Description

Technical Field

[0001] The present invention relates to the field of switch characteristic detection, and specifically refers to an on-line test device for switch mechanical characteristics. Background Art

[0002] A switch is an important component in the power system, which can disconnect or connect both ends of a circuit and perform the function of energizing or de-energizing the corresponding electrical appliance. The switch includes multiple mechanical characteristics, such as pressing force, switch stroke, vibration and shock resistance, etc. After the switch is produced, it is necessary to detect the mechanical characteristics of the switch.

[0003] Among the mechanical characteristics of the switch, the vibration resistance performance is a key parameter. The application fields of the switch are relatively wide, such as on large mechanical equipment such as work vehicles and ships, or in small electrical appliances such as razors, juicers, and percussion massagers. Due to the different application scenarios of the switch, the frequencies, amplitudes, periods, etc. of the external vibrations it receives are also different. For example, a ship will be subjected to low-frequency and random shaking on the sea, a work vehicle will have low-frequency and large-amplitude vibrations, while a razor, a juicer, a percussion massager, etc. will have high-frequency and small-amplitude vibrations. In the prior art, for the detection of the vibration-resistant mechanical characteristics of the switch, a tremor motor is generally installed on the workbench to generate vibrations for the switch. However, the vibrations, amplitudes, etc. generated by this method are fixed and it is difficult to set according to the application scenario of the switch, so it is impossible to generate vibrations with multiple amplitudes and multiple random situations.

[0004] Designing an on-line test device for switch mechanical characteristics to solve the problems existing in the above prior art is the purpose of the research of the present invention. Summary of the Invention

[0005] Aiming at the problems existing in the above prior art, the present invention provides an on-line test device for switch mechanical characteristics, which can effectively solve at least one of the problems existing in the above prior art.

[0006] The technical solution of the present invention is as follows:

[0007] An on-line test device for switch mechanical characteristics, comprising:

[0008] A frame, including several legs and a test platform supported by the several legs together;

[0009] A tremor mechanism, arranged on the test platform;

[0010] A switch operating mechanism, including a switch fixing seat and a power-on and power-off mechanism for operating the switch on the switch fixing seat;

[0011] Test platform fluctuation adjustment mechanism, the support leg includes an upper support leg and a lower support leg, the test platform fluctuation adjustment mechanism is arranged between the upper support leg and the lower support leg, the test platform fluctuation adjustment mechanism includes an elastic member and an adjustable damping member, the elastic member is supported between the upper support leg and the lower support leg, and the adjustable damping member adjusts the elasticity of the elastic member;

[0012] Vibration adjustment mechanisms, with a number of them arranged on the test platform. The vibration adjustment mechanism includes a containing tank. There are damping particles contained in the containing tank. Different containing tanks have different damping particles. The interior of the containing tank is separated into two vertically separated cavities by a vertically moving partition plate. There are lugs arranged on the outer ring of the partition plate. The partition plate is provided with a controllable opening. The containing tank is driven by a longitudinal driving cylinder. The switch operating mechanism is provided with an installation groove that cooperates with the containing tank. After the containing tank is driven by the longitudinal driving cylinder and inserted into the installation groove, the damping particles in the downward-facing cavity in the containing tank absorb part of the vibration emitted by the tremor mechanism, and the top of the installation groove abuts against the lugs to thus compress the damping particles in the upward-facing cavity in the containing tank.

[0013] Furthermore, the switch operating mechanism includes a sliding seat arranged on the test platform. The sliding seat is driven by a transverse driving cylinder, and the switch fixing seat is arranged on the sliding seat;

[0014] The up and down power mechanism includes a swing rod, which is hinged above the sliding seat. One end of the swing rod is connected by a pressing driving cylinder, and the pressing driving cylinder drives the swing rod to swing to thus operate the switch.

[0015] Furthermore, the adjustable damping member is an airbag. The airbag is in an annular columnar structure. One end of the airbag is fixedly connected to the upper support leg or the lower support leg. The lower support leg is provided with a guide post, and the guide post extends into the inner wall of the airbag. After the airbag is connected to the corresponding inflating member and the inflating member inflates the airbag, the friction force between the inner ring of the airbag and the guide post increases to thus hinder the elastic force of the elastic member.

