A cleaning device for deep processing of titanium alloy

Abstract

The present invention discloses a cleaning device for deep processing of titanium alloys, belonging to the field of jet cleaning devices, including a processing head body and a bottom shield. A cavity is provided inside the bottom shield, and a plurality of waste collection grooves arranged in an annular array are provided on the inner side wall of the bottom shield, and one end of the waste collection groove is communicated with the cavity of the bottom shield. Through the cooperative setting of the driving rotary cover and the arc-shaped docking head, when the driving rotary cover rotates, it can drive the jet gun rod and the splash-proof nozzle installed on the jet gun rod to rotate through the arc-shaped docking head. The rotation of the jet gun rod can facilitate the rapid blowing off of the debris in the gaps on the surface of the titanium alloy, improving the processing smoothness of the processing head body. The splash-proof nozzle can form an air resistance band above the jet gun rod to blow the titanium alloy powder and debris into the bottom shield, which can not only prevent the titanium alloy powder from drifting and the debris from splashing, but also quickly suck away the titanium alloy powder and debris through the bottom shield.

Description

Technical Field

[0001] The present invention relates to the technical field of jet cleaning devices, and particularly to a cleaning device for deep processing of titanium alloys. Background Art

[0002] In the existing processing of titanium alloys, an air gun is usually used to remove titanium alloy chips in the gaps, which can not only improve the smoothness of titanium alloy processing, but also prevent titanium alloy chips from obstructing the tool body or drill bit, resulting in the fracture of the tool body or drill bit.

[0003] However, when the existing air gun is used in combination with the tool body or drill bit to process titanium alloys, since the position of the air gun is fixed, it is unable to effectively blow away the chips in the gaps of the titanium alloy workpieces, thus affecting the smoothness of titanium alloy processing. At the same time, when blowing away the titanium alloy chips by the air gun, it is easy to cause the powdery titanium alloy chips to disperse and the block or sheet-like titanium alloy chips to fly randomly, which is not conducive to the staff to clean the titanium alloy powder and chips in the processing equipment later. Summary of the Invention

[0007] Preferably, the telescopic assembly includes a robotic arm connector that is sleeved on the top convex edge of the processing head body, a compression spring is fixed between the bottom of the robotic arm connector and the upper surface of the processing head body, and the lower surface of the robotic arm connector is rotatably connected to the base surface of the driving rotating cover.

[0008] Preferably, the air supply assembly comprises a rotating shaft tube sleeved on the middle part of the air jet gun rod, a gas communication groove is provided on the side of the rotating shaft tube, and an annular support frame is provided at both ends of the rotating shaft tube.

[0009] Preferably, six air inlet holes are opened on the top of the annular support frame, and the bottoms of the six air inlet holes are connected through a rotating shaft tube, and an air pump is plugged into the top of the six air inlet holes.

[0010] Preferably, the surrounding assembly comprises a bent pipe frame fixed to the inner side wall of the annular support frame, and a connecting socket is sleeved on the side of the bent pipe frame.

[0011] Preferably, the support assembly includes a leg plate plugged into one end of the connecting seat, and one end of the leg plate is tightly fitted to the outer side of the processing head body.

[0012] Preferably, an adjusting bolt is threadedly connected to the inner wall of the leg plate, and one end of the adjusting bolt is connected to the inner wall of the countersunk hole of the connecting seat through a bearing.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention drives the rotating cover and the arc-shaped joint to cooperate with each other. When the rotating cover is driven to rotate, the arc-shaped joint can drive the jet gun rod and the splash-proof nozzle installed on the jet gun rod to rotate. The rotation of the jet gun rod can quickly blow away the debris in the machining gap on the titanium alloy surface, thereby improving the smoothness of the machining of the machining head body. The splash-proof nozzle can form a multi-layer stacked fan-shaped wind resistance belt above the jet gun rod, which can effectively isolate the titanium alloy powder from drifting and the debris from splashing, and can quickly extract the titanium alloy powder and debris through the bottom shield, thereby reducing the later cleaning work of the staff.

[0016] 2. The present invention cooperates with the auxiliary driving rod and the toggle plate. When the processing head body moves upward to squeeze and drive the rotating cover, the pressed top end of the rotating cover moves upward, and the jet gun rod is squeezed by the arc-shaped butt joint to rotate as a whole, so that the chip cleaning air cavity of the jet gun rod blows air toward the drill bit to clean the chips. The rotation of the jet gun rod will cause the auxiliary driving rod to move downward to squeeze the toggle plate to cause the splash-proof nozzle to expand, forming a multi-layer stacked arc-shaped air wall to prevent aluminum alloy chips from splashing.

