Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment commissioning technology, and more specifically, to a flexible commissioning fixture. Background Technology

[0002] As a key piece of equipment in the metallurgical production line, the assembly accuracy of the looper in the finishing mill directly affects product quality. Traditional assembly processes suffer from the following technical defects: First, after assembly, the looper requires machine tool resources for dial indicator testing, necessitating repeated checks of the coplanarity parameters of the looper roll's swing arm arc surface. This testing method severely impacts the normal processing progress of the machine tool. Furthermore, current technology cannot achieve synchronous and precise adjustment of the swing arm angles on both sides of the looper, often requiring repeated adjustments through trial and error, which increases assembly time and makes it difficult to guarantee the symmetry of the swing arms. This machine tool-dependent debugging method wastes equipment resources and fails to meet the assembly efficiency requirements of modern production lines. Therefore, existing technologies urgently need improvement to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a flexible adjustment fixture to improve assembly efficiency, reduce machine tool resource usage, and achieve synchronous and precise adjustment of the swing arm angle.

[0004] To address the aforementioned problems, this invention provides a fitting for adjusting a looper. The looper includes a looper frame and two sets of swing arm frames.

[0010] Alternatively, during the sliding section's movement along the groove, the wedge-shaped section engages with the keyway to drive the rocker arm frame to rotate along the axis of rotation.

[0011] Optionally, the angle adjustment assembly includes two sets of ramps; one set of ramps moves clockwise along the axis of rotation towards one end of the looper as it extends along the axis of rotation; the other set of ramps moves counterclockwise along the axis of rotation as it extends counterclockwise along the axis of rotation towards one end of the looper.

[0020] like Figure 1-6As shown in the figure, an embodiment of the present invention provides a fitting for adjusting a looper. The looper includes a looper frame 3 and two sets of swing rod frames 5. The two sets of swing rod frames 5 are located at both ends of the looper frame 3, and the swing rod frames 5 are rotatably mounted on the rotating shaft at the end of the looper frame 3. Swing rods 6 are installed on the swing rod frames 5, and the upper surface of the swing rods 6 is an arc surface. The fitting includes an adjusting platform 1, a movable square box 7, and an angle adjustment component. The adjusting platform 1 is used to support the looper. The movable square box 7 is movably configured on the surface of the adjusting platform 1, and a detection component is provided on the top of the movable square box 7. The detection component is used to detect the height of the arc surfaces of the two swing rods 6. The angle adjustment component is located between the looper frame 3 and the swing rod frames 5, and is used to drive the swing rod frames 5 to rotate and adjust along the rotating shaft.

[0021] The debugging platform 1 refers to a support structure with a bearing surface and a slide rail 101 on its surface. Specifically, it can be implemented using a combination of welded steel plates and guide rails. Its function is to provide a stable reference surface for the loop assembly. The movable box 7 refers to a moving unit with a sliding component at the bottom and a detection device installed at the top. For example, displacement is achieved through the cooperation of a slider and the slide rail 101. Its function is to allow the detection component to cover the detection points of the swing arm 6 at different positions. The angle adjustment component refers to a device that changes the relative angle between the loop frame 3 and the swing arm frame 5 through a mechanical structure. For example, it can use an adjustment mechanism that uses a wedge block and a keyway 501. Its function is to achieve precise control of the angle of the swing arm frame 5.

[0022] Specifically, after the entire loop is fixed to the debugging platform 1, the movable square box 7 moves to the corresponding detection position of the swing arm 6, and the height data of the arc surface is measured by the detection component. When there is a deviation in the coplanarity of the two swing arms 6, the swing arm frame 5 is rotated by operating the angle adjustment component to change the height position of the swing arm 6 on the swing arm frame 5, so that the two swing arms 6 reach the predetermined angle. The detection component can measure the height of the two swing arms 6 separately as the position of the movable square box 7 changes, to ensure that the coplanarity error of the two swing arms 6 is within the allowable range.

[0023] This embodiment achieves adjustment through an angle adjustment component, reducing auxiliary working hours, decoupling the assembly and debugging process of the live set from the machine tool processing stage, and avoiding equipment resource conflicts.

