Abstract
The utility model discloses a clamp block with a compression plane used for a vibrating wire strain gauge. The clamp block comprises a clamp block body (2) with a positioning surface (1); a clamp gap (3) and a central sink hole (4) are formed on the clamp block body (2); and a compression plane (6) is arranged on the clamp block body (2). Since the compression plane is arranged on the clamp block body, the top wire applies a force in the direction perpendicular to the compression plane, so as to prevent bending. Besides, a circular slot is formed at the bottom of the clamp gap, so as to eliminate the processing stress of the bottom of the clamp gap, solve the problem in the prior art that the bottom of the clamp gap is liable to crack, ensure stable clamping force and improve the measurement accuracy. The clamp block provided by the utility model is easy and feasible, is convenient to process and has a remarkable effect.
Description
Technical field
The utility model relates to the part of using on a kind of strainometer, particularly relates to the fixture block with clamping plane that a kind of vibrating string extensometer is used.
Background technology
Fixture block is the parts that are used for clamping string silk on the vibrating string extensometer, fixture block is provided with crack, symmetry is provided with two fixture blocks in vibrating string extensometer, the two ends of string silk by the crack clamping on two fixture blocks respectively, and be tightened up, the string silk between two fixture blocks can induce the slight vibration of measured object.Fixture block is to exert pressure in the vertical direction of crack by jackscrew when clamping the string silk, crack is produced narrow down, and the string silk is clamped.
At present when clamping, jackscrew is directly to withstand on the arc surface of fixture block, and the end of jackscrew easily produces sideslip, because the jackscrew that is used to hold out against is very thin, easily makes the jackscrew end bent.Cause the holding force instability, influence measuring accuracy.
The utility model content
The purpose of this utility model is, the fixture block that provides a kind of vibrating string extensometer to use with clamping plane, because fixture block is provided with clamping plane, jackscrew is perpendicular to the clamping plane application of force, and is not flexible, can keep stable holding force, improves measuring accuracy.
The technical solution of the utility model: the fixture block that a kind of vibrating string extensometer is used with clamping plane, comprise the fixture block body that is provided with locating surface, the fixture block body is provided with crack and center counterbore, is provided with clamping plane on the fixture block body.
In the fixture block with clamping plane that aforementioned vibrating string extensometer is used, described clamping plane is parallel with crack.
In the fixture block that aforementioned vibrating string extensometer is used, be provided with circular groove at the bottom of the seam of described crack with clamping plane.
Compared with prior art, the utility model is because fixture block is provided with clamping plane, and jackscrew is perpendicular to the clamping plane application of force, and is not flexible.Be provided with circular groove in the crack bottom in addition, eliminated the machining stress of crack bottom, the crack bottom that has overcome prior art is prone to the problem of crackle, can keep stable holding force, improves measuring accuracy.The utility model is simple, and is easy to process, and effect is remarkable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a schematic appearance of the present utility model;
Fig. 3 is the prior art constructions synoptic diagram.
Being labeled as in the accompanying drawing: 1-locating surface, 2-fixture block body, 3-crack, 4-center counterbore, 5-circular groove, 6-clamping plane.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction foundation of the present utility model.
Embodiment.The utility model as shown in Figure 1.Fig. 1 of the present utility model 1/4 analyses and observe schematic perspective view, as seen from Figure 1, the fixture block with clamping plane that a kind of vibrating string extensometer is used comprises the fixture block body 2 that is provided with locating surface 1, fixture block body 2 is provided with crack 3 and center counterbore 4, is provided with clamping plane 6 on fixture block body 2.Clamping plane 6 is parallel with crack 3.Be provided with circular groove 5 at the bottom of the seam of crack 3.
During concrete enforcement, can use lathe car system fixture block body 2 earlier, fixture block body 2 is made of the right cylinder of two sections different-diameters, junction at two sections different-diameters forms locating surface 1, end face at large diameter cylinder bores a center counterbore 4, and the degree of depth in hole should surpass the reduced diameter section that locating surface 1 is drilled into fixture block body 2.Mill a clamping plane 6 with milling cutter at the reduced diameter section of fixture block body 2, bore a through hole radially at reduced diameter section near the position of locating surface 1 then, as the crack circular groove 5 at the 3 seam ends, circular groove 5 is parallel with clamping plane 6.Reprocess crack 3 at last, mill out a seam with circular peripheral-mill at the reduced diameter section of fixture block body 2, seam is parallel with circular groove 5 and on same plane, stitches the end and circular groove 5 and mills logical.After heat treatment get finished product at last.The finished product outward appearance is shown in Fig. 2.
Fig. 3 is the prior art constructions synoptic diagram, as can be seen from Figure 3, does not have clamping plane 6 on the existing fixture block body 2, jackscrew is directly to withstand on the arc surface of fixture block, the end of jackscrew easily produces sideslip, because the jackscrew that is used to hold out against is very thin, easily makes the jackscrew end bent.Crack of the prior art 3 bottoms are that circular groove 5 is not established at the right angle, from cracking from the right angle easily, cause the holding force instability, influence measuring accuracy.
Claims (3)
1. the fixture block with clamping plane that vibrating string extensometer is used comprises the fixture block body (2) that is provided with locating surface (1), and fixture block body (2) is provided with crack (3) and center counterbore (4), it is characterized in that: be provided with clamping plane (6) on fixture block body (2).
2. the fixture block of using according to the described vibrating string extensometer of claim 1 with clamping plane, it is characterized in that: described clamping plane (6) is parallel with crack (3).