[0016] Furthermore, a pressure maintaining valve is arranged between the airbag and the inflating member.

[0017] Furthermore, the top of the installation groove is provided with a pressing column. The pressing column is of a hollow structure. A spring is arranged inside the pressing column. The spring protrudes above the pressing column in the non-loaded state. After the containing tank is driven by the longitudinal driving cylinder and inserted into the installation groove, the pressing column abuts against the lugs, and the spring applies an upward movement tendency elastic force to the lugs.

[0018] Furthermore, it includes a rotating cylinder. The rotating cylinder is driven by the longitudinal driving cylinder, and the rotating cylinder drives the containing tank to rotate.

[0019] Furthermore, the partition plate is provided with an opening groove. The controllable opening includes a rotating plate hinged to one side of the opening groove, and the rotating plate is driven by a rotating motor to thus block or open the opening groove.

[0020] Furthermore, the damping particles are spherical particles supported by one or more of the materials of metal, plastic, rubber, glass, and ceramic, and the diameter of the damping particles is 1-5 mm.

[0021] Furthermore, the control method includes:

[0022] S1. Control the controllable opening to close, so that all the damping particles are accommodated in the upward-facing cavity of the accommodation tank body. Control the longitudinal drive cylinder to drive the accommodation tank body to insert into the installation groove and press it tightly. Control the tremor mechanism to vibrate. During the vibration of the tremor mechanism, control the damping of the adjustable damper to gradually increase, so that the switch operating mechanism is subjected to different fluctuations.

[0023] S2. Control the damping of the adjustable damper to reach the maximum. Control the controllable opening to open and let a part of the damping particles fall into the downward-facing cavity of the accommodation tank body. Control the longitudinal drive cylinder to drive the accommodation tank body to insert into the installation groove and press it tightly. After the damping particles absorb a part of the vibration, change the amplitude or frequency of the vibration received by the switch operating mechanism.

[0024] S3. Repeat S2 until all the damping particles fall into the downward-facing cavity of the accommodation tank body to complete the test.

[0025] Therefore, the present invention provides the following effects and / or advantages:

[0026] In this application, the elastic member and the adjustable damper are used to change the support rigidity between the upper leg and the lower leg, thereby changing the fluctuations generated by the low-frequency vibration of the tremor mechanism on the test platform, making the amplitude, range, etc. of the fluctuations adjustable. For the low-frequency vibrations of ships at sea or working vehicles, etc., and to simulate the fluctuations generated by vehicles or ships on the switch under different loads, it can be applied to different scenarios.

[0027] In this application, the upper and lower cavities are separated by a partition plate, and the controllable opening releases particles in stages. The damping intensity is adjusted by the falling amount of the particles, and the particles participating in energy consumption are gradually increased to achieve the rapid switching and superposition of damping characteristics. The high-frequency vibration energy is dissipated through particle collision and friction, and the vibration amplitude transmitted to the switch is gradually reduced to test the performance of the switch under centering vibration.

[0028] In this application, the installation groove cooperates with the hanging ear to press the damping particles above it, so that the damping particles in this area do not participate in the vibration absorption effect, realizing the implementation of this solution. And a upward movement tendency force is applied to the hanging ear through a spring, so as to ensure that the partition plate always keeps squeezing the damping particles above it.

[0029] This application is provided with a rotary cylinder, which can rotate the tank body after a single test, so as to automatically adapt to the next measurement work without manual operation.

[0030] Other features and advantages of the present invention will be set forth in the following description, and in part will be obvious from the description, or may be learned by practice of the present invention. The objectives and other advantages of the present invention are realized and attained by the structure particularly pointed out in the specification and the drawings.

