Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a stone surface inspection device. Background Technology

[0002] Stone is a high-end building decoration material widely used in interior and exterior decoration design, curtain wall decoration and public facility construction. The most common types of stone on the market are natural stone and artificial stone.

[0003] During stone processing, stone needs to be cut into different specifications, requiring further cutting. The flatness of the cut stone surface often needs to be inspected, necessitating the use of a testing device. For example, utility model CN220136263U discloses a surface inspection device for cut stone, comprising a testing platform. A connecting block is fixedly connected to the bottom of the testing platform, a cylinder is fixedly connected to one side of the connecting block, a moving block is fixedly connected to the output end of the cylinder, a support plate is fixedly connected to the top of the moving block, a limit frame is fixedly connected to the front of the support plate, a sliding seat is slidably connected inside the limit frame, a guide rod is slidably connected inside the sliding seat, and a testing head is fixedly connected to one end of the guide rod. Through the cooperation of the cylinder, moving block, support plate, and limit frame, the limit frame can be moved back and forth, up and down, facilitating the flatness inspection of cut stone of different sizes.

[0004] However, the testing device in the above application can only test one side of the stone during the stone testing process. When it is necessary to test different sides of the stone, the operator needs to repeatedly adjust the fixed position of the stone, which affects the testing efficiency. Therefore, a stone surface testing device is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1-4 As shown, the present invention proposes a stone surface testing device, including a testing table 1, on which a testing component 2 for stone testing is provided;

[0031] The middle part of the testing table 1 is equipped with a fastener 3 for fixing the stone.

[0032] In this invention, the testing component 2 on the testing table 1 can test both sides of the stone at once, and can also automatically adjust the testing surface to improve the testing efficiency of the stone surface flatness.

[0033] It should be noted that the fixing component 3 includes two abutments 31 that are symmetrically slidably connected to the upper surface of the testing table 1. Two symmetrically distributed stops 32 are fixedly connected to the upper surface of the testing table 1 and located behind the abutments 31. The lower end of each abutment 31 is fixedly connected to a connecting rod 36 that penetrates the testing table 1. The lower ends of the two connecting rods 36 are fixedly connected to threaded blocks 34. The lower surface of the testing table 1 is fixedly connected to an installation block 33, and the front side of the installation block 33 is rotatably connected to a rotating screw 35 that penetrates the threaded block 34. By rotating the rotating screw 35, the abutment 31 is driven to approach the stop 32, which can stably clamp the stone to be tested.

[0034] The threaded block 34 has a second threaded hole in the middle, which is compatible with the thread on the outside of the rotating screw 35. The thread on the outside of the rotating screw 35 is a triangular thread. The test table 1 has a through hole for the connecting rod 36 to move, so that the connecting rod 36 passing through the test table 1 has space to move back and forth. By rotating the rotating screw 35, the threaded block 34 and the connecting rod 36 can be used to move the stop block 31 towards the side closer to or away from the stop block 32 for adjustment.

[0035] In an optional embodiment, the detection element 2 includes a rotating ring 22. The detection table 1 has an annular support groove 21 for the rotating ring 22 to rotate. The rotating ring 22 is rotatably connected in the support groove 21. A bracket 24 is fixedly connected to the rotating ring 22. An electric push rod 25 is fixedly installed at the upper end of the bracket 24. The output end of the electric push rod 25 passes through the bracket 24. A connecting frame 26 is fixedly connected to the output end of the electric push rod 25. A servo motor 214 is fixedly connected to one end of the connecting frame 26. An adjusting screw 29 is rotatably connected to the output shaft of the servo motor 214. Two symmetrically distributed support plates 210 are threaded onto the adjusting screw 29. A support rod 211 that passes through the support plate 210 is slidably connected to the lower end of each support plate 210. A detection head 212 is fixedly connected to one end of the support rod 211 that passes through the support plate 210. A spring 213 is fixedly connected between each detection head 212 and the support plate 210.

[0036] The upper end of the support rod 211 is equipped with a drawing pen 215 for recording flatness; the front and rear sides of the bracket 24 are both fixedly installed with a placement plate 4 for placing paper for recording flatness.

[0037] It should be noted that the back of the testing table 1 and the rotating ring 22 are provided with a drive assembly for driving the rotating ring 22 to rotate axially. The drive assembly includes a rack 23 fixedly connected to the outer surface of the rotating ring 22. A drive motor 27 is fixedly installed on the back of the testing table 1, and the output shaft of the drive motor 27 is fixedly connected to a gear 28 that meshes with the rack 23. After the start-up drive motor 27 drives the gear 28 to rotate axially through the rotating gear 28, it can drive the rotating ring 22 to rotate axially stably within the support groove 21 of the testing table 1.

