Abstract
A small sample indentation measuring table of a Brinell hardness tester comprises screws, a pressing plate, a V-shaped block, a fixed plate, a fixed block, a ball screw and a body. A body is a cube with two crossed through holes, the body is further provided with a groove communicated with the two crossed through holes, the V-shaped block is connected with the ball screw which is screwed on the fixed block through the fixed block, the V-shaped block and the ball screw are placed in a groove on one sides of the two crossed through holes together, the fixed block is fastened in the groove through the screws, the screws are placed in a groove on the other sides of the two crossed through holes, the pressing plate is fastened on the upper portion of the body through the screws, workpieces to be measured are placed in the crossed through holes and between the V-shaped block and the screws, the ball screw is screwed to push the V-shaped block to move forward or backward, the workpieces can be clamped tightly through the ball screw and the screws, and the pressing plate is used for limiting vertical position of the V-shaped block. The small sample indentation measuring table of the Brinell hardness tester solves the problem of measurement of small sample indentation of the Brinell hardness tester and enlarges application range of instruments.
Description
Technical field:
The utility model relates to field of machining, is specifically related to a kind of Brinell tester and measures the device that impression is used.
Background technology:
The hardness precision that Brinell tester is measured below the HB450 is high.Be commonly used to measure the hardness of annealing, normalizing, modified steel and cast iron, non-ferrous metal.After Brinell tester is accomplished fluently sample, must be placed on and measure impression diameter under the reading microscope, the area of workpiece at least in one direction could reading greater than 30mm.Otherwise can not surely knock off on the part plane in the reading microscope bottom surface, and reading difficult is to carry out.But in the reality, needing the measurement diameter is a lot of less than the situation of the workpiece hardness value of 30mm.
For this reason, the utility model has manufactured and designed the small sample pressure measurement trace platform that a kind of Brinell tester is used.
The utility model content:
The utility model proposes a kind of novel impression platform.Specific as follows:
A kind of Brinell tester small sample pressure measurement trace platform comprises: screw, pressing plate, vee-block, fixed head, fixed block, ball screw, body; Body is the cube that has two intersection through holes; Body also have one with two intersect the groove that through hole connects; Vee-block is connected with ball screw on being screwed in fixed block through fixed head, puts into two grooves that intersect through hole one sides together, with screw fixed block is fastened in the groove; Screw is put into the groove of two intersection through hole opposite sides; Be fastened on body top to pressing plate with screw; Workpiece for measurement is put into and is intersected through hole, between and vee-block and screw between.But turning ball screw can promote vee-block and advance or retreat and screw just clamping work pieces together.Pressing plate plays restriction vee-block upper-lower position and uses.
The beneficial effect of the utility model is: solved Brinell tester small sample impression problems of measurement, enlarged Instrumentation Operating Areas.
Description of drawings:
Fig. 1 is the side view of Brinell tester small sample pressure measurement trace platform.
Fig. 2 is the front elevation of Brinell tester small sample pressure measurement trace platform.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done detailed description.
Fig. 1 is a Brinell tester small sample pressure measurement trace platform.
The body 7 of surveying the trace platform is the cubes that have two intersection through holes.Vee-block 3 is connected with ball screw 6 on being screwed in fixed block 5 through fixed head 4, puts into the groove of body 7 together, with screw fixed block 5 is fastened in the body groove, is fastened on pressing plate 2 usefulness screws on the body.Turn ball screw 6 like this, but it will promote that vee-block 3 moves radially and screw 1 just clamping work pieces 8 together.
Vee-block mechanism assembly sequency:
Ball screw 6 is screwed in the fixed block 5, and ball head is put into the ball-and-socket of vee-block 3, snaps in fixed head 4 thin neck place between screw bulb and screw rod, couples together vee-block 3 and fixed head 4 with screw.Be screwed fixed block 5 in the groove of body 7 again.Like this, turning ball screw 6 can promote vee-block 3 and advance or retreat.2 restrictions of pressing plate vee-block, 3 upper-lower positions are used.
The method of application of the utility model is following:
1. the test desk overturning is placed on the platform; 2. workpiece pressuring mark faces down and puts into vee-block 3, and at this moment, impression plane and test desk plane are in the same plane; 3. screw screw 1 and ball screw 6; 4. dig test desk, at this moment the impression plane can be placed on reading microscope on the tested impression plane size of clearly reading impression diameter up.
The utility model design key points is: when measuring diameter less than the workpiece pressuring mark of 30mm, with vee-block 3 centering, turn that ball screw 6 promotes vee-blocks 3 and screw 1 adds clamping of workpieces 8 together.The impression that makes workpiece 8 is with to survey on the trace platform plane in the same plane, and the reading microscope bottom surface just can surely be put on the survey trace platform on the plane, can carry out reading less than the workpiece pressuring mark of 30mm to diameter.
