Description

Technical Field

[0001] This invention relates to the field of gear processing equipment technology, specifically to an integrated lightweight gear processing equipment. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. There are many ways to manufacture gears, including casting, sintering, milling, etc. Among them, metal gears are usually manufactured by milling.

[0003] Besides the tooth grooves, common gears also feature recesses on both sides and a through hole around the center; these are examples of lightweight gear manufacturing. Lightweight gear manufacturing aims to reduce gear weight for better transmission and to allow more lubricant to flow through during operation.

[0004] Existing gear lightweighting processes involve fragmented steps. For example, milling the grooves on both sides of the gear, milling the gear tooth grooves, and chiseling the through holes are done in separate steps. Typically, the steel billet is first cut into a steel column, then the two sides of the steel column are milled in steps, then it is taken out and a drilling machine is used to drill a hole in the middle, and finally it is taken out to a gear cutting machine to chisel a ring of tooth grooves on the outer ring. This step-by-step processing method is not only cumbersome and requires a lot of manual operation, but the time consumed in the step-by-step processing of the gear may also cause deformation of the gear due to the cooling after being heated during processing or installation errors. Ultimately, complex finishing is required to adjust the dimensions, resulting in a decrease in processing efficiency. Summary of the Invention

[0005] This invention provides an integrated lightweight gear processing equipment, which automatically feeds a steel column onto an arc-shaped guide rail and automatically clamps it during the arc-shaped displacement of the steel column to two processing stations, thereby completing the integrated lightweight processing of the gear.

It solves the problem mentioned in the background art that the existing lightweight gear processing methods involve scattered steps. This step-by-step processing method is not only cumbersome and requires a lot of manual operation, but the time consumed in the step-by-step processing of the gear may also cause deformation of the gear due to heat and cooling during processing or installation errors, resulting in a decrease in processing efficiency.

[0031] The present invention has the following beneficial effects:

[0032] 1. This integrated lightweight gear machining equipment, while the steel column moves along the arc-shaped guide rail, has two workstations on the left and right, interleaving to complete the basic gear machining process, including the initial tooth groove cutting on one ring and the drilling of mounting holes in the middle, as well as the lightweight machining process of milling grooves on both sides and drilling several through holes in the middle ring. By machining the steel column as a whole, the level of automation is improved, labor consumption is reduced, and processing efficiency is greatly increased. Furthermore, it reduces the problem of large dimensional errors in the finished gear workpiece caused by thermal deformation and installation errors during the traditional step-by-step machining process.

[0033] 2. In this integrated lightweight gear processing equipment, during the automatic upward feeding of the steel column, when the steel column is fed into the moving frame, it pushes aside several support blocks that form a support ring and enters the moving frame. These support blocks then reset under spring pressure, reforming the support ring to support the steel column, thus causing the steel column to move in an arc shape with the moving frame. During this arc-shaped movement, upon reaching the left and right workstations, the support blocks retract into the moving frame under the guidance of several sets of connecting rods and the second arc-shaped grooves whose radius expands to both sides, thereby preventing the support blocks from interfering with the processing at the workstations.

[0034] 3. In this integrated lightweight gear processing equipment, as the steel column moves in an arc shape to both sides along the moving frame, the rolling of the spur gear along the arc-shaped rack and the transmission action of the one-way transmission component cause several grippers to slide along the trajectory of several first arc-shaped grooves from the beginning to the middle, thereby clamping the steel column for processing. When moving to the second station, the grippers are held in place by the limiting of the one-way transmission. When transferring to the unloading position at the second station, the grippers slide along the middle of the several first arc-shaped grooves to the end, releasing the steel column.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] To achieve integral machining of the steel column 100, basic machining is performed by opening a toothed groove 120 around its perimeter, opening a mounting hole 130 for connecting shaft in the middle, and lightweight machining is performed by opening grooves 110 on both sides and opening a through hole 140 around the middle, thereby improving machining efficiency. Example 1 is proposed.

[0049] Please see Figures 1-8An integrated lightweight gear processing equipment includes a steel column 100 and a base 200. The steel column 100 is provided with a tooth groove 120, a mounting hole 130, two grooves 110 and several through holes 140. The base 200 is provided with a housing 210, and an arc-shaped guide rail 220 is provided on the housing 210. A movable frame 230 is provided in the middle of the arc-shaped guide rail 220.

[0050] A loading and unloading mechanism 300 is provided on the base 200 at the middle position of the arc-shaped guide rail 220. The loading and unloading mechanism 300 is used to feed the steel column 100 into the movable frame 230 and complete the unloading.

