Description

Technical Field

[0001] The invention belongs to the field of gear slotting processing, in particular to a ring-shaped raw material preparation device for gear processing. Background Art

[0002] Gear shaping is a cutting method used to manufacture gears. It is mainly used to process various types of gears, especially those that are difficult to process using other methods. Gear shaping is a process in which a gear shaping cutter is moved back and forth at high speed along the axis of the workpiece on a gear shaping machine while simultaneously meshing with the workpiece without any gaps. During the machining process, the tooth profile of the gear shaping cutter matches the tooth groove shape of the gear. The tooth profile is formed through multiple cuts. Gear shaping can achieve high machining accuracy with low tooth surface roughness, making it suitable for machining high-precision gears.

[0004] In traditional gear shaping processing technology, the gear to be processed is usually sleeved on the outside of the threaded cylinder. To ensure processing accuracy, the nut is tightened on the threaded cylinder and the gear is axially fixed with a gasket. The fixed gear is located on the side of the gear shaping cutter. During the processing, the gear shaping cutter performs multiple linear lifting and lowering movements to cut the gear tooth profile. However, in this process, although the upper and lower parts of the gear are fixed by nuts and gaskets, the relative position of most gears to the threaded cylinder is not accurate when fixed due to differences in processing accuracy. In addition, the entire processing process requires multiple steps to be completed in sequence, and the operation process is relatively cumbersome and inefficient.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention relates to a ring-shaped raw material preparation device for gear processing. By screwing the screwing assembly, the outer sides of multiple movable pressing parts are pressed against the inner wall of the gear workpiece to ensure that the axis of the gear workpiece and the axis of the fixed cylinder are in the same vertical line. When the screwing assembly descends and rotates, the gasket is pressed down to make it close to the top of the gear workpiece.

At this time, the tooth shape of the gear shaping assembly matches the tooth groove shape required by the gear workpiece, and the tooth shape is formed through multiple cutting.

[0020] 2. The present invention describes a ring-shaped raw material preparation device for gear processing. Compared with the traditional gear structure, the coordination of the downward-pressing rotating component and the movable pressure member in the device can reduce the stress generated by the movable pressure member during pressure. When the gear meshing structure realizes the pressure effect, the hard squeezing between the teeth will shorten the service life of the device. When the inner column rises, the movable pressure member rotates and no longer presses against the inner wall of the inner ring groove, the restoring force of the compression spring will cause the sliding column to slide from the top position of the path groove to the bottom position of the path groove. A rebound structure is provided in the device to facilitate work and save effort.

[0021] 3. The annular raw material preparation device for gear processing described in the present invention, when the screw assembly descends, the L-shaped rod and the sliding bar with fixed length cause the rotating block to rotate and descend, that is, drive the inner column to descend vertically. The vertical descent of the inner column, in cooperation with the downward pressing rotating component, will cause multiple corresponding movable pressing parts to rotate and press against the inner wall of the inner ring groove to fix the gear workpiece, which is simple and accurate for the processing positioning of the gear workpiece. When targeting gear workpieces with inner ring grooves of different diameters, the sliding bar is allowed to slide inside the L-shaped rod by loosening the screw rod, and then the height of the L-shaped rod and the sliding bar is adjusted, so that the distance the inner column descends and the distance the screw assembly needs to descend can be adjusted, thereby being suitable for more types of gear workpieces.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1: Figure 1-7 As shown, an annular raw material preparation device for gear processing according to an embodiment of the present invention includes a gear processing device 1, a gear shaping assembly 3 is installed on one side of the upper end of the gear processing device 1, a rotating base 11 is movably installed above the gear processing device 1, a gear workpiece 2 is placed above the rotating base 11, a column member 4 is installed above the rotating base 11, and the column member 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, and a plurality of movable pressure members 43 are movably installed on the outer side of the fixed cylinder 42;

[0036] A screwing assembly 6 is movably installed on the outer side of the threaded column 41, and a gasket 5 is sleeved on the outer side of the threaded column 41. The interior of the column member 4 is hollow, and an inner column 45 is movably installed in the hollow interior of the column member 4. A connecting member 7 is movably installed above the inner column 45. The inner column 45 is connected to the screwing assembly 6 through the connecting member 7, and an inner ring groove 21 is opened through the interior of the gear workpiece 2.

