Description

Technical Field

[0001] The present invention relates to the technical field of machining tooling, and in particular to a plate clamping tooling and a clamping method. Background Art

[0002] In some fields, such as aerospace, machined workpieces are often thin-walled and made of difficult-to-machine materials such as high-temperature alloys and titanium alloys. Machining thin-walled workpieces often presents two challenges: vibration generated during machining and deformation of the thin-walled structure caused by stress release after fixture removal.

[0003] Therefore, the processing of thin-walled structures usually requires auxiliary support tooling. In the existing technology, wax injection is used to support the interior of thin-walled structures to achieve the purpose of controlling vibration and deformation. However, this method is only suitable for thin-walled structures with internal cavities and is not suitable for processing plate-like thin-walled structures.

[0004] Therefore, it is urgent to propose a plate clamping tool and a clamping method to solve the above problems. Summary of the Invention

[0005] An object of the present invention is to provide a plate clamping tool, which is easy to load and unload and can achieve vibration control and deformation control of the plate during processing.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0013] The plate clamping fixture provided by the present invention fixes the position of the plate through a locking seat, clamps the clamping assembly on the plate, and uses a traction rope to pass through the first wire member in the clamping assembly so that the traction rope applies pressure to the plate. The tension on the traction rope is adjusted by adjusting the second wire members on both sides of the clamping seat so that the force on the plate in the direction perpendicular to the plate is zero, and only pressure is applied to the plate in a direction coinciding with the plate surface, ensuring that the plate is in a state of force balance. Therefore, the clamping and removal of the plate clamping fixture will not affect the stress characteristics of the plate, thereby achieving the purpose of controlling the deformation of the plate. According to the natural mode of the plate, by moving the position of the third wire member in the adjustment assembly, the tension on the traction rope is changed so that the traction rope provides the plate with an appropriate amount of pressure, thereby attracting all vibrations generated during the plate processing process to the traction rope, thereby reducing the modal frequency of the plate. By reducing the modal frequency of the plate, the main excitation frequency range during the processing process can be avoided, thereby significantly reducing the amplitude of the plate, achieving the effect of controlling the vibration of the plate. In addition, each component in the panel clamping tool adopts a modular design, which is easy to assemble and disassemble, and can quickly change different traction rope passage methods according to usage needs.

[0057] Example 1

[0058] See also Figure 1 and Figure 2 In this embodiment, a rectangular plate 10 is used as an example to illustrate the plate clamping tool. In other embodiments, the plate 10 may also be a square, pentagon, hexagon or other irregular shape, which is not specifically limited here.

[0059] The panel clamping tool provided in this embodiment includes a base 100, at least one clamping assembly 200, a plurality of sliding assemblies 300, an adjusting assembly 400 and a traction rope 500, wherein a locking seat 110 is provided on the base 100, the locking seat 110 is used to clamp one side of the panel 10, the clamping assembly 200 is used to clamp the side of the panel 10, the clamping assembly 200 is provided with a first wire-passing member 210, the sliding assemblies 300 are both provided on the base 100, a sliding assembly 300 is provided on both sides of the locking seat 110, the sliding assembly 300 is provided with a second wire-passing member 310, the adjusting assembly 400 is provided on the base 100, the adjusting assembly 400 is provided with a third wire-passing member 410, the third wire-passing member 410 can move relative to the base 100, the traction rope 500 passes through the first wire-passing member 210, the second wire-passing member 310 and the third wire-passing member 410, and the ends of the traction rope 500 are connected to form a closed loop.

