Specific embodiment
Below by the drawings and the specific embodiments, the invention will be further described.
As illustrated in figs. 1A and ib, contracting than caliper include right caliper body 1, left caliper 2, lock-screw 3, load piston 4 and
Sealing ring 5, left sample mounting blocks 6, right sample mounting blocks 10.Wherein right caliper body 1 is L shape, and left caliper 2 is located at the L-type of right caliper body 1
Inside.
As shown in Figure 1 b, on the lower contact surface of the horizontal direction plate face of the L-shaped structure of right caliper body 1, along left and right caliper phase
Boss 15 is machined with to mobile direction, corresponding processing fluted 16 on the upper contact surface of left caliper 2, groove is equally along left and right
The direction processing of caliper relative movement, boss 15 and groove 16 carry out assembly cooperation positioning, so that left and right caliper 1,2 relatively moves
When can accurately position.
Intermeshing rack gear 11 is processed on left and right caliper 1,2 contact surfaces, in the horizontal plate face of right caliper body 1 and left caliper 2
Screw hole is processed, according to the faying face of the adjustable rack gear 11 of the thickness of various sample to reach best position, when left pincers
When optimum position is arrived in body 2 and the relative movement of right caliper body 1, by 3 locking positioning of screw hole and lock-screw, with strengthen rigidity.
The inside of left caliper 2 is machined with piston/cylinder 12, passes through the sealing installation load piston of sealing ring 5 in piston/cylinder 12
4, left sample mounting blocks 6 are fixedly mounted in the outer end of load piston 4, and as shown in Figure 1a, the width of left sample mounting blocks 6 is greater than piston
The width of cylinder body 12, therefore load piston 4 seals in piston/cylinder 12 along loading direction when moving, and left sample can be allowed to pacify
Dress block 6 is stuck in except piston/cylinder 12.Left friction sample 8 is fixed by the installation of left sample mounting blocks 6.
In order to drive load piston 4 on left caliper 2 mobile, 3 threaded holes are processed on left caliper 2, keep it convenient with
Brake caliper mounting bracket on testing stand slide unit is connected, and hydraulic braking pipe is installed by quick-release connector, with the hydraulic of certain pressure
Oil enters piston/cylinder 12 by threaded hole, and load piston 4 is pushed to be moved to the left under the action of hydraulic oil.
Right sample mounting blocks 10 are co-axially mounted on the inside of the vertical plate face of L-type of right caliper body 1, with left sample mounting blocks 6, the right side is rubbed
Sample 9 is wiped to fix by the installation of right sample mounting blocks 10, and make left friction sample 8 and above-mentioned right friction sample 9 coaxial etc.
It is high.
Frictional disk 7 is located between above-mentioned left friction sample 8 and above-mentioned right friction sample 9.The position of three is adjusted, it is real
The now adjusting of left and right frictional force.
Left sample mounting blocks 6 and right sample mounting blocks 10 in the present apparatus are designed by special structure, according to test block ruler
The design of little progress row structure can be reliably fixed contracting than sample by transition fit, not only facilitate processing and installation, but also can realize load
Sliding meets contracting than friction test requirement.
As shown in Fig. 1 b and Fig. 2, the position that sample is installed among left sample mounting blocks 6 is in rectangle, and each pointed part is equal
There is fillet excessive, facilitate processing and installation sample, process shoulder 13 before and after the upper end of outer wall, in connecing accordingly for left caliper 2
Sliding slot 14 is processed in contacting surface, shoulder 13 and sliding slot 14 match, and left sample mounting blocks 6 are moved along the direction of sliding slot
It is dynamic.
As shown in Fig. 1 b and Fig. 3, the position of the right same intermediate installation sample of sample mounting blocks 10 is in rectangle, each corner
Dividing has fillet excessive, facilitates processing and installation sample, but it is equipped with 2 mounting holes above, passes through screw and right caliper body 1 connects
It connects.
