Description

Technical Field

[0001] This invention relates to the field of fixture technology, specifically a clamping fixture and method for easily deformable parts. Background Technology

[0002] In the process of assembling printed circuit boards (PCBs), a large number of parts are easily deformable, including thin connectors, flexible circuit boards (FPCs), thin-walled shields, and ultra-thin metal brackets. These parts are characterized by thin walls, poor rigidity, and large dimensional deviations. They are very easy to deform during clamping and processing, which directly affects the assembly accuracy and product qualification rate.

[0003] As electronic products become thinner and lighter, and with higher density, the proportion of easily deformable parts in PCB assembly continues to rise. Traditional clamping solutions are no longer sufficient to meet production requirements, and there is an urgent need to develop a clamping fixture that can effectively prevent parts from deforming during clamping and processing. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping fixture and method for easily deformable parts, so as to solve the problem of deformation of easily deformable parts during the clamping and fixing process in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping fixture for easily deformable parts, comprising an adaptive bearing mechanism and a control system, wherein the adaptive bearing mechanism comprises an adaptive bearing component and an equidistant module; The adaptive load-bearing component includes a fixed load-bearing component and a movable load-bearing component. The fixed load-bearing component and the movable load-bearing component have the same structure. The movable load-bearing component is slidably connected to the equidistant module. The fixed bearing assembly includes a mounting block and a floating bearing element. The mounting block is fixedly connected to the equidistant module. The mounting block has several receiving slots. The floating bearing element is installed in the receiving slots. Both the floating bearing element and the equidistant module are electrically connected to the control system. Before clamping, the control system drives the equidistant module to operate. The equidistant module causes the movable bearing component to slide symmetrically relative to the fixed bearing component, so that the size and spacing of the adaptive bearing mechanism matches the contour of the current part. After the size and spacing are adjusted, the control system controls the floating bearing element on the fixed bearing component and the movable bearing component to operate. The output end of the floating bearing element extends outward to reach the preset working position, and the easily deformable part is placed on the adaptive bearing mechanism. The floating bearing element fits and supports the bottom of the part, completing the contour support. After the adaptive bearing mechanism fully stabilizes the part, the elastic pressing mechanism on the operating base operates to press the edge of the part from above, realizing coordinated clamping from top to bottom without damage.

[0006] The floating load-bearing element includes a hydraulic element, a flexible pressure-bearing head, a universal ball joint, an elastic component, and a bellows. The hydraulic element is mounted on the mounting block, and the output end of the hydraulic element is provided with an elastic component. The elastic component is hinged to the universal ball joint, and the end of the universal ball joint away from the elastic component is connected to the flexible pressure-bearing head. The bellows is connected to the hydraulic element, and the hydraulic element is electrically connected to the control system. The hydraulic element is a hydraulic cylinder. Before clamping, the hydraulic component is activated by manual operation of the control system. Its output end pushes the elastic component upward to reach the preset working position. After that, the hydraulic component stops operating, and the easily deformable part is placed on the floating bearing component. When the top flexible bearing head contacts the bottom of the easily deformable part, if there is a slight tilt on the bottom surface of the part, the universal ball head will deflect, so that the flexible bearing head automatically adjusts its angle to achieve complete contact with the bottom surface of the part. At this time, the elastic component is subjected to the pressure of the part and slides slightly, ensuring that the easily deformable part will not deform due to rigid contact. During the extension and retraction of the hydraulic component, the bellows connected to it is stretched or compressed accordingly, which plays a role in strictly preventing dust and protecting the internal structure, and preventing chips or debris from falling into the hydraulic component.

