Description

Technical Field

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

[0002] There are specific usage requirements for the nozzles of aviation piping systems, requiring the application of 2.5mm wide red tape. The main function of this tape is to limit the positioning of the nozzle connectors; that is, the installation position of the connectors must be within a 2.5mm width range of the red line, and the tolerance for the 2.5mm width is specified as ±0.5.

[0003] The limited market supply of 2.5mm wide tape makes it impossible to directly purchase tape of this specific width, causing great inconvenience to the production and manufacturing of aerospace piping systems.

[0004] To meet the aforementioned usage requirements, the only option is to purchase 50mm wide tape and then cut it into 2.5mm wide tape.

[0005] Currently, most 2.5mm wide tapes are cut manually using a cutting tool. Manual operation makes it difficult to precisely control the cutting width, and it is hard to consistently control the tape width at 2.5mm with a tolerance within ±0.5mm. Moreover, during manual cutting, problems such as uneven tape edges are prone to occur. Uneven tape edges will affect the adhesion between the tape and the tube opening, thus affecting the quality of the tape.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a tape cutting device for aerospace piping systems, solving the problem that existing technologies mostly involve manual cutting of 2.5mm wide tape using a cutting tool. Manual operation makes it difficult to precisely control the cutting width, and the manual cutting process easily results in uneven tape edges, which affect the adhesion between the tape and the pipe opening, thus impacting the tape quality. The preferred technical solutions provided by this utility model offer numerous technical advantages, which are detailed below.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This utility model provides a tape cutting device for an aviation pipe system, including a base, a tape mechanism and a cutting mechanism disposed on the base. The tape mechanism is used to install tape. The cutting mechanism includes a blade and a cutting bracket for installing the blade. The base has a receiving groove for accommodating the cutting bracket. The receiving groove has a limiting groove on the side plate near the tape mechanism. There are multiple limiting grooves arranged sequentially along the width direction of the tape. The distance between two adjacent limiting grooves is 2.5 mm. The cutting bracket is provided with a limiting piece adapted to the limiting groove. The receiving groove has a plurality of tightening holes on the side plate away from the tape mechanism. The tightening holes are arranged along the moving direction of the cutting bracket. Tightening screws pass through the tightening holes and abut against the cutting bracket.

[0010] Preferably, the central axis of the limiting piece extending through its thickness direction coincides with the central axis of the blade extending through its thickness direction.

[0011] Preferably, a booster is provided on the non-cutting end of the blade.

[0012] Preferably, the cutting bracket is provided with a clamping groove for mounting the blade and the pusher; the clamping groove is inclined upward in the direction toward the tape mechanism.

[0013] Preferably, a sliding groove is provided on the side plate of the clamping groove, the sliding groove is arranged parallel to the clamping groove, and the pusher is provided with a positioning through hole that matches the sliding groove.

[0014] Preferably, the side plate of the clamping groove is provided with a plurality of tightening holes, which are arranged sequentially along the extension direction of the clamping groove, and the tightening screw passes through the tightening hole and abuts against the blade.

[0015] Preferably, the tape mechanism includes a tape support, a rotating component, a rotating disk, a handle, and a clamping component. The tape support includes a split first support and a second support, both of which are connected to the base by bolts. The rotating component has a rotating shaft, a first connecting part, a mounting part, and a second connecting part arranged sequentially along its axial direction. The handle is disposed on the rotating disk, which is fixedly connected to the rotating shaft. The first connecting part is rotatably connected to the first support via a bearing, and the second connecting part is detachably mounted on the second support via a bearing. A limiting protrusion is provided on the side of the mounting part near the first support, and the clamping component is detachably mounted on the mounting part for applying a clamping force to the tape toward the limiting protrusion.

[0016] Preferably, the clamping member is a ring structure, and the clamping member is provided with a plurality of connecting holes, which are arranged at intervals along its circumference, and the screws are connected to the side plate of the mounting part through the connecting holes.

[0017] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0018] This invention effectively avoids the problems existing in the prior art where 2.5mm wide tape is mostly cut manually with a tool knife. Manual operation makes it difficult to accurately control the cutting width. Moreover, during manual cutting, problems such as uneven tape edges are easy to occur. Uneven tape edges will affect the adhesion between the tape and the tube opening, thus affecting the quality of the tape.

[0019] This utility model provides a tape cutting device for an aviation pipe system, including a base, a tape mechanism and a cutting mechanism disposed on the base. The tape mechanism is used to install tape; the cutting mechanism includes a blade and a cutting bracket for installing the blade.

