[0048] As known from the background art, it is usually necessary to cut the board in accordance with the design requirements to ensure that it has accurate size and shape. The board can be a flat material made of wood, artificial board, metal or other materials.

[0049] During the existing sheet metal cutting process, the sheet metal may not be properly positioned after loading, requiring the operator to lift the sheet metal to the preset position on the workbench so that it abuts the cutting block and determines the cutting position. However, when the sheet metal is thick or heavy, manual adjustment of the sheet metal position by the operator is labor-intensive and time-consuming, making the operation difficult and affecting efficiency. Furthermore, the sheet metal may fall due to the inconvenience of lifting, posing a safety hazard.

[0050] In response to the above-mentioned problems existing in the prior art, the present application provides a plate positioning device and a blanking machine. The plate positioning device includes an operating table, at least two clamping assemblies and at least one second driving member; the clamping assemblies are relatively arranged on the operating table, and the clamping assemblies include a first driving member and a clamping member, and the clamping member includes two relatively arranged clamping blocks, and the clamping blocks are connected to the first driving member; the second driving member is arranged on the operating table. By setting the clamping assemblies, under the driving action of the second driving member, the two relatively clamping assemblies can push and clamp the plate along the second direction; each clamping assembly has two clamping blocks, which can push and clamp the plate along the first direction of the operating table under the driving action of the first driving member. The first direction and the second direction are perpendicular, and the plate can be moved and clamped and positioned. The plate positioning device of the present application does not need to rely on the operator to manually move the plate. The plate can be moved by operating the first driving member and the second driving member, which solves the problems of difficult and low operating efficiency of manually moving the plate, and also helps to improve the safety during the plate movement process.

[0051] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0052] Reference below Figures 1 to 5 The plate positioning device and blanking machine provided in the embodiments of the present application are described in detail.

[0053] Figure 1 A schematic structural diagram of a plate positioning device provided in an embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the structure of the clamping assembly; Figure 3 for Figure 1 Schematic diagram of the structure of the clamping component in another posture.

[0054] On the one hand, combined with Figures 1 to 3 As shown, the present application provides a plate positioning device, including an operating table 100, at least two clamping assemblies 200 and at least one second driving member 300; the clamping assembly 200 is relatively arranged on the operating table 100, the clamping assembly 200 includes a first driving member 210 and a clamping member 220, the clamping member 220 includes two relatively arranged clamping blocks 221, the clamping blocks 221 are connected to the first driving member 210, the first driving member 210 is used to drive the two clamping blocks 221 to move closer to or away from each other along the first direction of the operating table 100, so as to abut or disengage with the plate 1; the second driving member 300 is arranged on the operating table 100, the second driving member 300 is used to drive the clamping assembly 200 corresponding thereto to move along the second direction of the operating table 100 to abut or disengage with the plate 1; the first direction and the second direction are perpendicular.

[0055] Exemplarily, the first direction is the width direction of the operating table 100 , and the second direction is the length direction of the operating table 100 .

[0056] The number of clamping assemblies 200 is preferably two, and they are arranged relative to each other in the longitudinal direction of the operating table 100. The two clamping blocks 221 in each clamping assembly 200 are distributed in the width direction of the operating table 100. The two clamping blocks 221 are driven by the first driving member 210 to move relative to each other, pushing and clamping the plate 1 along the width direction of the operating table 100, so that the plate 1 moves to a predetermined position in the width direction of the operating table 100. The clamping assembly 200 is driven by the second driving member 300 connected thereto, and can move as a whole along the longitudinal direction of the operating table 100 to push and clamp the plate 1 along the longitudinal direction of the operating table 100, so that the plate 1 moves to a predetermined position in the longitudinal direction of the operating table 100.

[0057] When there is only one second driving member 300, it is connected to one of the two clamping assemblies 200, and the other clamping assembly 200 is fixedly mounted on the operating table 100. By adjusting the second driving member 300, the second driving member 300 can drive the clamping assembly 200 connected thereto to move closer to the other clamping assembly 200, thereby pushing the misplaced sheet 1 to move and clamping the sheet 1 after it is moved into place.

