Abstract
Description
Technical Field
[0001] This application relates to the field of cutting device technology, and more specifically, to a positioning mold and a cutting device. Background Technology
[0002] In the production process of automotive parts, rough workpieces often have burrs, which need to be removed using a cutting device. Typically, when cutting burrs, the workpiece is placed on the die of the cutting device, and the process hole for the burr is fitted onto the locating pin of the die. Then, the cutting machine cuts the burrs. Therefore, the locating pin at the die inevitably wears down, becoming a consumable part that needs to be replaced after a period of use.
[0003] Currently, the locating pin is installed by applying glue to its outer wall, inserting it into the locating hole of the mold, and then bonding it in place. Replacing the locating pin requires forceful disassembly, which is inconvenient, inefficient, and can damage the mold, affecting its lifespan. Utility Model Content
[0004] In view of the above-mentioned shortcomings, this application provides a positioning mold and a cutting device to improve the problems of low disassembly and assembly efficiency of positioning pins and easy damage to the mold in related technologies.
[0005] This application is implemented as follows:
[0006] In a first aspect, an example of this application provides a positioning mold, including a mold frame, a placement platform for placing a workpiece on one side of the mold frame, and the placement platform having at least one positioning hole. The positioning mold also includes positioning pins corresponding to the positioning holes and pressure blocks corresponding to the positioning pins. Each positioning pin has a first segment with a larger cross-section and a second segment with a smaller cross-section connected to each other. The first segment is inserted into and fits into the positioning hole. The pressure block has a limiting hole, the second segment extends out of the limiting hole, and the end face of the first segment facing the second segment abuts against the surface of the pressure block facing the first segment. The pressure block is detachably connected to the placement platform to selectively press the first segment into the positioning hole. One end of the second segment extending out of the limiting hole is used for inserting a process hole of the workpiece to position the workpiece.
[0007] In the above implementation process, when using the positioning mold, the workpiece is placed on the placement table of the mold frame, and the process hole of the workpiece is fitted onto the end of the second section of the positioning pin that protrudes from the limiting hole to position the workpiece. The first section of the positioning pin is inserted into the positioning hole and fits with it, allowing the positioning hole to position the positioning pin. A pressure block is fitted onto the second section of the positioning pin. Because the cross-section of the first section of the positioning pin is too large to pass through the limiting hole of the pressure block, it will abut against the surface of the pressure block facing the first section. Therefore, when it is necessary to fix the positioning pin to the positioning hole, it is not necessary to apply glue to the positioning pin; the pressure block can be detachably connected to the placement table of the mold frame. When the positioning pin is worn and needs to be replaced, the pressure block is removed from the placement table of the mold frame, and the positioning pin can be removed from the positioning hole without forceful disassembly. The positioning hole will not be damaged during disassembly and assembly, thus ensuring the positioning accuracy of the positioning mold and improving its service life. Using the pressure block to tighten or loosen the positioning pin can improve the efficiency of the positioning pin's disassembly and assembly.
[0008] In conjunction with the first aspect, in one optional embodiment, the positioning pin is a circular cylindrical structure, the outer diameter of the first segment is larger than the outer diameter of the second segment, the diameter of the limiting hole is smaller than the outer diameter of the first segment, and the end of the second segment away from the first segment is frustoconical.
[0009] In the above implementation process, the locating pin is set as a cylindrical structure with different outer diameters, such that the outer diameter of the first segment is larger than that of the second segment, and the limiting hole can fit over the second segment with a smaller diameter than that of the first segment. Therefore, when the pressure block is connected to the mold base's placement table, the first segment cannot pass through the limiting hole and will abut against the surface of the pressure block facing the first segment. This allows the pressure block to press the locating pin firmly against the positioning hole of the placement table, eliminating the need to apply glue to the locating pin. When removing the locating pin, simply remove the pressure block from the mold base's placement table and withdraw the second segment of the locating pin to pull the locating pin out of the positioning hole. No forceful disassembly is required, reducing wear on the positioning hole during the installation and removal process and thus extending the service life of the positioning mold. Furthermore, setting the end of the second segment of the locating pin furthest from the first segment to a frustum shape facilitates fitting the workpiece onto the locating pin.
