Abstract
The invention relates to the field of machinery machine tools, in particular to a novel spring center. The novel spring center comprises a center body, a clamping-holding part, a locating pin and a taper shank, wherein the clamping-holding part is located at one end of the taper shank, the center body is arranged in a locating hole of the clamping-holding part, a spring is arranged between the end of the center body and the locating hole, the upper surface of the clamping-holding part is provided with a limiting groove communicated with the locating hole, the center body is provided with a pin hole, and the locating pin penetrates through the limiting groove and is inserted into the pin hole. As the spring is arranged between the end of the center body and the locating hole, axial force exerted on the center can be relieved, the center is prevented from bursting apart, and the service life of the novel spring center is prolonged.
Description
Technical field
The present invention relates to mechanical machine tool field, particularly a kind of novel elastic is top.
Background technology
Top, the machine tool component in machining, has two kinds of stationary center and rolling centers.Stationary center can and not allow the part of centering to support to the part of end face complexity.Top one end can top centre bore or the endoporus of materials in the tube, and the other end can top end face be spherical or the part of taper.Top boring, cover tooth and the fraising that also can be used for workpiece.On Digit Control Machine Tool with existing top while establishing coordinate or groove on workpiece, top easy chipping, and cause top scrapping.
Summary of the invention
The object of this invention is to provide a kind of novel elastic top, can slow down top axial force.
Technical scheme of the present invention is as follows: novel elastic is top, comprise top, clamping part, alignment pin and taper shank, described retaining part is in one end of described taper shank, in the described top locating hole of being located at described clamping part, between described top end and locating hole, be provided with spring, described clamping part upper surface is provided with the stopper slot being communicated with described locating hole, the described top pin-and-hole that is provided with, and described alignment pin inserts in described pin-and-hole through described stopper slot.
Described stopper slot is L shaped.Described stopper slot is zigzag.
Described top be carbide-tipped center.
Described taper shank is No. 4 taper shanks of Mohs.
Between top end and locating hole, be provided with spring, can alleviate top suffered axial force, thereby avoided the situation of top chipping, postponed its service life.Top is carbide-tipped center, than common top hardness, has increased.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, novel elastic of the present invention is top, comprises top 1, clamping part 5, alignment pin 2 and taper shank 4, and described clamping part 5 is positioned at one end of described taper shank 4, described top 1 is located in the locating hole 6 of described clamping part 5, between described top 1 end and locating hole 6, is provided with spring 3.Described clamping part 5 upper surfaces are provided with the stopper slot 6 being communicated with locating hole 6, and described stopper slot 6 is L shaped, and stopper slot 6 can also be zigzag.Described top 1 is provided with pin-and-hole 8, and described alignment pin 2 inserts in pin-and-hole 8 through stopper slot 6, plays stationary center 1.When workpiece machines, the short portion of running fix pin 2 from the long portion of L shaped stopper slot 6 to stopper slot 6, alignment pin 6 can be extracted from pin-and-hole 7, and top 1 is subject to the elastic force of spring 3 to release clamping part 5, and top 1 can take out very easily.
