Description

Technical Field

[0001] This application relates to the technical field of filter processing equipment, and in particular to a filter positioning and processing fixture. Background Technology

[0002] In the field of electronic component manufacturing, filters, as core components of signal processing, are directly affected by their positioning accuracy, which impacts processing quality and performance stability. Traditional filter manufacturing processes often employ fixed fixtures for positioning. Early filter manufacturing fixtures were mostly fixed structures designed for single-model filters, using mechanical slots or bolt locking methods for fixation.

[0003] Regarding the aforementioned technologies, it has been found that most existing filter processing fixtures clamp the product directly from the outside. This not only easily damages the product surface but also requires constantly changing clamping positions to achieve comprehensive processing, thus reducing processing efficiency. Furthermore, traditional fixtures have poor versatility; in scenarios involving multi-variety, small-batch production, frequent fixture changes are necessary, leading to extended equipment downtime and severely impacting production efficiency.

[0004] In addition, the fixed fixture has poor adaptability to the shape of the filter. For filters with curved or irregular shells, traditional flat slots cannot achieve a tight fit, and are prone to shaking during positioning, resulting in dimensional deviations during processing and affecting the stability of processing. Utility Model Content

[0005] To achieve flexible clamping and reduce the frequency of fixture changes, this application provides a filter positioning machining fixture.

[0006] The filter positioning and machining fixture provided in this application adopts the following technical solution:

[0007] A filter positioning and processing fixture includes a machine table. Movable frames are mounted on both sides of the upper surface of the machine table and are slidably connected to the machine table. An electric cylinder is fixedly mounted on the machine table to drive the movable frames to move. Two sets of angle rods are mounted on the movable frames. The middle part of the angle rods is rotatably connected to the movable frames. A driving component for adjusting the included angle of the two sets of angle rods is mounted at the head of the movable frames. The driving component is slidably connected to the movable frames. An electric cylinder for adjusting the lifting and lowering of the driving component is fixedly mounted in the movable frames. Support seats are rotatably mounted at both ends of the angle rods.

[0008] By adopting the above technical solution, and by setting sliding movable frames on both sides of the equipment table, and using an electric cylinder to drive the movable frames to move, the position of the movable frames can be flexibly adjusted according to the size of the filter, improving the adaptability of the fixture to filters of different sizes. Two sets of angle rods installed on the movable frames, through the cooperation of the drive unit and the electric cylinder, can adjust the included angle of the two sets of angle rods, thereby changing the position of the support base and further achieving precise positioning of the filter. This design makes the fixture positioning more flexible and can adapt to filters of different shapes. This allows for internal positioning and clamping of the filter during processing, facilitating better external processing of the filter, making operation more convenient, eliminating the need for multiple clamping operations, and effectively improving processing efficiency.

The guide slider and the base are integrally molded, which enhances the strength and stability of the structure, reduces the swaying of the movable frame during movement, and improves positioning accuracy.

[0013] Optionally, the angle rod includes a turntable base and an extension rod for rotatably mounting the support base. The extension rod is symmetrically mounted on both sides of the turntable base and is integrally formed with the turntable base.

[0014] By adopting the above technical solution, the angle rod uses a turntable base and an extension rod structure. The extension rod is symmetrically installed on both sides of the turntable base and is integrally formed, ensuring the structural strength and stability of the angle rod. This structural design makes the angle rod rotate more smoothly, allowing for accurate adjustment of the support position and precise positioning of the filter.

[0015] Optionally, a central shaft is provided on one side of the upright plate base for the turntable base to be rotatably mounted, and the central shaft is fixedly connected to the upright plate base.

[0016] By adopting the above technical solution, the central axis on the upright plate provides rotational support for the turntable base, allowing the angle rod to rotate flexibly around the central axis. The central axis is fixedly connected to the upright plate, ensuring the stability and reliability of the rotation and guaranteeing the accuracy of angle adjustment.

[0017] Optionally, the driving component includes a trapezoidal block and a vertical slide rod, wherein the vertical slide rod is fixedly installed on the lower end face of the trapezoidal block and slidably installed on the upright plate base.

The vertical slide rod is slidably mounted on the upright plate, allowing the driving component to rise and fall smoothly on the upright plate. This structural design ensures the accuracy and stability of the driving component's adjustment of the angle rod's included angle, and improves the positioning accuracy of the fixture.

[0019] Optionally, magnetic suction plates with suction extension rods are provided on both sides of the trapezoidal block, and the magnetic suction plates are fixedly connected to the trapezoidal block.

[0020] By adopting the above technical solution, the magnetic plates on both sides of the trapezoidal block can attract the extension rod. During the adjustment of the angle of the angle rod, the magnetic plates can enhance the connection stability between the drive component and the angle rod, prevent the angle rod from shaking or shifting during the adjustment process, and further improve the positioning accuracy and stability of the fixture.

[0021] Optionally, the support includes a base plate and a connecting lug plate, the connecting lug plate being fixedly installed on one side of the base plate and rotatably connected to the head of the extension rod.