[0051] The base 200 is provided with a tooth-cutting mechanism 500, a drilling mechanism 600 and two milling mechanisms 400. The tooth-cutting mechanism 500 and one of the milling mechanisms 400 are located on one side of the arc-shaped guide rail 220, and the drilling mechanism 600 and the other milling mechanism 400 are located on the other side of the arc-shaped guide rail 220.

[0052] The base 200 is also provided with a first drive component 240 connected to the movable frame 230. The first drive component 240 drives the movable frame 230 to slide along the arc guide rail 220 to both sides of the arc guide rail 220 for processing.

[0053] The first drive assembly 240 includes a first motor 241 disposed on the base 200, and a fourth connecting rod 242 slidably disposed on the housing 210. One end of the fourth connecting rod 242 is connected to the movable frame 230, and the other end of the fourth connecting rod 242 is connected to the output shaft of the first motor 241.

[0054] The loading and unloading mechanism 300 includes a feeding channel 310 disposed on the housing 210, and the feeding channel 310 is configured as a funnel with its tip aligned with the moving frame 230.

[0055] The loading and unloading mechanism 300 also includes a first cylinder 320 disposed on the base 200 and a second cylinder 330 disposed on the housing 210, and the output shafts of the first cylinder 320 and the second cylinder 330 are both aligned with the moving frame 230.

[0056] The milling mechanism 400 includes a first mounting base 410 slidably disposed on the base 200, a first turntable 420 rotatably disposed on the first mounting base 410, a second motor 430 disposed inside the first mounting base 410, and the output shaft of the second motor 430 connected to the first turntable 420.

[0057] A milling cutter 440 is provided on the first turntable 420 at an off-center position, and a third cylinder 450 is provided on the base 200, with the output shaft of the third cylinder 450 connected to the first mounting base 410.

[0058] The tooth-cutting mechanism 500 includes a second mounting base 510 slidably disposed on the base 200, a second turntable 520 rotatably disposed on the second mounting base 510, a tooth-cutting cutter 530 disposed on the second turntable 520 at an off-center position, and a third motor 540 disposed inside the second mounting base 510, the output shaft of the third motor 540 being connected to the second turntable 520.

[0059] A fourth motor 550 is installed on the base 200, a third turntable 560 is installed on the output shaft of the fourth motor 550, and a connecting column 570 is installed on the third turntable 560 off-center.

[0060] The tooth-cutting mechanism 500 also includes a fifth connecting rod 580, the two ends of which are respectively hinged to the second mounting base 510 and the connecting column 570;

[0061] The drilling mechanism 600 includes a third mounting base 610 slidably disposed on the base 200. The third mounting base 610 is provided with a first drilling machine 620 and a plurality of second drilling machines 630. The base 200 is provided with a fourth cylinder 640, and the output shaft of the fourth cylinder 640 is connected to the third mounting base 610.

[0062] In this embodiment: After the steel column 100 is placed on the first cylinder 320, the first cylinder 320 is operated to feed the steel column 100 upward. The steel column 100 is fed into the straight cylinder at the top of the feeding channel 310 through the funnel-shaped feeding channel 310 on the lower side, and then fed upward into the moving frame 230.

[0063] The first motor 241, which is mounted on the base 200, drives the fourth connecting rod 242, which is fixed to its output shaft, to slide along the arc-shaped groove on the front side of the housing 210. The fourth connecting rod 242 then drives the movable frame 230, which is fixed to it, to slide along the arc-shaped guide rails 220 set on both sides of the inner side of the housing 210.

[0064] The movable frame 230 first slides to the left side of the arc-shaped guide rail 220, reaching the milling mechanism 400 and the gear-cutting mechanism 500. Then, the milling mechanism 400 and the gear-cutting mechanism 500 can operate simultaneously or in stages. The third cylinder 450, mounted on the base 200, operates, driving the first mounting seat 410, which is fixed to its output shaft, to move towards the steel column 100. During the movement, the second motor 430 installed in the first mounting seat 410 operates, driving the first turntable 420, which is coaxially fixed to its output shaft, to rotate. The first turntable 420 then drives the milling cutter 440, which is fixed to its circumferential edge, to rotate. The milling cutter 440 performs high-speed circular motion as it moves towards the steel column 100, thereby milling a groove 110 on one side of the steel column 100.

[0065] The fourth motor 550, mounted on the base 200, operates, driving the third turntable 560, which is coaxially fixed with its output shaft, to rotate. The third turntable 560 then drives the connecting column 570, which is fixed at its circumferential edge, to rotate, causing the fifth connecting rod 580 to drive the second mounting base 510 to slide back and forth on the base 200. This causes the second turntable 520 to move back and forth along the edge of the steel column 100 for milling. At the same time, during the milling process, the third motor 540 is intermittently operated, causing the toothed cutter 530 to move around the circumference of the steel column 100, thereby creating a toothed groove 120 on the steel column 100.

