Description

Technical Field

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

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

[0003] However, when the existing air gun is used in conjunction with a cutter body or a drill bit to process titanium alloy, the air gun is fixed in position and cannot effectively blow away the debris in the gap of the titanium alloy workpiece, thereby affecting the smoothness of the titanium alloy processing. At the same time, when the titanium alloy debris is blown away by the air gun, it is easy to cause powdered titanium alloy debris to float and block or flaky titanium alloy debris to splash randomly, which is not conducive to the staff's later cleaning of the titanium alloy powder and debris in the processing equipment. Summary of the invention

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A cleaning device for deep processing of titanium alloys, comprising a processing head body and a bottom shield, wherein a cavity is provided inside the bottom shield, and a plurality of waste collection grooves arranged in a ring 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, the top end of the processing head body is connected to a mechanical arm through a telescopic component, a driving rotating cover is tightly fitted on the top side of the shell of the processing head body, six arc-shaped butt joints are provided on the top side of the driving rotating cover, and the top ends of the six arc-shaped butt joints are connected to an air jet gun rod through a butt joint groove, and the air jet gun rod is L-shaped, an air supply component is sleeved on the middle part of the air jet gun rod, a surrounding component is provided on the inner side of the air supply component, and one end of the surrounding component The end is connected to the processing head body through a supporting assembly, a chip cleaning air cavity and an assembly cavity are provided inside the jet gun rod, the inner bottom wall of the assembly cavity is connected to a sub-driving rod through a reset assembly, the top arc surface of the sub-driving rod is tightly fitted with a toggle disk, three finger pressure plates are fixed to the side of the sub-driving rod, an air guide tube is fixed to the inner wall of the countersunk hole provided on the outside of the jet gun rod, an air distribution channel is provided in the middle of the gun rod of the jet gun rod, and the chip cleaning air cavity is connected with the air guide tube through the air distribution channel, an anti-splash nozzle is sleeved on the outside of the air guide tube, displacement grooves are provided on the outsides of the three anti-splash nozzles, a docking hole is provided on the side of the air guide tube, an anti-splash jet cavity is provided at one end of the anti-splash nozzle, and the anti-splash jet cavity is fan-shaped.

[0006] 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.

[0007] 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.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] Preferably, the reset assembly comprises a reset spring fixed between the bottom wall of the assembly cavity and the bottom end of the auxiliary driving rod, and the assembly cavity is adapted to the auxiliary driving rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 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.

[0014] 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.

[0015] 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.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Example, see Figures 1 to 9 A cleaning device for deep processing of titanium alloy comprises a processing head body 1 and a bottom shield 2, a cavity is provided inside the bottom shield 2, a plurality of waste collection grooves 3 arranged in a circular array are provided on the inner side wall of the bottom shield 2, and one end of the waste collection groove 3 is communicated with the cavity of the bottom shield 2, the top of the processing head body 1 is connected to the robot arm through a telescopic assembly, further, the telescopic assembly comprises a robot arm connector 18 sleeved on the top convex edge of the processing head body 1, a compression spring 19 is fixed between the bottom of the robot arm connector 18 and the upper surface of the processing head body 1, and the lower surface of the robot arm connector 18 is rotatably connected to the base surface of the driving rotating cover 4.

[0022] A further advantage of adopting the above method is that the bottom channel of the bottom shield 2 is connected to an exhaust device, through which the aluminum alloy powder and debris blown out by the jet gun rod 6 and the splash-proof nozzle 14 can be quickly extracted into a 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 and driving the rotating cover 4, driving the compressed top end of the rotating cover 4 to move upward, squeezing the jet gun rod 6 to rotate through the arc-shaped docking joint 5, and causing the bottom of the jet gun rod 6 to move toward the processing end of the processing head body 1.

[0023] A driving rotating cover 4 is tightly fitted on the top side of the shell of the processing head body 1, and six arc-shaped docking joints 5 are provided on the top side of the driving rotating cover 4. The top ends of the six arc-shaped docking joints 5 are connected to the jet gun rod 6 through docking grooves, and the jet gun rod 6 is arranged in an L shape, and the middle part of the jet gun rod 6 is sleeved with an air supply assembly. Furthermore, the air supply assembly includes a rotating shaft tube 20 sleeved on the middle part of the jet gun rod 6, a gas connecting groove 21 is opened on the side of the rotating shaft tube 20, annular support frames 22 are arranged at both ends of the rotating shaft tube 20, six air inlet holes 23 are opened on the top of the annular support frame 22, and the bottoms of the six air inlet holes 23 are connected through the rotating shaft tube 20, and an air pump 26 is inserted at the top of the six air inlet holes 23.

[0024] A further advantage of adopting the above method is that the driving rotating cover 4 is driven to rotate by a motor, and the main body of the driving rotating cover 4 is a flexible plate, which can be deformed under the extrusion of the processing head body 1, and the top end moves up to squeeze the jet gun rod 6. Because the arc-shaped docking joint 5 is connected to the jet gun rod 6 in a slot-type manner, the arc-shaped docking joint 5 and the jet gun rod 6 can still be connected in the slot when the driving rotating cover 4 is deformed. Therefore, when the driving rotating cover 4 rotates, the jet gun rod 6 can be driven to rotate with it, and the jet gun rod 6 itself will rotate with the rotating shaft tube 20 as the axis. When the jet gun rod 6 rotates, it will be connected with the gas connecting groove 21 on the side of the rotating shaft tube 20, so that the gas sucked into the air inlet 23 by the air pump 26 is ejected from the chip cleaning air cavity 7.

