DETAILED DESCRIPTION

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] like Figure 1-3 As shown, a hole-punching device for a transport packaging pallet comprises a frame 1, a gantry 2, a slide 3, a lifting block 4 and a plurality of drilling rig components 5 parallel to the Z-axis direction; wherein the gantry 2 is slidably mounted on the top of the frame 1 along the X-axis direction, the slide 3 is slidably mounted on the upper part of the gantry 2 along the Y-axis direction, and the lifting block 4 is slidably mounted on one side of the slide 3 along the Z-axis direction; the drilling rig component 5 is slidably mounted on one side of the lifting block 4, and each drilling rig component 5 can be lifted and lowered relative to the lifting block 4 along the Z-axis direction.

[0024] Specifically, a gantry 2 is arranged on the top of the frame 1, a slide 3 is arranged on the upper part of the gantry 2, a lifting block 4 is installed on one side of the slide 3, and the gantry 2, the slide 3 and the lifting block 4 can move independently along the X-axis, Y-axis and Z-axis directions respectively, and a plurality of drilling rig components 5 are arranged on the lifting block 4, and the plurality of drilling rig components 5 can all move independently relative to the lifting block 4 along the Z-axis direction.

[0025] The drilling assembly 5 includes a driving motor and a drill bit installed at the output end of the driving motor. The drill bit is driven to rotate by the motor, and as the lifting block 4 moves downward, the hole opening work on the pallet is completed. Since the pallet is designed with holes of different specifications, the drill bit of each drilling assembly 5 is different and is installed according to needs.

[0026] Furthermore, the lifting block 4 is provided with first telescopic components 51 corresponding to the number and position of the drilling components 5, the output end of the first telescopic component 51 is connected to the drilling component 5, and the drilling component 5 and the lifting block 4 are slidably connected via a first slide rail 52. The structure of using the first telescopic component 51 for driving and the first slide rail 52 for guiding is not only convenient and can realize rapid maneuvering, but also cheap and can effectively reduce the implementation cost.

[0027] The working process of the above device:

[0028] First, the gantry 2 and the slide 3 are moved along the X-axis and Y-axis directions respectively, so that the drill bit of one of the drilling rig components 5 is aligned with the position where a hole needs to be drilled;

[0029] The drilling assembly 5 is started, and the drilling assembly 5 moves downward relative to the lifting block 4 along the Z-axis direction;

[0030] The lifting block 4 moves downward to make a hole in the tray;

[0031] After this process is completed, the lifting block 4 moves upward, and at the same time, the drilling assembly 5 also moves upward and retracts into the range of the lifting block 4, and the above steps (1), (2), and (3) are repeated again.

[0032] The above device can achieve the purpose of clamping once and drilling multiple times, which is convenient for centralizing the working procedures, thereby reducing the number of times the pallet is transported and improving the efficiency of drilling.

[0033] Among them, regarding the independent movement of the gantry 2, the slide 3 and the lifting block 4 along the X, Y and Z axis directions respectively, it is a common existing technology, usually adopting the principle of screw and nut transmission, such as a screw rod 41 installed on one side of the slide 3, which is parallel to the Z axis and screwed through the lifting block 4, and at the same time, two guide rods parallel to the screw rod 41 are passed through the lifting block 4 to achieve the purpose of limiting and guiding, which will not be elaborated here.

[0034] like Figure 1 , Figure 5 As shown, the frame 1 includes two brackets 11 arranged opposite to each other, a plurality of connecting rods 12 parallel to the Y-axis direction are arranged between the two brackets 11, the plurality of connecting rods 12 are distributed at equal intervals, and the gantry 2 is slidably mounted on the brackets 11.

[0035] The two ends of the connecting rod 12 are fixedly mounted on the two brackets 11 by screws and other connecting parts. There is a gap between the connecting rods 12, which is not only convenient for installing some other components, but also convenient for discharging the wood chips generated by the opening to the bottom of the connecting rod 12, which is convenient for subsequent centralized collection and processing.

[0036] As mentioned above, a connecting plate 13 is fixedly installed between the same ends of the two brackets 11 close to the drilling assembly 5, and a positioning plate 8 capable of being lifted and lowered along the Z-axis direction is provided on one side of the connecting plate 13.

