Definitions
- the main object of the invention is to create a piston-cylinder type actuator and an end wall mounting method for the same by which the end wall and cylinder tube design as well as the assembly work is substantially simplified and, thereby, less costly.
- Fig 1 shows a longitudinal section through a piston-cylinder type actuator according to the invention.
- Figs 2a-c illustrate in three steps the end wall mounting method according to the invention.
- Fig 3 shows the completed end wall mounting carried through as illustrated in Figs 2a-c.
- Fig 4 shows an enlarged fraction of Fig 3.
- Fig. 5 shows an end view of the device in Fig 3.
- the actuator shown in Fig 1 comprises a cylinder tube 10 with pressure medium communication ports 11, 12 and two end walls 13, 14.
- One of the end walls 14 has a central opening 16 through which a piston rod 17 extends.
- the latter has a threaded bore 18 at its outer end for connection to an external load and a threaded inner portion 19 by which a piston 20 is rigidly attached.
- the piston 20 carries both a seal ring 22 and guide elements 23 for contact with the cylindrical inner surface 24 of the cylinder tube 10.
- a seal ring 25 is mounted in the end wall opening 16 to sealingly cooperate with the piston rod 17.
- a coil spring 27 is inserted between the front end wall 14 and the piston 20 to exert a bias load on the latter towards the rear end wall 13.
- the end walls 13, 14 are formed with circumferential grooves 28 and 29, respectively, for supporting seal rings 30, 31.
- the end walls 13, 14 are also formed with circumferential mounting grooves 33, 34, which are engaged by lock lugs 35, 36 extending radially inwardly from the inner surface 24 of the cylinder tube 10.
- the lugs 35, 36 which extend throughout the inner circumference of the cylinder tube 10, are formed by plastic deformation of the latter and form together with the grooves 33, 34 a rigid and permanent mounting means for the end walls 13, 14. Thereby, the flat end surfaces 37, 38 of the end walls 13, 14 are flush with the end surfaces of the cylinder tube 10.
- the end wall mounting is carried out by means of a mounting tool 40 which serves both as an end wall guiding and introduction means and as a cylinder tube upsetting pressing tool.
- the tool 40 is formed with a flat front surface 41 and an annular ridge 42 of substantially rectangular cross section and protruding in front of the front surface 41.
- This ridge 42 has an inner diameter to fit the outside surface 37 of the end wall 13, and the axial extent of the ridge 42 is equal to the distance between the outer end surface 37 of the end wall 13 and the mounting groove 33.
- the width of the ridge 42 is chosen so as to generate a lug 35 of a correct size to match the groove 33 when pressed against and into the end surface of the cylinder tube 10.
- the deformation ridge 42 engages the end surface portion 43 of the cylinder tube 10 located at the inner circumference of the latter. See Fig 2b.
- the embodiments of the invention are not limited to the above described example which includes the formation of a single annular lock lug 35 extending over the entire circumference of the cylinder tube 10.
- the lock means may comprise a number of shorter lugs distributed over the circumference of the cylinder tube 10, and the mounting groove 33 may as well be replaced by a number of shorter grooves to match the lugs.
- the mounting tool 40 is formed with a number of short ridge portions for producing such lugs.
