Abstract
The utility model relates to a hardness detection jig of thermal treatment rod parts. The hardness detection jig is characterized in that the hardness detection jig comprises a chassis, a plurality of fixed shafts fixedly arranged on the chassis, gears and cams, the gears and the cams are connected with the fixed shafts in a moving-matched mode, and the chassis is further provided with inner gear rings meshed with a plurality of gears in a moving-matched mode. The hardness detection jig has the advantages that rod parts can be fixed in a hardness instrument through the jig for end face hardness detection, the inner gear rings can rotate on the chassis, so that three symmetrical gears rotate synchronously, the cams are fixed on the gears, the eccentric error e exists between the center of each round cam and the center of each gear, when the inner gear rings rotate in the forward and backward directions, the cams can clamp or loose the rod parts, and the jig is compact in structure, convenient to operate, safe, reliable, large in clamping range, long in service life, and the like.
Description
Technical field
The utility model belongs to heat treatment and detects the apparatus technical field, particularly relates to a kind of heat treatment component of rod category hardness and detects fixture.
Background technology
At present, after heat treatment, its end hardness detects and usually adopts manual righting to be placed on the chassis of hardness tester component of rod category, and its end face is carried out to the hardness detection.This detection mode exists the incorrect and hardness in rod member location to detect the defects such as inaccurate.When the component of rod category run-off the straight, may cause and skid off and jump from phenomenon, bring unsafe factor to the operator.In addition, also having some component of rod category hardness to detect fixture is special fixture, only can adapt to single rod member and detect use, and the scope of application is restricted.
Summary of the invention
The utility model provides a kind of safe and reliable, applied widely and easy to operate heat treatment component of rod category hardness to detect fixture for solving the technical problem existed in known technology.
The technical scheme that the utility model is taked for the technical problem existed in the solution known technology is:
Heat treatment component of rod category hardness detects fixture, comprises chassis, is packed in a plurality of fixed axis and the gear be connected movingly with fixed axis and cam on chassis, and the ring gear be meshed with a plurality of gears also is housed on described chassis movingly.
The utility model can also adopt following technical scheme:
3 fixed axis are housed on described chassis, on described each fixed axis, are connected with movingly gear and cam.
Described 3 fixed axis are 120 ° and are arranged symmetrically with, and the gear on fixed axis and cam are mutually fastening by screw.
Described fixed axis is connected by jackscrew and chassis, in the fixed axis upper end, is provided with check ring.
Two handles have been threaded on described ring gear cylindrical.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, by this fixture, component of rod category can be fixed in hardness tester, carry out the end hardness detection.Ring gear can be at the chassis upper rotary, and the revolution of ring gear makes three symmetrical gear synchronous rotations, is fixed wtih cam on gear, and circular cam center and gear centre have certain centering error e.When the ring gear both forward and reverse directions turns round, can realize cam to the clamping of rod member or unclamp.This fixture has compact conformation, easy to operate, safe and reliable, gripping range reaches greatly the advantages such as long service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
In figure: 1, chassis; 2, fixed axis; 3, jackscrew; 4, handle; 5, ring gear; 6, gear; 7, circlip; 8, screw; 9, cam; 10, rod member.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, heat treatment component of rod category hardness detects fixture, comprise chassis 1, be packed in a plurality of fixed axis 2 and the gear 6 be connected movingly with fixed axis and cam 9 on chassis, the ring gear 5 be meshed with a plurality of gears also is housed on described chassis movingly.In the present embodiment, 3 fixed axis 2 are housed on described chassis, described 3 fixed axis 2 are 120 ° and are arranged symmetrically with, and are connected with movingly successively from the bottom to top gear and cam on described each fixed axis, and the gear on fixed axis and cam are mutually fastening by screw 8.The lower end seam of described ring gear is connected with chassis cylindrical matched in clearance, and with three gear 6 engaged transmission.
Described fixed axis is connected by jackscrew 3 and chassis, is provided with the check ring 7 that plays the axial location effect in the fixed axis upper end.
On described ring gear 5 cylindricals, screw thread is symmetrically connected with two handles 4.
Operation principle of the present utility model is:
Component of rod category can be fixed in hardness tester by this fixture, carry out the end hardness detection.As shown in Figures 1 and 2, ring gear can be at the chassis upper rotary for its structure, and the revolution of ring gear makes three symmetrical gear synchronous rotations, is fixed wtih cam on gear, and circular cam center and gear centre have certain centering error e.When the ring gear both forward and reverse directions turns round, can realize cam to the clamping of rod member or unclamp.
