Embodiment Construction

[0035] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0036] Such as figure 1 , Figure 3-Figure 8 As shown, a vacuum cleaner bellows rotating fatigue strength testing machine includes a base 2, an electrical box 4 arranged on one side of the base 2, and at least one set of counterweights 6 above the base 2, and at least one set of counterweights 6 are installed on the electrical box 4. Fixture 8, the structure of fixture 8 and counterweight 6 is the same, the clamping is simple and fast, and the clamping time is reduced. The mandrel 10 is connected with a transmission assembly 14 . Preferably, two groups of counterweights 6 are arranged above the base 2, two groups of clamps 8 are installed o...

Abstract

The invention discloses a dust collector bellows rotation fatigue strength test machine, comprising a pedestal, an electric cabinet arranged on one side of the pedestal and at least one group of counter weights arranged above the pedestal; the electric cabinet is provided with at least one group of clamps which are identical with the counter weights in structures; the clamp comprises a tension mandrel, a tension sleeve in cooperation with a tension mandrel screw thread pair; and the tension mandrel is connected to a transmission assembly. The invention has double motors and 6 working stations, and can perform multiple groups of tests; a ball head plunger is installed inside the clamp and can be installed on or disassembled from a rotation shaft, which is easy for the operation staff to clamp the product off-line; the clamps and the counter weights adopt identical structures and a principle and are easy to clamp; the free end of the tension sleeve is provided with a boss, which prevents the bellows from following up and slipping during the rotation; each working station has a limiting cylinder, which guarantees the test process to be stable; the transmission structure is simple and easy to maintain; the motor is equipped with an independent speed regulator, which is easy to regulate the speed; and the invention adopts the photo electric device, and stable and reliable in working.

Description

technical field [0001] The invention relates to a testing machine, in particular to a vacuum cleaner bellows rotating fatigue strength testing machine. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and telescopic direction. It is connected to the suction nozzle of the vacuum cleaner to realize the flexible rotation of the suction nozzle. Therefore, the rotational fatigue strength of the bellows directly affects the performance and performance of the vacuum cleaner. Reliability, in order to ensure that the bellows installed on the vacuum cleaner are qualified and improve the competitiveness of the enterprise, it is necessary to test the rotational fatigue strength of the bellows. The existing rotating fatigue strength test of vacuum cleaner bellows has the following defects: 1. The clamping is cumbersome and the work efficiency is low; 2. The test result is single and cannot meet t...
