Description

Technical Field

[0001] The present invention relates to the technical field of gear shapers, and more specifically, to a gear shaper. Background Art

[0002] A gear shaper is a metal cutting machine tool that uses a gear shaper cutter to machine internal and external straight and helical cylindrical gears and other tooth-shaped parts by the generation method.

[0003] Traditional gear shapers usually rely on manual or simple mechanical systems for operation, with limited machining accuracy and low production efficiency. With the progress of technology and the increasing demand for higher precision and greater productivity in the industry, the research and development and application of modern gear shapers have become more focused on efficiency and accuracy. However, when the gear shaper cutter moves downward to perform gear shaping operations on the blank, a large amount of debris adheres to the gear shaper cutter and the blank. When the gear shaper cutter moves upward, the debris above the gear shaper cutter contacts the surface of the machined blank and the surface of the tool, causing wear on the surface of the blank and the tool surface, which not only affects the machining quality of the blank but also shortens the service life of the tool.

[0004] In response to the above problems, some solutions have also been given in the prior art. For example, the Chinese invention patent with the publication number CN118404379B discloses an automatic gear shaping for gear processing. This device drives the cleaning roller to move synchronously in the horizontal direction through a control box and a support box to adjust the initial cleaning position of the cleaning roller. When the cleaning roller moves to a preset position, it is driven by a horizontal driving structure to move towards one of the cleaning holes, and a mobile self-rotating structure drives the rotating shaft to rotate. The rotating shaft drives the cleaning roller to rotate through a transmission unit, and the cleaning roller cleans the top of the machine tool body. Finally, the cleaning roller pushes the scrap cleaned out through the cleaning hole into the collection box. Although the prior art can clean the scrap during the gear shaping process, during the gear shaping process, the gear shaper cutter and the blank will rub against each other, and then the temperature of the gear shaper cutter and the blank will increase during the rubbing process. Then, under the action of thermal expansion and contraction, the gear shaper cutter and the blank will deform, shortening the service life of the tool and at the same time affecting the machining quality of the blank. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a gear shaper that can achieve the purpose of improving the machining quality of the blank.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A gear shaper includes a workbench, a mounting frame is fixedly installed on the top wall of the workbench, a hydraulic rod is installed on the mounting frame, a gear shaper cutter is provided on the hydraulic rod, a fixing component for fixing the blank is provided on the top wall of the workbench, and a temperature reduction component is provided on the workbench; The cooling component includes a water cylinder fixedly installed on the bottom wall of the workbench. A waste opening communicating with the water cylinder is provided on the top wall of the workbench. A piston plate is vertically slidably installed in the water cylinder. A vertical rod fixedly connected to the insertion knife is fixedly installed on the piston plate. A liquid inlet valve with its output end facing downward is fixedly installed on the piston plate. A liquid discharge valve is installed on the water cylinder. A water pipe is fixedly installed on the output end of the liquid discharge valve. A collection component for collecting waste is provided on the workbench.

[0008] Further, the collection component includes a collection box detachably installed on the bottom wall of the workbench. A collection opening communicating with the collection box is provided on the side wall of the waste opening. A filter screen for filtering waste is fixedly installed in the waste opening.

[0009] Further, an annular plate is rotatably installed on the filter screen. A scraping plate fitting with the filter screen is fixedly installed on the annular plate. A spiral groove is provided on the annular plate, and a vertical groove communicating with the spiral groove is provided on the annular plate. A convex block slidably matched with the spiral groove is fixedly installed on the vertical rod.

[0010] Further, a hollow rod is rotatably installed on the workbench. A grinding disc is fixedly installed on the top wall of the hollow rod. A linkage groove is provided on the grinding disc. A belt is jointly installed between the hollow rod and the annular plate.

[0011] Further, the fixing component includes a rotating rod rotatably installed on the workbench. The rotating rod is rotatably matched with the hollow rod. A three-jaw chuck for fixing the gear blank is fixedly installed at the top end of the rotating rod. A stepping motor with its output end fixedly connected to the rotating rod is fixedly installed on the bottom wall of the workbench.

[0012] Further, steel balls matched with the three-jaw chuck are fixedly installed on the top wall of the hollow rod.

[0013] Further, a sliding groove is provided on the insertion knife. A disc is slidably installed in the sliding groove. The disc is fixedly connected to the output end of the hydraulic rod. A rotating groove is provided on the side wall of the sliding groove. A slider slidably matched with the rotating groove is fixedly installed on the disc.

[0014] Further, the surfaces of the convex block and the slider are both smooth mirror surfaces.

[0015] Further, support rods are symmetrically installed between the top wall of the workbench and the mounting frame.

