Abstract
The utility model discloses a quick self-centering chuck device of a square work piece. The main body of the device consists of a tapered shaft (1) and a tapered sleeve (2), wherein the left end of the tapered shaft (1) is a round shaft, the right end of the tapered shaft (1) is a four-unit elastic chuck (3) with a taper, a square opening is formed in the center of the four-unit elastic chuck (3), a thread is arranged at the middle of the tapered shaft (1), the tapered shaft (1) is connected with the tapered sleeve (2) through the thread, and the tapered hole of the tapered sleeve (2) is matched with the taper of the four-unit elastic chuck (3). When processing the square work piece, the round shaft at the left end of the tapered shaft (1) is tightly clamped on the three-jaw chuck on the turning machine, the square work piece is allowed to pass through the square opening in the center of the elastic chuck (3), the tapered sleeve (2) is rotated and driven to move forwardly and backwardly by the thread on the tapered shaft (1), so that the elastic chuck (3) generates the inward elastic deformation, resulting in quick self-centering chuck of the square work piece. The utility model has the advantages of no need of frequently replacing the chuck, low labor intensity and high production efficiency.
Description
Technical field
The utility model relates to the quick self-centering chucking device of a kind of square cross that uses in the machined into.
Background technology
Known machined into workpiece mainly is revolving body (as a round steel, steel pipe etc.), tightens with scroll chuck centering when being installed.When the processing square cross, must change chuck, adjust the four paws synchronization action, carry out machining with chuck centering chucking workpiece.Frequent chuck, the adjustment chuck changed, labour intensity is big, and production efficiency is low.
The utility model content
The purpose of this utility model is to provide a kind of square cross quick self-centering chucking device.
The technical solution of the utility model is: the quick self-centering chucking device of a kind of square cross, main body is divided into the axis of cone and tapered sleeve, axis of cone left end is a circular shaft, axis of cone right-hand member is broken elastic chuck off with the fingers and thumb for four of band tapering, four break the central. set squarely hole of elastic chuck off with the fingers and thumb, there is one section screw thread the centre of the axis of cone, and the axis of cone is by the tapered sleeve that has been threaded, and the taper hole on the tapered sleeve matches with the tapering of elastic chuck.
When processing square cross (as square steel, square steel tube), the circular shaft of axis of cone left end is clamped on the lathe scroll chuck, square cross is passed the square hole at elastic chuck center, the rotation tapered sleeve, tapered sleeve can move forward and backward by the transmission of screw thread on the axis of cone, the reach of tapered sleeve makes the quick self-centering chucking of the inside strain square shaped of elastic chuck workpiece, can realize the rapid-mounted processing of square cross, machine the back and move behind the tapered sleeve elastic chuck is outwards opened, take out the square cross after the processing fast.
The quick self-centering chucking device of the square cross that the utility model provides can realize fast that the self-centering of square cross is installed, and need not frequently change chuck, adjust four paws centering, greatly reduces labour intensity, enhances productivity.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the quick self-centering chucking device of the utility model square cross;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, the axis of cone 2, tapered sleeve 3, elastic chuck
As shown in drawings, the quick self-centering chucking device of the utility model square cross main body is divided into the axis of cone 1 and tapered sleeve 2, the axis of cone 1 left end is a circular shaft, the axis of cone 1 right-hand member is broken elastic chuck 3 off with the fingers and thumb for four of band tapering, a square opening is formed at four centers of breaking elastic chuck 3 off with the fingers and thumb, there is one section screw thread the centre of the axis of cone 1, and the axis of cone 1 is by the tapered sleeve 2 that has been threaded, and the taper hole on the tapered sleeve 2 matches with the tapering of elastic chuck 3.
When processing square cross (as square steel, square steel tube), the circular shaft of the axis of cone 1 left end is clamped on the lathe scroll chuck, square cross is passed the square hole at elastic chuck 3 centers, rotation tapered sleeve 2, tapered sleeve 2 can move forward and backward by the transmission of screw thread on the axis of cone 1, the reach of tapered sleeve 2 makes the quick self-centering chucking of elastic chuck 3 inside strain square shaped workpiece, can realize the rapid-mounted processing of square cross, machine the back and move behind the tapered sleeve 2 elastic chuck 3 is outwards opened, take out the square cross after the processing fast.
Claims (1)
1. quick self-centering chucking device of square cross, it is characterized in that: main body is divided into the axis of cone (1) and tapered sleeve (2), the axis of cone (1) left end is a circular shaft, the axis of cone (1) right-hand member is broken elastic chuck (3) off with the fingers and thumb for four of band tapering, four break the central. set squarely hole of elastic chuck (3) off with the fingers and thumb, there is one section screw thread the centre of the axis of cone (1), and the axis of cone (1) is by the tapered sleeve that has been threaded (2), and the taper hole on the tapered sleeve (2) matches with the tapering of elastic chuck (3).
