Description

Technical Field

[0001] The utility model specifically relates to the technical field of rotary clamps, in particular to a rotary clamp assembly for machining multiple workpieces in a machining center. Background Art

[0002] A rotary fixture is a tool widely used in machining, assembly and other fields. It ensures that the workpiece maintains its accurate position during rotation, thereby ensuring machining accuracy and assembly quality. By quickly and accurately adjusting the workpiece angle, it reduces the time for adjusting the workpiece position, thereby improving overall production efficiency.

[0003] At present, the traditional rotary clamp can only clamp one workpiece when clamping the workpiece to be processed. So during operation, the workpiece on the clamp needs to be processed by the machining center. However, after the workpiece is processed, the workpiece in the clamp needs to be frequently replaced, which makes the work efficiency low. Moreover, when the workpiece is frequently replaced, each workpiece needs to be repositioned, which will cause the replacement of the workpiece to take a long time.

[0004] After searching, Chinese patent publication number CN201921353543.6 discloses a multi-station multi-purpose fixture for a machining center; it includes a guide rail and a clamping mechanism, a slide seat is mounted on the guide rail, a shock-absorbing mechanism is arranged above the slide seat, an upper pressing tooth is fixed to the bottom surface of the upper pressing plate, a lower pressing tooth is arranged on the upper surface of the lower pressing plate, a bolt is spirally connected between the upper pressing plate and the lower pressing plate, a clamping seat is fixed above the upper pressing plate, and the clamping mechanisms are respectively arranged on both sides above the clamping seat.

[0005] Although the clamp in the above patent can effectively clamp the workpiece, the clamp in the above patent drives the top block to move by the spring when clamping the workpiece. This may cause the top block to clamp the workpiece unstably through the spring during clamping. In this way, vibration marks will be generated on the surface of the workpiece when processing the workpiece, and the processing accuracy of the workpiece cannot be effectively guaranteed. Utility Model Content

In this structure, the workpiece to be processed is placed on a placement plate, and the workpiece is clamped by the cooperation of a fixed clamp and a movable clamp. During processing, the turntable is driven to revolve through the main shaft. At the same time, the driving gear on the main shaft simultaneously drives multiple driven gears to rotate, so that the placement plate rotates along the arc slide rail on the turntable. In this way, when clamping the clamped workpiece, the movement of the props is effectively reduced, thereby improving the processing efficiency. By setting up multiple placement plates, it is effectively avoided that the machining center is in a stagnant state when the workpiece is replaced during work, so as to avoid affecting the efficiency of the machining center, thereby solving the problems of the above-mentioned background technology.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:
