Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] As attached Figure 1 -Appendix Figure 5 As shown, a profile drilling device suitable for aluminum alloy door and window processing includes a machine base 1, a limiting beam 2 on the machine base 1, a profile placement area 3 formed at the front end of the limiting beam 2, a column 4 at the rear end of the machine base 1, a liftable mounting plate 5 at the front end of the column 4, a plurality of adjustable plates 6 with adjustable lateral distance at the front end of the mounting plate 5, and a drilling assembly installed at the lower end of the adjustable plates 6.

[0028] In one embodiment, in order to enable the drilling assembly to be raised and lowered to drill holes in aluminum alloy door and window profiles, the front end of the column 4 is provided with a first longitudinal guide rail 7, and the back of the mounting plate 5 is slidably engaged with the first longitudinal guide rail 7 via a first longitudinal slider. The upper top plate 8 and the lower bottom plate 9 are respectively provided above and below the front end of the column 4. A lifting screw 10 is rotatably provided between the upper top plate 8 and the lower bottom plate 9. The first longitudinal slider is threadedly connected to the lifting screw 10, and the lifting screw 10 is driven by a lifting motor 11 provided on the upper top plate 8. Starting the lifting motor 11 drives the lifting screw 10 to rotate. The forward and reverse rotation of the lifting screw 10 can drive the mounting plate 5 to rise and fall, thereby driving the drilling assembly to rise and fall. The sliding engagement of the first longitudinal guide rail 7 with the first longitudinal guide rail 8 is conducive to stabilizing the lifting direction of the mounting plate 5.

[0029] In one embodiment, to facilitate adjustment of the lateral drilling position of the drilling assembly according to drilling needs, the front end of the mounting plate 5 is provided with a lateral guide rail 12, the back of the adjusting plate 6 is provided with a lateral slider 13 that slides with the lateral guide rail 12, a driving mechanism is provided on one side of the front end of the mounting plate 5, a driving plate 14 is connected to the driving mechanism, and the driving mechanism can drive the driving plate 14 to move up and down, the front end of the driving plate 14 is provided with oppositely arranged oblique slots 15, and the front end of the adjusting plate 6 is provided with an adjusting wheel 16 located in the oblique slots 15. When the driving mechanism is activated, when the driving mechanism drives the driving plate 14 to move downward, the driving plate 14 drives the adjusting wheel 16 to move vertically downward. Since the adjusting wheel 16 is slidably disposed in the oblique slots 15, when the adjusting wheel 16 moves downward, it can drive the adjusting plates 6 on both sides to move outward respectively. When the driving mechanism drives the driving plate 14 to move upward, when the adjusting wheel 16 moves upward, it can drive the adjusting plates 6 on both sides to move inward respectively, thereby enabling adjustment of the lateral drilling position of the drilling assembly according to drilling needs.

[0030] In one embodiment, to enable the lifting and lowering of the drive plate 14, the drive mechanism includes an upper mounting base 17 and a lower mounting base 18 disposed at the front end of the mounting plate 5. An adjusting screw 19 is rotatably disposed between the upper mounting base 17 and the lower mounting base 18. The adjusting screw 19 is driven by an adjusting motor 20 disposed on the upper mounting base 17. An adjusting sleeve 21 fixed to the drive plate 14 is threadedly connected to the adjusting screw 19. A second longitudinal guide rail 22 is also provided on one side of the front end of the mounting plate 5. The back of the drive plate 14 is slidably connected to the second longitudinal guide rail 22 through a second longitudinal slider. When the adjusting motor 20 is started, it drives the adjusting screw 19 to rotate. The adjusting screw 19 can drive the adjusting sleeve 21 to lift and lower. The cooperation between the second longitudinal guide rail 22 and the second longitudinal slider facilitates the stabilization of the lifting and lowering direction of the drive plate 14.

