Specific embodiment
A kind of novel clamp for turning turbocharger rotor axis of embodiment
A kind of novel clamp for turning turbocharger rotor axis, is configurable on horizontal NC lathe, this is horizontal
The horizontal NC lathe that hydraulic station drive cylinder pull rod unclamp the movement of clamping chuck specifically can be used in numerically controlled lathe.Such as figure
Shown in 1, including attachment base 5, terminal pad 1, sliding seat 2, spacer 6, top 7, clamp body 3 and end cap 4.It is described as shown in Figs. 1-2
Terminal pad 1 is that cylindrical structure is provided with several bolt mounting holes along the short transverse of cylindrical body, makes on the outer ring of terminal pad 1
Terminal pad 1 is bolted on the main shaft end face of numerically controlled lathe.In terminal pad 1 with the end-acted one end of main shaft have with
Attachment base 5 cooperates the first limiting groove, and one end of the attachment base 5, which is located in the first limiting groove, forms seam allowance positioning, connection
The other end of seat 5 is connected by the pull rod of screw thread and numerically controlled lathe.Top 7 are installed on the other end of terminal pad 1, this top 7
With integrally formed location and installation portion and top tip part, there is mounting hole positioned at the periphery of top tip part in the location and installation portion,
So that at the top center for being fixedly mounted on terminal pad 1 by location and installation portion.The center of the sliding seat 2 is set in top 7
Location and installation portion on, the sliding seat 2 be cylindrical structure, both ends be respectively provided with the second limiting groove and third limit it is recessed
The other end of slot, second limiting groove and terminal pad 1 acts on forming seam allowance positioning, that is, installs top 7 terminal pad 1
End face is located in the second limiting groove；Sliding seat 2 passes through terminal pad 1 by three spacers 6 and connect with attachment base 5, so that sliding
Seat 2 can carry out axial sliding in terminal pad 1.The clamp body 3 is frame type clamp body, is mounted on sliding seat 2, end cap
4 are mounted on frame type clamp body 3.One end of the frame type clamp body, which is located in the third limiting groove of sliding seat 2, to be formed
Seam allowance positioning, the other end are the design of open type structure, and end cap 4 is mounted on open end, form the two sides of frame type clamp body 3 and open
Hole.
The installation method of above-mentioned novel clamp is as shown in Figure 1:
Installation attachment base 5 is connected through a screw thread on the original pull rod of numerically controlled lathe first；
Then it is fixedly connected with disk 1 with bolt on main shaft end face, top 7 is installed on being fixedly connected with disk 1, top 7 installation
It is carried out after the completion to top 7 from vehicle using numerically controlled lathe, to guarantee top 7 in radial bounce precision；
Then sliding seat 2 and attachment base 5 are connected by spacer 6, guarantees that sliding seat 2 can carry out in fixed terminal pad 1
Axial sliding, then a frame type clamp body 3 is bolted and is mounted on sliding seat 2；
Finally end cap 4 is mounted on frame type clamp body 3, realizes the substrate hold-down function of clamp body 3.
Above-mentioned novel clamp working principle is:
It on the basis of numerical-control horizontal lathe original oild chuck carries out that the novel clamp is installed, when the novel clamp
After being installed, the turbocharger rotor axis 8 that operator processes needs passes through the two sides tapping of frame type clamp body 3,
It is put into clamp body 3, then the center hole of the stub end of 8 one end of turbocharger rotor axis is registered to the top of the novel clamp
On point 7；When operator wants to clamp workpiece, first presses the tailstock on machine tool system panel and hold out against button, hydraulic station starts work
Make, push barrel of tail stock to stretch out, head into the center hole of 8 other end of turbocharger rotor axis, forms Double Tops knot with top 7
Structure；Then operator presses the chuck on machine tool system panel and clamps button, and hydraulic station is started to work, driven by oil cylinder pull rod
Attachment base 5, sliding seat 2, clamp body 3 and end cap 4 prolong axial direction movement together, and end cap 4 is made to be pressed on turbocharger rotor
On the end face of axis and top 7 form interaction force；Last operation person presses processing program start button, lathe spindle rotation
When turbocharger rotor axis rely on frictional force synchronous rotary, complete turnery processing.
