Abstract
The utility model relates to a clamp for testing Rockwell hardness of a clamping piece. The clamp consists of a base, a supporting block and a stopper, wherein the base is in an L shape and is provided with wedge grooves on the upper surface of a horizontal plane in equal distance at intervals; the bottom surface of the stopper is provided with a wedge block which protrudes downwards and corresponds to the wedge grooves; the stopper is arranged on the horizontal plane of the base; the wedge block is inserted into the wedge grooves; and the supporting block is overlapped between the stopper and the base. By adoption of the technical scheme, the clamp is easy and convenient to operate, and the inclination angle of the sample to be tested can be rapidly adjusted, so that a to-be-tested surface of the sample is perpendicular to an axis of a pressing head, and an experimental error is reduced.
Description
Technical field
The utility model relates to a kind of intermediate plate Rockwell hardness test fixture of testing profiled bar.
Background technology
Often need to carry out hardness test to irregular profiled bar in highway engineering; and be difficult in process of the test due to profiled bar guarantee that its surface to be measured keeps vertical with the ram axis of test unit; therefore often error can occur in experiment, affect construction quality.
Summary of the invention
The purpose of this utility model is to propose a kind of easy and simple to handle, can locate fast, makes the being tested surface intermediate plate Rockwell hardness test fixture vertical with the ram axis maintenance of sample.
The purpose of this utility model is achieved in that intermediate plate Rockwell hardness test fixture is comprised of base, back-up block and block.Base is L shaped, offers the wedge groove in the upper surface equi-spaced apart of its surface level.Place, block bottom surface is provided with outstanding downwards, the voussoir corresponding with the wedge groove.Stopper seat is on the base surface level, and voussoir inserts in the wedge groove, is overlapped with back-up block between block and base.
Owing to implementing technique scheme, the utility model is easy and simple to handle, but the angle of inclination of quick adjustment testing sample, thus make the being tested surface of sample keep vertical with ram axis, reduce experimental error.
Description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is intermediate plate Rockwell hardness test clamp structure schematic diagram.
Legend: 1. base, 2. back-up block, 3. intermediate plate to be measured, 4. block, 5. wedge groove.
Embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment
:As shown in Figure 1, intermediate plate Rockwell hardness test fixture is comprised of base 1, back-up block 2 and block 4.Base 1 is L shaped, offers wedge groove 5 in the upper surface equi-spaced apart of its surface level.Block 4 places, bottom surface are provided with outstanding downwards, the voussoir corresponding with wedge groove 5.4 of blocks are on base 1 surface level, and voussoir inserts in wedge groove 5, is overlapped with back-up block 2 at block 4 and 1 of base.Block 4 and base 1 opposite face lower end angle is outstanding outward, and the interior angle of teat is arc chord angle.Back-up block 2 two ends are round end.
In when experiment, intermediate plate 3 to be measured is placed on back-up block 2, by regulating the diverse location of block 4 on base 1, thereby regulate the angle of back-up block 2 and surface level, and then it is vertical with ram axis to regulate the test surfaces of fixture block 3 to be measured.
Above technical characterictic has consisted of most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, satisfies the needs of different situations.
