Abstract
The utility model discloses a screw plate which comprises a static plate and a moving plate; both sides of short sides of the rectangle of the static plate are provided with feeding angles and discharge angles of 1 to 3 degrees; the working surfaces of the static plate and the moving plate are provided with a plurality of parallel tooth treads, and the tooth treads are deployed in a wave shape along the length direction; and the working surfaces of the static plate and the moving plate are uniformly provided with a plurality of strip-shaped grooves along the length direction and the angles formed by the strip-shaped grooves and the lateral sides of the static plate and the moving plate are 55 to 75 degrees. In the scheme, the tooth threads are deployed in a continuous circular arc shape along the height direction. In the screw plate, because the working surfaces of the static plate and the moving plate are provided with a plurality of strip-shaped grooves and the angles formed by the strip-shaped grooves and the lateral sides of the static plate and the moving plate are 55 to 75 degrees, the rolled screw threads are provided with spiral prism surfaces along the axial direction of the cylindrical surface, so that the self-locking performance of the screws is higher.
Description
Technical field
The utility model relates to the screw shaping jig, is specifically related to the screw screw plate.
Background technology
Screw is a kind of securing member commonly used, generally processes by screw plate.Tooth line on the existing screw plate is rectilinear, and therefore the screw that processes is columned screw thread, and the locking of such screw is not very stable.Development along with modern industrial technology, list at a high speed in war industry, space flight, high-speed rail transportation, magnetic suspension, some are important automobile, boats and ships, engineering machinery, power station power-equipment, bridge construction, steel construction, household electrical appliance, industrial electrical equipment etc. (vibrations are especially arranged) occasion requires very highly to the self-locking performance of screw, the high-strength screw that produced in conventional processes goes out can not be competent at again.
The utility model content
Technical problem to be solved in the utility model is to solve the not high problem of screw self-locking performance that screw plate processes.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of screw screw plate, comprise quiet plate and moving plate, the working face of quiet plate and moving plate is provided with many tooth lines that be arranged in parallel, the tooth line is the 1-7 degree with the side angle of quiet plate or moving plate respectively, and the tooth line is wavy layout along its length, and being laid with a plurality of strip grooves and strip groove on the working face of quiet plate and moving plate along its length is the 55-75 degree with the angle of the side of quiet plate or moving plate respectively.
In the such scheme, the tooth line is continuous arc along short transverse and arranges.
The utility model, because it is the 55-75 degree with the angle of the side of quiet plate or moving plate respectively that the working face of quiet plate and moving plate is provided with a plurality of strip grooves and strip groove, the screw thread that rubs axially has a spirality prismatic surface along the face of cylinder, so the self-locking performance of screw is higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the working face schematic diagram of quiet plate of the utility model or moving plate.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1 and Figure 2, the utility model comprises quiet plate 2 and moving plate 1, moving plate 1 and quiet plate 2 all is rectangular-shaped and there are 1-3 ° angle of feed and discharging angle in the minor face both sides, the working face of quiet plate 2 and moving plate 1 is provided with many tooth lines 3 that be arranged in parallel, tooth line 3 is the 1-7 degree with the angle β of the side of quiet plate 2 or moving plate 1 respectively, and tooth line 3 is wavy layout along its length, and tooth line 3 is continuous arc along short transverse to be arranged, is semicircle in the present embodiment.Be laid with a plurality of strip grooves 4 on the working face of quiet plate 2 and moving plate 1 along its length, these strip grooves 4 are parallel to each other and are the 55-75 degree with the side angle α of quiet plate 2 or moving plate 1 respectively, diameter according to screw, by adjusting the spacing of adjacent strip groove 4, can rub the screw cylinder screw of different prismatic forms, as quadrangular face, six prismatic surfaces etc.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
Claims (2)
1. screw screw plate, comprise quiet plate and moving plate, the working face that it is characterized in that quiet plate and moving plate is provided with many tooth lines that be arranged in parallel, the tooth line is the 1-7 degree with the side angle of quiet plate or moving plate respectively, and the tooth line is wavy layout along its length, and being laid with a plurality of strip grooves and strip groove on the working face of quiet plate and moving plate along its length is the 55-75 degree with the angle of the side of quiet plate or moving plate respectively.
