Abstract
The utility model relates to an elastic clamping sleeve for a main shaft, in particular to a tool clamping mechanism of a broaching tool component of the main shaft. The utility model discloses a cone frustum-like clamping sleeve main body (2) with an axial through hole, wherein at least two pairs of left-end kerfs (1) and right-end kerfs (3) are uniformly distributed on the clamping sleeve main body (2), and the left-end kerfs (1) are of axial kerfs from the left end to the near-right bottom of the clamping sleeve main body (1) on the outer wall of the clamping sleeve main body (2); and the right-end kerfs (3) are of the axial kerfs from the right end to the near-left bottom of the clamping sleeve main body (1) on the outer wall of the clamping sleeve main body (2). The elastic clamping sleeve has simple and flexible integral structure, is less prone to being stuck, small in circular runout and firm and can prevent foreign objects from entering into the main shaft and facilitate popularization and application.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind of cutter clamping device of main spindle broach assembly.
Background technology
In the prior art, the clamping device of main axle cutter is stuck easily when tool changing up and down, and broach force is unbalanced, firm, causes the main shaft work degree of accuracy low, and damages easily.
Summary of the invention
The utility model relates to a kind of main shaft and uses elastic jacket, and its terminal with compact integral structure, flexibly is difficult for stuckly, prevents that foreign object from getting into main shaft, and circle is beated little, firm, is convenient to promote and use.
The utility model technical solution is that the chuck main body (2) of tape spool to the frustum of through hole arranged; Chuck main body (2) is evenly distributed with at least two pairs of left end slots (1) and right-hand member slot (3), and said left end slot (1) is from the axial slot of the nearly right bottom of left end to chuck main body (1) on the outer wall of chuck main body (2); Said right-hand member slot (3) is from the axial slot of the nearly bottom left of right-hand member to chuck main body (1) on the outer wall of chuck main body (2).
The described chuck main body of above the utility model (2) is evenly distributed with at least three pairs of left end slots (1) and right-hand member slot (3).
The utility model axially pushes in the core, when its conical surface with after the conical surface of axle in the core contact, continue inwardly to move; Obtain enough radial pressures, because of two ends are evenly distributed with left and right end slot, this structure is shunk under the radial load effect; Cutter is clamped, thereby carry out cutting movement, elastic jacket is released in the other direction; Do not receive the effect of outer radial power, return back to original state, be held cutter and unclamp.
The advantage of the utility model is:
1, simple for structure flexible, the two ends slot can avoid an end to open the local deformation that slot causes, and has effectively increased the distribution of clamping force;
2, the conical surface basic circle is beated little, in 0.005mm;
3, chucking power is enough, and centering property is good.

The specific embodiment
Embodiment 1
According to Fig. 1, shown in Figure 2; The utility model has the chuck main body 2 of tape spool to the frustum of through hole; Chuck main body 2 is evenly distributed with two pairs of left end slots 1 and right-hand member slot 3, on the outer wall that said left end slot 1 is a chuck main body 2 from the axial slot of left end to chuck main body 1 nearly right bottom; On the outer wall that said right-hand member slot 3 is chuck main bodys 2 from the axial slot of right-hand member to chuck main body 1 nearly bottom left.
Embodiment 2
Identical with embodiment 1, be that described chuck main body 2 is evenly distributed with three pairs of left end slots 1 and right-hand member slot 3.
Claims (2)
1. a main shaft is used elastic jacket; It is characterized in that having the chuck main body (2) of tape spool to the frustum of through hole; Chuck main body (2) is evenly distributed with at least two pairs of left end slots (1) and right-hand member slot (3), and said left end slot (1) is from the axial slot of the nearly right bottom of left end to chuck main body (1) on the outer wall of chuck main body (2); Said right-hand member slot (3) is from the axial slot of the nearly bottom left of right-hand member to chuck main body (1) on the outer wall of chuck main body (2).
2. a kind of main shaft according to claim 1 is used elastic jacket, it is characterized in that described chuck main body (2) is evenly distributed with three pairs of left end slots (1) and right-hand member slot (3).
