[0002] A turntable fixture is a device used to secure and support workpieces and is particularly important in turntable riveting machines. It ensures the workpiece remains stable during the riveting process, preventing machining errors caused by vibration or movement. In conjunction with the turntable, it enables rapid workpiece positioning and replacement, thereby improving production efficiency. Typically designed as a multi-station fixture, it can handle multiple workpieces simultaneously, boosting production capacity. Through precise clamping and positioning, it ensures high workpiece precision during the riveting process. Turntable fixtures optimize workpiece securing and positioning, enhancing stability and production efficiency throughout the riveting process.

[0003] When processing workpieces, different types of parts have different sizes. If they cannot be effectively clamped during processing, the processing accuracy of the workpiece will be affected, affecting the product quality. Therefore, it is necessary to provide a turntable fixture for riveting machine processing to solve the above problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Specific implementation cases:

[0020] like Figure 1 As shown, a turntable fixture for a rotary riveting machine includes a chassis 1, a dividing plate 4 is mounted on the chassis 1, and the dividing plate 4 is driven by a motor. A turntable 3 is mounted on the dividing plate 4, and a workbench 5 is provided on the turntable 3. The workbench 5 is provided with several groups. A clamping body 6 is installed on the workbench 5 for clamping a workpiece. A support base 2 is mounted on the chassis 1, and the support base 2 is provided with several groups. The top of the support base 2 contacts the bottom surface of the turntable 3 to support the turntable 3.

[0021] When the turntable 3 is in motion, the motor drives the indexing plate 4 to drive the turntable 3 mounted thereon to rotate. The support base 2 is mounted on the lower bottom surface of the turntable 3 and is in contact with it. A rotating wheel (not shown in the figure) is mounted on the upper end surface of the support base 2. The arrangement of the rotating wheel enables the turntable 3 to rotate more smoothly. Each support base 2 corresponds to a workbench 5, and the support base 2 is mounted directly below the workbench 5.

[0022] When the riveting press uses the turntable fixture for processing, the workpiece is placed on the clamp body 6 and the clamp body 6 is responsible for clamping. The motor drives the indexing plate 4 to drive the turntable 3 installed on it to rotate, and the worktable 5 is moved to the required working position. Because there are several groups of worktables 5, the workpieces on each worktable 5 can be processed at the same time, which greatly reduces the processing time.

[0023] like Figure 2 As shown, the clamp body 6 includes a threaded rod 65, which is driven by a motor to rotate. A fixing frame 66 is installed above the threaded rod 65, and a placement table (not shown in the figure) is provided on the fixing frame 66 for placing the workpiece. Several groups of connecting rods 64 are rotatably installed on the fixing frame 66, and the connecting rods 64 are evenly distributed along the side surface of the fixing frame 66. A transmission frame 63 is installed below the threaded rod 65, and several groups of connecting rods 64 are rotatably installed on the transmission frame 63. The connecting rods 64 are evenly distributed along the side surface of the transmission frame 63. The surface is evenly distributed, and a rotating shaft 62 is rotatably mounted on the bottom end of the threaded rod 65. The outer ring of the rotating shaft 62 is mounted with a housing 61. A transmission plate 67 is rotatably mounted on the other end of the connecting rod 64. The transmission plate 67 is in the shape of an arc. A limit block (not marked in the figure) is provided on the upper end of the transmission plate 67. The limit block (not marked in the figure) is slidably connected to the housing 61. A slider (not marked in the figure) is provided on the lower end of the transmission plate 67. The slider is slidably connected to the bottom end of the housing 61 to limit the horizontal movement direction of the transmission plate 67.

[0024] The threaded rod 65 has a fixed length and is capable of rotating, and the transmission frame 63 is capable of linearly moving up and down along the threaded rod 65 .

[0025] When the clamp body 6 is in operation, the threaded rod 65 rotates to drive the transmission frame 63 to move upward, and the connecting rod 64, which is rotationally connected to the transmission frame 63 and is also rotationally connected to the transmission plate 67, opens outward, pushing the transmission plate 67 to spread outward. At the same time, the connecting rod 64 connected to the placement table (not marked in the figure) also opens outward. Because the limit block (not marked in the figure) at the upper end of the transmission plate 67 and the slider at the lower end of the transmission plate 67 are all slidably connected to the shell 61 in the same moving direction, the transmission plate 67 only moves linearly outward in a limited direction, that is, several groups of transmission plates 67 spread outward at the same time until the arc surface of the transmission plate 67 fits into the inner wall of the shell 61, which is the transmission plate 6 7 maximum range of motion, then the workpiece is placed on the placement table (not marked in the figure), the threaded rod 65 rotates in the opposite direction, so that the transmission frame 63 moves downward along the threaded rod 65, driving the connecting rod 64 connected to the placement table (not marked in the figure) and the connecting rod 64 connected to the transmission frame 63 to shrink inward, pulling the transmission plate 67 to shrink inward along the direction defined by the limit block (not marked in the figure) and the sliding connection between the slider and the housing 61, and fixing and clamping the workpiece placed on the placement table (not marked in the figure). Because the transmission plates 67 all move towards or away from the same central axis, the transmission plates 67 can always achieve centering and positioning when moving towards or away from the central axis.

[0026] To sum up: the motor drives the indexing plate 4 to rotate the turntable 3 installed thereon, and moves the workbench 5 to the required work position. Since several groups of workbenches 5 are provided, the workpieces on each workbench 5 can be processed together at the same time, which greatly reduces the required processing time; the motor drives the threaded rod 65 to make the transmission frame 63 move up and down on the threaded rod 65, driving the connecting rod 64 rotatingly installed on the fixed frame 66 and the transmission frame 63 to push or pull the transmission plate 67 away from or close to the center axis. The cavity formed between the transmission plates 67 can realize the centering, positioning and clamping of workpieces of different sizes during processing.

[0027] The above description is merely a preferred embodiment of the present application. The scope of protection of the present application is not limited to the above embodiment. All technical solutions based on this concept fall within the scope of protection of the present application. It should be noted that for those skilled in the art, improvements and modifications that do not depart from the principles of the present application should also be considered within the scope of protection of the present application.
