Description

Technical Field

[0001] This utility model relates to the field of frame welding, specifically to a frame welding test platform. Background Technology

[0002] In the existing technology, when welding the frame, the base plate is placed on a reference platform and flattened, and then spot welded to the reference platform. The approximate position of the reinforcing ribs is determined by marking lines on the base plate, the reinforcing ribs are placed and flattened, and any warped areas are pulled or flattened with G-clamps to facilitate welding. The same process is used to weld the surrounding plates. The welding sequence is from left to right (or from right to left) and from front to back (or from back to front). First, the internal reinforcing ribs are spot welded, and then the surrounding plates are spot welded. After the spot welding is completed, the entire frame is strip welded. Since the base plate may deform during the welding process, the welding frame is clamped with G-clamps on three or four sides for welding.

[0003] However, the following problems exist in the on-site manual welding process: the reference platform is not flat enough. The slag and burrs around the welding frame base plate placed on the platform have a great impact on the flatness of the placement. The on-site workers use hammers to tap around the edges to level it, and spot weld for pre-fixation. The same applies when spot welding the middle reinforcing ribs and the sheet metal around the edges. If there is any warping, G-clamps are used to pull or press it flat until the welding is completed. The leveling and positioning process consumes a lot of workers' time and also requires a certain level of experience from the workers.

[0004] Therefore, it is necessary to invent a frame welding test platform. Utility Model Content

Specifically, when the electromagnets 8 are running, they can generate magnetic attraction force, thereby conveniently magnetically fixing and positioning the base plate 1. Please refer to the appendix. Figures 4-6 The positioning and clamping assembly includes several fixed base plates 10, which are respectively fixed at the four edges of the top of the reference platform 7. Each fixed base plate 10 has a screw rod support locking block 11 fixed on its top. Each screw rod support locking block 11 has a screw rod 12 rotatably mounted on it. Each screw rod 12 has a handwheel 13 fixed at its end. Each screw rod 12 has a movable frame 14 threadedly connected to its surface.

Under the combined limiting action of the limit slider 16 and the slide rail 15, when the operator rotates the screw rod 12 in the forward and reverse directions through the handwheel 13, the movable frame 14 threadedly connected to the surface of the screw rod 12 can move back and forth in a stable linear manner. Each end of the movable frame 14 is fixed with a first positioning block 17, and each first positioning block 17 is fixed with a first spring plunger 18. The front and rear ends of several longitudinal reinforcing ribs 4 are respectively inserted into the inner side of several first positioning blocks 17 located on the front and rear sides of the top of the reference platform 7, and the first spring plunger 18 abuts against the surface of the longitudinal reinforcing ribs 4, so that several longitudinal reinforcing ribs 4 can be effectively clamped and fixed in position. The first positioning blocks 17 located on both sides of the top of the reference platform 7 abut against the surface of the two end plates 5, so that the two end plates 5 can be effectively clamped and fixed in position. Please refer to the appendix. Figures 7-8The rotary positioning assembly includes several fixed blocks 19, which are respectively fixed to the front and rear sides of the top of the reference platform 7.

Each transverse connecting rod 22 has several second positioning blocks 23 fixed on its surface. Each second positioning block 23 has a second spring plunger 24 fixed on its surface. Each second spring plunger 24 abuts against the surface of the transverse reinforcing rib 3. Specifically, under the action of the bearing 20, the longitudinal connecting rod 21, the transverse connecting rod 22 and the second positioning block 23 can rotate as a whole. It should be noted that a cylinder (not shown in the figure) is also fixed on the top of the reference platform 7. Driven by the cylinder, the longitudinal connecting rod 21, the transverse connecting rod 22 and the second positioning block 23 rotate as a whole, thereby clamping and fixing the transverse reinforcing rib 3. Please refer to the appendix. Figure 9 The clamping and leveling assembly includes several vertically arranged fixed rods 25. The bottom ends of the fixed rods 25 are all fixed to one side of the top of the reference platform 7. The top of each fixed rod 25 is rotatably mounted with a cantilever 26. The end of each cantilever 26 is fixed with a threaded sleeve 27. Each threaded sleeve 27 is threadedly connected to an adjusting screw 28. The bottom of each adjusting screw 28 is fixed with a clamping block 29. The bottom of the clamping block 29 abuts against the top of the end plate 5. Specifically, during the spot welding pre-fixing and welding process, if the base plate 1 deforms or the frame as a whole tilts, the operator can control the clamping block 29 to press down for leveling operations by rotating the cantilever 26 and the adjusting screw 28.

[0019] It should be noted that the test platform is electrically connected to an external main controller and 220V AC mains power, and the main controller can be existing technology devices such as computers that can be used for control.

[0020] The usage process of this utility model is as follows: When in use, the operator first places the base plate 1 on the reference platform 7, and uses the electromagnet 8 to run and clamp the base plate 1. The electromagnet 8 can only be released after the frame is welded. Then, the operator places the transverse reinforcing rib 3 on the top of the base plate 1, and uses the running cylinder to drive the longitudinal connecting rod 21, the transverse connecting rod 22 and the second positioning block 23 to rotate as a whole, thereby clamping and fixing the transverse reinforcing rib 3. Then, the operator places the longitudinal reinforcing rib 4 on the base plate 1 and turns the handwheel 13. The longitudinal reinforcing rib 4 is clamped and fixed by the first spring plunger 18 on the first positioning block 17. Then, spot welding is performed between the base plate 1, the transverse reinforcing rib 3 and the longitudinal reinforcing rib 4. If necessary during the spot welding process, the pressing block 29 can be pressed down by turning the cantilever 26 and adjusting the screw 28 to perform the leveling operation. After spot welding is completed, the operator loosens and resets the first positioning block 17 and the second positioning block 23, then places the side plate 2 and the end plate 5 on the base plate 1, and once again controls the first positioning block 17 located on the front and rear sides of the top of the reference platform 7 to clamp and fix the side plate 2 by rotating the handwheel 13, and controls the first positioning block 17 located on both sides of the top of the reference platform 7 to clamp and fix the end plate 5. Then spot welding is performed. If necessary during spot welding, the clamping block 29 can be pressed down by rotating the cantilever 26 and adjusting the screw 28 to perform leveling work. After spot welding is completed, the operator performs strip welding on the entire frame. If necessary during the strip welding process, the clamping block 29 can be pressed down by rotating the cantilever 26 and adjusting the screw 28 to perform leveling work. After the bar welding is completed, the first positioning block 17 is released and reset, and the electromagnet 8 is de-energized to release the base plate 1. Then the welded frame can be manually removed.
