Abstract
The invention discloses a method for machining a threaded rod through a lathe. The method includes the steps that step 1, a three-jaw chuck is fixed to a cone-shaped die shank; step 2, a section of circular truncated cone is turned at one end of the threaded rod to be machined; step 3, a threading die is installed on a lathe head chuck, the circular truncated cone section of the threaded rod to be machined is clamped through the three-jaw chuck, the other end of the threaded rod to be machined is chamfered and then placed on a mouth of the threading die, the lathe is started, a tailstock hand shank of the lathe is shaken to enable the threaded rod to be machined to enter the threading die, at the moment, under the action of rotation of threading die screw threads, the threaded rod to be machined automatically penetrates through the threading die and enters a hollow main shaft of the lathe, and then the threaded rod machining is completed. The method for machining the threaded rod through the lathe has the advantages of solving the problem that a threaded rod with the diameter smaller than 50mm and the length larger than 1000mm is difficult to machine, according to the method, the maximum machining length of the threaded rod is the lathe bed length of the lathe, the threaded rod is not stressed by radial force in the thread machining process, and therefore precision and smooth finish of the threaded rod machining are greatly improved.
Description
Technical field
The present invention relates to the lathe processing method, especially relate to the method for utilizing lathe processing screw rod.
Background technology
It is to carry out turning by threading tool to machine that tradition is utilized the method for lathe processing screw rod, but, for elongate threaded screw, (diameter is less than 50mm, length is greater than 1000mm) processing, its difficulty is larger, tracing it to its cause, to be mainly threading tool very easily cause the distortion of screw rod in the radial load of adjusting detaining car to produce in cutting process, makes turning screw rod fineness and precision out all can't guarantee, percent defective is higher.
Summary of the invention
The object of the invention is to provide a kind of method of utilizing lathe processing screw rod.
For achieving the above object, the present invention takes following technical proposals:
The method of utilizing lathe processing screw rod of the present invention, comprise the steps:
The first step, scroll chuck is fixed on conical die shank, by described conical die shank, described scroll chuck is arranged on tail stock;
Second step, at end turning one a pitch circle platform of screw rod to be processed, the diameter of described round platform is less than Bottom of Thread diameter to be processed, the length of round platform is greater than the clamping length of screw die thickness+described scroll chuck;
The 3rd step, by described screw die, by die sleeve, be arranged on the head of a bed chuck of lathe, the round platform section of the described screw rod to be processed of scroll chuck clamping on tail stock, be put into screw die mouth place after the other end chamfering of screw rod to be processed, then start lathe, shaking the tail stock handle enters in screw die screw rod to be processed, now screw rod to be processed automatically enters in the lathe hollow spindle through screw die under the turning effort of screw die screw thread, after the round platform section of screw rod to be processed enters in screw die, because round platform section diameter is less than the root diameter of screw thread to be processed, therefore tail stock stops automatically, so far screw rod machines.
The diameter of described round platform is less than Bottom of Thread diameter 1-2mm to be processed, the clamping length that the length of round platform is twice screw die thickness+described scroll chuck.
The invention has the advantages that and solved that diameter is less than 50mm, length is greater than the large problem of 1000mm screw rod difficulty of processing.According to the inventive method, the lathe bed length that the screw rod maximum machining length is lathe, the screw thread process is not subject to the effect of radial load, has therefore greatly improved screw rod precision and the fineness processed.Simultaneously, processing method of the present invention is simple and reliable, and easy operating is lower to operator's specification requirement.
The accompanying drawing explanation
Fig. 1 is the schematic diagram according to the inventive method processing screw rod.
Fig. 2 is the structural representation of scroll chuck of the present invention.
Fig. 3 is the assembly drawing after scroll chuck of the present invention is installed on conical die shank.
The specific embodiment
As shown in Figure 1, 2, 3, the method for utilizing lathe processing screw rod of the present invention, according to following step, carry out:
The first step, scroll chuck 1 is fixed on conical die shank 2, by described conical die shank 2, described scroll chuck 1 is arranged on tail stock 3;
Second step, in end turning one a pitch circle platform section 5 of screw rod 4 to be processed, the diameter of described round platform section 5 is less than Bottom of Thread diameter 1mm to be processed, the clamping length that the length of round platform section 5 is twice screw die thickness+described scroll chuck 1;
The 3rd step, by described screw die, by die sleeve 6, be arranged on the head of a bed chuck 8 of lathe 7, the round platform section 5 of the described screw rod 4 to be processed of scroll chuck 1 clamping on tail stock 3, be put into screw die mouth place after the other end chamfering of screw rod 4 to be processed, then start lathe 7, shaking tail stock handle 9 enters in screw die screw rod 4 to be processed, now screw rod 4 to be processed automatically enters in lathe hollow spindle 10 through screw die under the turning effort of screw die screw thread, after the round platform section 5 of screw rod 4 to be processed enters in screw die, because round platform section 5 diameters are less than the root diameter of screw thread to be processed, therefore tail stock 3 stops automatically, so far screw rod machines.
Claims (2)
1. a method of utilizing lathe processing screw rod, is characterized in that: comprise the steps:
The first step, scroll chuck is fixed on conical die shank, by described conical die shank, described scroll chuck is arranged on tail stock;
Second step, at end turning one a pitch circle platform of screw rod to be processed, the diameter of described round platform is less than Bottom of Thread diameter to be processed, the length of round platform is greater than the clamping length of screw die thickness+described scroll chuck;
The 3rd step, by described screw die, by die sleeve, be arranged on the head of a bed chuck of lathe, the round platform section of the described screw rod to be processed of scroll chuck clamping on tail stock, be put into screw die mouth place after the other end chamfering of screw rod to be processed, then start lathe, shaking the tail stock handle enters in screw die screw rod to be processed, now screw rod to be processed automatically enters in the lathe hollow spindle through screw die under the turning effort of screw die screw thread, after the round platform section of screw rod to be processed enters in screw die, because round platform section diameter is less than the root diameter of screw thread to be processed, therefore tail stock stops automatically, so far screw rod machines.
