Description

Technical Field

This profile not only provides a solid supporting structure for the luggage, but also gives it an aesthetically pleasing appearance. However, during the drilling process of aluminum frame profiles for luggage, the drilling accuracy and efficiency are often severely affected due to the specific characteristics of the profiles and the limitations of traditional drilling equipment.

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figures 1 to 10As shown: A drilling device for aluminum frame profiles for luggage boxes, including a frame 1 and a processing table 11 arranged on the frame 1 for placing the aluminum frame profiles, two sides of the processing table 11 are provided with downward pressure cylinders 12 capable of clamping the two ends of the aluminum frame profiles, the frame 1 is also provided with a linear slide 13 located above the processing table 11, the working end of the linear slide 13 is installed with a bracket 14, the bracket 14 is provided with a lifting drive mechanism 15, the working end of the lifting drive mechanism 15 is provided with a drilling machine 16, the drilling machine 16 is equipped with a drilling cutter head 161, the axis of the drilling cutter head 161 is perpendicular to the table surface of the processing table 11, and the bracket 14 is provided with a follow-up clamping mechanism 2, the follow-up clamping mechanism 2 includes two clamps 21 for clamping the outer side of the aluminum frame profile, one side of the clamp 21 is provided with a translation bevel block 22, and both sides of the drilling machine 16 are provided with downward pressing bevel blocks 23 corresponding to each translation bevel block 22, the bottom of the downward pressing bevel block 23 is formed with a first inclined surface, and the top of the translation bevel block 22 is formed with a second inclined surface that can slide with the first inclined surface. When the drilling machine 16 moves downward, the first inclined surface of the downward pressing bevel block 23 slides with the second inclined surface of the translation bevel block 22, so that the translation bevel blocks 22 on both sides simultaneously push the clamps 21 on both sides to move along the processing table 11 to clamp the outer side of the aluminum frame profile placed on the processing table 11.

[0035] The specific operation process is as follows: First, the aluminum frame profile to be drilled is placed on the processing table 11 manually or by a robot, and then the downward pressure cylinder 12 on the processing table 11 is pre-activated to firmly fix the two ends of the aluminum frame profile; After the aluminum frame profile is fixed, the linear slide 13 drives the drilling machine 16 to move accurately to the processing position and stop. At this time, the drilling head 161 of the drilling machine 16 has been accurately aligned with the processing area of ​​the aluminum frame profile; At the same time, the linear slide 13 also drives the follow-up clamping mechanism 2 to move to the processing position through the bracket 14 during the process of moving the drilling machine 16, ensuring that the follow-up clamping mechanism 2 and the drilling machine 16 are in place synchronously; When the drilling machine 16 and the follow-up clamping mechanism 2 both reach the position to be processed, the drilling machine 16 is started to operate, and the lifting drive mechanism 15 drives the drilling machine 16 to slowly move downward. When the predetermined height is reached, the downward pressing inclined block 23 of the follow-up clamping mechanism 2 contacts and slides with the translation inclined block 22. During this process, the translation inclined block 22 is pushed to translate toward the aluminum frame profile, and the clamp 21 on one side of the translation inclined block 22 clamps the surrounding area of ​​the aluminum frame profile to be drilled. It is particularly noted that there is enough space between the two clamps 21 to ensure the normal movement of the drilling tool head 161 during the drilling process. Finally, after the periphery of the drilling area of ​​the aluminum frame profile is tightly fixed by the clamp 21, the drilling machine 16 starts its rotating drilling cutter head 161 and begins to perform precise drilling operations on the aluminum frame profile.

[0036] By following the clamping mechanism 2, the movement of the drilling bit 161 can be dynamically followed during the drilling process to clamp the area of ​​the aluminum frame profile to be drilled. Compared with the traditional fixed clamping method, it can more effectively reduce the micro-vibration caused by drilling, thereby improving the drilling accuracy.