[0058] When there are two second driving members 300, each connected to a corresponding clamping assembly 200, both clamping assemblies 200 can be moved under the drive of the second driving member 300. By adjusting the second driving member 300, when the two clamping assemblies 200 move toward each other, they can push the misplaced sheet 1 to move and clamp the sheet 1 after it is moved into place; when the two clamping assemblies 200 move away from each other, they can break away from the abutment with the sheet 1; when the two clamping assemblies 200 move in the same direction, the position of the sheet 1 relative to the cutting device can be adjusted to facilitate adjustment of the sheet 1 to a predetermined position.

[0059] Specifically, the plate positioning device provided in the present application does not require an operator to manually move the plate 1. The plate 1 can be moved by operating the first driving member 210 and the second driving member 300, thereby solving the problem of difficulty and low efficiency in manually moving the plate 1, and also helping to improve the safety of the plate 1 during movement.

[0060] In some embodiments, the clamping assembly 200 also includes a shell 230, and a first opening 231 and a second opening 232 are respectively opened on a pair of sides of the shell 230; the first driving member 210 includes a first threaded rod 211, and the first threaded rod 211 is inserted into the shell 230 through the first opening 231; the clamping block 221 is inserted into the shell 230 through the second opening 232, and the first threaded rod 211 located in the shell 230 drives the clamping block 221 to move.

[0061] The first opening 231 and the second opening 232 are located on a pair of sides of the housing 230 along the length of the operating table 100. The first opening 231 is located on the side of the housing 230 facing away from the operating table 100, and the second opening 232 is located on the side of the housing 230 facing the operating table 100.

[0062] Before loading the plate 1, first adjust the distance between the two clamping blocks 221 in the clamping assembly 200 by the first threaded rod 211 so that it is larger than the width of the plate 1 (i.e. the length of the plate 1 along the width direction of the operating table 100), and adjust the distance between the two clamping assemblies 200 by the second driving member 300 so that it is larger than the length of the plate 1 (i.e. the length of the plate 1 along the length direction of the operating table 100). After loading the plate 1, it is placed on the operating table 100 and located between the two clamping assemblies 200. At this time, the position of the plate 1 may deviate from the preset position. The operator can first operate the second driving member 300 to The distance between the two clamping assemblies 200 is reduced to drive the plate 1 to move and abut against the plate 1 in the length direction of the plate 1; then the end of the first threaded rod 211 located outside the shell 230 is operated to make the first driving member 210 run to drive the two clamping blocks 221 outside the second opening 232 to move relative to each other, and the distance between the two clamping blocks 221 is reduced to drive the plate 1 to move and abut against the plate 1 in the width direction of the plate 1; finally, by adjusting the second driving member 300 to make the two clamping assemblies 200 move in the same direction, the position of the plate 1 on the operating table 100 can be adjusted to adjust the plate 1 to a preset position.

[0063] In some embodiments, a sleeve 233 is connected to the first opening 231 , and the first threaded rod 211 is connected to the sleeve 233 through threaded engagement.

[0064] Among them, the sleeve 233 is fixedly installed in the first opening 231, and an internal thread is provided on the inner wall of the sleeve 233, and an external thread is provided on the side wall of the first threaded rod 211. Through the matching connection of the internal thread and the external thread, when the first threaded rod 211 is rotated, the length of the first threaded rod 211 inserted into the shell 230 can be adjusted, thereby realizing the operation of the first driving member 210.

[0065] By arranging the sleeve 233 in the first opening 231, compared with the method in which the first threaded rod 211 is directly connected to the side wall of the shell 230 through threaded fitting, the length of the threaded fitting portion between the two is increased, which can ensure the effectiveness of the threaded connection and avoid the first threaded rod 211 from tilting or shifting during rotation, thereby affecting the operation of the first driving member 210, so as to ensure the clamping effect of the clamping block 221 on the plate 1.

