Numerical control planer tool fine adjustment mechanism

Abstract

The invention discloses a numerical control planer tool fine adjustment mechanism and belongs to the technical field of planers. By arranging the tool adjusting assembly, when the position of the planer tool deviates, an arranged adjusting gear can rotate to drive a rotating plate to rotate, so that the position of a tool nose of the planer tool is adjusted, and when the planer tool deviates leftwards and rightwards, the adjusting gear and an adjusting gear ring can be matched to rotate the rotating plate, so that the left and right positions of the planer tool are rapidly adjusted; when the planer tool is abraded to cause deviation of the height position, the planer tool can be squeezed downwards by slightly loosening the tightening bolt for fixing the planer tool and rotating the adjusting bolt, and rapid adjustment of the planer tool in the height direction is achieved.

Description

Technical Field

[0001] The invention belongs to the technical field of planers, and in particular relates to a tool fine-tuning mechanism for a numerically controlled planer. Background Art

[0002] Gantry planers are mainly used for planing large workpieces. They can also clamp multiple parts on the workbench for simultaneous processing. They are the mother machines of industry. The workbench of the gantry planer carries the workpiece through a portal frame for linear reciprocating motion. The idle stroke speed is greater than the working stroke speed. Traditional gantry planers can only plan workpieces in one direction. When the workbench is in reciprocating motion, half of the working time is the idle stroke of the workbench returning, and planing processing cannot be performed. This affects the working efficiency of the machine tool and greatly reduces the working efficiency.

[0003] The existing gantry planer capable of bidirectional planing has the following shortcomings: the forward planer and the reverse planer are fixedly connected to the piston rod of the cylinder. When in use, the forward planer and the reverse planer are subjected to a large impact force, resulting in the displacement of the planer tip position after working for a period of time, which requires manual adjustment. The traditional adjustment method is through marking and manual adjustment by knocking with a copper rod. However, manual knocking often results in excessive or inadequate knocking, resulting in low adjustment efficiency, which affects the overall processing efficiency. Summary of the invention

[0004] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides a tool fine-tuning mechanism for a numerically controlled planer.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: a CNC planer tool fine-tuning mechanism, comprising a mounting plate connected to a bed, a group of knife adjustment components are arranged on the front and rear end surfaces of the mounting plate, the knife adjustment component comprises a telescopic cylinder and a sliding plate, the sliding plate is slidably connected to the lower end of the mounting plate, the telescopic cylinder is arranged on the mounting plate on the upper side of the sliding plate, and is fixedly connected to the mounting plate, the extended end of the telescopic cylinder is fixedly connected to the top of the sliding plate, a rotating plate is arranged on the sliding plate, the rotating plate is rotatably connected to the sliding plate, an adjustment gear ring is arranged on the top of the rotating plate, an adjustment gear is arranged on the sliding plate on the upper side of the rotating plate, the adjustment gear is meshed with the adjustment gear ring, a plurality of groups of mounting holes are arranged on the adjustment plate, a knife mounting housing is arranged on the mounting hole, a positioning pin matched with the mounting hole is arranged on one end of the knife mounting housing close to the rotating plate, the knife mounting housing is connected by being embedded in the mounting hole through the positioning pin, and the knife mounting housing can be fastened to the rotating plate by bolts.

[0006] Preferably, the tool holder may have a plurality of screw holes distributed longitudinally on the remaining end surface, and tightening bolts for tightening the planer tool are installed in the screw holes.

[0007] Preferably, an adjustment bolt for adjusting the height of the planer is provided on the top of the tool mounting housing.

[0008] Preferably, the rotational connection between the rotating plate and the sliding plate is in a pre-tightened state. When the adjusting gear is not rotated to adjust it, the rotating plate will not rotate by itself. Similarly, the adjusting gear is in a pre-tightened state with the sliding plate.

[0009] Preferably, an adjustment hole is provided on the adjustment gear, and the adjustment hole is any one of a hexagonal, cross, flat or plum blossom structure.

[0010] The beneficial effects of the present invention are as follows: by setting up a knife adjusting assembly, when the planer knife is offset in position, the setting adjusting gear can be used to drive the rotating plate to rotate, thereby adjusting the position of the planer knife tip; when the planer knife is offset to the left or right, the adjusting gear and the adjusting gear ring can be used to rotate the rotating plate to achieve rapid adjustment of the left and right positions of the planer knife; when the planer knife is worn and the height position deviates, the planer knife can be squeezed downward by slightly loosening the tightening bolts that fix the planer knife and rotating the adjusting bolts, thereby achieving rapid adjustment of the height direction of the planer knife.
