Abstract
The utility model provides a kind of hold-down gear based on hollow shaft, including chuck, bottom, double threaded screw, gland；Chuck bottom center position is provided with groove, and for discoid installation in a groove, bottom center position has hole to the bottom；The double threaded screw is fixed in passing perpendicularly through the hole that bottom hits exactly；The gland is discoid, hole of the double threaded screw top through gland center.The utility model can process the endoporus of part, cylindrical merging in a machine tool, clamped one time ensures the concentricity of part inside and outside circle, reduce the occupancy of lathe, improve the service efficiency of lathe, and significantly reduce the labour intensity of operator, both processing cost is reduced, frock manufacturing cost is reduced.
Description
Technical field
The utility model is related to a kind of hold-down gear based on hollow shaft.
Background technology
At present, part carries out clamping processing using chuck and special tooling, and again some in particular cases, Dan Shisi
Dog chuck or dress frock clamping parts cannot meet the mistake positioning requirements of part processing, therefore, in this case, it is necessary to a kind of
Cross the frock of positioning to meet the processing request of part, and obtain through refining special tooling again or be transformed on original special tooling full
During the new frock that foot is required, not only the manufacturing cycle is long, and generates huge expense, therefore, this compression based on hollow shaft
Device not only substantially reduces the cycle of manufacture, even more greatly reduces the manufacturing cost of enterprise.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of hold-down gear based on hollow shaft, should be based on sky
The hold-down gear of heart axle can mitigate operator's labour intensity, realize the coherent, reliable clamping of part processing, improve part processing effect
Rate.
The utility model is achieved by the following technical programs.
The utility model provide a kind of hold-down gear based on hollow shaft, including chuck, bottom, double threaded screw,
Gland；Chuck bottom center position is provided with groove, and the bottom is installed in a groove for discoid, the positive middle position of bottom
It is equipped with hole；The double threaded screw is fixed in passing perpendicularly through the hole that bottom hits exactly；The gland is discoid, and double threaded screw top is worn
The hole at overpressure cap center.
Bottom bottom center position is fixed with nut, and double threaded screw is consolidated by the nut that bottom bottom hits exactly with bottom
It is fixed.
The nut-welding of the bottom bottom center is on bottom.
Top and the nut screw thread that there is nut, double threaded screw the gland top surface center coordinate.
The double threaded screw with diameter greater than equal to nut to edge lengths.
The beneficial effects of the utility model are：The endoporus of part, cylindrical merging can be processed in a machine tool, once filled
Folder ensures the concentricity of part inside and outside circle, reduces the occupancy of lathe, improves the service efficiency of lathe, and significantly reduces operation
The labour intensity of person, both reduces processing cost, reduces frock manufacturing cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- chucks, 2- bottoms, 3- double threaded screws, 4- glands, 5- nuts, 6- processing parts.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
A kind of hold-down gear based on hollow shaft as shown in Figure 1, including chuck 1, bottom 2, double threaded screw 3, pressure
Lid 4；The bottom center position of the chuck 1 is provided with groove, and for discoid installation in a groove, bottom 2 hits exactly the bottom 2
There is hole position；The double threaded screw 3 is fixed in passing perpendicularly through the hole that bottom 2 hits exactly；The gland 4 is discoid, double threaded screw 3
Hole of the top through the center of gland 4.
The bottom center position of the bottom 2 is fixed with nut, nut and bottom that double threaded screw 3 is hit exactly by the bottom of bottom 2
Lid 2 is fixed.
The nut-welding of the bottom of the bottom 2 center is on bottom 2.
Top and the screw thread of nut 5 that there is nut 5, double threaded screw 3 top surface of the gland 4 center coordinate.
The double threaded screw 3 with diameter greater than equal to the nut 5 to edge lengths.
When using：Before clamping processing part 6, bottom 2 is first positioned over the bottom of chuck 1, part is processed on clamping
6, after complete endoporus to be processed and face size, double threaded screw 3 is connected into bottom 2, gland 4 is placed in the processing end face of part 6, then with pulling
Hand tightening nuts 5, fixed processing part 6, processing excircles to size.
Thus, the endoporus of part 6, cylindrical merging will be processed to be processed in a machine tool, clamped one time ensures part inside and outside circle
Concentricity, reduce the occupancy of lathe, improve the service efficiency of lathe, and significantly reduce the labour intensity of operator, both
Processing cost is reduced, frock manufacturing cost is reduced, the clamping Contrast on effect such as table 1 with prior art：
The technology of table 1 is compared and had the advantage that or good effect
