Description

(54) CLAMPING DEVICE
one
The invention relates to machine tool construction.
On the main auth, sv. In 72272B it is known a clamping device, in the case of which clamping elements are placed, moved by means of a screw, which are placed on the cheeks of the U-shaped bracket 1.
A disadvantage of this device is its low centering accuracy.
The purpose of the invention is to improve the accuracy of centering.
This goal is achieved by the fact that the device is equipped with supporting straps, fixed on the body from the outside of the sliders and collets with nuts, one of which is placed between the clamping element and the screw, and the other between and. screw.
: At the same time, in order to limit the clamping force, it is provided with a ratchet mounted on the free end of the clamping screw.
.In FIG. 1 schematically shows the proposed device, the section in FIG. 2 - the same. top view with frequency sections in fig. 3 - section. in fig. 2
The clamping device consists of a KOI trigger 1, sliders 2 and 3, respectively, attached to the clamping elements. max (prisms) 4 and 5, installed with the possibility of moving along. the longitudinal axis P - shaped leading bracket 6, at the ends of which the slider 2 is fixed, and the slider 3 is placed in the opposite part of the driving bracket 6,
10 clamping screw 7 with right and left threads connected to slide 3 and leading bracket 6, stop 8 fixed on housing 1 outside slide 2 and 3 of support bars 9 and 10, collets 11 and 5 with petals, clamp nuts 13 and 14 balls 15 and separators 16 and 17 connecting the balls to each other.
In the leading bracket 6 and the slider 3 coaxially made holes 18 and 19,

Claims (2)

  1. 20, which are mounted to the collets 11 and 12 and the clamping nuts 13 and 14 located on the outside of the collets. In the sliders 2 and 3 and the support bars, guides are mounted in the collets 11 and 12, on the inner surface of the petals of which there is a thread that is engaged clamp screw 7. Balls 15 with separators 16 and 17 are placed 30 between sliders 2 and 3 and bearing bars 9 and 10 in guide slots 20 and 21. A ratchet 22 is fixed to the free end of clamping screw 7. The clamping device operates as follows. When the ratchet 22 rotates, the clamping screw 7 rotates, braked from axial displacement by the stop 8. The action of the collet 11 and 12, the petals of which are pressed along the thread to the clamping screw 7 by means of the clamping nuts 13 and 14, the latter slide the slides 2 and 3 with the prisms attached to them 4 and 5, the centerpiece of the part 23. In this case, the slashes 2 and 3 move on the balls 1 located in the guide slots 20 and 21 between the sliders 9 and 10. When the ratchet 22 rotates in the opposite direction, the part 23 is released. In the proposed device, due to the use of grips with clamping nuts for the transfer from the clamping screw to the slide and the drive bracket, the backlash in threaded joints is eliminated. At the same time, the use of the ratchet provides for the limitation of the force for clamping the part while centering, in consequence of which the deforming of the clamping screw and the centered part is eliminated. In addition, placed on the balls, pressed by the support bars during their installation, eliminates the backlash of the sliders. Claim 1, Clamping device according to ed. No. 722728, characterized in that in order to increase the centering accuracy, the device is equipped with support bars fixed on the housing from the outside of the sliders and collet mI with clamping nuts, one of which is placed between the clamping element and the screw, and the other between the bracket and screw.
  2. 2. The device according to claim 1, characterized in that, in order to limit the clamping force, it is provided with a ratchet mounted on the free end of the clamping screw.
