Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0018] Refer to Figure 1 , an electric actuator detection system according to an embodiment of the present invention includes a load adding device, a detection device, and a display (not shown in the figure).

[0019] Among them, the load adding device includes an operation console and a first loading mechanism provided on the operation console; the first loading mechanism includes a first transmission shaft rotatably provided on the operation console, an angle detection component is provided on the first transmission shaft, a first connecting member is provided at the first end of the first transmission shaft and can be connected to the rotary output shaft of the electric actuator 1, a turntable is fixedly sleeved at the second end, and first load members with adjustable load amounts can be hung on both sides of the turntable.

[0020] The detection device includes a power supply, a motor detection circuit, and a clutch detection circuit; the motor detection circuit includes a first connection port F and a second connection port G that can be connected to the input end of the motor 2 of the electric steering gear 1. The first connection port F and the second connection port G are respectively connected to both ends of the power supply through a first switch S1. A voltmeter V is connected to both ends of the power supply, and a first ammeter A1 is connected between the power supply and the first switch. The clutch detection circuit includes a third connection port A and a fourth connection port B that can be connected to the input end of the electromagnetic clutch 3 of the electric steering gear 1. The third connection port and the fourth connection port are respectively connected to both ends of the power supply, and a second switch S2 and a second ammeter A2 are also connected between the power supply and the third connection port and the fourth connection port.

[0021] The display is respectively communicatively connected to the voltmeter V, the first ammeter A1, the second ammeter A2, and the angle detection component, and receives and displays the voltage data detected by the voltmeter V, the current data detected by the first ammeter A1 and the second ammeter A2, and the angle data detected by the angle detection component.

[0022] According to an embodiment of the present invention, in the electric steering gear detection system, the load adding device is used to provide a load for the electric steering gear 1, and the detection device is used to detect the load performance, motor performance, electromagnetic clutch performance, etc. of the electric steering gear.

[0023] Optionally, in the load adding device, the first transmission shaft is a rotary transmission shaft that matches the rotary output shaft of the electric steering gear, and can be rotatably arranged on the operating table through a plurality of fixed bases. Specifically, a plurality of fixed bases are fixedly arranged on the operating table, and the first transmission shaft passes through the plurality of fixed bases and can rotate in the plurality of fixed bases. In addition, a first mounting seat is arranged on the operating table for mounting the electric steering gear with a rotary output shaft, and specifically can be arranged at a position corresponding to the first connecting member. After the electric steering gear is mounted on the first mounting seat, it is convenient for the first connecting member to be drivingly connected to the output shaft of the electric steering gear. After the first end of the first transmission shaft is connected to the rotary output shaft of the electric steering gear through a first connecting member (such as a coupling), the first transmission shaft can rotate driven by the output shaft and drive the turntable at the second end to rotate. The angle detection component is used to detect the rotation angle of the first transmission shaft, which is equivalent to the rotation angle of the rotary output shaft of the electric steering gear.

[0024] Here, on either side of the turntable (one of the two sides of the turntable far from the first transmission shaft), a first load member can be hung to provide a load for the output shaft of the electric steering gear, and the load of the first load member can be adjusted according to the required load amount. The load torque of the first load member hung on one side of the turntable on the first transmission shaft can be calculated based on the weight of the first load member and the diameter of the turntable. When performing no-load detection on the electric steering gear, the first load member can be removed from the turntable. For example, hooks are provided on both sides of the turntable, and the first load member can be located under the operating table and hung on the hook through a steel wire passing through the operating table.

[0025] In the detection device, the voltage input terminal of the motor 2 of the electric steering gear 1 can be connected through the first connection port F and the second connection port G, and the motor 2 of the electric steering gear 1 is connected to the detection device. The power supply AS1 is used to provide an input voltage for the motor 2, so that the working characteristics of the motor 2 can be detected through the motor detection circuit. The first switch S1 is used to control the on and off of the motor detection circuit; the voltmeter V is used to detect the voltage provided by the power supply AS1, that is, the voltage applied across the motor 2; the first ammeter A1 is used to detect the current in the motor detection circuit, which is equivalent to the working current of the motor 2. In addition, a first indicator light DS1 can be connected to both ends of the power supply to indicate whether the power supply is in a working state.

[0026] Furthermore, the first switch S1 includes two on states. The first connection port F and the second connection port G can be connected to the positive and negative poles of the power supply respectively through the first on state, and the first connection port F and the second connection port G can be connected to the negative and positive poles of the power supply respectively through the second on state. That is to say, the first switch S1 is used to convert the polarity of the input voltage applied across the motor 2, and the polarity of the input voltage applied across the load electrode can be controlled by converting the on state of the first switch, so as to control the forward and reverse rotation of the motor 2.

