Description

Technical Field

[0001] The utility model relates to the technical field of brakes, and more specifically, to an integrated coded brake. Background Art

[0002] An encoder is a device that converts angular displacement or linear displacement into an electrical signal. The former is called a code disk, and the latter is called a code scale. The converted electrical signal can be used as a feedback signal of the actual position and state of the device at the control end to timely correct the output of the drive end and improve the operation accuracy of the device. And the speed of a motor, a rotating shaft, etc. can be measured through an encoder. Usually, the encoder and the brake are two separate components installed on the tail end of the motor shaft in sequence to control the rotation speed of the motor shaft. When the installation space inside the device is limited, this installation method is relatively large in volume and occupies a larger installation space, making it difficult to apply to this scenario. Therefore, an integrated coded brake is designed, which requires less axial space for installation. Summary of the Utility Model

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Generally, the components of the embodiments of the present utility model described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0018] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0019] The following is further described with reference to specific embodiments. Refer to Figure 1 - Figure 2As shown in the figure, this embodiment is an integrated coded brake, which includes a stator 1, an armature 2, a rotor 3, and a flange 4 that are axially connected in sequence. It includes a PCB board 5, which is arranged close to the flange 4 and fixedly connected thereto. A code disk 7 and a sleeve 6, the sleeve 6 is respectively connected to the rotor 3 and the code disk 7, so that the sleeve 6 and the rotor 3 rotate synchronously with the motor shaft. Specifically, both the encoder and the brake need to be connected to the motor shaft, and in this utility model, the extended sleeve 6 is set to be connected to the motor shaft for synchronous rotation, and the sleeve 6 is also connected to the rotor 3 of the brake and at the same time to the code disk 7 of the encoder. The code disk 7 reflects the rotational speed of the motor shaft by detecting the rotational speed of the sleeve 6, and the braking of the rotor 3 by the armature 2 can also be transmitted to the motor shaft through the sleeve 6. Through the above structure, the integration of the encoder and the brake is realized, thereby shortening the axial dimension of the two and increasing the upper limit of the application and installation of this brake.

[0020] Refer to Figure 1 As shown in the figure, at least one limiting cylinder 8 is abutted between the PCB board 5 and the flange 4 in this embodiment, and a connecting screw 9 is connected between the PCB board 5 and the flange 4, and the connecting screw 9 passes through the limiting cylinder 8. Specifically, the PCB board 5 of the encoder is connected through the connecting screw 9, and the limiting cylinder 8 is set to isolate a receiving space between the flange 4 to prevent the surface of the PCB board 5 from contacting and squeezing the electronic components.

[0021] As Figure 1 shown in the figure, the code disk 7, the sleeve 6, and the PCB board 5 are coaxially arranged, and the code disk 7 and the rotor 3 also coincide with the axis.

[0022] As Figure 2 shown in the figure, a stepped opening 61 adapted to the code disk 7 is provided at one end of the sleeve 6. The code disk 7 is connected to the sleeve 6 and rotates synchronously with the motor shaft, and the depth of the stepped opening 61 is the same as the thickness of the code disk 7. The inner hole of the code disk 7 just fits into it, so that there will be no large displacement in the radial direction.

[0023] In order for the rotor 3 and the sleeve 6 to have a longer contact length, the rotor 3 is provided with a boss structure, which passes through the central hole of the flange 4, thereby helping to transmit the torque between the rotor 3 and the sleeve 6 and improving its service strength.

[0024] As Figure 1 shown in the figure, 45° chamfers are provided at both ends of the inner hole of the sleeve 6, which helps the motor shaft to penetrate into the sleeve 6 during installation.

[0025] It is worth noting that the sleeve 6 and the rotor 3 are connected by splines, so that when the armature 2 contacts and brakes the rotor 3, the rotor 3 can transmit the torque to the sleeve 6 more evenly.

[0026] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
