Description

Technical Field

[0001] The utility model belongs to the field of cutting processing, and particularly relates to an auxiliary cutting device for cutting rubber strips. Background Art

[0002] In aircraft, rubber strips coated with special coatings are often used as fillers for parts to be sealed. As the equipment is used, the rubber strips are prone to aging, damage, etc., resulting in a decline in sealing performance and stealth status. At this time, the damaged part of the rubber strip needs to be cut and replaced.

[0003] In the prior art, workers draw cutting lines at both ends of the position to be cut through a ruler and cut according to the cutting lines. However, errors are likely to occur in this process, resulting in inaccurate cutting of the rubber strip, waste of materials, and the length adjustment of existing cutting tools is not fine enough, which is likely to damage the equipment or fail to completely cut the rubber strip during the cutting process. Moreover, during the process of reinstalling the rubber strip to the position to be replaced, there is no auxiliary fixture for fixing, resulting in the possibility of deformation or insecure pasting of the rubber strip, thus the replaced rubber strip fails to achieve a good sealing effect.

[0039] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0040] As Figure 1-9 shown: An auxiliary cutting device for cutting rubber strips, comprising:

[0041] A cutting assembly 1, in which a cutter for cutting rubber strips is provided.

[0042] An installation assembly 2, which is a structural member with a U-shaped cross-section. A working position for fixing the rubber strip is formed between the installation assembly 2 and the structure to which the rubber strip to be bonded is attached.

[0043] An auxiliary assembly 3, which is a structural member with a U-shaped cross-section. A scale 301 is provided on the outer sidewall of the auxiliary assembly 3.

[0044] The cross-sectional projection of the installation assembly 2 is the same as the cross-sectional projection of the auxiliary assembly 3.

[0045] The cutting assembly 1 includes:

[0046] A housing 101, with a moving cavity corresponding to a moving block 102 provided inside the housing 101. A rectangular hole 104 corresponding to a rotating column 103 is opened on the side wall of the moving cavity, and the rotating column 103 is located inside the rectangular hole 104;

[0047] A moving block 102, which is located inside the housing 101. External threads are provided on the side wall of the moving block 102, and a cutting tool is connected to one end of the moving block 102;

[0048] A rotating column 103, with a through hole opened along its axis. Internal threads corresponding to the external threads are provided inside the through hole, and the rotating column 103 is threadedly connected to the moving block 102.

[0049] The length of the cutting tool extending out is adjusted by the rotating column 103, and the threaded structure can provide a more precise length control function.

[0050] The housing 101 includes a bottom shell 10101, a top shell 10102, and a cover plate 10103; a first moving groove is opened on the bottom shell 10101, a second moving groove is opened on the top shell 10102, a third moving groove corresponding to the second moving groove is opened on the cover plate 10103, the cross-sectional projection of the second moving groove coincides with the cross-sectional projection of the third moving groove, and the moving cavity is formed among the first, second, and third moving grooves.

[0051] The sum of the lengths of the top shell 10102 and the cover plate 10103 is less than the length of the bottom shell 10101. In the case of inconsistent lengths, an L-shaped groove is formed between the bottom shell 10101 and the cover plate 10103. When cutting the rubber strip, the L-shaped groove is used to align with the auxiliary component 3. At this time, the edge part of the auxiliary component 3 fits against the inner side of the L-shaped groove, ensuring the smoothness and accuracy of the cutting process.

[0052] There are two rectangular holes 104, and the two rectangular holes 104 are respectively opened on the bottom shell 10101 and the top shell 10102. The two rectangular holes 104 cooperate with each other to form a fixing position for fixing the position of the rotating column 103, and the rotating column 103 is located inside the fixing position.

[0053] One end of the bottom shell 10101 close to the rectangular hole 104 is fixedly connected to the top shell 10102, the cover plate 10103 is installed at one end of the bottom shell 10101 away from the rectangular hole 104. An installation groove is opened inside the bottom shell 10101, and an installation block corresponding to the installation groove is fixedly provided on the cover plate 10103, and the installation block is located inside the installation groove.

[0054] The installation block is a trapezoidal structural member, and the end surface where the upper base of the trapezoidal structural member is located is fixedly connected to the cover plate 10103.

[0055] Such asFigure 10 As shown in the figure: An auxiliary cutting device for cutting rubber strips further includes: a pressing plate 4 for pressing the rubber strip. The pressing plate 4 is located inside the rubber strip, the outer side wall of the pressing plate 4 abuts against the inner side wall of the rubber strip, and the outer side wall of the rubber strip abuts against the inner side wall of the auxiliary component 3.

[0056] A plurality of the scales 301 are provided, and the plurality of scales 301 are respectively arranged at the edge part of the auxiliary component 3.

[0057] Working process:

[0058] When it is necessary to cut the damaged rubber strip on the cutting device, the auxiliary component 3 wraps the rubber strip, and checks whether the current cut is vertical according to the scale 301 located at the edge of the auxiliary component 3. By rotating the rotating column 103, the length of the cutter protruding is controlled. During the rotation of the rotating column 103, the moving block 102 provided with corresponding external threads is driven to move through the internal threads, thereby realizing the function of adjusting the length of the cutter protruding.

[0059] During the cutting process, the end of the cover plate 10103 is used to abut against the auxiliary component 3 for cutting.

[0060] Match the new rubber strip with the auxiliary component and the pressing plate, and use the scale at the edge part of the auxiliary component to correct the position of the rubber strip. Fill the inside of the rubber strip with the pressing plate and press the rubber strip against the inside of the auxiliary component, and fix it with a clamping tool. Ensure verticality and cut the rubber strip as required by the cutter to avoid waste of materials.

[0061] Bond the rubber strip to the machine body according to the process requirements, wrap and fix the rubber strip with the installation component, fix the installation component at the position to be connected with an auxiliary fixture, and wait for the bonding to be completed. The installation component ensures that the rubber strip will not deform during the process of waiting for the bonding result.
