Description
Technical field
The utility model relates to driving or the transmission device of a kind of grinding machine or device, is specifically related to a kind of feed screw backlash compensation structure.
Background technology
Sheet metal component is exactly the product that sheet metal process processes, and we be unable to do without sheet metal component everywhere at life.Sheet metal component fetches making by filament supply winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cut, precision welding, rolling and forming, sheet metal brake forming, die forging, water injection cutting, precision welding.Along with the application of panel beating is more and more extensive, the design of sheet metal component becomes a ring very important in product development process, mechanical engineer skillfully must grasp the design tactics of sheet metal component, make the panel beating designed both meet the requirements such as the function of product and outward appearance, can make again that diel manufacture is simple, cost is low.
A large amount of sheet metal components is used in automobile manufacturing process, automobile metal plate work is offered usually with many installing holes for assembling, in the process of boring, often by leading screw feeding, be fixed on by sheet metal component hole to be drilled on feeding seat, feeding seat is connected with threads of lead screw, the feeding of rotational lead screw just adjustable sheet metal component, but have gap between feeding seat and leading screw, so position that sheet metal component is holed can be caused inaccurate.
Utility model content
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of feed screw backlash compensation structure eliminating gap between feeding seat and leading screw.
For achieving the above object, the technical solution of the utility model is:
Feed screw backlash compensation structure, comprise body, leading screw and feeding seat, described leading screw and body are rotationally connected, feeding seat is connected with threads of lead screw, described feeding seat is provided with the hold-down apertures of fixing sheet metal component, wherein, also be provided with pressurizing nut, pressing spring and bolt, described pressurizing nut and feeding seat are equipped with ring flange, pressurizing nut is connected with threads of lead screw, ring flange on ring flange on pressurizing nut and feeding seat is adjacent, two ring flanges are at least connected by two described bolts, one end of two bolt homonymies is all arranged with described pressing spring, ring flange on pressing spring one end and pressurizing nut offsets, the other end is compressed by nut.
When adopting technique scheme, first sheet metal component to be processed is fixed on feeding seat, because feeding seat is all connected with threads of lead screw with pressurizing nut, and feeding seat and pressurizing nut are equipped with ring flange, and connected by least two bolts between two ring flanges, one end of two bolt homonymies is all arranged with described pressing spring, ring flange on pressing spring one end and pressurizing nut offsets, the other end is compressed by nut, so under the effect of pressing spring, produce mutually between pressurizing nut and feeding seat and be pressed against effect, thus the gap of eliminating between feeding seat and leading screw, like this when holing, feeding seat can not offset, so the sheet metal component be fixed on feeding seat also would not be moved, thus ensure that bore position is accurate.The utility model sets up pressurizing nut, screw rod and pressing spring, is connected by pressurizing nut with screw rod with feeding seat, under the effect of pressing spring, just can eliminate the minim gap of feeding seat and leading screw part, ensures the accuracy of sheet metal component boring.
Further, described leading screw is arranged on body by thrust bearing.The first, the wearing and tearing in use between leading screw and body can be reduced; The second, feeding seat and pressurizing nut apply axial force on leading screw, and thrust bearing then can prevent leading screw from moving vertically.
Further, described leading screw one end is provided with handwheel.By hand wheel rotating leading screw, regulate sheet metal component feeding process more laborsaving.
Further, described bolt is stud, and stud one end is threaded with the ring flange of feeding seat.The mode of this connection is simple.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model feed screw backlash compensation structure embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: body 1, nut 2, pressing spring 3, sheet metal component 4, hold-down apertures 5, feeding seat 6, pressurizing nut 7, thrust bearing 8, leading screw 9, handwheel 10.
As shown in Figure 1, a kind of feed screw 9 backlash compensation structure, comprise body 1, leading screw 9 and feeding seat 6, leading screw 9 and body 1 are rotationally connected, feeding seat 6 is threaded with leading screw 9, feeding seat 6 is provided with the hold-down apertures 5 of fixing sheet metal component 4, wherein, also be provided with pressurizing nut 7, pressing spring 3 and bolt, pressurizing nut 7 and feeding seat 6 are equipped with ring flange, pressurizing nut 7 is threaded with leading screw 9, ring flange on ring flange on pressurizing nut 7 and feeding seat 6 is adjacent, two ring flanges are connected by two bolts, one end of two bolt homonymies is all arranged with pressing spring 3, ring flange on pressing spring 3 one end and pressurizing nut 7 offsets, the other end is compressed by nut 2.
In the present embodiment, leading screw 9 is arranged on body 1 by thrust bearing 8.The first, the wearing and tearing in use between leading screw 9 and body 1 can be reduced; The second, feeding seat 6 and pressurizing nut 7 apply axial force on leading screw 9, and thrust bearing 8 can prevent leading screw 9 from moving vertically.
Leading screw 9 one end is provided with handwheel 10.By handwheel 10 rotational lead screw 9, regulate sheet metal component 4 feeding process more laborsaving.
Bolt is stud, and stud one end is threaded with the ring flange of feeding seat 6.The mode of this connection is simple.
Specific works principle:
First sheet metal component 4 to be processed is fixed on feeding seat 6, because feeding seat 6 and pressurizing nut 7 are all threaded with leading screw 9, and feeding seat 6 and pressurizing nut 7 are equipped with ring flange, and connected by least two bolts between two ring flanges, one end of two bolt homonymies is all arranged with described pressing spring 3, ring flange on pressing spring 3 one end and pressurizing nut 7 offsets, the other end is compressed by nut 2, so under the effect of pressing spring 3, produce mutually between pressurizing nut 7 and feeding seat 6 and be pressed against effect, thus the gap of eliminating between feeding seat 6 and leading screw 9, like this when holing, feeding seat 6 can not offset, so the sheet metal component 4 be fixed on feeding seat 6 also would not be moved, thus ensure that bore position is accurate.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
