[0006] Further, the connecting part is arranged radially along the end slot.

[0007] Further, the connecting part is boss.

[0008] Further, the boss is rectangular.

[0009] Further, two bosses are arranged in the end slot.

[0010] The utility model of a kind of axle head with boss structure has the following advantages:

[0011] The utility model sets up connecting part in the end slot of flange stopper, the connecting part can be directly matched with the shift lever on dial, saves the use and installation time of chicken heart chuck, and effectively improves work efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 It is a shaft head structure schematic view with boss structure of the utility model.

[0013] Figure 2 It is a right view of the utility model.

[0014] Mark explanation in the drawing:

[0015] 1, first bearing section;2, second bearing section;3, threaded section;4, flange plate;5, flange stop;6, end slot;7, first groove;8, boss;9, second groove;10, stepped shaft section. Specific implementation

[0016] In order to better understand the purpose, structure and function of the utility model, the utility model with boss structure of the shaft head is further described in detail below in conjunction with the drawings.

[0017] As Figure 1 And Figure 2 The utility model discloses a shaft head with boss structure, including shaft body and shaft end, and the shaft end is located at one side of the shaft body. And the end slot 6 is opened on the shaft end, and the connecting part that is matched with the shift lever of the dial is distributed around the axis in the end slot 6. The setting of the connecting part can make the power of the machine tool spindle be transmitted to the shaft head through the dial, realize the stable rotation of the shaft head directly with the dial, and facilitate the subsequent machining of the shaft head. And the setting of the connecting part can also save the use of the heart clamp, improve the work efficiency.

[0018] Specifically, the shaft body includes the stepped shaft section 10, the first bearing section 1, the second bearing section 2 and the threaded section 3 arranged in sequence, and the threaded section 3 is provided with the first groove 7. And the shaft end includes the flange plate 4 arranged at one end of the first bearing section 1 relative to the second bearing section 2 and the flange stop 5 arranged at one end of the flange plate 4. Wherein, the end slot 6 is opened on the flange stop 5. And the second groove 9 is opened in the center of the connecting part of the flange plate 4 and the stepped shaft section 10. Two centers on the machine tool can be respectively inserted into the first groove 7 and the second groove 9, and the shaft head is fixed through the two centers. At the same time, the shift lever on the dial is abutted with the connecting part, the machine tool is started, the machine tool is rotated through the shift lever on the dial, and the connecting part abutted with the shift lever will drive the shaft end and the shaft body to rotate, which is convenient for subsequent machining of the shaft head.

[0019] Specifically, the connecting part is radially arranged along the end slot 6, so that the shift lever of the dial is abutted with the connecting part. And the connecting part is the boss 8 outwardly protruding in the end slot 6. At the same time, the shape of the boss 8 is preferably rectangular. The setting of the rectangular boss 8 can improve the stability of the shift lever of the dial and the boss 8 connection. At the same time, it is also convenient for the corresponding connection of the shift lever and the boss 8.

[0020] As a further improvement, the boss 8 is provided with two in the end slot 6. The two bosses 8 can be made to have more selective dial lever, and can reduce the time to adjust the dial lever, further improve work efficiency. It should be noted that the number and shape of the boss 8 can be selected according to the actual use requirements, not too much limited here.

[0021] It can be understood that the utility model is described through some embodiments, and the person skilled in the art knows that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model.
