Furthermore, a T-shaped groove is formed in the upper surface of the machine tool, a T-shaped block matched with the T-shaped groove and a stud arranged on the T-shaped block are arranged in the T-shaped groove, a groove for the stud to penetrate through is formed in a bottom plate of the support body, a nut is connected to the stud, and the support body and the T-shaped block are fixed through the nut.

Furthermore, the groove is positioned on the edge of the bottom plate of the supporting body.

Furthermore, a base plate is arranged above the bottom plate, and the stud penetrates through the base plate and then is in threaded connection with the nut.

Furthermore, a long hole is formed in the base plate, and the stud penetrates through the long hole.

Furthermore, a positioning key convenient for realizing positioning with a machine tool is arranged on the lower surface of the supporting body.

Furthermore, the number of the support bodies is two, and the center distance of the threaded holes in two adjacent support bodies is equal to the center distance of the two counter bores in the part.

The utility model discloses an actively the effect does: the utility model discloses utilize the supporter to fix the part, the supporter is located the below of part, when carrying out the part milling, can not form with the cutter and interfere, the cutter need not to dodge, and one-time forming does not exist and connects the tool mark, need not to carry out a lot of clamping, has avoided repeated positioning error to improve machining efficiency, promoted workpiece quality.

Detailed Description

The utility model discloses mainly be applicable to the processing operation that mills of a mount, there is counter bore 4 as the pilot hole on this kind of mount, the utility model discloses utilize counter bore 4 to fix it with lathe 1. Besides, the method is also applicable to milling machining operations of other parts with assembly holes.

As shown in fig. 1-4, the present invention includes a support body 2 fixed on a machine tool 1 and a threaded hole 13 provided on the upper surface of the support body 2 for corresponding to a counter bore 4 on a part 3.

The upper surface of the machine tool 1 is provided with a plurality of T-shaped grooves 11, T-shaped blocks 5 matched with the T-shaped grooves 11 and studs 6 arranged on the T-shaped blocks 5 are arranged in the T-shaped grooves 11, the support body 2 is I-shaped, grooves 10 for enabling the studs 6 to penetrate through are formed in a bottom plate 9 of the support body 2, a base plate 7 is arranged above the bottom plate 9, and the base plate 7, the bottom plate 9 and the T-shaped blocks 5 are fixed through the studs 6 and bolts 8 fixed on the T-shaped blocks 5, so that the support body 2 is fixed on the machine tool 1.

The recess 10 is located on the edge of the bottom plate 9 of the support body 2 so that the stud 6 passes through the recess 10.

The shim plate 7 is provided with a long hole 12, the stud 6 penetrates through the long hole 12, and the long hole 12 can reduce the machining precision requirement of the shim plate 7.

And a positioning key convenient for realizing positioning with the machine tool 1 is arranged on the lower surface of the supporting body 2.

The number of the support bodies 2 is two, and the center distance of the threaded holes 13 on two adjacent support bodies 2 is equal to the center distance of the two counter bores 4 on the part 3. The left end and the right end of a bottom plate 9 of the support body 2 are respectively provided with a groove 10, a base plate 7, a T-shaped block 5 and a stud 6, and the support body 2 is fixed at the two ends.

The utility model discloses when using, pack into lathe 1's T type groove 11 earlier with T type piece 5 in, put lathe 1's bed surface with supporter 2 again, guarantee recess and T type groove 11 on the supporter 2 to it, guarantee simultaneously that the screw hole 13 centre-to-centre spacing on two supporters 2 is unanimous with the pilot hole centre-to-centre spacing on the part 3, put supporter 2 with part 3 on, guarantee that screw hole 13 on the supporter 2 aligns with the pilot hole pair of part, then utilize the bolt to insert from the pilot hole of part 3 (counter bore 4 promptly), screw in is to screw hole 13 in, realize compressing tightly fixedly of part 3 and supporter 2, use backing plate 7 and bolt 8 at last to fix supporter 2 and prepare processing on lathe 1's the surface of a wound.
