Description

Technical Field

[0001] The present invention relates to the field of luggage production, and in particular to a luggage frame drilling device. Background Art

[0002] Metal luggage frames are a crucial component of luggage, serving as the bag's skeleton. They support, shape, and protect the contents. Because the frames require through-holes for mounting and connection, current drilling equipment generates significant amounts of debris and dust during operation. This debris scatters, negatively impacting the processing environment and precision. Furthermore, after drilling, burrs and other issues often develop on the edges of the frames, requiring manual removal to prevent disruption to subsequent assembly.

[0003] Current luggage frame production lines generally disperse processes such as punching, cleaning, and polishing to independent workstations. This split process layout leads to reduced efficiency in production process connections, which in turn has an adverse impact on overall production efficiency. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art.

[0005] The present application provides a bag frame drilling device, which includes a drilling mechanism, a waste chip collection mechanism, and a grinding mechanism. The drilling mechanism is used to drill holes in the bag frame. The waste chip collection mechanism is arranged next to the drilling mechanism and is used to collect waste chips and dust generated during the grinding and drilling process. The grinding mechanism is used to grind the edges after drilling. The drilling mechanism, waste chip collection mechanism, and grinding mechanism are integrated in the same chassis.

[0006] It also includes an upper lifting plate, a lifting sleeve, a lower lifting plate and a transmission sleeve. The drilling mechanism is installed on the upper lifting plate, the grinding mechanism is arranged on the lower lifting plate, the lifting sleeve is fixed on the bottom of the upper lifting plate, and the transmission sleeve is coordinated with the lifting sleeve and the lower lifting plate. The transmission sleeve is controlled to rotate by a rotary drive unit, driving the lifting sleeve and the lower lifting plate to rise and fall in sequence.

[0007] An annular groove is provided on the outer peripheral wall of the transmission sleeve, and the annular groove includes a sinking section, an ascending section and an intermediate section connected end to end. The transmission sleeve is rotatably installed in the inner cavity of the chassis through a bearing frame. A sliding block that slides with the annular groove is fixed on the inner wall, and a pair of notches are symmetrically fixed at the lower end. A pair of top blocks are provided on the top surface of the lower lifting plate. Both ends of each notch and each top block are inclined structures. When the sliding block enters the rear section of the ascending section, each top block disengages from the corresponding notch.

[0008] The drilling mechanism comprises a drill and a drill bit. The drill is mounted on the upper lifting plate, and the drill bit passes through the lifting sleeve and the lower lifting plate and extends out of the chassis.

[0009] The grinding mechanism includes a rotating table rotatably mounted at the bottom of the chassis and driven to rotate by a second rotation drive unit. A through hole is provided in the center of the rotating table, and a plurality of slide grooves are provided at intervals on the peripheral wall of the through hole. A lifting frame is movably installed in each slide groove. The upper end of each lifting frame is tightly pressed against the bottom surface of the lower lifting plate, and the lower end extends out of the chassis and is connected to a grinding head. An inclined groove is provided in each slide groove, and a slider that slides in cooperation with the corresponding inclined groove is fixed on the side wall of each lifting frame.

[0010] The grinding mechanism also includes an annular groove arranged on the top surface of the rotating table, in which a lifting sleeve is installed in a floating manner by a spring. The upper end of each lifting frame is bent outward and abuts against the top surface of the lifting sleeve. The spring is used to provide elastic force for the lifting frame to rise and reset.

[0011] The polishing mechanism further includes a micro switch, which is fixed on the inner wall of the chassis, located below the lower lifting plate, and electrically connected to the rotary drive unit.

[0012] The first and second rotary drive units each include a motor, a pulley, a belt ring groove, and a transmission belt. The motor is fixed on the chassis, a pulley is fixedly mounted on the output shaft, the belt ring groove is arranged on the peripheral wall of the transmission sleeve or the rotating table, and the transmission belt is simultaneously sleeved on the outside of the pulley and in the belt ring groove.

[0013] The waste collection mechanism includes an outer cover arranged at the bottom of the chassis, an inner cover is provided in a floating sleeve in the outer cover, the top of the inner cover is fixedly connected to the lower lifting plate through a number of vertical rods passing through the bottom of the chassis, and a negative pressure collection component is connected to the outer cover through a pipe.

[0014] The negative pressure collection assembly includes a collection box, a connecting pipe, a drawer, a filter and an air pump. The filter is fixed in the inner cavity of the collection box. A notch is provided at the lower outer part of the collection box. The drawer is inserted into the collection box through the notch. The air inlet end of the air pump is connected to the top of the inner cavity of the collection box. One end of the connecting pipe is connected to the inner wall of the outer cover, and the other end extends into the inner cavity of the collection box.

