[0002] At present, online follow-up cutting saws have been widely used in energy-saving building board production, gypsum board production, wood processing, steel plate production and other industries. Since the cutting saw gives cutting force to the board during the cutting process, and the board gives the cutting saw reverse cutting resistance, the cutting device will vibrate during cutting, resulting in displacement. If the displacement of the cutting device cannot be well aligned with the conveyor line of the upstream conveying board, one is that the board cannot be smoothly moved to the cutting equipment, and the other is that the cutting saw cannot be well aligned with the cutting position of the board, then the cutting position will be offset during cutting, resulting in cutting defects and poor product manufacturing. Summary of the invention

[0033] The cutting equipment used for online following is usually installed on the embedded parts at the installation position, which makes the cutting equipment fixed relative to the installation position. However, when the cutting equipment is cutting the plate, the counter-cutting force given by the plate will cause the cutting equipment to vibrate, which will cause the embedded parts to loosen over time, causing the cutting equipment to move. When the cutting equipment is displaced, usually, because the cutting equipment itself is heavy and cannot be pushed manually, the operator will use a sledgehammer to hit the cutting equipment to give the cutting equipment an impact force to restore the cutting equipment to its original position. This method not only has the risk of damaging the cutting equipment, but also makes it difficult to adjust it in place at one time, and it requires multiple impacts to restore the cutting equipment to its original position, which makes the operation difficult.

[0034] Based on this, the inventor of the present application attempted to provide a calibration device that would not damage the installation point and could adjust the position of the cutting device when it was installed or shifted, thereby facilitating position calibration while ensuring the safety of the cutting device.

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0036] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0038] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] like Figure 1-2 As shown, the embodiment of the present application provides a calibration device 1, which includes a positioning base plate 10, an adjustment plate 20 and an adjustment component 30, wherein the positioning base plate 10 is located at the installation position, the shearing device 2 is arranged on the adjustment plate 20, and the adjustment plate 20 drives the shearing device 2 to be located on the positioning base plate 10 to achieve the rough positioning of the shearing device 2. The positioning base plate 10 will not move relative to the installation position, the adjustment plate 20 can move relative to the positioning base plate 10, and multiple groups of adjustment components 30 can be movably installed on the positioning base plate 10 and abut against the adjustment plate 20. The position of the adjustment component 30 can be adjusted to achieve the position of the adjustment plate 20 on the positioning base plate 10, thereby driving the shearing device 2 to further adjust its position. The adjustment range of the adjustment component 30 is greater than or equal to 0.5 mm and less than or equal to 10 cm, so that the shearing device 2 can be fine-tuned. If the shearing device 2 is displaced after shearing, the position calibration of the shearing device 2 can be achieved by adjusting the adjustment component 30, which is convenient to operate. It is understandable that even if the shearing device 2 vibrates during the process of shearing the plate, the displacement of the shearing device 2 caused by the vibration is relatively small, so fine-tuning is required, and the adjustment range of 0.5mm to 10cm just meets the displacement requirements of the shearing device 2. In addition, due to the presence of the positioning base plate 10, it is not necessary to pre-install embedded parts on the installation position, and the problem of connection failure at the installation point will not occur, and it is convenient to move the shearing device 2 to adapt to the planning and adjustment of the factory.

[0040] In some embodiments of the present application, the projection area of ​​the shearing device 2 on the horizontal plane is smaller than the area of ​​the adjustment plate 20, and the area of ​​the adjustment plate 20 is smaller than the area of ​​the positioning base plate 10, so the adjustment plate 20 can cover the entire shearing device 2, and the friction between the adjustment plate 20 and the positioning base plate 10 is greater than the friction when the shearing device 2 and the positioning base plate 10 are directly in contact, thereby increasing the difficulty of the shearing device 2 to move its position. The larger the area of ​​the positioning base plate 10, the greater the friction between it and the surface to be installed, and the higher the stability of the positioning base plate 10.

[0041] Furthermore, in some embodiments of the present application, the positioning base plate 10 is a steel plate, and the material thickness of the positioning base plate 10 is less than or equal to 20 mm and greater than or equal to 10 mm, so that the positioning base plate 10 is heavier, thereby increasing the friction between the positioning base plate 10 and the surface to be installed, and preventing the positioning base plate 10 from moving relative to the surface to be installed when the shearing device 2 vibrates. It can be understood that since the area of ​​the positioning base plate 10 is much larger than that of the adjustment plate 20, and the weight of the positioning base plate 10 itself is relatively heavy, coupled with the weight of the adjustment plate 20 and the shearing device 2, the friction between the positioning base plate 10 and the surface to be installed is greater, thereby effectively avoiding the relative displacement between the positioning base plate 10 and the installation surface, and the positioning base plate 10 can be regarded as fixed on the installation surface.