[0016] Further, limiting rods slidably matched with the piston plate are symmetrically and fixedly installed on the inner bottom wall of the water cylinder.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this solution, by setting up a water cylinder, during the downward movement of the inserting tool, the piston plate is driven downward by the vertical rod. During the downward movement of the piston plate, the water flow below the piston plate in the water cylinder is squeezed and flows through the drain valve into the water pipe, and then the water flow flows through the water pipe to the gear blank cutting area. When the water flow passes through the gear blank cutting area, it can drive the debris at the cutting area downward, thus avoiding the influence of debris on the cutting effect. At the same time, when the water flow passes through the cutting area, it can also cool down the gear blank and the inserting tool, thus avoiding the deformation of the gear blank and the inserting tool due to excessive temperature, which affects the quality of the finished product, and plays a role in improving the quality of the finished product; (2) In this solution, by means of a grinding disc, while the vertical rod drives the scraping plate to clean the debris on the top wall of the filter screen through the convex block, spiral groove and annular plate, the annular plate drives the hollow rod to rotate through the belt during the rotation process, and the grinding disc rotates during the rotation process of the hollow rod. Then, during the rotation process of the grinding disc, the burrs on the bottom wall of the gear blank can be processed, further improving the quality of the finished gear blank; (3) In this solution, through the cooperation of the rotating groove and the slider, when the output end of the hydraulic rod contracts and drives the disc to move upward along the sliding groove, the disc drives the slider to slide along the rotating groove again, and the inserting tool is reversed and reset. When the inserting tool drives the cutting teeth to move away from the gear blank, the top wall of the disc contacts the top wall of the sliding groove, and then the disc drives the inserting tool to move upward through the sliding groove, thus avoiding scratching the surface of the processed gear blank during the reset process of the inserting tool, reducing the wear of the gear shaper cutter, being beneficial to improving the quality of gear processing, and at the same time improving the service life of the gear shaper cutter, further improving the quality of the finished product.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1 to 9 A gear shaper, including a workbench 1, a mounting frame 2 is fixedly installed on the top wall of the workbench 1, a hydraulic rod 3 is installed on the mounting frame 2, an insertion tool 4 is provided on the hydraulic rod 3, a fixing component 8 for fixing the gear blank 12 is provided on the top wall of the workbench 1, and a cooling component 5 is provided on the workbench 1; The cooling component 5 includes a water cylinder 501 fixedly installed on the bottom wall of the workbench 1, a waste outlet 502 communicating with the water cylinder 501 is opened on the top wall of the workbench 1, a piston plate 503 is vertically slidably installed in the water cylinder 501, a vertical rod 504 fixedly connected to the insertion tool 4 is fixedly installed on the piston plate 503, a liquid inlet valve 505 with an output end downward is fixedly installed on the piston plate 503, a liquid discharge valve 506 is installed on the water cylinder 501, a water pipe 507 is fixedly installed on the output end of the liquid discharge valve 506, and a collection component 6 for collecting waste is provided on the workbench 1.

[0022] During use, the blank 12 is fixed by the fixing component 8, and then the output end of the hydraulic rod 3 is controlled to drive the cutting tool 4 to move downward to cut the blank 12. At the same time, during the downward movement of the cutting tool 4, the piston plate 503 is driven to move downward by the vertical rod 504. During the downward movement of the piston plate 503, the water flow below the piston plate 503 in the water cylinder 501 is squeezed and flows through the drain valve to the water pipe 507. Then the water flow flows through the water pipe 507 to the cutting area of the blank 12. When the water flow passes through the cutting area of the blank 12, it can drive the debris at the cutting area to move downward, thus avoiding the influence of debris on the cutting effect. At the same time, when the water flow passes through the cutting area, it can also cool the blank 12 and the cutting tool 4, thus avoiding the deformation of the blank 12 and the cutting tool 4 due to excessive temperature, which affects the quality of the finished product and plays a role in improving the quality of the finished product.

[0023] After cutting, the output end of the hydraulic rod 3 contracts and drives the cutting tool 4 to move upward. During the upward movement of the cutting tool 4, the piston plate 503 is driven to move upward. And during the upward movement of the piston plate 503, the space below the piston plate 503 in the water cylinder 501 absorbs water flow through the water inlet valve, which plays a role in preparing for the next operation.

[0024] As Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown in

[0025] A collecting box 601 is detachably installed on the bottom wall of the workbench 1. A collecting port communicating with the collecting box 601 is opened on the side wall of the waste port 502. A filter screen 602 for filtering waste is fixedly installed in the waste port 502.

[0026] A hollow rod 701 is rotatably installed on the workbench 1. A grinding disc 702 is fixedly installed on the top wall of the hollow rod 701. And a linkage groove 703 is opened on the grinding disc 702. A belt 704 is commonly installed between the hollow rod 701 and the annular plate 603.