Detailed Description of the Embodiment

[0042] For the convenience of those skilled in the art to understand, the structure of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0043] Reference Figure 1-8, an on-line test device for the mechanical characteristics of a switch, comprising:

[0044] A frame 1, including several legs and a test platform 13 supported by several of the legs;

[0045] A tremor mechanism 2, arranged on the test platform 13;

[0046] A switch operating mechanism 3, including a switch fixing seat 31 and a power-on and power-off mechanism 32 for operating the switch on the switch fixing seat 31;

[0047] In this embodiment, the tremor mechanism 2 and the switch operating mechanism 3 can be directly adopted from the prior art. The tremor mechanism 2 is used to generate vibrations, and the switch operating mechanism 3 is used to perform power-on and power-off operations on the switch. It can be of various types such as a pressing type, a rotary type, or a stroke type, etc. Among them, the pressing type can press the switch to power it on and off, the rotary type can rotate the switch to adjust the opening degree of the switch or power it on and off, and the stroke type can perform an action similar to toggling on the switch to power it on and off.

[0048] A test platform fluctuation adjustment mechanism 4. The legs include an upper leg 11 and a lower leg 12. The test platform fluctuation adjustment mechanism 4 is arranged between the upper leg 11 and the lower leg 12. The test platform fluctuation adjustment mechanism 4 includes an elastic member 41 and an adjustable damping member 42. The elastic member 41 is supported between the upper leg 11 and the lower leg 12, and the adjustable damping member 42 adjusts the elasticity of the elastic member 41;

[0049] In order to adapt to the low-frequency vibrations of ships at sea or work vehicles, etc., this application is achieved through the test platform fluctuation adjustment mechanism 4. The environment where ships or work vehicles are located has certain vibrations or fluctuations, such as the vibrations emitted by engines or the vibrations caused by waves hitting, etc. And when ships or work vehicles are in different load conditions, environments, engine powers, etc., the amplitudes or frequencies of the vibrations received by the switches on them are also different. In order to simulate the vibrations of various random situations with low frequency and different amplitudes and frequencies, this embodiment is implemented by using the elastic member 41 and the adjustable damping member 42. Among them, the elastic member 41 is supported between the upper leg 11 and the lower leg 12, playing a certain supporting role and having a certain buffering effect at the same time. The adjustable damping member 42 adjusts the elasticity of the elastic member 41. It can be understood that when the adjustable damping member 42 reduces the elasticity of the spring 562, the rigid component of the supporting force of the spring 562 on the upper leg 11 and the lower leg 12 increases, thereby changing the natural frequency of the overall structure system composed of components such as the switch operating mechanism 3 and the frame 1, and then changing the vibration of the tremor mechanism 2 on the switch operating mechanism 3, and further simulating the low-frequency fluctuations in various situations.

[0050] The vibration adjustment mechanism 5, with a number of them, is arranged on the test platform 13. The vibration adjustment mechanism 5 includes a containing tank body 51, in which damping particles 52 are contained. The damping particles 52 provided in different containing tank bodies 51 are different. The interior of the containing tank body 51 is divided into two vertically separated cavities by a vertically movable partition plate 53. An ear 54 is arranged on the outer ring of the partition plate 53. The partition plate 53 is provided with a controllable opening 55. The containing tank body 51 is driven by a longitudinal driving cylinder 57. The switch operating mechanism 3 is provided with a mounting groove 56 that cooperates with the containing tank body 51. After the containing tank body 51 is driven by the longitudinal driving cylinder 57 and inserted into the mounting groove 56, the damping particles 52 in the cavity facing downward in the containing tank body 51 absorb a part of the vibration emitted by the tremor mechanism 2, and the top end of the mounting groove 56 abuts against the ear 54 to thus compress the damping particles 52 in the cavity facing upward in the containing tank body 51.

[0051] The vibration adjustment mechanism 5 is also one of the core improvements of this application.

[0052] First, the containing tank body 51 is separated into two upper and lower cavities by the partition plate 53, and the partition plate 53 is provided with a controllable opening 55. Therefore, the controllable opening 55 can be opened or closed, so as to release a part of the damping particles 52 and let them fall into the cavity facing downward. The damping particles 52 below the partition plate 53 have a certain space to move. After the tremor mechanism 2 emits vibration, the movable damping particles 52 collide and rub against each other, etc., so as to absorb a part of the vibration received by the switch operating mechanism 3 and reduce the frequency or amplitude of the vibration emitted by the tremor mechanism 2. By opening or closing the controllable opening 55, the number of movable damping particles 52 below the partition plate 53 can be controlled, so as to change the vibration absorption effect of the vibration adjustment mechanism 5, and finally change the vibration received by the switch operating mechanism 3.

