[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides two technical solutions:

[0025] Figures 1-4 The first embodiment is shown: a welding bonding strength detection fixture for a universal steel back, comprising a workbench 1, a clamping mechanism 2 is symmetrically arranged on the top of the workbench 1 for fixing the steel material, and the two clamping mechanisms 2 each include:

[0026] The fixing assembly 21 comprises a bottom plate 211, a rotating seat 212 is symmetrically fixedly installed on the top of the bottom plate 211, a rotating shaft 213 is rotatably provided on the inner wall of the rotating seat 212, a rotating plate 215 is fixedly installed on the outer wall of one of the rotating shafts 213, a connecting plate 216 is fixedly installed on the outer surface of the rotating plate 215, a fixing column 217 is fixedly installed on the bottom surface of the connecting plate 216, an L-shaped mounting plate 218 is fixedly installed on the outer wall of the other rotating shaft 213, a driving motor 219 is fixedly installed on the top of the L-shaped mounting plate 218, a drill bit 2110 is fixedly installed on the output end of the driving motor 219, and the outer wall of the drill bit 2110 movably passes through the top of the L-shaped mounting plate 218 and extends to the bottom;

[0027] The placement component 22 includes a U-shaped frame 222, and a partition 225 is fixedly installed between the inner walls of the U-shaped frame 222. A through hole 226 is opened through the top of the partition 225. The through hole 226 can prevent the drill bit 2110 or the fixed column 217 from directly contacting the partition 225 to avoid interference or collision.

[0028] The bottom of the workbench 1 is fixedly installed with legs 11, and the workbench 1 is inclined to the left. When the workbench 1 is inclined, the clamping mechanism 2 on the right side is always in contact with the pressure sensor 31 on the hydraulic rod 3 under the action of gravity. A limit frame 4 is fixedly installed at a position near the right side of the top of the workbench 1. One of the bottom plates 211 is movably arranged inside the limit frame 4. By setting the limit frame 4, it plays a role in limiting and guiding the corresponding bottom plate 211. The other bottom plate 211 is fixedly installed at a position near the left side of the top of the workbench 1. A hydraulic rod 3 is fixedly installed at a position near the middle of the top of the workbench 1. The telescopic end of the hydraulic rod 3 is fixedly installed with a pressure sensor 31. The pressure sensor 31 is in contact with the outer surface of the right bottom plate 211. The pressure sensor 31 is a prior art. When an external force is applied, the elastic element deforms, and the strain gauge resistance pasted on it changes. The magnitude of the force is determined by measuring the resistance change. One end of the rotating shaft 213 movably penetrates the inner wall of the rotating seat 212 and extends to the outside. A worm gear 214 is fixedly installed at the end of the rotating shaft 213. A dual-axis motor 2111 is fixedly installed on the top of the bottom plate 211. Rotating rods 2112 are fixedly installed at both output ends of the dual-axis motor 2111. A worm 2113 is fixedly installed at the end of the rotating rod 2112. The worm 2113 is meshed with the worm gear 214. A bearing seat 2114 is rotatably arranged at a position near the end of the outer wall of the worm gear 214. The bearing seat 2114 is fixedly installed on the top of the bottom plate 211.

[0029] The drill bit 2110 is driven by the drive motor 219 to rotate at a high speed to drill a hole in the material. Then, the dual-axis motor 2111 is controlled to reverse the rotating rod 2112, and the L-shaped mounting plate 218 is folded outward. At the same time, the rotating plate 215 is folded inward to cooperate the drilled hole in the material with the fixing column 217. At this time, the fixing column 217 plays a role in fixing the material. Since the two ends of the material and the fixing column 217 are in shaft-hole fit, the phenomenon that the material slips during the tensile test due to insufficient clamping force is avoided, and the detection accuracy of the material is improved.

[0030] Figures 1-4The second embodiment is shown. The main difference from the first embodiment is that: four support plates 2115 are fixedly installed at a position near the middle of the top of the bottom plate 211. The surfaces of the opposite sides of the support plates 2115 are in contact with the sides of the U-shaped frame 222. An electric push rod 221 is fixedly installed at the bottom of the U-shaped frame 222, and the bottom end of the electric push rod 221 is fixedly installed on the top of the bottom plate 211. The outer wall of the U-shaped frame 222 is symmetrically threaded through with stud bolts 227. Knobs for convenient operation by personnel are provided at the ends of the stud bolts 227. Fixed plates 228 are rotatably arranged at the opposite ends of the stud bolts 227. The fixed plates 228 play a role in initially fixing the material to prevent displacement during the drilling process. Connecting blocks 223 are symmetrically and fixedly installed on the outer surfaces of both sides of the U-shaped frame 222. Guide posts 224 are movably arranged inside the connecting blocks 223. The bottom ends of the guide posts 224 are fixedly connected to the top of the bottom plate 211. Limit plates 229 for limiting the connecting plate 216 are symmetrically and fixedly installed at positions near the edges of the top of the U-shaped frame 222.

[0031] The U-shaped frame 222 can be supported by the support plates 2115 to avoid the instability of the U-shaped frame 222 when stretching the material, and reduce the lateral pressure on the guide posts 224. When the U-shaped frame 222 moves up and down, by providing the guide posts 224, the guide posts 224 play a role in guiding and limiting the U-shaped frame 222. When the connecting plate 216 contacts the top of the U-shaped frame 222, the connecting plate 216 is stuck between the two limit plates 229, so that the lateral surface of the connecting plate 216 can be limited to avoid the bending phenomenon of the connecting plate 216 during the tensile test, thereby improving the overall stability of the device.

[0032] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.

[0033] In use, place the material horizontally on the partition plate 225. Initially fix the material by turning the stud 227 in cooperation with the fixed plate 228. After that, start the dual-axis motor 2111 to drive the two rotating rods 2112 to rotate, and cooperate with the worm gears 2113 and worm wheels 214 on both sides to rotate in the same direction, so that the two rotating shafts 213 drive the rotating plate 215 and the L-shaped mounting plate 218 to turn over respectively. Due to the angular difference between the L-shaped mounting plate 218 and the rotating plate 215, when the L-shaped mounting plate 218 turns inwards, the rotating plate 215 turns outwards. When the drill bit 2110 is perpendicular to the partition plate 225, start the electric push rod 221, and cooperate with the U-shaped frame 222 to push the material on the partition plate 225 into contact with the drill bit 2110. Then, cooperate with the drive motor 219 to drive the drill bit 2110 to rotate at a high speed, so that a hole can be drilled in the material. After that, move the material downward through the electric push rod 221 to separate it from the drill bit 2110. Immediately afterwards, control the rotating rod 2112 to reverse through the dual-axis motor 2111, turn the L-shaped mounting plate 218 outwards, and at the same time, turn the rotating plate 215 inwards until the connecting plate 216 contacts the top surface of the U-shaped frame 222 and the connecting plate 216 is stuck between the two limit plates 229. At this time, the fixing column 217 is above the drilled hole of the material. Then, push the material upward through the electric push rod 221 to match the drilled hole in the material with the fixing column 217. At this time, the fixing column 217 plays a role in fixing the material. Finally, start the hydraulic rod 3 to make the pressure sensor 31 contact and squeeze the right bottom plate 211, so that the right bottom plate 211 moves away from the left bottom plate 211 until the material breaks, so as to achieve the detection effect. Since the two ends of the material and the fixing column 217 are in shaft-hole fit, the phenomenon of the material slipping due to insufficient clamping force is avoided, and the detection accuracy of the material is improved.