[0066] In some embodiments, the first driving member 210 also includes: a driving block 212 arranged in the shell 230, the driving block 212 is connected to the end of the first threaded rod 211; two first connecting rods 213 arranged opposite to each other are correspondingly hinged at both ends of the driving block 212; two second connecting rods 214 arranged opposite to each other are correspondingly hinged to the end of the first connecting rod 213 away from the driving block 212, and the end of the second connecting rod 214 away from the first connecting rod 213 is hinged to the shell 230; two rotating wheels 215 arranged opposite to each other are rotatably connected to the shell 230, the rotating wheel 215 is correspondingly connected to the end of the second connecting rod 214 away from the first connecting rod 213, and the rotating wheel 215 is correspondingly connected to the clamping block 221; the first threaded rod 211 drives the rotating wheel 215 to rotate through the driving block 212, the first connecting rod 213 and the second connecting rod 214, so that the rotating wheel 215 drives the corresponding clamping block 221 to move close to or away from the other clamping block 221.

[0067] When implementing it specifically, Figure 3 As shown, when the first threaded rod 211 moves toward the direction close to the second opening 232 through the threaded cooperation with the sleeve 233, the end of the first threaded rod 211 located inside the shell 230 will drive the driving block 212 to move close to the second opening 232, and the driving block 212 will drive the end of the first connecting rod 213 hinged thereto to move, and the other end of the first connecting rod 213 will swing toward the direction close to the first threaded rod 211, and will drive the end of the second connecting rod 214 hinged thereto to move toward the direction close to the first threaded rod 211. Since the other end of the second connecting rod 214 is hinged to the bottom wall of the shell 230, its position in the shell 230 remains unchanged, but it will rotate relative to the shell 230, thereby driving the rotating wheel 215 connected thereto to rotate around the hinge axis. The two rotating wheels 215 respectively move along Figure 2 The clamping blocks 221 rotate in the direction of the arrow A to drive the two clamping blocks 221 away from each other.

[0068] Combine Figure 2 As shown, when the first threaded rod 211 moves in the direction away from the second opening 232, the end of the first threaded rod 211 located inside the shell 230 will drive the driving block 212 away from the second opening 232, and the driving block 212 will drive the end of the first connecting rod 213 hinged thereto to move, and the other end of the first connecting rod 213 will swing in the direction away from the first threaded rod 211, and will drive the end of the second connecting rod 214 hinged thereto to move in the direction away from the first threaded rod 211. The other end of the second connecting rod 214 is hinged to the bottom wall of the shell 230, and its position in the shell 230 remains unchanged, but it will rotate relative to the shell 230, thereby driving the rotating wheel 215 connected thereto to rotate around the hinge axis. The rotation directions of the two rotating wheels 215 are respectively Figure 2 The direction of the arrow A is opposite to that of the other, so as to drive the two clamping blocks 221 closer to each other.

[0069] Through the above-mentioned structure, under the drive of the first threaded rod 211, the two relatively arranged rotating wheels 215 can rotate synchronously, realizing the synchronous driving of the two clamping blocks 221, clamping the plate 1 from the width direction of the plate 1, which helps to automatically align the plate 1, saves operation steps, and improves operation efficiency; in addition, the clamping distance of the two clamping blocks 221 is adjustable, which can adapt to plates 1 of different widths and has strong flexibility.

[0070] In some embodiments, the clamping block 221 is provided with an engaging portion 2211 , which is located in the housing 230 , and the rotating wheel 215 is provided with a tooth portion 2151 matching the engaging portion 2211 , and the engaging portion 2211 meshes with the tooth portion 2151 .

[0071] Among them, the second opening 232 extends along the width direction of the operating table 100, the extension direction of the engaging portion 2211 is consistent with the extension direction of the second opening 232, and the engaging portion 2211 is arranged on the position where the clamping block 221 is located in the shell 230, and is located on the side of the clamping block 221 away from the second opening 232 so as to engage with the rotating wheel 215.

[0072] Furthermore, the engaging portion 2211 may also be provided on the top wall or the bottom wall of the clamping block 221 , as long as it can be engaged with the rotating wheel 215 , and this application does not impose any limitation on this.