[0060] The above-mentioned panel clamping tool fixes the position of the panel 10 through the locking seat 110, and clamps the clamping assembly 200 on the panel 10, and uses the traction rope 500 to pass through the first wire-passing piece 210 in the clamping assembly 200, so that the traction rope 500 applies pressure to the panel 10, and adjusts the tension of the traction rope 500 by adjusting the second wire-passing pieces 310 on both sides of the locking seat 110, so that the force on the panel 10 in the direction perpendicular to the panel 10 is zero, and only pressure is applied to the panel 10 in a direction coinciding with the panel surface, ensuring that the panel 10 is in a state of force balance, so that the clamping and removal of the panel clamping tool will not affect the stress characteristics of the panel 10, thereby achieving the purpose of controlling the deformation of the panel 10. According to the natural mode of the panel 10, by moving the position of the third wire member 410 in the adjustment assembly 400, the tension on the traction rope 500 is changed, so that the traction rope 500 provides the panel 10 with an appropriate amount of pressure, thereby attracting the vibration generated during the processing of the panel 10 to the traction rope 500, thereby reducing the modal frequency of the panel 10. By reducing the modal frequency of the panel 10, the main excitation frequency range during the processing can be avoided, thereby significantly reducing the amplitude of the panel 10 and achieving the effect of controlling the vibration of the panel 10. In addition, each component in the panel clamping fixture adopts a modular design, which is simple to assemble and disassemble, and can quickly change different traction rope 500 passage methods according to usage needs.

[0061] See also Figure 1 and Figure 2 In this embodiment, the base 100 is a square plate-shaped structure. The base 100 is provided with a plurality of longitudinal fixing holes 101, transverse fixing holes 102, and circular fixing holes 103 for securing components connected to the base 100. Optionally, the longitudinal fixing holes 101 are located on both sides of the base 100 in the transverse direction (the x-axis direction in the figure), with three rows and eight columns on each side; the transverse fixing holes 102 are located in the middle of the base 100 in the longitudinal direction (the y-axis direction in the figure), with a total of two rows and seventeen columns; and the circular fixing holes 103 are located on both sides of the transverse fixing holes 102, with nine rows and nine columns on each side. By providing multiple rows and columns of fixing holes, the fixing holes can be selected as needed to secure the components in the appropriate position.

[0062] See also Figures 1 to 3The locking seat 110 includes two clamping blocks 111, which are connected to the base 100. The two clamping blocks 111 are used to cooperate in clamping the plate 10. The clamping block 111 is in the shape of a rectangular parallelepiped, and a plurality of through holes for passing bolts are respectively provided along the vertical direction (z-axis direction in the figure) and the longitudinal direction of the clamping block 111. The clamping block 111 is fixed to the base 100 by passing the vertical through holes on the clamping block 111 and the longitudinal fixing holes 101 on the base 100, and the bolt base 100 is locked by a nut. The plate 10 is clamped between the two clamping blocks 111, and the two clamping blocks 111 are clamped to the plate 10 by passing the bolts through the longitudinal through holes on the two clamping blocks 111, and the bolts are locked by nuts. Optionally, the bolts are located on the side of the plate 10. By providing a plurality of through holes on the clamping block 111, through holes in appropriate positions can be selected according to the length of the plate 10. As can be understood, the longitudinal fixing hole 101 is a strip-shaped hole extending longitudinally, thereby allowing the longitudinal position of the clamping block 111 to be adjusted. Multiple longitudinal strip-shaped holes are provided transversely, thereby allowing the transverse position of the clamping block 111 to be adjusted. As can be understood, the position of the plate 10 can be adjusted by adjusting the position of the clamping block 111.