[0038] In this embodiment, by lowering and bringing the two detection heads 212 closer together, both sides of the stone can be detected simultaneously. At the same time, the rotation of the detection heads 212 is adjusted by the rotating ring 22, so that the surface of the stone being detected can be adjusted, so that the stone does not need to be frequently adjusted and fixed during the detection process, thereby improving the detection efficiency.

[0039] The upper end of the support plate 210 is provided with a first threaded hole, which is adapted to the thread on the outside of the adjusting screw 29. The thread on the outside of the adjusting screw 29 is in two sections and the two sections are symmetrically distributed, so that the adjusting screw 29 driven by the servo motor 214 can drive the two support plates 210 to move and adjust towards one side that is closer to or away from each other.

[0040] In addition, the upper end of the support rod 211 is L-shaped, and its end is provided with a placement groove for placing the drawing pen 215. The upper end of the support rod 211 is threadedly connected to a fixing screw 216 that passes through and extends into the placement groove. The upper end of the support rod 211 is also provided with a third threaded hole for the fixing screw 216 to rotate, so that the fixing screw 216, which is rotated and screwed into the placement groove, can fix the drawing pen 215 placed in the placement groove.

[0041] The two support rods 211L have opposite ends, so that the upper ends of the two support rods 211 can face the staggered placement plates 4 respectively; rectangular slots for pulling the support rods 211 are provided on both the left and right sides of the bracket 24, so that the operator can pull the support rods 211 out of the bracket 24 through the rectangular slots to disassemble and assemble the drawing pen 215 at the end of the support rods 211.

[0042] In an optional embodiment, two placement plates 4 are symmetrically distributed on the front and rear sides of the support 24 with a left-right offset. A placement rack 5 is fixedly connected to the side of the placement plate 4 closest to the support 24. The placement rack 5 is L-shaped and has a groove on its inner side. A pull rod 6 that passes through the placement plate 4 is slidably connected to the side of the placement plate 4 away from the support 24. A clamping block 7 is fixedly connected to one end of the pull rod 6 that passes through the placement plate 4. Magnet blocks 8 are embedded in both the side of the clamping block 7 closest to the placement plate 4 and the side of the placement plate 4 closest to the clamping block 7.

[0043] In this embodiment, the L-shaped shelf 5 can be used to place the paper for drawing lines. Pulling the lever 6 causes the clamping block 7 to be attracted by the magnet block 8, which can clamp and fix the paper. At the same time, pushing the lever 6 can also easily remove the paper after the lines have been drawn.

[0044] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Since this utility model is mainly used to protect mechanical structures, the control method and circuit connection and other technical means will not be described in detail here.

[0045] The working principle in the above embodiments is as follows:

[0046] Pulling the lever 6 causes the clamping block 7 to be attracted by the magnet block 8, which can clamp and fix the placed paper. Then, pull out the support rod 211 from the bracket 24 through the rectangular groove. Place the drawing pen 215 in the placement groove at the upper end of the support rod 211. Hold the drawing pen 215 and the reset support rod 211, and after the drawing end of the drawing pen 215 is in contact with the paper, tighten the fixing screw 216 to fix the drawing pen 215.

[0047] Then, after placing the square stone to be tested vertically between the two abutments 31 and the stop block 32, the screw 35 can be rotated in conjunction with the threaded block 34 to move the abutment 31 on the connecting rod 36 toward the side closer to the stop block 32, thereby fixing the placed stone.

[0048] Then, the electric push rod 25 is activated to lower the connecting frame 26, causing the detection head 212 to be flush with the upper side of the stone. Then, the servo motor 214 is activated to drive the detection head 212 on the support plate 210 to be tightly attached to the left and right sides of the stone by the spring 213 through the adjusting screw 29. Then, the electric push rod 25 is activated to continue to lower the connecting frame 26, thereby causing the detection head 212 to move down along with the side plate of the stone. During the downward movement of the detection head 212, the drawing pen 215 at the upper end of the support rod 211 will slide out numerical lines on the paper. When the stone detection surface is uneven, the lines drawn by the drawing pen 215 will be wavy, indicating that the detection surface is not flat.

[0049] After the left and right sides of the stone have been inspected, the inspection head 212 can be reset. Then, the drive motor 27 is started, which drives the rotating ring 22 and the bracket 24 to rotate counterclockwise by 90 degrees through the meshing gear 28 and rack 23, so that the two inspection heads 212 face the front and back sides of the stone. The above inspection steps are repeated to inspect the flatness of the front and back sides of the stone. When it is necessary to inspect all six sides of a square stone, the stone is loosened, rotated 90 degrees, and then fixed again to inspect the top and bottom sides of the stone.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
