Abstract
The invention discloses a wabbler cylinder head bolt which is characterized in that a wabbler is connected to the upper portion of a screw through a bearing cap. An annular recess is arranged at the bottom end of the bearing cap. A threaded rod part is disposed on the lower portion of the screw. An annular groove is arranged on the periphery of a connection of the threaded rod part and the screw. The wabbler cylinder head bolt is strict in size tolerance and surface quality requirements, and high in comprehensive mechanical performance requirements.
Description
Technical field
The present invention relates to a kind of bolt, is a kind of motor wabbler cylinder head bolt specifically.
Background technique
Motor is special with the cylinder head bolt structure, and its performance directly influences the quality of whole motor.Motor adopted external import in the past with cylinder head bolt, but external import has a lot of inconvenience: the one, and it is untimely to supply, and the 2nd, quality problems are difficult to be coordinated, and the 3rd, expensive etc.
Summary of the invention
Purpose of the present invention is that a kind of motor wabbler cylinder head bolt is provided.
To achieve these goals, the present invention is connected with plum blossom spiral shell head on the top of screw rod by supporting cap, is provided with loop concave at the bottom end face of supporting cap, and screw mandrel portion is located at the bottom of screw rod, and periphery is provided with annular groove in the joint of screw mandrel portion and screw rod.
By above setting, the present invention adopts the special steel manufacturing, and the external dimension at each position, geometrical shape require to make according to the use state, are installed in narrow position, and this special plum blossom conch shape is applicable to installation.Mechanical property of the present invention, surface quality are adapted to working environment, and the bolt cold-heading molding is conducive to guarantee material inside organization, through the heat treatment of shielding gas atmosphere mesh-belt furnace, carry out surface treatment at last.Tolerance of size of the present invention, surface quality are strict, and comprehensive mechanical performance requires high.
Description of drawings
Now the invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional view of supporting cap of the present invention.
Among the figure: 1, screw rod, 2, supporting cap, 3, plum blossom spiral shell head, 4, loop concave, 5, screw mandrel portion, 6, annular groove.
Embodiment
As shown in Figure 1, 2, the present invention is connected with plum blossom spiral shell head 3 on the top of screw rod 1 by supporting cap 2, bottom end face at supporting cap 2 is provided with loop concave 4, and screw mandrel portion 5 is located at the bottom of screw rod 1, is provided with annular groove 6 in the joint periphery of screw mandrel portion 5 and screw rod 1.By above setting, the present invention adopts the assembling of corner method, and unique texture and inherent technical order provide guarantee for the performance of whole motor, and the bottom end face of supporting cap 2 adopts the particular design of loop concave 4, under the effect of alternating force, be unlikely to loosening, can better play the locking effect.