[0063] See also Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The clamping assembly 200 includes a support 220, which includes two installation portions 221 spaced apart. A slot for inserting the panel 10 is formed between the two installation portions 221. Each installation portion 221 is provided with a moving block 230. The moving blocks 230 can approach each other and clamp the panel 10. The first wire-passing member 210 is provided on the support 220. In this embodiment, there are five clamping assemblies 200, which are spaced apart and clamped on one side of the top of the panel 10. Optionally, the support 220 is generally a block-shaped structure, and the slot is located at the bottom of the support 220. See Figure 5 and Figure 6 The middle of the moving block 230 has a cavity and an adjusting bolt 240 is passed through the moving block 230. A square nut is passed through the adjusting bolt 240. The adjusting bolt 240 passes through the cavity and the square nut is located in the cavity. The cavity can limit the rotation of the square nut. When the adjusting bolt 240 is rotated, the square nut moves along the length of the adjusting bolt 240, and at the same time pushes the moving block 230 closer to or away from the plate 10. For further information, see Figure 5 and Figure 7A pressure plate 260 is connected to the outside of the mounting portion 221. The pressure plate 260 is used to compress the adjusting bolt 240, limiting its axial movement. Optionally, a compression bolt 270 passes through the pressure plate 260 and into the mounting portion 221. The compression bolt 270 is fitted with a square nut. The compression bolt 270 and the square nut lock the pressure plate 260 and the mounting portion 221, thereby compressing the adjusting bolt 240. Optionally, each mounting portion 221 is connected to two compression bolts 270, one on each side of the adjusting bolt.

[0064] Optionally, a protective pad 250 is provided on the outside of the moving block 230. The provision of the protective pad 250 can protect and buffer the plate 10, prevent the moving block 230 and the plate 10 from hard contact, wear or scratching the plate 10, and at the same time, increase the friction to prevent the clamping assembly 200 from falling off the plate 10. Optionally, the protective pad 250 can be a rubber pad or a silicone pad or other flexible pad. Optionally, the protective pad 250 is annular, and an annular groove is provided on the outer surface of the moving block 230, and the protective pad 250 is partially embedded in the annular groove. Optionally, the protective pad 250 and the moving block 230 are bonded by colloid. Of course, in other embodiments, the protective pad 250 can be square, circular, waist-shaped or other shapes, which are not specifically limited here.

[0065] Furthermore, the first wire-passing member 210 includes a slip ring and a connecting screw that are connected to each other. The support 220 has a cavity, in which a square nut, a first upper washer 280, and a first lower washer 290 are disposed. The first upper washer 280 and the first lower washer 290 are located at the top and bottom of the square nut, respectively. The connecting screw passes through the first upper washer 280 and the square nut and abuts against the first lower washer 290. Tightening the connecting screw presses the square nut against the top of the cavity, and the connecting screw presses the first lower washer 290 against the bottom of the cavity. It is understood that the direction of the slip ring opening can be adjusted by rotating the slip ring, and the direction of the slip ring opening is adjusted according to the way the traction rope 500 passes through.

[0066] Further, see Figure 1 、 Figure 8 and Figure 9, the plate clamping fixture also includes two slide rails 120, the slide rails 120 are connected to the base 100, the sliding assembly 300 includes a sliding base 320, the second wire-passing member 310 is arranged on the sliding base 320, the sliding base 320 is arranged on the slide rails 120 and can drive the second wire-passing member 310 to move along the slide rails 120. In this embodiment, the slide rails 120 extend in the horizontal direction and are connected to the circular fixing holes 103 on the base 100 by bolts and square nuts. It can be understood that since the circular fixing holes 103 are arranged in multiple rows along the longitudinal direction, the longitudinal spacing between the slide rails 120 and the plate 10 is adjustable. In this embodiment, five sets of sliding assemblies 300 are provided on each slide rail 120. See Figure 8 and Figure 9 The slide rail 120 has a slide groove, and a connecting shaft is provided at the bottom of the slide base 320. A bearing 360 is provided on the connecting shaft. The bearing 360 is located in the slide groove and can rotate along the slide rail 120. The bearing 360 cooperates with the slide rail 120 to limit the slide base 320 to have only one horizontal degree of freedom. By adjusting the position of the slide base 320 on the slide rail 120, the position of the second wire member 310 is adjusted, and then the position of the traction rope 500 is adjusted, thereby changing the force condition of the plate 10. Optionally, baffles are provided at the front and rear ends of the slide base 320, and guide grooves that cooperate with the protrusions are provided on the baffles. The baffles guide the slide base 320 to ensure stable movement of the slide base 320.

