However, the surface hole drilling device for refrigerator plastic pallets in the prior art cannot adaptively fix the refrigerator plastic pallets according to the specifications of the refrigerator plastic pallets that need to be processed, thereby reducing the hole drilling efficiency of the refrigerator plastic pallet surface. It is also difficult to accurately and quickly adjust the hole opening position on the surface of the refrigerator plastic pallet according to actual needs, thereby reducing the quality of the products produced and work efficiency.

[0004] In the prior art, a Chinese patent with publication number CN220864203U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a refrigerator plastic pallet surface opening device is used to solve the technical problem that the refrigerator plastic pallet surface opening device in the prior art cannot be adaptively fixed according to the specifications of the refrigerator plastic pallet to be processed, thereby reducing the technical problem of opening holes on the surface of the refrigerator plastic pallet. The device comprises a base, a support leg is provided at the corner of the bottom of the base, and a fixing seat is symmetrically provided on the outer wall of the two ends of the top of the base.

Summary of the Invention

A support plate is provided on the top of the adjusting plate, and the surface of the top of the support plate fits the surface of the bottom of the N-shaped pallet. A connecting plate is fixedly installed on the bottom of the support plate, and an adjusting component for adjusting the connecting plate is provided at one end of the adjusting plate.

The tops of the workbenches on both sides of the N-shaped pallet are provided with clamping components for clamping the N-shaped pallet.

[0008] According to the different through-hole diameters that need to be opened on the N-shaped pallet, a motor can be installed to drive the screw to rotate, thereby driving the fixed block and the adjustment plate to slide, and the position of the support plate can be moved and adjusted, so that the through-hole that is slightly larger than or equal to the required hole can be aligned directly under the drill bit, so that the support plate can be used to support the N-shaped pallet in the future and the hole opening operation can be performed on the N-shaped pallet. By setting an adjusting component, the height of the connecting plate can be adjusted, and the height of the support plate can be adjusted so that the support plate can fit with the bottom of the N-shaped pallet, and the N-shaped pallet is supported and limited to prevent deformation and cracking during subsequent hole opening due to a certain gap at the bottom of the N-shaped pallet, thereby improving the effect of hole opening on the N-shaped pallet.

[0009] A further improvement of the technical solution of the present invention is that: the adjusting component includes a movable plate, which is slidably connected to the inner wall of the adjusting plate, and the surface of the other end of the movable plate is provided with an inclined surface inclined toward one end of the top, and the inclined surface is in contact with the surface of one end of the connecting plate. A threaded rod is rotatably installed on one end of the movable plate through a bearing, and the threaded rod is threadedly connected to the inner wall of the adjusting plate, and the threaded rod extends out of one end of the threaded rod and is fixedly installed with a handwheel.

At the same time, by opening a slope at the other end of the movable plate, the connecting plate can be squeezed upward, so that the height of the support plate can be adjusted to ensure that the support plate can support and limit N-shaped pallets of different heights, thereby expanding the scope of application of the device. By installing a handwheel, the contact area between the user's hand and the threaded rod can be expanded to facilitate the rotation of the threaded rod.

[0014] The above-mentioned technical solution is adopted. In this solution, infrared rays can be emitted to the bottom by installing an infrared sensor, and the infrared rays can be received by installing a receiver. In the process of moving the support plate, each receiver can be driven to move. If the receiver at the specified position receives the infrared sensor, the result can be transmitted to the controller, so that it can be determined that the through hole corresponding to the position is just moved to the bottom of the drill bit, ensuring that the drill bit can just extend into the through hole, preventing the position of the hole from shifting and causing the N-shaped pallet to deform and crack, thereby improving the hole opening effect.

[0015] A further improvement of the technical solution of the present invention is that a plurality of indicator lines of different lengths are attached to the top of the support plate on one side of each through hole, and each indicator line is located on the same horizontal line as each through hole.

[0016] The above technical solution is adopted. In this solution, by setting several indicator lines of different lengths, the length of each indicator line corresponds to the actual diameter of the through hole, thereby facilitating the user to quickly determine the distance by which the through hole position needs to be adjusted, so as to facilitate the user's operation.

[0018] The above-mentioned technical solution is adopted. In this solution, by rotating the two screws separately, the two clamps can be driven closer to each other, so that the N-shaped pallet can be clamped and limited from both sides, preventing the N-shaped pallet from shifting during the drilling process and causing deformation and cracking, thereby further improving the effect of subsequent hole opening.

[0019] A further improvement of the technical solution of the present invention is that a plurality of sliders are fixedly installed on both sides of the connecting plate, a plurality of slide grooves matching the shape of each slider are opened inside the adjusting plate, and each slider is slidably connected to each slide groove.

[0020] By adopting the above technical solution, a plurality of sliders are installed to guide and limit the sliding track of the connecting plate, and at the same time, the connecting plate can be prevented from being separated from the top of the adjustment plate and lost, thereby ensuring the integrity of the device.

