Description

Technical Field

[0001] This application relates to the field of cutting equipment technology, specifically a positioning device for cutting panel box plates. Background Technology

[0002] Palletized boxes are used as outer packaging for items during express delivery. They are usually composed of multiple strips of wooden boards, which are connected and fixed together with nails to wrap and protect the items.

[0003] The wooden boards of the pallet box need to be cut using cutting equipment, usually a woodworking circular saw. The circular saw, located on the top of the workbench, cuts the boards to the appropriate size. When cutting the boards, a support is used to hold the boards in place. Then, one hand holds the side of the board away from the support, pressing the board against the support, while the other hand pushes the board towards the circular saw to complete the cut. However, the size cut on the side of the board away from the support is usually too small, which can cause the hand pressing the board to accidentally touch the circular saw during cutting, resulting in hand injury.

[0004] Therefore, this application provides a positioning device for cutting the sheet metal of a panel box to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a positioning device for cutting panel boxes, aiming to solve the problem mentioned in the background art. When cutting panels, one hand holds the side of the panel away from the backrest and presses the panel to fit tightly against the backrest, while the other hand pushes the panel towards the circular saw to complete the cutting. However, the cutting size of the side of the panel away from the backrest is usually too small, which may cause the hand pressing the panel to accidentally touch the circular saw during cutting, resulting in hand injury.

[0006] To achieve the above objectives, this application provides the following technical solution: a positioning device for cutting panel box plates, including a backing, a circular saw for cutting the plate is provided on one side of the backing, and a workbench for installing the circular saw is provided at the bottom of the backing;

[0007] To facilitate pressing the side of the board away from the backing: an adjustment component for adjusting the position of the backing is provided on the side of the backing; a push plate for laterally pushing the board is provided on the side of the circular saw away from the backing; a drive component for pushing the push plate is provided on the side of the push plate away from the circular saw; the drive component includes a push spring symmetrically arranged on the side of the push plate away from the circular saw for pushing the push plate, a guide rod inserted inside the push spring for guiding the movement of the push plate, a limiting plate provided at the end of the guide rod away from the push plate for limiting the movement of the guide rod, and a lifting rod provided on the side of the push plate away from the circular saw for the guide rod to be inserted and connected. Before cutting the board, adjust the distance between the support and the circular saw according to the required cutting size. Then, align one side of the board with the side of the support closest to the circular saw. Next, pull the push plate to move it away from the circular saw, placing the side of the board away from the support on the push plate. Then, release the push plate, and under the restoring force of the push spring, push the push plate closer to the board, thereby squeezing the board and making it fit against the support. When cutting the board, the worker only needs to push the part of the board located between the circular saw and the support, thus avoiding hand injuries from the circular saw.

[0008] Preferably, to facilitate pushing the push plate: both ends of the guide rod are fixedly connected to the push plate and the limiting plate on opposite sides, respectively; the push spring is sleeved on the outer wall of the end of the guide rod away from the limiting plate; one side of the lifting rod has symmetrical through holes for slidingly inserting and connecting the guide rod; and the push spring is disposed between the push plate and the lifting rod. Through the push spring disposed between the push plate and the lifting rod, under the action of the restoring force of the push spring, the push plate is pushed to move the plate closer to the support, achieving close contact between the plate and the support during plate cutting, eliminating the need for manual support and avoiding hand injuries.

[0009] Preferably, to facilitate the snap-fitting of the sheet metal, the vertical cross-section of the push plate is inverted L-shaped. This inverted L-shaped design allows the push plate to snap-fit ​​and adapt to the edges and corners of the sheet metal, facilitating its movement.

[0010] Preferably, to facilitate the adjustment of the push plate height: the bottom end of the lifting rod is provided with a movable component for adjusting the height of the push plate. The movable component includes a lifting screw for adjusting the height of the lifting rod. The top end of the lifting rod has a threaded hole, and the lifting screw is threadedly connected to the threaded hole. A second bearing is sleeved on the outer wall of the bottom of the lifting screw. A fixing plate for mounting the second bearing is fixedly connected to the top end of the worktable. The top end of the fixing plate has a groove for the second bearing to fit. By rotating the lifting screw, the height of the lifting rod is adjusted, thereby driving the guide rod through the lifting rod. The guide rod then causes the height of the push plate to change, thus adapting to plates of different thicknesses.

