Description

Technical Field

[0001] The utility model relates to the technical field of plate drilling, in particular to a packaging box drilling device. Background Art

[0002] In the process of making wooden packaging boxes, there are various ways to fix the boards together. Among them, nailing (steel nails or carpenter nails) may pose a safety hazard due to protruding nails, and it is difficult to disassemble and easy to damage the wood boards. The gluing method affects production efficiency due to the long drying time of the glue, and the glue may contain harmful substances. The mortise and tenon joint method has a complex production process and high cost, which is not suitable for large-scale production. The use of riveting and bolting methods requires pre-drilling of the board.

[0003] Moreover, in order to facilitate opening, existing wooden packaging boxes generally adopt an openable top cover design, so it is necessary to provide a top cover hinge, and it is also necessary to locate the installation position of the hinge and drill holes.

[0004] When drilling, whether it is a fixing hole between panels or a mounting hole for a hinge, accurate positioning is required to reduce rework due to positioning errors.

[0005] In the existing technology, the use of high-precision drilling equipment such as CNC drilling machines can improve drilling accuracy and drilling efficiency, but its use cost is relatively high; when using multi-hole drilling machines, since multi-hole drilling machines can generally only locate a single drilling position, whether it is manual adjustment or motor-assisted adjustment of the position of the positioning plate, it is necessary to frequently change the drilling positioning parameters, which is cumbersome and prone to errors, thus affecting drilling efficiency.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0031] like Figures 1 to 6 In the embodiment of the packaging box drilling device of the present invention shown, the packaging box drilling device includes a drilling machine 100, a drilling rig 200 and a drilling rig frame 300, the drilling rig 200 is arranged above the drilling machine 100, and the drilling rig frame 300 is fixedly arranged on the drilling machine 100; the drilling rig 200 is arranged on the drilling rig frame 300 in a liftable manner, specifically, a lifting device (such as a hydraulic lifter, an electric lifter or a handwheel lifter, etc.) is provided in the drilling rig frame 300, and the drilling rig 200 is fixedly arranged at the output end of the lifting device; the drilling rig 200 can adopt a single-hole drill or a multi-hole drill; a positioning component is provided on the drilling machine 100, and the positioning component is generally two perpendicular positioning rods. After the workpiece to be drilled (such as a wooden board) is placed on the drilling machine 100, the two sides of the board are against the positioning component to achieve positioning. At this time, the drilling rig 200 acts on the workpiece to complete the drilling operation.

[0032] Specifically, such as Figure 1As shown, the drilling machine 100 is provided with a transverse positioning rod 1 and multiple longitudinal positioning rods 2. The longitudinal positioning rod 2 is slidably arranged on the transverse positioning rod 1. The multiple longitudinal positioning rods 2 are all arranged on one side of the transverse positioning rod 1. The multiple longitudinal positioning rods 2 can slide along the length direction of the transverse positioning rod 1 respectively. The transverse positioning rod 1 is arranged between the drilling rig 200 and the drilling rig frame 300; the distance between the transverse positioning rod 1 and the drilling rig 200, and the distance between the longitudinal positioning rod 2 and the drilling rig 200 jointly determine the drilling position of the workpiece.

[0033] More specifically, Figure 2 、 Figure 3 As shown, a sliding bracket 21 is slidingly provided on the transverse positioning rod 1, and the transverse positioning rod 1 is slidingly connected to the longitudinal positioning rod 2 through the sliding bracket 21, and the longitudinal positioning rod 2 is rotationally connected to the sliding bracket 21 through the rotating shaft 22, that is, the longitudinal positioning rod 2 can rotate relative to the sliding bracket 21; in this way, the longitudinal positioning rod 2 can not only slide on the transverse positioning rod 1 through the sliding bracket 21 to adjust the distance between the longitudinal positioning rod 2 and the drilling rig 200, but also can rotate relative to the sliding bracket 21 to complete storage or deployment; after a longitudinal positioning rod 2 close to the drilling rig 200 is completed, it will not affect the workpiece from interfering with other longitudinal positioning rods 2 that have not been stored (i.e. deployed) and are far away from the drilling rig 200.

