Description

Technical Field

[0001] The present invention belongs to the field of gear shaping machining, and more particularly to an annular raw material preparation device for gear machining. Background Art

[0002] Gear shaping machining is a cutting machining method for manufacturing gears, mainly used for machining various types of gears, especially those that are difficult to machine by other methods. Gear shaping machining utilizes a shaping cutter to perform a high-speed reciprocating linear motion along the axis direction of the workpiece on a gear shaper, while engaging with the workpiece without clearance. During the machining process, the tooth profile of the shaping cutter matches the tooth groove shape of the gear, and the tooth profile is formed through multiple cuts. Gear shaping machining can achieve high machining accuracy and a small tooth surface roughness value, and is suitable for machining high-precision gears.

[0003] A patent document with the publication number CN212144814U discloses a gear shaping device for gear machining, including a base plate, a rotating mechanism, a shaping mechanism, a vertical plate, a control panel, a top plate, a clamping mechanism, a rotating mechanism, and a shaping mechanism. One end of the top of the base plate away from the shaping mechanism is fixedly connected with a vertical plate, and a control panel is fixedly installed on the outer side of the vertical plate.

[0004] In the traditional gear shaping machining technical solution, the gear to be machined is usually sleeved outside a threaded cylinder. To ensure machining accuracy, a nut is tightened above the threaded cylinder and a gasket is used to axially fix the gear. After fixation, the gear is located on the side of the shaping cutter. During the machining process, the shaping cutter performs multiple linear lifting motions to machine the tooth profile of the gear. However, in this process, although the upper and lower parts of the gear are fixed by the nut and gasket, due to machining accuracy differences, the relative position of most gears with respect to the threaded cylinder is not precise during fixation. In addition, the entire machining process requires multiple steps to be completed sequentially, the operation process is relatively cumbersome, and the efficiency is low.

[0005] Therefore, the present invention provides an annular raw material preparation device for gear machining. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: An annular raw material preparation device for gear processing described in the present invention includes gear processing equipment. On one side of the upper end of the gear processing equipment, a gear shaping component is installed. Above the gear processing equipment, a rotating base is movably installed. Above the rotating base, a gear workpiece is placed. Above the rotating base, a columnar member is installed. The columnar member includes a fixed cylinder fixedly installed above the rotating base. Above the fixed cylinder, a threaded column is fixedly installed. Outside the fixed cylinder, a plurality of movable pressing members are movably installed; A screwing component is movably installed outside the threaded column. A gasket is sleeved outside the threaded column. The interior of the columnar member is hollow. An inner column is movably installed in the hollow interior of the columnar member. Above the inner column, a connecting member is movably installed. The inner column is connected to the screwing component through the connecting member. An inner ring groove is penetrated and opened inside the gear workpiece.

[0008] Preferably, the movable pressing member is an L-shaped special-shaped block. The plurality of movable pressing members are evenly distributed outside the fixed cylinder, and the heights of the plurality of movable pressing members are different. A plurality of downward pressing and rotating members are movably installed inside the fixed cylinder. The plurality of downward pressing and rotating members are connected to the corresponding movable pressing members.

[0009] Preferably, a component groove is penetrated and opened inside the fixed cylinder. The component groove is communicated with the hollow interior of the columnar member. One end of the movable pressing member connected to the downward pressing and rotating member is located inside the component groove. A plurality of circular ring grooves are opened at the lower end position of the inner column. The component groove is communicated with the circular ring grooves.

[0010] Preferably, the downward pressing and rotating member includes a circular ring body rotatably and vertically installed inside the component groove. At the axial center position of the circular ring body, a component column is installed. The bottom of the component column is fixedly connected to the inner wall of the component groove. On one side of the component column, a sliding column is fixedly installed. A path groove is opened on the inner wall of the circular ring body.

[0011] Preferably, one end of the sliding column is smoothly arranged and slidably installed inside the path groove. The path groove is arranged in a spiral upward path. A compression spring is fixedly installed below the circular ring body. The lower end of the compression spring is fixedly connected to the inner wall of the component groove.

[0012] Preferably, the contact surface between the upper part of the circular ring body and the inner wall of the circular ring groove is smoothly arranged. The circular ring body rotates inside the component groove with the component column as the center of the circle.

[0013] Preferably, a hydraulic lifting column is movably installed inside the gear shaping component. A gear shaping cutter is fixedly installed below the hydraulic lifting column. A universal infusion pipe is fixedly installed on the side of the gear shaping component. A liquid cooling nozzle is fixedly installed at the lower end of the universal infusion pipe.

