Description

Technical Field

[0001] The present invention relates to the technical field of milling and grinding and polishing auxiliary parts, and more particularly to a straightening blade clamping device, a processing system and a processing method. Background Art

[0002] The rectifier blade blank is made of stainless steel sheet material, and its processing is as follows: first, the plate is milled to form the initial blade outline, then the blade basin and blade back profiles and subsequent processing benchmarks are rolled out using a cold rolling process. The blade body surface is then manually polished to ensure the blade profile, size, and surface roughness. Finally, the process benchmarks and excess parts are removed to obtain the finished blade. The blade body polishing process involves manual polishing by the operator using a polishing machine and a surface measuring tool. This process requires repeated polishing and repeated testing. The process is difficult to operate, has low processing efficiency, and is difficult to ensure processing consistency. The annual production of these blades is large, and the polishing process has become a major bottleneck restricting their production and delivery.

[0003] To reduce the difficulty of manual operation and improve blade processing efficiency and quality, CNC milling and grinding and polishing technologies are proposed to replace manual polishing. Since sheet extrusion deformation is difficult to control during the cold rolling process, there is significant fluctuation in the relative position between the blade profile and the process datum after cold rolling, and the blade profile margin after cold rolling is small. When the blade profile is positioned and clamped using the process datum, milling and grinding of the blade profile occurs, leaving some blade profiles without milling and grinding margins, resulting in the scrapping of the blade. Increasing the milling margin also leads to increased tool consumption, reduced processing efficiency, and increased milling deformation, making it difficult to replace the original manual polishing process with milling and grinding and polishing. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that it is difficult to replace the original manual polishing process with milling and grinding and polishing, and to provide a rectifier blade clamping device, a processing system and a processing method to replace the original manual polishing process with milling and grinding and polishing.

By adjusting the adjustable clamping system, the measuring system is reset to zero, thereby transferring the theoretically correct position on the counter-measurement part to the part installed on the adjustable clamping system, that is, allowing the part to have a processing allowance, avoiding the problem of having no milling and polishing allowance on the blade body surface when the blade body surface is milled and polished after the blade is positioned and clamped according to the process reference, thereby realizing the replacement of the original manual polishing process with milling and polishing.

Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution in which both A and B are satisfied.

[0025] Example 1 This embodiment is the first embodiment of the rectifier blade clamping device. Figure 1 and Figure 2 Shown, comprise base plate 100, first zero point positioning system 200, adjustable clamping system 300, measuring system 400 and have machining allowance alignment piece 500, first zero point positioning system 200 and measuring system 400 are all installed and connected on the base plate 100, adjustable clamping system 300 is installed and connected on the first zero point positioning system 200, and the second zero point positioning system is installed and connected on the processing machine tool.The first zero point positioning system 200 uses prior art zero point positioning system, and zero point positioning system is a unique positioning and locking device, can keep workpiece from one station to another station, one process to another process, or one machine tool to another machine tool, and zero point remains unchanged.Can save the auxiliary time of re-aligning zero point like this, ensure the continuity of work, improve work efficiency.The first zero point positioning system 200 comprises manual zero point positioning chuck and zero point positioning pallet in the present embodiment, and the zero point positioning pallet is detachably connected with the manual zero point positioning chuck. The repeatability of the first zero-point positioning system 200 is within 0.005 mm. An appropriate zero-point positioning system can be selected based on the actual machining accuracy and actual size of the part.

[0026] like Figure 3 and Figure 4As shown, the measurement system 400 includes a meter frame 410 and a first distance measuring mechanism 420, a second distance measuring mechanism 430, and a third distance measuring mechanism 440, all of which are mounted on the meter frame 410. The meter frame 410 is mounted on the base plate 100. The first distance measuring mechanism 420 and the second distance measuring mechanism 430 are located in the same horizontal plane and are spaced apart in the horizontal direction. The third distance measuring mechanism 440 is located at a different height from the first distance measuring mechanism 420. The first distance measuring mechanism 420 and the second distance measuring mechanism 430 can be used to determine the inclination of a part about a third direction. The readings of the first distance measuring mechanism 420 and the third distance measuring mechanism 440 can be used to determine the verticality of the part. The first distance measuring mechanism 420, the second distance measuring mechanism 430, and the third distance measuring mechanism 440 can be used to adjust the measuring surface of the part to be consistent with the zeroing surface of the meter. This eliminates the need for precise measurement of the part's position, making it simpler and more convenient to provide a machining allowance for the part.

