Description

Technical Field

[0001] The present invention relates to a filter tooling fixture, specifically a core grabbing fixture applied to the production and detection of filters. Background Art

[0002] At present, a filter generally includes a housing, a core, a check valve, a bypass valve, etc. Among them, the core can also be called a core assembly, which is composed of filter paper, end caps (including upper end cap and lower end cap), a central tube, etc. After the filter paper and the end cap are combined, generally, a steel wire is used to pull the end cap to detect the magnitude of the pulling force, so as to judge whether the combination firmness of the two meets the requirements. Its pulling force only reflects the combination firmness on one side, cannot achieve balance, is difficult to tighten the end cap and is easy to break, or multiple pulls at different positions are required to comprehensively detect the combination firmness of the two, resulting in low work efficiency and sometimes it is difficult to achieve comprehensive detection. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above technical deficiencies and provide a convenient core grabbing fixture that can quickly grab the core with balanced force.

[0004] The purpose of the present invention is achieved through the following technical solutions: A convenient core grabbing fixture, including a bracket. The bracket is in a cross shape, and the center position of the bracket is connected to an adjusting rod. Parallel movable rods are installed on both sides of the bracket, and hooks are installed at the other ends of the parallel movable rods.

[0005] The parallel movable rods are installed in groups of two on both sides of the bracket, with a total of four groups and eight rods. There are four hooks, and their heads are placed inward and upward, so as to evenly hook the end caps of the core from at least four directions. The upper ends of the parallel movable rods are respectively docked with the sides of the bracket through upper movable pins, and the lower ends of the parallel movable rods are respectively docked with the tails of the hooks through lower movable pins, which is convenient to respectively adjust the inclination directions and angles of the parallel movable rods and the hooks. An adjusting seat is installed on the adjusting rod.

[0006] After adopting the technical solution of the present invention, first adjust the inclination directions and angles of each group of parallel movable rods and the head angles of the hooks through the upper and lower movable pins. The hooks can hook the end caps of the core from four directions and partially penetrate into the filter paper for tightening, and evenly pull by operating the adjusting seat and the adjusting rod. Thus, the magnitude of the pulling force is detected to judge the combination firmness of the filter paper and the end cap. Its comprehensive detection work efficiency is high, effectively guaranteeing the quality of the core. Brief Description of the Drawings

[0007] Figure 1 It is a schematic installation structure diagram of the convenient core grabbing fixture of the present invention. Detailed Embodiment

[0008] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0009] As Figure 1 shown, the portable filter element gripping fixture of the present invention applied to the production and detection of filters includes a bracket 1. The bracket 1 is in a cross shape. The center position of the bracket 1 is connected to an adjusting rod 3 through (upper and lower fixing nuts 2). Parallel movable rods 4 are installed on both sides (downward) of the bracket 1, and hooks 5 are installed at the other ends of the parallel movable rods 4.

[0010] The parallel movable rods 4 are installed in groups of two on both sides of the bracket 1, with a total of eight rods in four groups. The hooks 5 are four in number, and their heads (i.e., hook parts) are placed inward and upward, so as to evenly hook the end caps of the filter element from at least four directions. The upper ends of the parallel movable rods 4 are respectively butted against the sides of the bracket 1 through upper movable pins 6, and the lower ends of the parallel movable rods 4 are respectively butted against the tails of the hooks 5 through lower movable pins 7, which is convenient for respectively adjusting the inclination directions and angles of the parallel movable rods and the hooks (adjusting the inclination directions and angles outward or inward according to the size of the filter element). An adjusting seat 8 is installed on the adjusting rod 3, which is convenient for docking with the tensile force detection test equipment by this adjusting seat.

[0011] When in use, first, prepare two sets of the "portable filter element gripping fixture" of the present invention. According to the size of the filter element, adjust the inclination directions and angles of each group of parallel movable rods 4 and the head angles of the hooks 5 through the upper and lower movable pins 6 and 7 first. Then, the hooks of the "portable filter element gripping fixture" (placed upright and above as shown in the figure) hook the upper end caps of the filter element from four directions and partially penetrate into the filter paper for tensioning. The hooks of another set of "portable filter element gripping fixture" (placed upside down and below in the opposite direction) hook the lower end caps of this filter element from four directions and partially penetrate into the filter paper for tensioning. Finally, place the assembly of these two sets of "portable filter element gripping fixtures" and the filter element into the tensile force detection test equipment. By pulling the adjusting seat, adjusting rod and bracket above, the upper end caps of the filter element are evenly pulled upward in four directions. Naturally, the adjusting seat, adjusting rod and bracket below evenly pull the lower end caps of the filter element downward in four directions accordingly, so as to detect the magnitude of the tensile force and judge the firmness of the combination of the filter paper and the end cap, effectively ensuring the quality of the filter element.
