These connecting shafts usually need to withstand high-strength and high-precision mechanical loads, and need to have excellent properties such as lightweight, corrosion resistance, and fatigue resistance. Aviation special-shaped connecting shafts are specially designed shafts used to connect parts with complex geometric shapes in aviation systems. In the process of connecting aviation special-shaped parts through connecting shafts, in order to facilitate the improvement of the characteristics of the connecting shafts, some aviation special-shaped connecting shafts need to have annular grooves on their circumferential walls.

[0035] S4: After the annular groove is opened on the connecting shaft of the aviation special-shaped part and the annular groove is polished, the second drive motor is started again. The second drive motor drives the lead screw to rotate in the opposite direction, thereby driving the groove milling cutter, the polishing block and the coating sponge to move in the opposite direction. When the coating sponge contacts the connecting shaft of the aviation special-shaped part, the coating sponge applies protective oil to the surface of the connecting shaft of the aviation special-shaped part and the side wall of the annular groove to prevent the connecting shaft of the aviation special-shaped part from contacting with water vapor in the air during storage and causing oxidation.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. In the present invention, a slot milling cutter is used to perform slotting on the connecting shaft of the aviation special-shaped part. When the slot milling cutter rotates downward on the annular groove on the connecting shaft of the aviation special-shaped part and contacts with a grinding block, the grinding block contacts with the side wall of the annular groove and generates friction, thereby achieving the grinding of the annular groove opened on the connecting shaft of the aviation special-shaped part by the grinding block.

[0038] 2. In the present invention, water in the water tank is transported to the nozzle through the water pipe by a water pump, and is sprayed on the annular groove on the connecting shaft of the aviation special-shaped part by the nozzle. The polished part of the annular groove on the connecting shaft of the aviation special-shaped part is flushed by the water flow, which can not only wash away the grinding in the annular groove on the connecting shaft of the aviation special-shaped part, but also reduce the temperature generated by the friction between the connecting shaft of the aviation special-shaped part and the polishing block. At the same time, the water mist sprayed by the nozzle can prevent the grinding generated during the polishing of the annular groove of the connecting shaft of the aviation special-shaped part from floating into the air, and the sprayed water flows downward through the bottom of the connecting shaft of the aviation special-shaped part to the arc plate, and flows downward through the bottom of the arc plate to the separation box, and the water flows through the filter plate, the filter plate blocks the particulate matter in the water flow, and the water flows downward through the filter holes on the filter plate to the bottom of the separation box, and flows downward through the reflux pipe to the water tank for collection and reuse.

[0039] 3. In the present invention, protective oil is applied to the surface of the aviation special-shaped part connecting shaft and the side wall of the annular groove by using a smearing sponge, wherein the lower end of the smearing sponge protrudes downward and cooperates with the annular groove, so that the smearing sponge can apply protective oil to the side wall of the annular groove on the aviation special-shaped part connecting shaft, thereby preventing the aviation special-shaped part connecting shaft from oxidation during storage, thereby ensuring the storage quality of the aviation special-shaped part connecting shaft.

[0040] 4. In the present invention, the collected particles are melted by a burner. When the metal particles in the furnace are melted, the molten metal flows into the cooling box through the liquid outlet of the furnace, so that the molten metal is cooled and becomes block-shaped, thereby facilitating the recovery and transportation of the debris generated when grooving the connecting shaft of the aviation special-shaped parts.

[0052] Reference Figures 1 to 10 .

[0053] Embodiment 1 further describes a device and method for machining an annular groove of a connecting shaft of an aviation special-shaped part proposed by the present invention.

[0054] A device for processing annular grooves of connecting shafts of aviation special-shaped parts comprises a base 1, the upper surface of which is slidably connected with a clamping plate 2, and a support plate 3, which is symmetrically arranged on the base 1 and vertically fixedly connected to the side wall of the base 1.

The moving mechanism is used to drive the slot milling cutter 4 and the grinding block 5 to move back and forth, wherein the slot milling cutter 4 and the grinding block 5 are detachably fixedly connected to the moving mechanism by screws in the prior art. When the slot milling cutter 4 and the grinding block 5 need to be replaced, the screws are rotated and taken out, thereby facilitating the disassembly and replacement of the slot milling cutter 4 and the grinding block 5, wherein the width value of the grinding block 5 is consistent with the width value of the annular groove opened by the slot milling cutter 4, thereby facilitating the grinding block 5 to grind the annular groove opened by the slot milling cutter 4.

