Description

Technical Field

[0001] The present application relates to the field of drill bits, and in particular to a drill bit structure. Background Art

[0002] As the name suggests, a drill bit is a tool for drilling holes. The drill bit is usually cooperated with the telescopic rotating structure on the vehicle body to drill holes in the ground or other places where holes need to be drilled. The telescopic rotating structure usually refers to the combination of a telescopic part and a motor. The drill bit structure in the related art can only utilize the telescopic rotating structure to drive it to drill up and down. It lacks a quick docking structure for tilt adjustment and fixation. It is not possible to quickly deflect and fix the drill bit at an angle when tilt drilling is required, which is not conducive to the promotion and use of the drill bit structure. Summary of the invention

[0003] In order to make up for the above shortcomings, the present application provides a drill bit structure, aiming to improve the problem that the drill bit structure in the related art lacks a quick docking structure for tilt adjustment and fixation.

[0004] An embodiment of the present application provides a drill bit structure, including a drill bit connection assembly and a drill bit assembly.

[0005] The drill bit connection assembly includes a rectangular plate and two fixed plates and two connection plates I. The two fixed plates and the two connection plates I are respectively arranged on both sides of the rectangular plate. A connection tube is commonly connected between the two connection plates I. A connection piece is arranged in the connection tube, and the two ends of the connection piece are movably extended out of the two ends of the connection tube. The two connection plates I are also provided with connection holes I distributed around the axis of the connection tube at equal intervals.

[0006] The drill bit assembly includes a telescopic rotating part, a drill bit and two connecting plates II. The drill bit and the two connecting plates II are respectively arranged at the two ends of the telescopic rotating part. The opposite surfaces of the two connecting plates II are respectively fitted with the separated surfaces of the two connecting plates I. The two connecting plates II are both penetrated by a through hole corresponding to the connecting tube. The docking piece can be movably inserted into the through hole and continue to extend outward. The separated sides of the two connecting plates II are also equipped with a plurality of connectors corresponding to each of the docking holes I, and the two connecting plates II and the two connecting plates I can be adjustably fixed with the help of the connectors.

[0007] In the above implementation process, first press the plug sleeves at both ends into the inner cavity of the connecting cylinder, and then slowly push the opposite surfaces of the two connecting plates II to the separated surfaces of the two connecting plates I. When the through holes opened on the plug sleeve and the connecting plate II are aligned, the spring I will restore its elasticity to drive the plug sleeve to insert into the through hole, thereby indirectly completing the preliminary installation of the drill bit. Then, according to the direction that the drill bit needs to be adjusted, rotate the drill bit so that the docking hole II on the connecting plate II is aligned with the corresponding docking hole I on the connecting plate I. After alignment, pull the two ends of the pull rod outward so that the spring II is in an extended state, and then insert the positioning rod into the corresponding docking hole II and docking hole I, thereby indirectly completing the adjustment and fixation of the drill bit. To sum up, the present application is not only convenient for stretching and adjusting the drill bit, but also convenient for tilting and adjusting and fixing the drill bit at multiple angles. During the operation of adjustment and fixation, no external tools are needed, which increases the convenience of tilting adjustment of the drill bit.

[0008] In a specific implementation scheme, the two fixing plates are parallel to each other and are respectively connected to both sides of one surface of the rectangular plate by welding. The fixing plates and the rectangular plate are perpendicular to each other. The two fixing plates have the same specifications and are both provided with mounting holes in pairs. And a circular ring sleeve is also welded and fixed in each mounting hole.

[0009] In the above implementation process, the matching setting of the mounting holes and the circular ring sleeves on the fixing plates facilitates the firm installation of the fixing plates and the external bearing equipment.

[0010] In a specific implementation scheme, reinforcing plates are also welded and fixed in pairs on the opposite surfaces of the two fixing plates, and one side of each of the two reinforcing plates is welded and fixed to the rectangular plate.

[0011] In the above implementation process, the setting of the reinforcing plates can increase the connection stability between the two fixing plates and the rectangular plate, and indirectly improve the stability of the overall structure of the device.