[0031] In one embodiment, to enable multiple drilling operations on door and window profiles at once, the mounting plate 5 has side plates 23 on both sides of its front bottom. A drive shaft 24 is rotatably connected between the two side plates 23, and the drive shaft 24 is driven by a drive motor 25 located on one side of the side plate 23. The drilling assembly includes a rear row of drill bits 26, a front row of drill bits 27, and an L-shaped connecting plate 28 mounted on the front end of the adjusting plate 6. The L-shaped connecting plate 28 includes a vertical part and a horizontal part. A mounting sleeve 29 is transversely passed through the vertical part of the L-shaped connecting plate 28, and the mounting sleeve 29 is rotatably connected to the L-shaped connecting plate 28. The L-shaped connecting plate 28 is fitted onto the drive shaft 24 through the mounting sleeve 29 and can slide left and right on the drive shaft 24. The inner hole of the mounting sleeve 29 has a keyway 30, and the drive shaft 24 has a key bar 31 that mates with the keyway 30. One end of the mounting sleeve 29 has a drive bevel gear 32. A rear row of drill bit mounting shaft 33 is rotatably mounted on the horizontal part of the L-shaped connecting plate 28. The drill bit 26 is installed at the lower end of the rear drill bit mounting shaft 33. The upper end of the rear drill bit mounting shaft 33 is provided with a driven bevel gear 34 that meshes with the driving bevel gear 32. The keyway 30 and key bar 31 are designed to ensure that the distance between the multiple rear drill bits 26 can be adjusted as needed and that they can rotate synchronously under the action of the drive shaft 24. When the distance between the adjusting plates 6 is adjusted, the L-shaped connecting plate 28 can slide left and right on the key bar 31 of the drive shaft 24 through the keyway 30 in the inner hole of the mounting sleeve 29. When drilling is required, the drive motor 25 is started to drive the drive shaft 24 to rotate. Under the limiting action of the keyway 30 and key bar 31, the mounting sleeve 29 rotates with the drive shaft 24. The mounting sleeve 29 drives the driving bevel gear 32 at its end to rotate. The driving bevel gear 32, in conjunction with the driven bevel gear 34, can drive the rotation of the rear drill bit mounting shaft 33 and the rear drill bits 26, thereby enabling the multiple rear drill bits 26 to drill synchronously.

[0032] In one embodiment, in order to adjust the front-to-back distance between the rear row of drill bits 26 and the front row of drill bits 27 as needed, and to drive the rotation of the front row of drill bits 27 while the rear row of drill bits 26 rotates, an adjusting seat 35 is provided at the front end of the horizontal part of the L-shaped connecting plate 28. The adjusting seat 35 has a through hole in the middle and a movable seat 36 is slidably provided in the through hole. An adjusting screw 37 is threadedly connected to the front end of the adjusting seat 35, and the pushing end of the adjusting screw 37 is rotatably connected to the movable seat 36. A front row of drill bit mounting shaft 38 is rotatably provided on the movable seat 36, and the front row of drill bits 27 is mounted on the lower end of the front row of drill bit mounting shaft 38. The lower parts of the rear row of drill bit mounting shaft 33 and the front row of drill bit mounting shaft 38 are respectively provided with The driving wheel 39 and the driven wheel 40 are connected by a detachable belt. When it is necessary to adjust the front-to-back distance between the rear drill bit 26 and the front drill bit 27 as needed, the belt is first removed, and the adjusting screw 37 is rotated. The adjusting screw 37 drives the moving seat 36 to move back and forth. After the distance between the rear drill bit 26 and the front drill bit 27 is adjusted, a suitable belt is selected and fitted between the driving wheel 39 and the driven wheel 40 so that the rotation of the rear drill bit 26 can drive the rotation of the front drill bit 27. In a specific embodiment, the adjusting seat 35 is also provided with scale lines to accurately control the front-to-back distance between the rear drill bit 26 and the front drill bit 27.

