Abstract
The utility model relates to an auxiliary tool for dissembling a diesel engine main bearing cover. The auxiliary tool comprises a tool body consisting of a support plate, a main bearing cover support plate and a bolt support plate, wherein one side of the middle part of the main bearing cover support plate is connected with one end of the support plate; one side of the middle part of the bolt support plate is connected with the other end of the support plate; the main bearing cover support plate and the bolt support plate are both positioned on a side surface of the support plate; the length of the bolt support plate is one time greater than that of the main bearing cover support plate; U-shaped grooves are respectively formed in two sides of the other side of the bolt support plate; the distance between the two U-shaped grooves is the same as the distance between two bolt holes in the main bearing cover. When the auxiliary tool is used, the problems that the cleanness of the diesel engine is poor and the performance of the diesel engine is affected as a main cover bolt is stressed inside the bolt hole, the bottom of the bolt can damage an initial threaded section at the top part of the bolt hole and thread chippings are brought to a diesel engine main cover combining surface or an upper main shaft bushing mounting surface when the diesel engine main bearing cover is directly disassembled by using an iron hammer, are avoided.
Description
Technical field
The utility model relates to the aid for diesel engine main bearing cover dismounting.
Background technology
Main beating cap is the strength member that crankshaft of diesel engine runs well and power is exported.In the assembling process of crankshaft of diesel engine, need to dismantle lower main axis from cylinder body and hold lid, before dismounting, just main bonnet bolt be unclamped, main bonnet bolt not taken out; The mode of existing dismounting main beating cap is directly struck down with iron hammer, knock in process main bonnet bolt to the strong effect of bolt hole, be easy to damage main beating cap faying face bolt hole, the start screw threads tooth meat at bolt hole top is taken on the faying face of main beating cap, or take on main bearing shell installed surface, cause faying face or installed surface cleannes poor, bearing shell is easy to wear, affect service life, and then affect diesel engine performance.If main bonnet bolt is unclamped and takes out and tear again main beating cap open afterwards, pull down so main lid and again bolt is installed to above main beating cap afterwards, can affect productive temp like this.
Utility model content
In order to solve the dismounting of main beating cap in crankshaft of diesel engine assembling process, have above-mentioned problem, the utility model provides a kind of aid for diesel engine main bearing cover dismounting.
Aid for diesel engine main bearing cover dismounting comprises the tool body being comprised of gripper shoe, main beating cap supporting plate and bolt supporting plate; One side at main beating cap supporting plate middle part is connecting one end of gripper shoe, and a side at bolt supporting plate middle part is connecting the other end of gripper shoe, and main beating cap supporting plate and bolt supporting plate be a side of position gripper shoe all, and main beating cap supporting plate and bolt supporting plate are parallel to each other; The length of bolt supporting plate is the more than a times of main beating cap pallet length; The opposite side both sides of bolt supporting plate offer respectively U-lag, and the spacing between the U-lag of both sides is identical with the spacing between the bolt hole of both sides in main beating cap.
The length of described gripper shoe is 100～120 ㎜, and width is 20～25 ㎜; The length of described bolt supporting plate is 120～160 ㎜, and width is 15～20 ㎜; The length of main beating cap supporting plate is 50～60 ㎜, and width is 15～20 ㎜.
Useful technique effect of the present utility model is: when dismounting main beating cap, by the U-lag on bolt supporting plate, main bonnet bolt is lifted to bolt hole, and then knock main beating cap, pulled down.While having avoided directly removing with iron hammer, main bonnet bolt is stressed also in bolt hole time, and bolt bottom can damage the start screw threads section at bolt hole top, takes ridge meat to diesel oil owner and covers faying face or upper main bearing shell installed surface, cause its cleannes poor, affect diesel engine performance.The utility model is simple in structure, easy to use, cost is low.

The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
Referring to Fig. 1, the aid of dismantling for diesel engine main bearing cover comprises the tool body being comprised of gripper shoe 2, main beating cap supporting plate 3 and bolt supporting plate 1.One side at main beating cap supporting plate 3 middle parts is connecting one end of gripper shoe 2, one side at bolt supporting plate 1 middle part is connecting the other end of gripper shoe 2, one side of main beating cap supporting plate 3 and 1 equal gripper shoe of bolt supporting plate 2, sees Fig. 3, and main beating cap supporting plate 3 and bolt supporting plate 1 are parallel to each other.The length of bolt supporting plate 1 is the more than a times of main beating cap supporting plate 3 length, sees Fig. 2.The both sides of bolt supporting plate 1 opposite side offer respectively U-lag 4, and the spacing between both sides U-lag 4 is identical with the spacing between both sides bolt hole in main beating cap 5.
The length of gripper shoe 2 is 110 ㎜, and width is 22 ㎜; The length of bolt supporting plate 1 is 140 ㎜, and width is 18 ㎜; The length of main beating cap supporting plate 3 is 55 ㎜, and width is 18 ㎜.
Referring to Fig. 4, during use, first main beating cap supporting plate 3 is placed in to the below of main beating cap 5, first by the U-lag 4 on bolt supporting plate 1, main bonnet bolt 6 is upwards held up, when main beating cap supporting plate 3 is fitted with main beating cap 5 is inner, aid is in stress, and now the bolt hole of main beating cap 5 faying faces lifted from main bonnet bolt 6 by bolt supporting plate 1, and then knock main beating cap 5 sides with iron hammer, main beating cap 5 can be pulled down.