[0010] In conjunction with the first aspect, in one alternative embodiment, the pressure block and the placement table are detachably connected by threaded fasteners.
[0011] In the above implementation process, the pressure block and the placement platform are connected by a threaded fastener. When disassembling or assembling the pressure block, the threaded fastener can be turned, which can improve the disassembly and assembly efficiency of the pressure block, and thus improve the disassembly and assembly efficiency of the positioning pin.
[0012] In conjunction with the first aspect, in one optional embodiment, a receiving cavity is provided in the middle of the placement stage, and a positioning hole is provided on the circumferential outer wall of the placement stage corresponding to the opening of the receiving cavity.
[0013] In the production of automotive parts, it is often necessary to cut the burrs on certain grooved products with flanges. In this process, a receiving cavity is set in the middle of the placement table. The non-cutting parts of the workpiece are placed inside the cavity, and the process holes of the part to be cut are fitted onto the locating pins at the locating holes outside the cavity. This allows the cutting machine to cut the burrs outside the cavity, reducing the likelihood of deformation of the workpiece portion inside the cavity during cutting and improving the quality of the cut workpiece.
[0014] In conjunction with the first aspect, in an alternative embodiment, the placement stage has a slit on its circumferential outer wall corresponding to the opening of the receiving cavity, and a positioning hole is located on the side of the slit away from the receiving cavity. The slit allows the cutting blade to pass through.
[0015] In the above implementation process, a gap is set between the positioning hole and the receiving cavity. When the workpiece part extending out of the receiving cavity is cut by the cutting machine, the cutting blade can extend into the gap, avoiding contact between the cutting blade and the placement table, thus preventing wear on the placement table and the cutting blade and improving the service life of the positioning mold.
[0016] In conjunction with the first aspect, in an optional embodiment, the receiving cavity is rectangular, and the placement platform is provided with two positioning holes on the circumferential outer wall corresponding to the opening of the receiving cavity. The two positioning holes are located on two opposite sides of the rectangle, and the two positioning holes are located near the diagonal of the sides.
[0017] In the production of automotive parts, it is often necessary to cut the burrs on certain rectangular grooved products with flanges. In this process, a positioning hole is provided on each side of the receiving cavity, roughly diagonally distributed. Each positioning hole is fitted with a positioning pin via a pressure block. When fixing the workpiece, the two positioning pins can position the workpiece at roughly diagonal positions on both sides, improving the positioning accuracy.
[0018] In conjunction with the first aspect, in one optional embodiment, a notch is provided on the circumferential outer wall of the placement platform, and a positioning hole is provided within the notch. A pressure block is detachably connected to the notch, and the side of the pressure block facing away from the positioning hole is flush with the circumferential outer wall.
[0019] In the above implementation process, a notch is set on the circumferential outer wall of the placement platform, and the positioning hole is set in the notch. When the positioning pin in the positioning hole is fixed by the pressure block, the pressure block can be embedded in the notch to improve the flatness of the placement platform, improve the stability of the workpiece placement and the cutting quality.
[0020] In conjunction with the first aspect, in an optional embodiment, a plurality of pressure plates are spaced apart along the circumferential outer wall of the cavity opening, each pressure plate being mounted on the mold frame by a drive member, the drive member selectively driving the pressure plate to rotate to press against the edge of the workpiece.
[0021] In the above implementation process, after the workpiece is placed on the placement table, the driving component can drive the pressure plate to rotate, pressing the pressure plate against the edge of the workpiece so that the workpiece can be cut by the cutting machine.
[0022] In conjunction with the first aspect, in one alternative embodiment, the mold frame is provided with a mounting hole on the side facing away from the placement table for mounting the positioning mold onto the worktable of the cutting device.
