Description

Technical Field

[0001] This utility model relates to the field of aircraft processing technology, and in particular to a shearing device for aircraft supports. Background Technology

[0002] Support structures serve as crucial support and connection components in aerospace vehicles. Right-angle steel, a commonly used profile, is widely applied in the construction of various support structures due to its excellent mechanical properties and ease of processing.

[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] Currently, such as Figure 4 As shown, the shearing mechanism of right-angle steel can only cut the straight edge of the angle steel along the vertical direction. Its main function is limited to cutting the length of the angle steel and it cannot directly process the double-sided irregular cut surface required for splicing structure.

[0005] In the manufacturing of aircraft brackets, such as Figure 5 As shown, it is often necessary to make double-sided irregular cuts on two sets of angle steel, that is, one side plate of the angle steel is cut at 90° vertically and the other side plate is cut at 45° obliquely, so as to form a splicing structure to meet the assembly requirements of the bracket.

[0006] However, most existing methods for cutting double-sided irregular angle steel require manual operation using equipment to perform flat and oblique cuts on both sides of the right-angle angle steel. The cutting process is cumbersome, involves many manual operations, and requires constant manual adjustment of the cutting angle and position of the angle steel. This results in extremely high labor intensity, low production efficiency, and susceptibility to human factors, leading to unstable product quality.

[0007] In view of the above, this utility model is hereby proposed. Utility Model Content

This necessitates constant manual adjustment of the cutting angle and position of the angle steel, resulting in cumbersome, complex, time-consuming, labor-intensive, and inefficient operations, as well as low production efficiency. Furthermore, these methods are susceptible to human error, leading to unstable product quality. The preferred technical solutions provided by this utility model offer numerous technical advantages, which are detailed below.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

The bottom edge of the shearing opening is a V-shaped structure corresponding to the V-groove, and the top edge of the shearing opening is a W-shaped structure.

[0016] The auxiliary guide rail is detachably installed on at least one side of the V-shaped structure. The auxiliary guide rail has a guide groove that is adapted to the corner of the right-angled angle steel and is inclined so that the angle steel enters the V-shaped groove at an inclination. The shearing blade can cut one side plate of the angle steel at 45° and the other side plate at 90°.

[0017] Preferably, the second shear plate has multiple fixing holes a on both sides of the V-shaped structure, and the fixing holes a are arranged at intervals along the direction parallel to the inclined side of the V-shaped structure. The auxiliary guide rail has fixing holes b that are adapted to the fixing holes a.

[0018] Preferably, the upper surface of the auxiliary guide rail is provided with the guide groove, which extends downwards from the outside to the inside towards the concave part of the V-shaped structure, and forms a limiting space between the guide groove and a convex part of the W-shaped structure for the angle steel to enter the shearing channel.

[0019] Preferably, the drive mechanism includes an electric push rod, the fixed end of which is connected to the top plate of the frame, and the telescopic rod of which is connected to the shearing blade via a threaded sleeve.

[0024] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0025] This invention effectively avoids the technical problems existing in the prior art where the cutting of double-sided irregular angle steel mostly requires two manual cutting operations, which require constant manual adjustment of the cutting angle and position of the angle steel. This operation is cumbersome, time-consuming, labor-intensive, and has low production efficiency. It is also easily affected by human factors, leading to unstable product quality.

[0026] This utility model provides a shearing device for aircraft supports, including a frame, a drive mechanism, and a shearing mechanism. The shearing mechanism includes a shearing base, a shearing frame, a first shearing plate, a second shearing plate, an auxiliary guide rail, and a shearing blade. The shearing base is mounted on the base plate of the frame and is used to mount the shearing frame. The shearing frame has a V-shaped groove adapted to the right angle portion of the angle steel.

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0050] like Figures 1 to 3As shown, this utility model provides a shearing device for aircraft supports, including a frame 1, a drive mechanism, and a shearing mechanism. The shearing mechanism includes a shearing base 3, a shearing frame 4, a first shearing plate 5, a second shearing plate 6, an auxiliary guide rail 7, and a shearing blade 8. The shearing base 3 is mounted on the base plate 102 of the frame 1 and is used to mount the shearing frame 4. The shearing frame 4 has a V-groove 401 that matches the right angle portion of the angle steel 14. The first shearing plate 5 is detachably connected to one side of the shearing frame 4 via a connecting square post 10. The lower part of the first shearing plate 5 forms an M-shaped structure 501 and forms a shearing channel with the shearing frame 4. The drive mechanism is mounted on the frame 1 and is used to drive the shearing blade 8 to reciprocate in the vertical direction along the shearing channel. The shearing blade 8 has... A V-shaped blade 801 is adapted to the V-groove 401; the second shearing plate 6 is detachably connected to the other side of the shearing frame 4, and a shearing opening 601 is provided on the second shearing plate 6. The bottom edge of the shearing opening 601 is a V-shaped structure 6011 corresponding to the V-groove 401, and the top edge of the shearing opening 601 is a W-shaped structure 6012; an auxiliary guide rail 7 is detachably provided on at least one side of the V-shaped structure 6011, and a guide groove 701 is provided on the auxiliary guide rail 7 to adapt to the corner of the right angle steel 14 and be inclined, so that the angle steel 14 enters the V-groove 401 at an incline. The shearing blade 8 can cut one side plate of the angle steel 14 at 45° to form a bevel 1402, and the other side plate at 90° to form a straight edge 1401.

[0051] When only the length of angle steel 14 needs to be cut, the auxiliary guide rail 7 is not installed. In this case, the corner of angle steel 14 is placed directly onto the V-groove, and the drive mechanism drives the shearing blade 8 to move vertically downwards, cutting the angle steel 14 vertically to achieve length cutting. Figure 4 As shown. This operation method is simple and direct, and is suitable for basic length adjustment of angle steel 14.

