Abstract

PURPOSE: A robot arm for a forging work is provided to manufacture a large quantity of forged products and improve the precision of the products. CONSTITUTION: Cylinders(2,22) are installed at both frames(1,11) having clampers(3), and move forward and backward, separately. Guide rails(6) are formed at support units(4,40), and are coupled to rail grooves(5,50) formed at the frames. A couple of guide bars and a small cylinder control the space between the support units. The cylinders and the support units are fixed to both fixed plates(9,10). A coupling unit easily controls the space between the fixed plates.

Description

Robot arm forging work {ROBOT ARM FOR FORGING}

The present invention relates to a robotic arm used for forging operations, and more specifically, it is possible to precisely move to a destination by picking up a plurality of workpieces, and can be easily forged in a state of holding a plurality of materials. It relates to the structure of a robotic arm that can be.

Forged robotic arm is known in the prior art, but can usually move in the required direction using the wrist joint and wrist joint, the structure to sandwich one material using a single forceps, simply to use one arm There is a problem that can not help to improve the workability and is not suitable for the difficult work for producing a variety of products.

The present invention has been made in view of the above-mentioned problems in the conventional structure using only one arm, and an object of the present invention is to provide a robotic arm having a new structure that can be dedicated to forging operations, and another object can be forged by sequentially picking up a plurality of materials. By providing a robot arm with a double-arm structure, it is possible to obtain the effect of mass production by continuous processing of the product.

In order to achieve the above object, the present invention is provided by arranging two sets of arms each having an independent forceps device and a retraction device side by side in order to simultaneously advance or retreat each of the forceps on both sides of the clamping material as necessary. It is configured to make it possible, and the gap adjusting device is installed between these two sets of arms, so that the gap between the arms is wide or narrow depending on the working conditions, so that various tasks with high difficulty can be easily processed and a plurality of materials At the same time, it was able to produce large quantities of products by processing.

1,11: Frame 2,22: Cylinder

3: forceps 4,40: support

5,50: Rail groove 6,60: Guide rail

7: guide rod 8: cylinder

12: Arm 13: Pressing Piece

The cylinders (2) and (22) are connected to the frame (1) (11) having the tongs (3), respectively, to facilitate the individual retracting operation of the frames (1) and (11), and the frame (1) (11). The guide rails 6 and 60 of the supports 4 and 40 are coupled to the rail grooves 5 and 50 formed on the inner surface of the frame, so that the frames can be retracted in a straight line without flow. A pair of guide rods 7 and a small cylinder 8 can be used to adjust the gap between them, and both fixing plates 9 to which the cylinders 2, 22 and the support 4, 40 are fixed. 10) is easily opened or retracted by the female coupling means, and one side of the support 4 is installed by connecting to the arm 12 installed to be able to rotate up, down, left and right.

The forceps device 3 is an elastic pinching operation in which the pressure piece 13 of one side is pinched or opened by the inner cylinder 14, and the other fixing piece 15 is integrally fixed to the frame so as not to move. It is.

According to the present invention configured as described above, the cylinders (2) (22) (8) (14) installed in each department are hydraulic or pneumatic cylinders, and operate by receiving instructions from a control device (not shown). The cylinder 14 of the operation is to hold or release the material (S), the cylinder (2) 22 connected to the frame alternates the forward and backward operation to advance or reverse the material bitten by the tong device and both frames if necessary. You can also advance to.

In addition, the cylinder 14 installed on the supports 4 and 40 is to adjust the gap between both frames by pushing or pulling the frame with the other support.

The robotic arm of the present invention is used by connecting to an arm 12 that can be rotated up, down, left, and right as shown in FIG. 2, and moves the robotic arm to a supply loaded with a large amount of material, respectively, on both clamping apparatuses 3. After sandwiching the (S) to move to the processing unit to put both materials at the same time or sequentially to be processed.

The above-described positional movement or rotational operation is performed by the arm 12, and the input operation of the material is performed by the cylinders 2 and 22 to advance and retract the frames 1 and 11, and the frames 1) ( 11 is fitted to the guide rails (6) 60 of the support (4) 40 to perform a sliding operation in a straight line.

In addition, when adjusting the input spacing of both materials (S) wide or narrow, while the cylinder 8 fixed to one support body 40 in the minimum closed state as shown in Figure 3 while pushing the other support (4) 5 and 6, the gap is widened.

Although the present invention has been described as a double structure for simultaneously processing two materials simultaneously or sequentially using both forceps devices, one material may be processed using only one forceps device among the double structure as needed, and frame It can also be used in a single structure by installing only one device such as a support.

The present invention can produce a large amount of products by simultaneously processing a plurality of materials by the double-armed forceps device, and can be processed precisely while retracting the material in a straight line by the retraction device, By installing the gap gap adjustment device, the gap width of both materials can be adjusted to match the mold position of the machined part.

Claims (2)

The cylinders (2) and (22) are connected to each of the frames (1) and (11) having the tongs (3), respectively, to facilitate individual retreat and to facilitate the rail grooves (5) and (50) of the frames (1) and (11). The guide rails 6 and 60 of the supports 4 and 40 are coupled to the support rails so that the frames can be retracted in a straight line without flow, and both supports 4 and 40 are paired with a pair of guide rods 7.
