Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to a stone plate punching device. Background Art

[0002] As a high-end building decoration material, stone is widely used in interior and exterior decoration design, curtain wall decoration and public facilities construction. At present, the common stones on the market are mainly divided into natural stone, artificial stone and marble. Natural stone is divided into slate and granite according to its physical and chemical properties. With the development of architectural design, stone has long become one of the important raw materials for construction, decoration, road and bridge construction. During the processing of stone, a drilling device is needed to drill holes on the surface of the stone. The stone needs to be fixed during drilling to prevent it from vibrating and shifting, which affects the drilling accuracy.

[0003] Chinese patent application number CN219806310U discloses a building construction leveling device comprising a positioning mechanism with a drilling mechanism externally mounted thereon. The positioning mechanism comprises a support platform with a threaded rod internally mounted on the upper end of the support platform. A guide block is threadedly connected to the rod externally, and a push plate is fixedly connected to the upper end of the guide block. An annular pressure plate is mounted on the upper portion of the support platform. This stone processing drilling device utilizes an annular pressure plate to drive the threaded rod to rotate, which in turn drives the guide block to move horizontally along the longitudinal direction of the support platform, thereby causing the two guide blocks to drive the push plate to move horizontally along the longitudinal direction.

[0004] However, the above has the following shortcomings:

[0005] 1. According to the description in the above patent, the drilling device can move horizontally only through the linkage of the linear drive guide rail and the electric telescopic rod. However, when drilling stone slabs, slots are sometimes required. When the drill bit moves, the above device needs to be lifted due to the clamping device. At this time, the clamping device is ineffective, resulting in the stone slab being drilled without being clamped, causing the stone slab to shake and resulting in poor slot shape.

[0006] 2. The above patent does not provide a stable device for the drill bit, which causes the drill bit to be in contact with the stone slab and be offset during drilling, resulting in the hole being slanted, resulting in poor shape of the drilled hole and even the stone slab being scrapped, requiring the drill bit to be re-drilled, which not only wastes the stone slab but also reduces work efficiency. Utility Model Content

[0007] In order to overcome the deficiencies of the prior art, the utility model solves the technical problem of adding a translation pulley to the pressing device so that the punching device can maintain pressure on the punching surface when moving horizontally, so that the shape of the slot hole is stable. At the same time, by supporting and fixing the four corners of the drill bit, the drill bit can be stably pointed downward when punching, so that the punched holes are vertical and well-shaped, thereby avoiding waste of raw materials and improving work efficiency.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a stone plate punching device, comprising a shell and a fixed shell, characterized in that two connecting plates are symmetrically distributed and fixedly connected outside the fixed shell, two rotating shafts are symmetrically distributed and rotatably connected between the two connecting plates, a pulley is fixedly connected to the surface of each rotating shaft, two movable belts are connected for transmission around the surfaces of the two pulleys, a pressure plate is fixedly connected between the two connecting plates, an avoidance groove is provided at the center of the pressure plate, and the two movable belts are respectively located on both sides of the pressure plate avoidance groove, and also includes a movable platform, the movable platform is movably connected to the bottom of the shell, the fixed shell is movably connected in the shell, and a drilling mechanism is provided in the fixed shell.

[0009] Furthermore, the drilling mechanism includes a movable plate 2, a plurality of lead screws 3 symmetrically distributed and rotatably connected in the fixed shell, the lead screws 3 are transmission-connected to the movable plate 2, a drill shaft is rotatably connected at the center of the movable plate 2, and a drill bit is fixedly connected to the lower end of the drill shaft.

[0010] Furthermore, the surface of the fixed shell is fixedly connected to a first motor at each lead screw three, an avoidance groove is provided at the center of the upper end of the fixed shell, the upper end of the movable plate two is fixedly connected to a gear box, the upper end of the gear box is fixedly connected to a second motor, each of the first motor transmission ends is transmission-connected to the corresponding lead screw three, the second motor transmission end is transmission-connected to the gear box power input end, and the gear box power output end is transmission-connected to the drill bit shaft.

