Description

Technical Field

[0001] This utility model relates to the field of spring technology, and in particular to a strength testing device for spring production and processing. Background Technology

[0002] Spring strength testing is an important step in evaluating spring performance. Its main purpose is to determine whether the spring can maintain its shape and function under stress and to understand its fatigue life.

[0003] Patent CN220854446U discloses a spring compressive strength testing device. It includes a base plate with two sets of support columns fixedly mounted on it. A horizontal plate is fixedly mounted on the end of each support column away from the base plate. A movable plate is installed between the two sets of support columns. A second hook is mounted on the top of the movable plate, and a first limiting block is mounted on the end of the movable plate away from the second hook. Using this patent, pushing the movable plate causes the second hook to move one end of the spring, stretching the spring and testing its tensile strength. However, in the aforementioned prior art, the first and second hooks are respectively mounted on the movable plate and the connecting block. When the hook is damaged and needs replacement, corresponding tools are required, increasing preparation time. Furthermore, the lack of suitable tools can delay replacement operations and prolong downtime.

[0004] Therefore, there is a need for a strength testing device for spring manufacturing and processing that allows for quick assembly and disassembly of hooks. Utility Model Content

[0005] In order to overcome the disadvantages of the existing patents, where the first and second hooks are installed on the moving plate and the connecting block respectively, and when the hooks are damaged and need to be replaced, the corresponding tools need to be prepared, which increases the preparation time and the lack of suitable tools will delay the replacement operation and prolong the downtime, this utility model provides a strength testing device for spring production and processing with quick hook disassembly and assembly.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: A strength testing device for spring production and processing, comprising a mounting base, a guide frame, a fixed base, an electric guide rail, a slide block, and a fixing hook. The guide frame is fixedly connected to the mounting base, and the fixed base is fixedly connected to the guide frame. An electric guide rail is mounted on the guide frame, and a slide block is mounted on the electric slider of the electric guide rail. Fixing hooks are provided on both the slide block and the fixed base. The device also includes limit sleeves, mounting blocks, guide rods, sliding plates, insert rods, and electric push rods. Two limit sleeves are fixedly connected to both the slide block and the fixed base. Two mounting blocks are fixedly connected to the fixing hooks. Two guide rods are fixedly connected to both the fixed base and the slide block. Electric push rods are mounted on both the fixed base and the slide block. A sliding plate is mounted on the telescopic rod of the electric push rod, and two insert rods are fixedly connected to the sliding plate, with the insert rods inserted into corresponding mounting blocks.

[0007] Furthermore, it also includes a guide plate, a movable frame, a fixed plate, screws, and a dual-axis motor. The fixed plate is fixedly connected to the mounting base, and the dual-axis motor is mounted on the fixed plate. Screws are mounted on both output shafts of the dual-axis motor via couplings. Two guide plates are fixedly connected to the mounting base, and movable frames are threaded onto the screws.

[0008] Furthermore, it also includes a pressure detector and an alarm. The pressure detector is installed on the slide, and two alarms are installed on the slide. The alarms are electrically connected to the pressure detector.

[0009] Furthermore, a glass window is embedded in the moving frame.

[0010] Furthermore, the end of the insertion rod is rounded.

[0011] Furthermore, the mounting base has four mounting holes.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By aligning the insertion holes of the two mounting blocks of the fixed hook with the two adjacent insertion rods, after alignment, the electric push rod is activated. The extension rod of the electric push rod extends and drives the sliding plate to move backward along the guide rod. The sliding plate drives the two insertion rods to move backward and insert into the mounting block. In this way, the fixed hook can be installed quickly, and the fixed hook can be quickly disassembled and installed when it is damaged and needs to be replaced, thereby reducing equipment downtime.

[0013] 2. By starting the dual-axis motor, the two output shafts of the dual-axis motor drive the two screws to rotate respectively. The two screws drive the two moving frames to move towards each other along the guide plate. After closing, they form a protective barrier, which can prevent the spring from breaking and splashing out during the test, thereby protecting the staff.

