Abstract
The utility model relates to a bi-directional gad tong with a trapezoid lead screw and pertains to a machining tool used for replacing an old gad tong (commonly known as a vise). The utility model essentially consists of essential parts of a rotating lead screw, trapezoid nuts, a clamp body, a movable clamp body and a clamp block, etc., wherein, the rotating lead screw is a bi-directional trapezoid lead screw, one end of which rotates left and the other end thereof rotates right; trapezoid nuts are designed as a left trapezoid nut and a right trapezoid nut; the bi-directional trapezoid lead screw connects the left trapezoid nut and the right trapezoid nut together by screwing. The utility model is able to double the running speed of the gad tong and meanwhile has the advantages of small friction and time and labor-saving application by using a screw pair.
Description
Technical field
The utility model relates to a kind of machine tools.
Background technology
Traditional flat-nose pliers (being commonly called as vice) adopts common unidirectional leading screw, and during work, leading screw rotates with the screw that is fixed on the vice body and forms screw, and the step of leading screw one end drives moving caliper and forms mobilely, clamps or unclamps.Because except that the frictional force of leading screw helicoid, leading screw step end face and moving caliper end face also produce frictional force during work, therefore, the translational speed of old-fashioned flat-nose pliers is slow, consumption power is big.
Summary of the invention
Task of the present utility model provide a kind of rapidly and efficiently, time saving and energy saving, do not increase simultaneously the two-way trapezoidal screw flat-nose pliers of manufacturing cost again.
Two-way trapezoidal screw flat-nose pliers adopts compound screw mechanism, is made up of main parts size such as rotational lead screw, trapezoidal nut, vice body, moving caliper, pincers seats.Trapezoidal nut is designed to left and right two, and left trapezoidal nut is fixed on the vice body, and right trapezoidal nut is installed on the moving caliper, and moving caliper is installed in pressing plate and bridge screw on the guide rail of vice body, and the jaw connector also is equipped with in the left side of moving caliper.Rotational lead screw is a two-way trapezoidal screw, and it links into an integrated entity left and right trapezoidal nut by spiral, constitutes compound screw mechanism.During work, rotational lead screw rotation, the hand of spiral of left and right trapezoidal nut is opposite, and the equal and opposite in direction of helical pitch, and therefore, the displacement of moving caliper is the twice of the displacement of rotational lead screw, and promptly leading screw whenever turns around, moving caliper two pitch of advancing.
In sum, adopt two-way trapezoidal screw, the movement velocity of flat-nose pliers is doubled, reached purpose rapidly and efficiently.In addition, the utility model has been cancelled the step end face of leading screw, adopts screw pair, and frictional force is little, and is time saving and energy saving during use.

The specific embodiment
As shown in Figure 1, 2, the utility model mainly is made up of pincers seat 1, vice body 2, moving caliper 5, trapezoidal nut 6,7 and two-way trapezoidal screw 8.Vice body 2 is fixed on the pincers seat 1 by attachment screw 9 and attaching nut 12.Left side trapezoidal nut 6 (its structure is seen Fig. 4, Fig. 5) is fixed on the vice body 2, and right trapezoidal nut 7 (structure is seen Fig. 6, Fig. 7) is installed on the moving caliper 5.It is jaw 3 and jaw screw 4 that the jaw connector is housed in the left side of moving caliper 5, and the bottom of moving caliper 5 cooperates with the guide rail of vice body 2 by pressing plate 11 and bridge screw 10, to guarantee the reciprocating motion of moving caliper 5 along vice body 2.
The structure of two-way trapezoidal screw 8 as shown in Figure 3, its end is designed to left-handed leading screw A, the other end is designed to dextrorotation leading screw B, and the left-handed leading screw A of two-way trapezoidal screw 8 and dextrorotation leading screw B are connected by spiral with left trapezoidal nut 6 and right trapezoidal nut 7 respectively, form compound screw mechanism.Right-hand member head at two-way trapezoidal screw 8 is equipped with handle.During work, turning handle, two-way trapezoidal screw 8 rotations, leading screw 8 forms screw with the left trapezoidal nut 6 that is fixed on the vice body 2, makes moving caliper 5 with right trapezoidal nut 7 fixed thereon and leading screw 8 motions, the pitch of advancing; And right trapezoidal nut 7 that is fixed together with moving caliper 5 and the screw that leading screw 8 forms also make moving caliper 5 pitch of advancing.Therefore, two-way trapezoidal screw 8 turns around, moving caliper 5 two pitch of advancing.Thereby reach the purpose of quickness and high efficiency.Because the utility model has been cancelled the step end face of original leading screw, only adopts screw pair, not only frictional force is little, and has all avoided the dead point of moment when clamping or unclamping, and not only saves time but also laborsaving during use.
