no. 1 approach

[0022] Such as figure 1 , figure 2 As shown, a processing tool for the waterproof groove of the ignition coil casting cover includes a bottom plate 1, a positioning pin 2, a pressure plate 3, and a base 4; the structure of the bottom plate 1 is consistent with the structure of the waterproof groove of the cover to prevent the casting cover from interfering with the milling cutter during processing, and the size is larger than The size of the outer edge of the waterproof groove of the casting cover is smaller than that of the outer edge of the casting cover. The positioning pin 2 fixes the casting cover on the bottom plate 1, and the 6 pressure plates 3 are evenly distributed in the length direction of the bottom plate 1 to clamp the casting cover to ensure the clamping. After installing the casting cover, use a dial indicator to measure the runout of the casting cover end surface, which is not more than 0.05. One end of the base 4 is fixed on the workbench, and the other end ...

no. 2 approach

[0024] Such as image 3 As shown, a processing tool for the waterproof groove of the ignition coil casting cover includes a bottom plate 1, a positioning pin 2, a pressure plate 3, and a base 4; the structure of the bottom plate 1 is consistent with the structure of the waterproof groove of the cover, and its size is larger than that of the outer edge of the waterproof groove of the casting cover, but smaller than that of the casting The size of the outer edge of the cover, the positioning pin 2 fixes the casting cover on the bottom plate 1, and a pressure plate 3 clamps the casting cover to save clamping time and ensure that the clamping is firm and secure. After installing the casting cover, use a dial gauge to measure the casting cover The runout of the end surface is not more than 0.05. One end of the base 4 is fixed on the workbench, and the other end is installed on both sides of the bottom plate 1 . The positioning pins 2 are at least two on one side of the length direc...

Abstract

The invention relates to an ignition coil casting cover capillary groove processing tool and a processing method, and belongs to the technical field of machining. The ignition coil casting cover capillary groove processing tool comprises a bottom plate (1), a locating pin (2), a pressing plate (3) and a base (4), wherein the structure of the bottom plate (1) and the structure of a cover capillarygroove are consistent; the size of the bottom plate is larger than the size of the outer edge of the casting cover capillary groove and is smaller than the size of the outer edge of a casting cover; the casting cover is fixed onto the bottom plate (1) through the locating pin (2); the pressing plate (3) tightly clamps the casting cover, so that the firmness in clamping and fastening is ensured; after the casting cover is installed, the end surface runout of the casting cover is measured through a dial indicator and is not larger than 0.05; one end of the base (4) is fixed onto a working table;and one end of the base (4) is arranged on two sides of the bottom plate (1). According to the ignition coil casting cover capillary groove processing tool and the processing method provided by the invention, the processing tool and the processing method are added, so that the problem of water leakage of a complete machine caused by the part deformation tolerance is effectively solved. Particularly, for mass production products, the quality of a part waterproof effect directly influences the performance of the complete machine, and the part qualification rate reaches to 100 percent after processing.

Description

technical field [0001] The invention relates to a processing tool and a processing method for a waterproof groove of an ignition coil casting cover, belonging to the technical field of mechanical processing. Background technique [0002] The waterproof groove of the ignition coil cover is processed by the lathe to indirectly ensure the depth of the groove. Due to the large amount of deformation of the casting blank, water leakage often occurs due to the unqualified depth of the cover groove (out of tolerance deformation), which affects the performance of the whole machine. Contents of the invention [0003] The purpose of the present invention is to provide a casting waterproof groove processing tool and processing method, which can control the amount of deformation to ensure the groove depth requirements. [0004] The technical solution of the present invention is: a processing tool for the waterproof groove of the ignition coil casting cover, which is characterized in t...
