TH1970B - Machines with interchangeable moving heads - Google Patents

Abstract

Machines with replaceable moving heads which has a machine base on which the upper part has a sliding platform and has an operating unit on it. and is driven by an electric motor. and stationary rear rails and a number of head units are mounted on the movable rails. with an index platform to control and select one of the head sets in the position to perform the desired operation The movable part of the rail is extended to the operating unit by means of a mounting arm that consists of a cylinder. and the piston rod, which protrudes from the piston inside the cylinder There is a spring inside the cylinder at the front of the piston. to push the piston rod into the cylinder assembly Including a system to supply the pressure of the fluid from the pressure source into the cylinder. to help increase the pressure of the spring There is also a system to detect the working position of the operating unit. to prevent stalling or the burden on the operating unit due to the high inlet pressure of the pumping regime. There will be a way to drain such pressure from the cylinder as needed.

Claims (2)

1. A machine with an interchangeable head unit, in which the upper machine base has a sliding platform that can be moved in the forward direction. And back, with the operating unit that Driven by electric motor There is a ring rail consisting of a movable front rail and a stationary rear rail arranged around the unit. A number of head sets are arranged. And mounted on such ring tracks And can be rotated along the ring track with an index platform mounted above the head unit To set a specific set in the desired position on the movable rail. Movable rail And the operating unit is held together by a holding arm made of a cylinder. And a piston rod that holds and protrudes from the piston in the said cylinder And the piston rod is pressurized in the direction that enters the cylinder by spring. The fluid pressure source, such as air pressure or the like, is provided to the cylinder of the arm through a connecting pipe. To provide additional pressure to the pressure of the spring to shorten the support arm by the pressure of the fluid applied to the cylinder 2. The machine, as specified in claim 1, in which there is a component for detecting the reverse position. And the forward moving position of the operating unit, which will be attached to the movable rail In order to make the arm such that the work switch between conditions. When the detector element is in the working state, the cylinder is connected to the pressure source. And the pressure of The fluid is fed into the cylinder. With the condition when the aforementioned detecting parts are not in working state. Which the cylinder will connect to the outlet outside To drain the pressure of the fluid from the cylinder
