Description

Technical Field

[0001] The utility model belongs to the technical field of hot-dip galvanizing, relates to a flat clamping claw hand for clamping a hot-dip galvanizing barrel, and also relates to an automatic claw hand device for clamping a hot-dip galvanizing barrel. Background Art

[0002] Hot-dip galvanizing is an effective way to prevent metal corrosion. Standard parts that need to be degreased and rusted are immersed in a zinc solution melted at about 500°C, so that a zinc layer is attached to the surface of the standard parts, thereby achieving the purpose of corrosion protection. At present, the industry usually uses flat jaws to manually clamp the barrel port, and completes hot-dip galvanizing through the process of finished product pickling-water washing-adding auxiliary plating solution-drying-dipping-cooling.

[0003] like Figure 1 As shown, the flat gripper of the prior art includes two semicircular grippers, which are respectively hingedly connected to two connecting rods. The two connecting rods 1 drive the two grippers to open and close through mutually meshing gear sets. The gear sets include two large gears 2 that respectively drive the connecting rods 1 to move and mesh with each other, and also include a small gear 3 that meshes with the two large gears 2 at the same time and a rack 4 that meshes with the small gear 3. The rack 4 moves through a barless cylinder 5. However, the disadvantages of this structure are: (1) The mechanism of the flat gripper is relatively complex and the manufacturing cost is high; (2) During use, the high temperature environment reduces the gap between the gears, which is prone to jamming and is more prone to damage after long-term use; (3) When the flat gripper is manually operated, the smoke and high temperature generated during zinc immersion cause great harm to the health of the galvanizing workers. Utility Model Content

[0004] In order to solve the above deficiencies in the prior art, the utility model aims to provide a flat clamping claw hand for clamping a hot-dip galvanized barrel, so as to achieve the purpose of reducing manufacturing costs, improving clamping smoothness, and extending service life;

[0005] The utility model also provides an automatic claw hand device for clamping a hot-dip galvanizing barrel, so as to achieve the purpose of preventing the zinc-immersion environment from causing harm to the workers.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A flat clamping jaw for clamping a hot-dip galvanized barrel, comprising a mounting shell and a first clamping jaw and a second clamping jaw both hinged on the mounting shell, and a driving device for driving the first clamping jaw and the second clamping jaw to open and close, wherein the driving device comprises a slider, a first connecting rod, a second connecting rod and a power mechanism;

[0008] The slider is slidably connected in the mounting housing, and the power mechanism is fixedly connected to the slider to drive the slider to perform linear motion along the mounting housing;

[0009] One end of the first connecting rod is hinged to the first clamping claw, and the other end of the first connecting rod is hinged to the slider. One end of the second connecting rod is hinged to the second clamping claw, and the other end of the second connecting rod is hinged to the slider.

[0010] As a limitation of the present invention, guide rails are fixedly disposed on both sides of the mounting shell, and both sides of the slider are respectively mounted on the guide rails.

[0011] As another limitation of the present invention, the power mechanism is a cylinder or an electric push rod fixedly mounted on the mounting housing.

[0012] As a limitation of the present utility model, the surfaces of the first clamping jaw and the second clamping jaw for clamping the barrel are both provided with anti-slip grooves.

[0013] An automated gripper device for clamping a hot-dip galvanized barrel comprises a robot and the above-mentioned flat gripper for clamping a hot-dip galvanized barrel, wherein the mechanical arm of the robot is fixedly connected to a mounting shell.

[0014] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0015] (1) The utility model uses linear motion instead of rotational motion, eliminating the complex gear set structure and greatly reducing the manufacturing cost. At the same time, it reduces the contact and fit between parts, avoids the influence of high temperature on the smoothness of movement, does not have the jamming phenomenon, reduces equipment maintenance, and prolongs the service life.

[0016] (2) The utility model is combined with a robot to realize unmanned and intelligent hot-dip galvanizing, improve work efficiency, and avoid the harm to the health of galvanizing workers caused by smoke and high temperature generated during galvanizing;

[0017] (3) The slider of the utility model moves along the guide rail, which improves the smoothness of the slider movement, has better guidance and stable movement;

[0018] (4) The anti-slip pattern of the utility model can improve the firmness of clamping and has strong practicality.

[0019] In summary, the utility model has a simple structure, low manufacturing cost, long service life, no harm to the human body, and is suitable for clamping cylindrical structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 2 , Figure 3 As shown, this embodiment includes a mounting housing 6, a first clamping jaw 7, a second clamping jaw 8 and a driving device. The mounting housing 6 is used to support the first clamping jaw 7 and the second clamping jaw 8, the first clamping jaw 7 and the second clamping jaw 8 are arranged opposite to each other and are used to clamp the barrel, and the driving device is used to control the opening and closing of the first clamping jaw 7 and the second clamping jaw 8 to grab or put down the barrel.

[0029] The shapes of the first clamping jaw 7 and the second clamping jaw 8 are existing structures, and the surfaces of both for clamping the barrel are arc-shaped, and the arc-shaped parts of both are symmetrically arranged. One end of the first clamping jaw 7 and the second clamping jaw 8 are both hinged in the mounting shell 6, wherein the hinge point between the first clamping jaw 7 and the mounting shell 6 is the first hinge point, and the hinge point between the second clamping jaw 8 and the mounting shell 6 is the second hinge point. The first hinge point and the second hinge point are separately arranged, and the arc-shaped ends of the first clamping jaw 7 and the second clamping jaw 8 both extend out of the mounting shell 6 for clamping the barrel. Anti-slip patterns 9 are arranged on the arc-shaped surfaces of the first clamping jaw 7 and the second clamping jaw 8 for clamping the barrel.

Guide rails 11 are fixedly arranged on both sides of the mounting housing 6. The guide rails 11 of this embodiment are cross roller guide rails. The moving direction of the guide rails 11 is arranged along the length direction of the first clamping jaw 7 and the second clamping jaw 8. Both sides of the slider 10 are respectively fixedly arranged on the cross roller guide rails on both sides, so that the slider 10 can move with the cross roller guide rails.

[0031] The power mechanism can be a cylinder 12 or an electric push rod. The power mechanism of this embodiment adopts a cylinder 12. A mounting plate 13 is fixedly provided on the mounting housing 6, and the cylinder 12 is fixedly provided on the mounting plate 13.
