As shown in fig. 1, the invention provides an external pressure resistance test device for power equipment, which comprises a test workbench 1, an adjusting rack 2 connected to the side of the test workbench 1, a pressure testing mechanism 3 mounted on the adjusting rack 2, a test base 4 mounted on the adjusting rack 2 and on the test workbench 1, a plane fixing mechanism 5 arranged on the test base 4, and a control system 6 in communication connection with the plane fixing mechanism 5 and the pressure testing mechanism 3.
In fig. 1, the test table 1 is taken as a working platform of the whole device, and a conveying device can be arranged at two ends of the test table 1 to convey a part to be detected to the test base 4, and the part to be detected can be manually placed or electrically conveyed to the plane fixing mechanism 5.
The embodiment provides two detection modes for different positions of different types of power external parts, so that the inspection efficiency of the device is improved, the consumable rate of the device is reduced, and the device is suitable for inspecting the power external parts before delivery and after being used for a period of time.
The first detection mode is as follows: in the plane compression test, a plane fixing mechanism 5 is mainly arranged on a test base 4 to fix a component to be detected, the power externally-applied component before leaving a factory is detected, the pressure bearing capacity of the power externally-applied component is mainly checked, so that the compression resistance information of the power externally-applied component is obtained, and the service life and the condition of the power externally-applied component are conveniently recorded and judged.
In this embodiment, the plane fixing mechanism 5 inspects the part to be detected before leaving the factory, most of the specifications of the part to be detected are different, and the traditional detection device needs to be provided with different fixing devices to fix the part to be detected, so that the waste of test equipment is excessive, and therefore the following device suitable for most of the parts to be detected is arranged in this embodiment.
The plane fixing mechanism 5 is divided into two parts, namely a positioning fixing component 51 and a width adjusting component 52, in order to fix the whole part to be detected, a plurality of positioning fixing components 51 are arranged in the device, in addition, the width adjusting component 52 is arranged aiming at the positioning fixing components 51 to adjust the internal fixing area of the positioning fixing components 51, namely, the internal fixing range of the positioning fixing components 51 is adjusted to adapt to the parts with different specifications for inspection.
As shown in fig. 2, the positioning and fixing assembly 51 includes fixing posts 511 (only one fixing post 511 is shown in the drawing, in this embodiment, at least two fixing posts 511 are provided, and two sides of the component to be detected are respectively fixed), a fixing block 512 embedded in the fixing posts 511, and a threaded lifting rod 513 connected to the fixing block 512, a lower end surface of one end of the fixing block 512 is in close contact with the component to be detected, the fixing block 512 is embedded in the threaded lifting rod 513, a through groove 514 for the threaded lifting rod 513 to be embedded and the fixing block 512 to pass through is provided in the fixing post 511, a driving threaded cylinder 515 is provided in the through groove 514, a first driving motor 516 is connected to a lower end of the driving threaded cylinder 515, the first driving motor 516 is in communication connection with the control system 6, and the threaded lifting rod 513 is in the driving threaded cylinder 515.
When the component to be detected is fixed, the component to be detected is placed between the fixing spaces formed by the fixing columns 511, after the component to be detected is placed, the control system 6 sends a driving instruction to the first driving motor 516 to control the first driving motor 516 to operate, the first driving motor 516 drives the driving threaded barrel 515 to rotate so as to drive the threaded lifting rod 513 to rotate, the threaded lifting rod 513 normally drives the fixed block 512 connected above to rotate together, but the fixed block 512 is limited horizontally by the through groove 514 in the device, so under the driving action of the rotation of the threaded lifting rod 513, the fixed block 512 moves up and down, when the component to be detected needs to be fixed, the fixed block 512 needs to be controlled to move down, and when the component to be detected needs to be disassembled, the fixed block 512 needs to be controlled to move up.
In addition, before the component to be detected is fixed, the fixing column 511 needs to be adjusted to be close to the side edge of the component to be detected, in the embodiment, the width adjusting assembly 52 is adopted to achieve the purpose, and the structure of the width adjusting assembly 52 is as follows;
the width adjusting assembly 52 comprises a driving threaded rod 521 in threaded connection with the inner portion of the lower end of the fixed column 511, and a second driving motor 522 connected to one end of the driving threaded rod 521, the second driving motor 522 is in communication connection with the control system 6, a first threaded groove 523 for the driving threaded rod 521 to pass through is formed in the fixed column 511, and an adjusting groove 524 (shown in fig. 3) for the fixed column 511 to slide and for the driving threaded rod 521 to be placed is formed in the test base 4.
The embodiment of the width adjustment assembly 52 is as follows, the control system 6 sends a driving instruction to the second driving motor 522 to drive the second driving motor 522 to operate, the second driving motor 522 drives the driving threaded rod 521 to rotate, the driving threaded rod 521 should drive the fixing column 511 to rotate, but the fixing column 511 is limited by the adjusting slot 524, so that the driving threaded rod 521 rotates to drive the fixing column 511 to move left and right, and the area of the fixing space is changed when the fixing column 511 slides in the adjusting slot 524 which is set in a specified manner, for example: the area of the fixing space is increased when the two fixing posts 511 slide inwards, and the area of the fixing space is decreased when the two fixing posts 511 slide outwards.
In addition, the width adjustment assembly 52 provided in this embodiment may also drive the component to be detected to move after fixing the component to be detected so that the pressure testing mechanism 3 can perform pressure resistance testing on different portions of the component to be detected.
The second detection mode is as follows: compression test on the power equipment, the difficult dismantlement of the part of exerting outward on the power equipment, this embodiment adopts and directly carries out compression test on the power equipment, has saved and has exerted the manpower and materials that the part carries out the dismantlement outward, has improved detection efficiency moreover.
The first detection mode is to detect a single external component on a plane, the second detection mode is to detect the external component on the power equipment, when the external component on the power equipment is detected, the pressure testing mechanism 3 may be stopped by the plane fixing mechanism 5 when the position conversion is carried out, and in order to avoid being stopped by the plane fixing mechanism 5 and facilitate the whole height of the pressure testing mechanism 3, the adjusting rack 2 is designed in the invention.
Set up regulation frame 2 into the device that can height-adjusting, more easily find the position with the last component adaptation of exerting oneself of power equipment when pressure accredited testing organization 3 carries out the position conversion, we set up regulation frame 2 into four spliced poles 21 (only two are drawn in the figure) of 2 fixed connection side edges on test bench 1, threaded connection is in the rotation screw thread post 23 of spliced pole 21 upper end, threaded connection is at support column 24 on rotating screw thread post 23, connect installation roof 22 in support column 24 upper end, support column 24 sets up the four corners department of terminal surface under installation roof 22, set up the second thread groove 25 that supplies to rotate screw thread post 23 screw thread access on spliced pole 21 and the support column 24, be connected with third driving motor 26 on the rotation screw thread post 23, third driving motor 26 is connected with control system 6 communication.
