Description

Technical Field

[0001] The invention belongs to the technical field of drilling processing, and specifically refers to a drilling processing device for an assembled laminated plate. Background Art

[0002] Prefabricated composite pressed board is a building component welded by fiber reinforced cement pressure plate, galvanized steel grid, embedded keel on the back and steel truss. Its characteristics include fire resistance, light weight and high strength, and it is favored by the construction industry.

[0003] Prefabricated panels generally require pre-processing of installation holes, and the position accuracy requirements of most installation holes are not high, because there are no matching holes on the building. Prefabricated panels are mainly installed on-site through self-tapping or rivets, expansion bolts, etc.

[0004] However, since there are pre-buried keels and steel bars inside the plate, they need to be avoided when drilling, otherwise it will not only easily damage the drill bit, but once the keel is damaged, it will also affect the overall strength performance of the plate.

[0005] Generally speaking, the movement of the workpiece or tool during drilling is performed manually. Even if it is performed automatically, it requires a more complex position feedback and control system, which is not conducive to reducing production costs and improving promotion value. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a plate drilling processing device capable of automatic transverse movement. This solution is suitable for laminated plates with an even number of keels and roughly evenly distributed (in fact, most laminated plates meet this feature), so as to ensure that the center position of the plate is located between the two middle keels, and then the keel spacing is used as the unit amplitude of transverse movement, so as to ensure that the drilling position can avoid the keel without using ultrasonic detection or other methods; Furthermore, the present invention uses an adaptive braking mechanism and a progressive lateral feed mechanism that cooperate with each other and move alternately. During the drilling process, on the one hand, the position of the hollow slider is locked, and on the other hand, the rack fixing frame is pre-laterally moved a certain distance. After the drilling stops, on the one hand, the position lock of the hollow slider can be automatically released, and on the other hand, the position of the hollow slider can be followed up by the elastic force of the progressive spring.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figure 1 to Figure 12 As shown, the present invention proposes a drilling processing device for an assembled laminated plate, comprising a lateral displacement mechanism 1, an adaptive braking mechanism 2, a progressive lateral feed mechanism 3 and a main body mechanism 4, wherein the lateral displacement mechanism 1 is arranged on the main body mechanism 4, the adaptive braking mechanism 2 is arranged on the lateral displacement mechanism 1, and the progressive lateral feed mechanism 3 is arranged on the adaptive braking mechanism 2.

[0035] The lateral displacement mechanism 1 includes a lifting side plate 5 and an adaptive centering component 6. The lifting side plate 5 is arranged on the main mechanism 4.

The hollow slider 8 is slidably arranged on the elliptical slide bar 7. The centering spring 9 is symmetrically arranged at both ends of the hollow slider 8. The centering spring 9 is arranged between the elliptical slide bar 7 and the hollow slider 8.

[0036] By designing the cross-sectional shape of the elliptical slide bar 7 itself, or by adding an additional guide rod, the hollow slider 8 will not rotate or swing while sliding along the elliptical slide bar 7. By symmetrically arranged centering springs 9, the hollow slider 8 can be automatically centered and reset in the absence of any other external force.

[0037] The adaptive brake mechanism 2 includes a hydraulic chamber assembly 10, a hydraulic generating assembly 11 and a driving assembly 12. The hydraulic chamber assembly 10 is arranged on the lateral displacement mechanism 1, the hydraulic generating assembly 11 is rotatably arranged in the hydraulic chamber assembly 10, and the driving assembly 12 is arranged on the hydraulic chamber assembly 10.

[0038] The adaptive brake mechanism 2 can be used to transmit and drive the liquid. When the drill bit is driven to rotate, the position of the hollow slider 8 is fixed by braking. After the drill bit stops driving, the brake can be automatically released.

[0039] The hydraulic chamber assembly 10 includes a hydraulic cavity 13, a brake block 14 and a brake spring 15. The hydraulic cavity 13 is fixedly connected to the bottom of the hollow slider 8. The hydraulic cavity 13 is composed of a square portion 22, a circular portion 23 and a side balancing joint 24. The bottom of the side balancing joint 24 is provided with a cavity slide groove 25. The brake block 14 is snap-fitted and slidably arranged in the hollow slider 8. A central through hole 26 is provided on the brake block 14. The elliptical slide rod 7 is located inside the central through hole 26. One end of the brake spring 15 is arranged at the bottom of the square portion 22, and the other end of the brake spring 15 is arranged on the brake block 14.

