Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and more specifically to a processing equipment for annular isolator cavities. Background Technology

[0002] A ring isolator is a multi-port device that directs incident waves entering any of its ports to the next port in a sequential direction determined by a static deflection magnetic field. Milling of ring isolators is a core step in precision machining, mainly used for shaping the internal structure of cavities. It typically employs layered milling to gradually remove excess material, rapidly bringing the workpiece dimensions close to the final design contour. This process is achieved through a large depth of cut and feed rate, which can significantly shorten machining time and improve overall efficiency. For circular cavities, a three-jaw chuck with locating pins is used to ensure coaxiality between the rotation center and the machine tool spindle.

[0003] Currently, during the processing of annular isolators, the workpiece is cut by a milling cutter. The metal material is prone to plastic deformation, and the chips form burrs due to the material's ductility when separated. These burrs hinder the fit between the annular isolator cavity and other components, leading to assembly difficulties. Furthermore, the chips generated during milling tend to adhere to the inner wall of the annular isolator cavity. These tiny chips reduce the surface finish of the cavity, affecting the appearance and functionality of the workpiece. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a ring isolator cavity processing equipment, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a processing device for annular isolator cavities, comprising:

[0007] A machine tool, wherein a cutting part and a conveying part are fixedly connected to the upper surface of the machine tool respectively;

[0008] The conveying unit includes a conveying frame, the lower surface of which is fixedly connected to the upper surface of the machine base. A sliding base plate is slidably connected to the top of the inner wall of the conveying frame. A vertical rod is fixedly connected to the upper surface of the sliding base plate. A middle block is fixedly connected to the outer circumference of the vertical rod. A top block is fixedly connected to the top of the vertical rod. Two middle blocks and two top blocks are provided. A rotating shaft is rotatably connected to the center of each of the two top blocks. The ends of the two rotating shafts that are close to each other pass through the side wall of the top block and are fixedly connected to a top plate. A three-jaw clamp is fixedly connected to the upper surface of the top plate. A telescopic sleeve is fixedly connected to the upper surface of the sliding base plate. A telescopic rod is slidably connected to the inner wall of the telescopic sleeve. A rotating block is rotatably connected to the top of the telescopic rod. A scraping frame is fixedly connected to the top of the rotating block.

[0009] Furthermore, a drive motor is fixedly connected to the outer surface of the conveyor frame, and a screw is rotatably connected to the inner wall of the conveyor frame. The output end of the drive motor is fixedly connected to one end of the screw, and a slider is threaded onto the outer circumference of the screw. The slider is fixedly connected to the outer circumference of the upright.

[0010] Furthermore, connecting strips are fixedly connected to both sides of the conveyor frame, and a first limiting strip, a second limiting strip, and a third limiting strip are fixedly connected to the upper surface of the connecting strips respectively. A limiting block is fixedly connected to the outer circumference of the rotating shaft.

[0011] Furthermore, a first rack and a second rack are fixedly connected to the upper surface of the connecting strip, and a first gear is fixedly connected to the outer circumferential surface of the rotating shaft.

[0012] Furthermore, a return spring is fixedly connected between the bottom end of the telescopic rod and the bottom of the inner wall of the telescopic sleeve.

[0013] Furthermore, a ring is fixedly connected to the outer circumference of the telescopic rod, a bottom wheel is fixedly connected to the bottom of the ring, and a crossbar is fixedly connected to the side of the two middle blocks that are close to each other. The outer circumference of the two crossbars is slidably connected to a pusher bracket.

[0014] Furthermore, the bottom of the pushing inclined frame is rotatably connected to a pulley, and the inner wall of the conveying frame is fixedly connected to an adjusting slide rail, with the pulley slidably connected inside the adjusting slide rail.

[0015] Furthermore, the adjusting slide rail includes a first track, a second track, and an inclined rail, with the first track and the second track being fixedly connected via the inclined rail.

[0016] Furthermore, a second gear is fixedly connected to the outer circumference of the rotating block, and a connecting ridge is fixedly connected to the inner wall of the conveying frame. The protrusion of the connecting ridge is provided with a toothed tooth row.

[0017] Furthermore, the side of the scraping frame is arc-shaped, and a slot is formed on the outer surface of the scraping frame. A telescopic scraper is slidably connected to the inner wall of the slot, and a telescopic spring is fixedly connected between the telescopic scraper and the slot.

