Detailed Description

The following description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.

Example (b): as shown in attached figure 1 and attached figure 2, a structure of special handling instrument of encoder, including screwdriver handle 11, still including setting gradually on 11 terminal surfaces of screwdriver handle and through with encoder main shaft spiro union mode in order to be used for outwards taking out threaded rod 1 of encoder main shaft sets up stiffener 2 on 1 terminal surface of threaded rod, and set up on 2 terminal surfaces of stiffener and be used for outwards ejecting during 1 spiro union of threaded rod encoder main shaft just avoids the screwdriver pole 3 in encoder main shaft spiro union hole and motor main shaft spiro union groove, the diameter of stiffener 2 and screwdriver pole 3 all is less than threaded rod 1.

In this embodiment, threaded rod 1 with the encoder main shaft spiro union is to outwards ejecting the encoder main shaft, makes remove taper friction fit relation between encoder main shaft and the motor main shaft, and screwdriver pole 3 is the encoder main shaft is by outside ejecting supporting part, and requires screwdriver pole 3 to avoid last spiro union hole of encoder main shaft avoids last spiro union groove of motor main shaft, consequently screwdriver pole 3 adopts the design of less diameter.

On the other hand, the reinforcing rod 2 is used for avoiding the problem that the structural strength is low between the threaded rod 1 and the screwdriver rod 3 due to the fact that the diameter difference is large, and the effects of strengthening the structure and prolonging the service life are achieved.

Be equipped with encoder main shaft screw on the threaded rod 1, encoder main shaft screw follows threaded rod 1 is close to the one end position department of stiffener 2 begins to set up. The diameter of the reinforcing rod 2 is larger than that of the screwdriver rod 3. The encoder main shaft thread is an M14 thread. The diameter of stiffener 2 is 6mm, the diameter of screwdriver pole 3 is 4 mm.

In this embodiment, encoder main shaft screw thread is used for the spiro union with the spiro union hole spiro union of encoder main shaft to be used for ejecting outward after the main shaft screw takes off encoder main shaft, 4mm screwdriver pole 3 can effectively avoid screw thread on encoder main shaft spiro union hole and the motor main shaft spiro union groove avoids the broken ring screw thread.

The screwdriver handle 11 is provided with a groove, and an annular protection plate is arranged on one side, close to the threaded rod 1, of the screwdriver handle 11.

In this embodiment, the screwdriver handle 11 and the annular protection plate are made of existing rubber, and play a role in holding and protecting.

An inner hexagonal plate means 4 for opening a rear cover of the encoder and dismounting an inner hexagonal screw of the encoder is arranged at a position, far away from one end of the reinforcing rod 2, on the screwdriver rod 3, and the specification of the inner hexagonal plate means 4 is 4 mm.

In this embodiment, the socket head cap wrench 4 is a regular hexagonal prism, the outer contour of which does not touch the peripheral threads, and the socket head cap screw of the encoder is the spindle screw.

And a second inner hexagonal plate means 5 for dismounting a screw of the tensioning ring is arranged at one end of the screwdriver handle 11, which is different from the end where the threaded rod 1 is arranged, and the specification of the second inner hexagonal plate means 5 is 2 mm.

In this embodiment, the second inner hexagonal plate means 5 is also a regular hexagonal prism and is used for removing the tension ring screw.

So far, the use method and advantages of the special handling tool for the encoder can be summarized as follows:

firstly, the rear cover is detached and the inner hexagon screw of M5, namely the spindle screw, is detached by the inner hexagon plate means 4 and the second inner hexagon plate means 5;

secondly, the tensioning ring screw is taken down by the second inner hexagonal plate means 5;

thirdly, the screwdriver rod 3 is inserted into the encoder spindle screwing hole and abuts against the inner side face of the motor spindle screwing groove, the encoder spindle is rotated on the threaded rod 1, the encoder spindle is separated from the motor spindle, and the encoder spindle is ejected out, so that preliminary disassembly operation is completed;

fourthly, the encoder main shaft is rotationally taken down from the threaded rod 1, and then all disassembly operations are completed;

fifthly, when the encoder is installed, the main shaft of the encoder is inserted firstly, the hexagon socket head cap screws are screwed, then the tensioning ring screws are installed again, and finally the rear cover is covered, so that the multi-step operation can be completed by using only one tool, and the convenience of the assembling and disassembling operation is ensured.

The screwdriver handle 11, the threaded rod 1, the reinforcing rod 2, the screwdriver rod 3 and the middle shafts of the inner hexagonal plate means 4 are all located on the same straight line.

In this embodiment, the screwdriver handle 11, the threaded rod 1, the reinforcing rod 2, the screwdriver rod 3, and the inner hexagonal plate means 4 all need to be inserted into the spindle hole of the encoder to rotate, and therefore a coaxial structure is required, and the second inner hexagonal plate means 5 is used for reversely using and assembling and disassembling the tension ring screw, so that the second inner hexagonal plate means 5, the screwdriver handle 11, and the threaded rod 1 may be coaxial or not.

The second inner hexagonal plate means 5 is arranged on the end surface of the threaded rod 1 different from the end surface of the reinforcing rod 2, and the screwdriver handle 11 is arranged on the outer annular surface of the threaded rod 1.

In this embodiment, the screwdriver handle 11 is cast on the outer circumferential surface of the threaded rod 1 for gripping and applying force.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the appended claims.
