Description

Technical Field

[0001] The present invention relates to the technical field of face gear processing, and particularly to a machine tool for face gear processing. Background Technique

[0002] A face gear is a gear that mates with a spur gear or a helical gear at a 90-degree shaft intersection angle. Among them, the two perpendicular central axes of the pinion and the face gear can intersect or have an offset distance; it is mainly applied to industries such as helicopters, fishing reels, watches, and bicycles. Its heavy-load and stable transmission characteristics have a relatively wide application space.

[0003] When processing a relatively large face gear, it is usually formed by blank forging, and it is necessary to position and press the ring-shaped workpiece. A machine tool for face gear processing with the patent publication number of CN116393639B includes a machine tool body, a driving device, a limiting device, an outer wall notch forging device, and a forging device. Among them, the outer wall notch forging device includes an arc plate and a forging ball, and the forging assembly includes a forging plate, a plurality of outer forging rollers, a movable forging roller, and a clamping assembly.

[0004] When the above device works, the clamping assembly in the limiting device and the forging device clamps and limits the ring-shaped gear embryo, and the inner side and the outer side of the ring-shaped workpiece are limited by the outer forging roller and the movable forging roller. Furthermore, when the outer wall notch forging device rotates, the forging ball is in close contact with the outer side of the gear workpiece through the arc plate with a resilient pressing effect, and a grooving process is carried out.

[0005] However, when the above device clamps and feeds the gear workpiece, the arc plate has a resilient pressing effect. Therefore, without external force, the positions of the arc plate and the forging ball may cause a certain blockage or hindrance to the workpiece, affecting the feeding and limiting of the workpiece; and the position adaptation range of the forging ball is small, resulting in a small change range of the sizes of the gears that the machine tool can process.

[0006] Based on this, the present invention designs a machine tool for face gear processing to solve the above problems. Summary of the Invention

[0048] Embodiment 1

[0049] Please refer to the accompanying drawings. The present invention provides a technical solution:

[0050] It includes a fixed seat 100 and a top plate 205 located above the fixed seat 100. Symmetrically arranged on the left and right sides of the fixed seat 100 are moving grooves 200. Moving components are provided in the moving grooves 200 and are connected to the top plate 205 through two moving components. Below the top plate 205, a lifting plate 207 is commonly connected by two hydraulic telescopic rods 206. Symmetrically and rotatably connected to the left and right of the lower part of the lifting plate 207 are two upper pressing rollers 208;

[0051] In the middle of the top surface of the fixed seat 100 is provided a cylindrical fixed box 104. Along the circumferential direction of the outside of the fixed box 104, a plurality of vertical side plates 101 are evenly fixed. Between the front and rear two side plates 101 and the fixed box 104 is rotatably connected a support roller 103. Between the left and right two side plates 101 and the fixed box 104 is rotatably connected a lower pressing roller 102. The support roller 103 and the lower pressing roller 102 have the same structure. The outer end of the lower pressing roller 102 is connected to a motor, and the lower pressing roller 102 is located below the upper pressing roller 208. The roller surfaces of the upper pressing roller 208 and the lower pressing roller 102 are both provided with conical surfaces, and the bottoms of the upper pressing roller 208 and the lower pressing roller 102 are kept horizontal, with the central axes inclined, so that the workpiece can be kept horizontal under the action of the upper pressing roller 208 and the lower pressing roller 102 and rotate along the circumferential direction;

[0052] Four inner rollers 300 are evenly arranged along the circumferential direction of the outside of the fixed box 104, and the positions of the inner rollers 300 are staggered from those of the support roller 103 and the lower pressing roller 102. The top and bottom ends of the inner rollers 300 are respectively rotatably connected to telescopic plates 301. The telescopic plates 301 are arranged along the radial direction of the fixed box 104, and the inner ends extend into the fixed box 104 and are connected to telescopic components;

[0053] The bottom surface of the fixed seat 100 is evenly provided with two first sliding grooves 401 and two second sliding grooves 501 along the circumferential direction, and the first sliding grooves 401 and the second sliding grooves 501 are arranged at intervals. A first slider 402 is connected in the first sliding groove 401 through a first adjusting component. A vertical first outer roller 400 is rotatably connected to the first slider 402. A second slider 502 is connected in the second sliding groove 501 through a second adjusting component. A vertical second outer roller 500 is rotatably connected to the second slider 502. A forming convex ring 600 is provided on the upper part of the second outer roller 500.

[0054] When machining a gear workpiece, place the annular workpiece on the lower pressing roller 102 and the supporting roller 103, and then adjust the positions of the four inner rollers 300 through the telescopic component. Adjust the position of the annular workpiece through the four inner rollers 300 to make it centered and determine its position. Then adjust the positions of the two first outer rollers 400 through the first adjusting component to make them contact the outer side edge of the annular workpiece. Adjust the position of the second outer roller 500 through the second adjusting component to make the forming convex ring 600 on it contact the outer side wall of the workpiece.

