Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a precision drilling device for I-beam profiles used in sunroom structures. Background Technology

[0002] A sunroom, also known as a glass room, is a fully transparent, non-traditional building constructed with glass and a metal frame. Its purpose is to allow residents to enjoy sunlight and connect with nature. It is widely used in residential, commercial, and public buildings as a garden greenhouse, a tea room, or a space extension. The core load-bearing and frame structure of a sunroom is mainly composed of profiles. Among them, I-beams, due to their "I"-shaped cross-section, possess excellent bending strength and structural stability, and are often used as key load-bearing components such as the main beams and joists of a sunroom. These I-beams require precise symmetrical drilling to achieve a secure connection with other profiles in the structure.

[0003] Existing drilling equipment mostly uses automatic bench drills. During drilling, the automatic feed mechanism of the equipment drives the I-beam to the bottom of the drill bit under the action of friction to perform drilling operations. However, since the automatic feed mechanism and the I-beam are driven by clamping friction, slippage is likely to occur, the effective conveying distance becomes shorter, and it is impossible to detect during drilling, thus affecting the drilling accuracy.

[0017] See Figure 1-7 A precision drilling device for I-beam profiles in a sunroom structure includes a base 1, a fixture mechanism and a drilling mechanism.

The limiting assembly includes a slider 5, a sliding rod 6, a pressure block 7, a ball 8, a retaining ring 9, and a pressure sensing device 10. The slider 5 is horizontally and longitudinally slidably sleeved on the sliding assembly. The sliding rod 6 is vertically slidably sleeved inside the slider 5.

A spring 11 is vertically sleeved on the sliding rod 6. The upper and lower ends of the spring 11 are fixedly connected to the input end of the pressure sensing device 10 and the upper side of the retaining ring 9, respectively. The ball 8 is rotatably embedded in the bottom end of the pressure block 7. The sliding assembly is used to adjust the distance between the two sets of limiting assemblies, and a pushing mechanism is provided on the upper side of the base 1 to drive the profile to move.

[0018] The entire device is powered by an external power source and controlled by a control system.

[0019] The lifting assembly includes a support plate 3 and two first telescopic cylinders 4. The support plate 3 is horizontally arranged on the bottom side of the upper end of the truss 2. The two first telescopic cylinders 4 are vertically arranged, and their two ends are fixedly connected to the sides of the truss 2 and the support plate 3 that are close to each other. The sliding assembly is arranged on the left side of the support plate 3.

[0020] The sliding assembly includes a frame 12, a slide 13, two sets of servo sliding devices 14, and a second telescopic cylinder 15. The frame 12 is horizontally fixedly installed on the left side of the support plate 3. The slide 13 is horizontally longitudinally arranged, and its two ends are slidably sleeved on the frame 12. The two sets of servo sliding devices 14 are respectively installed at both ends of the slide 13 to drive the slide 13 to move on the frame 12. The second telescopic cylinder 15 is horizontally longitudinally arranged, and its middle part is fixedly connected to the slide 13 through a connecting frame 39. The ends of the two sliders 5 that are close to each other are fixedly connected to the two ends of the second telescopic cylinder 15.

[0021] The servo sliding device 14 adjusts the horizontal lateral distance between the limiting component and the drilling component, and the second telescopic cylinder 15 adjusts the horizontal longitudinal distance between the two sets of limiting components to meet the operational requirements of holes with different spacing.

[0022] The drilling assembly includes a drive component and two sets of drill bit components. The drill bit components include a drill rod 16, a caliper device 17, a connecting rod 18, and a slide 19. The slide 19 is horizontally and longitudinally slidably embedded in the bottom side of the support plate 3. The caliper device 17 is vertically rotatably sleeved in the slide 19. The two slides 19 are connected by a linkage component. The connecting rod 18 is vertically arranged, and its top end is clamped in the caliper device 17. The drill rod 16 is vertically arranged, and its top end is threadedly sleeved with the bottom end of the connecting rod 18. The top ends of the two caliper devices 17 are connected by a drive component. The drill rod 16 and the connecting rod 18 have the same diameter. The connecting rod 18 is provided with a deburring mechanism.