[0007] The elastic component includes a floating sleeve, a return spring, and a floating rod. The floating sleeve is located at the output end of the hydraulic element. A floating cavity is formed inside the floating sleeve. One end of the return spring is fixedly connected to the bottom of the floating cavity, and the other end of the return spring is fixedly connected to the floating rod. The floating rod is slidably sleeved inside the floating sleeve, and one end of the floating rod extending out of the floating sleeve is hinged to a universal ball joint. When the flexible bearing head contacts the easily deformable part, the floating rod slides slightly within the floating sleeve, and the return spring undergoes elastic deformation, providing a slight elastic buffer to prevent rigid contact from causing local deformation of the part. When the upper elastic pressing mechanism then starts working and presses the part down, the part moves slightly downward under pressure. This downward pressure is transmitted to the floating rod through the universal ball joint, causing the return spring to be further compressed, absorbing the clamping stress difference and maintaining a stable supporting force. When the clamping work is completed, the upper pressing mechanism releases, the return spring releases energy, and pushes the floating rod to return to its original position.

[0008] It also includes an elastic pressing mechanism, which is symmetrically installed on both sides of the adaptive bearing mechanism. Before clamping, the elastic pressing mechanism is manually adjusted to be in a raised state to prevent it from obstructing the alignment of the part when it is placed. After the part is placed and initially positioned, the elastic pressing mechanism is driven to fall, so that the elastic pressing end presses against the edge area of ​​the part, applying a uniform pre-compression force to the part. This, together with the support force of the adaptive bearing mechanism below, completes the stable clamping of the part.

[0009] The elastic pressing mechanism includes a bracket, an elastic clamping member, and a pressing component. The bracket has a moving groove, the elastic clamping member is slidably disposed on the moving groove, and the pressing component is connected to the elastic clamping member. After the adaptive bearing mechanism completes the bearing of the part, the elastic clamping member is manually driven to slide along the moving groove on the bracket to adjust and align the pressing component with the optimal pressing point above the part. After adjustment, the pressing component is operated to move downward through the elastic structure inside the elastic clamping member, applying a downward clamping force to the part, so that the part is firmly fixed on the stabilized adaptive bearing mechanism.

[0010] The elastic clamping component includes a telescopic rod and a clamping seat. The clamping seat is slidably disposed on the moving groove. An elastic element is disposed inside the clamping seat. One end of the telescopic rod is connected to the elastic element. The telescopic rod can slide along the axial direction of the clamping seat. The pressing component is disposed on the clamping seat. When a part is placed on the adaptive bearing mechanism, the edge of the part will contact the elastic clamping component. Since multiple telescopic rods are disposed on the clamping seat, they can adapt to the edge contours of different parts. Each telescopic rod can extend and retract independently according to the height of the part at the contact position. The elastic force of the elastic element adaptively offsets the height difference of the part edge, ensuring that the pressing component can stably press against the surface of the part.

[0011] The pressing component includes a pressing base, a handle, and a pressing rod. The pressing base is mounted on a clamping seat, and the handle and pressing rod are connected. Both the handle and the pressing rod are rotatably connected to the pressing base. When placing a part and when the adaptive bearing mechanism performs contour bearing, the handle is in a raised state, driving the connected pressing rod to rotate and lift around the pressing base, making room for the part. After the adaptive bearing mechanism completes its bearing, the handle is manually rotated downwards, causing the pressing rod to rotate synchronously around the pressing base and press downwards. The pressing rod presses against the surface of the part. The clamping force can be adjusted according to the size and thickness of different parts to ensure that the part remains in a stable clamped state without displacement.

[0012] A clamping method for easily deformable parts, the method comprising the following specific steps: S1. The parts are placed manually on the adaptive load-bearing mechanism; S2. The adaptive load-bearing mechanism floats and rotates according to the size and shape of the part, automatically adjusting to fit the part. S3. The workpiece is pressed and fixed by manually operating the elastic pressing mechanism.

[0013] Step S2 includes the following specific steps: S201. Start the equidistant module and move the load-bearing components symmetrically to match the spacing of the adaptive load-bearing mechanism with the contour of the part. S202. Start the hydraulic component, and its output end will push the elastic component to move upward, so that the flexible pressure head reaches the preset working position. S203. Place the part on the floating bearing element, and the flexible bearing head contacts the bottom of the part and automatically adjusts the angle through the universal ball head; S204. The elastic component slides slightly under pressure, providing non-destructive support to the bottom of easily deformable parts.

