Description

Technical Field

[0001] The utility model belongs to the field of cutting equipment, in particular to a novel composite material cable fairing edge cutting process equipment. Background Art

[0002] The composite cable fairing is a strip-shaped shell product with an isosceles trapezoidal cross section. During the production process, the redundant side edges on both sides of the cable fairing need to be cut.

[0003] Because the process is relatively simple, the trimming operation was previously done manually, but this processing method has the following defects:

[0004] 1. Manually operated cutting machines have great safety hazards in cutting the edges of cable fairings. The large amount of dust and noise generated by cutting endangers the health of the operator. If the operation is improper, the cutter may easily cause mechanical damage to the operator.

[0005] 2. If the cable fairings are mass-produced, manual cutting will make the cutting process of the cable fairings non-standard, which is not conducive to large-scale orderly production, and it is impossible to form a unified processing standard. At the same time, the labor intensity of the operator is increased and the work efficiency is reduced;

[0006] 3. Because each operator cuts in a different way, cutting too fast or too slow will affect the cable fairing, and the quality of the product cannot be guaranteed, and the consistency of each product cannot be guaranteed. Utility Model Content

[0007] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a new composite cable fairing trimming process equipment, which can be suitable for large-scale production, automated processing to reduce personnel accompanying the machine and personnel injuries, standardize the trimming process standards, and ensure the consistency of the cut products.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is: developing a new composite cable fairing trimming process equipment, including a frame and a cutting machine and a clamp arranged on the frame;

[0009] The clamp is used to lift the outer shell of the cable fairing so that the redundant side edges of the cable fairing are supported on the eaves extending outwards on both sides of the clamp;

[0010] The cutting machine can move along three axes on one side of the clamp through a linkage mechanism. The cutter of the cutting machine is used to cut the side of the cable fairing on the same side. Multiple groups of clamping mechanisms are arranged on the other side of the clamp, including a positioning rod that applies downward pressure and an upper pressing part hinged on the end of the positioning rod. The upper pressing part is embedded in the inner wall of the cable fairing shell to fix the cable fairing in sections.

[0011] Furthermore, the clamping mechanism includes a lower positioning portion for limiting the initial position of the positioning rod and an upper positioning portion for applying downward pressure, and the initial position matches the depth of downward pressure required for the upper pressing portion to be embedded in the inner wall of the cable fairing shell.

[0012] Furthermore, the clamping mechanism includes a support column and a guide column, the lower positioning portion is connected to the support column, the other end of the positioning rod is sleeved on the upper end of the support column, the upper end of the guide column passes through the positioning rod, and the upper positioning portion is connected to the upper end of the guide column.

[0013] Furthermore, a mounting platform is provided on the frame, and the clamp and the clamping mechanism can be detachably connected to the mounting platform.

[0014] Furthermore, a plurality of plug-in slots are equidistantly arranged on the mounting platform, the lower ends of the guide columns slide in the corresponding plug-in slots, and the support columns are detachably connected to the outer side of the mounting platform.

[0015] Furthermore, the linkage mechanism includes a moving base sliding left and right along the z-axis, a propulsion plate on the moving base propelling forward and backward along the x-axis, and a lifting plate on the propulsion plate lifting up and down along the y-axis, and the cutting machine is connected to the lifting plate.

[0016] Furthermore, accordion covers are respectively arranged between the left and right sides of the movable base and the head and tail end points of the z-axis moving path, between the front and rear sides of the pushing plate and the head and tail end points of the x-axis moving path, and between the upper and lower sides of the lifting plate and the head and tail end points of the y-axis moving path.

[0017] Furthermore, a lower pressing portion is provided at a position of the inner wall of the clamp corresponding to the upper pressing portion.

[0018] Furthermore, a suction nozzle is provided on one side of the cutter in the cutting machine to absorb the debris generated by cutting.

[0019] Furthermore, the cut surfaces on both sides of the upper pressing portion match the inclinations of the inner walls on both sides of the cable fairing shell.

[0020] The advantages and positive effects of the utility model are:

[0021] 1. With the above technical solution, the overall structure of the tooling is compact, and the space in the workshop can be used reasonably. The cutting machine can achieve three-axis uniform speed movement through the linkage mechanism, which can be applied to different cutting requirements. The PLC controller can be linked with the linkage mechanism to control the movement path of the cutting machine along the x, y, and z axes to achieve automated processing and ensure the consistency of cutting quality, which is suitable for large-scale production.

[0022] 2. The accordion covers set along the moving paths of the x, y and z axes can protect the lead screw and guide rails to prevent the cutting debris and dust from accidentally entering, which will reduce the service life and operating accuracy. The suction nozzle set on one side of the cutting machine cutter can absorb the debris generated during cutting in real time, thereby improving the quality of the workshop environment.

[0023] 3. The setting of the clamp and the clamping mechanism enables the cable fairing to be fixed to prevent errors caused by deviation during cutting. The clamping mechanism is engaged with the inner wall of the cable fairing shell through the upper pressing part pressed down to avoid clamping marks and ensure the appearance of the product. The clamp and the clamping mechanism can be detachably connected to the mounting table and can be replaced according to cable fairings of different specifications to improve its applicability.
