Description

Miniature cross roller guide rail linear motor platform

Technical Field

The utility model belongs to the technical field of electromechanical device and specifically relates to a miniature cross roller guide rail linear electric motor platform is related to.

Background

The linear motor is a rotary servo motor which is unfolded simply by unfolding a closed magnetic field into an open magnetic field and directly converting electric energy into mechanical energy for linear motion without any transmission device of an intermediate conversion mechanism. A rotary induction motor is conceived to be cut open in a radial direction and to expand the circumferences of a stator and a rotor into a straight line, which results in the simplest iron-cored linear induction motor.

For the application with large span, the single-shaft or cantilever application cannot be satisfied, only a double-drive structure is used, and double drive is synchronized through grating ruler feedback and a double-drive algorithm. In the field of the existing linear motors, the linear motor platform is relatively large in size, the size is difficult to be small based on the sizes of a movable stator and a universal linear guide rail, and the universal linear guide rail has a creeping phenomenon during low-speed operation, so that the speed uniformity is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem of insufficient grinding in the prior art.

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

a micro cross roller guide rail linear motor platform comprises a base and two guide rails which are arranged on the base in parallel from left to right, wherein the guide rails are cross roller guide rails;

the linear motor stator is arranged between the two guide rails of the base, and the linear motor rotor is arranged at the corresponding position below the sliding seat.

The base is fixedly provided with a grating ruler, and the grating ruler is laterally attached to the inner side surface of the base and is arranged in parallel with the guide rail.

The motor platform is provided with an encoder for control, the encoder is arranged on the lower side of the sliding seat, and the encoder and the grating ruler are arranged oppositely.

And sliding seat side baffles are respectively arranged at two end parts of the crossed roller guide rail and are arranged at the front side and the rear side of the sliding seat.

The grating ruler and the encoder keep a 0.8mm gap.

The utility model discloses this device can be great save space, and the structure is extremely compact, and the speed homogeneity under the low-speed condition is guaranteed to the cross roller guide rail. The cross rollers are much smoother than the conventional linear guide.

The utility model discloses form by several simple part equipment, easy to assemble, easy to detach, easy operation. Still have light in weight advantage that dustproof effectual.
