Description

Technical Field

[0001] This invention relates to the field of milling equipment, specifically a multi-axis milling composite machining center. Background Technology

[0002] A multi-axis milling machining center is a mechanical device that uses a milling cutter to mill workpieces. When machining gears, a machining center is often used to mill straight grooves to create keyways, facilitating subsequent gear assembly.

[0003] However, existing multi-axis milling machining centers often use manual clamping to fix gear workpieces when milling grooves. This operation mode not only increases the labor intensity of operators, but also takes a long time to fix, which seriously affects the efficiency of milling. In addition, after the milling process is completed, the gear workpiece still needs to be unloaded by workers and neatly placed in the material tray, which further increases the workload of operators. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a multi-axis milling composite machining center.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-axis milling composite machining center, comprising a machining center and a workpiece table disposed inside the machining center. A material ejector is disposed at the upper end of the workpiece table, and a support ring is mounted at the end of the material ejector. A fixed clamping ring extends from the upper edge of the support ring, and an extension frame extends from the side of the support ring. A movable clamping ring is slidably mounted on the extension frame. The movable clamping ring and the fixed clamping ring are symmetrically arranged. Both the fixed and movable clamping rings have protruding teeth extending from their opposing surfaces. The protruding teeth are adapted to the tooth grooves of the gear workpiece. A guide sleeve is fixedly mounted at the end of the extension frame. A guide rod is elastically mounted inside the guide sleeve, and the guide rod extends through the rear end of the guide sleeve. A push clamping frame is rotatably mounted between the end of the guide rod and the movable clamping ring. A positioning frame is disposed behind the guide rod and is fixed to the workpiece table. A material pusher is disposed at the front end of the machining center.

[0006] Preferably, a T-shaped slider extends from the lower side of the movable clamping ring. The T-shaped slider is slidably installed inside the extension frame. A second return spring is fixedly installed at the front end of the inner side of the guide sleeve. The end of the second return spring is fixed to the guide rod.

[0007] Preferably, the discharge component includes a second servo slide fixedly installed on the upper end of the workpiece table. A movable frame is fixedly installed on the upper end of the slide of the second servo slide. A bearing shaft is rotatably installed through the end of the movable frame. The rear end of the bearing shaft is fixed to a support ring. A limiting frame extends from the side of the movable frame. The end of the limiting frame is attached to the lower end of the extension frame. A pressure roller is installed on the side of the guide sleeve. A pressure frame extends from the upper edge of the positioning frame.

[0008] Preferably, an adjusting gear is coaxially fixedly installed at the front end of the bearing shaft, and an adjusting toothed plate is meshed on the side of the adjusting gear. A sliding lug is fixedly installed on the side of the movable frame in front of the limiting frame. The end of the sliding lug is T-shaped. The adjusting toothed plate is slidably installed on the end of the sliding lug. An adjusting wheel is installed on the lower side of the adjusting toothed plate.

[0009] Preferably, a slot frame is fixedly installed at the lower end of the support ring, and a column is slidably installed through the middle of the lower end of the slot frame. A guide post extends coaxially from the upper end of the column, and the center line of the guide post is collinear with the center line of the support ring. The diameter of the guide post is adapted to the inner diameter of the gear workpiece. A guide frame is fixedly installed at the lower end of the column, and the guide frame is slidably installed in the groove of the slot frame. Push rollers are installed on both sides of the guide frame, and a double-headed inclined push rail is provided behind the push rollers. The double-headed inclined push rail is fixed to the positioning frame.

[0010] Preferably, a first return spring is wound around the outside of the column, one end of the first return spring is fixed to the lower end of the guide column, and the other end of the first return spring is fixed to the lower inner end of the slot frame.

[0011] Preferably, the rear end of the support ring extends to a locking tongue, and a locking seat is provided behind the locking tongue, with the rear end of the locking seat fixed to the positioning frame.

[0012] Preferably, the pusher includes a first servo slide fixedly installed at the front end of the machining center. Two push rods are symmetrically fixedly installed on the upper end of the first servo slide. A support is fixedly installed at the front end of the machining center on the side of the first servo slide. An extension frame is fixedly installed at the front end of the support. Two adjustment rails extend from the upper rear edge of the extension frame. The two adjustment rails are arranged in parallel.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The movable support ring moves the gear workpiece toward the milling station. During the movement, the guide rod abuts against the positioning frame, causing the guide rod to gradually enter the guide sleeve. At this time, the retracting guide rod drives the push clamp to move, pushing the movable clamping ring and causing it to move laterally to clamp the gear workpiece between the fixed clamping ring and the movable clamping ring. Simultaneously, the protruding teeth on the fixed and movable clamping rings engage with the tooth grooves of the gear workpiece, thus pushing the gear workpiece to the milling station while firmly fixing it. Then, the straight groove can be milled to form a keyway on the gear workpiece. This process does not require manual clamping by the operator, effectively reducing the labor intensity of the workers and improving milling efficiency.