[0011] Furthermore, the upper end of the fixed shell is fixedly connected to a connecting shell 1, the upper end of the connecting shell 1 is fixedly connected to the telescopic end of the cylinder, the cylinder body is fixedly connected to a moving block 1, the surface of the cylinder body is symmetrically distributed and fixedly connected to the limiting blocks, the surface of the connecting shell 1 is symmetrically distributed and fixedly connected to the support plates, each of the support plates is fixedly connected to a sliding rod on the upper end, and the sliding rod is slidably connected to the limiting blocks.

[0012] Furthermore, the upper end of the movable platform is fixedly connected to a clamping platform, and fixed plates are symmetrically distributed and fixedly connected on both sides of the clamping platform.

[0014] In summary, compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The moving belt is linked to the pressing plate so that when there is a slot requirement for punching, the punching device can press and move at the same time, so that the stone plate can be punched while being pressed, and the stone plate will not shake, making the shape of the slot stable.

[0016] (2) Due to the use of a screw drive, the four corners of the drill bit's moving block are supported, so that the drill bit can maintain a stable downward movement during drilling, so that the holes drilled will not be tilted, thus avoiding the waste of stone slabs and improving work efficiency. At the same time, due to the characteristics of the screw, the drill bit can be locked in a fixed position. When the stone slab requires a slot, the drill bit can be stabilized at the same depth, and the slotting operation can be completed in one go, thereby improving work efficiency.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1:

[0025] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, a stone plate punching device includes a shell 10, the lower end of the shell 10 is rotatably connected to the screw 23, the surface of the shell 10 is fixedly connected to the third motor 33 at the corresponding position of the screw 23, the transmission end of the third motor 33 is transmission-connected to the screw 2 23, the surface of the screw 12 is transmission-connected to the moving block 11, the surface of the screw 23 is transmission-connected to the moving platform 38, the upper end of the moving platform 38 is fixedly connected to the clamping platform 22, two fixed plates 24 are symmetrically distributed and fixedly connected on both sides of the clamping platform 22, a plurality of springs 25 are linearly distributed and fixedly connected on one side of a fixed plate 24, and one end of the spring 25 is fixedly connected to the moving plate 1 26.

[0026] A spring 25 is provided to be linked with the movable plate 1 26 so that the stone plate can be fixed on the clamping platform 22. The third motor 33 drives the screw 23 to rotate so that the movable platform 38 slides, so that the stone plate fixed on the surface of the clamping platform 22 on the movable platform 38 can be displaced along the axial direction of the screw 2 23.

[0027] like Figure 3 and Figure 4As shown, a fixed shell 19 is movably connected inside the shell 10, and an avoidance groove is provided on the surface of the fixed shell 19. Two groups of symmetrical lead screws 31 are symmetrically distributed and rotatably connected inside the fixed shell 19. A first motor 18 is fixedly connected to the surface of the fixed shell 19 at a corresponding position of each lead screw 31. The transmission end of the first motor 18 is transmission-connected to the lead screw 31, and the surface of the four lead screws 31 is transmission-connected to a movable plate 2 32. The center of the movable plate 2 32 is rotationally connected to a drill shaft 29, and a drill bit 30 is fixedly connected to the lower end of the drill shaft 29. The upper end of the movable plate 2 32 is fixedly connected to a gear box 28, and the upper end of the gear box 28 is fixedly connected to a second motor 27. The transmission end of the second motor 27 is transmission-connected to the power input end of the gear box 28, and the power output end of the gear box 28 is transmission-connected to the drill shaft 29.

