Anti-deformation thin part line cutting contour tooling

Abstract

This utility model discloses a tooling for wire cutting the outline of thin parts to prevent deformation, specifically a tooling for wire cutting thin parts. It includes a base and a first support. A tooling table is fixedly installed on the top of the base. Two transverse sliding grooves are provided on the tooling table. Slider blocks are slidably arranged in opposite directions within the grooves of each sliding groove. A mounting plate is fixedly installed at the top of each slider. A clamping mechanism for holding the side of the part is installed on the side wall of the mounting plate. This utility model allows for the initial adjustment of the clamping plates to the appropriate position for thin parts of the same batch and specifications using the threaded rod and the first knob in the clamping mechanism. Subsequent clamping or disassembly does not require repeated adjustment of individual clamping plates. Instead, the sliding plate is driven by the locking mechanism, which in turn drives all sliders to slide synchronously in opposite directions within the sliding grooves via the linkage rod. This achieves synchronous adjustment of the spacing between all clamping plates, significantly reducing repetitive operations and quickly completing the clamping and disassembly of parts.

Description

Technical Field

[0001] This utility model relates to the field of parts processing auxiliary tools, specifically a wire cutting tooling for preventing deformation of thin parts. Background Technology

[0002] In the prior art, thin parts in the same batch usually refer to thin components with consistent specifications (size, thickness, etc.) (such as mass-produced thin sheet metal parts, thin substrates in electronic devices, etc.). These parts need to be clamped and disassembled during processing, and there are certain requirements for clamping efficiency.

[0003] For the same batch of parts, each clamping component needs to be adjusted individually during each clamping or disassembly, such as adjusting the position of the clamping plates one by one. This makes it impossible to achieve synchronous adjustment of the spacing of all clamping plates, resulting in many repetitive operations and long clamping time, which seriously affects the processing efficiency. Therefore, it is necessary to develop a wire cutting tooling for anti-deformation thin parts. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] A wire cutting fixture for preventing deformation of thin parts includes a base and a first support.

[0007] A tooling table is fixedly installed on the top of the base. Two transverse sliding openings are provided on the tooling table. A slider is slidably arranged in the groove of each sliding opening. A mounting plate is fixedly installed on the top of each slider. A clamping mechanism for clamping the side of the part is installed on the side wall of the mounting plate.

[0008] First brackets are fixedly installed on both sides of the top of the base. Two sliding rods are fixedly arranged between the two first brackets. The rods of the two sliding rods are slidably mounted with slide plates through linear bearings. The distance between the slide plates is located below the sliding opening and is perpendicular to it. A linkage rod is hinged to the lower end of each slide plate. The other ends of the four linkage rods are respectively hinged to the top of the slide plate. The base is provided with a drive locking mechanism for driving the slide plate to move and lock, so as to adjust the distance between the clamping mechanism and the parts.

[0009] As a preferred embodiment of the anti-deformation thin part wire cutting shape tooling described in this utility model, the clamping mechanism includes a threaded rod threaded through the side wall of the mounting plate, one end of the threaded rod is rotatably provided with a clamping plate for clamping the side of the part through a bearing, and the other end is fixedly provided with a first knob.

[0010] As a preferred embodiment of the anti-deformation thin part wire cutting shape tooling described in this utility model, each of the clamping plates is fixedly provided with a guide rod parallel to the threaded rod on its side wall, and the rod body of the guide rod slides through the side wall of the mounting plate through a linear bearing.

[0011] As a preferred embodiment of the anti-deformation thin part wire cutting shape tooling described in this utility model, the drive locking mechanism includes a rack fixed to the bottom of the slide plate. The overall length direction of the rack is consistent with the movement direction of the slide plate. Two second side plates are fixedly provided on the top of the base. A rotating rod is rotatably provided between the two second side plates through a bearing. A gear that meshes with the rack is fixedly provided on the rod body.

