Specific embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, becomes apparent from those skilled in the art How ground understanding practices the utility model.Although describing the utility model in conjunction with its preferred embodiment, these Embodiment only illustrates, rather than limits the scope of the utility model.

Referring to Fig. 1 to Fig. 3, a kind of fixture for door of elevator quadrangle laser welding, including latch segment 1, guide pad 2, Link block 3, linking arm 4, clamp seat 5, cushion block 6, top clamp 7, cylinder 8, cylinder push-rod 9, clamp pivoted arm 11, lower jaw 14。

The two sides of the latch segment 1 have been respectively fixedly connected with one piece of guide pad 2, and the guide pad 2 is blocky in isosceles trapezoid, Face where the short bottom edge of guide pad 2 and the side of latch segment 1 connect, and latch segment 1 and two pieces of guide pads 2 can be integral type Structure.

It is fixedly connected with link block 3 below the latch segment 1, is fixedly connected with linking arm below the link block 3 4, the linking arm 4 includes the block-like horizontal component of connection l-shaped and vertical portion, and the horizontal component and link block 3 are fixed Connection, upper end and the horizontal component of the vertical portion are linked together, and the lower end of vertical portion is fixedly connected with horizontally disposed One end of clamp seat 5, the clamp seat 5 is fixedly connected with the lower end of vertical portion, is fixedly connected with below one end of clamp seat 5 Cushion block 6, the other end of clamp seat 5 are fixedly connected with horizontally disposed top clamp 7, and clamp seat 5 is fixedly connected with cylinder above 8, the piston rod of the cylinder 8 passes through clamp seat 5 vertically downwardly, and is coaxially connected with cylinder push-rod 9, the cylinder push-rod 9 One end by the first pin shaft 10 and clamp pivoted arm 11 is hinged, and the middle part of the clamp pivoted arm 11 passes through the second pin shaft 12 and copper sheathing 13(copper sheathing 13 is alternatively at bearing) it is articulated on clamp seat 5, the other end of clamp pivoted arm 11 is fixedly connected with lower jaw 14, The lower jaw 14 is correspondingly set to below top clamp 7.

Referring to fig. 4, when the piston rod of cylinder 8 stretches out, piston rod linkage air cylinder push rod 9, clamp pivoted arm 11 and lower part folder Pincers 14, by lever principle, lower jaw 14 is close to top clamp 7, realizes the folder between top clamp 7 and lower jaw 14 Tightly.Referring to Fig. 5, when the piston rod of cylinder 8 is retracted, piston rod linkage air cylinder push rod 9, clamp pivoted arm 11 and lower jaw 14, By lever principle, lower jaw 14 realizes the opening between top clamp 7 and lower jaw 14 far from top clamp 7.

The top clamp 7 and lower jaw 14 include matrix pattern frame part and fixed part, the fixed part One end be linked together with the lattice in matrix pattern frame part, the other end of the fixed part of top clamp 7 and clamp seat 5 The other end is fixedly connected, and the matrix pattern frame part 701 and fixed part 702 of top clamp 7, lower jaw are shown in Fig. 3 The other end of 14 fixed part is fixedly connected with the other end of clamp pivoted arm 11；Top clamp 7 and lower jaw 14 are being quenched Teflon layer is coated with after fire, to prevent welding slag adhesion.

When work, for this fixture usually by robotic gripper, robot is mobile to be placed on four apex angles of door of elevator for fixture Welding position, cushion block 6 is against in the plate face of door of elevator, to make up the height between welding position and the plate face of door of elevator Difference.The welding position of apex angle each for door of elevator makes to need two pieces of metal plates welding just to be inserted in the upper of fixture at this Between portion's clamp 7 and lower jaw 14, the cylinder 8 on tracheae and fixture that then robot passes through certain length is connected, in turn Cylinder 8 is controlled to act.When cylinder 8 is ventilated, the piston rod of cylinder 8 stretches out, and lower jaw 14 is close to top clamp 7, thus by two Block metal board clamping, then carries out laser welding, and after the completion of welding, cylinder 8 loses heart, and the piston rod of cylinder 8 is retracted, top clamp 7 and lower jaw 14 unclamp.Fig. 6 to Fig. 8 shows the welding position using this fixture clamping 15 two apex angles of door of elevator, can To see that the external box of the matrix pattern frame part on top clamp 7 and lower jaw 14 can be compatible with clamping door of elevator 15 The lap of four apex angles, the matts that matrix pattern frame part inside divides then are stayed as welding two pieces of sheet metals Some welding regions (see Fig. 7 and Fig. 8), the matrix pattern frame part can also prevent other than the welding region of 15 apex angle of door of elevator Part be cauterized, influence appearance.To sum up, which ensures the Laser Welding Quality of door of elevator quadrangle.

It should be pointed out that can also have a variety of transformation and the implementation of remodeling for the utility model through absolutely proving Scheme, it is not limited to the specific embodiment of above embodiment.Above-described embodiment as just the utility model explanation, and It is not limitations of the present invention.In short, the protection scope of the utility model should include those for ordinary skill It obviously converts or substitutes and retrofit for personnel.
