Abstract

The invention discloses a multi-station balanced pressing mechanism for a gas-liquid conversion cylinder. The multi-station balanced pressing mechanism can guarantee the balanced press force of all stations and comprises a cylinder. The cylinder is controlled by an electromagnetic valve to be ventilated or not. A first sealing pad is arranged in the cylinder and divides the cylinder into a left cavity and a right cavity. The right cavity is provided with a pipe cavity protruding outwards. A second sealing pad is arranged in the pipe cavity and used for separating the pipe cavity and an oil cavity of an oil cylinder. The right side of the oil cylinder is communicated with an oil chamber through a pipeline. Four piston cavities are arranged side by side at the lower portion of the oil chamber at equal intervals. Pistons capable of moving axially along the piston cavities are arranged in the piston cavities and provided with sealing rings for preventing hydraulic oil from seeping downwards. The lower ends of the pistons are connected with piston rods. The diameters of all the piston rods are the same. Reset springs are arranged on the peripheries of the piston rods. Pressing boards are arranged at the lower ends of the piston rods.

Description

The balanced hold-down mechanism of gas-liquid conversion cylinder multi-position
Technical field
The present invention relates to clamp technology, be specifically related to the balanced hold-down mechanism of a kind of gas-liquid conversion cylinder multi-position.
Background technique
Process a groove matched with key on axle or in hole, be used for fitting key, with transmitting torque, this groove is just keyway.With milling method processing keyway class workpiece, not only quality is good, and efficiency is high.Axle processes keyway, usually adopts keyway cutter keyseat, during processing keyway, coaxality and degree of symmetry are the key factors ensureing keyway quality of processing, therefore, seem very important to the clamping position of shaft-like workpiece.At present, in multi-position processing, the hold-down mechanism for axle class keyseat often cannot ensure the equilibrium of impacting force on each station, therefore cannot ensure that the keyway processed has unified quality, causes the quality of product of dispatching from the factory uneven.
Summary of the invention
The invention is intended to provide a kind of balanced hold-down mechanism of gas-liquid conversion cylinder multi-position that each station has balanced impacting force of guaranteeing.
The balanced hold-down mechanism of gas-liquid conversion cylinder multi-position in this programme, comprise cylinder, cylinder is by electromagnetic valve break-make gas, the first sealing gasket is provided with in cylinder, cylinder is divided into left chamber and right chamber by the first sealing gasket, right chamber has outwardly tube chamber, the second sealing gasket is provided with in tube chamber, second sealing gasket is for separating the oil pocket of tube chamber and oil cylinder, the right side of oil cylinder is communicated with a grease chamber by pipeline, the bottom of grease chamber is equally spaced is provided with four piston cavity side by side, being provided with in piston cavity can along the piston of piston cavity axial motion, piston is provided with the seal ring preventing the downward seepage of hydraulic oil, the lower end of piston connects piston rod, the diameter of each piston rod is identical, piston rod periphery is provided with Returnning spring, the lower end of piston rod is provided with pressing plate.
Cylinder in this programme, oil cylinder and grease chamber form gas-liquid conversion cylinder jointly.
Working principle and the beneficial effect of this programme are as follows:
When passing into gas in cylinder, the pressure of pressurized gas passes through gas-liquid conversion cylinder, become the oil pressure be multiplied, each piston is under the promotion of hydraulic oil, compress each workpiece by respective piston rod and pressing plate simultaneously, during the reverse air feed of solenoid valve, oil cylinder pressure release, piston rod resets under the effect of Returnning spring.
In this programme, because the diameter of each piston rod is identical, therefore can ensure that the impacting force suffered by each workpiece is identical, the equilibrium that can realize each workpiece compresses, and guarantees the conformity of workpiece keyway quality of processing.
Further, also comprise pedestal, pedestal top is provided with four stations for clamping work pieces, and each station all has V-shaped groove, and the notch of V-shaped groove is corresponding with press plate position.Jointly clamp shaft-like workpiece by V-shaped groove and pressing plate, the stability that shaft-like workpiece clamps can be guaranteed.
Further, the middle part of pressing plate has tapped blind hole, and the lower end of piston rod is provided with outside thread, and pressing plate is connected with piston rod thread.Pressing plate and piston rod are threaded connection, and when conveniently compressing the shaft-like workpiece of different size, change pressing plate.
Further, for sealing grease chamber further, preventing grease chamber's leakage of oil oil impregnate, being respectively equipped with the 3rd sealing gasket in the both sides of grease chamber.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
