[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0038] The embodiment of the present invention provides a plate locking structure of a shearing machine, and the plate locking structure of the shearing machine includes a feeding platform 1, a vertical positioning mechanism 2, a horizontal positioning mechanism 3 and an auxiliary feeding component 4;

[0039] The loading platform 1 is as follows:

[0040] See also Figure 3 The feeding platform 1 is installed on the shearing machine. The upper end surface of the feeding platform 1 is rectangular. The feeding platform 1 is also provided with a through slide 11, a through opening 12 and a through hole 13; the through slide 11 is symmetrically arranged in two groups, and is respectively close to the two sides of the feeding platform 1. The through slide 11 is along the length direction of the feeding platform 1. The through opening 12 is a group and is close to the middle position of the feeding platform 1. The through opening 12 is long and strip-shaped, and the length direction is along the width direction of the feeding platform 1.

[0041] It should be noted that: the loading platform 1 is a workbench in an existing plate shearing machine, and the plate to be processed can be placed on the loading platform 1, and then the plate body is pushed to move for loading.

[0042] The vertical positioning mechanism 2 is as follows:

[0043] See also Figure 4The vertical positioning mechanism 2 also includes two fixed chassis 21, which are bolted to the upper end of the feeding platform 1 and away from the center. A fixed rod 22 is vertically welded to the upper end of the fixed chassis 21, and a sliding mounting tube 23 is sleeved on the fixed rod 22. The outer circumferential wall of the mounting tube 23 is integrally connected with a first mounting frame 24, and the other end of the first mounting frame 24 has a slot 25. One side of the first mounting frame 24 has a pressing plate 29 located directly above the feeding platform 1, and both ends of the pressing plate 29 are integrally connected with an extension plate 210, which is inserted into the slot 25 and fixed to the first mounting frame 24 by bolts;

[0044] A second mounting frame 26 is also sleeved and fixed on the upper end of the fixing rod 22, and a hydraulic cylinder 27 is bolted to the second mounting frame 26. The output end of the hydraulic cylinder 27 is vertically downward and is bolted to a connecting plate 28. The connecting plate 28 is welded and fixed to the mounting tube 23 to drive the mounting tube 23 to move up and down.

[0045] It should be noted that: in the vertical positioning mechanism 2, the pressing plate 29 is the main fixed structure, and the pressing plate 29 can be lifted and moved, and can clamp and fix the plate in cooperation with the feeding platform 1 to ensure the subsequent stable cutting of the plate;

[0046] When in use, the output end of the hydraulic cylinder 27 is fixed to the connecting plate 28, and the connecting plate 28 is welded and fixed to the mounting cylinder 23, so that the mounting cylinder 23 can be driven to move up and down. The first mounting frame 24 on the side of the mounting cylinder 23 is a structure for mounting the pressing plate 29, so as to fix the pressing plate 29, and thus the pressing plate 29 can be driven to move together, so as to adjust the pressing plate 29.

[0047] For the installation of the pressing plate 29, an integrally connected extension plate 210 is provided at its end, and a slot 25 is provided on the first mounting frame 24. The extension plate 210 can be inserted into the slot 25 to achieve a preliminary connection between the two, and then reinforced by bolts;

[0048] The shape of the slot 25 is preferably a U-shaped shape, so after the extension plate 210 is plugged into the first mounting frame 24, the first mounting frame 24 can bear the gravity of the pressure plate 29, reduce the pressure on the bolts, avoid deformation of the bolts due to long-term squeezing, and facilitate subsequent disassembly and maintenance of the pressure plate 29.

[0049] The lateral positioning mechanism 3 is as follows;

[0050] See also Figure 5The lateral positioning mechanism 3 includes two first mounting seats 31, which are bolted to the lower end of the loading platform 1, and the two first mounting seats 31 are rotatably connected with a single screw 32, and a motor driving the single screw 32 to rotate is also installed, and a transmission seat 33 is threadedly connected to the single screw 32, and a mounting plate 34 is welded to the upper end of the transmission seat 33, and two fixed foot blocks 35 are bolted to the upper end of the mounting plate 34, and a gear lever 36 is inserted or threadedly connected to the upper end of the fixed foot block 35;

[0051] The single spiral screw 32 is arranged along the length direction of the through slide 11 , the fixed foot block 35 extends into the through slide 11 and is slidably connected thereto, and the top of the shift rod 36 extends above the through slide 11 .