[0014] 2. After milling, the second servo slide moves the moving frame forward to extend the gear workpiece from the machining center. Just before reaching the end of its stroke, the adjusting wheel enters between two adjusting rails, guiding it upwards and causing the adjusting gear plate to move upwards, thus rotating the adjusting gear. This causes the support ring on the bearing shaft to rotate, turning it 90 degrees. After the rotation, the support ring is positioned at the end of the extended stroke, while the gear workpiece is on the side of the tray. Then, the first servo slide moves the push rod laterally, passing through the support ring to push the gear workpiece. The pushed gear workpiece slides on the guide post, gradually entering the tray. After entering the tray, a gap remains between the gear workpiece and the inner wall of the tray. Continuing to push the gear workpiece separates it from the guide post, allowing it to fall into the tray and complete the unloading process. This process is repeated, allowing the workpiece to be automatically unloaded and neatly placed in the tray after milling. This process further reduces the labor intensity of workers and improves milling efficiency.

[0015] 3. When the support ring moves the gear workpiece toward the milling station, the pusher on the guide frame will contact the double-headed inclined pusher rail and move down under the guidance of the double-headed inclined pusher rail, thereby driving the column and guide column to move down synchronously, so as to pull the guide column out of the inside of the gear workpiece, so that the inner wall of the gear workpiece can be fully exposed, avoiding obstruction during milling, thus ensuring the smooth progress of milling.

[0018] 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.

[0019] This invention provides a technical solution: such as Figures 1-11The multi-axis milling machining center shown includes a machining center 1 and a workpiece table 2 disposed inside the machining center 1. Since milling straight grooves on a gear workpiece 11 using the machining center 1 to form a keyway is existing technology and widely used, it is not described in detail here. A material ejector is provided at the upper end of the workpiece table 2, and a support ring 9 is installed at the end of the material ejector. The support ring 9 supports the gear workpiece 11. A fixing clamping ring 29 extends from the upper edge of the support ring 9, and an extension bracket 26 extends from the side of the support ring 9. A movable clamping ring 30 is slidably mounted on the extension bracket 26. The fixed clamping ring 29 and the movable clamping ring 30 serve to clamp and fix the gear workpiece 11. The movable clamping ring 30 and the fixed clamping ring 29 are symmetrically arranged. The opposing surfaces of the fixed clamping ring 29 and the movable clamping ring 30 both extend with protruding teeth 38. The protruding teeth 38 are adapted to the tooth groove of the gear workpiece 11, which can ensure that the protruding teeth 38 and the tooth groove of the gear workpiece 11 can be smoothly engaged. Under the engagement action of the protruding teeth 38, the restriction on the gear workpiece 11 can be strengthened, so that the gear workpiece 11 is firmly fixed. A guide sleeve 2 is fixedly installed at the end of the extension bracket 26. 8. A guide rod 27 is elastically installed inside the guide sleeve 28. The guide sleeve 28 serves to allow the guide rod 27 to slide. The guide rod 27 extends through the rear end of the guide sleeve 28. A pusher 20 is rotatably mounted between the end of the guide rod 27 and the movable clamping ring 30. A positioning frame 4 is set behind the guide rod 27. The positioning frame 4 is fixed to the workpiece table 2. A pusher is set at the front end of the machining center 1. Through the moving support ring 9, the gear workpiece 11 can be moved towards the milling station. During the movement, the guide rod 27 will abut against the positioning frame 4, causing the guide rod 27 to gradually enter the guide sleeve 28. At this time, the retracting guide... The lever 27 drives the push clamp 20 to move, pushing the movable clamping ring 30 to move laterally, clamping the gear workpiece 11 between the fixed clamping ring 29 and the movable clamping ring 30. At the same time, the protruding teeth 38 on the fixed clamping ring 29 and the movable clamping ring 30 engage with the tooth groove of the gear workpiece 11, thus pushing the gear workpiece 11 to the milling station while firmly fixing the gear workpiece 11. Then, the straight groove can be milled to form a keyway on the gear workpiece 11. The process does not require manual clamping by the operator, effectively reducing the labor intensity of the workers and improving the milling efficiency.

