Description

Technical Field

[0001] This utility model relates to the field of connection strength testing technology, specifically to a connection strength testing device for electromechanical installation control. Background Technology

[0002] In electromechanical installation projects, ensuring the connection strength between various components is crucial. Insufficient connection strength may lead to problems such as unstable equipment operation and increased safety hazards.

[0003] Currently, most common electromechanical installation component connection strength testing devices adopt a single-station design. After completing the testing of one component, a considerable amount of time is required for material change before the next component can be tested. This results in a significant waste of time when testing electromechanical installation components in batches, seriously affecting the efficiency of the testing work. Utility Model Content

[0004] In view of the problems existing in the connection strength testing device for electromechanical installation control, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a connection strength testing device for electromechanical installation control, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A connection strength testing device for electromechanical installation control includes a base plate and a vertical plate. The vertical plate is fixedly disposed on one side of the upper surface of the base plate. A top plate is fixedly disposed on the upper end of the vertical plate. A hydraulic cylinder is fixedly disposed on the upper surface of the top plate. The piston rod of the hydraulic cylinder extends to the lower side of the top plate and is fixedly connected to a first U-shaped plate. A rotating rod is rotatably disposed between the lower sides of the top plate and the base plate. A motor is fixedly disposed on one side of the upper surface of the top plate. The output end of the motor is fixedly connected to one end of the rotating rod. A rotating block is fixedly sleeved on the rod wall of the rotating rod. Tension sensors are provided on both sides of the rotating block. The upper side of the tension sensor is fixed to the second U-shaped plate via a connecting rod. One end of the U-shaped plate abuts against the upper inner wall of the second U-shaped plate. A rotating plate is fixedly provided at the lower end of the rotating rod. A first limiting tube is fixedly provided on the upper surface of the rotating plate at a position corresponding to the two tension sensors. A second limiting tube is fixedly provided on the lower side of the tension sensor. A through hole is opened on the side of the first limiting tube and the second limiting tube away from the rotating rod. A clamping rod is slidably provided inside the through hole.

[0008] Preferably, a limiting mechanism is provided between the rotating block and the tension sensor to restrict the horizontal movement of the tension sensor relative to the rotating block. The limiting mechanism includes a vertical rod and a slider. Slide grooves are provided on both sides of the rotating block. The vertical rod is fixedly disposed inside the slide groove. The slider is movably sleeved on the wall of the vertical rod. One side of the slider is fixedly connected to the corresponding tension sensor.

[0009] Preferably, the upper surface of the rotating plate is provided with adjustment mechanisms on both sides to drive the clamping rod to move. The adjustment mechanism includes a bevel gear and an arc-shaped bevel rack. The upper surface of the rotating plate is fixedly provided with a base plate on both sides. A slide plate is slidably provided on the side of the fixed plate near the clamping rod. A strip-shaped opening is opened on the upper side wall of the slide plate. A sliding rod is fixedly provided inside the strip-shaped opening. A connecting block is movably sleeved on the rod wall of the sliding rod. One end of the lower clamping rod is fixedly connected to the slide plate, and one end of the upper clamping rod is fixedly connected to the movable block. A threaded rod is rotatably sleeved in the middle of the fixed plate. One end of the slide plate is threadedly sleeved with the threaded rod. A horizontal plate is fixedly provided on the side of the vertical plate near the rotating rod. A transmission mechanism for driving the threaded rod to rotate is provided on the upper side of the horizontal plate.

[0010] Preferably, the transmission mechanism includes a bevel gear and an arc-shaped bevel rack. The bevel gear is fixedly sleeved on one end of the threaded rod near the horizontal plate. The arc-shaped bevel rack is meshed on the lower side of the bevel gear on one side. The lower side of the arc-shaped bevel rack is fixedly connected to the horizontal plate. The arc-shaped bevel rack is concentrically arranged with the rotating rod.

[0011] Preferably, both the groove and the slider have rectangular cross-sections, and both sides of the slider abut against the inner wall of the groove.