[0037] Specifically, when the annular blank needs to be processed to make it into a gear, the gear workpiece 2 that has not been processed by gear shaping is first sleeved on the outside of the column member 4. At this time, the bottom of the gear workpiece 2 is in contact with the top of the rotating base 11. At this time, the gasket 5 is above the gear workpiece 2, and the screw assembly 6 is above the gasket 5. When the gear workpiece 2 needs to be fixed, the screw assembly 6 is rotated and lowered on the outside of the threaded column 41. At this time, the screw assembly 6 and the connecting member 7 are connected. Under the action of the connecting member 7, the screw assembly 6 makes the inner column 45 inside the column member 4 descend vertically while rotating and descending. 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 makes the multiple movable pressing members 43 arranged on the outside of the fixed cylinder 42 rotate at the same time, so that the movable pressing members 43 rotate from the state originally close 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 screw, the outer sides of the multiple movable pressing members 43 press against the inner wall of the gear workpiece 2, ensuring that the gear workpiece The axis of 2 is on the same vertical line as the axis of the fixed cylinder 42. Even if the processing accuracy of similar gear workpieces 2 is different, the rotation and pressure of multiple movable pressing members 43 can accurately determine the processing position of the gear workpiece 2. When the screwing assembly 6 descends and rotates, it presses the gasket 5 down to make it close to the top of the gear workpiece 2. At this time, under the tightening work of the screwing assembly 6, the upper and lower positions of the gear workpiece 2 are fixed by the downward pressure of the gasket 5. At this time, the axis position of the gear workpiece 2 is also determined. Therefore, the processing position of the gear workpiece 2 is further confirmed. Subsequently, the gear shaping assembly 3 installed on one side of the gear workpiece 2 is used for shaping. At this time, the tooth shape of the gear shaping assembly 3 is matched with the tooth groove shape required by the gear workpiece 2. The tooth shape is formed by multiple cutting. The gear shaping process in this device can achieve higher processing accuracy. Because the positioning means of the gear workpiece 2 is simplified, the efficiency of the gear shaping process is significantly enhanced. In this device, the relative position of the gear workpiece 2 and the column member 4 is always consistent, and there is no need to frequently change the processing position of the gear shaping assembly 3, thereby enhancing the processing efficiency.

[0038] like Figure 6-9 As shown, the movable pressure piece 43 is an L-shaped special-shaped block, and multiple movable pressure pieces 43 are evenly distributed on the outside of the fixed cylinder 42, and the multiple movable pressure pieces 43 have different heights. Multiple downward-pressing rotating components 44 are movably installed inside the fixed cylinder 42, and the multiple downward-pressing rotating components 44 are connected to the corresponding movable pressure pieces 43.

[0039] A component groove 421 is provided inside the fixed cylinder 42, and the component groove 421 is connected to the hollow interior of the column component 4. The end of the movable pressure piece 43 connected to the downward pressing rotating component 44 is located inside the component groove 421. A plurality of annular grooves 451 are provided at the lower end of the inner column 45, and the component groove 421 is connected to the annular groove 451.

[0040] The downward-pressing rotating component 44 includes a circular body 441 that is rotatably and liftably installed inside the component groove 421. A component column 442 is installed at the axial position of the circular body 441. The bottom of the component column 442 is fixedly connected to the inner wall of the component groove 421. A sliding column 443 is fixedly installed on one side of the component column 442. A path groove 4411 is opened on the inner wall of the circular body 441.

[0041] One end of the sliding column 443 is smoothly set and slidably installed inside the path groove 4411. The path groove 4411 is a spiral upward path setting. A compression spring 444 is fixedly installed below the annular body 441. The lower end of the compression spring 444 is fixedly connected to the inner wall of the component groove 421.

[0042] The upper portion of the annular body 441 and the inner wall contact surface of the annular groove 451 are smoothly arranged, and the annular body 441 rotates inside the component groove 421 with the component column 442 as the center.

[0043] When the inner column 45 is lowered, the ring body 441 is pressed downwards. At this time, the sliding post 443 slides and rises in the path of the path groove 4411, that is, the ring body 441 descends and rotates. At this time, the compression spring 444 is compressed, and the downward rotation of the ring body 441 drives the movable pressing piece 43 installed on the outer side of the ring body 441 to rotate downwards. One side of the rotating movable pressing piece 43 gradually contacts the inner wall of the inner ring groove 21 and squeezes it. Multiple movable pressing pieces 43 are evenly distributed on the outside of the fixed cylinder 42. Through the same arrangement, the outer sides of multiple movable pressing pieces 43 are squeezed on the inner wall of the inner ring groove 21 at the same time, thereby confirming the position of the gear workpiece 2, so that the gear workpiece 2 is relative to the column. The body component 4 is always in a fixed position. Through the setting of this device, when the movable pressure piece 43 is in its original state and is tightly attached to the outside of the fixed cylinder 42, the diameter of the fixed cylinder 42 plus the movable pressure piece 43 will be significantly smaller than the diameter of the inner ring groove 21, avoiding the placement of the gear workpiece 2. When multiple movable pressure pieces 43 are in a pressing state after rotation, they can be suitable for gear workpieces 2 with larger diameters. In addition, the cooperation between the downward pressing rotating component 44 and the movable pressure piece 43 in this device will reduce the stress generated by the movable pressure piece 43 when pressing compared to the traditional gear structure. When the gear meshing structure achieves the pressing effect, the hard squeezing between the teeth will shorten the service life of this device. When the inner column 45 rises, so that the movable pressure piece 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 cause the sliding column 443 to slide from the top position of the path groove 4411 to the bottom position of the path groove 4411. A rebound structure is provided in this device to facilitate work and save effort.

[0044] like Figure 2 As 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 infusion tube 33 is fixedly installed on the side of the gear shaping assembly 3, and a liquid cooling nozzle 34 is fixedly installed at the lower end of the universal infusion tube 33.

