Abstract
The utility model relates to a gravity center balance compensation device of a boring and milling machine main shaft box. The gravity center balance compensation device is suitable for a numerical control floor type boring and milling machine with a square ram. The main shaft box is connected with a counter weight through two sets of steel wire ropes, the counter weight is arranged in a stand column of the main shaft box, a main bearing rope is used for bearing the weight of the main shaft box, one end of the main bearing rope is connected with the counter weight, the other end of the main bearing rope is hung at the rear end of the main shaft box, one end of the compensation rope is hung on the counter weight, the other end of the compensation rope is hung on an oil cylinder piston rod fixed to the front end of the main shaft box, and an electro-hydraulic proportional valve is arranged on the front face of an oil cylinder. The main bearing rope and compensation rope two-hanging-point balance compensation method is adopted for the main shaft box of the compensation device, the magnitude of the pressure of the compensation oil cylinder is controlled through the electro-hydraulic proportional valve, and therefore the tension of the compensation rope accordingly changes, the gravity center displacement of parts of the main shaft box is compensated for by adjusting the tension distribution between the compensation rope and the main bearing rope through the counter weight, the main shaft box can be kept in the originally-balanced state, and the movement accuracy of the ram is ensured.
Description
technical fieldthe utility model relates to main spindle box gravity balance compensation arrangement, is applicable in the numerical control landing milling process bed with square ram.
background technologyin modernization milling-boring machine process, due to installation accessories, it moves the movement that is equivalent to whole annex to the ram in lathe.When ram moves, displacement changes, and it changes together with annex center of gravity, and main spindle box produces; When displacement request is increasing, boring machine middle pulley slideway certainly will cause wearing and tearing, not only affects the machining accuracy of boring machine to workpiece, and has affected the service life of whole boring machine.
Summary of the invention
The utility model is the technical problem in view of above existence, a kind of milling-boring machine main spindle box gravity balance compensation arrangement is provided, by the pulling force between counterweight adjustment compensation rope and main carrying rope, distribute, spindle box part displacement of center of gravity is compensated, thereby make main spindle box keep former poised state, guaranteed ram mobile accuracy.
To achieve these goals, the technical solution of the utility model is: milling-boring machine main spindle box gravity balance compensation arrangement, comprises main spindle box, counterweight, ram, main carrying rope, compensation rope, pulley, piston; Between main spindle box and counterweight, by two groups of steel wire ropes, be connected, counterweight is contained in main spindle box column, main carrying rope is in order to bear main spindle box weight, one end is connected with counterweight, the other end is hung in main spindle box rear end, compensation rope one end is hung on counterweight, and the other end is hung on the cylinder piston rod that is fixed on main spindle box front end, is provided with electro-hydraulic proportional valve before oil cylinder.
Described compensation arrangement, when ram stretches out while reaching a certain position, Electro-hydraulic Proportional Control oil cylinder working-pressure processed also changes thereupon, thereby makes the pulling force of compensation rope produce corresponding variation.By the pulling force between counterweight adjustment compensation rope and main carrying rope, distribute, make it to produce one to main spindle box righting moment, spindle box part displacement of center of gravity is compensated, thereby makes main spindle box keep former poised state, guaranteed ram mobile accuracy.
The beneficial effects of the utility model are: described compensation arrangement main spindle box adopts main carrying rope and the balanced compensated mode of compensation rope two suspension centre, by electro-hydraulic proportional valve, control compensating cylinder pressure size, thereby the pulling force that makes compensation rope produces corresponding variation, by the pulling force between counterweight adjustment compensation rope and main carrying rope, distribute, spindle box part displacement of center of gravity is compensated, thereby make main spindle box keep former poised state, guaranteed ram mobile accuracy.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
In figure, 1, main spindle box, 2, counterweight, 3, ram, 4, main carrying rope,, 5, compensation rope, 6, pulley, 7, piston.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
In figure, milling-boring machine main spindle box gravity balance compensation arrangement, comprises main spindle box 1, counterweight 2, ram 3, main carrying rope 4, compensation rope 5, pulley 6, piston 7; Between main spindle box 1 and counterweight 2, by two groups of steel wire ropes, be connected, counterweight 2 is contained in main spindle box 1 column, main carrying rope 4 is in order to bear main spindle box weight, one end is connected with counterweight 2, the other end is hung in main spindle box 1 rear end, compensation rope 5 one end are hung on counterweight 2, and the other end is hung on the cylinder piston rod 7 that is fixed on main spindle box front end, is provided with electro-hydraulic proportional valve before oil cylinder.
Described compensation arrangement, when ram 3 stretches out while reaching a certain position, Electro-hydraulic Proportional Control oil cylinder working-pressure processed also changes thereupon, thereby makes the pulling force of compensation rope 5 produce corresponding variation.The pulling force of adjusting 4, compensation rope 5 and main carrying rope by counterweight 2 distributes, and makes it to produce one to main spindle box 1 righting moment, main spindle box 1 parts displacement of center of gravity is compensated, thereby makes main spindle box keep former poised state, has guaranteed ram mobile accuracy.
