Description

Modular servo housing and servo using its chassis

This creation is related to the motor defined by International Classification No. H02K, specifically the structural improvement of a servo casing.

Servo machines are often used as power sources for providing specific functions in various automation devices. They are mainly used for parts that require accurate angular position control. Therefore, servo machines are not only widely used in remote control model products, but also the key in the robot industry. One of the components.

The structure of a conventional servo machine usually includes components such as a motor, a power output shaft, and a reduction gear set, wherein the reduction gear set is rotatable by the motor and rotates the power output shaft. However, the internal space of the traditional servo casing is limited. In order to use the space inside the casing more effectively, the servo can be equipped with a larger rotor or stator under the same volume. Some servos use a shellless motor. Designed to increase the output power of the servo.

However, the caseless motor is not assembled in advance as a general cased motor, but is assembled at the same time as the servo is assembled, making the assembly work of the entire servo more complicated. In this way, not only will the production capacity be reduced, but the disassembly and assembly of the servo machine will become more difficult in the subsequent maintenance work.

In view of this, the main purpose of this creation is to provide a servo machine that can be added Convenience when assembling and disassembling the servo.

In order to achieve the above object, the present invention provides a modular servo casing including a first cylinder and a second cylinder which are hollow and have at least one opening, and the first cylinder is outside. The surface is provided with at least one first fitting portion, and the outer surface of the second cylinder is provided with at least one second fitting portion for detachably fitting the at least one first fitting portion.

The present invention further provides a servo machine including the above-described modular servo casing, and a lower cover, a motor and a circuit board. The lower cover is disposed at a bottom end of the first cylinder and the second cylinder. The motor is an opening disposed in the second cylinder and having a plurality of terminals extending from the second cylinder. The circuit board is disposed between the first cylinder, the second cylinder and the lower cover, and the circuit board is provided with an electrical connection structure for electrically connecting the terminals.

Thereby, the components inside the servo machine can be assembled in the first cylinder body or the second cylinder body first, and then the first and second cylinder bodies are integrally assembled by the above-mentioned fitting portion, so assembly is not only convenient. The components inside the first and second cylinders can be simultaneously synchronized to improve the overall assembly efficiency and productivity, and also facilitate the disassembly process during subsequent maintenance operations.

In order to better understand the characteristics of the modularized servo casing of the present creation, the present invention provides a preferred embodiment and is described below with reference to the drawings, please refer to Figures 1 to 4. For convenience of explanation, the following description is based on the upward direction of the power output shaft 40 of the servo machine 1 as a reference.

Referring first to FIGS. 1 to 2, the casing 10 of the server includes an upper cover 11, a lower cover 14, and a first cylinder 12 and a second cylinder 13 connected between the upper cover 11 and the lower cover 14. The upper cover 11 defines an opening 111 for a power output shaft 40 of the servo machine 1 to extend. A circuit board 50 is disposed between the lower cover 14 and the first cylinder 12 and the second cylinder 13 for supplying electric power to the components inside the servo 1. A gear set 30 is disposed between the upper cover 11 and the first cylinder 12 and the second cylinder 13. The gear set 30 can be received by a motor 20 (in this embodiment, a shellless motor). The driving of the power output shaft 40 is not the focus of the present invention due to the operation of the motor 20, the gear set 30, and the power output shaft 40, and will not be described in detail herein.

Referring to FIGS. 2 and 3, the inside of the first cylinder 12 and the second cylinder 13 are hollow and each has an assembly chamber 121, 131, and the bottoms of the first and second cylinders 12, 13 The ends are open with openings 122, 132 communicating with the assembly chambers 121, 131, so that the angle detector 60 and the motor 20 of the servo 1 can be respectively mounted to the assembly chambers 121, 131 of the first and second cylinders 12, 13. in. The first and second cylinders 12, 13 each have a corresponding outer surface, and are respectively provided with a set of first fitting portions 123 and a second fitting portion 133. In this embodiment, the first fitting portion 123 The two sliders are disposed in parallel with each other, and for structural stability, the cross sections of the two sliders are designed in a T-shape, and the two sliders extend from the top end of the first cylinder 12 toward the bottom end. The second fitting portion 133 is formed by recessing two sliding rails from the outer surface of the second cylindrical body 13. The two sliding rails are spaced apart from each other by two sliders, and the cross sections of the two sliding rails are also T-shaped. Having the first and second cylinders 12, 13 The two slide rails are combined with the two sliders to be integrated.

In addition, the top end of the first cylinder 12 is provided with a mounting seat 124 for mounting the power output shaft 40. The power output shaft 40 is detected by the opening 125 in the center of the mounting seat 124 and the angle disposed inside the first cylinder 12. The units 60 are connected to detect the angle of rotation of the power output shaft 40. The top end of the second cylinder 13 defines an upper opening 134, and the upper opening 134, the assembly chamber 131, and the lower opening 132 are all in communication. In the present embodiment, the motor 20 is mounted to the second cylinder 13, so that the rotating shaft 22 of the motor 20 can be coupled to the gear train 30 by the upper opening 134. Since the mount 124 is only for the convenience of mounting the power take-off shaft 40, the mount 124 is not a necessary component.
