Abstract
The utility model relates to a screw nut pair and platform connecting and transmitting device in motor equipment, in particular to a screw flexible hinge connection device, which is characterized by including a hollow hexahedron including three groups of faces facing one other, wherein the centers of one group of faces are respectively provided with a circular hole. Six thread holes are evenly distributed on the periphery of the circular hole. The other two groups of faces are respectively provided with a first rectangular hole and a second rectangular hole. The four corners of the first rectangular hole are provided with semicircular grooves. The screw flexible hinge connection device has the advantage that 1) structure is simple, and an all-in-one frame structure is connected with a ball screw pair and the platform only through a connection plate; 2) the transmission effect is good. Not only is the axial transmission rigidity of the ball screw pair guaranteed but also the demand of radial flexible connection is satisfied; 3) manufacture and processing are convenient and the screw flexible hinge connection device is convenient to install and operate.
Description
Technical field
The utility model relates to the transmission device that is connected of screw pair and worktable in the electromechanical equipment, specifically is a kind of leading screw flexible hinge connection set.
Background technique
Screw pair comprises lead screw pair and ball screw pair, and it has location and transmission agency, is widely used in numerical control machine tool, surveying instrument, industrial robot and the various accurate mechanical equipment.Particularly along with the high speed development of machinery such as numerical control machine tool, machining center, as the leading screw of main drive actuating parts, its transmission accuracy requires more and more higher; The connection of leading screw and transmission usually directly influence the assembly precision and the Location accuracy of numerical control machine tool, and then have influence on every machining accuracy of numerical control machine tool; Especially the manufacturing of ball screw pair and alignment error can cause whole driving mechanism to produce the radial interference effect in the precision equipment, if ball screw pair and transmission part are to be rigidly connected just can not eliminate its radial force, can cause the guiding accuracy reduction of guide rail and the lost of life of transmission system, and can cause ball screw pair radially producing erection stress and causing periodic vibration, not only transmission and Location accuracy can be influenced, and the transmission efficiency and the working life of ball screw pair can be reduced.Therefore improve connecting into of ball screw pair and worktable in order to improve the important step of ball screw transmission accuracy.In order to improve the guiding accuracy of NC machine tool feed system, satisfy the high-precision requirement of numerical control machine tool processing, just need improve to satisfy and produce needs the connection of ball screw pair.If under the situation that guarantees the axial transmission stiffness of ball screw pair, changing ball screw pair into flexible hinge with being rigidly connected of worktable is connected, just can eliminate the radial force that causes by foozle and assembly error, avoid leading screw and guide rail to interfere, improve the transmission efficiency of ball screw and the guiding accuracy of transmission system, thereby realize the highi degree of accuracy and the feature of long life of ball screw pair.
Summary of the invention
The utility model provides a kind of leading screw flexible hinge connection set of integral frame-type, to eliminate owing to make and the problem of the radial interference that assembly error causes, with raising transmission efficiency and transmission accuracy.
To achieve these goals, the technical solution adopted in the utility model is: a kind of leading screw flexible hinge connection set, it is characterized in that: comprise hollow hexahedron, described hexahedron comprise be oppositely arranged three groups of faces, wherein the center of one group of face is respectively arranged with a circular hole, described circular is evenly equipped with six tapped holes, is respectively arranged with first rectangular opening and second rectangular opening on other two groups of faces, and four jiaos of first rectangular opening are provided with half slot.
Above-mentioned be provided with round-meshed one group of face for the square.
The utlity model has following advantage:
1) simple in structure; The integral frame structure only is connected with worktable with ball screw pair by connecting plate.
2) transmission is effective; The axial transmission stiffness of ball screw pair can be guaranteed, also the radial compliance connection request can be guaranteed.
3) manufacturing is easy to process, and is convenient to install and operation.
4) Applicable scope is extensive, can be widely used in being in transmission connection of various lead screw or ball screw.