[0020] This invention, by setting multiple 2.5mm-spaced limiting grooves on the base and corresponding limiting pieces on the cutting bracket, can precisely adjust the position of the cutting bracket and accurately control the cutting position of the blade on the tape. This ensures that the width of the cut tape is consistently controlled at 2.5mm, meeting the tape width requirements of aerospace piping systems. Furthermore, after the cutting bracket is adjusted to the appropriate position, a tightening screw is passed through the tightening hole and abuts against the cutting bracket. Tightening the tightening screw firmly fixes the cutting bracket within the receiving groove, preventing movement during the cutting process and ensuring cutting accuracy.

[0021] This invention improves the flatness of the tape edges and increases production efficiency by using mechanical cutting compared to manual cutting. Attached Figure Description

[0029] 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.

[0030] like Figures 1-4As shown, this utility model provides a tape cutting device for an aviation pipe system, including a base 1, a tape 16 mechanism and a cutting mechanism disposed on the base 1. The tape 16 mechanism is used to install a 50mm wide tape 16. The cutting mechanism includes a blade 4 and a cutting bracket 2 for installing the blade 4. A receiving groove 101 is provided on the base 1 to accommodate the cutting bracket 2. A limiting groove 1011 is provided on the side plate of the receiving groove 101 near the tape 16 mechanism. There are multiple limiting grooves 1011, which are arranged sequentially along the width direction of the tape 16. The distance between two adjacent limiting grooves 1011 is 2.5mm. A limiting piece 3 adapted to the limiting groove 1011 is provided on the cutting bracket 2. A plurality of tightening holes 1012 are provided on the side plate of the receiving groove 101 away from the tape 16 mechanism. The tightening holes 1012 are arranged along the moving direction of the cutting bracket 2. The tightening screw 12 passes through the tightening hole 1012 and abuts against the cutting bracket 2.

[0031] This invention, by setting multiple limiting grooves 1011 with a spacing of 2.5mm on the base 1 and corresponding limiting pieces 3 on the cutting bracket 2, can precisely adjust the position of the cutting bracket 2. Specifically, by inserting the limiting pieces 3 into different limiting grooves 1011, the position of the cutting bracket 2 can be precisely adjusted, thereby determining the position of the blade 4 cutting the tape 16 to meet the requirement of cutting 50mm wide tape 16 into 2.5mm wide tape 16. This ensures that the width of the cut tape 16 is stably controlled at 2.5mm, meeting the requirements of aerospace piping systems for the width of the tape 16. Furthermore, after the cutting bracket 2 is adjusted to the appropriate position, the tightening screw 12 is passed through the tightening hole 1012 and abuts against the cutting bracket 2. By tightening the tightening screw 12, the cutting bracket 2 is firmly fixed in the receiving groove 101, preventing movement of the cutting bracket 2 during the cutting process and ensuring cutting accuracy.

[0032] This invention improves the flatness of the edges of the tape 16 after cutting by using mechanical cutting, compared with manual cutting, thus increasing production efficiency.

[0033] As an optional implementation, the central axis of the limiting piece 3 extending through its thickness direction coincides with the central axis of the blade 4 extending through its thickness direction.

[0034] With this configuration, when the cutting bracket 2 is positioned by inserting the limiting piece 3 into the limiting groove 1011, the position of the blade 4 is also precisely determined, so that the width of the cut tape 16 can be stably controlled at 2.5mm.

[0035] As an optional implementation, a booster 5 is provided on the non-cutting end of the blade 4.

[0036] Furthermore, the booster 5 has a T-shaped structure, and its small end has a slot for clamping the blade 4.

[0037] As an optional implementation, the cutting bracket 2 is provided with a clamping groove 201 for mounting the blade 4 and the pusher 5; the clamping groove 201 is inclined upward in the direction toward the tape 16 mechanism.

[0038] Furthermore, the clamping groove 201 includes a first clamping part 2011 and a second clamping part 2012 that are connected. The clamping width of the first clamping part 2011 is greater than the clamping width of the second clamping part 2012. The first clamping part 2011 is used to clamp the pusher 5, and the second clamping part 2012 is used to clamp the blade 4, so that the pusher 5 and the blade 4 are more stable in the clamping groove 201.

[0039] The clamping groove 201 is inclined so that the blade 4 can cut into the tape 16 at an inclined angle during cutting, thereby improving cutting efficiency.

[0040] Operators can use auxiliary tools such as hammers to strike the large end of the pusher 5, pushing the small end of the pusher 5 to move along the first clamping part 2011 toward the tape 16, thereby adjusting the position of the blade 4 so that the cutting depth of the tape 16 can be adjusted according to the required amount, and one or more layers can be cut at a time.

