Abstract

The utility model relates to a fixture of a milling machine, belonging to the technical field of metal processing. The technical scheme of the utility model is that: the fixture comprises an inversed 'T'-shaped base, a vertical lever, an eccentric wheel, a horizontal pull rod and an open washer, wherein the middle part of the vertical lever is rotatablely connected with a vertical plate of the base; and the lower end of the vertical lever is provided with a compression screw; the eccentric wheel is installed on a transverse plate of the base through a vertical pin shaft; the outer edge of the eccentric wheel is pressed on the compression screw of lower end of the vertical lever; and one end of the horizontal pull rod is hinged with the upper end of the vertical lever, and the other end of the horizontal pull rod sequentially penetrates through the vertical plate of the base and a main positioning hole of a workpiece and is provided with a clamping groove matched with the open washer. The fixture takes a hole processed on the workpiece as position basis and utilizes the self-locking performance of the eccentric wheel to clamp the workpiece. The fixture has the advantages of being simple to operate, high positioning precision, high positioning speed, good pressure consistency and the like. The fixture greatly improves the processing quality and working efficiency of the milling machine and is especially applicable to clamp workpieces with small volume and irregular shapes.

Description

A kind of fraise jig
Technical field
The utility model relate to a kind of can be little to volume, the out-of-shape workpiece is located fast, the fraise jig of clamping, belongs to the metalworking technology field.
Background technology
When using milling machine that workpiece is carried out Milling Process, should be earlier with the accurate clamping of workpiece on anchor clamps, clamping precision directly has influence on machining accuracy.Generally be to adopt method of scoring to determine the location of workpiece during traditional fraise jig clamping workpiece, utilize moving press plate then Work-sheet pressing.Little for volume, out-of-shape workpiece (workpiece for example shown in Figure 1), this anchor clamps are difficult to guarantee the positional precision of workpiece, have had a strong impact on the machining accuracy of milling machine, and complicated operation, clamping efficient is low.In addition, the moving press plate pressure of conventional brace is wayward, determines with operator's sensation fully, also exerts a certain influence to part processing precision.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of simple to operate, fraise jig that clamping precision is high is provided.
The alleged problem of the utility model realizes with following technical proposals:
A kind of fraise jig, comprise the base of falling the T-shape, vertical lever, eccentric wheel, girt and open washer in the formation, the middle part of described vertical lever and the riser of base are rotationally connected, its lower end is provided with housing screw, described eccentric wheel is installed on the transverse slat of base by vertical bearing pin, its outer rim roof pressure is on the housing screw of vertical lever lower end, one end of described girt is hinged with the upper end of vertical lever, and the other end passes the main locating hole of the riser of base and workpiece successively and is provided with the draw-in groove that is complementary with open washer.
Above-mentioned fraise jig, be provided with positioning tube between the riser of base and workpiece, described positioning tube is sleeved on the girt, and the one end is positioned at the main locating hole of workpiece, one end is positioned at the locating slot on the base riser, and positioning tube outer wall middle part is provided with the wing plate perpendicular to girt.
Above-mentioned fraise jig also comprises the assist location pin in the formation, described assist location pin is installed on the riser of base and is corresponding with the assist location hole of workpiece.
Above-mentioned fraise jig is provided with back-moving spring between the riser of housing screw and base.
The utility model as the location benchmark, and utilizes eccentric self-locking property clamping work pieces with finished hole on the workpiece, have simple to operate, advantage such as positioning accuracy height, speed are fast, and pressure consistency is good.Positioning tube is used to improve the versatility of these anchor clamps, changes different positioning tubes and can make this device adapt to different workpiece.The effect of assist location pin is to improve the workpiece positioning accuracy.Back-moving spring can make the clamping operation simpler.
The utility model has greatly improved the crudy and the operating efficiency of milling machine, is specially adapted to little, the in irregular shape workpiece of clamping volume.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of structural representation of workpiece;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a cutaway view of the present utility model;
Fig. 4 is that A is to view;
Fig. 5 is the clamping schematic diagram of workpiece.
Each label is among the figure: 1, base; 2, handle; 3, positioning key; 4, eccentric wheel; 5, vertical bearing pin; 6, vertical lever, 7, intermediate pin, 8, bearing pin; 9, girt; 10, housing screw; 11, hex nut; 12, positioning tube; 13, back-moving spring; 14, open washer; 15, assist location pin; 16, workpiece; 17, main locating hole; 18, assist location hole; 19, wing plate.
The specific embodiment
Referring to Fig. 2~Fig. 5, the utility model mainly is made up of base 1, vertical lever 6, eccentric wheel 4, girt 9, assist location pin 15 and open washer 14.Vertically lever 6 is hinged by intermediate pin 7 and base 1, and base 1 is fixed on the milling machine by positioning key 3, and a side of eccentric wheel 4 is provided with handle 2, and vertically lever 6 is hinged by bearing pin 8 and girt 9.
The utility model as the location benchmark, and adopts 2 points (positioning tube 12 and assist location pin 15) location with finished hole on the workpiece, finishes clamping according to the self-locking property of eccentric wheel 3 simultaneously.Turning handle 2 during clamping workpiece, and eccentric wheel 4 rotates, and housing screw 10 moves to the riser of base, and back-moving spring 13 is compressed, and vertically move to the direction away from the base riser upper end of lever 6, and girt 9 tension open washers 14 make workpiece compacted.After workpiece processed, backward rotation handle 2, eccentric wheel 4 also rotated thereupon, back-moving spring 13 elongations, housing screw 10 moves to the direction away from the base riser, and vertically lever 6 and girt 9 reset, unclamp open washer 14, so just realized quick location and dismounting.