[0014] Preferably, the screwing assembly includes a nut threadedly connected to the outside of the threaded column and a multi-sided ring body sleeved on the outside of the nut, and the space between the nut and the multi-sided ring body is rough.

[0015] Preferably, a through ring groove is formed through the inside of the gasket, the diameter of the through ring groove is larger than the maximum diameter of the nut, and the diameter of the through ring groove is smaller than the maximum diameter of the multi-sided ring body.

[0016] Preferably, the connecting member includes a rotating block rotatably installed at the upper end of the inner column and a plurality of L-shaped rods fixedly installed on the outside of the rotating block. A sliding bar is slidably installed inside the lower ends of the plurality of L-shaped rods. The lower end of the sliding bar is fixedly connected above the nut. A screw rod is threadedly installed on the outside of the lower end of the L-shaped rod, and one end of the screw rod faces the upper end of the sliding bar.

[0017] The beneficial effects of the present invention are as follows: 1. For the annular raw material preparation device for gear processing of the present invention, through the screwing of the screwing assembly, the outside of the plurality of movable pressing members abuts against the inner wall of the gear workpiece, ensuring that the axis of the gear workpiece and the axis of the fixed cylinder are on the same vertical line. When the screwing assembly descends and rotates, it will press down the gasket to make it closely adhere to the upper part of the gear workpiece. At this time, through the screwing work of the screwing assembly and the cooperation of the pressing of the gasket, the up and down positions of the gear workpiece are fixed, and at this time, the axis position of the gear workpiece is also determined. Subsequently, the gear workpiece is cut by the gear shaping component installed on one side of the gear workpiece. At this time, the tooth shape of the gear shaping component matches the shape of the tooth groove required by the gear workpiece, and the tooth shape is formed through multiple cuttings.

[0018] 2. For the annular raw material preparation device for gear processing of the present invention, compared with the traditional gear structure, the cooperation between the downward rotating member and the movable pressing member in this device will reduce the stress generated when the movable pressing member presses. When the gear meshing structure realizes the pressing effect, the hard extrusion between teeth will shorten the service life of this device. When the inner column rises and the movable pressing member rotates and no longer abuts against the inner wall of the inner ring groove, the restoring force of the compression spring will make the sliding column slide from the top position of the path groove to the bottom position of the path groove. The rebounding structure set in this device facilitates labor-saving during work.

[0019] 3. In the annular raw material preparation device for gear processing according to the present invention, when the screwing component descends, the L-shaped rod and the sliding bar with a fixed length cause the rotating block to rotate and descend, that is, drive the inner column to descend vertically. When the inner column descends vertically and cooperates with the downward pressing and rotating component, a plurality of corresponding movable pressing parts will rotate and press against the inner wall of the inner ring groove to fix the gear workpiece, which simplifies and accurately positions the processing of the gear workpiece. When dealing with gear workpieces with different diameters of inner ring grooves, by loosening the screw rod, the sliding bar slides inside the L-shaped rod, thereby adjusting the height of the L-shaped rod and the sliding bar, so that the descending distance of the inner column and the descending distance required by the screwing component can both be adjusted, and thus it is applicable to more types of gear workpieces.

Specific implementation mode

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0024] Example 1: As Figure 1-7 shown, a ring-shaped raw material preparation device for gear processing according to an embodiment of the present invention includes gear processing equipment 1. A gear shaper component 3 is installed on one side of the upper end of the gear processing equipment 1. A rotating base 11 is movably installed above the gear processing equipment 1. A gear workpiece 2 is placed above the rotating base 11. A cylindrical component 4 is installed above the rotating base 11. The cylindrical component 4 includes a fixed cylinder 42 fixedly installed above the rotating base 11. A threaded column 41 is fixedly installed above the fixed cylinder 42. A plurality of movable pressing members 43 are movably installed on the outer side of the fixed cylinder 42; A screwing component 6 is movably installed on the outer side of the threaded column 41. A gasket 5 is sleeved on the outer side of the threaded column 41. The inside of the cylindrical component 4 is hollow. An inner column 45 is movably installed in the hollow inside of the cylindrical component 4. A connecting component 7 is movably installed above the inner column 45. The inner column 45 is connected to the screwing component 6 through the connecting component 7. An inner ring groove 21 is penetrated and opened inside the gear workpiece 2.

