Description

Technical Field

[0001] This utility model relates to the field of bag handle punching technology, specifically an automatic bag handle punching device. Background Technology

[0002] A luggage handle is a metal tube that connects the luggage body to the bottom casters, usually located on the back or side of the luggage. The handle has multiple telescopic sections, allowing users to adjust the length as needed for better support and ease of movement during transport. During manufacturing, holes are typically punched to facilitate connection to the luggage body and bottom casters.

[0003] For example, a bag handle punching mechanism with announcement number "CN212857343U" uses a punching base and a handle that are interlocked. Multiple punching holes and a punching head are located above the protrusion, resulting in high punching efficiency. A clamping mechanism fixes the punching base to a fixed base, which can be disassembled and replaced to meet the punching needs of handles of different specifications. A buffer mechanism provides good protection for the punching head, preventing damage to the handle or punching base due to excessive punching force. However, this bag handle punching mechanism cannot punch handles with special shapes, increasing its limitations. Furthermore, when punching needs to be done at other horizontal positions on the handle, the operator needs to change the handle's position and re-fix it, which takes a considerable amount of time, thus reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when it is necessary to drill holes in other special-shaped luggage handles, it is impossible to drill holes in special-shaped handles, which increases the limitation of work. At the same time, when the luggage handle drilling mechanism needs to drill holes in other positions at the horizontal level of the handle, the operator needs to change the position of the handle and re-fix the handle, which takes a long time to complete the drilling work, thus reducing work efficiency. Therefore, an automatic luggage handle drilling device is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic luggage handle punching device is designed, comprising a base plate, a first box, and a second box. Two first boxes are provided above the base plate, and a second box is provided above the first boxes. Each of the first boxes is provided with a limiting mechanism, and each of the second boxes is provided with an adjusting mechanism. Multiple first vertical plates are fixedly connected above the base plate, and two second vertical plates are fixedly connected to the bottom of the first boxes. The bottom of each of the second vertical plates is fixedly connected to the base plate.

[0006] Preferably, a hydraulic cylinder is provided above the base plate, and a punch head is installed at the output end of the hydraulic cylinder.

[0007] Preferably, the limiting mechanism includes a first motor, with a double-ended stud fixedly connected to the end of the output shaft of the first motor. Both ends of the double-ended stud are rotatably connected to the first housing via bearings. The outer walls of the double-ended stud are threadedly connected to the slider on both sides. The front side of the slider is movably connected to a connecting rod via a pin. The lower part of the connecting rod is movably connected to a pressure block via a pin. The inner wall of the pressure block is slidably connected to two first fixed posts. Both ends of the first fixed posts are fixedly connected to the base plate and the first housing, respectively. Both sides of the turntable drive shaft are rotatably connected to the fixed block via bearings. The turntable and the fixed block are connected by bolts. A handle is fixedly connected to the right end of the turntable drive shaft.

[0008] Preferably, the ends of the first motor are fixedly connected to the first housing, and the upper end of the base plate is fixedly connected to two fixing blocks.

[0009] Preferably, the adjusting mechanism includes a second motor, with a worm gear fixedly connected to the end of the output shaft of the second motor. Both ends of the worm gear are rotatably connected to the second housing via bearings. The worm gear meshes with a worm wheel. The rear side of the worm wheel drive shaft is rotatably connected to the second housing via bearings. A rotating rod is fixedly connected to the front side of the worm wheel drive shaft. A cylinder is fixedly connected to the lower front side of the rotating rod. The outer wall of the cylinder is slidably connected to the inner wall of a groove machined above the moving block. The inner wall of the moving block is slidably connected to a second fixed column. Both ends of the second fixed column are fixedly connected to the second housing. The bottom of the moving block is fixedly connected to the end of a hydraulic cylinder.

[0010] Preferably, the end of the second motor is fixedly connected to the inner wall of the second housing, and the top of the first vertical plate is fixedly connected to the second housing.

[0011] The present invention proposes an automatic bag handle punching device, the advantages of which are as follows: through the cooperation of the first housing and the limiting mechanism, the output shaft of the first motor rotates, driving the double-headed stud to rotate, thereby driving the two sliders to move synchronously. The movement of the sliders drives the connecting rod to move, thereby driving the pressure block to slide along the outer wall of the first fixed column. The rotation of the handle drives the turntable to rotate. When the groove on the turntable rotates to match the shape of the bag handle, the bolt is rotated, so that the bolt is screwed into the fixed block and the turntable. Thus, through the cooperation of the turntable and the pressure block, bag handles of different shapes can be fixed within a certain range, thereby reducing the limitations of the work.

[0012] Through the cooperation of the second housing and the adjustment mechanism, the output shaft of the second motor swings to drive the worm gear to rotate, which in turn drives the worm wheel to rotate. The rotation of the worm wheel drives the rotating rod to rotate, which in turn drives the cylinder to slide along the groove machined above the moving block. This, in turn, drives the moving block to slide along the outer wall of the second fixed column. This allows the position of the punch head to be automatically adjusted when drilling is required at other horizontal positions of the luggage handle. This eliminates the need for operators to manually re-fix the luggage handle and allows the drilling work at other horizontal positions of the luggage handle to be completed in a shorter time, thereby improving work efficiency.

