Abstract
The utility model discloses a structure for preventing overturned burr of a screw rod component with a spherical end surface, which comprises a screw rod with a spherical end surface. Diameter of a circle at a bonding position of the spherical end surface at the end of the screw rod and the end of the screw rod is smaller 0.3 to 0.5 millimeters than that of the root of the screw thread of the screw rod and further an inclined cone-shaped surface is arranged between the circle at the bonding position of the spherical end surface at the end of the screw rod and the end of the screw rod. The utility model changes the spherical end surface structure of the existing screw rod component so that after thread machining, the end surface deformation of the component can be reduced and the larger burr is avoided, and meanwhile integrality of the spherical end surface is ensured, further consistency of size of the component can be ensured and workload of the subsequent work sequences can be lightened so as to reduce the machining difficulty. The utility model not only has the advantages of reducing the end surface deformation of the screw rod and preventing the larger burr at the end, but also has the advantages of easy machining, high quality of the machined screw rod with the spherical end surface and the like.
Description
Technical field
The utility model relates to a kind of structure that prevents to have the screw rod part frizzled feather thorn of spherical end surface, belongs to the connecting screw rod technical field.
Background technique
Since mechanical industry is come out, the Placement between various mechanical structures the most effective easy be exactly to be threaded, be extensive use of invariably as 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, reason owing to existing screw-rod structure, screw rod end face after rolling or the processing of car system all can produce burr, make its end face produce distortion, thereby influence the processing of accessory size and subsequent handling.Therefore, existing screw-rod structure is still reasonable inadequately.
The model utility content
The purpose of this utility model is: provide a kind of and can reduce the screw rod face deformation and avoid the end to produce the structure of screw rod part frizzled feather thorn that prevents to have spherical end surface of big burr, thereby overcome the deficiencies in the prior art.
The utility model is to constitute like this: a kind of structure that prevents to have the screw rod part frizzled feather thorn of spherical end surface of the present utility model comprises the screw rod that has the ball-type end face, the diameter of a circle of the spherical end surface of its screw rod end and junction, screw rod end is less than 0.3～0.5 millimeter of screw flight root diameter (RD), and is provided with tilted conical surface between the end thread of the circle of spherical end surface and junction, screw rod end and screw rod.
The angle of the angle between above-mentioned tilted conical surface and the screw rod vertical line is 30 °～45 °.
Owing to adopted technique scheme, the utility model is by changing the spherical end surface structure of existing screw rod part, thereby make this part after screw thread processing, can reduce the end distortion and avoid producing big burr, guaranteed the integrity of spherical end surface simultaneously, and more can guarantee the conformity of accessory size and alleviate the workload of subsequent handling, greatly reduce difficulty of processing.Therefore, the utility model compared with prior art, the utility model not only has and can reduce the screw rod face deformation and prevent that the end from producing the advantage of big burr, but also the spherical end surface screw rod quality advantages of higher that has easy processing and process.
Description of drawings
Fig. 1 is the structural representation of the utility model screw rod.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: 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 determined 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 tilted conical surface 3; angle α between tilted conical surface 3 and screw rod 1 vertical line is made into 30 °～45 ° angle; can make screw rod 1 after machining, can well guarantee the conformity and the workload that alleviates subsequent handling of screw rod 1 size like this; and reduce the distortion of screw rod 1 end and avoid screw rod 1 end to produce big burr, protect the integrity of the spherical end surface of screw rod 1 simultaneously.
During making, when the angle that the angle α between tilted conical surface 3 and screw rod 1 vertical line is made into 30 °, adopt traditional rolling method to make; Adopting traditional car system method to make when the angle α between tilted conical surface 3 and screw rod 1 vertical line is made angle at 45 gets final product.