[0027] By adopting the above technical solution, during the process of the water flow driving the debris to move downward, the filter screen 602 can block the debris in the water flow. At the same time, during the process of the inserting tool 4 driving the vertical rod 504 to move downward, the vertical rod 504 drives the convex block 607 to move downward along the vertical groove 606. And when the inserting tool 4 moves below the grinding disc 702, the convex block 607 contacts the spiral groove 605 and drives the annular plate 603 to rotate through the spiral groove 605. During the rotation of the annular plate 603, the scraping plate 604 is driven to rotate. Then, during the rotation of the scraping plate 604, the debris on the top wall of the filter screen 602 can be driven to rotate, and under the action of centrifugal force, the debris enters the collection box 601 through the collection port. Thus, it is unnecessary for the user to spend time cleaning the debris, and at the same time, it is avoided that the debris affects the normal water flow direction to the cutting part of the gear blank 12, further improving the finished product quality.

[0028] During the process of the inserting tool 4 cutting the gear blank 12, there will be burrs on the bottom wall of the gear blank 12. Then, during the rotation of the annular plate 603, the hollow rod 701 is driven to rotate through the belt 704. And during the rotation of the hollow rod 701, the grinding disc 702 is driven to rotate. Then, during the rotation of the grinding disc 702, the burrs on the bottom wall of the gear blank 12 can be processed, further improving the finished product quality of the gear blank 12.

[0029] When the inserting tool 4 moves upward, the vertical rod 504 drives the convex block 607 to move upward. And during the upward movement of the convex block 607, the hollow rod 701 is driven to reverse through the spiral groove 605. Then, during the reverse rotation of the hollow rod 701, the grinding disc 702 is driven to reverse through the belt 704 and the hollow rod 701, thereby further improving the grinding effect of the burrs of the gear blank 12 and the reset of the grinding disc 702 when the convex block 607 contacts the vertical groove 606. At this time, the linkage groove 703 on the grinding disc 702 contacts the cutting part of the gear blank 12, thus avoiding the linkage groove 703 from affecting the normal cutting of the gear blank 12.

[0030] As Figure 1 、 Figure 3 shown, the fixing component 8 includes a rotating rod 801 rotatably installed on the workbench 1, and the rotating rod 801 is rotationally matched with the hollow rod 701. The top end of the rotating rod 801 is fixedly installed with a three-jaw chuck 802 for fixing the gear blank 12. The bottom wall of the workbench 1 is fixedly installed with a stepping motor 803 whose output end is fixedly connected to the rotating rod 801.

[0031] A steel ball 804 matched with the three-jaw chuck 802 is fixedly installed on the top wall of the hollow rod 701.

[0032] By adopting the above technical solution, before cutting, the gear blank 12 is placed on the three-jaw chuck 802, and the gear blank 12 is fixed by the three-jaw chuck 802. Since the three-jaw chuck 802 is a relatively mature existing technology, it will not be described in detail here. When it is necessary to rotate the gear blank 12, the user can start the stepping motor 803, and then the stepping motor 803 drives the three-jaw chuck 802 to rotate through the rotating rod 801, and drives the gear blank 12 to rotate during the rotation of the three-jaw chuck 802, which plays a role in facilitating the rotation of the gear blank 12.

[0033] During the process of the hollow rod 701 driving the grinding disc 702 to grind the gear blank 12, by setting the steel balls 804, the friction between the hollow rod 701 and the three-jaw chuck 802 can be reduced, so as to ensure that the hollow rod 701 can normally drive the grinding disc 702 to grind the gear blank 12.

[0034] As Figure 6 、 Figure 8 As shown, a chute 901 is formed on the insert tool 4, a disc 902 is slidably installed in the chute 901, and the disc 902 is fixedly connected to the output end of the hydraulic rod 3. A rotating groove 903 is formed on the side wall of the chute 901, and a slider 904 slidably engaged with the rotating groove 903 is fixedly installed on the disc 902.

[0035] The surfaces of the convex block 607 and the slider 904 are both smooth mirror surfaces.

[0036] By adopting the above technical solution, during the process of the output end of the hydraulic rod 3 extending and driving the disc 902 to move downward along the chute 901, since the bottom wall of the insert tool 4 is connected to the piston plate 503 through the vertical rod 504 at this time, there is resistance when the insert tool 4 moves downward. Therefore, at this time, the disc 902 drives the slider 904 to slide along the rotating groove 903, and then the slider 904 drives the insert tool 4 to rotate through the rotating groove 903. When the side of the insert tool 4 with cutting teeth is directly above the gear blank 12, the bottom wall of the disc 902 contacts the bottom wall of the chute 901, and then the disc 902 drives the insert tool 4 to move downward through the chute 901, so as to ensure that the insert tool 4 normally cuts the gear blank 12. When the output end of the hydraulic rod 3 contracts and drives the disc 902 to move upward along the chute 901, the disc 902 drives the slider 904 to slide along the rotating groove 903 again, and makes the insert tool 4 reverse and reset. When the insert tool 4 drives the cutting teeth to be away from the gear blank 12, the top wall of the disc 902 contacts the top wall of the chute 901, and then the disc 902 drives the insert tool 4 to move upward through the chute 901, so as to avoid scratching the surface of the machined gear blank 12 during the reset process of the insert tool 4, reduce the wear of the gear shaper cutter, is beneficial to improving the gear processing quality, and at the same time can also improve the service life of the gear shaper cutter, and further improve the finished product quality.

