Description
Technical field
The utility model relates to mechanical inner bore machining device field, is specially a kind of internal rolling cutter.
Background technology
Traditional internal rolling cutter after adjustment rolling quantity, then is locked by lock nut, but in this adjustment process, regulating sleeve easily walks, and causes the rolling quantity of adjustment inaccurate.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of regulating sleeve to be not easy to walk, degree of regulation internal rolling cutter accurately.
For achieving the above object, the utility model provides following technical scheme: a kind of internal rolling cutter, comprise mandrel, the middle part of described mandrel offers annular groove, the middle part of mandrel is arranged with regulating sleeve and the tightening nuts with regulating sleeve adaptation, described regulating sleeve is provided with the annular lug with annular groove adaptation, described mandrel be axially provided with some deep-slotted chip breakers, deep-slotted chip breaker slidably connects the first steel ball with deep-slotted chip breaker adaptation, blind hole is provided with in described regulating sleeve, blind hole internal fixtion has the first spring, first spring and the first steel ball are slidably connected, described core sleeve is provided with the second spring, the first baffle plate for fixing the second both ends of the spring and second baffle is provided with between described mandrel and regulating sleeve, described regulating sleeve is connected with the first back-up ring, mandrel is connected with the second back-up ring, the second steel ball is covered with between first back-up ring and the second back-up ring.
Further, the groove depth maximum of described deep-slotted chip breaker and the diameter ratio of the first steel ball are 1:10-1:8.
Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that the utility model provides is brought: 1. the utility model to be conflicted the first steel ball by the first spring, after accurate adjustment rolling quantity, first steel ball dropping place is in deep-slotted chip breaker, regulating sleeve is made to be not easy to walk, now, then lock tightening nuts, effectively ensure that the precision of measurement.2. the utility model is by the design of the second steel ball, the first ring washer and the second back-up ring, makes regulating sleeve in the process regulated, there will not be the phenomenon of clamping stagnation.
Accompanying drawing explanation
Fig. 1 is: cross-sectional schematic of the present utility model.
Fig. 2 is: the partial schematic diagram of mandrel.
Detailed description of the invention
With reference to Fig. 1-Fig. 2, the utility model is described further.
A kind of internal rolling cutter, comprise mandrel 1, the middle part of described mandrel 1 offers annular groove 2, the middle part of mandrel 1 is arranged with regulating sleeve 3 and the tightening nuts 8 with regulating sleeve 3 adaptation, described regulating sleeve 3 is provided with the annular lug 5 with annular groove 2 adaptation, described mandrel 1 be axially provided with some deep-slotted chip breakers 6, deep-slotted chip breaker 6 slidably connects the first steel ball 7 with deep-slotted chip breaker 6 adaptation, blind hole 31 is provided with in described regulating sleeve 3, blind hole 31 internal fixtion has the first spring 32, first spring 32 and the first steel ball 7 are slidably connected, described mandrel 1 is arranged with the second spring 11, the first baffle plate 12 for fixing the second spring 11 two ends and second baffle 13 is provided with between described mandrel 1 and regulating sleeve 3, described regulating sleeve 3 is connected with the first back-up ring 33, mandrel 1 is connected with the second back-up ring 34, the second steel ball 35 is covered with between first back-up ring 33 and the second back-up ring 34.
To be conflicted the first steel ball 7 by the first spring 32, accurate regulate rolling quantity after, the first steel ball 7 dropping place, in deep-slotted chip breaker 6, makes regulating sleeve 3 be not easy to walk, and now, then locks tightening nuts 8, effectively ensure that the precision of measurement.
By the design of the second steel ball 35, first ring washer 33 and the second back-up ring 34, the second steel ball 35 effectively decreases frictional force during adjustment, makes regulating sleeve 3 in the process regulated, there will not be the phenomenon of clamping stagnation.
Further, the groove depth maximum of described deep-slotted chip breaker 6 and the diameter ratio of the first steel ball 7 are 1:10-1:8.
The groove depth maximum of deep-slotted chip breaker 6 and the diameter ratio of the first steel ball 7 can not be excessive, otherwise, when rotating regulating sleeve 3, steel ball is caused to be not easy from deep-slotted chip breaker 6 out, easily occur that the phenomenon of clamping stagnation occurs, but, the groove depth maximum of deep-slotted chip breaker 6 and the diameter ratio of the first steel ball 7 can not be too small, otherwise, cause the poor effect of deep-slotted chip breaker 6 positioning ball, the phenomenon that causes steel ball easily to occur walking occurs, as preferably: the groove depth maximum of deep-slotted chip breaker 6 and the diameter ratio of the first steel ball 7 are set to 1:10-1:8.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
