A machining tool

Abstract

This utility model relates to the field of composite material parts processing, and more particularly to a processing fixture. The processing fixture proposed in this utility model is used to process parts to be processed, and includes an auxiliary positioning component and a template processing mechanism. The auxiliary positioning component includes a horizontally arranged first positioning part, a transition part, and a vertically arranged second positioning part. By setting the auxiliary positioning component, the first positioning part of the auxiliary positioning component can press the first positioning component of the template processing mechanism against the horizontal plate part, and the second positioning part can abut against the vertical plate part, ensuring the structural fit between the auxiliary positioning component and the part to be processed, thereby firmly positioning the template processing mechanism on the part to be processed. Since the first positioning component is clamped between the first positioning part and the horizontal plate part, the movement trajectory of the template processing mechanism will not deviate, and the template processing mechanism will not vibrate up and down when moving, greatly improving processing accuracy and processing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of composite material parts processing, and in particular to a processing tooling. Background Technology

[0002] After molding, composite materials require machining or manual processing to achieve the final part state. However, due to the high hardness, high strength, poor thermal conductivity, and anisotropy of composite materials, defects such as delamination, tearing, burrs, stringing, and chipping are easily generated during processing, making them difficult-to-machine materials. Flanged panels are a common composite material part in aircraft, serving as structural support and pressure resistance. They are irregularly shaped parts made of fabric, with a relatively complex overall structure and high machining difficulty. Manual machining is complex and requires a long learning period, typically necessitating extensive training to master the process. Among these, die-cutting is the most complex.

[0003] When using a template to machine parts, the template is prone to vibration, leading to incomplete or over-cutting. Furthermore, the operator needs to press the template firmly with their thumb and forefinger during processing; prolonged operation causes muscle fatigue and soreness in this area, making continuous machining impossible. The complex structure of the part also makes the operation cumbersome, demanding a high level of skill and resulting in a high error rate, thus hindering efficient and convenient machining. Therefore, a solution to these problems is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a processing fixture to solve the problems of low processing efficiency and high processing difficulty of the parts to be processed in the prior art.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] A machining fixture is used to process a part to be processed. The part to be processed includes a vertically arranged vertical plate and a horizontally arranged horizontal plate, the horizontal plate being connected to the vertical plate. The machining fixture includes an auxiliary positioning component and a template processing mechanism. The auxiliary positioning component includes a horizontally arranged first positioning part, a transition part, and a vertically arranged second positioning part. The transition part is connected between the first positioning part and the second positioning part. The template processing mechanism includes a first positioning component and a processing component. The lower side of the first positioning component abuts against the upper side of the horizontal plate to position the template processing mechanism on the part to be processed. The processing component is capable of processing the horizontal plate. The lower side of the first positioning part presses against the upper side of the first positioning component to press the first positioning component against the upper side of the horizontal plate. The second positioning part can abut against the vertical plate.

[0007] Optionally, the first positioning part is plate-shaped, and the thickness direction of the first positioning part is parallel to the vertical direction.

[0008] Optionally, the second positioning part is plate-shaped, and the thickness direction of the second positioning part is parallel to the horizontal direction.

[0009] Optionally, the transition portion is strip-shaped and is connected between one end of the first positioning portion and one end of the second positioning portion.

[0010] Optionally, the auxiliary positioning component further includes a third positioning part, which is L-shaped and connected at one end to the second positioning part. The corner of the third positioning part can be engaged with the edge of the vertical plate.

[0011] Optionally, the auxiliary positioning component is made of stainless steel.

[0012] Optionally, the auxiliary positioning component is provided with a magnetic groove, and the processing fixture further includes a magnetic component, which is installed in the magnetic groove and can attract the auxiliary positioning component and the part to be processed.

[0013] Optionally, the first positioning element is disc-shaped with its thickness direction parallel to the vertical direction, and the processed part is cylindrical and coaxially connected to the lower side of the first positioning element.