[0012] In a specific implementation scheme, the two connecting plates I are parallel to each other and are also respectively connected to the other surface of the rectangular plate by welding, and are located near the other two sides of the rectangular plate. The connecting plate I and the rectangular plate are perpendicular to each other.

[0013] In the above implementation process, the welding fixing method can increase the connection stability between the connecting plate I and the rectangular plate, and also indirectly improve the stability of the overall structure of the device.

[0014] In a specific implementation scheme, the docking member includes an intermediate rod, two plug sleeves and a connecting ring. The outer ring of the connecting ring is fixedly welded to the middle part of the inner wall of the connecting cylinder, and they are coaxially arranged.

[0015] In a specific embodiment, the middle rod is inserted and fixed into the inner ring of the connecting ring, and both ends of the middle rod are slidably sleeved with two of the insertion sleeves. Spring I is fixedly connected to the inner ends of the two insertion sleeves and the outer end of the middle rod.

[0016] In a specific embodiment, the insertion sleeve is movably inserted into the through hole by the driving force of Spring I, and the outer diameter of the insertion sleeve is the same as the inner diameter of the through hole.

[0017] In the above implementation process, the insertion sleeves at both ends are pressed towards the inner cavity of the connecting cylinder, and then the opposite surfaces of the two connecting plates II are slowly pushed towards the separated surfaces of the two connecting plates I. When the through holes opened on the insertion sleeve and the connecting plate II are aligned, Spring I will restore its elasticity to drive the insertion sleeve to insert into the through hole, thereby indirectly completing the preliminary installation of the drill bit.

[0018] In a specific embodiment, the connecting plate II is also provided with docking holes II that are equally spaced and have the same aperture as the docking holes I. The number of the insertion members is the same as that of the docking holes II and they are arranged in one-to-one correspondence.

[0019] In a specific embodiment, all the insertion members include a positioning rod, a pull rod, and two Spring II. The positioning rod is inserted and fixed into the corresponding docking hole II and docking hole I, and one end of the positioning rod is fixed to the central part of the pull rod. One end of each of the two Spring II is connected to the pull rod and is symmetrically arranged with respect to the positioning rod. The other ends of the two Spring II are fixedly connected to the connecting plate II.

[0020] In the above implementation process, according to the direction in which the drill bit needs to be adjusted, the drill bit is rotated so that the docking holes II on the connecting plate II are aligned with the corresponding docking holes I on the connecting plate I. After alignment, the two ends of the pull rod are pulled outwards so that Spring II is in a stretched state, and then the positioning rod is inserted into the corresponding docking hole II and docking hole I, thereby indirectly completing the adjustment and fixation of the drill bit. When the positioning rod is not needed, the positioning rod can be pulled out to the outside of the corresponding hole and its end is abutted against the outside of the connecting plate II, so as not to affect the preliminary installation of the drill bit as described above.

[0021] In a specific embodiment, the telescopic and rotating part includes a telescopic member, a motor, and a U-shaped plate. The fixed end and the movable end of the telescopic member are respectively connected to the inner part of the U-shaped plate and the motor. The telescopic member is one of an electric push rod, a cylinder, a hydraulic cylinder, and an oil cylinder. The U-shaped plate is also fixed to the two connecting plates II. One end of the drill bit is connected to the output end of the motor.

[0022] In the above implementation process, the telescopic member is used to drive the drill bit to extend and move, that is, it is convenient to control the drilling depth of the drill bit, and the motor is used to drive the drill bit to rotate and drill. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0031] Please refer to Figure 1, this application provides a drill bit structure, including a drill bit connection component 10 and a drill bit component 20.

[0032] Among them, the drill bit connection component 10 can adjustably dock and fix the drill bit component 20 on an external loading device. During the operation of adjustment and fixation, external tools are not required, which increases the convenience of the inclination adjustment of the drill bit 220.

