Description

Technical Field

[0001] The utility model relates to the field of magnetic encoders, in particular to a magnetic ring component used for magnetic encoders. Background Art

[0002] At present, a Chinese utility model with the announcement number CN216483112U discloses a magnetic ring encoder, including a magnetic ring and a reading head assembly, wherein the reading head assembly includes a base, a main board, a shell and a mounting plate, wherein the base and the shell are fixedly connected, the main board is located in the base, a cable connector is fixed on the shell, and the cable connector is connected to the main board through a line; the mounting plate is L-shaped, and the mounting plate has a vertically arranged horizontal plate and a vertical plate, and the horizontal plate and the vertical plate are both provided with perforations, and the horizontal plate and the vertical plate are connected to the shell through connecting screws. By separating the mounting plate from the shell, the original four specifications and models with different orientations and directions are unified into one model, which facilitates the selection and procurement and the production organization of the manufacturer. When in use, the overall structural design is more flexible. At the same time, the connection holes on the shell can be used to develop the connection plate by yourself to simplify the overall installation structure.

[0003] The existing magnetic ring assembly is not easy to assemble and disassemble. Generally, the magnetic ring is fixedly installed on the rotating shaft by multiple bolts. When disassembling and assembling the magnetic ring, tools are needed to disassemble and assemble the multiple bolts. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the work efficiency. The magnetic ring cannot be replaced. Generally, the magnetic ring assembly includes a disk seat and a magnetic ring. The magnetic ring and the disk seat are fixedly installed and difficult to disassemble. When the magnetic ring is damaged, the entire magnetic ring assembly can only be replaced, which increases the subsequent maintenance cost and reduces the practicality and applicability. In order to solve the above-mentioned problems, we propose a magnetic ring assembly for a magnetic encoder. Utility Model Content

[0004] The utility model aims to provide a magnetic ring assembly for a magnetic encoder, which has the advantages of being easy to assemble and disassemble and capable of replacing the magnetic ring.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a magnetic ring assembly for a magnetic encoder, comprising a first disk seat, a fixed cylinder bolted to the surface of the first disk seat, a rotating cylinder threadedly connected to the surface of the fixed cylinder, an elastic rod bolted to the surface of the fixed cylinder, and the elastic rod is located inside the rotating cylinder, a second disk seat is arranged on the surface of the first disk seat, bolts are threadedly connected between the first disk seat and the second disk seat, a magnetic ring is arranged between the first disk seat and the second disk seat, and a magnetic column is embedded in the surface of the first disk seat.

[0006] By adopting the above technical scheme, after the disc seat is installed on the rotating shaft, the rotating cylinder is rotated, and the rotating cylinder rotates to move the rotating cylinder. The movement of the rotating cylinder causes the inner wall of the rotating cylinder to squeeze the elastic rod, so that the elastic rod squeezes the rotating shaft to fix the magnetic ring assembly. When disassembling, the rotating cylinder is rotated in the opposite direction to release the inner wall of the rotating cylinder from squeezing the elastic rod, so that the elastic rod relaxes from squeezing the rotating shaft, and the magnetic ring assembly is removed. This method can facilitate the purpose of assembly and disassembly, reduce the workload, and improve the efficiency of assembly and disassembly. The bolts are removed by using tools, and then the second disc seat is removed, the magnetic ring is removed, and then the new magnetic ring is installed into the first disc seat in accordance with the positioning groove, and then the second disc seat is pressed, the bolts are installed and tightened to complete the replacement, thereby achieving the purpose of facilitating the replacement of the magnetic ring, reducing the cost of use, and improving practicality and applicability.

[0007] The utility model is further configured as follows: an anti-slip sleeve is fixedly sleeved on the surface of the rotating cylinder.

[0008] By adopting the above technical solution, the anti-skid cover is provided to prevent the hand from slipping and facilitate operation.

[0009] The utility model is further configured as follows: the number of the elastic rods is four, and the four elastic rods are evenly distributed on the surface of the fixing tube.

[0010] By adopting the above technical solution, the number of elastic rods is set to four, and the four elastic rods are evenly distributed on the surface of the fixing tube, thereby ensuring the stability of the fixing.

[0011] The utility model is further configured as follows: a rubber pad is bonded to one end of the elastic rod.

[0012] By adopting the above technical solution and arranging the rubber pad, damage to the rotating shaft can be prevented and the rotating shaft can be protected.

[0013] The utility model is further configured that: the inner walls of the first disc seat and the second disc seat are both provided with limiting grooves.

[0014] By adopting the above technical solution, the first disc seat and the second disc seat are prevented from idling by providing the limiting groove.

[0015] The utility model is further configured as follows: the bolt is a hexagon socket bolt.

[0016] By adopting the technical solution, the bolts are set as hexagon socket bolts, which is easy to use.

[0017] The utility model is further configured as follows: a positioning groove is provided on the inner wall of the first disc seat.

[0018] By adopting the above technical solution and providing the positioning groove, the gear ring can be easily positioned to prevent deviation.

[0019] The utility model is further configured as follows: a gasket is slidably sleeved on the surface of the bolt.

[0020] By adopting the above technical solution, gaskets are provided to prevent the bolts from loosening and ensure stability.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. The utility model installs the disc seat on the rotating shaft, rotates the rotating drum, and the rotating drum rotates to move the rotating drum. The movement of the rotating drum causes the inner wall of the rotating drum to press the elastic rod, and the elastic rod presses the rotating shaft to fix the magnetic ring assembly. When disassembling, the rotating drum is rotated in the opposite direction to release the inner wall of the rotating drum from pressing the elastic rod, and the elastic rod releases the pressing on the rotating shaft to remove the magnetic ring assembly. The utility model can facilitate the purpose of assembly and disassembly, reduce the workload, and improve the efficiency of assembly and disassembly.

[0023] 2. The utility model uses tools to disassemble the bolts, then remove the second disc seat, remove the magnetic ring, and then install the new magnetic ring into the first disc seat in cooperation with the positioning groove, and then press the second disc seat, install and tighten the bolts to complete the replacement, thereby achieving the purpose of facilitating the replacement of the magnetic ring, reducing the use cost, and improving practicality and applicability.
