Problems solved by technology

[0003] The inner holes of woodworking tools are installed on the mechanical shaft with positive 2 to 3 wires. Due to the gap between the inner hole and the mechanical shaft, the concentricity is not good.
As a result, only two of the four-edged and six-edged blades are being processed, the service life of the tool is short, and the workpiece is not smooth and has ripples; the machine vibrates greatly, which affects the dynamic balance. Later, it is changed to a tapered shaft, which is too laborious for loading and unloading. The tool and the mechanical shaft often Hugged to death, can't take it out

Embodiment 1

[0031] Such as figure 1 As shown, the concentric installation process of the inner hole of the woodworking tool is used to install the tool shaft 1 with the inner hole 11, and at least four blades 2 concentrically installed outside the tool shaft 1 in turn, so that all the blades 2 after the installation are completed. Can be concentric with the inner hole 11 of the tool shaft.

[0032] In a specific operation process, the blade 2 is set to include two end blades 21, and at least two sandwich blades 22 between the two end blades, the thickness of the end blade 21 is set to be m, and the sandwich blade 22 The thickness of n is n, and the thickness of each end blade 21 is guaranteed to be greater than the thickness of any sandwich blade 22 when the tool is installed, i.e. m>n. The main purpose of this design is to drive the sandwich blades synchronously with the help of the gravity of the two end blades during inflatable installation. Generally speaking, the best implementation...

Embodiment 2

[0035] See details figure 2 As shown, a better embodiment is that each flexible pressure equalizing air pipe 212 is located at the outer edge of the end blade with an electromagnetic deflation valve 5, and the electromagnetic deflation valve 5 and the inflation nozzle 6 are connected to the inflation device 7 to realize inflation. And deflate; when the inflation nozzle is inflated, the gas entering the flexible pressure equalizing air pipe flows from the center position of the end blade to both sides respectively, so that the flexible pressure equalizing air pipe expands rapidly, thereby adjusting the two end blades and clamped on it The inner sandwich blade is concentric. The use of the electromagnetic deflation valve 5 is mainly to realize automatic pressure relief (i.e. deflation) after the pressure equalizing air pipe is used up, so that it is convenient to inflate directly to the center when it is used next time, so as to improve work efficiency.

Embodiment 3

[0037] The difference from Embodiments 1 and 2 is that each flexible pressure equalizing air pipe 212 is provided with at least one pair of counterweight structures 4 at a symmetrical position near the outer edge of the end blade, and the counterweight structure is such that the center of gravity faces toward the outer edge of the end blade. Inclined conical structure or polygonal pyramid structure, the use of these conical structures or polygonal pyramid structures, on the one hand, is to assist the inflation of the uniform pressure trachea, and on the other hand, to provide heavier equal pressure pressure and improve the concentric effect .

[0038] A preferred embodiment is that at the bottom of any one of the flexible pressure equalizing air pipes 212, use an adhesive to bond it in its corresponding inflation groove 211, or define the expansion channel of the flexible pressure equalizing air pipe 212 through an annular clamp, and the annular The length of the hoop is not l...

Abstract

The invention provides a concentric installation process for an inner bore of a woodworking tool. The concentric installation process is used for installing a tool shaft provided with the inner bore and sequentially and concentrically installing at least four cutting edges outside the tool shaft so that all installed cutting edges are concentric to the inner bore of the tool shaft; a mounting anddismounting assisting concentric device for the inner bore of the woodworking tool comprises an air charging mouth and air charging grooves, wherein the air charging mouth is arranged inside the innerbore of the woodworking tool shaft; the air charging grooves are formed in the diameter direction of the cutting edges arranged at the end part of the woodworking tool; the air charging mouth is connected with two uniform-pressure air pipes through a three-way pipe; and the two uniform-pressure air pipes are symmetrically fixedly arranged inside the air charging grooves. The concentric installation process and the mounting and dismounting assisting concentric device for the inner bore of the woodworking tool realize consistent concentricity in machining and use of a cutter; the cutter is goodin dynamic balance; and the concentricity and the machining precision can also be guaranteed even when a mechanical shaft is slightly abraded.

Description

technical field [0001] The invention relates to the technical field of woodworking tools, in particular to a concentric air pressure device for loading and unloading the inner holes of woodworking tools. Background technique [0002] In recent years, the tooth fixing structure of woodworking knives has gradually replaced the original welded structure with a clip-on structure. The clip-type tooth fixing structure can greatly improve the overall service life and production efficiency of the tool. Existing woodworking milling cutters with detachable blades are generally composed of a cutter body, cutting teeth, pressing blocks and tightening screws. A concave tooth fixing base is provided on the outer edge of the cutter, and the cutting teeth and pressing blocks are placed In the cutter tooth fixing base, screw mounting holes are provided on the pressing block and the cutter tooth fixing base, and the pressing block is fixed and the cutting blade is clamped by tightening the sc...