[0027] In this embodiment, Figure 3 As shown, the gauge frame 410 is fixed to the base plate 100 via screws and pins. The first, second, and third distance measuring mechanisms 420, 430, and 440 correspond to the two blade sections to be inspected. The first and second distance measuring mechanisms 420, 430, and 440 are located on one of the blade sections, at the left and right ends of the part along the X-direction, that is, at the leading and trailing edges, respectively. The third distance measuring mechanism 440 is located on the other blade section, designed to be positioned at the center of the blade. The first, second, and third distance measuring mechanisms 420, 430, 440 are all configured as dial indicators. Using these dial indicators provides more accurate readings of the part's measurement position. This dial indicator arrangement adjusts the part's rotational displacement around the Z-axis by using the deviation between the leading and trailing edge gauges, and adjusts the part's rotational displacement around the X-axis by using the deviation between the upper and lower sections, thereby achieving rotational alignment of the part around both the Z and X axes.

[0028] like Figure 3 and Figure 4 As shown, the adjustable clamping system 300 includes a movable component 310, an X-axis rotating component 320, and a Z-axis rotating component 330, which are sequentially mounted and connected. The movable component 310 is mounted and connected to the first zero-point positioning system 200. By setting the movable component 310, the X-axis rotating component 320, and the Z-axis rotating component 330, the position of the part mounted on the adjustable clamping system 300 is adjusted step by step. The X-axis, Y-axis, and Z-axis use the X, Y, and Z axes in a three-dimensional spatial coordinate system.

[0029] The working principle of a rectifier blade processing system in this embodiment is as follows: The counter-measurement part 500 with machining allowance is installed on the first zero point positioning system 200, the measuring system 400 is zeroed, the counter-measurement part 500 is removed, and the part is installed on the adjustable clamping system 300, and the adjustable clamping system 300 with the part installed is installed on the first zero point positioning system 200. By adjusting the adjustable clamping system 300, the measuring system 400 is reset to zero, so that the theoretical correct position on the counter-measurement part 500 is transferred to the part installed on the adjustable clamping system 300, that is, the part has a machining allowance. Through the simple operation of the three dial indicators at zero, there is no need to accurately locate the overall position of the blade, which can avoid the problem of no milling and grinding allowance on the blade part when the blade surface is milled and polished after the blade is positioned and clamped according to the process reference, thereby realizing the replacement of the original manual polishing process with milling and polishing.

[0030] Example 2 This embodiment is a second embodiment of a straightening blade processing system. This embodiment is similar to the first embodiment, except that Figure 5 and Figure 7 As shown, the movable component 310 includes a base 311, a mounting base 312, a movable fixing assembly 313, a first movable adjustment screw 314 and a second movable adjustment screw 315. The base 311 is installed and connected to the first zero point positioning system 200. The mounting base 312 is slidably connected to the base 311. The mounting base 312 slides relative to the base 311 along the second direction. The second direction is the direction of the connection between the mounting base 312 and the third distance measuring mechanism 440. The second direction is specifically the direction of the connection between the center of the mounting base 312 and the center of the third distance measuring mechanism 440, that is, Figure 7 In the Y direction, the first movable adjustment screw 314 and the second movable adjustment screw 315 are both threadedly connected to the base 311 along the second direction. The two ends of the mounting base 312 abut against the first movable adjustment screw 314 and the second movable adjustment screw 315, respectively, and the mounting base 312 can be fixed by the movable fixing assembly 313. The first movable adjustment screw 314 and the second movable adjustment screw 315 are rotated to push the mounting base 312 to slide on the base 311, fine-tuning the position of the part along the second direction. The position of the mounting base 312 is then fixed by the movable fixing assembly 313.

