Description

Closed encoder assembly and disassembly tools

Technical Field

The utility model relates to the technical field of encoder disassembling and assembling devices, in particular to a closed encoder disassembling and assembling tool.

Background

Closed encoders (e.g., Siemens 6FX2001 series encoders) are widely used in digital controlled equipment, and typically have speed feedback and position feedback functions. The encoder is classified according to the installation mode, and comprises an internal encoder and an external encoder, wherein the internal encoder is usually installed at the tail part of the motor and protected by a motor shell, so that the external environment pollution is not easily caused; the external encoder is usually mounted on a machine tool main body, such as a screw end portion, a spindle transmission portion, a rack transmission portion and the like, and is easily polluted by dust, oil stains, cooling water, scrap iron and the like. The numerical control equipment has more faults caused by an externally installed encoder, wherein the faults of the numerical control equipment are common due to the fact that the encoder is polluted. For the maintenance of the closed encoder, a maintenance worker usually uses a conventional disassembling tool to disassemble the encoder for maintenance. However, the conventional disassembling tool has the phenomena of difficult disassembly and easy damage to the encoder during the disassembly process, thereby not only prolonging the maintenance time and increasing the maintenance cost, but also greatly reducing the service life of the closed encoder.

the fixed seat is used for being detachably connected with the body;

the clamp assembly is used for clamping the shell;

the connecting piece is used for driving the fixed seat and the clamp component to approach each other so as to connect the shell and the body together; the connecting piece is also used for driving the fixed seat and the clamp assembly to be away from each other so as to separate the shell from the body.

Further, the connector comprises a plurality of bolts;

the fixed seat is provided with a plurality of first connecting holes matched with the bolts, and the clamp assembly is provided with a plurality of second connecting holes matched with the bolts;

when each bolt sequentially passes through the second connecting hole and the first connecting hole and is forced to move from the second connecting hole to the first connecting hole, the connecting piece drives the fixed seat and the clamp assembly to mutually approach, so that the shell and the body are connected together;

when each bolt penetrates through the first connecting hole to be connected with the side wall of the clamp assembly and is forced to move from the first connecting hole to the clamp assembly, the connecting piece drives the fixed seat and the clamp assembly to be away from each other, so that the shell is separated from the body.

Furthermore, a plurality of third connecting holes are formed in the middle of the fixing seat, and the fixing seat is in threaded connection with the body through the third connecting holes.

Further, the fixing seat is a circular ring-shaped sheet body.

Furthermore, a circular groove is formed in the middle of the fixing seat and used for containing one end of the body.

Further, the circular groove is coaxial with the fixing seat.

Further, the clamp assembly includes a first clamping piece and a second clamping piece, the first clamping piece and the second clamping piece being configured to be in threaded connection.

The closed encoder body and the shell can be easily disassembled or assembled by driving the fixing seat and the clamp component to be close to or far away from each other through the connecting piece. Specifically, when the connecting piece drives the fixing seat and the clamp assembly to approach each other, the shell and the body are connected together, that is, the shell and the body are installed; when the connecting piece drives the fixed seat and the clamp component to be away from each other, the shell is separated from the body, namely the shell and the body are detached.
