Description

Technical Field

[0001] This utility model relates to the field of encoder technology, and more specifically to an inductive encoder that is easy to install. Background Technology

[0002] Inductive encoders are position detection devices based on the principle of electromagnetic induction. They are widely used in industrial automation, robot joint positioning, CNC machine tools, servo motors, and other scenarios requiring high-precision angle or linear displacement measurement. Compared to optical encoders, they utilize non-contact signal sensing, offering stronger resistance to contamination and vibration, making them suitable for harsh industrial environments.

[0003] As shown in the prior art of publication CN211877056U, although this prior art achieves the effect of simple and effective installation of the encoder body and easy disassembly by setting a fixing device on the other side surface of the encoder body, and the fixing device includes a fixing block, with one side surface of the fixing block fixedly connected to the other side surface of the encoder body, the prior art uses a spring for limiting and fixing. However, the elastic potential energy of the spring weakens, affecting the fixing effect, which in turn affects the assembly stability of the encoder. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides an inductive encoder that is easy to install. By setting the threaded directions of the two ends of the adjusting rod to opposite directions, the adjusting rod can drive the two adjusting seats to move inward or outward synchronously, thereby facilitating the adjustment of the distance between the two clamping plates. This achieves the effect of convenient disassembly and assembly of the encoder body. Furthermore, the adjusting rod, through the engagement of the ratchet and the limiting teeth, can effectively prevent the adjusting rod from rotating, thus ensuring the clamping stability of the clamping plates and preventing the encoder body from loosening. The overall structural stability can effectively guarantee the performance of the encoder, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an inductive encoder that is easy to install, comprising a fixing plate and an encoder body mounted on the top of the fixing plate, wherein the bottom of the fixing plate is provided with mounting parts for convenient assembly of the encoder body;

[0006] The mounting component includes a hollow column at the bottom of the fixed plate, and two connecting plates for connecting the fixed plate are installed on the top of the hollow column. An adjusting rod is installed inside the hollow column through a bearing, and the threads at both ends of the adjusting rod are opposite in direction.

[0007] Both ends of the adjusting rod are threaded to adjusting seats. The bottom of the adjusting seat is fitted with an L-shaped clamp. A limiting component is provided between the two adjusting seats to prevent the adjusting rod from rotating.

[0008] In a preferred embodiment, the limiting member includes a movable column disposed at the top of the adjusting rod, a positioning frame installed at the bottom of the movable column, a support column installed at the rear side of the bottom end of the positioning frame, a support seat sleeved on both ends of the support column, a common limiting tooth installed at the bottom of the two support seats, and a spring for connecting the positioning frame at the top of the rear end of the limiting tooth.

[0009] The bottom of the limiting tooth is provided with a ratchet, and the bottom end of the limiting tooth extends into the inside of the top of the ratchet.

[0010] In a preferred embodiment, a screw is mounted on the top of the movable column via a bearing. The top of the screw passes through the hollow column and extends to the outside of the top of the hollow column, and the screw is threadedly connected to the hollow column.

[0011] In a preferred embodiment, the movable column has a positioning hole on its outside, and a positioning post is provided inside the top of the positioning hole. Both ends of the positioning post are fixed to the inner wall of the hollow column.

[0012] In a preferred embodiment, the bottom of the adjusting rod is provided with a guide rod, both ends of which are fixed to the inner wall of the hollow column, and the adjusting seat is sleeved on the outside of the guide rod.

[0013] In a preferred embodiment, a slide rail is provided at the bottom of the hollow column, and two clamping plates are respectively provided inside the two ends of the slide rail.

[0014] In a preferred embodiment, the hollow column has a groove on its outside and a handle inside the groove. The handle passes through the hollow column and is fixed together with the adjusting rod.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] By setting the thread directions of the two ends of the adjusting rod to opposite directions, the adjusting rod can drive the two adjusting seats to move inward or outward synchronously, thereby facilitating the adjustment of the distance between the two clamping plates. This achieves the effect of convenient disassembly and assembly of the encoder body. Furthermore, the adjusting rod can effectively prevent rotation by means of the ratchet and the limiting teeth, thus ensuring the clamping stability of the clamping plates and preventing the encoder body from loosening. The overall structural stability can effectively guarantee the performance of the device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figure 1-5 This utility model provides an inductive encoder that is easy to install, including a fixing plate 1 and an encoder body 2 mounted on the top of the fixing plate 1. The bottom of the fixing plate 1 is provided with a mounting component for easy assembly of the encoder body 2. The mounting component includes a hollow column 3 located at the bottom of the fixing plate 1, and two connecting plates 4 for connecting the fixing plate 1 are mounted on the top of the hollow column 3. An adjusting rod 5 is installed inside the hollow column 3 and is movably connected by a bearing. The threads at both ends of the adjusting rod 5 are opposite in direction. Adjusting seats 6 are threaded to the outside of both ends of the adjusting rod 5. An L-shaped clamping plate 7 is installed at the bottom of the adjusting seat 6. A limiting component is provided between the two adjusting seats 6 to prevent the adjusting rod 5 from rotating.