[0028] Multiple lead screws 31 are provided so that the movable plate 2 32 is subjected to multiple supporting forces, so that the movable plate 2 32 remains stable and can be locked at any time when moving up and down. As the movable plate 2 32 moves, the drill bit 30 connected to the movable plate 2 32 moves, so that the drill bit 30 can drill downward stably under the action of the movable plate 2 32.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, the upper end of the fixed shell 19 is fixedly connected to the connecting shell 17, the upper end of the connecting shell 17 is fixedly connected to the telescopic end of the cylinder 13, the cylinder body of the cylinder 13 is fixedly connected to the moving block 11, the surface of the cylinder 13 is symmetrically distributed and fixedly connected with two limit blocks 14, the surface of the connecting shell 17 is symmetrically distributed and fixedly connected with two connecting shells 17, the support plate 16 is fixedly connected with the sliding rod 15, and the sliding rod 15 is slidably connected to the limit block 14.

[0030] The cylinder 13 pushes the connecting shell 17 so that the fixed shell 19 can move up and down. Because the limit block 14 limits the sliding direction of the slide rod 15, the cylinder 13 is restricted and will not deflect.

[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, a screw 12 is rotatably connected inside the housing 10, a fourth motor 37 is fixedly connected to the surface of the housing 10, a transmission end of the fourth motor 37 is transmission-connected to the screw 12, a moving block 11 is transmission-connected to the surface of the screw 12, and the screw 12 and the screw 2 23 are vertically distributed.

[0032] Screw 12 and screw 2 23 are provided and are vertically distributed, so that the drill bit 30 can drill holes at any position of the stone slab.

[0033] like Figure 4 and Figure 5As shown, a drilled avoidance groove is provided at the center of the lower end of the fixed shell 19, and a connecting plate 20 is symmetrically distributed and fixedly connected on the lower surface of the fixed shell 19. Two rotating shafts 21 are symmetrically distributed and rotatably connected between the two connecting plates 20. A pulley 35 is fixedly connected to the surface of each rotating shaft 21, and two movable belts 34 are symmetrically distributed on the surfaces of the two pulleys 35 for transmission connection. The two connecting plates 20 are located between the two rotating shafts 21 and are fixedly connected to a pressure plate 36. A drilled avoidance groove consistent with the lower end of the fixed shell 19 is opened at the center of the pressure plate 36, and the movable belts 34 are symmetrically distributed on both sides of the avoidance hole of the pressure plate 36.

[0034] The pulley 35 and the pressure plate 36 are linked together so that when the grooves are punched, the pulley 35 and the pressure plate 36 can be pressed tightly at all times, so that the moving belt 34 fits tightly with the punching surface of the stone slab, so that the stone slab will not shake due to lack of pressure, and the punched grooves have good shapes.

[0035] In this embodiment, initially, the movable platform 38 is at the farthest transmission end of the screw 23, the movable block 11 is at the near transmission end of the screw 12 located in the housing 10, the cylinder 13 is in a tightened state, the limit block 14 is in contact with the support plate 16, the movable plate 2 32 is at the top end of the fixed shell 19, and the spring 25 is in an extended state.

[0036] Before use, the operator connects the device to the power supply and places the stone plate on the surface of the clamping platform 22. At this time, due to the large width of the stone plate, the movable plate 26 is pushed close to the adjacent fixed plate 24, and the spring 25 is compressed and accumulates elasticity, so that the stone plate is fixed under the joint action of the spring 25 and the movable plate 26. At this time, the operator confirms the position where the hole needs to be punched.

[0037] Before drilling, the operator turns on the third motor 33. Since the third motor 33 drives the screw 23 to rotate, the mobile platform 38 connected to the screw 23 slides along the axis of the screw 23, so that the drilling position is horizontally aligned with the drill bit 30. At this time, the fourth motor 37 is turned on to drive the screw 12 to rotate, so that the moving block 11 connected to the screw 12 slides horizontally, so that the screw 23 connected to the lower end of the moving block 11 and the connecting shell 17 connected to the lower end of the screw 23 slide horizontally, so that the fixed shell 19 at the lower end of the connecting shell 17 and the moving plate 2 32 inside the fixed shell 19 slide horizontally, so that the drill bit 30 fixed on the moving plate 2 32 is aligned with the drilling position.

