Abstract
The utility model discloses a cover is pressed from both sides to frock of thin wall cover, including first cover and the second clamp cover of pressing from both sides, the first external diameter that presss from both sides cover and second clamp cover equals, first one end of pressing from both sides the cover is the three -jaw chuck link, the first other end that presss from both sides the cover is a threaded connection end, the end face centre of three -jaw chuck link has seted up first fixed orifices, the one end that the second pressed from both sides the cover is the 2nd threaded connection end that matees with threaded connection end, the end face centre that the second pressed from both sides the other end of cover has seted up the second fixed orifices, first fixed orifices and second fixed orifices are linked together and constitute the work piece fixed orifices, the internal diameter of first fixed orifices equals with the internal diameter of second fixed orifices. The utility model discloses a cover is pressed from both sides to frock of thin wall cover simple structure can make thin wall cover processing front and back can not warp, and part accuracy is controllable, few waste product.
Description
Technical field
The utility model relates to a kind of frock chuck, particularly relates to a kind of frock chuck of thin-wall sleeve.
Background technology
Existing thin-wall sleeve processing method, be that direct for part clamping is carried out grinding on the scroll chuck of internal grinder, clamping is easily out of shape, and element precision is difficult to control, and percent defective is high.
Utility model content
The purpose of this utility model is to provide a kind of frock chuck of thin-wall sleeve, and structure is simple, and thin-wall sleeve can be made to process front and back and all can not be out of shape, element precision is controlled, few waste product.
For achieving the above object, the utility model provides a kind of frock chuck of thin-wall sleeve, comprise the first chuck and the second chuck, the external diameter of described first chuck and the second chuck is equal, one end of described first chuck is scroll chuck link, the other end of described first chuck is the first threaded ends, and the end face center of described scroll chuck link offers the first fixing hole; One end of described second chuck is the second threaded ends mated with the first threaded ends, the end face center of the other end of described second chuck offers the second fixing hole, described first fixing hole is connected with the second fixing hole and forms workpiece fixing hole, and the internal diameter of described first fixing hole is equal with the internal diameter of the second fixing hole.
As further improvement of the utility model, the external diameter of described scroll chuck link is greater than the external diameter of the first threaded ends, the external diameter of described scroll chuck link is equal with the external diameter of the second chuck, described first threaded ends is provided with external screw thread, and described second threaded ends is provided with internal thread.
Further improve as of the present utility model, described second fixing hole extends outwardly at the second threaded ends place formation mounting groove, and described first threaded ends stretches in mounting groove.
Compared with prior art, the beneficial effect of the frock chuck of thin-wall sleeve of the present utility model is as follows:
(1), after the frock chuck adopting the first chuck and the second chuck to form, thin-wall sleeve can be made to process front and back and all can not be out of shape, element precision is controlled, few waste product.
(2) structure is simple, low cost of manufacture.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the frock chuck in the utility model.
Wherein, the 1, first chuck; 2, the second chuck; 11, scroll chuck link; 12, the first threaded ends; 13, the first fixing hole; 21, the second threaded ends; 22, the second fixing hole; 23, mounting groove.
Detailed description of the invention
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.
Please refer to Fig. 1, the frock chuck of described thin-wall sleeve comprises the first chuck 1 and the second chuck 2, and the external diameter of described first chuck 1 and the second chuck 2 is equal.One end of described first chuck 1 is scroll chuck link 11, and the other end of described first chuck 1 is the first threaded ends 12, and the end face center of described scroll chuck link 11 offers the first fixing hole 13.One end of described second chuck 2 is the second threaded ends 21 mated with the first threaded ends 12, the end face center of the other end of described second chuck 2 offers the second fixing hole 22, described first fixing hole 13 is connected with the second fixing hole 22 and forms workpiece fixing hole, and the internal diameter of described first fixing hole 13 is equal with the internal diameter of the second fixing hole 22.
Specifically, the external diameter of described scroll chuck link 11 is greater than the external diameter of the first threaded ends 12, the external diameter of described scroll chuck link 11 is equal with the external diameter of the second chuck 2, and described first threaded ends 12 is provided with external screw thread, and described second threaded ends 21 is provided with internal thread.Described second fixing hole 22 extends outwardly at the second threaded ends 21 place and forms mounting groove 23, and described first threaded ends 12 stretches in mounting groove 23.
When workpiece is installed, first, the first chuck 1 is installed on machine tool three-jaw chuck and corrects clamping, then the first fixing hole 13 of this first chuck 1 and excircle of workpiece match grinding.Secondly, utilize match grinding hole to locate, load onto workpiece.Again, the second threaded ends 21 of the second chuck 2 is screwed into the first threaded ends 12 of the first chuck 1, from workpiece end face clamping work pieces, just can processes thin-wall sleeve.After machining, turn on the second chuck 2, take out workpiece, at repetition said process, process next workpiece.Thus facilitate the clamping of workpiece, and effectively can prevent workpiece deformation, improve machining accuracy.To foreign round, the different workpiece of endoporus, the first corresponding chuck 1 and the second chuck 2 can be designed.
More than in conjunction with most preferred embodiment, the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contain various carry out according to essence of the present utility model amendment, equivalent combinations.
