Problems solved by technology

[0007] 2) The split structure of the existing sealing mechanism itself has the problem of complex structure, so that when disassembling and installing the sealing mechanism (maintenance or replacement of the sealing mechanism), it is necessary to separately repair the first sealing assembly between the front end cover and the cylinder body, the cylinder The second sealing assembly between the body and the rear end cover is disassembled or installed, so that the process of disassembly and installation requires multiple operations, which makes the disassembly process of the sealing mechanism very cumbersome, resulting in low disassembly efficiency of the existing sealing mechanism

Embodiment 1

[0049] This embodiment discloses a sealing mechanism for an automobile coating glue supply servo metering machine.

[0050] The glue supply servo dosing machine for automobile painting includes servo motor, reducer, screw rod, outlet shut-off valve, control system, front end cover 1, cylinder body 2, rear end cover 3, plunger 4 (piston rod) and sealing mechanism , wherein the front end cover 1, the cylinder body 2 and the rear end cover 3 are coaxially fixed and installed sequentially through the fixing bolts C, and an edge is formed between the front end cover 1, the cylinder body 2 and the rear end cover 3 (the front end cover 1, the cylinder body 2 and the rear end cap 3) the sealing cavity A that extends axially and is compatible with the outer diameter of the plunger 4. Moreover, in this embodiment, a puller 10 for assembly and disassembly is also disclosed correspondingly, which is the same as the puller commonly used in the prior art, and includes a puller jaw 101, a pu...

Embodiment 2

[0072] On the basis of the first embodiment, this embodiment discloses a disassembly method for the sealing mechanism of the glue supply servo quantitative machine for automobile painting.

[0073] like Figure 5 Shown: a disassembly method for the sealing mechanism of the glue supply servo quantitative machine for automobile painting, which is implemented based on the sealing mechanism in Example 1. When disassembling the sealing mechanism, the disassembly process includes the following steps:

[0074] Step 1: Remove the fixed bolts used to connect the front end cover, cylinder block and rear end cover, and remove the rear end cover and cylinder block accordingly, so that the cylinder body is separated from the front end cover and the sealing sleeve of the sealing mechanism, so that the sealing sleeve The disassembly groove on the top is exposed;

[0075] Step 2: Insert the puller claws of the provided puller for disassembly into the groove for assembly and disassembly on th...

Embodiment 3

[0079] On the basis of the first embodiment, this embodiment discloses the installation method of the sealing mechanism for the glue supply servo metering machine for automobile painting.

[0080] like Image 6 Shown: a method for installing a sealing mechanism for an automotive coating glue supply servo quantitative machine, which is implemented based on the sealing mechanism in Example 1. When installing the sealing mechanism, the installation process includes the following steps:

[0081] Step A: Correspondingly socket the sealing sleeve on the plunger, and make the front end of the sealing sleeve correspond to the installation groove on the front end cover. In this embodiment, each sealing member on the sealing sleeve should be installed on the sealing sleeve correspondingly and sealed firstly between the sleeve sealing sleeves.

[0082]Step B: Correspondingly socket the cylinder body on the rear end of the sealing sleeve, and socket the rear end cover on the rear end of ...

Abstract

The invention specifically relates to a sealing mechanism for an automobile coating glue-supplying servo quantitative machine, and a disassembly method and assembly method thereof. The sealing mechanism comprises a sealing sleeve, wherein the inner side wall of the sealing sleeve is arranged on a plunger in a sealing and sleeving manner; the end surfaces of the two ends of the sealing sleeve and the side wall of the periphery of the sealing sleeve are in seal fit with an installing groove formed in the inner side wall of a sealing cavity; the installing groove extends in the direction of the central axis of the sealing cavity, and extends from the middle position of a front end cover to the middle front position of a cylinder block; a first step seal and a second step seal are arranged atpositions, relatively close to the cylinder block, of the inner side wall of the sealing sleeve at an interval in the direction of the central axis of the sealing cavity; and a groove for disassembly,an opening end of which faces toward the cylinder block, is formed in a position, corresponding to the cylinder block, of the peripheral wall of the outer side of the sealing sleeve. The invention also correspondingly discloses the disassembly method and assembly method of the sealing mechanism. The sealing mechanism, the disassembly method and the assembly method can give consideration to the sealing effect and disassembly and assembly efficiency during gluing, and can better assist in improving the use effect of the coating glue-supplying servo quantitative machine.

Description

technical field [0001] The invention relates to the technical field of glue supply and sealing for automobiles, in particular to a sealing mechanism for a glue supply servo quantitative machine for automobile painting and a disassembly method thereof. Background technique [0002] In the existing automobile production process, in order to ensure the sealing, shockproof, noise reduction, corrosion resistance and comfort of the automobile, it is necessary to apply glue to the body (glue for the body is divided into glue for welding and glue for painting). In recent years, the coating of various glues is mainly based on robots, assisted by manual point filling, so precision quantitative equipment is the key equipment for glue coating. The quantitative methods of existing precision quantitative equipment mainly include precision gear quantitative, pressure flow closed-loop controlled quantitative and servo quantitative machines, among which the servo quantitative machine has the...
