Description

Technical Field

[0002] A code disk is a digital encoder used to measure angular displacement. It boasts advantages such as high resolution, high measurement accuracy, and reliable operation, making it one of the most commonly used displacement sensors for measuring shaft angular position. Code disks are divided into two types: absolute encoders and incremental encoders. The former directly outputs a digital code corresponding to the angular position; the latter uses a calculation system to add or subtract the pulse increments generated by rotating the code disk relative to a certain reference number.

[0003] The code disk is mounted on a rotating shaft. When the code disk is damaged or needs to be replaced or maintained, the code disk is difficult to disassemble, resulting in long maintenance time and high downtime costs. The environment where the drive structure is located may contain oil, dust, etc., and the device has no external protective structure, which can easily contaminate the surface or reflective surface of the code disk, leading to signal attenuation or failure of the code disk.

[0031] In this embodiment, the outer casing 1 is installed on the outside of the device and used in conjunction with the sealing cover 2 to protect the internal device (code disk body 21) and reduce dust adhesion.

[0036] Furthermore, the light source board 17 is connected to the first connection port 15 through the connecting plate 16. The first connection port 15 and the second connection port 18 have the same structure. The light source board 17 and the parallel grating 19 are on the same straight line.

[0037] Furthermore, the connecting ring 20 and the fixed ring 22 are interlocked, the code disk body 21 and the rotating rod 12 are interlocked, the insertion plate 24 on the first collar 23 and the insertion groove 26 on the second collar 25 are interlocked, and the screw 27 and the top of the rotating rod 12 are threaded.

[0038] Furthermore, the photosensitive element 28 and the parallel grating 19 are positioned on the same straight line, and the sliding block 31 is symmetrically installed on the upper and lower sides of the device plate 29 with the device plate 29 as the center reference. The sliding block 31 and the third limiting groove 8 form a sliding connection.

[0039] In this embodiment, sliding blocks 14 are installed on both sides of the mounting plate 13. The sliding blocks 14 slide in the first limiting groove 6 to limit the position of the mounting plate 13. The first connection port 15 on the mounting plate 13 realizes the quick installation and removal of the light source plate 17 through the connecting plate 16. The second connection port 18 is used for the quick installation and removal of the parallel grating 19. The rotating rod 12 is connected to the insertion rod 11 through the plug-in structure on it. The rotating motor 9 drives the rotating rod 12 to rotate. The connecting ring 20 is fixed on the rotating rod 12. The side end of the code disk body 21 is equipped with a fixing ring 22. The fixing ring 22 and the connecting ring 20 are plugged in to pre-fix the code disk body 21 on the rotating rod 12. The first collar 23 is equipped with an insertion plate 24. The second collar 25 is provided with an insertion groove 26. The code disk body 21 is fixed for the second time through the plug-in cooperation of the insertion plate 24 and the insertion groove 26. The rotating motor 9 drives the rotating rod 12 to rotate, which drives the code disk body 21 fixed on it to rotate.

[0040] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: An outer shell 1 is added to the outside of the code disk body 21. The outer shell 1 and the sealing cover 2 are connected by threads. A connecting hole 3 is provided inside the sealing cover 2. The rotating rod 12 passes through the connecting hole 3 of the sealing cover 2 and extends into the interior of the outer shell 1, driving the code disk body 21 inside to rotate. The function of the outer shell 1 is to protect the code disk body 21 and prevent dust from accumulating on it. The rotating motor 9 is connected to the insert rod 11 on the rotating rod 12 through a connecting rod 10. Mounting plates 13 are installed on both sides... A sliding block 14 slides in the first limiting groove 6, restricting the position of the mounting plate 13. The first connecting port 15 on the mounting plate 13 enables the quick installation and removal of the light source plate 17 through the connecting plate 16; the second connecting port 18 is used for the quick installation and removal of the parallel grating 19. The connecting ring 20 is fixed to the rotating rod 12. A fixing ring 22 is installed on the side of the code disk body 21. The fixing ring 22 and the connecting ring 20 are inserted and fitted to pre-fix the code disk body 21 on the rotating rod 12. An insertion plate 24 is installed on the upper end of the first collar 23, and the second collar... The upper end of 25 has an insertion slot 26. The code disk body 21 is fixed for the second time by the insertion plate 24 and the insertion slot 26 being inserted and connected. The top end of the rotating rod 12 is threadedly connected to the screw 27. The rotating motor 9 is separated from the rotating rod 12 (that is, the insertion and engagement of the connecting rod 10 and the insertion rod 11 is broken). The rotating plate 4 at the upper end of the sealing cover 2 is rotated, and the sealing cover 2 is unscrewed to release its threaded connection with the outer shell 1 and remove it from the position restriction of the outer shell 1. The rotating rod 12 and the code disk body 21 at its upper end are then pulled out of the outer shell 1 as a whole and the rotating rod 12 is disassembled. The screw 27 at the top separates the insertion engagement of the first collar 23 and the second collar 25 (i.e., disconnects the connection between the insertion plate 24 and the insertion slot 26), and pulls the code disk body 21 out of the rotating rod 12. At this time, the fixing ring 22 on the side of the code disk body 21 will disengage from the connecting ring 20 on the rotating rod 12. Thus, the code disk body 21 is completely disassembled and can be quickly replaced. When disassembling and installing other components (light source plate 17, parallel grating 19), quick disassembly and installation can be achieved through the first connection port 15 and the second connection port 18 on the mounting plate 13.
