Abstract
The utility model discloses a lifting mechanism with a lead screw pair, which comprises a lead screw, a ball nut, a support pole and a loading platform. The ball nut is matched with the thread of the lead screw, the two ends of the support pole are connected with the nut and the loading platform respectively, and the up-and-down movement of the loading platform is done through the rotation of the lead screw. The mechanism has the advantages of little space occupation, smooth operation, can be widely used in various mechanical equipment.
Description
Technical field the utility model relates to a kind of mechanical elevating mechanism, relates in particular to a kind of lifting mechanism that has lead screw pair.
In the background technology prior art, lifting mechanism has a lot of implementation methods, wherein in the majority with cam mechanism and rocker mechanism, their advantage is simple in structure but the bigger problem of mechanism's volume when having big stroke applications, when the application of mechanism runs into space constraint, tend to occur the not enough or not enough problem of mechanism's installing space of mechanism's stroke, it as the disclosed application number of Chinese patent communique 97123130.3 automatic Mah-jongg machine patent, what its mah-jong pieces wall lifting mechanism adopted is cam mechanism, it is bigger to take the inner space, when mechanism's overall dimensions is restricted, because of problems such as mechanism's lifting travel can not be used larger-size board.
The summary of the invention the purpose of this utility model provides a kind of little lifting mechanism that operates steadily, takes up room.
The utility model is achieved in that a kind of lifting mechanism that has lead screw pair, include leading screw 1, nut 2, pole 3, mounting table 5, nut 2 and leading screw 1 screw thread fit are on the nut 2 porose 6, the side of mounting table 5 is porose 7, and the two ends of pole 3 cooperate with hole 6 and hole 7 respectively.
There is projection 8 end of described mounting table 5, in the end of lifting mechanism baffle plate 9 is arranged, and the groove 10 that cooperates with projection 8 is arranged on the baffle plate 9.
Described leading screw 1 two ends have the opposite screw thread of rotation direction.
Described baffle plate 9 respectively has one at the two ends of this mechanism.
Have the bearing installation position 4 of supporting leading screw on the described baffle plate 9.
Described nut 2 is a ball nut, and it includes the interior cover 12 and the nut overcoat 13 of ball 11, band guide hole, and ball 11 is embedded in the guide hole of interior cover 12.
The cross-sectional plane of projection 8 is a kind of in trapezoidal or the rectangle.
After adopting said structure, the shared space of this lifting mechanism is less relatively and stroke and mechanism's volume-independent in the shared space of vertical direction particularly, and in the bigger application scenario of lifting travel, this mechanism and cam or rocker mechanism specific volume mutually greatly reduce.In addition, cooperate closely between ball nut and threads of lead screw make the mechanical operation resistance little, operate steadily, and low tolerance clearance also brings the accuracy of positioning height to be easy to cooperate the advantage of autonomous cruise speed system.The screw thread of the opposite rotation direction that the leading screw two ends have makes ball nut watch the step counter motion with the rotation of leading screw on threads of lead screw, offset pole component in the horizontal direction, the baffle plate of the band groove that is provided with in the mechanism end in addition also makes the dipping and heaving of mechanism more steadily reliably have the motion guide effect simultaneously concurrently as the operation slide rail of mounting table when the guide screw movement pair supported providing.
The utility model is described in further detail below in conjunction with accompanying drawing for description of drawings.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of nut in the utility model;
Fig. 3 is the structural representation of mounting table end in the utility model;
Fig. 4 is the structural representation of baffle plate in the utility model.
The specific embodiment as shown in Figure 1, the utility model includes leading screw 1, nut 2, " U " type pole 3, mounting table 5, and nut 2 and leading screw 1 screw thread fit have side opening 6 on the nut 2, side opening 7 is arranged on the mounting table 5, and the two ends of " U " type pole 3 cooperate with side opening 6 and side opening 7.
Leading screw 1 two ends have the opposite screw thread of rotation direction, and a cover nut 2 respectively is installed on the threaded portion at leading screw 1 two ends.
The both sides of mounting table 5 have cross-sectional plane be rectangle or trapezoidal projection as shown in Figure 3, groove 10 (see figure 4)s that the bearing mounting hole 14 that cooperates with leading screw 1 is arranged on the baffle plate 9, match with projection 8 shapes on the mounting table 5, projection 8 can be slided in groove 10.
When leading screw 1 rotation, do mutual open and close movement along leading screw and make mounting table 5 along groove 10 up-and-down movements thereby leading screw 1 drives two ball nuts 2.
