The present invention, by providing a slide, a clamping plate and a bidirectional driving assembly, can clamp and fix the broken plates on both sides at the moment of breaking when the plates exceed the load limit, and absorb the impact force due to the instantaneous elastic deformation, thereby effectively preventing the plates from irregularly catapulting and increasing safety.

[0021] 2. The present invention, by configuring the bidirectional driving assembly to be an oil transmission based on cylinder body 2 and piston 1, can, on the one hand, utilize the rodless chamber pressure of cylinder body 1 during testing to realize automatic clamping at the moment of fracture, thereby simplifying the control logic while avoiding the delay caused by the electric control and ensuring the reliability of clamping; on the other hand, it can also ensure that the clamping plate is not in a clamping state during the test phase, and the plate is only placed on the slide, thereby preventing inaccurate test results caused by additional force applied to the plate.

[0022] 3.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Embodiment 1:

[0034] A testing device for the production of environmentally friendly compression-resistant artificial boards, such as Figure 1-Figure 7 As shown, it includes a base 1, the top outer wall of the base 1 is slidably connected with two sets of controllable clamping mechanisms 2 through a slide rail 6, and a gantry 3 is fixed to the top of the base 1 by bolts, and the bottom of the gantry 3 is cooperated with a pressure block 5 through a pressure mechanism 4.

[0035] The controllable clamping mechanism 2 includes a slide 7 slidably connected to the outer wall of the slide rail 6 and a clamping plate 8 slidably connected to the slide 7 through a guide rod 9, the outer wall of the guide rod 9 is sleeved with a spring 10, a lifting rod 11 is fixed to the top outer wall of the clamping plate 8 by bolts, the side wall of the lifting rod 11 is rotatably connected to a connecting rod 12, and a bidirectional driving component 13 is fixed to the top of the slide 7 for horizontally and linearly driving the other end of the connecting rod 12.

[0036] The pressure mechanism 4 includes a cylinder body 17 fixed to the base 1 and a piston assembly 15 movably fitted on the inner wall of the cylinder body 17, the bottom of the piston assembly 15 is connected to the pressure block 5 through a piston rod 14, and the top of the cylinder body 17 is fixedly connected to a two-way oil pump 16, and the other end of the two-way oil pump 16 is connected to the oil tank through a pipeline.

[0037] When the device is in use, the plate can be placed on the lower upper surface of the slide 7, that is, the bottom of the clamping plate 8, and then the oil in the oil tank is pumped into the cylinder 17 by the two-way oil pump 16. The piston assembly 15 moves downward under the action of the oil pressure, thereby driving the pressure block 5 to move downward through the piston rod 14 until the pressure block 5 contacts the plate. The two-way oil pump 16 continues to apply oil pressure to the cylinder 17, thereby using the oil pressure to generate a downward load. At this time, the plate will be slightly elastically deformed by the longitudinal action. As the load continues to increase, when it reaches the limit of the plate, the plate will break. At the moment of breaking, The end limit of the pressure block 5 disappears instantly, so that the pressure block 5 has a tendency to move downward instantaneously. The movement trend is greater than the speed of the two-way oil pump 16 to deliver oil inward to drive the pressure block 5 to move downward, so that the oil in the inner cavity of the cylinder body 17 will briefly form a negative pressure state. At the same time, the lateral driving force of the two-way drive component 13 on the connecting rod 12 disappears and becomes a lateral pulling force. Combined with the pulling force of the spring 10, the lifting rod 11 is lowered through the connecting rod 12, so that the clamping plate 8 is lowered to clamp the broken plates on both sides, absorb the impact force due to the instantaneous elastic deformation, and prevent splashing.

[0038] The device, by providing a slide 7, a clamping plate 8 and a bidirectional driving assembly 13, can clamp and fix the broken plates on both sides at the moment of breaking when the plates exceed the load limit, and absorb the impact force due to the instantaneous elastic deformation, thereby effectively preventing the plates from irregularly catapulting and increasing safety.

