Description

The grinding mechanism of grinder

The utility model relates to the design of the grinding mechanism of stone grinding facility, detailed it, be a kind ofly to carry out grinding operation, be able to the grinding mechanism that in same space row establishes more group of grinding head by the single motor two groups of grinding heads rotations that link.

The grinder for stone of commonly seeing comprises Rack Body, crossbeam, column, plummer, control the motor and the grinding mechanism of each parts running, grinding mechanism has some grinding units, each grinding unit system sees through rotation structure interlock one grinding head with a hydraulic motor and carries out attrition process, when its arrangement is equipped on the pedestal apical margin, because hydraulic motor has suitable length and width size, and need leave the heat radiation that plurality of gaps is beneficial to motor running again between adjacent hydraulic motor, for limited pedestal apical margin area, grinding head quantity to setting virtually, in other words, the progression arrangement of tempering stone is difficult for, if the surface roughness of processed stone material is excessive, stone material easily takes place to be difficult to reach the careful effect of smooth surface by a grinding operation, the stone of often each grinding head being installed that tempers changes the outfit and is the stone that tempers of thinner progression, stone material is imposed regrind could obtain the careful stone material of smooth surface, so working (machining) efficiency is low; Can once finish attrition process for asking, also can improve base size, make its more hydraulic motor and grinding head, but thus, will definitely significantly improve the load of rack components such as crossbeam, column, heighten in the related grinder overall operation institute power consumption source that makes, and the frame design difficulty increases and manufacturing cost improves.

The purpose of this utility model provides a kind of grinding mechanism of grinder, and its each grinding unit carries out grinding operation by single motor two groups of grinding heads rotation that links, and is able to that row establishes more group of grinding head in same space.

The technical solution of the utility model is: a kind of grinding mechanism of grinder, comprise a location support body, one typing unit and several grinding units, the typing unit uprightly is equipped on location support body one side, each grinding unit uprightly is equipped on location support body opposite side in regular turn, it is characterized in that: grinding unit is by a hydraulic motor, two grinding heads and two are passed device and are formed, the hydraulic motor interlocking is in location support body apical margin, the rotating shaft of hydraulic motor extends the main shaft that axially links in the support body of location, main shaft be coupling the interlock one suitable thickness master gear, the upright respectively driven shaft of establishing in main shaft both sides, each the driven shaft top pinion that is coupling links with the master gear engagement; The driven shaft pivot overlaps an axle sleeve, axial more outward suit one overcoat of axle sleeve, and the overcoat build-in is in the support body of location; Each driven shaft end grinding head that is coupling respectively.

Be further described below in conjunction with embodiment of the present utility model and accompanying drawing thereof.

Fig. 4 is a B-B cutaway view among Fig. 2.

See shown in Figure 1, the electromechanics that the grinder for stone of commonly seeing comprises a Rack Body 1, a plummer 2, each parts running of a control is 3 and one grinding mechanism 4, Rack Body 2 is joined with a column 102 respectively by a crossbeam 101 two ends and forms, a base 103 is located in column 102 bottoms, crossbeam 101 is able to according to column 102 upper and lower displacements, column 102 is able to according to base 103 front and back synchronization-slidings, plummer 2 is located between each column, with the fixing processed stone material of bearing, grinding mechanism 4 is located at crossbeam 101 and can be carried out the processing of stone operation along crossbeam 101 left and right displacement.The utility model is to substitute the improvement design that grinding mechanism 4 is wherein done.

See shown in Figure 2, a kind of grinding mechanism of grinder, comprise a location support body 10, typing unit 20 and several grinding units 30, typing unit 20 uprightly is equipped on location support body 10 1 sides, each grinding unit 30 uprightly is equipped on location support body 10 opposite sides in regular turn, and this part is identical with the grinding mechanism of commonly seeing.

See Fig. 3, shown in Figure 4, present embodiment is characterised in that: each grinding unit 30 is by a hydraulic motor 31, two grinding heads 32 and two are passed device 33 and are formed, hydraulic motor 31 interlockings are in location support body 10 apical margins, the rotating shaft 311 of hydraulic motor 31 extends in the support body 10 of location, and mat shaft coupling 34 axial interlock one

main shafts

35,35 pivots of main shaft have bearing 351, so that main shaft 35 pivots in the support body 10 of location, main shaft 35 bottoms be coupling the interlock one suitable thickness master gear 352, location support body 10 inner upright two driven shafts 36 of establishing, upright respectively main shaft 35 both sides of establishing of each driven shaft 36, each driven shaft 36 top be coupling a pinion 362 and master gear 352 engagement interlocks; Driven shaft 36 axial pivots overlap an axle sleeve 37, make driven shaft 36 and axle sleeve 37 synchronizing shafts to shift reciprocately, several bearings 361 of axle pivot between driven shaft 36 and the axle sleeve 37, according to driven shaft 36 must be pivoted in axle sleeve 37, axle sleeve 37 outer axial again suit one overcoats 38, overcoat 38 build-ins make driven shaft 36 obtain the location in the support body 10 of location; Axle sleeve 37 and overcoat 38 tops are offered one respectively in contiguous master gear 352 sides and are kept away wheel mouth 372,382, pinion 362 wheel rims appear axle sleeve 37, overcoat 38 and master gear 352 engagements by keeping away wheel mouthfuls 372,382, and avoid that axle sleeve 37, overcoat 38 interfere with master gear 352 wheel rims, skewer lattice phenomenon; Axle sleeve 37 bottoms pass location support body 10 root edges and radially extend out the joint chair 374 that forms an annular, and a sheathed dirt-proof boot 39 between joint chair 374 and overcoat 38 root edges infiltrates the running of internal influence parts to avoid dust or lapping rejects;

See shown in Figure 4ly, pass device 33 and is made up of a pneumatic cylinder 331 and a priming ring 332 that pneumatic cylinder 331 is upright to be located in the location support body 10 and contiguous overcoats 38, pneumatic compression devices such as pneumatic cylinder 331 mat appendixs, aerostatic press (not shown) drive and operate; Priming ring 332 is abutted against in axle sleeve 37 bottom end faces, priming ring 332 side direction protrude out an auricle 3323, push shaft 3312 outer ends of pneumatic cylinder 331 pass location support body 10, its end joins with auricle 3323, be able in view of the above by push shaft 3312 priming axle sleeves 37, driven shaft 36 axial displacements, again, driven shaft 36 is terminal to be extended and passes priming ring 332 grinding head 32 that is spirally connected, and drives the grinding head 32 rotations grinding operation that carries out.

When 35 rotations of hydraulic motor 31 running interlock main shafts, so can driven shaft 36 rotations of main shaft 35 both sides be located in priming with the pinion that is positioned at its both sides 362 engagements by master gear 352, and then drive grinding head 32 rotations, so that stone material is carried out attrition process.The utility model has the advantages that each grinding unit 30 grinds with two grinding heads 32 of single hydraulic motor 31 interlocks, when several hydraulic motors 31 are equipped on location support body 10 apical margins, with space, the obvious increase that the grinding head quantity that is linked can be commonly used, for tempering the arrangement of thick, the thin progression of stone, can set the stone that tempers of more multistage number variation, improve grinding efficiency thus.
