Description

Technical Field

[0001] This utility model relates to the field of wire harness lubrication, and more specifically, it relates to a clock spring oil injection fixture. Background Technology

[0002] Clock springs are used in wiring harnesses connecting circuits such as the main airbag and steering wheel switch. They tighten or loosen with the rotation of the steering wheel, and lubrication can be improved by spraying oil on their surface. Existing spraying methods use a rotating fixture combined with manual spraying, which has the advantage of simple structure, but the disadvantages are that it is time-consuming, involves a lot of manual operation, and has correspondingly high labor costs. Utility Model Content

[0003] This invention overcomes the shortcomings of existing oil spraying methods that require manual labor, and provides a clock spring oil injection fixture that can automate the process except for loading and unloading, thereby reducing labor costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A clock spring oil injection fixture includes a fixture body, a fixture for positioning the clock spring, a rotating structure for driving the clock spring to rotate, a lifting cylinder capable of lifting and lowering, and an oil injection structure installed on the telescopic end of the lifting cylinder. The lifting cylinder is located directly above the fixture, and the lifting cylinder drives the oil injection structure to move closer to or away from the fixture along the height direction.

[0005] This application utilizes a fixture to position a clock spring. The downward-pressed oil spraying structure, aligned with the fixture's positioning of the clock spring, initiates oil spraying. During the spraying process, a rotating structure drives the clock spring to rotate, thereby uniformly spraying the strip within the clock spring. This device requires only manual loading and unloading, significantly reducing manual oil spraying steps, thus lowering labor costs and improving spray uniformity.

[0006] Preferably, the fixture body includes a guide plate with guide rails arranged along the height direction. The fixed end of the lifting cylinder is fixedly connected to the guide plate. The oil spraying structure is mounted on the oil spraying plate, which has a sliding groove that is slidably connected to the guide rails. The cooperation between the guide rails on the guide plate and the sliding grooves on the oil spraying plate guides the oil spraying plate, ensuring that the oil spraying structure accurately matches the fixture.

[0007] Preferably, the bottom of the guide plate is equipped with an adjustable positioning rod, and the spray plate is equipped with a positioning block. The adjustable positioning rod is threaded onto the guide plate, and its axial direction is set along the height direction. When the positioning block abuts against the adjustable positioning rod, the spray plate reaches its stroke limit. The threaded adjustable positioning rod, in cooperation with the positioning block, limits the stroke position of the spray structure, thereby ensuring accurate positioning of the spray structure.

[0008] Preferably, the fixture is equipped with a sensor for detecting the positioning status of the fixture and the clock spring. The sensor's detection direction is tangent to the edge of the preset installation position of the clock spring. The sensor emits and receives light, and determines whether the clock spring is properly installed in the fixture based on the received light or the reflection of the received light.

[0009] Preferably, the fuel injection structure includes several fuel injection valves arranged at equal intervals around a circumference, which is concentric with the clock spring. By setting several fuel injection valves concentric with the clock spring, the fuel injection speed can be increased and the fuel injection efficiency can be improved.

[0010] Preferably, the tooling body is equipped with an oil circuit control structure, which is connected to the fuel injection valve via a flexible pipeline. The tooling body controls the fuel supply through the oil circuit control structure. The flexible pipeline accommodates the vertical movement of the fuel injection structure.

[0011] Preferably, the rotating structure includes a servo rotary motor and a torque monitoring mechanism. The servo rotary motor outputs a torsion drive to rotate the clock spring; the torque detection mechanism can be a torque tester, which detects the output torque and compares it with a preset value. When the torque exceeds the limit, the servo rotary motor is stopped to prevent the belt inside the clock from breaking.

[0012] Preferably, the tooling body is equipped with a fixture seat for positioning the fixture, and the fixture is detachably connected to the tooling body. The detachable connection between the fixture seat and the fixture allows for adaptation to different types of clock springs by replacing the corresponding clock springs, thus increasing the flexibility of the tooling.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) By setting up a lifting oil spraying structure and a rotating structure that can drive the clock spring to rotate, the oil spraying is applied to the belt of the clock spring. The operator only needs to control it with a simple button. The automatic oil spraying except for loading and unloading can be achieved by controlling the controller that is electrically connected to the oil spraying structure and the rotating structure. (2) The tooling is equipped with a positioning block, an adjustable positioning rod, a torque detection mechanism, and a sensor that detects the position between the clock spring and the fixture, which eliminates several possible faults that affect oil injection and improves the reliability of the tooling.

