Embodiment 1

[0012] Embodiment 1 A new type of clamp for a universal tensile machine according to the present invention includes three parts: an iron clip, an alloy force transmission bracket, and an alloy chuck. The three parts are fixed by electric welding. For specific dimensions, see Figure 1-Figure 3 .

[0013] The clip is an iron sheet with a length of 23.2mm, a width of 14.0mm, and a thickness of 6.2mm, which is fixed by the chuck of the universal tensile machine;

[0014] The alloy force transmission bracket is a cylindrical alloy bracket with a length of 50.0mm and a diameter of 4.0mm, which is used to conduct the tension between the iron clip and the alloy chuck;

[0015] The alloy collet includes a fixed collet and a movable collet, and the fixed collet and the movable collet are connected by a hexagon socket bolt with a diameter of 9.0 mm. A spring is convenient for the use of the fixture; the jaws are serrated to increase the clamping force of the jaws and improve the stabil...

Abstract

The invention discloses a novel all-purpose tensile machine clamp. The novel all-purpose tensile machine clamp is successfully applied to an LED (Light Emitting Diode) bracket tensile test, aiming atthe characteristics of a current LED bracket that the stretching distance is short, stressed area of a bracket leg is small and the like and improving according to actual conditions of an all-purposetensile machine in a utilization process. The novel all-purpose tensile machine clamp disclosed by the invention is simple in structure and easy to use; the testing time is reduced and the reliabilityof testing data is enhanced.

Description

technical field [0001] The invention relates to a novel fixture of a universal tensile machine, which can be used in conjunction with the universal tensile machine to measure the tensile strength of LED lamp beads. technical background [0002] Universal tensile machine is a kind of equipment used to test the tensile strength of rubber, plastic, fiber, metal wire and other materials. Different design fixtures can test the tensile strength of more special-shaped materials. Usually the distance between the metal bracket pins of the LED is only 15mm, and the area of ​​each bracket pin is only 3-9mm 2 , the existing universal tensile machine fixture cannot clamp the bracket pins. The invention can clamp a sample with a small force bearing area, such as the pins of an LED bracket, and smoothly perform a tensile strength test. Contents of the invention [0003] The object of the present invention is to provide a new clamp for a universal tensile machine, which is characterized...
