Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the description of one step is done to the utility model:
Embodiment one
As depicted in figs. 1 and 2, top regulating handle is by back centre 33, adjustment handle 31 and regulate threaded rod 32 to form, back centre 33 is made up of a cone and a cylinder, cone is identical with cylindrical diameter, cone is in the outside of tail block 1, and cylinder has one section of outside at tail block 1 also to have one section in the inside of tail block 1.The adjustment threaded rod 32 of top regulating handle is provided with screw thread, and also has corresponding screw thread in the adjustment hole 11 of dead head, regulates the screw thread on threaded rod 32 to be mutually engaged with the screw thread in adjustment hole 11.Regulate one end of threaded rod 32 to be connected with adjustment handle 31, the other end is connected with back centre 33.Rotate clockwise and regulate handle 31, threaded rod can be made to move forward; Rotate counterclockwise and regulate handle 31, threaded rod can be made to move backward.And back centre 33 all can be driven to move in the same direction with threaded rod is mobile forward or backward.
Fixed handle is made up of handle 21 and handlebar 22, and one end of handlebar 22 and handle 21 connect into an entirety, and the other end of handlebar 22 is provided with screw thread.The upper end of handlebar 22 is cylindric, and lower end is shape of threads.Rotating clockwise handle 21 can allow handlebar 22 move down, and as shown in Figure 2, after back centre 33 is encountered in handlebar 22 folding process, firmly screws handle 21 and the position of handlebar 22 pairs of back centres 33 can be allowed to be fixed.Rotating clockwise handle 21 can allow handlebar 22 move up, and now, handlebar 22 can separate gradually with back centre 33.Rotate again after handlebar 22 and back centre 33 separate and regulate handle 31 just can regulate the position of back centre 33 again.
As shown in Figure 5, add man-hour to neck axle, the back centre 33 in the utility model coordinates with front top 612, and bit leg 7 is withstood on centre.Front top 612 are all fixed on driver plate 61 with driving lever 611, and driver plate 61 is fixed on the headstock 6, but driver plate 61 can rotate.Driving lever 611 can be driven when driver plate 61 rotates thus drive bit leg 7 to rotate around front top 612 and back centre 33 together.In order to successfully process neck axle, need respectively to bore a centre bore in the side of neck axle and bit leg 7, front top 612 withstand in the centre bore of the side of bit leg 7, and back centre 33 withstands in the centre bore of neck axle.And make two centre bores and front top 612 and back centre 33 central axis all on the same line.
As shown in Fig. 2, Fig. 3 and Fig. 5, before processing, bit leg 7 is placed between front top 612 and back centre 33, and allows front top 612 and back centre 33 and corresponding central aperture.Rotate clockwise and regulate handle 31, threaded rod moves forward in adjustment hole 11, back centre 33 is also moved forward, reduces the spacing between front top 612 and back centre 33, until front top 612 withstand in corresponding centre bore all comparatively compactly to back centre 33.Then rotate clockwise handle 21, allow handlebar 22 move down in fixing hole 12, until handlebar 22 touches back centre 33 and fixed by back centre 33.At this moment just can machined axle journal 71.After processing, rotate counterclockwise handle 21 and allow handlebar 22 move up in fixing hole 12, until handlebar 22 leaves back centre 33, then rotate counterclockwise adjustment handle 31, allow threaded rod move backward in adjustment hole 11.Spacing between front top 612 and back centre 33 is increased gradually, until can be taken out by bit leg 7 easily.
As shown in Figure 4 and Figure 5, in order to allow back centre 33 and front top 612 on concentricity axis, just need back centre 33 being fixed on height and left and right directions.The structure that the present embodiment adopts is: on crane span structure base 51, open four bolts hole 52, crane span structure 5 is fixed on guide rail 4 by bolt passing through bolt hole 52; Also respectively have four bolts hole 52 above crane span structure 5 He below tail block 1, tail block 1 is fixed on crane span structure 5 through eight above-mentioned bolts hole 52 by bolt.
Obviously, under the prerequisite not departing from principle described in the utility model, the some improvement made or modification all should be considered as protection domain of the present utility model.