[0012] As a preferred embodiment of the anti-deformation thin part wire cutting shape tooling described in this utility model, the drive locking mechanism further includes a worm gear fixed to the rotating rod body, two third brackets are fixedly provided on the top of the base, and a worm gear meshing with the worm gear is rotatably provided between the two third brackets through a bearing, and a second knob is provided at one end of the third bracket.

[0013] The beneficial effects of this utility model are: for thin parts of the same batch with the same specifications, after the clamping plate is adjusted to the appropriate position for the first time by the threaded rod and the first knob in the clamping mechanism, there is no need to repeatedly adjust the individual clamping plates during subsequent clamping or disassembly. The sliding plate is driven to move by the driving locking mechanism, and all the sliders can be driven to slide synchronously in opposite directions in the sliding mouth through the linkage rod, so as to realize the synchronous adjustment of the spacing of all clamping plates, greatly reducing repetitive operations and quickly completing the clamping and disassembly of parts.

[0026] Example 1

[0027] This solution discloses a wire cutting fixture for anti-deformation thin parts, mainly including a base 100 and a first support 200. A fixture table 101 is fixedly installed on the top of the base 100. Two transverse sliding slots 102 are opened on the fixture table 101. Slider 103 is slidably arranged in the slots of each sliding slot 102. A mounting plate 104 is fixedly installed at the top of each slider 103. A clamping mechanism for clamping the side of the part is installed on the side wall of the mounting plate 104. The first support 200 is fixedly installed on both sides of the top of the base 100. Two sliding rods 201 are fixedly arranged between the two first supports 200. The rods of the two sliding rods 201 are slidably arranged with slide plates 202 through linear bearings. The distance between the slide plates 202 is below the sliding slots 102 and perpendicular to them. A linkage rod 203 is hinged to the lower end of each slider 103. The other ends of the four linkage rods 203 are respectively hinged to the top of the slide plates 202. A drive locking mechanism is provided on the base 100 for driving the slide plates 202 to move and lock, so as to adjust the distance between the clamping mechanism and the part.

[0028] Solution Analysis: This solution achieves synchronous clamping and adjustment of parts based on the parallelogram linkage principle and optimized sliding friction design. Two parallel transverse sliding openings 102 are provided on the tooling table 101, providing a guide trajectory for the sliders 103, ensuring that the sliders 103 can only slide in opposite directions laterally. The slide plate 202 cooperates with the slide rod 201 through a linear bearing, converting sliding friction into rolling friction, significantly reducing motion resistance, and allowing the slide plate 202 to move smoothly along the axis of the slide rod 201. Four linkage rods 203 are respectively hinged to the sliders 103 and the slide plate 202, forming a symmetrically distributed linkage structure. When the slide plate 202 moves along the slide rod 201, the linkage rods 203 transmit force through the hinge points, driving the four sliders 103 to move synchronously within the sliding openings 102—when the slide plate 202 moves in a certain direction, the linkage rods 203 push the sliders 103 closer together, and vice versa, pulling the sliders 103 away in the opposite direction, realizing synchronous spacing adjustment of all clamping mechanisms. The drive locking mechanism controls the displacement of the slide plate 202 and locks it through mechanical transmission, ensuring the stability of the adjusted clamping distance. This structural design avoids repetitive operation of individual adjustment clamping components and achieves batch synchronous adjustment through mechanical linkage, which conforms to the mechanical and kinematic principles of efficient processing.

[0029] Technical Effects: This solution achieves synchronous adjustment of the clamping mechanism through a linkage structure, effectively reducing repetitive operations when clamping or disassembling parts in the same batch, significantly shortening clamping time and improving processing efficiency. The cooperation between the transverse slide 102 and the slider 103, and the linear bearing connection between the slide plate 202 and the slide rod 201, ensure the smoothness and accuracy of the movement of each component, reducing clamping errors caused by movement offset. Simultaneously, the drive locking mechanism can stably lock the adjusted position, preventing changes in the clamping distance due to external forces during processing, thereby reducing the risk of deformation of thin parts due to unstable clamping and ensuring the dimensional accuracy of the machined parts.

