Description

Technical Field

[0001] This application relates to the field of machining, and in particular to an anti-shake tooling fixture and machining system. Background Technology

[0002] Tooling fixtures, also known as jigs, are devices used in manufacturing to fix, position, clamp, or support workpieces and semi-finished products. Tooling fixtures play a crucial role in machining, especially in modern manufacturing, with a wide range of applications covering industries from automotive to aerospace. By fixing and positioning workpieces, fixtures not only improve production efficiency but also ensure the accuracy and consistency of the machining process. With technological advancements, fixture design is constantly evolving to adapt to increasingly complex and diverse machining needs. Particularly in four-axis CNC machining, the need to handle workpieces of various shapes and sizes places higher demands on the versatility and stability of fixtures. To meet different machining requirements, fixture design has gradually integrated multiple functions, such as rotation, support, and fixation, to adapt to complex machining environments. Currently, the industry typically adopts the following solutions to meet different machining needs. For example, for machining simple workpieces, fixtures can directly fix the workpiece with simple bolts to achieve simple machining. A further improvement is to equip the fixture with a pressing mechanism, which includes elastic elements and clamping elements. By adjusting the elastic elements, the clamping elements press against the workpiece to achieve fixation. For machining at multiple angles, a rotation mechanism is usually added to the fixture to allow the workpiece to be adjusted at multiple angles during machining. While these solutions meet basic machining needs to a certain extent, they still have certain limitations. As existing workpieces become increasingly diverse, especially for some large workpieces whose bottoms are often uneven, existing fixtures are usually designed specifically for the outline of a workpiece. In addition to clamping elements at both ends, these fixtures also have positioning elements at the bottom for precise placement of the workpiece. After aligning the workpiece with the bottom positioning elements, the user clamps the workpiece using the clamping elements at both ends. However, due to the large weight and volume of these large workpieces, even with both ends fixed during machining, the middle is difficult to secure, causing slight resonance and wobbling. This wobbling intensifies during workpiece rotation, potentially leading to workpiece detachment. This is especially true given the diverse range of large workpieces today, with varying degrees of unevenness at the bottom. Therefore, existing fixture designs face significant challenges in handling large workpieces. Preventing wobbling during machining and achieving stable clamping for a wide variety of large workpieces has become a pressing technical problem. Utility Model Content

[0003] To improve the versatility of fixtures in holding large workpieces, and to ensure the stability of fixtures in holding diverse large workpieces, preventing workpiece shaking or loosening during processing, this application provides an anti-shaking tooling fixture.

[0004] The anti-shake tooling fixture provided in this application adopts the following technical solution:

