Problems solved by technology

It is widely used in industry. For some occasions with high sealing requirements, two oil seals need to be installed. At this time, after the first oil seal is installed, it is only at the mouth of the installation hole. Because the oil seal has certain elasticity, the second oil seal The two oil seals will be elastically deformed when the first oil seal is squeezed, it is difficult to install in place, and if the installation is not in place, it is prone to leakage defects; if it is installed vigorously, it is easy to crush the oil seal

Embodiment Construction

[0020] The technical solution of the present invention will be described in further non-limiting detail below in conjunction with preferred embodiments and accompanying drawings.

[0021] Such as Figure 1 to Figure 4 As shown, the double oil seal press-in mechanism corresponding to a preferred embodiment of the present invention is used to sequentially press the first oil seal 1a and the second oil seal 1b into the mounting hole 2a of the workpiece 2, and the end surface 2e of the workpiece 2 is set There is a convex portion 2b and a stepped portion 2d surrounding the convex portion 2b. The mounting hole 2a is opened at the center of the convex portion 2b, and the convex portion 2b is also provided with a notch 2c communicating with the mounting hole 2a.

[0022] The double oil seal press-in mechanism includes a guide sleeve 3 and an extrusion part 4 movably connected with the guide sleeve 3 .

[0023] The center of the guide sleeve 3 is provided with a guide hole 3a and a p...

Abstract

The invention discloses a double oil seal press-in mechanism, which is used to sequentially press a first oil seal (1a) and a second oil seal (1b) into a workpiece (2). The workpiece (2) is provided with a convex portion (2b). A mounting hole (2a) for installing the oil seal (1) and a gap (2c) communicating with the mounting hole (2a) are opened in the center of the convex part (2b), and the double oil seal press-in mechanism includes a guide sleeve (3 ) and the extrusion part (4) movably connected with the guide sleeve (3), the extrusion part (4) includes a guide post (6) and one end connected to the guide post (6) for extruding The extruding part (6b) of the oil seal, the diameter of the extruding part (6b) is smaller than the outer diameter of the oil seal and the extruding part (6b) is provided with a protrusion matching the notch (2c) blocks (8). By arranging the protrusion that can be embedded in the notch of the workpiece, it can be ensured that both the first oil seal and the second oil seal can be installed in place, and no overpressure will occur.

Description

technical field [0001] The invention relates to a double oil seal press-in mechanism. Background technique [0002] The oil seal is a mechanical element used to seal grease (oil is the most common liquid substance in the transmission system, and also generally refers to the general liquid substance). Oil leaks. It is widely used in industry. For some occasions with high sealing requirements, two oil seals need to be installed. At this time, after the first oil seal is installed, it is only at the mouth of the installation hole. Because the oil seal has certain elasticity, the second oil seal The two oil seals will be elastically deformed when the first oil seal is squeezed, and it is difficult to install them in place. If they are not installed in place, leakage defects will easily occur; if they are installed vigorously, the oil seals will be easily crushed. Contents of the invention [0003] The purpose of the present invention is to provide a double oil seal press-in ...
