Abstract
The utility model relates to a cylinder used for an electric riveter. A cylinder body (1) is provided with an upper cover (4), wherein the cylinder is fixed to the upper cover through a screw to form a sealing cavity; a piston rod (2) is arranged in the cavity and is penetrated through the upper cover (4) and the cylinder body (1); a working cavity for moving the piston rod (3) from top to bottom is arranged in the upper cover (4), the diameter of the working cavity (A) is larger than the diameter of the partial piston rod (3) which is penetrated through the upper cover, and the working cavity and the piston rod on the lower part of the working cavity form clearance fit; the lateral face of the upper cover (1) is provided with a ventilation hole (5) which is connected to the outer side and is communicated with the working cavity (A) in the upper cover (4). The utility model discloses the cylinder used for an electric riveter, which uses the working cavity for moving the piston rod from top to bottom to pressurize the rivets when the rivets are electrified and heated, and as a result, the condition that springs pressurize the rivets in the prior art can be altered to make different rivets adjust to different pressure and the machining quality of the rivets can be enhanced.
Description
Affiliated technical field
The utility model belongs to the bearing special equipment---the electric riveting machine technical field, relate generally to a kind of electric riveting machine cylinder, and it is to be used for to the retainer rivet energising of bearing and compressing of compression moulding.
Background technology
The riveted of medium-and-large-sized entity retainer bearing cage rivet is all finished on electric riveting machine.The course of work of electric riveting machine is: the forming surface of retainer rivet on the bearing is placed on the low punch, upper punch is placed on the cylinder piston rod, upper punch is pressed in the not forming ends of rivet earlier with smaller strength, energising heating then, behind to be heated the finishing, use bigger strength rivet compression moulding again, then, upper punch is driven by cylinder and returns.Twice pressurization of upper punch and return all and finish by cylinder.Electric riveting machine cylinder in the past, a compression spring is finished on when energising, added little pressure was by cylinder, and its is difficult to realize adjustment of pressure.Because therefore the needed pressure difference of big or small rivet can not get guaranteeing with regard to the quality that makes rivet.
Summary of the invention
The purpose of this utility model proposes a kind of electric riveting machine cylinder, makes its pressure that can adjust cylinder when rivet energising heating, to improve the riveted quality of electric riveting machine.
For achieving the above object, the technical scheme that the utility model is taked is: have cylinder body, cylinder body is provided with loam cake, the two is fixed together by screw, and form an airtight cavity, and in cavity, being provided with piston, this piston is positioned at the cavity middle part, piston is fixed on the piston rod by nut, and piston rod passes loam cake and cylinder body; Have one in the loam cake and be used to working chamber that piston rod is moved up and down, the diameter of this working chamber is greater than the diameter that passes the upper cover part piston rod, and form matched in clearance with the piston rod of its underpart, be provided with in the side of loam cake and the outside passage that is connected, the interior working chamber of this passage and loam cake communicates.
The electric riveting machine cylinder that the utility model proposes is when rivet energising heating, use the working chamber that is used to piston rod is moved up and down in the loam cake to pressurize to rivet, thereby changed and used the situation of spring in the past to the rivet pressurization, make different rivets be adjusted to different pressure, improved the crudy of rivet.
