Description

chains 1 and the outer events of these chains.

The single bottom of a roller chain usually consists of alternating external and internal links with relative mobility. Both external and internal links are made of two plates: the first ones are pressed on the axis, and the second ones are mounted on the sleeve. The sleeves are attached to the axes of the conjugate links and form a hinge.

Chains 1 rounds the machine bed 5 using the sols 6 and rollers 7 fixed on the 3Be bed. In the lateral deepening of the bed 5 there is a tensioning device 8 installed between the links in the roller chain 1 dL and the clearance of the gaps. are closed chain.

Clips 4 are made of sheet material and rigidly connected to two straps 9 installed on the underside of the flap 4. The ends of the mating axes 10 of the roller chain 1 are pressed into the outer ends of the slats 9. Thus, the shields 4, connected to the slats 9, act as external links of roller chains, and the role of a hinge joint is performed by roller chains 1. The connection of the plate 4 to the roller chain 1 can be made on either of the outer sides of the roller chain or on the two outer sides of the roller chain simultaneously.

On each side of the table 2, the number of plates 4 is required, which is necessary to overlap the guides 3 on the frame along the entire length, when the table 2 is in the extreme position at the other end of the frame 5, Receivers 11 for chips are installed on both sides of the machine bed 5

The device works as follows.

When moving the movable organ (table) 2 relative to the frame 5, for example, left to the right, the movable organ (table) 2 t does not have roller chains 1 with guards attached to them 4. When roller chains 1 bend around asterisks b and go to the straight line above the directions machine 3,

The flaps 4 smoothly overlap each other, eject and completely overlap the guides 3 of the machine. When moving the rolling organ 2 from right to left, the same happens, in the opposite direction. When struck on the flaps, 4, during the return stroke of the table 2, is assembled in the receiver 11.

invention formula

A device for guiding machine guides with reciprocating movement of a movable organ connected to the latter, including a ball. Recurring articulated elements, characterized in that, in order to ensure reliable operation of the device with increased numbers of double strokes of the under-movable In the case of an organ, the protective elements are made in the form of plates connected to two roller chains and which are simultaneously external links of both chains.

Claims (1)

Claim The device for protecting the guides of the machine with reciprocating movement of the movable member connected to the latter, including protective elements articulated with each other, characterized in that, in order to ensure the reliability of the device with increased numbers of double strokes of the movable member, the protective elements are made in the form of guards connected with two roller chains and being simultaneously external links of both chains.
