Description

Technical Field

[0001] The present application relates to the field of encoder bodies, and in particular to a Hall rotary encoder. Background Art

[0002] The encoder body is a device that compiles and converts signals or data into signal forms that can be used for communication, transmission and storage. The encoder body converts angular displacement or linear displacement into electrical signals. The former is called a code disk and the latter is called a code ruler. According to the readout method, the encoder body can be divided into contact and non-contact types. According to the working principle, the encoder body can be divided into incremental and absolute types. The rotary encoder body is a photoelectric rotary measuring device that directly converts the measured angular displacement into a digital signal. The encoder body, if divided by the signal principle, has an incremental encoder body and an absolute encoder body. We usually use an incremental encoder body. The output pulse signal of the rotary encoder body can be directly input to the PLC, and the PLC's high-speed counter is used to count its pulse signal to obtain the measurement result. When using a conventional encoder body, the encoder body is installed behind the equipment. Several connectors are installed on the surface of the encoder body. The encoder body is connected to the equipment with the help of the connector to facilitate the control of the equipment.

[0003] With respect to the above-mentioned related technologies, the inventors believe that, when a conventional encoder body is installed, the encoder body is often installed inside the equipment by welding, which causes inconvenience during maintenance or replacement of a damaged encoder body because the welding position needs to be disassembled.

A fixing frame 5 is slidably connected to the surface of the slider 4. The bottom end of the fixing frame 5 is fixed to the inner wall of the equipment. The two ends of the encoder body 1 are limited by the connecting frame 3, so that the encoder body 1 is installed on the inner wall of the equipment, and the connecting frame 3 is convenient to move with the help of the slider 4 and the fixing frame 5. The two connecting frames 3 can be separated from the encoder body 1 to release the limit of the encoder body 1.

One end of the limit block 7 is fixedly installed on the surface of the encoder body 1. With the help of the limit block 7 and the card slot 6, the connecting frame 3 is conveniently fixed to the surface of the encoder body 1, which effectively improves the fixing effect of the connecting frame 3 on the encoder body 1, and the connecting frame 3 can be separated from the encoder body 1 by separating the limit block 7 from the card slot 6. A connecting block 8 is fixedly installed on one end of the fixing frame 5, and a connecting bolt 9 is clamped on the inner wall of the connecting block 8.

[0023] Reference Figure 3 - Figure 4 The adjusting frame 10 is slidably installed on the inner wall of the connecting frame 3. The inner wall of the adjusting frame 10 is rotatably connected to the limiting roller 12. The limiting roller 12 is controlled to move by means of the adjusting frame 10, and the bottom end of the limiting roller 12 pushes the top of the connecting head 2, so that the connecting head 2 is kept in contact with the inside of the device, avoiding the situation where the encoder body 1 is difficult to connect with the device due to the loosening of the connecting head 2. The top of the adjusting frame 10 is rotatably connected to the adjusting bolt 11, and the surface of the adjusting bolt 11 is threadedly installed with the inner wall of the connecting frame 3. The height of the adjusting frame 10 is adjusted by means of the adjusting bolt 11, which is more convenient when in use.

[0024] The implementation principle of a Hall rotary encoder in the embodiment of the present application is as follows: by installing the connecting frame 3 on the surface of the encoder body 1, a slider 4 is installed at one end of the connecting frame 3, and a fixing frame 5 is slidably connected to the surface of the slider 4, and the bottom end of the fixing frame 5 is fixed to the inner wall of the device, so that the two ends of the encoder body 1 can be limited by the connecting frame 3, and the connecting frame 3 can be conveniently moved by means of the slider 4 and the fixing frame 5, which is more convenient when the encoder body 1 is disassembled. A card slot 6 is provided on the inner wall of the connecting frame 3, and a limiting block 7 is clamped on the inner wall of the card slot 6.

The inner wall of the adjusting frame 10 is rotatably connected to a limiting roller 12, so that the top of the connecting head 2 can be pushed with the help of the limiting roller 12, thereby keeping the connecting head 2 in contact with the inside of the device, avoiding the situation where the connecting head 2 becomes loose and the encoder body 1 is difficult to connect with the device.