[0037] Reference Figures 1 to 4 As shown: the lifting drive mechanism 15 includes an L-shaped plate 151 and a vertical lifting plate 152; There is a pair of L-shaped plates 151, and the two L-shaped plates 151 are mirror-imaged and arranged on both sides of the drilling machine 16, and the L-shaped plates 151 are fixedly connected to the bracket 14; The number of vertical lifting plates 152 is the same as the number of L-shaped plates 151 and corresponds one to one. The two sides of the drilling machine 16 are respectively connected to the two vertical lifting plates 152. A dovetail slider 1521 is provided on the side of the vertical lifting plate 152 away from the drilling machine 16. A dovetail groove 1511 is provided on the L-shaped plate 151 for the vertical movement of the dovetail slider 1521. A rack 1522 is provided on the dovetail slider 1521 along its extension direction. A gear 1523 that can mesh with the rack 1522 is provided on the side of the L-shaped plate 151 away from the vertical lifting plate 152. An opening 1512 is provided on the L-shaped plate 151 to prevent the gear 1523 from rotating.

[0038] The lifting drive mechanism 15 also includes a servo motor 153 and a rotating shaft 154; the rotating shaft 154 is horizontally arranged on one side of the drilling machine 16, and the two ends of the rotating shaft 154 are respectively rotatably connected to the L-shaped plate 151. The outside of the rotating shaft 154 is coaxially provided with a first bevel tooth 155 corresponding to the gear 1523, and the gear 1523 is coaxially provided with a second bevel tooth 156 that can mesh with the first bevel tooth 155. The servo motor 153 is arranged on the frame 1, and the output shaft of the servo motor 153 is transmission-connected to one end of the rotating shaft 154.

[0039] When it is necessary to drive the drilling machine 16 to move downward, the servo motor 153 starts and drives the rotating shaft 154 to rotate. The rotating shaft 154 simultaneously drives two first bevel teeth 155 distributed thereon in opposite directions to rotate. When the two first bevel teeth 155 respectively drive their corresponding second bevel teeth 156, opposite rotation directions will be generated, that is, one of the second bevel teeth 156 rotates clockwise, and the other second bevel tooth 156 rotates counterclockwise. The rotation of the two second bevel teeth 156 is respectively transmitted to the corresponding gears 1523, and the gear 1523 is then connected to the rack 1522 by meshing with the gear 1523, driving the rack 1522 and the dovetail slider 1521 and the vertical lifting plate 152 connected thereto to move as a whole, thereby realizing the height adjustment of the drilling machine 16.

[0040] Reference Figures 1 to 4As shown: the lifting drive mechanism 15 also includes a stop plate 157, a limit rod 158 and a limit sleeve 159; The number of the stop plates 157 is the same as the number of the vertical lifting plates 152 and is arranged at the bottom of the vertical lifting plates 152 in a one-to-one correspondence. The stop plates 157 are arranged horizontally, and the tops of the stop plates 157 can be arranged to abut against the bottom of the L-shaped plate 151. The number of the limiting rods 158 is the same as the number of the stop plates 157 and they are arranged on the top of the stop plates 157 in a one-to-one correspondence. The limiting rods 158 are arranged vertically, and the tops of the limiting rods 158 pass through the L-shaped plate 151 and extend upward. The L-shaped plate 151 is provided with through holes for the limiting rods 158 to pass through. The number of the limiting sleeves 159 is the same as the number of the limiting rods 158 and they are arranged one-to-one at the extended ends of the limiting rods 158 . The bottom of the limiting sleeves 159 can be arranged to abut against the top surface of the lower section of the L-shaped plate 151 .

[0041] When the vertical lifting plate 152 moves up to the highest position, the stop plate 157 abuts against the bottom of the L-shaped plate 151, effectively preventing the vertical lifting plate 152 from moving upward excessively. Similarly, when the vertical lifting plate 152 moves down to the lowest position, the limit sleeve 159 provided at the extended end of the limit rod 158 will abut against the top surface of the lower section of the L-shaped plate 151.

