Bearing steel ball strength test experiment table capable of automatically rotating test surface

Abstract

The invention discloses a bearing steel ball strength test experiment table capable of automatically rotating a test surface. The bearing steel ball strength test experiment table comprises a base, the base is fixedly connected with an L-shaped plate, the bottom of the L-shaped plate is fixedly connected with an air hammer, the output end of the air hammer is fixedly connected with a strength test block, the base is provided with a sliding groove, a sliding plate is slidably connected into the sliding groove, a reciprocating lead screw is rotatably connected to the inner wall of the sliding groove, the reciprocating lead screw penetrates through the sliding plate and is connected with the sliding plate in a matched mode, a rotating rod is fixedly connected to the other end of the reciprocating lead screw, and the rotating rod penetrates through the base and is rotatably connected with the base. The experiment table is reasonable in structure, power is provided through the air hammer, steel balls can be stably clamped, the steel balls are not prone to moving, the safety degree in the testing process is higher, meanwhile, the steel balls can rotate, strength testing of multiple positions of the steel balls is achieved, the strength testing blocks abut against the tops of the steel balls, and steel ball testing is more stable.

Description

technical field [0001] The invention relates to the technical field of test benches, in particular to a test bench for testing the strength of bearing steel balls with an automatic rotating test surface. Background technique [0002] The bearing components are composed of a positioning ring, a buckle plate, and a steel ball. Under the sliding cooperation of the steel ball and the positioning ring, the bearing realizes rolling and rotating actions. At the same time, in some environments, the shaft connected to the bearing It will bear a large force, so the strength of the steel balls that make up the bearing is the decisive factor that determines the strength adaptability of the bearing in this environment. Therefore, before the bearing is assembled, the strength of the steel ball parts that make up the bearing is tested. becomes more important. [0003] Most of the experimental machines used to test the strength of steel balls are air hammer equipment. When applying, put th...

Problems solved by technology

[0004] At present, the surface structure of the air hammer test bench in the prior art is single, mostly a horizontal platform structure. After the actual air hammer falls and hits the steel ball to be tested, due to the lack of a reasonable limit mechanism for the steel ball, it will occur Steel balls that are rolled and tested for compressive strength are mostly subjected to smashing pressure in one direction, and impact testing on all-round parts cannot be performed. Therefore, the existing air hammer test bench is used to test steel balls with better rolling properties. There are still the above-mentioned shortcomings in the impact test, so we have designed a test bench for bearing steel ball strength testing that automatically rotates the test surface to solve the above problems