[0040] The hydraulic generating assembly 11 includes a central spindle 16, a hydraulic wheel 17 and a balancing piston 18. The central spindle 16 is rotatably arranged in the hydraulic cavity 13. A drill quick-release joint 27 is provided at the bottom of the central spindle 16. The hydraulic wheel 17 is arranged on the central spindle 16. The hydraulic wheel 17 is located in the circular portion 23. The balancing piston 18 is slidably engaged in the side balancing joint 24.

[0041] When the central main shaft 16 rotates, it can drive the liquid to flow through the hydraulic wheel 17, thereby driving the brake block 14 to rise or fall. The brake block 14 can fix the position of the hollow slider 8 when moving in two directions.

[0042] The driving assembly 12 includes a rotating motor 19, a driving gear 20 and a driven gear 21. The rotating motor 19 is arranged on the square portion 22, the driving gear 20 is arranged on the output shaft of the rotating motor 19, and the driven gear 21 is arranged on the central main shaft 16. The driving gear 20 and the driven gear 21 are meshed for transmission.

[0043] The progressive lateral feed mechanism 3 includes a progressive amplitude adjustment component 28, a progressive reset component 29, a progressive guide component 30 and a manual unlocking component 31. The progressive amplitude adjustment component 28 is slidably arranged on the hydraulic chamber component 10, the progressive reset component 29 is arranged on the progressive amplitude adjustment component 28, the manual unlocking component 31 is arranged on the lateral displacement mechanism 1, and the progressive guide component 30 is arranged in the manual unlocking component 31.

[0044] Through the transmission of the progressive transverse feed mechanism 3, the position of the hollow slider 8 can be adaptively moved transversely during the intermittent rotation of the central spindle 16. Moreover, the unit distance of each transverse movement can be calibrated by manual adjustment in advance. Since the keel portion 47 is set at intervals and the distance of each transverse movement is basically the same, it can be ensured that the drilling position can avoid the keel portion 47.

[0045] The progressive amplitude adjustment component 28 includes a rack fixing frame 32, a rack body 33 and an adjusting top screw 34. The rack fixing frame 32 is slidably engaged in the cavity slide groove 25. A threaded hole 42 is provided on the rack fixing frame 32. The adjusting top screw 34 and the threaded hole 42 are threadedly connected. The rack body 33 is slidably engaged in the rack fixing frame 32. The rack body 33 and the driven gear 21 are meshed for transmission. The rack body 33 and the rack fixing frame 32 are locked in position by the adjusting top screw 34. Arc-shaped stop notches 43 are provided at both ends of the rack body 33.

[0046] The progressive reset assembly 29 includes an L-shaped spring bracket 35 and a progressive spring 36 . The L-shaped spring bracket 35 is fixed to both ends of the rack fixing bracket 32 ​​. The progressive spring 36 is arranged between the L-shaped spring bracket 35 and the side balance joint 24 .

[0047] The manual unlocking assembly 31 includes a crossbeam holder 40 and a crossbeam return spring 41 . The crossbeam holder 40 is fixedly connected to the lifting side plate 5 , and the crossbeam return spring 41 is disposed in the crossbeam holder 40 .

[0048] The progressive guide assembly 30 includes a U-shaped beam 37, a short ratchet plate 38 and a long ratchet plate 39. The U-shaped beam 37 is arranged on the beam return spring 41. The U-shaped beam 37 is slidably engaged in the beam holder 40. A bottom handle 44 is provided at the bottom of the U-shaped beam 37. The short ratchet plate 38 is fixedly connected to the bottom of the rack fixing frame 32. The long ratchet plate 39 is fixedly connected to the U-shaped beam 37. The short ratchet plate 38 and the long ratchet plate 39 are matched by ratchets.

[0049] The main body 4 includes a base plate 45, a workpiece body 46 and a drill body 48. The lifting side plate 5 is arranged on the base plate 45. The workpiece body 46 is detachably arranged on the base plate 45. A keel part 47 is arranged inside the workpiece body 46. The drill body 48 is detachably arranged on the drill quick-release joint 27.

