Abstract
The invention discloses an indexing positioning mechanism which comprises a horizontal indexing plate. The indexing plate is fixed to a vertical main shaft. The indexing positioning mechanism is characterized in that the main shaft can reciprocate in the vertical direction; a horizontal groove disc is fixed to the main shaft; a driving plate capable of driving the groove disc to rotate is arranged in the side direction of the groove disc; the indexing positioning mechanism further comprises a supporting seat arranged below the indexing plate; a lower toothed ring is arranged on the upper portion of the supporting seat; the lower toothed ring is provided with an upper toothed ring in a meshed manner; and the upper toothed ring is fixed to the lower portion of the indexing plate.
Description
Technical field
The present invention relates to the calibration location technology of lathe index dial, be specifically related to a kind of dividing and positioning mechanism.
Background technology
Index dial is by piece-holder on chuck or two top, and make it rotate, the machine tool accessories of calibration and location, be used in automation equipment.The calibration of index dial and be located through dividing and positioning mechanism and realize, dividing and positioning mechanism is generally used in the calibration processing of workpiece, the especially circumferential Drilling operation of workpiece.The location of existing dividing and positioning mechanism is normally realized by click, and ratchet blocks the location that ratchet realizes index dial under the booster action of spring, and ratchet is positioned by ratchet after rotating under the drive of driving force and realizing rotating calibration again.Above-mentioned dividing and positioning mechanism is owing to have employed spring, and spring after long-term use, easy deformed damaged, and point location of determining detent mechanism can be caused unstable.
Summary of the invention
The invention is intended to the dividing and positioning mechanism providing a kind of Absorbable organic halogens to locate.
A kind of dividing and positioning mechanism in this programme, comprise the index dial of level, index dial is fixed on vertical main shaft, it is characterized in that, main shaft can move back and forth at vertical direction, main shaft is fixed with the slotted disk of level, the side direction of slotted disk is provided with the driver plate can stirred slotted disk and rotate, and also comprise the supporting seat be arranged on below index dial, the top of supporting seat is provided with lower ring gear, with lower ring gear engageable be provided with upper ring gear, described upper ring gear is fixed on the bottom of index dial.
Operation principle and the beneficial effect of the present invention program are as follows: when needing index dial to rotate calibration, main shaft moves upward, ring gear and lower ring gear are thrown off, then stirs slotted disk by driver plate, because slotted disk and main shaft are fixed, therefore main shaft can be driven to rotate an angle, main shaft drives index dial to rotate equal angular, and after calibration, main shaft declines, thus make ring gear and the engagement of lower ring gear, thus realize the stable location of index dial.The present invention adopts the cooperation of ring gear and lower ring gear to realize the location of index dial, upper ring gear and lower ring gear in use not fragile, therefore Long-Time Service, also possesses stable locating effect.
Further, the driving mechanism of drive shaft vertical direction motion comprises vertical rotating drum cam, the side direction of drum cam is provided with fork, can slide along annular groove in the annular groove that one end of fork extend into drum cam, the other end of fork is hinged, main shaft is provided with upper backing pin and lower backing pin along the axis direction of main shaft, described fork can respectively with upper backing pin and lower backing pin against.By the cooperation of drum cam and fork, the action of main shaft vertical direction can be realized.
Further, on the upper disk surface of driver plate, bias is provided with a roller, and described roller can offset with the groove of slotted disk and stir slotted disk.Stir slotted disk by the roller arranged, driver plate and the direct contact friction of slotted disk can be reduced large, the problem of easily wearing and tearing.
Further, the middle part of supporting seat has pilot hole, and described main shaft is through described pilot hole.Pilot hole is in main shaft vertical motion and effect when horizontally rotating, it being played to guiding.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: index dial 1, upper ring gear 2, lower ring gear 3, supporting seat 4, main shaft 5, slotted disk 6, roller 7, driver plate 8, drum cam 9, base 10, fork 11.
Embodiment is substantially as shown in Figure 1: the dividing and positioning mechanism of the present embodiment, supporting seat is frame shape, supporting seat comprises two vertical legs and the top cover with two legs one, top cover is positioned at medium position and has pilot hole, main shaft is through this pilot hole, the mode fixed indexing plate of interference fit is passed through in the upper end of main shaft, the fixing upper ring gear in bottom of index dial, the fixing lower ring gear in top of supporting seat, when index dial is located, upper ring gear and the engagement of lower ring gear, when index dial rotates calibration, upper ring gear and lower ring gear are separately.
In the present embodiment, the driving mechanism of drive shaft vertical direction motion comprises vertical rotating drum cam, the side direction of drum cam is provided with fork, can slide along annular groove in the annular groove that one end of fork extend into drum cam, the other end of fork is hinged, main shaft is provided with upper backing pin and lower backing pin along the axis direction of main shaft, described fork can respectively with upper backing pin and lower backing pin against.
In the present embodiment, the structure that drive shaft rotates comprises the slotted disk of the level be fixed on main shaft, and the side direction of slotted disk is provided with driver plate, and on the upper disk surface of driver plate, bias is provided with roller, and roller can offset with the groove of slotted disk and stir slotted disk.Driver plate is coaxial with drum cam, and the top and bottom of the axle of driver plate and drum cam are arranged on pedestal respectively by bearing.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
