Detailed Description
In order to clearly explain the technical features of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the invention.
For convenience of description, a coordinate system is now defined as shown in fig. 1.
As shown in fig. 1, the structural strength simulation parameter verification calibration device comprises a base 1, wherein the base 1 comprises a transverse plate 11 and a vertical plate 12 arranged at one end of the transverse plate 11, and the transverse plate 11 and the vertical plate 12 form an L shape together. As a specific embodiment, the horizontal plate 11 and the vertical plate 12 in this embodiment are fixedly connected by welding.
As shown in fig. 1, a pressure gauge clamping assembly 2 for clamping a pressure gauge 5 is arranged on the transverse plate 11. The pressure gauge clamping assembly 2 comprises a square frame 21, and the frame 21 is slidably connected with the transverse plate 11. As shown in fig. 1 and 4, the upper end of the vertical plate 12 is provided with a pressing block 13, and the pressing block 13 is fixedly connected with the vertical plate 12 through a pressing bolt. The sample 4 is pressed between the pressing block 13 and the upper end face of the vertical plate 12, and the front end of the sample 4 extends forwards through the frame 21. A pressure gauge 5 is provided inside the frame 21 above the sample 4. The pressure gauge 5 is fixedly connected with the frame 21 through a first clamping plate 22 and a second clamping plate 23 which are respectively arranged at the front side and the rear side of the pressure gauge 5. The frame 21 is provided with a scale 28 on the front side of the frame in the vertical direction. In this embodiment, a graduated scale 28 is disposed on the front side of the left frame of the frame 21.
Furthermore, because a simulation model needs to be established according to an actual experimental model during working, namely the position of a pressure point in the simulation model is set according to the position of the pressure point of the calibration device, and keeping the consistency of the pressure point is a precondition for ensuring the accuracy of a calibration result. Therefore, the position of the pressure point needs to be measured manually by a ruler before calibration, which is complicated on one hand and inaccurate on the other hand.
For this purpose, as shown in fig. 8, a scale (not shown) is provided on the right side surface of the cross plate 11, and a pointer is provided at the lower end of the right side surface of the frame 21 and is located at the middle in the thickness direction of the frame 21 (the dimension in the front-rear direction is the thickness). Therefore, when the pressure gauge 5 is installed, as long as the pressure head of the pressure gauge 5 is located in the middle of the thickness direction of the frame 21, the scales indicated by the pointer are the positions of the pressure applying points of the pressure gauge 5, measurement is not needed, and reading is convenient.
Further, since the pressure gauge 5 is a commercially available part, and the pressure gauge 5 of different manufacturers has different shapes and sizes, when the pressure gauge 5 is damaged, the new pressure gauge 5 may not meet the installation requirements.
For this, as shown in fig. 1, 8 and 9, the left and right ends of the first clamping plate 22 are respectively provided with a clamping bolt, and the clamping bolt sequentially penetrates through the first clamping plate 22, the frame 21 and the second clamping plate 23 along the front-back direction, and the rear end of the clamping bolt is provided with a second locking nut 251. The holes for accommodating the clamping bolts on the first clamping plate 22, the frame 21 and the second clamping plate 23 are all through holes. The clamping bolt is provided with an adjusting nut 252 between the first clamping plate 22 and the frame 21, and between the second clamping plate 23 and the frame 21.
Further, for convenience of adjustment, as shown in fig. 1 and 5, an oblong hole 211 is provided on a right frame of the frame 21 along a vertical direction, and the oblong hole 211 is located in a middle of the frame 21 in a thickness direction. A second indicator light 29 is arranged on the inner side surface of the left frame of the frame 21, and the position of the second indicator light 29 corresponds to the position of the oblong hole 211. As shown in fig. 4, a first indicator light 131 is disposed at a middle position of the front side of the pressing block 13.
Thus, when the pressure gauge 5 needs to be replaced, one surface of the pressure gauge 5 is firstly attached to the first clamping plate 22, then the position of the pressure gauge 5 along the left-right direction is adjusted, the pressure gauge is observed from the front side until the pressure head of the pressure gauge 5 shields the first indicator lamp 131, then the second clamping plate 23 is installed, and the second locking nut 251 is locked. At this time, the pressure gauge 5 has been clamped between the first clamping plate 22 and the second clamping plate 23, but the position of the pressure gauge 5 in the front-rear direction is not fixed. And then the pressure gauge 5 is moved along the front-back direction, the clamping bolt moves back and forth in the through hole of the frame 21 and is observed from the oblong hole 211 until the pressure head of the pressure gauge 5 shields the second indicator light 29, and then the adjusting nuts 252 are respectively screwed.
Further, since the pressure gauge 5 is not reliable enough only by the friction between the first clamping plate 22 and the second clamping plate 23 and the pressure gauge 5 when applying pressure to the sample 4, the pressure gauge 5 may slide relative to the first clamping plate 22 and the second clamping plate 23, and therefore, it is reliable to make the upper end surface of the pressure gauge 5 abut on the upper frame of the frame 21. However, the pressure gauge 5 is a commercially available part, and the pressure gauge 5 of different manufacturers has different outer shapes and sizes, and when the pressure gauge 5 is damaged, the new pressure gauge 5 may not satisfy the installation requirements.
For this purpose, as shown in fig. 1 and 10, an upper pressure plate 26 is disposed inside the frame 21 above the pressure gauge 5, a guide post 261 is disposed on the upper pressure plate 26, and a through hole for receiving the guide post 261 is disposed on an upper rim of the frame 21. The upper frame of the frame 21 is connected with a puller bolt 27 through a thread, and the lower end surface of the puller bolt 27 is abutted against the upper pressure plate 26.
This allows on the one hand to satisfy different sizes of pressure gauges 5; on the other hand, a button is arranged on the front side surface of the pressure gauge 5, so that the clamping positions of the first clamping plate 22 and the second clamping plate 23 can be adjusted while the upper end surface of the pressure gauge 5 is reliably pressed, and the position of the button is avoided.
As a specific implementation manner, the pressure gauge 5 in this embodiment adopts a constant pressure gauge 5, and the constant pressure gauge 5 is the prior art and is not described herein again.
As a specific implementation manner, in the present embodiment, as shown in fig. 1 and fig. 6, the transverse plate 11 is provided with at least two T-shaped slideways 111 arranged along the front-back direction. As a specific implementation manner, the number of the T-shaped slideways 111 in this embodiment is two. Every T type slide 111 in all be provided with a sliding bolt 3, just sliding bolt 3's head is located the T type spout in, can follow T type slide 111 slide from beginning to end. As shown in fig. 7, the upper end of the sliding bolt 3 extends upward through the lower frame of the frame 21, and a through hole for receiving the sliding bolt 3 is provided on the lower frame of the frame 21. A first locking nut 31 is disposed on the sliding bolt 3 at an upper portion of a lower frame of the frame 21. When the first locking nut 31 is loosened, the frame 21 can slide along the T-shaped slideway 111, and when the first locking nut 31 is tightened, the position between the frame 21 and the transverse plate 11 is locked.
Preferably, as shown in fig. 11, the head of the slide bolt 3 has a square shape.
Further, in order to ensure the reliability of clamping the pressure gauge 5, as shown in fig. 2 and 3, rubber pads 24 are respectively provided on the inner side surfaces of the first clamping plate 22 and the second clamping plate 23 (the side opposite to the first clamping plate 22 and the second clamping plate 23 is the inner side), and on the lower side surface of the upper pressing plate 26.
