Description

Technical Field

[0001] This utility model belongs to the technical field of worm gear processing equipment, and relates to a special cyclone milling machine for short worm gears. Background Technology

[0002] Worm gears are commonly used transmission components in the machinery industry, primarily machined using cyclone milling machines. For example, the structure of a precision cyclone milling machine and method for fully automated machining of small-module worm gears disclosed in Chinese patent application (application number: 201710476143.3) is the same, including a machine bed mechanism, a loading mechanism assembly, a digital control platform assembly, a cyclone milling head mechanism assembly, a discharge conveyor belt, a hydraulic system mechanism, a constant temperature filtration system, and an oil mist collection system. The loading mechanism lifts the rod-shaped workpiece from the bottom to the top of the loading trough, then clamps it with a mechanical gripper and transfers it to the machine spindle for fixation. The machine spindle then drives the workpiece to rotate, while the cyclone milling head mechanism simultaneously drives the workpiece to rotate at high speed and feeds it at low speed along the workpiece's axial direction, forming threads on the workpiece's outer surface.

[0003] Because the aforementioned cyclone milling machine requires the mechanical clamping arm to hold one end of the workpiece during loading, and then insert the workpiece into the machine spindle from the rear of the spindle, the end of the workpiece held by the mechanical clamping arm is always outside the machine spindle after the workpiece is fixed. This results in a shorter workpiece that can be machined, making it impossible to directly use short materials to machine shorter worm gears. Instead, a longer workpiece must be machined first and then cut, which affects processing efficiency and increases production costs. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a special cyclone milling machine for short worm gears. The technical problem to be solved by this invention is: how to improve the processing efficiency of short worm gears.

[0005] The objective of this utility model can be achieved through the following technical solution: A short-material worm gear special cyclone milling machine, comprising a bed, a loading mechanism assembly, a machine tool spindle assembly, and a cyclone milling head assembly, wherein the machine tool spindle assembly is located between the loading mechanism assembly and the cyclone milling head assembly, characterized in that the loading mechanism assembly comprises a hopper, a lifting mechanism, and a pushing mechanism, wherein the lifting mechanism is used to lift the workpiece upward from the hopper, and the pushing mechanism has a push rod arranged laterally and capable of reciprocating laterally, wherein the push rod can push the lifted workpiece into the machine tool spindle assembly;

[0006] It also includes a tailstock mechanism located on the side of the cyclone milling head assembly away from the machine tool spindle assembly, the tailstock mechanism having a center that is laterally arranged and opposite to the machine tool spindle assembly.

[0007] This invention uses a pushing mechanism to replace the mechanical clamping arm. During loading, the push rod can completely push the lifted workpiece into the machine tool spindle assembly, allowing the portion of the workpiece held by the machine tool spindle assembly to be designed to be shorter. This eliminates the need for subsequent removal of excess workpiece parts, resulting in higher processing efficiency. Moreover, compared to loading the workpiece using a robotic arm, the push rod loading process is simpler and more efficient, further improving processing efficiency. Furthermore, the tail of the workpiece is held in place by a tailstock mechanism, which works in conjunction with the machine tool spindle assembly to fix the workpiece. This ensures workpiece stability during processing even with a shorter portion held by the machine tool spindle assembly.

[0008] In the aforementioned short-material worm gear cyclone milling machine, the hopper has a storage trough, the bottom of which is provided with a discharge channel. The lifting mechanism includes a support plate and a drive component for driving the support plate to move up and down. The support plate is located outside the discharge channel, and a drop groove for receiving workpieces is opened on the support plate. When the support plate descends to a position where the drop groove is basically flush with the discharge channel, the workpiece in the storage trough can enter the drop groove along the discharge channel. Then, the support plate rises, making the workpiece in the drop groove basically flush with the rotating chuck of the machine tool spindle assembly, facilitating the push rod to directly push the workpiece into the rotating chuck for fixation.

[0009] In the aforementioned short-material worm gear cyclone milling machine, the bottom plate of the storage trough is inclined downwards, and the discharge channel is located at the lower end of the bottom plate. Several clearance holes are spaced apart on the bottom plate of the storage trough along the width of the discharge channel. A mounting plate is provided below the bottom plate of the storage trough, and the mounting plate is connected to a drive component. The mounting plate has several push rods corresponding to the clearance holes. The drive component can drive the push rods to move up and down and extend into the storage trough through the corresponding clearance holes. When the drive component drives the pallet to move up and down, it can drive the push rods to extend into the storage trough and push the accumulated workpieces upwards, causing the workpieces to vibrate and making the workpiece discharge smoother, thus preventing jamming.

