DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a laser three-dimensional displacement detection device based on a vibration table, such as Figures 1 to 8 As shown, it includes a support column 1 and a vibration table 20, a support column 2 is fixedly installed on the top of the support column 1, a detection head 3 is fixedly installed on the bottom wall and two side walls of the support table 2, the detection head 3 is a laser displacement sensor, and the data recorded by the detection head 3 can be transmitted to the background storage record, the bottom wall and side walls of the support table 2 are fixedly installed with a ring plate 4 corresponding to the detection head 3, a sleeve 5 is fixedly installed equidistantly around the side of the ring plate 4 away from the support table 2, a slide rod 6 is slidably inserted inside the sleeve 5, a first spring 21 is provided on the side of the slide rod 6 close to the ring plate 4, a plurality of slide rods 6 extend to the outside of the sleeve 5 at one end away from the ring plate 4 and are fixedly installed with a circular ring 7, the circular ring 7 and the ring plate 4 are fixedly connected by a telescopic cover 8, the telescopic cover 8 is a black telescopic sleeve, a magnet 9 is fixedly installed on the outside of the sleeve 5, the material of the circular ring 7 is iron, the outside of the circular ring 7 is provided with a heat dissipation component for accelerating the dissipation of its internal heat, and the outside of the support table 2 is provided with a detection component for cooperating with the detection head 3 for detecting the vibration table.

[0028] When in use, the detection component is connected to the vibration table 20, the ring 7 is pulled to separate it from the magnet 9, and the ring 7 is loosened. At this time, the compressed first spring 21 releases the force to move the slide bar 6 and the ring 7 in the direction close to the detection component. Then the ring 7 fits the detection component, and the vibration table 20 is started to vibrate it up and down, so that the detection component moves accordingly. At this time, the detection head 3 can be started to detect and record the displacement of the detection component. The detection head 3 in three directions can detect and record the three-dimensional displacement of the vibration table 20. When the detection component moves downward, the ring 7 below will be pressed to make it move with the slide bar 6. It then descends and compresses the first spring 21 to deform it and generate a force. When the detection component moves upward, the first spring 21 releases the force to carry the slide bar 6 and the ring 7 upward, so that the ring 7 can always fit with the detection component. In this process, the telescopic cover 8 can block the strong light from the outside to avoid the strong light from affecting the detection effect of the detection head 3. In the process of the up and down reciprocating movement of the ring 7 below, the heat dissipation component can accelerate the dissipation of the heat generated by the detection head 3 in each telescopic cover 8, so as to avoid the heat from accumulating in the telescopic cover 8 and being unable to dissipate, causing the high temperature of the detection head 3 to affect its work.

[0029] like Figure 2 and Figure 3 As shown, the heat dissipation assembly includes air holes 10 equidistantly arranged around the outside of the ring 7, a channel 11 connected to the inside of the telescopic cover 8 is opened on the outside of the support platform 2, the lower channel 11 is connected to the inside of the two upper rings 7 through a shunt pipe 12, and a one-way valve 13 is provided inside the shunt pipe 12 and inside the air hole 10.

[0030] When the lower ring 7 descends with the detection assembly, the one-way valve 13 in the air hole 10 is closed, and the one-way valve 13 in the lower channel 11 is opened. As the ring 7 descends, the air in the telescopic cover 8 is squeezed outward, and the air enters the remaining telescopic covers 8 through the lower channel 11 and the shunt pipe 12, and then is discharged outward through the remaining channels 11. When the lower ring 7 rises, air is pumped into the lower telescopic cover 8. At this time, the one-way valve 13 in the air hole 10 is opened, and the one-way valve 13 in the lower channel 11 is closed. As the ring 7 rises, the outside air is drawn into the lower telescopic cover 8 through the air hole 10. The subsequent principle is the same as above. With the reciprocating motion of the lower ring 7, the outside air can be continuously drawn into the lower telescopic cover 8, and then transported to the remaining telescopic covers 8, and finally discharged to the outside through the channel 11, so that the heat generated by the detection head 3 in the telescopic cover 8 can be continuously accelerated to dissipate outward, so as to avoid the detection head 3 from being overheated and affecting its use.

[0031] like Figure 2 As shown, the flow dividing pipe 12 is a corrugated hose.

[0032] When the circular ring 7 located on the side of the detection component is laterally squeezed by the vibration table, the shunt tube 12 can adapt to the movement caused by the squeezing.

[0033] like Figures 2 to 5 As shown, a side of the circular ring 7 away from the ring plate 4 is equidistantly provided with steel ball grooves, in which steel balls 14 are arranged, and a closing component for closing the gap between the circular ring 7 and the detection component is arranged outside the circular ring 7 .

[0034] The ring 7 moves with the steel ball 14 toward the detection component, and the steel ball 14 finally contacts with the surface of the detection component. The gap between the ring 7 and the detection component can be closed by the closing component. When the detection component reciprocates up and down, the steel ball 14 located on the side of the detection component slides with the detection component, which reduces the friction between the ring 7 on the side and the detection component. This prevents the ring 7 from being damaged by the up and down movement of the detection component due to excessive friction between the ring 7 and the detection component, thereby protecting the ring 7 and the slide bar 6.

