Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is a top view of the present invention.

In the figure: the positioning device comprises a positioning column 1, a servo motor 2, a screw rod 3, a nut 4, an upper tool apron 5, a tool rest 6, a lower tool apron 7 and a bearing 8.

Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

Referring to fig. 1-2, the tool holder apparatus disclosed in the present invention is suitable for up-and-down adjustment of various tool holder seats with tool holders.

The adjustable knife rest device for the pole piece splitting machine comprises a knife rest 6 for supporting a cutting tool, wherein the cutting tool is installed in the center of the knife rest, and knife rest seats are symmetrically arranged at two ends of the knife rest. The tool rest seat comprises an upper tool apron 5 and a lower tool apron 7; a lifting adjusting component and a guiding component are arranged between the upper tool apron and the lower tool apron; the lifting adjusting component realizes the up-and-down movement of the upper tool apron; the direction of the upper tool apron in the up-and-down moving process is realized by the guide assembly.

In this embodiment, the lifting adjustment assembly includes a screw 3 and a nut 4; the middle part of the upper tool apron is provided with at least one threaded hole, and in the embodiment, two threaded holes are arranged in parallel on the upper tool apron along the width direction of the upper tool apron. A nut 4 is fixedly connected to the upper tool apron at the position of the upper port of the threaded hole, and a screw rod 3 is inserted in the threaded hole; the screw rod is movably sleeved with the nut through threads. An inner groove is formed in the middle of the lower cutter holder, and a bearing 8 is embedded in the inner groove; the lower end of the screw 4 is in running fit with a bearing 8. The top end of the screw rod is provided with a servo motor 2; the servo motor is connected with and controlled by the main control machine of the splitting machine. The servo motors on the tool rest seats at the two ends of the tool rest are controlled by the main control machine to rotate simultaneously, the rotating speed and the rotating direction of the servo motors are the same, the stability of the lifting of the upper tool rest is guaranteed, and the tool inclination caused by different heights of the two ends is effectively avoided.
