Specific embodiment
Refer to Fig. 1-Fig. 3, the utility model is a kind of fixture for machine-building, and it includes fixture 1 and bolt
4；Fixture 1 includes fixed block 11, gripping block 12 and cushion block 13.
Fixed block 11 is provided through the installing hole 111 of fixed block 11；The bottom of fixed block 11 is provided with locating piece 112；
The side wall of fixed block 11 is provided through the installation screwed hole 113 of fixed block 11.
Gripping block 12 is provided through the hole 121 of gripping block 12；Gripping block 12 is provided through the clamping of gripping block 12
Screwed hole 122.
Fixed block 11 and gripping block 12 are by through hole 121 and screw in and install the bolt 4 of screwed hole 113 and be fixedly connected.
Cushion block 13 is arranged between fixed block 11 and gripping block 12；Bolt 4 screws in clamping screwed hole 122 and supports cushion block
13.
The lower surface (plane that i.e. fixed block 11 is contacted with machine table 21) of fixed block 11 and the upper surface of locating piece 112
(plane that i.e. locating piece 112 is contacted with processing workpiece 3) isoplanar.
Fixed block 11, gripping block 12 and cushion block 13 can be 40 No. five steel and make.Can ensure that intensity, machinery adds
Man-hour fixture 1 deflection is less, thereby may be ensured that machining accuracy.
Packing ring can also be cased with bolt 4.Can prevent in mechanical processing process, bolt 4 loosens and affects machining accuracy.
The operation principle that one of the utility model is used for the fixture of machine-building is: during use, fixed block 11 is led to
Cross bolt 4 (being arranged on the bolt 4 of machine table 21) and nut 5 is fixedly installed in the machine table 21 of milling machine 2；Then will pass through
Hole 121 simultaneously unclamps screwing in the bolt 4 installing screwed hole 113, puts into processing workpiece 3 between fixed block 11 and cushion block 13,
And make the bottom surface of processing workpiece 3 concordant with the upper surface of locating piece 112；Then by bolt 4 (through the bolt 4 of hole 121)
Through hole 121 and screw in installation screwed hole 113 so that fixed block 11 is fixedly connected with gripping block 12；Swivel bolt 4 (screws in clamping
The bolt 4 of screwed hole 122) make bolt 4 (screwing in the bolt 4 of clamping screwed hole 122) support processing workpiece 3 by cushion block 13, make
Processing workpiece 3 is clamped to be fixed；Then start milling machine 2 and carry out machining.From the above, it is seen that in the utility model one
Kind for machine-building fixture, structure is simple, be easily installed；And lower surface (i.e. fixed block 11 and the processing of fixed block 11
The plane of platform 21 contact), upper surface (plane that i.e. locating piece 112 is contacted with the processing workpiece 3) isoplanar with locating piece 112,
So machining when, the bottom surface of processing workpiece 3 is exactly datum level it is ensured that machining accuracy.
In sum, one of the utility model is used for the fixture of machine-building, and structure is simple, be easily installed；And
The lower surface (plane that i.e. fixed block 11 is contacted with machine table 21) of fixed block 11, upper surface (the i.e. locating piece with locating piece 112
112 planes contacting with processing workpiece 3) isoplanar, during such machining, the bottom surface of processing workpiece 3 is exactly datum level, permissible
Ensure machining accuracy.
