The present invention relates to a device for fixedly installing a workpiece in an automatic welding system for welding a workpiece such as a boom or arm used for heavy equipment, and more particularly, depending on the model of the workpiece to be welded. The present invention relates to an automatic clamping device for a product of an automatic welding system that can be fixed to a welding position by setting a working position.

In general, in order to perform welding in an automatic welding system for welding a workpiece such as a boom or an arm used for heavy equipment, a device for fixing a workpiece (hereinafter referred to as a product) at a working position for a welding robot is required. In the conventional automatic welding system of the automatic welding system as shown in FIG. 1, the positioner 11 is fixedly installed on the ground, and a fastener 12 for fixing the product is formed at one side of the positioner 11. Since the structure and the length and height of the product to be welded are different, it is impossible to fix the product, so only one model of product can be fixed, and even if the same model has different dimensions, the product cannot be applied to the device. there was.

The present invention has been devised to solve the above problems, and it is possible to variably install and install various product models in the automatic welding system, and even if the same model product is used, the dimensional deviation caused by the same size dimensions. It is an object of the present invention to provide an automatic clamping device for a product of an automatic welding system that can be installed in a working position by controlling the product.

In order to achieve the above object, the present invention is installed in the positioner and the one side positioner which is installed on one side of the positioner and the upper side of the positioner and the positioner installed opposite to each other to enable left and right movement on the rail. It provides a product automatic clamping device of the welding automatic system which is mounted and driven by the fixture which is conveyed up and down.

Hereinafter, with reference to the accompanying drawings, the configuration of the subject innovation in detail as follows. First, as shown in FIG. 2, the welding robot 4 is installed in a gantry struture type, and the working part of the welding robot 4 is installed to move in the longitudinal direction and in the vertical direction. And positioners (1) and (1 ') moving rails (2) and (2') are installed on both sides of the rail (6) into which the product is carried. ) (1 ') is installed to move left and right respectively. As described above, the fasteners 3a, 3b, 3c, and 3d mounted on one side of the positioner 1, 1 'are rotated 360 ° as shown in FIGS. Rotating base plates (7) and (7 ') are installed, and base plates (7) and (7') are provided with LH type guide rails (8), and on the guide rails (8) an input sensor for clamping the product ( The cone type lug 9 (Conetype lug) equipped with S is mounted to slide. In addition, the lug 9 for clamping the product is installed in the center of the guide rail 8 so as to be screwed with the feed screw 10 so that the left and right feeds are possible, and the motor 40 is provided at one end of the feed screw 10. It is attached with 30. The other positioner 1 'has the same positioner 1 as that of the fixtures 3a, 3b, and 3c, but the guide rail 8' is mounted on the base plate 7 'so that the fixture 3b is vertically conveyed. ) Is installed and the sliding rail 12 is mounted on the guide rail (8 '), and is screwed with the feed screw (11). On the other hand, since the encoder 40 is installed in the motor 40, the product dimensions can be input memory, and the arbitrary dimensions can be stored in the motor 40, so that the products of various models can be clamped. Referring to the operation of the present invention configured as described above are as follows. First, when the truck 5 loads the product and carries it to the position of the positioner 1, 1, the sensor (not shown) of the positioner 1, 1 'detects the loading position according to the model of the product. Positioner (1) (1 ') is moved to position on the rail (2) (2'). When the positioner 1 (1 ') has finished positioning, the cart 5 loads the product to the position of the fixture 3a, 3b or the fixture 3c, 3d of the positioner 1, 1'. When the loading is completed, the hydraulic motor 40 mounted on the fixture 3a, 3b or 3c, 3d of the positioner 1, 1 'is driven to transfer the lug 9 to the product. After clamping, if a constant pressure is applied to the pressure sensor s mounted on the lug 9, the clamping completion signal is sent to the welding robot 4 to perform a welding operation. In addition, even if the same model is loaded with different dimensions, the transfer screw 11 of the fastener (3b) mounted on one side positioner (1 ') is transferred up and down to center the center position of the product. On the other hand, in order to clamp the product of the other model is loaded to the fixture (3c) (3d) is installed on the lower end of the positioner (1) (1 ') to perform the work by clamping.

According to the configuration and operation of the present invention can be useful when welding workpieces of different models or different dimensions, by installing a fixture that can clamp products of various models in the positioner, Since it can be effectively installed and applied, it is possible to improve the efficiency by shortening the welding time, and it is designed to have a flexible response effect in terms of product adaptability during welding work.
