Description

Technical Field

[0001] The present invention belongs to the technical field of multi-centered core body processing, and relates to a processing method for the structure of a multi-centered core body of military supplies. Background Art

[0002] When traditional processing techniques are applied to multi-centered structural parts, many insurmountable problems are exposed. On the one hand, the process arrangement lacks systematicness and scientificity. In the early processing flow, rough machining and finish machining are often simply separated, without fully considering the special precision requirements of multi-centered structural parts. As a result, due to the frequent conversion and instability of the positioning reference between different processing stages, it is extremely easy to cause deviation in the center position. For example, in some traditional processes, the overall outer shape is first rough machined, and then the parts where each center is located are finely machined separately. During this period, multiple clamping and positioning adjustments are carried out, resulting in an increasing cumulative error and making it difficult to ensure the precise correspondence of multiple center positions.

[0003] On the other hand, the lag in positioning and detection means severely restricts the improvement of processing precision. Traditional positioning methods mostly rely on simple fixtures and manual alignment, and their positioning accuracy can usually only reach the millimeter level, far from meeting the requirements of multi-centered structural parts for micron or even sub-micron level precision. In the detection link, conventional measuring tools such as calipers and micrometers not only have low measurement efficiency, but also are difficult to achieve comprehensive and precise measurement for complex multi-centered position relationships and perpendicularity detection. This makes it difficult to detect and correct position deviation or perpendicularity out-of-tolerance problems in a timely manner during the processing, and a large number of unqualified products flow into the subsequent processes, resulting in serious waste of resources and increased costs. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] S3: Fine processing, realizing the fine processing of the core body part through a numerical control lathe and CNC processing equipment, and further improving the outer circle surface quality and dimensional accuracy of the core body part;

[0018] As a further solution of the present invention: Before step S5: Anodizing treatment and S6: Conductive anodizing treatment, cleaning processing is required.

[0019] As a further solution of the present invention: After completing step S4: Multi-center machining, targeted detection of the center positions of the core components is required.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In the embodiments of the present invention, a processing method for a multi-centered core structure of military supplies is used for the processing of the multi-centered core structure; as Figure 1 shown, the multi-centered core structure includes: a substrate at the bottom, and two sets of mounting plates extending upward are formed on the mounting plate; a substrate center hole is provided at the center position of the substrate, and mounting holes located on the same axis are respectively provided on the two sets of mounting plates; the processing purpose of this method is to realize the processing of the multi-centered core structure while ensuring that the two center positions of the core parts correspond, and the line connecting the two center positions is perpendicular to the core center line (the axis line of the substrate center hole) and meets the tolerance requirements;

[0028] This method includes the following steps:

[0029] S1: Forming processing, the outer shape of the core part is processed by a numerical control lathe and CNC processing equipment to reserve appropriate allowances for subsequent fine processing, ensure uniform processing allowances, and is conducive to improving subsequent processing accuracy;

[0030] S2: Aging treatment, the core part is put into an aging furnace for treatment and then the dimensional stability is inspected. The aging treatment determines the temperature and time according to the material of the core part, effectively eliminates the internal stress during processing, and through subsequent hardness testing and key dimension measurement, ensures the dimensional stability of the part during subsequent processing and use, and improves the product quality stability;

[0031] S3: Fine processing, the core part is finely processed by a numerical control lathe and CNC processing equipment to further improve the outer circle surface quality and dimensional accuracy of the core part, and provide a processing basis for subsequent processing;

[0032] S4: Multi-centered processing, through the CNC processing equipment cooperating with a flipping jig with a flipping function, the multi-centered processing of the core part is realized in one clamping operation, ensuring that the two center positions of the core part correspond, and the line connecting the two center positions is perpendicular to the core center line and meets the tolerance requirements;

[0033] S5: Anodic oxidation treatment, the processed part after finishing is anodized by an anodic oxidation equipment to form an oxide film layer on the surface of the part to improve the corrosion resistance, wear resistance and surface hardness of the part;

[0034] S6: Conductive oxidation treatment. The parts after anodic treatment are subjected to conductive oxidation treatment in a conductive oxidation manner to form a conductive oxide film layer on the surface of the parts, so as to improve the conductivity and corrosion resistance of the parts.

[0035] S7: Discharging and packaging: Package and discharge the processed products to complete all processing work.

[0036] Furthermore, as Figure 2 shown in step S4: Multi-center machining, the flipping fixture includes: a fixture base installed on the CNC machining table; two sets of oppositely arranged clamping and moving modules are provided on the fixture base, and a clamping group is installed on the clamping and moving modules;

[0037] The clamping group includes: a clamping frame installed on the clamping and moving module, a clamping seat for clamping the workpiece is installed on the clamping frame, and a flipping module for realizing the flipping work of the clamping seat; during clamping installation, the workpiece is clamped by the clamping seats on both sides of the clamping group, and during the processing, the workpiece is driven by the flipping module to perform flipping work at any angle, so that the CNC machining machine tool can realize multi-center machining of the core parts in one clamping operation, ensure that the two center positions of the core parts correspond, and the connection line of the two center positions is perpendicular to the core center line and meets the tolerance requirements.

[0038] And after completing step S4: Multi-center machining, it is necessary to conduct targeted detection on the center positions of the core parts. A coordinate measuring machine is used to measure the key dimensions and position accuracies of the core parts, focusing on detecting the coordinates of the two center positions, the perpendicularity of the center connection line to the core center line, and the dimensions of each hole diameter and shaft diameter, etc., and mark the unqualified products in time.

[0039] Furthermore, after step S1: Forming machining and step S3: Precision machining, a benchwork processing step is also required to perform processing work such as deburring and chamfering the sharp edges on the surface of the parts to improve the surface quality and safety of the parts.

[0040] Furthermore, after step S2: Aging treatment, S3: Precision machining, S4: Anodic oxidation treatment, and S5: Conductive oxidation treatment, corresponding inspection processing steps are required;

[0041] Among them, the inspection processing for step S2: Aging treatment and S3: Precision machining is the detection of the dimensional accuracy, shape accuracy, and surface quality of the parts to ensure that the external structure dimensions of the parts meet the processing requirements;

[0042] And the inspection processing after step S4: Anodic oxidation treatment and S5: Conductive oxidation treatment is the detection of the film layer and the film layer performance to ensure that the structural performance of the parts meets the processing requirements.

[0043] Further, during the process from step S5: Conductive Oxidation Treatment to step S5: Conductive Oxidation Treatment, it is possible to select to add CNC machine tool processing steps and benchwork processing steps for the parts according to the inspection results or the actual requirements of the part products, so as to meet the special processing requirements of some part products.

[0044] Preferably, before the processing of step S5: Anodic Oxidation Treatment and step S6: Conductive Oxidation Treatment, cleaning processing needs to be carried out. When cleaning, a suitable cleaning agent is used to clean the parts to remove oil stains, impurities, etc. on the surface of the parts, so as to prepare for the surface treatment process.
