Abstract
The utility model relates a valve seat ring removing device, which comprises a bearing frame, wherein a center threaded rod is arranged in a central hole formed in the middle of the bearing frame, the periphery of the middle of the center threaded rod is sheathed with an external thread sleeve pipe, the lower end part of the center threaded rod is movably hinged with a triangular top block, a connecting plate is arranged under the bearing frame, and both sides of the connecting plate are respectively hinged with an outward pull hook. The valve seat ring removing device is placed on the surface of a cylinder cover, a movable screw nut is rotated, hook points of the outward pull hooks point to connecting parts under a ring, then, the outer thread sleeve pipe and the center threaded rod are rotated, the triangular top block downwards slides, the outward pull hooks are transversely extruded, and the point parts of the outward pull hooks are forced to enter the joint part of the seat ring. Therefore, the seat ring can upwards move, and then, the movable screw nut is rotated to remove the seat ring. The valve seat ring removing device has the advantages of wide application range and uniform stress and is easy to pull out and flexible to operate.
Description
Technical field
The utility model belongs to the repair of machine technical field of tools, relates to a kind of porthole seat ring extractor of the porthole seat ring place under repair that the cylinder of internal combustion engine that damages is covered.
Background technology
To the porthole seat ring place under repair that the cylinder of internal combustion engine that damages covers, be the difficult point of mechanic's headache, because seat ring is in the porthole cover for seat that is stuck on the cylinder cover, be a small blind hole, beat and prizing not; At present, when repairing, be that whole cylinder cover is loaded onto lathe in regular large-scale repair shop, with lathe tool seat ring is wiped off, and then loaded onto new circle, much do not have the repair shop of condition all to adopt and act rashly, chisel out with chisel, in this way, most can ruining cover for seat, make the seat ring can not be fastening with cover for seat, often on-streamly make seat ring fall down cylinder interior,, the piston top is worn the porthole bending, cylinder sleeve is battered down, damage bigger.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of porthole seat ring extractor that the scope of application is big, stressed evenly, pull out easy and flexible operation advantage that has.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of porthole seat ring extractor, comprise bearing support, in the centre bore at the middle part of bearing support, center bolt is housed, silk braid pipe outside the periphery at center bolt middle part is set with, movable hinge joint has the triangle jacking block in the bottom of center bolt, yoke plate is housed below bearing support, has linked export-oriented drag hook respectively in the both sides of yoke plate.
Described bearing support is a bow-shaped structural.
Traveling nut is housed passing on the outer silk braid pipe that bearing support upper end exposes.
The upper end of described center bolt is provided with handle.
Described triangle jacking block is positioned at the centre of the export-oriented drag hook in both sides.
Described export-oriented drag hook links the both sides at yoke plate symmetrically.
Outer silk braid pipe pass the bearing support centre bore and be fixed on the yoke plate wire master hole around.
The beneficial effects of the utility model are: the utility model is placed on cylinder lid surface, rotate traveling nut, make the bill of export-oriented drag hook aim at joint under the circle, rotate outer silk braid pipe and center bolt then, three usefulness jacking blocks are glided, laterally the export-oriented drag hook of extruding forces export-oriented drag hook tip to enter the joint of seat ring.At this moment seat ring will on move, rotate traveling nut again, seat ring is removed; Has the advantage that the scope of application is big, stressed evenly, pull out easy and flexible operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-bearing support, the outer silk braid pipe of 2-, 3-center bolt, 4-yoke plate, the export-oriented drag hook of 5-, 6-traveling nut, 7-triangle jacking block, 8-handle.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of porthole seat ring extractor comprises bearing support 1, and this bearing support 1 is a bow-shaped structural,
In the centre bore at the middle part of bearing support 1, center bolt 3 is housed, silk braid pipe 2 outside the periphery at center bolt 3 middle parts is set with, the wire master hole at yoke plate 4 centers is passed in the bottom of described center bolt 3; Traveling nut 6 is housed passing on the outer silk braid pipe 2 that exposes bearing support 1 upper end, movable hinge joint has triangle jacking block 7 in the bottom of center bolt 3, and yoke plate 4 is housed below bearing support 1, has linked export-oriented drag hook 5 respectively in the both sides of yoke plate 4.
The upper end of described center bolt 3 is provided with handle 8; Described triangle jacking block 7 is positioned at the centre of the export-oriented drag hook 5 in both sides; Described export-oriented drag hook 5 links the both sides at yoke plate 4 symmetrically; Outer silk braid pipe 2 pass bearing support 1 centre bore and be fixed on yoke plate 4 wire master holes around.
Using method of the present utility model is: the utility model is placed on cylinder lid surface, rotate traveling nut, make the bill of export-oriented drag hook aim at joint under the circle, rotate outer silk braid pipe and center bolt then, three usefulness jacking blocks are glided, laterally the export-oriented drag hook of extruding forces export-oriented drag hook tip to enter the joint of seat ring.At this moment seat ring will on move, rotate traveling nut again, seat ring is removed; Has the advantage that the scope of application is big, stressed evenly, pull out easy and flexible operation.
