Description

Technical Field

[0001] This invention relates to the field of deep hole machining technology, and more specifically, to a deep hole machining equipment and method for use in spacecraft components. Background Technology

[0002] Deep holes in workpieces are a very common mechanical structure, often used to achieve mechanical connections between workpieces and other components. Deep holes in workpieces are typically machined using a machine tool, where a drill connected to the machine tool drills the deep hole in the workpiece.

[0003] Because spacecraft components require the machining of deep holes of varying diameters and lengths, current technology typically involves using machine tools to machine a batch of spacecraft components with deep holes of the same diameter, followed by changing to a gun drill to machine other diameter deep holes in the same batch. This method requires repeated batch operations involving clamping the spacecraft components, impacting machining efficiency and affecting machining accuracy. Furthermore, during deep hole machining, the outer edge of the guide sleeve adheres to the surface of the workpiece. The continuous flow of cutting fluid and metal debris causes wear on the guide sleeve. The chemical components in the cutting fluid or the corrosive effects of metal debris can also lead to corrosion or wear of the guide sleeve, necessitating timely replacement to avoid affecting subsequent machining. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a deep hole machining equipment and a method for using spacecraft components.

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

The tool feed mechanism includes a tool holder with multiple tool slots of equal arc on the tool holder. A tool holder is slidably installed in each of the multiple tool slots. A gun drill for deep hole machining is provided on one side of the tool holder.

[0008] A guide adjustment mechanism is located on one side of the tool feed mechanism. The guide adjustment mechanism synchronously switches guide sleeves according to the tool being switched in the tool feed mechanism. The guide adjustment mechanism includes a shaft box with through holes at both ends for the gun drill to pass through. An adjustment plate is located on one side of the shaft box, and multiple guide sleeves are mounted on the adjustment plate. Multiple fixing slots are located on the adjustment plate, and fixing components are installed in the slots on both sides of each fixing slot. Each fixing component includes a locking plate with protruding engaging parts one and two on one side. A spring is installed in the slot, with one end of the spring fixedly connected to the slot and the other end connected to the locking plate. A strip-shaped groove is located on the guide sleeve, and the engaging parts one and two of the locking plate engage with the two ends of the strip-shaped groove on the guide sleeve.

[0009] A guide replacement mechanism is provided above the guide adjustment mechanism. The guide replacement mechanism is used to replace the corroded and worn guide sleeve on the guide adjustment mechanism. The guide replacement mechanism includes an upper shelf and a lower shelf. Both the upper shelf and the lower shelf are mounted on the axle box by a fixing frame. A liftable gripper cylinder is provided on one side of the fixing frame. The gripper cylinder is located above the mixing plate.

[0010] The loading mechanism is located below the guiding and adjusting mechanism and is used to support and fix spacecraft parts.

[0011] Furthermore, a top shaft is fixedly installed on the second engaging part, and a top groove is opened on the dispensing plate. The top groove communicates with the slot, and the top shaft is slidably connected to the top groove.

[0012] Furthermore, a replacement frame is connected to one side of the fixed frame, a back plate is rotatably mounted on the replacement frame, a push cylinder is fixedly mounted on one side of the back plate, the gripper cylinder is connected to the piston rod of the push cylinder, and a rotary cylinder that drives the back plate to rotate is provided on one side of the replacement frame.

[0013] Furthermore, a push plate is fixedly installed on one side of the gripper cylinder. The bottom of the push plate is arc-shaped, and the push plate abuts against the top shaft.

[0014] Furthermore, each of the plurality of fixing grooves corresponds to one of the plurality of guide sleeves, and the guide sleeves engage with the fixing grooves.

[0015] Furthermore, the gun drill is started by a drive motor, which is mounted on the tool holder. The tool holder is rotatably mounted on the mounting base, which is equipped with a rotary motor that drives the tool holder to rotate. The mounting base is slidably mounted on the base, which is fixedly mounted on the machine tool. A hydraulic cylinder that drives the mounting base to move is provided on one side of the machine tool.

[0016] Furthermore, a guide groove is provided in the tool slot, and multiple electric push rods are provided in the tool holder, with the piston rod of the electric push rod fixedly connected to the tool holder.

[0017] Furthermore, the feeding mechanism includes a feeding frame, which is mounted on the machine tool. The feeding frame has two symmetrically arranged fixed claws, which are slidably installed at both ends of a clamping groove. A movable lead screw is rotatably mounted in the clamping groove. The threads at both ends of the movable lead screw are symmetrically arranged along the middle. The two fixed claws are threadedly connected to both ends of the movable lead screw. A movable motor for driving the movable lead screw to rotate is provided on one side of the feeding frame. The feeding frame also has a liftable lifting frame.