[0020] A T-shaped slider 31 extends from the lower side of the movable clamping ring 30. The T-shaped slider 31 is slidably installed inside the extension frame 26 and serves to guide the movable clamping ring 30. A second return spring 37 is fixedly installed at the front end of the inner side of the guide sleeve 28. The end of the second return spring 37 is fixed to the guide rod 27. The second return spring 37 restores its deformation to push the movable clamping ring 30 to reset and loosen the clamping of the gear workpiece 11.

[0021] The output component includes a second servo slide 6 fixedly installed on the upper end of the workpiece table 2. A movable frame 12 is fixedly installed on the upper end of the slide of the second servo slide 6. The second servo slide 6 drives the movable frame 12 to move. A bearing shaft 22 is rotatably installed through the end of the movable frame 12. The movable frame 12 supports the bearing shaft 22. The rear end of the bearing shaft 22 is fixed to the support ring 9. A limit frame 17 extends from the side of the movable frame 12. The end of the limit frame 17 is attached to the lower end of the extension frame 26. The limit frame 17 can limit the support ring 9 so that it will not rotate on its own. A pressure roller 10 is installed on the side of the guide sleeve 28. A pressure frame 5 extends from the upper edge of the positioning frame 4. The pressure roller 10 contacts the pressure frame 5 and rolls along the lower end of the pressure frame 5 so that the extension frame 26 can be firmly attached to the limit frame 17 under the pressure of the pressure frame 5, so that the support ring 9 remains horizontal and cannot rotate.

[0022] An adjusting gear 23 is coaxially fixedly installed at the front end of the bearing shaft 22. An adjusting toothed plate 24 meshes with the side of the adjusting gear 23. The adjusting toothed plate 24 drives the adjusting gear 23 to rotate. A sliding lug 19 is fixedly installed on the side of the moving frame 12 in front of the limiting frame 17. The end of the sliding lug 19 is T-shaped. The adjusting toothed plate 24 is slidably installed on the end of the sliding lug 19. The sliding lug 19 guides the adjusting toothed plate 24. An adjusting wheel 25 is installed on the lower side of the adjusting toothed plate 24.

[0023] A slot frame 39 is fixedly installed at the lower end of the support ring 9. A column 14 is slidably installed through the middle of the lower end of the slot frame 39. A guide post 18 extends coaxially from the upper end of the column 14. The cooperation between the slot frame 39 and the column 14 guides the guide post 18, which guides the gear workpiece 11 so that it will not fall off during the flipping process. At the same time, it ensures that the gear workpiece 11 moves smoothly into the material tray 33 when pushed. The center line of the guide post 18 is collinear with the center line of the support ring 9. The diameter of the guide post 18 is matched with the inner diameter of the gear workpiece 11, which ensures that the guide post 18 passes smoothly through the interior of the gear workpiece 11. A guide post 18 is fixedly installed at the lower end of the column 14. The guide frame 15 is slidably installed in the groove of the slot frame 39 to ensure that the guide frame 15 will not rotate. Push rollers 16 are installed on both sides of the guide frame 15, and a double-headed inclined push rail 21 is set behind the push rollers 16. The double-headed inclined push rail 21 is fixed to the positioning frame 4. When the support ring 9 moves the gear workpiece 11 toward the milling station, the push rollers 16 on the guide frame 15 will contact the double-headed inclined push rail 21 and move down under the guidance of the double-headed inclined push rail 21, thereby driving the column 14 and the guide column 18 to move down synchronously, so as to pull the guide column 18 out of the inside of the gear workpiece 11, so that the inner wall of the gear workpiece 11 can be fully exposed, avoiding obstruction during milling, thus ensuring the smooth progress of milling.

[0024] A reset spring 13 is wound around the outside of the column 14. One end of the reset spring 13 is fixed to the lower end of the guide column 18, and the other end of the reset spring 13 is fixed to the lower inner end of the slot frame 39. The reset spring 13 serves to move the guide column 18 upward and reset it.

[0025] The rear end of the support ring 9 extends to a locking tongue 8, and a locking seat 7 is provided behind the locking tongue 8. The rear end of the locking seat 7 is fixed to the positioning frame 4. The locking tongue 8 on the support ring 9 and the locking seat 7 are engaged, which can further lock the support ring 9 and keep it horizontal and unable to rotate.

