Description
Technical field
The utility model is related to machinery field, specifically a kind of hydraulic pressure automatic brake mechanism.
Background technology
For heavy duty machine tools, balance weight thereon is to lift and carry out vertical displacement movement by steel wire rope, heavy
Amount it is light have several tons, 10-15 ton or more of weight, once steel wire rope is broken, will fall phenomenon, and initiation lathe damages
Bad or even personal injury, so must have corresponding safety measure.
Invention content
In order to overcome the shortcomings of that existing heavy duty machine tools balance weight can fall when steel wire rope is broken, this practicality is new
A kind of hydraulic pressure automatic brake mechanism of type offer, can be to balance weight when wire cable rupture using the hydraulic pressure automatic brake mechanism
Retarding braking is carried out, balance weight is avoided to fall.
The technical solution of the utility model is：A kind of hydraulic pressure automatic brake mechanism, including balance weight, steel wire rope, it is described
Balance weight top is fixed with load-bearing oil cylinder, and load-bearing oil cylinder top is connected with steel wire rope, and it is heavy that the balance weight two sides are provided with
Hole is fixed with the brake oil cylinder of horizontal direction in counterbore, and the piston rod end of the brake oil cylinder is fixed with brake block, and brakes
Piece is in contact with operation guide rail；It is connected by fluid pressure line between the load-bearing oil cylinder and brake oil cylinder.
The brake oil cylinder includes cylinder body, piston, is equipped with piston rod at piston centre, piston rod right end is fixed with brake
Piece, the piston by cylinder body be divided into left and right two cavitys, wherein left side inside cavity be equipped with disk spring, the cavity on right side with
Fluid pressure line communicates.
The utility model has the advantages that：Due to taking said program, balance weight to be fixedly arranged above load-bearing oil
Cylinder, both sides are fixed with brake oil cylinder, and the piston rod end of brake oil cylinder is fixed with brake block, and load-bearing oil cylinder and brake oil cylinder
Between be connected by fluid pressure line, once in this way, wire cable rupture, the disk spring in brake oil cylinder can pop up piston,
So that brake block is pressed on operation guide rail, to make balance weight slow down or braking, avoids balance weight from falling, it is flat to play protection
The effect of weight hammer, realizes safety in production.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of brake oil cylinder.
1- steel wire ropes in figure, 2- brake oil cylinders, 3- load-bearing oil cylinders, 4- operation guide rails, 5- balance weights, 6- guide rollers,
7- cylinder bodies, 8- disk springs, 9- pistons, 10- brake blocks, 11- fluid pressure lines.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
Shown in Fig. 1, Fig. 2, a kind of hydraulic pressure automatic brake mechanism, including balance weight 5, steel wire rope 1, the balance weight
5 tops are fixed with load-bearing oil cylinder 3, and load-bearing oil cylinder 3 is vertical direction, and piston rod top is connected with steel wire rope 1.The balance weight
It hammers 5 two sides into shape and is provided with counterbore, the brake oil cylinder 2 of horizontal direction is fixed in counterbore, the brake oil cylinder 2 includes cylinder body 7, piston
9, piston rod is equipped at 9 center of piston, piston rod right end is fixed with brake block 10, and the guide rail of brake block 10 and operation guide rail 4
Face is in contact.Cylinder body 7 is divided to control two cavitys by the piston 9, wherein the inside cavity in left side is equipped with disk spring 8, it is right
The cavity of side is communicated by fluid pressure line 11 with load-bearing oil cylinder 3.
When balance weight 5 is in promotion state, in piston effect to hydraulic oil of the gravity by load-bearing oil cylinder 3, and
Pressure is generated, pressure is transmitted to by fluid pressure line 11 in four brake oil cylinders 2, then pressure pushes brake oil cylinder piston 9 to start
Disk spring 8 is compressed, to make the brake block 10 of piston rod outer end leave the guide pass of operation guide rail 4, at this moment balance weight 5
It can freely move up and down.Once steel wire rope 1 is broken, then the hydraulic coupling in load-bearing oil cylinder 3 and brake oil cylinder 2 disappears,
To make the elastic force of the disk spring 8 in brake oil cylinder 2 be released, and push brake oil cylinder piston 9 by brake block 10 tightly
It is pressed on operation guide rail 4, generates reverse friction power so that balance weight 5 is braked or slows down, and the generation of falling accident is avoided.
Mechanism selects thickness, the diameter of disk spring 8 by adjusting the diameter of load-bearing oil cylinder 3 and brake oil cylinder 2
Or superposition the piece number, the size of hydraulic coupling and disk spring power can be matched, and finally can determine the brake weight size that friction generates,
It is adapted to the balance weight of different weight in this way.
