Abstract
The utility model provides a tensioning belt replacement device which comprises a motor installed on a base, wherein the rotary shaft of the motor penetrates through the base and is connected with a sponge wheel; a positioning block which can be fixed by a fixing shaft and can rotate is arranged below the same side of the motor; the positioning block is provided with a branch shaft which extends out of the outer edge part of the base, is provided with a rotary wheel at the same horizontal level with the sponge wheel and is sleeved on the sponge wheel and the rotary wheel by virtue of an abrasive belt; the other end, which is opposite to the branch pipe, of the positioning block is provided with a positioning bar; and a resetting spring is sleeved between the positioning bar and a strut body positioned on the base.
Description
Technical field
The utility model relates to the machinery equipment field of sand milling sheet material, relates in particular to the tensioning tape swapping device that a kind of staff can easily be changed abrasive band.
Background technology
The processing of sheet material be unable to do without the polishing in abrasive band, it is fine and smooth plane materiel from coarse surface conversion that abrasive band can make sheet material, the right-angle position at plate angle is become to fillet technique, current sand milling sheet material machine is mainly that abrasive band is installed on the sponge wheel, the soft feature of taking turns by sponge, the contact that the sponge wheel can be intact to corner or the surface of sheet material can be followed in the abrasive band that makes to be enclosed within on the sponge wheel, finally realizes the uniform grinding effect of sheet material.
Yet, what the polishing in abrasive band was difficult to avoid is the loss problem, current sander on the market is more only to be considered abrasive band is fixed, sheet material is carried out to sanding, can make the best use of everything in every one-inch position of but having ignored abrasive band, as when abrasive band need to be changed, traditional method is mainly that staff is pulled down the sponge wheel in the lump together with abrasive band, again new abrasive band is enclosed within on the sponge wheel, be installed to again machine shaft, it is both loaded down with trivial details that this changes operation, also easily make component wear, the workman blames the trouble of changing abrasive band often for, hindered the efficiency of polishing sheet material, moreover the sponge wheel is not established adjusting device with the spacing in abrasive band, therefore, traditional way is the size of regulation sponge wheel and runner, reenact out the abrasive band of corresponding size, excessive person easily gets loose, too small person can not install, this is for sander, unactual.
Summary of the invention
The utility model provides a kind of tensioning tape swapping device, and its main purpose is to allow the people easily change abrasive band, and does not need to employ instrument dismounting sponge wheel, has fast, realizes changing easily the purpose in abrasive band.
The utility model comprises the motor be arranged on pedestal, the rotating shaft of motor is connected with the sponge wheel through pedestal, with the same side-lower of described motor, be provided with by the fixing positioning piece of rotation of fixed axis, described positioning piece is provided with the fulcrum that protrudes out position, pedestal outer, the runner of taking turns into same level with sponge has been installed on described fulcrum, and has been set in by abrasive band on the position of sponge wheel and runner.
Wherein, the other end of the relatively described fulcrum of described positioning piece is provided with backstay, between described backstay and the strut members on described pedestal, is arranged with back-moving spring.
Described pedestal is provided with the gag lever post swung for limiting the positioning piece left.
Described pedestal is right angle plate body shape, and it has the rotating shaft and the fulcrum that supply described motor and passes the dull and stereotyped position of locating.
Described runner is sleeved on fulcrum rotationally in the sleeve mode.
Described motor and positioning piece are positioned at the same side of pedestal, and described sponge wheel and runner are positioned at the opposite side of pedestal.
The beneficial effects of the utility model are: the rotating shaft of motor is connected with the sponge wheel through pedestal, the same side-lower of described motor is provided with by the fixing positioning piece of rotation of fixed axis, the positioning piece is provided with the fulcrum that protrudes out position, pedestal outer, the runner of taking turns into same level with sponge has been installed on described fulcrum, and by abrasive band, be set on the position of sponge wheel and runner, the other end of the relative fulcrum of positioning piece is provided with backstay, between backstay and the strut members on described pedestal, is arranged with back-moving spring.
The accompanying drawing explanation
Fig. 1 is stereogram of the present utility model.
Fig. 2 is the plan view after motor that Fig. 1 removes.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described, as shown in Figure 1, the utility model comprises the motor 2 be arranged on pedestal 1, the rotating shaft of motor 2 is connected with sponge wheel 3 through pedestal 1, the same side-lower of described motor 2 is provided with by the fixing positioning piece 4 of rotation of fixed axis 41, described positioning piece 4 is provided with the fulcrum 42 that protrudes out pedestal 1 position, outer, runner 5 with 3 one-tenth same levels of sponge wheel has been installed on described fulcrum 42, and by abrasive band 6, be set on the position of sponge wheel 3 and runner 5, therefore, described motor 2 and positioning piece 4 are positioned at the same side of pedestal 1, described sponge wheel 3 and runner 5 are positioned at the opposite side of pedestal 1.
Further, for convenience of each parts, install, described pedestal 1 is right angle plate body shape, it has the rotating shaft and the fulcrum 41 that supply described motor 2 and passes the dull and stereotyped position of locating, the other end of the relatively described fulcrum 42 of described positioning piece 4 is provided with backstay 43, be arranged with back-moving spring 7 between described backstay 43 and the strut members 11 on described pedestal 1, and described pedestal 1 is provided with for limiting the gag lever post 12 that swings of positioning piece 4 left, 5 of described runners are sleeved on fulcrum 42 rotationally in the sleeve mode.
Therefore, described positioning piece 4 is centered by fixed axis 41, 42 of fulcrums are positioned at the oblique below, a left side of fixed axis 41, backstay 43 is positioned at the oblique lower position in the right side of fixed axis 41, when motor 2 drives 3 rotation of sponge wheel, sponge wheel 3 drives runner 5 by abrasive band 6 and together rotates, now, positioning piece 4 is subject to the restriction of strut members 11 and can only does to pedestal 1 outside slight swing, as shown in Figure 2, when motor 2 continues rotation, fulcrum 42 continues to adjust with fixed axis 41, now there is loosening sense in abrasive band 6, when fulcrum 42, when three fixing points of fixed axis 41 and sponge wheel 3 form a virtual line position, abrasive band 6 is collapsed to the tightest state, and when motor 2 stops operating, only need staff that positioning piece 4 is continued to outwards pendulum, so, abrasive band 6 again can be in loose state, now, people just can change.
Above-mentioned specific embodiment is only the utility model effect specific embodiment preferably, and all or tensioning tape swapping devices of being equal to identical with this structure, all in the application's protection domain.
