Abstract
A rapid dismounting apparatus for a piston cylinder sleeve comprises a nut, fixed pressure plate, a screw, a stud and a movable pressure plate, wherein one end of the screw is connected on the center point of the fixed pressure plate through a nut, the other end of the screw is hinged on the movable pressure plate, three troughs are evenly arranged on the fixed pressure plate along the radial direction, the stud is slightly longer than a cylinder sleeve, the diameter of the fixed pressure plate corresponds to the external diameter of a piston cylinder body, and the diameter of the movable pressure plate is slightly smaller than the external diameter of the piston cylinder sleeve. The rapid dismounting apparatus is simple in structure, easy for manufacture, low in cost, and convenient for use and operation. Compared with a conventional extractor, the rapid dismounting apparatus is rapid and convenient for dismounting, and labor saving and time saving in installation and dismounting. The rapid dismounting apparatus has centering property, and can realize automatic positioning of the apparatus. The movable pressure plate is hinged with the screw, which minimizes the inconvenience of conventional extractor in installing and centering a lower pressure plate and a screw, shortens installation and dismounting time, and reduces labor intensity of operators.
Description
Technical field
The utility model relates to a kind of instrument that the machine-building repairing trades are used in the installation or removal process of internal combustion engine cylinder sleeve.
Background technology
For a long time; Three-jaw, four paws or presser type extractor are continued to use in the dismounting of internal combustion engine cover always on the mine railway, when extractor is installed, need be placed on the pressing plate of extractor one end of piston bush, penetrate screw rod again; Can carry out then, make the comparatively inconvenience of disassemble and assemble work of piston bush.
Summary of the invention
The purpose of the utility model is: designs a kind of railway internal combustion engine cylinder sleeve rapid dismounting apparatus, the internal combustion engine cylinder sleeve is easy for installation and removal in maintenance process, and simple in structure, be convenient to make.
Realize that the technical scheme that the utility model purpose is taked is: it is made up of nut, fixation clip, screw rod, double-screw bolt, movable pressing board, and screw rod one end is connected with nut on the center of circle of fixation clip, and the other end is hinged on the movable pressing board; On fixation clip, radially evenly have three draw-in grooves; Double-screw bolt is longer than cylinder sleeve length slightly; Fixation clip diameter and piston/cylinder external diameter adapt, and the movable pressing board diameter is slightly less than the external diameter of piston-cylinder.
Movable pressing board is a circular slab, and diameter is slightly less than the piston-cylinder external diameter.
Movable pressing board is a long shaped plate, and two ends have radian, and its radian is identical with piston-cylinder end radian, and length is slightly less than the piston-cylinder external diameter.
The good effect of the utility model is: compare with traditional extractor, have dismounting effect quickly and easily; During installation, movable pressing board has been revolved parallel with screw rod, inserted and to treat the Device for pressing cylinder liner bottom, made movable pressing board vertical with cylinder sleeve then, and be adjacent in the cylinder sleeve end, rotating nut can be pressed into cylinder body with cylinder sleeve; During dismounting, three double-screw bolts slightly longer than cylinder sleeve are installed on the cylinder bolt hole of cylinder body, a nut is respectively installed in the double-screw bolt upper end, is stuck in three stud notch of fixation clip on the double-screw bolt, and movable pressing board aligns with cylinder sleeve, and the rotation nut is extracted cylinder sleeve; This device has automatic centering property, automatic location that can implement device.Movable pressing board and screw rod are hinged, have reduced the inconvenience that common extractor bottom pressing plate and screw rod are installed contraposition, have shortened the installing/dismounting time, have alleviated labor intensity of operating personnel.
Description of drawings
The specific embodiment
The utility model is shown in accompanying drawing 1; This device is made up of the double-screw bolt 4 of nut 1, three band nuts, fixation clip 2, movable pressing board 8, a dextrorotation double end trapezoid thread screw 5 and unit's pin 7; The length of double-screw bolt 4 of three band nuts than the long 50mm of cylinder sleeve about; The diameter of thread and cylinder bolt diameter are mainly used in when extracting cylinder sleeve and use together; Fixation clip 2 use thickness are that the low alloy steel plate of 18～20mm is processed, and diameter and cylinder body external diameter are basic identical, and fixation clip 2 radially has three draw-in grooves that are uniformly distributed with 3, are pressed into the position in order to realize the quick location and the observation cylinder sleeve of this device on piston body; Movable pressing board 8 is long shaped plates, and two ends have radian, and its radian is identical with piston-cylinder end radian; Length is slightly less than the piston-cylinder external diameter; Use thickness is that the low alloy steel plate of 18～20mm is processed, and the center is welded with the ears that are drilled with ￠ 16mm hole, in order to hinged with the circular hole of screw rod 5 lower ends.
When being pressed into the cylinder sleeve operation,, movable pressing board 8 has been revolved parallel with screw rod 5 like accompanying drawing 2,3, shown in 4; Device for pressing cylinder liner 10 bottoms are treated in insertion; Then movable pressing board 8 is set level vertically with cylinder sleeve 10, and be adjacent in end, cylinder sleeve 10 lower end, rotation nut 1 can be pressed into cylinder sleeve 10 in the cylinder body 9; When extracting the cylinder sleeve operation, like accompanying drawing 5,6, shown in 7, three double-screw bolts 4 are spun on the cylinder bolt hole of cylinder body 9, a nut is respectively installed in double-screw bolt 4 upper ends, is stuck in three draw-in grooves 3 on the fixation clip 2 on the double-screw bolt 4; Movable pressing board 8 inserted treat Device for pressing cylinder liner 10 bottoms, then movable pressing board 8 is set level vertically with cylinder sleeve 10, and be adjacent in end, cylinder sleeve 10 lower end, rotation nut 1 can be extracted cylinder sleeve 10.
