Description

The invention relates to the field of engineering, in particular to devices that provide progressive step-by-step movement of an object.

The purpose of the invention is to expand the functionality.

The drawing shows a structural diagram of a hydraulic device for feeding a workpiece.

The hydraulic device for supplying the workpiece includes a housing 1 of a drive cylinder, in the inner cavity of which is bounded by side walls 2 and 3 a piston 4 with a hollow rod 5 is placed. The piston 4 forms two working chambers 6 and 7 in the inner cavity of the housing 1 5, a housing 8 of the control cylinder is attached, in the internal cavity of which, bounded by side walls 9 and 10 and the internal hollow sleeve 11, a piston 12 is placed. The piston 12 forms two working chambers 13 and 14 in the internal cavity of the housing 8 and is equipped with an alkatel 15, passed through the side wall 10 and sealed in it. The pusher 15 is rigidly connected to the half coupling 16. Through the rod 5 and semi-bushing sleeve 11, the rod 17 is rigidly connected with the movable object 18 and having a working surface 19 in the form of non-braking sparse. On the rod 17 of the installation;: a new free coupling half 20 in the form of a nut, supported through the bearing assembly, for example, in the form of two radial thrust bearings 21 and 22 rolling onto the housing 8. The pusher 1 with the coupling half 16 is equipped with means to prevent their rotation relative to the housing 8, made, for example, in the form of peripheral placement of the pusher 15 in the wall 10 of the housing 8. The housing 8 is provided with means for preventing its rotation relative to the housing 1, made. For example, in the form of rollers 23, resting on the plane 24 of the housing 1. The working chambers 6, 7, 13 and 14, respectively, have channels 25-28 for the passage of the working medium. The device is equipped with means for adjusting the stroke of the rod 5, executed, for example, in the form of a casing 29, covering the brush 5 and attached to the housing 1

and in the housing 29, an adjusting nut 30 with a fixing bar 31 and a limb 32 is mounted on the thread.

Hydraulic device for supplying the workpiece 5 work-. melts as follows.

In the initial position shown in the drawing, all working chambers 6, 7, 13 and 14 are de-energized. The working medium under pressure from the source of the working medium through a switchgear (not shown) delivers into the chamber 13, and from chamber 14 is removed for discharge. As a result, the engine piston 12 pusher 15, acting on the coupling half 16, leads it into

contact with the free coupling half 20. After that, the pressure of the working medium in the chamber 13 only provides an overlap of the coupling of the coupling halves 16 and 20.

Next, the working medium is supplied to the chamber 7 of the drive cylinder, and from the chamber 6 is removed for discharge. The movement of the piston 4 together with the housing 8 causes the movement of the rod 17, and with it the moving object 18. The latter rigidly holds the rod 17 against rotation by contacting the rod 17 and interacting with the movement surface. After completion of the stroke of the piston 4 (the reduced object 18 thus made one step), i.e. when it stops at the side wall 3, the working medium is fed into the chamber 14 of the control cylinder, and from the chamber 13 is removed to the dump. As a result of the movement of the piston 12, the pusher 15, carried away by the coupling half 16, removes the latter from the coupling half 20. Next, the working medium is supplied to the chamber 6 of the driving cylinder, and from the chamber 7 is removed for resetting. Moving the piston 4 together with the housing 8 causes the half coupling 20 to rotate in the bearings 21 and 22 along the threads of the rod 17. The latter remains stationary, as it is connected with the drive object 18. At the end of the stroke of the piston 4, i.e. when it goes to the lateral wall 2, the operation cycle of the device is completed and it comes to its initial state. After this, the second step can be performed in the same way, etc.

If the desired pitch is less than the stroke of the piston 4, the adjusting nut 30 is screwed to the required size.

Well, in the casing 29, controlling the limb 32 relative to the fixing bar 31, the required amount of reducing the stroke of the piston 4. When working with a reduced step of displacement, the piston 4 completes its cycle, not up to 12110194

rum in the side wall 2, and focusing the end of the stem 5 into the adjusting nut 30.

Thus, the device allows to change the step size of the object in a wide range.