[0025] A surrounding component is provided on the inner side of the air supply component. Further, the surrounding component includes a bent pipe frame 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 frame 24 .

[0026] A further advantage of adopting the above method is that the bent pipe frame 24 can ensure the rotation of the annular support frame 22, because the rotation of the rotating cover 4 will drive the jet gun rod 6 on the annular support frame 22 to rotate, so the annular support frame 22 will also rotate.

[0027] One end of the surround assembly is connected to the processing head body 1 through the support assembly. Furthermore, the support assembly includes a leg plate 27 inserted into one end of the connecting socket 25. One end of the leg plate 27 is tightly fitted to the outer side of the processing head body 1. The inner wall of the leg plate 27 is threadedly connected with an adjusting bolt 28. One end of the adjusting bolt 28 is connected to the inner wall of the countersunk hole of the connecting socket 25 through a bearing.

[0028] A further advantage of adopting the above method is that rotating the adjusting bolt 28 can change the cross length between the connecting base 25 and the leg plate 27 , so that the annular support frame 22 can be connected to the processing head body 1 through the leg plate 27 and the connecting base 25 .

[0029] A chip cleaning air chamber 7 and an assembly chamber 8 are provided inside the jet gun rod 6. The inner bottom wall of the assembly chamber 8 is connected to a secondary driving rod 9 via a reset assembly. Furthermore, the reset assembly includes a reset spring 29 fixed between the inner bottom wall of the assembly chamber 8 and the bottom end of the secondary driving rod 9. The assembly chamber 8 is adapted to the secondary driving rod 9.

[0030] A further advantage of adopting the above method is that the reset spring 29 can drive the auxiliary driving rod 9 to reset, thereby losing the supporting effect on the anti-splash nozzle 14, so that the anti-splash nozzle 14 is reset under the action of its own gravity.

[0031] The top arc surface of the auxiliary driving rod 9 is tightly fitted with a toggle plate 10, and three finger pressure plates 11 are fixed to the side of the auxiliary driving rod 9. An air guide tube 12 is fixed to the inner wall of the countersunk hole opened on the outside of the jet gun rod 6, and an air distribution channel 13 is opened in the middle of the gun rod of the jet gun rod 6, and the chip cleaning air cavity 7 is connected with the air guide tube 12 through the air distribution channel 13. An anti-splash nozzle 14 is sleeved on the outside of the air guide tube 12, and displacement grooves 15 are opened on the outside of the three anti-splash nozzles 14. A docking hole 16 is opened on the side of the air guide tube 12, and an anti-splash jet cavity 17 is opened at one end of the anti-splash nozzle 14, and the anti-splash jet cavity 17 is arranged in a fan shape.

[0032] After the jet gun rod 6 rotates, it will cause the toggle plate 10 to squeeze the secondary driving rod 9, and the secondary driving rod 9 will move downward under pressure, and the anti-splash nozzle 14 will be driven to rotate through the finger pressure plate 11, so that the anti-splash nozzle 14 will expand to form an arc-shaped wind wall to prevent the titanium alloy debris from splashing. The anti-splash jet cavity 17 is fan-shaped and can make the gas ejected by the six anti-splash nozzles 14 form a complete arc surface to prevent the titanium alloy debris from splashing (the wind belt has a large multi-layer stacking thickness, and the debris cannot effectively pass through the wind belt. The anti-splash nozzle 14 is arranged on the processing head body 1, when the debris splashes and contacts the wind belt, it will be blown to the edge of the wind belt and diffused. During the diffusion process, it will be sucked away by the waste collection groove 3 opened on the inner wall of the bottom shield 2. The suction force of the waste collection groove 3 cooperates with the blowing force of the splash-proof nozzle 14 to form a wind conveyor belt to extract the debris in time). The angle of the displacement groove 15 opened on the splash-proof nozzle 14 increases from top to bottom, so that the gas ejected after the three splash-proof nozzles 14 are deployed forms a multi-layer stacked arc surface, thereby improving the effect of blocking titanium alloy debris.

[0033] When the present invention is used, the robot arm drives the robot arm connector 18 to move downward, and the processing head body 1 moves downward accordingly. After contacting the titanium alloy workpiece, the processing head body 1 is compressed and shrinks close to the robot arm connector 18. After the processing head body 1 is close to the robot arm connector 18, it squeezes and drives the side of the rotating cover 4, prompting the top of the rotating cover 4 to move upward and squeeze the top of the jet gun rod 6. At the same time, the motor drives the rotating cover 4 to rotate, which can drive the jet gun rod 6 on the annular support frame 22 to rotate around the processing head body 1. When the jet gun rod 6 is compressed and rotates with the rotating shaft tube 20 as the axis, the gas connecting groove 21 is connected to the chip cleaning air cavity 7. At this time, the gas sucked in by the air pump 26 can enter the chip cleaning air cavity 7 through the air inlet 23, prompting the chip cleaning air cavity 7 to blow away the debris in the titanium alloy surface processing groove; When the jet gun rod 6 rotates with the shaft tube 20 as the axis, the dial 10 will squeeze the sub-driving rod 9, and the sub-driving rod 9 will move downward under pressure, squeezing the anti-splash nozzle 14 through the finger pressure plate 11, so that the anti-splash nozzle 14 will be expanded. When the anti-splash nozzle 14 is expanded, the docking hole 16 will be connected with the anti-splash jet cavity 17 to spray gas, thereby preventing titanium alloy debris from splashing.

[0034] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
