Description

The invention relates to mechanical assembly production and can be used to automate assembly processes, in particular in mechanical engineering when assembling screw connections, for example when assembling a bicycle unit (carriage shaft with a cone), screw the cone onto the shaft. A known assembly machine, a downstream housing, a transport device, loading devices with cutters along it, an assembly head with a movable and fixed clamping jaws having spring-loaded probes, a sorting mechanism and a control device associated with the sorting mechanism l, A disadvantage of the known automaton is the low reliability of the assembly, due to the fact that the automaton does not ensure quality control of the assembly at the assembly position. The purpose of the invention is to increase the reliability of the assembly by providing control of the assembly of the assembly. The goal is achieved by the fact that assembly machine 5, containing a housing, a rod transport, located along it boot devices with cutters, an assembly head with a movable and fixed clamping jaws having spring-loaded gauges. the sorting mechanism and the control device connected with the mechanism of sorting, the control device is made in the form of a spring loaded pawl and retainer installed on the conveyor belt, as well as a stop located on the body, while the dog is installed with the ability to interact with the spring loaded probe. the movable clamping lip, and with the sorting mechanism, and the stop is made in the form of a single-arm spring-loaded lever, - which has the ability to interact with the fixture of the control device. Figure 1 shows the assembly Av tomato, top view; 2 shows an assembly head, a general view of FIG. 3, a sorting mechanism, a general view; Fig. 4 is a kinematic diagram of the sorting mechanism in the case of a correct installation of the part; in Fig. 3 the same, in the case of incorrect installation of a part or not. 26 .2 The assembly machine (figure 1) consists of a table 1, a sucker-belt conveyor 2, kinematically connected to a camshaft (not shown) and installed on the table 1 according to the technological sequence of assembly of the device 3, setting shaft 4 (base part). assembly head 5 setting and screwed-in parts 6 (cone), mechanism 7 sorting, tray 8 unloading a defective unit, tray 9 unloading the assembled unit. A vibrating hopper 10 with a chute 11 is also mounted on the table 1 for orientation and feeding of the cone 6 and the store-type bunker 12 for shaft -4. In addition, on the table 1, a control device unlocking mechanism consisting of the stop 13 with a spring 14 is hinged on the rack. The assembly head 5 of setting and tightening the cone (figure 2) consists of a fixed clamping jaw 15 with a spring-loaded probe 16 installed on it kinematically connected through a lever 17 with a cutter 18, a movable clamping jaw 19 with a probe 20 fixed on it, performed in the form of a two-sided hitch, a pinch 21 with a tool 22, a lever 23 and an electric motor 24. The movable clamping sponge is kinematically connected to the cu Lacquer 25 of the camshaft of the automaton, and the spindle 21 through the lever 23 with the cam 26. The sorting mechanism (FIG. 3) consists of the movable jaw 27, the lever 28 of the top drive, 29, the double-arm lever 30, the single end of the pivotally connected to the slide, 31 The movable sponge 27 is kinematically connected to the cam 32, and the ejector 29 with the cam 33. The control device mounted on the rod 34 of the conveyor 2 consists of the dog 35 with the stop 36 and the retainer 37 and the stop 13. The assembly machine works as follows. The shaft 4 from the hopper 12, the compartment being connected to the device 3, is pushed by the conveyor 2, which reciprocates, to the position of the Assembly. The movable clamping jaw 19 of the assembly head 5, gripping the shaft 4 of the rod conveyor 2, is lifted by the cam 25. The shaft 4 is clamped between the shaft 3

Vision 15 and movable 19 jaw heads. When this shaft 4 is affected. on the spring-loaded probe 16, which in turn through the lever 17 acts on the cutter 18. In the feed tray 11 of the vibrating hopper 10, the cone 6 is cut off, which falls into the receiving slot of the assembly head 5. Under the action of the cam 26 of the camshaft, the lever 23 brings the tool 22 mounted on the spindle 21, which receives rotational motion from the electric motor 24, to the cone 6 and then moves it further onto the shaft 4. The cone 6 is baited and screwed in until it stops. In its final position, the cone 6 acts on the probe 20, made in the form of a two-arm. In this case, the upper end of it is in contact with the screw-on cone 6, and the lower end acts on the control device of the dog 35, drowned it. In this position, the pawl 35 is held by the latch 37. Upon completion of the operation, the shaft 4 with the screwed-on cone 6 is lowered by the movable sponge 19 and installed on the rod conveyor 2, which transfers it to the sorting position of the assembled units. At the same time, the assembled assemblies are further assembled, and the assemblies in which the coyus turned out to be unreleased or there is no withdrawal at all to the outlet tray 8 to the marriage receiver. If there was a screwing cone 6 to its final

Position (Fig. 4) the dog 35 by the stop 36 acts on a double-arm lever 30, which advances the slider 31. Thus, the relocation of the ejector 29 is blocked. The movable sponge 27, driven by the cam 32, removes the assembled unit from the rod conveyor 2 and holds it in place that position. Boom 34

0, the rod conveyor 2, carrying the control device 35-37, goes back a step. When this latch 37 runs over the stop 13 of the unlocking unit, freeing the dog 35.

5 Dog 35 comes to its original position. The cam 32, turning, lowers the moving sponge 27, and the assembled assembly enters the receptacle 9 through the discharge chute 9.

When the cone 6 is not loosened on the shaft 4 or the cone 6 is absent. (Figure 5) the dog 35 remains in the unlocked position, respectively, the stop 36

5 will not interact with the two shoulders lever 30, which will remain in its original position, and the slider 31 will not block the ejector lever 28 of the ejector 29. Therefore, the latter by moving from

The cam 33 through the lever 28 will push the unassembled assembly from the movable jaw 27, which at this moment is in the upper position, along the discharge chute 8 to the scrap receiver. The invention allows to increase the reliability of the assembly.