[0026] The pusher includes a first servo slide 3 fixedly installed at the front end of the machining center 1. Two push rods 36 are symmetrically fixedly installed on the upper part of the slide of the first servo slide 3. The first servo slide 3 can drive the push rods 36 to move laterally so as to push the gear workpiece 11 through the support ring 9 and push it into the material tray 33. A support 32 is fixedly installed at the front end of the machining center 1 on the side of the first servo slide 3. The support 32 plays the role of supporting and positioning the material tray 33. An extension frame 34 is fixedly installed at the front end of the support 32. Two adjusting inclined rails 35 extend from the upper edge of the rear end of the extension frame 34. The extension frame 34 plays the role of fixing the adjusting inclined rails 35. The two adjusting inclined rails 35 are arranged in parallel. The adjusting inclined rails 35 can guide the adjusting wheel 25 to move upward, thereby driving the adjusting gear plate 24 to move upward.

[0027] During milling, the gear workpiece 11 is placed on the support ring 9. At this time, the guide post 18 passes through the inside of the gear workpiece 11, and the fixing ring 29 is attached to the gear workpiece 11. At the same time, the protruding teeth 38 on the fixing ring 29 are engaged in the tooth grooves on the gear workpiece 11 to limit the gear workpiece 11. Then, the second servo slide 6 drives the moving frame 12 to move backward, which in turn drives the support ring 9 to move backward, so as to send the gear workpiece 11 to the milling station. During this process, the pressure roller 10 will first contact the pressure frame 5 and roll along the lower end of the pressure frame 5 so that under the pressure of the pressure frame 5, the extension frame 26 can be firmly attached to the limiting frame 17, so that the support ring 9 remains horizontal and cannot rotate. Then it continues to move backward. At this time, the push roller 16 on the guide frame 15 will contact the double-headed inclined push rail 21 and move backward. Guided by the push rail 21, the column 14 and guide column 18 move downwards simultaneously, pulling the guide column 18 out of the gear workpiece 11 and fully exposing the inner wall of the gear workpiece 11 to avoid obstruction during milling. It then continues to move backwards, at which point the guide rod 27 abuts against the positioning frame 4, gradually entering the guide sleeve 28. The retracting guide rod 27 drives the push clamp frame 20 to move, pushing the movable clamping ring 30 and causing it to move laterally, clamping the gear workpiece 11 between the fixed clamping ring 29 and the movable clamping ring 30. Simultaneously, the protruding teeth 38 on the fixed clamping ring 29 and the movable clamping ring 30 engage with the tooth grooves of the gear workpiece 11, thus firmly fixing the gear workpiece 11 during the milling process. The locking tongue 8 on the time support ring 9 engages with the locking seat 7 to further lock the support ring 9, keeping it horizontal and preventing it from rotating. Then, the gear workpiece 11 can be milled with a straight groove by the machining center 1 to form a keyway. After milling, the second servo slide 6 moves the moving frame 12 forward to extend the gear workpiece 11 from the machining center 1. During this process, the second return spring 37 returns to its original shape, pushing the movable clamping ring 30 to reset and loosen the clamping of the gear workpiece 11. Simultaneously, the first return spring 13 also returns to its original shape, causing the guide post 18 to move upward and reset, passing back into the gear workpiece 11. The pressure roller 10 separates from the pressure frame 5. Just before extending to the end of its stroke, the adjusting wheel 25 enters between the two adjusting inclined rails 35. Guided by the adjusting inclined rail 35, the adjusting wheel 25 is driven to move upward, which in turn drives the adjusting gear plate 24 to move upward, thereby pushing the adjusting gear 23 to rotate. This drives the support ring 9 on the bearing shaft 22 to rotate, causing it to rotate 90 degrees. After the rotation is completed, the support ring 9 is just at the end of its extended stroke. At the same time, the gear workpiece 11 is located on the side of the material tray 33. Then, the first servo slide 3 drives the push rod 36 to move laterally, so as to push the gear workpiece 11 through the support ring 9. At this time, the pushed gear workpiece 11 will slide on the guide post 18 to gradually enter the material tray 33. After the gear workpiece 11 enters the material tray 33, there is a gap between the gear workpiece 11 and the inner wall of the material tray 33. At this time, the gear workpiece 11 is pushed to separate the gear workpiece 11 from the guide post 18.The material is then placed into the material tray 33 for unloading. This process is repeated to ensure that after milling, the material is automatically unloaded and neatly placed in the material tray 33. Then, the second servo slide 6 drives the moving frame 12 to move backward and reset to the loading position. During this process, the adjusting rail 35 drives the adjusting wheel 25 downward, allowing the support ring 9 to return to a horizontal state. Simultaneously, the limiting frame 17 supports the extending frame 26. Then, the next gear workpiece 11 to be milled can be placed on the support ring 9, and this cycle is repeated for milling.