[0045] Example 2

[0046] like Figure 1 、 Figure 5 and Figure 6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the adjusting component 7 includes a movable plate 701, which is slidably connected to the inner wall of the adjusting plate 6, and the surface of the other end of the movable plate 701 is provided with an inclined surface inclined toward one end of the top, which is in contact with the surface of one end of the connecting plate 15, and one end of the movable plate 701 is rotatably installed with a threaded rod 702 through a bearing, and the threaded rod 702 is threadedly connected to the inner wall of the adjusting plate 6, and the threaded rod 702 extends from one end of the threaded rod 702 and is fixedly installed with a handwheel 703, and a baffle 16 is slidably installed inside the adjusting plate 6 at the other end of the connecting plate 15, and the surface of one end of the baffle 16 is provided with an inclined surface inclined toward the other end of the top, which is in contact with the surface of the other end of the connecting plate 15, and a spring group 1601 is fixedly installed on the other end of the connecting plate 15, and the surface of the other end of the spring group 1601 is fixedly connected to the inner wall of the adjusting plate 6.

At the same time, by providing an inclined surface at the other end of the movable plate 701, the connecting plate 15 can be squeezed upward, so that the height of the support plate 13 can be adjusted, ensuring that the support plate 13 can support and limit the N-shaped pallets 10 of different heights, thereby expanding the scope of application of the device.

[0051] Example 4

[0052] like Figure 3 、 Figure 4 and Figure 6 As shown, based on Example 3, the present invention provides a technical solution: preferably, each clamping component 5 includes a fixed plate 501, each fixed plate 501 is fixedly connected to the top of the workbench 1, and the interior of each fixed plate 501 is threadedly installed with a screw 503, each screw 503 extends to the interior of each fixed plate 501, and is rotatably installed with a splint 502 through a bearing, and a sliding rod 504 is fixedly installed on the outer side of each splint 502 at both ends of each screw 503, and each sliding rod 504 passes through the interior of each fixed plate 501.

[0053] In this embodiment, by rotating the two screws 503 respectively, the two clamps 502 can be driven closer to each other, so that the N-shaped pallet 10 can be clamped and limited from both sides, preventing the N-shaped pallet 10 from shifting during the drilling process and causing deformation and cracking, thereby further improving the effect of subsequent hole drilling.

[0054] The present invention also provides an operating method of a hole-punching device for pallet processing, comprising the following steps:

[0055] S1. Preparatory step: Depending on the actual diameter of the hole required for the tray, the user can select a through hole 1301 that is slightly larger than or equal to the required diameter, and move the through hole 1301 at the top of the support plate 13 to just below the drill bit 8;

[0056] S2, clamping process: the user places the N-shaped tray 10 to be opened on the top of the workbench 1 outside the support plate 13, and then rotates the two screws 503 respectively, which simultaneously drives the two clamping plates 502 to move, thereby clamping and limiting the position of the N-shaped tray 10 from both sides;

[0057] S3, adjustment process, the user can rotate the threaded rod 702, and at the same time drive the top baffle 16 to press the connecting plate 15 upward, and adjust the support plate 13 to a position that fits the bottom of the N-shaped tray 10, thereby supporting the N-shaped tray 10 from the bottom;

[0058] S4, a hole-drilling process, in which the user turns on the drill bit 8 and uses the hydraulic cylinder 12 to move the drill bit 8 downward, thereby using the drill bit 8 to drill a hole in the N-shaped pallet 10;

[0059] S5, blanking process, after all the holes are drilled, the user uses the hydraulic cylinder 12 to drive the drill bit 8 to move upward, so that the drill bit 8 is away from the N-shaped pallet 10, and then rotates the two screws 503 in the opposite direction, while driving the two clamping plates 502 away from the N-shaped pallet 10, and then performs blanking operation on the N-shaped pallet 10 from the top.

[0060] The following specifically describes the working principle of the hole-punching device and operation method for pallet processing.

[0061] like Figures 1-6 As shown, according to the actual size of the hole to be opened in the tray, the user can observe the specific length of the indicator line 1302 corresponding to each through hole 1301, and then select a through hole 1301 slightly larger than or equal to the required hole diameter, and then use the motor 11 to drive the screw rod 1101 to rotate, thereby driving the position of the support plate 13 to move. At this time, the infrared sensor 9 can continuously emit infrared rays. When the receiver 14 at the specified position receives the infrared rays, the controller 4 controls the motor 11 to stop working. At this time, it can be ensured that the through hole 1301 slightly larger than or equal to the required hole is aligned directly under the drill bit 8. The user then places the N-shaped tray 10 that needs to be opened on the top of the workbench 1 outside the support plate 13, and rotates the two screws 503 respectively, thereby driving the two clamping plates 502 closer to each other to clamp the N-shaped tray 10. The user then rotates The handwheel 703 rotates the threaded rod 702, and at the same time drives the movable plate 701 to move toward the other end, squeezing the support plate 13 upward so that it fits with the bottom of the N-shaped pallet 10, supporting and limiting the N-shaped pallet 10, and preventing deformation and cracking during subsequent hole opening due to a certain gap at the bottom of the N-shaped pallet 10, thereby improving the effect of hole opening on the N-shaped pallet 10. After the adjustment is completed, the user can use the hydraulic cylinder 12 to drive the drill bit 8 to move downward, so that the drill bit 8 can be used to perform a hole opening operation on the N-shaped pallet 10. After the hole opening is completed, the user uses the hydraulic cylinder 12 to drive the drill bit 8 upward away from the N-shaped pallet 10, and then rotates the two screws 503 in the opposite direction to make the two clamping plates 502 away from the N-shaped pallet 10, and then removes the N-shaped pallet 10 from the top, thereby completing the hole opening operation on the N-shaped pallet 10.

[0062] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