[0016] The beneficial effects of this utility model are:

[0017] This utility model proposes a processing fixture for processing a part to be processed. The part to be processed includes a vertically arranged vertical plate and a horizontally arranged horizontal plate, which are connected to the vertical plate. The processing fixture includes an auxiliary positioning component and a template processing mechanism. The auxiliary positioning component includes a horizontally arranged first positioning part, a transition part, and a vertically arranged second positioning part. The transition part is connected between the first positioning part and the second positioning part. The template processing mechanism includes a first positioning component and a processing component. The lower side of the first positioning component abuts against the upper side of the horizontal plate to position the template processing mechanism on the part to be processed. The processing component can process the horizontal plate. The lower side of the first positioning part presses against the upper side of the first positioning component to press the first positioning component against the upper side of the horizontal plate. The second positioning part can abut against the vertical plate. By setting auxiliary positioning components, the first positioning part of the auxiliary positioning component can press the first positioning component of the template processing mechanism against the horizontal plate part, while the second positioning part can abut against the vertical plate part, ensuring the fit between the auxiliary positioning component and the part to be processed. This securely positions the template processing mechanism on the part to be processed, facilitating the grinding of the horizontal plate part. When it is necessary to move the processing position, the template processing mechanism can be moved directly. Since the first positioning component is clamped between the first positioning part and the horizontal plate part, the movement trajectory of the template processing mechanism will not deviate, and the template processing mechanism will not vibrate up and down when moving. The processing operation can be completed accurately and efficiently without the operator constantly pressing the template processing mechanism, greatly improving the processing accuracy and efficiency.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] This embodiment proposes a machining fixture to solve the problems of low machining efficiency and high machining difficulty of the parts to be processed in the prior art.

[0036] like Figures 1-6 As shown, the machining fixture is used to process the part 100 to be processed. The part 100 to be processed includes a vertically arranged vertical plate portion 102 and a horizontally arranged horizontal plate portion 101. The horizontal plate portion 101 is connected to the vertical plate portion 102. The machining fixture includes an auxiliary positioning component 1 and a template processing mechanism 2. The auxiliary positioning component 1 includes a horizontally arranged first positioning portion 11, a transition portion 14, and a vertically arranged second positioning portion 12. The transition portion 14 is connected between the first positioning portion 11 and the second positioning portion 12. The template processing mechanism 2 includes a first positioning component 21 and a processing component 22. The lower side of the first positioning component 21 abuts against the upper side of the horizontal plate portion 101 so that the template processing mechanism 2 is positioned on the part 100 to be processed. The processing component 22 can process the horizontal plate portion 101. The lower side of the first positioning portion 11 presses against the upper side of the first positioning component 21 so that the first positioning component 21 is pressed against the upper side of the horizontal plate portion 101. The second positioning portion 12 can abut against the vertical plate portion 102.

[0037] Understandably, the part to be processed 100 includes a vertical plate portion 102 and a horizontal plate portion 101. When processing the part to be processed 100, the horizontal plate portion 101 is generally ground or trimmed to meet the standards for qualified products. However, in the prior art, when processing the horizontal plate portion 101, the operator often needs to use their thumb and forefinger to press the mold sleeve firmly to accurately position it on the part to be processed 100, or to prevent it from vibrating, in order to ensure the accuracy of processing. This operation is cumbersome and can easily cause operator fatigue, resulting in low processing efficiency and high processing difficulty. In this embodiment, by setting an auxiliary positioning component 1, the first positioning part 11 of the auxiliary positioning component 1 can press the first positioning part 21 of the template processing mechanism 2 against the horizontal plate part 101, while the second positioning part 12 can abut against the vertical plate part 102, ensuring the fit between the auxiliary positioning component 1 and the part to be processed 100, thereby stably positioning the template processing mechanism 2 on the part to be processed 100, which facilitates the processing part 22 to grind the horizontal plate part 101. When it is necessary to move the processing position, the template processing mechanism 2 can be directly pushed to move. Since the first positioning part 21 is clamped between the first positioning part 11 and the horizontal plate part 101, the movement trajectory of the template processing mechanism 2 will not be deviated, and the template processing mechanism 2 will not shake up and down when it moves. The processing operation can be completed accurately and efficiently without the operator having to press the template processing mechanism 2 tightly at all times, which greatly improves the processing accuracy and processing efficiency.

