Description

Adjustable V-shaped frame for machining shaft key grooves

Technical Field

The utility model relates to the field of machinary, specifically a strutting arrangement during processing of axle type part.

Background

When the shaft key groove is machined conventionally, the shaft bracket needs to be leveled and clamped on the V-shaped iron. When the X-axis (relative to a machine tool) is leveled, the two V-shaped irons are required to be adjusted to the same horizontal height; when the shaft has no same shaft diameter at two ends in the Y-axis direction (relative to a machine tool), the leveling is very difficult, the height of a part is adjusted by using a gasket, the ideal positioning precision cannot be achieved, the position degree of the key groove relative to the shaft is out of tolerance, and a lot of working time needs to be consumed in the adjusting process.

Disclosure of Invention

In order to solve the technical problem, the utility model aims to provide an adjustable V-shaped frame for processing shaft keyways, a plurality of adjustable V-shaped frames are arranged below a shaft to be processed, each adjustable V-shaped frame comprises V-shaped iron, and the V-shaped iron is fixed with the axial end face of a screw rod; the lower end of the V-shaped iron is provided with a groove, the screw rod is embedded into the groove, and a first positioning key is arranged between the screw rod and the groove; the lower part of the screw rod is inserted into the mounting hole of the base, and a second positioning key is arranged between the lower part of the screw rod and the mounting hole; the outer side of the screw rod is rotationally connected with the adjusting nut; the lower part of the adjusting nut is abutted with the upper end of the base; the base lower extreme sets up the locating convex block, the T type inslot of locating convex block embedding workstation.

And a pit is arranged at the upper end of the V-shaped iron, and a screw penetrates through the through hole of the pit and then is screwed with the top end of the screw rod.

A plurality of blind holes are radially formed in the nut, and the rotating lever is inserted into the blind holes.

The lower end of the base is provided with a positioning groove, and the positioning lug is embedded into the positioning groove and fixed on the lower part of the base through a screw.

The utility model has the advantages that: after the V-shaped iron support shaft is adjustable, the shaft position of any end can be continuously and steplessly adjusted through the rotation of the nut; the operation is convenient, a crane is not needed, the workload of machine tool operators and crane workers is reduced, and the use of the machine tool and the crane is simplified.

Drawings

FIG. 1 is a schematic view of the present invention;

fig. 2 is a left side view of fig. 1.

Detailed Description

The utility model is described in detail with reference to the accompanying drawings, as shown in the drawings, a plurality of adjustable V-shaped frames are arranged below the processing shaft 10, the specific number can be determined according to the length of the processed shaft, and 2-4 adjustable V-shaped frames can be selected; the number of the present embodiment is 2. The adjustable V-shaped frame comprises V-shaped iron 1, and the V-shaped iron 1 is fixed with the axial end face of the screw rod 3; the lower end of the V-shaped iron 1 is provided with a groove 13, and the upper end of the screw rod 3 is embedded into the groove 13; in order to prevent the screw rod and the V-shaped iron 1 from rotating relatively, a first positioning key 2 is arranged between the screw rod 3 and the groove; the lower part of the screw rod 3 is inserted into a mounting hole 14 of the base 5, and the mounting hole 14 is a blind hole and has a certain depth, so that the axial movement stroke of the screw rod 3 is met; in order to prevent the screw rod from rotating relative to the mounting hole, a second positioning key 6 is arranged between the lower part of the screw rod 3 and the mounting hole; the outer side of the screw is rotationally connected with an adjusting nut 4; the lower part of the adjusting nut 4 is abutted with the upper end of the base 5; the base lower extreme sets up locating convex block 7, locating convex block 7 embedding workstation 8 in the T type groove 9.

The upper end of the V-shaped iron is provided with a pit 12, and a screw passes through a through hole of the pit and then is screwed with the top end of the screw rod 3.

In order to facilitate turning the nut, the latter is provided with a plurality of blind holes in the radial direction, into which the rotary levers 11 are inserted.

The lower extreme of base sets up positioning groove, and locating convex block 7 imbeds in the positioning groove through the fix with screw in the lower part of base.

The utility model fully utilizes the T-shaped groove of the workbench, and ensures the Z-direction unification of each adjustable V-shaped frame; the plurality of adjustable V-shaped frames distributed along the X direction can continuously and steplessly adjust the Y-direction position of any end by rotating the nut; furthermore, the utility model discloses a structure convenient operation need not use the crane, has reduced machine tool operator and crane worker's work load, has simplified the use of lathe and crane.
