Description

Technical Field

[0001] The utility model relates to the technical field of mechanical numerical control, in particular to a four-station turntable indexing device. Background Art

[0002] The conventional indexing mechanism is a cam divider. Generally, cam dividers are relatively expensive and complicated to install. Currently, the most commonly used indexing mechanism uses cam dividers as its components. The cam divider relies on the coaxial cam on the input shaft and the indexing plate with evenly distributed needle bearings on the output shaft to mesh vertically without gaps. The curved segment of the cam profile surface drives the needle bearings on the indexing plate to drive the indexing plate to rotate, and the straight segment makes the indexing plate stationary and self-locking in position.

[0003] The prior art also has the following defects during use:

[0004] Most of the existing dividing mechanisms are cam dividers. However, because the cam dividers themselves are easy to wear, in order to maintain product quality, the cam dividers must be inspected regularly to prevent the loss of accuracy due to wear. Without lifting, the precise positioning and rotation of the workpiece cannot be achieved, which is not conducive to the work.

[0005] In view of this, we propose a four-station turntable indexing device to solve the existing problems. Utility Model Content

[0008] Preferably, the heating and shaping mechanism includes a column, the lower end of the column is connected to a rotating shaft support seat, the lower end of the rotating shaft support seat is installed with a rotating shaft support base plate, the upper end of the column is installed with a lifting cylinder mounting block, the lifting cylinder is installed on the lifting cylinder mounting block, the lifting cylinder is connected to a large table plate, a small table plate is installed at the lower end of the large table plate, and a heating rod is installed between the large table plate and the small table plate.

[0009] Preferably, a lifting mechanism is installed at the lower end of the bottom mounting plate, and a small lifting platform mechanism is connected to the upper end of the lifting mechanism.

[0010] Preferably, a servo motor is installed at the lower end of the bottom mounting plate, and the servo motor is upwardly connected to a hollow rotating platform.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model arranges a four-station turntable in the indexing mechanism. During the rotation process, the four stations work simultaneously without interfering with each other. After the last station completes the action, a signal is sent, and the servo motor rotates 90 degrees on one side of the indexing. Compared with the cam divider of the ordinary indexing mechanism, the four-station divider is simple to install and saves cost. In addition, a lifting mechanism is arranged, which can well ensure the accurate positioning and rotation of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
