Abstract
The invention relates to a quick change tool for replacing a deep hole thimble of a hobbing die. The quick change tool for replacing the deep hole thimble of the hobbing die comprises a casing; one end of the casing is connected with a handle while the other end is connected with a sleeve; a sleeve hole of the sleeve is a quadrangle hole matched with the deep hole thimble; V-shaped lugs raised into the hole are respectively arranged at four positions at corners of every two adjacent side surfaces in the quadrangle hole; the side surfaces of the V-shaped lugs are detaching contact surfaces and the other side surfaces of the V-shaped lugs are mounting contact surfaces; the end surface, corresponding to the four detaching contact surfaces, of the sleeve is provided with four U-shaped rising pin fixing slots; a rising pin is fixed in each rising pin fixing slot; the axial directions of the rising pins and the radial direction of the sleeve are in the same direction. When the quick change tool is used for detaching, the sleeve end of the quick change tool extends into the hobbing die and sleeves the thimble, the four side surfaces at the lower part of the thimble are respectively in contact with the rising pins at the four detaching contact surfaces, and the thimble is detached from the hobbing die by rotating the handle counterclockwise; during mounting, the sleeve sleeves the thimble, and the thimble can be mounted into the hobbing die by rotating the handle clockwise.
Description
Technical field
The invention belongs to Machining Technology field, be specifically related to the quick-change tool for changing gear hobbing Molded Depth hole thimble.
Background technology
Longaxones parts adds man-hour carrying out gear-hobbing machine external splines, conventionally adopts major axis vertical direction to place, and lower end is fixing with gear hobbing mould location, and upper end is with tail stock for machine tool thimble location.Because major axis series products is more, different in size, use same secondary mould positioning and clamping, due to length difference, use same die ejector pin, long or the too short machine tooling scope that all can exceed of workpiece, causes a series of products of a kind of gear hobbing mould within the scope of can only processing length, cannot locate processing to the product that exceedes length range.Existing gear hobbing model point is: accurate positioning, and realize long axis workpiece two ends centre bore and adopt two thimble location, ensure external splines and each grade of cylindrical concentricity of major axis, improve the quality of products.Shortcoming is: number of molds is too much, due to longaxones parts specification disunity, and different in size causing, the corresponding a kind of mold base of a kind of specification product, causes mould more.In production, number of molds is too much, is not easy to management maintenance.Change product more difficult, because of a kind of corresponding die holder of thimble of specification, die change adopts whole die holder to change and adjusts, and thimble cannot be changed separately.Die holder entirety is heavier, needs again to beat table centering after replacing, general 20～30 minutes of time.
Summary of the invention
The thimble of gear hobbing mould adapted different length, the major axis series products different in size that can solve some adds a shared gear hobbing mould in man-hour; In order to solve the handling problem of thimble, the invention provides a kind of for changing the quick-change tool of gear hobbing Molded Depth hole thimble.
Comprise sleeve pipe for the quick-change tool of changing gear hobbing Molded Depth hole thimble, one end of sleeve pipe is connecting handle, and the other end is connecting sleeve; The quadrilateral hole that the cylinder Kong Weiyu deep hole thimble of described sleeve coordinates, is respectively equipped with the V-arrangement projection to hole internal projection between adjacent two sides everywhere in quadrilateral hole, and a side of described V-arrangement projection is dismounting contact-making surface, and another side is for installing contact-making surface; Offer the pin holddown groove that hoists of four U-shapeds with the end face of four sleeves corresponding to dismounting contact-making surface, in each pin holddown groove that hoists, be fixed with respectively the pin that hoists, and the pin that hoists axially and sleeve radially in same direction;
While being used for dismantling, the socket end of quick-change tool stretches in gear hobbing mould, is enclosed within on thimble, the pin contacts that hoists at contact-making surface places is dismantled with four respectively in four sides of thimble bottom, rotate counterclockwise handle, the pin that hoists screws in the basifacial arc groove of four sides, thimble can be disassembled in gear hobbing mould; When installation, jacket casing is on thimble, and four sides of thimble bottom contact with described four installation contact-making surfaces respectively, clockwise rotate handle and thimble can be packed into gear hobbing mould.
Four sides in described quadrilateral hole are the cambered surface of same curvature radius.
Useful technique effect of the present invention embodies in the following areas:
1. quick-change tool is simple in structure, can realize quick joining with thimble.Sleeve pipe adopts hollow-core construction, reduces to greatest extent quick-change tool weight; Sleeve is installed arcwall face transition between contact-making surface and dismounting contact-making surface, and while guaranteeing thimble installation and removal, quick-change tool can steadily turn round, and realizes two contact-making surfaces and switches fast; Hoist pin and thimble arc groove fit form is simple and direct, can realize that quick-change tool is connected fast with thimble, separation;
2. simple operation, casing length directly makes up the degree of depth that manually cannot touch, realizes the replacing of the required thimble of different length workpiece;
3. solve deep hole and cannot change a difficult problem for thimble, facilitated mold management, cost-saving.