[0031] In this embodiment, the movable fixing assembly 313 is a movable clamping screw. Specifically, two rows of slide rails are designed below the mounting base 312. The inner and bottom surfaces of the slide rails mate with the base 311, and their sliding direction is aligned with the Y-axis direction of the component. The mounting base 312 has waist-shaped holes on the front and back sides of its bottom, through which the movable clamping screw is installed on the base 311. Rotating the first movable adjustment screw 314 and the second movable adjustment screw 315 drives the mounting base 312 to move along the component's Y-axis. After moving to the desired position, the first and second movable adjustment screws 314 and 315 are locked and the movable clamping screws are tightened, allowing the mounting base 312 to fix the component's freedom of movement along the Y-axis.

[0032] like Figure 5 and Figure 8 As shown, the X-axis rotating component 320 includes a cradle 321, an X-axis fixing assembly 322, an adjusting rod 323, a first X-axis adjusting screw 324 and a second X-axis adjusting screw 325. The cradle 321 is rotatably connected to the mounting base 312. The cradle 321 rotates relative to the mounting base 312 along a first direction. The first direction is perpendicular to the second direction, and the first direction is coplanar with the second direction. The first direction is also Figure 6 and Figure 7 In the X-direction, an adjustment rod 323 is provided on the cradle 321. A first X-axis adjustment screw 324 and a second X-axis adjustment screw 325 are both threadedly connected to the mounting base 312. The first X-axis adjustment screw 324 and the second X-axis adjustment screw 325 are both arranged tangentially to the rotation axis of the cradle 321, and in this embodiment, are arranged along the Y-direction. The two sides of the adjustment rod 323 abut the first X-axis adjustment screw 324 and the second X-axis adjustment screw 325, respectively. The cradle 321 can be fixed by the X-axis fixing assembly 322. The Z-axis rotating component 330 is mounted and connected to the cradle 321. By rotating the first X-axis adjustment screw 324 and the second X-axis adjustment screw 325, the adjustment rod 323 is pushed to rotate the cradle 321 in the first direction, thereby fine-tuning the position of the component rotated in the first direction. The position of the cradle 321 is then fixed by the X-axis fixing assembly 322.

[0033] In this embodiment, the X-axis fixing assembly 322 is a vertical compression screw. Specifically, the mounting base 312 is connected to the cylinders on both sides of the cradle 321 through cylindrical holes on the left and right sides. The cylindrical holes are slotted on one side. Specifically, a compression block is slidably connected to the mounting base 312. The vertical compression screw passes through the compression block and connects to the mounting base 312. The size of the cylindrical hole can be adjusted by the compression screw, thereby clamping the cylindrical surfaces on both sides of the cradle 321. Two ear-shaped structures are designed on one side of the mounting base 312 for installing the first X-axis adjustment screw 324 and the second X-axis adjustment screw 325. A square groove is designed on one side of the cylindrical surface of the cradle 321. The square groove is used to install a square adjustment rod 323. The adjustment rod 323 is placed between the two ear-shaped structures of the mounting seat 312. The adjustment rod 323 is driven by the first X-axis adjustment screw 324 and the second X-axis adjustment screw 325 to rotate the cradle 321 around the X-axis of the part to a suitable position. Then, the first X-axis adjustment screw 324 and the second X-axis adjustment screw 325 are locked and the vertical clamping screw is tightened to fix the freedom of rotation of the part around the X-axis.

