Abstract
This patent belongs to lathe or the technical field who uses grinding or polishing belt, especially relates to a sander, includes frame, power device and anchor clamps elevating gear, clamp plate and a mill section of thick bamboo, grinds a section of thick bamboo and fixes in the frame, grinds a section of thick bamboo and is one end confined cavity barrel, is equipped with the abrasive material in the mill section of thick bamboo, elevating gear fixes in the frame, be equipped with the through -hole on the clamp plate, power device fixes on elevating gear, and power device's output passes the through -hole to with anchor clamps fixed connection. Utilize anchor clamps and power device's output to be connected, the work piece is given in the transmission of will doing all can under power device's effect, and it is rotatory to drive the work piece. The through -hole that is equipped with on the clamp plate can supply power device's output shaft to pass, avoids the clamp plate to have the interference to power device's rotation. The clamp plate can effectually prevent that the work piece from will grind the abrasive material fine jade play in the section of thick bamboo when rotating, in addition, when the work piece rotates, can appropriately exert pressure to the clamp plate to increase the frictional force between abrasive material and the work piece, accelerate the speed of polishing.
Description
Technical field
The utility model belongs to the lathe or device technique field that use grinding or sand belt, particularly relates 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.
Utility model content
The purpose of this utility model be to provide a kind of can the outer surface of buffing work-piece and the sander of inwall simultaneously.
In order to achieve the above object, the utility model provides a kind of sander, comprises 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 utility model 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.
The beneficial effects of the utility model are: fixture is connected with the output of power set, under the effect of power set, power are passed to workpiece, drive 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 the utility model sander embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
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 embodiment of the present utility model, 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 the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.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.