[0023] In the above implementation process, a mounting hole is provided on the side of the mold frame away from the placement table. The positioning mold can be installed on the worktable of the cutting device through the mounting hole so that the workpiece at the mold can be cut by the cutting machine in the cutting device.
[0024] In a second aspect, an example of this application provides a cutting apparatus including the positioning mold provided in the first aspect.
[0025] In the above implementation process, the positioning mold provided in this application embodiment is installed in the cutting device. The mold's placement platform is equipped with positioning pins, which allow the process holes of the workpiece to be cut to be fitted onto the positioning pins for positioning. The workpiece is then cut using the cutting machine in the cutting device. Since the positioning pins need to frequently contact the workpiece, unavoidable wear will occur. The positioning pins are consumable parts and need to be replaced periodically. Because the positioning pins in the positioning mold provided in this application embodiment are fixed to the positioning holes of the placement platform by pressure blocks, it is not necessary to apply glue when fixing the positioning pins, and it is not necessary to forcefully disassemble them. The positioning pins can be quickly disassembled by removing and installing the pressure blocks, which reduces wear on the positioning holes during disassembly and assembly, increases the service life of the positioning mold, and improves the cutting quality of the cutting device.

[0035] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

Therefore, they should not be construed as limitations on the embodiments of this application.
[0040] In the production of automotive parts, rough workpieces often have burrs, which need to be removed using a cutting device in subsequent processes. Typically, when cutting burrs, the workpiece is placed on the die of the cutting device, and the process holes for the burrs are fitted onto the locating pins of the die to position the workpiece. Then, the cutting machine in the cutting device cuts off the burrs.
[0041] During the use of the cutting device, the locating pins need to be frequently inserted and withdrawn from the process holes of the workpiece, resulting in frequent friction with the workpiece. This inevitably causes wear on the locating pins, making them vulnerable parts. Once worn, the locating pins cannot effectively position the workpiece, leading to misalignment during cutting and affecting workpiece quality. Therefore, it is necessary to replace the locating pins in the positioning mold in a timely manner.
[0042] Currently, to improve the positional accuracy of the locating pin within the positioning mold, the locating pin is installed by applying adhesive to its outer wall, inserting it into the positioning hole of the mold, and bonding it to the positioning hole 12. However, if the locating pin is fixed by screwing it into the threaded positioning hole, the thread clearance will affect its positional accuracy. Therefore, fixing the locating pin to the positioning hole by applying adhesive to its outer wall ensures that the radial dimension of the locating pin matches the diameter of the positioning hole, thus improving the installation accuracy of the locating pin 20.
[0043] However, fixing the locating pin by applying glue to the outer wall of the locating pin requires strong disassembly when replacing the locating pin, which is inconvenient and inefficient. It can also damage the locating hole in the mold, affecting the positioning accuracy and reducing the life cycle of the mold.
[0044] Therefore, this application further improves the positioning mold in the cutting device, thereby improving the replacement efficiency of the positioning pins and extending the service life of the positioning mold to a certain extent. To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0045] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 4 The positioning mold 1 provided in this embodiment includes a mold frame 10. A placement platform 11 for placing workpieces is provided on one side of the mold frame 10, and the placement platform 11 has at least one positioning hole 12. The positioning mold 1 also includes positioning pins 20 corresponding to each positioning hole 12 and pressure blocks 30 corresponding to each positioning pin 20. Please refer to... Figure 5 The locating pin 20 has a first segment 21 with a larger cross-section and a second segment 22 with a smaller cross-section that are connected to each other. The first segment 21 is inserted into and fits into the locating hole 12. Please refer to... Figure 6 and Figure 7 The pressure block 30 is provided with a limiting hole 31. The second segment 22 extends through the limiting hole 31, and the end face of the first segment 21 facing the second segment 22 abuts against the surface of the pressure block 30 facing the first segment 21. The pressure block 30 is detachably connected to the placement table 11 so that the first segment 21 can be selectively pressed into the positioning hole 12. One end of the second segment 22 extending through the limiting hole 31 is used for the process hole of the workpiece to be fitted into for positioning the workpiece.
