Abstract
The utility model discloses a thermal treatment tool clamp for rod-shaped components with a high slenderness ratio. The thermal treatment tool clamp comprises a bearing clamp, an upper open slot, a lower open slot, clamping rod insertion holes and horizontal circular positioning clamping rods, wherein the upper open slot is arranged on the center at the upper end of the bearing clamp and used for bearing workpieces; the lower open slot is arranged on the center at the lower end of the bearing clamp and used for bearing the workpieces in a penetrating manner; the clamping rod insertion holes are formed between the upper open slot and the lower open slot; the horizontal circular positioning clamping rods are inserted in the clamping rod insertion holes in a penetrating manner and used for vertically positioning the workpieces. The horizontal circular positioning clamping rod are horizontally inserted into the two clamping rod insertion holes of the bearing clamp, respectively, and a gap between the horizontal circular positioning clamping rods is a bit greater than the clamping part of the workpieces; when the workpieces are clamped, verticality can be kept when tilting is smaller, so that quenched workpiece deformation due to a fact that workpieces are linearly bent and deformed by quenching and heating while entering the furnace and tilting after being clamped is avoided. The tool clamp disclosed by the utility model lowers amount of finish, and solves phenomena that the slender workpieces are bent and deformed while being quenched before, rate of finished products is low and materials are wasted; besides, the thermal treatment tool clamp is low in manufacturing cost.
Description
Technical field
The utility model relates to the shaft-like part heat-treatment quenching of a kind of big L/D ratio frock clamp.
Background technology
When quench treatment is carried out in shaft-like part thermal treatment to big L/D ratio, for reducing straight line distortion, need to adopt the frock of certain form.General frock clamp can be the pole of punched-plate or two parallel maintenance certain intervals, to realize the hanging carrying to workpiece---and by one end of holding workpiece is hung and erects to heat and quench treatment.But because reason can cause the clamping of workpiece to produce canting (workpiece is hung vertical non-vertical), these reasons may have 1) clamping limb unfairness, especially the frock clamp self-deformation after Reusability of frock clamp; 2) when workpiece is initial in frock, be that clamping is vertical, but after entering heat treatment furnace because of place former of bin thereby cause workpiece and can not keep vertical.The workpiece of large major diameter (if length is in about 100mm, diameter is 3mm) particularly, very little vertical off setting also can be after the quench cooled of 1000 ℃-1200 ℃ of high temperature, and easily there is larger straight line distortion in workpiece.This distortion be under high temperature material occur softening, because self gravitation causes.This distortion causes requirement made allowance when preliminary working more, can make post-treatment extend man-hour, and tooling cost improves.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Zu of dress Fang Bian ﹑ and can reuses, and still can allow workpiece keep vertical when frock or bin have a small amount of canting, is applicable to the shaft-like part fixture for heat treatment of big L/D ratio.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the shaft-like part fixture for heat treatment of a kind of big L/D ratio, comprise carrying fixture, and be arranged on carrying center, fixture upper end for the top fluting of workpiece loading, and be arranged on the bottom fluting that carrying center, fixture lower end screws on for workpiece, and be arranged on the clamping rod patchhole between top fluting and bottom fluting, and be interspersed in the excellent patchhole of clamping for the circular positioning clamping rod of level of workpiece vertically orient.
Further, described carrying fixture is rectangular parallelepiped setting.
Further, the rounded setting in fluting two ends, described top, the rounded setting in fluting two ends, described bottom, fluting two ends, top radius of a circle is greater than fluting two ends, bottom radius of a circle.
Further, the excellent patchhole of described clamping is provided with two, is arranged at carrying two ends, fixture center, and level is through carrying fixture two ends, rounded setting.
Further, the circular positioning clamping rod of described level is provided with two, cylindrical setting, and the identical end of the circular positioning clamping rod of level is provided with thread.
The shaft-like part fixture for heat treatment of a kind of big L/D ratio of the present utility model, comprise carrying fixture, and be arranged on the top fluting that carrying center, fixture upper end screws on for workpiece, and be arranged on the bottom fluting that carrying center, fixture lower end screws on for workpiece, and be arranged on the clamping rod patchhole between top fluting and bottom fluting, and be interspersed in the excellent patchhole of clamping for the circular positioning clamping rod of level of workpiece vertically orient.Top fluting and bottom fluting allow quenchant through fluting, part is carried out fully cooling, while allowing part to load certain limit in carry out vertical direction and automatically adjust, owing to carrying two excellent patchholes of clamping of fixture, be interspersed with respectively the circular positioning clamping rod of level, the clamping part of the Gap-Ratios workpiece between the circular positioning clamping rod of level is slightly large, when workpiece is held, verticality is higher, and while having avoided the oblique clamping of workpiece, quench treatment deforms.Product completes after thermal treatment, and product linearity Gao ﹑ yield rate is high, and following process amount reduces, and cost is low, solved Workpiece carrier non-vertical in the past, the processing of quenching deforms, waste part starting material, yield rate is low, and thermal treatment post-treatment is long man-hour, the problem that cost is high.
