Description

Technical Field

[0001] This utility model relates to the field of shot peening equipment technology, specifically to a shot peening equipment workpiece rotary table with a swing arm. Background Technology

[0002] Shot peening equipment is a surface treatment device that uses a high-speed stream of shot to impact the surface of a workpiece, thereby improving the workpiece's mechanical properties. It is an indispensable key process equipment in modern manufacturing.

[0003] In the shot peening process, a rotating table is generally used to rotate the workpiece. For example, the invention patent with publication number CN102267102A discloses a sandblasting and shot peening equipment that uses a rotating tray to rotate the entire device. However, this method is only suitable for processing one product. When multiple products need to be processed at the same time, although the entire device can be rotated, the side of the workpiece facing the inside of the rotating tray cannot be processed. This requires multiple manual rotations and restarts of the equipment, which is time-consuming and labor-intensive. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a workpiece rotary table for shot peening equipment with a swing arm, which realizes overall rotation, individual rotation and overall swing, ensuring all-round treatment of the workpiece surface without dead angles, and can process multiple workpieces at one time. It has a simple structure and is easy to control.

[0005] Specifically, this utility model discloses a workpiece rotary table for shot peening equipment with a swing arm, comprising: Swing assembly, including a swing arm; A large turntable assembly includes a mounting base on which a large turntable is rotatably mounted, and the large turntable is connected to a first drive assembly that drives the large turntable to rotate. The small turntable assembly includes multiple small turntables disposed on the large turntable. The multiple small turntables are connected to a second drive assembly, which drives the small turntables to rotate. Each small turntable is provided with a limiting block for limiting the workpiece.

[0006] The advantages of adopting the above technical solution are that the whole device has three rotating components: swing, large turntable rotation and small turntable rotation, which can meet the processing of single workpieces and multiple workpieces. The surface of the workpiece can make good contact with the shot blasting equipment, ensuring the surface treatment quality. At the same time, no manual adjustment is required, thus improving the surface treatment efficiency.

[0007] Furthermore, the small turntable is connected to a rotating shaft, and the rotating shaft is connected to a drive pulley. The second drive assembly includes a second drive motor, a synchronous belt, and a drive pulley. The drive pulley is connected to the output end of the second drive motor, and the synchronous belt connects the drive pulley and the drive pulley.

[0008] The advantage of adopting the above technical solution is that, by setting up the drive pulley and synchronous belt, only one drive motor is needed to realize the rotation control of all small turntables, which has high control precision, makes all workpieces rotate together, and ensures the surface treatment accuracy of all surfaces of the workpieces.

[0009] Furthermore, a tension pulley is provided between the drive pulleys, and a tension shaft is connected to the tension pulley. The tension shaft is fixed to a tension plate, and strip holes are provided on both sides of the tension plate. The strip holes are fixed to the large turntable assembly by locking components.

[0010] The advantage of adopting the above technical solution is that the setting of the tension pulley ensures the tension of the synchronous belt, ensures the synchronous rotation of all small turntables, and ensures driving accuracy and synchronous operation.

[0011] Furthermore, a protective plate is provided on the upper side of the drive pulley and the tension pulley.

[0012] The advantage of adopting the above technical solution is that the protective plate plays a protective role, preventing the material sprayed by the shot blasting equipment from affecting the rotation of the drive pulley and tension pulley, and extending the service life of the drive pulley and tension pulley.

[0013] Furthermore, the first drive assembly includes: a connecting seat, a gear ring, a first drive motor, and a drive gear. The drive gear is connected to the output end of the first drive motor. The connecting seat is fixedly connected to the large turntable and its bottom is rotatably mounted on the mounting base.

[0014] The advantages of adopting the above technical solution are that the connecting seat plays a supporting and connecting role, and the first drive motor drives the gear ring to rotate, which in turn drives the large turntable to rotate. The rotation is smooth, easy to control, and the structure is simple.

[0015] Furthermore, the upper surface of both the large turntable and the small turntable is provided with multiple grooves along the diametrical direction.

[0016] The advantage of adopting the above technical solution is that the multiple grooves are used to place fixing nuts to fix the workpiece. Since the grooves are set along the diameter, they are suitable for workpieces of different sizes, thus improving the practicality of the entire turntable.

[0017] Furthermore, the swing assembly is also provided with a limit fixing component, including: a fixing frame, a cylinder, an extension head, a positioning plate and a base plate for fixing the positioning plate. The fixing frame is fixed on the mounting base, the cylinder is installed with the fixing frame, the extension head is connected to the output end of the cylinder, the cylinder extends out, and the extension head extends into the positioning groove on the positioning plate.

[0018] The advantage of adopting the above technical solution is that when the swing arm rotates to the processing position, the protruding head extends into the positioning plate and is fixed, so that the entire swing arm position is fixed, and then the large and small turntables rotate, ensuring stability during use.

[0019] Furthermore, a slip ring assembly is installed at the bottom of the second drive motor, including a slip ring, an upper mounting bracket, and a bottom connecting plate. The upper mounting bracket is connected to the large turntable assembly, the bottom connecting plate is fixed to the mounting base, and the slip ring is connected to the upper mounting bracket and the bottom connecting plate for connecting the second drive motor and an external power source.

[0020] The advantage of adopting the above technical solution is that, since the second drive motor rotates with the large turntable, the installation slip ring plays a role in the transfer, ensuring that the motor wiring does not get tangled and making installation convenient.

[0021] Furthermore, the mounting base is equipped with an air jet nozzle, which is connected to an air source and is positioned toward the large turntable assembly.

[0022] The advantages of adopting the above technical solution are that the air jet nozzle is used to clean the material sprayed out by the shot peening equipment, ensuring the normal operation of the large and small turntables. At the same time, the cleaned workpieces do not need to be cleaned again, thus improving processing efficiency.

[0023] Furthermore, the swing arm is connected to a third driving device, including a third driving component and a driving shaft. The swing arm is fixedly connected to the driving shaft, and a rotating seat is provided at the bottom of the driving shaft. The third driving component drives the driving shaft to rotate.

[0024] The advantage of adopting the above technical solution is that the third driving component drives the swing arm to swing, and the swing arm can stop at the required position according to the use needs, thus meeting a variety of use needs. Attached Figure Description
