Abstract
The utility model discloses a thermal deformation fixture for thermal treatment of a toothed sleeve, which is formed by a positioning end and a compensating section. An oil passing hole is arranged on the thermal deformation fixture. In the thermal treatment of the toothed sleeve, the thermal deformation fixture is positioned on a relatively thinner first section on the toothed sleeve through the positioning end, and the thinner first section is compensated through the compensating section extending in the first section of the toothed sleeve, thereby enabling the heating speed and the cooling speed of the first section and a second section different in thickness on the toothed sleeve to be basically identical, greatly reducing out-of-tolerance of the taper and enabling the taper qualified rate to reach 95%.
Description
Technical field
The utility model relates to a kind of thermal treatment and uses anchor clamps, refers to that especially a kind of tooth that is used for overlaps heat treated thermal distortion anchor clamps.
Background technology
Usually the shape of tooth cover is similar to cylindrical drum, is provided with tooth at the inwall of cylindrical drum, is called internal tooth, and some tooth is enclosed within and all is provided with tooth on the inside and outside cylindrical wall.The general technology manufacturing procedure of tooth cover is: forging material blanking → mechanical workout is the inside and outside tooth → thermal treatment of cylindrical drum → mechanical workout.Some tooth cover shape more complicated, it is became uneven even (promptly having a thick end and a thin end) up and down, during thermal treatment; Heating, speed of cooling is different; Cause occurring the overproof situation of tapering, what promptly the thin end of tooth cover shrank manyly, thick end shrinks lacks, and causes the tooth cover loudspeaker shape to occur.Tapering can characterize with M value (space width span), is that tapering is defective with the poor >=0.10mm of the thick end of tooth cover and the M value of thin end, and the tooth of became uneven is enclosed within prior heat treatment operation tapering disqualification rate afterwards and can reaches 80% up and down.
The utility model content
In order to overcome above-mentioned defective; The utility model provides the thermal treatment of a kind of tooth cover to use the thermal distortion anchor clamps; Appearance was tubaeform after the thermal treatment of this tooth cover can effectively reduce and control tooth and be enclosed within thermal treatment with the thermal distortion anchor clamps, and the tapering qualification rate that makes tooth be enclosed within after the thermal treatment reaches 95%.
The utility model for the technical scheme that solves its technical problem and adopt is:
The thermal distortion anchor clamps are used in the thermal treatment of a kind of tooth cover; Said tooth cover has relative two sections and is respectively first section and second section; Said second section thickness is benchmark greater than said first section thickness with said thermal distortion anchor clamps direction in use, and said thermal distortion anchor clamps are made up of with the columniform compensator section that is positioned at the bottom is one-body molded the positioning end of superposed circle; And said positioning end and said compensator section are positioned on the same geometric axis; Said positioning end can be positioned first section of said tooth cover, and when said positioning end was positioned first section of said tooth cover, said compensator section was positioned at said tooth and overlaps; Offer oil-through hole on the said thermal distortion anchor clamps; Said oil-through hole is that through hole and above-below direction run through said positioning end and said compensator section, and the spacing of the internal tooth point circle of the periphery of said compensator section and said tooth cover is 2～3 millimeters, and the height of said compensator section is identical with first section height of said tooth cover.The tooth cover is being carried out in the heat treated process; Through positioning end the thermal distortion anchor clamps are positioned tooth and put relatively thin first section; Come thin first section is compensated through stretching into compensator section in first section in the tooth cover, the oil-through hole that tooth puts can make cooling oil pass through.
The utility model for the further technical scheme that solves its technical problem and adopt is:
Preferably, said oil-through hole is opened in the central authorities of said thermal distortion anchor clamps.
Preferably, said oil-through hole is that connection constitutes and the cross section is the through hole of reversed convex type with following cylindrical hole one by last cylindrical hole.
Preferably, the said diameter of cylindrical hole down is 15～20 millimeters.
Preferably, said compensator section is positioned at that said to go up the peripheral wall thickness of cylindrical hole be 10～15 millimeters.
The beneficial effect of the utility model is: the utility model provides the thermal treatment of a kind of tooth cover to use the thermal distortion anchor clamps; Constitute by positioning end and compensator section; The tooth cover is being carried out in the heat treated process; Through positioning end the thermal distortion anchor clamps are positioned tooth and put relatively thin first section, come thin first section is compensated, make tooth put thickness different first section and second section heating, speed of cooling basically identical through stretching into compensator section in first section in the tooth cover; Significantly reduce the overproof situation of tapering, the tapering qualification rate can reach 95%.

Embodiment
Embodiment: the thermal distortion anchor clamps are used in the thermal treatment of a kind of tooth cover; Said tooth cover A has relative two sections and is respectively first section A1 and second section A2; Said second section thickness is benchmark greater than said first section thickness with said thermal distortion anchor clamps B direction in use, and said thermal distortion anchor clamps B is made up of with the columniform compensator section B2 that is positioned at the bottom is one-body molded the positioning end B1 of superposed circle; And said positioning end and said compensator section are positioned on the same geometric axis; Said positioning end can be positioned first section of said tooth cover, and when said positioning end was positioned first section of said tooth cover, said compensator section was positioned at said tooth and overlaps; Offer oil-through hole B3 on the said thermal distortion anchor clamps; Said oil-through hole is that through hole and above-below direction run through said positioning end and said compensator section, and the spacing of the internal tooth point circle of the periphery of said compensator section and said tooth cover is 2～3 millimeters, and the height of said compensator section is identical with first section height of said tooth cover.
Said oil-through hole is opened in the central authorities of said thermal distortion anchor clamps.
Said oil-through hole is by last cylindrical hole B31 and the connection of following cylindrical hole B32 one constitutes and the cross section is the through hole of reversed convex type.
The said diameter of cylindrical hole down is 15～20 millimeters.
It is 10～15 millimeters that said compensator section is positioned at the said wall thickness of going up the cylindrical hole periphery.
