Description

Technical Field

[0001] This utility model relates to the field of phase shifter manufacturing technology, and in particular to an aluminum material processing positioning fixture for phase shifter manufacturing. Background Technology

[0002] In high-end electronic devices such as microwave communication and radar systems, phase shifters are key passive devices whose performance directly affects the phase accuracy and signal stability of the entire system. Phase shifters are usually manufactured using high-precision, high-surface-quality aluminum alloy materials, which have advantages such as good conductivity, lightweight, easy processing and moderate cost.

[0003] In the precision machining process of aluminum components of phase shifters, such as CNC milling, drilling, and engraving, the performance of the workpiece positioning fixture is crucial. It directly determines the positioning accuracy of the machined parts, the consistency of repeated clamping, and the vibration resistance and stability during the machining process, ultimately affecting the dimensional tolerances, geometric tolerances, and surface quality of the phase shifter cavity or cover plate.

[0004] However, current aluminum machining positioning fixtures used in phase shifter manufacturing have the following shortcomings in practical use. Their structural design typically only clamps and positions a single workpiece or a group of workpieces. Operators need to frequently perform "clamping-machining-unclamping" cycles. After machining each workpiece, the machine must be stopped and the next workpiece re-clamped. A significant amount of time is wasted on repetitive auxiliary operations rather than effective cutting. This results in a very low output rate for a single machine, failing to meet the needs of large-scale production and becoming a major bottleneck for increasing capacity. Furthermore, the inefficient clamping method leads to a decrease in the effective utilization rate of the machine tool, limiting the number of products processed per unit time. This significantly reduces the machine tool, labor, and management costs allocated to each product, weakening the product's market competitiveness. Utility Model Content

[0005] Given that most existing positioning fixtures clamp and position single or group workpieces, operators need to frequently perform "clamping-machining-unclamping" cycles. After machining each workpiece, the machine must be stopped and the next workpiece re-clamped. A significant amount of time is wasted on repetitive auxiliary operations rather than effective cutting. This results in a very low output rate for a single machine, failing to meet the needs of large-scale production. Therefore, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an aluminum material processing positioning fixture for phase shifter manufacturing. Its purpose is to: by adopting a unique layout and linkage mechanism, it can simultaneously and accurately position and clamp four sets of aluminum workpieces. This allows the machine tool to complete the continuous processing of four workpieces after one clamping, distributing the clamping auxiliary time to four workpieces, significantly shortening the average clamping time of a single product, doubling the machine tool utilization rate, and achieving a revolutionary improvement in production efficiency.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an aluminum material processing positioning fixture for phase shifter manufacturing, including a base plate, a positioning platform disposed above the base plate, four sets of support columns disposed at both ends of the top of the base plate, wherein the top of the support columns and the bottom of the positioning platform are connected to each other, four sets of aluminum materials disposed at the top of the positioning platform, and four sets of connecting grooves disposed at both ends of the top of the positioning platform, wherein the connecting grooves penetrate the positioning platform.

The two sets of blocking blocks on the top of the two sets of limiting blocks are arranged alternately.

[0011] As a preferred embodiment of the aluminum material processing positioning fixture for phase shifter manufacturing described in this utility model, the top of the positioning platform is provided with three sets of slide rails, four sets of connecting grooves on the same side are respectively located between two sets of slide rails, four sets of aluminum materials are respectively located between the slide rails and the connecting grooves, and multiple sets of sliding blocks are provided on the inner side of the slide rails.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] 1. This utility model, through the setting of four sets of motors and electric push rods on the connecting base plate, enables the pressing plate to rotate and lift, and can simultaneously and accurately position and clamp four sets of aluminum workpieces. This allows the machine tool to complete the continuous processing of four workpieces after one clamping, distributing the clamping auxiliary time to four workpieces, significantly shortening the average clamping time of a single product, doubling the machine tool utilization rate, and achieving a revolutionary improvement in production efficiency. Furthermore, due to the increase in production efficiency, the output per unit time increases significantly, reducing the labor hours, energy consumption, and equipment depreciation costs consumed per unit product, effectively lowering the overall manufacturing cost of the product, and enhancing the company's profit margin and market competitiveness.

[0015] 2. This utility model can restrict four groups of aluminum materials from multiple angles by matching the blocking block, sliding block, limiting block and pressing plate. Since the aluminum materials are rigidly fixed in multiple directions, micro-vibration and displacement during processing are almost completely eliminated, which makes the aluminum materials more stable during subsequent processing.
