Abstract
The utility model provides a boring lathe with two functions of deep hole and honing, aiming at the problem that some enterprises which produce hydraulic cylinders have no honing machines and the defect that the function of the boring lathe is single to cause the boring lathe not to be fully utilized. The boring lathe comprises a boring rod main spindle box, the front end of which is connected with a honing rod in a removable way, and a honing head post rod is arranged in the honing rod which is connected with a hydraulic cylinder at the rear of the boring rod main spindle box. The front end of the honing head post rod is fixed with a honing head, the outside of which is provided with an emery stick box. After being increased with a set of honing system, the boring lathe not only solves the rotation problem of a hydraulic cylinder piston rod, improves the quality of the product, but also improves the utility ratio and the work efficiency of a deep hole boring lathe, and has the advantages of simple operation, easy enforcement, good honing effect, and popularization and application value.
Description
Technical field
The utility model relates to a kind of boring machine, particularly a kind of boring machine that has honing function concurrently.
Background technology
Hydraulic cylinder is that the fluid energy that oil pump is produced finally is transformed into mechanical energy, in executing agency, realize reciprocating a kind of Hydraulic Elements, hydraulic cylinder is widely used in industries such as aviation, metallurgy, machinery, water power, harbours as the brothers of machine.
The quality of hydraulic cylinder can directly influence the operation of executing agency, and at present, the processing technology means that cylinder inner bore is commonly used are: after the deep hole machining, adopt super precision method to reach the dimensional accuracy and the surface roughness of endoporus.Super essence is not subjected to the restriction of size adjustment, cost is low, but the hydraulic cylinder that processes can produce rotation in running, reason be super when smart super refined grinding wheel and workpiece 20-30 ° beat is arranged, so just formed spiral helicine machining locus on the surface of cylinder inner bore, piston is just walked along helical trajectory in running, when being stretched out, piston rod produces rotation, hydraulic cylinder will cause the screw thread of tailpiece of the piston rod and connector to break away from after operation a period of time, and executing agency can not normally be moved.
Honing is the method that effectively solves super smart drawback, and this just needs honing machine, but purchase honing machine production cost is significantly increased.Produce the boring machine that enterprise had of hydraulic cylinder, usually after bore hole and be in idle state, be unfavorable for making full use of of equipment again.
The utility model content
The problem that does not have honing machine at the enterprise of some production hydraulic cylinder, and existing boring machine function singleness, the drawback that can not be fully used, the utility model provides a kind of boring machine that has deep hole and two kinds of functions of honing concurrently, only need simply to change on existing boring machine basis, this boring machine just can have honing function.
Described purpose is achieved by the following scheme:
Deep hole, the dual-purpose boring machine of honing, it comprises the spindle of boring bar case that is arranged on boring machine lathe bed one end, described spindle of boring bar case front end is connected with honing lever by removable mode, and the honing head push rod is installed in the honing lever, and described honing head push rod is connected with the hydraulic cylinder that is arranged on spindle of boring bar case rear; The front end of described honing head push rod is fixed with honing head, and the outside of described honing head is provided with the emery stick box.
Described hydraulic cylinder is fixed on the main spindle box by adpting flange, and described hydraulic cylinder is communicated with hydraulic system, and controls by control cabinet.
The other end at the boring machine lathe bed is provided with headstock, described headstock is connected with the chuck of middle band through hole, be provided with cooling and rinse-system with the other end of the corresponding headstock of chuck, the tube wall of this cooling and rinse-system passes headstock, and its termination is arranged in the centre bore of chuck.
Honing lever matches with the endoporus of carriage, and described carriage is fixed on the lathe bed, and the spindle of boring bar case is connected on the screw body of boring machine mutually by the feed screw nut.
The utlity model has following advantage:
The size and dimension precision height that adopts the described boring machine of this patent cylinder inner bore to be carried out honing.Because every emery stick all is to cut by the surface that external force tightly is attached to endoporus during honing,, change geometry so can eliminate the not garden degree of endoporus.And the surface that super refined grinding wheel is a active force by spring is attached to endoporus cuts, and emery wheel can only be walked along the surface of endoporus, can not change the geometry of endoporus.
When adopting the described honing head honing of this patent, be the push rod that promotes honing head by hydraulic cylinder, the emery stick box opened, make several emery sticks be attached to surface of the work uniformly, finish the honing process by the relative motion of workpiece and honing head by ejector pin.Emery stick is made up of the grit of numerous irregular arrangement, each grit all is a cutting point, so the honing track that the honing track of emery stick leading portion in running and back segment produce can not repeat, thereby changed original track, form a kind of netted lines thereby eliminated the rotation problem of piston rod.
Through test, adopting the described boring machine of this patent is super smart more than 8～10 times to the efficient of cylinder inner bore honing, and the surface roughness height of endoporus, can reach Ra0.4-Ra0.2;
After boring machine has increased by a cover honing system, not only solved the rotation problem of hydraulic cylinder piston rod, improved the quality of product, and improved the utilization rate and the operating efficiency of deep hole boring machine, during use, after the cylinder inner bore deep hole finishes, borer is replaced with hone, can carries out honing, simple to operate, enforcement is easy and honing effect is good, is beneficial to and applies.
