Abstract
The invention relates to a positioning method for use in the machining of split bearing blocks, which is characterized by comprising: machining a blind hole on each of the combining faces of an upper bearing block and a lower bearing block, wherein the diameter dimensions of the blind holes are equal; machining cylindrical pins on machining equipment, wherein the diameter of the cylindrical pins is equal to the diameter of the blind holes; arranging the lower ends of the two cylindrical pins in the blind hole of the lower bearing bock respectively, wherein the cylindrical pins are in clearance fit with the blind holes; arranging the blind hole of the upper bearing seat on the cylindrical pins on the two sides of the lower bearing block, wherein the cylindrical pins in clearance fit with the blind hole on the lower surface of the upper bearing block; and after the positioning operation is finished, clamping the upper bearing block and the lower bearing block as a whole on the equipment for subsequent machining. In the positioning method, positioning is realized by the cylindrical pins, a special mounting mode is adopted, and thus, a positioning precision problem is solved and problems of difficult disassembly and assembly and the like are also solved; and the positioning method also has the advantages of simple structure, economy, practicality, small labor intensity and the like.
Description
Technical field
The invention belongs to the bearing block processing technique field, particularly a kind of split bearing block processing positioning method that is used for.
Background technology
In mechanical industry, bearing block is divided into two kinds of forms usually: a kind of is monoblock type, another kind is split type, because split type bearing block is more conducive to assembling, so along with the progress of working ability, split type bearing block has occupied body position gradually, but the processing of split type bearing block location is to hinder the obstacle that it continues development, the pin-and-hole of main at present employing up/down perforation positions, and needs special lengthening drill bit and reamer.Alignment pin or cross to win cooperate or matched in clearance cooperates if cross to win, and dismounting is difficulty very; If matched in clearance, the location inaccuracy.So demand not only accurately but also to be beneficial to the localization method of processing imperative.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of simple in structure, positioning accuracy is high, the location is reliable, economical and practical, labour intensity is little is used for split bearing block processing positioning method.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of split bearing block processing positioning method that is used for, it is characterized in that: described localization method is:
(1), at first on the mating surface to upper axis bearing and lower shaft bearing on the process equipment, processes a blind hole respectively; The diameter dimension of each blind hole and the grade of tolerance all equate;
(2), on process equipment the processing column pin, the diameter dimension of described straight pin equals the diameter of blind hole, the tolerance of Lower Half and blind hole do not wait on the straight pin;
(3), the Lower Half with two straight pins is installed in the blind hole of lower shaft bearing straight pin and blind hole interference fit respectively;
(4), the blind hole with the upper axis bearing is installed on the straight pin of lower shaft bearing both sides the blind hole employing matched in clearance of straight pin and top chock lower surface;
(5), finish above-mentioned positioning action after, upper axis bearing and lower shaft bearing are clipped in the processing of carrying out postorder on the equipment as an integral installation.
The present invention can also adopt following technical scheme:
The both ends of described straight pin all are rounded down.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, promptly realize the location by straight pin, and this straight pin lower end and lower shaft bearing blind hole interference fit, the upper end of straight pin and upper axis bearing blind hole matched in clearance, so not only solved the positioning accuracy problem, and having solved problems such as dismounting difficulty again, the present invention also has advantages such as simple in structure, economical and practical, that labour intensity is little in addition.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 to Fig. 4
A kind of split bearing block processing positioning method that is used for, this localization method is:
(1), at first on the process equipment respectively to the mating surface of upper axis bearing 1 and lower shaft bearing 2 on processing blind hole (1-1,2-1); The diameter dimension of each blind hole and the grade of tolerance equate that this tolerance is H7 in the present embodiment;
(2), on process equipment processing column pin 3, the diameter of described straight pin 2 equals the diameter of blind hole, the grade of tolerance of the halves up and down of straight pin does not wait, the tolerance of the straight pin first half is f6 in the present embodiment; The tolerance of blind hole Lower Half is m6; For the ease of assembling, the both ends of described straight pin 2 all are rounded down;
(3), the Lower Half with two straight pins is installed in the blind hole of lower shaft bearing respectively, straight pin 3 and blind hole 2-1 interference fit;
(4), the blind hole 1-1 with upper axis bearing 1 is installed on the straight pin 3 of its corresponding lower shaft bearing 2 both sides the blind hole 1-1 employing matched in clearance of straight pin 3 and top chock 1 lower surface;
(5), finish above-mentioned positioning action after, upper axis bearing 1 and lower shaft bearing 2 are clipped in the processing of carrying out postorder on the equipment as an integral installation.
Above-mentioned localization method, realize the location by straight pin, and adopt special mounting means, be straight pin lower end and lower shaft bearing blind hole interference fit, the upper end of straight pin and upper axis bearing blind hole matched in clearance, so not only solved the positioning accuracy problem, and solved problems such as dismounting difficulty again, the present invention also has advantages such as simple in structure, economical and practical, that labour intensity is little in addition.
