Description

Technical Field

[0001] The utility model relates to a novel eight-station tool magazine indexing mechanism, belonging to the technical field of machinery. Background Art

[0002] The turning tool holders of large-scale automated vertical turning machining centers are large, and their placement in the tool magazine takes up a lot of space. When processing the same workpiece in different processes, it is troublesome to switch tools, which affects the processing efficiency of the workpiece. In addition, the workpieces processed by large-scale vertical turning machining centers are heavier and larger in specifications than those processed by ordinary vertical turning machining centers. It is time-consuming and laborious for the staff to clamp the workpieces. It is not easy to perform multiple processes on the workpiece through one clamping, and the tool positioning accuracy and repeat positioning accuracy are difficult to guarantee during manual tool changing. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a novel eight-station tool magazine indexing mechanism, which can enable the eight-station tool magazine of a vertical turning machining center to achieve fast, stable, reliable and accurate tool change, and can realize arbitrary tool change.

[0004] The utility model solves the technical problem by adopting the following technical solution: a novel eight-station tool magazine indexing mechanism, comprising a dividing plate, a cutter disc, a cam mechanism, a roller, a speed reducer and a motor, wherein the dividing plate is installed above the cutter disc, the dividing plate and the cutter disc are installed coaxially, a plurality of rollers with even intervals are installed at the top edge of the dividing plate, and the rollers are arranged in a circumferential direction on the dividing plate; a motor is arranged above the dividing plate, a driving end of the motor is connected to the cam mechanism through a speed reducer, a cam groove is arranged on the cam mechanism, and one of the rollers is fitted in the cam groove.

[0005] The beneficial effects of the utility model are as follows: the utility model enables the eight-station automatic tool magazine of the vertical turning machining center to have the characteristics of accuracy, speed and arbitrary position change, and the positioning accuracy and repeated positioning accuracy of the tool are guaranteed during the automatic tool changing process, solving the problem of fast and accurate tool changing in the automatic tool changing system of large vertical turning machining, and is easy to operate and practical.

[0011] like Figure 1 As shown in FIG. 2 , a novel eight-station tool magazine indexing mechanism comprises a dividing plate 1, a cutter disc 2, a cam mechanism 3, rollers 4, a reducer 5 and a motor 6. The dividing plate 1 is installed above the cutter disc 2. The dividing plate 1 and the cutter disc 2 are installed coaxially. A plurality of rollers 4 with uniform intervals are installed at the top edge of the dividing plate 1. The rollers 4 are arranged in a circumferential direction on the dividing plate 1. A motor 6 is arranged above the dividing plate 1. The driving end of the motor 6 is connected to the cam mechanism 3 through the reducer 5. The cam mechanism 3 is provided with a cam groove 301, and one of the rollers 4 is fitted in the cam groove 301.

[0012] During use, the motor 6 is used as the power source for the eight-degree indexing of the tool. The motor 6 is connected to the cam mechanism 3 through the reducer 5, so that the cam mechanism 3 generates a rotational motion. The cam mechanism 3 and the roller 4 cooperate with each other through the shape of the cam groove 301. The rotational motion of the cam mechanism 3 drives the roller 4 to roll in the cam groove 301. The main feature of the cam mechanism in transmitting motion is its compact structure, which is most suitable for occasions where the follower is required to make intermittent motion. In addition, the cam mechanism has a simple structure and reliable motion. 1 is coaxially installed with the cutter disc 2, thereby driving the cutter disc 2 to rotate. When the roller 4 in the cam groove 301 completes the stroke of the cam groove 301, it drives the indexing plate 1 to rotate, thereby realizing the indexing of the cutter disc 2. At this time, the next roller 4 adjacent to the roller 4 enters the cam groove 301, and the roller 4 drives the indexing plate 1 to rotate, and transmits this motion to the indexing plate 1. The above process is repeated, so that the eight-degree indexing of the cutter disc 2 can be realized, which effectively solves the problem of accurate, fast and arbitrary replacement of the tool of the large vertical turning machining center.
