Abstract
The utility model discloses an anti-drop device of an accessory milling head, relating to the technical field of mechanical equipment manufacturing. The anti-drop device comprises a movable ring connected with the accessory milling head, and a protective claw buckled with the movable ring, wherein an annular groove is formed in the side end of the movable ring; the protective claw is connected with one end of a piston arranged inside an oil cylinder; springs are arranged between the other end of the piston and the bottom of the oil cylinder; the oil cylinder is connected with an oil inlet fixed rod; the stroke of the protective claw and the piston is 4-10mm; and the stroke of the movable ring and the accessory milling head is 30-60mm. The anti-drop device can solve the problems of economical loss as the dropped accessory milling head that operators are injured, the precision of a machine tool is damaged, the accessory milling head is damaged, the surfaces of components are damaged, and the like.
Description
Technical field
The utility model relates to plant equipment manufacturing technology field, especially a kind of device of preventing that large-scale milling machine accessory milling head from coming off of being used to.
Background technology
At present, large-scale milling machine is to adopt hydraulic pressure, the accessories mill-head of tension automatically, owing to reasons such as hydraulic faults, when the accessories mill-head transposition, the main shaft claw exceeds predeterminated position, the main shaft claw opens, accessories mill-head comes off.Accessories mill-head comes off and may cause operating personnel injured, and machine tool accuracy is impaired, and the impaired and piece surface of accessories mill-head itself is destroyed etc., causes economic loss.
The utility model content
Technical problem to be solved in the utility model provides a kind of accessories mill-head anti-drop device, it can solve because of accessories mill-head comes off and may cause operating personnel injured, machine tool accuracy is impaired, and the impaired and piece surface of accessories mill-head itself is destroyed etc., causes the problem of economic loss.
In order to address the above problem, the technical solution of the utility model is: this accessories mill-head anti-drop device, include the circle and of living that is connected with accessories mill-head by the pawl that protects of hydraulic oil cylinder driving, the described circle of living is provided with described and protects the annular groove that dog clutch connects, piston one end of described oil cylinder is connected with the described pawl that protects, be provided with the compression spring between the described piston other end and the oil cylinder bottom, be connected with the oil-feed fixed bar on the described oil cylinder.
In the technique scheme, more specifically scheme can also be: described piston stroke is the 4-10 millimeter; The described circle stroke of living is the 30-60 millimeter.
Owing to adopt technique scheme, the utlity model has following beneficial effect:
1, can realize being contained in accessories mill-head ± 360 ° on machine ram or the main transmission box and prevent that automatically accessories mill-head from coming off when rotating or fixedly the time; even have accident also not come off during the accessories mill-head revolution; can effectively protect accessories mill-head, avoid the various infringements that accessories mill-head comes off and causes in the transposition process.
2, the utility model maximum speed can reach 50 rev/mins, and weight capacity is big, and maximum capacity is 1200 kilograms.
3, the utility model versatility is wide, can use on multiple Digit Control Machine Tool.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
The accessories mill-head anti-drop device of Fig. 1 comprises the accessories mill-head 2 that is sleeved on outside the circle 1 of living, the circle 1 of living is connected by the step of its cylindrical and the step of accessories mill-head 2 endoporus, fit clearance is in 0.1 millimeter-0.15 millimeter scope, circle 1 side of living is provided with annular groove, the claw that protects pawl 3 stretches in circle 1 annular groove of living and circle 1 snapping of living, the piston 4 that protects pawl 3 and be arranged in the oil cylinder 6 is fixedlyed connected by hexagon socket cap head screw, be provided with compression spring 5 between piston 4 other ends and oil cylinder 6 bottoms, be connected with oil-feed fixed bar 7 on the oil cylinder 6; Protect pawl 3 and piston 4 strokes are the 4-10 millimeter; Circle 1 alive and accessories mill-head 2 strokes are the 30-60 millimeter.
When accessories mill-head is loaded onto on the ram of Digit Control Machine Tool or the main spindle box, through the electrical control solenoid directional control valve on the Digit Control Machine Tool pressure oil is delivered in the oil cylinder 6 after pressure detecting mechanism detected pressures is normal by oil-feed fixed bar 7 oilholes, pressure oil promotes to protect the pressure that pawl 3 and piston 4 overcome compression spring 5 and retreats, the claw that protects pawl 3 withdraws from circle 1 annular groove of living, and 4 uniform blind rivets on live circle 1 and the body of milling head 2 and 4 uniform pulling claws on ram or the main spindle box are fused; Electrical control solenoid directional control valve outage on the Digit Control Machine Tool makes the pressure oil in the oil cylinder 6 flow back to fuel tank through beam hanger 7 holders and oil pipe; Compression spring 5 promotes to protect pawl 3 and piston 4, makes the claw that protects pawl 3 enter into the annular groove of circle 1 alive, has accident to come off when making accessories mill-head 2 revolutions, reaches the purpose of protection accessories mill-head 2.
