Abstract
The utility model discloses a kind of mill hard alloy die cavity feed well frotton structural assembly, relate to Grinding Technology field, including collet, frotton, having clamping hole, the top of described frotton inside described collet is bare terminal end, and described bare terminal end coordinates with the clamping hole of collet, the top surface of described bare terminal end offers screwed hole, axially arranged along frotton of described screwed hole, described screwed hole and a corresponding screw fit, the head diameter of described screw is more than the external diameter of bare terminal end.Mill hard alloy die cavity feed well frotton structural assembly of the present utility model offers screwed hole on the bare terminal end top of frotton, non-standard screw is used to prevent frotton after long-term high-speed rotation, axially downwardly slide, affect the processing of die cavity, produce waste product, have simple and reliable for structure, it is easy to the advantages such as dismounting and change.
Description
Technical field
This utility model relates to Grinding Technology field, is specifically related to a kind of mill hard alloy die cavity feed well frotton knot
Structure assembly.
Background technology
Hard alloy die cavity grinding process loosens because of shake due to main shaft high speed rotating, collet, it is impossible to folder
Tight frotton, frotton moves down.The feed well closed height size causing grinding to go out does not reaches figure.
In grinding process, as found the most in time, frotton moves downward operator, and frotton moves down size as relatively
Greatly, die cavity feed well closed height size will be little several centimetres, causes work loading height size inadequate, hard alloy die cavity report
Useless.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of mill hard alloy die cavity feed well frotton structure total
Become, solve frotton vertical play excessive, affect die cavity machining accuracy problem.
The technical scheme used for realizing the purpose of this utility model is: a kind of mill hard alloy die cavity feed well frotton knot
Structure assembly, it is characterised in that include collet, frotton, has the clamping hole, the top of described frotton to be inside described collet
Bare terminal end, described bare terminal end coordinates with the clamping hole of collet, and the top surface of described bare terminal end offers screwed hole, described
Axially arranged along frotton of screwed hole, described screwed hole and a corresponding screw fit, the head diameter of described screw is more than
The external diameter of bare terminal end.
Further, described bare terminal end exceeds collet upper surface 0.2mm ~ 0.3mm.
Further, the nut thickness of described screw is less than 5mm.
Further, the bottom of described frotton is grinding end, and described grinding end surfaces is provided with silicon carbide layer, described corundum
Thickness is 0.2mm.
Further, the nut of described screw is nonstandard bar shaped nut, and narrow limit is circular arc.
Further, described screw uses No. 45 steel, and hardness is between HRC43 ~ 48.
The beneficial effects of the utility model:
A kind of mill hard alloy die cavity feed well frotton structural assembly that this utility model provides, for preventing frotton from moving down,
Frotton upper end now adds M6 silk hole, and frotton upper end is screwed on collet in use, and allows frotton clamp small end
Length is more than collet height overall 0.2～0.3 mm, prevents screw from being killed by collet after tightening.
Owing to inner hole of spindle is blind hole, only 5 mm rooms after collet is loaded, therefore head thickness size is thinner than 5
Mm, to prevent collet not in place with spindle mounted.
The nut of screw is nonstandard bar shaped nut, and narrow limit is circular arc, compared with hex nut, has repeatedly to dismantle and still can
Ensureing that the shape of nut is not disassembled instrument and polishes, it uses No. 45 steel, and Hardness Control is a scope, ensures its integrated machine
Tool performance, will not too soft two surrenders, also will not be too hard and rupture.
When frotton upper end is prevented from main shaft high speed rotating after adding screwing, frotton moves downward.
Accompanying drawing explanation
Fig. 1 is the structural representation of the mill hard alloy die cavity feed well frotton structural assembly that this utility model provides；
Fig. 2 is the top view of the mill hard alloy die cavity feed well frotton structural assembly that this utility model provides.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing this utility model is described in further detail.
Fig. 1 shows a kind of mill hard alloy die cavity feed well frotton structural assembly that this utility model provides, including bullet
Spring chuck 1, frotton 2, collet 1 is internal clamping hole 7, and the top of frotton 2 is bare terminal end 6, bare terminal end 6 and collet 1
Clamping hole 7 coordinate, the top surface of bare terminal end 6 offers screwed hole 3, and screwed hole 3 is axially arranged along frotton 2, screwed hole 3
Screw 4 corresponding with one coordinates, and the head diameter of screw 4 is more than the external diameter of bare terminal end 6.In the present embodiment, bare terminal end 6 is high
Go out 1 upper surface 0.2mm ~ 0.3mm of alligator clamp, prevent screw 4 from being killed by collet 1 after tightening；Due to machine tool chief axis endoporus
For blind hole, only have 5 mm rooms after being loaded by collet 1, therefore the nut gauge of screw 4 is thinner than 5 mm, to prevent spring
Chuck 1 is not in place with spindle mounted.
The bottom of frotton 2 is grinding end, and grinding end surfaces is provided with silicon carbide layer 5, and corundum thickness 5 is 0.2mm.
As described in Figure 2, the nut of screw 4 is nonstandard bar shaped nut, and narrow limit is circular arc, compared with hex nut, has repeatedly
Dismounting still can ensure that the shape of nut is not disassembled instrument and polishes, and it uses No. 45 steel, and Hardness Control exists in hardness
Between HRC43 ~ 48, ensure its comprehensive mechanical performance, will not too soft two surrenders, also will not be too hard and rupture.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this area
Technical staff for, this utility model can have various modifications and variations.It is all within spirit of the present utility model and principle,
Any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