[0037] When the bump 607 and the slider 904 slide along the spiral groove 605 and the rotary groove 903 respectively, by making the surfaces of the bump 607 and the slider 904 smooth mirror surfaces, the frictional forces received by the bump 607 and the slider 904 can be reduced, thereby ensuring that the bump 607 and the slider 904 can slide normally along the spiral groove 605 and the rotary groove 903 respectively.

[0038] As Figure 1 , Figure 2 shown, support rods 10 are symmetrically installed between the top wall of the workbench 1 and the mounting bracket 2.

[0039] Limit rods 11 that are slidably engaged with the piston plate 503 are symmetrically and fixedly installed on the inner bottom wall of the water cylinder 501.

[0040] By adopting the above technical solutions, by setting the support rods 10, the stress points of the mounting bracket 2 can be increased, thereby improving the stability during the cutting process, and by setting the limit rods 11, the piston plate 503 can be limited, so that the piston plate 503 can only slide vertically along the water cylinder 501, thereby preventing the vertical rod 504 from driving the piston plate 503 to rotate, playing a role in ensuring the normal operation of the device.

[0041] Usage method: During use, fix the gear blank 12 through the fixing component 8, then control the output end of the hydraulic rod 3 to drive the insert cutter 4 to move downward and cut the gear blank 12. At the same time, during the downward movement of the insert cutter 4, drive the piston plate 503 to move downward through the vertical rod 504. During the downward movement of the piston plate 503, the water flow below the piston plate 503 in the water cylinder 501 is squeezed and flows through the drain valve to the water pipe 507. Then the water flow flows through the water pipe 507 to the cutting area of the gear blank 12. When the water flow passes through the cutting area of the gear blank 12, it can drive the debris at the cutting area to move downward and can also cool the gear blank 12 and the insert cutter 4; during the process of the water flow driving the debris to move downward, the filter screen 602 can block the debris in the water flow. At the same time, during the process of the insert cutter 4 driving the vertical rod 504 to move downward, the vertical rod 504 drives the convex block 607 to move downward along the vertical groove 606. And when the insert cutter 4 moves below the grinding disc 702, the convex block 607 contacts the spiral groove 605 and drives the annular plate 603 to rotate through the spiral groove 605. During the rotation of the annular plate 603, drive the scraping plate 604 to rotate. Then during the rotation of the scraping plate 604, it can drive the debris on the top wall of the filter screen 602 to rotate, and under the action of centrifugal force, the debris enters the collection box 601 through the collection port; during the process of the insert cutter 4 cutting the gear blank 12, there will be burrs on the bottom wall of the gear blank 12. Then during the rotation of the annular plate 603, drive the hollow rod 701 to rotate through the belt 704. And during the rotation of the hollow rod 701, drive the grinding disc 702 to rotate. Then during the rotation of the grinding disc 702, it can process the burrs on the bottom wall of the gear blank 12; during the process of the output end of the hydraulic rod 3 extending and driving the disc 902 to move downward along the sliding groove 901, since the bottom wall of the insert cutter 4 is connected to the piston plate 503 through the vertical rod 504 at this time, there is resistance to the downward movement of the insert cutter 4. So at this time, the disc 902 drives the slider 904 to slide along the rotating groove 903. Then the slider 904 drives the insert cutter 4 to rotate through the rotating groove 903. And when the side of the insert cutter 4 with cutting teeth is directly above the gear blank 12, the bottom wall of the disc 902 contacts the bottom wall of the sliding groove 901. Then the disc 902 drives the insert cutter 4 to move downward through the sliding groove 901, so as to ensure that the insert cutter 4 normally cuts the gear blank 12. When the output end of the hydraulic rod 3 contracts and drives the disc 902 to move upward along the sliding groove 901, the disc 902 drives the slider 904 to slide along the rotating groove 903 again and makes the insert cutter 4 reverse and reset. And when the insert cutter 4 drives the cutting teeth away from the gear blank 12, the top wall of the disc 902 contacts the top wall of the sliding groove 901. Then the disc 902 drives the insert cutter 4 to move upward through the sliding groove 901, so as to avoid scratching the surface of the machined gear blank 12 during the reset process of the insert cutter 4 and reduce the wear of the gear shaper cutter.

[0042] As described above, it is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