[0017] 3. The present invention sets a bottom shield, which is an exhaust device. The gas blown out by the jet gun rod and the splash-proof nozzle can form a backflow, so that the aluminum alloy powder and debris blown out by the jet gun rod and the splash-proof nozzle can be quickly extracted, thereby preventing the aluminum alloy powder and debris from scattering and splashing, and reducing the difficulty of later cleaning by the staff.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, terms such as "installation", "equipped with", "sheathed / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example, refer to Figures 1 to 9 , a cleaning device for deep processing of titanium alloy, including a processing head body 1 and a bottom shield 2. A cavity is provided inside the bottom shield 2, and a plurality of waste collection grooves 3 arranged in a circular array are provided on the inner side wall of the bottom shield 2. One end of the waste collection groove 3 is communicated with the cavity of the bottom shield 2. The top end of the processing head body 1 is connected to a robotic arm through a telescopic component. Further, the telescopic component includes a robotic arm connector 18 sleeved on the convex edge at the top end of the processing head body 1. A compression spring 19 is fixed between the bottom of the robotic arm connector 18 and the upper surface of the processing head body 1. The lower surface of the robotic arm connector 18 is rotatably connected to the surface of the base of the driving rotary cover 4.

[0032] The advantage of the above further arrangement is that: a suction device is connected to the bottom channel of the bottom shield 2. Through the suction device, the aluminum alloy powder and debris blown out by the jet gun rod 6 and the splash-proof nozzle 14 can be quickly sucked into the waste collection bag. After the bottom of the processing head body 1 contacts the aluminum alloy workpiece, it moves upward under the action of the return spring 29, thereby squeezing the driving rotary cover 4. The top end of the driving rotary cover 4 moves upward under pressure. The jet gun rod 6 is rotated by squeezing through the arc-shaped docking head 5, so that the bottom of the jet gun rod 6 moves towards the processing end of the processing head body 1.

[0033] The top side of the housing of the processing head body 1 is closely attached to the driving rotary cover 4. Six arc-shaped docking heads 5 are provided on the top side of the driving rotary cover 4. The top ends of the six arc-shaped docking heads 5 are connected to a jet gun rod 6 through a docking groove. The jet gun rod 6 is arranged in an L shape. An air supply component is sleeved in the middle of the jet gun rod 6. Further, the air supply component includes a rotating shaft tube 20 sleeved in the middle of the jet gun rod 6. A gas communication groove 21 is provided on the side of the rotating shaft tube 20. Ring-shaped support frames 22 are provided at both ends of the rotating shaft tube 20. Six air inlet holes 23 are provided at the top of the ring-shaped support frame 22. The bottoms of the six air inlet holes 23 are communicated through the rotating shaft tube 20. An air pump 26 is inserted into the tops of the six air inlet holes 23.

[0034] The further advantages of adopting the above are as follows: The driving rotary cover 4 is driven to rotate by a motor, and the body of the driving rotary cover 4 is a flexible plate, which can be deformed under the extrusion of the processing head body 1. The top end moves upward to extrude the air jet gun rod 6. Since the arc-shaped docking head 5 is connected to the air jet gun rod 6 in a card slot manner, the card slot between the arc-shaped docking head 5 and the air jet gun rod 6 can still be connected when the driving rotary cover 4 deforms. Therefore, when the driving rotary cover 4 rotates, it can drive the air jet gun rod 6 to rotate accordingly, and the air jet gun rod 6 itself will rotate around the rotating shaft tube 20. When the air jet gun rod 6 rotates, it will communicate with the gas communication groove 21 on the side of the rotating shaft tube 20, so that the gas inhaled by the air pump 26 from the intake hole 23 is ejected from the chip cleaning gas cavity 7.

[0035] An annular component is provided inside the air supply component. Further, the annular component includes a bent pipe holder 24 fixed to the inner side wall of the annular support frame 22, and a connecting socket 25 is sleeved on the side of the bent pipe holder 24.

[0036] The further advantages of adopting the above are as follows: The bent pipe holder 24 can ensure the rotation of the annular support frame 22. Since the rotation of the driving rotary cover 4 will drive the air jet gun rod 6 on the annular support frame 22 to rotate accordingly, the annular support frame 22 will also rotate.

[0037] One end of the annular component is connected to the processing head body 1 through a support component. Further, the support component includes a leg plate 27 inserted into one end of the connecting socket 25. One end of the leg plate 27 is closely attached to the outer side of the processing head body 1. An adjusting bolt 28 is threadedly connected to the inner wall of the leg plate 27, and one end of the adjusting bolt 28 is connected to the inner wall of the counterbore of the connecting socket 25 through a bearing.