[0035] like Figures 2 to 5 and Figure 7 As shown, the closed component includes a magnetic ring 15, which is made of a magnet. The magnetic ring 15 is fixedly connected to the circular ring 7 through a rubber sleeve 16, and the rubber sleeve 16 is black in color. Rotation grooves are equidistantly arranged around the inner side of the magnetic ring 15, and an iron plate 17 is rotatably installed in the rotation groove. A supporting groove that cooperates with the iron plate 17 is arranged on the outer side of the circular ring 7, and a slope is arranged on the side of the supporting groove close to the sleeve 5, and an arc surface away from the sleeve 5 is arranged at one end of the iron plate 17 located in the rotation groove.

[0036] The iron plate 17 is rotated toward the direction close to the rubber sleeve 16 so that the iron plate 17 is adsorbed and fixed to the inner wall of one side of the support groove. At this time, since the iron plate 17 is separated from the magnetic ring 15, the support of the magnetic ring 15 is cancelled. At this time, the magnetic ring 15 can be held and adsorbed and fixed to the surface of the detection component. At this time, the rubber sleeve 16, the magnetic ring 15 and the detection component close the gap between the circular ring 7 and the detection component, so as to prevent air leakage from affecting the process of the air below entering the telescopic cover 8 and then being discharged to the outside.

[0037] like Figure 1 As shown, the detection assembly includes a moving block 18 , a connecting rod 19 is fixedly mounted on one side of the moving block 18 , and one end of the connecting rod 19 away from the moving block 18 is fixedly connected to a vibration table 20 .

[0038] When the vibration table 20 moves up and down, it can cooperate with the connecting rod 19 to move the moving block 18 up and down.

[0039] like Figure 1 As shown, the moving block 18 is specifically a cubic component made of iron.

[0040] This allows the magnetic ring 15 to be adsorbed and fixed to the moving block 18 .

[0041] like Figure 1 As shown, the three detection heads 3 are respectively located directly below, directly in front of, and directly to the left of the moving block 18 .

[0042] The three detection heads 3 can detect and record the movement of the moving block 18 from three directions, thereby realizing three-dimensional displacement detection.

[0043] Working principle: When in use, pull the ring 7 to separate it from the magnet 9, loosen the ring 7, and the compressed first spring 21 releases its force to move the slide bar 6 and the ring 7 in the direction close to the moving block 18. Then the ring 7 fits with the moving block 18, and the vibration table 20 is started to make it move up and down for vibration, and the connecting rod 19 moves the moving block 18 up and down accordingly. At this time, the detection head 3 can be started to detect and record the displacement of the moving block 18. The detection head 3 in three directions can detect and record the three-dimensional displacement of the vibration table 20. When the moving block 18 moves downward, the ring 7 below will be pressed to make it descend with the slide bar 6, and the first spring 21 will be compressed to deform and generate a force, and the telescopic cover 8 will be The air inside is squeezed outwards, at this time the one-way valve 13 in the air hole 10 is closed, and the one-way valve 13 in the lower channel 11 is opened. As the lower ring 7 continues to descend, the air in the lower telescopic cover 8 is squeezed into the remaining telescopic covers 8 through the lower channel 11 and the shunt pipe 12, and then discharged outwards through the remaining channels 11. When the moving block 18 moves upward, the first spring 21 releases its force to carry the slide bar 6 and the ring 7 up, so that the ring 7 can always fit with the moving block 18. When the lower ring 7 rises, air is pumped into the lower telescopic cover 8. At this time, the one-way valve 13 in the air hole 10 is opened, and the one-way valve 13 in the lower channel 11 is closed. As the ring 7 rises, the outside air is pumped in through the air hole 10 To the lower telescopic cover 8, the subsequent principle is the same as above. With the reciprocating motion of the lower ring 7, the outside air can be continuously drawn into the telescopic cover 8 below, and then transported to the rest of the telescopic covers 8, and finally discharged to the outside through the channel 11, so that the heat generated by the detection head 3 in the telescopic cover 8 can be continuously accelerated to dissipate outward, so as to avoid the over-high temperature of the detection head 3 affecting its use. In this process, the telescopic cover 8 can block the strong light from the outside, so as to avoid the strong light from affecting the detection effect of the detection head 3; before use, rotate the iron plate 17 in the direction close to the rubber sleeve 16, so that the iron plate 17 is adsorbed and fixed to the inner wall of one side of the support groove. At this time, since the iron plate 17 is separated from the magnetic ring 15, the support of the magnetic ring 15 is cancelled, and it can be The magnetic ring 15 is held and fixed to the surface of the moving block 18. At this time, the rubber sleeve 16, the magnetic ring 15 and the moving block 18 close the gap between the circular ring 7 and the moving block 18. The circular ring 7 moves with the steel ball 14 in the direction close to the moving block 18, and the steel ball 14 finally contacts the surface of the moving block 18. When the moving block 18 reciprocates up and down, the steel ball 14 located on the side of the moving block 18 slides with the moving block 18, thereby reducing the friction between the circular ring 7 and the moving block 18 on the side, so that the circular ring 7 and the moving block 18 will not be driven by the moving block 18 when it moves up and down due to excessive friction between the circular ring 7 and the moving block 18, so that the circular ring 7 and the sliding rod 6 will not be damaged, thereby protecting the circular ring 7 and the sliding rod 6.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