[0010] In the aforementioned short-material worm gear cyclone milling machine, the machine tool spindle assembly includes a machine tool spindle, a spindle drive mechanism, and a rotary chuck. The machine tool spindle is hollow cylindrical. The spindle drive mechanism is connected to the machine tool spindle and drives the spindle to rotate. The rotary chuck is fixed to one end of the machine tool spindle near the cyclone milling head assembly and is coaxial with the machine tool spindle. A hollow guide cylinder is coaxially fixed inside the shaft hole of the rotary spindle. One end of the guide cylinder is adjacent to the support plate, and the other end extends into the rotary chuck. By providing the guide cylinder, the workpiece lifted by the lifting mechanism can directly enter the rotary chuck along the guide cylinder, improving the fit accuracy between the workpiece and the rotary chuck.

[0011] In the aforementioned short-material worm gear cyclone milling machine, the pushing mechanism further includes a guide rail, a movable seat, and a translation drive mechanism. The guide rail is arranged horizontally, the movable seat is slidably mounted on the guide rail, and the translation drive mechanism is used to drive the movable seat to reciprocate along the guide rail. The push rod is in the shape of a long rod, and the push rod is fixed relative to the movable seat with its front end facing the rotating clamp.

[0012] In the aforementioned short-material worm gear cyclone milling machine, the cyclone milling head assembly includes a slide, a traverse drive mechanism for driving the slide to move laterally relative to the machine bed, a movable table slidably mounted on the slide, a lifting drive mechanism for driving the movable table to move up and down, and a cyclone milling head mounted on the movable table. The tailstock mechanism also includes a second drive component and a mounting base. The center is fixed to the mounting base, and the second drive component is fixed to the slide and used to drive the mounting base to move laterally and reciprocally. The tailstock mechanism is mounted on the slide to avoid interference or collision between the cyclone milling head and the tailstock mechanism during movement, and to facilitate the adjustment of the cyclone milling head's position. Moreover, when the slide drives the cyclone milling head to feed towards the machine tool spindle, the second drive component moves forward with the slide and simultaneously drives the center to retract, ensuring that the center and the tail of the workpiece always remain in contact, thus guaranteeing the stability of the workpiece during machining.

[0013] In the aforementioned short-material worm gear cyclone milling machine, the second driving component is a hydraulic cylinder, and the hydraulic cylinder's oil circuit is equipped with a pressure reducing valve and a back pressure valve. The pressure reducing valve and back pressure valve enable the second driving component to output a constant pressure. When the slide moves the cyclone milling head and the second driving component towards the machine tool spindle, the hydraulic oil in the driving component's cylinder can be depressurized through the back pressure valve, causing the piston rod to retract, thus ensuring a stable fit between the center and the workpiece.

[0014] In the aforementioned short-material worm gear milling machine, the mounting base and the moving table are connected by a cross slide mechanism. The cross slide mechanism improves the stability of the mounting base and allows it to translate relative to the moving table, preventing interference.

[0015] In the aforementioned short-material worm gear cyclone milling machine, the cross slide mechanism includes a first slide rail, a first slide block, a slide table, a second slide rail, and a second slide block. The first slide rail is vertically mounted on the moving platform. The slide table is slidably connected to the first slide rail via the first slide block. The second slide rail is horizontally mounted on the slide table. The second slide block is slidably engaged with the second slide rail and fixedly connected to the mounting base. A mounting bracket is fixedly mounted on the slide plate. One side of the mounting bracket is fixedly connected to the slide table to further improve the stability of the mounting base.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model uses a push rod to transfer the lifted workpiece into the rotating clamp for clamping and fixing, which improves the feeding efficiency. The clamping part of the workpiece can be designed to be shorter, and the workpiece can be processed to be longer. It also avoids the subsequent cutting process of the workpiece clamping part, resulting in higher overall processing efficiency.

[0018] 2. This utility model has a tailstock mechanism set on the rear side of the cyclone milling head, and the tailstock mechanism is directly set on the slide plate, which not only improves the stability of the workpiece during processing and ensures the processing accuracy, but also avoids interference or collision between the tailstock mechanism and the cyclone milling head, making it safer and more reliable.

