Abstract
The utility model provides a transverse beam locking device of a planer type milling machine. The transverse beam locking device of the planer type milling machine belongs to the technical field of planer type milling machines, and solves the problem that transverse beams of existing planer type milling machines are poor in locking effect. The transverse beam locking device of the planer type milling machine is arranged between the transverse beams and machine tool stand columns, and comprises a hydraulic cylinder, a nipper plate and a hinged plate, wherein a piston, a piston rod and a return spring are arranged in the hydraulic cylinder, one end of the piston rod stretches out the hydraulic cylinder and is hinged with one end of the hinged plate, the other end of the hinged plate is hinged with the nipper plate, the nipper plate is hinged on the other end of the hinged plate and is provided with a locking portion, and machine tool stand columns are provided with braking rails. The transverse beam locking device of the planer type milling machine uses a hydraulic pushing mechanical locking mode, is large and steady in locking force, and is rapid in loosing and locking control reaction, excellent in effect and high in safety.
Description
Technical field
The utility model belongs to the planer-type milling machine technical field, relates to a kind of crossbeam locking device of planer-type milling machine.
Background technology
Two AC servo motors are adopted in the lifting of present heavy planer-type milling machine crossbeam mostly, make two ball screws drive the crossbeam lifting by umbrella gear box, worm screw case.Tight by stopping behind the processing request location, because screw mandrel can not self-locking, the part planer-type milling machine carries out self-locking by worm and gear, and locking effect is undesirable.And when crossbeam vertical feed case and screw case were overhauled in maintenance, auto-lock function disappeared, and crossbeam must be propped up the jail, caused equipment damage and personal injury to prevent that crossbeam from gliding automatically.
Also has plenty of the employing hydraulic locking, locking device is made up of a hydraulic cylinder, the both sides cavity of hydraulic cylinder respectively feeds an oil inlet pipe, realize the move left and right of piston in the fuel-displaced mode in one side oil-feed one side, play locking or the purpose of unclamping locking device after making the connecting rod that connects piston reach anchor point, but because both sides all are the oil-feed devices, therefore in the position that is difficult to determine its pushing sometimes, do not know that locking still is relaxation state.Will produce a maloperation like this, and will directly influence the safe condition of human body when people's harm that the unexpected decline of crossbeam brings during in tool changing or other operation, safety coefficient is lower.
Summary of the invention
The purpose of this utility model is at existing the problems referred to above, and has proposed a kind of crossbeam locking device that adopts the planer-type milling machine of mechanical interlocking.
The purpose of this utility model can realize by following technical proposal: a kind of crossbeam locking device of planer-type milling machine, be arranged between crossbeam and the machine pillar, comprise hydraulic cylinder, nipper and articulated slab, be provided with piston, piston rod and back-moving spring in the hydraulic cylinder, it is characterized in that, one of described piston rod is stretched out hydraulic cylinder and hinged with articulated slab one end, the other end and the nipper of articulated slab are hinged, described nipper is hinged on the other end of above-mentioned articulated slab and is provided with tight lock part, vertically offers the track processed of stopping on the machine pillar.
In the crossbeam locking device of above-mentioned a kind of planer-type milling machine, described crossbeam locking device also includes the stroke induction installation, the stroke induction installation is travel switch, be arranged on hydraulic cylinder with respect to the opposite side of articulated slab, the other end of above-mentioned piston rod is stretched out and is pointed to travel switch from hydraulic cylinder equally.
In the crossbeam locking device of above-mentioned a kind of planer-type milling machine, described articulated slab is L-shaped, and the middle part is rotationally connected by bearing pin and crossbeam.
Compared with prior art, the crossbeam locking device of this planer-type milling machine adopts hydraulic drive mechanical interlocking mode, and coupling mechanism force is big, stable, and unclamps and lock the control reaction quick, effective, safe.
Description of drawings
Fig. 1 is the structural representation of planer-type milling machine.
Fig. 2 is structural representation of the present utility model.
Among the figure, 1, crossbeam; 2, column; 3, hydraulic cylinder; 4, nipper; 41, tight lock part; 5, articulated slab; 6, piston rod; 7, bearing pin; 8, travel switch.
The specific embodiment
As depicted in figs. 1 and 2, the crossbeam locking device of this planer-type milling machine is arranged between crossbeam 1 and the machine pillar 2, comprise hydraulic cylinder 3, nipper 4 and articulated slab 5, be provided with piston, piston rod 6 and back-moving spring in the hydraulic cylinder 3, hydraulic cylinder 3 is fixedly installed on the crossbeam 1, vertically offers the track processed of stopping on the machine pillar 2.
Stretch out from hydraulic cylinder 3 two ends respectively at two of piston rod 6, wherein one with articulated slab 5 one ends hinged, the other end of articulated slab 5 is also hinged with nipper 4, nipper 4 is provided with the tight lock part 41 of protrusion towards a side of the track processed of stopping, articulated slab 5 is L-shaped, and the middle part is rotationally connected by bearing pin 7 and crossbeam 1; Stretch out from hydraulic cylinder 3 tail ends the other end of piston rod 6, and point to a travel switch 8 that is fixedly installed on the crossbeam 1.
When operating system was sent " it is tight to stop " instruction, Hydraulic Station provided high pressure liquid oil to hydraulic cylinder 3, and piston rod 6 stretches out, and promotes articulated slab 5 and rotates.By the transmission of articulated slab 5, make nipper 4 towards track one lateral movement processed of stopping, the tight lock part 41 on the nipper 4 snaps in the track processed of stopping, and realizes the locking of crossbeam 1.
When crossbeam 1 need loosen, piston rod 6 retreated, and pulling articulated slab 5 and nipper 4 returns unlock.Touch travel switch 8 behind the piston rod 6 rollback certain distances, travel switch 8 sends the elevating mechanism that unlocking signal can start crossbeam 1, and crossbeam 1 is done and moved up and down.Respectively arrange such cover locking device on the left and right pillar 2, synchronously degree of tightness.
