Problems solved by technology

Since the alignment method is manually observed with eyes, on the one hand, it takes a long time to align and the efficiency of press-fitting is not high; on the other hand, the accuracy of alignment is poor, and the sliding bearing is easy to Misalignment may easily cause misalignment of sliding bearing installation, making it difficult to meet the requirements of consistent production

Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] Such as figure 1 , figure 2 As shown, the present invention is made of components such as base plate 1, first positioning pin 2, second positioning pin 3, spring 4, steel ball 5 and screws, wherein base plate 1 is a rectangular plate structure, and the left front corner of base plate 1 is vertically provided with The first positioning pin 2, the lower end of the first positioning pin 2 extends into the base plate 1, the lower end surface of the first positioning pin 2 is flush with the bottom surface of the base plate 1, and the first positioning pin 2 is fixedly connected with the base plate 1. A second locating pin 3 is vertically arranged at a position to the right of the middle part of the base plate 1. The lower part of the second locating pin 3 is integrally formed with an annular boss, and the lower end of the second locating pin 3 extends int...

Abstract

The invention discloses a pressing tool for a sliding bearing of a crankcase cover. A first positioning pin and a second positioning pin are vertically fixed on a base plate; the distance between the first positioning pin and the second positioning pin is same as that between an oil pump hole and a crankshaft hole in the crankcase cover to be assembled; a horizontal hole is arranged on the upper part of the second positioning pin; a spring and a steel ball are arranged in the horizontal hole; one end of the steel ball is supported against and connected with the spring; the other end of the steel ball is limited by a closing port for the hole port of the horizontal hole; and small part of a ball body of the steel ball extends out of the closing port of the hole port of the horizontal hole. According to the invention, by using the steel ball to determine the position of the sliding bearing, the sliding bearing is simpler and more convenient to align, the aligning accuracy of the sliding bearing can be ensured better, the mounting malposition of the sliding bearing can be effectively prevented, the consistent production can be ensured and the assembling efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of tooling fixtures, and in particular relates to a press-fitting tooling for crankcase cover sliding bearings. Background technique [0002] At present, when assembling the crankcase, various engine manufacturers rely on manual press-fitting of the sliding bearing into the crankshaft hole of the crankcase cover, that is, first place the crankcase cover on the work table, and then place the sliding bearing on the The crankcase cover is above the crankshaft hole, and then adjust the position of the sliding bearing so that the oil passage hole on the sliding bearing is aligned with the oil passage opening on the crankshaft hole wall on the crankcase cover, and finally manipulate the hydraulic press to press the sliding bearing into the crankshaft inside the hole. Due to the way of manually observing the alignment with eyes, on the one hand, it takes a long time to align and the efficiency of press-fitting...
