Abstract
The present invention relates to a processing and sealing method for an inclined oil hole of an air exhausting braking cylinder cover. The present invention comprises the following steps: an end surface is processed on a lateral surface of an air exhausting braking cylinder cover by a milling cutter with the diameter of 14mm; a long inclined hole is processed on the end surface, the hole diameter is 6mm, the hole depth is 103.3mm, and the included angle of the long inclined hole and the lateral surface is 50 DEG +/-0.5 DEG; a plug with the outside diameter of 6mm is arranged in the long inclined hole by a gun nozzle of a riveting gun lengthened by 8mm, and the air-operated working pressure of the riveting gun is from 5 kilograms to 7 kilograms. The present invention has the advantages of optimized processing technology, reduced steps, convenient operation, alleviated labor strength, increased production efficiency, no damage of workpieces, high safety and stable and reliable sealing for the long inclined hole.
Description
Technical field
The present invention relates to a kind of processing and encapsulating method of slant oil hole of air-exhausting braking cylinder cover.
Background technology
Exhausting braking cylinder cover is the special-purpose cylinder head of diesel exhaust gas brake apparatus, this cylinder head is to have increased by three oilholes on the basis of former Europe II cylinder head bore system, the pressure circuit of lubricating system when working in order to form diesel engine, the aperture that one long inclined oil hole of air is wherein arranged be φ 6mm, hole depth 103.3mm, with the side angle be 50 ° ± 0.5 °, processing technology is long inclined hole → φ 8mm hole, expansion side → φ 8.2MM hole, hinge side → manually squeeze into steel ball of φ 8.5mm of φ 12mm hole, ream side and plane → brill φ 6mm, and steel ball is realized the aperture sealing with interference fit.The processing of above-mentioned slant oil hole of air-exhausting braking cylinder cover and encapsulating method, its drawback is: 1, manually squeeze into steel ball, not only labour intensity is big, efficient is low,, and injure parts easily by a crashing object and industrial accident, poor stability occur; 2, operation is many, and production efficiency is low; When 3, squeezing into steel ball to squeeze into pressure uncontrollable, sealing effectiveness is not good enough.
Summary of the invention
The purpose of this invention is to provide that a kind of operation is few, good sealing effect, do not damage the processing and the encapsulating method of the slant oil hole of air-exhausting braking cylinder cover of parts.
In order to realize above-mentioned purpose, the processing of the slant oil hole of air-exhausting braking cylinder cover that is provided and encapsulating method comprise the steps: successively
A, on the side of exhausting braking cylinder cover, process an end face with the milling cutter of φ 14mm;
B, on end face, process the aperture be 6mm, hole depth be 103.3mm, with the side angle be 50 ° ± 0.5 ° long inclined hole;
C, in long inclined hole, be that external diameter is installed is the obstruction of 6mm for the rifle mouth of 5 kilograms-7 kilograms pulling rivet rifle lengthening 8mm with pneumatic operating pressure.
The cutting depth of end face is 8.5mm in the above-mentioned A step.
The formation method of stopping up in the above-mentioned C step is: the pulling rivet that the shank that will be connected as a single entity by pull bar with pull bar, external diameter is 6mm constitutes is put into the rifle mouth that pneumatic operating pressure is 5 kilograms-7 kilograms pulling rivet rifle lengthening 8mm, with the pulling rivet rifle pulling rivet is brought in the long inclined hole, by pulling rivet rifle pulling pull bar extruding shank, make shank generation plastic expansion and seal long inclined hole, when pull bar is broken, its broken end part is clamp-oned shank, and the shank rivet clasp is in long inclined hole.
The processing of slant oil hole of air-exhausting braking cylinder cover provided by the present invention and encapsulating method, optimized processing technology, substitute as the sealing parts by the formed obstruction of pneumatic tool with pulling rivet and manually to squeeze into steel ball, not only reduced the operation content, simplified operation, made things convenient for operation, alleviate labour intensity, improved production efficiency, do not damaged parts, security is good, and with the plastic expansion rivet clasp that shank produced of pulling rivet in long inclined hole, to the sealing of long inclined hole since employed be pneumatic tool pulling rivet rifle, thereby the shank of pulling rivet is squeezed into pressure and can be controlled, sealing to long inclined hole is reliable and stable, and high-mechanic pressure reaches 1500 kilograms.
Description of drawings
Fig. 1 is the former processes view of slant oil hole of air-exhausting braking cylinder cover;
Fig. 2 is a slant oil hole of air-exhausting braking cylinder cover processes view of the present invention.
The specific embodiment
With reference to Fig. 2, the processing of the described slant oil hole of air-exhausting braking cylinder cover of embodiment and encapsulating method comprise the steps: successively
A, to process a cutting degree of depth with the milling cutter of φ 14mm on the side that the exhaust brake cylinder needs be the end face of 8.5mm;
B, on end face, process the aperture be 6mm, hole depth be 103.3mm, with the side angle be 50 ° ± 0.5 ° long inclined hole;
C, in long inclined hole, be that external diameter is installed is the obstruction of 6mm for the rifle mouth of 5 kilograms-7 kilograms pulling rivet rifle lengthening 8mm with pneumatic operating pressure.The formation method of this obstruction is: the pulling rivet that the shank that will be connected as a single entity by pull bar with pull bar, external diameter is 6mm constitutes is put into the rifle mouth that pneumatic operating pressure is 5 kilograms-7 kilograms pulling rivet rifle lengthening 8mm, with the pulling rivet rifle pulling rivet is brought in the long inclined hole, by pulling rivet rifle pulling pull bar extruding shank, make shank generation plastic expansion and seal long inclined hole, when pull bar is broken, its broken end part is clamp-oned shank, and the shank rivet clasp is in long inclined hole.
Because pulling rivet is the product of public offering on the market, belongs to known technology, therefore no longer carefully state.