[0018] A method for using a deep hole machining equipment for spacecraft components includes the following steps:

[0019] Step 1: Secure the spacecraft parts to the loading rack of the loading mechanism and fix them in place using two fixing claws;

[0020] Step 2: Select a gun drill of the set size, and rotate the motor to drive the tool holder to rotate, so that the gun drill moves to the top and is on the same axis as the through hole of the shaft box;

[0021] Step 3: The gripper cylinder grabs the guide sleeve on the lower shelf. The rotary cylinder drives the gripper cylinder to rotate to the slot of the mixing plate. The first and second engaging parts of the clamping plate engage with the two ends of the strip groove on the guide sleeve. Under the action of the spring, the guide sleeve is fixed.

[0022] Step 4: According to the size of the gun drill, the adjusting motor drives the adjusting plate to rotate, so that the guide sleeve that mates with the gun drill in the fixed groove on the adjusting plate moves to the through hole, so that the guide sleeve and the gun drill are on the same axis.

[0023] Step 5: The gun drill feeds towards one side of the axle box and passes through the guide sleeve inside the axle box to contact the spacecraft component on one side. The drive motor drives the gun drill to rotate, realizing the deep hole drilling operation on the spacecraft component. The liftable lifting frame and the sliding loading frame are used to perform deep hole processing operations on different positions of the spacecraft component.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] This invention incorporates a tool feed mechanism and a guide adjustment mechanism. The tool feed mechanism automatically switches to a matching gun drill based on the dimensions of different deep holes being machined, while the guide adjustment mechanism synchronously switches to a matching guide sleeve based on the switched gun drill. This achieves synchronized adjustment of the gun drill and the guide sleeve, thereby enabling the machining of deep holes of different dimensions for spacecraft components. Furthermore, the invention utilizes a guide replacement mechanism to automatically replace damaged guide sleeves on the guide adjustment mechanism, reducing the risk associated with manual replacement without requiring machine downtime.

[0026] By setting up a tool feed mechanism, gun drills of different sizes can be fixed on the tool feed mechanism at the same time. By switching the tools, the machining of deep holes of different sizes can be realized. This setting can machine deep holes on spacecraft parts in one go without repeated batch operations.

[0027] By setting up a guide adjustment mechanism, a fixing component is set in the fixing groove on the guide adjustment mechanism. The two opening and closing parts one and the locking part two on the fixing component realize the automatic locking and tightening of the guide sleeve, which has high stability. Compared with the conventional bolt connection, this setting does not require manual replacement by stopping the machine. At the same time, the top shaft set on the locking part two cooperates with the push plate on the guide replacement mechanism to release the guide sleeve in the fixing groove while clamping the guide sleeve, thereby completing the subsequent guide sleeve replacement operation and avoiding the damage of the guide sleeve from affecting subsequent processing.

[0037] Reference Figures 1 to 8 The present invention is a deep hole machining equipment for spacecraft parts, including a machine tool 10, on which a tool feed mechanism 20 is provided. The tool feed mechanism 20 is used for deep hole machining and automatic tool switching, so as to realize one-time machining of deep holes of different diameters in spacecraft parts.

[0038] The tool feed mechanism 20 includes a tool holder 21, on which multiple tool slots 22 are formed at equal arcs. A tool holder is slidably installed in each of the multiple tool slots 22. A gun drill 24 for deep hole machining is provided on one side of the tool holder. The gun drill 24 is started by a drive motor 25, which is mounted on the tool holder. A guide groove 26 is formed in the tool slots 22. Multiple electric push rods are provided in the tool holder 21. The piston rod of the electric push rod is fixedly connected to the tool holder. The electric push rod drives the tool holder to move, which in turn drives the gun drill 24 on one side of the tool holder to move. This arrangement is used to avoid interference between gun drills 24 of different lengths and specifications and spacecraft parts and other components when switching tools.

[0039] The tool holder 21 is rotatably mounted on the mounting base 27. The mounting base 27 is equipped with a rotary motor that drives the tool holder 21 to rotate. The mounting base 27 is slidably mounted on the base 28. The base 28 is fixedly mounted on the machine tool 10. A hydraulic cylinder 29 is provided on one side of the machine tool 10 to drive the mounting base 27 to move. The hydraulic cylinder 29 drives the mounting base 27 to slide on the base 28. At this time, the gun drill 24 feeds towards the side of the shaft box 31 and passes through the guide sleeve 34 in the shaft box 31 to contact the spacecraft accessory on one side. The drive motor 25 drives the gun drill 24 to move, realizing the deep hole drilling operation of the spacecraft accessory.

