Abstract
The utility model relates to a clamping mandril for gear-grinding machining of a gear. The clamping mandril is characterized by comprising a body, wherein the body consists of a first, second, third, fourth and fifth cylinders which are concentrically connected in sequence, wherein the diameter of the second cylinder is greater than that of the third cylinder, the diameter of the third cylinder is greater than that of the fifth cylinder, the diameter of the fifth cylinder is greater than that of the fourth cylinder, and the diameter of the four cylinder is greater than or equal to that of the first cylinder. Screw holes are arranged at the center of the two end surfaces on the body, and external threads are machined on the outer side wall of the fifth cylinder. The gear machined by adopting the mandril as an assistant clamping tool has high machining precision and longer service life.
Description
Technical field
The utility model relates to a kind of roll flute processing and uses 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, needs annular workpiece to be processed is fixed on the trimming machine, and owing to the anchor clamps on the cutter are universal fixturing, it can only be clamped workpiece from both sides, and the centre bore location that can't use workpiece, thereby so that workpiece in cutting process, is easy to stressed and generation displacement radially, thereby so that machining accuracy is difficult to guarantee that fraction defective raises.And the main countermeasure of available technology adopting is to reserve screw at workpiece to be processed, when using the anchor clamps holding workpiece of cutter, re-uses screw and carries out auxiliary positioning.Although this method can be guaranteed machining accuracy, the effect that the screw on the workpiece just loses after machining, and because these screws have destroyed the overall structure of workpiece, cause the strength of gear intensity that machines to descend, shortened its service life.
The utility model content
Problem to be solved in the utility model 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 utility model is to comprise body with the characteristics of clamping plug, described body is formed by connecting successively with one heart by the first cylinder, the second cylinder, the 3rd cylinder, the 4th cylinder and the 5th cylinder, described the second column diameter＞the 3rd column diameter＞the 5th column diameter＞the 4th column diameter 〉=the first column diameter.All have screw at the both ends of the surface center position on the described body, be processed with external screw thread on the lateral wall of described the 5th cylinder.
Take such scheme, have the following advantages:
Because a kind of gear grinding processing of the present utility model uses the clamping plug by the first cylinder, the second cylinder, the 3rd cylinder, the 4th cylinder and the 5th cylinder are formed by connecting successively with one heart, described the second column diameter＞the 3rd column diameter＞the 5th column diameter＞the 4th column diameter 〉=the first column diameter, during use, only need workpiece center hole to be processed is enclosed within on the 3rd cylinder, this moment, workpiece center hole and the 3rd cylinder should closely cooperate fully, re-using briquetting is placed on the 4th cylinder and complete workpiece pressing, then screw in and compress briquetting with nut from the 5th cylinder, the screw that utilizes at last screw and plug body both ends of the surface is communicated with plug on the anchor clamps that workpiece to be processed is fixed on cutter, and carry out roll flute processing and make gear workpiece this moment again.Because a kind of gear grinding processing of the present utility model 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 whole process, the movement of any direction can not occur in workpiece, thereby has guaranteed the machining accuracy of workpiece.In addition, adopt a kind of gear grinding processing of the present utility model with the clamping plug workpiece to be processed to be positioned, need not to reserve screw at workpiece, thereby can not destroy the overall structure of workpiece, do not affect it and be subjected to force intensity, service life is longer.
Description of drawings
Fig. 1 is the structural representation that the clamping plug is used in a kind of gear grinding processing of the present utility model;
Fig. 2 is the use view that the clamping plug is used in a kind of gear grinding processing of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of gear grinding processing of the present utility model comprises body with the clamping plug, described body is formed by connecting successively with one heart by the first cylinder 2, the second cylinder 3, the 3rd cylinder 4, the 4th cylinder 6 and the 5th cylinder 7, described the second cylinder 3 diameters＞the 3rd cylinder 4 diameters＞the 5th cylinder 7 diameters＞the 4th cylinder 6 diameters 〉=the first cylinder 2 diameters.Described the first cylinder 2 and the 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 described body, be processed with external screw thread 8 on the lateral wall of described 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 utility model 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, then screw in and compress briquetting 10 with nut 11 from the 5th cylinder 7, utilize at last 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, carry out roll flute processing and make gear workpiece 9 this moment again.
