Problems solved by technology

[0004] In the above technical solution, by using the cutter head under the drive of the screw nut, the control of the transmission accuracy can be realized, so as to ensure the precise cutting of the screw rod, but during the cutting process, because the cutting surface is easy to contact with the cutter head, resulting in After being cut, the cutting surface is worn by the contact of the rotating cutter head, which affects the machining accuracy of the screw. Therefore, there is an urgent need for a high-precision screw cutting device that can ensure that the cutting end surface will not be worn by the cutting head.

Embodiment 1

[0036] Such as figure 1 with 2 Shown, a screw high-precision cutting equipment, including:

[0037]The feed clamping part 1 and the discharge clamping part 2 are respectively arranged on both sides of the screw cutting point;

[0038] The breaking and pressing cutting assembly 3 arranged between the feeding clamping part 1 and the discharging clamping part 2;

[0039] The chamfering assembly 4 located on both sides of the cutting assembly 3; and

[0040] Drive the end face of the screw for cutting and separation to the guide assembly 5 in the chamfering area of ​​the chamfering assembly 4;

[0041] The feed clamping part 1 and the discharge clamping part 2 transport the fixed-length screw along the cutting vertical direction and then clamp the screw, and press the cutting assembly 3 to rotate around the cutting point and press the clamping screw in the discharge clamping part 2 , so that the cutting angle is opened to complete the cutting, and the guide assembly 5 sends th...

Embodiment 2

[0080] Such as figure 2 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between this embodiment two and embodiment one is:

[0081] The feed clamping part 1 includes:

[0082] Position the first positioning table 11 on one side of the cutting point of the interspersed screw;

[0083] a first bracket 12 elastically mounted on one side of the first positioning platform 11; and

[0084] The first pushing assembly 13 installed on the first bracket 12 and used for pinching the screw to the side of the first positioning platform 11 .

[0085] In this embodiment, when the feeding and clamping part 1 transports the screw toward the vertical direction of cutting, the screw passes through the first positioning table 11 to realize the positioning ...

Abstract

The invention provides high-precision cutting equipment for a screw rod in the technical field of machining. The high-precision cutting equipment comprises clamping parts arranged on the two sides of a cutting point of the screw rod correspondingly; a breaking-pressing cutting assembly arranged between the clamping parts; chamfering assemblies arranged on the two cutting sides of the breaking-pressing cutting assembly; and a guiding and conveying assembly used for driving the cut and separated end face of the screw to a chamfering area of the chamfering assembly. The clamping part conveys a fixed-length screw in the cutting vertical direction and then clamps the screw, the breaking and cutting assembly rotates and breaks the clamping screw in the clamping part with the cutting point as the center, so that the cutting included angle is opened to complete cutting, and the guiding and conveying assembly conveys the cut end face which is cut off to a chamfering area of the chamfering assembly for double-end chamfering. Thehigh-precision cutting equipment is particularly suitable for efficient machining of the double-end chamfering screw, such as a screw used on a machine tool, a spiral structure for pushing materials and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a high-precision screw cutting device. Background technique [0002] During the processing of the screw, the spiral groove is formed on the surface of the workpiece by using the milling cutter to helically cut the surface of the cylindrical blank, and after the spiral groove is formed, it is divided into fixed lengths according to the product process requirements, and in order to ensure that the screw For the stability of the surface spiral groove body after forming, a rotating cutting tool is often used to cut the screw instead of direct cutting, so as to avoid the extrusion of the spiral groove body when the spiral groove body is directly cut off. [0003] In order to realize automatic processing in the process of screw rod fixed-length cutting, Chinese patent CN107090526A discloses a screw drive cutting machine, including a frame, which includes a bottom frame an...