[0025] When assembling the encoder body 2, the adjusting rod 5 can be rotated to move the two threaded adjusting seats 6. Because the threads at both ends of the adjusting rod 5 are opposite in direction, the two adjusting seats 6 can move synchronously inward or outward along the adjusting rod 5, thus facilitating the adjustment of the distance between the two clamping plates 7 and achieving convenient disassembly and assembly of the fixing plate 1 and the encoder body 2. To ensure smooth movement of the clamping plates 7, a slide rail 19 is provided at the bottom of the hollow column 3, with the two clamping plates 7 respectively located inside both ends of the slide rail 19. This allows the clamping plates 7 to be adjusted within the slide rail 19, preventing the hollow column 3 from obstructing their movement. Furthermore, to ensure stability during the movement of the adjusting seats 6, a guide rod 18 is provided at the bottom of the adjusting rod 5. Both ends of the guide rod 18 are fixed to the inner wall of the hollow column 3, and the adjusting seats 6 are sleeved on the outside of the guide rod 18. In this way, the guide rod 18 can limit and guide the adjustment seat 6, so that the adjustment seat 6 can move along the guide rod 18, ensuring the stability of the adjustment seat 6 during the movement and avoiding the adjustment seat 6 from tilting or shaking during the movement.

[0026] Meanwhile, to improve the convenience of rotating the adjusting rod 5, a groove 20 is provided on the outside of the hollow column 3, and a handle 21 is provided inside the groove 20. The handle 21 passes through the hollow column 3 and is fixed together with the adjusting rod 5. In this way, the adjusting rod 5 can be driven by rotating the handle 21, and since the handle 21 is located on the outside of the hollow column 3, it can effectively improve the convenience for the operator to drive the adjusting rod 5.

[0027] To prevent the adjusting rod 5 from rotating after adjustment, a limiting component is used to limit its movement. This limiting component includes a movable column 8 at the top of the adjusting rod 5, a positioning frame 9 at its bottom, and a support column 10 at the rear bottom of the positioning frame 9. Support seats 11 are fitted onto the outer sides of both ends of the support column 10, and the same limiting tooth 12 is installed at the bottom of both support seats 11. A spring 13 for connecting the positioning frame 9 is located at the top rear end of the limiting tooth 12. A ratchet 14 is located at the bottom of the limiting tooth 12, and the bottom end of the limiting tooth 12 extends into the interior of the ratchet 14. A screw 15, connected movably by a bearing, is installed at the top of the movable column 8. The top end of the screw 15 passes through the hollow column 3 and extends to the outside of the top end of the hollow column 3, and the screw 15 is threadedly connected to the hollow column 3.

[0028] In this way, the ratchet 14 can be connected to the adjusting rod 5, so that the adjusting rod 5 can rotate together with the ratchet 14. Since the ratchet 14 is in contact with the limiting tooth 12, the ratchet 14 can reciprocate to move the limiting tooth 12 which is limited by the spring 13. However, when the ratchet 14 rotates, the limiting tooth 12 will engage the limiting ratchet 14, thereby preventing the adjusting rod 5 from rotating and ensuring the fixing effect of the clamp 7.

[0029] When the adjusting rod 5 needs to be rotated, the operator rotates the screw 15, which is threadedly connected to the hollow column 3. The screw 15 then moves the movable column 8 upwards, causing the limiting tooth 12 to move upwards and separate from the ratchet 14. This allows for the rotation of the unrestricted adjusting rod 5. To prevent the movable column 8 from rotating during its upward movement, a limiting mechanism is needed. Therefore, a positioning hole 16 is provided on the outside of the movable column 8, and a positioning post 17 is located inside the top of the positioning hole 16. Both ends of the positioning post 17 are fixed to the inner wall of the hollow column 3. This engagement between the positioning post 17 and the positioning hole 16 limits the movement of the movable column 8, ensuring stable vertical movement and preventing the limiting tooth 12 from rotating. This ensures the precise engagement of the limiting tooth 12 with the ratchet 14.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