[0030] Example 2

[0031] This solution discloses a wire cutting tooling for anti-deformation thin parts. Based on embodiment 1, the clamping mechanism includes a threaded rod 105 that is screwed through the side wall of the mounting plate 104. One end of the threaded rod 105 is rotatably mounted with a clamping plate 106 for clamping the side of the part via a bearing, and the other end is fixedly mounted with a first knob 107.

[0032] Solution Analysis: This solution achieves precise adjustment of clamping force based on the principle of screw drive. The threaded rod 105 is screwed to the side wall of the mounting plate 104, forming a helical pair structure. When the first knob 107 is rotated, the threaded rod 105 is displaced along its own axial direction—clockwise rotation of the first knob 107 pushes the clamping plate 106 closer to the part; counterclockwise rotation pulls the clamping plate 106 away from the part. The threaded rod 105 and the clamping plate 106 are connected by bearings, converting the rotational motion of the threaded rod 105 into the linear motion of the clamping plate 106, preventing the clamping plate 106 from twisting as the threaded rod 105 rotates, ensuring that the clamping plate 106 always contacts the side of the part with a flat surface. This structure utilizes the self-locking characteristic of screw drive (when the thread helix angle is less than the friction angle), allowing the clamping plate 106 to stably maintain its current position after the first knob 107 is stopped, preventing loosening due to force during clamping. Meanwhile, the first knob 107 increases the lever arm, making it easier for operators to manually apply a small force to adjust the displacement of the clamp 106, which is in line with ergonomic principles.

[0033] Technical Effects: This solution, through the cooperation of the threaded rod 105 and the first knob 107, achieves precise adjustment of the distance between the clamping plate 106 and the side of the workpiece. The clamping force can be flexibly adjusted according to the thickness of thin parts, improving adaptability to thin parts of varying thicknesses. The bearing connection ensures the linear movement of the clamping plate 106, avoiding uneven force on the side of the workpiece due to torsion and reducing the risk of localized deformation. The self-locking characteristic of the screw drive allows the clamping plate 106 to stably clamp the workpiece after adjustment, preventing displacement during processing and ensuring the accuracy of wire EDM. Furthermore, the first knob 107 simplifies the operation process and improves the convenience of clamping.

[0034] Example 3

[0035] This solution discloses a wire cutting tooling for anti-deformation thin parts. Based on embodiment 2, a guide rod 108 parallel to the threaded rod 105 is fixedly provided on the side wall of each clamping plate 106. The rod body of the guide rod 108 slides through the side wall of the mounting plate 104 through a linear bearing.

[0036] Solution Analysis: This solution improves the stability of the clamping plate 106's movement based on the principle of guiding constraints. The guide rod 108 is arranged parallel to the threaded rod 105 and slides with the mounting plate 104 via a linear bearing, forming a biaxial guiding structure for the clamping plate 106. When the threaded rod 105 moves the clamping plate 106, the guide rod 108 slides synchronously along the through hole of the mounting plate 104, limiting the displacement of the clamping plate 106 in the direction perpendicular to the axial direction of the threaded rod 105, thus preventing wobbling or offset of the clamping plate 106 due to uneven force or slight deflection of the threaded rod 105. The use of the linear bearing converts the sliding friction between the guide rod 108 and the mounting plate 104 into rolling friction, reducing motion resistance and ensuring a smooth, uninterrupted guiding process. This structure ensures that the movement trajectory of the clamping plate 106 strictly follows the axial direction of the threaded rod 105, guaranteeing parallel contact between the clamping plate 106 and the side of the part, and avoiding localized stress concentration. Meanwhile, the guide rod 108 provides support for the clamping plate 106, enhancing its resistance to deformation and preventing it from bending under clamping force.

