Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the technical field of hydraulic pressure base plate is adjusted, especially, relate to a hydraulic pressure base adjusting screw mechanism.
[ background of the invention ]
When the hydraulic mechanism is installed, the hydraulic mechanism is generally arranged on a base, and in order to guarantee the installation accuracy of the hydraulic mechanism, the height of the base is usually adjusted by arranging the base into a structure which can be finely adjusted up and down. In the prior art, the space of the adjusting structure of the hydraulic mechanism base occupies a large area, the mechanism configuration is not facilitated in an area with limited space, the height adjusting range is limited, the installation requirement is high, and the height balance adjustment is difficult.
Therefore, there is a need to provide a new hydraulic base adjustment screw mechanism to solve the above problems.
[ Utility model ] content
The utility model discloses a main aim at provides a hydraulic pressure base adjusting screw mechanism, compact structure, the space occupies for a short time, can realize heavily loaded lathe lower margin altitude mixture control and locking, and adjustable range is up to 30 mm.
The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a hydraulic pressure base adjusting screw mechanism, its includes lower floor's bottom plate, is located the upper floor of lower floor's bottom plate top, passes the upper floor and in the lower extreme with lower floor's bottom plate threaded connection's interior screw, cover are established interior screw is last and the lower extreme is supported and is being held outer screw on lower floor's bottom plate surface, set up through threaded connection outer screw is last and will the big nut that upper floor's bottom plate shrank, set up through threaded connection interior screw is last and will outer screw crimple's little nut, the upper floor with outer screw threaded connection, through rotatory outer screw can realize the upper and lower altitude mixture control of upper floor's bottom plate.
Furthermore, the outer screw, the upper bottom plate and the lower bottom plate are tightened by the matching of the inner screw and the small nut.
Furthermore, the outer screw is matched with the large nut to shrink the upper-layer bottom plate downwards.
Further, the outer screw and the inner screw can move axially relative to each other.
Furthermore, a threaded hole is formed in the lower-layer bottom plate, and external threads matched with the threaded hole are arranged at the lower end of the inner screw.
Compared with the prior art, the utility model relates to a hydraulic pressure base adjusting screw mechanism's beneficial effect lies in: the structure is compact, the occupied space is small, the height adjustment and locking of the foot margin of the heavy-duty machine tool can be realized, and the adjustable range is up to 30 mm; the mechanism has high integrity and stable structure after adjustment.
[ description of the drawings ]

FIG. 2 is a schematic cross-sectional view of an embodiment of the present invention;
the figures in the drawings represent:
100 hydraulic base adjusting screw mechanism;
1, a lower bottom plate; 2, an upper layer soleplate; 3, internal screws; 4, external screw; 5, a large nut; 6 small nuts.
[ detailed description ] embodiments
Example (b):
referring to fig. 1-2, the present embodiment is a hydraulic base adjusting screw mechanism 100, which includes a lower bottom plate 1, an upper bottom plate 2 located above the lower bottom plate 1, an inner screw 3 passing through the upper bottom plate 2 and being in threaded connection with the lower bottom plate 1 at a lower end, an outer screw 4 sleeved on the inner screw 3 and having a lower end abutting against the surface of the lower bottom plate 1, a large nut 5 disposed on the outer screw 4 through threaded connection and tightening the upper bottom plate 2, a small nut 6 disposed on the inner screw 3 through threaded connection and tightening the outer screw 4, the upper bottom plate 2 being in threaded connection with the outer screw 4, and the upper and lower height adjustment of the upper bottom plate 2 being achieved by rotating the outer screw 4.
The outer screw 4, the upper-layer bottom plate 2 and the lower-layer bottom plate 1 are tensioned by the matching of the inner screw 3 and the small nut 6. The outer screw 4 is prevented from sliding up and down to influence the adjusting precision. After the adjustment is finished, the upper bottom plate 2 can be prevented from jumping along with the outer screws 4 by realizing the shrinkage through the small nuts 6.
The outer screw 4 is matched with the large nut 5 to shrink the upper-layer bottom plate 2 downwards.
The outer screw 4 and the inner screw 3 can move axially relative to each other.
The upper layer bottom plate 2 is used for supporting the hydraulic cylinder body to be installed.
A threaded hole is formed in the lower-layer bottom plate 1, and external threads matched with the threaded hole are arranged at the lower end of the inner screw 3.
The hydraulic base adjusting screw mechanism 100 is compact in structure and small in occupied space, the height of a heavy-duty machine tool foot can be adjusted and locked, and the adjustable range is up to 30 mm; the mechanism has high integrity and stable structure after adjustment.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
