Embodiment Construction

[0013] The present invention will be described in further detail below by means of specific embodiments:

[0014] The reference signs in the drawings of the description include: cylinder 1, first gasket 2, oil cylinder 3, pressure plate 4, piston rod 5, workpiece 6, V-shaped groove 7, pipeline 8, third gasket 9, return spring 10 , sealing ring 11, hydraulic oil 12, second gasket 13.

[0015] Taking keyway milling of shaft workpieces as an example, the implementation is basically as attached figure 1 As shown: the gas-liquid conversion cylinder multi-position balanced pressing mechanism in this embodiment includes a base, the base includes a lower workbench and side guide seats, and four workbenches for clamping workpieces are arranged on the upper part of the workbench. Each station has a V-shaped groove. There are four vertical guide grooves on the side of the guide seat.

[0016] In this embodiment, the cylinder, the oil cylinder and the oil chamber jointly constitute the...

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

technical field [0001] The invention relates to fixture technology, in particular to a multi-station balanced pressing mechanism of a gas-liquid conversion cylinder. Background technique [0002] A groove matching the key is machined on the shaft or in the hole to install the key and transmit torque. This groove is called a keyway. Processing keyway workpieces with milling method is not only of good quality, but also of high efficiency. The keyway is processed on the shaft, and the keyway is usually milled with a keyway milling cutter. The coaxiality and symmetry are the key factors to ensure the quality of the keyway when machining the keyway. Therefore, the clamping and positioning of the shaft workpiece is very important. At present, in multi-station machining, the pressing mechanism used for shaft milling key slots often cannot guarantee the balance of the pressing force on each station, so it cannot guarantee the uniform quality of the processed key slots, resulting in...