[0014] 3. The spring tension is monitored in real time by a pressure detector, and the data is fed back to the control module. When the spring reaches the preset fracture threshold or abnormal deformation, the alarm is triggered immediately to remind the operator to stay away and take protective measures to avoid personal injury.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1: A strength testing device for spring manufacturing and processing, see reference. Figures 1-6 As shown, the device includes a mounting base 1, a guide frame 2, a fixed base 3, an electric guide rail 4, a slide block 5, and a fixing hook 6. The guide frame 2 is welded to the upper front side of the mounting base 1, and the fixed base 3 is welded to the lower part of the guide frame 2. The electric guide rail 4 is bolted to the guide frame 2 and is located above the fixed base 3. The slide block 5 is mounted on the electric slider of the electric guide rail 4. Both the slide block 5 and the fixed base 3 are equipped with fixing hooks 6, with the two fixing hooks 6 facing inwards. It also includes a limit sleeve 7 and a mounting block. 8. Guide rod 9, sliding plate 10, insert rod 11 and electric push rod 12. Two limit sleeves 7 are fixedly connected to both the slide 5 and the fixed seat 3. Mounting blocks 8 are fixedly connected to both sides of the fixed hook 6. Two guide rods 9 are fixedly connected to both the fixed seat 3 and the slide 5. Electric push rods 12 are installed on both the fixed seat 3 and the slide 5. Sliding plates 10 are installed on the telescopic rods of the electric push rods 12. The sliding plates 10 slide on the two guide rods 9. Two insert rods 11 are fixedly connected to the sliding plates 10. The insert rods 11 are inserted into the corresponding mounting blocks 8.

[0024] See Figure 3 As shown, the end of the insertion rod 11 is rounded to facilitate insertion into the mounting block 8.

[0025] See Figure 1 and Figure 2 As shown, mounting base 1 has four mounting holes.

[0026] When using this device, place the two fixed hooks 6 on the fixed base 3 and the slide 5 respectively, so that the insertion holes of the two mounting blocks 8 of the fixed hooks 6 are aligned with the two adjacent insertion rods 11. After alignment, start the electric push rod 12. The telescopic rod of the electric push rod 12 extends and drives the sliding plate 10 to move backward along the guide rod 9. The sliding plate 10 drives the two insertion rods 11 to move backward and insert into the mounting blocks 8. This allows for quick installation of the fixed hooks 6, and also allows for quick disassembly and assembly of the fixed hooks 6 when they are damaged and need to be replaced, thereby reducing equipment downtime and improving overall operating efficiency. After installation, hang the two ends of the spring to be tested on the fixed hooks 6 on the slide 5 and the fixed base 3 respectively, ensuring that the spring is horizontally fixed. When performing a tensile test, the electric guide rail 4 drives its own electric slider to move the slide 5 upward, applying tension to the spring to simulate the tensile state in actual use, thereby conducting a strength test.

[0027] Example 2: Based on Example 1, refer to Figure 1 , Figure 4 and Figure 5 As shown, it also includes a guide plate 13, a movable frame 14, a fixed plate 15, a screw 16, and a dual-axis motor 17. The fixed plate 15 is welded to the top of the mounting base 1. The dual-axis motor 17 is bolted to the middle of the fixed plate 15. Screws 16 are mounted on the two output shafts of the dual-axis motor 17 via couplings. The screws 16 rotate on the fixed plate 15. The guide plates 13 are symmetrically welded to the top of the mounting base 1. Movable frames 14 are threaded onto the screws 16. The movable frames 14 move on the guide plates 13. When the two movable frames 14 are closed, they can block the test area.

[0028] See Figure 1 , Figure 4 and Figure 5 As shown, a glass window is embedded in the movable frame 14.

[0029] Before testing, the dual-axis motor 17 is started. The two output shafts of the dual-axis motor 17 drive the two screws 16 to rotate. The two screws 16 drive the two moving frames 14 to move towards each other along the guide plate 13. After closing, they form a protective barrier, which can prevent the spring from breaking and splashing out during testing, thus protecting the staff. The observation window can also facilitate real-time observation of the spring test status.

[0030] See Figure 1 and Figure 6 As shown, it also includes a pressure detector 18 and an alarm 19. The pressure detector 18 is installed on the right side of the slide 5 by means of bolt connection. The pressure detector 18 contains a control module. The alarm 19 is installed symmetrically on the top of the slide 5 by means of bolt connection. The alarm 19 is electrically connected to the pressure detector 18.

[0031] During testing, the pressure detector 18 monitors the spring tension in real time and feeds the data back to the control module. If the spring reaches the preset fracture threshold or undergoes abnormal deformation, the alarm 19 is immediately triggered to remind the operator to stay away and take protective measures to avoid personal injury.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