[0046] When positioning a workpiece using the positioning mold 1 provided in this application embodiment, the workpiece is placed on the placement platform 11 of the mold frame 10, and the process hole of the workpiece is fitted onto the end of the second section 22 of the positioning pin 20 that protrudes from the limiting hole 31 to position the workpiece. Since the first section 21 of the positioning pin 20 is directly inserted into the positioning hole 12 and engages with it, the gap between the positioning pin 20 and the positioning hole 12 is smaller than that of the positioning pin 20 being screwed into the positioning threaded hole, resulting in higher installation accuracy of the positioning pin 20 on the placement platform 11.
[0047] When the positioning pin 20 needs to be replaced due to wear, the pressure block 30 is removed from the placement table 11, and the second section 22 of the positioning pin 20 is pulled out. Then, the first section 21 of the positioning pin 20 is pulled out of the positioning hole 12 at the placement table 11. Since the positioning pin 20 and the positioning hole 12 are not fixed with glue, no strong disassembly is required when removing the positioning pin 20, and there is basically no wear on the positioning hole 12. This not only improves the positioning accuracy of the positioning mold 1, but also extends the service life of the positioning mold 1.
[0048] After removing the worn locating pin 20 from the locating hole 12, the first segment 21 of the new locating pin 20 can be inserted into the locating hole 12 without applying glue to the outer wall of the locating pin 20. Then, the limiting hole 31 of the pressure block 30 is fitted onto the second segment 22 of the new locating pin 20. Since the first segment 21 of the locating pin 20 will abut against the surface of the pressure block 30 facing the first segment 21, after the pressure block 30 is detachably connected to the placement platform 11, the pressure block 30 can be used to press the locating pin 20 into the locating hole 12, thereby fixing the locating pin 20 in the locating hole 12.
[0049] The following describes in further detail the mold frame 10, positioning pin 20 and pressure block 30 in the positioning mold provided in the embodiments of this application, with reference to the accompanying drawings.
[0050] To facilitate the placement of the workpiece to be cut, a placement platform 11 is provided on one side of the mold frame 10, and a positioning hole 12 for installing the positioning pin 20 is provided at the placement platform 11. The position of the positioning pin 20 is positioned by the positioning hole 12.
[0051] This application does not limit the specific structure of the placement stage 11, and it can be adjusted accordingly based on the shape of the workpiece to be cut. In some embodiments, when the workpiece to be cut has a shell-like groove structure with flanges, please refer to [reference needed]. Figure 1 and Figure 2 A receiving cavity 13 can be provided at the placement table 11 to accommodate the workpiece, and the flange of the workpiece can overlap the circumferential outer wall of the placement table 11 corresponding to the opening of the receiving cavity 13. Typically, burrs form at the edge of the flange of the workpiece to be cut, which need to be removed. To facilitate the removal of burrs, a process hole can be provided at the burrs, and a positioning hole 12 can be provided at the circumferential outer wall of the placement table 11 corresponding to the opening of the receiving cavity 13. A positioning pin 20 is provided in the positioning hole 12, and the process hole at the burrs is fitted onto the positioning pin 20 to position the burrs of the workpiece. Then, the cutting machine in the cutting device removes the burrs.
[0052] As an example, the workpiece to be cut is a quadrilateral groove structure with flanges around its perimeter, and the edges of the flanges form burrs. The receiving cavity 13 at the placement table 11 is a quadrilateral structure, and the positioning hole 12 is located on the circumferential outer wall of the placement table 11 corresponding to the opening of the receiving cavity 13. The distance between the positioning hole 12 and the opening of the receiving cavity 13 is not less than the width of the flange, so that the cutting machine can cut the burrs along the edge of the flange.
