Abstract

The invention relates to a testing device for load of a jig saw, which is characterized in that the testing device comprises a load simulator (100), a jig saw fixing device and a frame (8), wherein the load simulator (100) comprises a mounting bracket (3), a magnetic powder clutch (4) and two rollers (1 and 2); the magnetic powder clutch (4) is arranged below the mounting bracket (3), and the output end of the magnetic powder clutch (4) is connected with the roller (2) through a one-way bearing; a cantilever of the jig saw fixing device is arranged at the outer side of the frame (8) and consists of a cantilever (5) and a fixing part (6); and a jig saw blade to be tested is arranged in a clearance between the two rollers and clamped by the two rollers. During the testing process of the jigsaw, the load under actual conditions is simulated through the magnetic powder clutch and the one-way bearing completely, and the actual cutting material is not needed during the testing process, therefore the testing device has the characteristics that the testing efficiency is improved, the testing material is saved, the testing cost is reduced, and the operation is simple and convenient.

Description

technical field

[0001] The invention relates to a jigsaw load testing device. Background technique

[0002] In 1947, the German company Bosch invented the world's first jigsaw. Curve saw is a kind of electric reciprocating saw that can be sawed according to the curve, also called combing machine and vertical saw. For sawing, you can also install sharp blades to cut rubber, leather, fiber fabrics, foam plastics, cardboard, etc. Jig saws are widely used in industries such as automobiles, ships, furniture, and leather, and are also widely used in wooden molds, handicrafts, scenery, advertising production, and repair industries.

[0003] The saw blade of the jigsaw is clamped on the jigsaw, and the saw blade moves up and down through the workpiece to be sawed. Usually, the teeth of the saw blade are forward, so when working forward according to the cutting track, the reaction force of the load will be generated. Under the action of load, the saw blade will fatigue and age aft...
