Problems solved by technology

[0004] Since the damping screw base is open to the outside to allow access to the screw head to screw it in / out, the problem with this damping system is ensuring that the screw cannot be pushed out by the pressurized fluid, especially when the screw is inserted into the base but not when screwed in
[0007] However, it is clear that in both cases additional machining must be done on the base or barrel after the screw has been inserted into the base or barrel

Embodiment Construction

[0018] Referring to the accompanying drawings, a damping device for a fluid pressure actuator, such as an air cylinder 100, is generally indicated at 1 .

[0019] The damping device 1 includes: a barrel 10 ; and a damping screw 12 inserted into the barrel 10 .

[0020] The cartridge 10 is adapted to be inserted into a cartridge base 14 formed in a cover 102 of the actuator. The barrel 10 extends about a barrel axis X between a proximal end 10' and a distal end 10". The proximal end 10' is defined by an end wall 16 (eg, substantially orthogonal to the barrel axis X) in which an end opening 16' is formed. The distal end 10 "Open to allow access to the damping screw 12.

[0021] The distal portion 18 of the barrel 10 has a cylindrical inner surface 20 and a conical outer surface 22 near the distal end 10″. At this conical outer surface 22, the thickness of the distal portion 18 of the barrel 10 is directed toward the open distal end. End 10" and increased.

[0022] The damping...

Abstract

A damping device for a fluid pressure actuator comprising: a barrel (10) adapted to be inserted into a barrel base (14); and a damping screw (12) inserted into said barrel. The distal portion (18) of the barrel has: a cylindrical inner surface (20) adapted to engage the head (120) of the damping screw (12) in a fluid-tight sealing manner; a conical outer surface ( 22), wherein the thickness of the distal portion of the cartridge increases towards the open distal end (10") such that when the cartridge (10) is inserted into the cartridge base (14), After the interaction between the side walls of the cartridge base (14) and the conical outer surface (22), the distal portion of the cartridge bends towards the cartridge axis (X), forming an undercut, The undercut prevents the damping screw (12) from exiting the barrel through the open distal end (10").

Description

technical field [0001] The present invention relates to a damping device for a fluid pressure actuator, such as a cylinder. Background technique [0002] Cylinders provided with a moving piston that reciprocates in the piston chamber are generally provided with a damping mechanism to ensure that the impact occurs when the piston at the end of the stroke reaches the front support formed in a specific seat in the cylinder head that closes the piston chamber strength is reduced. [0003] Known damping mechanisms include damping screws. A damping duct is formed in the cylinder head which fluidly connects the piston cavity with a cylinder head cavity formed in the cylinder head and is adapted to sealingly receive one end of the piston: when the piston is close to the end stroke position, the fluid compressed by the piston passes through A damping line flows into the cylinder head cavity, which damping or deceleration of the piston during the phase of the piston hitting the cyli...
