Summary of the invention:
The purpose of this utility model is to provide a kind of processing rational in infrastructure, easy, the compressor arm saddle reducing use cost and feeding crank assemblies.
The utility model is achieved in that
A kind of compressor arm saddle and feeding crank assemblies, include compressor arm saddle, feeding crank, one end of compressor arm saddle and one end of feeding crank hinged, one end of compressor arm saddle is provided with screwed hole, one end of feeding crank is provided with through hole, stud pin is screwed onto in the screwed hole of compressor arm saddle through the through hole of feeding crank, and described feeding crank swings around stud pin.
In technique scheme, described feeding crank is also provided with two screwed holes, is screwed onto respectively in corresponding screwed hole for the axial screw installing long pendulum presser bar and presser feet feeding crank connecting link.
In technique scheme, the L-shaped or triangle of described feeding crank.
In technique scheme, described stud pin be cylindrical one end is provided with screw thread, the other end forms convex edge, be outward extended with the shank with cylinder coaxial line in the upper plane of convex edge, described feeding crank rotates around cylinder, and spacing between compressor arm saddle and convex edge.
In technique scheme, described convex edge is kidney-shaped convex edge.
In technique scheme, described feeding crank is made up of 15 chrome molybdenums.
The advantage that the utility model is given prominence to compared to existing technology is:
1, the utility model compressor arm saddle, feeding crank are connected by stud pin, and feeding crank rotates around the cylinder of stud pin, continue to use by changing stud pin upon wear, greatly reduce use cost, long service life, and compressor arm saddle, feeding crank in prior art, can only be scrapped simultaneously, use cost is high;
2, the utility model structure is more reasonable, feeding crank grinding machine flat surface grinding, processing is more simple, convenient, and grinding machine can grind about 200 simultaneously, compare and prior art, except processing plane, also projection will be processed, complex procedures, can only process one by one, substantially increase production efficiency, reduce human cost, machining accuracy is high simultaneously, qualification rate is high;
3, the utility model feeding crank adopts 15 chrome molybdenum materials to make, and than adopting in prior art, 20 chromium materials are more wear-resisting, extend service life.
Accompanying drawing illustrates:
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is exploded perspective view of the present utility model;
Fig. 3 is the schematic diagram after the utility model installs long pendulum presser bar and presser feet feeding crank connecting link;
Fig. 4 is the schematic diagram of feeding crank of the present utility model;
Fig. 5 is the schematic diagram of compressor arm saddle of the present utility model.
Detailed description of the invention:
With specific embodiment, the utility model is further described below, see Fig. 1-5:
A kind of compressor arm saddle and feeding crank assemblies, include compressor arm saddle 1, feeding crank 2, one end of compressor arm saddle 1 and one end of feeding crank 2 hinged, one end of compressor arm saddle 1 is provided with screwed hole 3, one end of feeding crank 2 is provided with through hole 4, stud pin 5 is screwed onto in the screwed hole 3 of compressor arm saddle 1 through the through hole 4 of feeding crank 2, and described feeding crank 2 swings around stud pin 5.One end that compressor arm saddle 1 of the present utility model is provided with screwed hole 3 thickeies 1.5mm-2mm than prior art, makes the depth down of screwed hole 3, and stud pin 5 connects more firm.
Above-mentioned feeding crank 2 is also provided with two screwed holes, is screwed onto respectively in corresponding screwed hole for the axial screw 8,9 installing long pendulum presser bar 6 and presser feet feeding crank connecting link 7.Cylindrical portion around axial screw 8,9 after length puts presser bar 6 and the installation of presser feet feeding crank connecting link 7 swings, undertaken spacing by the head of axial screw 8,9 and feeding crank 2, prevent long pendulum presser bar 6 and presser feet feeding crank connecting link 7 from producing axial displacement along axial screw 8,9.After generation wearing and tearing, reuse by changing stud pin 5, without the need to scrapping compressor arm saddle 1, feeding crank 2, namely compressor arm saddle 1, feeding crank 2 are reusable, reduce use cost.