[0066] Similarly, the first motor 241 drives the moving frame 230 to move the steel column 100 to the right. The drilling mechanism 600 and another milling mechanism 400 operate synchronously or in stages to mill a groove 110 on the other side of the steel column 100. The fourth cylinder 640, mounted on the base 200, moves the third mounting base 610 towards the steel column 100. Simultaneously, the first drilling rig 620 and several second drilling rigs 630, mounted on the third mounting base 610, operate. The first drilling rig 620, located in the center, drills a mounting hole 130, and several second drilling rigs 630, equidistantly distributed around the first drilling rig 620, drill several through holes 140.

[0067] After the steel column 100 is processed into a lightweight gear, the first motor 241 moves the moving frame 230 back to its original position. The second cylinder 330 installed on the housing 210 then pushes the steel column 100 downward away from the moving frame 230 to complete the unloading.

[0068] It should be further explained that an additional belt conveyor mechanism can be added between the feeding channel 310 and the first cylinder 320. This belt conveyor transports the steel column 100 to the upper side of the first cylinder 320. Two first cylinders 320 can be added at this time, positioned on either side of the steel column 100. The two first cylinders 320 operate to lift the steel column 100 upwards and feed it into the feeding channel 310, then continue lifting it into the moving frame 230. Afterwards, the second cylinder 330 operates to push the steel column 100 back onto the belt and transport it back. This can further improve the automation level of the device.

[0069] Furthermore, the milling mechanism 400, the gear-cutting mechanism 500, and the drilling mechanism 600 are all conventional and mature existing technologies. During the milling and drilling process, a lubricant injection mechanism and a coolant injection mechanism can be added to prevent the metal from overheating and deforming during processing.

[0070] Example 2

[0071] In order to enable the steel column 100 to be automatically clamped for milling, drilling and toothing as the moving frame 230 moves along the arc guide rail 220, and to be automatically released when the steel column 100 returns to the middle position of the arc guide rail 220 after the final processing is completed, so that the steel column 100 can be unloaded by the second cylinder 330, Embodiment 2 is proposed.

[0072] This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figures 3-10 The movable frame 230 is also provided with a clamping mechanism 700 for fixing the steel column 100. The clamping mechanism 700 includes a slide block 710 slidably disposed in the movable frame 230. The slide block 710 is circumferentially equidistantly provided with a plurality of grippers 720 for clamping the steel column 100.

[0073] The movable frame 230 is rotatably provided with a rotating seat 730. The rotating seat 730 is provided with several first arc-shaped grooves 740 in the circumferential direction. A first connecting rod 750 is slidably provided in each of the several first arc-shaped grooves 740, and several grippers 720 are slidably connected to the several first connecting rods 750 respectively.

[0074] The clamping mechanism 700 also includes a second drive assembly 760 connected to the rotary table 730, which drives the rotary table 730 to rotate unidirectionally when the moving frame 230 slides to both sides of the arc-shaped guide rail 220.

[0075] The second drive assembly 760 includes a first bevel gear 761 disposed on the rotary seat 730, a first rotating rod 762 rotatably disposed on the moving frame 230, and a second bevel gear 763 disposed on the first rotating rod 762 that meshes with the first bevel gear 761.

[0076] The first rotating rod 762 is connected to a spur gear 764 through a one-way transmission assembly 766. The housing 210 is provided with an arc-shaped rack 765 that meshes with the spur gear 764. One-way transmission between the spur gear 764 and the first rotating rod 762 is realized through the one-way transmission assembly 766.

[0077] The one-way transmission assembly 766 includes a mounting plate 7661 rotatably mounted on the movable frame 230, a second rotating rod 7662 mounted on the mounting plate 7661, and a spur gear 764 mounted on the second rotating rod 7662;

[0078] The first rotating rod 762 is equipped with a ratchet 7663, and the mounting plate 7661 is rotatably equipped with a pawl 7664 that meshes with the ratchet 7663. The mounting plate 7661 is also equipped with a spring plate 7665, which presses the pawl 7664 onto the ratchet 7663.