[0014] Step S3 includes the following specific steps: S301, Manual sliding elastic clamping component, along the moving groove of the bracket, aligns the pressing component with the optimal pressing point above the part; S302. Multiple telescopic rods on the clamping seat extend and retract independently, and elastic elements adaptively offset the height difference at the edge of the part. S303: Manually hold the handle and rotate it downwards, causing the pressure rod to rotate synchronously around the pressure seat and press down against the surface of the part; S034. Adjust the clamping force according to the thickness of the part to ensure that the part is firmly and without deformation fixed on the bearing mechanism.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves stress-free and stable bearing for various complex and unevenly thick easily deformable parts through the cooperation of equidistant modules and floating bearing elements. During operation, the equidistant modules drive the moving bearing components to slide symmetrically to accurately match the contour of the parts. When the flexible bearing head contacts the bottom of the part, if there is a slight tilt on the surface, the universal ball head can deflect in multiple dimensions to achieve a perfect fit. Combined with the elastic extension and slight sliding of the return spring, the risk of local stress concentration and warping deformation caused by traditional rigid support is eliminated, effectively improving the stability when clamping easily deformable parts and the overall qualification rate of the parts.

[0016] 2. This invention achieves adaptive flexible clamping and fixing of easily deformable parts by the cooperation of elastic clamping components and pressing components. The pressing components are aligned with the optimal clamping point by sliding the elastic clamping components. Multiple telescopic rods in the clamping seat can extend and retract independently according to the height difference of the parts' edges to adapt to parts with different contours. The pressing components can adjust the clamping force according to different parts sizes to prevent processing displacement, while avoiding damage to parts caused by rigid clamping.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Specific implementation examples: such as Figures 1-9As shown, the present invention provides a technical solution: a clamping fixture for easily deformable parts, comprising a base 1, an adaptive bearing mechanism 2, an elastic pressing mechanism 3, and a control system. The elastic pressing mechanism 3 is disposed on the base 1. The adaptive bearing mechanism 2 includes an adaptive bearing component 21 and an equidistant module 20. The adaptive bearing component 21 includes a fixed bearing component 22 and a movable bearing component 23. The fixed bearing component 22 and the movable bearing component 23 have the same structure. The movable bearing component 23 is slidably connected to the equidistant module 20. The equidistant module 20 is electrically connected to the control system. Before clamping, the elastic pressing mechanism 3 is manually adjusted to be in a raised state. The control system is then operated to drive the equidistant module 20 to run. The equidistant module 20 causes the movable bearing component 23 to slide symmetrically relative to the fixed bearing component 22, so that the size and spacing of the adaptive bearing mechanism 2 matches the contour of the current part.

[0021] The fixed bearing component 22 includes a mounting block 221, which is fixedly connected to the equidistant module 20. The mounting block 221 is provided with a plurality of floating bearing elements 222. The floating bearing elements 222 include a hydraulic element 223, a flexible pressure head 224, a universal ball head 225, an elastic component 226, and a bellows 227. The hydraulic element 223 is provided on the mounting block 221. The output end of the hydraulic element 223 is provided with an elastic component 226. The elastic component 226 is hinged to the universal ball head 225. The end of the universal ball head 225 away from the elastic component 226 is connected to the flexible pressure head 224. The bellows 227 is connected to the hydraulic element 223. The hydraulic element 220 is electrically connected to the control system. Hydraulic component 223 is a hydraulic cylinder. Before clamping, the hydraulic component 223 is started by manual operation control system. Its output end pushes the elastic component 226 upward. After reaching the preset working position, the hydraulic component 223 stops running and the easily deformable part is placed on the floating bearing component 222. When the top flexible bearing head 224 contacts the bottom of the easily deformable part, if there is a slight tilt on the bottom surface of the part, the universal ball head 225 will deflect, so that the flexible bearing head 224 automatically adjusts the angle and achieves complete contact with the bottom surface of the part. At this time, the elastic component 226 is subjected to the pressure of the part and slides slightly, ensuring that the easily deformable part will not be deformed due to rigid contact. During the extension and retraction of the hydraulic component 223, the bellows 227 connected to it is stretched or compressed accordingly, which plays a role in strictly preventing dust and protecting the internal structure, and preventing chips or debris from falling into the hydraulic component 223.

