Description

A kind of guideway

Technical field

This utility model belongs to linear rolling guide manufacturing technology field, and in particular to a kind of guideway.

Background technology

Linear rolling guide is a kind of structure playing the guiding role, and in general machine, a part will be with respect to another Part is moved, therefore is accomplished by supporting and is oriented to, and guide rail just plays this effect, in the various tool machines such as lathe, quasiconductor system Make the various industrial equipments such as device, industrial robot to be widely used.And linear rolling guide is slide block straight line in guide rail bar Slide, and only this one degree of freedom, it is ensured that the motility of higher relative motion precision and low speed.

Slide block is a component on linear rolling guide, and when slide block is performed relative motion with guide rail, ball is just along cunning Rolling path rolling in block, raceway is entered back in slide block end ball further through back device into after back hole, and ball is like this all And carry out rolling movement with renewing, the motion secondary so as to realize linear guides.And in prior art, the die cavity in the middle part of slide block is general For arc or linear, install and have error, the fine angle of whole slide block is not high, and its machining accuracy is relatively low, and ball is being followed During ring, particularly at the junction point of the body of slide block and back device, ball is easily stagnated, and ball operation has some setbacks, and is caused straight The whole job stability of line guideway is poor so that correspondence is difficult to meet enterprise's production operation using the machine of the guideway Demand.

At present, domestic linear rolling guide manufacturer rests essentially within traditional handicraft rank for slide block processing technique Section, conventional process flow：Hot rolling material → sawed-off → milling is hexahedro → and corase grind hexahedro → milling straight flute → brills reverser installing hole, spin be logical Hole → brill attacks user installation hole → milling raceway (or cutting raceway) → heat treatment → fine grinding four sides → raceway molding mill.Traditional handicraft falls Afterwards complex steps, are not suitable for the nowadays fast-developing demand of machine tool equipment manufacturing industry.Especially by taking raceway manufacturing procedure as an example, Need through milling straight flute and milling raceway (cutting raceway) this two procedures, wherein milling raceway operation processing mode universal at present is special The mode of raceway is cut with molding cutter Milling Process or wire cutting, the dedicated tool high cost that the milling of special molding cutter is adopted, Working (machining) efficiency is low, and disqualification rate is high, high to craftsmanship's level requirement, and working (machining) efficiency is low；And wire cutting cut raceway high precision but Efficiency is lower, and pollutes big.Conventional machining process not only time and effort consuming but also waste of resource, do not meet green manufacturing, energy-saving and emission-reduction yet Spirit, be badly in need of a kind of more energy-efficient processing technique.

Quenching, used as a kind of technique that heat treatment must be used, its quenching medium has a significant impact to product quality tool.It is conventional In quenching medium, mostly quenched using animal and plant fat or mineral oil, or add other additives, but vegetable and animals oils contain not Satisfied fatty acid can hydrolyze or aoxidize generation penetrating odor, and mineral oil is easily heated generation oil smoke.And some other quenching Agent is for example a kind of as adopted poly- alkylene ethylene glycol for the quenching medium of primary raw material, during workpiece primary quenching, around workpiece Liquid temperature is once raised to more than the cloud point of solution, and just precipitation out, is suspended in and quenches PAG polymer in tiny liquid pearl form from solution In fiery liquid.As soon as the PAG liquid pearls of suspension touch red heat workpiece, adhere on surface of the work by its extraordinary wettability, into The peplos of rich water wrap up workpiece.PAG hardening medias are exactly the rate of cooling for leaning on this peplos to adjust water.Workpiece is cooled down After getting off, be attached on the polymer on workpiece again can back dissolving in quenching liquid.Back dissolving needs the time, and often waits not in producing Totally just workpiece is taken out from quenching liquid to polymer back dissolving, PAG polymer contents are often in the liquid that such workpiece is taken out of Higher than the content in quenching liquid used.For a long time, after a large amount of workpiece quenchings, the relative concentration of PAG is just inevitable in quenching liquid gradually drops It is low, and the gradually relative rising of the concentration of other additive components.In same concentrations, the PAG quenching liquids cooling for having used long Speed faster, can cause the hardening crack of workpiece.

The content of the invention

The purpose of this utility model is to solve the above problems, there is provided a kind of processing in accurate cold drawing molding slider type chamber Method, its accuracy of manufacture is higher, and manufacturing process is more simplified.

This utility model is employed the following technical solutions：A kind of processing method in accurate cold drawing molding slider type chamber, including with Lower step：

Step one, prepares slide block, by the sawed-off slide block into length slightly larger than L of the pull-up timber-used band sawing machine of precise cold；

Step 2, rough mills both ends of the surface, with the forward and backward both ends of the surface of horizontal milling machine milling raw material block so that the length base of slide block This is equal to L；

Step 3, corase grind is hexahedro, and with surface grinding machine six faces of slide block are ground so that slide block width is equal to W, slide block height Equal to H, its length is equal to L；

Step 4, bores reverser hole, spin through hole, and reverser peace is bored in the forward and backward both ends of the surface of slide block using machining center Dress hole 8-Ma, in the forward and backward both ends of the surface of slide block spin through hole is bored

Step 5, brill attacks user installation hole, is bored in upper end of slide block face using machining center and attacks user installation hole 4-Mb；

Slide block is quenched, is sent out orchid by step 6, heat treatment；

Step 7, refines datum level；With surface grinding machine datum level is refined to size W and H；

Step 8, raceway molding mill, with the molding of slide block special plane grinding machine raceway 4-R is refined.
