Detailed description of the invention
A kind of convenient expansion sleeve type fixed gear device taking out expansion set shown in composition graphs 1-8, comprise main body, described main body comprises the disk 1 be arranged on lathe spindle 13.Described disk 1 is provided with conical pipe 2 away from the one side of lathe spindle 13.Described conical pipe 2 diminishes gradually away from the part of disk 1, is arranged with the expansion set pipe 3 for Positioning Gear 4 outside conical pipe 2.The tube wall of described expansion set pipe 3 is provided with fluting under normal circumstances, in the process that is expansion set pipe 3 slides on conical pipe 2, owing to there being fluting, so expansion set pipe 3 can open in deformation, and can with reference to the locking mode of setscrew.Namely as Figure 1-4, expansion set pipe 3 is promoted left, and in the process be moved to the left, expansion set pipe 3 is strutted by conical pipe 2, the space of turgor between conical pipe 2 and gear 4 endoporus after expansion set pipe 3 deformation, and then is fixed from radial direction by gear 4.The mode promoting expansion set pipe 3 is a lot, and can be the cylinder arranged separately, cylinder power end connects block, and block promotes expansion set pipe 3, or other can play the mechanism of same effect.Certainly, also and not exclusive, described expansion set pipe 3 can also be that other have flexible structure to the structure of expansion set pipe 3, such as the rubber tube that tube wall is thicker, and the through hole of rubber tube is also tapered, when being extruded by block, and rubber tube distortion swelling gear 4.
What improvements of the present utility model were concentrated is embodied in, also comprise and take off grip assembly, the described grip assembly that takes off is included in the pin-and-hole 7 that disk 1 is arranged and the horizontal push-plate 8 be positioned at inside disk 1, the left side of the inner side of described disk 1 i.e. the disk 1 shown in Fig. 1-4.Described pin-and-hole 7 position is relative with expansion set pipe 3, and namely as shown in figs. 1-4, the position of pin-and-hole 7 is relative with expansion set pipe 3 left end face.Be equipped with slidably push rod pin 9 in pin-and-hole 7, described push rod pin 9 one end is relative with expansion set pipe 3, and the other end is relative with horizontal push-plate 8.Described horizontal push-plate 8 is connected with the angling cylinder power end 6 on lathe spindle 13.Horizontal push-plate 8 can promote push rod pin 9 vertically, thus allows push rod pin 9 promote expansion set pipe 3.
In the use of this device, first gear 4 and expansion set pipe 3 are in place and process by staff, when needs take off gear 4, because expansion set pipe 3, gear 4, conical pipe 2 are very tight, pole is not easy to take off, existing technology is taken off in the process of gear 4 at this and is wasted considerable manpower and materials, therefore often in the way changing workpiece, has the very long neutral gear phase.And the horizontal push-plate 8 of this device moves right under the drive of angling cylinder, now horizontal push-plate 8 touches push rod pin 9, and promotion expansion set pipe 3 moves right by push rod pin 9, and in the process of movement, expansion set pipe 3 shrinks lax.Now take off gear 4 and will become very light.Improve the efficiency changing workpiece greatly.
In order to make push rod pin 9 stressed effect better, described push rod pin 9 is provided with the head of large end face near one end of horizontal push-plate 8.This head also can play spacing effect, avoids push rod pin 9 to drop out on the right of pin-and-hole 7.As for spacing to push rod pin 9 of pin-and-hole 7 left side, common way is the length making the operating range of push rod pin 9 be less than push rod pin 9, namely push rod pin 9 can not drop out pin-and-hole 7 in the process be moved to the left, this is also easy to realize, and so push rod pin 9 moves back and forth and would not drop out pin-and-hole 7 in this space.In order to better realize the function of push rod pin 9, can also arrange helical spring 20 between the head of push rod pin 9 and disk 1, described helical spring 20 is set on push rod pin 9, and described helical spring 20 can play the effect of reset.Namely as shown in Figure 3,4, when horizontal push-plate 8 moves to right and promotes push rod pin 9, helical spring 20 is compressed; And as shown in Figure 1, 2, when horizontal push-plate 8 moves to left away from push rod pin 9, the elastic force that push rod pin 9 is subject to helical spring 20 is moved to the left reset.
In order to make the structure of described device compacter, the power that can be produced by angling cylinder acts directly on expansion set pipe 3, better way is, described disk 1 center is provided with through hole, described through hole is coaxial with conical pipe 2, described device also comprises pull bar 5, and described horizontal push-plate 8 is positioned in the middle part of pull bar 5.Described horizontal push-plate 8 is normally discoid, in processing, can in pull bar 5 process segment prefabricated one with it, and so the axial cross section of pull bar 5 is just in cross; Can certainly be that horizontal push-plate 8 welds or the mode such as to be threaded is fixed on pull bar 5.Pull bar 5 rear end is connected with angling cylinder power end 6, and front end is through through hole and conical pipe 2 and arrange blocking part, and described blocking part can press expansion set pipe 3 outer end under the drive of pull bar 5.
Arranging of described blocking part can be the back-up ring comprising the circle be connected with pull bar 5, and institute's back-up ring extends along conical pipe 2 radial direction, and extension and expansion set pipe 3 outer end form and keep out.Namely pull bar 5 right-hand member in the drawings connects a circular back-up ring, and described back-up ring extrudes expansion set pipe 3 under the drive of pull bar 5, and gear 4 is clamped.
Certainly better way is that described blocking part comprises the star block 11 being set in pull bar 5 outer end, and described conical pipe 2 outer end connects slotted-tube 10, is namely connected with the right-hand member of the conical pipe 2 shown in Fig. 1-4.Slotted-tube 10 sidewall is provided with many strip gabs extending longitudinally.Bifurcated on described star block 11 lays respectively in the opening on slotted-tube 10.Described pull bar 5 outer end is positioned at star block 11 arranged outside screw thread, and on this screw thread, adaptation has nut 21.That is star block 11 is arranged on pull bar 5 by nut, the bifurcated of star block 11 can move in opening, slotted-tube 10 is as the guiding parts of star block 11 movement, guide the moving direction of star block 11, bifurcated extruding expansion set pipe 3 on star block 11, expansion set pipe 3 swells and gear 4 is clamped.
In order to improve the stability of gear 4 axis, this device also comprises compressing member 12, and compressing member 12 is hollow cylinder and is set in slotted-tube 10 outer end vertically, and compressing member 12 is uncovered towards the bottom surface of disk 1.Described slotted-tube 10 outer end is positioned at compressing member 12 arranged outside screw thread, and on this screw thread, adaptation has nut 21, and namely compressing member 12 is fixed on slotted-tube 10 by nut 21.Described compressing member 12 diameter of bore is greater than the external diameter of expansion set pipe 3, is also greater than the maximum gauge of star block 11, and that is compressing member 12 is in the middle of the process of extruding gear 4, can not have influence on expansion set pipe 3, also can not affect by the bifurcated of star block 11.The diameter of described compressing member 12 is between gear 4 diameter and gear 4 diameter of bore, and namely the left end of compressing member 12 can be pressed in the entity part of gear 4 end face, compressing member 12 left end just can be made to be pressed on disk 1 by gear 4 by rotating nut 21.Certainly, described compressing member 12 can be not only above-mentioned shape, also can be cross, and the end of cross compressing member extends to the bending of disk 1 direction.Other similar settings are also feasible, as long as can compress gear 4, and do not affect the function of miscellaneous part.
