Abstract

The present invention relates to a kind of central flat tongs. It is characterized by that it has a threaded shaft. Said threaded shaft cam be used for providing motive force for moving jaw, the jaw and tongs body are precision-ground, and the power of said threaded shaft can be provided by human hand or electric device.

Description

The center flat-nose pliers

In the technical field machining in order to the device of clamping work pieces.

The existing flat-nose pliers of background technology all has a regular jaw, and moving jaw moves clamping work pieces at leading screw effect lower edge vice body to regular jaw.Shortcoming is that actuating speed is unhappy, can only can only accomplish the location of a guiding by power manually is provided, and is short of the flexibility (adaptability) of operation of wide scope, is short of multi-faceted clamping.

Summary of the invention this case provides one to drive fast, takes into account man power and electric power, a plurality of directions location, the anchor clamps scheme with wide range accommodation of multi-faceted clamping.At first, this case adopts diameter, pitch, spiral shell identical deeply, and screw thread moves towards opposite leading screw (as among Fig. 15, among Fig. 25,6, among Fig. 34, among Fig. 47,8) provide clamping power for moving jaw, leading screw can be same thick stick (as among Fig. 1 5), also can be two thick sticks (as among Fig. 25,6).With the positive and negative silk of thick stick screw thread and the supporting moving jaw lower end that acts on of moving jaw with positive and negative silk nut.The axle thick stick of two thick sticks by being arranged in flat-nose pliers bottom is (as Fig. 27, among Fig. 32, among Fig. 4 9) the synchronous effect masterpiece that provides is used for two positive and negative leading screws, the transmission of its power as shown in Figure 3, wherein 1 is rotating reductor electric power gear, its transmission of power is given axle thick stick 2, pass to again and transmit gear 3, pass to feed screw nut position limited gear 5 again, pass to leading screw 4 again, and obtain synchronously but the opposite common moment of jaw moving direction at pincers ends opposite side leading screw, under man power or electrodynamic turning effort, rotate to be two moving jaws with the supporting positive and negative silk leading screw of nut the power that relatively moves is provided.Secondly, this case takes into account man power and electric power, Fig. 1 is a man power, Fig. 2 is an electric power, man power can directly impose on moving jaw upper end or lower end (as among Fig. 34 or Fig. 3 in 2), electric power offers moving jaw by a rotating reducing motor (as among Fig. 21, among Fig. 4 10) by gear (as among Fig. 3 1).At last, add two independent spacing leading screws in the flat-nose pliers left and right sides location of both direction and clamping force (in as Fig. 44,5) are provided, 4,5 are location clamping moving jaw among Fig. 4, moving jaw can be fixed on the vice body by screw, thereby form cross center flat-nose pliers, its power equally both can be that man power can be an electric power also, was that positive and negative leading screw is different with the position of both sides independence leading screw, and the limiting mode difference of leading screw.Compare with existing flat-nose pliers, the center flat-nose pliers has quick clamping action, its operating efficiency is higher, it is quick to reduce more convenient operation with electronic power-actuated labour intensity, cross center flat-nose pliers then has concurrently and clamps and positioning action, realize the location and the clamping of a plurality of frees degree, thereby security reliability improves.

Description of drawings Fig. 1 worker center flat-nose pliers of behaving, wherein 1 is vice body, and 2,3 is moving jaw, and 4 is the spacing supporting disk of leading screw, and 5 is positive and negative silk leading screw.Fig. 2 is an electric power center flat-nose pliers, and wherein 1 is the rotating reductor, and 2 is vice body, and 3,4 is moving jaw, and 5,6 is positive and negative silk leading screw, and 7 are synchronous effect mechanical axis thick stick, and 8,9 are the pincers end.Fig. 3 is the flat-nose pliers pincers end combination of electric power center, and wherein 1 is the rotating reducer gear, and 2 are synchronous effect mechanical axis thick stick, and 3 for transmitting gear, and 4 is leading screw, and 5 is the feed screw nut position limited gear, and 6 are the pincers end.Fig. 4 is a cross center flat-nose pliers, and wherein 1 is vice body, and 2,3 is moving jaw, and 4,5 is the independent spacing moving jaw, and 6 is retaining screw, and 7,8 is positive and negative silk leading screw, and 9 are synchronous effect mechanical axis thick stick, and 10 are the rotating reductor.

Specific embodiment center flat-nose pliers can be man power (as Fig. 1) and electric power (as Fig. 2), also can be both comprehensive (as Fig. 4), man power center flat-nose pliers vice body is made with the high-carbon steel grinding, moving jaw slides along vice body and clamps and unload power, positive silk leading screw and forward leading nut are combination, anti-silk leading screw and anti-silk nut are combination, provide in opposite directions to come clamping work pieces and unload workpiece with the opposite power that moves for moving jaw under synchronous effect power.Electric power center flat-nose pliers provides power by the rotating reductor, by gear, synchronous effect mechanical axis thick stick, power is passed to positive and negative silk leading screw, moves with leading screw control moving jaw.Cross center flat-nose pliers is comprehensive flat-nose pliers, and promptly based on a center flat-nose pliers, the additional moving jaw that two independent leading screws are arranged in the left and right sides is from a plurality of frees degree location and clamping work pieces.Vice body, moving jaw, the spacing supporting gear of feed screw nut, positive and negative silk leading screw requires to have quite high precision, requires different precision according to its demand is different with purposes.The high-carbon steel that normally will not quench processing back quenching is ground to the each several part part and is combined into the center flat-nose pliers.

Claims

1, center flat-nose pliers and existing flat-nose pliers all are to provide clamping power by leading screw, move holding workpiece by jaw along vice body, it is characterized in that by two or four corresponding translations of moving jaw, provide artificial clamping power by a secondary positive and negative leading screw or many paranema thick stick, or provide electric power by a rotating reductor, and spacing at the flat-nose pliers end surface supporting, a positive screw pair is identical with anti-silk feed screw nut auxiliary air gap, guarantees that the flat-nose pliers center is accurately with fixing.

2, described two corresponding translations of moving jaw provide power by a secondary positive and negative leading screw according to claim 1, it is characterized in that leading screw has a central point or relative central point, and leading screw one end be that positive silk is combination with forward leading nut, and an end be that anti-silk is to make up with anti-silk nut.

3, according to described four the corresponding translations of moving jaw of claim 1, provide power by a secondary positive and negative leading screw or many paranema thick stick, it is characterized in that vice body is a cross, guiding is by the positive and negative leading screw control moving jaw clamping work pieces that relatively moves, and both sides provide artificial clamping power by two independent spacing leading screws.
