Abstract
The invention provides a sliding block fixture for a friction coefficient instrument. The sliding block fixture is characterized by comprising a bottom plate (1); a pair of through grooves (1a) are formed in the thickness end face of the bottom plate (1), and a pair of pressing strips (2) correspondingly matched with the pair of through grooves (1a) are further arranged; a support (3) is arranged on the bottom plate (1), and a connecting part (4) correspondingly matched with a detector is further arranged at one end of the support (3). The sliding block fixture has the advantages that the structure is simple, the sample preparing speed is high, operation is easy and convenient, the measuring precision is high, and the sliding block fixture is suitable for measuring the friction coefficients of various plastic packaging films.
Description
Technical field:
The present invention relates to a kind of fixture, be exactly specifically a kind of friction coefficient instrument slide clamp.
Background technology:
Friction coefficient instrument is the instrument for the coefficient of friction and frictional force measuring thin film.Friction coefficient instrument slide block is to measure friction
The very important critical component of coefficient project, friction coefficient instrument utilizes slide block drive between sample and sample or drive sample just
The principle producing frictional resistance with the relative slip of (foundation different product standard) between steel plate measures the coefficient of friction of sample.
According to GB/T 10006-1988 " plastics and thin slice measuring friction coefficient method " testing friction coefficient and the method for frictional force, often
Test procedure be to utilize double faced adhesive tape to be fixed on slide block on the sample cut out, the one side of sample test face is clipped on instrument,
Require the smooth corrugationless of sample.Utilize instrument driving slide block, make two test faces of sample produce and relatively slide, calculate and rub
Wipe coefficient.Or make the sample on slide block produce relative slip with steel plate, calculate coefficient of friction.The quality that sample is fixed is straight
Connect and affect experimental result.Double faced adhesive tape has certain thickness and elasticity, tends at the trial due to the reason of double faced adhesive tape itself
Produce tensile stress and stretching, extension and affect test.The mode of this sample that is adhesively fixed is high to personnel requirement, and be adhesively fixed examination
The tightness of sample, proof stress, folder sample smooth surface degree direct influence are tested, owing to personnel are adhesively fixed sample dynamics handle
The different test datas produced held are the most different, the solution that up to the present industry has not had.
Summary of the invention:
The present invention is contemplated to overcome deficiency of the prior art, it is provided that one has simple in construction, easy to use, and detection prepares
The slide clamp of the plastic friction coefficient instrument that the time is short.
The present invention provides techniques below scheme:
A kind of friction coefficient instrument slide clamp, it is characterised in that: it includes base plate, is provided with a pair and leads on the thickness end face of base plate
Groove, then the press strip of a pair and groove corresponding matching is set；Being provided with a support on base plate, one end of support is additionally provided with and detects
The connecting portion of instrument corresponding matching.
On the basis of technique scheme, it is also possible to have a techniques below scheme:
Described press strip is T-shaped, and press strip is connected by bolt with groove.
The protruding base plate in one end of described support, it is cylindrical for arranging the connecting portion with its end, and described company
The portion of connecing is positioned at plate outer side.
The advantage of invention is:
The present invention has simple in construction, easy and simple to handle, certainty of measurement is high, and self cost of manufacture is cheap, and detection time is short,
The advantages such as the measurement being applicable to various plastic packaging film coefficient of friction.
Accompanying drawing illustrates:
Fig. 1 is the front view of the present invention；
Fig. 2 is the axonometric chart of Fig. 1.
Detailed description of the invention:
As shown in Figure 1, 2, a kind of friction coefficient instrument slide clamp, it includes the base plate 1 arranging a rectangle, in the thickness of base plate 1
It is arranged with a pair groove 1a on degree end face, and the upper and lower surface of the groove bottom of described groove 1a and base plate 1 is mutually perpendicular to.
The T-shaped press strip 2 of a pair and groove 1a corresponding matching is set, described T-shaped press strip 2 is provided with installation screw 2a,
And be connected with groove 1a by T-shaped press strip 2 by bolt, and the lower surface of the end face of T-shaped press strip 2 side and base plate 1 is same
In one horizontal plane.
Arranging a support 3, described support 3 becomes F type, and it includes the quarter butt 3a of two parallel distributions, on quarter butt 3a
End is additionally provided with stock 3b, described stock 3b and is mutually perpendicular to quarter butt 3a, and one end of stock 3b protrudes outwardly to outside base plate 1
Side, is vertically connected with a cylindrical connecting portion 4, described connecting portion 4 and detection at stock 3b on the shaft of end
Instrument corresponding matching connects.
Every quarter butt 3a is provided with countersunk screw holes 5 along its axis, in order to by bolt, support 3 is connected to base plate 1
On upper surface.
Work process:
First the plastics of test are cut into suitable dimension, be laid on the lower surface of base plate 1, and guarantee the plastics of test
Surface does not has fold or curling, the two ends of the plastics of test is then drawn to the upper surface side of base plate 1, then by T-shaped
Press strip 2 is installed in groove 1a, in order to is fixed on base plate 1 by the plastics of test, is not finally shown in figure by connecting portion 4
Detector cooperate together, just can test surfaces to test plastics carry out coefficient of friction detection.
