Abstract
The utility model relates to an electric polishing machine with larger bearing capability and long service life. The machine comprises a main spindle box, a main spindle and front bearings at the output end of the main spindle and has the following characteristics: two or more than two front bearings at the output end of the main spindle are arranged in series connection and the main spindle box is in close fit with the bearing. As the two or more front bearings are adopted, the bearing capability can be dispersed to the two or more bearings, thus improving the bearing capability, enhancing the stability of rotation and also extending the use function of a product after lengthening the main spindle. With improvement on the processing technique of main parts of the whole product, the machine can ensure that the main spindle box does not burn in a working state without the assistance of any cooling exhaust systems.
Description
Technical field
The utility model relates to a kind of electric polishing machine that can be used as straight grinder (mould electric grind) and the use of angle grinding machine.
Background technology
The main spindle box position of all straight grinder series products on the existing market, big city scalds one's hand, take incessantly, less stable when main shaft is stressed, bearing capacity a little less than, the main spindle box fore bearing damages easily, makes complete machine shorten service life.
Summary of the invention
The purpose of this utility model is to provide a kind of electric polishing machine that has than large bearing capacity, long service life.
The technical solution of the utility model is as follows: the utility model mainly comprises main spindle box, main shaft, is positioned at the fore bearing of main shaft output, it is characterized in that: the fore bearing that is positioned at the main shaft output is provided with main spindle box and bearing tight fit for two or more series connection.
The utility model is compared with prior art: owing to adopted two or more fore bearings, make bearing capacity can be dispersed on two or more bearings, the bearing capacity stability that can be improved, rotate improves thus, the function of use of the product that also extended behind the main shaft lengthening.The utility model also by to the improvement on the entire product processing technique of main parts, can guarantee the utility model product under the assistance of cooling, air discharging system, and main spindle box is not hot down in working order.
Description of drawings
Fig. 1 is a kind of structural representation of long output shaft straight grinder.
Fig. 2 is a kind of structural representation of angle grinding machine.
Fig. 3 is a kind of partial structurtes schematic diagram of short output shaft straight grinder.
Label declaration: 1 collet, 2 main shafts, 3 protecgulums, 4 dust rings, 5 fore bearings (being positioned at the fore bearing of main shaft output), 6 circlips for shaft, 7 main spindle boxes, 8 rear bearings, 9 circlip for holes, 10 armature spindles, 11 shaft couplings, 12 screws, 13 bearing caps, 14 middle cover, 15 tooth sectors.
The specific embodiment
Fig. 1 is the structural representation of straight grinder, it comprises 1 collet, 2 main shafts, 3 protecgulums, 4 dust rings, 5 fore bearings (promptly being positioned at the fore bearing of main shaft output), 6 circlips for shaft, 7 main spindle boxes, 8 rear bearings, 9 circlip for holes, 10 armature spindles, 11 shaft couplings, 12 screws, 13 bearing caps, 14 middle cover, described fore bearing adopts dual bearing structure, main spindle box (7) and front and back bearings tight fit.
Fig. 2 is the structural representation of angle grinding machine, it comprises that 2 main shafts, 5 are positioned at the fore bearing of main shaft output, 7 main spindle boxes, 13 bearing caps, 15 tooth sectors, the described fore bearing 5 that is positioned at the main shaft output adopts dual bearing structure, main spindle box (7) and fore bearing tight fit.
Fig. 3 is the structural representation of another kind of straight grinder, it mainly comprises 1 collet, 2 main shafts, 5 fore bearings (promptly being positioned at the fore bearing of main shaft output), 6 circlips for shaft, 7 main spindle boxes, 8 rear bearings, 9 circlip for holes, 11 shaft couplings, described fore bearing 5 adopts dual bearing structure, main spindle box (7) and front and back bearings tight fit.
The procedure of processing of each critical piece of the utility model straight grinder is as follows:
(1) the machining spindle case 7: adopt that the machining center lathe is disposable finishes the shape to the main spindle box two ends, the processing of position size.
(2) processing middle cover 14: in order to guarantee to be installed in the concentricity of stop portion size after size that fore bearing in the middle cover 14 and main spindle box match and the middle cover, must be before every batch of middle cover of processing, earlier its middle cover anchor clamps location is in first car one cutter on this unwheeling bed, the middle cover workpiece that will need again to process sandwiches clamping back processing in the anchor clamps, guarantee that thus the middle cover centrad height that processes is accurate, reduce eccentric phenomena to greatest extent.
(3) main shaft afterbody and the armature spindle head processing of shape symmetry that links to each other with shaft coupling: necessarily require when machining spindle and armature spindle, while all adopt clamp workpiece, withstand the centre bore of workpiece after, with milling machine workpiece is machined again.
(4) require shaft coupling is carried out dynamic balancing processing, when running up, do not produce vibration to guarantee shaft coupling.
(5) processing of other parts is adopted existing processing mode to finish to get final product.
(6) parts of above-mentioned processing being carried out conscientious assembly and adjustment finishes.
Processing for above-mentioned each parts can independently machine in no particular order, or machines simultaneously.
Because main spindle box, middle cover, armature spindle, main shaft and shaft coupling have all been guaranteed concentricity separately in process, symmetry and dynamically balanced specification requirement, therefore, the straight grinder of assembling out (belonging to a kind of of electric polishing machine) has the concentricity of height, thereby the stability of having rotated when having guaranteed straight grinder work, also solved simultaneously because problem of temperature rise and the vibration problem that each assembling parts decentraction is produced, and owing to adopted dual bearing structure, make the bearing capacity of fore bearing output can be dispersed on two bearings, thereby can improve the bearing capacity of output shaft, help extending and export the length of main shaft, expanded original function of use.
Between protecgulum 3 and fore bearing 5, be provided with dust ring 4, help making the dust that enters in the protecgulum 3 under the blast effect of rotation at a high speed, to be ejected again outside the main spindle box 7.Thereby avoid wearing and tearing and minimizing the caloric value because of rub produced of dust to fore bearing 5.
The utility model infrastructure product can use at straight grinder (mould electric grind machine), electric angle grinder etc.
