Referring to fig. 1-5, the present invention provides a technical solution: the respirator vibration treatment test box comprises a box body 1, wherein a negative weight block 7 is fixedly arranged at the bottom of the box body 1. The box is characterized in that a placing plate 2 is arranged in the box 1, a non-directional vibration mechanism 3 is arranged at the bottom of the placing plate 2, a servo motor 4 is fixed in the box 1, the input end of the non-directional vibration mechanism 3 is connected with the output end of the servo motor 4, and an elastic reset mechanism 5 is arranged between the top of the box 1 and the placing plate 2.
The non-directional vibration mechanism 3 comprises a first air cylinder 301, the first air cylinder 301 is fixed on a rotating disc 302, the output end of the first air cylinder 301 is hinged with a push rod 303, the bottom of the placing plate 2 is fixed with a connecting piece 304, and the other end of the push rod 303 is hinged with the connecting piece 304 through an elastic hinge piece 6.
The link 304 is in the form of an inverted "concave" configuration, with the resilient hinge member 6 disposed within the recess of the link 304. The elastic hinge 6 comprises a hinge rod 601, the hinge rod 601 is fixed with one end of the top rod 303, two ends of the hinge rod 601 are movably connected with the inner wall of the notch of the connecting piece 304 through a bearing, a gear 602 is fixed on the hinge rod 601, a sliding rail 603 is fixedly installed on the connecting piece 304, a rack 604 meshed with the gear 602 is installed on the sliding rail 603 in a sliding manner, and an elastic element 605 is arranged between the rack 604 and the connecting piece 304.
The elastic reset mechanism 5 comprises a sleeve 501, one end of the sleeve 501 is fixed on the top of the inner wall of the box 1 through a universal shaft 502, the other end of the sleeve 501 is penetrated by a sliding rod 503, a sliding block 504 is fixed on one end of the sliding rod 503 positioned in the sleeve 501, a reset spring 505 is arranged between the sliding block 504 and the inner wall of the sleeve 501, and the other end of the sliding rod 503 is fixed on the top of the placing plate 2. The number of the elastic reset mechanisms 5 is four, and the four elastic reset mechanisms 5 are distributed at four corners of the placing plate 2.
The placing plate 2 is also provided with a clamping device 8. The clamping device 8 comprises two annular clamping belts 801, wherein pull rings 802 are sleeved on the clamping belts 801, and the pull rings 802 are fixed on the output ends of the air cylinders 803. The clamping band 802 has two, and the inside of the clamping band 802 is provided with a bump structure.
In the embodiment, the first cylinder 301, the servo motor 4 and the first electric hydraulic push rod 606 have different working frequencies, namely, the first cylinder 301, the servo motor 4 and the first electric hydraulic push rod 606. The rotary disk 302 is not located directly below the link 304, and the cylinder one 301 is not located at the center of rotation of the rotary disk 302.
In use, the respirator is placed on the placing plate 2, the clamping strip 801 is bound on the placing plate 2, and the clamping strip 801 is stretched by the air cylinder II 803 to clamp the respirator. After clamping the respirator, the door is closed and the test device is started.
After the testing device is started, the first air cylinder 301, the servo motor 4 and the electric hydraulic push rod 606 are synchronously started, after the testing device is started, the servo motor 4 can drive the rotating disc 302 to rotate, and the rotating disc 302 is not located right below the connecting piece 304, and the first air cylinder 301 is not located in the rotating center of the rotating disc 302. Therefore, the distance from the first cylinder 301 to the connecting piece 304 is changed continuously, in the process, the placing plate 2 can be pulled to shake up and down, and in addition, the first cylinder 301 can also slide up and down and is asynchronous with the shaking of the servo motor 4, so that the placing plate 2 can continuously shake up and down in different degrees. Thereby achieving the purpose of continuously shaking the respirator in different degrees in the vertical direction. And at the vertical in-process that rocks, because the work of cylinder 301, can drive the one end of ejector pin 303 and rock from top to bottom, at this in-process, because ejector pin 303 becomes the tilt state, consequently ejector pin 303 can promote to place board 2 and rock on the horizontal direction. And because the position of cylinder 303 all is different at every turn, consequently the size and the direction of shaking power all inequality at every turn in the horizontal direction to reached and to have made the purpose that place board 2 and last different degree rocks in the horizontal direction.
In addition, due to the arrangement of the elastic hinge part 6, when the cylinder 301 drives the top rod 303 to move, the top rod 303 can rotate around the hinge rod 601, in the process, the top rod 303 can drive the hinge rod 601 to rotate, when the hinge rod 601 rotates, the rack 604 is driven by the gear 602 to slide, in the process, the rack 604 extrudes the spring, so as to offset the force during rotation, meanwhile, the electric hydraulic push rod 606 works to drive the pressing plate 607 to be in different positions at each time, therefore, the elastic force of the spring is different, because the electric hydraulic push rod 606 and the cylinder 301 are not synchronous to operate, the offset force at each time is different, thereby ensuring that the force in the horizontal direction is different in the process of moving at each time.
Through the setting of elasticity canceling release mechanical system 5, when placing board 2 work, can drive litter 503 and remove, because be the synchronous motion of horizontal direction and vertical direction, consequently litter 503 can take place the condition of slope, because the existence of cardan shaft, can be so that sleeve 501 keeps different angles. When the position where the board 2 is placed moves, the slider 504 presses the return spring 505, and the movement is ended to return to the original position.
Through the setting of non-directional vibration mechanism, can be so that place board 2 while continuous carry on the horizontal direction and shake in the vertical direction, at this in-process, can carry out comprehensive detection of rocking to placing the respirator on placing board 2. After the test is finished, the box door is opened, and the respirator is taken down to detect whether the respirator is in good condition.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
