Definitions

  • the present invention relates to a hydropneumatic riveting gun according to the preamble of claim 1 (see GB-2 152 421).
  • the invention relates in particular, but not exclusively, to a hydropneumatic riveting gun for threaded rivets.
  • express reference will be made to threaded rivets without thereby restricting the scope of the inventive concept.
  • the stem of the hydraulic cylinder acts directly on a rivet holder.
  • the rivet holder comprises a rod or pin with a threaded end onto which the rivet can be screwed.
  • the application of the rivet occurs basically as follows: once the rivet has been engaged by the rivet holder, a first cutoff valve is opened by pulling the trigger on the gun handle; the opening of the first cutoff valve allows an external source of compressed air to be applied to a lower chamber of the pneumatic cylinder so as to push the piston in the pneumatic cylinder itself upwards.
  • a first cutoff valve is opened by pulling the trigger on the gun handle; the opening of the first cutoff valve allows an external source of compressed air to be applied to a lower chamber of the pneumatic cylinder so as to push the piston in the pneumatic cylinder itself upwards.
  • the piston travels upwards, its stem runs through an oil filled chamber located inside the handle and connected with the hydraulic cylinder. Under the pressure of the piston stem as it moves through the oil chamber, the oil is forced into the thrust chamber of the hydraulic cylinder in such a way as to cause a short but powerful backward movement of the piston of the hydraulic cylinder against the force applied by a return spring.
  • the pulling force applied to the rivet by this backward movement permits
  • the source of compressed air is connected automatically with an upper chamber of the pneumatic cylinder, the pneumatic piston moves down and the return spring of the hydraulic cylinder pushes the hydraulic piston forward, thus returning to the initial configuration.
  • the trigger When applying threaded rivets, the trigger also acts on a second pushbutton controlling a second valve which applies the source of compressed air to a pneumatic motor attached to the hydraulic cylinder casing and dynamically linked to the rivet holder. After being supplied with compressed air, the pneumatic motor turns the threaded rod of the rivet holder, thus disengaging it from the rivet that has just been upset in place.
  • Means are also envisaged to adjust the working stroke of the hydraulic piston in order to control the tightness of the rivet on the parts joined.
  • These means usually include a piston limit stop that can be positioned axially using a lock nut. During use, the limit stop is initially placed in such a way as to allow the shortest possible stroke of the hydraulic piston; a first rivet is upset in place and its tightness on the parts to be joined is checked. The required tightness can then be obtained by turning the lock nut to increase the piston stroke.
  • Hydropneumatic riveting guns have several advantages over conventional air-operated riveters; in particular, they are more powerful, reliable and longer-lasting.
  • a drawback to using them is that if the working stroke of the hydraulic piston is not set correctly, the tightness of the rivets may be incorrect and the rivet holder may even break.
  • a hydropneumatic riveting gun comprising a handle, a hydraulic cylinder mounted by the handle, and a rivet holding means mechanically and dynamically connected to the said hydraulic cylinder.
  • the document shows a pneumatic cylinder mounted by the handle and equipped with a piston running inside the casing of the pneumatic cylinder between a rest position and a work position and defining together with the cylinder a lower expansion chamber that can be connected with a source of fluid under pressure.
  • the lower chamber is connected by means especially designed to set the pressure in the said lower chamber to a predefined value when the chamber is connected with the source of fluid under pressure.
  • the object of the present invention is to provide a hydropneumatic riveting gun that is simple and economical in construction and that is capable of overcoming the abovementioned drawback.
  • the present invention is further defined in the characterizing portion of claim 1.
  • An advantage of the present invention is that it permits quick and easy adjustment of the rivet tightening force.
  • the numeral 1 indicates as a whole a hydropneumatic riveting gun comprising a handle 2, at the top of which there is a single-acting hydraulic cylinder 3 located and operating inside a casing 20, mounted by the handle 2, and at the bottom of which there is a double-acting pneumatic cylinder 4 inside which a piston 42, with a stem 40, moves.
