Abstract
The utility model relates to a clamp for a microscopic vickers hardness tester to detect hardness of a pencil lead, comprising a clamp body. The clamp body comprises a plurality of clamping jaws for holding the pencil lead and a locking nut for driving the clamping jaws to loosen or clamp. A longitudinal axis is fixedly arranged at the bottom end of the clamp body and inserted in a sleeve barrel at intervals; the side wall of the sleeve barrel is provided with a radial threaded hole; an adjustment bolt which can compress the longitudinal axis is arranged by being matched with the radial threaded hole; the bottom end of the sleeve barrel is fixedly arranged on a base; U-shaped mouths with forward openings or backward openings are respectively arranged at the left side and the right side of the base; and the U-shaped mouths are matched with locking bolts of a sample piece fixing station of the microscopic vickers hardness tester. The clamp has can hold firmly, and is simple in structure, convenient to operate and adjust, is easy to improve detection work efficiency and manufacture.
Description
Technical field
The utility model relates to a kind of anchor clamps, specifically is that the micro-vickers hardness instrument detects pencil-lead hardness anchor clamps.
Background technology
Pencil-lead hardness detects to Vickers hardness detects, but present micro-vickers hardness instrument is not used in the anchor clamps that detect pencil-lead hardness.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of micro-vickers hardness instrument to detect pencil-lead hardness anchor clamps, and its clamping is firm, operation and easy to adjust.
For addressing the above problem, the utility model is by the following technical solutions: this micro-vickers hardness instrument detects pencil-lead hardness anchor clamps, comprise jig main body, described jig main body comprises a plurality of claws that are used for the lead gripper pen core, the set nut that the driving claw unclamps/clamps; The bottom of jig main body sets firmly a longitudinal axis, and this longitudinal axis gap is plugged in the sleeve, and a radial screw bore is set on the sidewall of sleeve, is equipped with an adjustment bolt that can compress longitudinal axis with this radial screw bore; The bottom of described sleeve is installed on the base; The left and right sides of base is provided with opening U-shaped mouth forward or backward respectively, and the lock(ing) bolt on the exemplar fixed station of described U-shaped mouth and micro-vickers hardness instrument cooperates.
The beneficial effects of the utility model are: its clamping is firm, operation and easy to adjust, is convenient to improve testing efficient, and simple in structure, makes easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the front view of the utility model embodiment,
Fig. 2 is the A-A view of Fig. 1,
Fig. 3 is installed in user mode synoptic diagram on the micro-vickers hardness instrument for the utility model embodiment;
Among the figure: 1 jig main body, 11 claws, 12 set nuts, 13 longitudinal axiss, 2 sleeves, 3 adjust bolt, 4 bases, 5U shape mouth, 6 exemplar fixed stations, 7 lock(ing) bolts.
Embodiment
As shown in Figure 1, 2, this micro-vickers hardness instrument detects pencil-lead hardness and comprises jig main body 1 with anchor clamps, and described jig main body 1 comprises a plurality of claws 11 that are used for the lead gripper pen core, the set nut 12 that driving claw 11 unclamps/clamps; The bottom of jig main body sets firmly a longitudinal axis 13, and these longitudinal axis 13 gaps are plugged in the sleeve 2, and a radial screw bore is set on the sidewall of sleeve 2, is equipped with an adjustment bolt 3 that can compress longitudinal axis with this radial screw bore; The bottom of described sleeve 2 is installed on the base 4; The left and right sides of base 4 is provided with opening U-shaped mouth 5 forward or backward respectively.
The micro-vickers hardness instrument is existing known instruments, and it is provided with exemplar fixed station 6, and described exemplar fixed station 6 is provided with lock(ing) bolt 7.U-shaped mouth 5 on the base 4 cooperates with lock(ing) bolt 7 on the exemplar fixed station of micro-vickers hardness instrument.
During use, base 4 is placed on the exemplar fixed station 6 of micro-vickers hardness instrument, utilize its U-shaped mouth 5 to get final product with the firm banking 4 that cooperates of lock(ing) bolt 7.
Before the detection, earlier pencil-lead being formed detection faces by a direction friction on the sand paper of certain roughness, is the cut of formation rule on this detection faces.Then pencil-lead is clamped in the jig main body 1, adjusts set nut 12 and make claw 11 clamp pencil-lead.
During detection, need to adjust the direction of pencil-lead cut, detect requirement, only need unclamp this moment and adjust bolt 3 even pencil-lead rotates to satisfy Vickers hardness, the fine setting of jig main body 1 unitary rotation is got final product, do not need to adjust set nut 12 and make claw 11 unclamp the rotation pencil core.If direct rotation pencil core, rotation amplitude is not easy to grasp, and turns over easily, and turns after having adjusted when set nut 12 makes claw 11 clamping pencil-leads again and cause pencil-lead to rock easily, and pencil-lead does not still reach ideal orientation thereby cause adjusting afterwards.Adjust bolt 3 by unclamping, adjust jig main body 1 unitary rotation and then can avoid the problems referred to above, be easy to be fine-tuning to ideal position, thereby also help increasing work efficiency.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; this area person skilled all should fall in the determined protection domain of the utility model claims various distortion of the present utility model and improvement.
All the other do not state the known technology that technology is the present technique field.
