Description
Technical field:
The utility model is relevant with the hold assembly of Material Testing Machine, and is especially relevant with the anchor clamps of metal, rigid plastic and other compound examination materials.
Background technology:
In the material tensile test field, must reliable clamping sample, it is moving to prevent to skid, and could accurately ask for the technical parameters such as tensile strength, yield strength, extensibility, unrelieved stress, elastic modulus of material.Existing anchor clamps have following shortcoming:
1, conventional brace in order to ensure intensity, has to strengthen the relative dimensions of anchor clamps owing to adopted the open type structure, makes clamp body seem heavy, operation inconvenience.
2, the factor affecting of conventional brace structure heat-treated is very big, and heat treatment hardness directly influences the intensity of anchor clamps.
3, the design feature of conventional brace V-type fixture block self is at the V-arrangement root, quenches easily to crack, and easily produces the stress concentration phenomenon during clamping, and its cracking is an insurmountable problem in design and the manufacture process always.Conventional brace is front and back opening shapes, in case the fixture block cracking flies out, very easily hurts sb.'s feelings.
The content of utility model:
The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture with low cost, intensity height, long service life, handling safety, convenient, fast, the little curve wedge type stretching clamp of operation labour intensity.
The utility model is achieved in that
The utility model arc wedge shape stretching clamp, the thread end of clamp body 9 has through hole and pull bar 1 movingly, clamp body bare terminal end inwall 15 cooperates formation closed inner chamber 14 with the outer wall 16 of V-arrangement fixture block 13, the thread end of clamp body 9 and the screw-internal thread fit of stroke nut, stroke nut and pull bar 1 have axial restraint mechanism, clamp body 9 has radially fixed mechanism with pull bar 1, and the upper end of pull bar 1 is connected with clamping fixture seat, and the lower end is connected with V-type fixture block 13.
The cambered surface that tapering arranged of the outer wall 16 of clamp body openend inwall 15 and fixture block 13 for matching, clamp body openend inwall 15 have guider screw 12 to cooperate with axial slide 17 on fixture block 13 outer walls 16.
Inner chamber 14 sidewalls have cover plate 10 and clamp body 9 to be hinged, and pearl 8 is bumped at both closed places.
Stroke nut is linked by the external thread of the internal thread of top nut 3 and lower nut 6 and constitutes, the internal thread of lower nut 6 connects with the thread end of clamp body 9, the shaft shoulder 18 that the axial restraint mechanism of pull bar 1 matches for the groove with upper and lower nut formation, the radially fixed mechanism of pull bar is the feather key 4 that cooperates with the keyway of clamp body 9, there is handle 5 to be threaded with top nut 3, and locking lower nut 6.
Transmission rod 11 is arranged between pull bar 1 and fixture block 13, the two ends of transmission rod 11 are T shape, are connected with the T-slot of pull bar 1 with fixture block 13 respectively.
The utility model has following advantage:
1, adopt arc surface V-type fixture block, be sliding fit with the arc surface of clamp body, make fixture block be state of siege in clamp body, the clamping component of fixture block directly bears on clamp body, and the V-type fixture block is not easy to crack like this, has improved processing safety;
2, anchor clamps are light and handy, and are easy to loading and unloading, be out of shape little, the accuracy of detection height.The utility model adopts enclosed construction, and the intensity of anchor clamps is increased considerably, thereby reduces distortion effectively.
3, the utility model employing is streamlined adopts the advanced technologies manufacturing in conjunction with the convex-concave design, the modern design uniqueness, and outward appearance is beautiful.Simple in structure, easy to manufacture, with low cost, long service life.

Embodiment:
The utility model curve wedge type stretching clamp ingredient has: pull bar 1, set nut 2, stroke top nut 3, feather key 4, handle 5, stroke lower nut 6, rotating shaft 7, bump pearl 8, clamp body 9, cover plate 10, transmission rod 11, guider screw 12, fixture block 13.The assembly relation of above-mentioned part is as follows:
1. by the circular hole 19 on the pull bar 1, directly be connected on the upper and lower clamping fixture seat with latch.Make anchor clamps and clamping fixture seat locking with set nut 2, anchor clamps are not rocked.
2. feather key 4 is loaded on the pull bar 1, can slide up and down in clamp body 9 keyways, is used to prevent that pull bar 1 from rotating.
3. stroke top nut 3 screws on the stroke lower nuts 6, with handle 5 both is joined as a wholely, and pull bar 1 shaft shoulder of centre can inside rotate.Turn handle 5 can make clamp body parallel motion about in the of 9.
4. 13 of pull bar 1 and fixture blocks pass through transmission rod 11 to sample transmission pretightning force, make sample just be in the clamping stress before test is carried out, and sample is non-slip.
5. fixture block 13 adopts arc surfaces to slide with clamp body 9, makes fixture block 13 in the process of moving up and down automatic deciliter by guiding spiral shell 12.
6. cover plate 10 7 rotating opening around the shaft are so that change fixture block 13.When shutting, bump pearl 8 and block cover plate 10 automatically, easy to use.
Operating process is as follows:
After the off-test, turn handle 5 unclamps fixture block 13, takes off sample.
For different samples, change the fixture block of corresponding specification and test: at first open cover plate 10, behind the taking-up transmission rod 11, upwards slide and taking-up fixture block 13,, load onto transmission rod 11, close upper cover plate 10 along the fixture block 13 that guider screw 12 is packed into and newly changed.