  • the hydraulic cylinder 3 has a stem (not illustrated) which acts on a rivet holder.
  • the rivet holder consists of a rod or pin 5 coaxially integral with the stem of the hydraulic cylinder 3.
  • the rod 5 is housed in a sleeve 6 mounted on the casing 20 of the hydraulic cylinder 3 to which it is dynamically and coaxially linked.
  • the rod 5 has a threaded end 5a which protrudes from the front of the sleeve 6 and onto which a threaded rivet, not illustrated in the drawing, can be screwed.
  • the operation of the hydraulic cylinder 3 makes it possible to fix in place a rivet that has been screwed onto the threaded end 5a of the rod 5.
  • the numeral 19 indicates a ring nut used to adjust the stroke of piston of the hydraulic cylinder 3 by axially positioning a limit stop, of a known type and not illustrated in Fig. 1, inside the casing 20 of the hydraulic cylinder 3, which acts directly to stop the piston in the cylinder 3.
  • the handle 2 has a trigger 7 consisting basically of a lever of type one whose arms are used to operate two cutoff valves 8 and 9 which drive the pneumatic motor 10 and the pneumatic cylinder 4, respectively.
  • the pneumatic motor 10 is mounted by the casing 20, coaxially at the rear end of the hydraulic cylinder 3, and it is dynamically linked in a known manner (not illustrated) to the rod 5. By opening the valve 8, the user can operate the motor 10 to turn the rod 5 in one direction to screw the rivet onto the rod 5 and then in the other direction to unscrew it once the rivet has been fixed in place. In some cases, the rivet can be screwed on automatically by placing the rivet on the threaded end 5a and pressing on it lightly.
  • a fitting 11 which, as explained in more detail below, is connected to an external source of fluid under pressure, preferably air, which is not illustrated and which flows through the cutoff valves 8 and 9.
  • the inside of the handle 2 forms a chamber 12 full of hydraulic oil, communicating (in a manner not illustrated) with the hydraulic cylinder 3 and in which the stem 40 of the pneumatic cylinder 4 piston 42 runs.
  • the cylinder 4 also comprises a cylindrical casing 41 at the bottom of which there is attached a base 44 which, together with the casing 41 and the piston 42, defines a lower chamber 4b.
  • the piston 42 which runs along the lining of the casing 41 from a working position, where it actuates the hydraulic cylinder 3, to a rest position, from where it started before being driven along the working stroke, separates the chamber 4b from an upper chamber 4a which, in relation to the piston 42 itself, is on the side opposite the chamber 4b.
  • the chamber 4b constitutes the expansion chamber for the air under pressure from the external source, enabling the piston 42 to effect its working stroke to drive the hydraulic cylinder 3.
  • the base 44 is attached to the bottom of the casing 41 by means of a cover 43 which is screwed directly onto the casing 41.
  • the handle 2 is also equipped with a distributor valve 13 of known type connected to the compressed air ducts, some of which are shown in Fig. 1, labelled 21, 22, 23, 24 and 17. These ducts connect the chambers 4a and 4b of the pneumatic cylinder 4 with the compressed air source and with the atmosphere.
  • the duct 21 is connected directly, in a manner not illustrated in Fig. 1, with the duct 22 which leads to the source of compressed air, again through the valve 13.
  • the duct 21 is also connected, through the valve 9 in a manner not illustrated, with the duct 23 which is in turn connected with the distributor valve 13 through a branch duct 23a which leads into the valve 13 on the side axially opposite that visible in Fig. 1. Therefore, when the valve 9 is opened, the duct 23 is crossed by the same flow of air under pressure as the duct 21.
  • the distributor valve 13 is preferably of the type described in Italian utility model patent No.208.712, by the same Applicant.
