Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor auxiliary parts, in particular to a motor locking device. Background Art
[0002] Hollow motors are needed in the working process of many equipment. Hollow motors are divided into different types, including those without locking function after stalling and those with locking function. Hollow motors without locking function after stalling are usually more affordable, while hollow motors with locking function can lock the rotor position after stalling, providing higher precision and stability, but the corresponding price will be higher. Motors with locking function will be more expensive, so some factories cannot purchase and use them due to limited purchasing costs, which makes the operation of the equipment unable to meet the needs of users. Utility Model Content
[0003] The main purpose of the utility model is to provide a motor locking device, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A motor locking device comprises a mounting plate, side plates are fixed at both ends of the bottom of the mounting plate, a mounting seat is fixed at the bottom between the side plates, a hollow motor is mounted at the bottom of the mounting seat, the output end of the hollow motor is in communication with the mounting seat, a coupling is connected to the output end of the hollow motor passing through the mounting seat, a connecting block is connected to the coupling, a positioning hole is drilled on the side wall of the connecting block, a rotating shaft is fixed on the top of the connecting block, the rotating shaft is in communication with the mounting plate, a fixing frame is fixed on the inner wall of one side of the side plate, a sensor is mounted on the fixing frame, an induction sheet is provided at the position of the sensor, a cylinder is fixed on the side wall of the side plate located below the fixing frame, and a positioning block is fixed to the telescopic end of the cylinder.
[0006] Preferably, the position of the positioning block is parallel to the position of the positioning hole, and one end of the positioning block away from the cylinder is inserted into the interior of the positioning hole.
[0007] Preferably, the induction sheet is mounted on the outer wall of the bottom end of the rotating shaft by means of screws.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] The hollow motor drives the rotating shaft to rotate through the coupling and the connecting block. When it needs to stop and lock, the sensor is energized. When the rotating shaft drives the induction plate to rotate to the position of the sensor, the sensor can receive the induction signal and send a control signal to the cylinder. The opening of the cylinder drives the positioning block to extend and insert it into the positioning hole of the connecting block, thereby positioning and locking the rotating shaft. When the positioning block is inserted into the positioning hole, the hollow motor is powered off, and all the locking work can be completed. This design enables the hollow motor to have locking work, and the cost is relatively low, and it is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Working principle:
[0020] The hollow motor 4 drives the rotating shaft 7 to rotate through the coupling 5 and the connecting block 6. When it needs to stop and lock, the sensor 11 is energized.
