Description
Technical Field
The utility model relates to a press technical field especially relates to a be applied to nut locking device of press die cushion.
Background
The press (including a punch press and a hydraulic press) is a universal press with an exquisite structure. The press machine has the characteristics of wide application, high production efficiency and the like, and can be widely applied to processes of cutting, punching, blanking, bending, riveting, forming and the like. The metal is processed into parts by applying a strong pressure to the metal blank to cause plastic deformation and fracture of the metal. When the mechanical press works, a motor drives a large belt pulley (usually used as a flywheel) through a triangle belt, and a crank-slider mechanism is driven through a gear pair and a clutch, so that a slider and a male die move down linearly.
When the press die cushion is used, the existing driving shaft is only locked with the press die cushion through the nut in threaded connection, and due to the fact that vibration is large, the driving shaft and the nut can be frequently loosened (namely, the position of the fixed locking position can be frequently loosened).
Disclosure of Invention
The utility model aims to solve the technical problem that a be applied to nut locking device of press die cushion is provided, the lateral wall of interior gland and the toper through-hole cooperation extrusion of outer gland can eliminate the screw fit clearance of drive shaft and nut department after the screw is taut to reach locking effect.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a be applied to nut locking device of press die cushion, includes outer gland, interior gland and the drive shaft that links to each other with the press die cushion, drive shaft upper portion threaded connection have the nut, the upper end coaxial coupling of this drive shaft has the interior gland that is round platform form, the diameter of interior gland upper end be less than the diameter of interior gland lower extreme, this interior gland overcoat has outer gland, outer gland pass through the screw and link to each other with the nut upper end, be provided with the toper through-hole that matches with interior gland shape in this outer gland.
As a supplement to the technical scheme of the utility model, the upper end face of interior gland and drive shaft between pass through the screw fixation.
As a supplement to the technical solution of the present invention, the inner pressing cover is uniformly provided with four screws connected to the upper end surface of the driving shaft around the circumference.
As a supplement to the technical solution of the present invention, the outer gland is surrounded by four screws connected to the upper end of the nut.
As a supplement to the technical solution of the present invention, the outer press cover is in a ring shape.
Has the advantages that: the utility model relates to a be applied to nut locking device of press die cushion, drive shaft upper portion and nut threaded connection, interior gland pass through the screw fixed with the drive shaft upper end, outside the gland including the outer gland cover, the outer gland passes through the screw and links to each other with the nut, and the lateral wall of interior gland extrudees with the toper through-hole cooperation of outer gland, can eliminate the screw fit clearance of drive shaft and nut department after the screw is taut to reach locking effect. The utility model also has the advantages of simple structure, convenient use, low manufacturing cost, etc.
