Abstract
The utility model discloses a hanging ceiling fine-adjustment device of a front end of a main shaft box. Oil cylinders (2a, 2b) are arranged on a sliding pillow (1). cylinder covers (4) of the oil cylinders (2a, 2b) are fixed through nuts (3), and the oil cylinders (2a, 2b) are respectively provided with pistons (5a, 5b) facing the sliding pillow (1), and a pressure cavity is formed among the pistons (5a, 5b) and the cylinder covers (4). A draw bar (6) is connected with the oil cylinders through a connection rod. Two ends of the piston are sealed with sealing rings. The hanging ceiling fine-adjustment device of the front end of the main shaft box is simple in structure, and fast and convenient to install, low in cost and strong in practical value.
Description
Technical field
The field of machining that the utility model relates to refers more particularly to the technical field of improving machine finish.
Background technology
The spindle stock of large-sized numerical control floor type boring and milling machine, in assembling, the size at the elevation angle of main shaft and spindle stock side rails face directly influences the working accuracy of lathe.This elevation angle is along with the variation of the size of front end of spindle weight, and angle is in continuous change.Assembling is in the past handled it as a definite value constant, when front end of spindle weight changed, precision also changed, and this bed precision of machine is exerted an influence.Therefore can not simply be fixed as a definite value to it, there is a kind of anti-triangular number relation in response to the weight of this and front end of spindle in it with the spindle stock elevation angle, the weight increase, and the elevation angle reduces.Precision can keep stablizing when guaranteeing that machine tool chief axis uses the annex of different weight. and we have carried out improvement to spindle stock front end suspended ceiling device.
Summary of the invention
For solving the technical matters that exists in the prior art, the utility model provides a kind of spindle stock front end furred ceiling micromatic setting, at the spindle stock front end high-voltage oil cylinder is set, and changes the pressure of furred ceiling by the oil pressure size.
Spindle stock front end furred ceiling micromatic setting, described side's ram 1 is provided with oil cylinder 2a; 2b, the cylinder cap 4 of described oil cylinder is fixing by nut 3, described oil cylinder 2a; 2b is respectively equipped with the piston 5a towards square ram 1; 5b, piston 5a; Form pressure chamber between 5b and the cylinder cap 4, described pull bar 6 links to each other with oil cylinder by pipe link 7.
Seal ring seal is adopted at described piston two ends, and oil enters from the cylinder cap upper end, and along with the pressure size variation, piston rod moves up and down to reach and changes the spindle stock elevation angle, guarantees the stable of spindle stock side direction precision.
This micromatic setting is simple in structure, installs with convenient, fast, has very strong practical value at the bottom of the cost.
Description of drawings
Fig. 1 is the constructional drawing of the utility model spindle stock front end furred ceiling micromatic setting.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Spindle stock front end furred ceiling micromatic setting as shown in Figure 1, described side's ram 1 is provided with oil cylinder 2a; 2b, the cylinder cap 4 of described oil cylinder is fixing by nut 3, described oil cylinder 2a; 2b is respectively equipped with the piston 5a towards square ram 1; 5b, piston 5a; Form pressure chamber between 5b and the cylinder cap 4, described pull bar 6 links to each other with oil cylinder by pipe link 7.
Seal ring seal is adopted at described piston two ends,, oil enters from the cylinder cap upper end, and along with the pressure size variation, piston rod moves up and down to reach and changes the spindle stock elevation angle, guarantees the stable of spindle stock side direction precision.
The pressure of oil cylinder is controlled by hydraulic proportion valve, adjusts the change in location of front end of spindle.Electro-hydraulic proportional valve is controlled the electromagnet action by digital control system or PLC, and drive the decompression valve core and make electric current and the proportional relation output of pressure, be the size of electric current with the weight size conversion, carry out the hydraulic efficiency pressure system stepless voltage regulation.
Claims (2)
1. spindle stock front end furred ceiling micromatic setting, it is characterized in that: described side's ram (1) is provided with oil cylinder (2a; 2b), the cylinder cap of described oil cylinder (4) is fixing by nut (3), described oil cylinder (2a; 2b) be respectively equipped with piston (5a towards square ram (1); 5b), piston (5a; 5b) and between the cylinder cap (4) form pressure chamber, described pull bar (6) links to each other with oil cylinder by pipe link (7).
