Description
Technical Field
The invention relates to monitoring equipment, in particular to a rotating monitoring rotary table of a motor stator.
Background
The monitoring rotary table needs to meet the requirements of low equipment height and stable rotating operation in structural design, the motor serves as a power source device of the monitoring rotary table, performance selection and using methods have very important influences on the aspects of reducing the equipment height and improving the operation stability, and after the performance of the motor is determined according to the rotating parameter requirements of the monitoring rotary table, reasonable selection of the using method of the motor is directly related to the most reasonable design of the monitoring rotary table.
The motor can be divided into two major categories of inner rotor motor and outer rotor motor, and the structure all has two parts to constitute: the stator and the rotor are used in the conventional using method of the two types of motors, the stator is fixed, the rotor is driven in a rotating mode, and the power line of the motor is relatively fixed relative to the stator regardless of the inner rotor motor or the outer rotor motor.
The conventional use method of the motor on the monitoring turntable is to fix the stator on a static part of the monitoring turntable, and connect the rotor with a rotating part of the monitoring turntable to drive the observation device to rotate, as shown in fig. 1. The use method of fixing the motor stator and rotating the rotor can realize the basic function of the monitoring rotary table, but has three defects, and cannot realize the requirements of reducing the equipment height and improving the running stability of the monitoring rotary table to the maximum extent:
1. the rotating part of the monitoring rotary table is required to be arranged on the rotor connecting disc 1, a certain height exists on the mounting plane of the rotor connecting disc on the structure of the monitoring rotary table, and the overall height of the monitoring rotary table is overhigh due to the safety distance designed for avoiding the interference between the rotating part and the fixed part in the rotating process;
2. because the sectional areas of the motor rotor and the connecting shaft thereof are limited, for the monitoring rotary table with a larger sectional area of the upper rotating part, the supporting area of the rotating part is too small, and part processing errors can cause larger deviation of the outermost end of the rotating part in the rotating process, thus causing the instability of the whole structure to be increased and affecting the service life of the structure and equipment;
3. for the monitoring rotary table with the servo control and signal processing device positioned in the rotating part, because the motor stator is static, a power line on the stator can be connected with the servo control only through the conductive slip ring, and signal lines of various position and speed detection devices also need to be communicated with the signal processing device through the conductive slip ring, so that the number of loops of the conductive slip ring can be greatly increased, the length of the conductive slip ring is increased, and the overall height of the monitoring rotary table can be increased.
Disclosure of Invention
The invention aims to solve the technical problem of meeting the requirements of reducing the height of a monitoring turntable and improving the operation stability to the maximum extent, and provides the monitoring turntable with a rotating motor stator.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: a motor stator rotating monitoring rotary table comprises a base and a motor, wherein a motor rotor connecting shaft of the motor is fixedly connected with the base, and a motor rotor is matched with the motor rotor connecting shaft through a key groove and a fastening nut; a sub-connecting disc is arranged on the outer periphery of the motor stator, a monitoring rotary table is arranged on the stator connecting disc, and monitoring equipment is arranged on the monitoring rotary table.
And the inner ring of the stator connecting disc is matched with the motor stator through a matching spigot and a screw.
The monitoring rotary table is connected with the outer ring of the stator connecting disc through a positioning spigot, a guide key and a set screw.
The lower end of the motor rotor connecting shaft is connected with the flange plate through a key groove, and the flange plate is fixed on the base through a spigot and a set screw.
According to the monitoring turntable for the motor stator rotation, which is designed by adopting the technical scheme, the monitoring turntable is arranged on the stator connecting disc by adopting the scheme that the motor stator rotates and the rotor is fixed, so that firstly, the stress area and the stress diameter of a rotating part of the monitoring turntable are increased, the influence of machining shape and size errors of a driving part (comprising the motor and the stator connecting disc) on the rotating part is reduced, and the stability of the running process of the monitoring turntable is improved; secondly, the monitoring rotary table adopts the scheme of motor stator rotation and rotor fixation, and the rotating part is arranged on a motor stator connecting disc, so that the height of the rotating part can be greatly reduced compared with the height of the rotating part arranged on a motor rotor connecting disc; thirdly, for the monitoring turntable of the servo control and signal processing device in the rotating part, the scheme of motor stator rotation and rotor fixation is adopted, the power line, the position detection signal line and the speed detection signal line on the motor stator can rotate together with the rotating part, can keep relative static with the servo control and signal processing device, the power line and the signal line can communicate with the servo control and signal processing device without passing through a conductive ring, therefore, the number of the conductive slip ring channels can be reduced by more than ten rings, for example, a certain monitoring rotary table is taken, the number of the conductive slip ring channels required by a motor rotor rotation scheme is 41, the number of the conductive slip ring channels required by a motor stator rotation scheme is only 28, and the reduction of the number of the channels reduces the overall height of the monitoring rotary table, reduces the fault rate of line communication and improves the overall operation stability of equipment.

Fig. 1 is a schematic structural diagram of a conventional motor driving part with a rotating rotor and a fixed stator, and reference numeral 2 is a motor stator base, a conventional monitoring turntable provided with a monitoring device is arranged on a rotor connecting shaft, and because a rotor rotating shaft is thin and a rotor connecting disc is relatively high in position, the monitoring turntable bearing a certain device weight is limited in size and poor in stability in the operation and rotation process.
Referring to fig. 2 and 3, the monitoring turntable for motor stator rotation according to the present invention includes a base 9 and a motor, wherein the lower end of a motor rotor connecting shaft 3 of the motor is connected to a flange 7 through a key slot, the flange 7 is fixed to the base 9 through a spigot and a set screw, so that the motor rotor connecting shaft 3 is fixedly connected to the base 9, and a motor rotor 4 is matched with the motor rotor connecting shaft through a key slot and a set nut. A stator connecting disc 6 is arranged on the whole body of the motor stator 5, and the inner ring of the stator connecting disc 6 is matched with the motor stator 5 through a matching spigot and a screw. A monitoring rotary table 8 is arranged on the stator connecting disc 6, the diameter and the area of the monitoring rotary table 8 can be larger, and equipment for monitoring is arranged on the monitoring rotary table 8. For the monitoring turntable 8 without a rotating part, the monitoring turntable 8 is connected with the outer ring of the stator connecting disc 6 through a positioning spigot, a guide key and a set screw. For some monitoring turntables with a rotating part and a standing part, the rotating part of the monitoring turntable 8 is connected with the outer ring of the stator connecting disc 6 through a positioning spigot, a guide key and a set screw. Therefore, the rotary motion of the monitoring rotary table is finally realized through the scheme that the motor stator 5 rotates and the motor rotor 4 is fixed, so that the monitoring equipment realizes the rotation monitoring in different directions.