[0045] Specifically, after the position of the gear workpiece 2 is fixed, the gear shaping cutter 32 is continuously raised and lowered on the side of the gear workpiece 2 with the cooperation of the hydraulic lifting column 31, and then the gear shaping work is performed, so that the outer side of the gear workpiece 2 forms a tooth groove that matches the outer tooth shape of the gear shaping cutter 32. When the gear shaping cutter 32 is raised and lowered for processing, the universal infusion pipe 33 transports the coolant inside the gear processing equipment 1, and the liquid cooling nozzle 34 sprays the transported coolant onto the processing position of the gear shaping cutter 32.

[0046] like Figure 4and Figure 10 As shown, the screwing assembly 6 includes a nut 61 threadedly connected to the outside of the threaded column 41 and a polygonal ring body 62 sleeved on the outside of the nut 61, and a rough surface is provided between the nut 61 and the polygonal ring body 62.

[0047] A through-groove 51 is formed inside the gasket 5 . The diameter of the through-groove 51 is larger than the maximum diameter of the nut 61 , and smaller than the maximum diameter of the polygonal ring 62 .

[0048] Specifically, when the gasket 5 is to be sleeved on the top of the gear workpiece 2, the nut 61 and the polygonal ring body 62 are separated, and the gasket 5 is taken. Since the diameter of the ring groove 51 is larger than the diameter of the nut 61, the gasket 5 can be sleeved on the outside of the threaded column 41 and placed on the gear workpiece 2. Then the polygonal ring body 62 is taken and sleeved on the outside of the nut 61. The two are formed into one. The polygonal ring body 62 and the nut 61 are rotated to rotate and descend to press down the gasket 5, and the inner column 45 inside the columnar component 4 will be driven to descend.

[0049] Example 2: Figure 10 As shown, comparative example 1, another embodiment of the present invention is: the connecting member 7 includes a rotating block 71 rotatably mounted on the upper end of the inner column 45 and a plurality of L-shaped rods 72 fixedly mounted on the outside of the rotating block 71, a sliding bar 73 is slidably mounted 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 part of the nut 61, a screw rod 74 is threadedly mounted on the outer side of the lower end of the L-shaped rod 72, and one end of the screw rod 74 is arranged toward the upper end of the sliding bar 73.

[0050] When the cam 72 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the cam 72 is unlocked and the locking cam 73 is unlocked.

[0051] Working principle: when the annular blank needs to be processed to make it into a gear, the gear workpiece 2 that has not been processed by gear shaping is first sleeved on the outside of the column member 4. At this time, the bottom of the gear workpiece 2 is in contact with the top 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 and descended on the outside of the threaded column 41. At this time, the screwing assembly 6 and the connecting member 7 are connected. Under the action of the connecting member 7, the screwing assembly 6 rotates and descends while the inner column 45 inside the column member 4 descends vertically. The descent of the inner column 45 inside the fixed cylinder 42 cooperates with the structure that causes the movable pressing member 43 to rotate, which will make the fixed The plurality of movable pressing members 43 provided on the outside of the fixed cylinder 42 rotate simultaneously, so that the movable pressing member 43 rotates from the state originally tightly attached to the outside of the fixed cylinder 42 to the state of abutting against the inner wall of the gear workpiece 2. As the screwing assembly 6 continues to be screwed, the outer sides of the plurality of movable pressing members 43 abut 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 in the same vertical line. Even if the machining accuracy of similar gear workpieces 2 is different, the rotation and pressure of the plurality of movable pressing members 43 can accurately determine 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 tightly attached to the top of the gear workpiece 2. At this time, under the tightening work of the screwing assembly 6, the gear workpiece 2 is tightened by the downward pressure of the gasket 5. The upper and lower positions of the gear workpiece 2 are fixed, and the axial position of the gear workpiece 2 is also determined at this time. Therefore, the processing position of the gear workpiece 2 is further confirmed, and then the gear shaping component 3 installed on one side of the gear workpiece 2 is used for shaping. At this time, the tooth shape of the gear shaping component 3 matches the tooth groove shape required by the gear workpiece 2. The tooth shape is formed by multiple cuttings. The gear shaping process in this device can achieve higher processing accuracy. Due to the simplified positioning means of the gear workpiece 2, the efficiency of the gear shaping process is significantly enhanced. In this device, the relative position of the gear workpiece 2 and the column member 4 is always consistent, and there is no need to frequently change the processing position of the gear shaping 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 When the cam 72 is in the closed position, the cam 73 is in the closed position, and the cam 73 is in the open position, so that the cam 73 is in the open position, and the cam 73 is in the open position, so that the cam 73 is in the open position, and the cam 73 is in the open position, so that the cam 73 is in the open position, and the cam 73 is in the open position, so that the cam 73 is in the open position, and the cam 73 is in the open position, so that the cam 73 is in the open position, and the cam 73 is in the open position.The distance that the inner column 45 descends and the distance that the screw assembly 6 needs to descend can be adjusted, thereby being applicable to more types of gear workpieces 2.
