The ball nuts ordered by the user are all ordered, and the load and the nut length are fixed and are difficult to change. A splittable single-circulation ball nut body is now provided.
The invention content is as follows:
the invention provides a spliced single-circulation ball nut body for solving the problems in the prior art.
The technical scheme adopted by the invention is as follows: the utility model provides a single circulation ball nut body that can splice, includes connecting block, packing ring and the nut body that is equipped with the reverser mounting hole, be equipped with two first mounting grooves on the outer circumferential wall of nut body at least, first mounting groove sets up along the axial direction of nut body, is equipped with two second mounting grooves on the outer circumferential wall of packing ring at least, and a plurality of nut body sets up side by side, sets up a packing ring between two adjacent nut bodies, first mounting groove link up with the second mounting groove mutually, and the connecting block is arranged in first mounting groove and second mounting groove, at the both ends threaded connection two bolts of connecting block to correspond two adjacent nut body fixed connection.
Furthermore, positioning boss parts are arranged on the end faces of two sides of the nut body, the outer diameter of each positioning boss part is matched with the inner diameter of the corresponding gasket, the axial length of each positioning boss part is 1/2 of the axial length of the corresponding gasket, and the positioning boss parts on the corresponding sides of the two adjacent nut bodies are clamped in the corresponding gaskets.
Further, threaded holes are symmetrically formed in two ends of the first mounting groove, the threaded holes are of blind hole structures, and two through holes are formed in two ends of the connecting block.
Further, the first mounting groove and the second mounting groove are both rectangular groove structures, and the connecting block is a rectangular block structure.
The invention has the following beneficial effects:
in the aspect of processing: the conventional ball nut can cause that the nut cannot be processed too long due to the length problem of the cutter bar, but the common cutter for the splicable nut can be used for processing the splicable nut completely, so that the processing cost is reduced, and due to the splicable property, if the number of nut circulation turns required by a user is complex, the nuts with different turns need to be designed in the conventional processing, the replicability of the splicable nut can meet the user requirement only by taking out the nuts with corresponding number, and the processing method is suitable for assembly line processing and saves the cost. And because the processing difficulty is low, the realization of interchangeability is simpler.
On the user side: the user can be according to oneself different kind operational environment, and different models assemble the nut by oneself. The user can increase and reduce the nut number by oneself, improves or reduces the load. The freedom and the debugging are increased.
In the aspect of products: can splice the nut and can realize processing the load that is difficult to reach, the nut of the same number of cycles moreover, the total length of the nut of concatenation can be shorter than whole nut, in accurate small-size instrument, has saved the inner space and has increased effective stroke, has more the advantage.
Description of the drawings:
FIG. 1 is a block diagram of the present invention.
Fig. 2 is a structural view of a nut body according to the present invention.
Fig. 3 is a view showing an installation structure between a nut body and a washer according to the present invention.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 3, the single-circulation ball nut body capable of being spliced according to the present invention comprises a nut body 1, a connecting block 2 and a washer 3, wherein a reverser mounting hole 10 is provided in a radial direction of a circumferential wall of the nut body 1.
At least two first mounting grooves 11 are formed in the outer circumferential wall of the nut body 1, the first mounting grooves 11 are arranged along the axial direction of the nut body 1, and at least two second mounting grooves 31 are formed in the outer circumferential wall of the washer 3. A plurality of nut body 1 is abreast and coaxial setting, sets up a packing ring 3 between two adjacent nut bodies 1, and first mounting groove 11 link up with second mounting groove 31 mutually, and in first mounting groove 11 and second mounting groove 31 were arranged in to connecting block 2, two bolts of both ends threaded connection at connecting block 2 to correspond two adjacent nut bodies 1 fixed connection.
In order to make the structure more stable, the positioning boss parts 12 are arranged on the two side end faces of the nut body 1, the outer diameter of the positioning boss part 12 is matched with the inner diameter of the gasket 3, the axial length of the positioning boss part 12 is 1/2 of the axial length of the gasket 3, and the positioning boss parts 12 on the corresponding sides on the two adjacent nut bodies 1 are clamped in the gasket 3.
Threaded holes 13 are symmetrically formed in two ends of the first mounting groove 11, the threaded holes 13 are of blind hole structures, and two through holes are formed in two ends of the connecting block 2. The screw passes through the through hole of the connecting block 2 and is screwed in the threaded hole 13 of the nut body 1.
The ball nut is designed into a circle of straight-tube-shaped ball nut, and two key grooves are processed on the outer ring and used for connecting a plurality of nut bodies.
When the screw pair is used in an environment requiring particularly high load, such as a gantry machining center, a designed single-cycle ball nut body pre-tightened by a gasket can be used. The nut capable of being pre-tightened by the gasket can provide larger pre-tightening force, so that the screw rod pair can keep the precision and improve the rigidity under the working environment with large load.
The invention has the following advantages:
in the aspect of processing: the conventional ball nut can cause that the nut cannot be processed too long due to the length problem of the cutter bar, but the common cutter for the splicable nut can be used for processing the splicable nut completely, so that the processing cost is reduced, and due to the splicable property, if the number of nut circulation turns required by a user is complex, the nuts with different turns need to be designed in the conventional processing, the replicability of the splicable nut can meet the user requirement only by taking out the nuts with corresponding number, and the processing method is suitable for assembly line processing and saves the cost. And because the processing difficulty is low, the realization of interchangeability is simpler.
On the user side: the user can be according to oneself different kind operational environment, and different models assemble the nut by oneself. The user can increase and reduce the nut number by oneself, improves or reduces the load. The freedom and the debugging are increased.
In the aspect of products: can splice the nut and can realize processing the load that is difficult to reach, the nut of the same number of cycles moreover, the total length of the nut of concatenation can be shorter than whole nut, in accurate small-size instrument, has saved the inner space and has increased effective stroke, has more the advantage.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
