Description

The invention relates to a mechanized tool with automatic feeding fasteners and can be used to automate assembly processes.

The purpose of the invention is to increase reliability by ensuring that the screws are fixed at the initial moment of tightening.

Figure 1 shows the screwdriver, a longitudinal section; Fig. 2 is a view A of Fig. 3 shows a groove configuration on the surface of the feeder; figure 4 - section bb in fig 2; figure 5 is a section of the B-R in figure 4; figure 6 - section GG in figure 4.

The screwdriver contains a working tool 1 connected to a drive (not shown, body 2, mounted on it with the possibility of reciprocating motion receiving head 3, spring-loaded relative to body 2 by spring 4.

In the receiving head 3 there is an axial channel 5 for the working tool 1 and an inclined channel 6 for feeding screws. In the axial channel 5. An additional sleeve 7, spring loaded with spring 8, and the channel is installed. 6-for supplying the screws ends with a section 9 parallel to the channel 5. In the receiving head 3 there is a feeder 10 rigidly connected with a sleeve placed in the receiving head 3) D, on the side surface of which there is a longitudinal hole 12 with a screw section 13. With the groove 12 interacts the pin 14 of the rod 15, which is installed in the receiving head 3 with the possibility of reciprocating movement and is spring-loaded spring 16.

An adjustable stop 17 is mounted on the rod 15 to adjust to the desired length of the screwed in screw. The finger 14 is placed in the groove 18 of the receiving head 3, and on the feeder 10 is spring-loaded clamp 19. In

the cover 20 is provided with a groove 21 for the screw 22 and a window 23 for opening the pressure plate 19.

Screwdriver works as follows.

The screw 22 supplied with compressed air through the channel 6 falls on the clamp 19 of the feeder 10, where it is reliably held and. centered. When moving the screwdriver in the direction of the assembled parts 24 and 25 at the initial moment, the rod 15 touches the surface of the assembled part 24, the spring 16

compressed, and the finger 14, slides along the groove 18 of the receiving head 3 and interacts with the screw section 13 of the groove 12, rotates the sleeve 11. In this case, the feeder 10 rotates and

aligns the axis of the screw 22 with the axis of the channel 5 for the working tool, after which the finger 14 of the rod 15 slides along the groove 12, the feeder 10 does not rotate, the screw 22 is centered in the threaded

the opening of the assembled part 24, and the screw cap 22 rests on the sleeve 7, which is displaced relative to the receiving head 3 and pressed by the spring 8. When moving

screwing down the receiving head 3 stops, and the drive with the working tool 1 continues - from, the spring 4 is compressed and the screw 22 is tightened.

the clamp 19, which at this moment under the window 23, is pressed by the head of the screw 22, and after it has been completely turned back, returns to its original position. When the screwdriver retracted under

the action of the spring 16 rod 15

using a finger 14, the feeder 10 returns to its original position. The screw driver is ready for wrapping the next screw.
