Abstract
A hardness test sample block fixing device relates to the filed of holding devices, and includes a fixing body, guide rods, clamping blocks and springs, wherein the fixing body adopts a square ring structure with one opened side; at least two through holes are arranged in the middle lateral wall on the open side in the structure; the guide rods are slidingly mounted in the through holes in a sleeving manner; a handle is fixedly connected with the end of each guide rod, positioned outside the fixing body; one clamping block is fixedly connected with the end of each guide rod, positioned inside the fixing body; the rod bodies of the guide rods positioned inside the fixing body are sleeved with the springs; and one clamping block is correspondingly in contact with the inner surface of the lateral wall on the opposite side of the opening of the fixing body in a fitting manner. The device can be used for effectively positioning and clamping sample blocks with smaller volumes and irregular shapes in the hardness test, so as to quickly and accurately read the diameter value of indentation of the sample block.
Description
[technical field]
The utility model relates to the clamping device field, especially relates to a kind of for the stationary installation at hardness test clamping test sample piece.
[background technology]
Known, hardness detects test and need to utilize reading microscope to measure the impression diameter of test sample piece, then by tabling look-up or calculating the hardness number of sample, yet, in practical operation, because the detection frequency of hardness test is higher, small volume and the pole of figure of test sample piece are irregular, therefore, when the impression plane width of sample piece during less than the lens barrel diameter of reading microscope, the Parallel testing on sample piece impression plane and lens barrel plane requires often to arrive scarcely ever and satisfies, this has not only caused sample piece impression plane and the lens barrel plane can not be corresponding parallel fast and accurately, but also can cause hardness test to have influence on the accuracy of detection because of the reading difficulty, and finally have influence on the whole efficiency of hardness test.
[summary of the invention]
In order to overcome the deficiency in the background technology, the utility model provides a kind of hardness test sample piece stationary installation, described device can be in hardness test effectively to small volume and sample piece in irregular shape position, clamping, thereby reach the purpose that reads fast and accurately sample piece impression diameter numerical value.
For achieving the above object, the utility model adopts following technical scheme:
A kind of hardness test sample piece stationary installation, described device comprises fixed body, guide rod, grip block and spring; Described fixed body is the uncovered square ring structure of a side, and the sidewall of uncovered side middle part is provided with at least two through holes in this structure; In the described through hole all slip cap guide rod is housed, the termination that guide rod is positioned at the fixed body outside is fixedly connected with same handle, the termination that guide rod is positioned at fixed body inside is fixedly connected with same grip block, and the guide rod shaft that is positioned at fixed body inside is set with spring; Described grip block and the identical corresponding contact of the inner face of the uncovered opposite side sidewall of fixed body.
Described hardness test sample piece stationary installation, the described grip block end face corresponding with the uncovered opposite side sidewall of fixed body is installed with respectively rubber sheet gasket.
Described hardness test sample piece stationary installation, described guide rod and handle and grip block are silk and connect.
Owing to having adopted technique scheme, having the utlity model has following beneficial effect:
Hardness test sample piece stationary installation described in the utility model can be in hardness test effectively to small volume and sample piece in irregular shape position, clamping, thereby make the impression plane of sample piece and the plane of lens barrel can be corresponding parallel fast and accurately, this has not only reached the purpose of utilizing reading microscope to read fast and accurately the sample piece impression diameter numerical value in the test, but also effective guarantee the whole efficiency of hardness test.

Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is that the A of Fig. 1 is to schematic diagram;
Fig. 3 is the use view of Fig. 2.
Among the figure: 1, fixed body; 2, through hole; 3, guide rod; 4, handle; 5, grip block; 6, spring; 7, rubber sheet gasket; 8, sample piece; 9, impression.
[embodiment]
Can explain in more detail the utility model by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;
1～2 described hardness test sample piece stationary installation by reference to the accompanying drawings, described device comprises fixed body 1, guide rod 3, grip block 5 and spring 6; Described fixed body 1 is the uncovered square ring structure of a side, the sidewall of uncovered side middle part is provided with at least two through holes 2 of suit guide rod 3 that slide in this structure, thereby has ensured that guide rod 3 can also have preferably stationarity carrying out the pull action along these through holes 2 when; The fixing silk in an end termination that described guide rod 3 is positioned at fixed body 1 outside connects same handle 4, thereby reaches the purpose of utilizing this handle 4 to make all guide rods 3 synchronization actions; The fixing silk in an end termination that guide rod 3 is positioned at fixed body 1 inside connects same grip block 5, and namely the guide rod 3 by synchronization action drives grip block 5 and carries out stably corresponding displacement; In addition, guide rod 3 shafts that are positioned at fixed body 1 inside are set with spring 6, namely utilize the elastic force of these springs 6 to guarantee that grip block 5 can set back after movement, thereby jointly come the firm sample piece 8 that needs test that clamps by the uncovered opposite side sidewall of grip block 5 and fixed body 1; Firm degree when being held for further strengthening sample piece 8, can fixedly mount respectively rubber sheet gasket 7 by the end face that grip block 5 is corresponding with the uncovered opposite side sidewall of fixed body 1, thereby utilize friction between rubber sheet gasket 7 and the sample piece 8 to strengthen the firmness of clamping.
By reference to the accompanying drawings 3, when implementing hardness test sample piece stationary installation described in the utility model, first described device is kept flat on the table, outwards twitching handle 4 makes guide rod 3 drive grip block 5 holddown springs 6 again, keep motionless when being positioned at suitable position for to be held 5, then place the test sample piece 8 that needs detection in the position of after grip block 5 moves, vacating, and the impression 9 of sample piece 8 faced down keep flat on the table, again slowly unclamp handle, utilize the elastic force of spring 6 that grip block 5 is set back, thus with sample piece 8 tightly be fixed on fixed body 1 inside; After fixing sample piece 8,, the impression 9 of sample piece 8 is faced up with described device the other way around, and impression 9 is aimed in the optical center of reading microscope, then namely can operate reading microscope the sample piece has been detected; At this moment, because 9 of the impressions of sample piece 8 are concordant towards the one side of top with described device, thereby the lens barrel plane with reading microscope that just can simple and fast is placed on corresponding parallel position with impression 9 faces of sample piece 8, thereby not only satisfied the requirement that needs sample piece impression plane and lens barrel plane in the test are in parastate, also effective guarantee the reading of hardness test precisely reach the efficient of detection.
Carefully do not state part in the above content for prior art, do not state therefore run business into particular one.