[0015] The beneficial effects of the present invention are as follows:

[0016] The present invention integrates the drilling mechanism, waste chip collection mechanism, and grinding mechanism into the same chassis, realizing the continuous operation of drilling, cleaning, grinding and other processes on the same device, avoiding the problem of low production efficiency caused by the existing production line dividing each process into multiple workstations, greatly improving production efficiency, and reducing the occupation of production space and labor intensity.

[0017] The setting of the waste chip collection mechanism can effectively collect waste chips and dust generated during the drilling and grinding process, prevent them from being scattered everywhere, improve the processing environment, protect the health of operators, and also improve the processing accuracy and quality of luggage.

[0018] The grinding mechanism can promptly grind the edges after drilling, effectively removing burrs and rough edges, ensuring the subsequent assembly quality of the frame and avoiding problems such as assembly difficulties and instability caused by burrs and rough edges.

[0019] Through the clever mechanical structure design, the rotation of the transmission sleeve drives the lifting sleeve and the lower lifting plate to rise and fall in sequence, thus realizing the orderly progress of the drilling and grinding processes, with a compact structure and reliable operation.

[0020] The negative pressure collection component adopts a drawer-type design, which is convenient for cleaning the collected waste and dust. The setting of the filter prevents the dust from damaging the vacuum pump and extends the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0029] The following describes in detail the bag frame drilling device provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, an embodiment of the present application provides a drilling device for a luggage frame 100, which includes a drilling mechanism 1, a waste collection mechanism 2, and a grinding mechanism 3. The drilling mechanism 1 is used to drill holes in the luggage frame 100, and the waste collection mechanism 2 is arranged next to the drilling mechanism 1, for collecting waste chips and dust generated during the grinding and drilling process. The grinding mechanism 3 is used to grind the edges after drilling. The drilling mechanism 1, the waste collection mechanism 2, and the grinding mechanism 3 are integrated in the same chassis 4.

[0032] In this embodiment of the present application, it also includes an upper lifting plate 5, a lifting sleeve 6, a lower lifting plate 7 and a transmission sleeve 8. The drilling mechanism 1 is installed on the upper lifting plate 5, the grinding mechanism 3 is arranged on the lower lifting plate 7, the lifting sleeve 6 is fixed at the bottom of the upper lifting plate 5, and the transmission sleeve 8 is coordinated with the lifting sleeve 6 and the lower lifting plate 7. The transmission sleeve 8 is controlled to rotate by a rotation drive unit 9, driving the lifting sleeve 6 and the lower lifting plate 7 to rise and fall in sequence.

[0033] In this embodiment of the present application, a U-shaped bracket 10 is provided at the bottom of the chassis 4 , and a notch 11 corresponding to the drilling mechanism 1 is provided in the middle of the bracket 10 .

[0034] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the luggage frame 100 that needs to be drilled is inserted into the bracket 10, and then the rotary drive unit 9 is operated to control the rotation of the lifting sleeve 6. At the same time, the drilling device is operated, and the upper lifting plate 5 first descends, driving the lower end of the drilling device to extend into the bracket 10, drilling the luggage frame 100 and then rising, and then driving the lower lifting plate 7 to descend, and the grinding mechanism 3 grinds the surface of the luggage frame 100. At the same time, the waste chip collection structure is operated to collect the waste chips and dust generated during the drilling and grinding process. The rotary drive unit 9 continues to operate until the grinding structure rises and separates from the luggage frame 100, completing the drilling of the luggage frame 100 and timely grinding the edges after drilling, effectively removing burrs and burrs, and ensuring the subsequent assembly quality of the frame.

[0035] Example 2:

[0036] In this embodiment, in addition to the structural features of the aforementioned embodiments, an annular groove 12 is provided on the outer peripheral wall of the transmission sleeve 8. The annular groove 12 includes a sinking section 121, an ascending section 122 and an intermediate section 123 connected end to end. The transmission sleeve 8 is rotatably installed in the inner cavity of the chassis 4 through a bearing frame 13. A sliding block 14 that slides with the annular groove 12 is fixed on the inner wall, and a pair of notches 15 are symmetrically fixed at the lower end. A pair of top blocks 16 are provided on the top surface of the lower lifting plate 7. Both ends of each notch 15 and each top block 16 are inclined structures. When the sliding block 14 enters the rear section of the ascending section 122, each top block 16 disengages from the corresponding notch 15.

[0037] In this embodiment of the present application, the drilling mechanism 1 includes a drill rig 101 and a drill bit 102 . The drill rig 101 is installed on the upper lifting plate 5 , and the drill bit 102 passes through the lifting sleeve 6 and the lower lifting plate 7 and extends out of the chassis 4 .

