Abstract

The utility model relates to a universal vice and comprises a fixed vice body, a movable vice body, a direction rotating disk, a bottom seat, a locking pulling rod, a locking screw rod and a locking screw nut. The lower parts of the vice bodies are the hemispheres, and the upper part of the direction rotating disk is a concave spherical surface. A locking mechanism composed of the locking pulling rod, the locking screw rod and the locking screw nut is used for locking or loosening the hemispheres and the concave spherical surface. When the locking mechanism loosens, the hemispheres can rotate on the concave spherical surface to cause the vice to arbitrarily regulate the angle of a vice port in a certain range of the three dimension. The requirement that a work component is processed at any angle through once clamping is met, and the universal vice has the advantages of simple and reasonable structure, high work efficiency, convenient use, etc.

Description

Toolmaker's vise

The utility model relates to a kind of vice of holding workpiece, belongs to machine tool component or hand tools.

Swinging vice commonly used at present can make jaw turn to the position of any needs in horizontal plane, its structure is mainly by base, rotating disk, moving caliper, moving jaw, leading screw, feed screw nut, fixed caliper, regular jaw, guide rail, the leading screw support is formed, one end of fixed caliper has regular jaw, the centre is a guide rail, the other end has the leading screw support, moving jaw is contained on the moving caliper, moving caliper is contained on the guide rail, feed screw nut is housed in the moving caliper, leading screw one end is contained in the feed screw nut, the leading screw other end passes the leading screw support and with cover and taper pin location, and rotating threaded shaft just can drive moving caliper and seesaw with clamping or unclamp workpiece between jaw.The bottom of fixed caliper is flatly to be connected with rotating disk, has installation gap to be fixed on lathe or the workbench with screw on the base of rotating disk bottom, and the position of rotational fixation caliper on rotating disk can make jaw turn to desired location on horizontal plane.But for also need be or the workpiece processed of front-back clamping again in the side, complex operation, the angle of clamping more be cannot say for sure card.

The purpose of this utility model is on the basis of horizontal gyrating type vice, designs a kind of jaw angle can also be done left-right rotation and front and back rotation in three-dimensional certain limit toolmaker's vise.

Toolmaker's vise of the present utility model is on the basis of existing swinging vice, caliper is connected with plane between the rotating disk changes sphere into and connect, making on the basis that jaw can rotate on the plane can also left-right rotation and the toolmaker's vise that rotates of front and back, its structure comprises the caliper that fixed caliper and moving caliper are formed, steering wheel and base, it is characterized in that the caliper bottom is a hemisphere, the top of steering wheel is concave spherical surface, and also comprise the locking pull bar, tie down screw and locking nut, have a fan groove on the hemisphere of described caliper bottom under shed, have the arc T-slot of a upward opening on the concave spherical surface on steering wheel top, the upper end of locking pull bar has a conical bore, the lower end is inverted T-shaped, tie down screw is connected with locking nut, be contained in respectively on the hemisphere of fan groove both sides, the locking pull bar is contained in the fan groove, the conical bore of its upper end is enclosed within on the taper seat of locking nut, the hemisphere of caliper bottom is installed on the concave spherical surface on steering wheel top, and the lower end of locking pull bar is stretched out fan groove and is inlaid in the arc T-slot of concave spherical surface.

Accompanying drawing 1 is the structural representation of the utility model toolmaker's vise;

Accompanying drawing 2 is right views of accompanying drawing 1.

Referring to accompanying drawing, 1 among the figure is moving caliper, the 2nd, and fixed caliper, the 3rd, steering wheel, the 4th, base, the 5th, bolt, the 6th, nut, the 7th, locking pull bar, the 8th, Plane Angle chi, the 9th, return supports, and the 10th, tie down screw, the 11st, locking nut, the 12nd, anti-rotation nail, the 13rd, hemisphere, the 14th, the arc T-slot on the concave spherical surface, the 15th, front and rear angles chi, the 16th, left and right sides bevel protractor.This toolmaker's vise comprises the caliper of being made up of fixed caliper 2 and moving caliper 1, steering wheel 3, base 4, locking pull bar 7, tie down screw 10 and locking nut 11, the bottom of fixed caliper 2 is a hemisphere 13, the top of steering wheel 3 is concave spherical surface, on hemisphere 13, have a fan groove under shed, have the arc T-slot 14 of a upward opening on the concave spherical surface on steering wheel top, the upper end of locking pull bar 7 has a conical bore, the lower end is inverted T-shaped, tie down screw 10 is connected with locking nut 11, be contained in respectively in the locking hole on the hemisphere 13 of fan groove both sides, anti-rotation nail 12 is contained on the locking nut 11, locking pull bar 7 is contained in the fan groove, the conical bore of its upper end is enclosed within on the taper seat of locking nut 11, the hemisphere 13 of caliper bottom is installed on the concave spherical surface on steering wheel 3 tops, and the lower end of locking pull bar 7 is stretched out fan groove and is inlaid in the arc T-slot 14 of concave spherical surface.During use, the bolt 5 that unclamps between steering wheel and the base can be made jaw 360 degree rotations on horizontal plane; Rotation lock screw rod 10 outwards moves locking nut 11, the locking pull bar then moves down inverted T-shaped lower end and arc T-slot is unclamped, jaw can be made left-right rotation or do the front and back rotation along fan groove along the arc T-slot with hemisphere, the angle of Zhuan Donging can reach 46 degree to the left or to the right, the angle of Zhuan Donging can reach 45 degree forward, the angle that rotates backward can reach 47 degree, make vice can in three-dimensional certain limit, adjust the jaw angle arbitrarily, satisfied the needs of clamping processing special workpiece, return supports 9 can make jaw get back to horizontal level fast.When jaw position need can support 9 with return and take away when rotate the front lower place.After mixing up angle, rotation lock screw rod 10 moves inward locking nut 11, and the locking pull bar then moves up the inverted T-shaped lower end is locked hemisphere and concave spherical surface in the arc T-slot.For the ease of grasping the angle of rotating, the front and rear angles chi 15 that rotates before and after can on hemispheroidal front-back, being carved with, on the steering wheel surface of front and rear angles chi both sides, be carved with the left and right sides bevel protractor 16 of left-right rotation, add the existing Plane Angle chi 8 that horizontally rotates on the steering wheel, just can grasp jaw position in the concrete angle of three dimensions, use more convenient.

Toolmaker's vise of the present utility model makes vice can adjust the jaw angle arbitrarily in three-dimensional certain limit.Satisfy the needs of clamping processing special workpiece, realized that a clamping can process at any angle to workpiece, both can make universal machine vice, can make the universal turret vice again, had simple and reasonable, high efficiency and advantage such as extremely easy to use.
