Abstract

The utility model relates to a tool for a bolt, in particular to a bolt tool applied to a vehicle door hinge bolt of a while vehicle, aims to solve the problem that in the production process of the vehicle, the installation of the vehicle door hinge bolt of a while vehicle body is excessively slow so as to influence the assembling and adjusting speed of the while vehicle body and processes of other working procedures and provides a bolt tool, which not only can fasten the tightening speed of the vehicle door hinge bolt, but also can improve the installation quality. The bolt tool mainly consists of a screwing tool head and a crank. The tail part of the screwing tool head is embedded at one end of a handle. The screwing tool head is a screw driver head. The bolt tool has the advantages of simple structure, easy processing, convenient operation and labor saving.

Description

The bolt instrument

Technical field:

The utility model relates to a kind of hardware ﹠ tools, specifically, relates to a kind of bolt instrument that is applied to white car body hinge bolt.

Background technology:

In the auto-producing process, the car door of body in white is debug extremely important, is directly connected to whole auto-producing rhythm of production and efficient.And the main factor that influences the speed of debuging of white car car door is the installation of white car body hinge bolt, the peripheral movable space of white car body hinge bolt is limited, when hinge bolt being installed with general instrument, waste time and energy, and quality can not get ensureing, usually therefore cause the speed of debuging and the quality of white car car door to can not get ensureing, thereby have influence on postorder assembling and production, cause economic loss to enterprise.

By retrieval, it is the patent of CN2281872Y that Patent Office of the People's Republic of China discloses a part notification number on May 20th, 1998, and name is called: the hand bolt tensioner.Its structure is by torque arm, movement weight rod and box spanner constitute, there is the collision block dish of a band through hole and cavity in movement weight rod central authorities, the torque arm two ends are respectively round end and square toes, the torque arm middle part is provided with the collision block body, the torque arm round end passes the collision block dish of movement weight rod, torque arm and movement weight rod constitute cross, the collision block body of torque arm is provided with the fan-shaped collision block of evagination of symmetry, be provided with the trapezoidal collision block of convex of symmetry in the collision block dish of movement weight rod, fan-shaped collision block and trapezoidal collision block cooperation are intersection setting, the square toes of torque arm put box spanner, come the driven rotary cylinder wrench by the rotation movement weight rod like this, thereby realize the degree of tightness of bolt, can select corresponding box spanner according to bolt.This hand bolt tensioner structure is complicated, is difficult for making, and particularly the fit structure between collision block body and the collision block dish in use, has wearing and tearing between collision block body and the collision block dish, needs to change after long-time the use.

Summary of the invention:

The purpose of this utility model is to solve: in the automobile production process, because of the speed of debuging of body in white and the process of other operation of influencing slowly crossed in the installation of the body hinge bolt of body in white, provide a kind of bolt instrument not only can accelerate the speed that tightens of body hinge bolt but also can improve installation quality, debug speed thereby accelerate body in white, avoid having influence on the process of other operation.

The technical solution of the utility model: a kind of bolt instrument, it mainly is made up of rotating tool head and crank, crank is divided into three part starting handles, rocking arm and handles, the tail end of rotating tool head is embedded in the sleeve pipe on starting handle top of crank, the head of rotating tool head is a driver bit, driver bit is corresponding with bolt, like this bolt instrument just can realize at a distance, the labour-saving construction bolt, save time simultaneously.

The tail end of described rotating tool head is the polygon cylinder, sleeve pipe of top welding of described crank starting handle, the inside pipe casing structure is the polygon cylinder, the tail end structure of the internal structure of sleeve pipe and rotating tool head matches, make the rotating tool head tail end can be embedded in the sleeve pipe of starting handle, can block rotating tool head during the sleeve pipe rotation, make rotating tool head can follow the crank starting handle and rotate together.Make the bolt instrument that the bolt of different size can be installed by using instead of rotating tool head.

Described crank is the Z font, and crank can one-time cast-forming, or a few part is welded, or is formed by a round steel bending.

Handle of the handle tail end of described crank welding, handle help that hand grips and the crank suspension is put, and make easy to operately, and handle can be structures such as circular, triangle ring-type.

The starting handle outside of described crank is with a cylinder hollow cylinder, and hollow cylinder auxiliary starter bar rotates, and the friction to starting handle when minimizing is hand-held hinders, and makes more convenient to operate.

The beneficial effect that the utility model is obtained:

Simple, convenient, avoid the small space around the bolt, the transmission by power makes opereating specification become wide, the use that adds upper rocker arm can be laborsaving; Flexible operation can be changed corresponding rotating tool head and get final product according to the specification of bolt.

Fig. 2 is the schematic top plan view of the crank of a kind of preferred embodiment of the utility model bolt instrument.

Fig. 3 is the schematic diagram of the rotating tool head of a kind of preferred embodiment of the utility model bolt instrument.

Fig. 4 is the schematic diagram of a kind of preferred embodiment duty of the utility model bolt instrument.

Among the figure: 1, rotating tool head, 11, driver bit, 12, the screens body, 2, crank, 21, sleeve pipe, 22, starting handle, 23, rocking arm, 24, handle, 25, handle, 3, the cylinder hollow cylinder.

The specific embodiment:

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Embodiment: a kind of bolt instrument is participated in accompanying drawing 4, comprises rotating tool head 1, crank 2, cylinder hollow cylinder 3.The tail end of rotating tool head 1 is embedded in the top of crank 2, and is with cylinder hollow cylinder 3 in one section outside of crank 2.

Among Fig. 1,2, the crank 2 of bolt instrument comprises starting handle 22, rocking arm 23 and handle 24, starting handle 22, rocking arm 23, handle 24 are integral successively, and be the Z font, at sleeve pipe 21 of the top of starting handle 22 welding, sleeve pipe 21 internal structures partly are the polygon cylinder, match with the screens body of rotating tool head 1.Triangle handle of tail end welding at handle 24 grips during convenient work, and cylinder hollow cylinder 3 is enclosed within outside the starting handle 22.

The head of rotating tool head 1 is a driver bit 11 among Fig. 3, and the bolt when driver bit 11 is standard components with work is corresponding, and the screens body of rotating tool head 1 tail end is the polygon column structure, matches with the internal structure of the sleeve pipe 21 on crank starting handle 22 tops.

When using, select suitable rotating tool head 1 according to bolt, and the screens body of rotating tool head 1 is positioned in the sleeve pipe 21 on crank starting handle 21 tops, again cylinder hollow cylinder 3 is enclosed within the outside of starting handle 22, top with rotating tool head 1 is enclosed within on the bolt then, left hand is held cylinder hollow cylinder 3, and the handle 25 that the right hand is held on the crank 2 just can swivel bolt, carries out the installation and removal of bolt.
