Abstract
The utility model provides a roller gear thermal treatment special fixture, including the frock frame, the frock frame is put on the shelf and is equipped with the gear support frame, and the support face of gear support frame is that " V " type holds in the palm the face to the bottom of holding in the palm the face in " V " type is equipped with ventilation window, ventilation window's length is less than the length of gear, and the width is less than the diameter of gear, frock frame and gear support frame are that to adopt the material trademark be that ZG20Cr25Ni20Si2's heat resisting steel is made. The utility model discloses because the support face of gear support frame is " V " type, so when roller gear put up up, contact surface between them was line contact or point contact, does not just have the dead angle like this when thermal treatment, can all -round counter gear thermal treatment, make it be heated evenly, guaranteed thermal treatment's quality. Ventilation window's design has made things convenient for hot air cycle.
Description
Technical field
The utility model relates to the thermal treatment of gear, specifically a kind of cylindrical gear thermal treatment unit clamp.
Background technology
Metal heat treatmet is placed in certain medium by metal works to be heated to suitable temperature, and keep certain hour in this temperature after, cool in different media with friction-motion speed again, controlled a kind of technique of its performance by the microstructure changing metal material surface or inside.
And as the processing of gear, thermal treatment is its important step, in order to ensure the quality of gear heat treatment, must use unit clamp.
On existing cylindrical gear thermal treatment Fixture Design, emphasis considers the intensity of frock, causes frock weight to lay particular stress on, and because frock combines by multiple assembly, when loading and unloading gear, need artificial unloading's assembly, labour intensity is large.
When heating in stove, frock occupies larger space simultaneously, adds energy consumption, and warm air circulation is simultaneously not smooth, and cause gear local heating uneven, quality is unstable.
As shown in Fig. 5,6,7,8, in figure, 1 is frock framework; 2, gear support frame; 3 is gears, and wherein the circular arc support 4 of gear support frame 2 is arc-shapeds, is provided with the ventilation opening 5 of 25mm in the bottom of support; The bottom of gear support frame 2 is provided with the limited block 6 coordinated with frock framework 1, is connected in frock framework 1 to facilitate by gear support frame 2; When thermal treatment, gear 3 is directly placed on the circular arc support 4 of the arc-shaped of gear support frame 2, now due to the plane-plane contact of gear and arc surface, will cause heat treated uneven, simultaneously the ventilation opening 5 of 25mm is comparatively slow in heat radiation hourly velocity, dispels the heat unevenly also can cause gear 3 thermal effectiveness.
Summary of the invention
The utility model causes the defective of quality product to solve the uneven of cylindrical gear thermal treatment, simultaneously also energy-conservation, reduce labour intensity, special a kind of cylindrical gear thermal treatment unit clamp is proposed.
The technical solution of the utility model for this reason: a kind of cylindrical gear thermal treatment unit clamp, comprise frock framework, frock framework is added is provided with gear support frame, it is characterized in that: the support of gear support frame is " V " type support, and is provided with ventilation window in the bottom of " V " type support.
Further improvement is: the length of ventilation window is less than the length of gear, and width is less than the diameter of gear.
Further improvement is: frock framework and gear support frame adopt material mark to be that the high temperature steel of ZG20Cr25Ni20Si2 is made.
Beneficial effect:
The utility model due to the support of gear support frame be " V " type, so when Cylinder Gear wheel carrier gets on, both contact surfaces are linear contact lay or point cantact, just dead angle is not had like this when thermal treatment, can be comprehensive to gear heat treatment, make it be heated evenly, ensure that heat treated quality.The design of ventilation window facilitates hot air circulate.
The design of ventilation window, to ensure unsettled on gear support frame of gear, makes the unsettled of its maximum range, to ensure the heating surface area of gear; Enable gear thermally equivalent; Rate of heat exchange substantially increases, and gear is heated more even, directly enhances heat treated quality, alleviates the weight of frock, reduces workman at the labour intensity loading and unloading frock and workpiece.
Heat-treatment part frock uses high temperature steel, and material mark is ZG20Cr25Ni20Si2, can reuse, and light-weight design inherently greatly reduces frock manufacturing cost.

Embodiment
The utility model as shown in Figure 1,2,3, 4.
A kind of cylindrical gear thermal treatment unit clamp, comprise frock framework 1, frock framework 1 is added is provided with gear support frame 2, and the support of gear support frame 2 is " V " type supports 7, and versatility is better, and is provided with ventilation window 8 bottom " V " type support 7.
The length of ventilation window 8 is less than the length of gear 3, and width is less than the diameter of gear 3.
Frock framework 1 and gear support frame 2 adopt material mark to be that the high temperature steel of ZG20Cr25Ni20Si2 is made.
During use, frock framework 1 and gear support frame 2 are carried out being assembled into the first layer, the limited block 6 of gear support frame 2 bottom blocks in the space of frock framework 1, it is made not move up and down left and right, again by gear 3 gear support frame 2, the thickness different according to gear, one deck can not put 8--10 not etc., now the first layer is stacked complete, the second layer is put again according to above-mentioned steps, third layer, owing to alleviating frock weight in design, frock manufacturing cost is reduced greatly, design improvement is carried out under the prerequisite of proof strength to gear support frame 2, increase ventilation window 8, improve rate of heat exchange, gear is heated evenly, improve quality product, the use of " V " type support 7 simultaneously, make its versatility better, decrease the contact surface of the flank of tooth and frock thus improve thermal cycling.