[0019] 3. The tailstock mechanism uses a hydraulic cylinder as the driving component, and a pressure reducing valve and a back pressure valve are installed in the oil circuit. This ensures the stability of the pressure applied to the workpiece by the center, and also ensures that when the slide drives the cyclone milling head and the hydraulic cylinder to feed, the center remains stationary relative to the machine tool spindle, thus ensuring a stable fit between the center and the workpiece.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] A special cyclone milling machine for short material worm gears, such as Figure 1 and Figure 2 As shown, the machine tool includes a machine bed 1, a loading mechanism assembly 2, a machine tool spindle assembly 3, a cyclone milling head assembly 4, a tailstock mechanism 5, a hydraulic system, and an oil mist collection system. The machine bed 1 has a loading area 1a and a processing area 1b. The loading mechanism assembly 2 is located in the loading area 1a, the machine tool spindle assembly 3 is located between the loading area 1a and the processing area 1b, and the cyclone milling head assembly 4 and the tailstock mechanism 5 are located in the processing area 1b. The loading mechanism assembly 2 includes a hopper 21, a lifting mechanism, and a pushing mechanism 23. The workpieces to be processed are placed in the hopper 21, lifted one by one by the lifting mechanism, and then pushed into the rotating chuck 33 of the machine tool spindle assembly 3 by the push rod 224 of the pushing mechanism 23. The tailstock mechanism 5 provides a support for the tail of the workpiece so that the cyclone milling head 43 can process the workpiece.

[0031] Specifically, such as Figures 4-6As shown, the hopper 21 is located on one side of the machine tool spindle assembly 3. The hopper 21 has a storage trough 21a, and a discharge channel 21b is provided at the bottom of the rear side of the storage trough 21a. In this embodiment, the bottom plate of the storage trough 21a is inclined downward from the front to the rear side to facilitate the discharge of the workpiece in the storage trough 21a from the discharge channel 21b. The lifting mechanism includes a drive component 221, a mounting plate 222, and a support plate 223. The drive component 221 and the mounting plate 222 are both located below the bottom plate of the storage trough 21a. In this embodiment, the drive component 221 can be a drive component that outputs linear power, such as a cylinder or a hydraulic cylinder. The piston rod of the drive component 221 is fixedly connected to the mounting plate 222 and is used to drive the mounting plate 222 to move up and down relative to the hopper 21. The support plate 223 is fixedly connected to the mounting plate 222 and is located outside the discharge channel 21b. The top of the support plate 223 is provided with a drop groove 223a for accommodating the workpiece. When the drive unit 221 drives the pallet 223 to descend to the point where the material drop trough 223a is basically flush with or slightly lower than the material discharge channel 21b, the workpiece in the storage tank 21a can enter the material drop trough 223a through the material discharge channel 21b. Then, the drive unit 221 drives the pallet 223 and the workpiece in the material drop trough 223a to rise, so that the workpiece is directly opposite the cyclone clamp, making it easier for the push rod 233 to push the workpiece into the cyclone clamp.

[0032] Furthermore, in this embodiment, the bottom plate of the storage tank 21a is provided with a plurality of clearance holes 21c spaced apart along the width direction of the discharge channel 21b, and the mounting plate 222 is provided with a plurality of push rods 224 corresponding one-to-one with the clearance holes 21c, so that the driving component 221 can drive the mounting plate 222 and the push rods 224 to move up and down. When the support plate 223 moves up and down, the push rods 224 can extend into the storage tank 21a and push the workpiece blank upward, causing it to vibrate and preventing material jamming.

[0033] like Figure 2 , Figure 4 As shown, a horizontally arranged fixed plate 11 is provided on one side of the feeding area 1a. The pushing mechanism 23 includes a guide rail 231, a movable seat 232, a translation drive mechanism, and a push rod 233. In this embodiment, there are two guide rails 231, both of which are horizontally fixed on the fixed plate 11 and spaced vertically. The movable seat 232 is slidably connected to the two guide rails 231. The push rod 233 is a long rod shape, fixed on the movable table 42 and horizontally arranged, so that the front end of the push rod 233 faces the support plate 223 and the rotating clamp 33. The translation drive mechanism is located between the fixed plate 11 and the movable seat 232, and is used to drive the movable seat 232 and the push rod 233 to move back and forth along the guide rail 231. In this embodiment, the translation drive mechanism adopts a motor-driven screw transmission pair.

[0034] like Figure 2 , Figure 3As shown, the machine tool spindle assembly 3 is located between the loading mechanism assembly 2 and the cyclone milling head assembly 4, and includes a machine tool spindle 31, a spindle drive mechanism, and a rotary chuck 33. The machine tool spindle 31 is a hollow cylindrical shape and is arranged laterally on one side of the hopper 21. The spindle drive mechanism includes a drive motor 32, which is connected to the machine tool spindle 31 via a belt and is used to drive the machine tool spindle 31 to rotate. The rotary chuck 33 is fixed to one end of the machine tool spindle 31 near the cyclone milling head assembly 4 and is coaxial with the machine tool spindle 31. Furthermore, a guide cylinder 34 is inserted into the shaft hole of the machine tool spindle 31. The guide cylinder 34 is hollow and the inner hole of the guide cylinder 34 is slightly larger than the outer diameter of the workpiece. One end of the guide cylinder 34 is adjacent to the support plate 223 and the other end extends into the rotary chuck 33 and is adjacent to the chuck of the rotary chuck 33, so that the workpiece on the support plate 223 enters the rotary chuck 33 through the guide cylinder 34 and is clamped and fixed by the chuck.

