Abstract

The invention relates to the field of automobile part machining equipment, in particular to a curved chamfering mechanism for a throttle shaft. The curved chamfering mechanism comprises a base, and further comprises a tooling fixture and a tool rest which are movably arranged on the base; the tooling fixture reciprocates in the axial direction of the throttle shaft, and is used for fixing the throttle shaft and positioning the circumferential direction of the throttle shaft; the tool rest reciprocates in the radial direction of the throttle shaft; and a tool bit is arranged on the tool rest, can extend into a long flat groove of the throttle shaft, and performs chamfering treatment on the long flat groove of the throttle shaft in the movement process of the tooling fixture. The curved chamfering mechanism for the throttle shaft adopts semi-automatic numerical control, and all other actions are automatically completed by program control except that loading and unloading are performed manually. The curved chamfering mechanism has the advantages that the production efficiency is high, the chamfering consistency is good, product model changing is quick, the curved chamfering mechanismis suitable for deburring of chamfers of valve shafts of various sizes, the operation is simple, the performance is stable.

Description

technical field [0001] The invention relates to the field of auto parts processing equipment, in particular to a curve chamfering mechanism for a throttle shaft. Background technique [0002] The throttle shaft is a part used in the control mechanism of the automobile engine. It is made of 304 stainless steel and 420F free-cutting steel. It has good toughness and high strength. It is used as a valve shaft to control the intake air volume of the valve. The machining accuracy of the throttle shaft surface is required to be high, especially the machining of the long groove on the electronic throttle shaft. The existing throttle shaft diameters are 8mm and 10mm, and the length is 84.3mm to 137.2mm. There are more than 30 specifications. There are 60° center holes at both ends, and there are screw holes, thread teeth, annular grooves, etc. on the shaft. There is a long flat groove in the middle, which is opened symmetrically from both sides of the central axis. The width of the ...
