Technical field
The present invention relates to a kind of auxiliary locator and method, particularly to one when flywheel shell of engine is installed, it is ensured that �� 174H7 hole and the auxiliary locator of the axiality in �� 43H7 hole in cylinder block and localization method on bell housing.
Background technology
Electromotor is as the kernel component of automobile, manufacture requirements its high-performance of height guarantee, high reliability. Hole K1(�� 174H7 on bell housing as shown in Figure 1 and Figure 2) with cylinder block on hole K2(�� 43H7), it is necessary to making �� 174H7 after bell housing and two parts of cylinder block have assembled is �� 0.05 to �� 43H7 ensuring coaxiality.
Existing assembly method is to position link pin X2 and be contained in cylinder block by a �� 12 is positioned a round pin X1 and �� 12, and the pitch-row L1 of two dowel holes is 230mm, and its line is in the horizontal direction. Hole K1, hole K2 are coaxial, and the upright opening in the two hole and link pin X2 hole, location is 315mm from L2, and the lateral aperture in the two hole and link pin X2 hole, location is 190mm from L3. With the two alignment pin location and installation bell housing, after bell housing installation, detect the �� 174H7 hole K1 axiality to �� 43H7 hole K2. Even if machining can guarantee that the �� 174H7 hole K1 axiality �� 0.05 to �� 43H7 hole K2, having arrived after assembling link ressembles bell housing as stated above, axiality also can be deteriorated, and can not meet the assembling of subsequent parts.
Existing mounting technology can not stably ensure that �� 174H7 hole K1 is qualified to the axiality �� 0.05 of �� 43H7 hole K2 after repeating assembling, main cause is as follows: after two alignment pins X1, X2 are contained in cylinder block 2 and the position relationship of �� 43H7 hole K2 be fixing, but two alignment pin distance �� 43H7 hole K2 are distant, owing to the hole, location on bell housing and two alignment pins are transition or matched in clearance.When repeating to assemble, the positioning precision of location hole and alignment pin on bell housing cannot ensure bell housing �� 174H7 hole K1 to the axiality of �� 43H7 hole K2 in cylinder block in the scope required.
Summary of the invention
The present invention is to overcome defect in above-mentioned prior art, by auxiliary locator and corresponding localization method, the axiality of respective coaxial bore K1 and the K2 of bell housing and cylinder block can be made up when assembling, be effectively reduced the problem that the positioning precision between bell housing and cylinder block is not enough.
For achieving the above object, the invention provides a kind of auxiliary locator, for auxiliary positioning the axiality ensureing the hole K1 on flywheel shell of engine and the hole K2 in cylinder block, this device includes: positioning sleeve, it has cannular boss, and cannular boss external diameter is suitable with the hole K2 in cylinder block; Positioning sleeve is fastened in cylinder block by the first bolt; Bell housing location bar, it is arranged in the hole K1 on bell housing, has bar portion and positioning boss, and bar portion is inserted in the hole of the cannular boss of positioning sleeve and positioning boss is connected to the outside of positioning sleeve; Bell housing location bar is fastened in cylinder head by the second bolt.
In technique scheme, the first bolt quantity can be two, and is M12 bolt; Second bolt quantity can be one, and is M10 bolt.
In technique scheme, the hole K1 on bell housing is �� 174H7; Hole K2 in cylinder block is �� 43H7.
For achieving the above object, present invention also offers a kind of assisted location method, for ensureing the axiality of the hole K1 on flywheel shell of engine and the hole K2 in cylinder block, the method comprises the steps: to be inserted in the hole K2 in cylinder block the cannular boss on positioning sleeve, and is fastened in cylinder block with the first bolt by positioning sleeve; Bell housing is positioned in the hole K1 that bar loads on bell housing, and make the bar portion of bell housing location bar be inserted in the hole of cannular boss, the positioning boss of bell housing location bar abuts against with the outside of positioning sleeve simultaneously, with the second bolt, bell housing is positioned bar and is fastened in cylinder head; Location round pin X1 and location link pin X2 is knocked in hole, corresponding location and realizes location; After fastening bell housing and cylinder block by technological requirement, dismounting bell housing location bar and positioning sleeve successively, thus completing the location assembling of bell housing.
Compared with prior art, there is advantages that
After applying this auxiliary locator assisted location method and assembling, it is qualified that the axiality of the hole K2 in cylinder block can stably be ensured by the hole K1 on bell housing.