[0005] An anti-shake tooling fixture includes a support platform for placing a workpiece, a clamping mechanism, and a positioning support mechanism. Both the clamping mechanism and the positioning support mechanism are disposed on the surface of the support platform. The clamping mechanism includes a first clamping component and a second clamping component, both mounted on the surface of the support platform and positioned on opposite sides of the workpiece to clamp it. The positioning support mechanism includes at least one sliding guide rail, a slider, and a positioning support cylinder. A sliding gap is provided between the surface of the support platform and the sliding guide rail. The sliding guide rail is installed within the sliding gap. The slider is slidably mounted on the sliding guide rail. The positioning support cylinder is fixed to the slider. When a workpiece is placed, the slider moves the positioning support cylinder to a position at the bottom of the workpiece for easy support, driving the piston rod of the positioning support cylinder to rise. The piston rod of the positioning support cylinder passes through the sliding gap and abuts against the bottom of the workpiece. By adopting the above technical solution, the clamping mechanism and the positioning support mechanism work together to effectively prevent the workpiece from shaking during processing. Specifically, the first and second clamping components in the clamping mechanism are located on both sides of the workpiece, respectively. By applying clamping forces to both ends of the workpiece, a stable lateral constraint is formed, preventing the workpiece from shifting horizontally. Simultaneously, the combined design of the sliding guide rail, slider, and positioning support cylinder in the positioning support mechanism allows the positioning support cylinder to flexibly adjust its support points according to the specific shape and position of the workpiece's bottom. When the slider moves the positioning support cylinder to the appropriate position on the bottom of the workpiece, the piston rod of the positioning support cylinder rises and abuts against the bottom of the workpiece, thereby providing stable vertical support for the workpiece. This multi-point support method not only effectively reduces resonance caused by the workpiece's own weight or processing vibrations but also adapts to workpieces of different shapes and sizes. Especially for large workpieces with uneven bottoms, it can flexibly adjust to a positioning position that facilitates contact with the bottom of the workpiece, significantly improving clamping stability and avoiding the risk of workpiece loosening during processing. Preferably, the sliding guide rail is laterally positioned on the support table surface. By adopting the above technical solution, the sliding guide rail is laterally positioned on the support table surface, allowing the slider to move along the width direction of the workpiece. This design allows for flexible adjustment of the positioning support cylinder's position based on the specific shape and force requirements of the workpiece's bottom, ensuring accurate access to key support points. When the workpiece is placed on the support platform, the slider moves the positioning support cylinder to the optimal support position, subsequently driving the cylinder's piston rod to rise, bringing it into contact with the workpiece's bottom and providing stable support. The transverse arrangement of the sliding guide effectively prevents workpiece swaying along its length, and the clamping mechanism further enhances the overall stability of the workpiece by fixing both ends.This layout not only improves the adaptability of the fixture but also significantly reduces resonance caused by insufficient central support during workpiece processing, thus ensuring processing accuracy and safety. Preferably, the sliding guide rail is longitudinally positioned on the support table surface. By adopting the above technical solution, the longitudinal positioning of the sliding guide rail on the support table surface allows the slider to flexibly adjust its position along the length of the workpiece. This design fully considers the uneven bottom of large workpieces and can accurately locate support points according to the actual shape and size of the workpiece. When the slider moves to the position where support is needed at the bottom of the workpiece, the piston rod of the positioning support cylinder rises and abuts against the bottom of the workpiece, thereby providing stable support force. Because the sliding guide rail is arranged longitudinally, the selection of support points is more flexible, especially suitable for large workpieces with long or irregular shapes, effectively preventing the workpiece from wobbling during processing due to lack of central support. Furthermore, the longitudinally positioned sliding guide rail works synergistically with the clamping mechanism, further enhancing the overall stability of the workpiece and ensuring the safety and accuracy of the processing. Preferably, the number of sliding guide rails is greater than or equal to two, and the sliding guide rails are staggered on the support table surface. By adopting the above technical solution, the number of sliding guide rails is set to be greater than or equal to two, and they are staggered on the support table surface. This design allows the sliding guide rails to cover multiple key areas on the bottom of the workpiece, thereby ensuring that the positioning support mechanism can flexibly adjust its position according to the actual shape and size of the workpiece. When the workpiece is placed on the support table, the slider can move on the staggered sliding guide rails, driving the positioning support cylinder to the optimal position where the bottom of the workpiece needs support. Due to the staggered distribution of the sliding guide rails, a suitable support point can always be found regardless of the unevenness of the bottom of the workpiece, effectively preventing the workpiece from shaking due to uneven force during processing. In addition, the staggered layout of multiple sliding guide rails also improves the adaptability of the positioning support mechanism, meeting the clamping requirements of workpieces of different shapes and sizes, thereby significantly improving the stability and versatility of the tooling fixture. Preferably, each of the sliding guide rails is interconnected. By adopting the above technical solution, the interconnected design between the sliding guide rails allows the slider to move freely on multiple sliding guide rails, thereby expanding the adjustable range of the positioning support cylinder. This design can not only adapt to the bottom support requirements of workpieces of different shapes and sizes, but also flexibly adjust to the optimal support position when the workpiece is placed. Once the slider moves the positioning support cylinder to a suitable position at the bottom of the workpiece, it drives the piston rod of the positioning support cylinder to rise, causing the piston rod to abut against the bottom of the workpiece, forming a stable support