[0067] Further, see Figure 8 and Figure 9 The sliding assembly 300 further includes a limit block 330 and an adjustment screw 340. A limit slot (not shown) is provided at the bottom of the sliding base 320. The top of the limit block 330 is located in the limit slot, and the bottom of the limit block 330 is located in the slide rail 120. The adjustment screw 340 penetrates the limit slot along a first direction and is threadedly connected to the limit block 330. The first direction is perpendicular to the extension direction of the slide rail 120. The adjustment screw 340 is used to drive the limit block 330 toward or away from the inner wall of the slide rail 120. When the adjustment screw 340 drives the limit block 330 to abut against the inner wall of the slide rail 120, the limit block 330 can prevent the sliding base 320 from moving. Optionally, the inner wall of the slide groove is provided with an arc-shaped protrusion, and one side of the limit block 330 is provided with a recess. When the protrusion and the recess are in close contact, the friction between the limit block 330 and the inner wall of the slide groove can prevent the sliding base 320 from moving. Optionally, the adjusting screw 340 is connected to an adjusting handle 350 , and the adjusting screw 340 is rotated by rotating the adjusting handle 350 , thereby controlling the movement of the limiting block 330 .

[0068] Furthermore, the sliding assembly 300 also includes a sliding platform 370, which is fixedly connected to the sliding base 320, and the second wire-passing member 310 is rotatably connected to the sliding platform 370. Optionally, the second wire-passing member 310 includes a slip ring and a connecting screw that are connected to each other, and the support 220 has a cavity, in which a square nut, a second upper gasket 380 and a second lower gasket 390 are provided. The second upper gasket 380 and the second lower gasket 390 are respectively located at the top and bottom of the square nut. The connecting screw passes through the second upper gasket 380 and the square nut and abuts against the second lower gasket 390. When the connecting screw is tightened, the square nut presses the second upper gasket 380 against the top of the cavity, and the connecting screw presses the second lower gasket 390 against the bottom of the cavity. It can be understood that the direction of the slip ring opening can be adjusted by screwing the slip ring, and the direction of the slip ring opening is adjusted according to the way the traction rope 500 passes through. Optionally, the top of the sliding platform 370 and the second upper gasket 380 are provided with multiple sets of through holes, so that the second wire guide 310 can be passed through the designated through holes according to specific usage needs. Optionally, the sliding platform 370 and the sliding base 320 are connected by bolts. In this embodiment, four bolts are provided connecting the sliding platform 370 and the sliding base 320. In other embodiments, the number of bolts can be two, three, five, or six, etc.

[0069] Further, see Figure 1 、 Figure 10 and Figure 11 , the adjustment assembly 400 also includes a fixed seat 420, a transmission rod 430 and an adjustment base 440. The transmission rod 430 is passed through the adjustment base 440 and is threadedly connected to the adjustment base 440. Both ends of the transmission rod 430 are rotatably connected to the fixed seat 420. The third wire-passing member 410 is arranged on the adjustment base 440. By rotating the transmission rod 430, the adjustment base 440 can drive the third wire-passing member 410 to move back and forth along the transmission rod 430. In this embodiment, the adjustment assembly 400 is located at one end of the locking seat 110 and is fixed by the longitudinal fixing hole 101. Optionally, the fixed seat 420 includes an aluminum profile 421 and a support plate 422 connected to both ends of the aluminum profile 421. The support plate 422 and the aluminum profile 421 are fixedly connected by bolts. Optionally, a square nut is embedded in the bottom of the aluminum profile 421, and the bolt passes through the longitudinal fixing hole 101 and is threadedly connected to the square nut. Transmission rod 430 is pivotally connected to support plate 422 at both ends, with one end extending from support plate 422 and connected to crank handle 460. Crank handle 460 has a sleeve portion that fits over the end of transmission rod 430 and is secured to transmission rod 430 via bolts. When crank handle 460 is cranked, transmission rod 430 and crank handle 460 rotate synchronously, simultaneously causing adjustment base 440 to move along transmission rod 430.

