The specific embodiment
Embodiment one
The lathe chuck that Fig. 4 provides for the utility model embodiment one claw structure schematic diagram, the utility model embodiment one provides a kind of lathe chuck claw, this claw comprises for the fixed part 8 that fixes with chuck and is used for the clamping part 9 of holding workpiece, fixed part 8 is mutually vertical L-shaped with clamping part 9, is provided with clamping face 10 on the clamping part 9; The span access location length to be held of the clamping length of clamping part 9 and workpiece to be held is complementary.The size that suitably designs clamping part 9 according to true form and the size of workpiece to be held, thus the clamping size of workpiece to be processed adapted to.
Identical with the claw mounting means of prior art, three or four above-mentioned claws are set on each chuck, the lathe chuck that Fig. 5 provides for the utility model embodiment one is installed in view on the chuck with claw, the lathe chuck that Fig. 6 provides for the utility model embodiment one view of claw holding workpiece, please be simultaneously with reference to Fig. 4 to Fig. 6, the example that is processed as with secondary cylinder, before secondary cylinder is carried out turning, the fixed part 8 of claw is fixedly connected with chuck 5, and the second seal head 4 with secondary cylinder stretches between the clamping part 9 of each claw again.Tighten up claw to second cylindrical tube 3 of clamping part 9 with secondary cylinder and clamp, can start lathe tool 13 and process.Because fixed part 8 is mutually vertical L-shaped with clamping part 9, can suitably design the size of clamping part 9 according to true form and the size of secondary cylinder, thereby adapt to the clamping size of secondary cylinder to be processed, and clamping part 9 is clamped on the outer wall of the second cylindrical tube 3.Above-mentioned claw simple in structure is convenient to processing and manufacturing, solved the inadequate defective of existing claw clamping length.
As shown in Figure 4, preferably, be provided with rounded transition 11 between above-mentioned fixed part 8 and clamping part 9, the setting of rounded transition 11 not only can improve the manufacturability of claw processing and manufacturing, and can avoid stress to concentrate, and improves the service life of claw.
Please refer to Fig. 4, claw is with chuck 5 fixed installation the time, and above-mentioned rounded transition 11 can be fixed towards the center of chuck 5, and also the center of chuck 5 is fixed dorsad.As shown in Figure 5, be rounded transition 11 mode of stationary jaw inwardly.When rounded transition 11 inwardly during stationary jaw, clamping face 10 is arranged on the one side near rounded transition 11, with holding workpiece.Rounded transition 11 is the mode of stationary jaw inwardly, and its advantage is, can effectively increase effective clamping diameter of claw, for the larger workpiece to be processed of diameter, can adopt this claw.
The lathe chuck that the utility model embodiment one provides with claw by fixed part and the clamping part that mutually vertically is the L shape is set, utilize the clamping part clamping to treat the workpiece of turning, make effective retaining part of the length adaptation workpiece to be processed of clamping part, solved defective of the prior art, simultaneously the lathe chuck that provides of the utility model embodiment one is simple with claw structure, is convenient to processing and manufacturing.