[0022] The elastic component 226 includes a floating sleeve 2261, a return spring 2262, and a floating rod 2263. The floating sleeve 2261 is located at the output end of the hydraulic component 223. A floating cavity is formed inside the floating sleeve 2261. One end of the return spring 2262 is fixedly connected to the bottom of the floating cavity, and the other end of the return spring 2262 is fixedly connected to the floating rod 2263. The floating rod 2263 is slidably sleeved inside the floating sleeve 2261. One end of the floating rod 2263 extending out of the floating sleeve 2261 is hinged to the universal ball joint 225. When the flexible pressure head 224 contacts the easily deformable part... The floating rod 2263 slides slightly within the floating sleeve 2261, causing the return spring 2262 to undergo elastic deformation, providing a small elastic buffer to prevent rigid contact from causing local deformation of the part. When the upper elastic pressing mechanism 3 then starts working and presses the part down, the part moves slightly downward under pressure. This downward pressure is transmitted to the floating rod 2263 through the universal ball joint 225, causing the return spring 2262 to be further compressed, absorbing the clamping stress difference and maintaining a stable supporting force. When the clamping work is completed, the upper pressing mechanism is released, the return spring 2262 releases energy, and pushes the floating rod 2263 to return to its original position.

[0023] The elastic pressing mechanism 3 includes a bracket 31, an elastic clamping member 32, and a pressing component 33. The bracket 31 has a moving groove 311. The elastic clamping member 32 includes a telescopic rod 321 and a clamping seat 322. The clamping seat 322 is slidably disposed on the moving groove 311. An elastic member is disposed inside the clamping seat 322. One end of the telescopic rod 321 is connected to the elastic member. The telescopic rod 321 can slide along the axial direction of the clamping seat 322. The pressing component 33 is disposed on the clamping seat 322. When a part is placed on the adaptive bearing mechanism 2, the edge of the part will contact the elastic clamping member 32. Since multiple telescopic rods 321 are disposed on the clamping seat 322, they can adapt to the edge contours of different parts. Each telescopic rod 321 can extend and retract independently according to the height of the part at the contact position. The elastic force of the elastic member adaptively offsets the height difference of the part edge, ensuring that the pressing component 33 can stably press against the surface of the part.

[0024] The pressing component 33 includes a pressing base 331, a handle 332, and a pressing rod 333. The pressing base 331 is mounted on the clamping base 322. The handle 332 and the pressing rod 333 are connected and rotatably connected to the pressing base 331. When placing the part and when the adaptive bearing mechanism 2 performs contour bearing, the handle 332 is in a raised state, which drives the connected pressing rod 333 to rotate and lift around the pressing base 331, making room for the placement of the part. After the adaptive bearing mechanism 2 completes the bearing, the handle 332 is manually held and rotated downwards. The handle 332 drives the pressing rod 333 to rotate synchronously around the pressing base 331 and press downwards. The pressing rod 333 presses against the surface of the part. The clamping force can be adjusted according to the size and thickness of different parts to ensure that the parts remain in a stable clamped state and do not shift.

[0025] A clamping method for easily deformable parts, the method comprising the following specific steps: S1. The parts are placed manually on the adaptive load-bearing mechanism; S2. The adaptive load-bearing mechanism floats and rotates according to the size and shape of the part, automatically adjusting to fit the part. S3. The workpiece is pressed and fixed by manually operating the elastic pressing mechanism.

