Description

Main spindle box clamping type main motor plate fixing device

Technical Field

The utility model belongs to precision machine tool makes the processing field, concretely relates to headstock centre gripping formula owner motor plate fixing device.

Background

The main spindle box is an important part of a machine tool, is used for arranging a working spindle of the machine tool, transmission parts of the working spindle and a device of a corresponding additional mechanism, and mainly plays a role in supporting the spindle and enabling the spindle to rotate so as to realize the functions of starting, braking, speed changing, reversing and the like of the spindle. The main shaft is driven to move by the main shaft motor, and the main motor plate is used for fixing the main shaft motor, so that the stability of the main motor plate is ensured at first. The traditional main motor plate fixing method is to fix a main motor plate and a main spindle box through fixing parts such as screws, but the internal space of the main spindle box is too small, so that the electrode plate is difficult to fix or is not firmly fixed.

Disclosure of Invention

An object of the utility model is to avoid prior art not enough, provide a headstock centre gripping formula main motor plate fixing device to effectively solve prior art's problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

Further, the screw holes are formed in the edges of the pressure plate and the main motor plate 3; the press plates are in one-to-one correspondence with the screw holes in the main motor plate in the vertical direction.

Furthermore, the screw hole is provided with a plurality of, and the symmetry sets up respectively in the both sides of clamp plate and main motor board.

Furthermore, a matching plate is arranged at the top of the main spindle box body; a balancing telescopic rod is vertically arranged between the balancing plate and the top of the sliding seat; the balancing telescopic rods are arranged in parallel and are respectively arranged at the tops of the two side edges of the sliding seat.

Further, a groove is formed in the inner edge of the main motor plate; the inner edge of the pressing plate is provided with a convex block; the groove is matched and embedded with the lug.

Further, a circular ring fixing ring is fixedly arranged on the outer wall of the main shaft; the width of the circular ring fixing ring is the same as that of the groove and the lug.

Compared with the prior art, the utility model discloses following beneficial effect has at least:

the utility model discloses an install the clamp plate structure additional in the headstock, through fastening screw, be in the same place clamp plate and main motor board are fixed, in the installation, fastening screw can follow the clamp plate bottom and install, has avoided traditional passing through fixed parts such as screws with main motor board and headstock fixed, causes the plate electrode to be difficult to fix, or fixed insecure problem. In addition, through set up the ring retainer plate on the main shaft, set up recess and lug on clamp plate and main motor board, further promoted fixed strength. The utility model discloses the installation is simple, and intensity is high, is fit for extensively using widely.