[0024] Optionally, please combine Figure 4 The testing components include a testing frame and a dial indicator 10; one end of the testing frame is connected to the movable square box 7, and the other end is located above the swing arm 6; the dial indicator 10 is mounted on the testing frame and is used to test the height of the arc surface of the swing arm 6.

[0025] The testing frame refers to the rigid structure supporting the dial indicator 10, which can be implemented using a metal rod or a telescopic rod 8. Its function is to position the dial indicator 10 at the testing position above the pendulum rod 6. The dial indicator 10 is a mechanical displacement measuring instrument, which can be implemented using a pointer type or a digital instrument. Its function is to obtain the height data of the arc surface of the pendulum rod 6 through contact measurement. Specifically, the testing frame is fixed to the top of the movable box 7, with its extension suspended directly above the swing arm 6. The probe of the dial indicator 10 is vertically aligned with the arc surface of the swing arm 6. As the movable box 7 moves along the debugging platform 1, the testing frame drives the dial indicator 10 to different testing positions on the swing arm 6. By reading the measurement values ​​of the dial indicator 10 at different swing arms 6, the height difference between the arc surfaces of the two swing arms 6 can be directly compared, thereby determining whether their coplanarity meets the assembly requirements.

[0026] The above solution enables offline detection of the coplanarity of the looper arm 6, avoiding the occupation of machine tool resources. The combination structure of the detection frame and dial indicator 10 simplifies the measuring device, and the sliding function of the movable square box 7 allows a single detection assembly to cover the measurement needs of both sides of the looper arm 6, significantly shortening the adjustment time of the detection fixture.

[0027] Optionally, please combine Figure 6 The testing frame includes a telescopic rod 8 and a mounting rod 9; the telescopic rod 8 is mounted on the movable square box 7; one end of the mounting rod 9 is connected to the top of the telescopic rod 8, and the other end is connected to the dial indicator 10.

[0028] The telescopic rod 8 refers to a rod-shaped structure that can be adjusted in height along the vertical direction. Specifically, it can be implemented using a hydraulic telescopic structure or a threaded adjustment structure. By changing the extension length of the telescopic rod 8, the mounting rod 9 drives the dial indicator 10 to adapt to the different height requirements of the swing arm 6. The mounting rod 9 refers to the lateral support component used to fix the dial indicator 10, and can be implemented using a metal rod or a composite material rod.

[0029] Specifically, the telescopic rod 8, through its vertical height adjustment function, enables the mounting rod 9 to precisely align the dial indicator 10 with the arc-shaped detection position of the swing arm 6. During the looper debugging process, the operator can simultaneously adjust the height of the telescopic rod 8 and the lateral position of the mounting rod 9 according to the actual working conditions, so that the dial indicator 10 accurately contacts the arc surface of the swing arm 6 and obtains height data, allowing for multi-dimensional detection parameter adjustments without relying on machine tools.

[0030] Optionally, please combine Figure 6 The mounting rod 9 has a strip-shaped adjustment hole 901 at one end near the telescopic rod 8; the strip-shaped adjustment hole 901 is arranged along the extension direction of the mounting rod 9; the testing frame also includes a bolt 13; the bolt 13 passes through the strip-shaped adjustment hole 901 and can detachably connect the telescopic rod 8 and the mounting rod 9.

[0031] The strip-shaped adjustment hole 901 refers to an elongated through hole along the length of the mounting rod 9. It can be formed by machining a metal rod, and its length can be, for example, 200-300 mm. This structure provides movement space for adjusting the relative position of the mounting rod 9 and the telescopic rod 8. The bolt 13 refers to a threaded fastener, specifically a standard M8 or M10 bolt 13 with a nut. Tightening or loosening the bolt 13 controls the fixing state of the mounting rod 9 and the telescopic rod 8, thereby changing the horizontal position of the detection component.