[0052] It should be noted that: the lateral positioning mechanism 3 is divided into two groups, and the two groups of lateral positioning mechanisms 3 can be operated and used independently. The gear rods 36 in the two groups of lateral positioning mechanisms 3 are located on both sides of the plate to be processed, and any group of lateral positioning mechanisms 3 has two gear rods 36. When the gear rods 36 contact and squeeze the side of the plate, the plate can be clamped and fixed, further improving the stability of the plate, and at the same time, the plate can be straightened to avoid the deflection of the plate, thereby improving the subsequent cutting quality;

[0053] When in use, the motor drives the single screw 32 to rotate, and then drives the transmission seat 33 to move through the single screw 32 to adjust the position of the gear lever 36;

[0054] If the plate to be processed is always a regular rectangular plate, the single spiral screw 32 can be changed to a left-right rotation adjustment screw, so that the two transmission seats 33 can be synchronously driven to move symmetrically, which can reduce the production cost of the device;

[0055] Regarding the installation of the lever 36 , it is preferably a detachable connection. When the lever 36 is used for a long time, it will also be subjected to the reaction force generated by the plate, so it is easy to deform. Therefore, it is designed to be a detachable connection to facilitate the disassembly and replacement of the lever 36 .

[0056] The auxiliary feeding component 4 is as follows:

[0057] See also Figure 6 The auxiliary loading assembly 4 includes a horizontally arranged transverse plate 41 located below the loading platform 1. A vertically arranged connecting rod 42 is welded at a position away from the center at the upper end of the transverse plate 41. The connecting rod 42 is extended along the through hole 13 to the upper part of the loading platform 1 and is fixed to the lower end of the extension plate 210. The transverse plate 41 is driven to move vertically through the pressing plate 29. A support block 43 is bolted to the upper end of the transverse plate 41. A plurality of equidistantly arranged second mounting seats 44 are integrally connected to the upper end of the support block 43. A ball 45 is embedded in the upper end of the second mounting seat 44.

[0058] The support block 43 is located inside the through opening 12 . When the pressing plate 29 moves to the highest position, the upper end of the second mounting seat 44 extends above the loading platform 1 , and the ball bearing 45 contacts the plate to be processed.

[0059] It should be noted that in the auxiliary loading assembly 4, the upper end of the connecting rod 42 is fixed to the extension plate 210, and the lower end is fixed to the cross plate 41. Therefore, when the pressing plate 29 moves up and down, it can drive the cross plate 41 to move together, so as to adjust the position of the entire auxiliary loading assembly 4.

[0060] When the pressing plate 29 releases the clamping fixation on the plate, it moves upward, thereby driving the cross plate 41 to move upward together, and the support block 43 on the cross plate 41 is located inside the through hole 12, and can also move upward along the through hole 12 until the second mounting seat 44 moves to the top of the loading platform 1. At this time, the ball 45 lifts the plate, so when loading, it can be assisted by the ball 45, and pushing the plate will be more labor-saving and convenient;

[0061] When the pressing plate 29 squeezes and fixes the plate, the cross plate 41 will also move downward, causing the support block 43 and the ball bearing 45 and other structures to shrink into the through-hole 12. At this time, the loading platform 1 is in contact with the plate, so when the plate is fixed later, the stability will be higher.

[0062] The specific use process of the device is as follows:

[0063] (1) Alignment and positioning of panels;

[0064] After the plate is completely loaded, the lateral positioning mechanism 3 is first used to perform preliminary straightening and positioning on the plate, that is, the single screw 32 is driven by the motor to rotate, and then the transmission seat 33 is driven to move by the single screw 32, and then the gear rod 36 is driven to move together, so that the gear rod 36 contacts the side end of the plate and squeezes it. Under the action of this pressure, the deflected plate can first be rotated to a straight state to improve the subsequent cutting quality, and at the same time, the plate can be initially clamped and fixed;

[0065] (2) Clamping and fixing of panels;

[0066] After the straightening and positioning of the plate is completed, the plate is clamped and fixed by the vertical positioning mechanism 2, that is, the output end of the hydraulic cylinder 27 is fixed to the connecting plate 28, and the connecting plate 28 is welded and fixed to the mounting cylinder 23, so that the mounting cylinder 23 can be driven to move up and down. The first mounting frame 24 on the side of the mounting cylinder 23 is a structure for mounting the pressing plate 29 to fix the pressing plate 29, so that the pressing plate 29 can also be driven to move together, so as to adjust the pressing plate 29, so that the pressing plate 29 cooperates with the feeding platform 1 to fix the plate;

[0067] (3) Loading of panels;

[0068] After completing one cutting of the plate, the restrictions on the plate by the pressure plate 29 and the gear lever 36 are released. In the process of the pressure plate 29 moving upward, the cross plate 41 will be driven to move upward together. The support block 43 on the cross plate 41 is located inside the through-opening 12 and can also move upward along the through-opening 12 until the second mounting seat 44 moves to the top of the loading platform 1. At this time, the ball 45 lifts the plate. Therefore, when loading, the ball 45 can be used to assist, and pushing the plate will be more labor-saving and convenient.

[0069] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
