Problems solved by technology

Not only the number of shutdowns is more, but the local wear of the machine tool track is relatively serious, and it is not convenient to use, and the production efficiency is also greatly restricted
On the other hand, its fixed jaw seat is under one-way force, which is easy to break, and its service life is short, and it cannot be used as a centering vise

Embodiment 1

[0018] Embodiment one: the present invention is used as the embodiment of double-jaw flat-nose pliers.

[0019] Such as figure 1 As shown, this embodiment includes a base 1, a clamp body 4 fixed on the base 1 by bolts, and a detachable fixed jaw seat 7 is installed on the clamp body 4. The detachable fixed jaw seat 7 is installed and positioned on the body of the pliers 4 through bolts and two tapered pins.

[0020] An X-axis circular through hole is opened on the clamp body 4, and a lead screw 3 is installed in the circular through hole. Two left and right movable jaw seats are arranged on the left and right sides of the clamp body 4, that is, the left movable jaw seat 9 and the right movable jaw seat 5, and the two movable jaw seats are respectively connected with the left and right nuts that are sleeved on the lead screw 3. 10 are closely fitted and connected, and the two sections of screw threads that the leading screw 3 matches with the left and right nuts 10 move in t...

Embodiment 2

[0025] Embodiment 2: The present invention is used as the embodiment of the flat-nose pliers for the centering machine.

[0026] Such as figure 2 As shown, in this embodiment, the detachable fixed jaw seat 7 is removed on the basis of the first embodiment, and the following screw axial positioning mechanism is added.

[0027] Such as image 3 , the described screw axial positioning mechanism is as follows:

[0028] A circular through hole is opened on the clamp body 4 at the front and rear, and the axes of the two circular through holes coincide and perpendicularly intersect with the axis of the lead screw 3 . A centering plunger 12 is respectively arranged in each through hole. The inner end of the centering plunger 12 is provided with a conical hole, and a centering steel ball 13 is installed in the conical hole. Groove 6 matches. An adjusting screw rod 14 is fixedly installed on the outer end of the centering plunger 12 .

[0029] A fixed nut 15 is installed at the ou...

Abstract

The invention relates to a pair of bidirectional flat-nose pliers for a machine. When the bidirectional flat-nose pliers serve as a pair of double-jaw flat-nose pliers for a machine, the bidirectional flat-nose pliers can clamp two workpieces one time instead of one, the number of shutdown times is reduced, production efficiency is improved by more than one time, and the method is suitable for an occasion with a low requirement for centering of the workpieces; when the bidirectional flat-nose pliers serve as a pair of centering flat-nose pliers for a machine, axial displacement of a lead screw is precisely limited under the abutting effect of a front centering steel ball and a rear centering steel ball and the force applied by the two centering steel balls of two locking mechanisms jointly, and therefore precise centering of the workpieces is achieved. In this way, the bidirectional flat-nose pliers can achieve dual purposes.

Description

[0001] technical field [0002] The invention relates to a flat-nose pliers used on machine tools, in particular to a two-way flat-nose pliers for machines. Background technique [0003] Traditional machine vises, also known as machine vises, have only one jaw and can only hold one workpiece at a time. Not only the number of shutdowns is more, but the local wear of the machine tool track is relatively serious, and the use is not convenient enough, and the production efficiency is also greatly restricted. On the other hand, its fixed jaw seat bears unidirectional force, which is easy to break, has a short service life, and cannot be used as a centering vise. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a two-way machine vise, which can be used not only as a double-jaw machine vise but also as a centering machine vise, so as to overcome the shortcomings of the above-mentioned existing products. [0005] In...