[0020] Example: A clock spring oiling fixture, as described above. Figure 1 As shown, the fixture includes a tooling body 1, a fixture 2 for positioning a clock spring, a rotating structure for driving the clock spring to rotate, a lifting cylinder 3 capable of lifting and lowering, and an oil spraying structure mounted on the telescopic end of the lifting cylinder 3. The tooling body 1 has a plane of the positioning fixture 2, the lifting cylinder 3 and the oil spraying structure are located above this plane, and the rotating structure is located below this plane.

[0021] The lifting cylinder 3 is located directly above the fixture 2, and the lifting cylinder 3 drives the oil injection structure to approach or move away from the fixture 2 along the height direction. The tooling body 1 also has a controller electrically connected to the rotating structure, the lifting cylinder 3 and the oil injection structure. The controller controls the above components. A button connected to the controller is provided on the tooling body 1, and instructions are issued through the button to jointly control the operation of the above components.

[0022] As Figure 2 shown, the tooling body 1 includes a guide plate 4. A guide rail 5 is provided on the guide plate 4 along the height direction. The fixed end of the lifting cylinder 3 is fixedly connected to the guide plate 4. The oil injection structure is installed on the oil injection plate 6. The oil injection plate 6 is provided with a chute, and the chute is slidably connected to the guide rail 5. The cooperation between the guide rail 5 on the guide plate 4 and the chute on the oil injection plate 6 realizes the guiding of the oil injection plate 6, so that the oil injection structure can accurately fit the fixture 2. An adjustable positioning rod 7 is provided at the bottom of the guide plate 4, and a positioning block 8 is provided on the oil injection plate 6. The adjustable positioning rod 7 is threadedly connected to the guide plate 4, and the axial direction of the adjustable positioning rod 7 is along the height direction. When the positioning block 8 abuts against the adjustable positioning rod 7, the oil injection plate 6 reaches the stroke limit. The cooperation between the thread-adjustable adjustable positioning rod 7 and the positioning block 8 realizes the limitation of the stroke position of the oil injection structure, thereby ensuring the accurate positioning of the oil injection structure for the fixture 2.

[0023] The oil injection structure includes an oil injection valve 10. The number of oil injection valves 10 is several, and the oil injection valves 10 are arranged equidistantly around the circumference, and the circumference is concentric with the clock spring. By arranging several oil injection valves 10 concentric with the clock spring, the oil injection speed can be increased and the oil injection efficiency can be improved. An oil circuit control structure 11 is provided on the tooling body 1, and the oil circuit control structure 11 is connected to the oil injection valve 10 through a flexible pipe. The tooling body 1 controls the oil supply through the oil circuit control structure 11. The flexible pipe is used to adapt to the vertically moving oil injection structure. In some embodiments, the oil injection valve 10 is provided with a switch structure, and the on / off control of the oil injection valve 10 is realized by controlling the oil injection valve 10.

[0024] In addition to including a servo rotating motor 12, the rotating structure also includes a torque monitoring mechanism 13. The servo rotating motor 12 can accurately obtain its deflection angle relative to the zero position through electrical connection with the controller, so as to rotate back and pull back the belt of the clock spring after rotating a preset number of turns. The servo rotating motor 12 outputs torsional force to drive the clock spring to rotate; the torque detection mechanism can be a torque tester. The torque tester detects the output torque and compares the detected torque with the preset value. When it is over-limited, the servo rotating motor 12 is controlled to stop, avoiding the belt inside the clock being pulled off.

[0025] The fixture is equipped with a sensor 9 for detecting the positioning status of the fixture 2 and the clock spring. The detection direction of the sensor 9 is tangent to the edge of the preset installation position of the clock spring. The sensor 9 emits and receives light, and determines whether the clock spring is properly installed in the fixture 2 based on the received light or the reflection of the received light. The fixture body 1 is equipped with a fixture 2 seat for positioning the fixture 2, and the fixture 2 is detachably connected to the fixture body 1. The detachable connection between the fixture 2 seat and the fixture 2 allows for adaptation to different models of clock springs by replacing the corresponding clock spring, increasing the flexibility of the fixture.

[0026] This application uses fixture 2 to position the clock spring. The downward-pressed oil spraying structure, aligned with fixture 2 to position the clock spring, initiates oil spraying. During the spraying process, a rotating structure drives the clock spring to rotate, thus uniformly spraying the strip within the clock spring. This device requires only manual loading and unloading, significantly reducing manual oil spraying steps, thereby lowering labor costs and improving the uniformity of the spray.

[0027] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