point. Because the sliding guides are interconnected, the slider is not limited to a single track and can more accurately find and support the area of ​​most significant workpiece movement, effectively reducing resonance and shaking during machining and improving machining stability and accuracy. Furthermore, this design enhances the versatility of the fixture, enabling it to adapt to a wider variety of large workpieces and meet diverse machining needs.Preferably, the sliding gap is in the range of 3cm-5cm. By adopting the above technical solution, setting the sliding gap to a range of 3cm-5cm ensures sufficient structural strength between the sliding guide rail and the support table surface, while also ensuring smooth movement of the slider on the sliding guide rail. If the gap is too small, the slider may experience excessive frictional resistance during movement, affecting the precise adjustment of the positioning support cylinder; while if the gap is too large, it will weaken the overall stability of the support table and fail to effectively support large workpieces. Therefore, limiting the sliding gap to the range of 3cm-5cm ensures structural strength and stability while also meeting the need for flexible slider movement, thereby achieving precise positioning and reliable support of the bottom of the workpiece and effectively preventing the workpiece from shaking during processing. Preferably, the piston rod of the positioning support cylinder is provided with an anti-slip pad at its end. By adopting the above technical solution, providing an anti-slip pad at the end of the piston rod of the positioning support cylinder can significantly improve stability during workpiece clamping. Specifically, when the piston rod of the positioning support cylinder rises and abuts against the bottom of the workpiece, the anti-slip pad increases the friction between the end of the piston rod and the bottom of the workpiece, effectively preventing the workpiece from sliding due to vibration or rotation during processing. Furthermore, the anti-slip pad also disperses the pressure of the piston rod end on the bottom of the workpiece, preventing damage to the workpiece surface due to excessive local pressure. This design not only improves the workpiece's fixation during processing but also adapts to workpiece bottoms of different shapes and materials, further enhancing the versatility and reliability of the fixture. Preferably, the first clamping assembly includes a first clamping block and a first clamping cylinder. The first clamping cylinder is disposed on the platform of the support table, and its piston rod is fixedly connected to the first clamping block. The first clamping cylinder drives the first clamping block to rise and fall, and the first clamping block presses down to clamp the workpiece. By adopting the above technical solution, the first clamping cylinder is disposed on the platform of the support table, and its piston rod is fixedly connected to the first clamping block. When it is necessary to clamp the workpiece, the first clamping cylinder drives the piston rod to extend or retract, thereby driving the first clamping block to achieve a rising and falling action. The raising and lowering of the first clamping block allows for precise adjustment of its relative position to the workpiece, ensuring sufficient pressure is applied during clamping to firmly secure the workpiece. This design not only improves clamping stability but also prevents workpiece wobbling due to insufficient clamping force. Furthermore, through precise control of the first clamping cylinder, the clamping force can be flexibly adjusted according to the thickness and shape of different workpieces, effectively preventing workpiece displacement or loosening during processing, thereby significantly improving processing accuracy and efficiency.Preferably, the second clamping assembly includes a second clamping block, a connecting rod, a support, a lifting block, and a second clamping cylinder. The support is fixed to the table surface of the support platform, the lifting block slides with the support, the second clamping cylinder is disposed on the table surface of the support platform, and the piston rod of the second clamping cylinder is fixedly connected to the lifting block. The second clamping cylinder is used to drive the lifting block to move up and down. One end of the second clamping cylinder is rotatably connected to the lifting block, one end of the connecting rod is rotatably connected to the support, and the other end of the connecting rod is rotatably connected to the second clamping block. By adopting the above technical solution, the second clamping assembly can achieve precise clamping of the workpiece. Specifically, the support is fixed to the table surface of the support platform, providing a stable installation foundation for the entire clamping structure. The sliding fit design between the lifting block and the support allows the lifting block to move flexibly in the vertical direction, thereby adapting to the needs of workpieces of different heights. The second clamping cylinder is disposed on the table surface of the support platform, and its piston rod is fixedly connected to the lifting block. By driving the piston rod to extend and retract, the lifting action of the lifting block can be precisely controlled. Meanwhile, one end of the second clamping cylinder is rotatably connected to the lifting block, ensuring a smoother and more reliable force transmission. One end of the connecting rod is rotatably connected to the support, and the other end is rotatably connected to the second clamping block, forming a lever structure. When the lifting block moves up and down, the connecting rod's transmission action drives the second clamping block to produce a corresponding displacement, thereby achieving effective clamping of the workpiece. This design not only improves the stability of clamping but also enhances the fixture's adaptability to different types of workpieces. Preferably, both the first and second clamping blocks have a locking portion extending from the end closest to the workpiece. The locking portion is an arc-shaped transition surface that abuts against the workpiece. By adopting the above technical solution, the first and second clamping blocks have locking portions with arc-shaped transition surfaces extending from the end closest to the workpiece. This design increases the contact area between the clamping block and the workpiece, and the arc-shaped transition surface can better adapt to the contour of the workpiece surface, thereby effectively dispersing pressure during clamping and avoiding damage to the workpiece surface due to excessive local pressure. Furthermore, because the curved transition surface fits more closely to the workpiece surface, the clamping stability is significantly improved under clamping force, reducing workpiece wobbling during processing. This structure not only enhances clamping reliability but also further strengthens adaptability to workpieces of various shapes, making it particularly suitable for large workpieces with uneven bottoms, ensuring their stability and safety during processing.

