Abstract
The invention discloses a precise screw adjusting assembly. The precise screw adjusting assembly comprises a locking part and a rotary knob part which are integrated. The outer side of the locking part is sleeved with a large-diameter fine thread fine-adjustment screw and a hexagonal nut which are integrated, and a fine thread fine-adjustment nut which is meshed with the fine-adjustment screw through fine threads is arranged outside the fine-adjustment screw. The locking part and a guiding rail installing base are interlocked through threads, and the fine-adjustment screw penetrates through a U-shaped base and is used for locking the fine-adjustment screw and the U-shaped base through the fine-adjustment nut. A concave cambered surface gasket and a convex cambered surface gasket which are matched with each other are arranged between the fine-adjustment screw and the guide rail installing base. According to the precise screw adjusting assembly, due to the combination of a large-diameter fine thread fine-adjustment bolt and the fine-adjustment nut, micron-level precision fine adjustment can be achieved; due to the cooperation of the concave cambered surface gasket and the convex cambered surface gasket, the precise screw adjusting assembly can self-adapt to the parallelism of guide rails and other parts so that self-adaptation levelness fine adjustment can be performed; thirdly, installing and adjusting are convenient, and required precision can be easily guaranteed.
Description
Technical field
The present invention relates to the precision screw adjusting part that the parts such as a kind of guide rail levelness for large-scale precision equipment carry out the adjustment of μ class precision.
Background technology
Large-scale precision machining equipment, it is also high to the required precision of guide rail, but because high accuracy guide rail is bulky, therefore the guide rail being obtained high precision by pure production and processing is very difficult, not only to process equipment requirement height very, and machining accuracy is difficult to ensure, have long processing time, processing cost high, in actual shipment and the large defect of assembling process difficulty.Therefore, can by changing traditional accurately machined mode, change fine setting into realize the mode of high accuracy processing, namely the trimming assembly of development of new is to realize high accuracy μ level fine setting guide rail or other being needed to the parts regulated, to reduce guide rail or other need the machining accuracy of adjustment member, thus cut down finished cost.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of precision screw adjusting part, regulating with the μ class precision realizing the parts such as large-scale precision machining equipment guide rail, effectively guaranteeing positioning and guiding and the machining accuracy of large-scale workpiece.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of precision screw adjusting part, comprises tight lock part and the knob of one, and be arranged with the thin thread fine setting screw rod of major diameter and the hex nut of one outside described tight lock part, described fine setting screw rod outside has the thin thread fine-tuning nut engaged by thin thread; Described tight lock part and described guide rails assembling seat are locked mutually by screw thread, and described fine setting screw rod and U-shaped pedestal are also locked by described fine-tuning nut through described U-shaped pedestal by described fine setting screw rod; The cancave cambered surface pad cooperatively interacted and convex globoidal pad is provided with between described fine setting screw rod and guide rails assembling seat.
Wherein, flat shim one and flat shim two is disposed with between described hex nut and knob.
Pass through technique scheme, precision screw adjusting part provided by the invention, by changing traditional mode premised on the machining accuracy improving the parts such as guide rail, instead by μ class precision fine setting mode to obtain high-precision effective adjustment, namely by the fine setting to the μ class precision of the component level such as guide rail or upright position of the fine adjustment screw assembly of μ class precision, the high-accuracy water Pingdu that effectively can realize the parts such as guide rail when the component processing required precisions such as guide rail are not high regulates, that is: the combination of the 1. thin thread trimming bolt of major diameter and fine-tuning nut, the fine setting of μ class precision can be realized, 2. the coordinating of cancave cambered surface pad and convex globoidal pad, can the parts such as self adaptation guide rail the depth of parallelism and carry out the fine setting of self adaptation levelness, 3. install and adjust is convenient, easily ensures precision prescribed.

In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the fine adjustment screw assembly sectional structure schematic diagram disclosed in the embodiment of the present invention.
Numeral in figure:
11. tight lock part 12. knobs 13. finely tune screw rod
14. hex nut 15. fine-tuning nut 16. cancave cambered surface pads
17. convex globoidal pad 18. flat shim 1 flat shims two
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
With reference to figure 1, precision screw adjusting part provided by the invention, comprise tight lock part 11 and the knob 12 of one, be arranged with major diameter thin thread fine setting screw rod 13 and the hex nut 14 of one outside tight lock part 11, fine setting screw rod 13 outside has the thin thread fine-tuning nut 15 engaged by thin thread; Tight lock part 11 and guide rails assembling seat 12 are locked mutually by screw thread, and fine setting screw rod 13 is passed U-shaped pedestal 11 and fine setting screw rod 13 and U-shaped pedestal 11 locked by fine-tuning nut 15; The cancave cambered surface pad 16 and convex globoidal pad 17 that cooperatively interact is provided with between fine setting screw rod 13 and guide rails assembling seat 12; Flat shim 1 and flat shim 2 19 is disposed with between hex nut 14 and knob 12.
Operation principle of the present invention:
When adopting fine adjustment screw assembly 15 to regulate, owing to have employed the cancave cambered surface pad 16 and convex globoidal pad 17 that cooperatively interact, parts to be regulated apply pressure to cancave cambered surface pad 16 and convex globoidal pad 17 under the effect of deadweight, thus coordinate with the self adaptation of convex globoidal pad 17 realize tentatively regulating by cancave cambered surface pad 16, coordinating then by major diameter thin thread fine setting screw rod 13 and fine-tuning nut 15, the fine setting treating adjustment member is realized while by precession or back-out hex nut 14, in adjustment process, cancave cambered surface pad 16 and convex globoidal pad 17 also can be finely tuned by synchronous self-adapting simultaneously, thus realize the high accuracy μ level fine setting of parts to be regulated, effectively ensure that levelness and the Workpiece Machining Accuracy of the parts such as guide rail.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of above-described embodiment, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
