Description

Technical Field

[0001] This invention relates to the field of titanium alloy panel processing technology, specifically to an automatic flanging and drilling robot for titanium alloy panels. Background Technology

[0002] With the rapid development of the aviation industry, the market demand for aircraft is also increasing. In order to meet the current and future market demands, simply expanding the scale of production is not enough. It is necessary and urgent to improve the level of automated assembly in factories by developing some specialized equipment.

[0003] Titanium alloy panels are widely used in aircraft, launch vehicle tanks, and manned spacecraft cabins. Due to differences in their respective uses, environments, and reliability requirements, the panel structures vary considerably. When processing titanium alloy panels, especially in drilling holes and flanging the edges of the drilled holes, most of the work is done manually in steps, requiring repeated loading, unloading, and calibration. This process is complex, has a low degree of automation, and is inefficient.

[0004] Therefore, the present invention provides an automatic flanging and drilling robot for titanium alloy panels, which can automatically drill holes in titanium alloy panels and simultaneously flanging the edges of the drilled holes. Summary of the Invention

[0005] To solve the above technical problems.

[0006] This application provides an automatic flanging and drilling robot for titanium alloy wall panels, including: a frame, a flanging mechanism and a drilling mechanism. The drilling mechanism is mounted on the frame via a vertical frame, and the flanging mechanism is mounted on the worktable of the frame. The flanging mechanism is located directly below the drilling mechanism, and an auxiliary mechanism that can assist in drilling and flanging is mounted on the vertical frame.

[0007] The flanging mechanism includes a rotary drive component and a flanging shaft. The rotary drive component is mounted on the frame via a fixed base, and the flanging shaft is fixedly mounted on the output end of the rotary drive component. The rotary drive component can drive the flanging shaft to rotate upward or downward.

[0008] The drilling mechanism includes a drilling assembly and a pressure plate shaft head. The drilling assembly is vertically mounted on the frame via a hydraulic push rod assembly and a slide. The output end of the hydraulic push rod assembly is fixedly connected to the slide. The slide is mounted on the frame via a lifting slide rail. The drilling assembly is fixedly mounted on the slide. The pressure plate shaft head is mounted at the lower end of the drilling assembly. The drill bit of the drilling assembly can extend and retract and can pass through the pressure plate shaft head.

[0009] Furthermore, a pre-pressure head is installed at the lower end of the pressure plate shaft head, which can press the titanium alloy wall panel to be processed.

[0010] During operation, the hydraulic push rod assembly pushes the slide, drilling assembly, and pressure plate shaft head close to the titanium alloy wall panel to be processed. The pre-pressure head of the pressure plate shaft head presses the titanium alloy wall panel tightly. The drilling assembly starts, causing the drill bit to extend from the pressure plate shaft head to drill a hole in the titanium alloy wall panel. After drilling is completed, the drill bit retracts into the pressure plate shaft head. The hydraulic push rod assembly further pushes the pressure plate shaft head and pre-pressure head downwards, and the pre-pressure head bends the edge of the drilled hole downwards.

[0011] Furthermore, the flange shaft is fitted with an outer cover, which is fixedly mounted on a fixed base. The upper end of the outer cover has a drill hole for drilling, the diameter of which matches the diameter of the pre-pressure head. The outer cover has a double-layer hollow structure and is connected to the air intake assembly. The hole wall of the drill hole has air holes, which are connected to the hollow layer of the outer cover and the air intake assembly.

[0012] Furthermore, a flange head is screwed onto the top of the flange shaft. The flange head forms an arc-shaped flared mouth from top to bottom, and the diameter of the top of the flange head is smaller than the diameter of the drilled hole.

[0013] Furthermore, the auxiliary mechanism is installed on both sides of the upright frame via auxiliary frames. Each auxiliary frame is equipped with a clamping component. Each clamping component is connected to the corresponding auxiliary frame via a connecting component. The connecting components are connected to the upright frame via cylinders. The cylinders are fixedly installed on the upright frame and their output ends are fixedly connected to the connecting components. The two connecting components are connected by a guide rod group. The two ends of the guide rod group are respectively fixedly installed on the two auxiliary frames.

[0014] Furthermore, the connecting assembly includes a connecting seat and a connecting plate. The connecting seat is slidably connected to the auxiliary frame via a rail seat. The rail seat is fixedly installed on the auxiliary frame. The rail seat and the connecting plate are connected via a rail. The connecting plate is fixedly connected to the output end of the cylinder. A guide groove is provided in the connecting seat. The guide groove and the rail are slidably connected via a guide head. The guide head is fixedly installed on the upper end of the rail. The clamping assembly is fixedly installed on the corresponding connecting seat.

[0015] Furthermore, the clamping assembly includes a clamping head and a connecting rod. The connecting rod is fixedly installed on the connecting seat, and the clamping head is inserted into the connecting rod. An air outlet is provided inside the clamping head, and the air outlet of the clamping head is connected to the connecting rod and an external air source. The clamping head and the connecting rod are connected by a spring, which is sleeved on the outside of the clamping head. The two ends of the spring abut against the connecting rod and the clamping head, respectively, and the air outlet of the clamping head faces the drilling area.