[0056] The flushing mechanism includes a water tank 6, which is fixedly connected to the lower surface of the base 1. A water pump 7 is fixedly connected to the bottom of the water tank 6.

The flushing mechanism is used to clean the contact part between the grinding block 5 and the connecting shaft of the aviation special-shaped part, that is, the ring opened by the slot milling cutter 4 on the connecting shaft of the aviation special-shaped part. Flushing the contact area between the side wall of the annular groove and the grinding block 5 can not only increase the humidity on the connecting shaft of the aviation special-shaped part, but also prevent the grinding chips from flying around during the process of the grinding block 5 grinding the side wall of the annular groove on the connecting shaft of the aviation special-shaped part, and also wash away the remaining grinding chips on the connecting shaft of the aviation special-shaped part. At the same time, it can also take away the heat generated by the friction between the grinding block 5 and the connecting shaft of the aviation special-shaped part, reduce the temperature of the connecting shaft of the aviation special-shaped part, and avoid deformation of the connecting shaft of the aviation special-shaped part due to excessive temperature during grinding.

[0057] The arc plate 10 is fixedly connected to the side wall of the support plate 3 in an inclined manner, and a separation box 11 is provided at the lower end of the arc plate 10, and the separation box 11 is fixedly connected to the side wall of the support plate 3. A return pipe 12 is fixedly connected to the side wall of the separation box 11, and the lower end of the return pipe 12 is connected to the water tank 6. The arc plate 10 is used to collect the water sprayed from the flushing mechanism and the debris generated by the slot milling cutter 4 when the slot is stuck, which is not only convenient for recycling the debris generated when the connecting shaft of the aviation special-shaped part is slotted, but also convenient for recycling the flushing water, thereby reducing the waste of resources.

[0058] The coating mechanism is arranged on the moving mechanism and is used to coat the connecting shaft of the aviation special-shaped part behind the slot with protective oil to prevent the connecting shaft of the aviation special-shaped part from producing oxidation reaction with water vapor in the air due to long storage time.

[0059] The upper surface of the base 1 is fixedly connected with symmetrically arranged electric telescopic rods 13 , and the movable ends of the electric telescopic rods 13 are fixedly connected to the side walls of the clamping plate 2 .

A slide groove is provided on the sliding block 18, and the sliding block 18 is sleeved on the limit plate 19 through the slide groove. Due to the restriction of the limit plate 19 on the sliding block 18, the sliding block 18 is prevented from rotating with the rotation of the lead screw 17, thereby causing the sliding block 18 to be driven to move horizontally during the rotation of the lead screw 17, thereby facilitating the sliding block 18 to slide on the limit plate 19.

[0063] The connecting plate 20 is vertically fixedly connected to the sliding block 18, and the slot milling cutter 4, the grinding block 5 and the nozzle 9 are all arranged on the connecting plate 20. The upper and lower sides of the connecting plate 20 are provided with screws 17, so that the upper and lower screws 17 can drive the upper and lower ends of the connecting plate 20 to move horizontally to one side at the same time during the rotation process, thereby driving the slot milling cutter 4, the grinding block 5 and the nozzle 9 to move horizontally to one side, so that the slot milling cutter 4 can open an annular groove on the connecting shaft of the aviation special-shaped part.

[0068] The liquid storage box 26 is fixedly connected to the side wall of the support plate 3. The lower end of the smear sponge 25 is located in the liquid storage box 26. The liquid storage box 26 is used to load the protective oil. Since the lower end of the smear sponge 25 is in contact with the bottom of the liquid storage box 26, it is convenient for the smear sponge 25 to absorb the protective oil in the liquid storage box 26.

[0069] The liquid storage tank 27 is fixedly connected to the side wall of the support plate 3. A drain pipe 28 is fixedly connected to the side wall of the liquid storage tank 27.

A liquid inlet is provided on the side wall of the liquid storage tank 27. A piston is threadedly connected to the liquid inlet to facilitate injecting the protective oil into the liquid storage tank 27 through the liquid inlet. The drain pipe 28 is located at the bottom of the liquid storage tank 27. The drain pipe 28 is used to discharge the protective oil in the liquid storage tank 27 into the liquid storage box 26.

[0070] The first blocking block 29 is located in the liquid storage tank 27, and the end of the first blocking block 29 is inserted into the port of the discharge pipe 28. The first blocking block 29 is fixedly connected to a connecting rod 30, and the connecting rod 30 is elastically connected to the inner wall of the liquid storage tank 27.

