Abstract
The utility model relates to a super-precision inner diameter rolling head for the accurate processing of the inner hole of a workpiece. The utility model is characterized in that on the screw thread in the middle part of the taper shank a regulating gear matched with the screw thread and a positioning gear sheathed on the screw thread are arranged, a guide key is arranged on the positioning gear, an outer sleeve with an inner gear is arranged on the positioning gear and the regulating gear, a thrust bearing and a connecting sleeve is arranged in the middle part of the taper shank, a taper body and a roller shelf is arranged on the front end of the taper shank, and a plurality of rollers are arranged on the roller shelf. The utility model has the advantages that the processing precision is high, after rolling, the roughness on the surface of the workpiece can be upgraded from Ra 12.5 to Ra 0.16, the hardness can be improved to 40 HV, and consequently the mechanical properties and the quality of the processing workpiece are increased.
Description
The utility model belongs to a kind of rolling device, the particularly a kind of accurately machined extra accuracy internal diameter of workpiece endoporus rolling head that is used for.
In the prior art, the high workpiece of this class endoporus required precision of cylinder, hydraulic cylinder and damper cylinder body normally adopts methods such as fraising, grinding out, honing or right boring to process.But the bore area precision of said method processing is difficult to the requirement that reaches higher, thereby the durability of cylinder body and be difficult to further raising service life.
The purpose of this utility model is the processing problems that solves high precision inner-pore, provides that a kind of process velocity is fast, precision is high, the extra accuracy internal diameter rolling head that versatility is good.
The utility model is achieved in that
It has a taper shank, be processed with screw thread and guiding keyway at the middle part of taper shank, associated adjustment gear is installed on the screw thread, adjusting gear is connected with Positioning Gear by jump ring, the feather key that matches with the strong groove of guiding on the taper shank is being installed on the Positioning Gear, on Positioning Gear and adjustment gear, outer sleeve is installed also, the front end of outer sleeve is equipped with gland, have the internal gear that and adjustment gear and Positioning Gear is meshed in the outer sleeve, adapter sleeve also is installed on taper shank, between adapter sleeve and the adjustment gear thrust bearing is housed; Front end at taper shank is equipped with cone, and the outside of cone is set with the roller frame that joins with adapter sleeve, and several rollers are housed on the roller frame.
Advantage of the present utility model is:
1, machining accuracy height, workpiece is after roll extrusion is rolling, its inner bore surface roughness can be brought up to more than the Ra0.16 from Ra12.5, and is as bright as a sixpence, and the internal diameter size unanimity, tolerance precise control strictness, simultaneously, workpiece is also had the effect of flow harden, it is fine and closely woven more hard that finished surface is organized, its hardness can improve 40HV, has improved the mechanical performance and the quality of processing work.
2, the front end of dog is provided with roller frame and cone, changes the relative position of roller frame and cone, can finely tune dog, changes the dog size, adjusts hole tolerance.
3, versatility is good, at car, mill, all can use on the lathe such as brill, boring, can replace operations such as right boring, mill, honing, hinge, scraping on some workpiece, and is convenient and simple for operation, the production efficiency height.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
As shown in the figure, the utility model has a taper shank 1, the rear end of taper shank 1 is a bullet, can be installed on the mohs tapered bore main shaft of lathe, the middle part of taper shank 1 is processed with screw thread and guiding keyway, associated adjustment gear 9 is installed on screw thread, adjusting gear 9 is connected with Positioning Gear 10 by jump ring 12, the width of adjusting gear 9 is greater than Positioning Gear 10, described Positioning Gear 10 is sleeved on the screw thread of taper shank 1, feather key 14 is installed on Positioning Gear 10, and feather key 14 can slide in the guiding keyway of taper shank 1, so Positioning Gear 10 can only endwisely slip along taper shank 1; On Positioning Gear 10 and adjustment gear 9 outer sleeve 13 is installed also, the front end of outer sleeve 13 is equipped with gland 11, and two internal gears that are meshed with adjustment gear 9 and Positioning Gear 10 are arranged in the outer sleeve 13; Adapter sleeve 5 also is installed on taper shank 1, between adapter sleeve 5 and the adjustment gear 9 thrust bearing 8 is housed, make adapter sleeve 5 and adjust between the gear 9 and can relatively rotate, in the rear end of adapter sleeve 5 jump ring 7 is housed, deviate from from gland 11 to avoid adapter sleeve 5, between jump ring 7 and gland 11, spring 6 is housed also,, guarantees that Positioning Gear 10 is meshed with internal gear on the outer sleeve 13 after adjustment so that outer sleeve 13 automatically resets; Front end at taper shank 1 is equipped with cone 2, be set with roller frame 4 in the outside of cone 2, roller frame 4 joins with adapter sleeve 5, on roller frame 4, be processed with several roller holes, roller 3 is housed in the roller holes, and according to the size of dog size, roller 3 can be provided with 3,4,6,8 or more, said roller holes is outer big in little, has guaranteed that roller 3 can not deviate from from roller frame 4.
During use, at first adjust the dog diameter according to the processing dimension of workpiece, being about to outer sleeve 13 moves backward, the Positioning Gear 10 and the internal gear of outer sleeve 13 are thrown off, at this moment, owing to adjust gear 9 broads, so still with outer sleeve 13 on internal gear segments engagement, rotary sleeve tube 13 is adjusted gear 9 and is rotated on the screw thread of taper shank 1 thereupon, and drives Positioning Gear 10, adapter sleeve 5 and roller frame 4 move on taper shank 1, when roller frame 4 moves, drive roller 3 and on cone 2, move, thereby change the dog diameter, after the dog size adjusting finishes, unclamp outer sleeve 13, outer sleeve 13 is to reach under the effect of spring 6, and its internal gear can mesh with Positioning Gear 10, with outer sleeve 13 lockings; And then with dog be installed in car, mill, on the mohs tapered bore main shaft of lathes such as brill, boring, dog rotates like this, workpiece is motionless to be processed; Also can be installed on the tailstock of lathe, dog is motionless, and workpiece rotates and processes; Withdraw from dog after rolling, at this moment, but the dog auto-necking can not damage surface to be machined.