[0055] Start the hydraulic telescopic rod 206 to drive the lifting plate 207 to drive the upper pressing roller 208 to move downward, so that the upper pressing roller 208 tightly presses on the top of the annular workpiece. Thus, the upper and lower sides of the annular workpiece are tightly pressed by the upper pressing roller 208 and the lower pressing roller 102, and drive the lower pressing roller 102 through the motor to make the annular workpiece rotate accordingly.

[0056] During the rotation process, continuously adjust the positions of the second outer roller 500 and the forming convex ring 600 inward through the second adjusting component to press the side edge of the annular workpiece, and gradually adjust the positions of the first outer roller 400 and the inner roller 300 according to the processing requirements to keep the inner side edge and the outer side edge of the annular workpiece at the corresponding radius positions, and keep the annular workpiece at an appropriate thickness through the upper pressing roller 208 and the lower pressing roller 102, avoiding deformation of the remaining positions of the annular workpiece due to side pressing, improving the processing effect, and being able to flexibly adjust the positions of each side roller and pressing roller according to the processing requirements.

[0057] Among them, the telescopic component includes a vertical worm 306 rotatably connected to the center of the fixed box 104. Four worm wheels 304 are evenly meshed with the worm 306 along the circumferential direction. The worm wheels 304 are rotatably connected to the fixed box 104 and coaxially fixed with third gears 305. Tooth grooves are provided on the opposite side surfaces of the two telescopic plates 301 on the same inner roller 300, and a plurality of teeth are evenly fixed along the length direction of the tooth grooves. And the telescopic plate 301 is meshed with a first gear 302 through the teeth. A second gear 303 is jointly meshed between the first gear 302 and the corresponding third gear 305, and both the first gear 302 and the second gear 303 are rotatably connected to the fixed box 104.

[0058] When it is necessary to adjust the position of the inner roller 300, the worm 306 is driven by a motor, and through the transmission of the worm 306 and the worm gear 304, as well as the transmission of the first gear 302, the second gear 303 and the third gear 305, the plurality of telescopic plates 301 drive the corresponding inner rollers 300 to move simultaneously, realizing the synchronous adjustment of the four inner rollers 300.

[0059] Among them, the first adjustment component includes a first screw rod 403 rotatably connected to the first chute 401. The first screw rod 403 is threadedly connected to the first slider 402. The inner end of the first screw rod 403 extends into the fixed box 104 and is fixed with a first bevel gear 404. A first bevel gear ring 405 is rotatably connected to the bottom of the worm 306. Both first bevel gears 404 are engaged with the first bevel gear ring 405. And a first driving bevel gear 406 is also engaged with one side of the first bevel gear ring 405. The first driving bevel gear 406 is connected to a motor. By driving the first driving bevel gear 406 with the motor and through the transmission of the first bevel gear ring 405 and the first bevel gear 404, the two first screw rods 403 are rotated to adjust the position of the first side roller.

[0060] Among them, the second adjustment component includes a second screw rod 505 rotatably connected to the second chute 501. The second screw rod 505 is threadedly connected to the second slider 502. The inner end of the second screw rod 505 extends into the fixed box 104 and is fixed with a second bevel gear 506. The second bevel gear 506 is located outside the two first bevel gears 404 so that the second bevel gear 506 and the second bevel gear 506 are staggered with the first bevel gear ring 405 and the first bevel gear 404 in position. A rotating plate 503 is rotatably connected to the lower part of the worm 306. A second bevel gear ring 504 is fixed to the bottom of the rotating plate 503. Both second bevel gears 506 are engaged with the second bevel gear ring 504. And a second driving bevel gear 507 is also engaged with one side of the second bevel gear ring 504. The second driving bevel gear 507 is connected to a motor. By driving the second driving bevel gear 507 with the motor and through the transmission of the second bevel gear ring 504 and the second bevel gear 506, the two second screw rods 505 are rotated to adjust the positions of the second side roller and the forming convex ring 600.

[0061] Among them, the moving component includes a moving seat 202 slidably connected to the moving groove 200. A moving screw rod 201 is threadedly connected in the moving groove 200.

An inclined reinforcing rod 204 is fixed between the front side of the fixing frame 203 and the front side section of the top of the moving seat 202. By driving the moving screw rod 201 with the motor, the rotation of the moving screw rod 201 drives the movement of the moving seat 202 and the fixing frame 203, realizing the movement of the top plate 205 and the upper pressing roller 208.

[0062] Embodiment 2

[0063] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that a material supporting plate 700 is provided above the fixed seat 100. The material supporting plate 700 is located below the supporting roller 103 and the lower pressing roller 102, and a concave first roller groove 706 is provided corresponding to the positions of the supporting roller 103 and the lower pressing roller 102. A plurality of vertical spring rods 701 are uniformly fixed to the bottom of the material supporting plate 700. A vertical spring cylinder 702 is provided on the top of the fixed seat 100. The spring rods 701 are slidably connected in the spring cylinder 702 and are connected with springs.