[0053] In addition, the containing tank body 51 is driven by the longitudinal driving cylinder 57 and the partition plate 53 is provided with an ear 54. The ear 54 is arranged on the outer side of the containing tank body 51. Therefore, pushing the ear 54 can push the partition plate 53 to move. After the containing tank body 51 is inserted into the mounting groove 56, the partition plate 53 is pushed upward to thus squeeze the space of the damping particles 52 above the partition plate 53, making it impossible for them to collide or rub against each other, etc. That is to say, the damping particles 52 above the partition plate 53 are squeezed and thus cannot move. At this time, the damping particles 52 in this area do not work and do not affect the vibration.

[0054] By having different damping particles 52 provided in the different accommodating tanks 51, for example, by providing damping particles 52 of different materials or particle sizes in the accommodating tank 51, the absorption frequency, absorption amplitude, absorption rate, etc. of vibration by the damping particles 52 of different materials or particle sizes are different, thereby realizing the vibration control of the switch.

[0055] By changing different damping particles 52 and the number of movable damping particles 52, the absorption effects on vibration are also different, thereby simulating vibrations of various amplitudes and frequencies, and then conducting a comprehensive test on the switch.

[0056] Further, the switch operating mechanism 3 includes a sliding seat 33, the sliding seat 33 is arranged on the test platform 13, the sliding seat 33 is driven by a lateral driving cylinder 34, and the switch fixing seat 31 is arranged on the sliding seat 33;

[0057] The power-on and power-off mechanism 32 includes a swing rod 321, which is hinged above the sliding seat 33, one end of the swing rod 321 is connected by a pressing driving cylinder 322, and the pressing driving cylinder 322 drives the swing rod 321 to swing so as to operate the switch.

[0058] In this embodiment, the sliding seat 33 can slide left and right, thereby driving the switch fixing seat 31 to approach or move away from the power-on and power-off mechanism 32, so that the power-on and power-off mechanism 32 can perform power-on and power-off operations on the switch.

[0059] Further, the adjustable damping member 42 is an airbag, the airbag is of an annular columnar structure, one end of the airbag is fixedly connected to the upper leg 11 or the lower leg 12, the lower leg 12 is provided with a guide post 14, the guide post 14 extends into the inner wall of the airbag, the airbag is connected to a corresponding inflating member, after the inflating member inflates the airbag, the friction force between the inner ring of the airbag and the guide post 14 increases, thereby hindering the elastic force of the elastic member 41.

[0060] In this embodiment, the annular columnar structure of the airbag can enable the guide post 14 to be inserted into the space in the middle thereof. After the airbag is inflated, the volume of the airbag increases, compressing the space in the middle thereof, thereby forming a structure similar to gripping the guide post 14, so that the spring 562 also needs to overcome the friction force between the inner ring of the airbag and the guide post 14 during the process of compression or expansion, thereby improving or reducing the deformation ability of the spring 562.

[0061] Further, a pressure maintaining valve is arranged between the airbag and the inflating member.

[0062] The pressure maintaining valve can maintain the air pressure in the airbag, thereby maintaining the friction force between the airbag and the guide post 14.

[0063] Further, a pressing column 561 is provided at the top of the installation groove 56. The pressing column 561 is of a hollow structure, and a spring 562 is arranged inside the pressing column 561. In an unloaded state, the spring 562 protrudes above the pressing column 561. After the accommodating tank body 51 is driven by the longitudinal driving cylinder 57 and inserted into the installation groove 56, the pressing column 561 abuts against the hanging ear 54, and the spring 562 applies an upward elastic force to the hanging ear 54.

[0064] After the accommodating tank body 51 is inserted into the installation groove 56, both the accommodating groove and the accommodating tank body 51 will be subjected to the vibration emitted by the vibration mechanism 2. At this time, relative movement may occur between the two, thereby changing the pressing action of the partition plate 53 on the damping particles 52 above it, causing the damping particles 52 to move relatively and absorb part of the vibration, interfering with the testing process. Therefore, in this embodiment, a spring 562 is arranged inside the pressing column 561. The spring 562 can generate an upward elastic force to further press the partition plate 53 upward, so that the partition plate 53 always tightly presses the damping particles 52 above it during operation, preventing them from moving relatively.

