Description

Technical Field

[0001] The invention mainly relates to the technical field of cradle turntables, and in particular to a swing arm control system of a cradle turntable. Background Art

[0002] A cradle turntable is a multi-axis rotary platform device used in industrial production, usually for processing and assembling complex parts or products. The cradle five-axis turntable can rotate, tilt and swivel in multiple directions, allowing for more flexible processing and assembly operations. It is widely used in aerospace, automotive manufacturing, mechanical processing and other fields to improve production efficiency and product quality.

[0003] The cradle turntable usually clamps and fixes the side of the workpiece through multiple clamps, but the cradle turntable will rotate to adjust the angle during the workpiece processing. When the cradle turntable rotates too much, the workpiece with a smoother clamping surface will slip or even fall off the cradle turntable, which will affect the accuracy of the workpiece processing. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. It mainly provides a swing arm control system of a cradle turntable, which is used to solve the technical problem mentioned in the above background technology that the cradle turntable cannot ensure stable clamping of workpieces with smooth clamping surfaces when rotating, resulting in affected accuracy during workpiece processing.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: A swing arm control system for a cradle turntable comprises a support seat, a cradle swing arm is arranged on the support seat, a rotating base is arranged on the cradle swing arm, a clamping assembly for clamping and fixing a workpiece is arranged on the rotating base, and the clamping assembly can adaptively press down and fix the top of the workpiece, a brush for cleaning the top of the rotating base is arranged on the support seat, a first motor is arranged on one side of the support seat, and a transmission assembly is arranged between the first motor, the cradle swing arm and the brush.

[0006] Preferably, the transmission assembly includes a rotating shaft, the rotating shaft is fixedly mounted on the output end of the first motor, and the rotating shaft is rotatably connected inside the support seat.

[0007] Preferably, a cradle swing arm is provided at one end of the rotating shaft away from the first motor, and the cradle swing arm is rotatably connected to the support seat.

[0008] Preferably, a waste recovery groove is provided on the support seat, a rotating rod is rotatably connected above the waste recovery groove, and a pulley group is sleeved between the rotating rod and the rotating shaft.

[0009] Preferably, a rotating plate is fixedly mounted on one end of the rotating rod, a second motor is arranged on the rotating plate, and a brush is arranged at an output end of the second motor.

[0010] Preferably, the clamping assembly comprises a multi-jaw chuck, the multi-jaw chuck is arranged above the rotating base, and the multi-jaw chuck is provided with balls.

[0011] Preferably, a clamping block is provided on the multi-jaw chuck, a sliding block is provided on the clamping block, and the sliding block is slidably connected to the multi-jaw chuck.

[0012] Preferably, a telescopic block is provided on the clamping block, a top plate is provided on the telescopic block, and a limiting block is provided on the top plate.

[0013] Preferably, an elastic sheet is provided on the telescopic block, and a connecting rod is provided between the elastic sheet and the limiting block.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: ball bearings are provided on the multi-jaw chuck, and when the workpiece is above the multi-jaw chuck, it is above the ball bearings. When the multiple clamping blocks on the multi-jaw chuck move inward synchronously, the clamping blocks push the workpiece, and the workpiece can be easily pushed to move in cooperation with the ball bearings. This can prevent the workpiece from being too heavy and causing the clamping blocks to be unable to push the workpiece. At the same time, it can also reduce the friction between the workpiece and the surface of the multi-jaw chuck, preventing the bottom of the workpiece from being uneven.

[0015] There is only a telescopic block in red above the clamping block. When the upper surface of the workpiece is processed, there is no need to rotate the cradle swing arm. In this way, the workpiece can be clamped and fixed only by supporting the side of the workpiece with the clamping block. When the side of the workpiece needs to be processed, the telescopic block is lowered, and the elastic sheet on the inside of the telescopic block shrinks when it is against the workpiece. The top plate is lowered through the connecting rod. At this time, the top plate is attached to the upper surface of the workpiece, so that the workpiece is supported by the top plate, and the top plate adapts to the thickness of the workpiece to adjust and fit to the upper surface of the workpiece. In this way, when processing the side of the workpiece, the workpiece can be kept fixed at all times when adjusting the cradle swing arm, and there is no need to manually judge the thickness of the workpiece to adjust the top plate, which is convenient to use.

[0016] When the top of the workpiece is processed and the side of the workpiece needs to be processed, the first motor is started, and the first motor drives the cradle swing arm to rotate and adjust the angle through the transmission component. At the same time, the first motor drives the brush on the side to rotate through the transmission component. The brush corresponding to the side to which the workpiece rotates will be rotated to fit the multi-jaw chuck and the surface of the workpiece, and the multi-jaw chuck is cleaned by the brush, which can reduce the impact of waste chips generated by the workpiece processing on the subsequent processing of the workpiece.

