Description

Technical Field

[0001] This utility model relates to the field of clock spring manufacturing technology, and in particular to a cutting device for clock spring manufacturing. Background Technology

[0002] A clock spring, also known as an airbag clock spring, is a special rotary connector or spiral cable. Its main function is to connect the main airbag and its wiring harness, or to connect the steering wheel switch buttons to the control unit's wiring harness. Clock springs are typically mounted on the combination switch below the steering wheel or on the pillar sheet metal to ensure that the electrical connections of components such as the front airbag and horn switch remain normal when the steering wheel is turned. Clock springs are usually made of steel strip, which needs to be cut to specific lengths during the manufacturing process for subsequent processing into springs.

[0003] Cutting steel strips involves the use of cutting devices. Traditional cutting devices typically employ a fixed-height design. While this design can meet basic cutting needs to some extent, it has significant limitations in actual production. Due to differences in worker height, fixed-height cutting equipment often fails to accommodate the operating habits of all operators. Shorter workers may need to frequently tiptoe, while taller workers may need to frequently bend over. This not only increases the labor intensity of the operators but may also lead to reduced work efficiency and increased operational errors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cutting device for the production of clock springs, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cutting device for producing clock springs includes a base frame, a drive assembly inside the base frame, a rotating rod inside the base frame via the drive assembly, a transmission assembly on the surface of the rotating rod, a screw on the surface of the rotating rod via the transmission assembly, a fixed frame rotatably connected to the surface of the screw, the fixed frame being fixedly connected to the base frame, a movable plate threadedly connected to the surface of the screw, the movable plate being slidably connected to the fixed frame, a connecting rod fixedly mounted on the top of the movable plate, the connecting rod being slidably connected to the base frame, a movable frame fixedly mounted on the top of the connecting rod, a processing table fixedly mounted on the bottom of the inner wall of the movable frame, a clamping assembly on the top of the processing table, and a cutting assembly inside the movable frame.

[0007] Preferably, the drive assembly includes a dual-axis motor disposed at the bottom of the inner wall of the base frame, a first bevel gear is fixedly mounted on the output end of the dual-axis motor, a second bevel gear is meshed on the surface of the first bevel gear, and the second bevel gear is fixedly connected to the rotating rod.

[0008] Preferably, the transmission assembly includes a third bevel gear disposed on the surface of the rotating rod, a fourth bevel gear meshing on the surface of the third bevel gear, and the fourth bevel gear being fixedly connected to the screw.

[0009] Preferably, the clamping assembly includes a support frame disposed on the top of the processing table, an electric push rod is fixedly installed on the top of the support frame, and a pressure plate is fixedly installed on the output end of the electric push rod.

[0010] Preferably, the cutting assembly includes a linear motor disposed on the top of the inner wall of the movable frame, a movable seat disposed on the linear motor, a hydraulic push rod fixedly mounted on the bottom of the movable seat, and a laser cutting head fixedly mounted on the output end of the hydraulic push rod.

[0011] Preferably, a fixing block is rotatably connected to the surface of the rotating rod, and the fixing block is fixedly connected to the base frame.

[0012] Preferably, there are multiple connecting rods, and the multiple connecting rods are symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Before the cutting device for clock spring production is used, the rotating rod is rotated by the drive component, which in turn drives the transmission component, causing the screw to rotate simultaneously. This causes the moving plate, connecting rod, moving frame, and processing table to move up and down simultaneously until the processing table moves to a suitable height. Then, the steel strip is fixed by the clamping component, and the steel strip is cut by the cutting component. The operator can adjust the height of the cutting platform according to their height and operating habits, avoiding the inconvenience of frequently bending over or tiptoeing to operate, and significantly improving the comfort of operation.

[0019] Reference Figure 1-3A cutting device for producing clock springs includes a base frame 1. A drive assembly is installed inside the base frame 1. A rotating rod 5 is mounted inside the base frame 1 via the drive assembly. A fixed block 6 is rotatably connected to the surface of the rotating rod 5 and is fixedly connected to the base frame 1 to ensure stable rotation of the rotating rod 5. The drive assembly includes a dual-axis motor 2 located at the bottom of the inner wall of the base frame 1. A first bevel gear 3 is fixedly mounted on the output end of the dual-axis motor 2. A second bevel gear 4 meshes with the surface of the first bevel gear 3 and is fixedly connected to the rotating rod 5. The device is driven by the drive assembly. The arrangement of the components facilitates the provision of driving force for the rotation of the rotating rod 5, allowing the rotating rod 5 to rotate simultaneously. A transmission assembly is provided on the surface of the rotating rod 5, and a screw 9 is mounted on the surface of the rotating rod 5 via the transmission assembly. The transmission assembly includes a third bevel gear 7 mounted on the surface of the rotating rod 5, and a fourth bevel gear 8 meshing with the surface of the third bevel gear 7. The fourth bevel gear 8 is fixedly connected to the screw 9. The transmission assembly facilitates transmission when the rotating rod 5 rotates, allowing the screw 9 to rotate simultaneously. A fixing bracket 10 is rotatably connected to the surface of the screw 9. The fixed frame 10 is fixedly connected to the base frame 1. A movable plate 11 is threadedly connected to the surface of the screw 9. The movable plate 11 is slidably connected to the fixed frame 10. A connecting rod 12 is fixedly installed on the top of the movable plate 11. There are multiple connecting rods 12, which are symmetrically distributed.

A processing table 14 is fixedly installed on the bottom of the inner wall of the movable frame 13. A clamping assembly is provided on the top of the processing table 14. A cutting assembly is provided inside the movable frame 13. This cutting assembly is used for the production of clock springs. Before the cutting device is used, the drive assembly rotates the rotating rod 5, which in turn drives the transmission assembly, causing the screw 9 to rotate simultaneously. This causes the moving plate 11, connecting rod 12, moving frame 13, and processing table 14 to move up and down simultaneously until the processing table 14 reaches a suitable height. Then, the clamping assembly fixes the steel strip, and the cutting assembly cuts the steel strip.

[0023] In use: The dual-axis motor 2 rotates the first bevel gear 3, the second bevel gear 4, the rotating rod 5, the third bevel gear 7, the fourth bevel gear 8, and the screw 9, causing the moving plate 11 to move up and down along the fixed frame 10, the connecting rod 12 to move up and down, and the moving frame 13 and the processing table 14 to move up and down until the processing table 14 reaches the appropriate height. Then, the steel strip is placed on the processing table 14, and the pressure plate 17 is moved downward by the electric push rod 16 to press the steel strip. Then, the laser cutting head 21 is moved downward by the hydraulic push rod 20 to move the laser cutting head 21 to the appropriate position, and then the steel strip is cut by the laser cutting head 21. At the same time, the linear motor 18 moves the moving seat 19 left and right, causing the hydraulic push rod 20 and the laser cutting head 21 to move left and right, so that the laser cutting head 21 completes the cutting of the steel strip.