[0034] like Figure 6 and Figure 7 As shown, the Z-axis rotating component 330 includes a positioning component 331, a Z-axis fixing component 332, a first Z-axis adjusting screw 333 and a second Z-axis adjusting screw 334. The positioning component 331 is rotatably connected to the cradle 321. The positioning component 331 rotates relative to the cradle 321 along a third direction. The third direction is perpendicular to both the second direction and the first direction. The third direction is also Figure 6 In the Z-direction, first Z-axis adjustment screw 333 and second Z-axis adjustment screw 334 are both threadedly connected to cradle 321. Both sides of positioning assembly 331 abut against first and second Z-axis adjustment screws 333, 334, respectively. Positioning assembly 331 can be secured via Z-axis fixing assembly 332. By securing the part with positioning assembly 331, rotating first and second Z-axis adjustment screws 333, 334 pushes positioning assembly 331 to rotate about the third direction, fine-tuning the position of the part rotated about the third direction. Positioning assembly 331 is then fixed via Z-axis fixing assembly 332.

[0035] like Figure 5 and Figure 7As shown, the positioning assembly 331 includes a cylindrical positioning plate 331a, a movable pressure plate 331b, a tightening screw 331c, an adjusting protrusion 331d and a positioning pin 331e for cooperating with the part positioning hole. The cylindrical positioning plate 331a is rotatably connected to the cradle 321, and the cylindrical positioning plate 331a rotates relative to the cradle 321 along the third direction. The movable pressure plate 331b is rotatably connected to the cylindrical positioning plate 331a. The movable pressure plate 331b is rotatably connected to the cylindrical positioning plate 331a through a hinge. The movable pressure plate 331b is used to rotate. To compress the parts, the movable pressure plate 331b can be fixed by the compression screw 331c. The cylindrical positioning plate 331a and the movable pressure plate 331b are both provided with a mating surface for abutting against both sides of the parts. The positioning pin 331e is slidably connected to the cylindrical positioning plate 331a. Specifically, the outer circle of the cylindrical positioning plate 331a adopts a partial cylindrical surface structure design, and the middle part of the cylindrical positioning plate 331a is designed to be a mating surface that matches the blade process surface, and the positioning pin 331e is installed to match the positioning hole on the blade process surface to achieve The part is initially positioned on the fixture, and the positioning hole is located in the middle position of the blade along the X direction. The positioning pin 331e is passed through the positioning hole to position the part in the X direction, so that the middle position of the blade along the X direction is aligned with the third distance measuring mechanism 440. A cylindrical positioning block is provided on the cradle 321. The inner circle of the cylindrical positioning block adopts a cylindrical surface structure design that matches the outer circle of the cylindrical positioning plate 331a. The inner circle of the cylindrical positioning block fits the outer circle of the cylindrical positioning plate 331a. The outer cylindrical surface part of the cylindrical positioning plate 331a is installed on the cradle 3 The cylindrical positioning blocks on 21 form a cylindrical pair. When the cylindrical positioning plate 331a rotates, the cylindrical positioning blocks guide the rotation of the cylindrical positioning plate 331a. The cylindrical positioning plate 331a can be fixed by the Z-axis fixing component 332. In this embodiment, the Z-axis fixing component 332 is configured as a horizontal fixing screw. The top of the cylindrical positioning plate 331a is designed with a circular arc groove symmetrical around the rotation center on both sides for installing the horizontal fixing screw.

[0037] Example 3 This embodiment is the first embodiment of a straightening blade processing system. Figure 1 and Figure 2 As shown, the rectifying blade clamping device provided by Example 1 or Example 2 includes a processing machine tool and the rectifying blade clamping device provided by Example 1 or Example 2, and the processing machine tool is installed and connected with a second zero-point positioning system, and the second zero-point positioning system uses the same prior art zero-point positioning system as the first zero-point positioning system 200.

[0038] The rectifying blade processing system of the present invention moves the adjusted parts together with the adjustable clamping system 300 to the second zero-point positioning system, uses the zero-point positioning system to keep the zero point unchanged before and after the transfer, and starts the processing machine to process the parts, thereby avoiding the problem of no milling and polishing allowance on the blade surface when the blade surface is milled and polished after the blade is positioned and clamped according to the process reference, and realizes the replacement of the original manual polishing process with milling and polishing.

