Technical Field
[0001] This utility model relates to the field of sensor manufacturing technology, and in particular to a pressure head counterweight mechanism for power steering sensor assembly. Background Technology
[0002] During the sensor manufacturing process, a PHA press machine is required. The press head mechanism on the PHA press machine is used to press the wire harness and the sensor together to complete the assembly.
[0003] However, existing PHA press machines require operators to manually press down the press head mechanism during the pressing process, and also require operators to manually lift the press head mechanism after pressing is completed. The press head mechanism is relatively heavy, and the continuous pressing and lifting makes the operation labor-intensive and poses a risk of the press head falling. Utility Model Content
[0004] The purpose of this utility model is to provide a pressure head counterweight mechanism for power steering sensor assembly. During the pressing process, the operator manually pulls down the lever to move the moving seat downwards, thereby causing the counterweight to move upwards under the drive of the chain. After pressing is completed, the drive cylinder moves the moving seat upwards, thereby lifting the pressure head mechanism. The counterweight can balance the weight of the pressure head tooling and prevent the pressure head from suddenly falling. The drive cylinder moves the pressure head mechanism upwards, which can reduce the operating intensity.
[0005] To achieve the above objectives, a counterweight mechanism for assembling a power steering sensor is provided, comprising: a base, a right side plate and a left side plate fixedly connected to the top of the base, a sprocket assembly fixedly connected to the top of both the right side plate and the left side plate, a chain meshing on the sprocket assembly, a connecting block fixedly connected to one end of the chain, a counterweight block fixedly connected to the bottom of the connecting block, a connecting bracket fixedly connected to the rear side wall of the counterweight block, a slider fixedly connected to the connecting bracket, a guide rail fixedly connected to the left side wall of the right side plate, and the slider slidably connected to the guide rail.
[0006] According to the aforementioned power steering sensor assembly head counterweight mechanism, a front plate is fixedly connected to the front sidewall of the right side plate and the left side plate, a front slide rail is fixedly connected to the front sidewall of the front plate, a movable seat is slidably connected to the front side of the front slide rail, a gearbox is fixedly connected to the bottom of the movable seat, a head mechanism is rotatably connected to the bottom of the gearbox, a rotary motor is fixedly connected to the top of the gearbox, a pull rod is fixedly connected to the movable seat, a drive cylinder is fixedly connected to the right side plate and the left side plate, and the output end of the drive cylinder is fixedly connected to the movable seat.
[0007] According to the aforementioned power steering sensor assembly head counterweight mechanism, the number of sprockets is set to four, and they are symmetrically distributed on the right side plate and the left side plate, and the number of chains is set to two.
[0008] According to the aforementioned power steering sensor assembly head counterweight mechanism, the counterweight block, connecting bracket, slider, and guide rail are all located behind the front plate.
[0009] According to the aforementioned power steering sensor assembly head counterweight mechanism, the end of the chain furthest from the connecting block is fixedly connected to the movable seat.
[0010] According to the aforementioned power steering sensor assembly head counterweight mechanism, the gearbox is internally equipped with a gear set for rotation.
[0011] According to the aforementioned power steering sensor assembly head counterweight mechanism, the drive cylinder is located above the movable seat.
[0012] The above solution has the following advantages: By setting up a base, right side plate, left side plate, sprocket assembly, chain, connecting block, counterweight, connecting bracket, slider, guide rail, front plate, front slide rail, moving seat, gearbox, pressing head mechanism, rotary motor, pull rod, and drive cylinder, during the pressing process, the operator can manually pull down the pull rod to move the moving seat down, thereby causing the counterweight to move up under the drive of the chain. After pressing is completed, the drive cylinder drives the moving seat up, thereby lifting the pressing head mechanism. The counterweight can balance the weight of the pressing head fixture, preventing the pressing head from suddenly falling. The drive cylinder drives the pressing head mechanism to move up, which can reduce the operating intensity.
