Abstract
The utility model discloses a shear pin type hammering Brinell hardness tester stand which is characterized by comprising left and right cuboid stand supports separated at a certain distance, wherein connecting screws are arranged on the lower parts of the stand supports and are connected with supporting legs which have the supporting effect, a cuboid shear pin frame support is arranged between the two stand supports, a circular hole is formed in the middle part of the cuboid shear pin frame support, and the stand supports and the shear pin frame support are connected together by means of two parallel connecting rods and can slide on the connecting rods. The cuboid shear pin frame support and the stand supports can be adjusted in a sliding way on the connecting rods, and the height of the supporting legs can be further adjusted, so that the stand can be suitable for various samples and is very convenient to operate, and the success rate of tests is improved.
Description
Technical field
The utility model relates to a kind of shear pin type hammering Brinell tester testing table.
Background technology
Shear pin type hammering Brinell tester as shown in Figure 1, by cutting off frame (gauge head), cut off, pressure head, sleeve, support handle, block of hardness, reading microscope etc. form.During test, cut off with pressure head and be arranged on and cut off on frame, cut off frame and put into sleeve, sleeve is put into support handle, is then placed on sample.With hand hammer, knock and cut off top of the trellis, test force is delivered on pressure head by cutting off, the spherical end surface of pressure head can leave impression on sample, when percussion power reaches the specified shear strength 1580kg cutting off, cut off and can be cut off the cutting system that frame and pressure head form and cut off, pressure head is retracted into and cuts off in frame, test force pop-off, and the test force being subject on pressure head is just in time 1580kg.Reading microscope is read impression diameter, tables look-up, and just obtains the ball hardness number of sample.
The key whether testing successfully is to knock and cut off after top of the trellis with hand hammer, cut off and whether can disposablely cut off, if hammer force is inadequate, cut off and do not cut off, illustrate that hammer force does not reach specified shear strength 1580kg, cause invalidate the test, that after hammering, is not cut off cuts off due to distortion, can not guarantee that specified shear strength is still 1580kg, test is just failed.
Disposable hammering is cut off and is cut off, and needs two conditions: 1) hand hammer precisely hits and cuts off top of the trellis; 2) pressure head is steadily placed on specimen surface.In actual use, only depend on and help handle fixedly to cut off frame at specimen surface, during operation, must take on the other hand and help handle, adept hammer, not easy to operate on the other hand, often causes hammering strength less, cuts off and do not cut off; Also may place shakiness by pressure head, after hammering, leave test position.For the disposable hammering of energy, cut off and cut off, hammer need to leave and cut off frame more a little further, owing to taking and helping handle with hand, while worrying hammering, accidentally injure, dare not make psychologically hammering with all strength, may cause like this miss or impact partially, all will the probability of test failure be increased.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to operate, shear pin type hammering Brinell tester testing table that can adapt to various samples.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of shear pin type hammering Brinell tester testing table, its gordian technique is: it comprises the left side keeping at a certain distance away, the testing table of right two rectangular builds supports, described testing table supports bottom and is provided with connecting screw rod, described connecting screw rod is connected with passive lower margin, the frame that cuts off that is provided with rectangular build between two testing tables support supports, the described frame support middle part that cuts off is provided with circular hole, described testing table supports and cuts off frame support and links together by two parallel connecting links, and it can slide on connecting link.
Adopt the beneficial effect that technique scheme produces to be: of the present utility modelly cut off that frame supports, testing table support can be on connecting link slidable adjustment, and the height of lower margin also can regulate, can adapt to multiple sample like this, and operation is very easy, improved the success ratio of test.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to accompanying drawing 2～accompanying drawing 6, the utility model supports 1 by cutting off frame, and testing table supports 2, connecting link 3, and lower margin 4 four parts form, and wherein connecting link 3 and lower margin 4 can design many group length.Testing table supports 2 and arranges two, between between two testing tables supports 2, be separated with distance, two testing tables are provided with between supporting 2 and cut off frame support 1, the described frame that cuts off supports 1 and is provided with circular hole, cut off frame support 1 and testing table support 2 and be provided with via hole, two connecting links 3 are through this via hole, then mounting nuts, to cut off frame support 1 with testing table support 2 be located by connecting together with, and cut off frame support 1 and testing table support 2 and can on connecting link 3, slide.Described testing table supports 2 belows and is provided with connecting screw rod 5 and lower margin 4, and described connecting screw rod 5 and lower margin 4 are threaded.
During installation, with connecting link 3,2 testing tables are supported to 2 and cut off frame and support 1 and be connected, with nut, connecting link 3 two ends are fixed, testing table support 2 and cut off frame support 1 can slip arbitrarily on connecting link 3, to adapt to various samples.Connecting link 3 can become different lengths standby according to sample design.
4 lower margins 4 are arranged on 4 connecting screw rods 5 of testing table support 2, on lower margin 4, offer internal thread, it is external thread that testing table supports 2 connecting screw rod, like this with regard to the height of adjustable testing table, it is standby that lower margin 4 can design multiple height as required, increases the usability of testing table.
During use, this testing table is placed on to specimen surface, as circular bolt shank, by cutting off frame, through cutting off frame, supports the circular hole in the middle of 1, adjusting cuts off frame and supports 1 in connecting link 3 slips, make to cut off frame lower end and aim at accurately the position that needs test, regulate 4 lower margins 4, make to cut off just adjacent specimen surface of frame lower end, testing table is held and is cut off frame, with hand hammer, precisely hit and cut off top of the trellis, eliminate and accidentally injure psychology, guarantee to cut off disposable cutting off.
The utility model can adapt to various samples, will cut off frame and be placed in testing table, replaces and helps handle, and while guaranteeing hammering, disposable hammering is cut off and cut off.