[0064] Two push blocks 704 are symmetrically provided on both sides of the bottom of the fixed seat 100. Two connecting rods 703 are rotatably connected to the top of each push block 704, and the top ends of the connecting rods 703 are rotatably connected to the corresponding sides of the bottom of the material supporting plate 700. A cavity is provided inside the fixed seat 100, and a transmission component is provided in the cavity. The transmission component is correspondingly connected to the moving seat 202. A vertical push shaft 705 is rotatably connected to the bottom of the push block 704. An axial groove 109 is provided on the top of the fixed seat 100 along the radial direction. The bottom end of the push shaft 705 passes through the axial groove 109 and is correspondingly connected to the rotating component.

[0065] When the moving seat 202 and the upper pressing roller 208 are far away from the fixed seat 100, the material supporting plate 700 is higher than the supporting roller 103 and the lower pressing roller 102, so as to separate the processed workpiece from the supporting roller 103 and the lower pressing roller 102, and stagger the height position from the inner roller 300, the first outer roller 400 and the second outer roller 500, facilitating blanking through an external device and reloading; after reloading, the moving seat 202 and the upper pressing roller 208 return to their positions, the upper pressing roller 208 returns above the lower pressing roller 102, and while the moving seat 202 moves, the transmission assembly drives the push shaft 705 to drive the push block 704 to move along the shaft groove 109, so that the connecting rod 703 drives the material supporting plate 700 to drive the spring rod 701 to move down along the spring cylinder 702, and then the workpiece falls onto the supporting roller 103 and the lower pressing roller 102, and the material supporting plate 700 is separated from the workpiece, so that during the reciprocating movement of the moving seat 202, through the cooperation of the transmission assembly, the feeding and blanking of the workpiece are realized.

[0066] Inner concave second roller grooves 707 are provided at the corresponding positions of the inner side and the outer side of the material supporting plate 700 for each of the first outer roller 400, the second outer roller 500 and the inner roller 300, so as to increase the movable range of the first outer roller 400, the second outer roller 500 and the inner roller 300 and improve the applicable range of roll forming.

[0067] Embodiment III

[0068] The structure of this embodiment is basically the same as that of Embodiment II, the difference being that the transmission assembly includes a circular table 105 fixed at the center of the inner cavity of the fixed seat 100, a rotating disk 106 is rotatably connected to the circular table 105, a transmission gear ring 107 is fixed on the outer side of the rotating disk 106, a moving rack 209 is fixed on one side of the moving seat 202 close to the fixed seat 100, through grooves are provided on the side walls of the moving groove 200 and the fixed seat 100, and the moving rack 209 is meshed with the transmission gear ring 107 through the through grooves, a plurality of push grooves 108 are uniformly arranged on the rotating disk 106, the push grooves 108 are inclined relative to the radius of the rotating disk 106, and the bottom end of the push shaft 705 passes through the shaft groove 109 and extends into the corresponding push groove 108.

[0069] When the top plate 205 of the moving seat 202 is located above the middle of the fixed seat 100, the height of the material supporting plate 700 is lower than that of the supporting roller 103 and the pressing roller 102. When the moving seat 202 moves backward, the driving gear ring 107 is driven by the rack to drive the rotating disk 106 to rotate. Thus, under the action of the pushing groove 108, the pushing shaft 705 moves along the shaft groove 109, and drives the pushing block 704 to move. Then, the material supporting plate 700 is lifted along the spring cylinder 702 through the pushing block 704 and the connecting rod 703, so that the workpiece on the supporting roller 103 and the pressing roller 102 is jacked up, separated from the supporting roller 103 and the pressing roller, and the height positions of the workpiece are staggered from those of the inner roller 300, the first outer roller 400 and the second outer roller 500, which is convenient for blanking through an external device or the like.

[0070] Then, after reloading, the moving seat 202 drives the upper pressing roller 208 to move above the middle of the fixed seat 100. At the same time, under the action of the moving rack 209 and the driving gear ring 107, the rotating disk 106 rotates back, and then the material supporting plate 700 drives the workpiece to move down, so that the workpiece falls onto the pressing roller 102 and the supporting roller 103 for subsequent processing.

[0071] When the pushing plate moves up and down, through the arranged first roller groove 706, the material supporting plate 700 is prevented from contacting the pressing roller 102 and the supporting roller 103.

[0072] Embodiment 4

[0073] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that a vertical adjusting groove 508 is arranged at the position corresponding to the forming convex ring 600 on the upper part of the second outer roller 500. An adjusting block 601 is slidably connected in the adjusting groove 508. Both ends of the adjusting block 601 are fixedly connected to the inner side wall of the forming convex ring 600.
