Abstract
The utility model discloses a device for controlling heat treatment deformation of thin wall parts of a gear sleeve and a gear ring. A tray is fixed on the lower end of a bearing shaft; a protection column is installed on the tray; a supporting plate is installed on the protection column; a compensator is installed on the supporting plate. The device for controlling heat treatment deformation of the thin wall parts of the gear sleeve and the gear ring is simple in structure, low in manufacturing cost, convenient to use and high in production efficiency, can be used for lowering the production cost greatly, and is suitable for mass production and use, wherein the production yield can be greater than or equal to 99%.
Description
Technical field
The utility model relates to a kind of machinery processing apparatus, particularly controls the device of thin-walled parts heat treatment deformation.
Background technology
Thin-walled parts such as tooth cover, gear ring through the carbonitriding surface-treated and hardness, intensity improve, have been realized the purpose of surface strengthening, and heart portion still is in the tough state preferably of moulding because of the characteristic of material itself.But the carbonitriding temperature is high, adds that the material interior tissue changes and the influence of composite factor and cause distortion in various degree.Be controlled deformation, the measure taked of industry at present mainly contains: first kind be after the carbonitriding directly or reheat and on the quenching press of special use, carry out press quenching, this kind method exists the investment amount big, running cost is high, the part qualification rate is low; Second kind is that direct quenching after the carbonitriding, tempering are proofreaied and correct, and this method cost of investment is less relatively, but the part qualification rate is very low, is not suitable for producing in batches.
The utility model content
The utility model aims to provide a kind of device of controlling tooth cover, gear ring thin-walled parts heat treatment deformation, less investment, and production efficiency is high, and use cost is low, can increase substantially product percent of pass.
A kind of device of controlling tooth cover, gear ring thin-walled parts heat treatment deformation, pallet is fixed on the bolster lower end, and guard column is installed on the pallet, and supporting plate is installed on the guard column, and loop expansion pipe is installed on the supporting plate.
Further, said guard column has 3 or 4.
Further, said supporting plate has 2-5.
The utility model is simple in structure, and low cost of manufacture is easy to use, and production efficiency is high, can reduce production costs significantly, is fit to produce in batches use, and product percent of pass can reach >=and 99%.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-bolster, 2-supporting plate, 3-guard column, 4-loop expansion pipe, 5-pallet.
Embodiment
As shown in Figure 1, a kind of device of controlling tooth cover, gear ring thin-walled parts heat treatment deformation of the utility model, pallet 5 is fixed on bolster 1 lower end, and guard column 3 is installed on the pallet 5, and supporting plate 2 is installed on the guard column 3, and loop expansion pipe 4 is installed on the supporting plate 2.
Further, guard column 3 can be 3 or 4.Supporting plate 2 has 2-5.
During use, earlier the workpiece seam is put into compensation 4, whole work-piece equality is put into, and the gap should be less than 0.3mm.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