[0079] In this embodiment: First, during the operation of the first motor 241 driving the moving frame 230 to move to the left in an arc shape, the spur gear 764 is driven to rotate by the arc rack 765 due to meshing with it. The spur gear 764 then drives the second rotating rod 7662 and the mounting plate 7661 to rotate. At this time, the two pawls 7664 mounted on the mounting plate 7661 rotate in a circular motion in the opposite direction to the direction of the teeth of the ratchet 7663. The pawls 7664 mesh with the ratchet 7663, driving the ratchet 7663 and the first rotating rod 762 to rotate.

[0080] The first rotating rod 762 drives the second bevel gear 763 to rotate, and the second bevel gear 763 drives the first bevel gear 761 and the rotating seat 730 to rotate. The rotating seat 730 rotates, causing several first arc-shaped grooves 740 to make circular motion. The first arc-shaped groove 740 is a semicircle, and its convex part is aligned with the center of the rotating seat 730. The central axis of the first arc-shaped groove 740 coincides with the radius of the rotating seat 730. When the moving frame 230 is located in the middle of the arc-shaped guide rail 220, the first connecting rod 750 is located at the arc-shaped head end of the first arc-shaped groove 740.

[0081] Several first arc-shaped grooves 740 perform circular motion, causing several first connecting rods 750 to slide along the arc of the first arc-shaped grooves 740 to the middle of the arc, which in turn causes several grippers 720 to move radially towards the midpoint of the slide block 710. This allows the grippers 720 to hold the steel column 100. This holding process continues until the moving frame 230 slides to its leftmost position, at which point the grippers 720 finally contact the steel column 100.

[0082] When the first motor 241 drives the moving frame 230 to slide to the right, since the pawl 7664 moves in the same direction as the teeth of the ratchet 7663, the pawl 7664 will continuously bounce back under the action of the spring plate 7665, and will not drive the ratchet 7663 to rotate. As a result, the rotary seat 730 will not rotate during this process, and the several grippers 720 will not release their grip on the steel column 100.

[0083] When the first motor 241 drives the moving frame 230 to slide to the left to the middle side, the rotary seat 730 continues to make circular motion. At this time, several first connecting rods 750 slide to the tail end of several first arc grooves 740, causing several grippers 720 to move radially in the opposite direction to release the steel column 100.

[0084] It should be further explained that the positions of the several grippers 720 can avoid the recesses of the tooth grooves 120 cut by the tooth cutter 530, so as not to affect the tooth cutting. When the tooth cutter 530 changes position and passes through several grippers 720, it can be matched with the reciprocating retraction process of the tooth cutter 530. Alternatively, by adding several tooth cutters 530, the tooth cutter 530 can be rotated only a fraction of a turn.

[0085] Example 3

[0086] When the steel column 100 is fed and the gripper 720 has not yet finished clamping, in order to support the steel column 100 and prevent it from falling, and at the same time when the steel column 100 is being processed on the left and right sides, the support component 780 does not affect the processing of the milling mechanism 400, the gear-cutting mechanism 500 and the drilling mechanism 600, embodiment 3 is proposed.

[0087] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figures 3-10 The clamping mechanism 700 also includes a guide assembly 770 and several support assemblies 780;

[0088] Several support components 780 are used to support the steel column 100 when it is fed into the movable frame 230, and guide components 770 are used to remove the support of several support components 780 on the steel column 100 after the steel column 100 is clamped by several grippers 720.

[0089] The guide assembly 770 includes two guide rods 771 symmetrically arranged on the slide block 710, and two second arc-shaped grooves 772 symmetrically opened on the housing 210. The radius of the second arc-shaped grooves 772 gradually increases from the middle to both sides, and the two guide rods 771 are slidably arranged in the two second arc-shaped grooves 772 respectively.

[0090] The support assembly 780 includes a support block 781 that is slidably disposed within the movable frame 230. The support block 781 is elastically connected to the inner wall of the movable frame 230 via a spring 782. A second connecting rod 783 is provided on the slide block 710, and a groove 784 is provided on the second connecting rod 783.

[0091] The support assembly 780 also includes a third connecting rod 785, one end of which is hinged to the support block 781, and the other end of which is slidably connected to the slide groove 784.

[0092] In this embodiment: when the steel column 100 moves upward, it first contacts the inclined surfaces of several support blocks 781, pushing the support blocks 781 outward to move radially, and then returns to its original position under the action of several springs 782, supporting the steel column 100. During this process, one end of several third connecting rods 785 slides upward along several sliding grooves 784 without driving the second connecting rods 783.

[0093] During the sliding process to the left and right sides, the slide block 710 moves upward as a whole due to the guidance of the second arc groove 772. The steel column 100 moves away from several support blocks 781. At the same time, under the drive of several second connecting rods 783, several support blocks 781 are retracted into the moving frame 230, so as not to affect the processing.

[0095] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