[0039] To solve the driver problem; Figure 4 As shown, the bidirectional drive assembly 13 includes a cylinder body 18 fixed to the slide 7 and two pistons 20 symmetrically slidably connected to the inner wall of the cylinder body 18, a piston rod 21 is fixed to the side wall of the piston 20, the end of the piston rod 21 is rotatably connected to the connecting rod 12, and an oil nozzle 19 connected to the inner cavity of the cylinder body 18 is fixed in the middle of the cylinder body 18.

[0040] The top of the oil nozzle 19 is connected to a connecting pipe 22, and the other end of the connecting pipe 22 is connected to and communicated with the top rodless chamber of the cylinder body 17.

[0041] When in the test stage, the oil pressure in the rodless chamber of cylinder body 17 is positive, thereby generating positive pressure in cylinder body 2 18, repelling piston 1 20 outward, thereby raising the clamping plate 8 through connecting rod 12 and not clamping the plate. When the plate breaks, negative pressure is instantly generated in cylinder body 17, and the negative pressure will be transmitted to cylinder body 2 18, thereby attracting piston 1 20 inward and lowering the clamping plate 8.

[0042] This device, by setting the bidirectional drive component 13 to be an oil transmission based on cylinder body 18 and piston 1 20, can, on the one hand, utilize the rodless chamber pressure of cylinder body 17 during testing to achieve automatic clamping at the moment of fracture, thereby simplifying the control logic while avoiding the delay caused by electric control and ensuring the reliability of clamping. On the other hand, it can also ensure that the clamping plate 8 is not in a clamping state during the test phase, and the plate is only placed on the slide 7, thereby preventing additional force from being applied to the plate and causing inaccurate test results.

[0043] To solve the induction problem; Figure 7 As shown, the piston rod 14 is slidably matched with the pressure block 5 through a slider 32, and a piezoelectric ceramic 31 is fixed to the inner wall of the pressure block 5 located at the bottom of the slider 32.

[0044] When a load is applied, the piezoelectric ceramic 31 acts as a force transmission medium between the piston rod 14 and the pressure block 5. It will generate voltage under pressure. The voltage generated by the piezoelectric ceramic 31 can be used to obtain the load size, thereby detecting the compressive fracture limit of the plate.

[0045] When the present embodiment is in use, the plate can be placed on the lower upper surface of the slide 7, that is, the bottom position of the clamping plate 8, and then the oil in the oil tank is pumped into the cylinder 17 by the two-way oil pump 16. The piston assembly 15 moves downward under the action of the oil pressure, thereby driving the pressure block 5 to move downward through the piston rod 14 until the pressure block 5 contacts the plate. The two-way oil pump 16 continues to apply oil pressure to the cylinder 17, thereby using the oil pressure to generate a downward load. At this time, the plate will be slightly elastically deformed by the longitudinal action. As the load continues to increase and reaches the limit of the plate, the plate will break. At the moment of breaking, the end limit of the pressure block 5 disappears instantly, so that the pressure block 5 has an instantaneous downward movement. The movement trend is greater than the speed of the two-way oil pump 16 conveying oil inward to drive the pressure block 5 to move downward, so that the inner cavity oil of the cylinder body 17 will form a negative pressure state for a short time, and at the same time, the lateral driving force of the two-way driving component 13 on the connecting rod 12 disappears and becomes a lateral pulling force, and then cooperates with the pulling force of the spring 10 to make the lifting rod 11 descend through the connecting rod 12, so that the clamping plate 8 descends to clamp the broken plates on both sides, absorb the impact force caused by the instantaneous elastic deformation, and prevent splashing. When in the test stage, the rodless cavity oil pressure of the cylinder body 17 is positive pressure, so that positive pressure is generated in the cylinder body 2 18, and the piston 20 is repelled outward, so The clamping plate 8 is raised by the connecting rod 12, and the plate is not clamped. When the plate breaks, negative pressure is instantly generated in the cylinder body 17, and the negative pressure is transmitted to the cylinder body 2 18, thereby attracting the piston 20 inward and lowering the clamping plate 8. When the load is applied, the piezoelectric ceramic 31 serves as a force transmission medium between the piston rod 14 and the pressure block 5, and it will generate voltage under pressure, so that the voltage generated by the piezoelectric ceramic 31 can be used to obtain the load size, so as to detect the compressive fracture limit of the plate. When it is in a descending and load-applying state, the upper inner cavity of the cylinder body 17, that is, the rodless cavity of the cylinder body 17 is positive pressure, and the piston 3 2 8 will also move downward under the action of positive pressure, and the friction plate 25 will be moved inwardly through the connecting rod 27, so that the friction plate 25 will not contact the cylinder body 17. At the moment of rupture, the rodless cavity of the cylinder body 17 generates negative pressure, so that the piston 3 28 is moved outwardly under the elastic force of the spring 29 and the negative pressure, and the friction plate 25 is squeezed outwardly. The friction between the friction plate 25 and the inner wall of the cylinder body 17 is used to reduce the speed of the instantaneous movement of the entire piston assembly 15. When rising and resetting, since only the gravity needs to be overcome, the resetting force is small, and the negative pressure in the inner cavity of the cylinder body 17 is also small, so the friction between the friction plate 25 and the cylinder body 17 is also small, and it can move up reliably.