[0033] In one embodiment, to prevent the profile from shaking during processing, a front clamping cylinder 41 is provided at the front end of the profile placement area 3, and a front clamping plate 42 is provided at the end of the piston rod of the front clamping cylinder 41. A pressing cylinder 43 is provided at the rear end of the machine base 1, and a pressure plate 44 is provided at the top of the piston rod of the pressing cylinder 43. When the back of the profile to be drilled is attached to the front end face of the limiting beam 2, the front clamping cylinder 41 is activated to push the front clamping plate 42 to press the front end of the profile to prevent the profile from moving back and forth. The pressing cylinder 43 is also activated, and the piston rod of the pressing cylinder 43 shortens, causing the pressure plate 44 to press down on the profile, thereby preventing the profile from shaking up and down.

[0034] In one embodiment, to accurately drill holes at corresponding positions on the profile, one end of the limiting beam 2 extends to the outside of the discharge end of the machine 1. A plurality of limiting seats 45 are provided at the outer end of the limiting beam 2. A limiting baffle 46 is rotatably provided at one end of each limiting seat 45. The limiting baffle 46 has a groove 47 that mates with one side of the limiting beam 2. A positioning screw 48 is threaded onto the limiting seat 45. A T-slot 49 is provided on the limiting beam 2. The lower end of the positioning screw 48 is provided to slide within the T-slot 49. The positioning block 50 allows one end of the profile to abut against the first limiting baffle 46. After drilling is completed, the first limiting baffle 46 can be rotated upwards. At this time, the profile is pulled forward so that the end of the profile abuts against the second limiting baffle 46, thereby accurately controlling the lateral position of the profile. In the specific implementation process, the limiting seat 45 can slide on the limiting beam 2 and be locked and fixed by the positioning screw 48. The limiting beam 2 can be engraved with corresponding scales to facilitate the positioning of the limiting seat 45 against the limiting baffle 46.

[0035] In one embodiment, the loading end of the machine base 1 is provided with a loading frame 51, and a plurality of guide rollers 52 are rotatably mounted on the loading frame 51, which facilitates the loading and movement of the profile.

[0036] Working Principle: The aluminum alloy door and window profile is placed in the profile placement area 3 at the front end of the limiting beam 2 on the machine base 1. The front clamping cylinder 41 is activated, pushing the front clamping plate 42 to press the front end of the profile, preventing it from moving back and forth. The pressing cylinder 43 is activated, and the piston rod of the pressing cylinder 43 shortens, driving the pressure plate 44 to press down on the profile, preventing it from swaying up and down. According to the drilling requirements, the drive mechanism is adjusted, causing the drive plate 14 to move up and down, driving the adjusting wheel 16 to move up or down. Since the adjusting wheel 16 is slidably set in the inclined slot 15, when the adjusting wheel 16 moves downwards, it can drive the adjusting plates 6 on both sides to move outwards respectively. When the drive mechanism drives the drive plate 14 to move upwards, the adjusting wheel 16 moves upwards, driving the adjusting plates 6 on both sides to move inwards respectively, thereby adjusting the lateral drilling position of the drilling assembly. The lifting motor 11 is activated, driving the rotation of the lifting screw 10. The forward and reverse rotation of the lifting screw 10 can drive the lifting of the mounting plate 5, thereby driving the lifting of the drilling assembly.

[0037] Positioning is achieved using the limit baffle 46, placing the profile in the desired drilling location. The drive motor 25 is started, and the drive shaft 24 rotates, driving the rear drill bit 26 and the front drill bit 27 synchronously via a belt connection, enabling multiple holes to be drilled in the door / window profile at once. If the distance between the rear drill bit 26 and the front drill bit 27 needs adjustment, the belt is removed, and the adjusting screw 37 moves the moving seat 36 back and forth. After adjustment, the belt is reinstalled so that the rotation of the rear drill bit 26 simultaneously drives the rotation of the front drill bit 27. After drilling the first section, the first limit baffle 46 is rotated, and the profile is pulled forward until its end abuts against the second limit baffle 46, thus precisely controlling the lateral position of the profile for accurate drilling of the second section. The distance between the rear drill bit 26 and the front drill bit 27 can be precisely adjusted using the scale lines as needed. During drilling, the profile moves on the feeding rack 51, and the guide roller 52 facilitates smooth feeding of the profile.