[0025] Specifically, when the annular blank needs to be processed into a gear, first, the unshaped gear workpiece 2 is sleeved outside the cylindrical member 4. At this time, the bottom of the gear workpiece 2 contacts the upper part of the rotating base 11. At this time, the gasket 5 is above the gear workpiece 2, and the screwing assembly 6 is above the gasket 5. When the gear workpiece 2 needs to be fixed, the screwing assembly 6 is rotated to rotate and descend outside the threaded column 41. At this time, the screwing assembly 6 is connected to the connecting member 7. Under the action of the connecting member 7, the screwing assembly 6 rotates and descends while the inner column 45 inside the cylindrical member 4 descends vertically. The descent of the inner column 45 inside the fixed cylinder 42 cooperates with the structure that makes the movable pressing member 43 rotate, which will cause multiple movable pressing members 43 arranged outside the fixed cylinder 42 to rotate simultaneously, so that the movable pressing members 43 change from the state of originally clinging to the outside of the fixed cylinder 42 to the state of pressing against the inner wall of the gear workpiece 2. As the screwing assembly 6 continues to be screwed, the outer sides of multiple movable pressing members 43 press against the inner wall of the gear workpiece 2, ensuring that the axis of the gear workpiece 2 and the axis of the fixed cylinder 42 are on the same vertical line. Even if the machining accuracies of the same type of gear workpieces 2 are different, the rotation and pressing of multiple movable pressing members 43 will accurately position the machining position of the gear workpiece 2. When the screwing assembly 6 descends and rotates, it presses down the gasket 5 to make it cling to the upper part of the gear workpiece 2. At this time, under the screwing operation of the screwing assembly 6 and the cooperation of the pressing of the gasket 5, the up and down positions of the gear workpiece 2 are fixed, and the axis position of the gear workpiece 2 is also determined at this time. Therefore, the machining position of the gear workpiece 2 is further confirmed. Subsequently, the gear workpiece 2 is cut by the gear shaping assembly 3 installed on one side of the gear workpiece 2. At this time, the tooth profile of the gear shaping assembly 3 matches the shape of the tooth groove required by the gear workpiece 2, and the tooth profile is formed through multiple cuttings. The gear shaping machining in this device can achieve a high machining accuracy. Because the positioning method of the gear workpiece 2 is simplified, the efficiency of the gear shaping machining is significantly enhanced. In this device, the relative positions of the gear workpiece 2 and the cylindrical member 4 always remain the same, and the machining position of the gear shaping assembly 3 does not need to be frequently changed, thereby enhancing the machining efficiency.

[0026] As Figure 6-9 shown, the movable pressing member 43 is an L-shaped special-shaped block. Multiple movable pressing members 43 are evenly distributed outside the fixed cylinder 42, and the heights of multiple movable pressing members 43 are different. A plurality of downward pressing and rotating members 44 are movably installed inside the fixed cylinder 42, and the plurality of downward pressing and rotating members 44 are connected to the corresponding movable pressing members 43.

[0027] A member groove 421 is penetrated and opened inside the fixed cylinder 42. The member groove 421 is communicated with the hollow inside of the cylindrical member 4. One end of the movable pressing member 43 connected to the downward pressing and rotating member 44 is inside the member groove 421. A plurality of circular ring grooves 451 are opened at the lower end position of the inner column 45. The member groove 421 is communicated with the circular ring grooves 451.

[0028] The downward pressing and rotating member 44 includes a toroidal body 441 rotatably and liftably installed inside the member groove 421. A member column 442 is installed at the axial center position of the toroidal body 441. The bottom of the member column 442 is fixedly connected to the inner wall of the member groove 421. A sliding column 443 is fixedly installed on one side of the member column 442. A path groove 4411 is formed in the inner wall of the toroidal body 441.

[0029] One end of the sliding column 443 is smoothly arranged and slidably installed inside the path groove 4411. The path groove 4411 is arranged in a spiral upward path. A compression spring 444 is fixedly installed below the toroidal body 441. The lower end of the compression spring 444 is fixedly connected to the inner wall of the member groove 421.

[0030] The contact surface between the upper part of the toroidal body 441 and the inner wall of the toroidal groove 451 is smoothly arranged. The toroidal body 441 rotates inside the member groove 421 with the member column 442 as the center of the circle.