[0011] Preferably, to prevent the lifting rod from rotating: a limiting hole is provided on one side of the top end of the lifting rod, and a second limiting rod for limiting the rotation of the lifting rod is inserted through the limiting hole. The bottom end of the second limiting rod is fixedly connected to one side of the top end of the fixed plate. By inserting the second limiting rod inside the limiting hole, the rotation of the lifting rod is restricted, and it can only move vertically.

[0012] Preferably, to adjust the position of the support: the adjustment assembly includes an adjusting screw for moving the support, a first bearing sleeved on the outer wall of the adjusting screw end for maintaining the rotation of the adjusting screw, and a first limiting rod symmetrically arranged on the side of the support away from the circular saw for limiting the rotation of the support. By rotating the adjusting screw, the lateral position of the support can be adjusted, thereby cutting plates of different sizes.

[0013] Preferably, for the installation of the adjusting screw and the first limiting rod: a first mounting plate and a second mounting plate are fixedly connected to the top of the worktable to support the adjusting screw and the first limiting rod. One side of the first mounting plate has a threaded groove for the adjusting screw to thread through, and one side of the second mounting plate has a through groove for the first limiting rod to slide through. The side of the support away from the circular saw has a circular groove for installing the first bearing. The adjusting screw is threaded through the first mounting plate, and the first limiting rod slides through the second mounting plate, thereby maintaining the horizontal movement of the support.

[0014] This application utilizes the design of a push plate, drive assembly, and moving parts. By pushing the push plate with a spring, the push plate and the backing plate work together to clamp the sheet metal. Thus, when cutting the sheet metal, the operator only needs to hold the part of the sheet metal located between the backing plate and the circular saw, without having to press down on the part of the sheet metal away from the backing plate with their hands. This avoids hand injuries from the circular saw when pressing down. At the same time, the height of the lifting rod can be adjusted by rotating the lifting screw to accommodate sheet metal of different thicknesses. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This embodiment provides a positioning device for cutting sheet metal for a perimeter box, such as... Figure 1-4 As shown, the positioning device includes a support 1, a circular saw 2 for cutting plates is provided on one side of the support 1, and a workbench 3 for mounting the circular saw 2 is provided at the bottom of the support 1.

[0023] To facilitate pressing the side of the board away from the backing 1: an adjustment component 4 for adjusting the position of the backing 1 is provided on one side of the backing 1, a push plate 7 for laterally pushing the board is provided on the side of the circular saw 2 away from the backing 1, and a drive component 8 for pushing the push plate 7 is provided on the side of the push plate 7 away from the circular saw 2; the drive component 8 includes a push spring 81 symmetrically arranged on the side of the push plate 7 away from the circular saw 2 for pushing the push plate 7, a guide rod 82 inserted inside the push spring 81 for guiding the movement of the push plate 7, a limiting plate 83 arranged at the end of the guide rod 82 away from the push plate 7 for limiting the movement of the guide rod 82, and a lifting rod 84 arranged on the side of the push plate 7 away from the circular saw 2 for inserting and connecting the guide rod 82. Before cutting the board, adjust the distance between the support plate 1 and the circular saw 2 according to the required cutting size. Then, align one side of the board with the side of the support plate 1 that is closer to the circular saw 2. Next, pull the push plate 7 to move it away from the circular saw 2, placing the side of the board away from the support plate 1 on the push plate 7. Then, release the push plate 7, and under the restoring force of the push spring 81, push the push plate 7 closer to the board, thereby squeezing the board and making it fit against the support plate 1. When cutting the board, the worker only needs to push the part of the board located between the circular saw 2 and the support plate 1, thus avoiding hand injuries from the circular saw 2.

[0024] Specifically, to facilitate the pushing of the push plate 7: the two ends of the guide rod 82 are fixedly connected to the push plate 7 and the opposite side of the limiting plate 83, respectively. The push spring 81 is sleeved on the outer wall of the end of the guide rod 82 away from the limiting plate 83. A through hole for slidingly inserting the guide rod 82 is symmetrically opened on one side of the lifting rod 84. The push spring 81 is set between the push plate 7 and the lifting rod 84. Through the push spring 81 set between the push plate 7 and the lifting rod 84, under the action of the restoring force of the push spring 81, the push plate 7 is pushed to move the plate closer to the backing 1, so that the plate fits against the backing 1 when the plate is cut, without the need for manual support, thus avoiding hand injury. Two guide rods 82 are provided, which are welded and fixed to the two ends of the push plate 7 away from the circular saw 2, respectively. The limiting plate 83 is welded and fixed to the end of the guide rod 82 away from the push plate 7. The size of the limiting plate 83 is 1.2 times the size of the through hole. The size of the through hole on the outer wall of the end of the push spring 81 is adapted to the size of the guide rod 82.

