Description
Technical field
The utility model relates to engine assembly accessory technical field, particularly relates to the accessory that in a kind of engine assembly process, anti-tappet comes off.
Background technology
In engine assembly process, tappet assembles prior to camshaft, and in assembling process during engine upset, owing to lacking the support of camshaft, tappet can be deviate from from tappet hole, and obscission occurs.In order to avoid the problems referred to above, generally can use easy slip-off preventing accessory, avoid tappet to come off.Slip-off preventing accessory of the prior art, is generally simple column structure, directly inserts the camshaft that comes off and installs in emptying aperture, substitute camshaft plays support effect to tappet.In order to prevent accessory from dropping out from hole, the accessory of general design column structure and camshaft installing hole interference fit.But this mode inconvenient operation, the easily wearing and tearing and accessory is squeezed, after wearing and tearing, size diminishes, and still can come off.
Therefore, those skilled in the art need to improve assistant tool structure, to solve the above-mentioned problems in the prior art.
Utility model content
The purpose of this utility model is to provide the accessory that in a kind of engine assembly process, anti-tappet comes off, easy to use, and effectively can avoid existing in use procedure the danger that accessory comes off.
To achieve these goals, the utility model provides following technical scheme:
The accessory that in a kind of engine assembly process, anti-tappet comes off, comprise shutoff bar, shutoff club head and locking member, described shutoff bar and camshaft installing hole matched in clearance, described shutoff club head abuts with cylinder body lateral wall, and described shutoff club head is provided with locking member installing hole, described locking member is fixed through described locking member installing hole and cylinder body.
Preferably, described locking member comprises wing nut and studs.
Preferably, the end of thread that described studs is connected with described wing nut and described locking member installing hole matched in clearance, and the diameter of the end of thread be connected with cylinder body is greater than the diameter of described locking member installing hole.
Preferably, described shutoff bar is provided with organizes annular protrusion more, and described annular protrusion abuts with the inwall of described camshaft installing hole.
Preferably, described annular protrusion is three groups, and annular protrusion described in three groups is separately positioned on the head end of described shutoff bar, tail end and center position.
Preferably, described shutoff bar and described shutoff club head are formed in one structure.
The beneficial effects of the utility model are:
The accessory that in engine assembly process in the utility model embodiment, anti-tappet comes off, will be designed to and camshaft installing hole matched in clearance the passive shutoff bar of tappet, and facilitate the use of shutoff bar, avoid shutoff bar to wear and tear; In addition, add shutoff club head and locking member structure, accessory is fixed on cylinder body, stopped accessory and come off.