[0038] like Figures 1-3 As shown, optionally, the first positioning part 11 is plate-shaped, and the thickness direction of the first positioning part 11 is parallel to the vertical direction. This arrangement reduces the weight of the first positioning part 11 and improves the portability of the auxiliary positioning member 1. At the same time, this arrangement increases the contact area between the first positioning part 11 and the first positioning member 21, increases the positioning stability of the template processing mechanism 2, and thus improves the reliability of the processing tooling.

[0039] Optionally, the second positioning part 12 is plate-shaped, and the thickness direction of the second positioning part 12 is parallel to the horizontal direction. This arrangement also reduces the weight of the second positioning part 12 and improves the portability of the auxiliary positioning member 1. At the same time, this arrangement increases the contact area between the second positioning part 12 and the vertical plate part 102, increases the fit and positioning stability between the auxiliary positioning member 1 and the workpiece 100 to be processed, and thus improves the reliability of the processing tooling.

[0040] Optionally, the transition portion 14 is strip-shaped and connects one end of the first positioning portion 11 and one end of the second positioning portion 12. By providing the transition portion 14, the first positioning portion 11 and the second positioning portion 12 can be connected, improving the structural rationality of the auxiliary positioning member 1. At the same time, the strip-shaped transition portion 14 can significantly reduce the weight of the auxiliary positioning member 1, improving its portability. Furthermore, the status of the part to be processed 100 can be observed at any time through the gaps on both sides of the strip-shaped transition portion 14, ensuring that the part to be processed 100 is in a normal shape.

[0041] Optionally, the auxiliary positioning component 1 further includes a third positioning part 13, which is L-shaped and connected at one end to the second positioning part 12. The corner of the third positioning part 13 can be engaged with the edge of the vertical plate part 102. This arrangement further enhances the fit between the auxiliary positioning component 1 and the workpiece 100, thereby improving positioning stability and ensuring the processing accuracy of the template processing mechanism 2.

[0042] For example, one end of the first positioning part 11 is connected to one end of the transition part 14, the top end of the second positioning part 12 is connected to the other end of the transition part 14, and the third positioning part 13 is connected to the waist of the second positioning part 12. Since the first positioning part 11 is located above the workpiece 100 to be processed and the second positioning part 12 is located to the side of the workpiece 100 to be processed, when the third positioning part 13 is located at the waist of the second positioning part 12, it can avoid interference between itself and the lower side of the workpiece 100 to be processed, thereby avoiding unevenness at the bottom of the workpiece 100 to be processed and affecting the processing accuracy.

[0043] Optionally, the auxiliary positioning component 1 is made of stainless steel. This design enhances the strength of the auxiliary positioning component 1, thereby increasing its service life and improving the reliability of the machining tooling. Of course, in other embodiments, the auxiliary positioning component 1 can also be made of other metal components, and the choice can be made as needed according to the application scenario; no further restrictions are imposed here.

[0044] Optionally, the auxiliary positioning component 1 is provided with a magnetic groove, and the machining fixture also includes a magnetic suction component installed in the magnetic groove. The magnetic suction component can attract the auxiliary positioning component 1 and the part 100 to be processed. This setting strengthens the fit between the auxiliary positioning component 1 and the part 100 to be processed by the magnetic suction component, thereby preventing the template machining mechanism 2 from shifting and ensuring machining accuracy and stability.

[0045] It should be noted that in some embodiments, magnetic components may not be used to fix the workpiece 100 and the auxiliary positioning component 1. Instead, C-clamps may be used to hold the workpiece 100 and the auxiliary positioning component 1 together, or fasteners such as double-sided tape, bolts, or pins may be used to fix the two together. However, fixing methods such as C-clamps, double-sided tape, bolts, or pins require special disassembly and assembly by workers, resulting in low efficiency. In addition, double-sided tape is prone to leaving adhesive residue. Its convenience and user experience are not as good as using magnetic components directly. However, it can be selected as needed based on the available tools on site.