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 , the drill bit connection component 10 includes a rectangular plate 110, two fixed plates 120, and two connecting plates I 130. The two fixed plates 120 and the two connecting plates I 130 are respectively arranged on both sides of the rectangular plate 110. A connecting cylinder 140 is commonly connected between the two connecting plates I 130. A docking part 150 is arranged in the connecting cylinder 140, and both ends of the docking part 150 extend out of the outer sides of both ends of the connecting cylinder 140 movably. A docking hole I 160 distributed around the axis of the connecting cylinder 140 is also evenly spaced and penetrated through the two connecting plates I 130.

[0034] In this embodiment, the two fixed plates 120 are parallel to each other and are respectively connected to both sides of one surface of the rectangular plate 110 by welding. The fixed plates 120 and the rectangular plate 110 are perpendicular to each other. The two fixed plates 120 have the same specifications and are both provided with mounting holes in pairs. A circular ring sleeve is also welded and fixed in each mounting hole. Among them, the cooperation of the mounting holes and the circular ring sleeves on the fixed plates 120 facilitates the firm installation of the fixed plates 120 and the external loading device.

[0035] In this embodiment, two reinforcing plates 170 are also welded and fixed in pairs on the opposite surfaces of the two fixed plates 120. One side of the two reinforcing plates 170 is also welded and fixed to the rectangular plate 110. Among them, the setting of the reinforcing plates 170 can increase the connection stability between the two fixed plates 120 and the rectangular plate 110, and indirectly improve the stability of the overall structure of this device.

[0036] In this embodiment, the two connecting plates I 130 are parallel to each other and are also respectively connected to the other surface of the rectangular plate 110 by welding, and are located near the other two sides of the rectangular plate 110. The connecting plates I 130 and the rectangular plate 110 are perpendicular to each other. Among them, the welding fixing method can increase the connection stability between the connecting plates I 130 and the rectangular plate 110, and also indirectly improve the stability of the overall structure of this device.

[0037] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5, the drill bit assembly 20 includes a telescopic and rotating part 210, a drill bit 220, and two connecting plates II 230. The drill bit 220 and the two connecting plates II 230 are respectively arranged at both ends of the telescopic and rotating part 210. The opposite surfaces of the two connecting plates II 230 are respectively attached to the separated surfaces of the two connecting plates I 130. Through holes 240 corresponding to the connecting cylinder 140 are respectively formed through the two connecting plates II 230. The docking member 150 can be movably inserted into the through holes and continue to extend outward. A plurality of plug-in members 250 corresponding to and mating with each docking hole I 160 are also installed on the separated sides of the two connecting plates II 230. Moreover, the two connecting plates II 230 and the two connecting plates I 130 can be fixed in an adjustable manner by means of the plug-in members 250.

[0038] In this embodiment, the docking member 150 includes an intermediate rod 151, two plug-in sleeves 152, and a connecting ring 153. The outer ring of the connecting ring 153 is fixedly welded to the middle part of the inner wall of the connecting cylinder 140, and they are coaxially arranged. The intermediate rod 151 is inserted and fixed into the inner ring of the connecting ring 153. Specifically, the outer ring of the intermediate rod 151 is connected and fixed to the connecting ring 153 by welding, with relatively high stability. Both ends of the intermediate rod 151 are respectively slidably sleeved with the two plug-in sleeves 152. Specifically, sliders are arranged on the inner wall of the plug-in sleeve 152, and slide rails corresponding to the sliders are arranged on the outer wall of the intermediate rod 151. The cooperation of the sliders and the slide rails can reduce the probability of their separation under the thrust of the spring I 154. Spring I 154 is fixedly welded to the inner ends of the two plug-in sleeves 152 and the outer ends of the intermediate rod 151. The plug-in sleeve 152 is movably inserted into the through hole 240 by the driving force of the spring I 154, and the outer diameter of the plug-in sleeve 152 is the same as the inner diameter of the through hole 240. Among them, when the plug-in sleeves 152 at both ends are pressed towards the inner cavity of the connecting cylinder 140, and then the opposite surfaces of the two connecting plates II 230 are slowly pushed towards the separated surfaces of the two connecting plates I 130, when the connecting plate II 230 presses on the plug-in sleeve 152, it is no longer necessary to continue pressing the plug-in sleeve 152. When the plug-in sleeve 152 aligns with the through hole 240 formed in the connecting plate II 230, the spring I 154 will restore its elastic force to drive the plug-in sleeve 152 to insert into the through hole 240, thereby indirectly completing the preliminary installation of the drill bit 220.