[0040] The guide adjustment mechanism 30 is located on one side of the tool feed mechanism 20. The guide adjustment mechanism 30 synchronously switches the guide sleeve 34 according to the tool switched in the tool feed mechanism 20, which improves the stability of the tool during processing and can automatically replace the damaged guide sleeve 34.

[0041] The guide and adjustment mechanism 30 includes a shaft box 31, which is fixedly installed on the machine tool 10. Both ends of the shaft box 31 are provided with through holes 32 through which the gun drill 24 passes. An opening 39 is provided on one side of the shaft box 31. An adjustment plate 33 is rotatably installed at the opening 39 of the shaft box 31. Multiple guide sleeves 34 are provided on the adjustment plate 33. An adjustment motor that drives the adjustment plate 33 to rotate is provided on the shaft box 31.

[0042] The mixing plate 33 has multiple fixing slots 35, which correspond one-to-one with multiple guide sleeves 34. The guide sleeves 34 and the fixing slots 35 are engaged and matched. Fixing elements 37 are provided in the slots 36 on both sides of the multiple fixing slots 35.

[0043] The fixing component 37 includes a clamping plate 371. The clamping plate 371 has a protruding engaging part 372 and a second engaging part 373 on one side. A spring 374 is installed in the slot 36. When the guide sleeve 34 is fixed, the spring 374 is in a compressed state. One end of the spring 374 is fixedly connected to the slot 36, and the other end is connected to the clamping plate 371. A strip groove 341 is opened on the guide sleeve 34. The engaging part 372 and the second engaging part 373 of the clamping plate 371 engage with both ends of the strip groove 341 on the guide sleeve 34 to fix the guide sleeve 34. A top shaft 375 is fixedly installed on the second engaging part 373. A top groove 38 is opened on the mixing plate 33. The top groove 38 communicates with the slot 36. The top shaft 375 is slidably connected to the top groove 38.

[0044] When the guide sleeve 34 is inserted into the fixing groove 35, the guide sleeve 34 drives the first engagement part 372 on the clamping plate 371 to retract into the groove 36. At this time, the guide sleeve 34 can continue to move forward. When the guide sleeve 34 passes through the first engagement part 372 of the clamping plate 371 and contacts the second engagement part 373, under the action of the spring 374, the two ends of the guide sleeve 34 strip groove 341 are simultaneously engaged by the first engagement part 372 and the second engagement part 373 of the clamping plate 371, so as to realize the automatic fixing of the guide sleeve 34.

[0045] A guide replacement mechanism 40 is located above the guide adjustment mechanism. The guide replacement mechanism 40 is used to replace guide sleeves 34 worn due to corrosion on the guide adjustment mechanism. The guide replacement mechanism 40 includes an upper shelf 41 and a lower shelf 42. The upper shelf 41 is located above the lower shelf 42. Guide sleeves 34 awaiting replacement are placed inside the lower shelf 42, while replaced guide sleeves 34 are placed on the upper shelf 41. Both the upper shelf 41 and the lower shelf 42 are mounted on the axle box 31 via a fixing bracket 43. A replacement bracket 44 is connected to one side of the fixing bracket 43. A back plate 45 is rotatably mounted on the replacement bracket 44, and a push cylinder 4 is fixedly mounted on one side of the back plate 45. 6. The piston rod of the push cylinder 46 is fixedly connected to the gripper cylinder 47. The gripper cylinder 47 is located above the mixing plate 33. A rotary cylinder that drives the back plate 45 to rotate is provided on one side of the replacement rack 44. When the guide sleeve 34 needs to be replaced, the gripper cylinder 47 is used to clamp the guide sleeve 34 to be replaced. The rotary cylinder drives the gripper cylinder 47 to rotate to the upper shelf 41. The damaged guide sleeve 34 is placed on the upper shelf 41. The gripper cylinder 47 grabs the guide sleeve 34 on the lower shelf 42. The rotary cylinder drives the gripper cylinder 47 to rotate to the slot 36 of the mixing plate 33. The guide sleeve 34 is engaged in the slot 36, and the replacement of the guide sleeve 34 is completed.