[0053] Furthermore, in order to reduce the impact of the placement stage 11 on the cutting blade and avoid friction between the placement stage 11 and the cutting blade, in some embodiments, please continue to refer to... Figure 3 A slit 14 can be provided on the placement platform 11 at a position corresponding to the opening between the positioning hole 12 and the receiving cavity 13. When the cutting blade cuts the burr located between the positioning hole 12 and the receiving cavity 13, the end of the cutting blade can extend into the slit 14 and cut along the slit 14. It can be understood that the slit 14 is located at the edge of the workpiece flange, and the cutting blade can cut the edge of the flange along the slit 14.
[0054] Furthermore, in order to reduce the weight of the mold frame 10, the bottom wall of the mold frame 10 corresponding to the receiving cavity 13 can be set as a hollow structure.
[0055] Alternatively, in some embodiments, when the workpiece to be cut is a flat structure, the placement platform 11 can be configured as a flat plate. Accordingly, in order to reduce the weight of the mold frame 10, the flat placement platform 11 can be configured as a hollow structure.
[0056] Furthermore, in order to facilitate the installation of the mold frame 10 on the worktable of the cutting device, in some embodiments, a mounting hole (not shown in the figure) can be provided on the side of the mold frame 10 away from the placement table 11, and the positioning mold 1 can be installed on the worktable using the mounting hole.
[0057] Furthermore, when a gap 14 is provided at the position of the placement platform 11 corresponding to the position between the positioning hole 12 and the opening of the receiving cavity 13, in order to improve the stability of the mold frame 10, a reinforcing rib can be provided on the outer edge of the placement platform 11 corresponding to the gap 14.
[0058] This application does not limit the specific shape of the positioning hole 12. In some embodiments, the positioning hole 12 may be a circular hole. Alternatively, in other embodiments, the positioning hole 12 may be prismatic.
[0059] The positioning pin 20 has a first segment 21 and a second segment 22 connected to each other. The first segment 21 is inserted into the positioning hole 12, and the part of the first segment 21 inserted into the positioning hole 12 matches the shape and size of the positioning hole 12. The second segment 22 of the positioning pin 20 is used for the process hole of the workpiece to be fitted into, thereby positioning the workpiece. Furthermore, the second segment 22 of the positioning pin 20 can extend into the limiting hole 31 of the pressure block 30, and the first segment 21 of the positioning pin 20 cannot pass through the limiting hole 31, but will abut against the surface of the pressure block 30 facing the first segment 21.
[0060] This application does not limit the specific structure of the locating pin 20; please refer to other embodiments for further details. Figure 5 The positioning pin 20 has a circular cylindrical structure. The outer diameter of the first segment 21 is larger than the outer diameter of the second segment 22. The outer diameter of the second segment 22 is smaller than the inner diameter of the limiting hole 31. The outer diameter of the first segment 21 is larger than the inner diameter of the limiting hole 31, so that the second segment 22 can pass through the limiting hole 31 and the first segment 21 can abut against the hole wall of the limiting hole 31.
[0061] Furthermore, in order to facilitate the fitting of the workpiece onto the second segment 22, the end of the second segment 22 away from the first segment 21 can be configured as a frustum-shaped structure or a conical structure.
[0062] Alternatively, in some other embodiments, the positioning pin 20 is in the shape of a circular column, and an outward protrusion is provided at the end of the second segment 22 near the first segment 21. When the first segment 21 is passed through the limiting hole 31, the protrusion can abut against the outer wall of the limiting hole 31.
[0063] It is understood that in the positioning mold 1 provided in this application embodiment, the number of positioning pins 20 is the same as the number of positioning holes 12, and a positioning pin 20 is provided at each positioning hole 12.
[0064] As an example, when the receiving cavity 13 has a quadrilateral structure, two positioning holes 12 can be provided on the circumferential outer wall of the receiving cavity 13. The two positioning holes 12 are located on opposite sides of the circumferential outer wall of the quadrilateral to facilitate positioning of opposite sides of the workpiece. Furthermore, the two positioning holes 12 are located near the diagonal of the edge. That is, the two positioning holes 12 are roughly distributed diagonally. A positioning pin 20 is inserted into each positioning hole 12.