[0065] Further, it includes a rotating cylinder 58. The rotating cylinder 58 is driven by the longitudinal driving cylinder 57, and the rotating cylinder 58 drives the accommodating tank body 51 to rotate.

[0066] After the test is completed, most of the damping particles 52 above the partition plate 53 fall to its lower part. At this time, through the rotation of the rotating cylinder 58, the accommodating tank body 51 is rotated 180°, so that it can automatically enter the next test work.

[0067] Further, the partition plate 53 is provided with an opening groove. The controllable opening 55 includes a rotating plate hinged to one side of the opening groove. The rotating plate is driven by a rotating motor to block or open the opening groove.

[0068] In this embodiment, by rotating the rotating plate, the falling time of the damping particles 52 can be controlled, the falling weight can be adjusted approximately, and then different amounts of damping particles 52 can be used to absorb vibrations with different amplitudes and frequencies to generate corresponding vibrations.

[0069] Further, the damping particles 52 are spherical particles made of one or more of metal, plastic, rubber, glass, and ceramic, and the diameter of the damping particles 52 is 1 - 5 mm.

[0070] In this embodiment, the damping particles 52 are directly adopted from the prior art.

[0071] Further, the control method includes:

[0072] S1. Control the controllable opening 55 to close, so that all the damping particles 52 are accommodated in the upward-facing cavity within the accommodating tank body 51. Control the longitudinal drive cylinder 57 to drive the accommodating tank body 51 to insert into the installation groove 56 and be pressed tightly. Control the tremor mechanism 2 to vibrate. During the vibration of the tremor mechanism 2, control the damping of the adjustable damper 42 to gradually increase, so that the switch operating mechanism 3 is subjected to different fluctuations.

[0073] S2. Control the damping of the adjustable damper 42 to reach the maximum. Control the controllable opening 55 to open and let a part of the damping particles 52 fall into the downward-facing cavity within the accommodating tank body 51. Control the longitudinal drive cylinder 57 to drive the accommodating tank body 51 to insert into the installation groove 56 and be pressed tightly. After the damping particles 52 absorb a part of the vibration, the amplitude or frequency of the vibration received by the switch operating mechanism 3 is changed.

[0074] S3. Repeat S2 until all the damping particles 52 fall into the downward-facing cavity within the accommodating tank body 51, and the test is completed.

[0075] In this method, step S1 corresponds to controlling the switch operating mechanism 3 to be subjected to different fluctuations. At this time, the tremor mechanism 2 can be set to work in the low-frequency region so that it can generate large and low-frequency fluctuations to simulate sea fluctuations, sharp turns of vehicles, etc. By controlling the damping of the adjustable damper 42 to gradually increase, the support rigidity between the upper leg 11 and the lower leg 12 can be controlled, so that it can fluctuate to different degrees.

[0076] S2 - S3 of this method can control the number of damping particles 52 falling below the partition plate 53. At the same time, different ratios of the falling numbers of different vibration adjustment mechanisms 5 can be carried out to achieve various ratios of absorption frequencies and amplitudes, so as to expand and obtain more vibrations, thereby performing a full-range vibration test on the switch.

Controlling the longitudinal driving cylinder (57) to drive the accommodating tank body (51) to be inserted into the installation groove (56) and pressed tightly. During the vibration of the vibration mechanism (2), controlling the damping of the adjustable damping member (42) to gradually increase, so that the switch operating mechanism (3) is subjected to different fluctuations. S2, controlling the damping of the adjustable damping member (42) to reach the maximum. Controlling the controllable opening (55) to open and a part of the damping particles (52) to fall into the downward cavity of the accommodating tank body (51). Controlling the longitudinal driving cylinder (57) to drive the accommodating tank body (51) to be inserted into the installation groove (56) and pressed tightly. After the damping particles (52) absorb a part of the vibration, the amplitude or frequency of the vibration received by the switch operating mechanism (3) is changed. S3, repeating S2 until all the damping particles (52) fall into the downward cavity of the accommodating tank body (51), and the test is completed.