[0052] When double-sided irregular cutting of angle steel 14 is required, the auxiliary guide rail 7 is installed on the corresponding side of the second shearing plate 6. The corner of angle steel 14 enters the V-groove at an incline along the guide groove 701. During this process, the guide groove 701 provides precise guidance for angle steel 14, allowing it to enter the shearing area at an incline angle. The shearing blade 8 moves downward under the drive of the drive mechanism. Due to the incline of angle steel 14, the shearing blade 8 can cut one side of angle steel 14 at 45° to form a bevel 1402, and the other side at 90° to form a straight edge 1401, thus achieving double-sided irregular cutting. Figure 5 As shown, it meets the special shape requirements of different parts of the aircraft support.

[0053] As an optional implementation, the second shear plate 6 has multiple fixing holes a602 on both sides of the V-shaped structure 6011, and the fixing holes a602 are arranged at intervals along the direction parallel to the inclined side of the V-shaped structure 6011. The auxiliary guide rail 7 has fixing holes b702 that are adapted to the fixing holes a602.

[0054] Fasteners such as bolts are passed through fixing holes b702 and a602 in sequence to securely fix the auxiliary guide rail 7 to the second shear plate 6, facilitating disassembly and assembly.

[0055] As an optional implementation, the upper surface of the auxiliary guide rail 7 is provided with a guide groove 701. The guide groove 701 extends downward from the outside to the inside toward the concave part of the V-shaped structure 6011, and forms a limiting space between it and a protrusion of the W-shaped structure 6012 for the angle steel 14 to enter the shearing channel.

[0056] Furthermore, it also includes a limiting screw 11. A limiting member 604 is provided above the protrusion of the W-shaped structure 6012 of the second shear plate 6. The limiting member 604 has a threaded hole that runs through the height direction of the second shear plate 6 and is adapted to the limiting screw 11. When the auxiliary guide rail 7 is installed on the second shear plate 6, its side plate can abut against the limiting screw 11.

[0057] When the angle steel 14 is placed on the auxiliary guide rail 7, it will slide down the inclined edge of the guide groove 701 and eventually enter the limiting space. At this time, one side of the angle steel 14 is in contact with the protrusion of the W-shaped structure, and the other side is restricted by the guide groove 701, preparing for the subsequent shearing operation.

[0058] As an optional implementation, the drive mechanism includes an electric push rod 2, the fixed end of which is connected to the top plate 101 of the frame 1, and the telescopic rod 201 of the electric push rod 2 is connected to the shearing blade 8 through a threaded sleeve 9.

[0059] Furthermore, the outer wall of the telescopic rod 201 is provided with an external thread section, and the inner wall of the threaded sleeve 9 is provided with an internal thread section that matches the external thread section.

[0060] The telescopic rod 201 of the electric push rod 2 is connected to the threaded sleeve 9 by the screw connection of the external thread section and the internal thread section.

[0061] When the electric push rod 2 is activated, the telescopic rod 201 will move in a straight line. Through the connection of the threaded sleeve 9, it will drive the shearing blade 8 to move back and forth in the vertical direction, thereby shearing the angle steel 14.

[0062] As an optional implementation, the connecting columns 10 are symmetrically arranged on both sides of the shearing frame 4 and welded to the shearing frame 4; the connecting columns 10 are provided with a plurality of first connecting holes a arranged sequentially along their height direction, and the first shearing plate 5 is provided with a first connecting hole b502 that matches the first connecting holes a.

[0063] Furthermore, the protrusion of the M-shaped structure 501 of the first shear plate 5 is correspondingly set with the concave part of the V-shaped groove 401.

[0064] Fasteners such as bolts are passed sequentially through the first connecting hole b502 and the first connecting hole a to securely fix the first shear plate 5 to the connecting column 10, facilitating disassembly, assembly, and position adjustment.

[0065] As an optional implementation, the second shearing plate 6 is provided with a plurality of second connecting holes a603 arranged sequentially along its height direction, and the shearing frame 4 is provided with second connecting holes b that are adapted to the second connecting holes a603.

[0066] The second shear plate 6 is securely fixed to the shear frame 4 by passing fasteners such as bolts through the second connecting hole a603 and the second connecting hole b in sequence, so as to facilitate disassembly, assembly and position adjustment.

[0067] As an optional implementation, the shear base 3 has U-shaped adjustment grooves 301 on both sides, and the base plate 102 has positioning holes. The adjustment screw 12 passes through the limiting nut 13 and the adjustment grooves 301 and is connected to the positioning holes on the base plate 102.

[0068] As an optional implementation, the width of the adjusting groove 301 is greater than the outer diameter of the screw, and the outer diameter of the limiting nut 13 is greater than the width of the adjusting groove 301.

[0069] Because the width of the adjusting groove 301 is greater than the outer diameter of the adjusting screw 12, the adjusting screw 12 has a certain amount of room to move within the adjusting groove 301. Since the outer diameter of the limiting nut 13 is greater than the width of the adjusting groove 301, the adjusting screw 12 applies pressure to the limiting nut 13 so that the limiting nut 13 can press against the surface of the shearing base 3, fixing the shearing base 3 to the base plate 102 and preventing the shearing base 3 from moving freely again after adjustment.

[0070] By loosening the adjusting screw 12, the shearing base 3 can be moved within a certain range. After adjusting its position, tightening the adjusting screw 12 can achieve fine adjustment of the position of the shearing base 3, so that the shearing blade 8 can move back and forth accurately along the shearing channel.
