[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention.

[0020] Example

[0021] See also Figure 1-4 The utility model provides a technical solution: a welding point accuracy test bench for a welding robot, comprising a base 1, a plurality of docking slots 2 are provided on the top of the base 1 for positioning the detection area of ​​the welding robot, a plurality of the docking slots 2 are provided inside each of the docking slots 2 for testing the welding points of the welding robot, the detection component comprises a mounting frame 3 provided inside the docking slot 2, a through slot 301 is provided on the top of the mounting frame 3 for positioning the positions and angles of a plurality of top blocks 4, a plurality of top blocks 4 and positioning slots 5 are provided inside the through slot 301, the top block 4 is used to receive the welding robot during welding, and the positioning slot 5 is used to prevent the top block 4 from being subjected to welding shrinkage The angle is positioned when the upper block 4 is in the state of rotation. A connecting rod 401 is provided at one end of each of the top blocks 4. A latch tooth 402 is provided on both sides of the connecting rod 401. A spring 501 is provided inside each of the positioning grooves 5. The spring 501 is used to support the connecting rod 401 and push the connecting rod 401 to extend out of the cavity 6 to drive the top block 4 to reset. A plurality of cavities 6 are provided on both sides of the inner wall of the positioning groove 5. An electromagnet 601 and an electrical button 602 are provided on the inner wall of each of the cavities 6. The electromagnet 601 can generate magnetic poles when it is running and magnetically repel or attract the magnetic plate 8 on one side of the rack 7 (in the normal state, the electromagnet 601 repels the magnetic plate 8 and pushes the rack 7 to extend into the positioning groove 5). The rack 7 is extended and meshed with the outer wall teeth 402 of the connecting rod 401, thereby supporting and locking the connecting rod 401 and the top block 4; when the electromagnet 601 and the magnetic plate 8 are attracted to each other, the rack 7 can be driven to retract into the cavity 6, thereby pushing the top block 4 to reset through the spring 501). When the connecting rod 401 is retracted, the rack 7 is squeezed and retracted into the cavity 6 through the angle between the teeth 402 and the rack 7, and the electrical button 602 is pressed to send a signal to the main control center, so as to display the position of the retracted top block 4, and the cavities 6 at different heights in the positioning groove 5 represent the contraction amplitude of the top block 4 (the welding strength of the welding robot is tested by the contraction amplitude of the top block 4), and the electrical button 602 is pressed. A rack 7 is provided inside the cavity 6, and a magnetic plate 8 is provided on one side of the rack 7. When the welding robot is welding, the magnetic plate 8 is transmitted to the top block 4, which will drive the top block 4 to shrink into the mounting frame 3 (the contact between the welding wire and the workpiece will generate high temperature, causing the welding wire to melt rapidly and form a weld. In this process, the metal material will expand rapidly and generate huge thermal stress, causing a large local heat to be generated in the welding area. This combination of high temperature and high stress will cause impact force during the welding process, so that the top block 4 will shrink after welding). By corresponding the position of the shrinking top block 4 to the welding point set by the welding robot, the accuracy of the welding point can be tested by assisting visual and tactile detection.

[0022] In this embodiment, all electrical components are controlled by conventional controllers.

[0023] For example, please refer to Figure 1-4 , the mounting frame 3 is located in the docking groove 2 and is connected to the inner wall of the docking groove 2 by bolts, the through groove 301 is connected to the docking groove 2, and multiple top blocks 4 are located in the through groove 301 and are connected to the inner wall of the through groove 301 by a slide rail. The top block 4 is connected to the connecting rod 401 at one end near the through groove 301 by a bolt, and the other end of the connecting rod 401 extends into the positioning groove 5 and is slidably connected to the inner wall of the positioning groove 5. Multiple top blocks 4 are distributed in an array in the mounting frame 3, and the latch 402 is connected to the outer wall of the connecting rod 401 at one end of the positioning groove 5 by a bolt. Both ends of the spring 501 are connected to the inner wall of the positioning groove 5 and the connecting rod 401 by welding. The cavity 6 is communicated with the positioning groove 5 and is longitudinally arranged on both sides of the inner wall of the positioning groove 5. One end of the rack 7 is located in the cavity 6 and is slidably connected to the inner wall of the cavity 6 through a slide rail, and the other end extends into the positioning groove 5 and engages with the tooth 402 on the outer wall of the connecting rod 401. The electromagnet 601 is inlaid and connected to the inner wall of the cavity 6. The electromagnet 601 is magnetically connected to the magnetic plate 8 on the side of the rack 7 close to the inner wall of the cavity 6. The electrical button 602 is electrically connected to the main control center. When in use, the output end of the welding robot is first moved to the welding area (docking slot 2) on the base 1, and then the welding point is set, and the welding robot output is controlled to perform the welding operation. During welding, the top block 4 that undergoes welding in the docking slot 2 will shrink into the mounting frame 3 after welding, and the connecting rod 401 on the inner wall of the top block 4 will shrink in the positioning slot 5. At the same time, the latch 402 on the outer wall of the connecting rod 401 will squeeze the rack 7 at the angle of the rack 7 when moving, so that it shrinks into the cavity 6 to facilitate the movement of the connecting rod 401. At the same time, when the rack 7 shrinks, it presses the electrical button 602 in the cavity 6, so that it sends a signal to the main control center. After the connecting rod 401 shrinks, the extended rack 7 engages with the latch 402 to lock the position of the top block 4, and the signal emitted by the electrical button 602 in the cavity 6 at different heights is used to locate the shrinkage amplitude of the top block 4; the position of the shrinking top block 4 in the docking slot 2 is compared with the position of the welding point set by the welding robot, and the accuracy of the welding point is tested by visual and tactile detection.

[0024] The working process of the utility model is as follows: when in use, the output end of the welding robot is first moved to the welding area (docking groove 2) on the base 1, and then the welding point is set, and the welding robot output is controlled to perform the welding operation. During welding, the top block 4 in the docking groove 2 that receives welding will shrink into the installation frame 3 after being welded, and at the same time, the connecting rod 401 on the inner wall of the top block 4 shrinks in the positioning groove 5. At the same time, the tooth 402 on the outer wall of the connecting rod 401 squeezes the rack 7 at the angle of the rack 7 when moving, so that it shrinks into the cavity 6 for easy connection. When the rod 401 moves and the rack 7 contracts, it presses the electrical button 602 in the cavity 6, causing it to send a signal to the main control center. After the connecting rod 401 contracts, the extended rack 7 engages with the latch 402 to lock the position of the top block 4. The contraction amplitude of the top block 4 is determined by the signal sent by the electrical button 602 in the cavity 6 at different heights. The position of the contracted top block 4 in the docking groove 2 is compared with the position of the welding point set by the welding robot, and the accuracy of the welding point is tested by visual and tactile detection. The utility model realizes the contraction display of multiple receiving blocks during welding, the docking set welding point matching, the auxiliary testing of the welding point, and the detection of the welding effect, thereby improving the accuracy of the detection.