[0032] Specifically, when the detection position of dial indicator 10 needs to be adjusted, bolt 13 is loosened, allowing mounting rod 9 to slide along the strip-shaped adjustment hole 901. For example, mounting rod 9 can be extended outward by 50 mm to accommodate a larger size loop. After adjustment, bolt 13 is tightened again to complete the fixation. The extension direction of the strip-shaped adjustment hole 901 is parallel to the axial direction of the swing arm 6, ensuring that the horizontal position adjustment of the detection component matches the detection requirements of the arc surface of the swing arm 6. In this embodiment, the cooperation between the strip-shaped adjustment hole 901 and bolt 13 allows the horizontal position of the detection component to be adaptively adjusted according to different loop sizes, avoiding repeated disassembly and reassembly. This achieves stepless adjustment of the detection component in the horizontal direction, enabling the same debugging fixture to accommodate multiple sizes of loops, shortening downtime caused by changing detection devices, and reducing reliance on machine tool positioning accuracy during debugging.

[0033] Optionally, please combine Figure 1-2 The surface of the debugging platform 1 is provided with two equal-height square boxes 2 at intervals. The equal-height square boxes 2 are equipped with bearing seats 4 that cooperate with the rotating bearing. The bearing seats 4 are provided with bearings that cooperate with the rotating shaft of the loop frame 3.

[0034] Among them, the equal-height square box 2 refers to the support structure with consistent height and spaced intervals. It can be made of cast iron or welded steel plate. The equal-height design ensures that the loop frame 3 maintains a horizontal reference during the commissioning process. The bearing seat 4 refers to the positioning component used to install the rotating bearing. It can be a cast iron base with positioning steps, which is fixedly connected to the equal-height square box 2 by bolts 13 to constrain the coaxiality of the rotating bearing.

[0035] Specifically, two equal-height square boxes 2 are spaced apart along the length of the looper 3 on the surface of the debugging platform 1, with a bearing seat 4 installed on the top of each square box. The rotating shafts at both ends of the looper 3 can be embedded into the corresponding bearing seats 4, and the looper 3 is stably supported by the cooperation between the bearing seats 4 and the rotating shafts. When the swing arm 5 rotates around the rotating shaft, the bearing seats 4 can limit the radial displacement of the rotating shaft, ensuring the consistency of the rotation axis. The spacing between the equal-height square boxes 2 can be adjusted according to the length of the looper 3, for example, by using a detachable installation structure to achieve spacing adjustment. This embodiment constructs a reference support system independent of the machine tool by setting equal-height square boxes 2 with bearing seats 4 on the debugging platform 1. This design eliminates the dependence on machine tool precision, allowing the assembly and debugging of the looper 3 and the swing arm 5 to be completed in a normal site. It realizes the physical separation of the looper assembly and debugging operation from the machine tool equipment, and does not require the occupation of machine tool processing resources during the debugging process. The support system composed of bearing housing 4 and equal-height square box 2 can stably maintain the coaxiality of the rotating shaft and ensure the motion accuracy when the angle of the swing arm frame 5 is adjusted, thereby achieving the same assembly quality as machine tool debugging in a non-machine tool environment.

[0036] Optionally, please combine Figure 3-5 The angle adjustment component includes a slant key 11, which includes a sliding section 1101 and a wedge-shaped section 1102. The bearing seat 4 has a groove 401 at its end that mates with the sliding section 1101. The sliding section 1101 is slidably fitted into the groove 401 along the extension direction of the rotating shaft. The rocker arm frame 5 has a keyway 501 that mates with the wedge-shaped section 1102. When the sliding section 1101 moves along the extension direction of the rotating shaft, the wedge-shaped section 1102 moves in the keyway 501 along the extension direction of the rotating shaft.

[0037] The inclined key 11 refers to an adjusting component with a sliding section 1101 and a wedge-shaped section 1102. It can be formed as a single structure using metal material. The sliding section 1101 slides within the groove 401 to transmit displacement, and the wedge-shaped section 1102 engages with the keyway 501 to produce an angle change. The groove 401 refers to a guide structure at the end of the bearing seat 4, which can be formed using milling or casting processes. The extension direction of the groove 401 is parallel to the axis of rotation, limiting the movement trajectory of the sliding section 1101. The keyway 501 refers to a wedge-shaped mating structure inside the rocker arm frame 5, which can be formed using wire cutting or electrical discharge machining. The inclined surface of the keyway 501 contacts the inclined surface of the wedge-shaped section 1102, generating rotation of the rocker arm frame 5 through relative sliding.

