Description

Technical Field

[0001] The present invention relates to a filter assembly tooling, and more particularly to a bypass valve assembly mechanism applied to filter production. Background Art

[0002] At present, an oil filter generally includes a housing, a screw plate, a filter element assembly, a check valve, a bypass valve, etc. The bypass valve includes a bypass valve body, a bypass valve spring, etc. The existing bypass valve assembly method is that an operator holds a tool (a clamp) to compress the bypass valve spring to a certain extent and then installs it into the bypass valve body. It is not easy to accurately control the compression degree of the bypass valve spring manually. Compressing too much will damage the elasticity, and compressing too little will not allow it to be installed. The working efficiency is low, and there is also a risk that the bypass valve spring will fly off and injure people if the compression control is not good. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above technical deficiencies and provide a bypass valve automatic assembly mechanism that can compress and control the bypass valve spring well and automatically install it into the bypass valve body.

[0004] The purpose of the present invention is achieved through the following technical solutions: A bypass valve automatic assembly mechanism includes a bottom plate. A workpiece fixing block is installed on the bottom plate. A downward pressing power source is installed at the longitudinal position of the bottom plate and above the workpiece fixing block. A positioning block is installed at the lateral position of the bottom plate, at the side of the workpiece fixing block and below the downward pressing power source. A spring pushing block is installed in the positioning block, and the spring pushing block is connected to a feeding power source.

[0005] The positioning block has an inwardly concave U-shaped structure. A guiding groove is provided at the inwardly concave position of the positioning block, and the spring pushing block is installed on the guiding groove. The front part of the spring pushing block has an inwardly concave arc corresponding to the shape of the bypass valve spring. The downward pressing power source and the feeding power source are respectively electrically connected to a microcomputer control box.

[0006] After adopting the technical solution of the present invention, place the bypass valve body between the positioning block and the workpiece fixing block on the bottom plate. The bypass valve spring is erected and installed on the guiding groove of the positioning block, below the downward pressing power source, and abuts against the inwardly concave arc of the spring pushing block. First, the downward pressing power source compresses the bypass valve spring downward to a set range, and then the feeding power source drives the spring pushing block to automatically push the compressed bypass valve spring along the guiding groove into the inside of the bypass valve body, thus completing the automatic assembly of the bypass valve spring and the bypass valve body to form a bypass valve finished product. The present invention accurately controls the compression degree of the bypass valve spring, and the compression amount is consistent. The bypass valve spring is smoothly pushed into the bypass valve body and will not fly off, eliminating potential safety hazards to people. Its assembly work efficiency is high, ensuring the quality of the bypass valve finished product. Brief Description of the Drawings

[0008] Figure 2 It is Figure 1 a schematic structure diagram of the assembly of the bottom plate, workpiece fixing block and positioning block in Specific embodiments

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

[0010] As Figure 1 , Figure 2 shown, the bypass valve automatic assembly mechanism of the present invention applied to the production of filters includes a bottom plate 1, on which a workpiece fixing block 2 is installed. Above the (diagonal side) of the workpiece fixing block 2 at the longitudinal position of the bottom plate 1, a downward pressing power source 4 (a downward pressing cylinder) is installed through a downward pressing mounting plate 3. At the lateral position of the bottom plate 1, and at the side (front position) of the workpiece fixing block 2 and below the downward pressing power source 4, a positioning block 7 is installed. A spring push block 9 is installed in the positioning block 7, and the spring push block 9 is connected to a pushing power source 6 (a pushing cylinder). The pushing power source 6 is installed on the bottom plate 1 through a pushing mounting plate 5, and the positioning block 7 is located between the workpiece fixing block 2 and the pushing power source 6.

[0011] The positioning block 7 has an inwardly concave U-shaped structure. A guiding groove 8 is provided at the inwardly concave position of the positioning block 7 (as Figure 2 shown). The spring push block 9 is installed on the guiding groove 8 (for installing and placing the bypass valve spring 10 and the spring push block 9). The front part of the spring push block 9 has an inwardly concave arc corresponding to the shape of the bypass valve spring. A bypass valve body 11 is placed between the positioning block 7 and the workpiece fixing block 2 on the bottom plate 1. The bypass valve spring 10 is erected on the guiding groove 8 of the positioning block, below the downward pressing power source 4, and abuts against the inwardly concave arc of the spring push block 9. The downward pressing power source 4 and the pushing power source 6 are respectively electrically connected to a microcomputer control box 12, which is uniformly regulated by it. The assembly working principle of the present invention is as follows: First, the downward pressing power source 4 works to compress the bypass valve spring 10 downward to a set range (the maximum compression reaches the top of the positioning block), and then the pushing power source 6 works to drive the spring push block 9 to automatically push the compressed bypass valve spring 10 along the guiding groove 8 into the interior of the bypass valve body 11. At the same time, the workpiece fixing block 2 holds the bypass valve body to prevent it from moving, so as to automatically complete the automatic assembly of the bypass valve spring and the bypass valve body to form a finished bypass valve.
