Abstract

The utility model discloses a PCD screw type reamer, which comprises a reamer body and a reamer shank, wherein a positioning structure is arranged at the top of the reamer body, and includes two positioning bulges, and the two positioning bulges are cones arranged at the two ends of the top surface of the reamer body; a clamping component is arranged at the outer part of the tail end of the reamer shank; the clamping component adopting a structure of a frustum of a cone is integrated with the reamer shank; the ratio of the front end height H1 of the clamping component to the tail end height H2 of the clamping component is 1.5 : 1; symmetrically arranged arc-shaped grooves are formed in the two sides of the clamping component; the central axial plane of the reamer shank is used as a base level; the front end vertex angle Alpha of the clamping component is 48 degrees. The PCD screw type reamer has the benefits that through the special positioning structure arranged at the top of the reamer body, accurate positioning of the reamer body during cutting is realized, and deviations are less susceptible to occur; the clamping component arranged on the reamer shank effectively clamps the cutting tool, so that the loss of enterprises is reduced, the manufacturing cost of enterprises is decreased, and the production efficiency of enterprises is greatly improved.

Description

The spiral reamer of a kind of PCD

Technical field

The utility model relates to the spiral reamer of a kind of PCD, belongs to Metal Cutting technical field of tools.

Background technology

Machining industry cutter is to high accuracy, high-speed, high efficiency future development at present, polycrystalline diamond (being called for short PCD) aperture knife tool is a kind of as the higher cutter of current utilization rate, its work in-process Tool in Cutting exists and is difficult for location, easily there is the phenomenon of deviation, enterprises production efficiency is impacted.And because drilling tool needs High Rotation Speed in boring procedure, need to realize tight clamping with fixture, current reamer shank end on the market is mostly cylinder, when boring High Rotation Speed, tend to skid, fixture is not easy to clamp, and even has the possibility dropping from fixture, produces potential safety hazard.Therefore, develop a kind of being easy to and locate, and the spiral reamer of the PCD being easily fixedly clamped more and more receives people's concern.

Utility model content

Technical problem to be solved in the utility model is to provide the spiral reamer of a kind of PCD for above drawback, by the special location structure arranging at cutter hub top, realize the accurate location of cutter hub when cutting, be difficult for occurring deviation, at handle of a knife position, clamping component is set, cutter is effectively clamped, reduce enterprises' loss, reduce enterprise's production cost, greatly improve enterprises production efficiency.

For solving the problems of the technologies described above, the technical solution of the utility model is:

The spiral reamer of PCD, comprises cutter hub and handle of a knife, and wherein, described cutter hub top is provided with location structure, and described location structure comprises two positioning convex, and described positioning convex is cone, is distributed in cutter hub end face two ends; Described handle of a knife end outside is provided with clamping component, and described handle of a knife and described clamping component are integral structure, and described clamping component is Rotary-table structure, and described clamping component front end height H 1 with the ratio of clamping component end height H 2 is: 1.5:1; Described clamping component both sides are provided with arc groove, and described arc groove is symmetrical set; Take handle of a knife central axis plane as datum level, and described clamping component front end apex angle α is 48 degree.

The beneficial effects of the utility model are:

1, by the special location structure arranging at cutter hub top, realize the accurate location of cutter hub when cutting, two positioning convex are located simultaneously, are difficult for deviation occurs, and can effectively enhance productivity.

2, at handle of a knife position, clamping component is set, unique circular platform type structure increasing and the contact area between fixture, strengthen coefficient of friction; And make low structural design after the distinctive front height of round platform, cutter is more easily advanced in boring procedure; Through inferior experiment tests up to ten thousand, show, when clamping component front end apex angle α is 48 degree, and clamping component front end height H 1 with the ratio of clamping component end height H 2 is: during 1.5:1, boring is that active force is minimum, is easy to boring most and advances.

3, the arc groove that clamping part both sides correspondence is provided with, agrees with arc tongue corresponding on fixture, can make effectively to clamp between cutter and fixture, reduces enterprises' loss, reduces enterprise's production cost, greatly improves enterprises production efficiency.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in the figure, the spiral reamer of a kind of PCD of the utility model, comprises cutter hub 1 and handle of a knife 2, wherein, described cutter hub 1 top is provided with location structure 3, and described location structure 3 comprises two positioning convex 4, described positioning convex 4 is cone, is distributed in cutter hub 1 end face two ends; Described handle of a knife 2 end outsides are provided with clamping component 5, and described handle of a knife 2 is integral structure with described clamping component 5, and described clamping component 5 is Rotary-table structure, and described clamping component 5 front end height H 1 with the ratio of clamping component end height H 2 are: 1.5:1; Described clamping component 5 both sides are provided with arc groove 6, and described arc groove 6 is symmetrical set; Take handle of a knife central axis plane as datum level, and described clamping component 5 front end apex angle α are 48 degree.

The beneficial effects of the utility model are: by the special location structure arranging at cutter hub top, realize the accurate location of cutter hub when cutting, two positioning convex are located simultaneously, are difficult for deviation occurs, and can effectively enhance productivity.At handle of a knife position, clamping component is set, unique circular platform type structure increasing and the contact area between fixture, strengthen coefficient of friction; And make low structural design after the distinctive front height of round platform, cutter is more easily advanced in boring procedure; Through inferior experiment tests up to ten thousand, show, when clamping component front end apex angle α is 48 degree, and clamping component front end height H 1 with the ratio of clamping component end height H 2 is: during 1.5:1, boring is that active force is minimum, is easy to boring most and advances.The arc groove that clamping part both sides correspondence is provided with, agrees with arc tongue corresponding on fixture, can make effectively to clamp between cutter and fixture, reduces enterprises' loss, reduces enterprise's production cost, greatly improves enterprises production efficiency.

Above embodiment is only for being further described the utility model; can not be interpreted as the restriction to the utility model protection domain, some nonessential improvement that those skilled in the art makes according to foregoing of the present utility model and adjustment all belong to protection domain of the present utility model.
