[ technical field ] A method for producing a semiconductor device

The invention relates to an oil quantity adjustable oil pump structure for a chain saw and the chain saw, and belongs to the field of chain saws.

[ background of the invention ]

when a chain of the chain saw is used for sawing an object, a large amount of heat is generated due to friction, if the heat is not exhausted in time, the service lives of the chain and the chain saw are seriously influenced, and therefore the chain saw is generally provided with a chain lubricating system.

Because the chain saw needs different amounts of lubricating oil under different use conditions, most chain lubricating systems do not have the function of adjusting the amount of oil, and lubricating oil waste is caused. Some chain saws realize the oil quantity adjusting function through electronic control, and the production, use and maintenance costs are high.

[ summary of the invention ]

the invention aims to overcome the defects of the prior art and provides an oil quantity adjustable oil pump structure for a chain saw, which is manual and can conveniently adjust the flow of lubricating oil, and the chain saw.

The technical scheme adopted by the invention is as follows:

The utility model provides an adjustable oil pump structure of oil mass that chain saw was used, which comprises a housing, adjustment handle, the oil pump, the output shaft, driving pin and two at least turbine teeth, all turbine teeth are all installed on the driving pin, all turbine teeth set gradually along the driving pin axial, the driving pin is installed on the oil pump, the oil pump activity sets up on the casing, the output shaft is installed on the casing, turbine tooth and output shaft meshing, adjustment handle drives the oil pump at driving pin axial displacement to change the drive ratio of driving pin.

The invention has the beneficial effects that:

Through manual control adjustment handle, drive the oil pump through adjustment handle and produce the displacement at the driving pin axial, and then change the relative position between driving pin and the output shaft in the driving pin axial. Because all turbine teeth set gradually along the driving pin axial, consequently the driving pin can make different turbine teeth and output shaft produce the meshing along with the oil pump when self axial produces the displacement, has different transmission proportion between different turbine teeth and the output shaft, and then makes the lubricating oil of the different flow of oil pump output. The more the number of the turbine teeth is, the greater the flow regulating capacity of the lubricating oil, and the more the number of the turbine teeth and the transmission ratio between the turbine teeth and the output shaft are changed, so that the chain saw is suitable for chain saws with different specifications. The whole set of oil pump structure that the oil mass is adjustable does not have program control, relies on adjustment handle to carry out manual control, the user operation of being convenient for more, and the convenient degree of operation obtains very big promotion.

The invention also comprises an oil pump mounting seat, one of the machine shell and the oil scraping pump mounting seat is provided with a sliding block, the other one is provided with a sliding groove, the sliding block is connected in the sliding groove in a sliding way, the oil pump is arranged on the oil pump mounting seat, and the oil pump is movably arranged on the machine shell through the oil pump mounting seat.

The adjusting handle is rotatably arranged on the shell, the cam is arranged on the adjusting handle, the cam rotates to push the oil pump mounting seat to move axially along the sliding groove, and the return spring is arranged between the oil pump mounting seat and the shell.

the shell is provided with a rotating hole, the adjusting handle penetrates through the rotating hole and rotates around the axis of the rotating hole, and the shell is provided with a rotating limiting rib for limiting the rotation of the adjusting handle.

The adjusting handle is movably arranged in the axial direction of the rotating hole, so that the adjusting handle avoids the rotating limiting rib.

The adjusting handle is sleeved with a pressing spring, and two ends of the pressing spring are respectively propped against the cam and the shell.

the oil pump mounting seat is provided with the contact block, the contact block is arranged along the axial direction of the rotating hole, the cam abuts against the contact block, and the cam pushes the oil pump mounting seat through the contact block.

The cam of the invention is in the shape of a spindle.

The invention is characterized in that a fixed sleeve is arranged on the machine shell, a piston sleeve is arranged in the fixed sleeve, and the end part of a transmission pin is arranged in the piston sleeve.

A chain saw comprises an oil pump structure with adjustable oil quantity.