[0073] In an embodiment of the present application, in order to ensure that the clamping block 221 remains parallel to the surface of the operating table 100 during movement, for example, a support block can also be provided at the bottom of the clamping block 221 located in the shell 230. The bottom of the support block is slidably connected to the bottom surface of the shell 230, and the top of the support block is fixedly connected to the mounting portion. In this way, the support block can provide support for the clamping block 221 to prevent the clamping block 221 from tilting during movement, thereby ensuring the clamping effect.

[0074] Exemplarily, the rotating wheel 215 can be a gear, and the tooth portion 2151 on the gear can be distributed over the entire circumference of the gear or part of the circumference of the gear. As long as the rotating wheel 215 can engage with the meshing portion 2211 within its rotation angle to drive the clamping block 221 to move to achieve driving and abutment of the plate 1, this application does not impose any restrictions on this.

[0075] In some embodiments, the opposing surfaces of the two clamping blocks 221 are each provided with a clamping groove 2212 , and the clamping groove 2212 is used to accommodate the side edge of the plate 1 .

[0076] The end of the clamping groove 2212 facing away from the housing 230 is in communication with the outside world, so that the plate 1 can be inserted into the clamping groove 2212. By providing the clamping groove 2212 on the clamping portion, the plate 1 can be inserted into the clamping groove 2212 and kept parallel to the table surface of the operating table 100, thereby preventing the plate 1 from tilting and ensuring cutting accuracy.

[0077] In some embodiments, a slide groove 110 is provided on the operating table 100, and the extension direction of the slide groove 110 is consistent with the second direction. A protrusion 234 is provided on the side of the shell 230 facing the operating table 100, and the protrusion 234 is embedded in the slide groove 110, and the second driving member 300 is connected to the protrusion 234.

[0078] The chute 110 is formed on the top wall of the operating table 100. The chute 110 has two sections, distributed along the length of the operating table 100. The two sections of the chute 110 correspond one-to-one to the two clamping assemblies 200. The housing 230 is slidably connected to the chute 110 via a protrusion 234. In other embodiments, the chute 110 may be provided with only one section, so that the protrusion 234 can slide within the chute 110 to drive the clamping assembly 200 to move along the chute 110. This application is not limited to this.

[0079] Furthermore, a plurality of legs 120 are provided around the bottom wall of the operating platform 100. The legs 120 can raise the operating platform 100 to a certain height to accommodate the height of the operator, thereby preventing the operator from excessively bending over during operation. The legs 120 can be configured to be retractable so as to be adjustable for operators of different heights.

[0080] Specifically, two opposing support portions 130 are provided on the top wall of the operating table 100 . The support portions 130 are correspondingly supported below the clamping member 220 . The gap between the two support portions 130 forms an avoidance groove 140 to avoid the tool of the cutting equipment.

[0081] In some embodiments, the second driving member 300 is a second threaded rod, one end of the second threaded rod is connected to one end face of the slide groove 110, and the other end of the second threaded rod extends to the outside of the operating table 100 through a through hole opened on the other end face of the slide groove 110. The second threaded rod is also connected to the protrusion 234 through a threaded connection to drive the clamping assembly 200 to move along the slide groove 110.

[0082] When the slide groove 110 has two sections, the ends of the two sections of the slide groove 110 close to the operating table 100 are both rotatably connected to the second threaded rod, and can limit the movement of the second threaded rod along the extension direction of the slide groove 110; a through hole is opened at the end of the slide groove 110 away from the operating table 100, and the second threaded rod is inserted into the through hole and rotatably connected to the through hole.

[0083] When the slide groove 110 has only one section, through holes are opened at both ends of the slide groove 110, and the second threaded rod is passed through the through hole and is rotatably connected to the through hole. A limiting convex ring can be provided on the second threaded rod so as to abut against the wall surfaces at both ends of the through hole to limit the movement of the second threaded rod along the extension direction of the slide groove 110.
