Abstract

The utility model relates to a rotary mould self-locking device which belongs to the technical field of a digital controlled rotary tower punching machine and is characterized in that an upper self-locking device and a lower self-locking device are respectively composed of an upper clamp splice, a lower clamp splice and a cylinder of which one side is fixed on a machine body by a bracket, wherein one end of each upper clamp splice is hinged with one end of each lower clamp splice, the ends opposite to the hinged ends of the upper clamp splice and the lower clamp splice of the upper self-locking device are connected by a spring, and the ends opposite to the hinged ends of the upper clamp splice and the lower clamp splice of the lower self-locking device are connected with a lower rotary table by a push rod sleeved with a spring. The utility model has simple structure, and the self-locking device upper and the lower self-locking device are respectively fixed on an upper rotary table and the lower rotary table of the digital controlled rotary tower punching machine. Under the situation of not using the rotary mould, a rotary shaft of the rotary mould is enclasped by using spring force to prevent rotation; when the rotary mould is used, the cylinders act to open the locking device, and the rotary shaft is driven by a motor to rotate freely. The utility model is favorable for prolonging the service life of the mould and enhancing punching quality, and has the advantages of convenient installation and maintenance, strong practicability and obvious economic benefit.

Description

Rotary Mould Self-locking Device

Technical field

The utility model relates to a kind of Rotary Mould Self-locking Device, is a kind of fixture of rotary die on the NC turret punch machine, belongs to the NC turret punch machine technical field.

Background technology

On NC turret punch machine, 1～2 rotary die all is housed usually, this mould carries out transmission by worm and gear, owing to be subjected to structural limitations, in design, worm and gear can not self-locking, cause rotary die in the process of punch process, owing to be subjected to the vibration influence of impulsive force, can rotate the problem that mould is controlled oneself and rotated once in a while, mould is asynchronous about causing.Cause the damage of mould or the decline of punching quality during punching.

Summary of the invention

The purpose of this utility model is to carry out transmission at rotary die on the existing NC turret punch machine by worm and gear that can not self-locking, thereby under the vibration influence of impulsive force, can rotate mould oneself rotates, bring the damage of mould or the deficiency that punching quality descends thus, a kind of Rotary Mould Self-locking Device simple in structure, reliable in action is provided.

The purpose of this utility model is achieved through the following technical solutions, a kind of Rotary Mould Self-locking Device, it is characterized in that described device comprises self-locking, following self-locking device, up and down self-locking device by the hinged fixture block up and down of an end and separately a side constitute through the cylinder that support is fixed on the fuselage, the corresponding end of the hinged end of fixture block up and down of last self-locking device connects through spring, and the push rod of corresponding end through being with spring of the last fixture block hinged end of following self-locking device is connected with lower rotary table.

The utility model is simple in structure, and in use, upper and lower self-locking device is separately fixed on the upper and lower rotating disk of NC turret punch machine, under the situation of not using this rotary die, utilizes spring force that the power transmission shaft of rotary die is held tightly, prevents to rotate.When needs used rotary die, locking device was opened in the cylinder action, power transmission shaft is free to rotate under the drive of motor, and the utility model helps prolonging the service life of mould, improves punching quality, install convenient for installation and maintenancely, have very strong practicality and remarkable economic efficiency.
