Description

Technical Field

[0001] This invention relates to a tooling fixture, specifically a positioning fixture used in filter production. Background Technology

[0002] Currently, filters generally include a housing, filter element, check valve, bypass valve, etc. The filter element, also known as the filter element assembly, consists of filter paper, end caps (including upper and lower end caps), and a central tube. The filter paper and end caps need to be glued together after assembly, and the housing needs to be marked with inkjet printing. Both the housing and the filter element are round finished products, which require multi-point center assembly and positioning. Currently, this is done manually at multiple points, making it difficult to simultaneously and uniformly position the center. This results in many problems such as slow adjustment and center position deviation, which negatively impacts the accuracy of subsequent processing such as inkjet printing and glue application, and the product quality cannot be effectively guaranteed. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a quick center positioning fixture that can simultaneously, uniformly and quickly position the center of a circular finished product.

[0004] The objective of this invention is achieved through the following technical solution: a quick-release center positioning fixture, comprising a rotating disk, a positioning seat mounted on the rotating disk, a plurality of positioning blocks mounted on the positioning seat, the rotating disk and the positioning seat being connected to a rotational power source via the same central axis, a plurality of adjustable grooves being provided on the rotating disk and around the same central axis, and nuts that engage with the adjustable grooves being installed in the positioning blocks.

[0005] Positioning blocks are mounted on the positioning seat via positioning grooves. The positioning seat has a "Y"-shaped structure. There are three positioning blocks, each corresponding to a different position on the positioning seat. There are three nuts, three positioning grooves, and three adjusting grooves. The positioning grooves are straight grooves, and the adjusting grooves are arc-shaped grooves.

[0006] By adopting the technical solution of this invention, the three nuts within the positioning blocks simultaneously move towards the center of the rotating disk along the three adjusting grooves on the rotating disk. The three positioning blocks simultaneously and quickly clamp and position the circular filter paper in three different directions on the positioning grooves, laying a good foundation for subsequent processing. This invention utilizes the "three-point circle positioning" principle, effectively ensuring concentric, accurate, and rapid positioning of circular finished products. It has strong versatility, enabling concentric positioning of circular products of different specifications, effectively guaranteeing the processing quality of filters and their filter element assemblies.

[0009] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0010] like Figure 1 , Figure 2 As shown, the present invention relates to a quick-release center positioning fixture for filter production, comprising a rotating disk 1, a positioning seat 2 mounted on the rotating disk 1, and a plurality of positioning blocks 3 mounted on the positioning seat 2. The rotating disk 1 and the positioning seat 2 are connected to a rotational power source (which may be a rotary motor) through the same central shaft 11 (mounted on a concentric hole 13 of the rotating disk). A plurality of adjustable grooves 12 are provided on the rotating disk 1 and around the same central shaft. Nuts 4 that mate with the adjustable grooves are installed in the positioning blocks 3.

[0011] The same central shaft 11 is mounted on the concentric hole 13 of the rotating disk 1. Positioning blocks 3 are mounted on the positioning seat 2 via positioning grooves 5. The positioning seat 2 has a "Y"-shaped structure (the included angle between adjacent lines formed by its three different directions is 120 degrees). There are three positioning blocks 3, each corresponding to a different position on the positioning seat. There are three nuts 4, three positioning grooves 5, and three adjusting grooves 12. The positioning grooves 5 are straight grooves (with the same length and width), and the adjusting grooves 12 are arc-shaped grooves (both with the same arc).

[0012] When using this invention, first loosen the nut 4 inside the positioning block 3, place the round (cylindrical) filter paper on the center position of the positioning seat 2 (corresponding to the rotating disk 1), hold the positioning seat 2 with one hand, and manually rotate the rotating disk with the other hand (keeping the positioning seat fixed). The three nuts 4 inside the positioning block 3 simultaneously move towards the center of the rotating disk along the three adjusting grooves 12 on the rotating disk. The three positioning blocks clamp and position the round filter paper simultaneously and quickly in three different directions on the positioning groove 5, realizing that the filter paper is concentric with the rotating disk and the same central axis. Then tighten the nuts. Filter paper of the same specification can be directly placed into the position of the three positioning blocks. The operation is convenient, quick and practical. Next, the rotation power source (which can be a rotary motor) starts working and drives the rotating disk 1, the positioning seat 2 and the round filter paper to rotate through the same central axis 11. After the glue coating (or inkjet printing) process is completed, a new filter paper is placed in. If it is necessary to change to a different size of filter paper, the nuts on the three positioning blocks are loosened at the same time to adjust their positions accordingly.
