Abstract
The invention discloses a pull rod machining process. The process comprises the following steps: (1) turning a material and determining the total length: a material is turned to 245 mm by a lathe; (2) turning a thread: a thread of M30 of a pull rod is turned by the lathe; (3) chamfering: the two ends of the pull rod are chamfered by 4*45 degrees by the lathe; (4) a square with an edge length of 24 mm is milled at a position 55mm away from one end by a milling machine, and a second square with an edge length of 24 mm is milled at a position 55mm away from the first square; and (5) the finished product is checked and warehoused. The process comprises the steps of material turning by the lathe, thread turning, chamfering and machining by the milling machine for satisfying the production requirements, improves the size precision and the strength of the pull rod to enable the pull rod to satisfy the requirements, reduces the defective rate, and reduces the production cost.
Description
Technical field
The present invention relates to a kind of processing technology of pull bar, belong to Machining Technology field.
Background technology
Existing a variety of method is manufactured with to pull bar, but all there are this some problems, such as pull bar insufficient strength, pull bar size inaccuracy, global shape is undesirable, and such pull bar can not be met the need of market, and is unfavorable for carrying out smoothly of production, therefore in order to better enable pull bar meet the demands, proposing a kind of technological method for processing and solving this problem.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of processing dimension accurately, the processing technology of the pull bar of satisfactory quality.
Technical solution of the present invention is achieved in that a kind of processing technology of pull bar, the first step: car material top overall length, with lathe by stores van to 245mm; Second step: cutting thread, with the screw thread of lathe by trolley M30; 3rd step: chamfering, carries out 4*45 ° of chamfering by pull bar two ends lathe; 4th step: with the square of milling machine at distance one end 55mm place milling length of side 24mm, again apart from the square of square 55mm place milling second length of side 24mm after milling is complete; 5th step: the product completed is tested and warehouse-in.
Preferably, in the 4th step, foursquare size dimension acceptability limit is 23.5-24mm.
Preferably, in the 5th step to material test selective examination time, carry out outward appearance sampling observation and size inspect by random samples, outward appearance inspects 10 by random samples, and size inspects 6 by random samples.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The processing technology of a kind of pull bar of the present invention, by using the processing step of lathe car material, cutting thread, chamfering, milling machine processing, meeting production requirement, improving dimensional accuracy and the intensity of pull bar, making it meet the requirements, reduction in the numbers of seconds, reducing production cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:

Accompanying drawing 2 is the finished product schematic diagram of the processing technology of a kind of pull bar of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
As accompanying drawing 1,2 is depicted as the processing technology of a kind of pull bar of the present invention, embodiment one: the first step: car material top overall length, with lathe by stores van to 245mm, the total length of pull bar is determined; Second step: cutting thread, with the screw thread of lathe by trolley M30, does screw rod by the cutting thread of pull bar outer surface; 3rd step: chamfering, carries out 4*45 ° of chamfering by pull bar two ends lathe; 4th step: with the square of milling machine at distance one end 55mm place milling length of side 23.5mm, again apart from the square of square 55mm place milling second length of side 23.5mm after milling is complete; 5th step: test and warehouse-in to the product completed, carry out outward appearance sampling observation and size sampling observation, outward appearance inspects 10 by random samples, and size inspects 6 by random samples.
Embodiment two: the first step: car material top overall length, with lathe by stores van to 245mm, the total length of pull bar is determined; Second step: cutting thread, with the screw thread of lathe by trolley M30, does screw rod by the cutting thread of pull bar outer surface; 3rd step: chamfering, carries out 4*45 ° of chamfering by pull bar two ends lathe; 4th step: with the square of milling machine at distance one end 55mm place milling length of side 24mm, again apart from the square of square 55mm place milling second length of side 24mm after milling is complete; 5th step: test and warehouse-in to the product completed, carry out outward appearance sampling observation and size sampling observation, outward appearance inspects 10 by random samples, and size inspects 6 by random samples.
The processing technology of a kind of pull bar of the present invention, by using the processing step of lathe car material, cutting thread, chamfering, milling machine processing, meeting production requirement, improving dimensional accuracy and the intensity of pull bar, making it meet the requirements, reduction in the numbers of seconds, reducing production cost.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
