Abstract

The invention relates to a bench vice which comprises a lead screw, a triangular wedge block, a T-shaped nut, a female jaw, a male jaw, an elastic cylindrical pin, a spring, a gasket, a spacer, a chassis, a side plate, a small jaw A, a U-shaped groove and a small jaw B. The bench vice is characterized in that the male jaw and the U-shaped groove are welded into a composite member I; the female jaw, the chassis and the side plate are welded into a composite member II; the small jaw B and the male jaw are welded into an integral structure; the small jaw A and the female jaw are welded into an integral structure; the lead screw is arranged in the U-shaped groove; the lead screw is arranged on the lower parts of the U-shaped groove and the male jaw and is fixed in the U-shaped groove by virtue of the elastic cylindrical pin; the lead screw is connected with the gasket by virtue of the spring in the U-shaped groove; the gasket is connected with the lead screw; the T-shaped nut is arranged in the chassis to form an integral member with the chassis; the triangular wedge block is arranged between the U-shaped groove and the side plate; and the figures of the small jaw A and the small jaw B are in an integral structure. The bench vice has the beneficial effects of small volume, strong clamping force, high precision and long service life, is never broken and is flexible to use.

Description

Bench vice

Technical field

The present invention relates to hardware & tools, a kind of specifically bench vice is widely used in the indispensable instrument of machine-building, Ship Building and Repairing, Mechanical Help, mine, metallurgical equipment maintenance field and pincers worker.

Background technology

Bench vice of the prior art is simple in structure, specification requirement is low; Generally all use castings production to make, its structural behaviour can not get fully playing, and is prone to phenomenon of rupture in the use; And volume is big, operation is dumb; Jaw is prone to loosening, and the clamping dynamics can not settle at one go, and service life is short.

Summary of the invention

Technical problem to be solved by this invention is the deficiency that overcomes prior art; A kind of bench vice is provided, and the technical scheme that invention solves its technical problem reason is: structure of the present invention comprises screw mandrel, triangle voussoir, T-nut, female jaw, public jaw, elastic cylindrical pin, spring, packing ring, pad, chassis, side plate, small forceps mouth A, U-lag, small forceps mouth B, it is characterized in that public jaw and U-lag are welded as sub-assembly one; Female jaw and chassis, side plate are welded as sub-assembly two; Small forceps mouth B and public jaw structure, small forceps mouth A and the female jaw structure that is welded as a whole that is welded as a whole is provided with screw mandrel in the U-lag, screw mandrel is arranged on U-lag and public jaw bottom; Screw mandrel is fixed in the U-lag through elastic cylindrical pin; Screw mandrel is connected with packing ring through spring in U-lag, and packing ring is connected with screw mandrel, and T-nut is arranged in the chassis and is integrated whole with the chassis; Be provided with the triangle voussoir between U-lag and the side plate, the jaw decorative pattern of small forceps mouth A and small forceps mouth B with caliper be overall structure.

The effect of main parts size is: screw mandrel: be installed in the U-lag and the public jaw bottom of sub-assembly one, be used for distance between the moved jaw, regulate the dynamics size of workpiece in clamping; Tightening adjuster: be installed in female jaw one side, be exclusively used in clamping precision and U-lag and female jaw V-shaped part fit clearance of regulating jaw; The triangle voussoir: be installed in an inboard filler of female jaw, having only has the effect of regulating degree of tightness to U-lag; T-nut: be integrated whole with the chassis, strengthened the pulling force and the precision of screw mandrel and screw, guarantee that chassis and screw mandrel can move stably; Female jaw: be welded on and form sub-assembly two on side plate, the chassis, the jaw decorative pattern of small forceps mouth A and small forceps mouth B with caliper be overall structure, never becoming loose,, never rupture; Public jaw: be welded to form sub-assembly one with U-lag, the jaw decorative pattern of small forceps mouth A and small forceps mouth B with caliper be overall structure, never becoming loose,, never rupture; Elastic cylindrical pin: spring on the screw mandrel of location and pad, packing ring guarantee moving steadily of sub-assembly one; Little jaw: be installed in a pair of V-arrangement folder mouth of jaw below, be exclusively used in the clamping of cylinder object; Chassis, side plate: side plate is welded on and is used to connect female jaw on the chassis; U-lag: the connection and the guide effect that are exclusively used in public jaw; Spring, pad, packing ring: be installed in and play smoothly effect smoothly on the screw mandrel, help the jaw expansion.

The technological process that the present invention makes is: 1, selected material: hot heading 45# steel (Cr-V); 2, hot forging: public jaw, female jaw, little jaw, U-lag, chassis, screw mandrel, base; 3, metalworking: Vehicle Processing: public jaw, female jaw, chassis, screw mandrel, base; Mill processing: public jaw decorative pattern, female jaw decorative pattern, U-lag, anvil; Mill processing: jaw, anvil, silk; Boring: public jaw, female jaw, chassis, screw mandrel; Tapping: female jaw; 4, heat treatment: public jaw, female jaw decorative pattern place (HRC45-50 high frequency); Anvil face: HRC45-50 high frequency; Little jaw: HRC40-45 salt bath; 5, welding processing (interior gravitation is eliminated in heating): public jaw and U-lag soldering group component one; Female jaw and chassis, side plate soldering group component two; Little jaw and the welding of public jaw, little jaw and the welding of female jaw; 6, cold drawn: corner block; 7, draw cut is cut: female jaw V-shape portion position; 8, assembling: screw mandrel, triangle voussoir, pad, spring, resilient key, tightening adjuster, weldment.

The invention has the beneficial effects as follows that volume is little, never fracture, chucking power is strong, uses flexibly, and precision is high, the life-span is long.
