Description
Technical Field
The utility model belongs to the technical field of the jacking equipment technique and specifically relates to a connection structure of screw thread lead screw is vice.
Background
Use many sets of screw lead screw driven jacking equipment simultaneously, under the influence of conditions such as topography condition, load, wind speed, the screw lead screw can receive the yawing force and take place the slope, receives the restriction of screw thread self transmission characteristics, if the screw thread secondary axis does not coincide, will very big increase transmission wearing and tearing not only reduce transmission efficiency, has cracked risk even.
SUMMERY OF THE UTILITY MODEL
In order to overcome not enough among the background art, the utility model discloses a vice connection structure of screw thread lead screw, the utility model discloses can improve transmission efficiency and reduce and damage the risk, make the vice orientation along with the yawing force slope of screw thread incline together, avoid appearing the cracked condition, simultaneously, the vice screw thread can not take place to interfere with other parts under the condition of slope, still can effectual transmission power.
In order to realize the utility model aims at, the utility model adopts the following technical scheme:
the utility model provides a connection structure of screw thread lead screw pair, includes the nut cover, lock nut and lower lock nut are installed respectively to the upper and lower both ends of nut cover, install axle bush and lower axle bush on last lock nut and the lower lock nut respectively, be equipped with the recess in the nut cover, install nut and contact connection between upper bearing bush and the lower axle bush, the both ends of nut are passed through connecting screw and are connected with the guide block, the guide block is located the recess on the nut cover, install the screw thread lead screw on the nut.
The two axial ends of the nut are both spherical.
And one end of the upper bearing bush, which is contacted with the nut, is positioned in a spherical shape.
And one end of the lower bearing bush, which is contacted with the nut, is positioned in a spherical shape.
The outer surface of the threaded lead screw is not contacted with the inner surfaces of the upper locking nut, the lower locking nut, the upper bearing bush and the lower bearing bush.
The number of the guide blocks is two, the two guide blocks are symmetrically distributed on the outer diameter of the nut, and a certain gap exists between the guide blocks and the groove in the nut sleeve.
Since the technical scheme is used, the utility model discloses following beneficial effect has:
a connection structure of screw thread lead screw pair, can improve transmission efficiency and reduce and damage the risk, make the screw thread pair along with the direction of yawing force slope is inclined together, avoid appearing cracked condition, simultaneously, the screw thread pair can not take place to interfere with other parts under the condition of slope, still can effectual transmission power.

Detailed Description
The invention will be explained in more detail by the following examples, the purpose of which is to protect all the technical improvements within the scope of the invention.
The connecting structure of the threaded lead screw pair includes a nut sleeve 4, an upper locking nut 2 and a lower locking nut 9 are respectively installed at the upper end and the lower end of the nut sleeve 4, an upper bearing bush 3 and a lower bearing bush 8 are respectively installed on the upper locking nut 2 and the lower locking nut 9, a groove is formed in the nut sleeve 4, a nut 7 is installed between the upper bearing bush 3 and the lower bearing bush 8 and is in contact connection, the position of the nut 7 is limited through the upper bearing bush 3 and the lower bearing bush 8, two ends of the nut 7 are connected with a guide block 5 through a connecting screw 6, the guide block 5 is located in the groove in the nut sleeve 4, and a threaded lead screw 1 is installed on the nut 7.
Both axial ends of the nut 7 are spherical.
One end of the upper bearing bush 3, which is contacted with the nut 7, is positioned in a spherical shape.
One end of the lower bearing bush 8, which is contacted with the nut 7, is positioned in a spherical shape.
The outer surface of the threaded lead screw 1 is not in contact with the inner surfaces of the upper locking nut 2, the lower locking nut 9, the upper bearing bush 3 and the lower bearing bush 8, so that the threaded lead screw 1 is ensured not to interfere with other parts during swinging.
The number of the guide blocks 5 is two, the two guide blocks 5 are symmetrically distributed on the outer diameter of the nut 7, and a certain gap exists between the guide blocks 5 and the groove on the nut sleeve 4, so that the swing amplitude of the nut 7 along the X axis and the Y axis is larger.
When the connecting structure of the threaded lead screw pair is used, a worker installs the nut sleeve 4 at a specified position and fixes the nut sleeve, and when the threaded lead screw 1 is inclined by lateral force during work, the threaded lead screw 1 can drive the nut 7 to incline simultaneously, so that the axes of the threaded lead screw pair are always ensured to be coincident.
The detailed description of the present invention is the prior art, and although the present invention has been specifically shown and described in connection with the preferred embodiments, the method and the way of implementing the technical solution are numerous, and it is only the preferred embodiments of the present invention described above, but those skilled in the art should understand that the present invention can be variously changed in form and detail without departing from the spirit and scope of the present invention defined by the appended claims, and the present invention is within the protection scope of the present invention.
