Definitions

  • This Invention deals with the problem of holding firmly an object to be worked on manually or by a machine, e.g. in milling, bending etc.
  • the present patent eliminates these problems.
  • THE ESSENCE OF THE INVENTION The primary purpose of the Invention is to ensure that the workpiece is efficiently and firmly held, always at four points or in two lines, no matter how parallel- running it is, with prevention of upward gliding, loss of parallel or vertical line in relation to the vice guides.
  • the secondary but also vital purpose is to provide much smaller tightening forces by means of a flexibly adjustable slide. This solution is applicable to all types of vices, mechanical, hydraulic or pneumatic.
  • the technical novelty of the Invention is as follows:
  • the nut holder and the truncated reverse cone-shaped nut keep the vice body and the slide together, acting, at the same time, as a pusher in the direction of tightening or disengagement, enabling the slide to rotate around the nut holder and nut axis, which in turn allows self-adjustability, whereas the conical shape of the nut prevents the slide from rising and instead with its final tightening force brings the slide to the vice body; at this stage the vice becomes a single whole.
  • Fig. 4 The nut holder and truncated reverse cone-shaped nut as it looks in real space, with a part of the threaded spindle Fig. 5 - Rear part of the vice as it looks in real space, in this case with hydraulic joint tightening
  • FIG. 6 A-A' cross-section of only the hydraulic part ending with a part of the threaded spindle having an ending identical to "MECHANICAL TIGHTENING" (Fig- 2)
  • Fig. 7 A-A' cross-section of only the working part of the hydraulic system in the joint position after final tightening, with the handle removed.
  • the Invention can help make a practical, safe, accurate and useful vice at a low cost, including essential improvements compared to the existing vices.
