Abstract

The utility model provides a high thrust point bench clamp which comprises a bench clamp track, a fixed jaw and a movable jaw, wherein the fixed jaw is fixed on the bench clamp track; the movable jaw is mounted in the bench clamp track in a sleeving manner; the movable jaw is connected with a jaw thrust unit; the movable jaw is pushed by the jaw thrust unit to slide on the bench clamp track, and the force bearing point on the movable jaw pushed by the jaw thrust unit is higher than the matched surface of the movable jaw and the bench clamp track. Through the manner, and according to the force analysis of the movable jaw during the using process, the phenomenon that nonuniform stress at the upper part and the lower part of a sliding working surface of the movable jaw is avoided, the stress condition of the movable jaw is balanced, the working precision of the bench clamp is improved, and the service life of the bench clamp is prolonged at the same time.

Description

A kind of high thrust point bench vice

Technical field

The utility model relates to mechanical clamp design field, particularly relates to a kind of high thrust point bench vice.

Background technology

?the structure of bench vice is mainly to have movable vice body, the fixing part such as vice body, base.Movable vice body is arranged on fixedly on vice body, and movable vice body is driven and fixedly in vice body groove, moved by a screw mandrel that has a trapezoidal thread, from but can make the jaw can folding.Fixedly vice body is connected on base, and base is bolted on vice bench.The impetus of movable vice body and screw mandrel selects to have very large research, in common bench vice, the junction of screw mandrel and movable vice body is positioned at the below of movable vice body slip working face, and adjustable clamp is when holding workpiece, be positioned at the top of slip working face with the stress point of workpiece, so just easily form a turning torque, thereby can to bench vice, cause the injury of unbalance stress, reduce its service life.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of high thrust point bench vice, and it is reasonable in design, simple in structure, has solved the phenomenon of moving jaw unbalance stress.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of high thrust point bench vice, and it comprises: bench vice track, determine jaw and movable clamp port, determine jaw and be fixed on bench vice track, movable clamp port is set in bench vice track; On described movable clamp port, be connected with jaw thrust unit; The promotion that described movable clamp port is subject to jaw thrust unit is slidably on bench vice track, and the tie point of jaw thrust unit and movable clamp port is as stress point, and the position of stress point is higher than the mating surface position of movable clamp port and bench vice track.

Preferably, the described working face of determining jaw and movable clamp port is provided with inserting of auxiliary clamp.

The beneficial effects of the utility model are: a kind of high thrust point bench vice is provided, according to the force analysis of movable clamp port in actual use procedure, solved the phenomenon of movable clamp port slip working face bearing up-down force inequality, balance the stressing conditions of movable clamp port, improve the operating accuracy of bench vice, also increased the working life of bench vice simultaneously.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of high thrust point of the utility model bench vice;

Fig. 2 is the structural representation of the high thrust point bench vice of hydraulic transmission mode;

In accompanying drawing, the mark of each parts is as follows: 1, bench vice track; 2, determine jaw; 3, movable clamp port; 4, jaw thrust unit; 5, insert; 6, hand screw rod; 7, sour jujube bar; 8, limited block; 9, stress point.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to accompanying drawing 1 and Fig. 2:

A high thrust point bench vice, it comprises: bench vice track 1, determine jaw 2 and movable clamp port 3, determine jaw 2 and be fixed on bench vice track 1,3 mouthfuls, moving pincers are set in bench vice track 4; On described movable clamp port 3, be connected with jaw thrust unit 4; The promotion that described movable clamp port 3 is subject to jaw thrust unit 4 slidably on bench vice track 1, and the position that is subject to the stress point 9 that jaw thrust unit 4 promotes on movable clamp port 3 higher than movable clamp port 3 the mating surface position with bench vice track 1.What the described working face of determining jaw 2 and movable clamp port 3 was provided with auxiliary clamp inserts 5.

As Fig. 1, in this embodiment, adopt hand screw rod 6 to promote movable clamp port 3 and slide on bench vice track 1,9 mating surfaces higher than movable clamp port 3 and bench vice track 1 of stress point on movable clamp port 3, make movable clamp port 3 stressed evenly.

As Fig. 2, in this embodiment, adopt sour jujube bar 7 and limited block 8 to coordinate, movable clamp port 3 rear side mounting limit pieces 8, the tie point of limited block 8 is the stress point 9 of movable clamp port 3, and stress point 9 is the mating surface with bench vice track 1 higher than movable clamp port 3, limited block 8 forms drive connection with the sour jujube bar 7 of its below, has also ensured the uniform stressed of movable clamp port 3.

The utility model provides a kind of high thrust point bench vice, according to the force analysis of movable clamp port in actual use procedure, solved the phenomenon of movable clamp port slip working face bearing up-down force inequality, balance the stressing conditions of movable clamp port, improve the operating accuracy of bench vice, also increased the working life of bench vice simultaneously.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
