Embodiment Construction
[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] Such as figure 1 - Figure 4 As shown, a presser for press-fitting crankshaft front oil seal and rear oil seal provided by the present invention includes a driving device and a press-fitting device connected with the driving device, and the driving device is used to drive the press-fitting device to move up and down so that Realize that the press-fitting device compresses the oil seal to realize the assembly of the oil seal and the crankshaft through hole. In the present invention, in combination with the drawings and image 3 As shown, the pressing device mainly includes:
[0024] The rear oil seal head 15 is a hollow shaft-shaped body, wherein the bottom outer wall of the rear oil seal head 15 is slidably mounted with a first positioni...

The invention discloses a press-mounting machine for press-mounting of a front oil seal and a rear oil seal of a crankshaft. The press-mounting machine comprises a driving device and a press-mounting device connected with the driving device. The press-mounting device comprises a rear oil seal pressing head and a front oil seal pressing head. The rear oil seal pressing head is a hollow shaft-shaped body, a first positioning pressing sleeve is mounted on the outer wall of the bottom of the rear oil seal pressing head in a sliding mode, and a first cavity used for mounting the rear oil seal is defined by the inner wall of the first positioning pressing sleeve and the bottom end of the rear oil seal pressing head. The front oil seal pressing head is of a cylindrical structure and is inserted into the rear oil seal pressing head, and the bottom end of the front oil seal pressing head extends out of the rear oil seal pressing head. A second positioning pressing sleeve is mounted on the outer wall of the bottom of the front oil seal pressing head in a sliding mode, and a second cavity used for mounting the front oil seal is defined by the inner wall of the second positioning pressing sleeve and the bottom end of the front oil seal pressing head. By means of the press-mounting machine for press-mounting of the front oil seal and the rear oil seal of the crankshaft, the front oil seal and the real oil seal are mounted in a pressing mode through one set of press-mounting device, and the problems that existing crankshaft front and rear oil seal press-mounting machines are high in cost and complicated in replacement are solved.
Description
technical field [0001] The invention relates to the field of installation devices for crankshaft oil seals, in particular to a press-fitting device for press-fitting the front oil seal and the rear oil seal of the crankshaft. Background technique [0002] Assembling the front oil seal and rear oil seal of the crankshaft, the oil seal needs to be press-fitted to the oil seal bracket first, and then installed on the engine as a whole. Generally, a manual press or a pneumatic press-fitting machine is used for press-fitting. The oil seal is equipped with different press-fitting devices for press-fitting, using two press-fitting machines or using one press-fitting machine to replace the pressure head for switching. Or use a press-fitting machine for press-fitting, and realize the press-fitting of the front and rear oil seals by replacing the press head. Due to long-term replacement of the press head, the wear accuracy of the press head will decrease, which will affect the sealing...
