Description
Technical field
The utility model relates to a kind of brake gear, particularly a kind of rotary table brake gear that is used for machining apparatus.
Background technology
Rotary table is one of critical piece in the machining apparatus, and the rotary table majority adopts the worm and gear drive unit to drive at present, because worm and gear has auto-lock function, so the rotary table of its driving need not brake gear.When adopting torque motor to drive rotary table, because self-lock force is less, when the needs rotary table stops, because installation or other operation of workpiece on anchor clamps, the moment that may rotate is if rotating torque greater than the self-locking moment of torque motor, can cause the rotation of rotary table, make troubles to machined, other unsafe factors also take place easily.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, reliable rotary table brake gear of flexible movements, makes workbench have enough brake torques when driving rotary table with the assurance torque motor.
Rotary table brake gear of the present utility model, the last fixed disk 1 and the lower fixed disk 9 that are mutually permanently connected are arranged, between last fixed disk 1 and lower fixed disk 9, be provided with the gap, the periphery limit of brake disc 7 is positioned at described gap, is provided with the clamping device of the clamping brake disc 7 that joins with control device between last fixed disk 1 and lower fixed disk 9.
Rotary table brake gear of the present utility model, wherein said clamping device structure is: be provided with piston 3 in the inboard of last fixed disk 1, one end of piston 3 is connected with oil-in 10 through oil duct 11, and described brake disc 7 is just between the other end and lower fixed disk 9 of piston 3.
Rotary table brake gear of the present utility model, wherein said oil-in 10 is located on the lower fixed disk 9.
Rotary table brake gear of the present utility model, wherein said piston 3 is provided with spring groove 14, and the center of piston 3 is provided with steel ball 4, is provided with the spring 5 that is used for return in spring groove 14 between last fixed disk 1 and steel ball 4.
Rotary table brake gear of the present utility model, because last fixed disk 1 and the lower fixed disk 9 that is mutually permanently connected arranged, between last fixed disk 1 and lower fixed disk 9, be provided with the gap, the periphery limit of brake disc 7 is positioned at described gap, between last fixed disk 1 and lower fixed disk 9, be provided with the clamping device of the clamping brake disc 7 that joins with control device, during installation brake disc 7 is fixed on the rotary table, rotate with rotary table, when needs braked, hydraulic control device moved by oil-in 10 driven plunger 3, made piston 3 and lower fixed disk 9 clamp brake disc 7, reach the purpose of braking, this moment, spring 5 deformed, and when the hydraulic oil off-load, spring 5 makes piston 3 returns, remove brake, flexible movements are reliable, and brake is firm, and is safe.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is an A portion enlarged drawing shown in Figure 1.
The specific embodiment
As shown in the figure: 1 is last fixed disk, 9 is lower fixed disk, fixedly connected by bolt 13 between last fixed disk 1 and the lower fixed disk 9 and be fixed on the support, rotary table is positioned in the middle of fixed disk 1 and the lower fixed disk 9, between last fixed disk 1 and lower fixed disk 9, leave the gap, the periphery limit of the brake disc 7 of fixedlying connected with rotary table just is positioned at the gap, is provided with the clamping device of the clamping brake disc 7 that joins with control device between last fixed disk 1 and lower fixed disk 9.This clamping device structure is: be provided with piston 3 in the inboard of last fixed disk 1, the oil duct 11 of one end of piston 3 in last fixed disk 1 is connected with oil-in 10, oil-in 10 is positioned on the lower fixed disk 9, and described brake disc 7 is just between the other end and lower fixed disk 9 of piston 3.Be processed with spring groove 14 on piston 3, the center of piston 3 is equipped with steel ball 4, is provided with the spring 5 that is used for return in spring groove 14 between last fixed disk 1 and steel ball 4.Spring 5 is a flap form, and the two ends screw is fixed on the fixed disk 1, and steel ball 4 is held in the centre.
During installation brake disc 7 is fixed on the rotary table, rotates, when needs brake with rotary table, hydraulic control device moves by oil-in 10 driven plunger 3, make piston 3 and lower fixed disk 9 clamp brake disc 7, reach the purpose of braking, this moment, spring 5 deformed, when the hydraulic oil off-load, spring 5 makes piston 3 returns, removes brake, and flexible movements are reliable, brake is firm, and is safe.
