Abstract

The utility model provides a hand vice which is a gold processing tool. The utility model is composed of a right and a left vice arms, a screw rod 1, a butterfly nut 2, a screw rod seat 11, a resetting spring 14 and a hollow shaft 16. The hand vice has the advantages of reasonable structure design, convenient manufacture and safe and reliable operation. The hand vice is an indispensable ideal tool in the gold processing industry, the electrical and mechanical maintenance industry and a family.

Description

Hand vice

At present, in aircraft, automobile, tractor and various flight-line maintenance industry and metalworking industry, also do not see can make things convenient for, the hand tools of firm grip small workpiece, parts or thin type plate.The existing thing instrument of holding, as bench vice, combination pliers, hand vice (be commonly called as hand and take son), more or less all exist such or such defective.Bench vice, volume is big, and heaviness is difficult to clamping than small workpiece, the unfavorable family that enters; Combination pliers, though commonly used, also can the clamping widget, can't eliminate lasting fatigue, effort, hold the not firm shortcoming of thing; Also there is lasting effort in hand vice, and fixedly use is made with curved nail because of the screw rod in the clamp mechanism is many and stuck, tong arm usually to be occurred and to cause jack panel and can't keep plane parallel to contact, and cause easy to wearly, and consumable accessory is many, service life shortcoming such as weak point.Above several thing instruments of holding also all exist a common defective to be exactly, and are difficult to firm grip cylindricality workpiece, so affect the machining accuracy to the cylindricality workpiece.

The purpose of this utility model is held thing instrument--hand vice for solving the custom-designed a kind of ideal that is used for metalworking, dynamo-electric maintenance and family's use of the existing many defectives of above instrument exactly.

The technical solution of the utility model is achieved in that at first does a pair of tong arm, and afterbody is hinged together two tong arms with the parts of bolt, axle or other two tong arms that can be hinged.Two tong arm antedorsals leave the stop platform, and preceding inboard processes the object plane of holding--the jaw with constant slope.Jaw and tong arm one, having overcome common anchor clamps is that mobile easily causes and holds the shortcoming that thing is not firm, influence machining accuracy because of jaw.On the jaw,, process a V-type and hold the post groove therein, so that clamping cylindricality workpiece along the tong arm direction.All being drilled with on two tong arms can be for the hole of putting the tight mechanism of clamping.Then, make a screw rod, pass a wherein tong arm, an end of screw rod by being hinged or being fixed on another tong arm, is promoted closing up of two tong arms at the other end of screw rod with nut, the jaw place is formed close state, reach the purpose of holding workpiece.For solving the fixing purpose of using hand vice, on its easily fixing tong arm, put and adorn a fixed mount.Like this, just made the hand vice that to do.

Below in conjunction with drawings and Examples the technical solution of the utility model is done following detailed description;

At first use tool steel (or general iron and steel or hot investment casting) to make left and right as shown in drawings tong arm 4,8, afterbody, the front portion of tong arm are drilled with the hole, stop platform 10 is left in the front portion of tong arm, preceding inboard at left and right tong arm 4,8, go out to have the left and right jaw 5,6 of constant slope through annular knurl or grinding or additive method processing and fabricating, the shape that jaw is held object plane can be made into washboard shape or net is buckled shape or fish scale shape, right jaw 6 centers on right clamp arm 8 have V-type along the tong arm direction and hold post groove 7, and the inboard device of its tong arm has sheet or round return spring 14.Then, making a hollow shaft 16 that has a certain taper is hinged together left and right tong arm 4,8 at afterbody.Produce the screw rod 1 shown in the accompanying drawing again, screw bolt seat 11, wing nut 2, screw rod 1 pass left clamp arm 4 and are hinged together by pin 9 and the screw bolt seat 11 that is positioned in right clamp arm 8 holes movingly.For the fixing hand vice that uses, make a fixed mount 12 and be sleeved on the screw bolt seat 11.

Hand vice is under off working state, and left and right tong arm 4,8 is that left and right jaw 5,6 separates under the effect of return spring 14, is in the state of dehiscing.During work, workpiece is placed between two jaws, the wing nut 2 that turns clockwise, compressing left clamp arm 4 closes up to right clamp arm 8, causes the closure of left and right jaw 5,6, clamping work pieces.When unloading workpiece, be rotated counterclockwise wing nut 2, two tong arms and separate under the effect of return spring 14, left and right jaw was opened, is dehisced in 5,6 minutes.

This hand vice, the left and right jaw 5,6 in inclined-plane, having guaranteed has bigger clamping force in the jaw forward position, and folder power in outer is greater than inside, is the advantage that clips with the clamping small workpiece, and V-type is held post groove 7 and is provided convenience for folder cylindricality workpiece again.Hollow shaft 16 has certain taper, has guaranteed that left and right tong arm 4,8 relative hollow shafts 16 have one to be movable, have one to fix.Screw rod 1 is hinged with the pin 9 of screw bolt seat 11, has guaranteed all to make under free position wing nut 2 to contact with the plane parallel of left clamp arm 4, has promptly guaranteed reliable clamping, has guaranteed that again each parts is not easy to wear.Stop platform 10 is convenient to make location, stop usefulness when the work of hand-held hand vice, and then fixed mount 12, again for the fixing hand vice that uses provides convenience, as long as on the fixed mount 12 on workbench, base station, just reach the fixedly purpose of hand vice.And, guaranteed hand vice changing location arbitrarily again, with carry out multi-faceted file, grind, mill, processing such as brill.When clamping work pieces, fixed mount 12 relative right clamp arms 8 are fixed, and under the off working state, then are rotating relatively.

Because this hand vice is safe in utilization, reliable, reasonable in design, cheap, easy to use, thus be metalworking, the indispensable small tool that dynamo-electric maintenance industry and family are comparatively desirable.

Claims
