Description
Technical field
The utility model is related to a kind of lapping device, more particularly to surface grinding testing machine.
Background technology
In order to study gradient nano material, it is necessary to be surface-treated to material using the technological means of surface grinding,
For the making milling apparatus of more accurate more system, it is necessary to first obtain some basic technological parameters.
Existing surface grinding technology is generally controlled using Digit Control Machine Tool, and the equipment cost for being used is very high, big material
Small use.
The content of the invention
It is to solve the deficiencies in the prior art, there is provided a kind of surface grinding testing machine, this rub tester is rational in infrastructure, make
With conveniently.
To achieve the above object, the utility model uses following technical scheme：
Surface grinding testing machine includes base, and one group of relative bearing block is fixed with base, and bearing opposite end is installed
There is the shaft coupling for clamping test pieces, wherein opening up the hole coordinated with spanner in a bearing rotating shaft；Be fixed with base with
This group of bearing block axis vertical the first support base and the second support base；Drive rod is arranged on the first support base by linear bearing
On, drive rod front end is provided with grinding head；Push rod is installed, push rod is slidably connected with the second support base, pushes away on the second support base
Rod rear end is fixedly connected with screw mandrel, and screw mandrel is threadedly coupled with the second support base；It has been connected through a screw thread between push rod and drive rod
Twin-screw pressure sensor.
Twin-screw pressure sensor is a commercial standard part, and its two ends carries connection screw thread, and middle part is pressure sensor.
The utility model is fed by screw mandrel can apply different pressure to sample, while can be obtained by handy spanner
The minimum torque materialsed needed for overcoming minimum friction, is easy to the type selecting of lathe motor.The recessed of sample is measured after taking out sample
Hole pattern, can obtain the grinding depth under different pressures, be easy to determine feeding depth during lathe process.
By this rub tester of the utility model, test surfaces grind required minimal torque, grinding effect etc.,
So that the low cost lathe such as engine lathe, small size lathe can also realize surface grinding function.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.

Specific embodiment
Referring to the drawings,
Surface grinding testing machine includes base 1, and one group of relative bearing block 31,32 is fixed with base, and bearing is relative
End is provided with the shaft coupling 4 for clamping test pieces, wherein opening up the hole coordinated with spanner 21 in a bearing rotating shaft 33；In base
On be fixed with first support base 61 and second support base 62 vertical with this group of bearing block axis；Drive rod 5 passes through linear bearing
52 are arranged on the first support base, and drive rod front end is provided with grinding head；Push rod 8, push rod and are installed on second support base
Two support bases are slidably connected, and putting back-end is fixedly connected with screw mandrel 9, and screw mandrel is threadedly coupled with the second support base；Push rod and driving
Twin-screw pressure sensor 7 has been connected through a screw thread between bar.
Shaft coupling can be used to match the sample of different-diameter from different models, and by can as shaft coupling
Assembly connection, can be in order to the dismounting of sample and installation.
Drive rod is arranged on the linear bearing of support base, it is ensured that linearity when drive rod is moved.Reduce bending.
Pole sample is arranged between the shaft coupling of the bearing block for setting relatively, rotary screw, grinding head insertion pole
Sample certain depth, measures sample and overcomes tangential friction force and rotate by the torque spanner installed in the rotating shaft that is connected with sample
Required minimum torque, the tangential friction force according to suffered by moment equilibrium condition calculates pole sample is measured by pressure sensor
Transverse pressure suffered by sample, and then average friction coefficient is calculated by Coulomb friction law, using super depth-of-field microscope to pit
Pattern carries out three-dimensional digitized measurement, finally gives critical torque, tangential friction force, transverse pressure, average friction coefficient and recessed
The information such as hole pattern.
Additionally, in order to study influence of the different grinding head shapes to compression distance, can be carried out to the head of drive rod
Repacking, obtains cylinder, and spherical, the various grinding heads such as taper, then using above-mentioned same method, obtain correspondence under the grinding head
Some parameters.
This example is using WC/Co grinding heads, i.e. diamondite steel ball grinding head, with suitable hardness and grinding spy
Property.
