The bolt penetrates through the middle position of the cross beam and is in threaded connection with the cross beam, and the bolt is arranged between the two vertical plates. The bottom plate is arranged below the bolt. The utility model has the characteristics of small, practical reliable, the commonality is good, and its application scope is wider, can satisfy the dismantlement demand of different model valve disk seats through the distance of adjusting both sides nipper.
Description
Technical Field
The utility model belongs to engine manufacturing equipment field, concretely relates to frock is dismantled to diesel engine valve disk seat.
Background
The valve seat is a circular surface machined into the cylinder block or cylinder head and the valve cone seals or seats against the valve seat. The valve seat usually adopts an embedded structure, and is pressed and mounted to the cylinder cover after being cooled by liquid nitrogen, so that interference fit is realized.
In the use process of the valve seat, due to repeated collision and abrasion of the valve and the valve seat, the surface sealing is not tight, and the valve seat needs to be replaced periodically. And the interference fit mode that adopts between disk seat and the cylinder head causes the degree of difficulty of dismantling objectively, under the circumstances of not damaging the cylinder head, the simple and easy practical dismantlement frock of design is so that the maintenance of valve disk seat.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: overcome prior art's not enough, provide a frock is dismantled to diesel engine valve disk seat, the utility model has the characteristics of small, practical reliable, the commonality is good, its application scope is wider, can satisfy the dismantlement demand of different model valve disk seats through the distance of adjusting both sides nipper.
The utility model provides a technical scheme that the problem that its exists adopted is:
a tool for disassembling a valve seat of a diesel engine valve comprises a cross beam, a vertical plate, a bolt and a bottom plate.
The two vertical plates are arranged on the cross beam in a sliding mode, and the end faces of the outer sides of the vertical plates are convexly provided with the grabbing plates.
The bolt penetrates through the middle position of the cross beam and is in threaded connection with the cross beam, and the bolt is arranged between the two vertical plates.
The bottom plate is arranged below the bolt.
Preferably, the top surface of the vertical plate is provided with a positioning screw in threaded connection with the vertical plate, and the vertical plate can be fixed on the cross beam by screwing the positioning screw.
Preferably, the upper end face of the bolt is provided with a hexagonal head, and the bolt can be rotated by rotating the hexagonal head.
Preferably, a handle is arranged on the bolt in a penetrating mode and located above the cross beam.
Compared with the prior art, the utility model discloses beneficial effect who has:
(1) the valve seat dismounting device is small in size, convenient to carry and particularly suitable for dismounting the valve seat outside a factory.
(2) The distance between the two grabbing plates is adjustable, and the disassembling requirements of valve seats of different types of valves can be met.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is the utility model relates to a frock appearance is dismantled to diesel engine valve disk seat.
In the figure, 1-beam, 2-vertical plate, 201-grasping plate, 3-positioning screw, 4-bolt, 5-bottom plate and 6-handle.
Detailed Description
The attached drawings are the best embodiments of the tool for disassembling the valve seat of the diesel engine, and the invention is further described in detail with reference to the attached drawings.
Shown in the attached drawing 1, the diesel engine valve seat dismounting tool comprises a cross beam 1, a vertical plate 2, a bolt 4 and a bottom plate 5.
Two perpendicular board 2 slide and set up on crossbeam 1, 2 outside terminal surfaces of perpendicular board are equipped with the board 201 of grabbing protrudingly, grab board 201 and lie in 2 downside ends of perpendicular board. The top surface of the vertical plate 2 is provided with a positioning screw 3 in threaded connection with the vertical plate, the positioning screw 3 is screwed, and the vertical plate 2 can be fixed on the cross beam 1.
A vertically arranged bolt 4 penetrates through the middle position of the cross beam 1 and is in threaded connection with the cross beam 1, and the bolt 4 is arranged between the two vertical plates 2. In order to rotate the bolt 4 conveniently, the upper end face of the bolt 4 is provided with a hexagonal head, and the bolt 4 can be rotated by rotating the hexagonal head. Or a handle 6 is arranged on the bolt 4 in a penetrating way, the handle 6 is positioned above the cross beam 1, and the bolt 4 is rotated by rotating the handle 6.
The bottom plate 5 is arranged below the bolt 4, and the bottom plate 5 is rotatably connected with the bolt 4, namely the bottom plate 5 can only rotate around the axis of the bolt 4.
The seat plate 5 is horizontally placed on the lower plane of the cylinder cover, the positioning screws 3 are loosened, the distance between the two grabbing plates 201 on the two sides is adjusted, the two grabbing plates 201 pass through inner holes of the valve seat and slide along the cross beam 1, the grabbing plates 201 can be positioned on the inner end face of the valve seat, and then the positioning screws 3 are fastened. The handle 6 is turned clockwise by both hands to enable the bolt 4 to generate acting force, so that the cylinder cover is detached from the valve seat, and the valve seat is detached.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge of those skilled in the art.
