Abstract
The invention relates to a clamping core rod for grinding and machining a gear. The clamping core rod for grinding and machining the gear is characterized by comprising a body; the body is formed by a first column body, a second column body, a third column body, a fourth column body and a fifth column body which are connected concentrically and sequentially; the diameter of the second column body is greater than that of the third column body; the diameter of the third column body is greater than that of the fifth column body; the diameter of the fifth column body is greater than that of the fourth column body; and the diameter of the fourth column body is great than or equal to that of the first column body; spiral holes are formed in both the central parts of two end surfaces on the body; and an external thread is machined on the outer side wall of the fifth column body. The gear which is formed by machining by adopting the core rod as an auxiliary clamping tool is high in machining accuracy and has long service life.
Description
Technical field
The present invention relates to a kind of roll flute processing and use aid, is the plug that is used for clamping workpiece in the gear grinding process specifically.
Background technology
At present, in field of machining, gear adds man-hour carrying out roll flute; Need annular workpiece to be processed is fixed on the trimming machine, and because the anchor clamps on the cutter are universal fixturing, it can only be clamped from both sides with workpiece; And the centre bore location that can't use workpiece, thereby make workpiece in cutting process, be easy to stressed and generation displacement radially; Thereby make that machining accuracy is difficult to guarantee, fraction defective raises.And the main countermeasure of available technology adopting is on workpiece to be processed, to reserve screw, when using the anchor clamps clamping workpiece of cutter, re-uses screw and carries out assist location.Though this method can be guaranteed machining accuracy, the effect that the screw on the workpiece just loses after machining, and, cause the strength of gear intensity that machines to descend because these screws have destroyed the overall structure of workpiece, shortened its service life.
Summary of the invention
The problem that the present invention will solve provides a kind of gear grinding processing and uses the clamping plug, the gear that adopts this plug to process as auxiliary clamping tool, and machining accuracy is high, and service life is longer.
For addressing the above problem, take following scheme:
A kind of gear grinding processing of the present invention is to comprise body with the characteristics of clamping plug; Said body is formed by connecting first cylinder, second cylinder, the 3rd cylinder, the 4th cylinder and the 5th cylinder successively with one heart, said second column diameter＞the 3rd column diameter＞the 5th column diameter＞the 4th column diameter >=first column diameter.All have screw at the both ends of the surface center position on the said body, be processed with external screw thread on the lateral wall of said the 5th cylinder.
Take such scheme, have the following advantages:
Because a kind of gear grinding processing of the present invention is formed by connecting first cylinder, second cylinder, the 3rd cylinder, the 4th cylinder and the 5th cylinder with the clamping plug successively with one heart; Said second column diameter＞the 3rd column diameter＞the 5th column diameter＞the 4th column diameter >=first column diameter; During use; Only need workpiece centre borehole jack to be processed on the 3rd cylinder; This moment, workpiece centre hole and the 3rd cylinder should closely cooperate fully, re-used briquetting and were placed on the 4th cylinder and complete workpiece pressing, screwed in and compress briquetting with nut from the 5th cylinder then; The screw that utilizes screw and plug body both ends of the surface at last is communicated with plug on the anchor clamps that workpiece to be processed is fixed on cutter, and carry out roll flute processing and process gear workpiece this moment again.Because a kind of gear grinding processing of the present invention is to utilize the centre bore of workpiece to position with the clamping plug; And the point of penetration extended line of bite processing passes through the axis of plug all the time; Therefore in the whole machining process process; Moving of any direction can not take place in workpiece, thereby guaranteed the machining accuracy of workpiece.In addition, adopt a kind of gear grinding processing of the present invention with the clamping plug workpiece to be processed to be positioned, need not on workpiece, to reserve screw, thereby can not destroy the overall structure of workpiece, do not influence it and receive force intensity, service life is longer.

Fig. 2 is the user mode sketch map of a kind of gear grinding processing of the present invention with the clamping plug.
The specific embodiment
As shown in Figure 1; A kind of gear grinding processing of the present invention comprises body with the clamping plug; Said body is formed by connecting said second cylinder, 3 diameters＞the 3rd cylinder 4 diameters＞the 5th cylinder 7 diameters＞the 4th cylinder 6 diameters >=first cylinder, 2 diameters successively with one heart first cylinder 2, second cylinder 3, the 3rd cylinder 4, the 4th cylinder 6 and the 5th cylinder 7.Said first cylinder 2 and second cylinder, 3 junctions, the 3rd cylinder 4 and the 4th cylinder 6 junctions all are circular-arc transition.On the 3rd cylinder 4 with on the end face of the 4th cylinder 6 links the boss 5 of cleat stanchion shape is arranged described in the present embodiment; The bottom surface of boss 5 links to each other with the 3rd cylinder 4; And the cross-sectional diameter of the two equates; The end face cross-sectional diameter of boss 5 is less than the cross-sectional diameter of boss 5 bottom surfaces, and this boss 5 and the 4th cylinder 6 junctions are circular-arc transition.All have screw 1 at the both ends of the surface center position on the said body, be processed with external screw thread 8 on the lateral wall of said the 5th cylinder 7.
As shown in Figure 2; During use; Only need workpiece to be processed 9 centre bores are enclosed within on the 3rd cylinder 4 of a kind of gear grinding processing of the present invention with the clamping plug; This moment, workpiece 9 centre bores and the 3rd cylinder 4 should closely cooperate fully, and cleat stanchion shape boss 5 designs on the 3rd cylinder 4 can be convenient to install processing work.Re-using briquetting 10 is placed on the 4th cylinder 6 and complete workpiece pressing 9; Screw in and compress briquetting 10 with nut 11 from the 5th cylinder 7 then; Utilize the screw 1 of screw and plug body both ends of the surface that plug is fixed on together with workpiece to be processed 9 on the anchor clamps of cutter at last, carry out roll flute processing and process gear workpiece 9 this moment again.