[0072] A sliding rod 32 is slidably connected to the inner wall of the liquid storage tank 27, the upper end of the connecting rod 30 is fixedly connected to the sliding rod 32, a first spring 33 is fixedly connected to the side wall of the sliding rod 32, one end of the first spring 33 is fixedly connected to the inner wall of the liquid storage tank 27, a rectangular slide groove 45 is opened on the side wall of the liquid storage tank 27, the end of the sliding rod 32 is slidably connected in the rectangular slide groove 45, so that the sliding rod 32 is slidably connected to the side wall of the liquid storage tank 27.

[0073] A push rod 34 is fixedly connected to the side wall of the sliding rod 32, and one end of the push rod 34 passes through the side wall of the liquid reservoir 27 and contacts the moving block 23. When the moving block 23 moves to the top of the liquid reservoir box 26, the moving block 23 contacts the push rod 34 and pushes the push rod 34 toward the inside of the liquid reservoir box 27 through the movement of the moving block 23, so that the push rod 34 pushes the sliding rod 32 to one side and drives the connecting rod 30 and the first blocking block 29 to move away from the drain pipe 28, so that the port of the drain pipe 28 is open, thereby facilitating the protective oil in the liquid reservoir tank 27 to flow into the liquid reservoir box 26 through the drain pipe 28.

[0074] The upper side of the drain pipe 28 is provided with a moving rod 35, the upper end of the second blocking block 31 is fixedly connected to the lower surface of the moving rod 35, and the upper surface of the moving rod 35 is fixedly connected to a push plate 36, which is located on the lower side of the moving plate 24. Due to the pushing of the push rod 34 by the moving block 23, the first blocking block 29 is separated from the port of the drain pipe 28, so that the protective oil in the liquid storage tank 27 flows into the liquid storage box 26 through the drain pipe 28. When the smear sponge 25 absorbs the protective oil to a saturated state, at this time, the weight of the smear sponge 25 increases, and the moving plate 24 slides downward due to the weight of the smear sponge 25. When the moving plate 24 contacts the push plate 36, the moving plate 24 pushes the push plate 36 downward, driving the second blocking block 31 to move downward, so that the second blocking block 31 closes the liquid outlet of the drain pipe 28, thereby preventing the protective oil in the liquid storage tank 27 from being continuously discharged from the drain pipe 28 and overflowing from the liquid storage box 26.

[0075] A strip-shaped slide groove 44 is provided on the side wall of the support plate 3, and a second spring 38 is fixedly connected to the bottom of the strip-shaped slide groove 44, and a sliding plate 39 is fixedly connected to the upper end of the second spring 38.

Through the elastic force of the second spring 38, the second spring 38 pushes the sliding plate 39 upward, drives the push plate 36 and the moving rod 35 to move upward, and drives the second blocking block 31 to move upward, so that the port of the discharge pipe 28 located directly above the liquid storage box 26 is in an open state.

[0076] The lower end of the filter plate 21 is fixedly connected to the furnace 40, and a cooling box 41 is provided at the lower end of the solution discharge outlet of the furnace 40. A pipe 42 is provided on one side of the cooling box 41, and a fan 43 is fixedly connected inside the pipe 42. The pipe 42 is fixedly connected to the side wall of the support plate 3, and the air outlet of the pipe 42 is located on one side of the fixed cylinder 15, and the air outlet of the pipe 42 is located on the lower side of the smear sponge 25.

[0077] The cooling box 41 is located directly below the liquid outlet of the furnace 40, so as to facilitate loading the molten metal liquid in the furnace 40, and the air inlet of the pipe 42 is located directly above the cooling box 41, and the materials of the pipe 42, the cooling box 41 and the fan 43 are all high-temperature resistant materials, wherein the wires on the fan 43 are electrically connected to the power supply in the prior art, and the fan 43 is used to blow the heat dissipated upward by the metal solution in the cooling box 41 toward the connecting shaft of the aviation special-shaped part through the pipe 42, thereby facilitating the drying of the connecting shaft of the aviation special-shaped part after cleaning.

[0078] Working principle: Place the connecting shaft of the aviation special-shaped part that needs to be annularly grooved between the two fixed cylinders 15, start the electric telescopic rod 13, and the electric telescopic rod 13 pushes the two fixed cylinders 15 toward each other, so that the two fixed cylinders 15 clamp and fix the ends of the connecting shaft of the aviation special-shaped part, thereby achieving the fixation of the connecting shaft of the aviation special-shaped part.