[0038] In this embodiment of the present application, the cross-section of the inner cavity of the chassis 4 is rectangular, the cross-sectional shapes of the upper lifting plate 5 and the lower lifting plate 7 are adapted to the inner cavity of the chassis 4, and the outer peripheral wall slides with the inner wall of the inner cavity of the chassis 4.

[0039] like Figure 1 and Figure 2As shown, due to the adoption of the above-mentioned structure, when the transmission sleeve 8 rotates, the sliding block 14 slides from the middle section 123 to the top of the sinking section 121, and each top block 16 slides to the other end of the corresponding notch 15, and the lifting sleeve 6 descends together with the upper lifting plate 5. Accordingly, the drill rig 101 and the drill bit 102 also descend at the same time, and the drill bit 102 extends into the bracket 10 to drill the bag frame 100 in the bracket 10. The transmission sleeve 8 continues to rotate under the drive of the rotation drive unit 9, and the sliding block 14 enters the rising section 122. The lifting sleeve 6, the upper lifting plate 5, the drill rig 101 and the drill bit 102 are lowered together. As the sliding block 14 slides toward the other end of the ascending section 122, each top block 16 slides out of the corresponding notch 15. Both ends of each top block 16 and both ends of the corresponding notch 15 are inclined surfaces. When each top block 16 slides out of the corresponding notch 15, the lower lifting plate 7 is pushed down, and the grinding structure descends and runs to grind the edge of the frame after drilling. The rotary drive unit 19 continues to run, and each top block 16 enters the notch 15 in the rotation direction. The grinding structure rises, and then the sliding block 14 enters the middle section 123, and the drilling structure descends. After completing the drilling and grinding of the luggage frame 100, it is reset.

[0040] Example 3:

[0041] In this embodiment, in addition to the structural features of the aforementioned embodiments, the grinding mechanism 3 includes a rotating table 32 rotatably mounted on the bottom of the chassis 4 and driven to rotate by a second rotation drive unit 31. A through hole 33 is provided in the center of the rotating table 32, and a plurality of slide grooves 34 are provided on the peripheral wall of the through hole 33. A lifting frame 35 is movably installed in each slide groove 34. The upper end of each lifting frame 35 is tightly pressed against the bottom surface of the lower lifting plate 7, and the lower end extends out of the chassis 4 and is connected to a grinding head 36. Each slide groove 34 is provided with an inclined groove 37, and the side wall of each lifting frame 35 is fixed with a slider 38 that slides with the corresponding inclined groove 37.

[0042] In this embodiment of the present application, the grinding mechanism 3 also includes an annular groove 39 arranged on the top surface of the rotating table 32, and a lifting sleeve 311 is floatingly installed in the annular groove 39 through a spring 310. The upper end of each lifting frame 35 is bent outward and abuts against the top surface of the lifting sleeve 311. The spring 310 is used to provide an elastic force for the lifting frame 35 to rise and reset.

[0043] In this embodiment of the present application, the grinding mechanism 3 further includes a micro switch 312 , which is fixed on the inner wall of the chassis 4 , located below the lower lifting plate 7 , and is electrically connected to the second rotation drive unit 31 .

[0044] In this embodiment of the present application, the rotation drive unit 1 9 and the rotation drive unit 2 31 both include a motor 91, a pulley 92, a belt ring groove 93 and a transmission belt 94. The motor 91 is fixed on the chassis 4, and the pulley 92 is fixedly mounted on the output shaft. The belt ring groove 93 is arranged on the peripheral wall of the transmission sleeve 8 or the rotating table 32, and the transmission belt 94 is simultaneously sleeved on the outside of the pulley 92 and in the belt ring groove 93.

[0045] like Figure 1 、 Figure 3 and Figure 4 As shown, due to the aforementioned structure, when the lower lift plate 7 descends driven by the transmission sleeve 8, its bottom surface abuts against the upper end of the lift frame 35, forcing the lift frame 35 to slide downward along the chute 34 of the rotating table 32. Because the chute 34 is provided with an inclined groove 37, the slider 38 on the side wall of the lift frame 35 moves along the track of the inclined groove 37, causing the grinding head 36 at the lower end of the lift frame 35 to gradually approach the drilled edge of the bag frame 100. At this time, the rotary drive unit 2 31 (e.g., the motor 91 via the pulley 92 and transmission belt 94) drives the rotating table 32, and the grinding head 36 rotates synchronously with the rotating table 32, grinding away the burrs and rough edges of the drilled hole.

[0046] The lifting sleeve 311 is floatingly mounted in the annular groove 39 on the top surface of the rotating table 32 by a spring 310. Its function is to provide a restoring elastic force for the lifting frame 35: when the grinding process is completed and the lower lifting plate 7 rises and separates from the lifting frame 35, the spring 310 pushes the lifting sleeve 311 to move upward, driving the bent portion at the upper end of the lifting frame 35 to rise synchronously, so that the grinding head 36 is restored to its initial position along the inclined groove 37 to avoid contact with the luggage frame 100.

