Embodiment Construction

[0040] The present invention is described in detail below in conjunction with accompanying drawing:

[0041] refer to figure 1 and Figure 5 , A cracking processing device for a crankcase bearing seat according to the present invention includes a machine base 23, a cracking mechanism A, a box positioning mechanism B and a slider mechanism C.

[0042] refer to figure 2 4, the crankcase bearing housing 12 to be processed includes the crankcase body and 5 to 7 bearing housings 8 with the same structure, and the 5 to 7 bearing housings 8 with the same structure are evenly distributed on the top of the crankcase body, and the crankshaft The box body and 5 to 7 bearing seats 8 with the same structure are integrated into one body. After the cracking process is completed, the 5 to 7 bearing seats 8 with the same structure are broken into bearing bases and bearing caps 24, and the 5 to 7 bearing bases are still connected to connected to the crankcase.

[0043] refer to figure 1 ,...

Abstract

The invention discloses a fracture splitting device for a bearing seat of a crankcase body, for overcoming the problems of large size of the existing equipment, complex working process, and high machining difficulty and manufacturing cost of a wedge-shaped pull rod. The fracture splitting device comprises a seat (23), a fracture splitting mechanism (A), a case body positioning mechanism (B) and aslide block mechanism (C), wherein the fracture splitting mechanism (A) comprises a workbench frame (1) and an expansion breaking pull rod (9); the case body positioning mechanism (B) comprises a fixing plate (16) and a rack (22); the slide block mechanism (C) comprises a right x-axis workbench (18); and the case body positioning mechanism (B) is installed at the right end of the seat (23) throughthe rack (22), the fracture splitting mechanism (A) is installed at the left end of the seat (23) through the workbench frame (1), the expansion breaking pull rod (9) is parallel to the rack (22) andthe fixing plate (16), the slide block mechanism (C) is installed at the front end of the rack (22), and the rotation axis of the fourth ball screw of the right x-axis workbench (18) is parallel to the fixing plate (16).

Description

technical field [0001] The invention relates to a processing device for a bearing seat of an engine crankcase body, more precisely, the invention relates to a cracking processing device for a bearing seat of an engine crankcase body. Background technique [0002] The engine crankcase bearing housing is made up of many bearing housings 8 and bearing caps 24 (a six-cylinder engine crankcase body has seven bearing housings and seven bearing caps). The traditional processing method is separate processing, that is, the bearing cover and the bearing seat (the bearing seat and the cylinder body are cast as a whole) are cast separately, and then the joint surfaces are milled and ground separately, and the bolt holes are processed separately. The traditional processing technology has low production efficiency, high manufacturing cost and poor assembly accuracy. [0003] The cracking process of the crankcase bearing seat is to first process cracking grooves on both sides of the cente...