[0034] More specifically, Figure 4 As shown, a hollow cavity is provided in the longitudinal positioning rod 2 along its length direction, and a push rod 23 and a spring 24 that interfere with each other are provided in the hollow cavity. A bolt that blocks the hollow cavity is provided at one end of the longitudinal positioning rod 2 away from the sliding bracket 21, and the other end of the spring 24 interferes with the bolt, and the spring 24 is always in a compressed state; at the same time, a cam 25 is provided on the outer periphery of the rotating shaft 22 on the sliding bracket 21, and the push rod 23 is affected by the spring 24 and interferes with both sides of the cam 25; an anti-slip texture is provided at one end of the longitudinal positioning rod 2 away from the sliding bracket 21. When the staff operates the anti-slip texture to pull the longitudinal positioning rod 2 to rotate, the push rod 23 will slide on the surface of the cam 25 to slide from one side of the cam 25 to the other side. At this time, the push rod 23 will be affected by the interference of the cam 25 and the spring 24 and first generate a certain resistance, and then the push rod 23 is pushed to the other side of the cam by the spring 24.

[0035] To be more specific, when the push rod 23 abuts against the side of the cam 25 away from the transverse positioning rod 1, the longitudinal positioning rod 2 is parallel to the drilling machine 100 (i.e., it is unfolded and can be used for positioning). This is the result of the longitudinal positioning rod 2 rotating in the direction away from the transverse positioning rod 1; when the push rod 23 abuts against the side of the cam 25 close to the transverse positioning rod 1, the longitudinal positioning rod 2 is perpendicular to the drilling machine 100 (i.e., it is stored and can avoid other longitudinal positioning rods 2). This is the result of the longitudinal positioning rod 2 rotating in the direction close to the transverse positioning rod 1; in the above process, when the longitudinal positioning rod 2 is parallel to the drilling machine 100, the longitudinal positioning rod 2 is attached to the drilling machine 100, so as to effectively make the longitudinal positioning rod 2 abut against the workpiece to complete the positioning.

[0036] According to the above specific content, during the use of the packaging box drilling device of the present invention, multiple longitudinal positioning rods are arranged in the same direction from the drilling rig and thus the positioning parameters of multiple drilling holes can be pre-set. When the positioning parameters of a certain longitudinal positioning rod are not needed, the longitudinal positioning rod can be pulled to be stored so that the workpiece contacts other longitudinal positioning rods to effectively change the positioning parameters. This device has low cost and simple operation, and can effectively improve the efficiency of packaging box drilling.

[0037] In one embodiment of the present application, preferably, Figure 3 As shown, the transverse positioning rod 1 is further provided with a butt plate 11 parallel thereto, and the butt plate 11 isolates the workpiece from the longitudinal positioning rod 2 perpendicular to the drilling machine 100, that is, the surface of the butt plate 11 away from the transverse positioning rod 1 is further away from the transverse positioning rod 1 than the surface of the retracted longitudinal positioning rod 2 away from the transverse positioning rod 1 (the two surfaces in contrast may also be parallel), so that when the workpiece abuts against the butt plate 11, the retracted longitudinal positioning rod 2 will not interfere with the workpiece; the surface of the butt plate 11 away from the transverse positioning rod 1 is set as a plane, so that the workpiece can closely abut against the butt plate 11, which is also more conducive to positioning the workpiece.

[0038] In the above embodiment, if Figure 5 As shown, the support plate 11 is connected to the transverse positioning rod 1 through a sliding bracket 21, and the support plate 11 is fixedly connected to the sliding bracket 21. In this way, the support plate 11 can slide on the transverse positioning rod 1, making the application scenarios of the support plate 11 more flexible and changeable.

