Abstract
The utility model discloses a kind of specific purpose tool of lathe roll extrusion aperture, it comprises Morse taper shank (1), be arranged on the cages for needle (2) of Morse taper shank (1) one end, be arranged on the needle roller (3) of cages for needle (2) right-hand member, described needle roller (3) is by pressure cap (4), and pad (5) and hold-down bolt (6) are fixed on Morse taper shank (1).The specific purpose tool of the lathe roll extrusion aperture that the utility model provides, reasonable in design, easy to operate, operating efficiency is high, and the form and position tolerance of the workpiece obtained after processing is little, not easily forms the defects such as horn mouth, process the aperture workpiece quality obtained high, precision is high, practical.
Description
Technical field
The utility model relates to a kind of mechanical device, is specifically related to a kind of specific purpose tool of lathe roll extrusion aperture.
Background technology
In prior art, often need the foraminate workpiece of processing tool, prior art carries out turning, then carries out grinding, as adopted grinding tapering diamond lap, the form and position tolerance of the workpiece obtained after processing is larger, and underhand polish, easily forms the defects such as horn mouth, processes the workpiece quality obtained lower, precision is low, can not meet the standard of high request.
Therefore, on the basis of existing technology necessary, research and develop a kind of reasonable in design, easy to use, operating efficiency is high, and the form and position tolerance of the workpiece obtained after processing is little, not easily forms the defects such as horn mouth, process the workpiece quality obtained high, the specific purpose tool of the lathe roll extrusion aperture that precision is high.
Utility model content
Utility model object: the purpose of this utility model is to solve the deficiencies in the prior art, a kind of reasonable in design is provided, easy to use, operating efficiency is high, the form and position tolerance of the workpiece obtained after processing is little, not easily form the defects such as horn mouth, process the workpiece quality obtained high, the specific purpose tool of the lathe roll extrusion aperture that precision is high.
Technical scheme: in order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A specific purpose tool for lathe roll extrusion aperture, it comprises Morse taper shank, is arranged on the cages for needle of Morse taper shank one end, is arranged on the needle roller of cages for needle right-hand member, and described needle roller is by pressure cap, and pad and hold-down bolt are fixed on Morse taper shank.
Preferably, the specific purpose tool of above-described lathe roll extrusion aperture, described needle roller is 3 ~ 6.
As being more preferably scheme, the specific purpose tool of above-described lathe roll extrusion aperture, described needle roller is 3.
Preferably, the specific purpose tool of above-described lathe roll extrusion aperture, described Morse taper shank left end is arranged in tail stock taper hole.
Preferably, the specific purpose tool of above-described lathe roll extrusion aperture, the diameter D≤5mm of described needle roller, the length of needle roller and diameter ratio are greater than 2.5.
The specific purpose tool of the lathe roll extrusion aperture that the utility model provides, concrete implementation step: first loaded by Morse taper shank in tail stock taper hole during roll extrusion, shake handwheel, by needle roller roll extrusion workpiece, workpiece leaves the hole of 0.01 ~ 0.02mm surplus.The specific purpose tool of the lathe roll extrusion aperture that the utility model provides, thick fine finishining clamped one time can complete, and carries out grinding again than after prior art turning, and operating efficiency can improve more than 10 times, and after processing, precision is higher.
The specific purpose tool of the lathe roll extrusion aperture that the utility model provides, Morse taper shank material is preferably 9CrSi, heat treatment hardness HRC60 ~ 64, be out of shape little, wearability is high.Described cages for needle material selection brass.The utility model loads in tail stock hole due to Morse taper shank, can ensure the Geometrical Tolerance Principle of workpiece to be machined, avoid underhand polish easily to form the defects such as horn mouth.
Beneficial effect: compared to the prior art the specific purpose tool of the lathe roll extrusion aperture that the utility model provides has the following advantages:
The specific purpose tool of the lathe roll extrusion aperture that the utility model provides, reasonable in design, easy to operate, operating efficiency is high, and the form and position tolerance of the workpiece obtained after processing is little, not easily forms the defects such as horn mouth, process the aperture workpiece quality obtained high, precision is high, practical.
