Embodiment Construction

[0037] The following is attached with the manual image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 The present invention is described in detail.

[0038] Such as image 3 The initial state shown is a

[0039] The test sample 7 is placed on the sample lifting support platform 3 and fixed to the support platform 3 by the sample fixing pressing block 14 . The sample lifting and supporting platform part 3 cooperates with four lifting sliding bearings 4, four lifting rods 10 and the lower bottom plate slider 2, and is jointly fixed in the horizontal guide rail 1 of the equipment bottom plate 19. A horizontal telescopic cylinder 17 and a vertical telescopic cylinder 18 are installed on the equipment base plate 19 in addition. The horizontal telescopic cylinder 17 works in cooperation with the horizontal guide rail 1 to make the test sample 7, the sample lifting support platform 3, and the lower floor slide block 2 move in the horizontal direction together. The vertical...

Abstract

Belonging to the field of electrical product test equipment, the invention particularly relates to an electric circular saw shield rebound test device. According to a technical scheme adopted by the invention, the electric circular saw shield rebound test device includes an equipment base plate, a pair of guide rail parallelly arranged on the equipment base plate. A slideable lower baseplate sliding block is disposed on the guide rail, and is connected to a horizontal telescopic air cylinder. The lower baseplate sliding block is equipped with four lifting rods, and a sample lifting support platform passes through the four lifting rods and is connected to a vertical telescopic air cylinder. The sample lifting support platform is provided with a test sample mounting instrument. The equipment base plate is provided with a shield check block. The test device provided by the invention realizes systematicness, safety and reliability of electric circular saw rebound test, has an optimized structure, is convenient to operate, and improves the test accuracy and applicability.

Description

technical field [0001] The invention belongs to the field of electrical product testing equipment, in particular to a springback testing device for an electric circular saw shield. Background technique [0002] The electric circular saw is a tool that uses a single-phase series-excited motor as the power to drive the circular saw blade through the transmission mechanism for sawing operations. It has the characteristics of safety, reliability, reasonable structure, and high work efficiency. [0003] According to the requirements of chapter 17.101-durability test of the international standard EN60745-2-5, a durability test is required for the lower guard of the electric circular saw. Standard requirements: such as figure 1 The standard structure of the electric circular saw shown in is upper guard 1a, debris ejection port 2a, saw blade rotation direction indicator 3a, lower guard 4a, bottom plate 5a, riving knife 6a, lower guard opening indicator 7a, riving knife Seat 8a, sw...
