Description

Technical Field

[0001] The invention relates to the technical field of coupling processing equipment, in particular to a positioning device for processing a ball cage coupling. Background Art

[0002] The ball cage coupling, also known as the ball cage universal coupling, constant velocity coupling or ball cage synchronous universal coupling, is a mechanical transmission device that realizes the connection and torque transmission of two shafts at different angles through a specific structure. The ball cage coupling is mainly composed of a jacket (ball cage outer ring), a star wheel (star-shaped inner ring), a cage and steel balls. The center of the force-transmitting steel balls is located in the plane passing through the center of the coupling, and is installed in the raceway composed of the outer spherical ring and the outer spherical groove of the star-shaped inner ring. The center of the two spheres coincides with the center of the universal coupling. In order to ensure that the centers of all steel balls are on the bisector of the angle between the two axis axes, the steel balls are installed in the window of the cage.

[0003] Due to the requirement of machining accuracy, the ball cage coupling needs to be limited during machining. However, traditional limit devices cannot meet the positioning requirements of large batches, which will affect the machining efficiency. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a positioning device for ball cage coupling processing, which solves the problem that traditional limiting equipment cannot meet the positioning requirements of large batches and will affect processing efficiency.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a positioning device for ball cage coupling processing, comprising a processing box and a servo motor, wherein the interior of the processing box is provided with a locking mechanism, a cleaning mechanism and a driving mechanism from top to bottom in sequence, wherein the locking mechanism comprises a plurality of adjusting screws, wherein one end of the plurality of adjusting screws close to the inner wall of the processing box is rotatably connected to the inner wall of the processing box through a bearing, wherein the outer surfaces of the plurality of adjusting screws have a plurality of threads of equal length, and the rotation directions of two adjacent threads are opposite, and the outer surfaces of the plurality of threads are threadedly sleeved with a limit seat body, and the cleaning mechanism comprises a mounting rod, wherein the top of the mounting rod is fixedly connected to the inner top of the processing box, and the outer surface of the mounting rod is rotatably connected to a plurality of connecting rods, and one end of the plurality of connecting rods is away from the mounting rod The gears are fixedly connected with a transmission gear, and the transmission gears are respectively meshed with a plurality of adjusting gears. The outer surfaces of the plurality of connecting rods are fixedly sleeved with an adjusting roller body, and the outer surfaces of the plurality of adjusting roller bodies are surrounded by adjusting slots, and the adjusting slots extend along the direction of the connecting rods. The interiors of the plurality of adjusting slots are slidably engaged with mounting shafts, and the tops of the mounting shafts extend to the top of the adjusting roller body and are fixedly connected with a cleaning brush. The driving mechanism includes a center rod and a driving frame, the bottom of the center rod is fixedly connected to the driving end of the servo motor, the outer surface of the center rod is fixedly connected with a plurality of driving arc plates, and the ends of the plurality of driving arc plates away from the center rod are fixedly connected to the inner side wall of the driving frame, and the top of the driving frame is fixedly connected with a plurality of driving teeth, and the plurality of driving teeth are distributed in a ring array.

[0006] Preferably, a plurality of limiting frames are fixedly connected to the outer surface of the mounting rod, the plurality of limiting frames are arranged in parallel with the plurality of connecting rods, and the plurality of mounting shafts are respectively limited by the plurality of limiting frames.

[0007] Preferably, the outer surface teeth of the adjusting gear are retractable adjusting teeth.

[0008] Preferably, a plurality of limiting slots are provided on the top of the processing box.

[0009] Working principle: when in use, place the coupling to be processed between two adjacent limit seat bodies, start the servo motor, and the driving end of the servo motor drives the driving arc plate to drive the driving frame to rotate. At this time, the teeth on the outer surface of the transmission gear are in an extended state, and the driving frame drives the transmission gear to rotate through the driving teeth on its upper surface. Since the transmission gear and the adjusting gear are meshingly connected, the adjusting gear will be driven at this time to rotate with the adjusting screw. Since the two adjacent sections of the multiple threads on the outer surface of the adjusting screw have opposite rotation directions, the movement directions of the fixed thread sleeves between the limit seat bodies on the outer surfaces of the two adjacent sections of the threads will be opposite, and the components to be processed will be limited. The present invention can limit multiple components at the same time, and the driving state can be changed by adjusting the state of the teeth on the outer surface of the adjusting gear, so that components of different sizes can be processed. Limiting improves the applicability of the equipment. During the processing, the teeth on the outside of the adjusting gear are adjusted to a retracted state, and the servo motor always maintains a driving state. At this time, the rotation of multiple mounting rods will drive multiple adjusting rollers to rotate. Since the mounting shaft that is slidably connected to the inside of the adjusting slot is slidingly limited by a limiting frame, and the adjusting slot extends along the direction of the connecting rod, the mounting shaft will drive the cleaning brush to continuously move back and forth along the direction of the limiting frame, and will continuously brush the upper components as the processing proceeds. After the processing is completed, the adjusting gear is adjusted to a driving state, and the movement of the adjusting screw can further clean the upper components, which is convenient for subsequent use. In addition, during the processing, the rotation of the driving arc plate generates a downward negative pressure, which will firmly concentrate the debris generated by the processing below the driving mechanism to keep the processed components clean.

[0010] (III) Beneficial effects The present invention provides a positioning device for processing a ball cage coupling, which has the following beneficial effects: 1. The positioning device for processing the ball cage coupling has a threaded sleeve and a limit seat body disposed on the outer surface of two adjacent threaded sections, and the moving directions between the limit seats are opposite, thereby limiting the components to be processed. The present invention can limit multiple components at the same time, and can change the driving state by adjusting the state of the teeth on the outer surface of the gear, thereby limiting components of different sizes, thereby improving the applicability of the equipment.

[0011] 2. The positioning device for ball cage coupling processing, the installation shaft will drive the cleaning brush to move back and forth continuously along the direction of the limit frame, and will continuously brush the upper components as the processing progresses. After the processing is completed, adjust the adjustment gear to the driving state, and cooperate with the movement of the adjusting screw to further clean the upper components, which is convenient for subsequent use. In the process of processing, the rotation of the driving arc plate generates downward negative pressure, which will firmly concentrate the debris generated by the processing under the driving mechanism to keep the processed components clean.