[0039] Example 4 This embodiment is the first embodiment of a method for processing a rectifier blade. Figure 1 and Figure 2 As shown, the rectifying blade processing system provided by the first or second embodiment includes the following steps: S1: Installing the alignment member 500 on the first zero point positioning system 200; S2: Zero the measuring system 400 to ensure that the pressure of each dial gauge is about 0.2; S3: Remove the alignment member 500 and install the adjustable clamping system 300 with the installed parts on the first zero point positioning system 200; S4: Adjust the adjustable clamping system 300 to return the measuring system 400 to zero and fix the part; Step S4 specifically includes the following steps: Figure 3 As shown: S41: Adjust the moving component 310 to move the part along the second direction. Figure 3 In the Y direction, which is the direction of the line connecting the part and the measuring system 400, readings are obtained on the first distance measuring mechanism 420, the second distance measuring mechanism 430, and the third distance measuring mechanism 440, and the part is locked to constrain the freedom of movement of the part along the second direction; S42: Adjust the Z-axis rotating component 330 to allow the part to rotate around the third direction, which is Figure 2 In the Z direction, that is, the vertical direction, the reading values ​​of the first distance measuring mechanism 420 and the second distance measuring mechanism 430 are made consistent, and the locking part constrains the rotational freedom of the part around the third direction; S43: Adjust the X-axis rotating component 320 to allow the part to rotate around the first direction, which is Figure 3 and Figure 6 In the X direction, the readings of the first distance measuring mechanism 420 and the third distance measuring mechanism 440 are made consistent, and the locking part constrains the rotational freedom of the part around the first direction; S44: Unlock the freedom of movement of the part along the second direction, adjust the moving component 310, allow the part to move along the second direction, return the first distance measuring mechanism 420, the second distance measuring mechanism 430 and the third distance measuring mechanism 440 to zero, and fix the part.

[0040] In this embodiment, the adjustment method for the straightening blade is to first adjust the rotation amount of the part around the Z axis according to the readings of the two dial indicators on the leading edge and the trailing edge, so that the readings of the two indicators are consistent, and the part rotating around the Z axis is locked. Then, the readings of the dial indicators of the upper and lower sections are observed, and the dial indicator readings of the upper and lower sections are adjusted to be consistent. The values ​​here are adjusted to be consistent to match the machining allowance, that is, if the machining allowance is 0.1mm, the difference in values ​​between the dial indicators is allowed to be within 0.02, and the part rotating around the X axis is locked. Finally, the part is adjusted to move along the Y axis so that the readings of the three dial indicators are as close to 0 as possible, that is, the theoretical correct position, and the part is fixed to move along the Y axis. At this time, the posture of the part on the fixture has been adjusted to the correct position.

[0041] S5: Remove the adjustable clamping system 300 with the parts installed, install it on the second zero point positioning system, start the processing machine tool, and perform processing.

[0042] The blade process datum is generally set to the bottom surface of the blade. Since the blade process datum will be deformed after cold rolling, positioning the blade by the process datum will result in excessive machining allowances in some parts of the blade while no machining allowances in other parts. At this time, if the blade needs to be precisely positioned, complex equipment needs to be used or the operation is relatively cumbersome. The rectifying blade processing method of the present invention uses a first zero-point positioning system 200, a measuring system 400, and an adjustable clamping system 300 to convert the theoretically correct position on the watch 500 to the part installed on the adjustable clamping system 300, so that the part has a machining allowance, and transfers the accurately adjusted part to a processing machine tool equipped with a second zero-point positioning system through the first zero-point positioning system 200, so that the part can be adjusted to the correct processing position offline, so that the part has a machining allowance during processing. It solves the problem of difficulty in positioning the blades due to deformation of the process base after cold rolling. It also eliminates the need to use complex equipment to measure the specific shape and position of the blades. It makes it easier to have machining allowances during processing, ensuring the allowances for milling or grinding and polishing, and replacing the original manual polishing process with milling and grinding and polishing.