[0017] The limiting mechanism 4 includes a first motor 401. A double-ended stud 402 is fixedly connected to the end of the output shaft of the first motor 401. Both ends of the double-ended stud 402 are rotatably connected to the first housing 5 via bearings. The outer sides of the double-ended stud 402 are threadedly connected to the slider 403. A connecting rod 404 is movably connected to the front side of each slider 403 via a pin. The lower part of each connecting rod 404 is movably connected to a pressure block 405 via a pin. The inner wall of the pressure block 405 is slidably connected to two first fixed posts 406. Both ends are fixedly connected to the base plate 1 and the first housing 5 respectively. Both sides of the drive shaft of the turntable 407 are rotatably connected to the fixed block 2 through bearings. The turntable 407 and the fixed block 2 are connected by bolts 408. The right end of the drive shaft of the turntable 407 is fixedly connected to the handle 11. The output shaft of the first motor 401 rotates to drive the double-headed stud 402 to rotate, thereby driving the two sliders 403 to move synchronously. The movement of the sliders 403 drives the connecting rod 404 to move, thereby driving the pressure block 405 to slide along the outer wall of the first fixed column 406.

[0018] The adjusting mechanism 6 includes a second motor 601. A worm gear 602 is fixedly connected to the end of the output shaft of the second motor 601. Both ends of the worm gear 602 are rotatably connected to the second housing 8 via bearings. The worm gear 602 meshes with a worm wheel 603. The rear side of the drive shaft of the worm wheel 603 is rotatably connected to the second housing 8 via bearings. A rotating rod 604 is fixedly connected to the front side of the drive shaft of the worm wheel 603. A cylinder 605 is fixedly connected to the lower front side of the rotating rod 604. The outer wall of the cylinder 605 slides against the inner wall of the groove machined above the moving block 606. The movable block 606 is slidably connected to the inner wall of the second fixed column 607. Both ends of the second fixed column 607 are fixedly connected to the second housing 8. The bottom of the movable block 606 is fixedly connected to the end of the hydraulic cylinder 9. The output shaft of the second motor 601 swings to drive the worm gear 602 to rotate, which in turn drives the worm wheel 603 to rotate. The rotation of the worm wheel 603 drives the rotating rod 604 to rotate, which in turn drives the cylinder 605 to slide along the groove machined above the movable block 606, thereby driving the movable block 606 to slide along the outer wall of the second fixed column 607.

[0019] Working principle: When using a punching device to punch holes in the handle of a luggage: The process of securing the luggage handle: The operator first selects a suitable groove on the turntable 407 according to the shape of the luggage handle, and rotates the handle 11. The rotation of the handle 11 drives the turntable 407 to rotate. When the groove on the turntable 407 rotates to match the shape of the luggage handle, the operator rotates the bolt 408 so that the bolt 408 is screwed into the fixing block 2 and the turntable 407, thereby fixing the turntable 407. Then, the power supply of the two first motors 401 is turned on. The output shaft of the first motor 401 rotates forward, driving the double-headed stud 402 to rotate, thereby driving the two sliders 403 to move synchronously. The movement of the sliders 403 drives the connecting rod 404 to move, thereby driving the pressure block 405 to slide downward along the outer wall of the first fixing post 406. When the bottom of the two pressure blocks 405 is pressed against the luggage handle, the power supply of the two first motors 401 is turned off. This allows the turntable 407 and the pressure block 405 to be used to fix luggage handles of different shapes within a certain range, thereby reducing the limitations of the work.

[0020] The process of drilling holes in luggage handles: Hydraulic cylinder 9 is activated, and its output end extends to drive the punch head 10 to punch holes in the luggage handle, enabling automatic punching of the luggage. When punching is required at the location of the luggage handle, the operator activates the power supply to the second motor 601. The output shaft of the second motor 601 rotates, driving the worm gear 602 to rotate, which in turn drives the worm wheel 603 to rotate. The rotation of the worm wheel 603 drives the rotating rod 604 to swing, thereby causing the cylinder 605 to slide along the groove machined above the moving block 606, and further driving the moving block 606 along the second fixed... The outer wall of the fixed column 607 slides. The operator controls the first motor 601 to drive the rotating rod 604 to swing left and right. The worm gear 603 and worm 602 have a self-locking function, so the rotating rod 604 does not need to rotate one revolution. When the output shaft of the first motor 601 rotates forward, it drives the moving block 606 to move to the right. Conversely, when it rotates backward, the moving block 606 moves to the left. The movement of the moving block 606 drives the hydraulic cylinder 9 to move, which in turn drives the punch head 10 to move horizontally. When the punch head 10 moves to another horizontal position where drilling is required, the power of the first motor 601 is turned off. Then, the hydraulic cylinder 9 is restarted to drive the punch head 10 to make holes. There is no need for the operator to fix the bag handle again. The punching work in other horizontal positions can be completed in a short time, thereby improving work efficiency. After the punching is completed, the operator controls the hydraulic cylinder 9 to drive the punch head 10 to reset. Then the operator starts the power supply of the two first motors 401. The output shaft of the first motor 401 reverses to drive the two pressure blocks 405 to reset. Then the operator can take out the bag handle with the holes and then manually clean up the debris from the punching process.
