Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as Figure 1 to Figure 4 , an improved center, including a live center 3, a clamp body 1 and a cage 6, the clamp body 1 is provided with a guide groove 2, the live center 3 is arranged in the guide groove 2, the bottom of the guide groove 2 and or the top A spring 4 is provided between the tails of the clamp body 1, and a floating disc 5 set on the live center 3 is also provided on the chuck body 1. The floating disc 5 is connected with the clamp body 1 through a cage 6, and the top of the head of the live center 3 There are small holes 9 and spiral grooves 10 communicating with each other on the head, and a guide hole 8 communicating with the small holes 9 is also provided inside the live center 3 .

[0016] Two edges 7 are respectively arranged on the two ends of the floating plate 5, and the two edges 7 are arranged perpendicula...

Abstract

The invention relates to an improved tip which comprises a movable tip, a clamp body and a retainer. A guide groove is formed in the clamp body, the movable tip is arranged in the guide groove, a spring is arranged between the bottom of the guide groove and the tail portion of a tip rod, a floating disc arranged on the movable tip in a sleeving mode is further arranged on the clamp body and connected with the clamp body through the retainer, a small hole and a spiral groove which are mutually communicated are formed in the tip head at the head portion of the movable tip, and a guide hole communicated with the small hole is further formed in the movable tip. The improved tip has the advantages of being simple in structure, long in service life, capable of reducing abrasion and meanwhile ensuring radial run-out of parts, end face run-out and turning allowance of the end faces, and the like.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an improved tip. Background technique [0002] When the machine tool is processing the workpiece, in order to ensure the accuracy and coaxiality of the workpiece, a center will be installed at the end of the machine tool to withstand the workpiece. During the machining process, the high-speed rotation of the workpiece will cause wear at the contact between the tail end of the workpiece and the tip, reducing the service life of the tip, and in severe cases, the axial runout of the workpiece will occur during processing, reducing the accuracy of the workpiece. The radial runout, end surface runout and end surface turning allowance of the shaft and disk parts cannot be guaranteed at the same time by the traditional positioning method. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide an improved center with simp...