[0027] Also, the electromagnetic clutch 3 of the electric steering gear 1 can be connected to the detection device by connecting the third connection port A and the fourth connection port B to the voltage input terminal of the electromagnetic clutch 3. The power supply AS1 is used to provide an input voltage for the electromagnetic clutch 3, so that the working characteristics of the electromagnetic clutch 3 can be detected through the clutch detection circuit. The second switch S2 is used to control the on and off of the clutch detection circuit, and the second ammeter A2 is used to detect the current in the clutch detection circuit, which is equivalent to the working current of the electromagnetic clutch 3.

[0028] In an optional embodiment, the detection device further includes a micro switch detection circuit, which includes a fifth connection port D, a sixth connection port C and a seventh connection port L, which can be respectively connected to the fixed end, the normally closed contact and the normally open contact of the micro switch 4 of the electric servo 1. Among them, the fifth connection port D is connected to the positive pole of the power supply, and the sixth connection port C and the seventh connection port L are respectively connected in series with the second indicator light DS2 and the third indicator light DS3 and then connected to the negative pole of the power supply.

[0029] By connecting the fifth connection port D, the sixth connection port C and the seventh connection port L to the fixed end of the micro switch 4, the normally closed contact N C The micro switch 4 is connected to the normally open contact N0, and the micro switch 4 can be connected to the detection circuit. The power supply AS1 is used to provide an input voltage to the micro switch 4, so that the working characteristics of the micro switch 4 can be detected by the detection circuit of the micro switch 4. According to the lighting state and changes of the second indicator light DS2 and the third indicator light DS3, it can be judged whether the micro switch 4 is actuated and the closed state of the micro switch 4 can be judged.

[0030] In an optional embodiment, the load-adding device further includes a second loading mechanism, and the second loading mechanism includes a displacement detection component, and the displacement detection component has a retractable second transmission shaft. The second transmission shaft is a rotating transmission shaft that matches the telescopic output shaft of the electric servo, and a second connecting member is provided at its telescopic end, and the second connecting member can be connected to the telescopic output shaft of the electric servo by transmission; a load bracket is also provided at the telescopic end of the second transmission shaft. Pulley blocks are respectively provided on both sides of the operating table corresponding to the telescopic direction of the second transmission shaft, and both pulley blocks are provided with a second load member connected to the load bracket through a connecting wire (such as a steel wire), and the load amount of the second load member is adjustable. It is equivalent to the second load member being hung on the load bracket through a connecting thin wire, which can provide a load for the telescopic output shaft.

[0031] Furthermore, a second mounting seat is also provided on the operating table. The second mounting seat is provided at a position corresponding to the installation position of the displacement detection assembly, and is located in the telescopic direction of the second transmission shaft, and is used to install an electric servo with a telescopic output shaft. Both pulley groups may include two pulleys. The two pulleys of the pulley group close to the second mounting seat are respectively provided on both sides of the telescopic output shaft of the electric servo 1, and the two pulleys of the other pulley group are respectively provided on both sides of the displacement detection assembly, so as to avoid interference between the connecting wire on the pulley group and the telescopic output shaft and the second transmission shaft. The second load member can be hung on both pulley groups by connecting thin wires to provide a load for the telescopic action of the telescopic output shaft of the electric servo.

[0032] By installing an electric steering gear with a telescopic output shaft on the second mounting base and connecting the second transmission shaft to the telescopic output shaft through a second connecting member, the second transmission shaft can generate displacement when the output shaft expands and contracts. The displacement of the second transmission shaft detected by the displacement detection component is equivalent to the displacement of the telescopic output shaft of the electric steering gear. The display is also communicatively connected to the displacement detection component to receive and display the displacement data detected by the displacement detection component.

[0033] In practical applications, the electric steering gear detection system of the embodiment of the present invention may further include other components to realize the actual installation and application of the system. For example, the electric steering gear detection system further includes connection cables for connecting the connection ports of the system to various components on the electric steering gear.

[0034] The electric steering gear detection system of the embodiment of the present invention can be rotationally connected to the output shaft of the electric steering gear through a load adding device. A turntable for hanging a load member can be provided on the rotational transmission shaft to add a load to the rotational output shaft of the steering gear, or a pulley and a bracket for hanging a load member can be provided on the telescopic transmission shaft to add a load to the telescopic output shaft of the steering gear. Furthermore, the load operation state of the electric steering gear can be simulated, and the performance test of the electric steering gear can be realized by detecting data such as the rotation angle or telescopic displacement, current, and voltage of the transmission shaft. Thus, it can be detected whether various performances of the electric steering gear are qualified, which is convenient for fault analysis and component maintenance of the electric steering gear. The detection accuracy meets the test requirements, which helps to improve the detection and maintenance efficiency of the electric steering gear; moreover, the electric steering gear detection system has simple equipment and reliable performance.

[0035] It should be noted that according to the needs of implementation, each component described in the embodiment of the present invention can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiment of the present invention.

[0036] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