[0046] A push plate 48 is fixedly installed on one side of the gripper cylinder 47. The bottom of the push plate 48 is arc-shaped. When the gripper cylinder 47 moves downward to grip the guide sleeve 34, the push plate 48 on one side of the gripper cylinder 47 first contacts the top shafts 375 on the two fixing parts 37. Under the action of the push plate 48, the two top shafts 375 slide in opposite directions, thereby causing the fixing parts 37 to retract into the slot 36, realizing the release of the guide sleeve 34. At this time, the guide sleeve 34 in the fixing slot 35 can be easily gripped by the gripper cylinder 47.

[0047] It should be further explained that the tool feed mechanism 20 automatically switches the matching gun drill 24 according to the size of different deep holes to be processed. At the same time, the guide adjustment mechanism 30 synchronously switches the guide sleeve 34 that matches the gun drill 24 according to the switched gun drill 24, so as to realize the synchronous adjustment of the gun drill 24 and the guide sleeve 34, thereby realizing the processing of deep holes of different sizes for spacecraft parts. Meanwhile, the guide replacement mechanism 40 automatically replaces the damaged guide sleeve 34 on the guide adjustment mechanism 30, which reduces the risk of manual replacement without stopping the machine.

[0048] The feeding mechanism 50 is located below the guiding and adjusting mechanism 30 and is used for the support and fixation of spacecraft parts.

[0049] The feeding mechanism 50 includes a feeding frame 51, which is mounted on the machine tool 10. The feeding frame 51 has two symmetrically arranged fixed claws 52, which are slidably mounted at both ends of a clamping groove 53. A movable lead screw 54 is rotatably mounted within the clamping groove 53. The threads at both ends of the movable lead screw 54 are symmetrically arranged along its center. The two fixed claws 52 are threadedly connected to both ends of the movable lead screw 54. A movable motor for driving the movable lead screw 54 is located on one side of the feeding frame 51. The feeding frame 51 also has a liftable lifting frame 55. The machine tool 10 is equipped with a drive cylinder that moves the lifting frame 55. The loading frame 51 is slidably mounted on the machine tool 10. The movement of the loading frame 51 can be driven by a motor installed inside the machine tool 10. When fixing spacecraft parts, the moving motor drives the moving screw 54 to rotate. The moving screw 54 drives the two fixing claws 52 to move synchronously, fixing the spacecraft parts on the loading frame 51, which facilitates subsequent deep hole machining operations. The lifting frame 55 and the sliding loading frame 51 are used to realize deep hole machining operations at different positions of spacecraft parts.

[0050] Working principle:

[0051] The spacecraft parts are fixed on the loading rack 51. A gun drill 24 of matching size is selected according to the size of the hole to be drilled. The tool holder 21 is rotated by rotating the motor, so that the gun drill 24 moves to the top and is on the same axis as the through hole 32 of the shaft box 31. At the same time, according to the size of the gun drill 24, the adjusting motor drives the adjusting plate 33 to rotate, so that the guide sleeve 34 that mates with the gun drill 24 in the fixing groove 35 on the adjusting plate 33 moves to the through hole 32, so that the guide sleeve 34 and the gun drill 24 are on the same axis.

[0052] The hydraulic cylinder 29 drives the mounting base 27 to slide on the base 28. At this time, the gun drill 24 feeds towards the side of the shaft box 31 and passes through the guide sleeve 34 inside the shaft box 31 to contact the spacecraft parts on one side. The drive motor 25 drives the gun drill 24 to rotate, realizing the deep hole drilling operation of the spacecraft parts.

[0053] When the guide sleeve 34 is damaged and needs to be replaced, the guide sleeve 34 to be replaced is clamped by the gripper cylinder 47. The push plate 48 on one side of the gripper cylinder 47 first contacts the top shaft 375 on the two fixing parts 37. Under the action of the push plate 48, the two top shafts 375 slide in opposite directions, thereby causing the fixing parts 37 to retract into the slot 36, realizing the release of the guide sleeve 34. The rotary cylinder drives the gripper cylinder 47 to rotate to the upper shelf 41, and the damaged guide sleeve 34 is placed on the upper shelf 41. The gripper cylinder 47 grabs the guide sleeve 34 on the lower shelf 42. The rotary cylinder drives the gripper cylinder 47 to rotate to the slot 36 of the mixing plate 33. The first engagement part 372 and the second engagement part 373 of the clamping plate 371 engage with the two ends of the strip groove 341 on the guide sleeve 34. Under the action of the spring 374, the guide sleeve 34 is automatically fixed.

[0054] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
