Description
Technical field
The invention belongs to jig field, adds more specifically to a kind of the constant of material abrasion resistance properties of measuring and monitoring the growth of standing timber
Carry power jig.
Background technology
With the rapid development of material science and machinery manufacturing industry, increasing new material is used for machinery manufacturing industry
In, and the abrasion resistance properties of material are the important indicators of a measurement material combination property, are surveyed in production practices for quick
The requirement for determining material wear-resistant damage performance is also increasingly urgent.
Current market sales of frictional wear experiment equipment mostly external import, it is expensive, and testing process is complicated,
Special messenger is needed to operate, either material properties test or post facility maintenance is required for larger cost.The deficiency for more than, we
Devise it is a kind of rely on junior machine can quickly, the constant load power of reliable, low cost test material abrasion resistance properties
Jig.Between machine tool grinding head and tested sample using universal joint be flexibly connected, not only ensure that test effect accuracy but also
Generation rigidity causes damage to mill to machine tool accuracy between machine tool grinding head can be avoided and treat test sample.
The content of the invention
For existing deficiency, problem to be solved by this invention is, to being tested trial work by the way of pulley counterweight counterweight
Part applies the power of a fixed size straight up so that a kind of tested workpiece grinding shape in constantly acting load in test
State, it is flexibly connected between workpiece and bistrique using universal joint, ensures that workpiece is soft in one kind all the time with bistrique in test process
Property grinding status, avoid occurring therebetween rigidity and mill caused damage to lathe.
To solve the above problems, the present invention adopts the following technical scheme that.
A kind of constant load power jig for material abrasion resistance properties of measuring and monitoring the growth of standing timber, including clamping fixture seat, in addition to guide rail, holder
Platform, joint collet connector, fastening bolt, bistrique, clamping device, loading device, the lower end of described guide rail are connected with clamping fixture seat,
It is welded and fixed using cold welding；Described holder platform is sleeved on four guide rails, can be slided up and down on guide rail；Joint collet connector
Upper end connecting machine tool chuck lower end connecting test bistrique；Fastening bolt is used for fixed test bistrique；Clamping device is revolved by screw thread
Turn to clamp measured workpiece；Loading device is fixed on clamping fixture seat, and weights are connected by pulley through rope with holder platform, with
This applies load to workpiece.
Described guide rail and holder platform keeps therebetween certain gap to coordinate, and ensures that holder platform can be on guide rail freely
Slide.
The gravity of weights is converted into by the loading force of workpiece by described loading device by fixed pulley.
Compared to prior art, beneficial effects of the present invention are：
It can apply different size of power, under identical bistrique, lathe to workpiece for measurement by the weights of different weight
In the case that rotating speed is certain, the time is ground using identical, the wear extent weight of measured workpiece is gathered, according to the big of wear extent
It is small, the abrasion resistance properties of workpiece can be quickly determined, simple to operate, cost is cheap, passes through between machine tool grinding head and test piece
Universal joint is flexibly connected, that is, be ensure that the accuracy of test effect and can be protected the precision of machine tool again.

Embodiment
Embodiment：Potsherd abrasion resistance properties are tested
Material and equipment are as follows：
Potsherd 30mm × 30mm × 6mm；
Both ends counterweight counterweight is 10N, and total loading force is 20N；
The small-sized diy engraving machines of doctor Lin 3D；
Associate b470 notebook computers；
Diamond disk φ 10mm；
The fixture of the present invention；
Electronic balance；
Process：
Present clip is secured by bolts in the machine table of engraving machine first；Then weighed to be tested
Potsherd is lain on holder platform, is tightened clamping device upper end swivel bolt and is fixed；Universal joint upper end is connected to engraving
Machine grip holder, lower end connection φ 10mm diamond disks, mill are fixed on joint collet connector lower end by fastening bolt；Manipulate carving
Quarter machine, drop to diamond disk and just contacted with potsherd；Counterweight 10N counterweight, holder platform are respectively placed at pulley both ends
It is pulled up, realizes the loading of potsherd；Engraving machine speed of mainshaft 5000r/min is set, and main shaft rotates forward, and timing starts, during grinding
Between be 15min, pass hull closure is removed potsherd and weighed again, measures the wear extent of potsherd；Pass through the mill of potsherd in 15min
Damage amount weighs the abrasion resistance properties of the potsherd.
