Description

Technical Field

[0001] This utility model relates to the technical field of actuator testing devices, specifically to actuator testing devices. Background Technology

[0002] A valve actuator is a device that automatically controls the opening and closing of a valve based on control signals from a controller, thereby controlling the flow rate of a fluid medium. It is an essential component of an automatic control system. Existing valve actuators typically consist of two parts: a valve and an actuator, which are fixedly connected together. The valve contains a valve core, and the actuator contains a drive assembly. The output shaft of the drive assembly is connected to the valve core for transmission, thus driving the valve core to open and close.

[0003] Before leaving the factory, actuators need to be tested by specialized equipment to determine if they are functioning properly. Conventional testing equipment requires first connecting the charging port of the product under test (valve actuator) to the test module, then starting the control button of the test module to perform the test, and then replacing it with the next product under test after the test is completed. Because the testing process requires waiting, and the equipment can only test one product at a time, the testing efficiency is very low. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an actuator testing device that is convenient and efficient for testing.

[0005] The technical solution of this utility model is to provide an actuator testing device with the following structure: including a housing and a circuit board disposed inside the housing, the circuit board having two rows of test module groups, each test module group including several test modules spaced apart along the length of the circuit board; the two side walls of the housing having plug interfaces corresponding to the test modules, the plug interfaces being electrically connected to the corresponding test modules; the bottom of the housing being connected to a heat dissipation component for heat dissipation of the circuit board.

[0006] After adopting the above structure, the actuator testing device of this utility model has the following advantages compared with the prior art:

[0007] This invention sets up multiple test modules on the circuit board, which can connect multiple products to be tested at the same time and then perform tests simultaneously, saving excessively long test waiting time and thus improving test efficiency. Since multiple test modules are connected on the circuit board, a large current will pass through during testing, which can easily cause the circuit board to overheat. Therefore, a heat dissipation component is connected to the bottom of the housing to dissipate heat from the circuit board in a timely manner.

[0008] Preferably, one end of the housing is provided with a control button, which is electrically connected to the circuit board and used to control the start and stop of the test module. Multiple control buttons are available, and test parameters can also be set, as well as the start and stop of the heat dissipation components.

[0009] Preferably, the housing is equipped with a display screen, which is electrically connected to the circuit board and used to display test data. The display screen can simultaneously display test data from multiple test modules, facilitating user observation.

[0010] Preferably, the heat dissipation assembly includes a cooling fan and a heat sink, with the cooling fan positioned on one side of the heat sink to blow air onto it. The cooling fan can accelerate heat dissipation from the heat sink and improve heat dissipation efficiency.

[0011] Preferably, the heat sink includes a cylindrical portion and plate-shaped portions; the cylindrical portion is rectangular in shape, with its upper end face extending into the housing and abutting against the lower end face of the circuit board; there are multiple plate-shaped portions, spaced apart along the width direction of the inner cavity of the cylindrical portion; both ends of the cylindrical portion are open, and the cooling fan is located at one end of the cylindrical portion to blow air to the other end. By configuring the heat sink into two parts, the upper end face of the cylindrical portion has a larger contact surface, which is beneficial for the circuit board to transfer heat to the cylindrical portion. Then, the cooling fan blows air from one side, and the cool air passes through the gaps between the plate-shaped portions, which can quickly remove the heat transferred from the cylindrical portion, thereby improving the heat dissipation efficiency.

[0012] Preferably, the bottom of the housing is provided with support feet at both ends to separate the lower end of the heat dissipation component from the desktop, thereby improving the heat dissipation efficiency of the heat dissipation component. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model. At the same time, the terms "first", "second", etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship.

[0022] like Figures 1-5 As shown, this utility model discloses an actuator testing device: including a housing 1 and a circuit board 2 disposed inside the housing 1. The circuit board 2 is provided with two rows of test module groups, each test module group including several test modules 3 distributed at intervals along the length direction of the circuit board 2; the two side walls of the housing 1 are provided with plug interfaces 11 corresponding to the test modules 3 one by one, and the plug interfaces 11 are electrically connected to the corresponding test modules 3; the bottom of the housing 1 is connected to a heat dissipation component 4 for heat dissipation of the circuit board 2.

[0023] This invention sets multiple test modules 3 on the circuit board 2, which can connect multiple products to be tested at one time and then perform tests simultaneously, saving excessively long test waiting time and thus improving test efficiency. Since multiple test modules 3 are connected on the circuit board 2, a large current will pass through during testing, which can easily cause the circuit board 2 to overheat. Therefore, a heat dissipation component 4 is connected to the bottom of the housing 1 to dissipate heat from the circuit board 2 in a timely manner.

[0024] One end of the housing 1 is equipped with a control button 5, which is electrically connected to the circuit board 2 and is used to control the start and stop of the test module 3. There are multiple control buttons 5, which can also be used to set test parameters and control the start and stop of the heat dissipation component 4.

[0025] The housing 1 is equipped with a display screen 6, which is electrically connected to the circuit board 2. It can display the test data of multiple test modules 3 at the same time, making it convenient for users to observe the test results.

[0026] Preferably, the heat dissipation assembly 4 includes a cooling fan 41 and a heat sink 42. The cooling fan 41 is disposed on one side of the heat sink 42 and is used to blow air onto the heat sink 42. The cooling fan 41 can accelerate the heat dissipation of the heat sink 42 and improve the heat dissipation efficiency.

[0027] The heat sink 42 includes a cylindrical portion 421 and a sheet portion 422. The cylindrical portion 421 is rectangular and its upper end extends into the housing 1 and abuts against the lower end of the circuit board 2. There are multiple sheet portions 422, which are spaced apart along the width direction of the inner cavity of the cylindrical portion 421. Both ends of the cylindrical portion 421 are open. A cooling fan 41 is provided at one end of the cylindrical portion 421 for blowing air to the other end.

[0028] In this invention, the heat sink 42 is configured as two parts: a cylindrical part 421 and a sheet part 422. The upper end surface of the cylindrical part 421 has a larger contact surface, which is beneficial for the circuit board 2 to transfer heat to the cylindrical part 421. Then, the cooling fan 41 blows air from one side. The cold air passes through the gap between the sheet parts 422 and can quickly remove the heat transferred from the cylindrical part 421, thereby improving the heat dissipation efficiency.

[0029] A power interface is also provided on one side of the housing 1 for connecting to an external power source. Support feet 12 are also provided at both ends of the bottom of the housing 1 to separate the lower end of the heat dissipation component 4 from the desktop, thereby improving the heat dissipation efficiency of the heat dissipation component 4.

[0030] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
