Abstract
The utility model relates to a special clamp for a tension testing machine. The special clamp for the tension testing machine comprises a front clamping block, a clamp positioning block, a rear clamping block and a clamp handle, wherein positioning holes are formed in the clamp positioning block; the front clamping block, the clamp positioning block and the rear clamping block are fixedly mounted through a lock bolt passing through the positioning holes; the clamp handle is mounted on the lower part of the clamp positioning block through a pin; and a pressure spring is sleeved on the lock bolt between the front clamping block and the rear clamping block. The special clamp for the tension testing machine is simple in structure and scientific and reasonable in design, is suitable for tension test of workpieces with multiple welding studs or rivets, and is convenient to use and operate.
Description
Technical field
The utility model belongs to unit clamp field, especially a kind of tension tester unit clamp.
Background technology
The unit clamp that is used for test test specimen pulling force in tension tester is more single, is only suitable for the tensile test of a certain specific products.As for products such as bow-tie, epaulet, shoulder badge, buttons, in doing tensile test, often do a kind and all will again change one time fixture, so not only the operator relatively requires great effort from operating aspect, also need to readjust the position of puller system, be not suitable for the workpiece that many weldering nails or rivet etc. connect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of tension tester unit clamp is provided, and this unit clamp is simple in structure, design science reasonable, be adapted to the tensile tests that weld nail or rivet workpiece more, uses easy and simple to handle.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of tension tester unit clamp, its unit clamp comprises front clamp piece, clamping position piece, rear grip block and clamp holder, be shaped with pilot hole on the clamping position piece, front clamp piece, clamping position piece and rear grip block are fixedly mounted with by the clamping screw that passes pilot hole, clamp holder is arranged on clamping position piece bottom by pin, is set with stage clip on the clamping screw between front clamp piece and rear grip block.
And, be shaped with respectively engaging tooth on the surface of contact of described clamping position piece and front clamp piece and clamping position piece and rear grip block.
And, being fixed with guide pole on described clamping position piece, the front clamp piece is spacing by guide pole.
Advantage of the present utility model and beneficial effect are:
This tension tester unit clamp comprises front clamp piece, clamping position piece, rear grip block and clamp holder, be shaped with pilot hole on the clamping position piece, front clamp piece, clamping position piece and rear grip block are fixedly mounted with by the clamping screw that passes pilot hole, clamp holder is arranged on clamping position piece bottom by pin, be set with stage clip on clamping screw between front clamp piece and rear grip block, this is simple in structure, design science is reasonable, be adapted to the tensile tests that weld nail or rivet workpiece more, uses easy and simple to handle.

Fig. 2 is the rear view of Fig. 1;
Fig. 3 is that the utility model uses constitutional diagram (broken section).
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of tension tester unit clamp, its unit clamp comprises front clamp piece 2, clamping position piece 6, rear grip block 8 and clamp holder 7, be shaped with pilot hole 13 on the clamping position piece, front clamp piece, clamping position piece and rear grip block are fixedly mounted with by the clamping screw 3 that passes pilot hole, clamp holder is arranged on clamping position piece bottom by pin 5, be set with stage clip 12 on clamping screw between front clamp piece and rear grip block, be shaped with respectively engaging tooth 1 on the surface of contact of clamping position piece and front clamp piece and clamping position piece and rear grip block.Be fixed with guide pole 4 on the clamping position piece, the front clamp piece is spacing by guide pole.
The utility model is placed on tension tester in use, clamp holder is arranged on the lower gripper 14 of tension tester, the supporting leg 11 of test specimen 10 is clamped in respectively between front clamp piece, clamping position piece, rear grip block, upper clamper 9 clamping test pieces of tension tester are regulated the height of lower gripper to be fit to tensile test.Then test specimen to be tested is fixed on this fixture, the adjusting of fixture is by clamping screw and coordinates stage clip to realize the size of chucking opening, opens at last the tensile test electromechanical source, makes its easy motion, until till completing tensile test.
