Abstract
The invention belongs to the technical field of machine tools or devices using grinding or polishing belts, and particularly relates to a grinding machine. The grinding machine comprises a machine frame, a power device, a clamp lifting device, a pressing plate and a grinding cylinder. The grinding cylinder is fixed to the machine frame and is a hollow cylinder with one end closed, and a grinding material is arranged in the grinding cylinder. The lifting device is fixed to the machine frame. The pressing plate is provided with a through hole. The power device is fixed to the lifting device, and the output end of the power device penetrates through the through hole to be fixedly connected with a clamp. The clamp is connected with the output end of the power device, so that power is transmitted to a workpiece under the action of the power device to drive the workpiece to rotate. An output shaft of the power device can penetrate through the through hole formed in the pressing plate, so that it is avoided that the pressing plate interferes with rotation of the power device. The pressing plate can effectively prevent the workpiece from spinning the grinding material in the grinding cylinder out in rotating. In addition, when the workpiece rotates, the pressing plate can be properly pressed so as to increase the friction force between the grinding material and the workpiece and increase the grinding speed.
Description
Technical field
The invention belongs to the lathe or device technique field that use grinding or sand belt, particularly relate to a kind of sander.
Background technology
Polishing, refers to mill or wipes surface of the work, making the smooth exquisiteness of workpiece.In the process of mechanical workpieces, usually need to polish to workpiece, especially some hot investment casting workpiece.Existing polishing gimmick is mainly polished by grinding machine or craft.Manual grinding is mainly used in small-sized, off-gauge workpiece, and its main drawback is: labor intensity is large, and work danger coefficient is high, and work under bad environment, dust is many, noise is large.Grinding machine is used for the workpiece of shape criteria, is fixed on grinding machine by workpiece by fixture, and carry out grinding process by emery wheel to workpiece, operating efficiency is very fast.But, inwall and outer surface all need the workpiece of polishing, the column of such as hollow or the Tapered Cup etc. of hollow, need first to polish with the outer surface of sander to workpiece, and then the inwall of workpiece is polished, cannot polish together with inwall to the outer surface of workpiece simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of can the simultaneously outer surface of buffing work-piece and the sander of inwall.
In order to achieve the above object, the invention provides a kind of sander, comprise frame, power set and fixture, wherein, also comprise lowering or hoisting gear, pressing plate and mill tube, mill tube is fixed in frame, and mill tube is the hollow cylinder that one end is closed, abrasive material is provided with in mill tube, described lowering or hoisting gear is fixed in frame, and described pressing plate is provided with through hole, and described power set are fixed on lowering or hoisting gear, the output of power set through through hole, and is fixedly connected with fixture.
Principle of the present invention is: workpiece to be polished is put into the mill tube that abrasive material is housed, the inwall of workpiece and outer surface are all covered by abrasive material, by fixture by Workpiece clamping, start power set, workpiece rotates along with jaw, the surface of workpiece and inwall all produce relative motion with abrasive material, thus realize the polishing to workpiece.
Beneficial effect of the present invention is: fixture is connected with the output of power set, under the effect of power set, power is passed to workpiece, drives workpiece to rotate.The through hole that pressing plate is provided with can pass for the output shaft of power set, avoids the rotation of pressing plate to power set to have interference.Pressing plate can effectively prevent workpiece from being gone out by the abrasive material fine jade in mill tube when rotating, and in addition, when workpiece rotates, can be suitable exert pressure to pressing plate, to increase the frictional force between abrasive material and workpiece, accelerates the speed of polishing.
Further, described fixture is magnetic force chuck or air spider or oild chuck.Because workpiece is in rotation process, can produce a large amount of frictional force with during abrasive contact, compared with traditional mechanical clamp, magnetic force chuck, air spider and oild chuck all can provide larger clamping force, and clamping effect is better.
Further, described power set are servomotor, and compared with common electric machine, servomotor can control the angle of rotating accurately, and can adapt to frequent starting.
Further, described abrasive material is diamond abrasive or alumina abrasive or chromium oxide.Diamond abrasive to differ greatly the polishing of alloy workpiece for there is soft or hard, and alumina abrasive is used for the polishing of iron and steel parts except Al and Alalloy, and chromium oxide is used for the polishing of Al and Alalloy workpiece.
Further, described fixture is provided with rubber cushion, and owing to need ensure the clamping of workpiece, then need to apply larger clamping force to workpiece, rubber cushion can well prevent workpiece from damaging because clamping force is excessive.
Accompanying drawing explanation
Fig. 1 is the structural representation of sander embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: servomotor 1, oild chuck 2, mill tube 3, pressing plate 4.
As shown in Figure 1, a kind of sander, comprises frame, servomotor 1 and oild chuck 2, pressing plate 4 and mill tube 3, mill tube 3 is fixed in frame, mill tube 3 for upper end open lower end seal hollow cylinder, be provided with diamond abrasive in mill tube 3, pressing plate 4 is provided with through hole, the diameter of through hole is greater than the diameter of the output shaft of servomotor 4, and the output shaft of servomotor 4 through through hole, and is fixedly connected with oild chuck 2, oild chuck 2 and absorption surface place are provided with rubber cushion, and servomotor 4 is arranged in frame.
During specific works, regulate lowering or hoisting gear, servomotor 1 is moved up.In mill tube 3, put into part diamond abrasive, the abrasive material put into is paved, and cover the bottom of mill tube 3 completely.Workpiece to be polished is connected to fixation in oild chuck 2, regulates lowering or hoisting gear, servomotor 1 is moved down, then continue to put into abrasive material in mill tube 3, guarantee that abrasive material fully contacts with inwall with the outer surface of workpiece.Start servomotor 1, first rotate with lower speed band part of starting building, then slowly raise speed.The inwall of workpiece and outer surface fully and abrasive contact, and produce relative motion, thus achieve polishing while the inwall of workpiece and outer surface.When needs improve polishing speed, pressure can be applied to pressing plate 4, to increase the frictional force of abrasive material and workpiece.In addition, the oild chuck 2 in the present embodiment can be changed to magnetic force chuck or air spider, also can ensure the stable of workpiece when workpiece rotates.Meanwhile, different abrasive materials can be selected according to different workpiece.Diamond abrasive to differ greatly the polishing of alloy workpiece for there is soft or hard, and alumina abrasive is used for the polishing of iron and steel parts except Al and Alalloy, and chromium oxide is used for the polishing of Al and Alalloy workpiece.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
