Summary of the invention
The defect existing for above-mentioned prior art, the object of the present invention is to provide a kind of adjustable fixture of clamping thickness that can clamp different size part, and this fixture is not requiring that installation site is very accurate.
For achieving the above object, technical scheme of the present invention is: the adjustable fixture of clamping thickness, comprise mount pad, described mount pad is provided with installing hole, wherein, also be provided with fixed bar, sliding mandril, clamping bar, the dwang of spring and one end strap cam, described fixed bar bottom is provided with external screw thread, top is radially provided with groove and the connecting hole vertical with groove plane, fixed bar is axially arranged with the sliding eye that sliding mandril passes, described cam is positioned at groove, and be rotationally connected by connecting hole and fixed bar, described sliding mandril top coordinates with sliding eye, bottom is provided with screwed hole vertically, described spring is arranged at sliding mandril bottom, two ends are supported on respectively on sliding mandril top and sliding eye, described clamping bar one end and screwed hole are connected.
While adopting technique scheme, between fixed bar and mount pad, be threaded, clamping bar is connected in the screwed hole of sliding mandril bottom, during use, the position of fixed bar in the vertical direction can be regulated, in addition, clamping bar and sliding mandril relative position in the axial direction can also be regulated, thereby can, for the part to be clamped of different size size, regulate the grip thickness of clamping bar.
Further, described sliding mandril upper surface is provided with cam path, during compressing component, pull dwang, cam face and sliding mandril upper surface relative sliding downwards extruding sliding mandril, cam path just can prevent that in use procedure, sliding mandril rotates and skids, and has improved clamping effect.
Further, described cam and dwang removably connect, in use procedure of the present invention, the most easily wearing and tearing is surface and the sliding mandril upper surface of cam friction, and dwang generally can not damage, when cam and dwang removably connect, only need to change cam after cam wear, dwang can continue to use.
Further, described dwang connects footpath, one end and is upwards provided with pin hole, and described cam application of force one end is provided with adapter sleeve, and described adapter sleeve is provided with the spliced eye that described dwang is installed, and the fixing fixing hole of dwang, and this connected mode is convenient to change cam.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the adjustable fixture embodiment of clamping thickness of the present invention;
Fig. 2 is the structural representation of fixed bar in the adjustable fixture embodiment of clamping thickness of the present invention;
Fig. 3 is the structural representation of sliding mandril in the adjustable fixture embodiment of clamping thickness of the present invention;
Fig. 4 is the structural representation that clamping thickness of the present invention adjustable fixture embodiment cam and dwang removably connect.
The specific embodiment
As shown in Figure 1, the adjustable fixture of a kind of clamping thickness, comprise mount pad 1, described mount pad 1 is provided with installing hole 11, wherein, also be provided with fixed bar 2, sliding mandril 3, clamping bar 4, the dwang 5 of spring and one end strap cam 6, described fixed bar 2 bottoms are provided with external screw thread 21, top is radially provided with groove 22 and the connecting hole vertical with groove 22 planes, fixed bar 2 is axially arranged with the sliding eye that sliding mandril 3 passes, described cam 6 is positioned at groove 22, and be rotationally connected by connecting hole and fixed bar 2, described sliding mandril 3 tops coordinate with sliding eye, bottom is provided with screwed hole vertically, described spring is run through by sliding mandril 3 bottoms, two ends are supported on respectively on sliding mandril 3 tops and sliding eye, described clamping bar 4 one end and screwed hole are connected.
In the present invention, between fixed bar 2 and mount pad 1, be threaded, clamping bar 4 is connected in the screwed hole of sliding mandril 3 bottoms, during use, the position of fixed bar 2 in the vertical directions can be regulated, in addition, clamping bar 4 and sliding mandril 3 relative position in the axial direction can also be regulated, thereby can, for the part to be clamped of different size size, regulate the grip thickness of clamping bar 4.
Described sliding mandril 3 upper surfaces are provided with cam path 31, during compressing component, pull dwang 5, cam 6 surfaces and sliding mandril 3 upper surface relative slidings downward extruding sliding mandril 3, cam path 31 just can prevent that in use procedure, sliding mandril 3 rotates and skids, and has improved clamping effect.Described cam 6 removably connects with dwang 5, in use procedure of the present invention, the most easily wearing and tearing is surface and sliding mandril 3 upper surfaces of cam 6 frictions, and dwang 5 generally can not damage, when cam 6 removably connects with dwang 5, after cam 6 wearing and tearing, only need to change cam 6, dwang 5 can continue to use.Described dwang 5 connects footpaths, one end and is upwards provided with pin hole, and described cam 6 application of force one end are provided with adapter sleeve 9, and described adapter sleeve 9 is provided with the spliced eye that described dwang 5 is installed, and the fixing fixing hole of dwang 5, and this connected mode is convenient to change cam 6.
Concrete using method:
By the present invention, with bolt, the installing hole 11 by mount pad 1 is fixed on workbench, after installation, rotation regulates the height of fixed bar 2 vertical direction in mount pad 1, simultaneously, also can regulate the relative position of clamping bar 4 and sliding mandril 3 in the vertical directions, after adjusting completes, respectively by fixed bar nut 7 and 8 lockings of clamping bar nut, part to be processed is positioned on workbench, pull clockwise dwang 5, cam 6 rotates and pushes sliding mandril 3 upper surfaces downwards, sliding mandril 3 moves down, the spring being supported on sliding mandril 3 and mount pad 1 is compressed, sliding mandril 3 promotes clamping bar 4 and clamps part, part completion of processing, pull counterclockwise dwang 5, now, compressed spring recovers, upwards promote sliding mandril 3, clamping bar 4 is also along with moving on sliding mandril 3, unclamp part.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