[0023] The specific operation process of the present invention is as follows: place the workpiece above the clamping assembly, clamp and fix the workpiece by the clamping assembly, and then process the upper surface of the workpiece by the processing device. When the side of the workpiece needs to be processed, start the first motor 6, and the first motor 6 drives the cradle swing arm 2 to rotate through the transmission assembly. At the same time, the first motor 6 will drive the brush 12 on one side of the rotation direction of the cradle swing arm 2 to rotate through the transmission assembly. The brush 12 rotates to fit the clamping assembly and the workpiece, and the surface of the clamping assembly is cleaned by the rotation of the brush 12. The rotating base 3 can be rotated to drive the upper workpiece to rotate and change the surface for processing.

[0024] Please refer to Figure 4 The transmission assembly includes a rotating shaft 7, which is fixedly mounted at the output end of the first motor 6 and rotatably connected to the inside of the support base 1. A cradle swing arm 2 is provided at one end of the rotating shaft 7 away from the first motor 6, and the cradle swing arm 2 is rotatably connected to the support base 1.

[0025] The first motor 6 is started, and the first motor 6 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the cradle swing arm 2 to rotate. The angle of the workpiece fixed above is adjusted by rotating the cradle swing arm 2 to achieve processing of the side of the workpiece.

[0026] Please refer to Figure 4 A waste recovery trough 4 is provided on the support seat 1, a rotating rod 8 is rotatably connected above the waste recovery trough 4, a pulley group 9 is sleeved between the rotating rod 8 and the rotating shaft 7, a rotating plate 10 is fixedly installed at one end of the rotating rod 8, a second motor 11 is provided on the rotating plate 10, and a brush 12 is provided at the output end of the second motor 11.

[0027] The rotating shaft 7 rotates through the pulley group 9 to drive the rotating rod 8 to rotate, the rotating rod 8 rotates to drive the rotating plate 10 to rotate, the rotating plate 10 rotates to drive the brush 12 to rotate and fit the clamping assembly above the rotating base 3 and the workpiece, the second motor 11 is started, the second motor 11 drives the brush 12 to rotate, and the brush 12 sweeps the waste chips generated by the workpiece processing into the waste recovery tank 4 below for recycling.

[0028] Please refer to Figure 5 and Figure 6The clamping assembly includes a multi-jaw chuck 5, which is arranged above the rotating base 3. A ball 13 is arranged on the multi-jaw chuck 5. A clamping block 14 is arranged on the multi-jaw chuck 5. A sliding block 15 is arranged on the clamping block 14. The sliding block 15 is slidably connected with the multi-jaw chuck 5. A telescopic block 16 is arranged on the clamping block 14. A top plate 17 is arranged on the telescopic block 16. A limiting block 20 is arranged on the top plate 17. An elastic sheet 18 is arranged on the telescopic block 16. A connecting rod 19 is arranged between the elastic sheet 18 and the limiting block 20.

[0029] The multi-jaw chuck 5 drives the multiple clamping blocks 14 to move inward synchronously. The clamping blocks 14 that first contact the workpiece will push the workpiece to move in the opposite direction. The ball 13 reduces the friction between the workpiece and the multi-jaw chuck 5. When the multiple clamping blocks 14 are in contact with the workpiece, the workpiece is clamped and fixed. When the workpiece needs to be rotated for processing on the side, the clamping blocks 14 are energized, the telescopic blocks 16 begin to descend and shrink, and the elastic sheet 18 on the telescopic blocks 16 begins to contact the workpiece, and the contact surface between the elastic sheet 18 and the workpiece is an inclined surface. As the telescopic block 16 continues to descend, the elastic sheet 18 is pressed by the workpiece. When the uppermost part of the elastic sheet 18 is compressed and contracted by the workpiece, the elastic sheet 18 drives the upper top plate 17 to rotate 90° and fit the upper part of the workpiece through the connecting rod 19 and the limiting block 20, and the top plate 17 presses down and fixes the workpiece. The sliding block 15 is used to limit the linear forward and backward movement of the clamping block 14. The elastic sheet 18 is made of elastic metal and will rebound and stretch when it is not compressed. In this way, when the elastic sheet 18 is not compressed, the top plate 17 and the telescopic block 16 are in a straight line, preventing the top plate 17 from being in a vertical state with the telescopic block 16 at the beginning and affecting the processing of the workpiece.

[0030] The control system is operated to energize the first motor 6, which drives the cradle swing arm 2 to rotate through the transmission component, and the first motor 6 drives the rotating plates 10 on both sides of the cradle swing arm 2 to rotate through the transmission component. At the same time, the built-in motor of the cradle swing arm 2 is energized, and the built-in motor of the cradle swing arm 2 drives the rotating base 3 to rotate. The second motor 11 is energized to drive the second motor 11 to work, and the second motor 11 drives the brush 12 to rotate.
