Description

Load bending special robot

Technical Field

The utility model belongs to the technical field of the robotechnology of using of bending and specifically relates to a load bending special purpose robot that says so.

Background

At present, the most applied method is that a 6-joint general industrial robot is matched with a bending machine to carry out combined following bending, along with the enlargement of the size of a sheet metal (200mm multiplied by 200mm → 2500mm multiplied by 1250mm), the general industrial robot is more and more difficult to consider the field of sheet metal bending, and particularly, the length parameter proportion of each shaft lever of the robot is not reasonable enough, so that the general industrial robot has many defects in bending application, such as a raised bending machine, a pit, a large interference area of the sheet metal and a robot body, and the like, a certain amount of modification has to be carried out on a workshop of a customer, and the total cost of a project is increased more; in addition, the bending auxiliary equipment adopts a beam structure, so that the equipment is frequently used in a factory, but the equipment occupies a large space and is inconvenient to disassemble.

Because the height of a knife edge of a bending machine is usually 900mm-950mm, when a general industrial robot in the market bends a plate with a large size, as shown in fig. 1, the interference between the general industrial robot and the plate is easy to occur, and in order to avoid the interference between the plate and the robot during bending, the robot is generally installed in a pit or the bending machine is lifted, so that the two modes not only increase the installation cost of equipment, but also are not easy to move.

SUMMERY OF THE UTILITY MODEL

1. Technical problem to be solved by the utility model

In to prior art, can take place plate and robot mutual interference's problem sometimes when bending special purpose robot, the utility model discloses a load special purpose robot that bends, it is through adding forearm seat extension, and the height restriction of corresponding big arm seat central line and base is in the half of edge of a knife terrain clearance, like this, under the prerequisite that does not influence the robot big, forearm arm exhibition, has solved the problem that both interfere.

2. Technical scheme

In order to achieve the above purpose, the utility model provides a technical scheme does:

a special robot for bending a load is a 6-joint industrial robot and comprises a base, a large arm seat, a large arm rod, a small arm seat, a small arm rod and a flange plate which are sequentially connected; the small arm seat is a lengthened small arm seat; the sum of the height of the center line of the large arm seat and the height of the base is less than half of the height of the bending machine from the ground of the knife edge; the height of extension forearm seat, restriction forearm seat and base need not to install the robot in the pit under the prerequisite that does not influence the robot big, forearm arm exhibition, perhaps raises the bender bed hedgehopping, has just solved the problem of the interference of this application.

The further technical scheme is that the knife edge height from the ground is 900mm-950mm, and the designed length of the center distance between the large arm seat and the large arm rod is 450 mm; the designed length of the center distance between the lengthened forearm seat and the forearm rod of the machine is 1100mm, and under the limit of the distance, the problem of interference cannot be caused when the long forearm and the short forearm are randomly unfolded.

Further technical scheme, when the ring flange was parallel with the base lower surface, ring flange upper surface was not more than 785mm apart from base lower surface minimum distance, and 785 mm's distance does not just have the emergence of the interference condition, and when being less than 785mm, more can not take place.

The further technical scheme is applied to large-size plates with the length larger than 1000mm, and the larger the specification is, the more the advantages of the application can be embodied.

3. Advantageous effects

Adopt the technical scheme provided by the utility model, compare with prior art, have following beneficial effect:

(1) the utility model discloses a special robot for bending load, the length of the small arm seat is lengthened, the height of the large arm seat and the height of the base are limited, and under the premise of not influencing the extension of the large arm and the small arm of the robot, the robot does not need to be installed in a pit or a bending machine is heightened, so that the problem that the plate and the robot are mutually interfered is solved;

(2) the utility model discloses a special robot for bending load, aiming at the range of the knife edge ground clearance of 900mm-950mm of the existing bending machine, the big arm length of 450mm and the small arm length of 1100mm, under the limit of the distance, the problem of interference can not be generated when the big arm length and the small arm length are randomly unfolded; the minimum distance between the upper surface of the flange plate and the lower surface of the base is not more than 785mm, the distance of 785mm is just not interfered, and the minimum distance is less than 785 mm;

(3) the utility model discloses a special robot bends in load is applied to length and is greater than 1000 mm's jumbo size plate, and the specification is big more, can embody this application advantage more.

Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings.

Example 1

The special load bending robot of the embodiment is a 6-joint industrial robot as shown in fig. 2, and comprises a base 1, a large arm seat 2, a large arm rod 3, a small arm seat 4, a small arm rod 5 and a flange plate 6 which are connected in sequence; the small arm seat 4 is a lengthened small arm seat; the sum of the height of the central line of the large arm seat 2 and the height of the base 1 is less than half of the height of the knife edge 11 of the bending machine 10 above the ground.

The utility model provides a load bending special purpose machinery people, the length of extension forearm seat, the height of restriction forearm seat 2 and base 1 do not influence under the prerequisite of robot big, forearm arm exhibition, need not to install the robot in the pit, perhaps bed hedgehopping with bender 10, has just solved the problem that this application plate and robot interfered each other.

Example 2

The basic structure of the load bending special robot of the embodiment is the same as that of the embodiment 1, and the difference and the improvement are that: as shown in fig. 1, when the knife edge 11 is applied to the ground, the height is 900mm-950mm, and the designed length of the center-to-center distance between the large arm seat 2 and the large arm rod 3 is 450 mm; the designed length of the center distance between the lengthened forearm seat and the forearm rod 5 of the machine is 1100mm, and under the limit of the distance, the problem of interference cannot be caused when the long forearm and the short forearm are randomly unfolded. The ring flange 6 is the J6 ring flange, and when being parallel with base 1 lower surface, J6 ring flange upper surface is not more than 785mm apart from base 1 lower surface minimum distance, and 785 mm's distance does not just have the emergence of the interference condition, when being less than 785mm, more can not take place.

Example 3

The basic structure of the load bending special robot of the embodiment is the same as that of the embodiment 2, and the difference and the improvement are that: when the device is applied to a large-size plate with the length of more than 1000mm, as shown in fig. 3, although the specification of the large-size plate 20 is 2500mm x 1250mm, and the height of the knife edge 11 of the bending machine is 900mm, the interference problem between the plate and a robot does not occur in the specific using process.
