Abstract
The invention discloses a machining method capable of avoiding making burrs on the spherical end face of a screw. When a screw with a spherical end face is machined, the threads and spherical end face of the screw with the spherical end face are machined by the conventional method first, the diameter of the circle at the jointed part of the spherical end face and the end part of the screw is controlled to be 0.3 to 0.5 millimeters smaller than the diameter of the thread root part of the screw, a scalene cone is formed between the circle on the jointed part of the spherical end face and the end part of the screw and threads on the end part of the screw, the included angle between the scalene cone and the vertical line of the screw is formed into 30 to 45 DEG C, and thus, after the screw is machined, the size consistency of the screw can be well kept, the workload of subsequent working procedures is reduced, the deformation at the end face of the screw is relieved, large burrs are prevented from being formed on the end part of the screw, and the integrity of the spherical end face of the screw is protected.
Description
Technical field
The present invention relates to a kind of processing method of avoiding screw rod spherical end surface frizzled feather thorn, belong to the screw-rod manufacturing technology field.
Background technology
Since mechanical industry was come out, what the connected mode between various frame for movements was effectively the easiest was exactly to be threaded, and was widely used invariably like industries such as traffic (railway, bridge), transportation (aircraft, tank, automobile), the energy.But in the prior art; Process general thread part particularly during the screw rod part; Generally adopt methods such as rolling, car system to process, the screw rod end face after processing all can produce burr, makes its end face produce distortion; Thereby influence the processing of accessory size and subsequent handling, increased difficulty of processing.Therefore, existing screw machining method still is not ideal enough.
Summary of the invention
The objective of the invention is: provide a kind of and can reduce the screw rod face deformation and avoid the end to produce the processing method of avoiding screw rod spherical end surface frizzled feather thorn of big burr, thereby overcome the deficiency of prior art.
The present invention is achieved in that when processing has the screw rod of spherical end surface; Adopt conventional method to process screw flight earlier with spherical end surface; The radius of the spherical end surface of this screw rod end according to the needs that use according to conventional method value and making; Diameter of a circle with spherical end surface and junction, screw rod end is controlled at less than 0.3～0.5 millimeter of screw flight root diameter (RD) simultaneously; And between the end thread of the circle of spherical end surface and junction, screw rod end and screw rod, make a scalene cone; Angle between scalene cone and the screw rod vertical line is made into 30 °～45 ° angle; Can make like this screw rod can well guarantee screw size after machining uniformity with alleviate the workload of subsequent handling, and reduce the distortion of screw rod end and avoid the screw rod end to produce big burr, protect the integrality of the spherical end surface of screw rod simultaneously.
When being made into 30 ° angle, adopt the angle between scalene cone and the screw rod vertical line method of rolling to make; When being made into 45 ° angle, adopt the angle between scalene cone and the screw rod vertical line method of car system to make.
Owing to adopted technique scheme; The present invention is through changing the spherical end surface structure of screw rod part; Thereby make this part after screw thread processing, can reduce the end distortion and avoid producing big burr, guaranteed the integrality of spherical end surface simultaneously; And uniformity that more can guarantee accessory size and the workload that alleviates subsequent handling, greatly reduce difficulty of processing.Therefore, the present invention compared with prior art, the present invention not only has and can reduce the screw rod face deformation and avoid the end to produce the advantage of big burr, but also the spherical end surface screw rod quality advantages of higher that has handling ease and process.
Description of drawings
Fig. 1 is the structural representation of the screw rod processed of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is done further detailed description.
Embodiments of the invention: when processing has the screw rod 1 of spherical end surface; Adopt conventional method to process the screw thread of screw rod 1 earlier with spherical end surface; Its thread size can be confirmed according to the needs that use; With the radius of the spherical end surface 2 of screw rod 1 end according to the needs that use according to conventional method value and making; Simultaneously the diameter of a circle φ of spherical end surface 2 and junction, screw rod 1 end is controlled at less than 0.3～0.5 millimeter of the thread root diameter of screw rod 1; And between the end thread of the circle of spherical end surface 2 and junction, screw rod 1 end and screw rod 1, make a scalene cone 3, and the angle between scalene cone 3 and screw rod 1 vertical line is made into 30 °～45 ° angle, can make screw rod 1 after machining, can well guarantee the uniformity of screw rod 1 size like this and alleviate the workload of subsequent handling; And reduce the distortion of screw rod 1 end and avoid screw rod 1 end to produce big burr, protect the integrality of the spherical end surface of screw rod 1 simultaneously.
During making, when the angle that the angle between scalene cone 3 and screw rod 1 vertical line is made into 30 °, adopt traditional rolling method to make; When the angle that the angle between scalene cone 3 and screw rod 1 vertical line is made into 45 °, adopting traditional car system method to make gets final product.