[0070] Optionally, a locking member 470 is provided at one end of the transmission rod 430 that passes through the support plate 422, and the locking member 470 is located between the sleeve portion and the support plate 422. Exemplarily, the locking member 470 includes a clamping block 471, a locking bolt 472, a locking handle 473 and a locking nut 474. The clamping block 471 includes an adjustment portion, and the two adjustment portions are spaced apart to form an adjustment gap. The clamping block 471 has a through hole, and the adjustment gap and the through hole are connected. The locking handle 473 is fixedly sleeved on the locking bolt 472, and the bottom of the locking bolt 472 passes through the adjustment portion and is connected to the locking nut 474. When it is necessary to fix the position of the adjustment base 440, the locking handle 473 is turned to lock the locking bolt 472 and the locking nut 474. At the same time, the adjustment gap is reduced, and the clamping block 471 clamps the transmission rod 430, thereby preventing the screw from rotating.

[0071] Furthermore, the adjustment assembly 400 also includes an adjustment platform 450, which is fixedly connected to the adjustment base 440. The third wire passing member 410 is connected to the adjustment platform 450. Optionally, the adjustment platform 450 is provided with multiple sockets for inserting the third wire passing member 410, and the sockets can be selected in appropriate locations according to usage needs. Optionally, the adjustment platform 450 is fixedly connected to the adjustment base 440 via bolts. Optionally, the third wire passing member 410 includes a slip ring and a connecting screw.

[0072] See also Figure 12 The traction rope 500 includes a first section 510 and a second section 520. The first section 510 is passed through the first and second wire-passing members 210 and 310, and the second section 520 is passed through the third wire-passing member 410. The first end of the first section 510 and the first end of the second section 520 are connected via a first dynamometer 501, and the second end of the first section 510 and the second end of the second section 520 are connected via a second dynamometer 502. The first dynamometer 501 and the second dynamometer 502 are used to measure the tension applied to the traction rope 500. It can be understood that the first section 510, the first dynamometer 501, the second section 520, and the second dynamometer 502 are connected end to end to form a closed loop, so that the tension of the traction rope 500 can be adjusted by adjusting the position of the third wire-passing member 410, and the force balance of various parts of the traction rope 500 can be adjusted by moving the positions of the first and second wire-passing members 210, 310, or other components. Preferably, the traction rope 500 is a steel wire rope, which can withstand high tension while having low friction. The first wire member 210, the second wire member 310, and the third wire member 410 are all made of a material with a low friction coefficient, such as steel, so that the friction between the traction rope 500 and the slip ring can be ignored.

[0073] Continue to see Figure 12, it can be understood that the way the traction rope 500 passes through is related to the number and position of the wire-passing pieces. In this embodiment, there are 5 first wire-passing pieces 210, and each first wire-passing piece 210 is provided with a second wire-passing piece 310 on both sides, and the first wire-passing piece 210 and the second wire-passing pieces 310 on both sides thereof are located on the same straight line (longitudinal direction), the third wire-passing piece 410 and the first wire-passing piece 210 are both located on the same straight line (transverse direction), and the plate surface is located on the central axis of the base 100 and is parallel to the xz plane. When the traction rope 500 passes through in such a way, in the transverse direction, the plate 10 is subjected to equal and opposite forces, so that the resultant force in the transverse direction is zero; in the vertical direction, the plate 10 is subjected to vertical downward pressure. By moving the third wire member 410 closer to the plate 10, the tension on the traction rope 500 can be reduced, thereby reducing the pressure on the plate 10. By moving the third wire member away from the plate 10, the tension on the traction rope 500 can be increased, thereby increasing the pressure on the plate 10.

