Definitions
- Hand-operated cleaning device for the gas nozzle of a welding torch
- the invention relates to a hand-operated cleaning device for the gas nozzle of a welding torch according to the preamble of claim 1.
- cleaning devices are used for automatic welding with the aid of a robot, into which, for example, the robot inserts the nozzle in order to position them again for welding processes after cleaning.
- the object of the invention is to provide a hand-operated cleaning device that allows the nozzle of a welding torch to be cleaned quickly, inexpensively and precisely.
- the knives or milling tools provided engage in the nozzle in a precisely positioned manner during the cleaning process. Characterized in that by pressing the nozzle holder down, the knives are rotated by the force exerted by hand on the nozzle holder, safe and reliable cleaning of the nozzle is ensured without the need for expensive means, for example for driving the milling tools or knives or for centering these tools.
- Figure 1 shows the view of the device, partially cut.
- FIG. 2 shows the side view of the device of FIG. 1 in the direction of arrow II:
- Fig. 3 is a plan view of the device in the direction of
- the cleaning device has a receptacle (1) for the nozzle (2) to be cleaned.
- the receptacle (1> has at its lower end a plate (3) with a conical opening (8) into which the conical part of the nozzle fits.
- the plate (3) is interchangeable with other plates which have openings with an angled diameter in order to accommodate nozzles of other dimensions.
- the nozzle is precisely positioned by hand in the receptacle (1).
- the receptacle (1) is arranged in a plate (5) which carries ball bearing bushes (6) and which engage through the guide rods (7) of the part fixed to the device.
- the guide rods (7) are firmly connected to a base plate (10).
- the plate (5) with the nozzle receptacle (1) can be moved downward on the guide rods (7) by pressure on the nozzle (2) in the direction of the arrow (20). The displacement takes place against the pressure of springs (9), so that after the pressure on the nozzle (2) has ended and the plate (5) has been pressed down by hand, the plate (5) is shown in FIG. 1 posed starting position again.
- the springs (9) are supported on the base plate (10).
- a ball bearing bush (12) is arranged in the base plate (10), in which a shaft (13) of a sleeve (14) is rotatably mounted in the direction of the arrow (15). The rotation takes place around the extension of the axis A-A of the nozzle (2).
- the sleeve (14) has two pins (16, 16a) which engage in screw-in-recesses (17, 18) of an extension (19) of the nozzle holder (1).
- the sleeve (14) carries the knives (21).
- the nozzle (2) To clean the nozzle (2), it is inserted into the conical opening (8) of the plate (3) of the nozzle holder (1).
- the nozzle is fixed in the opening (8) of the plate (3) and is held in the axially aligned position by the fixing and tensioning screws (4).
- When exercising one Pressure on the nozzle (2) by hand in the direction of the arrow (20) moves the disc (5) and thus the sleeve (19) in the direction of the arrow (20) downwards.
- the pins (16, 16a) of the sleeve (14) engaging in the thread-like recesses (17, 18) rotate the sleeve (14) about their axis in the direction of the arrow () when the nozzle moves downward in the direction of the arrow (20).
- the knives (21) penetrate into the nozzle while rotating the gas nozzle (2). Here they scrape the inside of the nozzle (2) free of welding residues.
- the nozzle can be lifted out of the device again without any further measures, and its interior is now usually sprayed with a non-stick agent.
- the base plate (10) has bores (23) by means of which it can be fastened to a base by means of screws.
- the base plate (10) also carries a pin (22) which the nozzle receptacle (1) with its extension sleeve (19) hits when pressed down.
- the pin (22) thus limits the stroke movement of the nozzle holder (1).
- the pin (22) can be designed as a screw in order to be able to set the stop position of the nozzle holder (1).
- the nozzle (2) can advantageously be clamped in the nozzle receptacle (1) by hydraulic or pneumatic means and thus the Nozzle receptacle (1) must be designed to be device-specific.
- the sleeve (14) can be raised and lowered in a kinematic reversal of the method of operation described. The operation of this training is the same as described with reference to the figures.
- the sleeve (14) and possibly the base plate (10) are lifted, the sleeve (14) sets the knives (21) in rotation about the axis AA. The knives are inserted into the nozzle (2) and scrape them freely.
- the nozzle (2) remains fixed in its position.
- the sleeve (14) can be raised hydraulically or pneumatically, possibly against the pressure of the springs (9), which in this embodiment seek to do so after the rotating knives (21) have been inserted into the nozzle (2) (14) to push back to their starting position.
