The spindle brake system is reasonable in structural design and high in brake precision.
Description
Technical field
The utility model relates to a kind of main shaft brake system, for lathe.
Background technology
Brake disc in existing brake system is gear shape, is furnished with gear brake structure, and gear brake structure engages with brake disc, by the rotating speed of gear brake structure restriction brake disc, and the rotating speed of brake disc restriction main shaft.Brake system brake precision is low like this.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design, the high main shaft brake system of brake precision are provided.
The technical scheme in the invention for solving the above technical problem is: a kind of main shaft brake system, comprise brake disc, and it is characterized in that: also comprise hydraulic jack, left brake bearing pin, right brake bearing pin, oil cylinder seat, oil supply system; Oil cylinder seat is fixedly installed; Hydraulic jack is arranged on oil cylinder seat, and hydraulic jack is connected with oil supply system; Left brake bearing pin and right brake bearing pin lay respectively at the both sides of brake disc, and left brake bearing pin is all connected with the piston rod of hydraulic jack with right brake bearing pin, and left brake bearing pin and right brake bearing pin are movably connected on oil cylinder seat.
Hydraulic jack described in the utility model comprises left hydraulic jack and right hydraulic jack, and left hydraulic jack and right hydraulic jack lay respectively at the both sides of brake disc; Left brake bearing pin is connected with the piston rod of left hydraulic jack, and right brake bearing pin is connected with the piston rod of right hydraulic jack.
Left hydraulic jack described in the utility model and right hydraulic jack are symmetrical arranged.
Left brake bearing pin described in the utility model and right brake bearing pin are symmetrical arranged.
Oil cylinder seat described in the utility model has groove, and described groove covers on brake disc, does not contact with brake disc; Left brake bearing pin and right brake bearing pin can stretch in groove.
The utility model compared with prior art, has the following advantages and effect: reasonable in design, brake precision is high.Oil supply system provides hydraulic pressure to hydraulic jack, and the piston rod of controlling hydraulic jack moves; In the time will braking, the piston rod piston rod of controlling hydraulic jack drives respectively left brake bearing pin and right brake bearing pin to move to brake disc direction, and be against respectively the two sides of brake disc, brake disc is produced to damping, reduce the rotating speed of brake disc, brake disc reduces the rotating speed of machine tool chief axis, plays braking effect.By the hydraulic pressure size that provides of oil supply system is provided, adjustable left brake bearing pin and the damping size of right brake bearing pin to brake disc, regulate the situation of change of brake disc rotating speed with this.
Accompanying drawing explanation
Fig. 1 is that the utility model embodiment is arranged on the structural representation on lathe.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1 and Fig. 2, the utility model embodiment comprises brake disc 1, hydraulic jack, left brake bearing pin 2, right brake bearing pin 3, oil cylinder seat 4, oil supply system 5, and hydraulic jack comprises left hydraulic jack 6 and right hydraulic jack 7.
Left hydraulic jack 6 and right hydraulic jack 7 are arranged on oil cylinder seat 4, and left hydraulic jack 6 is connected with oil supply system 5 with right hydraulic jack 7.Left hydraulic jack 6 and right hydraulic jack 7 lay respectively at the left and right sides of brake disc 1.Left hydraulic jack 6 and right hydraulic jack 7 are symmetrical arranged, and making to brake, precision is high, good stability.
Left brake bearing pin 2 and right brake bearing pin 3 lay respectively at the both sides of brake disc 1, left brake bearing pin 2 is connected with the piston rod of left hydraulic jack 6, right brake bearing pin 3 is connected with the piston rod of right hydraulic jack 7, left brake bearing pin 2 and right brake bearing pin 3 are movably connected on oil cylinder seat 4, left brake bearing pin 2 and right brake bearing pin 3 are symmetrical arranged, and making to brake, precision is high, good stability.
Oil supply system 5 left hydraulic jack 6 and right hydraulic jack 7 provides hydraulic pressure, and the piston rod of controlling left hydraulic jack 6 and right hydraulic jack 7 moves.In the time will braking, the piston rod of controlling left hydraulic jack 6 and right hydraulic jack 7 all moves to brake disc 1 direction, the piston rod of left hydraulic jack 6 and right hydraulic jack 7 drives respectively left brake bearing pin 2 and right brake bearing pin 3 to move to brake disc 1 direction, and be against respectively the two sides of brake disc 1, brake disc 1 is produced to damping, the rotating speed that reduces brake disc 1, brake disc 1 reduces the rotating speed of machine tool chief axis 9, plays braking effect.By the hydraulic pressure size that regulates oil supply system 5 to provide, adjustable left brake bearing pin 2 and the damping size of right brake bearing pin 3 to brake disc 1, the situation of change that regulates brake disc 1 rotating speed with this, the precision of hydraulic regulation is high, makes the utility model brake precision high.Be provided with in the situation of left hydraulic jack 6 and right hydraulic jack 7, can regulate respectively left brake bearing pin 2 and the damping size of right brake bearing pin 3 to brake disc 1, improved the utility model brake precision.
In addition, it should be noted that, the specific embodiment described in this description, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this description is only to the explanation of the utility model structure example.
