Description

Technical Field

[0001] The utility model relates to the technical field of encoder protection, in particular to a motor encoder with a protection function. Background Art

[0002] A motor encoder is an electromechanical device whose main function is to convert mechanical motion into electrical signals, which are used by the control system to monitor application-specific parameters such as position and speed, and make adjustments when necessary to keep the machine running as required. The motor encoder can monitor the position information of the motor rotor in real time to ensure that all movements are performed at the correct position and speed. In addition, the motor encoder can also achieve speed feedback control, precise positioning and position control, improve system efficiency and improve product quality;

[0003] Encoder connection cable failure. This type of failure has the highest probability of occurring and is often encountered during maintenance. It should be the priority factor. The cause of the failure is generally cable breakage, short circuit or poor contact. At this time, the cable or interface needs to be replaced. Special attention should be paid to whether the cable is not fixed tightly, causing looseness and causing open welding or breakage. Since the encoder is connected to the external device through an interface, it is easy to cause the joint and interface to loosen. For this reason, we propose a motor encoder with a protective function. Utility Model Content

[0004] The purpose of the utility model is to provide a motor encoder with a protection function, which solves the problems in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solutions: a motor encoder with a protective function, comprising a motor encoder body and a connector, wherein an encoder interface is fixedly mounted on the outer wall of the motor encoder body, the connector is plugged into the encoder interface, and a limiting mechanism is arranged between the encoder interface and the connector;

[0006] The limiting mechanism includes a fixed block and a movable ring. The number of the fixed blocks is four. Connecting rods are fixedly connected between the four fixed blocks and the encoder interface. A contraction groove is provided at the bottom end of the fixed block. The limiting block is inserted in the contraction groove. A connecting rope is fixedly connected to the top of the limiting block. A spring is surrounded by the outside of the connecting rope. The spring is fixedly installed between the top of the limiting block and the top of the inner wall of the contraction groove. A rope hole is provided at the top of the inner wall of the contraction groove. The connecting rope movably passes through the rope hole. The movable ring is movably sleeved on the outside of the encoder interface. One end of the connecting rope is fixedly installed on one side of the movable ring. The limiting block is clamped on one side of the joint.

[0007] Preferably, the outer side of the limit block is an inclined surface close to the bottom end, and the limit block is adapted to the contraction groove. By setting the limit block, the joint can be limited to improve the stability of the joint in the encoder interface.

[0008] Preferably, a guide roller is fixedly mounted on the top of the fixed block, and the connecting rope is in contact with the outer wall surface of the guide roller. By providing the guide roller, a certain guiding effect can be played on the connecting rope.

[0009] Preferably, the connecting rope is matched with the rope hole.

[0010] Preferably, a wall pad is fixedly installed on the inner wall of the moving ring, and the wall pad is in close contact with the outer wall surface of the encoder interface. The material of the wall pad is wear-resistant rubber. By setting the wall pad, the tightness of the connection between the moving ring and the encoder interface can be increased, thereby improving the stability of the moving ring on the encoder interface.

[0011] Preferably, a protective ring plate is fixedly mounted on one end of the encoder interface, a protective ring groove is formed on the outer wall of the joint, and the protective ring plate is inserted into the protective ring groove.

[0012] The utility model provides a motor encoder with a protective function. The motor encoder with a protective function has the following beneficial effects:

[0013] (1) The motor encoder with a protective function can make the limit block clamped at the rear end of the joint by setting a limit mechanism to limit and fix the joint, thereby improving the stability of the joint after being inserted into the encoder interface, avoiding the joint from loosening and affecting the normal operation of the motor encoder body, and solving the problem that the existing motor encoder is easily loosened when connected to an external device through an interface, resulting in poor contact and making the motor encoder prone to failure;

[0014] (2) The motor encoder with protection function can provide a certain waterproof effect between the connector and the encoder interface by setting a protection ring plate and a protection ring groove, thereby preventing rainwater from entering the encoder interface and causing short circuit or leakage, and has strong practicality.

[0023] Embodiment 1:

[0024] The motor encoder with protection function provided by the utility model is preferably implemented as follows Figures 1 to 4 As shown: a motor encoder with a protective function, comprising a motor encoder body 1 and a connector 3, wherein an encoder interface 2 is fixedly mounted on the outer wall of the motor encoder body 1, the connector 3 is plugged into the encoder interface 2, and a limiting mechanism 4 is arranged between the encoder interface 2 and the connector 3;

[0025] The limiting mechanism 4 includes a fixed block 402 and a movable ring 409. The number of the fixed blocks 402 is four. A connecting rod 401 is fixedly connected between the four fixed blocks 402 and the encoder interface 2. A contraction groove 404 is provided at the bottom end of the fixed block 402. A limiting block 403 is inserted in the contraction groove 404. A connecting rope 406 is fixedly connected to the top of the limiting block 403. A spring 405 is surrounded by the outside of the connecting rope 406. The spring 405 is fixedly installed between the top of the limiting block 403 and the top of the inner wall of the contraction groove 404. A rope hole 407 is provided on the top of the inner wall of the contraction groove 404. The connecting rope 406 movably passes through the rope hole 407. The movable ring 409 is movably sleeved on the outside of the encoder interface 2. One end of the connecting rope 406 is fixedly installed on one side of the movable ring 409. The limiting block 403 is clamped on one side of the joint 3.

[0026] Specifically, in the above technical solution, when the connector 3 is inserted into the encoder interface 2, the connector 3 will squeeze the limit block 403 to move upward, so that the limit block 403 shrinks into the contraction groove 404, compressing the spring 405. When the connector 3 is fully inserted into the encoder interface 2, the connector 3 is no longer subjected to force on the limit block 403. At this time, the limit block 403 will extend out of the contraction groove 404 under the reset force of the spring 405, so that the limit block 403 is clamped at the rear end of the connector 3, and the connector 3 is limited and fixed, thereby improving the stability of the connector 3 after being inserted into the encoder interface 2, avoiding the loosening of the connector 3 and affecting the normal operation of the motor encoder body 1, and solving the problem that the existing motor encoder is connected to the external device through the interface, which is easy to cause the connector 3 and the interface to loosen, resulting in poor contact and making the motor encoder prone to failure.

[0027] Furthermore, the outer side of the limit block 403 near the bottom end surface is an inclined surface, and the limit block 403 is adapted to the contraction groove 404;

[0028] By setting the limit block 403 , the connector 3 can be limited, thereby improving the stability of the connector 3 in the encoder interface 2 .

[0029] Furthermore, a guide roller 408 is fixedly mounted on the top of the fixed block 402, and the connecting rope 406 is in contact with the outer wall surface of the guide roller 408;

[0030] Among them, by providing the guide roller 408, a certain guiding effect can be played on the connecting rope 406.

[0031] Furthermore, the connecting rope 406 is adapted to the rope hole 407 .

[0032] Furthermore, a wall pad 410 is fixedly installed on the inner wall of the moving ring 409, and the wall pad 410 is in close contact with the outer wall surface of the encoder interface 2, and the material of the wall pad 410 is wear-resistant rubber;

[0033] Among them, by providing the wall pad 410 , the tightness of the connection between the moving ring 409 and the encoder interface 2 can be increased, thereby improving the stability of the moving ring 409 on the encoder interface 2 .

[0036] Specifically, the above technical solution provides a protective ring plate 5 and a protective ring groove 6 to provide a certain degree of waterproofing between the connector 3 and the encoder interface 2, thereby preventing rainwater from entering the encoder interface 2 and causing short circuit or leakage, and has strong practicality.
