Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Figure 1 to Figure 3, the embodiment provides a kind of vertical lathe workstation emergency braking apparatus, bags
Include brake disc 3 and emergency braking apparatus 4, emergency braking apparatus 4 includes stent 20, body 5, upper clamping plate 7, lower clamping plate 6, rubs
Pad group 8, hydraulic cylinder 14 and screw rod；
The brake disc 3 is arranged on 1 bottom outer of workbench, and workbench 1 is arranged on table base 2；
Organism 5 is fixedly installed on the stent 20, body 5 is U-shaped structure, and 5 internal upper part of body is provided with clamping plate 7, machine
Lower part is provided with lower clamping plate 6 in body 5, and upper clamping plate 7 and lower clamping plate 6 are flexibly connected respectively with 5 body wall axis pin 9 of body, on
Clamping plate 7 and the left side of lower clamping plate 6 are respectively arranged with friction plate group 8, and during energization, the distance of two groups of friction plate groups 8 is more than braking
The height of disk 3；
6 right end of lower clamping plate is fixedly installed locking nut 13, and adjusting screw 12 is provided in locking nut 13；
7 right end of upper clamping plate is fixedly installed hydraulic cylinder 14, and 14 upper end of hydraulic cylinder is sealed by hydraulic cylinder 19, hydraulic pressure
