(54) ASSEMBLY FORM

voutochna golikovoy CHAIN

I

The invention relates to a chain iipoHS production and can be used in enterprises manufacturing sleeve-roller chains.

A device is known for assembling links of drive bush-roller chains in which components: the elements are fed to a rotating rotor, which is transferred to the pressing position, and later to the repressing position (1.

the prosperity of this device is that the upper and lower plates move along a curved path, the elements of the chain are moved from position to position, and the assembly process is carried out in two positions. All this greatly complicates the technological process of work and the tool that accomplishes this assembly. transferring the link from one working position to another, which leads to complication of the assembly process and the device that performs this assembly.

It is also known to assemble an Even, consisting of a base, with sliders mounted on it (feeding component components of the link), upper and lower tools for pressing the link elements at two working positions and feeders rigidly attached to the base 2.

The disadvantage of such a device is its complexity, since it requires additional devices for transferring parts and assemblies from one tool to another.

The purpose of the invention is to reduce the time, i.e. productivity increase.

Claims (2)

The goal is achieved by the fact that the device contains mounted on the supply components-elements feeders, horizontal directions, slides mounted on these guides with the possibility of movement, one of which is spring-loaded, pressing-on components on the base and located above and below from the slider, which feeds these elements, the spatulas of the component elements are rigidly connected to the spring loaded slider, at the same time the slider, which feeds these elements za1fessovki nodes, vtolnen in sets arranged one above the other are rigidly associated mezhlu a plate with through holes, forming the window for the passage komplektun Tsikh element and provided with abutments and retainers podaruzhinennymi. FIG. 1 shows a device for assembling a chain; FIG. 2 is a top view of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. one; in fig. 5 shows section A-A in FIG. one; in fig. 6–9 is a sequence (of the method steps. The device for assembling the link consists of a base 1 on which the sliders 2–4 are mounted on the sliders and sliders 5 and 6. The slide 5 is supported by a spring 7 and is rigidly attached to it feeders 8-11. The slider 6 consists of one-piece forming plates 12-16, which create functions for the passage of component parts: the top plate 17, the sleeves 18, the roller 19 and the bottom plate 20. The plates 13 and 16 have spring-loaded clips 21, and the plates 14 and 15 - spring-loaded latches 22 and 23. Feeders 8-11 have stops 24-27, which fit into the grooves for the passage of the components. The upper 28 and lower 29 pressing tools with spring-loaded clamps 30 and 31 are mounted with the possibility of vertical movement. The link assembly is performed as follows. Plates 17 and 20 The sleeve 18 and the roller 19 are fed through And, 8, 10 and 9 feeders (own weight), respectively, onto plates 13 6, 14 and 15 of creep 6, which moves them to position 6 of the assembly. Upper tool 28 and lower tool 29 are vertically displaced and clamps 30 and 31 center plates 17 and, as well as sleeve 18 and roller 19 (Fig. 7). After centering, the slider 6 is retracted to its original position (Fig. 8). When moving to the initial position of the plates 17 and 20, the bushing 18 and the roller 19, the abrasives 24, 27, 25 and 26 are fixed and, when the slider 6 is released, are fixed by the clips 21 and 22, i.e. Slider 6 is extra charged with accessories. The upper tool 28 and the lower 29 are again connected to vertical movement (Fig. 9), and an end occurs on pressing in, after which the upper tool 28 and the lower one return to their original position and the whole cycle repeats. When jamming any of the clustering elements, the spring 7 delivers under the action of the slide 5, which acts on the limit switch 32, giving a signal to stop the machine. Seizure of components is possible only when slider 6 is returned, since only in this case the plates, sleeves and rollers move along the windows of slider 6. Supply of components in parallel, one above the other straight rows, allows centering and assembly of the link in one working position , Ch1o greatly simplifies the assembly scheme itself and the device used to implement it. Claim device Assembling a stub-roller chain comprising mounted on the base of the feeders of component elements, horizontal guides of the crawler 1 mounted on these guides with the possibility of movement, one of which is spring-loaded, the assemblies of pressing on the mounting elements mounted on the base and located on top from the slider, which feeds these elements, characterized in that, in order to increase productivity, the feeders of the component elements are rigidly connected to the subs A slider, while the slider, which feeds these elements to the press-in assemblies, is made in the form of sets arranged. one above the other rigidly interconnected plates with through holes, which open windows and the passage of component parts, equipped with stops and spring-loaded latches.