[0035] like Figure 7 , Figure 8 As shown, the cyclone milling head assembly 4 includes a slide 41, a transverse drive mechanism, a moving table 42, a lifting drive mechanism, and a cyclone milling head 43. The slide 41 is slidably connected to the machine bed 1. The transverse drive mechanism drives the slide 41 to reciprocate laterally relative to the machine bed 1. The moving table 42 is slidably connected to the slide 41, and the lifting drive mechanism drives the moving table 42 to move up and down relative to the slide 41. The cyclone milling head 43 is mounted on the moving table 42, allowing it to move laterally and vertically relative to the machine bed 1. The tailstock mechanism 5 includes a second drive component 52, a mounting base 53, and a center point 51. The center point 51 is fixed to the mounting base 53, so that the center point 51 is opposite to the machine tool spindle 31 and located on the same axis. The second drive component 52 is fixed to the slide 41 via a mounting bracket 54 and connected to the mounting base 53, driving the second drive component 52, the center point 51, and the mounting base 53 to reciprocate laterally. In this embodiment, the second driving component 52 is a hydraulic cylinder, and a pressure reducing valve and a back pressure valve are provided in the oil circuit of the hydraulic cylinder to ensure that the center 51 applies a basically constant pressure to the workpiece, thus ensuring the stability of the workpiece fixation. Moreover, when the slide 41 drives the cyclone milling head 43 and the second driving component 52 to feed towards one end of the machine tool spindle 31, the hydraulic cylinder can unload oil and retract the piston rod. The amount of retraction is equivalent to the feed amount of the slide 41, so that the center 51 remains stationary relative to the rotating chuck 33 and the workpiece, ensuring a stable fit between the center 51 and the workpiece.

[0036] Furthermore, in this embodiment, the mounting base 53 and the movable stage 42 are connected by a cross slide mechanism 57, which improves the stability of the mounting base 53 and avoids interference between the mounting base 53 and the movable stage 42. Specifically, the cross slide mechanism 57 includes a first slide rail 55, a first slide block 56, a slide table 57, a second slide rail 58, and a second slide block 59. The first slide rail 55 is vertically mounted on the movable stage 42, and the slide table 57 is slidably connected to the first slide rail 55 via the first slide block 56. The second slide rail 58 is horizontally mounted on the slide table 57, and the second slide block 59 is slidably engaged with the second slide rail 58 and fixedly connected to the mounting base 53. In this embodiment, there are two first slide rails 55 spaced apart, and two second slide blocks 59 corresponding one-to-one with the two slide rails. Meanwhile, the mounting bracket 54 is located behind the slide table 57, and one side of the mounting bracket 54 is fixedly connected to the slide table 57 to further improve the stability of the mounting base 53.

[0037] The working process of this utility model is as follows: The short workpiece to be processed is stacked in the hopper 21. The lifting mechanism drives the pallet 223 to rise and fall, so that the workpiece enters the drop groove 223a of the pallet 223 through the discharge channel 21b and is lifted to the top of the hopper 21, and the workpiece is aligned with the guide cylinder 34 on the machine tool spindle 31. Then, the push rod 233 pushes the workpiece along the guide cylinder 34 into the rotating clamp 33 and is clamped by the rotating clamp 33. Then, the slide plate 41 drives the cyclone milling head 43 and the tailstock mechanism 5 to move towards the workpiece side. The second drive 52 also drives the center 51 to move forward, so that the center 51 abuts against the tail of the workpiece, completing the loading and fixing of the workpiece; then the slide plate 41 continues to drive the cyclone milling head 43 to feed towards the side of the machine tool spindle 31, so that the cyclone milling head 43 performs cutting processing on the workpiece. At the same time, the piston rod of the second drive 52 retracts, so that the center 51 remains stationary and maintains a stable fit with the tail of the workpiece until the processing is completed. Then the slide plate 41 returns to its original position and drives the cyclone milling head 43 and the tailstock mechanism 5 away from the workpiece. The rotating chuck 33 releases the workpiece, completing the unloading.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0039] Although this document frequently uses terms such as bed 1, loading area 1a, processing area 1b, loading mechanism assembly 2, hopper 21, machine tool spindle 31, rotary chuck 33, and tailstock mechanism 5, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
