Abstract
The invention provides a structure of a movable seat. The structure is erected on the rotating shaft of a main shaft, a plurality of slideways are arranged on the rotating shaft, the movable seat and a movable saw blade group are erected on the rotating shaft and positioned on the rotating shaft through an inner ring, the movable seat is connected with the movable saw blade group, the movable seat is provided with an outer ring and an inner ring, a plurality of groups of rolling components are arranged in the inner ring and lean in the slideways of the rotating shaft, and the inner ring is not in contact with the rotating shaft; accordingly, the rolling components in the inner ring can roll in the slideways of the rotating shaft, so that the movable seat drives the movable saw blade groupto be displaced, thereby achieving the purposes of easy maintenance of the rolling components, no friction loss, easy dust removal and accurate positioning of the movable saw blade group.
Description
[technical field]
The present invention relates to a kind of structure of movable seat, it is relevant with carpenter's machine, especially the saw blade that refers to carpenter's machine moves seat and can move in rotating shaft (main shaft) is smooth and easy, dust is easily got rid of, the inner ring that moves seat does not contact, does not have wearing and tearing with rotating shaft, and need not to use copper spare goods, maintenance reaches a kind of structure of movable seat that improves service life easily.
[background technology]
The main shaft of tradition carpenter machine sets up saw blade, with cutting timber, because not applied, do not use single saw blade, so the main shaft of carpenter's machine can set up the saw blade of many groups, make timber can once cut multi-disc, the saw blade of general many groups, the distance between saw blade and the saw blade can adjust outer reaching outside the location in advance, and one or more movably saw blades are still arranged, with cutting demand in response to the timber periphery, saw blade movably can also be done dodging and the setting of different size of timber wood knot, to reach the maximum rate of drawing materials;
As shown in Figure 1, 2, 3, it is the main shaft 10 of carpenter's machine, one rotating shaft 11 is arranged on the main shaft 10, set up several saw blades 12 on the rotating shaft 11, the inner ring of many group saw blades 12 has a locating ring 13, locating ring 13 is positioned on the rotating shaft 11, there is the oil pressure expanding mechanism can replace locating ring 13 in the saw blade 12 in this rotating shaft 11, locating ring 13 and saw blade 12 are positioned on the rotating shaft 11, and unclamp in the rotating shaft 11 of can not spinning, the board that perhaps has is that the locating ring 13 that will organize saw blade 12 directly is locked on the rotating shaft 11 more; The other end of rotating shaft 11 also sets up one or more removable saw blades 16, removable saw blade 16 is connected to one and moves seat 17 adjacent sides, this removable saw blade 16 and mobile seat 17 connect jointly establishes a locating ring 161, locating ring 161 mainly is a copper product, inner ring has several grooves, the projection 15 that can be stuck in rotating shaft 11 is to locate, and this locating ring 161 contacts with rotating shaft 11 surfaces, this removable saw blade 16 can be by the passing of moving seat 17 and displacement, mobile seat 17 is articulated with this locating ring 161 again, and (moving seat 17 has one to push away handle 171, pushing away has bearing 172 and locating ring 161 to be articulated in the handle 171), push away handle 171 and can promote to move seat 17, push away handle 171 tops and connect and establish a body of rod 173, have length adjuster can know the distance that the body of rod 173 promotes on carpenter's machine;
Be to push away handle 171 during use, but push-and-pull this removable saw blade 16 remake and locatees the body of rod 173 and get final product to required spacing with what this moved seat 17, this removable saw blade 16 promptly is positioned at adjusted position, no longer mobile, with board to be started, rotation rotating shaft 11 is done the action of cutting timber;
Yet, the locating ring 161 and rotating shaft 11 external diameters of removable saw blade 16 need close fit, rotating shaft 11 top offset locating rings 161 again spin, so during processing and forming, its precision does not have mistake, therefore the locating ring 161 of this removable saw blade 16 is used copper products always, make removable saw blade 16 and move seat 17 slips on rotating shaft 11, again because of often adjusting and the locating ring 161 of roving removable saw blade 16, directly rub with rotating shaft 11, the wearing and tearing locating ring produces the gap, and cutting timber process has dust can infiltrate in the locating ring 161 of removable saw blade 16, causing card to end and slippage has some setbacks, is that industry perplexs;
Tradition moves seat 17 following disappearance:
One, dust can infiltrate in the locating ring 161 of removable saw blade 16, causes card to end and slippage has some setbacks;
Two, the locating ring 161 of removable saw blade 16 and rotating shaft 11 external diameters are when processing and forming, and its precision does not have mistake, wastes time and energy during manufacturing;
Three, locating ring 161 contacts closely with rotating shaft 11, and running fix ring 161 is pure to be friction, and resistance is big, promotes effort, and under the situation of often wearing and tearing, 161 life-spans of locating ring are not long;
Four, the locating ring 161 of the removable saw blade 16 of copper (moving seat 17) increases the manufacturing industry cost;
Five, the locating ring 161 easy to wear and losses of the removable saw blade 16 of copper (moving seat 17), and cause the location undesired.
