Description

Technical Field

[0001] The invention relates to the field of large plate shearing, and in particular to a large plate shearing push plate guide anti-collision device. Background Art

[0002] Large plate nesting refers to placing a whole raw material large plate on the platform surface processing center, so that the whole table surface is adsorbed, and the processing center can automatically change the set tool to complete the cutting and shaping of the whole large plate. We call this process - large plate nesting. During the processing, when the plate to be processed is pushed from the lifting platform position to the engraving direction, due to plate deviation, the plate is not placed neatly, etc., the plate and the conveyor line collide during the pushing process, causing the push plate to fail, and even causing an operation accident.

[0003] However, traditional anti-collision devices have poor adaptability to panels of different sizes, shapes and materials, resulting in ineffective anti-collision in some cases. In addition, traditional anti-collision devices may lack intelligent functions, such as automatically adjusting the pushing speed and automatically correcting the position of panels, resulting in low operating efficiency and prone to errors.

[0004] Moreover, the traditional anti-collision device has no guiding function and can only buffer and correct the deviated panels. In this process, since the conveyor line still maintains a carrying state, when the traditional anti-collision device corrects the panel, the panel will shake due to the external force, which will cause a collision between the panel and the anti-collision device. Summary of the invention

In addition, since the spiral groove has a spiral structure, this structure can generate a certain guiding force when the conical guide wheel rotates, which helps to guide the plate to move in a predetermined direction. When the plate tries to deviate from the predetermined path, the spiral structure of the spiral groove will exert a force opposite to its deviation direction, thereby pulling it back to the correct position.

[0021] Third: This device realizes variable speed positioning of the plate through the positioning disk and the movable disk, ensuring that the plate can achieve full collision prevention and positioning when it is introduced into the machine tool for processing, so that the plate will be limited in direction by the stationary conical guide wheel when it first enters the machine tool. During the movement of the plate, the rotating conical guide wheel will correct and position the plate to ensure that the plate will not collide with the conveyor line due to shaking.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] refer to Figures 1 to 8 A large plate sleeve cutting and pushing plate guide anti-collision device includes a machine tool 1 that can drive a plate 2 to move and cut, and also includes:

[0034] Two clamping mechanisms 35 are symmetrically arranged on both sides of the machine tool 1. Each clamping mechanism 35 includes a movable clamping plate 36. The movable clamping plate 36 is slidably arranged on the upper end of the machine tool 1 (such as Figure 3 and Figure 4 shown);

[0035] The guide mechanism 3 is connected to the movable splint 36, and includes a plurality of positioning boxes 7, a plurality of extrusion curved plates 9 and a plurality of conical guide wheels 4. The plurality of positioning boxes 7 are slidably arranged at equal intervals along the long side direction of the movable splint 36. The plurality of extrusion curved plates 9 are respectively slidably connected to the sides of the plurality of positioning boxes 7 close to the center line of the machine tool 1. The plurality of conical guide wheels 4 are respectively connected to the ends of the plurality of extrusion curved plates 9 away from the plurality of positioning boxes 7. The outer fixed sleeve of each conical guide wheel 4 is provided with a rubber sleeve 5, and a vortex spiral groove 6 (such as Figure 7 shown);

[0036] The locking mechanisms 22 are respectively connected to the positioning boxes 7 and include a reset spring 29 that can drive two adjacent positioning boxes 7 to move closer together.

[0037] When the device is in operation, when the plate 2 moves on the machine tool 1, under the action of the clamping mechanism 35, the clamping mechanism 35 will drive the movable clamping plate 36 to move, so that the guide mechanism 3 connected to the movable clamping plate 36 can contact the plate 2. At this time, the end of the plate 2 that first contacts the machine tool 1 will abut against the multiple conical guide wheels 4 on both sides of the upper end of the machine tool 1. At this time, the multiple conical guide wheels 4 will not rotate. The plate 2 will drive the multiple positioning boxes 7 to move in sequence along the long side direction of the extruded curved plate 9 as the machine tool 1 starts. In this process, every time When the positioning box 7 moves to the extreme position, the reset tension spring 29 used to connect the two positioning boxes 7 will be stretched to the maximum, and then under the action of the locking mechanism 22, the conical guide wheel 4 on the positioning box 7 that has moved to the extreme position will rotate. At this time, when the machine tool 1 drives the plate 2 to move, the conical guide wheel 4 will rotate with the movement of the plate 2, and the vortex spiral groove 6 formed on the rubber sleeve 5 increases the contact area between the rubber sleeve 5 and the plate 2, forming more friction points, which can effectively fix the plate 2 and prevent it from tilting or shifting. And because the vortex spiral groove 6 has a spiral structure, this structure can generate a certain guiding force when the conical guide wheel 4 rotates, which helps to guide the plate 2 to move in a predetermined direction. When the plate 2 attempts to deviate from the predetermined path, the spiral structure of the vortex spiral groove 6 will exert a force opposite to its deviation direction, thereby pulling it back to the correct position.

