DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments:

[0026] As Figures 1 - 3As shown in the figure, the utility model provides a metal frame welding corner tooling fixture, which includes a fixed table 1. On the left and right sides of the top of the fixed table 1, there are fixed connection tooling fixtures 2. On the rear side of the top of the fixed table 1, there is a top alignment fixture 3 fixedly installed. On the front side of the top of the fixed table 1, there is an inner positioning fixture 4. The tooling fixture 2 includes an inclined limiting plate 21. The two inclined limiting plates 21 are respectively fixedly connected to the left and right sides of the top of the fixed table 1. On the opposite surfaces of the two inclined limiting plates 21, there is a three-axis cylinder 22 fixedly installed. The top output end of the three-axis cylinder 22 is fixedly connected with a connecting plate 23. On the top of the connecting plate 23, there is a sliding pressing plate 24 fixedly installed. On the lower surface of the sliding pressing plate 24, near one side of the inclined limiting plate 21, there is a pressing column 25 fixedly installed. The top alignment fixture 3 includes a three-axis cylinder 31. The three-axis cylinder 31 is fixedly installed on the rear side of the top of the fixed table 1. The front output end of the three-axis cylinder 31 is fixedly connected with a connecting plate 32. On the front side of the connecting plate 32, there is a positioning card plate 33 fixedly installed. In the middle of the front side of the positioning card plate 33, there is a right-angle card slot 34;

[0027] When welding and positioning a metal frame workpiece, place the workpiece on the fixed table 1. The inner positioning fixture 4 can limit the workpiece to prevent it from tipping over. Then, the three-axis cylinder 31 can push the connecting plate 32, so that the positioning card plate 33 can align and fix the workpiece through the right-angle card slot 34. At the same time, the three-axis cylinder 22 can drive the connecting plate 23 to slide downward, so that the sliding pressing plate 24 can drive the pressing column 25 to press down and clamp the workpiece tightly. When the workpiece is fixed, the top alignment fixture 3 releases and retracts. When the product welding is completed, the tooling fixture 2 rises and releases, which is convenient for taking out the workpiece.

[0028] As Figures 4 - 5 shown in the figure, the utility model provides a metal frame welding corner tooling fixture. The inner positioning fixture 4 includes a knob 41 and a connecting chute 43. The knob 41 is movably connected to the middle of the front side of the fixed table 1. The rear end of the knob 41 is fixedly connected with a transmission screw 42. The connecting chute 43 is opened on the front side of the top of the fixed table 1. The rear end of the transmission screw 42 penetrates into the inside of the connecting chute 43 and is threadedly connected with a threaded sliding plate 44 on its outer surface. The lower surface of the threaded sliding plate 44 is slidably connected with the inner wall lower surface of the connecting chute 43. On the left and right sides of the threaded sliding plate 44, there is a U-shaped fixture 45 slidably connected. On the top of the threaded sliding plate 44, there is a limiting chute 441. The inner surface of the limiting chute 441 is slidably connected with a right-angle top plate 442. The front end of the right-angle top plate 442 in the horizontal direction penetrates to the outside of the front side of the threaded sliding plate 44. The top end of the right-angle top plate 442 in the vertical direction is movably connected with a push rod 443. The top end of the push rod 443 is movably connected with the front side of the inner wall upper surface of the U-shaped fixture 45. The rear surface of the right-angle top plate 442 is fixedly connected with a top spring 444. The rear end of the top spring 444 is fixedly connected with the rear surface of the inner wall of the limiting chute 441;

[0029] By rotating the knob 41, the driving screw 42 can drive the threaded slide plate 44 to slide inside the connecting chute 43, and can drive the portal fixture 45 to slide, so that the right-angle top plate 442 can be released from the restriction. Under the pushing of the top spring 444, the right-angle top plate 442 can slide inside the limit chute 441, and then the portal fixture 45 can be pushed out of the connecting chute 43 through the push rod 443. By adjusting the distance between the portal fixture 45 and the inclined limiting plate 21, it is convenient to limit the workpiece when placing the workpiece, avoiding the tipping of the workpiece when fixing it, and facilitating the use of the welding fixture.

[0030] Next, the working principle of the metal frame welding corner fixture will be specifically described.

[0031] As Figures 1 - 5 shown, when welding and positioning the metal frame workpiece, by rotating the knob 41, the driving screw 42 can drive the threaded slide plate 44 to slide, and under the pushing of the top spring 444, the right-angle top plate 442 can push the portal fixture 45 out of the connecting chute 43 through the push rod 443. Then, the workpiece is placed on the fixed table 1. The workpiece can be restricted by the portal fixture 45 and the inclined limiting plate 21 to avoid the tipping of the workpiece. Then, the three-axis cylinder two 31 can push the connecting plate two 32, so that the positioning card plate 33 can be fixed to the workpiece through the right-angle card slot 34. At the same time, the three-axis cylinder one 22 can drive the connecting plate one 23 to slide downward, so that the sliding pressure plate 24 can drive the pressing column 25 to press and fix the workpiece downward. When the workpiece is fixed, the top alignment fixture 3 is released and retracted. When the product welding is completed, the fixture 2 rises and releases, facilitating the removal of the workpiece.

[0032] The above text generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