[0050] The drill body 48 may be provided with bidirectional threads, so that the drill body 48 has a good drilling effect when rotating in different directions, or the drill body 48 with different thread directions can be replaced when rotating in different directions.

[0051] During specific use, the user first needs to fix the workpiece body 46. Since the number of keels 47 is an even number, there must be no keel 47 at the center position of the workpiece body 46. Therefore, in the initial state, by pulling down the bottom handle 44, the short ratchet plate 38 and the long ratchet plate 39 can be temporarily separated. At this time, the hollow slider 8 automatically resets to the center position of the elliptical slide rod 7 under the elastic force of the centering spring 9. At this time, the bottom of the drill body 48 is exactly the center of the two keels 47, and this position will be used as the initial position for subsequent drilling.

[0052] Then, the rotating motor 19 is started, and the central spindle 16 is rotated through the transmission between the driving gear 20 and the driven gear 21. When the central spindle 16 rotates, it pushes the liquid in the hydraulic cavity 13 to flow through the hydraulic wheel 17. At this time, whether the brake block 14 rises or falls, the position of the hollow slider 8 can be fixed by squeezing between itself and the elliptical slide bar 7; At the same time, due to the meshing transmission between the driven gear 21 and the rack body 33, the rack body 33 will slide laterally along the cavity slide groove 25 together with the rack fixing frame 32 until the driven gear 21 reaches the arc-shaped stop notch 43, and the rack body 33 will stop sliding and remain at the current position during the continuous rotation of the driven gear 21; Then, the lifting side plate 5 is lifted and lowered with the drill body 48 as a whole, and the rotating drill body 48 can drill the workpiece body 46 when it descends. After the drill body 48 has finished drilling and has risen and reset, the rotating motor 19 is turned off, and the central spindle 16 also loses the driving force for rotation. At this time, the brake block 14 is reset under the elastic force of the brake spring 15, so that the inner wall of the central through hole 26 is separated from the elliptical slide bar 7; After the position lock of the hollow slider 8 is released, the hydraulic cavity 13 will slide with the hollow slider 8 to the middle position of the progressive spring 36 under the elastic force of the progressive spring 36. Since the elastic modulus of the progressive spring 36 is much larger than the elastic modulus of the centering spring 9, the progressive spring 36 occupies a dominant position in the process of the hollow slider 8 sliding toward one side. In this case, although the amplitude of each sliding will gradually become smaller, the accumulated error is far from enough to make the drill body 48 stop above the keel part 47.

[0053] Since the short ratchet plate 38 and the long ratchet plate 39 are matched with each other through ratchet teeth, the short ratchet plate 38 can only slide in one direction relative to the long ratchet plate 39. Therefore, when the central spindle 16 rotates periodically, the hollow slider 8 will also slide periodically, which is specifically manifested as follows: when the rotating motor 19 is started, the position of the hollow slider 8 is locked and the rack fixing frame 32 is pushed a certain distance; after the drill body 48 completes the drilling, the rotating motor 19 is turned off, and after the position lock of the hollow slider 8 is released, the hollow slider 8 and the hydraulic cavity 13 will follow their own positions.

[0054] After the hole processing on one side is completed, the short ratchet plate 38 and the long ratchet plate 39 can be temporarily separated by pulling down the bottom handle 44. At this time, the hollow slider 8 is automatically reset to the center position of the elliptical slider 7 under the elastic force of the centering spring 9, and then the rotary motor 19 is started in the reverse direction to drill holes on the other side in sequence. The drill bit body 48 may be designed with a bidirectional thread, so that a good drilling effect can be achieved regardless of the rotation direction of the drill bit body 48; The drill body 48 can also be quickly disassembled and assembled through the drill quick-release joint 27. When changing the rotation direction, it is sufficient to replace the drill body 48 with the opposite direction of the thread groove.

[0055] The relative positions of the rack fixing frame 32 and the rack body 33 can be locked by adjusting the top screw 34 , and the amplitude of each lateral movement of the hollow slider 8 can be manually preset by adjusting the position of the rack body 33 in the rack fixing frame 32 .

[0056] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0057] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
