(54) DEVICE FOR DETECTING ELECTRODES OF CONTACT DOT MACHINES

(57) The invention relates to mechanical engineering, in particular to the manufacture of devices for removing electrodes, and may find application in the manufacture of structures made by resistance spot welding. The goal is to increase operational convenience and reduce the time for clamping and removing electrodes. The device is equipped with an additional two shoulders lever 5, pivotally connected to the main lever. The working ends of the arms are hingedly connected to the prisms of the 1 and 2 bodies and have a rounded shape. Angular elements 10 are mounted on the working ends of the levers, and having the ability to move parallel to the axis of the hinge 7 connecting both levers. The reduction of the levers 5 and 6 clamp the electrode. Upon further mixing, the levers rotate relative to the axes of the hinges and slide along the plates 10 and 11 with their radius surface, which creates a force pushing the electrode. The device allows to simplify the design to protect the end of the electrode holder from deformation. 5 il.

The invention relates to mechanical engineering, in particular, to the production of devices for removing electrodes, and may find application in the manufacture of structures made by resistance spot welding.

The purpose of the invention is to increase operational convenience and reduce the time for clamping and removing electrodes.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a cross-section of the FIG. four.

The device comprises a housing consisting of two detachable prisms 1 and 2, having corrugated grooves forming an aperture for the electrode, and axes 3 and 4 executed in them, on which two shoulders are hingedly mounted levers 5 and 6 movably connected by a common axis 7, while the small arms of the levers have a radial surface 8, made ex10

the plates 10 and 11 to the end of the electrode holder and then clamping the electrode between prisms between prisms. After that, the reduced levers rotate relative to the axes of the hinges 3 and 4, while the radius surface 8 of the levers, sliding along the support plate 10 and 11, creates force pushing the electrode out of the electrode holder.

The use of the invention allows to simplify the design in manufacturing, to protect the end of the electrode holder from deformation, to reduce the clamping time and. removal of the electrode, improve operational convenience.