[0038] In order to supplement the specific structure of the clamping mechanism 35, the following features are also specifically provided:

[0039] The clamping mechanism 35 further includes a positioning push plate 38, a bearing clamp plate 37, a plurality of positioning slide bars 39 and a plurality of movable cylinders 40. The bearing clamp plate 37 is fixedly connected to the side end of the machine tool 1. The plurality of movable cylinders 40 are arranged at equal intervals on the upper end of the bearing clamp plate 37. The positioning push plate 38 is slidably connected to the upper end of the bearing clamp plate 37 and is fixedly connected to the output ends of the plurality of movable cylinders 40 in sequence. The plurality of positioning slide bars 39 are arranged at equal intervals along the side end of the machine tool 1. One end of the plurality of positioning slide bars 39 is respectively fixedly connected to the positioning push plate 38, and the other end is respectively fixedly connected to the movable clamp plate 36. When the movable clamp plate 36 needs to be driven to move, the plurality of movable cylinders 40 can be started to drive the plurality of positioning slide bars 39 to move through the positioning push plate 38. After the plurality of positioning slide bars 39 move, they will drive the movable clamp plate 36 to move. After the movable clamp plate 36 moves, the conical guide wheel 4 can drive the rubber sleeve 5 to press against the plate 2.

[0040] In order to supplement the specific structure of the guide mechanism 3, the following features are also specifically provided:

[0041] The guide mechanism 3 also includes an assembly roller shaft 20, an assembly motor 21, a plurality of bevel gear racks 16, a plurality of active bevel gears 18 and a plurality of driven bevel gears 19. The two ends of the assembly roller shaft 20 are rotatably connected to the movable splint 36 through shaft seats, the assembly motor 21 is fixedly connected to one end of the movable splint 36 through a motor rack, the output end of the assembly motor 21 is coaxially fixedly connected to the assembly roller shaft 20, the plurality of bevel gear racks 16 are respectively fixedly connected to the side of the plurality of positioning boxes 7 away from the extrusion curved plate 9, the plurality of active bevel gears 18 are respectively rotatably connected to the plurality of bevel gear racks 16, the plurality of active bevel gears 18 are respectively key-connected to the assembly roller shaft 20, and the plurality of driven bevel gears 19 are respectively rotatably connected to the plurality of bevel gear racks 16 and meshed with the corresponding active bevel gears 18. After the assembly motor 21 is started, the assembly motor 21 will drive the plurality of active bevel gears 18 to rotate through the assembly roller shaft 20, and the plurality of active bevel gears 18 will respectively drive the plurality of driven bevel gears 19 to rotate. During this process, since the active bevel gears 18 and the assembly roller shaft 20 are key-connected, when the plate 2 pushes the unlocked and non-rotatable conical guide wheel 4 to move, the corresponding active bevel gears 18 will move along the axial direction of the assembly roller shaft 20, and the assembly roller shaft 20 can also maintain transmission with the active bevel gears 18.