[0042] Reference Figures 1 to 5 As shown: the follow-up clamping mechanism 2 also includes a spring compression rod 24 and a buffer structure 25; The number of the spring compression rods 24 is the same as the number of the stop plates 157 and corresponds one to one. The spring compression rods 24 are vertically arranged at the bottom of the stop plates 157, and one end of the spring compression rods 24 away from the stop plates 157 is connected to the top of the downward pressing inclined block 23; The number of the buffer structures 25 is the same as the number of the translational inclined blocks 22 and corresponds one to one. The buffer structures 25 are arranged between the translational inclined blocks 22 and the clamps 21 , and the buffer structures 25 are fixedly connected to the corresponding translational inclined blocks 22 and the clamps 21 , respectively.

[0043] The drilling machine 16 is provided with three preset working positions, which are described in detail as follows: The first stage: at this position, the drilling machine 16 is in a non-working state. At this time, the downward pressing bevel block 23 and the translation bevel block 22 are in a non-contact state, and the clamp 21 has not yet come into contact with the outer side of the aluminum frame profile to be processed.

[0044] The second stage: when the drilling machine 16 moves down to this position, its drilling head 161 has not yet contacted the aluminum frame profile. At this time, the downward pressing bevel block 23 has contacted the translation bevel block 22 and interacted with each other, driving the translation bevel block 22 and the clamp 21 to move toward the direction of the aluminum frame profile until the clamp 21 is in close contact with the outer wall of the aluminum frame profile.

[0045] The third stage: as the drilling machine 16 moves further downward, the spring compression rod 24 provided on the downward pressing bevel block 23 is compressed, making the fit between the downward pressing bevel block 23 and the translation bevel block 22 closer, and the buffer structure 25 between the clamp 21 and the translation bevel block 22 is also compressed, applying clamping force to the clamp 21.

[0046] The spring compression rod 24 mentioned in this embodiment is a prior art, and its specific structure and working principle will not be elaborated in detail here.

[0047] Reference Figures 4 to 6 As shown: the buffer structure 25 includes a connecting plate 251, a rectangular casing 252, a rectangular connecting block 253 and a first spring 254; The connecting plate 251 is vertically arranged on one side of the translation inclined block 22 close to the clamp 21; The rectangular casing 252 is vertically arranged on a side of the connecting plate 251 away from the translation inclined block 22, and a side of the rectangular casing 252 close to the clamp 21 is open; The rectangular connecting block 253 is vertically arranged on the side of the clamp 21 away from the processing table 11. The rectangular connecting block 253 can be slidably inserted into the rectangular shell 252 along the open end of the rectangular shell 252. First limit blocks 2531 are respectively provided on both sides of the rectangular connecting block 253. The rectangular shell 252 is provided with a first limit opening 2521 for the first limit block 2531 to translate. A blind hole is opened on one side of the rectangular connecting block 253 close to the rectangular shell 252. The first spring 254 is arranged in the blind hole. The two ends of the first spring 254 are respectively abutted against the deepest part of the blind hole and the inner wall of the rectangular shell 252.

[0048] When the clamp 21 is in contact with the outer side of the aluminum frame profile to be processed, the translational inclined block 22 drives the connecting plate 251 and the rectangular casing 252 to continuously move horizontally. During this process, the rectangular casing 252 applies pressure to the built-in first spring 254, causing it to be compressed, thereby giving the clamp 21 a buffering function. In order to ensure the stability of the movement of the clamp 21 and prevent the rectangular connecting block 253 from separating from the rectangular casing 252, the first stop block 2531 specially provided on the rectangular connecting block 253 will move along the first stop opening 2521 preset on the rectangular casing 252, which not only ensures the stability of the movement of the clamp 21, but also effectively avoids the separation between the rectangular connecting block 253 and the rectangular casing 252.

[0049] Reference Figure 1 and Figure 7 As shown: the follow-up clamping mechanism 2 also includes a moving plate 26, a light rod 27 and a second spring 28; The number of the movable plates 26 is the same as the number of the translation inclined blocks 22 and corresponds one to one. The movable plates 26 are horizontally arranged at the bottom of the translation inclined blocks 22. The polished rod 27 is horizontally arranged below the processing table 11, and the two ends of the polished rod 27 are respectively fixedly connected to the bracket 14. The bottom of the movable plate 26 is provided with a pressing sleeve 261 that can be slidably sleeved on the outside of the polished rod 27, and the two sides of the pressing sleeve 261 are respectively provided with second limit blocks 2611, and the bracket 14 is provided with a second limit opening 141 for the second limit block 2611 to move horizontally; The second spring 28 is sleeved on the outside of the polished rod 27 , and the second spring 28 is located between the two pressing sleeve plates 261 .