[0031] Specifically, when the rotating and descending of the screwing assembly 6 presses down the gasket 5 and drives the inner column 45 to descend, at this time, the upper inner wall above the circular ring groove 451 opened at the lower end of the inner column 45 contacts the upper part of the corresponding circular ring body 441, and the sliding column 443 is at the bottommost position of the path groove 4411. When the inner column 45 descends, it will press down the circular ring body 441. At this time, the sliding column 443 will slide and rise in the path of the path groove 4411, that is, the circular ring body 441 descends and rotates. At this time, the compression spring 444 is compressed. The descending rotation of the circular ring body 441 will drive the movable pressing member 43 installed on the outer side of the circular ring body 441 to descend and rotate. One side of the rotating movable pressing member 43 will gradually press against the inner wall of the inner ring groove 21 and squeeze it. Multiple movable pressing members 43 are evenly distributed on the outer side of the fixed cylinder 42. Through the same setting, the outer sides of multiple movable pressing members 43 will simultaneously press against the inner wall of the inner ring groove 21, thereby confirming the position of the gear workpiece 2, making the gear workpiece 2 always in a fixed position relative to the column member 4. Through the setting of this device, when the movable pressing member 43 is in its original state and closely adheres to the outer side of the fixed cylinder 42, the diameter of the fixed cylinder 42 plus the movable pressing member 43 is significantly smaller than the diameter of the inner ring groove 21, avoiding the placement of the gear workpiece 2. And when multiple movable pressing members 43 are in the pressing state after rotation, it can be applicable to gear workpieces 2 with a larger diameter. Moreover, in this device, the cooperation between the pressing and rotating member 44 and the movable pressing member 43 will reduce the stress generated when the movable pressing member 43 presses compared with the traditional gear structure. When the teeth of the gear meshing structure achieve the pressing effect, the hard extrusion between the teeth will shorten the service life of this device. When the inner column 45 rises and the movable pressing member 43 rotates and no longer presses against the inner wall of the inner ring groove 21, the restoring force of the compression spring 444 will make the sliding column 443 slide from the top position of the path groove 4411 to the bottom position of the path groove 4411. The rebound structure is set in this device to facilitate labor-saving work.

[0032] As Figure 2 shown, a hydraulic lifting column 31 is movably installed inside the gear shaping assembly 3. A gear shaping cutter 32 is fixedly installed below the hydraulic lifting column 31. A universal liquid delivery pipe 33 is fixedly installed on the side of the gear shaping assembly 3. A liquid cooling nozzle 34 is fixedly installed at the lower end of the universal liquid delivery pipe 33.

[0033] Specifically, after the position of the gear workpiece 2 is fixed, with the cooperation of the hydraulic lifting column 31, the gear shaping cutter 32 continuously rises and falls on the side of the gear workpiece 2, thereby performing the gear shaping work, making tooth grooves matching the outer tooth shape of the gear shaping cutter 32 formed on the outer side of the gear workpiece 2. When the gear shaping cutter 32 rises and falls for processing, the universal liquid delivery pipe 33 conveys the coolant inside the gear processing device 1, and the liquid cooling nozzle 34 sprays the conveyed coolant onto the processing position of the gear shaping cutter 32.

[0034] As Figure 4And Figure 10 As shown in Figure 10 , the screwing assembly 6 includes a nut 61 threadedly connected to the outside of the threaded post 41 and a multi-sided ring body 62 sleeved on the outside of the nut 61. The nut 61 and the multi-sided ring body 62 are roughened between them.

[0035] The inside of the gasket 5 is provided with a through ring groove 51. The diameter of the through ring groove 51 is larger than the maximum diameter of the nut 61 and smaller than the maximum diameter of the multi-sided ring body 62.

[0036] Specifically, when the gasket 5 is to be sleeved above the gear workpiece 2, at this time the nut 61 and the multi-sided ring body 62 are separated. Take the gasket 5. Since the diameter of the through ring groove 51 is larger than the diameter of the nut 61, the gasket 5 can be sleeved on the outside of the threaded post 41 and placed above the gear workpiece 2. Then take the multi-sided ring body 62 and sleeve it on the outside of the nut 61. The two form an integral body. Rotate the multi-sided ring body 62 and the nut 61 to make the screwing assembly 6 rotate and descend to press down the gasket 5, and it will drive the inner column 45 inside the column member 4 to descend.

[0037] Embodiment 2: As Figure 10 shown in Figure 10 , compared with Embodiment 1, another implementation manner of the present invention is: The connecting member 7 includes a rotating block 71 rotatably installed at the upper end of the inner column 45 and a plurality of L-shaped rods 72 fixedly installed on the outside of the rotating block 71. A sliding bar 73 is slidably installed inside the lower ends of the plurality of L-shaped rods 72. The lower end of the sliding bar 73 is fixedly connected to the upper side of the nut 61. A screw rod 74 is threadedly installed on the outside of the lower end of the L-shaped rod 72. One end of the screw rod 74 faces the upper end of the sliding bar 73.

