Description

The sanding machine pendulous device

One, technical field:

The utility model relates to a kind of sanding machine, relates in particular to a kind of sanding machine pendulous device.

Two, background technology:

Sanding machine is a kind of facility that are used for the grinding and polishing wood surface, and as shown in Figure 1, it is to be provided with a workbench 15 on a board 10, and is provided with in a side of workbench 15 and is used for the grinding group 20 of polishing material.This grinding group 20 mainly is to be respectively equipped with main,

passive roller

22,23 at the two ends of a carriage 21, wherein active roller 22 connects motor 24, be with 25 for driving the grinding of going up that is set around master,

passive roller

22,23, grind with the material on 25 pairs of workbenches 15 to utilize the grinding in rotating.

Yet such design, its grinding are with 25 to be that linearly formula is rotated, and that is to say that being positioned at the A point that grinds with on 25 only can move to A by horizontal linear, so its relative material also are the linearly grindings of formula.Because grind with having atomic little gap mostly between the fine sand on 25, it is more therefore to grind the material surface pore that comes out, and comparatively coarse.Moreover owing to grind with the 25 material sizes of grinding and the application of force all not necessarily, so the loss of its sand grains neither be very average, so can make material surface present irregular height fluctuating shape, has a strong impact on the quality of grinding.In order to improve above-mentioned problem, part user can improve its grinding effect with the method for left and right mobile material.Such practice, because user's application of force inequality, and gimmick and experience differ, it grinds quality to be difficult to control, so be not the real way of dealing with problems.

By above-mentioned explanation, we are appreciated that, because the grinding band of conventional polished machine is the design of linearly rotating, and the material that causes grinding to come out has many, the coarse and irregular problem of pore, influences the grinding quality of material.And, grind a kind of shuttle rotatablely moving of band generation if can make according to general grinding principle, and then can effectively overcome the problems referred to above, therefore if can develop the sanding machine that a kind of reciprocating type spin finishing action, be that industry and user expect.

Three, summary of the invention:

Five, the specific embodiment:

See also shown in Figure 2, the utility model sanding machine is to be provided with a workbench 55 on a board 50 tops, one side of workbench 55 is provided with a tool and grinds grinding group 60 with 65, and this grinding group 60 is to set up main,

passive roller

62,64 separately at the two ends of a carriage 61.Wherein active roller 62 is connected with a twin shaft motor 63, grinds and is with 65 to be surrounded on master, the

passive roller

62,64, after being with 65 to be driven when grinding, can the material on the workbench 55 be ground.And the end in addition of twin shaft motor 63 is connected with a pendulous device 70 that is hubbed on the carriage 61, so that the action that an end of 60 corresponding twin shaft motors 63 can produce left and right swing is organized in grinding.

Detailed structure of the present utility model, see also shown in Fig. 2,3, sanding machine is installed with a fixed bar 67 to workbench 55 extensions at an end of carriage 61 contiguous active rollers 62, be pivoted for pendulous device 70, and pendulous device 70 mainly is made up of the gag lever post 90 that a swing component 71, a drives structure 80 and are locked on the fixed bar 67.

Wherein an end of swing arm 71 corresponding carriages 61 utilizes hinged arm 72 to be hubbed on the fixed bar 67, make the carriage 61 of swing component 71 grinding groups relatively 60 produce the swing relation, the twin shaft motor 63 of grinding group 60 then is the stage casing that is locked in swing component 71, the end in addition of swing component 71 has vertically protruded out a lug 73, this lug 73 is locked and is provided with a drives structure 80, and this drives structure 80 is rotated synchronously by the end in addition of twin shaft motor 63.

Please cooperate and consult shown in Fig. 2,3,4; this drives structure 80 is to utilize bearing 83 to be pivoted with the scroll bar 82 of a connection twin shaft motor 63 in the framework 81 of a hollow; scroll bar 82 can be driven by twin shaft motor 63; and framework 81 is differing from the in addition side of twin shaft motor 63, and lock is provided with the side cover 84 that can protect scroll bar 82.Moreover, utilize bearing 86 to be pivoted with a turbine 85 that is meshed with scroll bar 82 in the framework 81 in addition, wherein bearings at both ends 86 is divided on the cover plate 87 of framework 81 both sides.The end that turbine 85 makes progress is installed with the axostylus axostyle 88 of a protrusion cover plate 87, and axostylus axostyle 88 free ends are provided with a biasing post 880, are arranged with a bearing 89 on the biasing post 880.

Again, the fixed bar 67 that grinding group 60 protrudes out out end in addition is provided with a gag lever post 90, this gag lever post 90 is to be screw shaped, and but spiral shell is located on the backstay 91 of a tool swivel nut 92, the lower end of backstay 91 is fixedly arranged on the fixed bar 67, the free end of this gag lever post 90 then is locked on holding on 89 of drives structure 80 axostylus axostyles 88, and group constitutes one and can allow grind with 65 and produce the sanding machine pendulous device of left and right slippage whereby.

The utility model operation principle and effect are as described below.Shown in Fig. 2,4, start the twin shaft motor 63 of sanding machine as the user after, it can drive the active roller 62 of grinding group 60, and the grinding band that drives grinding group 60 rotates, twin shaft motor 63 drives the scroll bar 82 of drives structure 80 synchronously simultaneously, rotate synchronously and make with scroll bar 82 intermeshing turbines 85, the rotation of turbine 85 makes the biasing post 880 on the axostylus axostyle 88 produce eccentric spinning movement.Because biasing post 880 is subject to the axle sleeve 93 of gag lever post 90 by bearing 89, gag lever post 90 is directly to be fixedly arranged on the fixed bar 67, therefore it have to oppositely drive drives structure 80 beats, because drives structure 80 is to be locked on the swing component 71, and swing component 71 is to be hubbed on the fixed bar 67.

So, can make swing component 71 and twin shaft motor 63 produce the action of swing synchronously, and active roller 62 1 ends that make grinding group 60 produce shuttle tiltedly action partially, and then allow the grinding that is set around active roller 62 also produce the phenomenon of left and right slippage with 65, make and grind the reciprocating type cutting force that forms a kind of line of cutting sth. askew with the abrasive grit on 65.Just as shown in Figure 4, grinding with a point on 65 in regular turn to b point and the slippage of c point, form a kind of grinding of tangent-type, the pore of abradant surface is significantly reduced, and the surface is careful, owing to the slippage of abrasive grains, therefore can obtain to grind more uniformly simultaneously, improve the flatness of lapped face, effectively improve whole grinding quality.

Because gag lever post 90 is to utilize backstay 91 to be locked on the fixed bar 67, therefore after 90s when user's rotary spacing bar, can adjust the distance of drives structure 80 axostylus axostyles 88 relative fixed bars 67, to adjust the pendulum angle of pendulous device 70.

In sum, the utility model is the splendid novel creation of an intention, and does not see identical or approximate product creation or public use in identical technical field, improves effect simultaneously, the utlity model has novelty, creativeness, practicality, so file an application in accordance with the law.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