[0038] When pressing, the driving cylinder 13 pushes the connecting shell 17 downward, so that the fixed shell 19 and the movable plate 2 32 and the drill bit 30 in the fixed shell 19 are pressed downward. Since the limit block 14 limits the sliding direction of the slide rod 15, the pushing direction of the cylinder 13 is consistent with the sliding direction of the slide rod 15 under the restriction of the limit block 14, and no deflection occurs. Since the fixed shell 19 is pressed downward, the connecting plates 20 on both sides of the fixed shell 19 are pressed downward, so that the moving belt 34 on the surface of the pulley 35 between the connecting plates 20 is tightly fitted with the punching surface of the stone plate under the extrusion of the pulley 35 and the pressure plate 36.

[0039] When drilling, the first motor 18 is turned on at the same frequency to drive the screw three 31 to rotate, so that the movable plate two 32 connected to the screw three 31 moves downward stably, and the second motor 27 drives the drill shaft 29 to rotate through the gear box 28, so that the drill bit 30 fixed to the drill shaft 29 rotates at high speed. When the movable plate two 32 is pressed down by the screw three 31, the drilling end of the drill bit 30 connected to the movable plate two 32 fits the punching surface of the stone plate, the movable plate two 32 continues to be pressed down under the drive of the screw three 31, and the drill bit 30 generates an upward reaction force due to the downward pressure and drilling. Since the four corners of the movable plate two 32 are restricted by the screw three 31, no deviation occurs, so that the drill bit 30 continues to move downward stably, and the holes punched are straight without skew.

[0040] After the drilling is completed, the first motor 18 drives the lead screw 31 to reverse at the same frequency, so that the movable plate 2 32 drives the drill bit 30 to move upward, and the drill bit 30 returns straight to the inside of the fixed shell 19 along the drilling direction. The second motor 27 is turned off to stop the drill bit 30 from rotating, and the cylinder 13 pulls the connecting shell 17 to move upward, so that the fixed shell 19 connected to the connecting shell 17 drives the connecting plate 20 on the surface of the fixed shell 19 to move upward, so that the moving belt 34 leaves the surface of the stone slab. Then, the third motor 33 and the fourth motor 37 drive the lead screw 2 23 and the lead screw 12 to reverse respectively, so that the moving block 11 and the moving platform 38 return to their initial positions. The operator removes the stone slab with holes from between the movable plate 1 26 and the relative fixed plate 24, completing the stone slab drilling operation. Example 2:

[0041] Since there will be a need for slots when drilling holes in stone slabs, if the above operation is performed directly for slotting, the slot shape will be poor, so the following operation is performed.

[0042] Before use, when marking the drilling position, you need to mark the starting point, route, and end point of the slot.

[0043] During drilling, after the drill bit 30 completes drilling the vertical hole at the starting position of the slot in the stone plate, the fourth motor 37 drives the lead screw 12 to rotate, so that the moving block 11 moves along the drilling path, so that the moving block 11 drives the connecting shell 17 connected to the cylinder 13 to move, so that the connecting shell 17 drives the fixed shell 19 and the connecting plate 20 outside the fixed shell 19 to move horizontally.

[0044] When the connecting plate 20 moves, the moving belt 34 is in close contact with the surface of the stone slab. Since the moving belt 34 is connected to the pulley 35 for transmission, the moving belt 34 runs along the surface of the stone slab, and when the moving belt 34 moves, the moving belt 34 will not slide relative to the surface of the stone slab.

[0045] When the fixed shell 19 drives the movable plate 2 32 and the drill bit 30 to move, due to the nature of the screw 31, the movable plate 2 32 remains stably fixed in the horizontal direction, so that the drill bit 30 will not deflect due to the movement until the drill bit 30 moves to the end position, so that the slot hole drilled by the drill bit 30 after movement has a good shape, avoiding the waste of stone slabs caused by poor drilling and improving work efficiency.

[0046] The first motor 18 , the second motor 27 , the gearbox 28 , the third motor 33 , and the fourth motor 37 are all mature existing technologies and will not be described in detail herein.
