Abstract
The utility model discloses a pressing tool for novel screw threads. The slope of a tooth crest arranged on the cutting part of the utility model forms an included angle with the parallel line of an axial cord, the included angle ranges from 25 DEG to 35 DEG, and the slope of the tooth crest can be arranged on a reverse direction. By the application of the utility model, a nut which can be prevented from being lost due to vibration can be produced.
Description
The utility model relates to technical field of fastening.A kind of machining tool of novel screw thread specifically.
When the nut of common standard screw thread and screw rod cooperate, the in fact just single face contact of the tooth form of internal and external threads, the big portion of the load during screw-threaded coupling concentrates on the first and second circle screw threads of nut.Under the vibration situation, locking nut commonly used can lose 70% coupling mechanism force.
The purpose of this utility model provides a kind of can the cooperation with standard external, and can overcome the machining tool because of the loosening screw thread of vibration.This new type nut has obtained Chinese patent, and the patent No. is: 95213081.1.
Technical solution of the present utility model is: the angle that the tooth top inclined-plane on the machining tool blade of this novel screw chasing or extruding and the parallel lines of axis form is 25 °～35 °.The tooth top inclined-plane can process the nut that difference is subjected to force direction at two rightabout machining tools.
Through evidence, use the new type nut of the machining tool production of this novel screw thread in whole vibration test, can keep coupling mechanism force.And the coupling mechanism force of standard nut can completely lose, and torque take-up nut commonly used will lose 70% coupling mechanism force.Test also shows, when standard nut connects, have 50%～60% load to concentrate on the screw threads of first and second circles, and the load on the new type nut be evenly distribution, thereby improved the fatigue strength of screw thread.
Below in conjunction with accompanying drawing the present invention is further explained:
Fig. 1 is the tooth type structures schematic diagram of embodiment 1.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the tooth type structures schematic diagram of embodiment 2.
Fig. 4 is the tooth type structures schematic diagram of embodiment 3.
Fig. 5 is the tooth type structures schematic diagram of embodiment 4.
Fig. 6 is the tooth type structures schematic diagram of embodiment 5.
Embodiment 1: the tooth top inclined-plane 1 among Fig. 1 is 30 ° with axis angle that parallel lines form.
As can be known from Fig. 2, the utility model is divided into shank 2 and blade 3.
Embodiment 2: the direction at 1 place, tooth top inclined-plane is opposite with embodiment 1 as can be known from Fig. 3, is used for producing the nut that is subjected to force direction and embodiment 1 opposite.
Embodiment 3: as can be known from Fig. 4, tooth top inclined-plane 1 is the circular arc type conical surface that and axis parallel lines are 25 °～35 ° of angles.
Embodiment 4: as can be known from Fig. 5, tooth top inclined-plane 1 is the conical surfaces 25 °～35 ° of angles, two different angles by one with the axis parallel lines and is formed.
Embodiment 5: as can be known from Fig. 6, when pitch≤0.7mm, thread tooth type is a sawtooth pattern.
