The present utility model relates to a stone edge grinding machine, which belongs to stone processing machinery.
TECHNICAL BACKGROUNDThe existing stone processing equipments have large volume and heavy weight and they are quite inconvenient to be moved, so they are not suitable to be used in some operational occasions. Moreover, in the existing stone edge grinding equipments, the electric motors with grinding wheel are generally arranged above the stones to be processed, and this operation mode is especially easy to block the operator's sight line so that the operator can not see the processing condition clearly and this may affect the processing quality. The applicant applied for a utility model patent entitled with “A stone edge grinding machine” on Aug. 30, 2002, and the patent was granted on Jul. 30, 2003 under the patent number ZL02276310.4. Due to that the special structure that the rocking arm and bolt head are positioned below the processing plates, the patented product has a compact structure, light weight and convenience in moving, as well as the advantages in being light and handy, convenient to be observed.
But it still has some disadvantages: 1. It can not perform the all-periphery operation for processing 360° of the circumferential perimeter of plate stock; 2. It can not use a template in the processing.
DISCLOSURE OF THE UTILITY MODELThe object of the utility model is to overcome the above defects in the structure of the existing stone edge grinding machines, and thus provides a stone edge grinding machine with modified structure.
To realize the above object, the utility model provides a stone edge grinding machine, including a bearing frame, a rocker arm system and a grinding wheel system, wherein: the said bearing frame comprises a base plate, a shaft fixed on the center of the base plate, a workbench connected fixedly to the top end of the shaft and a bracket mounted above the workbench in an order from bottom to top; the big end of rocker arm at one end of the said rocker arm system is sleeved rotatably on the shaft by a bearing, and the other end of the rocker arm system is joined with the grinding wheel system; the said grinding wheel system includes a grinding wheel and an electric motor with the grinding wheel mounted thereon. The electric motor is positioned below the grinding wheel.
As shown in
As another modification of the utility model in which a template is used, the grinding wheel system further comprises a central idler wheel which is positioned coaxially above the grinding wheel, that is to say, the grinding wheel is connected with the central idler wheel via a connector, and the connector is mounted to the shaft of the electric motor. Specifically, the central idler wheel is connected rotatably to the outer circumference of upper part of the connector through a bearing, and the grinding wheel is tightly fixed on the outer circumference of lower part of the connector through a screw nut; the inside of the said connector is formed with the screw thread engaged with the taper sleeve of the shaft of electric motor, and the lower end port of the said inside of connector is a conical surface matched with the taper sleeve of the shaft of electric motor. The connector is formed with a flange in the middle portion thereof to catch a spanner so that it may be mounted on the taper sleeve of the shaft of electric motor.
As shown in
As another modification of the utility model without a template, side idler wheels are provided along the outer flank of the grinding wheel in a horizontal plane, and the side idler wheel may be one or two.
As shown in
In another modification of the utility model, the side idler wheel is connected rotatably with the top of a shaft which is fixed on a supporting arm and parallel to the shaft of the electric motor; and the supporting arm is fastened directly or indirectly on the base of the electric motor.
The advantages of the utility model include: The stone edge grinding machine provided by the utility model has a simple structure, convenience in operation and precision in processing. It can perform an all-periphery operation for processing 360° of the circumferential perimeter of plate stock and a template can be used in the processing.
In the stone edge grinding machine of the utility model as shown in
As shown in
The connector 12 is a cannular part with small top and big bottom, the flange between the upper cannular part and lower cannular part is positioned between the central idler wheel and the grinding wheel; the inside of the said lower cannular part is formed with the screw thread engaged with taper sleeve of the shaft of the electric motor, and the lower end port is a conical surface matched with taper sleeve of the shaft of the electric motor.