[0038] Specifically, the sliding section 1101 is fitted into the groove 401 at the end of the looper 3, allowing it to slide linearly along the axis of rotation. When the sliding section 1101 is displaced by an external force, the wedge-shaped section 1102, which is fixedly connected to the sliding section 1101, moves synchronously. Since the inclined surface of the wedge-shaped section 1102 contacts the inclined surface of the keyway 501 of the swing arm 5, the axial movement of the wedge-shaped section 1102 is converted into the radial displacement of the swing arm 5, thereby forcing the swing arm 5 to rotate around the axis of rotation. By controlling the moving distance of the sliding section 1101, the relative angle between the looper 3 and the swing arm 5 can be precisely adjusted. For example, when the sliding section 1101 moves away from the center of rotation, the inclined surface of the wedge-shaped section 1102 pushes the side wall of the keyway 501, causing the swing arm 5 to rotate clockwise; when the sliding section 1101 moves in the opposite direction, the swing arm 5 returns to its original position counterclockwise. This embodiment achieves rapid and precise adjustment of the angle between the looper 3 and the swing arm 5, allowing assembly and debugging to be completed without occupying machine tool resources. The sliding adjustment method of the inclined key 11 structure replaces the traditional grinding process, avoiding repeated disassembly and machine tool measurement operations, effectively shortening the assembly cycle. At the same time, the guiding cooperation between the sliding section 1101 and the groove 401 ensures the linear controllability of the angle adjustment, and the inclined surface contact design between the wedge section 1102 and the keyway 501 converts axial displacement into precise angular changes, ensuring the adjustment accuracy of the swing arm 5's rotation angle.

[0039] Optionally, during the sliding process of the sliding section 1101 along the groove 401, the wedge section 1102 drives the rocker arm frame 5 to rotate along the axis by cooperating with the keyway 501.

[0040] The sliding segment 1101 refers to a structural component that achieves linear displacement within the groove 401 along the direction of rotation. Specifically, it can be implemented using a metal block with a guide boss. Its cross-sectional shape forms a clearance fit with the groove 401, ensuring a stable trajectory during sliding. The wedge-shaped segment 1102 refers to a transition structure with an inclined contact surface. Specifically, it can be implemented using a metal block with a trapezoidal cross-section. Its inclined angle, in conjunction with the keyway 501, forms a displacement conversion mechanism, converting the linear motion of the sliding segment 1101 into the rotational motion of the swing arm 5. The keyway 501 refers to a guide structure formed inside the swing arm 5 that engages with the wedge-shaped segment 1102. Specifically, it can be implemented using a rectangular or trapezoidal cross-section groove 401. Its extending direction forms a preset angle with the axis of rotation, constraining the movement path of the wedge-shaped segment 1102 and forcing the swing arm 5 to deflect at an angle.

[0041] Specifically, when the sliding section 1101 is driven by an external force to slide along the groove 401, the wedge-shaped section 1102 generates a lateral displacement component due to the geometric constraint of the sidewall of the keyway 501. Since the extension direction of the keyway 501 forms a non-perpendicular angle with the axis of rotation, the movement of the wedge-shaped section 1102 forces the swing arm 5 to rotate around the axis of rotation, thereby changing the relative angle between the swing arm 5 and the loop frame 3. This process directly achieves angle adjustment through the geometric fit of the mechanical structure, without relying on repeated calibration by external measuring equipment.

[0042] Optionally, the angle adjustment assembly includes two sets of ramp keys 11; when one set of ramp keys 11 moves towards the looper 3 along the extension direction of the rotating shaft, the swing arm 5 rotates clockwise along the rotating shaft; when the other set of ramp keys 11 moves towards the looper 3 along the extension direction of the rotating shaft, the swing arm 5 rotates counterclockwise along the rotating shaft.

