Description

Technical Field

[0001] This utility model relates to the field of profile hole processing technology, and in particular to a general-purpose profile hole auxiliary processing device. Background Technology

[0002] Figure 1 For L-shaped profiles, the traditional process involves manual marking by a fitter, followed by clamping the part for positioning and drilling. However, due to the complex hole structure and high dimensional accuracy requirements of these parts (complex hole structure refers to the presence of numerous holes on a plane with inter-angle and inter-distance relationships requiring precision), fitters are prone to marking errors during operation, resulting in low processing efficiency. The hole positioning surface of the profile is also prone to deformation, affecting the fitter's marking and making it difficult to guarantee the dimensional accuracy of the machined holes. To address these issues, this utility model provides an auxiliary processing device. Utility Model Content

[0003] The purpose of this invention is to provide a general-purpose auxiliary processing device for profile hole positions.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A general-purpose profile hole auxiliary processing device includes a base plate, a positioning plate, and a pressure plate. The base plate has a plurality of positioning holes and a plurality of threaded holes. The positioning holes are arranged in a straight line, and the threaded holes are also arranged in a straight line, with the lines formed by the two being parallel to each other. Positioning pins are inserted into the positioning holes. The insertion position of the positioning pins needs to be selected according to the size and specifications of the part to be processed. The positioning plate is positioned by the positioning pins and clamps the part to be processed on the base plate. Bolts pass through the through holes on the pressure plate and engage with the threaded holes on the base plate to fix the part to be processed and the positioning plate on the base plate. Then, the part to be processed is processed by a drilling machine or other processing tools.

[0006] Furthermore, the pressure plate has an L-shaped structure. One end of the L-shaped pressure plate is pressed onto the part to be processed, and the other end of the pressure plate is inserted into the positioning groove. Through the structural design of the pressure plate and the positioning groove, the pressure plate and the positioning pressure plate can be fixed with only one bolt, which facilitates the disassembly and replacement of the part to be processed and improves production efficiency.

[0007] Furthermore, the base plate is provided with a material discharge groove, which is located below the machining hole of the clamped and fixed part to be processed. The part to be processed may have two folded surfaces that both need to be machined. The material discharge groove can avoid direct contact between the base plate and the machining tool, and also facilitates the discharge of waste generated during the processing.

[0008] Furthermore, the bolts are internal hex bolts, which are convenient to use with a hexagonal L-shaped wrench for fixing or loosening.

[0009] In summary, this utility model has the following beneficial effects:

[0010] 1. Positioning and locking ensures accuracy: The machining parts, positioning pressure plate and base plate are firmly locked by positioning pins, which effectively prevents the parts from shifting during the machining process, thereby improving the machining accuracy;

[0011] 2. Improved efficiency with single installation: Hole machining can be completed with only one installation, avoiding multiple clamping of parts, reducing installation errors caused by multiple clamping, and thus improving machining accuracy and efficiency;

[0012] 3. Cost reduction through universal tooling: This tooling is universal; only the positioning plate needs to be replaced to perform hole processing on the same type of material, which helps to save on processing tooling costs. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0017] like Figure 2As shown, a general-purpose profile hole auxiliary processing device includes a base plate 1, a positioning pressure plate 3, and a pressure plate 5. The base plate 1 is provided with a plurality of positioning holes and a plurality of threaded holes 7. The positioning holes are arranged in a straight line, and the threaded holes 7 are also arranged in a straight line, and the straight lines formed by the two are parallel to each other. Positioning pins 6 are inserted into the positioning holes. The insertion position of the positioning pins 6 needs to be selected according to the size specifications of the part to be processed 2. The positioning pressure plate 3 is positioned by the positioning pins 6 and clamps the part to be processed 2 onto the base plate 1. Bolts 4 pass through the through holes on the pressure plate 5 and cooperate with the threaded holes 7 on the base plate 1 to fix the part to be processed 2 and the positioning pressure plate 3 onto the base plate 1. Then, the part to be processed is processed by a drilling machine or other processing tools.

[0018] Furthermore, the pressure plate 5 has an L-shaped structure. One end of the L-shaped pressure plate 5 is pressed onto the part 2 to be processed, and the other end of the pressure plate 5 is inserted into the positioning groove 8. Through the structural design of the pressure plate 5 and the positioning groove 8, the pressure plate 5 and the positioning pressure plate 3 can be fixed with only one bolt 4, which facilitates the disassembly and replacement of the part 2 to be processed and improves production efficiency.

[0019] Furthermore, the base plate 1 is provided with a material discharge groove 9, which is located below the machining hole of the clamped and fixed workpiece 2. The workpiece 2 may have two folded surfaces that need to be machined. The material discharge groove 9 can avoid direct contact between the base plate 1 and the machining tool, and also facilitates the discharge of waste generated during the machining process.

[0020] Furthermore, the bolt 4 is an internal hex bolt, which is convenient to use with a hexagonal L-shaped wrench for fixing or loosening.

[0021] Working principle: When using this fixture to process the holes in part 2, firstly, select a positioning plate 3 that matches the holes in part 2. Then, precisely adjust the position of positioning pin 6 according to the specific length of part 2. Next, place part 2 on the fixture and ensure it fits tightly. Then, using plate 5 and bolts 4, align the corresponding threaded holes on the plate and tighten the bolts to lock the plate, thus ensuring that the profile will not shift during processing. Then, proceed with processing part 2.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
