Abstract

The utility model discloses a multistation stone automatic circular arc grinder. The utility model is composed of a base, a portal frame fixed on the base, a crossbeam, grinding heads driven by a motor, a cylinder which facilitates the grinding heads to stretch up and down, and work tables which are arranged under the grinding heads and can swing back and forth around a shaft. The crossbeam is arranged on the portal frame and can rise and fall up and down along a pillar of the portal frame, more than two grinding heads are movably arranged on the crossbeam, and the work tables with the corresponding number to the number of the grinding heads are arranged below the grinding heads. Therefore, that a plurality of circular arc surfaces of the same specification or different specifications are simultaneously or separately polished and ground can be realized. When the structure is adopted, the utility model has symmetrical stress during the work time, high rigidity, and stable machining, the circular arc surface of a work piece polished and ground by the grinding head is wide, and the grinding quality and the grinding efficiency are respectively improved.

Description

The automatic circular arc grinding machine of multistation

The utility model relates to a kind of stone machining equipment, specifically is meant the automatic circular arc grinding machine of a kind of stone material multistation.

At present, homemade stone material arc surface rubbing down plant equipment all is single station, i.e. grinding machine workpiece of can only polishing, it mainly is made up of bistrique and the work stage around the tight mechanism of strap clamp of axle swing of being located on single column cantilever, be characterized in the effect of bistrique by manual screw mechanism or motor reducer and cylinder, bistrique is moved horizontally or with the cantilever vertical lift on cantilever, realize the rubbing down of bistrique to workpiece, simultaneously below bistrique, be provided with the work stage that swings back and forth around central shaft, so can carry out the arc rubbing down to the stone material workpiece.But this machine is subjected to the limitation of cantilever design, and the width of rubbing down arc surface is less, and working (machining) efficiency and precision are all lower.The applicant proposed a kind of circular arc line cutter (patent No.: 992349761) in 1999, it is the cylindrical slide rail that two parallel placements are set on the revoliving arm of the driving part of circular arc line cutter and slave unit, thereby make golden steel cable form a movement in a curve track by the swing on the internal gear pitch circle, and the high-speed motion by golden steel cable, any arc of radius plate in the prescribed stroke scope is carried out processing of stone, and this circular arc line cutter can only cut the circular arc taper seat shaped stone material of different size and can not process its rubbing down.

The purpose of this utility model provides a kind of arc-shaped surface energy automatic polishing and polishing to stone material, and the several workpiece of energy while rubbing down, improves the automatic circular arc grinding machine of multistation of polishing quality and efficient.

The purpose of this utility model is achieved in that it is by pedestal 1, be fixed in the support on the pedestal 1, by motor 6 bistrique 3 that drives and the cylinder 8 that bistrique is stretched up and down, place work stage 4 bistrique 3 belows, that can swing back and forth around axle to form, it is characterized in that: described support is a gantry frame 2 that is fixed on the pedestal 1, on gantry frame 2, be provided with the crossbeam 5 that to do oscilaltion along the pillar of gantry frame, can on crossbeam 5, make parallel mobile bistrique 3 and flexibly connect with crossbeam 5

Be intended to improve working (machining) efficiency, movable on the described crossbeam 5 plural bistrique be housed, the corresponding work stage that is provided with respective numbers in bistrique below,

In order to make bistrique oscilaltion freely on crossbeam, the utility model comprises that also can drive the transmission device that crossbeam moves up and down on gantry frame, described transmission device comprises motor 13, decelerator 11,12, and the screw mandrel 7 in two hollow columns 9,10 that are installed in gantry frame 2 respectively, and being connected in connecting axle 14 between decelerator and the screw mandrel, that be used for the rotation of motor is passed to the motion of screw mandrel, above-mentioned crossbeam 5 is threaded with screw mandrel 7.

Good effect of the present utility model is: the utility model is because with the independent cantilever that drives the bistrique lifting and move on single station grinding machine, change the gantry frame structure of forming by pedestal and support into, on this structure, be provided with the crossbeam of lifting vertically, so on crossbeam, can parallelly establish plural polishing and grinding head, and the corresponding work stage in bistrique below, realize several identical or different specification arc-shaped surface whiles or independent rubbing down.Adopt this structure, symmetry is stressed during work, just acts charitably, and processing is stable, and the cambered surface broad of bistrique rubbing down workpiece has improved polishing quality and efficient.Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model side-looking intention;

As shown in Figure 1, the utility model is example with the double, and it is fixed in the gantry frame 2 on the pedestal 1 by pedestal 1, and by bistrique 3 and the cylinder 8 that motor 6 drives, crossbeam 5, the transmission device that drives crossbeam oscilaltion on gantry frame, work stage 4 are formed.Transmission device is made up of decelerator 11,12, power transmission shaft sphere self-aligning bearing 14, screw mandrel 7, motor 13.

Decelerator 11 in the transmission device is installed in hollow column 9 upper ends, and is connected with the threaded one end of leading screw 7 with crossbeam 5 by connecting axle 14, and connecting axle 14 is made up of with 5 the identical band power transmission shaft of diameter sphere self-aligning bearings 6 shaft joints; Decelerator 12 and motor 13 are installed in the upper end of hollow column 10, and by the be threaded other end of crossbeam 5 of silk cup 7; Under the effect of motor 13, decelerator 11 will drive crossbeam 5 one ends by connecting axle 14 and screw mandrel 7, and decelerator 12 drives the other end of crossbeam 5 by leading screw, thereby can realize crossbeam 5 lifting vertically on gantry frame; Two motor 6 and cylinders 8 that drive bistrique 3 high speed rotating are installed on the crossbeam 5, also are equipped with simultaneously and can drive bistrique 3 parallel mobile motor 15 on crossbeam 5, cylinder 8 can stretch bistrique 3 up and down.In two work stage 4 below axle swings back and forth, places bistrique 3 of corresponding installation below two bistriques 3, can finish the fabrication and installation process of described grinding machine.

For improving working (machining) efficiency or as required, also movable on crossbeam 5 plural bistrique is housed, bistrique below correspondence is provided with the work stage of respective numbers.

When grinding machine is worked, can be according to stone material while or independent rubbing down to several identical or different specification arc-shaped surface.