[0079] The first drive motor 14 and the second drive motor 16 are started, and the output shaft of the first drive motor 14 drives the fixed cylinder 15 to rotate, thereby driving the connecting shaft of the aviation special-shaped part clamped by the fixed cylinder 15 to rotate. During the rotation of the second drive motor 16, the output shaft of the second drive motor 16 drives the lead screw 17 to rotate. Since the sliding block 18 and the moving block 23 are slidably connected to the limit plate 19, the sliding block 18 and the moving block 23 are prevented from rotating with the rotation of the lead screw 17. At the same time, the lead screw 17 is restricted by the nut and the thread on the lead screw 17, so that during the rotation of the lead screw 17, the sliding block 18 and the moving block 23 are driven to move horizontally to one side, and the sliding block 18 drives the connecting plate 20, the slot milling cutter 4, the grinding block 5 and the nozzle 9 to The movable block 23 drives the movable plate 24 and the smear sponge 25 to move in the direction away from the connecting shaft of the aviation special-shaped part. When the slot milling cutter 4 contacts the circumferential wall of the connecting shaft of the aviation special-shaped part, the first drive motor 14 drives the connecting shaft of the aviation special-shaped part to rotate, so that the connecting shaft of the aviation special-shaped part is opposite to the blade of the slot milling cutter 4 during the rotation, so that the slot milling cutter 4 slots the connecting shaft of the aviation special-shaped part. When the slot milling cutter 4 rotates downward on the annular groove on the connecting shaft of the aviation special-shaped part and contacts with the grinding block 5, the grinding block 5 contacts the side wall of the annular groove and generates friction, thereby realizing that the grinding block 5 grinds the annular groove opened on the connecting shaft of the aviation special-shaped part.

[0080] During the process of the slot milling cutter 4 slotting the connecting shaft of the aviation special-shaped part, the second drive motor 16 slowly pushes the slot milling cutter 4 and the grinding block 5 toward the direction of the connecting shaft of the aviation special-shaped part through the sliding block 18 and the connecting plate 20, thereby increasing the depth of the annular groove opened by the slot milling cutter 4 on the connecting shaft of the aviation special-shaped part. At the same time, the moving block 23 is also pushed toward the direction of the liquid storage box 26. When the moving block 23 contacts the push rod 34, as the position of the moving block 23 moves, the moving block 23 pushes the push rod 34 into the liquid storage tank 27, and drives the sliding rod 32, the connecting rod 30 and the first blocking block 29 to push away from the drain pipe 28. When the end of the push rod 34 is flush with the side wall of the support plate 3, the first blocking block 29 is located on one side of the drain pipe 28, and the drain pipe 28 is open, and the protective oil in the liquid storage tank 27 flows into the liquid storage box 26 through the drain pipe 28. When the moving plate 24 contacts the push plate 36, the moving plate 24 presses the push plate 36 downward, driving the moving rod 35 and the second blocking block 31 to move downward. When the lower end surface of the second blocking block 31 contacts the bottom of the drain pipe 28, the drain pipe 28 is in a closed state, thereby preventing the protective oil in the reservoir 27 from continuing to flow out through the drain pipe 28, thereby preventing the protective oil accumulated in the reservoir box 26 from overflowing from the reservoir box 26 due to excessive protective oil accumulation, thereby avoiding waste of protective oil. At the same time, the second spring 38 is in a contracted state, while the third spring 37 is in a stretched state.

[0081] Turn on the water pump 7, and the water pump 7 transports the water in the water tank 6 to the nozzle 9 through the water pipe 8, and sprays it on the annular groove on the connecting shaft of the aviation special-shaped part through the nozzle 9. The grinding part of the annular groove on the connecting shaft of the aviation special-shaped part is flushed by the water flow, which can not only wash away the grinding in the annular groove on the connecting shaft of the aviation special-shaped part, but also reduce the temperature generated by the friction between the connecting shaft of the aviation special-shaped part and the grinding block 5. At the same time, the water mist sprayed by the nozzle 9 can prevent the grinding generated during the grinding of the annular groove of the connecting shaft of the aviation special-shaped part from floating into the air, and the sprayed water flows downward through the bottom of the connecting shaft of the aviation special-shaped part to the arc plate 10, and flows downward through the bottom of the arc plate 10 to the separation box 11, and the water flows through the filter plate 21, the filter plate 21 blocks the particulate matter in the water flow, and the water flows downward through the filter holes on the filter plate 21 to the bottom of the separation box 11, and flows downward through the reflux pipe 12 to the water tank 6 for collection and reuse.

