Abstract
The utility model discloses general flat tongs and bench vice for a machine tool. The general flat tongs and bench vice for the machine tool comprise a chuck, and sawteeth are arranged on the chuck on the side opposite a to-be-clamped workpiece. By means of the general flat tongs and the general bench vice for the machine tool, the torque generated when the workpiece is clamped by a fixture and is jacked upwards is eliminated by the chuck, the force of friction between the workpiece and the fixture is increased, therefore, machining of the workpiece can meet the requirements of the size and geometrical shape regulated by a drawing, and machining accuracy is improved greatly.
Description
Technical field
The utility model relates to a kind of jig, the lathe in particularly a kind of universal fixturing flat-nose pliers and bench vice.
Background technology
In machining, anchor clamps are to guarantee that workpiece to be machined obtains correct position on lathe, and work in-process prevents because the position that cutting force causes changes and a kind of important technological equipment of workpiece deformation.Use jig, help guaranteeing the machining accuracy of workpiece, the quality of stable prod; Help improving labor productivity and reduce cost; Help improving workman's working condition, guarantee safety in production; Help enlarger bed process scope, realize " a tractor serves several purposes ".
The existing jig of Shi Yonging, when clamping work pieces, move the maximum clamping force (do not produce the situation of mechanically deform under) of chuck to the generation of workpiece, the reaction force of this clamping force and chuck fastening material, the application point of two power is not point-blank, clamping force produces a torsion that makes progress to the workpiece that is clamped, this torsion can cause institute's clamping work pieces loosening easily, and workpiece is moved up and influences machining accuracy.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of general flat-nose pliers of lathe, bench vice that can improve machining accuracy to be provided.
Technical scheme: in order to realize above purpose, the general flat-nose pliers of a kind of lathe described in the utility model, bench vice comprise: chuck; The side that described chuck is relative with workpiece to be clamped is provided with downward-sloping sawtooth; The utility model has increased the chuck of a downward-sloping sawtooth, and sawtooth flexible downward sawtooth in clamping process can balance out and easily cause the loosening torsion upwards of workpiece, and it is mobile that workpiece is not produced, and improved the machining accuracy of workpiece.
The front end of sawtooth described in the utility model is vertical plane, and vertical plane has effectively protected workpiece not damaged by anchor clamps.
Chuck described in the utility model adopts the polyurethane of shore hardness 75 degree, and this chuck is a flexible material, stressed buffering when making workpiece clamped, and it is impaired that workpiece is difficult for.
Beneficial effect: the general flat-nose pliers of a kind of lathe described in the utility model, bench vice compared with prior art have the following advantages:
The workpiece torque that jack-up produces that makes progress had increased the frictional force of anchor clamps between workpiece when 1, chuck had been eliminated clamp in the utility model, made the processing of workpiece can better reach size, the geometry of drawing regulation, had improved the precision of processing greatly;
2, the utility model has effectively reduced the processing cost of anchor clamps.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is user mode figure of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
Embodiment
As the general flat-nose pliers of the described a kind of lathe of Fig. 1, Fig. 2, bench vice, comprise chuck 1, fixture 2, moving member 3; Described fixture 2 is fixed on the lathe 4, and described moving member 3 is fixed in the track on the lathe 4, and described chuck 1 is fixed on the moving member 3; Described chuck 1 and workpiece to be clamped 5 relative sides are provided with the sawtooth 11 described sawtooth 11 of projection; Described sawtooth 11 is downward-sloping oblique sawtooth for front end, and this oblique sawtooth is vertical plane foremost.
Claims (3)
1. the general flat-nose pliers of lathe, bench vice is characterized in that: comprising: chuck (1); The side that described chuck (1) is relative with workpiece to be clamped is provided with downward-sloping sawtooth (11).
2. the general flat-nose pliers of a kind of lathe according to claim 1, bench vice is characterized in that: described sawtooth (11) front end is vertical plane.
3. the general flat-nose pliers of a kind of lathe according to claim 1, bench vice is characterized in that: described chuck adopts the polyurethane of shore hardness 75 degree.
