Embodiment I

[0031] Concrete embodiment 1: be example with processing V-type 12 cylinders inner body bearing block sidewalls. Such as figure 1 , 6 left cutter heads 13 and 6 right cutter heads 14 are installed on the main shaft 17 at a certain distance by 6 positioning sleeves 16, 6 bearing seats 15, and 1 main bearing seat 12, and the main nut 19 passes through the main positioning The sleeve 18 is fastened, and then fixed to the supporting body 11 by each bearing seat to form a cutter assembly 4 .

[0032] The cutter assembly 4 is installed on the column slide 6 through the support body 11 , and the taper shank at one end of the main shaft 17 of the cutter assembly 4 is installed in the output taper hole of the headstock 5 . During operation, the control system 20 controls the rotation of the servo motor 9 in the Z direction, and drives the tool assembly 4 to perform linear motion in the Z direction.

[0033] The working process of machining the side wall of the bearing seat of the mac...

specific Embodiment II

[0035] Specific embodiment II: Taking the processing of the side wall of the bearing block of the in-line 6-cylinder engine block as an example, the process includes the following steps:

[0036] (1) According to the cylinder center distance of the in-line 6-cylinder body and the processing size of the side wall of the bearing seat, the in-line 6-cylinder cutter is equipped.

[0037] (2) The fixture 3 of the present invention can also take into account the installation of the in-line 6-cylinder body, so that parts can be replaced without changing the fixture.

[0038] The in-line 6-cylinder machine body bearing seat side wall machining process is the same as the V-shaped machine body machining process in the specific embodiment 1 except that the in-line 6-cylinder cutter needs to be replaced, so it will not be repeated here.

[0039] It needs to be clarified that the control system 20 can send driving signals to the Z-direction servo motor 9 and the X-direction servo motor 10 ...

Abstract

The invention provides a cutter assembly and device for machining side walls of bearing pedestals and application. The cutter assembly and device for machining the side walls of the bearing pedestalsand the application aim to solve the problems that in the prior art, equipment mechanisms for machining the side walls of the bearing pedestals of large and medium machine bodies are unreasonable, sothat the working efficiency is low, and the machining quality is low. The cutter assembly comprises a supporting body, the main bearing pedestal, a plurality of cutter mechanisms and a main shaft, wherein the main bearing pedestal and the cutter mechanisms are all arranged on the supporting body; the main shaft is arranged on the main bearing pedestal and the cutter mechanisms at the same time; the cutter assembly is characterized in that each cutter mechanism comprises the corresponding bearing pedestal, a plurality of left cutter heads and a plurality of right cutter heads; the bearing pedestals are all arranged on the supporting body; the main shaft is arranged on the bearing pedestals at the same time; and the left cutter heads and the right cutter heads are arranged on the main shaftand arranged on the two sides of any bearing pedestal correspondingly. According to the cutter assembly and device for machining the side walls of the bearing pedestals and the application, under thecondition that a clamp is not replaced, machining of series V-shaped machine bodies of different lengths and machining of various in-line machine bodies can be achieved at the same time, and high economic efficiency is achieved.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, and in particular relates to a tool assembly, device and application for machining the side wall of a bearing seat. Background technique [0002] The body is the skeleton of the diesel engine, which is used to install moving parts such as the crankshaft and fixed parts such as the cylinder head. Among them, the crankshaft is the most important moving part installed on the body. [0003] The crankshaft is installed in the main shaft hole of the body, and the main shaft hole is composed of the semicircle of the body bearing seat and the semicircle of the bearing cap installed on the bearing seat. The main shaft hole is distributed in multiple levels along the longitudinal direction of the machine body. Due to the compact structure of the body cavity, the side walls at both ends of the bearing seat of the body need to be processed to prevent the diesel engine from interfering with the cranksh...
