JPH06296809A - Manufacture of cartridge type filtrater with nut - Google Patents

Abstract

PURPOSE:To make special tools unnecessary for filter medium exchange and improve the exchange work efficiency in an engine room by fixing, for example, a hexagonal nut in the head part of a filtrater cylinder positioned on the opposite side of the bottom of a cartridge-type filtrater having a through hole, works as a filtrater screwing screw as well, in the bottom plate of a filtrater. CONSTITUTION:A hexagonal nut 19 or a wrench-applying device is attached to a head part of a filtrater cylinder 11 positioned on the opposite side of the bottom of a cartridge-type filtrater having a through hole, which works as a filtrater screwing screw as well, in the base bottom part of the filtrater. Among fixing methods, there are a thermal resistance type adhesive, solder welding, resistance spot welding, electron beam welding, arc welding, etc. To exchange the cartridge-type filtrater, a spanner is applied to the hexagonal nut 19 at the head part of the filtrater cylinder 11 or a wrench is applied in the case where the nut is wrench-applying type and when they are rotated right or left, the cartridge-type filtrater also rotates and thus the filter medium can be attached or detached easily.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge type filter manufacturing method in which a wrench hooking device is already mounted on the head of FIG. Filter for engine fuel. Filter for Lubricating Oil Cartridge type filter which can be easily attached and detached by a general tool wrench when replacing the filter for hoist hydraulic oil and the filter for other liquid substances.

[0002]

2. Description of the Related Art When replacing cartridge type filtration
As an example, the special tools shown in Fig. 10 and Fig. 11 were prepared in advance for the desorption work. Or, in the case of cartridge type filtration in a part of foreign car, 13 The clutch that connects the rotation only when loosening it on the head of the filter cylinder is possible only when removing the clutch. (The time when it was started by inserting it into your body by turning it with your arm's strength.) How to remove it by turning it with a lever by sandwiching the iron side in the difference between the two mountain shapes similar to the one attached to this engine shaft

[0003]

When the cartridge type filter is replaced 11 When oil is attached around the filter tube, the special holding tool is slippery during rotation due to the oil film, which makes it difficult to attach and remove. is there

[0004]

[Means for Solving the Problems] In recent years, since the space of the engine room is overcrowded due to the installation of high-tech equipment, there is little space for rotating special tools as shown in FIG. 10 and FIG. The object is to provide a method for manufacturing a cartridge type filter which is limited and solves these problems.

[0005]

In order to achieve the above-mentioned object, the head portion of the filter tube 13 is shown in FIG. 5, FIG. 6, FIG. 7 and FIG.
2 and the wrench hooking device shown in FIG.

In order to achieve the above-mentioned object, a conventional cartridge type filter as shown in FIG. Solder welding. Resistance spot welding. Electronic beam welding. Possible arc welding method

[0007]

[Function] 11 A tool is attached to the wrench hooking device on the 13 head of the filter tube. Fig.1 Since the wrench hooking device is already equipped, rotating it to the left or right with the standard tool causes the cartridge filter to rotate at the same time. Detachable

[0008]

[Actual rotation example] The cartridge type filter with nut shown in Fig. 3 can be quickly replaced by using a 14 spanner wrench as shown in Fig. 1.

[0009]

Since the present invention is constructed as described above, it has the following effects.

FIG. 9: 11 cartridge filter type presently present wrench hooking device having various kinds of filter cylinder diameters.
If the head of the 13 filter cylinder in Fig. 2 is designed so that the size of general tools can be used, even if it is exported to domestic and foreign countries (one example is a car), special tools are unnecessary, and one example is in a narrow engine room. The replacement work rate is improved.

[Brief description of drawings]

FIG. 1 is a wrench hooking device of 15.16.17.19 in which a hexagonal nut is mounted on the center of FIG. 4 and fixed to the head of a filter tube so that it can be rotated by 14 spanners. It is the figure which looked at the cartridge type filter with a nut from the slanting upper part.

FIG. 2 is an integrated cartridge which is formed by setting a mold capable of forming a mold 15.16.17.19 having a desired shape in advance when press-drawing a filter head of 11 filters. FIG. 3 is a view showing an example of a filter cylinder, which is also a view of the cartridge type filter with a wrench hanging device as seen from an obliquely upper portion.

FIG. 3 is a schematic view of a filter for oil in which a wrench hanging device of the present invention is attached to a cartridge-type filter used in a general automobile engine.

FIG. 4 is a view of a wrench-hanging mounting substrate in which a metal plate is formed into a desired thickness.

FIG. 5 is a diagram of a wrench hooking device in which the shape is a square pillar shape at the center of FIG. 4 and a desired height is provided and a square hole is provided at the center of the square so that a general screwdriver tool can be fitted. is there.

FIG. 6 is a view of a wrench hooking device formed in a rectangular column shape in a central portion of FIG. 4 to have a desired height.

7 is a view of a wrench hooking device in which a hexagonal hole is provided in the center of a hexagonal nut shape in the center of FIG. 4 so that a convex male hexagonal bar wrench of a general screwdriver can be fitted.

[FIG. 8] A cartridge type filter commonly used these days includes a thin metal tube 11 and a filter liquid passage hole at the bottom of the tube and an inlet / outlet port. There is a filter paper in the inside, and when replacing it, see Fig. 1.
The body is a complete replacement, and the figure is a perspective view as seen from the bottom of the cartridge type filter.

FIG. 9 is a cross-sectional view of a cartridge type filter used for a general engine.

[Fig. 10] Fig. 10 shows the three crown type tools that have been used recently. It is a figure of a detachable tool which covers 13 heads with a detent device having a polygonal shape and fits 1 and 1 and inserts a wrench into a central angle hole of a three-crown attachment type for use.

FIG. 11 is a view showing that the cartridge type strainer is fastened by using the conventional holding type detachable special tool.
