Description

Technical Field

[0001] The utility model relates to the technical field of gear processing devices, in particular to a fillet processing device for gear processing. Background Art

[0002] Gears are widely used mechanical transmission components, their primary function being to transmit power and motion. Gear teeth mesh with those of another gear, enabling power transmission and regulating speed and torque. During gear meshing, stress concentrates in the transition area between the tooth root and tooth top. Filleting can smooth the transition, reduce stress concentration, and prevent cracks in these areas.

[0003] When rounding a gear, the gear must first be secured. Typically, a keyed spindle is used, with the inner hole of the gear mating with the spindle, and the gear is then secured to the spindle with a key. However, this method is notoriously difficult to use, requiring the spindle to be replaced for each gear. Furthermore, to ensure gear stability during machining, a tight fit between the gear and the spindle is required, leading to significant resistance during both installation and removal, hindering gear machining efficiency.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0022] Examples, such as Figures 1 to 5 As shown, the present invention provides a device for processing rounded corners of gears, comprising a frame 1 and a gear 3 to be processed, mounted on the frame 1. A cutting component 2 is mounted on the frame 1. When rounding the corners of the gear 3, the cutting component is activated, causing a tool or a grinder to process the gear 3 according to a preset program. The tool or grinder moves along the contour of the tooth root or tooth top, removing material to form the rounded corners (this is prior art and will not be described in detail here).

[0023] This embodiment also includes a clamping and positioning component installed on the frame 1, and the clamping and positioning component includes an axis positioning assembly for positioning the axis of the gear 3 and a circumferential positioning mechanism for filling the keyway of the gear 3. The clamping and positioning component includes a plurality of support rods 4 fixedly installed on the frame 1, a load-bearing plate 401 fixedly installed on the top of the plurality of support rods 4, and a lifting plate 402 slidably installed on the plurality of support rods 4. Among them, the axis positioning assembly includes a plurality of slide grooves 403 provided on the load-bearing plate 401, a positioning rod 404 slidably installed in the slide grooves 403, a first connecting rod 405 fixedly installed on the positioning rod 404, the other end of the first connecting rod 405 is rotatably connected to the lifting plate 402, a hydraulic rod 406 is fixedly installed in the frame 1, and the output shaft of the hydraulic rod 406 is fixedly connected to the lifting plate 402. When fixing the gear 3, first place the gear 3 on the carrier plate 401, and make the axial center hole of the gear 3 located inside the multiple positioning rods 404. At this time, start the first hydraulic rod 406 to drive the lifting plate 402 to descend, and then drive the multiple first connecting rods 405 to synchronously descend and rotate. The transmission of the first connecting rod 405 can drive the multiple positioning rods 404 to move along the slide groove 403, and then drive the multiple positioning rods 404 to expand, so that the multiple positioning rods 404 are in contact with the axial center hole of the gear 3, and then drive the gear 3 to move. At the same time, the axis of the gear 3 and the axis of the circle formed by the multiple positioning rods 404 remain in a collinear position, and then the axis of the gear 3 can be positioned.

[0024] It should be noted that the plurality of slide grooves 403 are arranged in a circular array, and anti-slip grooves are rolled onto the positioning rods 404. The circular array of slide grooves 403 maintains the circular shape of the plurality of positioning rods 404, and the anti-slip grooves effectively increase the friction between the positioning rods 404 and the gear 3, thereby increasing the tightening force applied by the plurality of positioning rods 404 to the gear 3.

[0025] Furthermore, the circumferential positioning mechanism includes a slot 5 provided on the carrier plate 401, in which two guide rods 501 are fixedly installed, a slider 502 is slidably installed on the two guide rods 501, the slider 502 is provided with two connecting slots 503, and two positioning plates 504 are slidably installed in the connecting slots 503. The positioning plates 504 pass through the slider 502 and extend to the other side of the slider 502. An adjustment component for adjusting the distance between the two positioning plates 504 is installed on the slider 502. By adjusting the distance between the two positioning plates 504 through the distance adjustment component, the positioning plates 504 on both sides can be made to abut against the inner wall of the keyway of the gear 3, and the axial positioning of the gear 3 can be achieved through the cooperation between the keyway and the positioning plates 504. The two positioning plates 504 can be contracted and expanded, which can improve the scope of application and greatly improve the convenience of installing the gear 3, which is conducive to improving production efficiency.

[0026] The adjustment assembly includes a drive plate 505 fixedly mounted on the positioning plate 504. A second connecting rod 506 is rotatably mounted on the drive plate 505. A drive block 507 is rotatably mounted on the other ends of the two second connecting rods 506. A support base 509 is fixedly mounted on the slider 502. A second hydraulic rod 508 is fixedly mounted on the support base 509. The output shaft of the second hydraulic rod 508 is fixedly connected to the drive block 507. The second hydraulic rod 508 drives the drive block 507 to move up and down. This movement of the drive block 507 drives the second connecting rod 506 to rotate. The rotating second connecting rod 506 drives the two positioning plates 504 toward or away from each other, thereby adjusting the spacing between the two positioning plates 504 to ensure a tight fit between the positioning plates 504 and the notches of the gear 3. A third hydraulic rod 510 is fixedly mounted on the carrier plate 401. The output shaft of the third hydraulic rod 510 is fixedly connected to the slider 502. The third hydraulic rod 510 can drive the positioning plate 504 to fit tightly against the inner wall of the notch of the gear 3 .

[0027] The working principle of this embodiment is as follows: when fixing the gear 3, first place the gear 3 on the carrier plate 401, and make the axial center hole of the gear 3 located inside the multiple positioning rods 404. At this time, start the first hydraulic rod 406 to drive the lifting plate 402 to descend, and then drive the multiple first connecting rods 405 to synchronously descend and rotate. Through the transmission of the first connecting rod 405, the multiple positioning rods 404 can be driven to move along the slide groove 403, and then the multiple positioning rods 404 can be driven to expand, so that the multiple positioning rods 404 are in contact with the axial center hole of the gear 3, and then the gear 3 can be driven to move. At the same time, the axis of the gear 3 and the axis of the circle formed by the multiple positioning rods 404 remain in a collinear position, and then the axis of the gear 3 can be positioned. The second hydraulic rod 508 can drive the driving block 507 to perform lifting movements, and the driving block 507 that performs lifting movements can drive the second connecting rod 506 to rotate. The rotating second connecting rod 506 can drive the two positioning plates 504 to move closer to or away from each other, and then the distance between the two positioning plates 504 can be adjusted so that the positioning plates 504 and the slots of the gear 3 remain tightly fitted.

[0028] When rounding the gear 3, the cutting component is started so that the tool or grinding tool processes the gear 3 according to a preset program. The tool or grinding tool moves along the contour of the tooth root or tooth top to remove material and form a rounded corner.