[0065] The pressure block 30 is provided with a limiting hole 31, through which the second section 22 of the positioning pin 20 passes and abuts against the first section 21. The pressure block 30 can be detachably connected to the placement table 11 so as to press the positioning pin 20 into the positioning hole 12 or loosen the positioning pin 20.
[0066] This application does not limit how the pressure block 30 is detachably connected to the placement platform 11. In some embodiments, the pressure block 30 is connected to the placement platform 11 by a threaded fastener 32.
[0067] As an example, a first threaded hole is provided on the placement platform 11 near the positioning hole 12, and a second threaded hole is provided on the pressure block 30 near the limiting hole 31. When installing the positioning pin 20, the first segment 21 of the positioning pin 20 is inserted into the positioning hole 12 to position the positioning pin 20. Then, the limiting hole 31 of the pressure block 30 is fitted onto the second segment 22, so that the second segment 22 protrudes from the limiting hole 31. Then, a screw or other threaded fastener 32 is used to pass through the second threaded hole and the first threaded hole to fix the pressure block 30 to the placement platform 11. When it is necessary to remove the positioning pin 20, the threaded fastener 32 is unscrewed to remove the pressure block 30 and the positioning pin 20.
[0068] Furthermore, in order to improve the tightness of the pressure block 30, in some embodiments, a second threaded hole can be provided on each side of the pressure block 30 corresponding to the radial side of the limiting hole 31, and a first threaded hole can be provided on each side of the placement platform 11 corresponding to the radial side of the positioning hole 12. When the positioning pin 20 is tightened, two threaded fasteners 32 pass through the first threaded hole and the second threaded hole in a one-to-one correspondence.
[0069] Furthermore, in some embodiments, to illustrate the effect of the pressure block 30 on the surface flatness of the placement platform 11, please refer to [the relevant documentation / reference needed]. Figure 3A notch 15 can be provided at the placement platform 11, and a positioning hole 12 can be placed inside the notch 15. When fixing the positioning pin 20, the first section 21 of the positioning pin 20 is inserted into the positioning hole 12 inside the notch 15, and then the pressure block 30 is passed through the second section 22 of the positioning pin 20 to fix the pressure block 30 inside the notch 15. After the pressure block 30 is fixed in the notch 15, the surface of the pressure block 30 facing away from the positioning hole 12 is flush with the placement platform 11.
[0070] It is understood that in the positioning mold 1 provided in this application embodiment, the number of pressure blocks 30 is the same as the number of positioning pins 20, and a pressure block 30 is provided at each positioning pin 20.
[0071] Furthermore, to further improve the cutting quality, in some embodiments, a plurality of pressure plates 41 are spaced apart along the circumferential outer wall of the opening of the receiving cavity 13, and each pressure plate 41 is disposed on the mold frame 10 by a drive member 42. The drive member 42 can drive the pressure plate 41 to rotate so as to press the pressure plate 41 against the edge of the workpiece.
[0072] As an example, the pressure plate 41 is T-shaped, having a connecting section for connecting the drive member 42 and a pressing section for pressing the edge of the workpiece. The drive member 42 can be a rotary cylinder, with its fixed end mounted on the mold frame 10 and its movable end connected to the connecting section of the pressure plate 41. When it is necessary to press the pressure plate 41 against the edge of the workpiece, the cylinder rotates the connecting section, thereby causing the pressure plate 41 to rotate and press against the edge of the workpiece. When it is necessary to remove or place the workpiece, the cylinder can rotate the connecting section, thereby causing the pressing section to rotate beyond the edge of the placement table 11.
[0073] This application also provides a cutting device (not shown in the figure), which includes a cutting machine and a positioning mold 1 provided in this application embodiment. The positioning mold 1 is disposed at the worktable of the cutting device.
[0074] This application does not limit the specific type of cutting machine; appropriate selections can be made based on conventional cutting machines in the art. As an example, the cutting machine includes a robotic arm and a cutting blade. The robotic arm can drive the cutting blade to move along the cutting position to cut the workpiece at that position.
[0075] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