[0039] In this embodiment, the connecting plate II 230 is also provided with through connecting holes II 260 at equal intervals, and the apertures of the connecting holes II 260 are the same as those of the docking holes I 160. The number of the plug connectors 250 is the same as that of the connecting holes II 260 and they are arranged in one-to-one correspondence. All the plug connectors 250 include positioning rods 251, pull rods 252 and two springs II 253. The positioning rods 251 are inserted and fixed with the corresponding connecting holes II 260 and docking holes I 160. One end of the positioning rod 251 is fixedly welded to the central part of the pull rod 252. One ends of the two springs II 253 are connected to the pull rod 252 and are symmetrically arranged with respect to the positioning rod 251. The other ends of the two springs II 253 are fixedly connected to the connecting plate II 230. Among them, the two ends of the spring II 253 are fixedly welded to the structures they are connected to respectively. When using the plug connector 250, according to the direction that the drill bit 220 needs to be adjusted, rotate the drill bit 220 to align the connecting holes II 260 on the connecting plate II 230 with the corresponding docking holes I 160 on the connecting plate I 130. After alignment, pull the two ends of the pull rod 252 outwards so that the spring II 253 is in an extended state, and then insert the positioning rod 251 into the corresponding connecting holes II 260 and docking holes I 160, thereby indirectly completing the adjustment and fixation of the drill bit 220. When the positioning rod 251 is not needed, the positioning rod 251 can be pulled out to the outside of the corresponding hole, and its end is abutted against the outside of the connecting plate II 230, so as not to affect the preliminary installation of the drill bit 220 mentioned above.

[0040] In this embodiment, the telescopic and rotating part 210 includes a telescopic member 211, a motor 212 and a U-shaped plate 213. The fixed end and the movable end of the telescopic member 211 are respectively connected to the inner part of the U-shaped plate 213 and the motor 212. The telescopic member 211 is one of an electric push rod, a cylinder, a hydraulic cylinder and an oil cylinder. The U-shaped plate 213 is also fixed to the two connecting plates II 230. One end of the drill bit 220 is connected to the output end of the motor 212 through a coupling. Among them, the telescopic member 211 can be rotated and fixed to the U-shaped plate 213 and the motor 212 by screws. The telescopic member 211 is used to drive the drill bit 220 to extend and move, that is, it is convenient to control the drilling depth of the drill bit 220, and the motor 212 is used to drive the drill bit 220 to rotate and drill.

[0041] The working principle of this drill bit structure:

[0042] After the fixing plate 120 is pre-fixed to an external carrying device, the plug sleeves 152 at both ends are pressed towards the inner cavity of the connecting cylinder 140, and then the opposite surfaces of the two connecting plates II 230 are slowly pushed towards the separated surfaces of the two connecting plates I 130. When the plug sleeve 152 is aligned with the through holes 240 formed in the connecting plate II 230, the spring I 154 restores its elasticity to drive the plug sleeve 152 to insert into the through holes 240, thereby indirectly completing the preliminary installation of the drill bit 220. Then, according to the direction in which the drill bit 220 needs to be adjusted, the drill bit 220 is rotated so that the docking holes II 260 on the connecting plate II 230 are aligned with the corresponding docking holes I 160 on the connecting plate I 130. After alignment, the two ends of the pull rod 252 are pulled outwards so that the spring II 253 is in an extended state, and then the positioning rod 251 is inserted into the corresponding docking holes II 260 and docking holes I 160, thereby indirectly completing the adjustment and fixing of the drill bit 220.

[0043] It should be noted that the specific model specifications of the spring I 154, the telescopic member 211, the motor 212, and the spring II 253 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0044] The power supply and principle of the telescopic member 211 and the motor 212 are clear to those skilled in the art and will not be described in detail here.

[0045] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
