The utility model discloses hexagonal formula transmission shaft is used in operation lathe transmission replaces traditional sliding key axle with the hexagonal transmission shaft to supporting installation hexagonal cover, and then has improved the fixed area of contact of transmission shaft with the hollow shaft at double, therefore the stand wear ability improves at double, has greatly guaranteed the life of transmission shaft, is fit for being extensively promoted and used.
Description
Technical Field
The utility model relates to an operation lathe drive disk assembly makes technical field, in particular to hexagonal formula transmission shaft is used in transmission of operation lathe.
Background
Most of transmission shafts for existing rolling mill operation machine tools are round sliding key shafts (as shown in figure 2), the transmission shafts are fixedly connected with hollow shafts provided with gears (as shown in figure 1) through L-shaped key pins, and after the transmission shafts are used for a period of time, the positions of key openings are easily worn too fast, so that the transmission shafts are often required to be replaced by new sliding key shafts in a short time, the replacement frequency of the transmission shafts is large, and great burden is brought to labor intensity and economy of people.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides an operation machine tool is hexagonal formula transmission shaft for transmission can effectively solve the problem among the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an operation lathe transmission is with hexagonal formula transmission shaft, includes the lathe, lathe one side is provided with the hollow shaft, and the hollow shaft pass through the axle sleeve install in lathe central point puts, the hexagonal transmission shaft is equipped with in the hollow shaft interpolation, and the hexagonal transmission shaft transversely runs through the hollow shaft, hollow shaft one end still has the hexagonal cover through threaded connection, be clearance fit between hollow shaft outer wall and the hexagonal cover inner wall.
Preferably, the machine tool is characterized in that supporting blocks are further welded on one side of the machine tool, the supporting blocks are multiple in number, bushings are mounted at the bottoms of the supporting blocks through reserved grooves, and the hollow shaft transversely penetrates through the bushings.
Preferably, the front end of the machine tool is further provided with a supporting plate, the bottom of the supporting plate is provided with a bearing through a reserved groove, and the hollow shaft transversely penetrates through the bearing.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses, through at hollow shaft one side threaded connection hexagonal cover to with traditional feather key axle replacement for hexagonal transmission shaft, thereby the area of contact that wears between hexagonal transmission shaft outer wall and the hexagonal cover inner wall improves at double for the area of contact that wears between traditional feather key epaxial keyway and the L shape key round pin, and then has prolonged the life of operation lathe transmission shaft greatly, has reduced the change frequency of operation lathe transmission shaft, has reduced rolling mill operation production economic cost.

Detailed Description
The present invention will be described in further detail with reference to the drawings, wherein like elements are designated by like reference numerals, wherein the terms "front", "rear", "left", "right", "upper" and "lower", "bottom" and "top" used in the following description refer to the orientation in the drawings, and the terms "inner" and "outer" refer to the orientation toward or away from the geometric center of a particular element, respectively.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 3-6, the hexagonal transmission shaft for transmission of the working machine tool comprises a machine tool 1, wherein a hollow shaft 3 is arranged on one side of the machine tool 1, the hollow shaft 3 is mounted at the center of the machine tool 1 through a shaft sleeve 7, a hexagonal transmission shaft 2 is inserted into the hollow shaft 3, the hexagonal transmission shaft 2 transversely penetrates through the hollow shaft 3, one end of the hollow shaft 3 is further connected with a hexagonal sleeve 4 through threads, and the outer wall of the hollow shaft 3 is in clearance fit with the inner wall of the hexagonal sleeve 4.
Referring to fig. 3, in order to support the hollow shaft 3, a plurality of supporting blocks 6 are further welded on one side of the machine tool 1, a bushing 8 is installed at the bottom of each supporting block 6 through a pre-groove, and the hollow shaft 3 transversely penetrates through the bushing 8.
Referring to fig. 3, in order to improve the rotational stability of the hollow shaft 3 connected to the hollow shaft 3, a supporting plate 5 is further disposed at the front end of the machine tool 1, a bearing 9 is mounted at the bottom of the supporting plate 5 through a preformed groove, and the hollow shaft 3 transversely penetrates through the bearing 9.
It should be noted that, the utility model relates to a hexagonal transmission shaft for transmission of an operation machine tool, when in work, a person installs the thread of a hexagonal sleeve 4 at one end of a hollow shaft 3, inserts a hexagonal transmission shaft 2 into the hollow shaft 3 by passing the hexagonal sleeve 4 transversely, and finally connects one end of the hexagonal transmission shaft 2 with an operation machine tool driving part; in the process of production operation of an external driving mechanism through a hexagonal transmission shaft 2 to drive a machine tool, due to the fact that the abrasion contact area between the outer wall (six faces) of the hexagonal transmission shaft 2 and the inner wall of a hexagonal sleeve 4 is increased in a multiplied mode relative to the abrasion contact area between a key groove and an L-shaped key pin 11 on a traditional sliding key shaft 10, the service life of the transmission shaft of the operation machine tool is greatly prolonged, the replacement frequency of the transmission shaft of the operation machine tool is reduced, and the economic cost of operation production of a rolling mill is reduced.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