[0041] As an optional implementation, the first clamping part 2011 has a sliding groove 20111 on both sides of the side plate. The sliding groove 20111 is arranged parallel to the clamping groove 201. The small end of the pusher 5 has a positioning through hole on both sides of the side plate that is adapted to the sliding groove 20111.

[0042] When the pusher 5 moves the blade 4, the relative position of the positioning through hole and the slide 20111 changes. After the blade 4 is adjusted to the appropriate position, the operator passes the positioning pin 14 through the slide 20111 and the positioning through hole to firmly fix the pusher 5 in the first clamping part 2011 to prevent the blade 4 from moving during the cutting process.

[0043] As an optional implementation, the side plate of the second clamping part 2012 is provided with a plurality of tightening holes 20121, which are arranged sequentially along the extension direction of the clamping groove 201, and the tightening screw 13 passes through the tightening hole 20121 and abuts against the blade 4.

[0044] After the blade 4 is adjusted to the appropriate position, the operator passes the tightening screw 13 through the tightening hole 20121, so that the end of the tightening screw 13 abuts against the blade 4. The tightening screw 13 applies pressure to the blade 4, and firmly fixes the blade 4 in the second clamping part 2012 to prevent the blade 4 from moving during the cutting process.

[0045] When the position of blade 4 needs to be adjusted again, first loosen the tightening screw 13 so that blade 4 can move relative to it. After adjusting it to a new suitable position, tighten the tightening screw 13 again to fix blade 4 in place to meet different cutting needs.

[0046] As an optional embodiment, the tape 16 mechanism includes a tape 16 support, a rotating component 8, a rotating disk 9, a handle 10, and a clamping component 11. The tape 16 support includes a split first support 6 and a second support 7, both of which are connected to the base 1 by bolts. The rotating component 8 has a rotating shaft portion 801, a first connecting portion 802, a mounting portion 803, and a second connecting portion 804 arranged sequentially along its axial direction. The handle 10 is disposed on the rotating disk 9, which is fixedly connected to the rotating shaft portion 801. The first connecting portion 802 is rotatably connected to the first support 6 via a bearing 17, and the second connecting portion 804 is detachably disposed on the second support 7 via a bearing 17. A limiting protrusion ring 8031 ​​is provided on the side of the mounting portion 803 near the first support 6, and the clamping component 11 is detachably disposed on the mounting portion 803 for applying a clamping force toward the limiting protrusion ring 8031 ​​to the tape 16.

[0047] Furthermore, the first connecting portion 802 and the second connecting portion 804 have a stepped structure, and their small ends are rotatably connected to the first support 6 and the second support 7 respectively via bearings 17. The large ends of both the first connecting portion 802 and the second connecting portion 804 are connected to the mounting portion 803, and their diameters are smaller than the diameter of the mounting portion 803. The small end of the first connecting portion 802 is connected to the rotating shaft portion 801, and the diameter of the rotating shaft portion 801 is smaller than the diameter of the small ends of the first connecting portion 802 and the second connecting portion 804.

[0048] The limiting protrusion ring 8031 ​​and the clamping member 11 protrude from the mounting part 803 and are adapted to the width of the paper roll of the tape 16 so that they can abut against the paper roll of the tape 16.

[0049] First, the tape 16 is fitted onto the mounting part 803, with one side of the paper roll of the tape 16 abutting against the limiting protrusion 8031 ​​for initial positioning. Then, the clamping member 11 is fitted onto the mounting part 803, and the clamping member 11 applies a clamping force to the other side of the paper roll of the tape 16 toward the limiting protrusion 8031. Through the cooperation of the limiting protrusion 8031 ​​and the clamping member 11, the tape 16 can be effectively fixed on the mounting part 803 of the rotating member 8, improving the positional accuracy of the tape 16 during the cutting process.

[0050] The operator turns the handle 10 to drive the rotating disk 9 to rotate, which in turn drives the rotating part 8 to rotate, and the tape 16 rotates accordingly to facilitate the cutting operation.

[0051] As an optional implementation, the clamping member 11 has a ring structure and is provided with a plurality of connecting holes. The connecting holes are arranged at intervals along its circumference, and the connecting screws 15 are connected to the side plate of the mounting part 803 through the connecting holes.

[0052] The clamping member 11 is securely fixed to the mounting part 803 by the cooperation of the connecting hole and the connecting screw 15.

[0053] When tape 16 needs to be replaced, first separate the second support 7 from the base 1, so that the second connecting part 804 is separated from the second support 7. Then loosen the connecting screw 15, remove the clamping part 11, and remove the old tape 16 from the mounting part 803. Then install the new tape 16, and repeat the above tape 16 installation steps to complete the replacement of tape 16.
