Summary of the invention
The purpose of this utility model provides a kind of accuracy height, lightness part processing milling fixture easy and simple to handle.
The technical solution of the utility model is, lightness part processing milling fixture, comprise chuck body with front/rear end, the front end face of described chuck body has the clamping locating surface with the corresponding close fit of locating surface of part, and the upper and lower that is interval in the position location of described part on the described chuck body front end face is provided with the clamping device that part can be pressed on the described clamping locating surface; Be equipped with the alignment pin group that is made of a plurality of alignment pins or locating piece on the described clamping locating surface between upper and lower clamping device, described alignment pin group comprises the following alignment pin that cooperates with the bottom face of part location or locating piece and locate side alignment pin or the side locating piece that cooperates with the side that part moves into the inboard of milling fixture down at least.
The rear end face of described chuck body is provided with the groove of stepping down that the part protruded for part enters.
Following alignment pin horizontal distribution in the described alignment pin group point-blank.
The both sides, bottom of described chuck body have and are used for the mounting groove that links to each other with platen.
Described clamping device is upper and lower pressing plate clamping device, described every cover pressing plate hold down gag includes and is convexly equipped with the installation pad post that is fixed on the chuck body front end face, screw, the pressing plate of movable set on screw by screwed hole spinning corresponding on the chuck body, it is roughly the same that described installation pad post end stretches out the thickness of the length of chuck body and part, and when screw screws with the spacing cooperation of corresponding end face of lower platen.
Milling fixture of the present utility model, upper and lower two clamping device actings in conjunction by the locating surface upper and lower are in part, make the part stress equilibrium, clamping location difficulty when having solved the lightness part processing, poor rigidity, machining deformation are big, and precision be cannot say for sure the problem demonstrate,proved, guaranteed the part processing quality, improved production efficiency, clamp structure is simple, and is easy and simple to handle, can be made into seriation, have application value more widely.
In addition, the rear end face of chuck body of the present utility model is provided with the groove of stepping down that the part protruded for part enters, protuberance on the part can not interfered with anchor clamps and influence the location, on the other hand owing to be provided with on the chuck body and allow bit architecture, also make the corresponding matching compactness of other parts of part and anchor clamps, the location contact is tightr.
Description of drawings
Structural representation when Fig. 1 is a clamping parts of the present utility model;
Fig. 2 removes left view behind the part for Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, milling fixture of the present utility model comprises chuck body 1, the front/rear end of chuck body 1 is a right-angled trapezium, the both sides, bottom of chuck body 1 have mounting groove 9, the front end face of chuck body 1 is the locating surface of part 7, can with the clamping locating surface close fit at part 7 back sides, the rear end face of chuck body 1 is provided with the groove 8 of stepping down that the part 7-1 that protrudes for part 7 back sides enters, the disappearance part of the groove 8 of stepping down can play the loss of weight effect simultaneously.
Chuck body 1 front end face is provided with the two covers symmetrically arranged upper and lower pressing plate clamping device in interval up and down, the lower platen hold down gag comprise be convexly equipped with the installation pad post 2 that is fixed on chuck body 1 front end face, by screw 5, the lower platen 3 of movable set on screw 5 of screwed hole spinning corresponding on the chuck body 1, between tail cap and lower platen 3, also be set with packing ring 4 on the screw 5.It is roughly the same that described installation pad post 2 ends stretch out the thickness of the length of chuck body 1 and part 7, and when screw screws with the spacing cooperation of corresponding end face of lower platen 3.The top board hold down gag comprises top board 3 ', and its structure is identical with the structure of above-mentioned lower platen hold down gag, leaves the space that enters for part between the upper and lower pressing plate clamping device.
Chuck body 1 front end face is fixed with the alignment pin group that is made of three alignment pin 6-1,6-2,6-3 by blind hole between upper and lower pressing plate clamping device, three alignment pin distribution modes are for down on two one, below two following alignment pin 6-1,6-2 horizontal distribution point-blank and with the bottom face location of part 7 cooperates, above side alignment pin 6-3 be biased in a side and locate with the side of the inboard of part 7 immigration milling fixtures and cooperate.
