Abstract
The utility model discloses a flexible support of a boring cutter, which comprises a flexible supporting body which is arranged on the outer wall of a boring rod and at least positioned axially, can be supported between the boring rod and the inner wall of boring inner hole and is used for ensuring the coaxiality of the boring rod and the boring inner hole. The flexible support of the boring cutter has good adaptability to the surface of the inner hole, can adapt to tiny changes of the hole diameter of the inner hole, and is small in friction, good in quality of the inner hole surface, capable of avoiding clamping and free of potential safety hazards.
Description
Technical field
The utility model designs a kind of flexible support, relates in particular to a kind of boring cutter flexible support.
Background technology
When on lathe or boring machine, using boring bar and boring cutter to carry out deep hole machining, if boring bar is stretched oversizely, it is very poor that the rigidity of boring bar will become; Be prone to cause processing the circle that portals and beat greatlyyer, crudy will can not get guaranteeing, be that head it off increases the axiality of rigid support with assurance boring bar and institute's boring endoporus usually in the prior art on boring bar; But deep hole adds that the machined surface of confession is generally longer, and the wearing and tearing of cutter are very serious, and the size of endoporus is with inconsistent; Make rigid support and bore area produce frictional influence bore area quality, severe patient even rigid support are stuck in the workpiece endoporus, and percent defective is higher; The boring bar that fractures easily causes security incident.
Therefore,, need a kind of boring cutter flexible support, not only effectively guarantee the axiality of boring bar and institute's boring endoporus, also be beneficial to and improve the bore area quality, reduce potential safety hazard in order to address the above problem.
The utility model content
In view of this, the purpose of the utility model provides a kind of boring cutter flexible support, can guarantee the axiality of boring bar and institute's boring endoporus, and is good to bore area adaptability, and it is little to rub, and the surface quality that processes endoporus is better, can avoid stuck, no potential safety hazard.
The boring cutter flexible support of the utility model comprises being arranged at the boring bar outer wall also is used to guarantee boring bar and institute's boring endoporus axiality at least between the be supported in boring bar of axial location and the institute's boring endoporus inwall flexible support body.
Further; Said flexible support body is fixed in the boring bar setting; Comprise being placed in circumferentially equally distributed at least two flexible supporting block of the said body outer wall of fixing body of boring bar outer wall and edge, it is the processing diameter that is not less than corresponding boring cutter on the same circumference in center and to the distance of boring bar axis that the outer end under each flexible supporting block free state is positioned at the boring bar axis;
Further, the coefficient of elasticity of each flexible supporting block is identical;
Further; Said flexible supporting block is set to three; Each flexible supporting block is made up of pedestal, spring, supporting member and spacer pin; Said supporting member root inserts in the pedestal single-degree-of-freedom and is slidingly matched and carries out stroke limit through spacer pin, and said spring is arranged to be supported in the pedestal and is used to supporting member between base bottom and the supporting member elastic force along its glide direction is provided.
The beneficial effect of the utility model is: but the boring cutter flexible support flexible support of the utility model is in boring bar and institute's boring endoporus inwall; Guarantee the axiality of boring bar and institute's boring endoporus, good to bore area adaptability, the trace that can adapt to the endoporus aperture changes; It is little to rub; The bore area quality is good, can avoid stuck, no potential safety hazard.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Fig. 1 is the structural representation of the utility model; As shown in the figure: the boring cutter flexible support of present embodiment; Comprise and be arranged at boring bar 1 outer wall also is used to guarantee boring bar 1 and institute's boring endoporus 2 axialities at least between the be supported in boring bar 1 of axial location and institute's boring endoporus 2 inwalls flexible support body 3; The boring cutter flexible support of the utility model is good to bore area adaptability, can avoid stuck, no potential safety hazard.
In the present embodiment; Said flexible support body 3 is fixed in boring bar 1 and is provided with; Comprise being placed in the fixing body 31 of boring bar 1 outer wall and along circumferential equally distributed at least two flexible supporting block 32 of said body 31 outer walls, it is to be not less than the processing diameter of corresponding boring cutter on the same circumference in center and to the distance of boring bar 1 axis that the outer end under each flexible supporting block 32 free state is positioned at boring bar 1 axis, and the contact-making surface of flexible support body 3 and institute's boring endoporus 2 hole walls is less; It is little to rub, and is beneficial to guarantee the bore area quality.
In the present embodiment, the coefficient of elasticity of each flexible supporting block 3 is identical, is beneficial to the axiality that guarantees boring bar 1 and institute's boring endoporus 2, and serviceability is good.
In the present embodiment; Said flexible supporting block 32 is set to three, and each flexible supporting block 32 is made up of pedestal 321, spring 322, supporting member 323 and spacer pin 324, and said supporting member root inserts in the pedestal single-degree-of-freedom and is slidingly matched and carries out stroke limit through spacer pin; Said spring is arranged to be supported in the pedestal and is used to supporting member between base bottom and the supporting member elastic force along its glide direction is provided; The flexible supporting block of present embodiment is simple in structure, easy processing and fabricating, and cost is lower; Elasticity stable, serviceability is better.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
