Description

Technical Field

[0001] This utility model relates to the field of thin-walled gear processing technology, specifically a worktable for cutting thin-walled gears. Background Technology

[0002] Thin-walled gears are prone to deformation during machining due to their thin walls and long shafts, making it difficult to ensure coaxiality. Therefore, tooling fixtures are often designed to facilitate the machining of parts on machine tools.

[0003] The existing Chinese utility model patent with publication number CN221363019U discloses a gear grinding workbench, including a main body, a platform, and a control console. The platform is fixedly installed on the top of the main body, and sliders are fixedly installed on both sides of the top of the platform. A sliding groove is movably installed on the outer wall of the slider, and the control console is fixedly installed on the outer wall of the sliding groove. A limiting groove is embedded in the top of the control console, and a clamping rod is movably installed inside the limiting groove. When a gear is placed on the clamping rod, the operator can rotate the handle to drive the clamping rod to move left and right through the transmission main rod, transmission gear wheel, driven gear, bidirectional threaded rod, linkage rod, and linkage groove. The middle of the clamping rod is confined inside the limiting groove. Therefore, when the linkage rod moves left and right, the clamping rod will move within the limiting groove and the linkage groove. At the same time, when the four clamping rods move inward or outward simultaneously, the size of the area enclosed by the four clamping rods also changes, thereby enabling the fixing of gears of different diameters.

[0004] When cutting thin-walled gears, there is a certain relative pressure between the tool and the gear. During the cutting process, the thin-walled gear may deform, affecting the quality of the finished product. At the same time, it is necessary to adjust the rotation angle of the gear during cutting in order to cut the tooth groove. Since the position of the gear needs to be fixed during cutting, it is very inconvenient to adjust the angle of the gear. Utility Model Content

[0009] As a preferred embodiment of this utility model, the two functional sides of the support frame are fixedly connected to the top surface of the base plate, the pressing piston is fixed directly above the base plate by the support frame, and the movable end of the pressing piston points vertically towards the base plate; the support frame can restrict the position of the pressing piston.

[0010] As a preferred embodiment of this utility model, the front end of the outer edge of the pressure plate is provided with a notch structure, and the center of the bottom surface of the pressure plate is provided with a cylindrical recess structure that fits into the connecting column. The pressure plate is located directly above the base. The pressure plate can prevent the gear from warping during the cutting of the thin-walled gear.

[0011] As a preferred technical solution of this utility model, the limiting plate is fixedly connected to the base plate through the limiting frame, and the front side of the limiting plate is provided with a groove structure that fits into the limiting block; the limiting plate can limit the position of the limiting block and support the gear.

[0012] As a preferred technical solution of this utility model, a toothed notch is provided on the front side of the center of the limiting block, and the limiting block and the limiting plate form a sliding connection; the limiting block can support the thin-walled gear on both sides of the cutting part.

[0013] As a preferred technical solution of this utility model, the bottom end of the base is provided with a columnar structure, and the columnar structure at the bottom end of the base penetrates the limiting plate, and the base and the limiting plate form a rotatable connection. The top end of the base is provided with a tubular protrusion, and the inner wall of the tubular protrusion at the top end of the base is provided with a threaded structure; the base can drive the thin-walled gear to rotate.

[0014] As a preferred embodiment of this utility model, the connecting column is a cylindrical structure with a closed top. A vertically downward cylindrical protrusion is provided at the center of the inner cavity of the connecting column, and a groove is provided on the outer side of the cylindrical protrusion structure inside the connecting column to be threadedly fitted into the inner wall of the tubular protrusion structure of the base. The bottom end of the base is fixedly connected to the rotating shaft of the stepper motor by an insertion method; the stepper motor can drive the base to rotate.

[0015] Compared with the prior art, the present invention provides a worktable for cutting thin-walled gears, which has the following advantages:

[0016] 1. This utility model features a base with a cylindrical structure at its bottom end that penetrates a limiting plate, forming a rotatable connection between the base and the limiting plate. A tubular protrusion is located at the top of the base, with a threaded structure on its inner wall. The bottom end of the base is fixedly connected to the stepper motor shaft via an insertion method. The connecting column is a closed-top cylindrical structure with a vertically downward cylindrical protrusion at the center of its inner cavity. The outer surface of the cylindrical protrusion inside the connecting column is designed to connect with the tubular protrusion of the base. The groove with inner thread engagement allows the protruding structure at the top of the base to pass through the thin-walled gear in an interlocking manner, positioning the thin-walled gear directly above the base. Then, the connecting column is installed on the top of the base by rotation. The protruding structure at the center of the connecting column will connect to the base through a threaded structure. As the connecting column moves downward with rotation, the bottom end of the outer wall of the connecting column will clamp the thin-walled gear with the base. This method allows the thin-walled gear above the base to rotate synchronously with the base when the stepper motor drives the base to rotate, facilitating the adjustment of the rotation angle of the thin-walled gear.

