Abstract
The utility model discloses a braking device for a spindle of a turning and milling composite machine tool. The braking device comprises a brake disc (7), a pneumatic clamping device and an installing support (11). The brake disc is installed on the machine tool spindle. The pneumatic clamping device is fixed to a spindle box (12) of the machine tool through the installing support and comprises a piston rod (1), a piston (3), an end nut (2), an air cylinder (4), an air cylinder cover (5) and a braking clamping plate (6), wherein the piston rod is sleeved with the piston (3), the end nut (2) and the air cylinder cover (5), the piston (3) and the end nut (2) are covered with the air cylinder (4), the braking clamping plate (6) is arranged on the piston rod in a sleeved mode, closely attached to the outer end face of the air cylinder cover and provided an opening in the lower portion, the opening of the braking clamping plate aligns with and contains the brake disc installed on the machine tool spindle, the piston rod is located on the braking disc and penetrates through the braking clamping plate to be fixed by a nut (9), and the installing support is located at the outer end of the braking clamping plate. The spindle can be quickly braked and locked by the braking device when the turning spindle of the turning and milling composite machine tool needs to be stopped from rotating.
Description
Technical field
The utility model belongs to the apparatus structure technical field that the turning main shaft of complex milling machine tool is braked.
Background technology
Complex milling machine tool when work, workpiece be mounted in the joining chuck of lathe spindle on, in the time of Milling Process, require workpiece to stop operating, the requirement of guarantee Milling Process.On current turnning and milling complex centre lathe, major part is all to use band-type brake motor-locking main shaft.But because the transmission between motor and main shaft is to adopt belt transmission, therefore, in the time using Milling Function, the workpiece being connected with main shaft is just difficult to avoid having certain rotation, is difficult to guarantee the requirement of processing.In addition,, in the time that car, miller ex., the length consuming time that while shutdown due to turning main shaft, main shaft stops operating, has reduced production efficiency.
Summary of the invention
The defect that the purpose of this utility model exists in order to overcome above-mentioned prior art just, provides a kind of in the time requiring complex milling machine lathe turning main shaft to stop operating, can be rapidly by principal shaft braking, locked, and the complex milling machine tool spindle braking system that main shaft is not rotated.
The purpose of this utility model is achieved by the following technical solution.
A kind of complex milling machine tool spindle braking system, comprises brake disc, air pressure clamping device and mounting bracket three parts, and wherein brake disc is installed on machine tool chief axis, and air pressure clamping device is fixed on by mounting bracket on the main spindle box body of lathe; Described air pressure clamping device includes piston rod, be sleeved on piston and end nut on piston rod, cover on cylinder outside piston and end nut, be set in cylinder head on piston rod, be set on piston rod and be close to the brake clamping plate of the bottom band opening of cylinder head outer face, the brake disc being contained on machine tool chief axis is aimed at and contained to the opening part of brake clamping plate, piston rod is positioned on brake disc and through brake clamping plate to be fixed by nut, and mounting bracket is positioned at brake clamping plate outer end.
The utility model can be to turning principal shaft braking, locked, main shaft is not rotated or main shaft is stopped operating fast, and in the ensuing milling course of work, all always in locking state, thereby guarantee the processing request of milling, prevent that main shaft from rotating the mismachining tolerance producing.The stop operating problem of length consuming time of main shaft when effectively overcoming turning main shaft and shutting down.The utility model device compact overall structure, stable performance, manufacture and maintenance cost are low.
Accompanying drawing explanation
Fig. 1 is the utility model mounting structure schematic diagram;
Fig. 2 is air pressure clamping device internal structure and the schematic diagram that coordinates with brake disc thereof.
The specific embodiment
See Fig. 1, Fig. 2, a kind of complex milling machine tool spindle braking system, comprise brake disc 7, air pressure clamping device and mounting bracket 11 three parts, wherein brake disc 7 is installed on machine tool chief axis, and air pressure clamping device is fixed on by mounting bracket 11 on the main spindle box body 12 of lathe; Described air pressure clamping device includes piston rod 1, be sleeved on piston 3 and end nut 2 on piston rod, cover on cylinder 4 outside piston and end nut, be set in cylinder head 5 on piston rod, be set on piston rod and be close to the brake clamping plate 6 of the bottom band opening of cylinder head outer face, the brake disc 7 being contained on machine tool chief axis is aimed at and contained to the opening part of brake clamping plate 6, piston rod 1 is positioned on brake disc 7 and through brake clamping plate 6 to be fixed by nut 9 and packing ring 8, and mounting bracket 11 is positioned at brake clamping plate 6 outer ends.
The utility model is in the time that car, miller ex., spindle motor stops operating, and air pump is opened, and compressed air enters cylinder right ventricle promotion piston rod 1 and is moved to the left, piston rod promotes packing ring 8 by nut 9, packing ring 8 promotes brake clamping plate 6 right sides again to left movement, clamps brake disc 7, increases the frictional force between brake disc 7 and brake clamping plate 6, main shaft is stopped operating fast, and in the ensuing milling course of work, all always in locking state, thereby guarantee the processing request of milling.This installs compact overall structure, stable performance, and manufacture and maintenance cost are low.
