Abstract
The invention relates to a ball pressure heat resistance tester. The ball pressure heat resistance tester includes a load body and a support plate, the support plate is placed on a bottom plate through a stand column, the lower end of the load body is an inverted-cone body, the lower end of the inverted-cone body is provided with a steel ball with the radius R of 2.5 mm, a test sample is placed in the center of the upper end surface of the support plate, the steel ball presses over the test sample, a through hole is formed in the load body in the radial direction, a connection rod is installed in the through hole, the two ends of the connection rod are sleeved with weights respectively, the weights can move on the connection rod, the two ends of the connection rod are connected with adjusting nuts through screw threads, and the adjusting nuts are located outside the weights. The ball pressure heat resistance tester is simple in structure and convenient to operate, and the adjusting nuts are arranged at the two ends of the connection rod for adjusting the weights at the two ends of the connection rod so as to ensure the balance of the two ends of the connection rod.
Description
Technical field
A kind of the present invention relates to test instrument, more particularly to bulb pressure heat resistant test instrument.
Background technology
Ball indentation test is one of a kind of method of measure plastic hardness and heat resistance of nonmetal material of International Organization for standardization's recommendation in electrical safety field, in test, the condition specified by standard, with certain etc ball indentation test device in certain temperature, regular hour is pushed down into the surface of nonmetallic, non-ceramic material to check the test of electric tool structure material thermal resistance, to ensure that sample, under high temperature operating conditions, has enough support strengths, do not cause electrical safety hidden danger.Existing ball pressure heat resistant test apparatus structure is more complicated, and inconvenient operation, manufacturing cost are high.
The content of the invention
For drawbacks described above, it is an object of the invention to provide a kind of simple structure, easy to operate, the bulb pressure heat resistant test instrument of low cost of manufacture.
For this technical solution adopted in the present invention it is：
Including load body and gripper shoe, the gripper shoe is placed on by column, the load body lower end is vertebral body, the lower surface of the vertebral body is sphere, the spherical radius is R2.5mm, the upper surface of the gripper shoe is placed with sample, the lower end sphere of the vertebral body is pressed on sample, the load body is radially provided with through hole, connecting rod is installed in the through hole, the two ends of the connecting rod are cased with counterweight respectively, the counterweight can be moved in connecting rod, the two ends of the connecting rod have been threaded connection adjusting nut, the adjusting nut is located at the outside of counterweight.
Further, the bending two ends of the connecting rod are downwards and with connecting rod Central Symmetry.
Further, the load body upper end is provided with tapped through hole and is communicated with through hole, is provided with lock-screw for locking connecting rod in the tapped through hole.
It is an advantage of the invention that：
Present configuration is simple, easy to operate, by arranging adjusting nut at connecting rod two ends, for adjusting the counterweight at connecting rod two ends, it is ensured that connecting rod two ends balance, and by setting up lock-screw in load body upper end, are further conveniently adjusted the degree of balance of connecting rod.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
1 it is load body in figure, 2 be gripper shoe, 3 be column, 4 be base plate, 5 be sample, 6 be connecting rod, 7 be counterweight, 8 be adjusting nut, 9 is lock-screw.
Specific embodiment
One bulb presses heat resistant test instrument, including load body 1 and gripper shoe 2, the gripper shoe 2 is placed on base plate 4 by column 3, 1 lower end of load body is vertebral body, the lower surface of the vertebral body is sphere, the spherical radius is R2.5mm, the upper surface of the gripper shoe 2 is placed with sample 5, the lower end sphere of the vertebral body is pressed on sample 5, the load body 1 is radially provided with through hole, connecting rod 6 is installed in the through hole, the two ends of the connecting rod 6 are cased with counterweight 7 respectively, the counterweight 7 can be moved in connecting rod 6, the two ends of the connecting rod 6 have been threaded connection adjusting nut 8, the adjusting nut 8 is located at the outside of counterweight 7；The bending two ends of the connecting rod 6 are downwards and with 6 Central Symmetry of connecting rod；1 upper end of load body is provided with tapped through hole and is communicated with through hole, is provided with lock-screw 9 for locking connecting rod 6 in the tapped through hole.
