Abstract
The utility model discloses a device used for processing thin-walled gear ring drawhole. The device comprises a thin-walled gear ring fixing element and a connecting and fixing block used for connecting the thin-walled gear ring fixing element and an operating platform together, the thin-walled gear ring fixing element is of a cylindrical structure, an upper groove matched with the thin-walled gear ring is formed in the thin-walled gear ring fixing element, the depth of the upper groove is lager than the thickness of the thin-walled gear ring to be processed, and a groove is formed in the bottom part; a raised part matched with the bottom part of the thin-walled gear ring fixing element is arranged on the upper part of the connecting and fixing block of the operating platform, and the connecting and fixing block further comprises a through hole. Through adoption of technical scheme, the broaching taper caused by plastic deformation resulting from overlarge deformation of the thin-walled gear ring during the broaching process can be overcome, the broaching stress deformation and taper generation can be effectively controlled, and successive heat treatment technique can be carried out more conveniently; and meanwhile, the device provided by the utility model has the advantages of simple structure, convenience in maintenance and low processing cost, etc.
Description
Technical field
The invention belongs to processing thin-walled gear ring pulling eye field, especially relates to a kind of device for processing thin-walled gear ring pulling eye.
Background technology
Thin-walled gear ring is owing to the unique features that itself has and strict specification requirement, and processing is a difficult point always.In actual production process, thin-walled gear ring often occurs because the distortion that produces in the pulling eye process is excessive and then cause plastic deformation, and distortion is large and inhomogeneous after subsequent heat treatment, the part heat treatment deformation is at all uncontrollable.
Summary of the invention
The problem that the invention will solve provides a kind of device for processing thin-walled gear ring pulling eye, is particularly suitable for processing wall thickness thin-walled gear ring thinner and that quality is had relatively high expectations.
For solving the problems of the technologies described above, the technical scheme that the invention is adopted is: a kind of device for processing thin-walled gear ring pulling eye, the connection fixing block that comprises thin-walled gear ring fixture and connection thin-walled gear ring fixture and operating desk, described thin-walled gear ring fixture is cylindrical structural, inside hollows out the upper groove that is complementary with thin-walled gear ring, the degree of depth of upper groove has a groove greater than the thickness of thin-walled gear ring to be processed on the bottom; The connection fixing block of described operating desk has the protuberance that is complementary with thin-walled gear ring fixture bottom on top, described connection fixing block also comprises a through hole.
Further, described through hole is that two parts form up and down, and the cross section of upper part is greater than lower part cross section.
Further, there is chamfering the both sides of the edge, top of the upper groove of described fixture.
Further, the both sides, upper trench bottom bottom of described fixture also have groove.
Further, described device also comprises a knock-out mechanism, and described knock-out mechanism comprises discharging base plate and ejector pin.Described fixture has the hole that cooperates ejector pin on the bottom.
Owing to adopting technique scheme, overcome thin-walled gear ring because the distortion that produces in the pulling eye process is excessive and then cause the problem of the pulling eye tapering that plastic deformation causes, the effectively generation of control broaching stress deformation and tapering, follow-up Technology for Heating Processing is convenient; The advantages such as simultaneously, the invention has simple in structure, and is easy to maintenance, and processing cost is low.

The specific embodiment
As depicted in figs. 1 and 2, the invention has comprised a thin-walled gear ring fixture, this thin-walled gear ring fixture is a cylindrical structural, in this column structure body, be provided with groove on, the size of upper groove and thin-walled gear ring to be processed are measure-alike, but be greater than the thickness of thin-walled gear ring on the degree of depth, such purpose of design be prevent into cutter end M value out of control.Can also accurately control simultaneously the fit dimension of part outer and frock endoporus.In the both sides, top of upper groove chamfering is arranged respectively in addition, the purpose that is provided with chamfering is to put thin-walled gear ring to be processed in order better to locate, bottom inside at upper groove also has a groove in addition, the purpose of fluting is workpiece to be entered put behind the fixture can more accurately control and the contact angle of upper groove bottom, better cooperate putting of thin-walled gear ring workpiece, be beneficial to the pulling eye operation.
Also have a lower groove in the bottom of fixture, the purpose that has lower groove is in order to be complementary with the connection fixture top of the lathe of described connection fixture and processing work, be used for fixing easily and taking out fixture, side at connection fixture is equipped with through hole in addition, radius surface is greater than lower radius surface on this through hole, consistent with the bolt shape of fixing usefulness, set bolt is fixed together connection fixing block and lathe by this through hole, can better accurately control the thin-walled gear ring process like this, better meet the specification requirement of processing thin-walled gear ring.
In addition, in order better conveniently to take out the thin-walled gear ring of completion of processing from fixture, the invention has also designed a knock-out mechanism, and this knock-out mechanism comprises discharging base plate and ejector pin, and ejector pin can be inserted in the middle of the discharging base plate and be fixed on the discharging base plate.
The use procedure of this example: thin-walled gear ring to be processed is put into the thin-walled gear ring fixture, fixture and contiguous block are connected and fixed, by set bolt fixture and connection fixing block are fixed together with lathe together, then begin to do Wire Drawing, after to be processed the finishing, set bolt is taken out, separate fixture and connection fixing block.Fixture is placed on the knock-out mechanism, takes out the thin-walled gear ring that processes by the extrusion effect of ejector pin on the knock-out mechanism.
An above embodiment to the invention has been described in detail, but described content only is the preferred embodiment of the invention, can not be considered to for the practical range that limits the invention.All equalizations of doing according to the invention application range change and improve etc., all should still belong within the patent covering scope of the invention.
