Abstract
The utility model discloses a hole chamfer sword, its characterized in that: including installation fixing base and chamfer sword, the installation fixing base on seted up axially extending bore, axially extending bore forms by big internal diameter end and little internal diameter end, the cutter arbor and the rotation of little internal diameter end of chamfer sword are connected, the corresponding position of the same height held of internal diameter is highest greatly offers threaded hole, threaded hole is provided with the screw rod, the low -voltage line phase sequence signboard is advantageous in that, hole chamfer sword simple structure, collection chamfer sword and tubular product fixing device with together, and easily processing, assemble and the maintenance, secondly, be in the utility model discloses in, the chamfer sword rotates through the bearing with little internal diameter end to be connected, and the smooth rotation of chamfer sword in the time of not only can guaranteeing the chamfer has still reduced the loss to chamfer sword cutter arbor simultaneously, at last, the utility model discloses a stiff end of screw rod has still adopted and has cooperated inseparabler concave spherical surface with tubular product, has further increased stability, has just also further increased the precision of chamfer.
Description
Technical field
The utility model relates to five metals manufacture field, relates in particular to a kind of inner bore chamfering cutter.
Background technology
In field of machining, chamfering cutting is a kind of very important process technology, such as: at the interface chamfering of tubing, not only can remove the burr of tubing interface, can also increase the contact area of tubing interface, make the assembling of tubing become simpler; In prior art, be rose reamer for the instrument of chamfering cutting, but because existing rose reamer does not have the instrument of fixed cutting tool and tubing, so easily there is the phenomenon that rose reamer rocks at inner hole of pipe place in the time using the endoporus chamfering that rose reamer is tubing, thereby cause the chamfer machining failure at inner hole of pipe place.
Utility model content
The purpose of this utility model is to provide a kind of inner bore chamfering cutter, can avoid in the time using the endoporus chamfering that rose reamer is tubing, occurring the phenomenon that rose reamer rocks at inner hole of pipe place, ensures success rate and the accuracy of inner hole of pipe place chamfer machining.
In order to address the above problem, the utility model adopts following technical proposals:
A kind of inner bore chamfering cutter, comprise mounting-fixing base and rose reamer, on described mounting-fixing base, offer axially extending bore, described axially extending bore is made up of large diameter end and little inner-diameter end, the knife bar of rose reamer and little inner-diameter end are rotationally connected, the length value of little inner-diameter end is less than the length value of the knife bar of rose reamer, offers the screwed hole that is no less than two on the correspondence position of the sustained height of large diameter end, is provided with the screw rod matching with screwed hole in screwed hole.
On the inwall of described little inner-diameter end, be fixed with bearing, the knife bar of rose reamer and little inner-diameter end are dynamically connected by bearing rotary.
The stiff end of described screw rod is for being set to concave spherical surface.
On described concave spherical surface, be provided with anti-skidding projection.
Described screwed hole is provided with four.
The beneficial effects of the utility model are:
First, inner bore chamfering knife structure described in the utility model is simple, collection rose reamer and tubing fixture with together with, and be easy to processing, I& M; Secondly, in the utility model, rose reamer and little inner-diameter end are dynamically connected by bearing rotary, and the smooth rotation of rose reamer not only can ensure chamfering time has also reduced the loss to rose reamer knife bar simultaneously; Finally, on mounting-fixing base described in the utility model, offer screwed hole, in screwed hole, be provided with the screw rod for fixing tubing, can be by stable to rose reamer, mounting-fixing base and tubing being fixed as one, ensured the precision of chamfering, meanwhile, the stiff end of screw rod has also adopted and has coordinated concave spherical surface more closely with tubing, further increase stability, also just further increased the precision of chamfering.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, inner bore chamfering cutter described in the utility model, comprise mounting-fixing base 1 and rose reamer 2, on described mounting-fixing base 1, offer axially extending bore, described axially extending bore is made up of large diameter end and little inner-diameter end, little inner-diameter end is spacing for the knife bar 3 of rose reamer 2 is carried out, and large diameter end is for carrying out spacing to the tubing that need to carry out chamfer machining; Wherein, on the inwall of little inner-diameter end, be fixed with bearing 4, and the external diameter of bearing 4 and the internal diameter of little inner-diameter end match, knife bar 3 and the little inner-diameter end of rose reamer 2 are rotationally connected by bearing 4, like this, in the time utilizing rose reamer 2 to carry out chamfering to tubing, just can ensure the stability that rose reamer 2 rotates; Meanwhile, the length value of little inner-diameter end is less than the length value of the knife bar 3 of rose reamer 2, and it is tubing chamfering that the cutter head of guarantee rose reamer 2 can extend in large diameter end; On the sustained height correspondence position of the large diameter end of axially extending bore, also offer the screwed hole that is no less than two, in screwed hole, be provided with the screw rod 5 matching with screwed hole, in the time that tubing is carried out to chamfer machining, one end that tubing need to be processed extend in large diameter end, and tighten screw rod 5, make one end of screw rod 5 press tubing, now, screw rod 5, screwed hole, tubing and large diameter end cooperatively interact, can ensure relatively stable between rose reamer 2, mounting-fixing base 1 and tubing to prevent that chamfer machining is lack of standardization; In order to increase the stability between screw rod 5 and tubing, the stiff end of screw rod 5 is set to concave spherical surface 6 and described screwed hole is provided with four, the stiff end of concave spherical surface 6 shapes can coordinate more closely with tubing, on concave spherical surface, be also provided with anti-skidding projection, ensure that screw rod 5 can be fixed coffin more stable.
First, inner bore chamfering cutter 2 described in the utility model is simple in structure, collection rose reamer 2 and tubing fixture and one, and be easy to processing, I& M; Secondly, in the utility model, rose reamer 2 is rotationally connected by bearing 4 with little inner-diameter end, and the smooth rotation of rose reamer 2 not only can ensure chamfering time has also reduced the loss of the knife bar 3 to rose reamer 2 simultaneously; Finally, on mounting-fixing base 1 described in the utility model, offer screwed hole, in screwed hole, be provided with the screw rod 5 for fixing tubing, can be by rose reamer 2, mounting-fixing base 1 and stable being fixed as one of tubing, ensured the precision of chamfering, meanwhile, the stiff end of screw rod 5 has also adopted and has coordinated concave spherical surface 6 more closely with tubing, further increase stability, also just further increased the precision of chamfering.