[0046] Embodiment 2:

[0047] A testing device for producing environmentally friendly compression-resistant artificial board materials is provided. In order to solve the safety problem, this embodiment makes the following improvements on the basis of embodiment 1: Figure 6As shown, the piston assembly 15 includes a piston 23 and a rectangular frame 24 welded to the top of the piston 23, the inner wall of the rectangular frame 24 is laterally slidably connected to a friction plate 25, the inner wall of the piston 23 is embedded with a vertically arranged cylinder body 30, the inner wall of the cylinder body 30 is slidably connected to a piston 3 28, the top of the piston 3 28 is rotatably connected to a connecting rod 27, and the other end of the connecting rod 27 is rotatably connected to the side wall of the friction plate 25.

[0048] The outer side surface of the friction plate 25 is provided with anti-slip grooves 26 .

[0049] The end surface of the piston 3 28 is buckled with a spring 29 , and the other end of the spring 29 is buckled with the inner wall of the cylinder body 3 30 .

[0050] When the present embodiment is in use, when it is in a descending and load-applying state, the upper inner cavity of the cylinder body 17, that is, the rodless cavity of the cylinder body 17 is under positive pressure, and the piston three 28 will also move downward under the action of the positive pressure, and the friction plate 25 will be moved inwardly through the connecting rod two 27, so that the friction plate 25 does not contact the cylinder body 17. At the moment of rupture, the rodless cavity of the cylinder body 17 generates negative pressure, so that the piston three 28 is moved outwardly under the elastic force of the spring two 29 and the negative pressure, and the friction plate 25 is squeezed outwardly. The friction between the friction plate 25 and the inner wall of the cylinder body 17 is used to reduce the speed of the instantaneous movement of the entire piston assembly 15. When rising and resetting, since only the gravity needs to be overcome, the resetting force is small, and the negative pressure in the inner cavity of the cylinder body 17 is also small, so the friction between the friction plate 25 and the cylinder body 17 is also small, and it can move up reliably.

[0051] The device, by configuring the piston assembly 15 as a combination of the piston 23, the rectangular frame 24, the friction plate 25 and other components, can, on the one hand, make use of the friction between the friction plate 25 and the cylinder body 17 to hinder the movement of the piston assembly 15 at the moment of fracture, thereby reducing the "impact force" generated by its instantaneous movement speed trend and causing component damage; on the other hand, it can also be reliably reset during the reset process, and the entire process is also controlled by the pressure in the cavity of the cylinder body 17, thereby simplifying the control logic.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
