Abstract
The utility model provides a square flange nut structure lead screw belongs to mechanical technical field. The nut mounting flange solves the problems that after the nut mounting flange of the existing nut screw rod is lack of precision of parts matched with the nut mounting flange, the nut mounting flange needs to be subjected to repeated match grinding to be corrected and can be mounted, and therefore maintenance is inconvenient and operation is inconvenient. The square flange nut structure screw rod is provided with a nut mounting flange connected with a part, the nut mounting flange is provided with a plurality of long groove type counter bores, each long groove type counter bore is formed by axially penetrating, and the nut mounting flange is of a square structure. The utility model has the advantages of need not to match and grind nut mounting flange, realize increasing efficiency quick maintenance and maintenance.
Description
Technical Field
The utility model belongs to the technical field of machinery, a nut lead screw is related to, in particular to square flange nut structure lead screw.
Background
The nut screw rod is a mechanical transmission product for converting rotary motion into linear motion.
The nut mounting flange of the conventional nut screw rod on the market adopts the design of circular shape, incomplete circular shape or double-incomplete circular shape, for example, as the patent documents with the patent number of '202022922569.7' and the patent name of 'a nut screw rod driving mechanism' disclosed in China, in the attached drawings of the patent, the nut mounting flange of the nut screw rod is easily found to be in double-incomplete circular shape design, a plurality of countersunk circular holes are formed in the flange of the double-incomplete circular structure, and the countersunk circular holes are used for connecting parts matched with the nut screw rod.
However, as is well known, when the precision of the matched part is lost, the part needs to be reground and scraped and then assembled, and the problem of reduction of the assembly height of the part occurs at this time, so that after the conventional screw rod is reassembled, the nut mounting flange matched with the conventional screw rod needs to be reground for many times to be corrected and installed, and the problems of inconvenient assembly, inconvenient maintenance, inconvenient operation and the like are caused.
Disclosure of Invention
The utility model aims at the above-mentioned problem that exists among the prior art, provide one kind and need not to match and grind nut mounting flange, realize the square flange nut structure lead screw of increase quick maintenance and maintenance.
The purpose of the utility model can be realized by the following technical proposal: the square flange nut structure screw rod is characterized in that a nut mounting flange connected with a part is arranged on the screw rod, a plurality of long groove type counter bores are formed in the nut mounting flange, each long groove type counter bore is formed by axially penetrating and forming, and the nut mounting flange is of a square structure.
In the square flange nut structure screw rod, the long groove type countersunk head hole is provided with a countersunk head screw for connecting parts.
In the square flange nut structure screw rod, four corners of the square nut mounting flange are respectively provided with a chamfer.
Compared with the prior art, the flange nut structure screw rod has the advantages that the nut mounting flange does not need to be ground, the efficiency is increased, the quick maintenance and the maintenance are realized, and the convenience in assembly and operation is further realized.
Drawings
Fig. 1 is a schematic perspective view of a screw rod with the flange nut structure.
Fig. 2 is a front view of a nut mounting flange.
In the figure, 1, a screw rod; 2. a nut mounting flange; 3. a slotted counter sink; 4. and (6) chamfering.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, in the flange-nut structured lead screw, a nut mounting flange 2 connected with a part is arranged on the lead screw 1, a plurality of elongated groove type countersunk holes 3 are formed in the nut mounting flange 2, each elongated groove type countersunk hole 3 is formed by axially penetrating, the nut mounting flange 2 is of a square structure, countersunk screws used for connecting the part are arranged in the elongated groove type countersunk holes 3, and chamfers 4 are arranged at four corners of the square nut mounting flange 2.
After the parts are ground and scrapped again under the condition of accuracy loss, the assembly height of the parts can be reduced, the height of the mounting positions of the nut mounting flanges 2 is adjusted through the elongated slot type countersunk holes 3, and the nut mounting flanges are locked through countersunk screws after the adjustment is finished; therefore, the nut mounting flange 2 does not need to be matched and ground, and the effects of synergy and quick maintenance are achieved.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
Although the terms lead screw 1, nut mounting flange 2, slotted counter bore 3, chamfer 4, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.
Claims (3)
