Abstract

The utility model belongs to the field of mechanical tools. The existing table vices can only rotate in the horizontal plane, the angle of the work piece needs to be transformed in the vertical plane when processed, and the position of the work piece can not be clamped suitably. The utility model divides the table vice seat and the table vice claws which are linked as integration into two parts; the table vice claws are contained in the circular hole of the table vice seat in a clearance fit, connects the sliding claw to the inner block of the inner wall of the other claw, makes the two claws rotary and motionless together in all directions in the space, and enlarges the functions of the two claws effectively. The utility model can process the components in complicated external shapes and grind various angles with the use of small-size tool grinding machine.

Description

Universal vise

The utility model relates to the machine tool field.

What used in the manual work place at present is a kind of bench vice of mainly being made by cast iron, be clamped in during use on chopping board or the table, the clamping device that caliper can rotate arbitrarily in the horizontal direction, weight is about five kilograms, is a kind of, file, saw whole to miniature parts, the aid that grinds, must use during bench work such as line assembling.Be usually used in occasions such as the light maintenance, making of family, auxiliary soldering again.Therefore in most manufacturing works and the part family use is arranged all, the small shop that repairing and five metals are made uses more general.Along with the expansion of plant produced, the increasing of the increase of repair service industry and household electrical appliance, engineering goods, its demand constantly increases.

But existing product exists weak point: (1) is heavy; (2) underaction.Its caliper is on the horizontal direction all the time, can not satisfy the clamping needs on other direction, can only unload workpiece mounting board again, does not guarantee required angle.

In order to adapt to manual processing better to the miniature parts of external form complexity, satisfy the needs that general homecraft is repaired and teen-age invention is created, designed the utility model.

Its caliper of existing product only can rotate and static in the horizontal direction, feature of the present utility model its caliper can not only be in the horizontal direction also can vertical plane in arbitrarily angled rotation and static.

One of its two pawl of existing product is cast as one with pincers seats, and feature of the present utility model is that its corresponding pawl separates its cover shape and partly is contained within the circular hole of pincers seat with the pincers seat.Above-mentioned two cooperation places are matched in clearance.In the tangent line partial design of its mating holes circumference a cross-drilled hole, in the hole with one slidably, wedge key that can be fastened connects, an end of key is included in the cross-drilled hole, the other end is wedged this pawl and is contained part along in the groove of outer circular direction.

The sliding jaw of existing product is connected in the dovetail groove of pincers seats part, of the present utility modelly is characterised in that sliding jaw is connected in and is fastened on another pawl inwall place, connects in the guide-track groove on the locating piece of feed screw nut.

The threaded portion of the feed screw nut of existing product is complete, the utility model is for adapting to the confined space in the sliding jaw, its feed screw nut is for cutting the half-nut more than 1/2nd along its axis of thread direction, and the threaded portion that can embed leading screw under the effect of pin plate and spring becomes to screw state or breaks away from leading screw with it, is free state.

The utlity model has following advantage:

(1) overall size is not more than the same specification existing product, and weight saving is about 40 percent, and chucking power reaches more than 90 kilograms, satisfies general bench work needs fully.

(2) function of use improves a lot, whether its holding workpiece all can stopped by optional position in horizontal plane and the solid space that square crossing becomes, and can make workpiece rest on the optimum position according to the angle index on it, greatly facilitate the manual processing and the part location such as soldering, small power electric gas welding of the parts such as model of multiple complex contour.As increase simple fastening annex and be fixed on the workbench of small instruments and tools grinding machine, but the various angles of grinding.

(3) can realize unloading fast and live and, improve work efficiency according to gripping object size its jaw distance of change rapidly.

Description of drawings is as follows:

Pincers seat (6) (see figure 1) is connected on the medium base (12).(7) be fixed claw, one end cover shape partly is contained within the hole of pincers seats (6).Be matched in clearance, connect with a wedge key (10) (see figure 2), wedge key (10) is microscler nut one an end mill wedgewise, wedging fixed claw cover shape part is along in the groove of outer first direction, its wedge surface and groove bottom are coincide, with the groove both sides be matched in clearance, under the effect of bolt (5), can unclamp and fastening fixed claw (7), and prevent its play vertically.Moving jaws (9) is welded on the slip cap (8), and along the length direction an opening is arranged at the bottom of (8), inserts in the pair of guide rails groove of locating piece (1).Locating piece (1) is fixed by bolts in the inwall of fixed claw (7) cover shape part.Locating piece (1) is connected to a relatively independent integral body to fixed claw (7), moving jaws (9), leading screw (4) and mother lead screw (3) like this, realizes the arbitrarily angled rotation of its jaw in vertical plane.

Because the confined space in the slip cap (8), mother lead screw (3) is designed to half-nut, has a cross section to be circular lead below it, stretches in the corresponding hole of locating piece (1).A groove is arranged along its length at the bottom of locating piece (1), puts the pin plate (2) that can advance and pull out certain distance.Under the effect of compression spring (11) (see figure 2) of pin plate (2) and feed screw nut (3) side, nut (3) can move axially along lead and embed or break away from leading screw (4).

Locating piece of the present utility model (1) needs to adopt the higher cast iron manufacturing of intensity, can adopt smart casting back reprocessing during batch process.Can bend by hand during pin plate (2) trial-production, batch process can be adopted punching press.Feed screw nut cuts from the threaded portion after also need adopting wear resistant cast iron once to make two.Leading screw (4) adopts 45# steel car system, also can adopt cold rolling when big in batches.Screw rod (5) is implemented identical with leading screw.Pincers seats (6) adopt cast iron HT21-40, reprocessing hole, smart casting back.It is a matched in clearance with cooperating of fixed claw (7).Fixed claw (7) can be made cover and pawl two parts earlier, stays fine finishining again after the allowance welding.General arc welding can be adopted during trial-production, the pressure electric resistance welding can be adopted when producing by batch.The available tubing of slip cap (8) is made, and with the breach of moving jaws (9) welding back in processing its underpart, aligns to guarantee two chela clampings.Moving jaws (9) time can bend by hand in trial-production, but punch forming in batches the time.Wedge key (10) is made long nut earlier, at one end mills wedgewise then, and its threaded portion can screw with screw rod (5).The available carbon spring steel of spring (11) is removed the internal stress tempering after bending by hand.