[0047] The setting of the micro switch 312 realizes precise control of the grinding action: when the lifting sleeve 6 drives the lower lifting plate 7 to descend to the preset position, the lower lifting plate 7 triggers the micro switch 312, and the micro switch 312 sends a start signal to the rotation drive unit 2 31, and the rotary table 32 starts to rotate and drives the grinding head 36 to work; when the grinding is completed and the lower lifting plate 7 rises to out of the sensing range of the micro switch 312, the rotation drive unit 2 31 stops running, ensuring the timing coordination of the grinding process and the drilling process.

[0048] Example 4:

[0049] In this embodiment, in addition to the structural features of the aforementioned embodiments, the waste collection mechanism 2 includes an outer cover 21 arranged at the bottom of the chassis 4, and an inner cover 22 is floatingly sleeved in the outer cover 21. The top of the inner cover 22 is fixedly connected to the lower lifting plate 7 through a number of vertical rods passing through the bottom of the chassis 4, and a negative pressure collection assembly 23 is connected to the outer cover 21 through a pipe.

[0050] In this embodiment of the present application, the negative pressure collection assembly 23 includes a collection box 231, a connecting pipe 232, a drawer 233, a filter 234 and an exhaust fan 235. The filter 234 is fixed in the inner cavity of the collection box 231. A notch 11 is provided at the lower outer part of the collection box 231. The drawer 233 is inserted into the collection box 231 from the notch 11. The air inlet end of the exhaust fan 235 is connected to the top of the inner cavity of the collection box 231. One end of the connecting pipe 232 is connected to the inner wall of the outer cover 21, and the other end extends into the inner cavity of the collection box 231.

[0051] like Figure 1 As shown, due to the adoption of the above-mentioned structure, the waste chips and dust generated during the grinding process are collected in real time under the action of the negative pressure collection assembly 23. Specifically, the inner cover 22 is fixed to the lower lifting plate 7 through a vertical rod, and rises and falls synchronously with the lower lifting plate 7, exposing the opening of the connecting pipe 232. The inner cover 22 and the outer cover 21 are connected by an annular sealing ring to achieve floating sealing cooperation, ensuring that a local enclosed space is formed in the processing area, and ensuring that a local enclosed space is formed in the processing area (at the notch 11 of the bracket 10). After the vacuum pump 235 is started, a negative pressure is formed at the top of the inner cavity of the collection box 231, and the waste chips and dust are sucked into the connecting pipe 232 through the gap between the inner cover 22 and the outer cover 21, and enter the collection box 231 through the connecting pipe 232.

[0052] The filter 234 is fixed horizontally within the inner cavity of the collection box 231, trapping waste chips and dust below the filter 234. Clean air passes through the filter 234 and is discharged through the exhaust fan 235. The drawer 233 on the outside of the collection box 231 can be pulled out along the notch 11, facilitating the centralized cleaning of accumulated waste chips and dust. The filter 234 is removable (e.g., a snap-on connection) to facilitate regular maintenance. The combination of the servo-operated design of the inner cover 22 and negative pressure suction effectively prevents the spread of waste chips and dust in the processing area, ensuring a clean operating environment and the health of operators, while also preventing waste chips from clogging drill holes or affecting grinding accuracy.

[0053] When the drilling mechanism 1 completes drilling and rises with the upper lifting plate 5, the transmission sleeve 8 continues to rotate, the sliding block 14 enters the rear section of the rising section 122 of the annular groove 39, the top block 16 disengages from the notch 15 and pushes the lower lifting plate 7 down, driving the grinding mechanism 3 and the inner cover 22 to descend synchronously. At this time:

[0054] The rotating table 32 of the grinding mechanism 3 rotates under the drive of the second rotary drive unit 31, and the grinding head 36 follows the track of the inclined groove 37 close to the edge of the drill hole to complete the burr grinding;

[0055] The inner cover 22 is lowered along with the lower lifting plate 7 until it is in contact with the surface of the bag frame 100. The sealed space formed by the outer cover 21 and the inner cover 22 absorbs the waste dust generated by drilling and grinding through the negative pressure collection component 23;

[0056] When the grinding is completed, the transmission sleeve 8 rotates until the sliding block 14 enters the middle section 123, and the lower lifting plate 7 rises and resets under the action of the spring 310 of the jacking sleeve 311, the inner cover 22 rises synchronously, and the grinding head 36 leaves the frame surface and waits for the next processing cycle.

[0057] Through the above structural design, the three processes of drilling, grinding and waste collection are automatically linked in the same chassis 4, which significantly improves the processing efficiency and quality of the luggage frame 100 and avoids the positioning error and time loss caused by traditional multi-station transfer.

[0058] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved.