[0042] In order to realize that the extruded curved plate 9 drives the conical guide wheel 4 to move, so that the conical guide wheel 4 drives the rubber sleeve 5 to elastically press against the upper end of the plate 2, the following features are also specifically provided:

[0043] The guide mechanism 3 also includes a plurality of extrusion tension springs 10, a plurality of extrusion support plates 11 and a plurality of positioning shafts 12. The plurality of extrusion support plates 11 are respectively arranged above the plurality of positioning boxes 7. The plurality of positioning shafts 12 are respectively fixedly connected to the four corners of the lower ends of the plurality of extrusion support plates 11. The lower ends of the plurality of positioning shafts 12 are respectively slidably connected to the plurality of positioning boxes 7. The upper ends of the plurality of extrusion tension springs 10 are respectively fixedly connected to the plurality of extrusion curved plates 9, and the lower ends are respectively fixedly connected to the plurality of extrusion support plates 11. When the rubber sleeve 5 outside the plate 2 and the conical guide wheel 4 are against each other, under the action of the plurality of extrusion tension springs 10, the plurality of extrusion tension springs 10 will pull the plurality of extrusion support plates 11 to move downward, and the extrusion support plates 11 can drive the conical guide wheel 4 to move downward (the specific movement process will be explained later) until the rubber sleeve 5 elastically presses against the upper end of the plate 2.

[0044] In order to change the tension of the extrusion tension spring 10 and ensure that the conical guide wheel 4 can generate a greater friction force through the rubber sleeve 5 and the plate 2, the following features are also specifically provided:

[0045] The guide mechanism 3 further includes a plurality of adapter support plates 13, a plurality of adjusting screw sleeves 14, a plurality of adjusting screw rods 15 and a plurality of adjusting rod sleeves 17. The plurality of adapter support plates 13 are respectively fixedly connected to the plurality of extrusion support plates 11, the plurality of adjusting screw sleeves 14 are respectively fixedly connected to the middle parts of the plurality of adapter support plates 13, the plurality of adjusting rod sleeves 17 are respectively fixedly connected to the coaxial lines of the plurality of driven bevel gears 19, the plurality of adjusting rod sleeves 17 are respectively fixedly connected to the lower ends of the plurality of adjusting screw rods 15, and the plurality of adjusting screw rods 15 are respectively threadedly connected to the plurality of adjusting screw sleeves 14. When it is necessary to drive the extrusion support plate 11 to move, the rotation of the driven bevel gear 19 will drive the adjusting screw rod 15 to rotate through the adjusting rod sleeve 17, and the rotation of the adjusting screw rod 15 will drive the adapter support plate 13 to move through the adjusting screw sleeve 14, and the adapter support plate 13 will drive the extrusion tension spring 10 to deform through the extrusion support plate 11, thereby realizing the change of the tension of the extrusion tension spring 10.

[0046] In order to supplement the specific structure of the locking mechanism 22, the following features are also specifically provided:

[0047] A limited position perforation 8 (such as Figure 2 and Figure 8 As shown), the locking mechanism 22 also includes a locking pin shaft 24, a movable disk 25, a positioning disk 26, a sliding lock seat 27 and two sliding carriers 23. The locking pin shaft 24 is rotatably connected to the extrusion curved plate 9, one end of the locking pin shaft 24 is coaxially fixedly connected to the conical guide wheel 4, and the two sliding carriers 23 are symmetrically slidably arranged inside the positioning box 7. The other end of the locking pin shaft 24 passes through the limiting perforation 8 and is rotatably connected to the two sliding carriers 23 respectively. The movable disk 25 is rotatably connected to the sliding carrier 23 close to the limiting perforation 8, the movable disk 25 is coaxially fixedly connected to the locking pin shaft 24, the positioning disk 26 is arranged on the side of the movable disk 25 away from the limiting perforation 8 and can be connected to the movable disk 25 through magnetic force, the positioning disk 26 is slidably connected to the locking pin shaft 24, and the upper end of the sliding lock seat 27 is fixedly sleeved with the positioning disk 26. When the conical guide wheel 4 contacts the plate 2 through the rubber sleeve 5, since the movable magnetic disk 25 and the positioning magnetic disk 26 are attracted to each other by magnetic force and the positioning magnetic disk 26 does not rotate, the movement of the corresponding plate 2 at this time will not drive the rotation of the conical guide wheel 4. As the plate 2 moves, the plate 2 will push the positioning box 7 to move through the conical guide wheel 4 until it moves to the limit distance. At this time, as the plate 2 continues to move, the sliding lock seat 27 will drive the positioning magnetic disk 26 and the movable magnetic disk 25 to separate (the specific separation process will be explained later), and the corresponding conical guide wheel 4 will rotate. During the rotation of the conical guide wheel 4, the moving plate 2 can be limited to prevent the plate 2 from moving.

