Abstract
The utility model discloses a precision and synchronous heavy-load lifting trapezoidal screw rod and nut pair group which adopts the following technical scheme: the screw rod and nut pair group comprises a workgroup consisting of 4 to 256 (any number within the range) screw rod and nut pairs; the sizes and specifications of the screw rod and nut pairs in the workgroup are the same; the screw rod and nut pairs in the workgroup carry out lifting synchronously; each screw rod and nut pair is provided with a working nut and a safety nut; the working nuts are fixedly connected with a mechanical lifting table; and the safety nuts and the working nuts are connected by driving rods and driving pins. The precision and synchronous heavy-load lifting trapezoidal screw rod and nut pair group meets the requirement of precision and synchronous lifting of the whole workgroup consisting of a plurality of trapezoidal screw rod and nut pairs; the force bearing of each pair is uniform, and the friction is mild; the safety nuts carry out lifting together with the working nuts; when internal threads of the working nuts are damaged, the safety nuts can support and protect a mechanical lifting mechanism from being damaged through force bearing.
Description
Technical field
The utility model relates to a kind of transmitting assemblies, relates in particular to the synchronous heavily loaded lifting trapezoidal screw of a kind of precision, pair of nut group.
Background technique
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 MANUFACTURER is produced 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 frictional force are big.
Summary of the invention
The utility model is at 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 jam nut, described work nut is fixedlyed connected with the mechanical elevating platform, and described jam nut is connected with drive pin by driveshaft with the work nut.
Concrete characteristics of the present utility model also have, and all leading screws in the group are by a motor driving or organize each interior leading screw respectively by a motor single driving.
The beneficial effect of this programme can learn according to the narration to such scheme, and the utility model 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 frictional force is little; Jam nut is followed one lifting of work nut, is not damaged by stressed overfill protection mechanical elevator of jam nut structure when the work nut inner thread damages.
Description of drawings
Fig. 1, Fig. 2 are the structural representation of the utility model embodiment.
Fig. 3 is the structural representation of single leading screw, pair of nut.
Among the figure, 1, leading screw, 2, the work nut, 3, jam nut, 4, driveshaft, 5, drive pin.
Embodiment
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by an embodiment.
As shown in the figure, the utility model 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 jam nut 3, described work nut 2 is fixedlyed connected with the mechanical elevating platform, described jam nut 3 is connected with drive pin 5 by driveshaft 4 with work nut 2, fixedly connected with work nut 2 in the upper end of driveshaft 4, the lower end is connected with jam nut 3 by drive pin 5.As shown in Figure 2, all leading screws in the group are by a motor driving.Perhaps as shown in Figure 1, each leading screw in the group is respectively by a motor single driving.
The utility model can pass through or adopt existing techniques in realizing without the technical characteristics of describing; do not repeat them here; certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model 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 utility model also should belong to protection domain of the present utility model.
