A kind of ct19 mechanism spring dismounting device and using method

Abstract

The invention relates to a CT19 mechanism spring disassembling and assembling device. The CT19 mechanism spring disassembling and assembling device comprises a support, wherein the support is formed by a surface plate and side plates. A clamping device, a limiting device and a stretching device are arranged on the support. The clamping device comprises clamping blocks, wherein the clamping blocks are arranged on a guide rod which is located between the side plates. The clamping blocks are lifted and pressed by a first press rod, and combination and separation of the clamping blocks are achieved through linkage between a first connecting rod and a first push rod, so that clamping of a spring is achieved. The limiting device comprises limiting clamping blocks, wherein the limiting clamping blocks are hinged. The limiting clamping blocks are lifted and pressed through a second press rod, and combination and separation of the limiting clamping blocks are achieved through linkage between a second connecting rod and a second push rod, so that limiting of the spring is achieved. By the use of guide grooves formed in the side plates, the stretching device stretches the spring through an insertion part inserted into the spring according to the lever principle of supporting rods, and disassembly of the spring is achieved in the stretching process. The invention further relates to an application method of the CT19 mechanism spring disassembling and assembling device. The CT19 mechanism spring disassembling and assembling device can be rapidly installed and fixed, accomplishes stretching and disassembling operation of the spring at the same time, avoids popup of the spring in the disassembling process, and can also conduct rapid assembly on a spring for replacement.

Description

technical field [0001] The invention belongs to the field of electric tools, and in particular relates to a CT19 mechanism spring dismounting device and a using method. Background technique [0002] The energy storage spring of the CT19 energy storage mechanism is an important accessory part of the operating mechanism, which stores energy for the closing of the mechanism. The spring needs to be disassembled and assembled when the tension of the spring is insufficient and needs to be replaced and when the energy storage motor is overhauled. Now because the placement position of mechanism is comparatively narrow, the tool that is not suitable for carrying out work on the spot causes dismounting spring time to be too long, and the safety of personnel can not be guaranteed. [0003] At present, in the process of installing or disassembling the energy storage spring, workers generally use a screwdriver to pry. There are several problems in the existing special CT19 mechanism spr...

AI Technical Summary

Problems solved by technology

Now, due to the relatively narrow location of the mechanism, there are no tools suitable for on-site work, resulting in a long time for disassembling and assembling the spring, and the safety of personnel cannot be guaranteed.

[0003] At present, in the process of installing or disassembling the energy storage spring, workers generally use a screwdriver to pry. There are several problems in the existing special CT19 mechanism spring dismounting device: one is that the energy storage spring can only be stretched After the energy storage spring is stretched, pull out one end of the energy storage spring with a tool or directly by hand. There are safety problems in the process of pulling out. The energy storage spring is easy to fall off from the disassembly device, and there is a risk of squeezing your fingers after falling off. Dangerous, easy to cause work injuries; second, most of the disassembly devices can only remove the energy storage spring, and cannot be used for the installation of the energy storage spring, and the utilization rate is low; third, the operation of the disassembly device is complicated, the operation time is long, and the efficiency is low

[0009] The overall weight of the CT19 mechanism spring dismounting device is heavy, and the operating space of the energy storage spring is operated within the original narrow range, which makes it difficult to use the dismounting device, and the operation of the spring installation is also complicated. If it is not installed for the first time , it is difficult to install the second time due to physical exertion