[0016] Furthermore, the lower end of the connecting rod is fitted with a buckle for engaging the coolant pipe and the pipe head.

[0017] Furthermore, a limiting groove is provided on the connecting seat, and the limiting groove is connected to the auxiliary frame through a limiting head. The limiting head is fixedly installed on the auxiliary frame, and the limiting head and the limiting groove are slidably connected.

[0036] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0037] like Figures 1 to 8 As shown, the following preferred technical solutions are provided:

[0038] An automatic flanging and drilling robot for titanium alloy wall panels 5 includes: a frame 1, a flanging mechanism 3 and a drilling mechanism 2. The drilling mechanism 2 is mounted on the frame 1 via a stand 1b. The flanging mechanism 3 is mounted on the workbench 1a of the frame 1 and is located directly below the drilling mechanism 2. An auxiliary mechanism 4 that can assist in drilling and flanging is mounted on the stand 1b.

[0039] The flanging mechanism 3 includes a rotatable drive component 3a and a flanging shaft 3b. The rotatable drive component 3a is mounted on the frame 1 via a fixed base 3e. The flanging shaft 3b is fixedly mounted on the output end of the rotatable drive component 3a. The rotatable drive component 3a can drive the flanging shaft 3b to rotate upward or downward.

[0040] The drilling mechanism 2 includes a drilling assembly 2d and a pressure plate shaft head 2e. The drilling assembly 2d is vertically mounted on the frame 1b via a hydraulic push rod assembly 2a and a slide 2c. The output end of the hydraulic push rod assembly 2a is fixedly connected to the slide 2c. The slide 2c is mounted on the frame 1b via a lifting slide rail 2b. The drilling assembly 2d is fixedly mounted on the slide 2c. The pressure plate shaft head 2e is mounted at the lower end of the drilling assembly 2d. The drill bit of the drilling assembly 2d can extend and retract and can pass through the pressure plate shaft head 2e.

[0041] Specifically, in order to solve the technical problems of drilling holes in titanium alloy wall panels 5 and flanging the edges of the drilled holes, this invention uses a drilling mechanism 2 to drill holes in titanium alloy wall panels 5. After drilling, a flanging mechanism 3 is used to flanging the edges of the drilled holes. During the drilling and flanging process, an auxiliary mechanism 4 is used to press the titanium alloy wall panels 5 together, and can also clean up the waste chips from the drilling and cool the drill bit. This solves the technical problem of the difficulty in flanging the edges of the holes, has a high degree of automation, and improves the drilling and flanging efficiency of titanium alloy wall panels 5.

[0042] like Figures 1 to 8 As shown, the following preferred technical solutions are provided:

[0043] A pre-pressing head 2e1 is installed at the lower end of the pressure plate shaft head 2e. The pre-pressing head 2e1 can press the titanium alloy wall plate 5 to be processed.

[0044] During operation, the hydraulic push rod assembly 2a pushes the slide block 2c, the drilling assembly 2d, and the pressure plate shaft head 2e close to the titanium alloy wall plate 5 to be processed. The pre-pressure head 2e1 of the pressure plate shaft head 2e presses the titanium alloy wall plate 5 tightly. The drilling assembly 2d is activated, causing the drill bit to extend from the pressure plate shaft head 2e to drill a hole in the titanium alloy wall plate 5. After drilling is completed, the drill bit retracts into the pressure plate shaft head 2e. The hydraulic push rod assembly 2a further pushes the pressure plate shaft head 2e and the pre-pressure head 2e1 downwards. The pre-pressure head 2e1 bends the edge of the drilled hole downwards.

[0045] Specifically, in order to solve the technical problem of drilling holes in titanium alloy wall panel 5, the present invention drives the drilling assembly 2d to rise and fall through the hydraulic push rod assembly 2a, uses the pressure plate shaft head 2e to position and press the drilling area, and after drilling is completed, the pressure plate shaft head 2e is further pressed down, and the pre-pressure head 2e1 pre-presses and bends the drilled edge to prepare for the flanging mechanism 3.

[0046] like Figures 5 to 8 As shown, the following preferred technical solutions are provided:

[0047] The flange shaft 3b is fitted with an outer cover 3c, which is fixedly mounted on the fixed base 3e. The upper end of the outer cover 3c has a drill inlet hole 3c1, the diameter of which matches the diameter of the preload head 2e1. The outer cover 3c has a double-layer hollow structure and is connected to the air intake assembly 3d. The hole wall of the drill inlet hole 3c1 has an air hole 3c2, which is connected to the hollow layer of the outer cover 3c and the air intake assembly 3d.

[0048] Specifically, in order to solve the technical problems of drill bit entry and pre-pressing the hole edge, the present invention uses the outer cover 3c as the working area for drilling. When the drill bit is aligned with the entry hole 3c1 and drills through the titanium alloy plate, the air intake component 3d blows air onto the drill bit through the air hole 3c2 in the hollow layer of the outer cover 3c, blowing off the waste chips attached to the surface of the drill bit and drying and cooling the surface of the drill bit. When the drill bit retracts from the self-pressure plate shaft head 2e, the pre-pressing head 2e1 moves downward and cooperates with the outer cover 3c and the entry hole 3c1 to pre-press and bend the hole edge.