[0012] Preferably, both the strip opening and the movable block have rectangular cross-sections, and both sides of the movable block abut against the inner wall of the strip opening.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model, with its unique design of dual tensile sensors and dual workstations, enables alternating operation of the two testing workstations. While the connection strength of electromechanical installation components is being tested at one workstation, material changing can be carried out simultaneously at the other workstation, significantly reducing the time spent on material changing. Compared with traditional single-workstation testing devices, this significantly improves the efficiency of batch testing of electromechanical installation components and effectively ensures the high efficiency of component connection strength testing in electromechanical installation projects.

[0015] 2. This utility model effectively limits the horizontal movement of the tension sensor relative to the rotating block through a limiting mechanism. The cooperation of the vertical rod and the slider ensures the stability of the tension sensor during the detection process. Even when the rotating block is rotating and under force, the tension sensor can still measure accurately, avoiding measurement errors caused by positional offset, improving the accuracy and reliability of the detection data, and providing strong support for the accurate assessment of the connection strength of electromechanical installation components.

[0016] 3. This utility model, through the cooperation of the adjustment mechanism and the transmission mechanism, can automatically clamp and release the object being measured. Through the meshing transmission of the bevel gear and the arc-shaped bevel rack, simply rotating the rotating rod will drive the threaded rod to rotate, thereby moving the sliding plate and clamping rod, thus enabling the clamping and release of the object being measured.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a connection strength testing device for electromechanical installation control.

[0026] Reference Figure 1-4 A connection strength testing device for electromechanical installation control includes a base plate 1 and a vertical plate 2. The vertical plate 2 is fixedly disposed on one side of the upper surface of the base plate 1. A top plate 5 is fixedly disposed at the upper end of the vertical plate 2. A hydraulic cylinder 4 is fixedly disposed on the upper surface of the top plate 5. The piston rod end of the hydraulic cylinder 4 extends to the lower side of the top plate 5 and is fixedly connected to a first U-shaped plate 6. A rotating rod 7 is rotatably disposed between the lower side of the top plate 5 and the base plate 1. A motor 3 is fixedly disposed on one side of the upper surface of the top plate 5. The output end of the motor 3 is fixedly connected to one end of the rotating rod 7. A rotating block 8 is fixedly sleeved on the rod wall of the rotating rod 7. Tension sensors 9 are disposed on both sides of the rotating block 8. The upper side of the tension sensor 9 is fixedly disposed on a second U-shaped plate 17 through a connecting rod 16. One end of the first U-shaped plate 6 abuts against the upper inner wall of the second U-shaped plate 17. Rotating rod 7 drives rotating block 8 to rotate, thereby rotating the upper ends of the second U-shaped plates 17 on both sides to the inner side of the first U-shaped plate. A rotating plate 10 is fixedly installed at the lower end of the rotating rod 7. A first limiting tube 11 is fixedly installed on the upper surface of the rotating plate 10 at the position corresponding to the two tension sensors 9. A second limiting tube 12 is fixedly installed on the lower side of the tension sensor 9. A through hole is opened on the side of the first limiting tube 11 and the second limiting tube 12 away from the rotating rod 7. A clamping rod 24 is slidably installed inside the through hole. When the piston rod of the hydraulic cylinder 4 retracts, it can drive the first U-shaped plate 6 to move upward. The first U-shaped plate 6 drives the corresponding second U-shaped plate 17 to move upward, thereby pulling the corresponding tension sensor 9. In this way, the strength of the material being tested, which is limited between the tension sensor 9 and the rotating plate 10, can be tested.

[0027] Reference Figure 1-4 A limiting mechanism is provided between the rotating block 8 and the tension sensor 9 to restrict the horizontal movement of the tension sensor 9 relative to the rotating block 8. The limiting mechanism includes a vertical rod 18 and a slider 19. Slide grooves are provided on both sides of the rotating block 8. The vertical rod 18 is fixedly set inside the slide groove. The slider 19 is movably sleeved on the rod wall of the vertical rod 18. One side of the slider 19 is fixedly connected to the corresponding tension sensor 9. The cross-section of the slide groove and the slider 19 are both rectangular. Both sides of the slider 19 abut against the inner wall of the slide groove, so that the slider 19 can slide stably in the slide groove.

