Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the present invention will be further described:

[0035] figure 1 Shown is an installation tool for a car process hole sealing plug, including a sleeve 1, a thimble 2 and a return spring 3, the sleeve 1 is arranged outside one end of the thimble 2, and the other end of the thimble 2 is provided with a handle 21, the sleeve 1 and thimble 2 are coaxial after assembly, the inner surface of sleeve 1 and the outer surface of thimble 2 are polished smooth, and thimble 2 can move axially relative to sleeve 1. The end of the sleeve 1 is closed in a frustum shape so as to cooperate with the sealing plug 7. There is a guide groove 11 on the sleeve 1, and a pin hole 22 is opened on the part of the thimble 2 corresponding to the guide groove 11. The positioning pin 6 Through the guide groove 11 and the pin hole 22 , the positioning pin 6 can move in the guide groove 11 along with the axial movement of the thimble 2 to play a guiding...

Abstract

The invention relates to a mounting tool of a sealing and blocking piece of a car auxiliary hole and a working method thereof. The mounting tool of the sealing and blocking piece of the car auxiliary hole is characterized in that the mounting tool comprises a sleeve (1), an ejector pin (2) and a reset spring (3), the sleeve (1) is arranged on the front portion of the ejector pin (2), the sleeve (1) and the ejector pin (2) are coaxially assembled, and the ejector pin (2) moves axially relative to the sleeve (1) to clamp a sealing and blocking piece (7) into the auxiliary hole. One end of the reset spring (3) is arranged on the outer portion of the sleeve (1) through a spring lower base (4), the other end of the reset spring (3) is arranged on the ejector pin (2) through a spring upper base (5), and the reset spring (3) enables the ejector pin (2) to reset to an initial state after work is completed. A handle (21) is further arranged at the rear end of the ejector pin (2). The mounting tool of the sealing and blocking piece of the car auxiliary hole is simple in structure and convenient to carry, greatly reduces labor intensity of workers, and guarantees mounting quality of the sealing and blocking piece.

Description

technical field [0001] The invention belongs to the field of special tools for the production and manufacture of automobile bodies, and in particular relates to an installation tool and a working method of a sealing plug for a process hole of a car. Background technique [0002] Due to the continuous improvement of the anti-corrosion quality requirements for the inner cavity of the car body, at present, all cars at home and abroad stamp an appropriate amount of circular process holes at the cross beam of the body floor. , so as to avoid the residual tank liquid in the inner cavity of the body from being brought into the next process to cause cross-contamination of the tank liquid. This kind of process hole is finally completely sealed manually in the last process of the painting workshop. In order to prevent the sealing plug from falling off later, the plug is designed as a hard and highly elastic plastic part. During the installation process, it needs to be manually squeeze...
