Numerical control lathe tube processing feeding structure

Abstract

The invention discloses a guide tube machining feeding structure of a numerical-control lathe. The guide tube machining feeding structure comprises a base, a feeding tube, a support plate, a feeding support, a feeding cylinder, a feeding groove, a pretensioning spring, a feeding rod and a pre-pressing spring. The feeding tube corresponds to a conveying hole which is formed in the base, the support plate is fixed onto the base, the feeding cylinder is arranged on the support plate, a piston rod of the feeding cylinder vertically penetrates the support plate and is fixed to the feeding support, a leg I is arranged in the middle of the bottom of the feeding support, and a leg II is arranged at an end of the feeding support; one end of the feeding groove is hinged to the leg I, and the other end of the feeding groove corresponds to the conveying hole; the feeding rod horizontally penetrates the leg I and the leg II, and the pre-pressing spring is arranged between the other end of the feeding rod and the leg II. The guide tube machining feeding structure has the advantages that guide tubes to be machined can be fed into the feeding groove via a conveying tube and the conveying hole, the feeding cylinder can drive the feeding support to downwardly move, an ejector pin on a tailstock can drive the feeding rod, accordingly, the guide tubes to be machined can be clamped on a chuck, the feeding cylinder can drive the feeding support to withdraw after the tailstock withdraws, automatic loading effects can be realized, and the work efficiency can be greatly improved.

Description

technical field [0001] The invention relates to machining equipment, in particular to a numerically controlled lathe conduit machining and feeding structure. Background technique [0002] 125 ducts are widely used as the intake and exhaust pipes of motorcycle engines, and its manufacturing process mainly includes three parts: 1. Press the metal powder with a powder product hydraulic press to form a model of 125 ducts; 2. Heat and fire the model of 125 ducts , to fuse the pressed metallurgical powder; 3. Carry out metal cutting processing. [0003] In the prior art, the intake duct is processed by numerical control equipment such as the C616 lathe and the CH300 micro lathe, which requires a total of 9 processing procedures to complete. When processing the head of the duct, it only relies on manual loading, and the operator will The blank is clamped on the chuck of the lathe, and the tailstock is moved to make the thimble on the tailstock stand against the blank to be process...

[0003] In the prior art, the intake duct is processed by numerical control equipment such as the C616 lathe and the CH300 micro lathe, which requires a total of 9 processing procedures to complete. When processing the head of the duct, it only relies on manual loading, and the operator will The blank is clamped on the chuck of the lathe, and the tailstock is moved so that the thimble on the tailstock is against the blank to be processed. This method of manual operation is extremely low in production efficiency.
