Problems solved by technology

The above technical solutions have the following defects: after the heat treatment of the nut, it is necessary to grind the internal thread raceway, and the grinding must be corrected one by one before grinding, so the processing efficiency is low and the production cycle is long

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Depend on image 3 As shown, the forming turning tool includes a handle 1 and a cutter head 2, and the cutting edge 3 of the cutter head 2 includes two arcs, and the two arcs are connected at a common end 4, and the cutting edge of the forming turning tool 3 shapes with figure 2 The nut raceway tooth profile shown in .

[0017] Depend on figure 1 As can be seen from the flow chart of the ball screw pair nut raceway processing process of the present invention, it includes the following steps: using the cutting edge 3 to machine the nut made of free-cutting steel to turn out the nut raceway, and obtain the intermediate piece after the turning process is completed Nuts, intermediate nuts are heat-treated and changed to obtain finished nuts, so that the tooth shape of the raceway of the finished nuts meets the requirements of u...

Abstract

The invention discloses a turning tool and a ball screw assembly nut roller path machining method based on the turning tool. The turning tool comprises a tool handle (1) and a tool bit (2), and a cutting edge (3) of the tool bit (2) comprises two arcs connected at a common end (4). The method includes the steps: turning a nut made of free cutting steel to form a nut roller path by using the cutting edge (3) and obtaining an intermediate nut; and then performing heat treatment for the intermediate nut to obtain a finished nut. Grinding is omitted, machining efficiency is improved, machining time is shortened, and the use requirements of the nut roller path on precision, normal section shape and roughness can be effectively met.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a turning tool and a ball screw nut raceway processing method using the turning tool. Background technique [0002] The ball screw pair is a component composed of a ball screw, a ball nut and a ball. It is the transmission device with the highest precision and the most commonly used in transmission machinery at present. Generally, the material used for processing the nuts of ball screw pairs is high carbon steel (such as: bearing steel GCr15, 50# steel, etc.), which is relatively hard and difficult to process, and cannot guarantee smoothness, roundness, taper, raceway shape and In addition, the shape of the normal section of the nut after heat treatment (commonly known as the tooth profile of the nut raceway) will change to a certain extent, so it is necessary to grind the raceway on an internal thread grinder to meet the requirements of use, so the general ball nut raceway pro...
