Description
Technical Field
The utility model relates to an anchor clamps are used in processing of quill shaft.
Background
The gear parts are widely applied in the mechanical industry, wherein the structural forms of the shaft parts are various, and if the shaft parts are externally provided with full splines and the middle of the shaft parts is hollow, the shaft parts are common.
In order to ensure the machining precision of parts, a center positioning cone with 60 degrees at two ends is usually directly positioned by using a center, and the problems of unqualified tooth surface roughness and ultra-poor tooth precision of parts are caused by overlarge deviation of tool shaking and tooth direction inclination in the machining process due to the interaction of tip pressure and conical surface friction because the force of the knurling and hobbing is large. When the part is serious, the part and the hob are expanded to generate deviation, the tooth part is twisted to be slightly spiral, the spline ring gauge cannot pass through, assembly cannot be achieved, and the part is scrapped.
Disclosure of Invention
The utility model aims at providing an effectual anchor clamps for quill shaft processing in order to improve the machining precision of centre gripping.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an anchor clamps are used in quill shaft processing, includes first axle end locating component and second axle end locating component, first axle end locating component includes the location axle that sets up along left right direction, location axle tip is the frustum structure and cooperates the cover that rises, second axle end locating component includes top, and top axis and the coaxial setting of location axle axis, top is put up and is furnished with actuating mechanism, the outer diameter of location axle tip reduces gradually to top side in order to form the frustum structure, the cover that rises is formed with the taper groove with frustum structure matched with, the cover that rises keeps away from top one end extend in order to be formed with outer boss to the circumference outside, outer boss external diameter is greater than the quill shaft internal diameter.
Carry out the utility model discloses during the use of anchor clamps, establish the quill shaft cover outside the cover rises to right the quill shaft, then start the top actuating mechanism of current drive so that top moves to the hollow shaft side, so that top promotion quill shaft moves to outer boss side, so that quill shaft axial terminal surface offsets with outer boss axial face, promote the cover that rises through top promotion quill shaft removal's mode and move on the frustum structure of location axle, thereby make the cover that rises rise to open in order to rise the quill shaft. After the machining is finished, the center is withdrawn, the hollow shaft does not apply force axially, the expansion sleeve can reset naturally, and the hollow shaft is separated from the expansion sleeve so that workers can take the machined hollow shaft away. Because the contact area between the expansion sleeve and the inner wall of the hollow shaft is large, the problem of insufficient positioning force can be thoroughly solved, so that the hollow shaft is prevented from rotating, and the processing precision is ensured.
Preferably, a positioning hole is formed in the end portion of the positioning shaft, a positioning groove is formed in the expansion sleeve, the inner section of the guide block penetrates through the positioning groove and then is fixed in the positioning hole, the distance between the front and rear groove walls of the positioning groove is larger than the distance between the front and rear side walls of the outer section of the guide block, and the positioning groove is of a strip-shaped groove structure arranged in the left-right direction. The arrangement is used for preventing the expansion sleeve from rotating on the positioning shaft so as to prevent the hollow shaft from rotating and ensure the machining precision. Wherein, the hollow shaft is prevented from rotating, the hollow shaft is not allowed to rotate, but the hollow shaft is prevented from rotating relative to the positioning shaft.
Preferably, an internal threaded hole is formed in the axial surface of the frustum structure of the positioning shaft and is matched with a bolt, a blocking piece is sleeved on the bolt, the outer diameter of the blocking piece is larger than the inner diameter of the expansion sleeve, and the blocking piece is limited between the head of the bolt and the expansion sleeve. The arrangement avoids the expansion sleeve from separating from the positioning shaft.
The utility model has the advantages of the centre gripping is effectual in order to improve the machining precision.
