Problems solved by technology

The center line of the eccentric oil hole deviates from the center line of the solenoid valve hole, so that when the drill bit is processing the eccentric oil hole, when the front end of the drill bit enters the inner side of the solenoid valve hole, or from the solenoid valve hole When the other side of the drill bit is re-drilled into the part, because only one side of the drill bit is in contact with the solenoid valve hole, and the other side is suspended in the air, the drill bit is easily deflected or broken when it is feeding, which affects the machining accuracy and machining efficiency of the eccentric oil hole.

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] figure 1 Shown is a dual-clutch blank 1 in the prior art, which is a dual-clutch for automobiles. A plurality of electromagnetic valve holes 2 are arranged in parallel on the dual-clutch blank 1. According to design requirements, an eccentric oil hole 5 needs to be processed Intersect with all solenoid valve holes 2.

[0033] Such as figure 2 and image 3 As shown, the existing processing method is to directly drill holes with a drill bit 6 on the dual-clutch blank 1. When the other side of 2 passes through the solenoid valve hole 2, only one side of the drill bit 6 is in contact with t...

Abstract

The invention relates to a machine processing method, and especially relates to a double-clutch eccentric oil through processing method comprising the following steps: casting a double-clutch blank with a solenoid valve hole, arranging two protrusion portions on an inner wall of the solenoid valve hole, wherein the two protrusion portions are provided with parallel plane ends; processing an eccentric oil through crossing the solenoid valve hole on the double-clutch blank, wherein the eccentric oil through vertically penetrates the plane ends of the two protrusion portions; 3, processing to remove the protrusion portions in the solenoid valve hole. When a drill enters and penetrates the solenoid valve hole, a front end passes the plane ends on the protrusion portions, because the plane ends are vertical to the drill, so the drill cannot be deflected, thus ensuring processing precision and efficiency in eccentric oil through processing, and preventing the drill from being broken. The invention also discloses the double-clutch blank using the processing method.

Description

technical field [0001] The invention relates to a machining method, in particular to a machining method for an eccentric oil hole of a double clutch. Background technique [0002] In dual-clutch machining, it is necessary to process the eccentric oil hole on the part according to actual needs, that is, the solenoid valve hole is formed on the part first, and then the eccentric oil hole intersecting with the solenoid valve hole is processed. The center line of the eccentric oil hole deviates from the center line of the solenoid valve hole, so that when the drill bit is processing the eccentric oil hole, when the front end of the drill bit enters the inner side of the solenoid valve hole, or from the solenoid valve hole When the other side of the drill is re-drilled into the part, because only one side of the drill bit is in contact with the solenoid valve hole, and the other side is suspended in the air, the drill bit is easily deflected or broken when it is feeding, which af...