[0018] The technical solution provided by this invention has the following advantages compared with the prior art:

[0019] This invention utilizes a scraping frame. First, by controlling the rotating shaft to rotate 180 degrees around its own axis, the three-jaw chuck drives the workpiece to rotate 180 degrees downwards around the rotating shaft, so that the opening of the workpiece cavity faces directly downwards. At this point, the opening of the workpiece cavity is aligned with the scraping frame (the opening of the workpiece cavity is directly above the scraping frame). Then, by controlling the scraping frame to move vertically upwards, the scraping frame extends deeper into the interior of the workpiece cavity, with the top of the scraping frame in contact with the top of the inner wall of the workpiece cavity. Finally, by controlling the rotating block to rotate around its own axis, the rotating block drives the scraping frame to rotate around the axis of the workpiece cavity. Under the rotation of the scraping frame, the scraping frame scrapes away burrs on the inner wall of the workpiece cavity, preventing burrs from hindering the workpiece's fit with other components, thereby reducing the assembly difficulty of the workpiece. Furthermore, under the action of gravity, the scraped burrs and debris on the inner wall of the cavity fall downwards through the cavity opening, separating the scraped burrs and debris from the inner wall of the cavity, thereby improving the surface finish of the cavity and thus improving the appearance and functionality of the workpiece.

[0038] The upper surface of the connecting bar 4 is fixedly connected to the first rack 45 and the second rack 46 respectively, and the outer circumferential surface of the rotating shaft 24 is fixedly connected to the first gear 47.

[0039] A return spring 5 is fixedly connected between the bottom end of the telescopic rod 26 and the bottom of the inner wall of the telescopic sleeve 261.

[0042] The adjusting slide rail 65 includes a first track 651, a second track 652 and an inclined rail 653, with the first track 651 and the second track 652 being fixedly connected by the inclined rail 653.

[0044] The sides of the scraping frame 28 are curved, and a slot 281 is provided on the outer surface of the scraping frame 28. A telescopic scraper 282 is slidably connected to the inner wall of the slot 281, and a telescopic spring 283 is fixedly connected between the telescopic scraper 282 and the slot 281.

[0045] Working principle:

[0046] The cutting process of the workpiece:

[0047] In practical applications, initially, the sliding base plate 21 is positioned on the side of the conveyor frame 2 closest to the drive motor 3, ensuring sufficient workpiece clamping space and easy operation. The workpiece to be processed is placed on the three-jaw chuck 251, and the workpiece is reliably locked by controlling the clamping mechanism of the three-jaw chuck 251 (such as hydraulic, pneumatic, or manual), ensuring no displacement of the workpiece during processing. The drive motor 3 is started, and its output end is connected to the screw 31 through a coupling (or other transmission components), driving the screw 31 to rotate forward on the inner wall of the conveyor frame 2. The rotating screw 31 drives the slider 32 on its outer circumference to move along the axis of the screw 31. The slider 32 is fixedly connected to the upright 211 by welding, thereby driving the sliding base plate 21 to move along the conveyor frame 2. The bottom of the inner wall of the conveyor 2 moves toward the cutting section 11. The sliding base plate 21 drives two top blocks 23 to move toward the cutting section 11 via the upright 211. A rotating shaft 24 is provided at the center of the top block 23, and the rotating shaft 24 is connected to the top plate 25. The movement of the top block 23 drives the top plate 25 to move toward the cutting section 11. When the top plate 25 moves to the vicinity of the cutting position, the bottom side of the limiting block 44 contacts the top of the third limiting strip 43. The third limiting strip 43 is fixed to the conveyor 2 via the connecting strip 4. Under the limiting action of the third limiting strip 43, the rotating shaft 24 is prevented from rotating around its own axis, ensuring the stability of the top plate 25 and the workpiece during the cutting process. The top plate 25 drives the workpiece to the cutting position of the cutting section 11 via the three-jaw clamp 251 on its upper surface (e.g., Figure 2 As shown in the figure, at this time, the relative position of the workpiece and the milling cutter meets the processing requirements. The cutting part 11 controls the milling cutter to cut the workpiece at the cutting position. During the cutting process, the milling cutter adopts the layered milling method, that is, according to the predetermined cutting depth and feed rate, the excess material on the workpiece is gradually removed. This layered milling method can effectively control the cutting force, reduce tool wear, and at the same time quickly bring the workpiece size close to the final design contour, thereby improving processing efficiency and accuracy.

