into from the other end of positioner main body 2 and are withstood on screw 1 head recess.Wherein, apparatus main body 2 screws the end with binding nut 3 and is processed into the circular cone lozenges.The middle part of apparatus main body 2 is provided with convexity, increases the intensity of part.

In conjunction with Fig. 3, the end inner cylinder face machining internal thread that the binding nut 3 and the apparatus main body 2 of the utility model screw positioner screws, other end inner cylinder face is processed into the circular cone lozenges, and external cylindrical surface processing annular knurl or polygonal shape are convenient to tighten.

Screwdriver 4 heads insert apparatus main body 2 endoporus from the right side during work; Binding nut 3 screws on the external screw thread of apparatus main body 2 right-hand members; Pressure through lozenges when screwing makes positioner main body 2 as a whole with screwdriver 4 combinations, avoids in use separating with screwdriver 4 causing inefficacy.

Positioner adopts stainless steel round bar turning processing, becomes the little shape of the big opening of inner chamber in the end machining of positioner, evenly has thin breach at circumferencial direction, utilizes the strain of material to step up screw.When head of screw was filled in positioner, positioner outwards enlarged, screw rod position size decreases behind the inner big cavity of head of screw access to plant, and screw is blocked in the material resilience.The pipe shape is processed in the other end of positioner, on the pipe circumference, has thin breach, and the part inner cylinder face is enclosed within on the screwdriver rod; External cylindrical surface threading, end machining become the circular cone lozenges.With supporting swivel nut of stainless steel round bar processing, swivel nut is a tubular structure, inner cylinder face one end machining internal thread, and other end inner cylinder face is processed into the circular cone lozenges, external cylindrical surface processing annular knurl.The screwdriver head inserts in the positioner main body endoporus during work, and the screwdriver head withstands in the screw head recess, realizes the axial limiting of screw in positioner.Swivel nut screws on positioner main body external screw thread, and it is as a whole that the pressure through lozenges when screwing combines positioner and screwdriver, avoids in use separating with screwdriver causing inefficacy.
