Description

Technical Field

[0001] This utility model relates to the field of servo motor technology, and specifically to a brake for a servo motor. Background Technology

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor with indirect speed change. Servo motors can control speed and have very accurate positioning. They can convert voltage signals into torque and speed to drive the controlled object.

[0003] The existing braking principle of servo motors is that when current flows through the magnetic coil of the electromagnetic brake, the electromagnetic force attracts the brake pads, causing them to release the brake disc, thus allowing the drive shaft to drive the brake disc for normal operation or starting. When the servo motor drives a heavy load or drives the load through a long shaft for braking, it will experience swaying due to inertia, etc., requiring additional braking equipment to improve the stability of the servo motor. Therefore, a brake for servo motors is proposed, in which a compression spring pushes the iron inner tube to extend, so that one end of it is inserted into the circular tooth groove to brake the brake disc, thereby braking the output shaft of the servo motor body. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a brake for a servo motor. A compression spring pushes an iron inner tube to extend, so that one end of it is inserted into a circular toothed groove to brake the brake disc, thereby braking the output shaft of the servo motor body.

[0005] The technical solution adopted by this utility model to solve its technical problem is a brake for a servo motor, including a servo motor body. A telescopic component is provided on the top of the servo motor body. The telescopic component is composed of an insulating sleeve, an iron inner tube, a compression spring, an iron rod, and an electromagnetic coil.

[0006] A braking assembly is provided on one side of the output shaft of the servo motor body. The braking assembly consists of a bushing, a brake disc, and a connecting rod. A support base is provided at the bottom of the insulating sleeve. The support base is fixed to the top of the servo motor body by bolts. The iron inner tube is fixedly sleeved inside the insulating sleeve. The electromagnetic coil is sleeved outside the iron inner tube. The compression spring is fixed inside the iron inner tube by bolts. The iron rod is sleeved at one end of the iron inner tube. The bushing is fixedly sleeved on one side of the output shaft of the servo motor body by a flat key. The brake disc is fixedly sleeved outside the bushing. The connecting rod is fixedly set at one end of the bushing.

[0007] By adopting the above technical solution, the compression spring pushes the iron rod to extend, and the brake disc and the bushing on the output shaft of the servo motor body brake the output shaft of the servo motor body. After the electromagnetic coil is energized, the iron inner tube generates magnetism, attracting the extended iron rod into the iron inner tube so that it will not affect the rotation of the output shaft of the servo motor body.

[0008] Specifically, a keyway is provided at the top of the connecting rod.

[0009] Specifically, one end of the iron column is provided with a locking tooth, and the brake disc has a circular tooth groove corresponding to the locking tooth on the side near the servo motor body.

[0010] The beneficial effects of this utility model are:

[0011] The present invention discloses a brake for a servo motor. When the servo motor body stops, the power supply to the electromagnetic coil is disconnected, and the compression spring pushes the iron inner tube to extend, so that the retaining teeth at one end of the iron inner tube are inserted into the circular tooth groove on one side of the brake disc. The retaining teeth mesh with the iron column rod to brake the brake disc, thereby braking the output shaft of the servo motor body by means of the sleeve.

[0012] The present invention relates to a brake for a servo motor. When the servo motor body is working, it supplies power to the electromagnetic coil. After the electromagnetic coil is energized, the iron inner tube generates magnetism, attracting the iron rod to the iron inner tube so that it does not affect the rotation of the output shaft of the servo motor body.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] A compression spring pushes the inner iron tube outward, causing one end to insert into a circular toothed groove to brake the brake disc, thereby braking the output shaft of the servo motor. Figure 1-5 As shown, the present invention provides a brake for a servo motor, including a servo motor body 1. A telescopic component 2 is provided on the top of the servo motor body 1. The telescopic component 2 is composed of an insulating sleeve 201, an iron inner tube 202, a compression spring 203, an iron rod 204, and an electromagnetic coil 205.

[0022] A braking assembly 3 is provided on the output shaft on one side of the servo motor body 1. The braking assembly 3 consists of a bushing 301, a brake disc 302, and a connecting rod 303. A support base 4 is provided at the bottom of the insulating sleeve 201. The support base 4 is fixed to the top of the servo motor body 1 by bolts. The iron inner tube 202 is fixedly sleeved inside the insulating sleeve 201. The electromagnetic coil 205 is sleeved outside the iron inner tube 202. The compression spring 203 is fixed inside the iron inner tube 202 by bolts. The iron rod 204 is sleeved at one end of the iron inner tube 202. The bushing 301 is fixedly sleeved on the output shaft on one side of the servo motor body 1 by a flat key. The brake disc 302 is fixedly sleeved outside the bushing 301. The connecting rod 303 is fixedly provided at one end of the bushing 301.

[0023] In use, the compression spring 203 pushes the iron rod 204 to extend, and the brake disc 302 and the bushing 301 sleeved on the output shaft of the servo motor body 1 brake the output shaft of the servo motor body 1. After the electromagnetic coil 205 is energized, the iron inner tube 202 generates magnetism, attracting the extended iron rod 204 into the iron inner tube 202 so that it will not affect the rotation of the output shaft of the servo motor body 1.

[0024] For example, such as Figure 5 As shown, the present invention also includes a keyway 305 provided on the top of the connecting rod 303.

[0025] When in use, the keyway 305 makes it convenient for personnel to use a flat key to fit the external load device onto the outside of the connecting rod 303.

[0026] For example, such as Figure 3 , Figure 5 As shown, the present invention also includes a locking tooth 206 at one end of the iron rod 204, and a circular tooth groove 304 corresponding to the locking tooth 206 is opened on the side of the brake disc 302 near the servo motor body 1.

[0027] When in use, the iron rod 204 extends so that the locking teeth 206 at one end are inserted into the circular tooth groove 304 to brake the brake disc 302.

[0028] In use, personnel use bolts to fix the telescopic component 2 to the top of the servo motor body 1 through the support base 4, use a flat key to put the bushing 301 on the output shaft of the servo motor body 1, use a flat key to put the external load device on the outside of the connecting rod 303 through the keyway 305, and use a power cord to connect the electromagnetic coil 205 to the external intelligent control device.

[0029] When the servo motor body 1 is working, it supplies power to the electromagnetic coil 205. After the electromagnetic coil 205 is energized, the iron inner tube 202 generates magnetism, attracting the iron rod 204 into the iron inner tube 202 so that it will not affect the rotation of the output shaft of the servo motor body 1.

[0030] When the servo motor body 1 stops, the power supply to the electromagnetic coil 205 is disconnected, and the compression spring 203 pushes the iron inner tube 202 to extend, so that the retaining tooth 206 at one end of the iron inner tube 202 is inserted into the circular tooth groove 304 on one side of the brake disc 302. The retaining tooth 206 meshes with the iron column rod 204 to brake the brake disc 302, thereby braking the output shaft of the servo motor body 1 by means of the bushing 301.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