[0006] In summary, this application includes at least one of the following beneficial technical effects:

[0007] 1. By combining a clamping mechanism and a positioning support mechanism, the clamping mechanism provides stable clamping force from both ends of the workpiece, while the slider and positioning support cylinder in the positioning support mechanism provide flexible and reliable support for the middle of the workpiece. This design effectively solves the problem of insufficient middle support caused by existing fixtures relying solely on fixing at both ends, thus preventing the workpiece from shaking due to resonance during processing, and is especially suitable for large workpieces with uneven bottoms;

[0008] 2. In the design of the positioning support mechanism, after the slider moves along the sliding guide rail to a suitable position at the bottom of the workpiece, the piston rod of the positioning support cylinder extends and abuts against the bottom of the workpiece. Since the position of the slider can be flexibly adjusted according to the specific shape and size of the workpiece, the piston rod can be ensured to be in close contact with the bottom of the workpiece regardless of the unevenness of the bottom of the workpiece, thereby improving the adaptability of the fixture to different types of large workpieces;

[0009] 3. The first clamping assembly drives the first clamping block to press down on the workpiece via the first clamping cylinder, while the second clamping assembly clamps the workpiece on the other side via a linkage mechanism and a second clamping cylinder. This dual-sided clamping method, combined with the positioning support mechanism, forms an overall stable constraint on the workpiece, which not only significantly enhances the stability of the workpiece during processing but also effectively avoids the risk of loosening due to insufficient or uneven clamping force.

[0013] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0014] This application provides an anti-shake tooling fixture, referring to... Figure 1It consists of a support platform 1, a clamping mechanism 2, and a positioning support mechanism 3. Both the clamping mechanism 2 and the positioning support mechanism 3 are mounted on the surface of the support platform 1. When the workpiece is placed on the surface of the support platform 1, the clamping mechanism 2 presses down on the workpiece to clamp it, and the positioning support mechanism 3 is slidably mounted on the bottom of the workpiece and abuts against the bottom of the workpiece to accurately position and support the workpiece.

[0015] Specifically, the clamping mechanism 2 includes a first clamping component 21 and a second clamping component 22. In this embodiment, there is one first clamping component 21 and two second clamping components 22. Both second clamping components 22 are located on one side of the workpiece, and the first clamping component 21 is located on the other side of the workpiece, forming a triangular balance structure with three-point positioning.

[0016] The first clamping assembly 21 includes a first clamping block 211 and a first clamping cylinder 212. The first clamping cylinder 212 is mounted on the platform of the support table 1, and its piston rod is fixedly connected to the first clamping block 211, used to drive the first clamping block 211 to rise and fall, thereby achieving downward clamping of the workpiece. The first clamping block 211 can be made of aluminum alloy or stainless steel, which has high strength and wear resistance. In order to improve the clamping effect, a clamping part a is provided at the end of the first clamping block 211 near the workpiece. The clamping part a is an arc-shaped transition surface, which can better fit the workpiece surface and reduce stress concentration during clamping.