[0050] When the two clamps 21 clamp the outer side of the aluminum frame profile to be processed placed on the processing table 11, the second spring 28 is compressed by the two pressure sleeves 261 to store energy. When the clamp 21 releases the aluminum frame profile, the second spring 28 releases its stored energy to drive the clamp 21 to reset to its initial state. During the reset process, the two ends of the second spring 28 respectively push the two pressure sleeves 261 away from each other, thereby driving the movable plate 26, the translation bevel block 22 and the clamp 21 to move as a whole.

[0051] During the movement of the pressing sleeve 261, the second limit blocks 2611 arranged on both sides thereof move horizontally along the corresponding second limit openings 141 on the bracket 14, ensuring that the pressing sleeve 261 only moves under the constraint of the second limit openings 141, thereby limiting the preset position of the clamp 21 when it is reset, and ensuring the accuracy and stability of the processing.

[0052] Reference Figure 5 As shown: an inclined groove 221 is provided on the upper surface of the translation inclined block 22, a second inclined surface is formed by the inclined groove 221, a first chamfer 222 is provided at the edge of the groove 221, and a second chamfer 231 is provided at the bottom edge of the downward pressing inclined block 23.

[0053] During the downward movement of the drilling machine 16, the downward pressing bevel block 23 is inserted into the interior of the groove 221, and the first inclined surface on the downward pressing bevel block 23 slides in contact with the second inclined surface on the translation bevel block 22. Through the cooperation between the groove 221 and the downward pressing bevel block 23, the cooperation between the downward pressing bevel block 23 and the translation bevel block 22 is more stable.

[0054] Reference Fig.10 As shown: a cover plate 211 is respectively provided on one side adjacent to the two clamps 21. When the two clamps 21 are close to each other, the two cover plates 211 are combined to form a shielding space that can shield the front end of the drilling bit 161. The two cover plates 211 are provided with an avoidance opening 2111 for preventing the drilling bit 161 from rotating.

[0055] When the drilling head 161 is drilling holes in the aluminum frame profile, a large amount of debris will be generated. In order to ensure the smooth progress of the drilling process and effectively prevent the debris from splashing, when the aluminum frame profile is clamped and fixed by two clamps 21, the cover plates 211 on the two clamps 21 will be merged to form a shielding space. The debris generated by the drilling head 161 during the drilling process will be effectively shielded by the two merged cover plates 211, thereby avoiding the splashing of debris; when the drilling operation is completed, the two cover plates 211 will be unfolded, and the debris will remain at the processing position of the aluminum frame profile, which is convenient for subsequent centralized cleaning work.

[0056] Reference Figure 8 As shown: a rubber layer 212 capable of abutting against the outer side of the aluminum frame profile is provided on one side of the clamp 21 close to the processing table 11 .

[0057] When the two clamps 21 are close to the aluminum frame profile to be processed, the rubber layer 212 arranged on the inner side of the clamp 21 will be in close contact with the outer side of the aluminum frame profile. The softness of the rubber layer 212 can avoid scratching the outer wall of the aluminum frame profile during the clamping process, thereby ensuring the quality of the processed part.

[0058] Reference Fig.10 As shown: the outer sleeve of the drilling tool head 161 is provided with a chamfering tool 1611.

[0059] A chamfering tool 1611 is added to the outside of the drilling head 161. When the drilling head 161 moves down to the lowest working position, the chamfering tool 1611 will accurately chamfer the position of the hole opening of the drilled hole. The hole opening of the aluminum frame profile can directly obtain a good surface quality after drilling, and no subsequent polishing process is required. Through the synergistic effect of the chamfering tool 1611 and the drilling head 161, not only the drilling operation is realized, but also the chamfering and polishing of the hole opening are completed simultaneously, thereby improving the accuracy and overall quality of the processed hole.

[0060] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