[0082] The particles blocked on the filter plate 21 slide down the inclined surface of the filter plate 21 into the furnace 40, and the burner in the furnace 40 is turned on to melt the collected particles. When the metal particles in the furnace 40 are melted, the molten metal flows into the cooling box 41 through the liquid outlet of the furnace 40, so that the molten metal is cooled and formed into blocks, thereby facilitating the recovery and transportation of the debris generated when the connecting shaft of the aviation special-shaped parts is grooved.

[0083] When the annular groove on the connecting shaft of the aviation special-shaped part is slotted and polished, the water pump 7 is turned off, and at the same time, the output shaft of the second drive motor 16 drives the lead screw 17 to rotate in the opposite direction, and the lead screw 17 drives the sliding block 18 and the moving block 23 to move in the opposite direction through the thread, so that the sliding block 18 drives the groove milling cutter 4 and the grinding block 5 to move away from the connecting shaft of the aviation special-shaped part, and the moving block 23 drives the smear sponge 25 to move toward the direction of the connecting shaft of the aviation special-shaped part. At this time, the push rod 34 is separated from the pushing of the moving block 23, and at the same time, through the elastic force of the first spring 33, the first spring 33 pushes the sliding rod 32 to one side. The connecting rod 30 and the first blocking block 29 are driven to move toward the port of the discharge pipe 28. When the moving block 23 is completely separated from the push rod 34, the first blocking block 29 is separated from the push rod 34, and the first blocking block 29 is completely inserted into the port of the discharge pipe 28, thereby closing the port of the discharge pipe 28. When the moving plate 24 is separated from the push plate 36, the push plate 36 is separated from the downward extrusion force of the moving plate 24. At this time, through the elastic force of the second spring 38, the second spring 38 pushes the sliding plate 39 upward, driving the push plate 36, the moving rod 35 and the second blocking block 31 to move upward, thereby restoring the position of the second blocking block 31.

[0084] Start the fan 43, which blows the air from the air inlet of the pipe 42 to the air outlet of the pipe 42. When the wind passes through the cooling box 41, it takes away the heat dissipated from the cooling box 41, thereby increasing the cooling rate of the molten metal in the cooling box 41, so that the cooled molten metal is in block shape, which is convenient for transporting the formed metal powder and brings convenience to the staff. At the same time, the hot wind is blown onto the connecting shaft of the aviation special-shaped part through the air outlet of the pipe 42, thereby increasing the drying rate of the residual moisture on the surface of the connecting shaft of the aviation special-shaped part.

[0085] When the coating sponge 25 contacts the aviation special-shaped part connecting shaft, the coating sponge 25 coats the protective oil on the surface of the aviation special-shaped part connecting shaft and the side wall of the annular groove, wherein the lower end of the coating sponge 25 protrudes downward and cooperates with the annular groove, so that the coating sponge 25 coats the protective oil on the side wall of the annular groove on the aviation special-shaped part connecting shaft, thereby preventing the aviation special-shaped part connecting shaft from oxidation during storage, thereby ensuring the storage quality of the aviation special-shaped part connecting shaft. When the protective oil in the coating sponge 25 decreases, the weight of the coating sponge 25 will also decrease, and through the pulling force of the third spring 37, the movable plate 24 will be pulled upward, and the coating sponge 25 will be driven to move upward, thereby facilitating the coating sponge 25 and the movable plate 24 to restore their positions.

The aviation special-shaped part connecting shaft contacts the slot milling cutter 4 during the rotation process, so that the slot milling cutter 4 performs slotting processing on the aviation special-shaped part connecting shaft, and the grinding block 5 grinds the annular groove opened by the slot milling cutter, thereby realizing the annular groove processing of the aviation special-shaped part connecting shaft;

[0092] S4: After the annular groove is opened on the aviation special-shaped connecting shaft and the annular groove is polished, the second drive motor 16 is started again.

When the coating sponge 25 contacts the aviation special-shaped connecting shaft, the coating sponge 25 applies protective oil to the surface of the aviation special-shaped connecting shaft and the side wall of the annular groove to prevent the aviation special-shaped connecting shaft from contacting with water vapor in the air during storage and causing oxidation.
