Abstract
The invention relates to a tensile test clamping device for a universal testing machine. The tensile test clamping device comprises a left pressing board, a right pressing board, a base plate and a fixture seat, the base plate and the fixture seat are sequentially placed in a beam jaw, and the left pressing board and the right pressing board are snapped on two sides of the base plate respectively and fixed on a beam by bolts. Protruding portions are milled at two ends of the base plate, a groove is respectively milled in the middles of the left pressing board and the right pressing board, and the grooves are matched with the protruding portions at two ends of the base plate in sizes. The tensile test clamping device is compact and reasonable in structure; the base plate and the fixture seat are installed in the beam jaw and used for tensile tests of metal materials or non-metal materials; and during using, the base plate is fixed in the jaw so that the base plate is difficult to pull out, and the device is simple in processing, durable and convenient to replace.
Description
Technical field
The present invention relates to a kind of clamping device, especially a kind of universal testing machine clamping device for tensile test is installed in the jaw of universal testing machine crossbeam, is used for the tension test of metal material or nonmetallic materials.
Background technology
Before the present invention made, in prior art, the clamping device for the tension test of metal material or nonmetallic materials is adopted was generally backing plate and is screwed on the side of jaw or on the pressing plate,
Increase the wearing quality of jaw side.This kind structure in use because pulling force is larger, screw extraction, backing plate is drawn out, and causes and can't use.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, a kind of universal testing machine clamping device for tensile test is provided, this clamping device is fixed on jaw Inner with pressing plate with backing plate, and backing plate is difficult for being drawn out, and processing is simple, durable, and it is convenient to change.
According to technical scheme provided by the invention, a kind of universal testing machine comprises left pressing plate, right pressing plate, backing plate and clamping fixture seat with clamping device for tensile test; Described backing plate, clamping fixture seat are successively placed on the crossbeam jaw, and left pressing plate, right pressing plate are stuck in the backing plate both sides, with bolt left pressing plate, right pressing plate are fastened on the crossbeam.
As a further improvement on the present invention, the two ends of described backing plate are milled with outshot.
As a further improvement on the present invention, the centre of described left pressing plate and right pressing plate is milled with respectively groove, and the outshot size at described groove and backing plate two ends is complementary.
As a further improvement on the present invention, described chuck is stuck on the clamping fixture seat.
Compared with the prior art the present invention has the following advantages:
Compact conformation of the present invention, reasonable; Be installed in the jaw of universal testing machine crossbeam, be used for the tension test of metal material or nonmetallic materials; Pressing plate is fixed on backing plate in the jaw during use, and backing plate is difficult for being drawn out, and processing is simple, durable, and it is convenient to change.
Description of drawings
Fig. 1 is that B of the present invention is to the TV structure synoptic diagram.
Fig. 2 is that structure of the present invention is used constitutional diagram.
Embodiment
Following the present invention is further described in connection with the embodiment in the accompanying drawing:
