Description

Technical Field

[0001] This invention relates to the field of abrasive flow machining technology, specifically to a clutch abrasive flow precision polishing device. Background Technology

[0002] A clutch is used to connect shafts to achieve motion and torque. During machine operation, a clutch can disengage or engage the transmission system at any time. Clutches are mainly used for starting, stopping, reversing, and changing speed in mechanical transmission systems. Among them, the jaw clutch utilizes the interlocking or disengaging of teeth on the end faces of two clutch halves to achieve the engagement and disengagement of the driving and driven shafts. Teeth come in several forms, including rectangular, trapezoidal, triangular, sawtooth, and helical. Because a large number of teeth are engaged simultaneously, it has a high load capacity and a wide range of applications.

[0003] Abrasive flow machining is a novel machining method that uses an abrasive medium flowing under pressure over the surface of a workpiece to remove burrs, deflash, and round corners, thereby reducing surface roughness and achieving a precision-finished finish. Abrasive flow machining is the best choice for workpieces requiring complex manual finishing, those with intricate shapes, and areas that are difficult to machine using other methods.

2. The clutch abrasive flow precision polishing equipment according to claim 1, characterized in that: When the lead screw is rotated in the forward direction, the nut slider moves along the second slide rail groove towards the upper end away from the lead screw. When the upper surface of the fixture moving slider base is not in contact with the fixture cover plate, that is, when the fixture moving slider moves smoothly along the first slide rail, the spring is in a compressed state. Therefore, the fixture expanding slider, the fixture moving slider, and the positioning clamping jaws move forward along the first slide rail without relative motion under the action of the connecting rod. When the upper surface of the fixture moving slider base moves to contact the fixture cover plate, that is, when the fixture moving slider can no longer move forward, under the action of the connecting rod, the spring push rod continues to compress the spring, and the fixture expanding slider moves forward along the third slide rail. At the same time, the three positioning clamping jaws move along the three fourth slide rails. The slide rail moves away from the center of the cylindrical boss of the fixture moving slider. When the workpiece is clamped, the rotation of the lead screw stops, and the workpiece is positioned and clamped. The lead screw is rotated in the opposite direction, and the nut slider moves along the second slide rail groove towards the upper end of the lead screw. Under the action of the connecting rod, the fixture expanding slider moves backward along the third slide rail. At the same time, the three positioning clamping jaws move along the three fourth slide rails towards the center of the cylindrical boss of the fixture moving slider. When the spring push rod contacts the spring limiting nut, the fixture expanding slider, the fixture moving slider, and the positioning clamping jaws move backward along the first slide rail without relative movement under the action of the connecting rod. When the positioning clamping jaws disengage from the workpiece, the rotation of the lead screw stops.

3. The clutch abrasive flow precision polishing equipment according to claim 1, characterized in that: The upper end face of the clutch machining part housing is provided with a sixth slide rail, the right end face is provided with a clutch axial machining hole, the side surface of the outer surface is provided with a clutch radial machining hole, and the bottom surface of the outer surface is provided with an abrasive waste flow outlet. The clutch machining part cover plate is provided with a sixth slide rail groove. The sixth slide rail and the sixth slide rail groove form a sliding pair. The clutch machining part cover plate can move along the sixth slide rail. The clutch machining part housing is fixedly connected to the left support leg and the right support leg. The left support leg and the right support leg are fixedly connected to the base plate. The centrifugal pump is fixedly connected to the base plate. The inlet of the centrifugal pump is connected to the abrasive flow generator through a fitting pipe. The outlet of the centrifugal pump is connected to the clutch radial machining hole and the clutch axial machining hole through fitting pipes respectively. The first switch controls the abrasive flow to the clutch radial machining hole and the clutch axial machining hole. The second switch controls the abrasive flow to the clutch radial machining hole. The third switch controls the abrasive flow to the clutch axial machining hole. The first bearing seat support is fixedly connected to the base plate. On the plate, the first bearing seat is fixedly connected to the first bearing seat support, the second bearing seat support is fixedly connected to the base plate, the second bearing seat is fixedly connected to the second bearing seat support, the clamp housing mates with the first and second bearing seats, the motor is fixedly connected to the base plate, the small pulley is mounted on the motor shaft, the large pulley is mounted on the clamp housing, the motor drives the small pulley, the large pulley, and the clamp part to rotate, the automatic feeding storage device is fixedly connected to the automatic feeding first support leg and the automatic feeding second support leg, the automatic feeding first support leg and the automatic feeding second support leg are fixedly connected to the base plate, the automatic feeding storage device is provided with an automatic feeding stop rod mating hole, the automatic feeding stop rod and the automatic feeding stop rod mating hole form a sliding pair, the automatic feeding motor fixing plate is fixedly connected to the automatic feeding second support leg, the automatic feeding motor is fixedly connected to the automatic feeding motor fixing plate, the cam is mounted on the automatic feeding motor, and the cam and the automatic feeding stop rod mate with each other.

4. The clutch abrasive flow precision polishing equipment according to claim 1, characterized in that: The left end face of the clutch processing part housing is provided with a fixture mating hole, and the inner surface is provided with a clutch processing area. The fixture mating hole is coaxial with the clutch processing area. The radius of the clutch processing area is larger than the radius of the workpiece. The fixture moving slider is installed in the fixture mating hole. When the workpiece is transported to the clutch processing area, the outer surface of the workpiece contacts the clutch processing area. The axis of the workpiece is lower than the axis of the fixture mating hole. Three positioning clamping jaws are outside the inner hole of the workpiece. When the lead screw is rotated in the forward direction, the three positioning clamping jaws move into the inner hole of the workpiece and clamp the workpiece. At this time, the workpiece is coaxial with the fixture mating hole, that is, the outer surface of the workpiece is disengaged from the clutch processing area, ensuring that the fixture part drives the workpiece to rotate smoothly.
