Description
Technical Field
The utility model belongs to the technical field of mechanical tool, specifically be a piston engine valve spring lid and locking plate quick assembly disassembly instrument.
Background
The engine is an important part on surface mining equipment, but the valve spring cover and the locking plate of the engine are difficult to disassemble and assemble in the maintenance process. Traditional dismantlement valve spring lid and locking plate adopt the mode of violence dismantlement usually, the spring lid is pushed down to hollow stick one end promptly, strike the hollow stick other end with the hammer again, under the impact force, the locking plate drops, the valve spring lid that relies on the locking plate to fix drops thereupon, the mounting method is that two people's complex modes are installed, one of them person is with behind one side grooved hollow plug screw down valve spring, another people is quick with valve spring upper gasket and collet installation back in place, loosen the plug, make valve spring reset, compress tightly spring upper gasket and collet. The existing tool is difficult to disassemble, wastes time and labor, has low working efficiency and even possibly damages the valve spring cover and the locking plate.
SUMMERY OF THE UTILITY MODEL
The problem to prior art exists, the utility model provides a piston engine valve spring lid and locking plate quick assembly disassembly instrument, can realize one-man operation, the practical engine of many specifications engine, satisfy the spring lid of different model engines and locking plate dismouting demand, ensure that engine maintenance work high efficiency impels.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a piston engine valve spring lid and locking plate quick assembly disassembly instrument, includes support frame, adjustable support frame a, locating pin, adjustable support frame b, reset spring, ejector pin, presses handle, side opening, the support frame includes vertical pole and transverse bar, and the support frame is provided with the movable adjusting locating hole, installs adjustable support frame a through the locating pin on the vertical pole, is provided with the side opening that is used for the locking plate dismouting on the adjustable support frame a, is provided with adjustable support frame b on the support frame transverse bar, and adjustable support frame b bottom is provided with reset spring, and the ejector pin is connected to the reset spring bottom, and the ejector pin passes through the locating hole of support frame and presses the handle to be connected, presses the other end to connect on adjustable support frame b.
The utility model has the advantages that:
the utility model provides a piston engine valve spring lid and locking plate quick assembly disassembly tools, this utility model structure is simple, low in manufacturing cost, it is nimble to remove, can use in the engine valve spring lid and the locking plate dismouting of polytypic, only need one-man operation can realize that the dismouting of valve spring lid and locking plate is accurate, nimble swift simultaneously, the maintenance of applicable larger engine, whole dismouting process has been avoided using the hammer to strike hollow stick and has been leaded to the object to splash, make its maintenance process safer and more reliable.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in figure 1, 1-7 font support frame, 2-adjustable support frame a, 3-locating pin, 4-adjustable support frame b, 5-reset spring, 6-ejector pin, 7-pressure handle, 8-side opening.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in figure 1, the tool for quickly disassembling and assembling the valve spring cover and the locking plate of the piston engine comprises a support frame 1, an adjustable support frame a2, a positioning pin 3, an adjustable support frame b4, a return spring 5, a mandril 6, a pressing handle 7 and a side hole 8. In the embodiment, the support frame 1 is 7-shaped, the support frame 1 is provided with a movable adjusting positioning hole, an adjustable support frame a2 is installed on a 7-shaped vertical rod through a positioning pin 3, a side hole 8 for assembling and disassembling the locking plate is formed in the adjustable support frame a2, an adjustable support frame b4 is arranged on a 7-shaped transverse rod, a reset spring 5 is arranged at the bottom of the adjustable support frame b4, the bottom of the reset spring 5 is connected with an ejector rod 6, the ejector rod 6 is hinged to a pressing handle 7 through a unthreaded hole of the 7-shaped support frame 1, the other end of the pressing handle 7 is hinged to the adjustable support frame b4, and the pressing handle 7 compresses the valve spring to realize the assembling and disassembling of the valve spring cover and the locking plate.
The utility model discloses a working process: and selecting proper positioning holes to install and adjust the adjustable support frame a2 and the adjustable support frame b4 according to engines of different models, and fixing the tools at two ends of a valve and a valve spring on an engine cylinder cover after the tools are installed and fixed through the positioning pins 3. After the installation is finished, the pressing handle 7 is pressed forcibly, the valve spring is compressed, the locking plate is taken out from the side hole 8, the pressing handle 7 is loosened, the reset spring 5 is reset, and the valve, the valve spring cover and the valve spring can be taken out by removing the tool at the moment. The whole process is repeated reversely to install the valve, the valve spring cover and the valve spring. The whole disassembly and assembly process avoids the inconvenience that objects splash due to the fact that a hammer is used for knocking the hollow rod, and two persons use the hollow rod with one side provided with the groove at the same time; and only one set of tool is needed to realize the disassembly and assembly of the valve spring cover and the locking plate.
The utility model provides a piston engine valve spring lid and locking plate quick assembly disassembly instrument, the utility model discloses simple structure, low in manufacturing cost removes in a flexible way, can use in the engine valve spring lid and the locking plate dismouting of polytypic, only needs one-man operation can realize that the dismouting of valve spring lid and locking plate is accurate, nimble swift simultaneously, the maintenance of applicable bigger engine, whole dismouting process has avoided using the hammer to strike hollow stick and lead to the object to splash, makes its maintenance process safer and more reliable.
Finally, the above preferred embodiments are only intended to illustrate the technical solution of the invention and not to limit it, while the invention has been described in detail by the above preferred embodiments, it should be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention defined by the claims.
