Abstract

The utility model discloses a machine tool fixture which comprises a cross beam and a longitudinal beam. The cross beam and the longitudinal beam are arranged on a machine tool body. An oblique beam is connected between the cross beam and a longitudinal beam, and the oblique beam can enable the cross beam to be adjusted up and down; a through hole is formed in the cross beam, a milling cutter is arranged in the through hole, a bolt is connected to the top of the milling cutter, a spring is arranged between the bolt and the cross beam, a pin shaft is arranged on the oblique beam, an adjusting-tool key is arranged on the contact face of the pin shaft and the oblique beam, the tail end of the pin shaft is of a threaded structure, and a nut is connected to the tail end in a sleeved mode. Through change of the fixture structure, the oblique beam and the cross beam are used for adjusting the position and fixing a workpiece in a multi-angle mode, and the purposes of improving machining flexibility and machining precision are achieved.

Description

A kind of jig

Technical field

The utility model relates to frock clamp field, is specifically related to a kind of jig.

Background technology

In the time that workpiece is carried out to lateral opening hole, due to the position of opening difference of different workpieces, therefore conventionally adopt the position that changes milling cutter to carry out perforate, cause so constantly adjusting jig, elongate the production cycle, simultaneously in process due to the change in location of milling cutter, cause workpiece easily to occur micro-rolling, penetration of a cutting tool position is not accurate enough, has affected machining accuracy, has caused the rising of fraction defective.

Utility model content

For solving the problems of the technologies described above, we have proposed a kind of jig, by changing clamp structure, utilize cant beam and crossbeam to adjust position, and workpiece multi-angle is fixed, and to reach lifting process flexibility, improve the object of machining accuracy.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of jig, comprises the crossbeam and the longeron that are arranged on fuselage, between described crossbeam and longeron, is connected with cant beam, can make described crossbeam carry out up-down adjustment by described cant beam; On described crossbeam, offer through hole, in described through hole, be provided with milling cutter, be connected with bolt at described milling cutter top, between described bolt and described crossbeam, pad is provided with spring, on described cant beam, be provided with bearing pin, tool setting key is housed on the contact-making surface of bearing pin and cant beam, and described pin the tip of the axis is helicitic texture, and is socketed with endways nut.

Further, on described cant beam, be also provided with positioning key.

By technique scheme, the utility model, by workpiece is positioned on cant beam, utilizes bearing pin to be coupling, its horizontal level is fixed, and the nut energy workpiece pressing on top, makes upright position firm, milling cutter vertical depression, owing to there being the effect of spring, therefore milling cutter is comparatively steady in the process pressing down, and after complete operation, steadily returns, the more important thing is, crossbeam can be adjusted up and down, thereby realize, the position of workpiece is adjusted, and has improved the flexibility ratio of processing.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the cutaway view schematic diagram of the disclosed a kind of jig of the utility model embodiment.

Numeral and the represented corresponding component title of letter in figure:

1. crossbeam; 2. bolt; 3. milling cutter; 4. spring; 5. nut 6. bearing pins; 7. workpiece; 8. positioning key; 9. tool setting key; 10. longeron; 11. cant beams.

The specific embodiment

Below in conjunction with embodiment and the specific embodiment, the utility model is described in further detail.

Embodiment

As shown in Figure 1, a kind of jig, comprises the crossbeam and the longeron that are arranged on fuselage, between described crossbeam and longeron, is connected with cant beam, can make described crossbeam carry out up-down adjustment by described cant beam; On described crossbeam, offer through hole, in described through hole, be provided with milling cutter, be connected with bolt at described milling cutter top, between described bolt and described crossbeam, pad is provided with spring, on described cant beam, be provided with bearing pin, tool setting key is housed on the contact-making surface of bearing pin and cant beam, and described pin the tip of the axis is helicitic texture, and is socketed with endways nut.

Workpiece is positioned on cant beam, is set on bearing pin, its horizontal level is fixed, the nut energy workpiece pressing on top, make upright position firm, milling cutter vertical depression, owing to there being the effect of spring, therefore milling cutter is comparatively steady in the process pressing down, after complete operation, steadily return, the more important thing is, crossbeam can be adjusted up and down, thereby realize, the position of workpiece is adjusted, improved the flexibility ratio of processing.

Further, on described cant beam, be also provided with positioning key, can, to being fixed on the diametric plane of workpiece, have further promoted the steadiness of workpiece in process, be conducive to promote machining accuracy.

Above-described is only the preferred embodiment of a kind of jig of the utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.

Claims

1. a jig, comprises the crossbeam and the longeron that are arranged on fuselage, it is characterized in that, between described crossbeam and longeron, is connected with cant beam, can make described crossbeam carry out up-down adjustment by described cant beam; On described crossbeam, offer through hole, in described through hole, be provided with milling cutter, be connected with bolt at described milling cutter top, between described bolt and described crossbeam, pad is provided with spring, on described cant beam, be provided with bearing pin, tool setting key is housed on the contact-making surface of bearing pin and cant beam, and described pin the tip of the axis is helicitic texture, and is socketed with endways nut.

2. a kind of jig according to claim 1, is characterized in that, is also provided with positioning key on described cant beam.
