Abstract
The utility model relates to a lathe core shaft with an elastic clamping head, which belongs to the technical field of lathe fittings. The lathe core shaft comprises a core shaft body and an elastic clamping head at the end part of the core shaft body, wherein, the elastic clamping head comprises a plurality of clamping clacks distributed along the identical periphery, an opening seam extending from the head part of the elastic clamping head to the root part of the elastic clamping head is arranged between adjacent clamping clacks, an external thread is integrally formed by the external walls of the clamping clacks, a shaft hole is integrally formed by the inner walls of the clamping clacks, and an outer conical surface is formed by the end parts of the external walls of the clamping clacks; a locking nut is provided with an inner thread matched with the external thread of the external walls of the clamping clacks, and an inner conical surface matched with the outer conical surface of the end parts of the external walls of the clamping clacks is formed by the end parts of the inner walls of the locking nut. The lathe core shaft with the elastic clamping head has the advantages that the clamping is convenient, and the machining with high coaxial accuracy can be realized, thereby solving problems in the prior art that the requirement for processing precision is always difficult to meet as the workpiece with high requirement for coaxial accuracy is clamped and processed through adopting the three-jaw clamping head, and certain difficulties are caused to the machining.
Description
Technical field
The utility model relates to a kind of lathe mandrel with collet, belongs to the technical field of lathe accessory.
Technical background
When workpiece was machined, multiplex's part passed through the three-jaw chuck clamping to lathe.Yet adopt three-jaw chuck to carry out the requirement that clamping processing often is difficult to satisfy machining accuracy for the workpiece that axiality is had relatively high expectations, cause certain difficulty, can solve the Vehicle Processing requirement that adds high-axiality so demand a kind of anchor clamps urgently to Vehicle Processing.
Summary of the invention
The utility model purpose is to provide a kind of convenient mounting and clamping, can realize adding the lathe mandrel with collet of high-axiality Vehicle Processing, the workpiece of having relatively high expectations for axiality that has solved the prior art existence adopts three-jaw chuck to carry out the requirement that clamping processing often is difficult to satisfy machining accuracy, causes problems such as certain difficulty to Vehicle Processing.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises the collet of mandrel body and mandrel body end, described collet comprises some folder lobes along same circle distribution, have from the collet head between the adjacent folder lobe and extend to cracking of collet root, some folder lobe outer walls form external screw thread jointly, folder lobe inwall then forms axis hole jointly, and the outer wall end of folder lobe forms male cone (strobilus masculinus); Locking nut has the internal thread that cooperates with the external screw thread of folder lobe outer wall, and locking nut inwall end forms the inner conical surface that cooperates with the male cone (strobilus masculinus) of folder lobe outer wall end.Add man-hour, the workpiece end that needs clamping is inserted in the common axis hole that forms of folder lobe inwall, the rotation lock nut, cooperates with the external screw thread of folder lobe at the internal thread of locking nut that generation axially relatively moves between lower locking nut and the clamping plate, the male cone (strobilus masculinus) effect of the inner conical surface of locking nut and clamping plate is pressed to the center of circle with clamping plate gradually, thereby the common axis hole that forms of folder lobe is dwindled clamps workpiece, because some folder lobes are to draw in jointly under the effect of locking nut, therefore can guarantee the axiality of increasing between workpiece and the mandrel axis, thereby improved the axiality of Vehicle Processing, satisfied the Vehicle Processing requirement that adds high-axiality.
As preferably, form necking down between described collet and the mandrel body, described folder lobe root outer wall forms ring-shaped depression.Wherein, the gathering that the ring-shaped depression of locking between collet and the mandrel body and folder lobe root all helps pressing from both sides lobe is with handled easily.
As preferably, the described root that cracks forms the sub-circular enlarged portion, thus the gathering of being convenient to press from both sides lobe.
As preferably, described locking nut outer wall is provided with some spanners, thereby is convenient to the rotation of locking nut, is convenient to clamping.
Therefore, the utlity model has convenient mounting and clamping, can realize adding characteristics such as high-axiality Vehicle Processing.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the collet 2 that comprises mandrel body 1 and mandrel body 1 end, form necking down 3 between collet 2 and the mandrel body 1, collet 2 comprises three folder lobes 4 along same circle distribution, folder lobe 4 root outer walls form ring-shaped depression 5, have between the adjacent folder lobe 4 from what the collet head extended to the collet root and crack 6,6 roots that crack form sub-circular enlarged portion 13, folder lobe 4 outer walls form external screw thread 7 jointly, folder lobe inwall then forms axis hole 8 jointly, and the outer wall end of folder lobe forms male cone (strobilus masculinus) 9; Locking nut 10 has the internal thread 11 that cooperates with the external screw thread of folder lobe outer wall, and locking nut 10 inwall ends form the inner conical surface 12 that cooperates with the male cone (strobilus masculinus) of folder lobe outer wall end, and the locking nut outer wall is provided with two spanners 14.
Add man-hour, the workpiece end that needs clamping is inserted in the common axis hole that forms of folder lobe inwall, the rotation lock nut, cooperates with the external screw thread of folder lobe at the internal thread of locking nut that generation axially relatively moves between lower locking nut and the clamping plate, the male cone (strobilus masculinus) effect of the inner conical surface of locking nut and clamping plate is pressed to the center of circle with clamping plate gradually, thereby the common axis hole that forms of folder lobe is dwindled clamps workpiece, because some folder lobes are to draw in jointly under the effect of locking nut, therefore can guarantee the axiality of increasing between workpiece and the mandrel axis, thereby improved the axiality of Vehicle Processing, satisfied the Vehicle Processing requirement that adds high-axiality.
