Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Electric tools are widely used in production and life, and their operating performance directly affects the safety of relevant personnel at work. The cutting and bouncing energy comprehensive test bench of the electric tool of the present invention is composed of three parts: the design, detection and analysis of the transmission device, the establishment of the model, and the design of the clamp body, including the wooden board clamp and the electric circular saw clamp.

[0020] Such as Figure 1-5 As shown, the electric tool cutting bounce energy comprehensive test bench of the present in...

Abstract

The invention relates to an electric tool cutting bounce energy integrated test experiment table. A rack assembly is internally provided with a transmission device. The rack assembly is provided with an electric disk saw fixing device, a cylindrical conduit guide device and a wooden board clamp device thereon. In the experiment table of the invention, a gear cylindrical cam transmission mechanism and a cable track are selected to determine the bounce position of an electric tool, and based on the transmission mechanism composed of a cylindrical cam, gears and bearings, the clamping device for a wooden board in the cutting process of an electric saw and an electric tool fixing and relaxation device are designed. The cylindrical cam and the gear transmission mechanism can be used for completing the lateral movement of the wooden board according to a given motor, the lifting height of the electric saw can be measured by a measuring bar through the relaxation of the clamp when the electric saw is at work, and thus the corresponding data to the cutting bounce energy of the electric tool are obtained.

Description

technical field [0001] The invention relates to a cutting bounce energy testing device of an electric circular saw, in particular to a fixing method of the electric circular saw, a board clamping method and a bouncing height measuring method. Background technique [0002] With the continuous development of science and technology and the continuous improvement of mechanization level, people have higher and higher requirements for the safety of electric tools. There are three requirements in the study of electric circular saws: one is to test the strength of the recoil force produced by the same type of circular saws produced by different manufacturers during the working process; the other is to complete the fixing of the circular saw so that corresponding The measures to ensure that the chainsaw works in the best condition, and the third is to complete the fixing and returning of the cutting material, and perform multiple measurements to make the test data reach higher accura...