[0038] Specifically, in the initial state of the screw rod 74, one end of the screw rod 74 will be screwed tightly against the side of the upper end of the sliding bar 73. That is, at this time, the heights of the L-shaped rod 72 and the sliding bar 73 are fixed. When the screwing assembly 6 descends, through the fixed-length L-shaped rod 72 and the sliding bar 73, the rotating block 71 is rotated and descended, that is, the inner column 45 is driven to descend vertically. The vertical descent of the inner column 45, through the cooperation with the downward pressing and rotating member 44, will cause a plurality of corresponding movable pressing members 43 to rotate and press against the inner wall of the inner ring groove 21 to fix the gear workpiece 2, which is simple and accurate for the machining positioning of the gear workpiece 2. When it comes to gear workpieces 2 with inner ring grooves 21 of different diameters, by loosening the screw rod 74, the sliding bar 73 slides inside the L-shaped rod 72, thereby adjusting the heights of the L-shaped rod 72 and the sliding bar 73, so that the descending distance of the inner column 45 and the descending distance required by the screwing assembly 6 can both be adjusted, and thus it is applicable to more types of gear workpieces 2.

[0039] Working principle: When the annular blank needs to be processed into a gear, first sleeve the gear workpiece 2 that has not been gear hobbing on the outside of the cylindrical member 4. At this time, the bottom of the gear workpiece 2 contacts the upper part of the rotating base 11. At this time, the gasket 5 is above the gear workpiece 2, and the screwing component 6 is above the gasket 5. When the gear workpiece 2 needs to be fixed, rotate the screwing component 6 to make it rotate and descend outside the threaded column 41. At this time, the screwing component 6 is connected to the connecting member 7. Under the action of the connecting member 7, while the screwing component 6 rotates and descends, the inner column 45 inside the cylindrical member 4 descends vertically. The descent of the inner column 45 inside the fixed cylinder 42 cooperates with the structure that makes the movable pressing member 43 rotate, which will cause multiple movable pressing members 43 arranged outside the fixed cylinder 42 to rotate simultaneously, so that the movable pressing members 43 change from the state of originally clinging to the outside of the fixed cylinder 42 to the state of pressing against the inner wall of the gear workpiece 2. As the screwing component 6 continues to be screwed, the outside of multiple movable pressing members 43 presses against the inner wall of the gear workpiece 2, ensuring that the axis of the gear workpiece 2 and the axis of the fixed cylinder 42 are on the same vertical line. Even if the machining accuracy of the same type of gear workpiece 2 is different, the rotation and pressing of multiple movable pressing members 43 will accurately position the machining position of the gear workpiece 2. When the screwing component 6 descends and rotates, it will press down the gasket 5 to make it cling to the upper part of the gear workpiece 2. At this time, through the screwing operation of the screwing component 6 and the cooperation of pressing down by the gasket 5, the up and down position of the gear workpiece 2 is fixed. At this time, the axis position of the gear workpiece 2 is also determined. Therefore, the machining position of the gear workpiece 2 is further confirmed. Subsequently, the gear hobbing component 3 installed on one side of the gear workpiece 2 performs gear hobbing on it. At this time, the tooth profile of the gear hobbing component 3 matches the tooth groove shape required by the gear workpiece 2, and the tooth profile is formed through multiple cuttings. In this device, the gear hobbing processing can achieve a relatively high machining accuracy. Because the positioning method of the gear workpiece 2 is simplified, the efficiency of gear hobbing processing is significantly enhanced. In this device, the relative position between the gear workpiece 2 and the cylindrical member 4 always remains the same, without frequently changing the machining position of the gear hobbing component 3, thereby enhancing the processing efficiency. In the initial state of the screw rod 74, one end of the screw rod 74 will be screwed tightly against the side of the upper end of the sliding strip 73, that is, at this time, the heights of the L-shaped rod 72 and the sliding strip 73 are fixed. When the screwing component 6 descends, through the fixed-length L-shaped rod 72 and sliding strip 73, the rotating block 71 rotates and descends, that is, drives the inner column 45 to descend vertically. The vertical descent of the inner column 45, through cooperation with the downward pressing and rotating member 44, will cause multiple corresponding movable pressing members 43 to rotate and press against the inner wall of the inner ring groove 21 to fix the gear workpiece 2, simplifying and accurately positioning the machining of the gear workpiece 2. When dealing with gear workpieces 2 with different diameters of the inner ring groove 21, loosen the screw rod 74 to make the sliding strip 73 slide inside the L-shaped rod 72, thereby adjusting the heights of the L-shaped rod 72 and the sliding strip 73.The distance by which the inner column 45 descends and the distance by which the screwing assembly 6 needs to descend can both be adjusted, thereby being applicable to more types of gear workpieces 2.