[0037] Technical Effects: This solution, through the sliding engagement of the guide rod 108 and the mounting plate 104, significantly improves the stability and accuracy of the movement of the clamping plate 106, reducing part clamping errors caused by misalignment. The dual-axis guiding structure ensures uniform contact between the clamping plate 106 and the side of the part, resulting in more balanced force on the part and reducing the risk of deformation of thin parts due to excessive localized force. The use of linear bearings makes the guiding process smoother, reduces operating resistance, and improves adjustment efficiency. Furthermore, the supporting effect of the guide rod 108 on the clamping plate 106 enhances the overall rigidity of the clamping mechanism and extends the service life of the tooling.

[0038] Example 4

[0039] This solution discloses a wire cutting tooling for anti-deformation thin parts. Based on embodiment 1, the drive locking mechanism includes a rack 204 fixed to the bottom of the slide plate 202. The overall length direction of the rack 204 is consistent with the movement direction of the slide plate 202. Two second side plates 205 are fixedly installed on the top of the base 100. A rotating rod 206 is rotatably installed between the two second side plates 205 through a bearing. A gear 207 that meshes with the rack 204 is fixedly installed on the rod of the rotating rod 206.

[0040] Solution Analysis: This solution achieves precise displacement control of the slide plate 202 based on the gear and rack transmission principle. The rack 204 is fixed to the bottom of the slide plate 202, with its teeth aligned with the direction of movement of the slide plate 202. The gear 207 is fixed to the rotating rod 206 and meshes with the rack 204, forming a gear and rack transmission pair. When the rotating rod 206 rotates under the bearing support of the second side plate 205, the gear 207 rotates synchronously with the rotating rod 206, driving the rack 204 to move axially through tooth surface meshing, thereby driving the slide plate 202 to slide along the slide rod 201. The gear and rack transmission has the characteristic of a constant transmission ratio, which can accurately convert the rotation angle of the rotating rod 206 into the linear displacement of the slide plate 202, achieving precise adjustment of the clamping mechanism spacing. The second side plate 205 provides stable support to both ends of the rotating rod 206, ensuring the correct meshing clearance between the gear 207 and the rack 204, and avoiding jamming or tooth skipping during transmission. The use of bearings reduces the rotational resistance of the rotating rod 206, making the transmission process smoother and reducing the force required for manual operation.

[0041] Technical Effects: This solution achieves precise displacement control of the slide plate 202 through rack and pinion transmission, making the adjustment of the clamping mechanism spacing more accurate and improving the adaptability to parts of different specifications. The constant transmission ratio ensures the stability of the adjustment process and reduces part clamping deviations caused by transmission errors. The supporting role of the second side plate 205 and the low resistance characteristics of the bearings make the driving process smoother, reduce the difficulty of operation, and improve clamping efficiency. At the same time, the rigid meshing structure of the rack and pinion enhances the load-bearing capacity of the drive locking mechanism, enabling it to stably withstand the gravity and motion reaction force of the slide plate 202 and the linkage components, ensuring the long-term reliable operation of the tooling.

[0042] Example 5

[0043] This solution discloses a wire cutting tooling for anti-deformation thin parts. Based on embodiment 4, the drive locking mechanism further includes a worm gear 208 fixed on the rod body of the rotating rod 206. Two third brackets 209 are fixedly installed on the top of the base 100. A worm 210 meshing with the worm gear 208 is rotatably installed between the two third brackets 209 through a bearing. A second knob 211 is installed at one end of the third bracket 209.