[0026] Step S2 includes the following specific steps: S201. Start the equidistant module and move the load-bearing components symmetrically to match the spacing of the adaptive load-bearing mechanism with the contour of the part. S202. Start the hydraulic component, and its output end will push the elastic component to move upward, so that the flexible pressure head reaches the preset working position. S203. Place the part on the floating bearing element, and the flexible bearing head contacts the bottom of the part and automatically adjusts the angle through the universal ball head; S204. The elastic component slides slightly under pressure, providing non-destructive support to the bottom of easily deformable parts.

[0027] Step S3 includes the following specific steps: S301, Manual sliding elastic clamping component, along the moving groove of the bracket, aligns the pressing component with the optimal pressing point above the part; S302. Multiple telescopic rods on the clamping seat extend and retract independently, and elastic elements adaptively offset the height difference at the edge of the part. S303: Manually hold the handle and rotate it downwards, causing the pressure rod to rotate synchronously around the pressure seat and press down against the surface of the part; S034. Adjust the clamping force according to the thickness of the part to ensure that the part is firmly and without deformation fixed on the bearing mechanism.

[0028] Working principle of the invention: Before clamping, the elastic pressing mechanism 3 is manually adjusted to keep it in the raised and released state, thereby making room for the placement of the part. The equidistant module 20 in the adaptive bearing mechanism 2 is driven to run by the manual operation control system. The equidistant module 20 drives the moving bearing component 23 to slide symmetrically relative to the fixed bearing component 22, so that the overall size spacing of the adaptive bearing mechanism 2 matches the contour of the part to be processed.

[0029] After the size spacing is adjusted to the correct position, the control system controls the floating load element 222 on the fixed load component 22 and the moving load component 23 to operate. The hydraulic element 223 is activated, and its output end pushes the elastic component 226 to move upward. After reaching the preset working position, it stops operating. During the extension and retraction of the hydraulic element 223, the bellows 227 connected to it is stretched or compressed accordingly, which plays a role in strictly preventing dust and protecting the internal structure, preventing chips or debris from falling into the hydraulic element 223.

[0030] The easily deformable part is placed smoothly on the adaptive bearing mechanism 2, so that it falls above the floating bearing element 222. When the flexible bearing head 224 at the top contacts the bottom of the easily deformable part, if there is a slight tilt on the bottom surface of the part, the universal ball head 225 will deflect, so that the flexible bearing head 224 automatically adjusts the angle and achieves complete contact with the bottom surface of the part.

[0031] While the flexible pressure head 224 contacts the part, the internal floating rod 2263 slides slightly within the floating sleeve 2261, and the internal return spring 2262 undergoes elastic deformation, providing a small elastic buffer to ensure that the easily deformable part will not undergo local deformation due to rigid contact.

[0032] After the adaptive bearing mechanism 2 fully stabilizes the part, the elastic clamping member 32 is manually slid along the moving groove 311 on the bracket 31 to adjust and align the pressing member 33 to the optimal pressing point above the part. During this process, the edge of the part will come into contact with the elastic clamping member 32. Since the clamping seat 322 is provided with multiple telescopic rods 321, it can adapt to the edge contours of different parts. Each telescopic rod 321 can extend and retract independently according to the height of the part at the contact position, and the elastic force of the internal elastic member adaptively offsets the height difference of the part edge.

[0033] After adjustment, manually hold the handle 332 and rotate it downwards. The handle 332 drives the pressure rod 333 to rotate synchronously around the pressure seat 331 and press downwards. The pressure rod 333 presses against the surface of the part. The operator can flexibly adjust the clamping force according to the size and thickness of different parts.

[0034] At this time, the part is compressed and falls slightly. This downward pressure is transmitted to the floating rod 2263 through the universal ball joint 225, which further compresses the return spring 2262, absorbs the clamping stress difference, and maintains a stable supporting force.

[0035] After the work is completed, manually lift the handle 332 upwards to release the upper pressing mechanism and relieve the pressure on the upper surface of the part. At the same time, as the hydraulic component 223 is depressurized, the return spring 2262 releases energy and pushes the floating rod 2263 back to the initial position, so that the processed part can be taken out and one work cycle is completed.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
