Abstract
The utility model discloses a tensile test clamp for quenching state powder metallurgy parts, which comprises an upper clamp device and a lower clamp device. The structure of the upper clamp device is that a first connection rod is hinged on an upper clamp head through a support pin, a second connection rod is hinged below the first connection rod, and a pin hole is arranged at the clamp end of the second connection rod, a location pin penetrates through the pin hole. The structure of the clamp device is identical with the structure of the upper clamp device, and the upper clamp device and the lower clamp device are symmetrically arranged. When the tensile test clamp is used, a tensile sample with location holes at two ends is prepared, the tensile test clamp is arranged on a universal material test machine, the location pins penetrate through the pin hole of the second connection rod and the location hole of the tensile sample, the tensile sample is clamped, and a tensile test is performed. Due to the fact that the tensile sample is clamped by the location pin, the tensile sample cannot be pulled away in stretching, and the tensile test for quenching state powder metallurgy parts can be performed smoothly.
Description
Technical field
The utility model relates to a kind of tensile test fixture of the attitude metallic sintered products that quenches, and is applied to universal testing machine, can carry out tension test to Q-tempering attitude high rigidity, high-intensity metallic sintered products, to record its mechanical property.
Background technology
Present tensile test fixture; Its chuck is directly clamped two end surfaces of tensile sample, because hardness is high behind the tensile sample Q-tempering, intensity is high, tensile sample can't be clamped fully; Sample is directly deviate from chuck during stretching, can't detect the mechanical property of material therefor.
Summary of the invention
Come off from chuck for fear of tensile sample in the process that stretches, the utility model proposes a kind of tensile test fixture of the attitude metallic sintered products that quenches.
For this reason; The technical scheme of the utility model is: a kind of tensile test fixture of the attitude metallic sintered products that quenches; Comprise clamping device, following clamping device, it is characterized in that: the structure that goes up clamping device is: on upper grip, be hinged with head rod through supporting pin, be hinged with second connecting link under the head rod again; The bare terminal end of second connecting link is provided with pin-and-hole, is installed with register pin in the pin-and-hole; The structure of following clamping device is identical with the structure of last clamping device, and last clamping device is symmetrical set up and down with following clamping device.
Beneficial effect: when using the utility model; Prepare the tensile sample that two ends have pilot hole earlier, be contained in the utility model on the universal testing machine, register pin passes the pin-and-hole of second connecting link, the pilot hole of tensile sample; Grasp tensile sample, carry out tension test then.Because tensile sample can not be deviate from when stretching through the register pin clamping, thus the tension test of the attitude metallic sintered products that quenches smoothly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; It is following to further describe the utility model: a kind of tensile test fixture of the attitude metallic sintered products that quenches, comprise clamping device, following clamping device, and the structure of last clamping device is: upper grip is made up of left chuck 1, right chuck 2; On upper grip, be hinged with head rod 4 through supporting pin 3; Head rod 4 times is provided with pin-and-hole through the bare terminal end that pin 3 is hinged with second connecting link, 5, the second connecting links 5 again, is installed with register pin 6 in the pin-and-hole; The structure of following clamping device is identical with the structure of last clamping device, and last clamping device is symmetrical set up and down with following clamping device.
Left side chuck 1 and right chuck 2 are provided with the register pin 8 with the universal testing machine location.
Register pin 8 passes the pin-and-hole of second connecting link, the pilot hole of tensile sample, and the tensile sample 7 that has two ends pilot hole grasps.
