Abstract
The utility model relates to a hydraulic wheel-pulling machine, which is composed of an outer sleeve, a pump core, a front valve body, a back valve body, an oil cylinder, a piston, a release valve, a fuel injection valve, a protective valve, a front nut, and a back nut. The pump core can conduct the axial movement for oiling the cylinder and can be rotated for oiling the cylinder. The top end of the piston is provided with a top device and is convenient to the align the effect center of work pieces during operation. The outer part of the outer cover is provide with screw threads and can be directly fix a circular disc of which the middle is provided with the thread holes on the outer cover. The utility model has the characteristics of labor saving, balanced stress of the work piece, difficult damage, and flexible operation and can select the operation mode according to the operation position.
Description
The utility model relates to a kind of utensil that the wheel shape object is disassembled from axle, and specifically a kind of hydraulic pressure draws turbine.
At present, the turbine that draws of domestic use is mechanical, exists effort, workpiece discontinuity equalization, fragile workpiece and needs the defective of bigger operating position.
The purpose of this utility model be propose a kind of can be laborsaving, workpiece stress equalization, the hydraulic pressure that is difficult for defective work piece, flexible operation draw turbine.
The purpose of this utility model is finished in the following way: a kind of hydraulic pressure draws turbine; it comprises overcoat, the pump heart, rear valve body, front valve shell, oil cylinder, piston, fuel outlet valve, fuel feeding valve, protective valve, preceding nut and back nut, and fuel feeding valve and protective valve all are made up of spring and steel ball.Wherein, pump has a polygonized structure and a step in the heart, a screw-casing is arranged in the outside of this polygonized structure, one end of screw-casing is against step, there is helicitic texture the outside of screw-casing, the centre of screw-casing have one with the identical polygonal hole of this changeable shape structure size, the pump heart can be squeezed into hydraulic oil in the oil cylinder by fuel feeding valve along the hole axially-movable of screw-casing central polygonal, and piston is ejected.Also there is helicitic texture centre at rear valve body, matches with screw-casing, when the pump heart rotates, driving screw-casing rotates simultaneously, the screw thread rotation of screw-casing in the middle of the valve body forward, the step that the spiral casing pressure the pump heart moves the pump heart vertically, and hydraulic oil is squeezed in the oil cylinder by fuel feeding valve.A Finial device is arranged on the top of piston, and it is made up of center sleeve, top, spring and spring base, the center of effort position of alignment pieces when being convenient to operate, and this is top can withdraw when stressed.There is screw thread the outside of overcoat, and the circular discs that can directly the centre be threaded the hole is fixing on the coat, and the spacing of adjusting and workpiece.
Hydraulic pressure of the present utility model draws turbine owing to be hydraulic drive, there is the top of alignment pieces center of effort position on the top of piston, the pump heart both can axially-movable to oiling in the oil cylinder, also can rotate two kinds of modes of operation of oiling in the oil cylinder, therefore, have laborsaving, workpiece stress equalization, be difficult for the characteristics of defective work piece, flexible operation, and mode of operation is selected in the position can be according to operation the time.
