Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Example
[0030] Reference Figure 1-Figure 5 This embodiment provides a HTRB high temperature reverse bending test device, including a bottom plate 1, a platform 2 is fixed on the top of the bottom plate 1, a placing table 3 is arranged on the top of the platform 2, a fixing plate 4 is fixed on the side of the platform 2, a height adjustment mechanism is arranged at the bottom of the fixing plate 4, and the output end of the height adjustment mechanism is a pressing plate 5; a side plate 6 is fixed on the side of the bottom plate 1, the side plate 6 is rotatably connected with a rotating shaft 7, a vertical plate 8 is fixed at one end of the rotating shaft 7, a horizontal plate 1 9 and a horizontal plate 2 10 are respectively fixed at the top and bottom ends of the vertical plate 8, a height adjustment mechanism is arranged at the bottom of the horizontal plate 1 9, and the output end of the height adjustment mechanism is an adjustment plate 1 11, an adjustment plate 2 12 is arranged on the top of the horizontal plate 2 10, a guide shaft 13 is rotatably installed at the bottom of the adjustment plate 11 and the top of the adjustment plate 2 12, and a driving mechanism 1 for driving the workpiece to move is arranged at the top of the bottom plate 1;
[0031] The back side of the side plate 6 is provided with a second driving mechanism for driving the rotating shaft 7 to rotate;
[0032] In this embodiment, the bottom plate 1 and the side plate 6 are both components of the HTRB equipment, and the platform 2 and the driving mechanism 2 have a certain height, providing space for the rotation of the rotating shaft 7 to drive the vertical plate 8, the horizontal plate 1 9 and the horizontal plate 2 10 to rotate. During the test, the workpiece to be tested is placed on the adjusting plate 2 12 and the placing table 3, and the driving mechanism 1 clamps one end of the workpiece to be tested to adjust the position of the workpiece to be tested relative to the adjusting plate 2 12 and the placing table 3, thereby adjusting the bending test position. After the position adjustment is completed, the height adjustment mechanism is operated to clamp the pressing plate 5 and the guide shaft 13 to clamp the workpiece to be tested, and then the driving mechanism 2 is operated to make the rotating shaft 7 reciprocate. During the reciprocating swing of the rotating shaft 7, the vertical plate 8, the horizontal plate 1 9, the horizontal plate 2 10, the adjusting plate 2 12, the adjusting plate 1 11 and the guide shaft 13 are driven to rotate around The workpiece to be tested is swung along the axis of the rotating shaft 7. Since the guide shaft 13 on the adjusting plate 1 11 and the adjusting plate 2 12 clamps the workpiece to be tested, the workpiece to be tested is driven to swing. The bending position is the position of the workpiece to be tested where the pressing plate 5 is pressed near one end of the rotating shaft 7. When the bending amplitude needs to be adjusted, the driving mechanism 2 is operated to change the swing angle of the rotating shaft 7. When the test position needs to be adjusted, the height adjustment mechanism is operated to release the workpiece to be tested, and then the driving mechanism 1 is operated to slide the workpiece to be tested, and the position to be tested is placed directly below the pressing plate 5 near one end of the rotating shaft 7, and then the above process is repeated. Compared with the prior art, there is no need to manually adjust the position of the workpiece to be tested, thereby reducing the time of turning the HTRB equipment on and off, and the bending amplitude can be adjusted, thereby improving the test efficiency and practicality.
[0033] During the bending process of the workpiece to be measured, the guide shaft 13 will move and rotate relative to the workpiece without sliding friction with the workpiece, thereby reducing damage to the workpiece.
[0034] As a preferred solution of the present invention, the driving mechanism 2 includes a gear 14 fixedly connected to the rotating shaft 7, a track 15 fixedly connected to the side plate 6, and a rack 16 slidably connected to the track 15, and the rack 16 meshes with the gear 14. Figure 2 As shown, when the rack 16 moves along the track 15, since the rack 16 is meshed with the gear 14, the moving rack 16 can drive the gear 14 and the shaft 7 to rotate. When the rack 16 reciprocates, it will be converted into the swing of the shaft 7.