[0043] The two sets of inclined keys 11 work together to prevent the swing frame from swinging erroneously during operation. The two sets of inclined keys 11 control the clockwise and counterclockwise rotation of the swing frame respectively. Therefore, the two sets of inclined keys 11 work together to lock the swing frame.

[0044] Specifically, when the swing frame needs to be adjusted clockwise, the corresponding slant key 11 (clockwise driven slant key 11) is controlled to move to the side of the loop frame 3, and another set of slant keys 11 is withdrawn away from the loop frame 3. When the position of the swing arm 6 is adjusted to the correct position and the slant key 11 is locked, the withdrawn slant key 11 is pushed back in to lock, thereby ensuring that the swing frame will not rotate on its own.

[0045] Optionally, the key 11 includes a sliding section 1101 and a wedge-shaped section 1102; the wedge-shaped section 1102 has a pin hole; the wedge-shaped section 1102 is connected to the swing frame by a pin 12.

[0046] The pin hole refers to a through hole penetrating the wedge-shaped section 1102, which can be achieved by drilling. It is used to accommodate the pin 12 to achieve a fixed connection between the inclined key 11 and the rocker arm frame 5. The pin 12 is a cylindrical connector, which can be made of metal. It is inserted into the pin hole and passes through the corresponding hole in the rocker arm frame 5 to limit the relative displacement between the inclined key 11 and the rocker arm frame 5.

[0047] Specifically, when the sliding section 1101 of the inclined key 11 slides along the groove 401 of the bearing seat 4, the wedge section 1102 drives the rocker arm frame 5 to rotate around the pivot axis through the keyway 501, thereby adjusting the angle of the rocker arm 6. After adjustment, the pin 12 is inserted into the pin hole of the wedge section 1102 and passes through the corresponding hole of the rocker arm frame 5, so that the inclined key 11 and the rocker arm frame 5 form a rigid connection, preventing the inclined key 11 from being displaced due to vibration or external force during subsequent debugging or use.

[0048] In some specific embodiments, the pin holes may be located in the middle or near the end of the wedge-shaped segment 1102, for example, two pin holes may be symmetrically distributed along the length of the wedge-shaped segment 1102 to enhance the stability of the connection. The pin 12 may be a threaded pin or a spring pin, for example, to achieve a detachable connection through threaded engagement, facilitating repeated adjustments.

[0049] Optionally, the debugging platform 1 is provided with a slide rail 101; the movable box 7 is slidably set between a first position and a second position of the slide rail 101, and when the movable box 7 is in the first position or the second position of the slide rail 101, the detection component is located at the detection position of one of the swing arms 6.

[0050] The slide rail 101 refers to a linear guide structure installed on the surface of the debugging platform 1. Specifically, it can be implemented using a linear guide rail or a T-slot structure, and is used to guide the movable box 7 to slide along a predetermined path. The sliding setting of the movable box 7 on the slide rail 101 refers to the displacement achieved through the cooperation of the slider and the guide rail. Specifically, it can be achieved by the engagement of rollers and grooves 401, ensuring stability during movement. The detection position refers to the spatial position where the detection component and the arc surface of the swing arm 6 form an effective detection distance. Specifically, it can be achieved using a limit block or a positioning pin, used to precisely limit the stopping position of the movable box 7.

[0051] Specifically, the slide rail 101 is laid parallel to the length of the debugging platform 1, and the bottom of the movable box 7 is equipped with a sliding component that matches the slide rail 101. When it is necessary to detect the arc height of the two sets of swing arms 6, the movable box 7 can slide along the slide rail 101 from the first position to the second position, causing the detection components to align with the detection positions of the two sets of swing arms 6 respectively. For example, limit blocks are set at both ends of the slide rail 101. When the movable box 7 contacts the block, the detection components automatically align with the detection area of ​​the swing arm 6. Thus, the synchronous detection of the two sets of swing arms 6 can be completed without repeatedly adjusting the position of the detection equipment.

[0052] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