[0028] Reference Figure 1-4The upper surface of the rotating plate 10 is provided with adjustment mechanisms on both sides to drive the clamping rod 24 to move. The adjustment mechanisms include a bevel gear 22 and an arc-shaped bevel rack 20. Fixed plates 13 are fixedly provided on both sides of the upper surface of the rotating plate 10. A sliding plate 14 is slidably provided on the side of the fixed plate 13 near the clamping rod 24. A strip-shaped opening is opened on the upper side wall of the sliding plate 14. A sliding rod 25 is fixedly provided inside the strip-shaped opening. A connecting block 23 is movably sleeved on the rod wall of the sliding rod 25. The cross-section of the strip-shaped opening and the moving block 23 are both rectangular. Both sides of the moving block 23 abut against the inner wall of the strip-shaped opening, so that the moving block 23 can stably move on the strip-shaped opening. The slide is slidable within the orifice. One end of the lower clamping rod 24 is fixedly connected to the slide plate 14, and one end of the upper clamping rod 24 is fixedly connected to the movable block 23. A threaded rod 21 is rotatably sleeved in the middle of the fixed plate 13. One end of the slide plate 14 is threadedly sleeved with the threaded rod 21. A horizontal plate 15 is fixedly installed on the side of the vertical plate 2 near the rotating rod 7. When the threaded rod 21 rotates, it will drive the slide plate 14 to move relative to the fixed plate 13, which in turn will drive the two clamping rods 24 to move. That is, it can clamp and limit the material to be measured between the first limiting tube and the second limiting tube. A transmission mechanism for driving the threaded rod 21 to rotate is provided on the upper side of the horizontal plate 15.

[0029] Reference Figure 1-4 The transmission mechanism includes a bevel gear 22 and an arc-shaped bevel rack 20. The bevel gear 22 is fixedly sleeved on one end of the threaded rod 21 near the horizontal plate 15. The arc-shaped bevel rack 20 is meshed on the lower side of the bevel gear 22 on one side. The lower side of the arc-shaped bevel rack 20 is fixedly connected to the horizontal plate 15. The arc-shaped bevel rack 20 is concentrically arranged with the rotating rod 7. The fixed arc-shaped bevel rack 20 allows the bevel gear 22 to rotate around its own axis when rotating around the rotating rod 7, thereby driving the slide plate 14 to move. When the bevel gear 22 and the arc-shaped bevel rack 20 are meshed, the slide plate 14 will drive the clamping rod 24 to automatically clamp the object being measured. When the bevel gear 22 and the arc-shaped bevel rack 20 are separated, the slide plate 14 will drive the clamping rod 24 to move away from the object being measured, automatically releasing the limit on the object being measured.

[0030] In this invention, during use, the two ends of the object to be tested (such as a connecting cable) are first placed inside the first limiting tube 11 and the second limiting tube 12. Then, the device is powered on and turned on. The motor 3 is started, driving the rotating rod 7 to rotate. The rotating rod 7 drives the rotating block 8 and the rotating plate 10 to rotate synchronously. During the rotation of the rotating plate 10, the bevel gear 22 in its surface adjustment mechanism rolls along the arc-shaped bevel rack 20, thereby driving the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the sliding plate 14 to slide relative to the fixed plate 13, thereby driving the clamping rod 24 to move, so that the clamping rod 24 automatically clamps the component. After the clamping rod 24 clamps the component, the hydraulic cylinder 4 is activated. The piston rod of the hydraulic cylinder 4 retracts, driving the first U-shaped plate 6 to move upward. The first U-shaped plate 6 pushes the second U-shaped plate 17, which it is in contact with, to rise. The second U-shaped plate 17 pulls the tension sensor 9 through the connecting rod 16. The tension sensor 9 applies tension to the component to detect the connection strength, and the detection data is transmitted in real time to the connected data acquisition device.

[0031] While inspection is being conducted at one workstation, workers at the other workstation remove the inspected parts and place new parts to be inspected. Once inspection is complete on one side, motor 3 reverses, and rotating rod 7 reverses 180°, exchanging the two workstations. At this point, the previously uninspected workstation begins inspection, while the inspected workstation performs a material change operation. During this process, the bevel gear 22 in the inspected workstation rolls in the opposite direction relative to the arc-shaped bevel rack 20, causing the corresponding threaded rod 21 to rotate in the opposite direction. This, in turn, causes the corresponding slide plate 14 to move away from the object being inspected, automatically releasing the limiting position of the inspected object and facilitating material change.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