[0042] In some embodiments of the present application, Figure 2 As shown, one possible implementation of the adjustment assembly 30 is that the adjustment assembly 30 includes a transverse adjustment member 31, and the adjustment plate 20 is abutted against the transverse adjustment member 31 on both sides along the X-axis direction and the Y-axis direction. The transverse adjustment member 31 can drive the adjustment plate 20 to move relative to the positioning base plate 10 along the X-axis or the Y-axis, thereby realizing the position adjustment of the shearing device 2 in the X-axis and Y-axis directions. In order to ensure that the adjustment plate 20 can be adjusted in the overall position or the local position, the adjustment plate 20 has at least two transverse adjustment members 31 on both sides along the X-direction, and the adjustment plate 20 has at least two transverse adjustment members 31 on both sides along the Y-direction, and the transverse adjustment members 31 on both sides cooperate to adjust the position of the adjustment plate 20. Specifically, taking the X-axis direction as an example, when the adjustment plate 20 needs to be moved to the positive side of the X-axis for position adjustment, all the transverse adjustment members 31 on the negative side of the X-axis should be adjusted to the positive direction of the X-axis by the same distance to ensure that the adjustment plate 20 moves toward the positive direction of the X-axis as a whole. When the cutting device is skewed, the two adjustment components 30 located at the diagonal line need to be adjusted simultaneously to correct the position of the cutting device.

[0043] In some embodiments of the present application, Figure 2 As shown, the lateral adjustment member 31 includes a fixed seat 311 and an adjustment rod 312. The fixed seat 311 is connected to the positioning base plate 10. The adjustment rod 312 is adjustable and arranged on the fixed seat 311. The end of the adjustment rod 312 abuts against the positioning base plate 10. The position of the fixed seat 311 relative to the positioning base plate 10 is fixed. When the adjustment rod 312 is adjusted on the fixed seat 311, it can push the adjustment plate 20 to move through the abutment with the adjustment plate 20 to achieve the position adjustment of the cutting device.

[0044] Further, in some embodiments of the present application, Figure 2As shown, the fixing seat 311 is parallel to the side of the adjustment plate 20 and is connected to the positioning base plate 10. One fixing seat 311 corresponds to one adjustment rod 312. There is one fixing seat 311 at each of the two vertical side surfaces at the circumferential corner of the adjustment plate 20. That is to say, at this time, there is one lateral adjustment member 31 at each of the two vertical surfaces at the circumferential corner of the adjustment plate 20, which can adjust the position of the adjustment plate 20 in the X direction or the Y direction. Under normal circumstances, when the cutting device moves due to the vibration generated by cutting, it is not only accompanied by the overall displacement in the X-axis direction or the Y-axis direction, but also accompanied by skew. When adjusting the skew, it is necessary to give the adjustment plate 20 a torque to rotate in the opposite direction of the skew. The same force is applied. The closer the force application point is to the diagonal point, the greater the torque given to the adjustment plate 20 to rotate, and the easier it is to correct the skew of the shearing device 2. As for the overall skew of the shearing device 2, the overall position correction can be achieved by adjusting the lateral adjustment member 31 on the skewed side at the same time. It should be noted that when the adjustment plate 20 moves toward one side as a whole, the opposite side of the moving side becomes the calibration standard. As long as the adjustment plate 20 is adjusted in the opposite direction of the offset side until it contacts the adjustment rod 312 on the opposite side of the offset side, the calibration of the shearing device 2 is completed. For example, the shearing device 2 is offset toward the positive direction of the X direction as a whole. At this time, the adjustment rod 312 on the positive side of the X direction must also move toward the positive direction of the X direction relative to the fixed seat 311, while the adjustment rod 312 on the negative side of the X direction is not subjected to force, so the contact between the adjustment rod 312 on the negative side of the X direction and the adjustment plate 20 does not shift, and the position of the shearing device 2 when it is in the correct position is still maintained. Therefore, at this time, the adjustment rod 312 on the negative side of the X direction becomes the calibration standard. The position of the adjustment rod 312 on the positive side of the X direction is adjusted relative to the fixed seat 311 until the adjustment plate 20 contacts the adjustment rod 312 on the negative side of the X direction to complete the position adjustment of the shearing device 2. Similarly, when the shearing device 2 is skewed, the transverse adjustment piece 31 at one diagonal line is displaced, but the transverse adjustment piece 31 at the other diagonal line will not be displaced, and the transverse adjustment piece 31 at the other diagonal line becomes the standard for the correction of the shearing device 2, and it is sufficient to adjust the adjustment plate 20 to abut and align with the transverse adjustment piece 31 at the other diagonal line. When the shearing device 2 is accompanied by overall movement and deflection at the same time, there will always be an adjustment rod 312 at a corner line that will not be displaced relative to the matching fixed seat 311, and the transverse adjustment piece 31 at this corner is the correction reference, and the position correction of the shearing device 2 can be completed by adjusting the transverse adjustment pieces 31 at the other three diagonals until the adjustment plate 20 abuts against the transverse adjustment piece 31 at the correction reference corner.

[0045] Furthermore, in some embodiments of the present application, the distance between the contact point between the adjustment rod 312 and the adjustment plate 20 and the rotation corner of the adjustment plate 20 is less than or equal to 15 mm, which meets the need for overall movement of the adjustment plate 20 and is also easy to perform rotation correction on the adjustment plate 20.

