Abstract
The invention discloses a trapezoidal lead screw-nut pair set which can be subjected to precisely-synchronous heavy-load lifting. The technical scheme in the invention is as follows: the trapezoidal lead screw-nut pair set comprises a working-set consisting of 4-256 lead screw-nut pairs, and in the working-set, the sizes and specifications of the lead screw-nut pairs are same; the lead screw-nut pairs in the working-set are lifted synchronously, and each lead screw-nut pair is provided with a working nut and a safety nut,; and the working nut is fixedly connected with a mechanical lift table, and the safety nut and the working nut are connected with a drive pin by a drive rod. The trapezoidal lead screw-nut pair set disclosed by the invention has the advantages that the effect that a whole set consisting of a plurality of lead screw-nut pairs is subjected to precisely-synchronous lifting can be achieved, and each lead screw-nut pair is uniform in stress and small in frictional force; and because the safety nut and the working nut are lifted synchronously, when the internal thread of the working nut is damaged, the safety nut is stressed and supported so as to prevent a mechanical lifting mechanism from being damaged.
Description
Technical field
The present invention relates to a kind of transmission component, relate in particular to the synchronous heavily loaded lifting trapezoidal screw of a kind of precision, pair of nut group.
Background technology
Fast development along with domestic motor-car cause, the fast development of advanced stone machining equipment, heavily loaded lifting trapezoidal screw, pair of nut group that great special 8 marshallings of country, 16 marshalling motor car inspection and repair lines use are the critical components of the whole accurate synchronization lifting of motor car inspection and repair bundle of lines motor-car, and the left and right height that revolves lifting trapezoidal screw, pair of nut group synchronization accuracy that advanced stone machining equipment uses directly influences stone machining equipment performance, life-span.Above-mentioned mechanical elevating realizes that by how secondary heavily loaded lifting trapezoidal screw, pair of nut synchronization lifting together precision becomes mechanical key synchronously when guaranteeing every group of trapezoidal screw, pair of nut lifting.Trapezoidal screw, nut that present domestic leading screw maker produces are not protected synchronously, the 2 secondary synchronous because of can only protect by equipment precision, material restriction of synchronous requirement arranged, and synchronization accuracy are low, discontinuity during every subtask, and leading screw, nut friction force are big.
Summary of the invention
The present invention be directed to the existing in prior technology shortcoming, and the synchronous heavily loaded lifting trapezoidal screw of a kind of precision, pair of nut group are provided, it forms a working group by any amount leading screw, pair of nut in the secondary scope of 4 pairs to 256, guarantees this cocainine thick stick, pair of nut precision synchronously.
This reality is novel to be realized by following technical measures: the synchronous heavily loaded lifting trapezoidal screw of a kind of precision, pair of nut group, it comprises any amount leading screw in the secondary scope of 4 pairs to 256, working group of pair of nut composition, leading screw, pair of nut dimensions in the group are identical, leading screw, pair of nut synchronization lifting in the group, each leading screw, pair of nut all have work nut and safety nut, described work nut is captiveed joint with the mechanical elevating platform, and described safety nut is connected with drive pin by drive spindle with the work nut.
Concrete characteristics of the present invention also have, and all leading screws in the group are by a motor-driven or organize each interior leading screw respectively by a motor independent drive.
The beneficial effect of this programme can learn according to the narration to such scheme, and the present invention has satisfied the synchronously accurate of whole group one lifting that how secondary trapezoidal screw, pair of nut form, and every pair is stressed evenly, and friction force is little; Safety nut is followed one lifting of work nut, is not damaged by stressed overfill protection mechanical elevator of safety nut structure when the work nut inner thread damages.
Description of drawings
Fig. 1, Fig. 2 are the structural representation of the specific embodiment of the invention.
Fig. 3 is the structural representation of single leading screw, pair of nut.
Among the figure, 1, leading screw, 2, the work nut, 3, safety nut, 4, drive spindle, 5, drive pin.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by a specific embodiment.
As shown in the figure, the present invention is the synchronous heavily loaded lifting trapezoidal screw of a kind of precision, the pair of nut group, it comprises any amount leading screw in the secondary scope of 4 pairs to 256, pair of nut is formed a working group, leading screw in the group, the pair of nut dimensions is identical, leading screw in the group, the pair of nut synchronization lifting, each leading screw, pair of nut all has work nut 2 and safety nut 3, described work nut 2 is captiveed joint with the mechanical elevating platform, described safety nut 3 is connected with drive pin 5 by drive spindle 4 with work nut 2, captive joint with work nut 2 in the upper end of drive spindle 4, the lower end is connected with safety nut 3 by drive pin 5.As shown in Figure 2, all leading screws in the group are by a motor-driven.Perhaps as shown in Figure 1, each leading screw in the group is respectively by a motor independent drive.
The present invention can pass through or adopt existing techniques in realizing without the technical characterictic of describing; do not repeat them here; certainly; above-mentioned explanation is not to be limitation of the present invention; the present invention also is not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