[0017] 2. This utility model features a pressure plate that is fixedly installed at the bottom of a lower piston. The lower piston is fixed above the base by a support frame, with its movable end pointing towards the base plate. The front end of the outer edge of the pressure plate has a notch structure, and the center of the bottom surface of the pressure plate has a cylindrical recess structure that fits into the connecting column. After the thin-walled gear is fixed and before cutting, the lower piston drives the pressure plate downward, so that the bottom surface of the pressure plate contacts the top surface of the thin-walled gear, and there is a certain relative pressure between the thin-walled gear and the pressure plate, the limiting plate, and the limiting block. Since the center front side of the limiting block has a toothed notch, the tool can perform toothed cutting on the thin-walled gear through the notch of the limiting block and the pressure plate. This method can restrict the pressure on the upper and lower sides of the thin-walled gear during the cutting process to resist the stress generated during cutting, thereby preventing the thin-walled gear from warping during cutting.

The pressing piston 12 is fixed directly above the base plate 1 via the support frame 11, with the movable end of the pressing piston 12 pointing vertically towards the base plate 1. The front end of the outer edge of the pressure plate 13 is provided with a notch structure, and the center of the bottom surface of the pressure plate 13 is provided with a cylindrical recess structure that fits into the connecting column 18.

The front side of the limiting plate 15 is provided with a groove structure that fits into the limiting block 16. The front side of the center of the limiting block 16 is provided with a toothed notch. The limiting block 16 and the limiting plate 15 are connected. A sliding connection is formed. The bottom end of the base 17 is provided with a columnar structure, and the columnar structure at the bottom end of the base 17 penetrates the limiting plate 15. The base 17 and the limiting plate 15 are rotatably connected. The top end of the base 17 is provided with a tubular protrusion. The inner wall of the tubular protrusion at the top end of the base 17 is provided with a threaded structure. The connecting column 18 is a cylindrical structure with a closed top end. The center of the inner cavity of the connecting column 18 is provided with a vertically downward columnar protrusion. The outer side of the columnar protrusion structure inside the connecting column 18 is provided with a groove that is threadedly engaged with the inner wall of the tubular protrusion structure of the base 17. The bottom end of the base 17 is fixedly connected to the rotating shaft of the stepper motor 110 by insertion.

[0028] Specifically, the base plate 1 supports the stepper motor 110, the support frame 11 restricts the position of the pressing piston 12, the pressing piston 12 drives the pressure plate 13 to move downward, the pressure plate 13 prevents the gear from warping during the cutting of the thin-walled gear, the limiting frame 14 supports the limiting plate 15, the limiting plate 15 restricts the position of the limiting block 16 and supports the gear, the limiting block 16 supports the thin-walled gear on both sides of the cutting part, the base 17 drives the thin-walled gear to rotate, the connecting column 18 restricts the thin-walled gear above the base 17, the rubber pad 19 protects the outer edge of the thin-walled gear, and the stepper motor 110 drives the base 17 to rotate.

[0029] In use, the base 17 has a columnar structure at its bottom end, which penetrates the limiting plate 15, forming a rotatable connection between the base 17 and the limiting plate 15. The top end of the base 17 has a tubular protrusion with a threaded structure on its inner wall. The bottom end of the base 17 is fixedly connected to the shaft of the stepper motor 110 via an insertion method. The connecting column 18 is a cylindrical structure with a closed top. A vertically downward-pointing columnar protrusion is located at the center of the inner cavity of the connecting column 18. The outer surface of the structure is provided with a groove that threadedly engages with the inner wall of the tubular protrusion of the base 17. The protrusion at the top of the base 17 is inserted through a thin-walled gear, positioning the thin-walled gear directly above the base 17. Then, the connecting post 18 is installed on the top of the base 17 by rotation. The protrusion at the center of the connecting post 18 is connected to the base 17 via a threaded connection. As the connecting post 18 rotates downwards, the bottom end of its outer wall clamps the thin-walled gear with the base 17. This method allows the stepper motor 1... When the base 17 rotates, the thin-walled gear above the base 17 rotates synchronously with the base 17 to facilitate adjustment of the rotation angle of the thin-walled gear.

The front end of the outer edge of the pressure plate 13 is provided with a notch structure, and the center of the bottom surface of the pressure plate 13 is provided with a cylindrical recess structure that fits into the connecting column 18. After the thin-walled gear is fixed and before cutting, the pressing piston... 12 drives the pressure plate 13 to move downward, so that the bottom surface of the pressure plate 13 contacts the top surface of the thin-walled gear, and there is a certain relative pressure between the thin-walled gear, the pressure plate 13, the limiting plate 15, and the limiting block 16. Since the center front side of the limiting block 16 is provided with a toothed notch, the tool can perform toothed cutting on the thin-walled gear through the notch of the limiting block 16 and the pressure plate 13. This method can limit the pressure on the upper and lower sides of the thin-walled gear during the cutting process to resist the stress generated during cutting, thereby avoiding the warping of the thin-walled gear during cutting.