[0046] In other embodiments of the present application, Figure 2 As shown, the fixing seat 311 is a corner seat, which is located at the corner of the adjusting plate 20 in the circumferential direction, and the two corner surfaces of the corner seat are respectively parallel to the two right-angled sides of the adjusting plate 20, and an adjusting rod 312 is movably provided on the two corner surfaces. Four fixing seats 311 are used, which reduces the number of parts and facilitates assembly.

[0047] Further, in some embodiments of the present application, Figure 2 As shown, the fixing seat 311 is provided with an internal thread, and the adjusting rod 312 is provided with an external thread, and the internal thread meshes with the external thread, so that the adjusting rod 312 can be rotated and moved on the fixing seat 311, and the length of the external thread on the adjusting rod 312 is 10cm, so the maximum range of movement of the adjusting rod 312 relative to the fixing seat 311 is 10cm, and the pitch of the internal thread and the external thread is 0.5mm, and the distance moved by the adjusting rod 312 relative to the fixing seat 311 after one rotation is 0.5mm. Therefore, the adjustment range of the lateral adjusting member 31 is greater than or equal to 0.5mm and less than or equal to 10cm.

[0048] In some embodiments of the present application, Figure 2 As shown, the adjustment assembly 30 also includes a vertical adjustment member 32, one side of which is in contact with the positioning base plate 10, and the other side of which can be lifted and pressed against the upper surface of the base of the shearing device 2, and a height-adjustable adjustment block 323 is provided between the base and the adjustment plate 20, and the vertical direction can be adjusted by adjusting the height of the adjustment block 323. Thus, the cutting device can be adjusted in three directions: X, Y and Z.

[0049] In some embodiments of the present application, Figure 2 As shown, the adjustment block 323 is a jack, and the height of the jack can be adjusted according to the height requirements of the cutting device. Alternatively, the adjustment block 323 includes multiple models, and the heights of the adjustment blocks 323 of different models are different. When the height of the cutting device needs to be adjusted, the adjustment blocks 323 of different models can be replaced. It can be understood that the height of the cutting device does not need to be adjusted under normal circumstances, unless the cutting device is initially installed to match the height of the production line, and the cutting device needs to be re-matched with the production line when the production line is subsequently modified.

[0050] In some embodiments of the present application, Figure 2As shown, the vertical adjustment member 32 includes a vertical adjustment rod 321 and a lifting member 322. The lifting member 322 can be moved up and down and is arranged on the vertical adjustment rod 321. The lower end of the vertical adjustment rod 321 abuts against the positioning base plate 10. The vertical adjustment rod 321 is provided with an external thread on the outer periphery, and the lifting member 322 is provided with an internal thread. The external thread is meshed with the internal thread, so that the vertical adjustment rod 321 can rotate relative to the lifting member 322, so that the lifting member 322 rises or falls relative to the vertical adjustment rod 321, and the adjustment is convenient.

[0051] In some embodiments of the present application, Figure 2 As shown, the calibration device 1 also includes a controller, a plurality of rotating power members and a plurality of distance sensors, the rotating power members and the distance sensors are coupled to the controller, and each adjusting rod 312 is provided with a distance sensor, which can measure the shortest distance between the adjusting rod 312 and the adjusting plate 20. The output end of each rotating power member is connected to an adjusting rod 312, which can drive the adjusting rod 312 to rotate to adjust the position of the adjusting rod 312 on the fixing seat 311, so as to realize the position calibration adjustment of the adjusting plate 20. It can be understood that when the adjusting plate 20 moves in one direction as a whole, such as the positive direction of the X direction, the distance sensor on the adjusting rod 312 in the positive direction of the X direction will transmit a signal of a decrease in distance to the controller, and the distance sensor on the adjusting rod 312 in the positive direction of the X direction will transmit a signal of an increase in distance to the controller, based on which the controller can recognize that the adjusting plate 20 moves in the positive direction of the X direction as a whole, and then the output end of the rotating power member connected to the positive adjusting rod 312 in the X direction will be controlled to rotate to drive the adjusting rod 312 to push the adjusting plate 20 to reset. It can be understood that the adjustment rod 312 moves 0.5mm relative to the fixed seat 311 for one rotation, and the controller can calculate how many circles the corresponding rotating power part rotates through the size of the moving distance transmitted by the distance sensor. Still taking the positive direction of the X direction as an example, when the adjustment plate 20 is offset toward the positive direction of the X direction as a whole, but one side is offset more toward the X direction and the other side is offset less toward the X direction, then the corresponding distance sensor will also transmit the offset to the controller in real time, and the controller controls the corresponding rotating power part to rotate the corresponding number of circles for position calibration, that is, in this case, the controller can control different rotating power parts to rotate different numbers of circles. When the adjustment plate 20 is skewed, the controller will receive the relatively reverse distance transmitted by the distance sensor located at the diagonal position. At this time, the controller will determine that the shearing device 2 is skewed, and then the controller will control the rotating power part located at the diagonal position to rotate to adjust the position of the adjustment plate 20, and calibrate the position of the shearing device 2. In this way, the position calibration of the shearing device 2 can be automatically performed in real time to ensure that the shearing device 2 will not be offset and the cutting quality of the plate is guaranteed.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