[0048] As a further embodiment of the present invention, during the cutting process, the cutting state of the workpiece, such as cutting force, cutting temperature, and changes in workpiece size, can be monitored in real time by sensors (such as displacement sensors, force sensors, etc.). Based on the monitoring data, the cutting parameters (such as cutting speed, feed rate, and depth of cut) can be adjusted in a timely manner to ensure machining quality and equipment safety.

[0049] The rotation process of the workpiece:

[0050] In practical applications, after milling is completed, the drive motor 3 drives the screw 31 to rotate in the opposite direction. The rotating screw 31 drives the sliding base plate 21 to move along the bottom of the inner wall of the conveyor frame 2 towards the drive motor 3 via the slider 32. The sliding base plate 21 drives the four uprights 211 on its upper surface to move towards the drive motor 3. The four uprights 211 drive the two top blocks 23 at their tops to move towards the drive motor 3. The two top blocks 23 drive the rotating shaft 24 at its center to move towards the drive motor 3. The two rotating shafts 24 drive the limiting blocks 44 on their outer circumference to move along the upper surface of the third limiting strip 43 towards the drive motor 3. After the two limiting blocks 44 separate from the two third limiting strips 43, the rotation restriction of the rotating shafts 24 by the third limiting strips 43 is released. The two top blocks 23 continue to drive the two rotating shafts 24 to move. The two rotating shafts 24 drive the first gear on their outer circumference. 47 meshes with the second rack 46. Under the meshing action of the first gear 47 and the second rack 46, the two first gears 47 drive the two rotating shafts 24 to rotate around their own axes. The two rotating shafts 24 drive the top plate 25 to rotate synchronously. The top plate 25 drives the workpiece to rotate around the axis of the rotating shaft 24 through the three-jaw clamp 251. After the two first gears 47 drive the two rotating shafts 24 and the workpiece to rotate 180 degrees, the opening of the workpiece cavity faces directly downward. At this time, the opening of the workpiece cavity is aligned with the scraping frame 28 (the opening of the workpiece cavity is located directly above the scraping frame 28). The two top blocks 23 continue to drive the two rotating shafts 24 to move. The two rotating shafts 24 drive the limiting blocks 44 on their outer circumference to move along the upper surface of the second limiting strip 42 toward the drive motor 3. Under the limiting action of the second limiting strip 42, the rotating shafts 24 are prevented from rotating around their own axes.

[0051] The upward movement of the scraping frame 28:

[0052] In practical applications, the sliding base plate 21 continues to move along the bottom of the inner wall of the conveyor frame 2 towards the drive motor 3. The sliding base plate 21 drives the two middle blocks 22 to move towards the drive motor 3 via four uprights 211. The two middle blocks 22 drive the inclined frame 63 to move towards the drive motor 3 via two crossbars 62. The inclined frame 63 drives the pulley 64 at its bottom to move towards the drive motor 3 along the first track 651. After the pulley 64 is slidably connected to the inclined rail 653 along the first track 651, under the guidance of the inclined rail 653, the pulley 64 drives the inclined frame 63 to move along the axis of the crossbar 62 towards the screw 31. The moving inclined frame 63 pushes the bottom wheel 61 and the straight ring 6 to move vertically upward through its inclined section. The ring 6 drives the telescopic rod 26 on its inner wall to move upward along the axis of the telescopic sleeve 261. The telescopic rod 26 drives the rotating block 27 at its top to move vertically upward. The rotating block 27 drives the scraping frame 28 at its top to move vertically upward, so that the scraping frame 28 moves upward into the interior of the workpiece cavity. After the pulley 64 slides along the inclined rail 653 and the second rail 652, under the limiting action of the second rail 652, the position of the pushing inclined frame 63 on the crossbar 62 is fixed. At this time, the pushing inclined frame 63 contacts the two bottom wheels 61 through its upper horizontal section, thereby fixing the height of the scraping frame 28 and ensuring that the top of the scraping frame 28 is in contact with the top of the inner wall of the workpiece cavity.