[0017] Furthermore, the second clamping assembly 22 includes a second clamping block 221, a connecting rod 222, a support 223, a lifting block 224, and a second clamping cylinder 225. The support 223 is fixed to the surface of the support platform 1. The lifting block 224 is slidably engaged with the support 223. The piston rod of the second clamping cylinder 225 is fixedly connected to the lifting block 224 to drive the lifting block 224 to rise and fall. One end of the connecting rod 222 is rotatably connected to the lifting block 224, and the other end is rotatably connected to the second clamping block 221. Through the transmission action of the connecting rod 222, the precise movement of the second clamping block 221 is achieved. The second clamping block 221 is also provided with a locking part a, which ensures the clamping effect while also improving the stability of the workpiece.

[0018] Specifically, the positioning support mechanism 3 includes a sliding guide rail 31, a slider 32, and a positioning support cylinder 33. The support platform 1 has a sliding gap 11 corresponding to the sliding guide rail 31. The sliding guide rail 31 is installed within the sliding gap 11, and the slider 32 is slidably installed on the sliding guide rail 31. The positioning support cylinder 33 is fixed to the slider 32. When a workpiece is placed, the slider 32 moves the positioning support cylinder 33 to a position at the bottom of the workpiece that facilitates support, driving the piston rod of the positioning support cylinder 33 to rise, causing the piston rod to pass through the sliding gap 11 and abut against the bottom of the workpiece.

[0019] The sliding guide rails 31 can be arranged horizontally or vertically on the surface of the support platform 1, or they can be staggered to increase the number of support points. In this embodiment, the number of sliding guide rails 31 is greater than or equal to two, and they are staggered on the surface of the support platform 1. Each sliding guide rail 31 is connected, allowing the slider 32 to move flexibly in multiple directions, further increasing the number and distribution range of support points. This design is particularly suitable for large workpieces with uneven bottoms, and can adjust the support position according to the specific shape of the workpiece to ensure the stability of the workpiece during processing.

[0020] Furthermore, an anti-slip pad is provided at the end of the piston rod of the positioning support cylinder 33. The anti-slip pad can be made of rubber or silicone, which has good anti-slip performance and can also act as a buffer to reduce damage to the workpiece surface. This design not only improves the stability of the workpiece but also extends the service life of the fixture. In particular, the spacing of the sliding gap 11 is in the range of 3cm-5cm, and this embodiment preferably has a spacing of 3cm, which can ensure the smooth movement of the slider 32 and avoid interference during workpiece processing. The implementation principle of this embodiment is as follows: the fixture consists of a support platform 1, a clamping mechanism 2, and a positioning support mechanism 3. Both the clamping mechanism 2 and the positioning support mechanism 3 are installed on the table surface of the support platform 1. The clamping mechanism 2, through the synergistic action of the first clamping component 21 and the second clamping component 22, forms a triangular balance structure with three-point positioning to ensure that the workpiece is firmly clamped. The first clamping assembly 21 uses a first clamping cylinder 212 to drive the first clamping block 211 to press down and clamp, while the second clamping assembly 22 uses a connecting rod 222 to achieve precise movement of the second clamping block 221. Both are equipped with a locking part a with an arc-shaped transition surface to improve the clamping effect. The positioning support mechanism 3, through the cooperation of the sliding guide rail 31, the slider 32, and the positioning support cylinder 33, realizes the function of flexibly adjusting the support position according to the shape of the bottom of the workpiece, which is particularly suitable for large workpieces with uneven bottoms. The staggered arrangement and interconnected design of the sliding guide rail 31 further increases the number and distribution range of support points, improving the flexibility of the positioning support function and the stability of the workpiece. In addition, the anti-slip pad design at the end of the piston rod of the positioning support cylinder 33 is both anti-slip and buffering, reducing damage to the workpiece surface and extending the service life of the fixture. The reasonable spacing of the sliding gap 11 ensures the smooth movement of the slider 32 and avoids interference during workpiece processing. This series of design derivations together achieve the high stability and applicability of the anti-shaking tooling fixture.

[0021] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