[0035] A connecting plate 17 is fixed to the bottom end of the rack 16, and the connecting plate 17 has a long hole. A power mechanism 18 is fixed to the side plate 6, and the power mechanism 18 is a servo motor. A drive shaft 19 is rotatably connected to the side plate 6. The power mechanism 18 and the drive shaft 19 are connected through a synchronous belt transmission. The drive shaft 19 is driven to rotate by controlling the rotation of the output shaft of the power mechanism 18.
[0036] A driving disk 20 is fixed at the end of the driving shaft 19, and a translation assembly is arranged radially along the driving disk 20. More specifically, the translation assembly includes a screw rod 22 rotatably connected to the driving disk 20, the screw rod 22 is threadedly connected to a moving block 23, the driving disk 20 is fixed with a track 2, and the track 2 is slidably connected to the moving block 23; a driving shaft 21 is fixed at the output end of the translation assembly, the driving shaft 21 is fixed on the moving block 23, and the driving shaft 21 passes through the long hole;
[0037] In this embodiment, the operating principle of the driving mechanism 2 is as follows: when the servo motor rotates, the driving shaft 19 is driven to rotate by the synchronous belt. As the driving shaft 19 rotates, the driving disk 20 also rotates. A driving shaft 21 is fixed on the moving block 23. The driving shaft 21 passes through the long hole on the connecting plate 17. As the driving shaft 21 revolves, the driving shaft 21 drives the connecting plate 17 and the rack 16 to move along the track 15. Since the rotation trajectory of the driving shaft 21 is circular, the rack 16 and the connecting plate 17 are driven. 7 reciprocates, thereby making the shaft 7 and the gear 14 reciprocate; when the swing angle of the gear 14 and the shaft 7 needs to be adjusted, it is only necessary to adjust the maximum displacement of the rack 16, at this time, the screw rod 1 22 is rotated, because the screw rod 1 22 is threadedly connected with the moving block 23, and the moving block 23 slides on the track 2, so the screw rod 25 is rotated to make the moving block 23 and the driving shaft 21 move radially along the driving disk 20, thereby adjusting the distance between the driving shaft 21 and the driving shaft 19, and then adjusting the reciprocating swing range of the shaft 7.

Figure 1 As shown, the height of the workpiece to be measured can be adjusted. Since the thicknesses of different workpieces to be measured are different, the workpiece to be measured can be adjusted to a centered state by adjusting the height of the workpiece to be measured.

Since the two sliders 24 are respectively threadedly connected to the forward thread and the reverse thread on the screw rod 25, the two sliders 24 move in opposite directions, and this movement in opposite directions is transmitted to the placement table 3, the adjustment plate 2 12, the adjustment plate 1 11 or the pressure plate 5 through the inclined rod 26, so that these components can be smoothly raised or lowered.
[0040] As a preferred solution of the present invention, the driving mechanism 1 includes a base 27 telescopically connected to the bottom plate 1. Figure 1 As shown, more specifically, the bottom of the base 27 is an electric telescopic rod 28, and the height of the base 27 is controlled by the electric telescopic rod 28 to adapt to the thickness of the workpiece. The base 27 is rotatably connected to a screw rod 3 29, and the screw rod 3 29 is threadedly connected to a drive plate 30. A linear mechanism 31 is fixed on the top of the drive plate 30, and the output end of the linear mechanism 31 is a positioning plate 32. When in use, the height of the drive plate 30 is adjusted by controlling the electric telescopic rod 28 according to the thickness of the workpiece, and the workpiece is placed on the drive plate 30. The linear mechanism 31 is operated to make the positioning plate 32 descend to press the workpiece, thereby fixing one end of the workpiece. When the position of the workpiece needs to be adjusted, the screw rod 3 29 can be rotated.
[0041] As a preferred solution of the present invention, the height adjustment mechanism further includes a motor 1 disposed at one end of the screw rod 25, which does not require manual control and improves the degree of automation.
[0042] As a preferred solution of the present invention, each of the sliding blocks 24 is provided with at least two inclined rods 26 to improve the lifting stability.
[0043] As a preferred solution of the present invention, a motor 2 is provided at one end of the screw rod 3 29, and the screw rod 3 29 is driven to rotate by controlling the motor 2, thereby improving the degree of automation.
[0044] As a preferred solution of the present invention, the driving plate 30 is slidably connected to the base 27 to prevent the driving plate 30 from rotating along with the screw rod 3 29 .
[0045] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
