Abstract
The invention relates to an adjustment method for eliminating the fit tolerance of a workpiece, in particular to an adjustment method for eliminating the fit tolerance of the surface size of an aluminum model, which includes the steps: machining adjusting threaded holes on matching surfaces of a lower aluminum model and an upper aluminum model, assembling a Y-directional control bolt in the adjusting threaded holes and reserving a 0.5mm clearance; penetrating the upper aluminum model through a fixed threaded hole assembly through a fixing bolt; detecting the two matching surfaces, and adjusting the fit clearance between the two surfaces of the upper aluminum model and the lower aluminum model by rotating the Y-directional control bolt to reach a theoretical tolerance range; and screwing the fixing bolt to reach required torque so as to complete adjustment. The adjustment method for eliminating the fit tolerance of the surface size of the aluminum model can be used for effectively eliminating the tolerance of relative positions of contact matching surfaces of matching parts, and is wide in adaptability and simple in operation.
Description
Technical field
The present invention relates to a kind of elimination control method of workpiece fit tolerance, specifically is a kind of elimination control method of aluminum model element surface size fit tolerance.
Background technology
In machining process; Because factors such as part thermal deformation, machinery equipment precision and manually-operated; Tend to make two mating parts of separate machined on the surface engagement size, error to occur, therefore need to eliminate the relative position tolerance of counterpart contact matching face.
Summary of the invention
To the technical problem that exists in the prior art, the object of the present invention is to provide a kind of elimination control method of aluminum model element surface size fit tolerance of the relative position tolerance of eliminating counterpart contact matching face.
The technical scheme that the present invention adopts is following:
The elimination control method of aluminum model element surface size fit tolerance comprises epimere aluminum model, hypomere aluminum model, and the mating surface of said epimere aluminum model and hypomere aluminum model is " Z " shape, it is characterized in that, comprises the steps:
Mating surface place with epimere aluminum model on hypomere aluminum model processes the adjusting screwed hole in advance, Y is entered to the control bolts assemblies, and reserve the 0.5mm gap;
Pass retaining thread hole fit on to epimere aluminum model through set bolt;
At this moment detect two mating surfaces, through rotating Y to the control bolt, the fit clearance between adjustment epimere aluminum model and two faces of hypomere aluminum model makes it to reach in the theoretical margin of tolerance again;
Again set bolt is torqued-up to and requires moment, promptly accomplish adjustment.
Further, said set bolt and Y all are level to the control bolt and arrange, and are in the upper and lower position, and installation direction is opposite.
The elimination control method of aluminum model element surface size fit tolerance of the present invention can be good at eliminating the relative position tolerance of counterpart contact matching face, and adaptability is wider, and simple to operate.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that the present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is epimere aluminum model and hypomere aluminum structure of models sketch map.
Fig. 2 be among Fig. 1 A-A to view.
Fig. 3 is the partial enlarged drawing at B place among Fig. 2.
The specific embodiment
Shown in Fig. 1-3, the elimination control method of aluminum model element surface size fit tolerance comprises the steps:
" Z " shape mating surface place with epimere aluminum model 100 on hypomere aluminum model 101 processes the adjusting screwed hole in advance, Y is entered to 102 assemblings of control bolt, and reserve the 0.5mm gap.
Pass retaining thread hole fit on to epimere aluminum model 100 through set bolt 103.
At this moment detect two mating surfaces again, through rotating Y to control bolt 102, the fit clearance between adjustment epimere aluminum model 100 and 102 two faces of hypomere aluminum model makes it to reach in the theoretical margin of tolerance again.
Again set bolt 102 is torqued-up to and requires moment, promptly accomplish adjustment.
Arrange because set bolt 103 all is level with Y to control bolt 102, and be in the upper and lower position, installation direction is opposite, and the force direction of F1 and F2 is opposite, therefore adjusts set bolt 103, can't cause rotation, thereby reaches the effect of eliminating tolerance.
Above content only is to give an example and explanation to what the inventive method was done; Under the technical staff in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the structure of invention or surmount the defined scope of these claims, all fall into protection scope of the present invention.
Claims (2)