[0023] The direction of rotational feed of drill pipe 16 will cause drill pipe 16 to be screwed tightly to the bottom end of connecting rod 18.

[0024] The linkage assembly includes a motor 20 and a screw 21. The screw 21 is horizontally and longitudinally rotatably sleeved inside the support plate 3. The motor 20 is horizontally and fixedly installed on the upper side of the support plate 3, and its output end is fixedly connected to the end of the screw 21. Two slides 19 are threadedly sleeved on the screw 21. The motor 20 drives the screw 21 to rotate, so that the screw 21 drives the two slides 19 to move closer or further away from each other at the same time, thereby satisfying the spacing of the paired holes in the same assembly.

[0025] The driving components include a motor 22, a first gear set 23, a main shaft 24, two drive shafts 25, and two sets of second gear sets 26. The motor 22 is vertically fixed at the top of the support plate 3. The main shaft 24 is horizontally and longitudinally rotatably sleeved in the middle of the support plate 3. The two drive shafts 25 are horizontally and longitudinally rotatably sleeved in two slides 19, with their ends close to each other slidingly sleeved at both ends of the main shaft 24. The output end of the motor 22 is meshed with the middle of the main shaft 24 through the first gear set 23. The ends of the drive shafts 25 away from the main shaft 24 are meshed with the top of the caliper device 17 through the second gear set 26. When the motor 22 starts, it drives the main shaft 24 to rotate through the first gear set 23. The main shaft 24 drives the two drive shafts 25 to rotate. The drive shafts 25 drive the caliper device 17 to rotate through the second gear set 26, thereby driving the drill rod 16 and the connecting rod 18 to rotate, realizing drilling and deburring operations.

[0026] The fixture mechanism includes a clamp 27 and two sets of tensioning components. The clamp 27 is vertically fixed on the base 1. The two sets of tensioning components are symmetrically arranged inside the clamp 27. The tensioning components include a pusher 28, a third telescopic cylinder 29, two clamping plates 30, a fourth telescopic cylinder 31, and two sets of opening and closing parts. The opening and closing parts include connecting blocks 32 and two support rods 33. The pusher 28 is horizontally slidably sleeved inside the clamp 27. The third telescopic cylinder 29 is horizontally arranged, and its two ends are fixedly connected to the outer side of the clamp 27 and the middle of the pusher 28, respectively. The fourth telescopic cylinder 31 is horizontally fixedly sleeved at the end of the pusher 28 located inside the clamp 27. The two connecting blocks 32 are vertically fixedly installed at both ends of the fourth telescopic cylinder 31. The two clamping plates 30 are horizontally arranged symmetrically from top to bottom. The clamping plates 30 have a right-angle structure. Multiple rollers 34 are rotatably installed on the two inner right-angle sidewalls. The two support rods 33 are symmetrically arranged from top to bottom. The two ends of each support rod 33 are hinged to the clamping plate 30 and the connecting block 32, respectively, through pins.

[0027] The third telescopic cylinder 29 extends and retracts, adjusting the position of the pusher 28, thereby adjusting the position of the fourth telescopic cylinder 31, and further adjusting the distance between the two pairs of horizontal longitudinal clamping plates 30. The extension or retraction of the fourth telescopic cylinder 31 drives the two connecting blocks 32 to move closer or further away, causing the two pairs of support rods 33 to deflect, thereby adjusting the distance between the two upper and lower opposing clamping plates 30, so that the roller 34 clamps the profile, achieving the clamping of the profile.

[0028] The pushing mechanism includes a power roller device 35 and multiple fifth telescopic cylinders 36. The multiple fifth telescopic cylinders 36 are all vertically fixedly installed on the upper side of the base 1 and are symmetrically arranged. The power roller device 35 is horizontally arranged and passes through the card holder 27. The bottom side of the power roller device 35 is fixedly connected to the top of the multiple fifth telescopic cylinders 36.

[0029] The multiple rollers in the power roller device 35 are made of a friction-generating material to provide friction for the conveying of the profile, while preventing the profile from sliding during self-locking.

