Description
[technical field]
The utility model is about a kind of laser cutting head with electromechanical double protection.
[technical background]
In existing laser cutting technique, rely on the lifting of electric induction control Z axle to focus more.But because of a variety of causes, comprise malfunctioning or the like the reason of irregular, the circuit that is cut material, can cause the collision of cutting head and workpiece and cause whole cutting head to damage.The technology that has lean against that cutting is chewed and main body between add ceramic consumable accessory, change after the damage and protect the cutting head main body, replacing is wasted time and energy, and is uneconomical, also very unreliable; The technology that has then uses spring to solve as buffer unit, but trouble is installed in the collision back, can not accurately reset.So prior art has open defect: trouble is installed in the collision back, and it is undesirable to reset, and must manually go to regulate the position of cutting head, and lack automatically controlled protection, makes the collision probability high.
[utility model content]
The technical problem that the utility model institute desire solves provides a kind of one side and can reduce its collision probability as far as possible, can not damage element after protecting cutting head to be collided again, and can automatically reset electromechanical double protection cutter head device.
The technical scheme that the utility model adopted is: a kind of laser cutting head with electromechanical double protection, and comprise link block, focusing microscope base, distribution piece, cut and chew, laser cutting head connects by link block and Z axle; Focus in the microscope base focus lamp is housed, focusing on microscope base is installed between distribution piece and the cutting head body movably, the self-centering device is installed on the cutting head body and chews the jockey that is connected with cutting, the self-centering device is equipped with automatic runback device focus lamp being carried out can drive the jockey motion in the adjustment process on the jockey.
Laser cutting head also comprises hunting gear and sensing-controlling device, and hunting gear is followed the cutting motion of chewing and moved, and sensing-controlling device links to each other with hunting gear, and induction, control hunting gear move.
Described self-centering device comprises focusing nut, the locking nut that is installed on the cutting head body, and rotation focusing nut is adjusted and locked by locking nut the work focal length.
Described automatic runback device comprises back-moving spring and the location magnetic patch that is installed in the jockey.
The technique effect that the utility model reached is: the utility model adopts electric and mechanical duplicate protection scheme can reduce the collision probability of cutting head as far as possible; Comprise self-centering and two parts device that automatically resets in the Machine guarding of the present utility model again, bump, can not damage the cutting head element, and can automatically reset rapidly after the obstacle elimination as cutting head accident in service.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the installation diagram of the utility model electromechanical double protection device.
Fig. 2 is the part schematic diagram of the D part among Fig. 1, illustrates light path of the present utility model, gas circuit.
The figure number explanation:
1 link block, 2 distribution pieces 3 focus on microscope base
4 cutting head bodies, 5 focusing nuts, 6 connecting cylinders
9 cuttings of 7 cap bags, 8 fixed covers are chewed
10 follower disks, 11 location magnetic patch 12 back-moving springs
13 locking nuts, 14 sensing-controlling devices, 20 Z axles
[specific embodiment]
The utility model electromechanical double protection cutting head comprises machinery and electric two parts: mechanical part is made up of self-centering and runback bit position again; Electric part then is made up of servo-actuated and sense control part.
Operation principle: mechanical part
As shown in Figure 1, the utility model connects by the screw thread of link block 1 and the adapter of Z axle 20, thereby cutting head and Z axle are coupled as one.Link block 1 below is installed distribution piece 2 successively, is focused on microscope base 3, cutting head body 4, focusing microscope base 3 is plugged between the cavity of distribution piece 2 and cutting head body 4 formations, can insert from the outside or extract out, focus on microscope base 3 the insides focusing lens and lens orientation part are housed, focusing on microscope base 3 is separable with the part that focusing lens is installed, and eyeglass can also move the position with the adjustment center in focusing microscope base 3 the insides.
Pure air enters the focus lamp top by distribution piece 2, and airintake direction is shown in A arrow among Fig. 2, and the air that enters cools off the top of focusing lens; The pressure-air inlet is arranged on the cutting head body 4, and pure air can enter by air intake, and shown in B arrow among Fig. 2, the air that enters can cool off eyeglass from the focus lamp below.
Cutting is chewed 9 and is installed on the fixed cover 8, fixed cover 8 is equipped with cap bag 7 and is connected with connecting cylinder 6, between cap bag 7 and the connecting cylinder 6 back-moving spring 12 is housed, location magnetic patch 11 is housed between fixed cover 8 and the cap bag 7, the effect of wherein locating magnetic patch 11, back-moving spring 12 is to occur accident at work, as cutting head by collision and when crooked, as long as eliminate fault, it just can set back automatically and work on, and does not need manual intervention.
Operation principle: electric part
The electric part of the utility model electromechanical double protection cutting head comprises the follower disk 10 of chewing 9 motions with cutting, and cutting is chewed 9 and can be passed follower disk 10 along the Z axle.Follower disk 10 is connected with sensing-controlling device 14; sensing-controlling device 14 is connected with cutting head body 4; follower disk 10 is axial electric-controlled parts with sensing-controlling device 14; when cutting chew 9 along the Z axle is descending run into workpiece before; follower disk 10 sends signal to sensing-controlling device 14; thereby the axial stroke of control cutting head, the protection cutting head is not collided.
Operation principle: light path, gas circuit
As shown in Figure 2, the laser beam that comes from mirror unit enters cutting head by the C direction of arrow, and the focus lamp of installing on the line focus microscope base 3 focuses on back directive cutting and chews 9, chews 9 outputs by cutting and carries out work.The air that A arrow place enters cools off the top of focusing lens; The gases at high pressure that B arrow place enters can cool off the below of focusing lens, and gas is also chewed 9 ejections from cutting, to blow away the waste gas that cutting slag and cutting produce from workpiece.The airflow direction that A arrow, B arrow place enter is shown in the direction of arrow of inside.
