Description

Shaft positioning tool

Technical Field

The utility model relates to a location frock belongs to press technical field.

Background

The press (including a punch press and a hydraulic press) is a universal press with an exquisite structure. The press machine has the characteristics of wide application, high production efficiency and the like, and can be widely applied to processes of cutting, punching, blanking, bending, riveting, forming and the like. The metal is processed into parts by applying a strong pressure to the metal blank to cause plastic deformation and fracture of the metal. When the mechanical press works, a motor drives a large belt pulley (usually used as a flywheel) through a triangle belt, and a crank-slider mechanism is driven through a gear pair and a clutch, so that a slider and a male die move down linearly. After the forging and pressing work of the mechanical press is finished, the sliding block moves upwards, the clutch is automatically disengaged, and meanwhile, the automatic device on the crankshaft is switched on, so that the sliding block stops near a top dead center. However, in the prior art, a transmission shaft key groove processed by the press is positioned by using a V-shaped block, a special clamp is not provided, only one piece can be clamped at a time, parts are frequently assembled and disassembled and calibrated, the auxiliary time is long, and the production efficiency is seriously influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an axle piece location frock through reasonable in design anchor clamps, adopts many clamping methods, reduces the assistance-time, improves production efficiency.

In order to realize the above-mentioned purpose, the utility model provides an axle piece location frock, including fixing the bottom plate on the lathe workstation, the bottom plate is fixed with a plurality of V-arrangement locating pieces, V-arrangement locating piece upside parallel is equipped with the V-arrangement groove that the upper shed of several rows was used for horizontal fixed axle piece, the top in V-arrangement groove is equipped with the clamp plate that is used for the solid axle piece of pressure.

Compared with the prior art, the utility model has the advantages that the shaft to be processed is placed in the V-shaped groove on the V-shaped positioning block, and then the pressing plate is adjusted to press the shaft downwards, so that the shaft can be firmly fixed in the V-shaped groove, and a plurality of shaft workpieces can be fixed and clamped at one time for mechanical processing; through reasonable in design anchor clamps, adopt many clamping methods, reduce the assistance-time, improve production efficiency, the utility model discloses can be used to the quick clamping of axle piece dress.

As a further improvement, the bottom plate passes through locating pin and packing ring fixed connection with the V-arrangement locating piece, can make the V-arrangement locating piece can fix a position the installation on the bottom plate fast through locating pin and packing ring like this, has reduced the time of calibration greatly.

As the utility model discloses a further improvement, the clamp plate is just having seted up the arc wall in the one side in V-arrangement groove, can compress tightly the axle through the arc wall better when the clamp plate pushes down the axle like this, avoids the axle skew to appear, influences the machining precision.

As a further improvement of the utility model, the clamp plate is through bolt and V-arrangement locating piece fastening connection, can adjust the distance between clamp plate and the V-arrangement locating piece like this well to adapt to the size of treating the processing axle piece very conveniently.

As a further improvement, the bottom plate is fixed on the machine tool workbench through the T-shaped groove bolt, so that the connection between the bottom plate and the machine tool workbench is firmer.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a view from the direction a-a in fig. 1.

The device comprises a base plate, a pressure plate, a positioning pin, a gasket, an axle piece and an arc-shaped groove, wherein the pressure plate comprises a T-shaped groove bolt 1, a bottom plate 2, a bolt 3, a pressure plate 4, a V-shaped positioning block 5, a positioning pin 6, a gasket 7, an axle piece 8 and an arc-shaped groove.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

a shaft member 8 positioning tool shown in fig. 1-2 comprises a bottom plate 2 fixed on a machine tool workbench, wherein a plurality of V-shaped positioning blocks 5 are fixed on the bottom plate 2, a plurality of rows of V-shaped grooves which are opened upwards and used for transversely fixing the shaft member 8 are arranged on the upper sides of the V-shaped positioning blocks 5 in parallel, and a pressing plate 4 used for pressing and fixing the shaft member 8 is arranged above the V-shaped grooves; the bottom plate 2 is fixedly connected with the V-shaped positioning block 5 through a positioning pin 6 and a gasket 7; an arc-shaped groove 9 is formed in one surface, opposite to the V-shaped groove, of the pressing plate 4; the pressing plate 4 is fixedly connected with the V-shaped positioning block 5 through a bolt 3; the bottom plate 2 is fixed on a machine tool workbench through a T-shaped groove bolt 1.

In the utility model, the bottom plate 2 is fixed on the machine tool workbench through the T-shaped groove bolt 1, the pressing plate 4 is connected on the V-shaped positioning block 5 by the bolt 3, the V-shaped positioning block 5 is fixed on the bottom plate 2, the bottom plate 2 is connected with the V-shaped positioning block 5 through the positioning pin 6 and the gasket 7, the fixture formed by the V-shaped positioning block 5 and the pressing plate 4 can be quickly positioned, only the cleanness of the surface of the machine tool workbench, the fixture mounting surface and the workpiece positioning surface needs to be noticed in the processing process, the calibration time is greatly reduced, the shaft 8 to be processed is placed in the V-shaped groove on the V-shaped positioning block 5, and then the pressing plate 4 is adjusted to press the shaft 8 downwards, so that the shaft 8 can be firmly fixed in the V-shaped groove, a plurality of shaft type workpieces can be fixed and clamped at one; through designing reasonable anchor clamps, adopt many clamping methods, reduce the assistance-time, improve production efficiency.
