Specific embodiment

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.

A kind of fixed device of laser head, including clamping frame 1, bobbin winder device 15 and lifting device 3, the lifting device 3 have 4 It is a, and a rectangle is surrounded on work-yard 4, and be distributed in four corners of rectangle, the clamping frame 1 is located at the square Inside shape, there are four the bobbin winder device 15 is set, and it is sequentially connected respectively with each lifting device 3；Each coiling Rope 2 is wound on device 15, and the free end of the rope 2 is connect with the clamping frame 1 respectively.4 ropes 2 divide 1 pulling force of clamping frame is not given along 4 directions, laser head is housed in the clamping frame 1, because the laser head is straight not with workpiece Contact, therefore the pulling force that 4 ropes 2 provide can maintain the clamping frame 1 stable movement in the horizontal plane；Start 4 institutes Bobbin winder device 17 is stated, changes the length of the rope 2 between bobbin winder device 15 and the clamping frame 1 respectively, and then realizes institute The real-time movement of clamping frame 1 in the horizontal plane is stated, the lifting device 3 is gone up and down, and then drives the dress bobbin winder device 15, And it is gone up and down in the vertical direction by the clamping frame 1 that 4 ropes 2 on the bobbin winder device 15 are fixed.

Further, the lifting device 3 is hydraulic cylinder or cylinder, and the piston rod 5 of the hydraulic cylinder or cylinder prolongs upwards It stretches, the bobbin winder device 15 is separately fixed at 5 upper end of piston rod of the lifting device 3.The piston of the hydraulic cylinder or cylinder Bar 5 is flexible, and then the bobbin winder device 15 is driven to be gone up and down in the vertical direction.

Optionally, the device that the lifting device 3 can also be constituted for motor, bracket, screw rod and sliding block, the bracket are perpendicular Straight setting, and U-lag is equipped in vertical direction, the both ends of the screw rod are fixed on the two of the rack vertical direction by bearing End, the screw rod are threadedly engaged with the sliding block, and the sliding block can slide in the U-lag, and the motor is fixed on described The lower end of rack drives the screw rod to rotate, and then the sliding block is driven to move in the U-lag in the vertical direction.Institute It states sliding block and connects the bobbin winder device 15 far from the side of U-lag, the sliding block is mobile and then the bobbin winder device 15 is driven to exist It is gone up and down on vertical direction.

Further, the bobbin winder device 15 includes buckle 6, reel 7, electric machine support 8 and motor 9,6 card of buckle 5 upper end of piston rod for being fixed on the corresponding lifting device 3 is connect, the electric machine support 8 is horizontally fixed on the buckle 6 one Side, the motor 9 are mounted on the lower end of the electric machine support 8, and drive shaft is upward through the electric machine support 8, the motor 9 The upper end end of drive shaft be coaxially fixed with the reel 7, the rope 2 is wound on the reel 7.The coiling Wheel 7 is idler wheel, and the surface of the idler wheel is equipped with annular groove, and the rope 2 is wrapped in the surface of the annular groove, the motor 9 Starting, the drive shaft turns drive the reel 7 to rotate, and then wind or unclamp the rope 2, thus change it is described around The length of the rope 2 between line wheel 7 and the clamping frame 1, because the reel 7 is fixed in the horizontal plane, in turn The clamping frame 1 is driven to move in the horizontal plane；The piston rod 5 is flexible to drive the buckle 6 and the electric machine support 8 perpendicular Face interior movement directly, and then the clamping frame 1 for driving the rope 2 on the reel 7 and the reel 7 to connect is perpendicular Face interior movement directly.

Further, the lower end of the lifting device 3 passes through fixing seat 14 respectively and is fixed on work-yard 4.It is described solid 14 lower end surface of reservation is smooth, and upper surface is connect with the cylinder body of the lifting device 3, and the fixing seat 14 uses carbon steel material, Overcome the clamping frame 1 to the pulling force of the lifting device 3 and the influence of other external power using self gravity, makes whole device Stable stands on the work-yard 4, can be used for the big workpiece in big place, guarantees the stabilization in whole device operational process.

When applied to when small workpiece, the lifting device 3 further includes holder device, and the holder device includes support rod Fixed ring 10, support rod 11, connecting rod 12 and connecting rod fixed ring 13, outside the cylinder seat of the lifting device 3 from top to bottom according to It is secondary to be arranged with the support rod fixed ring 10 and the connecting rod fixed ring 13；The connecting rod fixed ring 13 is filled with the lifting It sets 3 cylinder seat to be slidably matched, the space outside of the support rod fixed ring 10 is uniformly distributed with the more support rods 11, often One end of support rod 11 described in root is hinged with the outer wall of the support rod fixed ring 10, and outside extends to the other end downwards It offseting with work-yard 4, the space outside of the connecting rod fixed ring 13 is uniformly distributed with the more connecting rods 12, and every One end of the connecting rod 12 is hinged with 13 outside of connecting rod fixed ring, and the other end is hinged with the support rod 11. The holder device is used to support whole device, and when work opens the support rod 11, when not working, collapses the support rod 11, the connecting rod fixed ring 13 is moved up and down, the connecting rod 12 is driven to rotate, and then realizes the gathering of the support rod 11 Or open, it is convenient that the holder device picks and places, and it is easy to operate, it is suitable for small place small workpiece.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
