Abstract
The invention relates to an elastic floating support for bearing ring machining, which comprises a rear support base and support heads, and is characterized in that the elastic floating support is also provided with an elastic floating block, an elastic floating block pin and support head pins; the elastic floating block is connected with the rear support base through the elastic floating block pin for angle adjustment, and the support heads are connected with the elastic floating block through the support head pins for angle adjustment. Hard alloy blocks are fixed on the support heads. Two support heads are mounted on the elastic floating block. A gap for increasing elasticity is machined on the upper surface of the elastic floating block. The invention has the following advantages that: the elastic floating support can prevent burns and deformation in the machining process through the elastic effect, improves the contact area of the elastic floating support and the product precision.
Description
Technical field:
The present invention relates to a kind of elastic floating support of bearing ring processing usefulness, be mainly used in the mill processing of bearing ring cylindrical.
Background technology:
Bearing (bearing) is a kind of being applied on the rotating mechanism, is used for supporting the parts of reducing friction and bearing load.The quality of grinding bearing rings quality directly has influence on the quality quality of finished product bearing.
Elastic floating support is a kind of being applied in processing of bearing ring peripheral milling or the processing of septal fossula mill; Be used for supporting and bear lasso at mill process grinding force; The floating support that adopts is at present connect through pin 2 ' by rear branching holder 1 ' and supporting head 3 '; Referring to Fig. 1, this product is simple in structure because of it, the following shortcoming of existence:
1. though adopt this directly simple in structure through the assembly that pin 2 ' connects at present by rear branching holder 1 ' and supporting head 3 '; But when exist grinding force excessive with lasso circularity when relatively poor; As easy as rolling off a log generation lasso scorch and distortion, thus bearing initial failure caused.
2. this structure can only use a supporting head 3 ' and lasso contact-making surface less, causes the lasso machining accuracy not high, thereby causes the bearing completed products running accuracy not high.
Present structure can not solve the problem of burn and precision raising well.
Summary of the invention:
Technical problem to be solved by this invention is to overcome existing above-mentioned deficiency in the prior art, and a kind of elastic floating support of bearing ring processing usefulness is provided.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of elastic floating support of bearing ring processing usefulness; Comprise rear branching holder, supporting head; It is characterized in that also being provided with elastic floating piece, elastic floating piece pin and supporting head pin; Elastic floating piece and rear branching holder connect and the adjustment angle through elastic floating piece pin, and supporting head connects and the adjustment angle through supporting head pin and elastic floating piece.
Be fixed with hard alloy blocks on the supporting head of the present invention.
2 supporting heads are installed on the elastic floating piece of the present invention.
Have above the elastic floating piece of the present invention and be used for increasing flexible breach.
Breach according to the invention is two.
Breach according to the invention be rectangle combination or circular arc with circular arc.
Rear branching holder of the present invention, supporting head adopt brass, and the elastic floating piece adopts spring steel 65Mn.
The present invention has the following advantages and effect: can reduce the burn problem in the processing of lasso mill, have the precision and the working (machining) efficiency that improve the processing of lasso mill again.

The specific embodiment:
Referring to Fig. 2～Fig. 8, the elastic floating support of embodiment of the invention bearing ring processing usefulness is made up of a rear branching holder 1, elastic floating piece pin 2, elastic floating piece 3, two supporting heads 4 and two supporting head pins 5.Rear branching holder 1 can be fixed on the chuck of grinding machine; Rear branching holder 1 connects through elastic floating piece pin 2 with elastic floating piece 3, and elastic floating piece 3 can elastic floating piece pin 2 be the center, relatively the certain anglec of rotation of rear branching holder 1 adjustment; Supporting head 4 is put into the supporting head hole 32 on the elastic floating piece 3 from above; Connect through supporting head pin 5 and elastic floating piece 3 then, supporting head 4 can supporting head pin 5 be the center, the certain anglec of rotation of relative resilient rocker piece 3 adjustment; Supporting head 4 is provided with hard alloy blocks 6, connects through brazing.Two supporting heads 4 (having increased the enveloping surface with the processing lasso) are installed on the elastic floating piece 3; Have two symmetrically arranged breach 31 on the elastic floating piece 3; The combination (seeing shown in Figure 4) with circular arc of being rectangle of a kind of shape of breach 31; The another kind of shape of breach 31 is circular arc (seeing shown in Figure 6), and when grinding force was excessive, the breach 31 in the elastic floating piece 3 can increase elasticity (position of elastic floating piece 3 mounting support heads 4 has the ability of elastic buffer with respect to elastic floating piece 3 elasticity breach or circular arc); Play certain cushioning effect, can prevent lasso distortion and burn.
The design feature of the embodiment of the invention makes bearing life, precision and working (machining) efficiency improve, because: 1. adopt elastic floating piece 3 can prevent that lasso from adding the distortion and the burn in man-hour; 2. adopt the containing area that two supporting heads 4 have increased lasso is installed on the elastic floating piece 3, improved the precision and the working (machining) efficiency of product.
