[0002] An encoder is a device that compiles and converts signals or data into a signal form that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code disk, and the latter is called a yardstick. According to the readout method, the encoder can be divided into contact and non-contact types. According to the working principle, the encoder can be divided into incremental and absolute types. China has authorized a utility model patent (Announcement No.: CN218673684U) to disclose a magnetic encoder. By providing a mounting accessory structure, it is easy to fix and use. The middle disc of the mounting accessory is fixedly connected to the body shell by assembly screws, so that the middle disc is easy to install and fix, so that the bent fixing plates at both ends of the middle disc are easy to install and use stably, and the bent fixing plates are in an arc state, so that external personnel damage is effectively avoided when the whole is fixed.

[0003] The bent mounting plate in the prior art is fixed in position after being connected to the encoder and cannot be fine-tuned according to the actual situation of the mechanical equipment or changes in the installation environment. This limits the installation flexibility of the encoder and increases the installation difficulty and cost. Therefore, an electromagnetic encoder is proposed to address the above situation.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 , an electromagnetic encoder, comprising an electromagnetic encoder body 1, on which a disc 2 is arranged, specifically, as Figure 1 As shown, a mounting circular hole is formed through the top of the disc 2, and the disc 2 is mounted on the electromagnetic encoder body 1 by bolts.

[0025] The electromagnetic encoder body 1 is a prior art, such as the internally controlled optical electromagnetic incremental encoder OVW2-10-2MHT.

[0026] A fixing component 3 is arranged on the disc 2 .

[0027] The fixing assembly 3 comprises a rectangular plate 4 fixedly connected to the disc 2 . The rectangular plate 4 has a slot 401 . Both sides of the rectangular plate 4 are provided with a row of limiting holes 402 communicating with the slot 401 .

[0028] The fixing assembly 3 includes a bending plate 5, a plug block 6 is provided on one side of the bending plate 5, and a pair of second springs 602 are provided on the plug block 6. Specifically, Figure 2 and Figure 3 As shown, a pair of circular grooves 601 are formed on the insert block 6, and the second spring 602 is arranged in the circular grooves 601. The radius of the circular grooves 601, the limiting rod 603 and the limiting hole 402 are the same.

[0029] One end of a pair of second springs 602 is fixedly connected to a limiting rod 603 , the insert block 6 is slidably matched with the slot 401 , and the limiting rod 603 passes through the limiting hole 402 .

[0030] When in use, the staff presses the two limit rods 603 protruding from the outside of the rectangular plate 4 with their fingers. After being squeezed, the limit rods 603 will shrink into the circular groove 601 through the limit holes 402. During this process, the second spring 602 is in a compressed state, and the plug block 6 can be slid at this time. When the limit rod 603 moves to the next limit hole 402, the second spring 602 is reset, so that the limit rod 603 can be extended from the limit hole 402 at that location to realize the positioning of the plug block 6, thereby realizing the adjustment of the distance between the bending plate 5 and the mechanical equipment.

[0031] Four movable grooves 501 are provided on the side of the bending plate 5 away from the insert block 6, and first springs 502 are provided in the four movable grooves 501. The four first springs 502 are fixedly connected with movable blocks 503, and the movable blocks 503 are slidably matched with the movable grooves 501. The four movable blocks 503 are fixedly connected with an assembly plate 504, and a rubber pad is provided on the side of the assembly plate 504 away from the bending plate 5.

[0032] Specifically, Figure 2 and Figure 4 As shown, three mounting holes are vertically and equidistantly formed on the bending plate 5 and the assembly plate 504 .

[0033] Furthermore, the installation holes are provided for connection with mechanical equipment.

[0034] When the bending plate 5 is connected to the mechanical equipment by bolts, during this process, the assembly plate 504 contacts the mechanical equipment. When there is still a slight distance between the bending plate 5 and the mechanical equipment, the assembly plate 504 can be used as a support to ensure the stability of the bending plate 5 after connection. At the same time, when the assembly plate 504 can be squeezed by the mechanical equipment, the movable block 503 squeezes the first spring 502 to shrink into the movable groove 501, so that the assembly plate 504 and the mechanical equipment fit tightly, ensuring that the adjusted bending plate 5 can fit tightly to the mechanical equipment, eliminating the installation gap, thereby improving the accuracy of the installation, which not only helps to ensure the precise fit between the electromagnetic encoder body 1 and the mechanical equipment, but also can improve the measurement accuracy and stability.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