[0038] The further advantages of adopting the above are as follows: Rotating the adjusting bolt 28 can change the cross length between the connecting socket 25 and the leg plate 27. Therefore, the annular support frame 22 can be connected to the processing head body 1 through the leg plate 27 and the connecting socket 25.

[0039] A chip cleaning gas cavity 7 and an assembly cavity 8 are provided inside the air jet gun rod 6. A secondary driving rod 9 is connected to the inner bottom wall of the assembly cavity 8 through a reset component. Further, the reset component includes a reset spring 29 fixed between the inner bottom wall of the assembly cavity 8 and the bottom end of the secondary driving rod 9, and the assembly cavity 8 is adapted to the secondary driving rod 9.

[0040] The further advantages of adopting the above are as follows: The reset spring 29 can drive the secondary driving rod 9 to reset, losing the supporting effect on the splash-proof nozzle 14, so that the splash-proof nozzle 14 resets under its own gravity.

[0041] The top arc surface of the auxiliary drive rod 9 is closely attached to a toggle disk 10. Three finger pressure plates 11 are fixed to the side surface of the auxiliary drive rod 9. The inner wall of a counterbore opened on the outer side of the air jet gun rod 6 is fixed with an air guide pipe 12. A gas distribution channel 13 is opened in the middle of the gun rod of the air jet gun rod 6. And the chip cleaning air cavity 7 is communicated with the air guide pipe 12 through the gas distribution channel 13. An anti-splash nozzle 14 is sleeved on the outer side of the air guide pipe 12. Displacement grooves 15 are opened on the outer sides of the three anti-splash nozzles 14. A docking hole 16 is opened on the side surface of the air guide pipe 12. One end of the anti-splash nozzle 14 is provided with an anti-splash air jet cavity 17, and the anti-splash air jet cavity 17 is arranged in a fan shape.

[0042] After the air jet gun rod 6 rotates, it will cause the toggle disk 10 to squeeze the auxiliary drive rod 9. The auxiliary drive rod 9 is pressed and moves downward, driving the anti-splash nozzle 14 to rotate through the finger pressure plates 11, so that the anti-splash nozzles 14 unfold to form an arc-shaped air wall to prevent titanium alloy chips from splashing. The anti-splash air jet cavity 17 is arranged in a fan shape, enabling the gas ejected by the six anti-splash nozzles 14 to enclose a complete arc surface to block the splashing of titanium alloy chips (the wind belts are stacked in multiple layers with a large thickness, and the chips cannot effectively pass through the wind belts. The anti-splash nozzles 14 are arranged at the top of the processing head body 1. When the chips splash and contact the wind belts, they will be blown by the wind belts and spread to the edge. During the spreading process, they will be sucked away by the waste collection groove 3 opened on the inner wall of the bottom shield 2. The suction of the waste collection groove 3 and the blowing force of the anti-splash nozzles 14 can form a wind conveyor belt to timely draw away the chips). The included angles of the displacement grooves 15 opened on the anti-splash nozzles 14 increase successively from top to bottom, so that the gas ejected after the three anti-splash nozzles 14 unfold forms a multi-layer stacked arc surface, improving the effect of blocking titanium alloy chips.

[0043] When the present invention is in use, the robotic arm drives the robotic arm connector 18 to move downward, and the processing head body 1 follows and moves downward. After contacting the titanium alloy workpiece, the processing head body 1 is pressed and contracts close to the robotic arm connector 18. After the processing head body 1 approaches the robotic arm connector 18, it squeezes the side surface of the driving rotary cover 4, causing the top end of the driving rotary cover 4 to move upward and squeeze the top end of the air jet gun rod 6. At the same time, the motor drives the driving rotary cover 4 to rotate, which can drive the air jet gun rod 6 on the annular support frame 22 to rotate around the processing head body 1. When the air jet gun rod 6 rotates around the axis of the rotating shaft tube 20 under pressure, the gas communication groove 21 will be communicated with the chip cleaning air cavity 7. At this time, the gas inhaled by the air pump 26 can enter the chip cleaning air cavity 7 through the air inlet hole 23, prompting the chip cleaning air cavity 7 to blow off the chips in the processing groove on the surface of the titanium alloy;

[0044] When the air jet gun rod 6 rotates around the axis of the rotating shaft tube 20, the toggle disk 10 will squeeze the auxiliary drive rod 9. The auxiliary drive rod 9 is pressed and moves downward, squeezing the anti-splash nozzle 14 through the finger pressure plates 11, prompting the anti-splash nozzle 14 to unfold. When the anti-splash nozzle 14 unfolds, it will cause the docking hole 16 to be communicated with the anti-splash air jet cavity 17 to eject gas, preventing titanium alloy chips from splashing.

[0045] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