[0049] like Figure 7 and Figure 8 As shown, the following preferred technical solutions are provided:

[0050] The top of the flanging shaft 3b is screwed with a flanging head 3b1, which forms an arc-shaped flared mouth from top to bottom. The diameter of the top of the flanging head 3b1 is smaller than the diameter of the drilled hole.

[0051] Specifically, in order to solve the technical problem of further flanging the pre-bent hole edge, the present invention uses a rotary drive assembly 3a to drive the flanging shaft 3b to rotate and rise. The flanging shaft 3b drives the flanging head 3b1 to extend upward into the drilled hole. The arc surface of the arc-shaped flared mouth of the flanging head 3b1 is used to press the pre-bent hole edge outward to achieve flanging.

[0052] like Figures 5 to 8 As shown, the following preferred technical solutions are provided:

[0053] The auxiliary mechanism 4 is installed on both sides of the upright frame 1b via auxiliary frames 4a. Each auxiliary frame 4a is equipped with a clamping component 4e. Each clamping component 4e is connected to the corresponding auxiliary frame 4a via a connecting component 4d. The connecting components 4d are all connected to the upright frame 1b via cylinders 4b. The cylinders 4b are fixedly installed on the upright frame 1b and their output ends are fixedly connected to the connecting components 4d. The two connecting components 4d are connected by a guide rod group 4c. The two ends of the guide rod group 4c are respectively fixedly installed on the two auxiliary frames 4a.

[0054] The connecting component 4d includes a connecting seat 4d1 and a connecting plate 4d7. The connecting seat 4d1 is slidably connected to the auxiliary frame 4a via a rail seat 4d2. The rail seat 4d2 is fixedly installed on the auxiliary frame 4a. The rail seat 4d2 and the connecting plate 4d7 are connected via a rail 4d3. The connecting plate 4d7 is fixedly connected to the output end of the cylinder 4b. A guide groove 4d5 is provided in the connecting seat 4d1. The guide groove 4d5 and the rail 4d3 are slidably connected via a guide head 4d4. The guide head 4d4 is fixedly installed on the upper end of the rail 4d3. The clamping component 4e is fixedly installed on the corresponding connecting seat 4d1.

[0055] Specifically, in order to solve the technical problem of driving the auxiliary mechanism 4 and the clamping assembly 4e, the present invention uses a cylinder 4b to push the connecting plate 4d7 and the rails 4d3 at both ends of the connecting plate 4d7. By utilizing the sliding of the rails 4d3 on the rail seat 4d2, the guide head 4d4 on the rails 4d3 slides with the guide groove 4d5 in the connecting seat 4d1, realizing the opposite movement between the two connecting seats 4d1, thereby driving the two clamping assemblies 4e to move towards each other, aligning the clamping assemblies 4e with the processing area.

[0056] like Figures 5 to 8 As shown, the following preferred technical solutions are provided:

[0057] The clamping assembly 4e includes a clamping head 4e1 and a connecting rod 4e2. The connecting rod 4e2 is fixedly installed on the connecting seat 4d1. The clamping head 4e1 is inserted into the connecting rod 4e2. An air outlet 4e4 is provided in the clamping head 4e1. The air outlet 4e4 of the clamping head 4e1 is connected to the connecting rod 4e2 and an external air source. The clamping head 4e1 and the connecting rod 4e2 are connected by a spring 4e5. The spring 4e5 is sleeved on the outside of the clamping head 4e1. The two ends of the spring 4e5 abut against the connecting rod 4e2 and the clamping head 4e1 respectively. The air outlet 4e4 of the clamping head 4e1 faces the drilling area.

[0058] Specifically, in order to solve the technical problem of further pressing the working area of ​​the titanium alloy wall panel 5, the present invention uses a pressing head 4e1 to press the titanium alloy wall panel 5. First, after the pressing head 2e of the drilling mechanism 2 initially presses the titanium alloy wall panel 5, the cylinder 4b pushes the connecting plate 4d7 and the connecting seat 4d1 to push the pressing rod to the processing area of ​​the titanium alloy wall panel 5. The spring 4e5 is used to realize the extension and retraction between the pressing head 4e1 and the connecting rod 4e2, thereby pressing the pressing head 4e1 against the titanium alloy wall panel 5. During drilling, air is blown onto the drill bit through the air outlet 3c2 of the pressing head 4e1 to clean the drilling area and prevent waste chips from accumulating around the drilled hole and affecting the flanging.

[0059] like Figure 6 and Figure 7 As shown, the following preferred technical solutions are provided:

[0060] The lower end of the connecting rod 4e2 is fitted with a clip 4e6 for engaging the coolant pipe and pipe head.

[0061] A limiting groove 4d6 is provided on the connecting seat 4d1. The limiting groove 4d6 is connected to the auxiliary frame 4a through a limiting head 4f.
