Description

ROTARY TYPE WELDING JIG
The present invention relates to a welding jig, and more particularly, to a rotary welding jig capable of clamping the workpiece by adjusting the position of the clamping devices according to the type of the workpiece (Workpiece).
There are various kinds of welding such as spot welding, arc welding, laser welding, induction welding, brazing, and the like. The automobile industry manufactures a vehicle body by joining numerous parts made of ferrous alloys, nonferrous alloys, etc. by various welding. Welding systems in the automotive industry consist of robots and jigs for mass production.
There are two types of robots in the welding system: welding robots and feeding robots. The welding robot is equipped with a welding gun for welding the workpiece, and welds the workpiece clamped to the welding jig by the operation of the welding gun. The feeding robot moves the workpiece with respect to the welding gun and welds it. The welding jig has the function of a fixture for clamping the workpiece for welding the workpiece by the welding robot.
Welding systems can be easily found in many patent documents, such as Korean Patent Nos. 10-0907057, 10-0900070, and 10-0552613. The welding jig is equipped with a clamping device for clamping the workpiece. The workpiece is clamped and prepared by the clamping device. The welding robot operates the welding gun to weld the workpiece.
On the other hand, since the clamping device is configured exclusively to clamp a single workpiece accurately, when the workpiece is changed to another one, the clamping device must be replaced. However, since the welding system must be stopped for the replacement of the clamping device, there is a problem that the productivity is greatly reduced. In particular, in the multi-product small-scale production system, it is very important to establish a flexible manufacturing system that can flexibly cope with the change of the workpiece. The flexible production system is due to the dead time consumed for replacing the clamping device. It is a cause for greatly reducing the efficiency of the.
SUMMARY OF THE INVENTION The present invention has been made to solve various problems of the prior art, and an object of the present invention is to provide a rotary welding jig capable of clamping a plurality of types of workpieces by changing positions of platforms on which clamping devices are installed. In providing.
Another object of the present invention is to provide a rotary welding jig which can flexibly cope with a change in a workpiece and improve productivity.
A feature of the present invention for achieving the above objects includes: a mainframe installed on the floor in proximity to a welding robot for welding a plurality of types of workpieces placed on a workstation; A turning frame rotatably installed on the main frame and having a plurality of platforms; A plurality of clamping devices installed on the plurality of platforms so as to clamp each of a workpiece of a plurality of types of workpieces; It is installed on the main frame, there is a rotary welding jig including a drive means connected to the turning frame to rotate the turning frame.
The rotary welding jig according to the present invention can rotate the platforms on which the clamping devices are installed according to the type of the workpiece to change the position of the clamping devices, thereby accurately and stably clamping the workpiece by the dedicated clamping device. In addition, by building a flexible production system to cope with the change of the workpiece by preparing a dedicated clamping devices in advance in accordance with a plurality of types of workpieces for welding, it is possible to implement a high-productivity multi-line production line automotive production line.

Hereinafter, preferred embodiments of the rotary welding jig according to the present invention will be described in detail with reference to the accompanying drawings.
First, referring to FIG. 1, a rotary welding jig according to the present invention cooperates with a welding robot 10 to construct a welding system for welding a plurality of types of workpieces 2. The workpieces 2 may be variously selected, for example, a panel, a bracket, a beam, a bar, etc. constituting the vehicle body of the vehicle. The welding robot 10 is equipped with a welding gun 12 for welding the workpieces 2. The welding gun 12 welds the work pieces 2 placed in a work station 14 or an operational space by the operation of the welding robot 10.
1 to 5, the rotary welding jig according to the present invention includes a main frame 20 installed at the bottom of a factory. Main frame 20 is composed of a base (Base: 22) mounted on the bottom of the factory and the first post (24) and the second post (26) that is mounted at intervals on the upper surface of the base (22) It is. Base 22 is fixed to the bottom of the factory by a plurality of foundation bolts (28).
The rotary welding jig according to the present invention includes a turning frame 30 which is installed to rotate on the main frame 20. The turning frame 30 has a first axis 32 and a second axis 34 on both sides. The second shaft 34 is supported on top of the second post 26 by a bearing 36 for smooth rotation. In the present embodiment, the first shaft 32 may be supported on the upper part of the first post 24 by a bearing like the second shaft 34.
The turning frame 30 includes a plurality of beams 40 arranged in parallel between the first and second posts 24 and 26 and a plurality of support bars disposed outside the beams 40. bar 42 is configured as a tetrahedron having first to fourth platforms 44a to 44d. The support bars 42 are arranged in the same plane.
The face of any one of the first to fourth platforms 44a-44d, for example the first platform 44a, is in close proximity to the workstation 14 for welding of the workpieces 2 in cooperation with the welding robot 10. It is arrange | positioned upward so that it may be. When the first platform 44a is placed at the workstation 14, the second to fourth platforms 44b to 44d are waiting. In this embodiment, the turning frame 30 is shown and described that is composed of a rectangular parallelepiped having the first to fourth platform (44a ~ 44d), but this is illustrative and turning frame 30 is two or more It can be configured to have platforms. The two platforms may be configured to face each other, that is, the first platform 44a and the third platform 44c.
The rotary welding jig according to the present invention includes first to fourth clamping devices 50a to 50d installed for clamping the workpieces 2 to the first to fourth platforms 44a to 44d. Each of the first to fourth clamping devices 50a to 50d is configured in various ways to optimally clamp the workpieces 2 according to the size and shape of the workpieces 2. The first to fourth clamping devices 50a to 50d have a pair of fingers or jaws for clamping the workpieces 2 by driving an actuator. In addition, the first to fourth clamping devices 50a to 50d have a positioner for determining the positions of the workpieces 2 and a sensor for sensing the workpieces 2.
The rotary welding jig according to the present invention includes a motor 60 as driving means installed on one side of the main frame 20 to provide a driving force for the rotation of the turning frame 30. Motor 60 may be composed of an electric motor, a pneumatic motor. The reducer 62 is coupled to the motor 60 to reduce the driving force of the motor 60 and transmit it to the first shaft 32.