[0074] This embodiment further provides a panel clamping method based on the above-mentioned panel clamping tool. The panel clamping tool includes a first dynamometer 501 and a second dynamometer 502. The traction rope 500 includes a first section 510 and a second section 520. The panel clamping method includes the following steps:

[0075] S100, fix one end of the plate 10 to the locking seat 110, connect the locking seat 110 to the base 100, connect the clamping assembly 200 to the plate 10, pass the first section 510 through the first wire-passing member 210 and the second wire-passing member 310, pass the second section 520 through the third wire-passing member 410, connect the first end of the first section 510 to the first end of the second section 520 using the first dynamometer 501, and connect the second end of the first section 510 to the second end of the second section 520 using the second dynamometer 502;

[0076] S200, moving the third wire-passing member 410 to adjust the tension on the traction rope 500 so that the readings of the first dynamometer 501 and the second dynamometer 502 are both within a preset range;

[0077] S300, adjust the locking seat 110, the clamping assembly 200, the sliding assembly 300, the adjustment assembly 400 and the traction rope 500;

[0078] S400 , repeat S200 and S300 until the readings of the first dynamometer 501 and the second dynamometer 502 are the same and within a preset range.

[0079] To effectively control vibration and deformation, an appropriate traction rope 500 model is selected through simulation. The preset range should be calculated based on parameters such as the modal frequency of the panel 10 and the characteristics of the traction rope 500. As can be understood, a traction rope 500 with a larger diameter can bear greater loads, but also has greater stiffness and internal stress, resulting in greater friction between the traction rope 500 and the wire guide. Therefore, a traction rope 500 of appropriate thickness is necessary. Simulation can typically determine the required diameter range for the traction rope 500; more precise diameter determination requires experimentation or actual operation. The traction rope 500 model and preset range should be selected so that the natural modes of the traction rope 500 approach those of the panel 10, creating a resonant effect and directing all vibrations during machining to the traction rope 500. Optionally, a broadband vibration absorber can be placed on the traction rope 500 to significantly reduce these vibrations. The selection method for the traction rope 500 and the calculation of the preset range are well-established techniques in the art and will not be elaborated upon here.

[0080] It is understandable that under ideal conditions (the friction between the traction rope 500 and the line-crossing member is zero), the readings on the first dynamometer 501 and the second dynamometer 502 are always the same. However, in actual situations, due to the friction between the traction rope 500 and the line-crossing member, the readings on the first dynamometer 501 and the second dynamometer 502 are prone to deviation. Therefore, after S200, it is necessary to perform S300, that is, to adjust the locking seat 110, the clamping assembly 200, the sliding assembly 300, the adjustment assembly 400 and the traction rope 500 to make the readings of the first dynamometer 501 and the second dynamometer 502 the same. Repeat S200 and S300 until the readings of the first dynamometer 501 and the second dynamometer 502 are the same and within the preset range.

[0081] For example, in S300, the adjustment method at least includes: (1) adjusting the locking seat 110 so that the locking seat 110 clamps the plate 10 to ensure that the plate 10 is on the central axis of the base 100; (2) adjusting the clamping assembly 200, tightening the clamping bolt 270, so that the pressure plate 260 presses the adjusting bolt 240, tightening the adjusting bolt 240, so that the moving block 230 presses the plate 10 to ensure that the plate 10 is on the central axis of the base 100 and is in the vertical plane; (3) adjusting the sliding assembly 300, moving the sliding The base 320 makes the connection direction of the second wire-passing member 310 and the first wire-passing member 210 in the longitudinal direction without offset, thereby ensuring that the resultant force of the plate 10 in the longitudinal direction is zero. After the adjustment is completed, the limit block 330 and the inner side of the slide rail 120 are pressed tightly by rotating the adjustment handle 350 to prevent the sliding component 300 from moving; (4) adjust the adjustment component 400 to align the axis of the transmission rod 430 with the plate 10; (5) adjust the model of the traction rope 500, such as replacing the traction rope 500 with a different diameter.

[0082] After S400 , the plate 10 is processed, and S200 to S400 are repeated, so that the readings of the first dynamometer 501 and the second dynamometer 502 remain the same and within a preset range until the processing is completed.
