Abstract
The invention discloses a jig for machining an inner hole of a thin-walled female die. The jig comprises a jig body, wherein a hole is formed in one axial end of the jig body, a positioning hole communicated with the hole is formed in the other axial end of the jig body, the diameter of the hole is smaller than the outer diameter of the thin-walled female die, the positioning hole and the jig body are axially concentric, the positioning hole and the thin-walled female die are in close sliding fit, a pressing plate is detachably connected on the jig body, a limiting hole is formed in the pressing plate, and the diameter of the limiting hole is smaller than the outer diameter of the thin-walled female die and larger than the diameter of the inner hole of the thin-walled female die. The positioning hole and the jig body are axially concentric, the positioning hole and the thin-walled female die are in close sliding fit, the thin-walled female die is pressed into the positioning hole through the pressing plate, the problem that the thin-walled female die is damaged due to the fact that the thin-walled female groove is directly clamped by a three-jaw chuck is avoided, all that is needed is to guarantee the straightness and the concentricity of the jig body during machining, the inner hole of the thin-walled female die can be machined, operation is simple and convenient, and the work efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of tool, particularly relate to a kind of interior hole machined tool of thin-walled die.
Background technology
Die, punch are the kernel components in cold punching die industry.At present, at air-conditioner fin die, the quantity of die, punch is very huge, and in every secondary mould, the quantity of die, punch on average wants thousands of many covers.As shown in Figure 1, for the structural representation of air-conditioner fin die thin-walled die, its endoporus is the through hole run through, during the interior hole machined of this thin-walled die existing, scroll chuck is adopted directly to clamp thin-walled die, concentricity and the linearity that part guaranteed by table is beaten again with μ table, finally use the grinding head dedicated processing endoporus of endoporus, but, this kind of processing method, often process a thin-walled die, once table is played with regard to needs, complicated operation, efficiency is lower, and due to the wall of thin-walled die thinner, be generally 3 ~ 4mm, adopting scroll chuck directly to clamp easily causes it to damage, thus, be badly in need of solving.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of interior hole machined tool of thin-walled die is provided, scroll chuck is directly adopted to clamp thin-walled die to solve hole machined in existing thin-walled die, easily cause the problem that thin-walled die damages, and hole machined adopts scroll chuck directly to clamp in existing thin-walled die, often a processing thin-walled die need be beaten and once show, complicated operation, inefficient problem.
The object of the invention is to be achieved through the following technical solutions:
A kind of interior hole machined tool of thin-walled die, comprise jig body, one end of described jig body axis has hole, and the other end of its axis has the locating hole be connected with hole, the aperture in described hole is less than the external diameter of thin-walled die, described locating hole is axially concentric with jig body, and locating hole and thin-walled die form close working fit, described jig body has the dismountable pressing plate be connected with for compressing thin-walled die in one end of locating hole, described pressing plate has spacing hole, the aperture of described spacing hole is less than the external diameter of thin-walled die, and the aperture of spacing hole is greater than the aperture of thin-walled die endoporus.
As a preferred embodiment of the present invention, the outer wall that described jig body has locating hole one end is provided with external screw thread, the non-one end having spacing hole of described pressing plate has fixing hole, described fixing hole is connected with spacing hole, and the inwall of fixing hole is provided with the internal thread matched with described external screw thread; There is the feature of convenient disassembly.
As a preferred embodiment of the present invention, the outer wall of described pressing plate is provided with annular knurl; Be convenient to screw.
Beneficial effect of the present invention is, the locating hole of the interior hole machined tool of described a kind of thin-walled die is axially concentric with jig body, and locating hole and thin-walled die form close working fit, and by pressing plate, thin-walled die compression is positioned in locating hole, avoid because scroll chuck directly clamps the problem that thin-walled die causes thin-walled die to damage, and add man-hour, only need ensure linearity and the concentricity of jig body, the interior hole machined of thin-walled die can be carried out, simple, convenient, substantially increase operating efficiency.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.Be understandable that, embodiment described herein is only for explaining the present invention, but not limitation of the invention.
Please refer to shown in Fig. 2 and Fig. 3, Fig. 2 is the structural representation of the interior hole machined tool of a kind of thin-walled of the present invention die; Fig. 3 is the interior hole machined tool using state structural representation of a kind of thin-walled of the present invention die.
In the present embodiment, a kind of interior hole machined tool of thin-walled die, comprise jig body 1, the left end of described jig body 1 axis has hole 2, and the right-hand member of its axis has the locating hole 3 be connected with hole 2, the aperture in described hole 2 is less than the external diameter of thin-walled die, described locating hole 3 is axially concentric with jig body 1, and locating hole 3 and thin-walled die form close working fit, the right-hand member of described jig body 1 has been threaded pressing plate 4, the outer wall of described pressing plate 4 is provided with annular knurl, the left end of pressing plate 4 has the fixing hole 5 matched with jig body 1, the inwall of described fixing hole 5 is provided with internal thread 6, the outer wall of described jig body 1 right-hand member is provided with the external screw thread 7 matched with this internal thread 6, the right-hand member of described pressing plate 4 has spacing hole 8, the aperture of described spacing hole 8 is less than the external diameter of thin-walled die, and the aperture of spacing hole 8 is greater than the aperture of thin-walled die endoporus.
Add man-hour, first jig body 1 is fixed on the scroll chuck of grinding machine, linearity and the concentricity that table ensures jig body 1 is beaten with μ table, then thin-walled die is loaded in the locating hole 3 of jig body 1, external diameter due to thin-walled die is greater than the aperture in jig body 1 hole 2, thus make thin-walled die slide into the right-hand member termination in hole 2 only, again pressing plate 4 is screwed the right-hand member in jig body 1, aperture due to pressing plate 4 upper limit hole 8 is less than the external diameter of thin-walled die, and the aperture of spacing hole 8 is greater than the aperture of thin-walled die endoporus, thus thin-walled die pushed down by pressing plate 4, play spacing fastening effect, now namely the endoporus of available dedicated inner bore grinding head to thin-walled die is processed, after machining, unclamp pressing plate 4 and take out thin-walled die, load next thin-walled die, tighten pressing plate 4, now without the need to playing table and capable of direct processing, easy to operate, efficiency is high, substantially increase crudy and the efficiency of batch thin-walled die.
Above embodiment has just set forth general principle of the present invention and characteristic; the present invention does not limit by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
