Description

A milling shaft end groove fixture

technical field

The utility model relates to the field of machinery, in particular to a clamp.

Background technique

Vertical milling machine is a powerful metal cutting milling machine, the equipment has strong rigidity, large feed variable range, and can withstand heavy-duty chips. The spindle of the vertical milling machine is arranged vertically, and the worktable can be lifted up and down. The milling cutter used in the vertical milling machine is relatively flexible and has a wide range of applications. It can be used for milling keyways, milling planes, etc. Boring, etc. The vertical milling machine is easy to use, mainly because the hanger can be used to enhance the tools, mainly three-sided edge milling cutters and sheet milling cutters. At the same time, the vertical milling machine has a wide processing range and is suitable for processing various parts. Holes, etc., the milling head can be vertically milled at 90° and can be rotated and adjusted by ±45°. However, when the existing vertical milling machine is motorized along the three directions of X, Y, and Z, the main shaft adopts passive braking, and the brake rotates. The torque is small, the stopping speed is slow, the use safety is low, and the operation reliability is poor. In the production process, some small parts are often required to be processed, and the existing milling machine cannot be fixed, which is inconvenient to process.

SUMMARY OF THE INVENTION

In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a milling shaft end groove fixture, which includes a base, a fixed end plate is arranged on the base, two sliding plates are arranged on the fixed end plate, and two through holes of the V-shaped block are provided. Put on the sliding plate; V-shaped grooves are arranged on the inner sides corresponding to the two V-shaped blocks, the radial direction of the workpiece is clamped between the two V-shaped grooves, the bottom of the workpiece is overlapped on the top block, and the top block is rotated. Tighten in the screw hole on the base; an eccentric wheel is arranged on the outer side of the V-shaped block away from the fixed end plate, the rotating shaft of the eccentric wheel is not set at the center of the eccentric wheel, and the rotating shaft is fixed on the base; the eccentric wheel A handle is arranged on the upper; the radial outer side of the eccentric wheel is in contact with the outer side of the V-shaped block away from the fixed end plate.

In order to prevent the V-shaped block from falling off the end of the sliding plate, the end plate of the sliding plate close to the eccentric wheel is provided with a protrusion.

In order to adapt to workpieces of different diameters, the outer side of the sliding plate between the fixed end plate and the V-shaped block is sleeved with a backing ring.

The base is fixed on the machine table by bolts.

The utility model has the advantages of reasonable structure, accurate positioning and convenient installation, and is suitable for milling shaft end grooves.