[0025] More specifically, to facilitate the snap-fit ​​of the sheet metal: the vertical cross-section of the push plate 7 is inverted L-shaped. The inverted L-shaped design of the push plate 7 allows it to snap-fit ​​with the edges and corners of the sheet metal, facilitating the pushing of the sheet metal.

[0026] Specifically, to facilitate the adjustment of the height of the push plate 7: the bottom end of the lifting rod 84 is provided with a movable part 9 for adjusting the height of the push plate 7. The movable part 9 includes a lifting screw 91 for adjusting the height of the lifting rod 84. The top end of the lifting rod 84 has a threaded hole, and the lifting screw 91 is threadedly connected to the threaded hole. A second bearing 92 is sleeved on the outer wall of the bottom of the lifting screw 91. A fixing plate 93 for installing the second bearing 92 is fixedly connected to the top end of the worktable 3. The top end of the fixing plate 93 has a groove for the second bearing 92 to fit. By rotating the lifting screw 91, the height of the lifting rod 84 is adjusted, thereby driving the guide rod 82 through the lifting rod 84. The guide rod 82 causes the height of the push plate 7 to change, thus adapting to plates of different thicknesses. The threaded hole is located in the middle of the top of the lifting rod 84. The thread on the inner wall of the threaded hole meshes with the thread on the outer wall of the lifting screw 91. The second bearing 92 installed in the groove restricts the lifting screw 91 to rotate only and prevents it from moving vertically. The bottom end of the fixing plate 93 is welded and fixed to the top of the worktable 3.

[0027] More specifically, to prevent the lifting rod 84 from rotating: a limiting hole is provided on one side of the top of the lifting rod 84, and a second limiting rod 94 for limiting the rotation of the lifting rod 84 is inserted through the limiting hole. The bottom end of the second limiting rod 94 is fixedly connected to one side of the top of the fixing plate 93. By inserting the second limiting rod 94 inside the limiting hole, the rotation of the lifting rod 84 is restricted, and it can only move vertically. The size of the limiting hole is adapted to the size of the second limiting rod 94, and the part of the second limiting rod 94 that contacts the fixing plate 93 is welded and fixed.

[0028] Specifically, to adjust the position of the support 1: the adjustment assembly 4 includes an adjusting screw 41 for moving the support 1, a first bearing 42 sleeved on the outer wall of the end of the adjusting screw 41 to maintain the rotation of the adjusting screw 41, and a first limiting rod 43 symmetrically arranged on the side of the support 1 away from the circular saw 2 to restrict the rotation of the support 1. By rotating the adjusting screw 41, the lateral position of the support 1 can be adjusted, thereby cutting plates of different sizes. The first bearing 42 is sleeved on the outer wall of the adjusting screw 41 near the end of the support 1. The first bearing 42 is installed inside the circular groove, thereby restricting the adjusting screw 41 to only rotate relative to the support 1. The first limiting rod 43 is welded and fixed to the side of the support 1 near the adjusting screw 41.

[0029] More specifically, for the installation of the adjusting screw 41 and the first limiting rod 43: a first mounting plate 5 and a second mounting plate 6 are fixedly connected to the top of the workbench 3 to support the adjusting screw 41 and the first limiting rod 43. One side of the first mounting plate 5 has a threaded groove for threaded insertion of the adjusting screw 41, and one side of the second mounting plate 6 has a through groove for sliding insertion of the first limiting rod 43. A circular groove for installing the first bearing 42 is formed on the side of the support 1 away from the circular saw 2. The adjusting screw 41 is threaded through the first mounting plate 5, and the first limiting rod 43 is slidably inserted into the second mounting plate 6, thereby maintaining the horizontal movement of the support 1. The threads on the inner wall of the threaded groove mesh with the threads on the outer wall of the adjusting screw 41. The size of the circular groove matches the size of the first limiting rod 43. Both the first mounting plate 5 and the second mounting plate 6 are welded and fixed to the parts that contact the top of the support 1.

[0030] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
