Description

Technical Field

[0001] This invention belongs to the field of cold chain electrical appliances with self-resetting function, and specifically relates to a door self-resetting function testing device. Background Technology

[0002] Currently, cold chain appliance doors (vertical freezers, refrigerators, etc.) are designed with a self-resetting function to facilitate user operation, improve door sealing, and achieve energy savings. As a functional component, it needs to ensure performance stability and a lifespan that meets the product's lifecycle requirements. During the new product development phase, thorough verification and testing are necessary. With a typical product lifecycle of 5-10 years, the self-resetting function must withstand over 100,000 cycles. This results in a lengthy testing cycle. However, existing testing methods have three major drawbacks:

[0003] (1) The testing cycle is long; manual testing of 100,000 times requires more than 20 days of continuous operation.

[0004] (2) Data is missing, and key parameters such as torque decay and angle deviation cannot be recorded in real time;

[0005] (3) Installation error affects the door closer shaft coaxiality deviation, which leads to abnormal wear and reduces the accuracy of the test. Summary of the Invention

[0006] The purpose of this invention is to provide a door self-reset function testing device, which solves the technical problem of how to test cold chain electrical door bodies with short cycle and high accuracy. It can set the test frequency and number of tests according to the characteristics of the door body, and automatically start and stop the machine, which is convenient and fast, greatly improving the testing efficiency. It can provide effective basic data for new product development, assist in demonstration and analysis, shorten the development cycle, and improve product reliability.

The push wheel 8.1 is in contact with the outer side of the door body 18 and exerts an initial pushing force on the hovering door closer 18.1 after the door body 18 is opened by 90°. The push wheel 8.1 solves the test problem of the hovering door body 18.

[0056] The detection assembly comprises a laser collimator 13 mounted on the upper fixing seat 11 and the lower fixing seat 12, a torsion sensor 15 fixed on the upper fixing seat 11, an encoder 16 connected with the rotating shaft of the torsion sensor 15, and a linkage frame 17 connected with the door body 18. The torsion sensor 15 is connected with an alarm lamp 19 fixed on the equipment frame 3 and connected with a control cabinet 20 through a wire harness.

[0057] When the door body 18 is installed, the coaxiality deviation of the upper and lower door closers 18.1 will accelerate the wear of the rotating sleeve of the door closer 18.1, and then affect the service life of the door closer 18.1. The laser collimator 13 is used for calibrating the coaxiality of the upper fixing seat 11 and the lower fixing seat 12.

[0061] In actual work, the door body 18 drives the door closer 18.1 to rotate, the door rotating shaft 18.7 and the connecting square shaft 18.2 are coaxial, at this time, the connecting square shaft 18.2 is limited on the upper fixed seat 11 or the lower fixed seat 12, the door rotating shaft 18.7 and the connecting square shaft 18.2 do not rotate, and the lower wedge-shaped column 18.3 also does not move, but the shell cylinder rotates, thereby driving the upper wedge-shaped column 18.4 to rotate, and the upper wedge-shaped column 18.4 rotates and moves upward to extrude the spring 18.6; when the door body 18 needs to be reset, the upper wedge-shaped block 18.4 moves downward under the action of the spring 18.6 and contacts the lower wedge-shaped block 18.3, and the above is repeated.

[0062] The door body 18 is connected with the flexible connecting piece 10 and can be reset under the driving of the driving structure, but cannot move synchronously with the door body 18, but under the action of the spring 18.6, the door body 18 can be reset synchronously and immediately.

[0063] The driving structure comprises a servo motor 5 and a speed reducer 6 connected with the servo motor 5, the speed reducer 6 is connected with a transmission shaft 7 through a standard part key, and the speed reducer 6 is fixed on a rack.

[0065] The rack comprises a base 1, a device frame 3 fixed above the base 1, a form wheel 2 fixed below the base 1, a limiting vertical beam 4 and an upper cross beam 22 fixed on the device frame 3.

[0067] In actual work, the door closer 18.1 shaft of the door body 18 is fixed on the upper / lower fixed seat 12, the laser calibration coaxiality is performed, the flexible connecting piece 10 links the door body 18 and the swing arm 8, parameters are set, the frequency is 5 times / minute, the number of times is 100,000 times, and the door opening angle is 90°; the servo system drives the door body 18 to open and close cyclically, and the torque sensor 15 feeds back data in real time; when the set number of times or the torque is abnormal, the machine is automatically stopped and alarm information is pushed.

[0068] The specific working process of the application is as follows:

[0069] The upper fixed seat 11 and the lower fixed seat 12 are fixed on the device frame 3 and the upper cross beam 22.

[0070] Fix the door body 18 on the upper fixed seat 11 and the lower fixed seat 12, and adjust the height of the upper cross beam 22 according to the height of the door body 18. Make the connecting square shaft 18.2 of the door closer 18.1 pass through the square hole of the upper fixed seat 11 and the lower fixed seat 12 and expose 5mm.

[0071] Open the laser collimator 13, adjust the upper fixed seat 11, move left and right, and calibrate the concentricity of the axial hole of the upper and lower fixed seats 12 through the laser collimator 13 to ensure that it is within the tolerance range.

[0072] Connect the door body 18 and the swing arm 8 through the flexible connecting piece 10.

[0074] Then press the start and stop key, the alarm light 19 is lit and the buzzer beeps three times, and the machine is started; the internal preset control program of the touch screen 14.1 calculates the running data of the servo motor 5 according to the input running frequency, opening angle and other parameters, and transmits it to the servo driver 21 to drive the servo motor 5 to run; the servo motor 5 drives the transmission shaft 7 through the speed reducer 6, and rotates according to the input rotation direction; the transmission shaft 7 rotates, drives the swing arm 8 to rotate, and further drives the door body 18 to rotate.

[0075] The door body 18 rotates, drives the rotating shaft of the torsion sensor 15 through the linkage frame 17, and further outputs the torsion value of the torsion sensor 15, which is calculated through a preset equation to obtain the torsion value of the door body 18 reset; since the torsion sensor 15 is connected with the encoder 16, it can output the rotation angle of the door body 18. When the door body 18 rotates 90° clockwise, it is recorded as opening the door once. At the same time, the servo driver 21 drives the motor to reverse, and then rotates 90° counterclockwise, which is recorded as closing the door once.

[0076] For the door closer 18.1 with hovering function, after opening the door 90 degrees, the door body 18 cannot automatically return, and the door body 18 is initially moved by the boost wheel 8.1; the opening and closing times of the door body 18 are displayed on the touch screen 14.1 interface setting position.

[0077] When the opening and closing times of the door body 18 reach the preset number, the buzzer emits a beeping sound for early warning, and the display screen cross section displays a prompt;

[0078] Input the theoretical torsion value A in the program, when the detected torsion value is within the range of 15%, it is considered normal, when it is out of range, it is considered that the self-reset function is abnormal, the buzzer emits a beeping sound for early warning, and the display screen cross section displays a prompt;