[0044] Solution Analysis: This solution utilizes the worm gear transmission principle to achieve self-locking and efficient driving of the locking mechanism. The worm gear 208 is fixed to the rotating rod 206, and the worm 210 is supported by a bearing on the third bracket 209 and meshes with the worm gear 208, forming a worm gear transmission pair. When the second knob 211 is rotated, the worm 210 rotates, driving the worm gear 208 to rotate, which in turn drives the rotating rod 206 and gear 207 to rotate, thus adjusting the displacement of the slide plate 202. The worm gear transmission has a reverse self-locking characteristic (the worm can drive the worm gear, but the worm gear cannot drive the worm). When the second knob 211 is stopped, the meshing relationship between the worm 210 and the worm gear 208 prevents the rotating rod 206 from rotating in the opposite direction, thereby locking the position of the slide plate 202 and preventing changes in the clamping distance due to external forces. Meanwhile, the worm gear drive has a large transmission ratio, which can convert the small-angle rotation of the second knob 211 into a large-angle rotation of the rotating rod 206, enabling rapid adjustment of the slide plate 202. Moreover, the operator only needs to apply a small force to drive it, which conforms to the principle of labor-saving design. The stable support of the third bracket 209 for the worm 210 ensures meshing accuracy, while the bearing reduces rotational resistance and ensures smooth transmission.

[0045] Technical Benefits: This solution utilizes the self-locking characteristics of the worm gear to ensure the drive locking mechanism stably locks the position of the slide plate 202 after adjustment. This completely avoids changes in the clamping distance caused by vibration or external forces during processing, significantly improving the stability of part clamping and reducing the risk of deformation of thin parts. The larger transmission ratio design makes the adjustment process more effortless and efficient, and the second knob 211 further simplifies operation and enhances the human-machine interface. The support of the third bracket 209 and the low-resistance characteristics of the bearings ensure the stability and durability of the transmission, extending the service life of the tooling. The overall structure integrates the drive and locking functions, reducing the use of additional locking components, simplifying the tooling structure, and lowering manufacturing costs.

[0046] Working Principle: This solution mainly achieves efficient and stable clamping of thin parts through mechanical linkage and compound transmission principles. First, the second knob 211 in the drive locking mechanism drives the worm gear 210 to rotate. The worm gear 210 meshes with the worm wheel 208, transmitting the rotational motion to the rotating rod 206. The gear 207 on the rotating rod 206 meshes with the rack 204 at the bottom of the slide plate 202, converting the rotational motion into linear motion of the slide plate 202 along the slide rod 201. The slide plate 202 is hinged to four sliders 103 through four linkage rods 203. When the slide plate 202 moves, the linkage rods 203 push or pull the sliders 103 to slide synchronously in opposite directions within the sliding opening 102 of the tooling table 101, realizing the adjustment of the spacing of the clamping mechanism on the mounting plate 104. In the clamping mechanism, rotating the first knob 107 drives the threaded rod 105 to rotate. The threaded rod 105 is screwed into the mounting plate 104, pushing the clamping plate 106 to move linearly. The guide rod 108 ensures that the clamping plate 106 moves smoothly along the axial direction of the threaded rod 105, ultimately achieving precise clamping of the part. The entire process ensures motion accuracy through a combination of gear and rack and worm gear transmission, achieves synchronous adjustment through the cooperation of the linkage rod and the slider, and achieves fine clamping through helical transmission and guide structure. All components work together to complete the clamping and locking of the part.

[0047] Technical benefits of implementing this solution: This solution significantly reduces repetitive clamping operations for the same batch of parts through a synchronous adjustment structure, thereby significantly improving processing efficiency. The combined transmission of gear rack and worm gear ensures the accuracy and stability of the clamping mechanism spacing adjustment, avoiding part clamping deviations caused by adjustment errors. The cooperation between the linkage rod and the slider ensures synchronous movement of all clamping mechanisms, guaranteeing uniform force on the parts and reducing the risk of deformation of thin parts due to excessive local force. The fine adjustment function and guiding structure of the clamping plate 106 improves the adaptability to parts of different specifications, and the clamping process is stable and reliable, avoiding part displacement during processing. In addition, the self-locking characteristics of the worm gear and the low-resistance design of each component make tooling operation convenient and labor-saving, while enhancing long-term durability, thus improving the overall quality and efficiency of wire EDM processing of thin parts.
