Description

Technical Field

[0001] The utility model relates to the technical field of servo motors, in particular to a power supply connection mechanism for servo motors. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device that can convert voltage signals into torque and speed to drive the control object, and has the characteristics of high-precision control of speed and position. Its working principle is that its rotor speed is controlled by the input signal and can respond quickly. In the automatic control system, the servo motor is used as an actuator, with characteristics such as small electromechanical time constant, high linearity, and starting voltage. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is widely used in automation equipment that requires precise positioning, high-speed movement, high torque output, high stability, low noise, etc., such as CNC machine tools, semiconductor manufacturing, imaging equipment, packaging equipment, and robotics.

[0003] The core components of the servo motor mainly include the stator, rotor, winding, encoder and cooling fan. Traditional servo motors mostly use a shell with a mounting cavity to install these components, and then the electrical connection wires of each component are led to the outside for external wiring.

[0004] However, if you want to fix and connect so many components in the same installation cavity, due to space limitations, it is easy to cause confusion in the wiring harnesses of the components. Not only is the wiring troublesome, but the assembly efficiency is also low. When power is turned on, it will also cause current interference to the components, thus affecting the use effect.

[0005] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to overcome the problems of the above-mentioned prior art and provide a power supply wiring mechanism for a servo motor to solve the technical problem that the traditional servo motor adopts a single shell with a mounting cavity, which is limited by space and easily causes confusion of the wiring harnesses of various components, not only cumbersome wiring, but also low assembly efficiency, and causes current interference to the components when power is turned on, thereby affecting the use effect.

[0007] The above objectives are achieved through the following technical solutions:

[0008] A power supply wiring mechanism for a servo motor comprises a first shell, and a second shell that can be sleeved on the first shell; the front end and the rear end of the first shell are respectively provided with a front end cover and a rear end cover, and the front end cover, the first shell and the rear end cover are connected to each other to form a first installation cavity; the second shell comprises a sleeve portion and a shell portion, and the rear end of the second shell is provided with a fan cover, and the fan cover, the shell portion and the rear end cover form a second installation cavity; a junction box with a third installation cavity is provided on the outer wall of the second shell; a first wire hole is provided on the side wall of the first shell, a second wire hole is provided on the side wall of the second shell, and a third wire hole is provided on the bottom wall of the junction box, and the first wire hole, the second wire hole and the third wire hole can connect the first installation cavity with the third installation cavity; the rear end cover is provided with a threading hole that can connect the first installation cavity with the second installation cavity.

[0009] Furthermore, a terminal guide rail and a three-phase terminal that can slide along the terminal guide rail are arranged in the third installation cavity.

[0010] Furthermore, the junction box includes a box body connected to the outer wall of the second shell, and an upper cover corresponding thereto.

[0011] Furthermore, a plurality of wiring guide sleeves are arranged on the side of the box body so that the external wiring harness can enter the third cavity.

[0012] Furthermore, the second wire hole is located at the sleeve portion, and a lead sleeve capable of connecting the first wire hole and the third wire hole is provided at the second wire hole.

[0013] Furthermore, the centers of the first wire hole, the second wire hole and the third wire hole are coaxial.

[0014] Further, the first wire hole and the second wire hole are both located on the top of the first shell and the second shell.

[0015] Furthermore, the threading hole is arranged at a position eccentric to the center of the rear end cover.

[0016] Furthermore, the first shell and the second shell are both made of metal.

[0017] Furthermore, the junction box is made of hard material.

[0018] The utility model provides a power supply wiring mechanism for a servo motor, which is not only simple in structure, but also can gather the wiring harnesses of the first installation cavity and the second installation cavity into the wiring box at the top, thereby making it more convenient to unify the wiring operation with the outside. Compared with the prior art, it can effectively arrange and pull the wiring harnesses of each component, and can also avoid the problem of current interference during operation.