[0037] Specifically, a second telescopic component 81 is installed on the connecting plate 13, and the output end of the second telescopic component 81 is parallel to the Z-axis direction and connected to the positioning plate 8; a second slide rail 82 parallel to the Z-axis direction is also fixedly installed on the connecting plate 13, and a slider 83 is fixedly installed on the positioning plate 8, and the slider 83 is slidably connected to the second slide rail 82.

[0038] The first telescopic assembly 51 and the second telescopic assembly 81 preferably use cylinders, which have a simple structure and can quickly and effectively complete the telescopic driving work.

[0039] like Figure 1 , Figure 4 As described above, two clamping plates 6 are relatively arranged on the top of the frame 1 and are parallel to the X-axis direction, and the two clamping plates 6 can be synchronously moved horizontally to the middle position of the frame 1. This structure can realize the automatic centering operation of the pallet, thereby improving the accuracy of the hole opening and facilitating the positioning of the drilling assembly 5.

[0040] As mentioned above, the clamping plate 6 is located above the connecting rod 12, and the frame 1 is also provided with a driving mechanism 7 for driving the two clamping plates 6 to move.

[0041] The driving mechanism 7 includes a plurality of transmission components, and the plurality of transmission components are equidistantly spaced apart; each transmission component includes two sprockets 71 and a transmission chain 72 fitted on the two sprockets 71, the two sprockets 71 are rotatably mounted on two brackets 11, and the transmission chain 72 is located at the interval of the connecting rod 12; one of the splints 6 is connected to the upper side of the transmission chain 72 through a first connecting member 61, and the other splint 6 is connected to the lower side of the transmission chain 72 through a second connecting member 62.

[0042] Specifically, the transmission chain 72 is a closed-loop structure, and its two sprockets 71 are respectively installed at its two ends. When the entire transmission assembly moves, the upper and lower sides of the transmission chain 72 have different movement directions, that is, they move towards each other or move away from each other; based on this, the two splints 6 are respectively connected to the upper and lower sides of the transmission chain 72 through the first connecting member 61 and the second connecting member 62. In this way, under the support and drive of multiple transmission components, the two splints 6 can be synchronously moved horizontally to the middle position of the frame 1.

[0043] Furthermore, the driving mechanism 7 also includes two transmission shafts 73, which are rotatably mounted on the two brackets 11 respectively. The transmission shafts 73 pass through a plurality of sprockets 71 in sequence, and one end of one of the transmission shafts 73 is fixedly connected to the output end of the motor.

[0044] As mentioned above, the sprocket 71 on the same side of each transmission assembly is driven by a transmission shaft 73, which passes through multiple sprockets 71 in sequence and is fixed thereto to achieve synchronous movement; that is, under the drive of the motor, the transmission shaft 73 can drive the sprocket 71 on the same side to rotate synchronously, and the sprocket 71 on the other side acts as a driven shaft and driven wheel to follow the former.

[0045] Working principle:

[0046] (1) X-axis positioning: The tray to be drilled is placed on the connecting rod 12 of the frame 1. Driven by the second telescopic assembly 81, the positioning plate 8 rises along the second slide rail 82 in the Z-axis direction until it is higher than the upper top surface of the connecting rod 12. Then, one side of the tray is manually pressed against the side of the positioning plate 8 to complete its positioning in the X-axis direction.

[0047] (2) Y-axis centering: Based on step (1), the motor drives the transmission shaft 73 to rotate, so that the driving mechanism 7 drives the two clamping plates 6 to move horizontally along the Y-axis to the middle position of the frame 1 until the inner sides of the two clamping plates 6 are tightly fitted with the side surfaces of the tray, thereby completing the positioning and clamping of the workpiece; then the positioning plate 8 is reset under the drive of the second telescopic component 81;

[0048] (3) Drilling: Driven by the gantry 2 and the slide 3, the lifting block 4 aligns the required drilling assembly 5 with the drilling position in the XOY horizontal plane. At the same time, driven by the first telescopic assembly 51, the drilling assembly 5 moves downward along the first slide rail 52 relative to the lifting block 4, and its drill bit starts to rotate; then the lifting block 4 moves downward along the Z axis, so that the drill bit drills into the interior of the tray; after this process is completed, the lifting block 4 moves upward, and the drilling assembly 5 also moves upward and retracts into the range of the lifting block 4; then another drilling assembly 5 is replaced for subsequent processing of the hole or for drilling holes of other specifications, and step (3) is repeated until the drilling of the tray is completed.

[0049] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