[0053] The rotation process of scraping frame 28:

[0054] In practical applications, the sliding base plate 21 continues to drive the telescopic sleeve 261 on its upper surface to move towards the drive motor 3. The telescopic sleeve 261 drives the telescopic rod 26 on its inner wall to move towards the drive motor 3. The telescopic rod 26 drives the rotating block 27 at its top to move towards the drive motor 3. The rotating block 27 drives the second gear 7 on its outer circumference to move towards the toothed rack 72. After the second gear 7 meshes with the toothed rack 72, under the meshing action of the second gear 7 and the toothed rack 72, the second gear 7 drives the rotating block 27 to rotate around its own axis. The rotating block 27 drives the scraping frame 28 at its top to rotate around the axis of the workpiece cavity. Under the rotation action of the scraping frame 28, the "cross" (such as...) at the top of the scraping frame 28... Figure 5 As shown, the scraping frame 28 rotates along the top of the inner wall of the workpiece cavity. The "cross" scrapes away the burrs on the top of the inner wall of the workpiece cavity. The four sides of the scraping frame 28 are set with arc surfaces, so that the four arc surfaces of the scraping frame 28 rotate along the inner circumferential surface of the workpiece cavity. The scraping frame 28 scrapes away the burrs on the inner circumferential surface of the workpiece cavity through its four vertical sections, preventing the burrs on the workpiece cavity from hindering the cooperation between the workpiece and other parts, thereby reducing the assembly difficulty of the workpiece.

[0055] As a further embodiment of the present invention, during the process of the scraping frame 28 rotating along the inner wall of the workpiece cavity, since the opening of the cavity is always set downward, under the action of gravity, the scraped burrs and debris on the inner wall of the cavity fall downward through the opening of the cavity, so that the scraped burrs and debris are separated from the inner wall of the cavity, thereby improving the smoothness of the cavity surface and thus improving the appearance and functionality of the workpiece.

[0056] As a further embodiment of the present invention, during the process of the scraping frame 28 driving the four telescopic scraper strips 282 to rotate, under the action of centrifugal force, the four telescopic scraper strips 282 move along the inner wall of the slot 281 toward the inner wall of the workpiece cavity, thereby ensuring that the four telescopic scraper strips 282 rotate along the inner wall of the workpiece cavity.

[0057] The workpiece reset process:

[0058] In practical applications, the sliding base plate 21 continues to move toward the drive motor 3, and the pulley 64 moves toward the drive motor 3 along the second track 652. After the pulley 64 slides along the second track 652 and the inclined rail 653, under the guidance of the inclined rail 653, the pulley 64 drives the pusher frame 63 to move away from the screw 31 along the axis of the crossbar 62, releasing the limiting effect of the pusher frame 63 on the bottom wheel 61. Under the elastic action of the return spring 5, the return spring 5 pulls the telescopic rod 26 to move downward along the axis of the telescopic sleeve 261. The telescopic rod 26 drives the rotating block 27 and the scraping frame 28 to move vertically downward, so that the scraping frame 28 is separated from the workpiece cavity (so that the rotating shaft 24 drives the workpiece to rotate around the axis of the rotating shaft 24).

[0059] As a further embodiment of the present invention, the sliding base plate 21 continues to drive the rotating shafts 24 to move toward the drive motor 3. The two rotating shafts 24 drive the limiting blocks 44 on their outer circumference to move toward the drive motor 3 along the upper surface of the second limiting strips 42. After the two limiting blocks 44 separate from the two second limiting strips 42, the rotation restriction of the rotating shafts 24 by the second limiting strips 42 is released. The two top blocks 23 continue to drive the two rotating shafts 24 to move. The two rotating shafts 24 drive the first gear 47 on their outer circumference to mesh with the first rack 45. Under the meshing action of the first gear 47 and the first rack 45, the two first gears 47 drive the two rotating shafts 24 to rotate around their own axes. The two rotating shafts 24 drive the first gear 47 to rotate around their own axes. The top plate 25 rotates synchronously, and the top plate 25 drives the workpiece to rotate around the axis of the rotating shaft 24 through the three-jaw clamp 251. After the two first gears 47 drive the two rotating shafts 24 and the workpiece to rotate 180 degrees, the opening of the workpiece cavity faces directly upward. The two top blocks 23 continue to drive the two rotating shafts 24 to move. The two rotating shafts 24 drive the limiting blocks 44 on their outer circumference to move along the upper surface of the first limiting strip 41 towards the drive motor 3. Under the limiting action of the first limiting strip 41, the rotating shafts 24 are prevented from rotating around their own axis, thereby ensuring that the opening of the workpiece cavity is always facing upward. By controlling the three-jaw clamp 251 to unlock, the processed workpiece cavity is taken out from the three-jaw clamp 251.
