Description
Technical field
The utility model belongs to machine tools, particularly a kind of rolling head that the workpiece endoporus is processed of being used for.
Background technology
Processing method to cylinder inner bores such as cylinder, hydraulic cylinders in conventional art all is to adopt fraising, grinding out or right boring etc., and its machining accuracy is difficult to reach requirement.ZL94230112.9, extra accuracy endoporus rolling head patent disclosure a kind of endoporus rolling head, adopt it can improve machining accuracy, still, this rolling head complex structure is adjusted complex operation, machining accuracy has much room for improvement.
The content of utility model
In order to solve existing rolling head complex structure, unhandy problem proposes following technical scheme.A kind of high accuracy rolling head, it comprises that one is processed with screw thread 1.1 and guiding keyway 1.2 in the middle, the taper shank 1 of cone 6 is installed at its front end, its special character is that the adjustment gear ring 9 that matches with screw thread 1.1 is installed at the middle part of taper shank 1, be set with location gear ring 10 in the back of adjusting gear ring 9, in the gear ring 10 of location the feather key that cooperates with the keyway 1.2 that leads is installed, location gear ring 10 can move along guiding keyway (1.2), the back of location gear ring 10 is equipped with the setscrew nut 11 that matches with screw thread 1.1, the anterior inboard of adjusting gear ring 9 is spill, wherein installed thrust bearing 3 and roller frame 5, the tail end pocketed springs 4 of roller frame 5, the front end of roller frame 5 is equipped with some rollers 7, the front end outside of adjusting gear ring 9 is processed with screw thread, gland 8 links to each other with adjustment gear ring 9 by this screw thread, with thrust bearing 3, roller frame 5 and spring 4 are fixed on to be adjusted in the gear ring 9, the intermeshing teeth 2 of processing on the circumference of the opposite side of adjusting gear ring 9 and location gear ring 10.
Compared with the prior art, the utlity model has following advantage:
Owing to cancelled outer sleeve and internal gear, make simple in structurely, easy to operate, and improved machining accuracy.
Description of drawings
Fig. 1 is the structural representation of embodiment.
The specific embodiment
Narrate embodiment with reference to the accompanying drawings.
A kind of high accuracy rolling head, it comprises that one is processed with screw thread 1.1 and guiding keyway 1.2 in the middle, the taper shank 1 of cone 6 is installed at its front end, the adjustment gear ring 9 that matches with screw thread 1.1 is installed at the middle part of taper shank 1, be set with location gear ring 10 in the back of adjusting gear ring 9, in the gear ring 10 of location the feather key that cooperates with the keyway 1.2 that leads is installed, location gear ring 10 can move forward and backward along the guiding keyway, the back of location gear ring 10 is equipped with the setscrew nut 11 that matches with screw thread 1.1, the anterior inboard of adjusting gear ring 9 is spill, installed thrust bearing 3 and be the roller frame 5 of ladder bushing shape wherein, its rear end is thicker, external diameter is greater than the internal orifice dimension of gland 8, tail end pocketed springs 4 at roller frame 5, the front end of roller frame 5 is processed with several roller holes, roller 7 is housed in it, according to the size of dog size, roller 7 can be set to 4,68 or more.The front end outside of adjusting gear ring 9 is processed with screw thread, and gland 8 links to each other with adjustment gear ring 9 by this screw thread, thrust bearing 3, roller frame 5 and spring 4 is fixed on adjusts in the gear ring 9.All be processed into tubular at the opposite side of adjusting gear ring 9 and location gear ring 10, be processed with some intermeshing teeth 2 on its circumference.Be marked with the adjustment scale in the teeth of adjusting gear ring 9, be marked with " 0 " line location scale in the teeth of locating gear ring 10.
During use, adjust the dog diameter according to the processing dimension of workpiece, promptly rotate, unclamp setscrew nut 11, pull back location gear ring 10, location gear ring 10 and adjustment gear ring 9 are broken away from, gear ring 9 is adjusted in rotation then, drives roller frame 5 and moves forward and backward.Because cone 6 has certain tapering, when roller frame 5 moves, drive roller 7 and on cone 6, move, thereby change the dog diameter.The dog size adjusting will be located gear ring 10 and push away forward after being finished, and the teeth 2 of location gear ring 10 and adjustment gear ring 9 are meshed, and setscrew nut 11 be rotated locking positioning gear ring 10 and adjustment gear ring 9 forward again.Owing to be marked with the adjustment scale in the teeth of adjusting gear ring 9, be marked with " 0 " line location scale in the teeth of locating gear ring 10, therefore can make things convenient for, accurately adjust the dog size.
