Numerical control squaring machine

Abstract

The invention relates to a numerical control shaper, which comprises a shaper bed, a table feed servomotor, a tool head feed servomotor and a numerical control system, wherein the table feed servomotor and the tool head feed servomotor are connected with the numerical control system; the numerical control shaper also comprises a mainshaft bearing which is fixed on the shaper bed, a hollow spindle which is rotatablely arranged in the inner race of the mainshaft bearing, a big helical gear which is fixed at one end of the hollow spindle, an upper slide block which is arranged on the big helical gear and used for driving a ram to perform reciprocating slide; an approach block is arranged on the hollow spindle, an approach switch corresponding to the approach block is arranged at the mainshaft bearing and the approach switch is electrically connected with the numerical control system. The rotation period of the hollow spindle corresponds to the reciprocating motion period of the ram, the position adjustment for the approach block and the approach switch is not needed when the workpieces with different lengths are processed, thus the control is simple and convenient, and the position for the initiate control over the feed is exact. The whole control system is arranged inside the mainshaft bearing of the shaper and does not influence the aesthetic property of the complete shaper.

Description

technical field [0001] The invention relates to a numerical control planer with a worktable feed control mechanism and a knife rest feed control mechanism. Background technique [0002] In the prior art, when the CNC planer is cutting and processing parts, the cutting feed of the workbench and the tool holder are directly powered by servo motors installed on the beam and the tool holder respectively. When the workbench and the tool holder are cutting feed, another set of cutting feed control mechanism needs to send a signal. After receiving the signal, the CNC system of the machine tool controls the feed of the workbench and the tool holder according to the machining program. The structure of the cutting feed control mechanism of the existing general CNC planer is realized in this way: a T-shaped groove is horizontally arranged on the ram of the planer, and an approaching block whose position can be adjusted along the extending direction of the groove is installed in the gro...

Problems solved by technology

[0004] The purpose of the present invention is to provide a numerically controlled planer capable of quickly and accurately controlling the feeding of the workbench and the knife rest, to overcome the need to adjust the distance between the proximity block and the proximity switch each time the existing numerically controlled planer processes parts of different lengths. Trouble with the distance between them and the problem of inaccurate positioning of the approaching block, so that the control is simple and the cutting feed control of the table and tool holder is accurate