[0046] For example, the magnetic attractor is a neodymium iron boron magnet. Neodymium iron boron magnets are strong magnetic materials, which can enhance the magnetic attraction strength of the magnetic attractor, thereby improving the fit between the auxiliary positioning component 1 and the part 100 to be processed. Of course, in other embodiments, the magnetic attractor can also be other strong magnetic materials; the choice can be made according to actual needs, and no further restrictions are imposed here.

[0047] Alternatively, the magnetic suction component may not be placed in the magnetic suction groove, but may be directly attached to the part to be processed 100, ensuring that both the part to be processed 100 and the auxiliary positioning component 1 are simultaneously attracted. This arrangement allows the position of the magnetic suction component to be changed at any time to avoid interference when it interferes with other workpieces, and is not limited to being placed in the magnetic suction groove, thereby ensuring the smoothness of the processing and improving the user experience.

[0048] like Figures 4-6 As shown, optionally, the first positioning member 21 is disc-shaped with its thickness direction parallel to the vertical direction, and the machining part 22 is cylindrical and coaxially connected to the lower side of the first positioning member 21. This arrangement makes the shape of the first positioning member 21 smoother, thereby reducing the difficulty of moving between the horizontal plate part 101 and the first positioning part 11, and improving the structural rationality of the machining fixture.

[0049] Optionally, the template processing mechanism 2 includes a processing mechanism body, on which the first positioning member 21 and the processing member 22 are both mounted. This configuration provides mounting positions for the first positioning member 21 and the processing member 22, improving the structural rationality of the template processing mechanism 2.

[0050] Optionally, the first positioning member 21 is rotatably mounted on the processing mechanism body. When the first positioning member 21 moves between the horizontal plate portion 101 and the first positioning portion 11, the first positioning member 21 can rotate, thereby reducing friction and improving the smoothness of movement of the template processing mechanism 2.

[0051] For example, the processing mechanism body includes a driving member 23 and a connecting member 24. A first positioning member 21 is installed below the driving member 23. The driving member 23 is connected to the processing member 22 in a transmission manner. The connecting member 24 is disc-shaped and coaxially connected between the first positioning member 21 and the processing member 22. This arrangement drives the processing member 22 to rotate through the driving member 23, thereby performing processing operations on the workpiece 100 to be processed. The connecting member 24 separates the first positioning member 21 and the processing member 22 to avoid interference between them. Furthermore, the connecting member 24 has a smooth surface, which improves the smoothness of movement of the template processing mechanism 2 when it abuts against the workpiece 100 to be processed.

[0052] For example, the machining part 22 is a grinding wheel. This arrangement enables the machining part 22 to perform fine grinding on the horizontal plate portion 101, thereby achieving the finished product standard and improving the structural rationality of the machining tooling. Of course, in other embodiments, the machining part 22 can also be a component such as a circular cutting tool, and can be selected as needed according to the machining requirements, without too many restrictions here.

[0053] The working process of the machining tooling in this embodiment is as follows:

[0054] First, install the magnetic connector into the magnetic slot.

[0055] Next, the second positioning part 12 of the auxiliary positioning member 1 is abutted against the vertical plate part 102 of the part to be processed 100, and the first positioning part 11 is spaced apart from the horizontal plate part 101 by a preset distance (the preset distance can be set as needed according to the thickness of the first positioning member 21, and is not specifically limited in this embodiment), and the third positioning part 13 is snapped onto the edge of the vertical plate part 102.

[0056] Finally, the first positioning member 21 of the template processing mechanism 2 is brought into contact with the horizontal plate portion 101, and the first positioning part 11 presses the first positioning member 21 against the horizontal plate portion 101. The template processing mechanism 2 is then activated to process the remaining three sides of the horizontal plate portion 101 on which the auxiliary positioning member 1 is installed.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
