[0023] The mounting seat structure of the rotary table encoder disclosed by the utility model mainly applies to the mounting seat structure design of traditional rotary table encoders, which is relatively simple, and the movable structure inside the mounting seat is fixed in installation mode. When the internal rotating shaft needs to be lubricated, some fixed structures need to be disassembled, lubricating liquid is difficult to supplement, and the overall process is complicated.

[0024] Referring to Figure 1 and Figure 3 A mounting seat structure of a rotary table encoder, comprising a bottom plate 1 and two bases 2 arranged on the top outer wall of the bottom plate 1, a first mounting cylinder 5 and a second mounting cylinder 6 are arranged on the top outer wall of each base 2, further comprising: a lubricating mechanism, the lubricating mechanism comprises a second rotating shaft 10 arranged in the first mounting cylinder 5 and a first rotating shaft 9 arranged in the second mounting cylinder 6, two first mounting frames 15 and two mounting plates 17 are symmetrically arranged on the circumferential inner wall of the first mounting cylinder 5, a spray bottle 16 is arranged on the top outer wall of each first mounting frame 15, two electric telescopic rods are arranged on the bottom outer wall of each mounting plate 17, a pressing plate 3 is connected to the piston end of each electric telescopic rod, and the two pressing plates 3 are used in cooperation with the two spray bottles 16; a sensing mechanism, the sensing mechanism is arranged on the first rotating shaft 9.

[0025] Among them, the second rotating shaft 10 is connected with the inner wall of the first mounting cylinder 5 through a bearing, and the two spray bottles 16 are used in cooperation with the bearing.

[0026] For example, the traditional rotary table encoder generally needs to be disassembled to add lubricating oil, and the position of the bearing is found to add the lubricating product, so that frequent disassembly of the machine is not only very troublesome, but also affects the service life of the machine. The present application can reduce the damage to the parts of the equipment.

[0027] Specifically, in the scheme, by setting two spray bottles 16 and two pressing plates 3 on the first mounting cylinder 5 opposite the bearing connection, the lubricating oil and other lubricating products in the spray bottle 16 can be saved, and the pressing plate 3 is controlled to press down to spray the lubricating oil and other lubricating products in the spray bottle 16 to the bearing connection, thereby lubricating the bearing connection regularly, preventing the parts from rusting and affecting the rotation of the turntable. The steps are simple, the operation is convenient, and the process of disassembling the mounting seat when using lubricating oil in the past is avoided.

[0028] Among them, the third shell is arranged on one side of the outer wall of the first mounting cylinder 5, and the circular holes are arranged on one side of the outer wall of the two first mounting frames 15. The movable doors 4 are arranged on the outer walls of the two circular holes.

[0029] Specifically, by arranging the circular holes on the two first mounting frames 15, and simultaneously penetrating the spray bottle 16 connected with the two first mounting frames 15, and cooperating with the two movable doors 4, when the lubricating oil and other lubricating products in the spray bottle 16 are exhausted, the third shell and the two movable doors 4 are opened, and the lubricating oil and other lubricating products are poured into the spray bottle 16, thereby prolonging the lubricating effect.

[0030] Referring to Figure 1 and Figure 5 In a preferred embodiment, the encoder body 7 is connected to the opposite side outer wall of the first rotating shaft 9 and the second rotating shaft 10, and the first shell 8 is arranged on the top outer wall of the encoder body 7.

[0031] Among them, the second shell is arranged on one side of the outer wall of the first mounting cylinder 5, and the circular holes are arranged on one side of the outer wall of the first shell 8 and the second shell.

[0032] Specifically, by arranging the circular holes on the first shell 8 and the second shell, the rotation angle can be measured by the photoelectric sensor. When the rotating part of the encoder rotates, the code disc rotates, the circular hole meets the photoelectric sensor, and the subsequent signal conversion is completed.

[0033] Referring to Figure 1 and Figure 4 In a preferred embodiment, the second mounting frame is arranged in the first mounting cylinder 5, the motor 14 is arranged on the top outer wall of the second mounting frame, and the output shaft of the motor 14 is connected to the first rotating shaft 9.

[0034] Specifically, by arranging the motor 14 in the second mounting cylinder 6, power can be provided to rotate the first rotating shaft 9, drive the encoder body 7 to rotate together with the second rotating shaft 10, and complete the encoding work.

[0035] Referring to Figure 2 and Figure 3In a preferred embodiment, the sensing mechanism comprises a mounting block arranged on the outer wall of the first rotating shaft 9, the mounting block is provided with a sensor 11 on one side of the outer wall, and warning lights 12 are arranged on the circumferential outer wall of the mounting block at equal distances, and a standard disc 13 is arranged on one side of the second rotating shaft 10, and the standard disc 13 is used in cooperation with the sensor 11.

[0036] For example, the rotary table encoder is a precision device with high accuracy requirements, and the coaxiality of the two rotary tables needs to be ensured, otherwise errors will occur during the operation of the device, resulting in incorrect signals and affecting the subsequent signal output. The sensing mechanism can avoid such situations.

[0037] In the specific use process, the sensor 11 and the warning lights 12 arranged on the first rotating shaft 9 cooperate with the standard disc 13 with multiple tracks arranged on the second rotating shaft 10, the inner center of the standard disc 13 corresponds to the position of the sensor 11, and the revolution of the rotary table encoder can be detected. When the infrared ray of the sensor 11 deviates from a certain track on the standard disc 13 (the specific number of tracks can be adjusted according to the situation), the warning lights 12 start to light up to provide a warning, which can avoid the generation of incorrect signals.

[0038] Working principle: when in use, the sensor 11 and the warning lights 12 arranged on the first rotating shaft 9 cooperate with the standard disc 13 with multiple tracks arranged on the second rotating shaft 10 to detect the revolution of the rotary table encoder. When the infrared ray of the sensor 11 deviates from a certain track on the standard disc 13, the warning lights 12 start to light up to provide a warning. Then, the third shell is opened, and the two movable doors 4 are opened. Through the circular holes arranged on the two first mounting frames 15 and the spray bottles 16, lubricating oil and other lubricating products are poured into the interior of the spray bottles 16. Through the two spray bottles 16 and the two pressure plates 3 arranged on the first mounting cylinder 5 opposite to the bearing connection, the pressure plates 3 can be controlled to be pressed down to spray the lubricating oil and other lubricating products in the spray bottles 16 to the bearing connection for lubricating the bearing connection regularly to avoid the coaxiality deviation.

The substitution can be the substitution of part of the structure, device, method step, or the complete technical solution. According to the technical solution and the inventive concept of the present application, equivalent substitution or change should be covered within the protection scope of the present application.
