Abstract
The utility model discloses a connecting device for a circular saw web and a machine tool spindle, which solves the problem of complicated operation and low precision of the existing clamping device. Six tapered holes and a central hole are opened on the circular saw web, and the circular saw web can be connected with a tapered hub by a sunk screw in advance; the tapered hub and the machine tool spindle are matched by adopting a 1:10 tapered hole and connected with each other by an inner hexagon screw, so that the circular saw web can be precisely and fast connected with a sawmill spindle; after installation, the outer side of the saw web keeps a flat surface. The connecting device has the advantages of simple structure, high revolving precision and excellent dynamic balance, can reduce the vibration and noise of a small sawmill and adapt to higher revolving speed and can also improve the cutting performance of the sawmill, therefore, the cutting quality of the sawmill can be improved.
Description
One, technical field
The utility model belongs to the coupling arrangement of saw blade and machine tool chief axis in the processing of timber or similar material.Relate in particular to circular saw blade for wood design and with the connecting of lathe.
Two, background technology
Circular sawing machine is simple in structure, and device fabrication and maintenance cost are low, is most widely used equipment in the wood working industry.Traditional circular sawing machine adopts two ring flanges (binding dish), nut and packing ring that saw blade is fixed on the saw main shaft.In order to guarantee all balanced participation cutting of cutters tooth all on the saw blade, require saw blade and saw main shaft to have higher axiality, the manufacturing and the installation accuracy of saw blade are had relatively high expectations.Simultaneously, because there are elements such as ring flange and nut in the saw outside, influence the cutwork of saw, the timber size that makes circular sawing machine to saw to cut open is much smaller than its saw blade diameter.
During practical application, because saw blade needs frequent reconditioning, to change conveniently in order to guarantee saw blade, saw blade installing hole and saw main shaft adopt matched in clearance, its fit tolerance is about 0.1mm, therefore the axis of rotation of saw blade often with the saw main shaft not point-blank, axiality is relatively poor, causes when work, the cutting output of each sawtooth is inconsistent, increase the vibration of saw blade, influenced the saw crudy, even damaged saw blade.Modern saw is in order to enhance productivity, and rotating speed increases substantially, but the saw blade of rotation has higher requirement to installation accuracy at a high speed, and traditional saw blade installation way has been difficult to meet the demands.
Three, summary of the invention
In order to overcome the existing existing above-mentioned deficiency of circular sawing machine installation way, technical problem to be solved in the utility model is, provides a kind of and can make saw blade and the device that the saw main shaft connects fast, effectively improves saw blade clamping speed and clamping precision.Have 6 bellmouths and a centre bore on the saw blade, can itself and tapered hub be connect by bellmouth with sunk screw in advance; Tapered hub and machine tool chief axis adopt 1: 10 taper hole to cooperate, and connect with a soket head cap screw.
Adopt above-mentioned device, have following advantage and technique effect:
The one, tapered hub and main shaft adopt 1: 10 taper hole to cooperate, and only connect with a soket head cap screw, can make saw blade and saw main shaft realize that fast precise connects, simple in structure, the rotating accuracy height has good dynamic balancing, reduce the vibration and the noise of saw, can adapt to high rotational speed.
The 2nd, can saw blade and tapered hub be connect by bellmouth with sunk screw in advance, make device simple to operate, it is convenient to change saw blade, and operating personnel are not had specific (special) requirements, applied widely.
The 3rd, after this device installation, the saw blade outside remains a plane, makes saw can process bigger workpiece, improves the cutting ability of saw, and the saw cutting quality is improved, and increases the scope of application of saw.
Four, description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model quick clamping device master apparent direction structural representation;
Fig. 2 is left apparent direction structural representation;
Fig. 3 utilizes this device processing log schematic diagram.
Among the figure: 1-saw blade, 2-saw blade hold-down screw, 3-tapered hub, 4-axle sleeve hold-down screw, 5-machine tool chief axis, 6-log, the horizontal saw of 7-, the vertical saw of 8-.
Five, the specific embodiment
The utility model is made up of saw blade 1, saw blade hold-down screw 2, tapered hub 3, axle sleeve hold-down screw 4 etc.
As depicted in figs. 1 and 2, have 6 bellmouths that saw blade hold-down screw 2 is installed and the centre bore that axle sleeve hold-down screw 4 is installed on the saw blade 1; The diameter of tapered hub 3 is generally 1/3 of saw blade 1 diameter, have above with saw blade 1 on corresponding 6 screwed holes in position.Saw blade 1 and tapered hub 3 connect by saw blade hold-down screw 2, and tapered hub 3 and machine tool chief axis 5 adopt 1: 10 taper hole to cooperate, and connect by axle sleeve hold-down screw 4.Saw blade hold-down screw 2 is a sunk screw, and axle sleeve hold-down screw 4 is a soket head cap screw.
When need replacing and reconditioning saw blade 1, only need unclamp axle sleeve hold-down screw 4,1 of tapered hub 3 and saw blade can conveniently unload from machine tool chief axis together, unclamp saw blade hold-down screw 2 again, and saw blade 1 is separated with tapered hub 3.Saw blade 1 after replacing or the reconditioning at first is linked together itself and tapered hub 3 with saw blade hold-down screw 2, with axle sleeve hold-down screw 4 they is connected on the machine tool chief axis 5 again.Because machine tool chief axis 5 and tapered hub 3 adopt taper hole to cooperate, and to the no any specification requirement of mounting or dismounting, have eliminated the fit clearance in traditional connecting mode simultaneously again, make the sawing precision of whole lathe be improved.
In said apparatus, the connection of saw blade 1 and tapered hub 3 adopts sunk screw to connect, thereby the outside that makes whole saw blade 1 is without any outstanding object, keep a flat state, thereby make saw can process bigger workpiece, adopt the such device of two covers, and make it become mutual plumbness, then can make it process large diameter log.
Fig. 3 because the saw blade outside remains a plane, thereby makes whole saw blade 1 all can contact log 6 surfaces, thereby realizes to process large diameter log than the circular sawing machine of small saw blade diameter for adopting the utility model processing major diameter log schematic diagram.
Claims (2)
1. a saw blade quick clamping device is made up of saw blade (1), saw blade hold-down screw (2), tapered hub (3), axle sleeve hold-down screw (4) etc., and it is characterized in that: the tapering of tapered hub is 1: 10.
2. a kind of saw blade quick clamping device according to claim 1 is characterized in that having 6 bellmouths and 1 centre bore that saw blade hold-down screw (2) usefulness is installed on the saw blade, and after the installation, the saw blade outside remains a plane.
