Description
Technical field
The utility model belongs to the anchor clamps field, specifically, relates in particular to a kind of Fixture for Gear-shaving for clamping, machining gears.
Background technology
As described in Figure 1, existing Fixture for Gear-shaving is nut compression type structure, specifically comprise mandrel 1, packing ring 2 and nut 3, wherein the center hole of center, mandrel 1 left side matches with gear shaving machine stationary center D1, and the center hole of center, mandrel 1 right side matches with gear shaving machine rolling center D2.The left part of described mandrel 1 is the 1a of positioning boss section, and the part on this positioning boss section 1a right side is positioning and guiding section, after positioning and guiding section cover is loaded onto tooth base C to be processed, is compressed by described packing ring 2 and nut 3.In Shaving Process, we find that there is following defective in existing anchor clamps:
1, because existing anchor clamps adopt the locate mode of shaft sleeve, and positioning accuracy is not high, eccentric situation appears easily;
When 2, installing and removing tooth base C, needs adopt spanner to tighten or unclamp described nut 3, waste time and energy, and clamping efficient is low.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of Fixture for Gear-shaving, and wish guarantees clamping precision, and is convenient to simultaneously install and remove the tooth base.
The technical solution of the utility model is as follows: a kind of Fixture for Gear-shaving, comprise mandrel (1), the center of this mandrel left side has the center hole that matches with gear shaving machine stationary center (D1), the left part of mandrel (1) is positioning boss section (1a), the position on this positioning boss section right side is positioning and guiding section, it is characterized in that: the flexible cover of coaxial package (5) successively from left to right in the positioning and guiding section of described mandrel (1), trim ring (6) and sleeve (7), the external diameter of these three parts is identical, the right-hand member of its middle sleeve (7) is closed, and has the center hole that matches with gear shaving machine rolling center (D2) in the center of this closing end;
Have axial groove (5a) on the circle wall of described resilient sleeve (5), end is the conical horn mouth about this resilient sleeve (5) endoporus, and the structure of these two conical horn mouths is identical; The right side of described trim ring (6) is ring surface, the conical horn mouth of its left side and described resilient sleeve (5) right-hand member adapts, and left section of described mandrel (1) positioning and guiding section is conical section, and the conical horn mouth of this conical section and described resilient sleeve (5) left end adapts.
In above structure, resilient sleeve (5), trim ring (6) are identical with the external diameter of sleeve (7), and the external diameter of these three parts is less about 20 than the aperture of tooth base (C) endoporus.
During clamping tooth base (C), first a tooth base (C) is sleeved on outside the resilient sleeve (5), secondly gear shaving machine stationary center (D2) is withstood the center hole on the sleeve (7), and control gear shaving machine stationary center (D2) moves to left, gear shaving machine stationary center this moment (D2) drives resilient sleeve (5) strain by sleeve (7) and trim ring (6), thereby the outer wall by resilient sleeve (5) positions the inner hole wall of tooth base (C), in order to carry out Shaving Process.After processing tooth base (C), at first gear shaving machine stationary center (D2) is laid down, because resilient sleeve (5), trim ring (6) are identical with the external diameter of sleeve (7), and the external diameter of these three kinds of parts is less about 20 than the aperture of tooth base (C) endoporus, so just can directly the gear that obtains after the processing be taken off.
Adopt above technical scheme, this Fixture for Gear-shaving positions by the inner hole wall of resilient sleeve (5) to tooth base (C), positioning accuracy is high, can prevent well off-centre, and the mounting or dismounting of tooth base (C) are convenient, overcome well the defective of existing structure, had good practicality, be suitable for extensively promoting the use.
For the ease of discharging the air in the described sleeve (7), guarantee successfully to carry out clamping, the special radially venthole (7a) that has in the right part of described sleeve (7).
As preferably, the length of described sleeve (7) is 50 to 70mm.In above design, the length of described sleeve (7) can not be long, can not be too short, oversize words can affect the rigidity of sleeve (7), thereby cause easily distortion of sleeve (7), and then affect clamping precision, and too short words just cause position length to fall short of, and so also can affect clamping precision.
As optimization, described mandrel (1) right side is 8 to 10mm to the inner surface of sleeve (7) right side distance.
As optimal design, the tapering of described resilient sleeve (5) conical horn mouth is 10 ° to 15 °.Equally, the tapering of described resilient sleeve (5) conical horn mouth can not be excessive, again can not be too small, and excessive words easily cause the deflection of resilient sleeve (5) excessive, thereby resilient sleeve (5) is swollen bad, self-locking easily occurs again in too small words.
Beneficial effect: this Fixture for Gear-shaving positions by the inner hole wall of resilient sleeve (5) to tooth base (C), and positioning accuracy is high, can prevent well off-centre, and the mounting or dismounting of tooth base (C) are convenient, overcome well the defective of existing structure, had good practicality, be suitable for extensively promoting the use.