[0048] In order to achieve the phase separation of the positioning disk 26 and the movable disk 25, the following features are also specifically set:

[0049] The locking mechanism 22 also includes a disengagement screw 33, a disengagement screw sleeve 34, two pulling racks 28, two pulling gears 31 and two sliding limit pins 32. The disengagement screw sleeve 34 is fixedly connected to the lower end of the sliding lock seat 27. The two sliding limit pins 32 are symmetrically arranged on both sides of the sliding lock seat 27 and are respectively slidably connected to the sliding lock seat 27. The two ends of the sliding limit pin 32 are respectively fixedly connected to the two sliding carriers 23. The disengagement screw 33 is threadedly connected to the disengagement screw sleeve 34. The two pulling gears 31 are respectively rotatably connected to the lower parts of the two sliding carriers 23 through torsion springs. The two pulling gears 31 are respectively coaxially fixedly connected to the two ends of the disengagement screw 33. The two pulling racks 28 are respectively slidably connected to the lower ends of the two sliding carriers 23 (such as Figure 6 and Figure 8 As shown in the figure, the two pulling racks 28 are respectively meshed with the two pulling gears 31. During the sliding process of the plurality of positioning boxes 7 (i.e., the relative distance between two adjacent positioning boxes 7 increases), the corresponding pulling racks 28 will move (the specific movement process will be explained later). After the pulling racks 28 move, they will drive the disengagement screw 33 to rotate through the pulling gear 31. When the disengagement screw 33 rotates, it will drive the sliding lock seat 27 to move through the disengagement screw sleeve 34. During the movement of the sliding lock seat 27, the positioning disk 26 and the movable disk 25 will be separated.

[0050] In order to facilitate the movement and limiting of the positioning boxes 7 and the subsequent resetting, the following features are also specifically provided:

[0051] The locking mechanism 22 also includes a telescopic tube 30, which is coaxially arranged with the reset spring 29. The two ends of the telescopic tube 30 are respectively fixedly connected to the two ends of the reset spring 29. One end of the telescopic tube 30 is fixedly connected to the adjacent positioning box 7, and the other end is fixedly connected to the two connected pulling racks 28. During the movement of the positioning box 7, the telescopic tube 30 will be extended and retracted, and at the same time drive the corresponding reset spring 29 to deform, so as to provide power for the subsequent resetting of the positioning box 7. In this process, since the telescopic tube 30 will not change after being stretched to the extreme position, the positioning box 7 continues to move at this time, so that the telescopic tube 30 drives the two pulling racks 28 to move, thereby realizing the driving of the pulling racks 28.

[0052] The working principle of this device is that when the device is in operation, when the plate 2 moves on the machine tool 1, under the action of several active cylinders 40, the active splint 36 will drive several conical guide wheels 4 to approach the plate 2 until the fleshy rubber sleeve 5 and the plate 2 are in contact. At this time, the several conical guide wheels 4 will not rotate, and the plate 2 will drive several positioning boxes 7 to move in sequence along the long side direction of the extrusion curved plate 9 as the machine tool 1 starts. In this process, whenever the positioning box 7 moves to the extreme position, the reset tension spring 29 used to connect the two positioning boxes 7 will be stretched to the maximum, and then under the action of the pulling rack 28, the active disk 25 and the positioning disk 26 will be separated, that is, the conical guide wheel 4 on the corresponding positioning box 7 that has moved to the extreme position will rotate. At this time, when the machine tool 1 drives the plate 2 to move, the conical guide wheel 4 will rotate with the movement of the plate 2, and the vortex spiral groove 6 formed on the rubber sleeve 5 increases the contact area between the rubber sleeve 5 and the plate 2, forming more friction points, which can effectively fix the plate 2 and prevent it from tilting or shifting. And because the vortex spiral groove 6 has a spiral structure, this structure can generate a certain guiding force when the conical guide wheel 4 rotates, which helps to guide the plate 2 to move in a predetermined direction. When the plate 2 tries to deviate from the predetermined path, the spiral structure of the vortex spiral groove 6 will exert a force opposite to its deviation direction, thereby pulling it back to the correct position.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