[0039] In one embodiment of the present application, preferably, the longitudinal positioning rod 2 (in the expanded state) parallel to the drilling machine 100 is perpendicular to the transverse positioning rod 1, and therefore also perpendicular to the abutment plate 11; at this time, the workpiece can tightly contact the longitudinal positioning rod 2, which is conducive to positioning the workpiece.

[0040] In one embodiment of the present application, preferably, Figure 4As shown, groove surfaces 26 are provided on both sides of the cam 25, and the end of the push rod 23 is set as a dome, which abuts against the groove surface 26. The dome and the groove surface 26 cooperate to enable the longitudinal positioning rod 2 to remain in the stored state or the expanded state.

[0041] In one embodiment of the present application, preferably, Figure 4 As shown, the top surface of the transverse positioning rod 1 is provided with a clamping long groove 12, and a clamping protrusion 211 is fixedly provided on the sliding bracket 21, and the clamping protrusion 211 is slidably provided in the clamping long groove 12; the side of the transverse positioning rod 1 can also be provided with a clamping long groove 12 and a corresponding clamping protrusion 211 is provided on the sliding bracket 21, which can make the sliding of the sliding bracket 21 more stable; the clamping protrusion 211 provided on the top surface of the transverse positioning rod 1 is provided with a handwheel stud 13 that cooperates with its thread, and a handwheel 14 is provided at the top of the handwheel stud 13; manually rotating the handwheel 14 can drive the handwheel bolt 13 to rotate, so that the clamping protrusion 211 contacts the clamping long groove 12 and the handwheel 14 contacts the clamping protrusion 211, thereby making the sliding bracket 21 and the transverse positioning rod 1 relatively fixed.

[0042] In one embodiment of the present application, preferably, Figure 5 As shown, since the sliding bracket 21 fixedly connected to the support plate 11 is located directly below the drilling rig frame 300, there may be a situation where the space is too small to manually rotate the handwheel 14. Therefore, a bolt can be used instead of the handwheel 14 to facilitate the relative fixation between the support plate 11 and the transverse positioning rod 1.

[0043] In one embodiment of the present application, preferably, Figure 6 As shown, a fixing rod 3 is fixed on the drilling machine 100, and the two ends of the transverse positioning rod 1 are movably connected to the two fixing rods 3, so that the transverse positioning rod 1 can slide in the direction away from or close to the drilling rig 200 to adjust the distance between the transverse positioning rod 1 and the drilling rig 200; in addition, a clamping groove 31 is provided on the top surface of the fixing rod 3, and a clamping slider 32 is slidably provided in the clamping groove 31, and the clamping slider 32 is threadedly connected to the handwheel stud 13, and the handwheel stud 13 is passed through the transverse positioning rod 1, and a handwheel 14 is provided on the top of the handwheel stud 13; manually rotating the handwheel 14 can drive the handwheel bolt 13 to rotate, so that the clamping slider 32 contacts the clamping groove 31, and the handwheel 14 contacts the upper surface of the transverse positioning rod 1 (a pad 15 can be provided on the upper surface of the transverse positioning rod 1, so that the handwheel 14 contacts the pad 15), so that the transverse positioning rod 1 and the fixing rod 3 are relatively fixed.

[0044] In the above embodiment, a long round groove is provided between the top surface and the bottom surface of the transverse positioning rod 1, and both sides of the long round groove extend in the length direction of the transverse positioning rod 1, and the handwheel stud 13 is slidably arranged in the long round groove; in this way, the two ends of the transverse positioning rod 1 can slide respectively relative to the fixed rod 3, so that the transverse positioning rod 1 is tilted at a certain angle on the drilling machine to cope with special drilling scenarios.

[0045] In one embodiment of the present application, the transverse positioning rod 1 and the fixing rod 3 may be made of aluminum profiles.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