  • the distributor valve 13 is structured in such a way that, under rest conditions, chat is to say, when the cutoff valve 9 is closed, the duct 24 connects the upper chamber 4a with the compressed air source and with the atmosphere; these conditions being reversed when the cutoff valve 9 is opened, that is to say, the lower chamber 4b is connected with the compressed air source through the duct 17.
  • the difference in pressure that is created between the chamber 4b and the chamber 4a pushes the piston 42 along the lining inside the cylindrical casing 41 to its working position opposite to that illustrated in Fig. 1.
  • the base 44 of the pneumatic cylinder 4 has a recess 14 in it to accommodate a pressure regulator 30.
  • the pressure regulator 30, of known type comprises a first fitting 31, for high pressure, a second fitting 32, for reduced pressure, and a screw 34 for regulating the reduced pressure, equipped with a stop nut 35.
  • the screw 34 is located in a place that can be easily accessed by an operator.
  • the out end of the reducer 30 is connected through the second fitting 32 to a rapid release valve 36, illustrated in an enlarged view in Fig. 3.
  • the base 44 of the pneumatic cylinder 4 also has a duct 15 made in it whose opposite ends lead into the lower chamber 4b and into the reduced pressure fitting 32 through the valve 36 (Fig. 3).
  • the base 44 there is also a compartment 16 which is connected directly to the high pressure fitting 31 on the side facing the reducer 30 and into which the duct 17 leads on the opposite side, the duct running through the inside of the cylindrical casing 41 and crossing the chambers 4a and 4b and the piston 42 through airtight seals, the piston sliding on the surface of the duct 17 through an airtight seal (18).
  • the duct 17 ends in the compartment 16 and crosses the base 44, air leakage being prevented by a seal 18 placed between the duct 17 and the base 44.
  • the compressed air source is connected with the duct 17 and, hence, with the compartment 16.
  • the pressure in the compartment 16 is reduced by the reducer 30 to a preset optimum value for the operation of the gun 1. Usually and preferably, the pressure is reduced to a value below 6 bars.
  • the reduced pressure is applied to the lower chamber 4b through the duct 15.
  • the pressure in the lower chamber 4b remains at a constant value less than the pressure supplied by the compressed air source, irrespective of the pressure upstream of the reducer 30 and of the flow rate through the reducer itself.
  • valve 9 is open.
  • This regulated pressure value can be varied, in a known manner, by acting on the adjustment screw 34.
  • the pressure in the lower chamber 4b is greater than the pressure in the upper chamber 4a which communicates with the atmosphere through distributor valve 13.
  • the piston 42 and its stem 40 are raised, thus compressing the oil in the chamber 12 to drive the hydraulic cylinder 3.
  • the thrust on the pneumatic piston 42 and, hence, the thrust transmitted by the latter to the hydraulic cylinder 3 cannot exceed a preset upper limit value.
  • the valve 36 consists of a body 37 which, on the side opposite the side that which is in contact with the reducer 30, presents a rapid release nosepiece 38 that is connected directly with a release hole 33.
  • the valve body 37 has a first hole 25 and, at the duct 15, a second hole 26.
  • a shutter 39 Inside the valve body 37, between the nosepiece 38 and the second fitting 32, there is a shutter 39 with a lip seal 29 round its perimeter.
  • the shutter 39 can slide inside the valve body 37 between two limit positions, the first to close the nosepiece 38 and the second to close the first hole 25.
  • the first position occupied by the shutter 39 is illustrated with a dashed line in Fig. 3.
  • the shutter 39 When the flow of compressed air reaches the second fitting 32, the shutter 39 is moved towards the position in which it closes the nosepiece 38 and the air can reach the lower chamber 4b through the duct 15.
  • the lip seal 29, whose free end is located at the edge of the hole 26, is moved by the air flow allowing the air to reach the chamber 4b and to push the piston 42 upwards along its working stroke.
  • the duct 24 is connected with the compressed air source so that the upper chamber 4a is filled with air and the piston 42 pushed downwards, forcing the air out of the lower chamber 4b through the duct 15.