[0030] The deburring mechanism includes two scraper rods 37 and multiple compression springs 38. The two scraper rods 37 are symmetrically and vertically arranged and horizontally slidably embedded in the connecting rod 18. The upper and lower sides of the scraper rods 37 are chamfered. The multiple compression springs 38 are horizontally arranged and divided into two groups. The two ends of each compression spring 38 are fixedly connected to the connecting rod 18 and the inner wall of the scraper rod 37, respectively.

[0031] When using this equipment to drill holes in I-beam profiles, first adjust the two sets of drill bit components and the two sets of limiting components to the required hole spacing. Initially, spring 11 is at its original length and ball bearing 8 is at the bottom. Servo sliding device 14 is activated, causing slide 13 to move the two sets of limiting components. Finally, the distance between the outer circle of pressure block 7 and the center of drill rod 16 is equal to the distance between the first set of holes and the end of the profile. The profile is placed on the fixture mechanism, and four clamping plates 30 clamp the horizontal end of the I-beam profile, so that the profile is in the center position. Then, the fifth telescopic cylinder 36 extends, so that multiple power rollers on the upper side of the power roller device 35 contact the bottom surface of the profile. After activation, the profile is driven to move in the direction from drill rod 16 to ball bearing 8.

[0032] After the end of the profile contacts the outside of the pressure block 7, the power roller device 35 stops operating and self-locks. Then, the first telescopic cylinder 4 extends, the motor 22 starts, and drives the two clamp devices 17 to rotate synchronously and move downwards through the drive component to drill the profile. After the hole is penetrated, the connecting rod 18 drives the scraper 37 to move downwards and first contact the upper edge of the hole. The chamfer at the bottom of the scraper 37 deburrs the upper edge of the hole. During deburring, the first telescopic cylinder 4 remains stationary. After the upper edge is deburred, the first telescopic cylinder 4 extends, causing the connecting rod 18 to continue to move downwards. The scraper 37 is pressed into the connecting rod 18, and the compression spring 38 is compressed. After penetrating the through hole, the chamfer on the upper side of the scraper 37 contacts the bottom edge of the hole and performs deburring again. This achieves deburring after drilling, avoids subsequent secondary processing, ensures the quality of the hole, and improves the overall processing efficiency.

[0033] After the deburring operation is completed, the first telescopic cylinder 4 shortens, causing the drill rod 16 and connecting rod 18 to move upward and disengage from the completed hole. Finally, the bottom end of the drill rod 16 disengages from the upper side of the profile, the bottom end of the ball bearing 8 is lower than the upper surface of the profile, and the bottom surface of the pressure block 7 is higher than the upper surface of the profile. The servo sliding device 14 is restarted, driving the two sets of limit components to move, so that the horizontal distance between the center of the ball bearing 8 and the center of the drill rod 16 is equal to the preset distance between adjacent holes. Then the servo sliding device 14 stops and self-locks, and then the power roller device 35 is unlocked and started to transport the profile, and the ball bearing 8 rolls on the surface of the profile.

[0034] When the ball bearing 8 coincides with the hole, the compression of the spring 11 will decrease. At this time, the pressure sensor 10 will sense the pressure value of the spring 11 and feed it back to the control system of the equipment to determine whether the ball bearing 8 is located in the hole that has been completed. At this time, the drill rod 16 is located directly above the area to be drilled next. Since the horizontal distance between the ball bearing 8 and the drill rod 16 is fixed, the accuracy of drilling is guaranteed.

[0035] Since the burrs have been removed beforehand, the ball bearing 8 will not be disturbed when it comes into contact with the hole.

[0036] When slippage occurs between the power roller device 35 and the profile, the profile will move too short a distance, resulting in the hole spacing being less than the preset spacing. At this time, the ball bearing 8 will not overlap with the previous set of holes. Therefore, the pressure sensor device 10 can determine that the conveying distance is not up to standard and adjust the conveying distance in time to ensure the accuracy of the conveying distance and the drilling precision.

[0037] The drill rod 16 is screwed to the connecting rod 18, which makes it easy to change the combination according to the chamfering requirements of the scraper 37. The pressure block 7 is screwed to the bottom of the slide rod 6, which makes it easy to change the ball bearings 8 of different specifications according to the hole diameter.

[0038] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
