Technical field
The utility model relates to a kind of honing machine, especially relates to a kind of lower positioner of vertical honing machine.
Background technology
At present, the vertical honing machine that is used for the cylinder block honing, the location, lower end of cylinder block is all adopted sliding table usually, whole clamping process spended time is longer, inefficiency, and the sliding table complex structure, manufacturing cost is high, and the machining accuracy of cylinder block also is subjected to impact to a certain extent.Publication number is the lower positioner that the patent documentation of 202037533U discloses a kind of vertical honing machine, it adopts the structure that imports cover is set on locating flange, import cover and comprise coarse positioning circle and eccentric ring, the horizontal eccentric setting of eccentric ring, be welded with many importing bars between eccentric ring and coarse positioning circle, form the importing cover of toroidal.When reality was used, the lifting of the lower end of cylinder block entered and imports cover, then the cylinder block that tilts progressively is pushed into erectility, and the lower end of cylinder block is slipped in locating flange by importing cover, realizes the location of cylinder block lower end.Due to the horizontal eccentric setting of eccentric ring, give prominence to outside, and the length of cylinder block is longer, in the process of lifting, cylinder block very easily bumps with eccentric ring, causes the cylinder block lower end to damage, and, import cover and also can be damaged by collision, thus the service life of positioner under shortening.
The utility model content
The applicant is studied improvement for above-mentioned problem, and a kind of lower positioner of vertical honing machine is provided, simple in structure, low cost of manufacture imports the location efficient and convenient, reduce the collision in hoisting process, avoid the cylinder block lower end to damage, extend the service life of lower positioner.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of lower positioner of vertical honing machine comprises pedestal, and locating flange is fixedly mounted on described pedestal, imports cover and is fixedly mounted on locating flange, and described locating flange is provided with locating hole, and locating hole is provided with the importing chamfering; Described importing cover comprises coarse positioning circle and eccentric ring, and described eccentric ring is arranged on described coarse positioning circle top and is obliquely installed with respect to described coarse positioning circle bias, is welded with many importing bars between described eccentric ring and described coarse positioning circle.
Further:
Described eccentric ring is set with rubber sheath outward.
The angle of inclination of described eccentric ring is between 10 ° ~ 40 °.
The internal diameter of described eccentric ring is greater than the internal diameter of described coarse positioning circle.
The described importing bar outside is provided with and connects the reinforcement that imports the bar middle part.
Described pedestal comprises upper flange circle and lower flange circle, is welded with a plurality of vertical joint pins between upper flange circle and lower flange circle.
The inboard of described joint pin is provided with water fender.
Technique effect of the present utility model is:
The lower positioner of the disclosed a kind of vertical honing machine of the utility model, simple in structure, low cost of manufacture, import the location efficient and convenient, adopt the eccentric eccentric ring that is obliquely installed and rubber sheath is set, reduce the collision in hoisting process, avoid the cylinder block lower end to damage, extend the service life of lower positioner.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A place cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises pedestal 1, pedestal 1 is welded by upper flange circle 101, lower flange circle 102 and a plurality of joint pin 103, a plurality of joint pins 103 are vertically welded between upper flange circle 101 and lower flange circle 102, the quantity of joint pin 103 can be determined according to actual needs, the inboard of joint pin 103 is welded with water fender 104, and water fender 104 can prevent the outflow of honing cooling fluid and abrasive dust.Locating flange 2 is fixedly mounted on pedestal 1 by screw 4, importing cover 3 is fixedly mounted on locating flange 2 by screw 6, locating flange 2 is provided with locating hole 201, locating hole 201 is provided with and imports chamfering 202, add man-hour carrying out honing, the lower end of cylinder block is positioned in locating hole 201 on locating flange 2.import cover 3 and comprise coarse positioning circle 301 and eccentric ring 302, eccentric ring 302 is arranged on coarse positioning circle 301 tops, and eccentric ring 302 is eccentric and be obliquely installed with respect to coarse positioning circle 301, the angle of inclination B of eccentric ring 302 is usually between 10 ° ~ 40 °, in the present embodiment, the angle of inclination B of eccentric ring 302 is 15 °, be welded with many importing bars 303 between eccentric ring 302 and coarse positioning circle 301, the quantity that imports bar 303 can be determined according to actual needs, usually the internal diameter of eccentric ring 302 is greater than the internal diameter of coarse positioning circle 301, eccentric ring 302 and many importing bars 303 consist of the importing cover of an amesiality toroidal, the lifting of convenient cylinder block imports, and, because eccentric ring 302 is obliquely installed, when cylinder block lifts, the lower end of cylinder block is difficult for colliding eccentric ring 302.Import bar 303 outsides and be provided with and connect the reinforcement 304 that imports bar 303 middle parts, reinforcement 304 is welded on ringwise and imports bar 303 outsides, strengthens the intensity that imports cover 3.
The utility model is arranged on the lathe bed base of vertical honing machine by screw 5, during the lifting cylinder block, the cylinder block lower end can enter the horn mouth of the inclination that imports cover 3 easily, then the cylinder block that tilts progressively is pushed into erectility, the lower end of cylinder block is slipped into coarse positioning circle 301 and is imported to chamfering 202 by importing cover 3, and finally be positioned in locating hole 201 on locating flange 2, behind the upper end of upper positioner location and clamping cylinder cylinder body, can begin honing processing, the importing of cylinder block, location, convenient mounting and clamping are quick.In addition, in the present embodiment, the outer rubber sheath 7 that is set with of eccentric ring 302; even during the lifting cylinder block, the lower end collides eccentric ring 302; rubber sheath 7 plays protection and cushioning effect, has both avoided the cylinder block lower end to damage, and can extend again the service life of lower positioner.
