Bolt pass through the first connecting hole after with the first screw hole；
The side of the pressing plate is equipped with the block for preventing the crankshaft-link rod transverse shifting to milling, the block and bottom
Plate is fixedly connected.
It advanced optimizes, the block is equipped at least one second connecting hole, and the bottom plate is equipped with and the second connecting hole
Corresponding several the second transversely arranged threaded holes.
It advanced optimizes, the bottom plate is additionally provided with mounting groove, and the crankshaft-link rod includes big end and small end of connecting rod, institute
State mounting groove include two respectively with the matched big annular groove of big end and small end of connecting rod and small annular groove.
It advanced optimizes, the groove depth of the big annular groove and small annular groove is not less than big end respectively and small end of connecting rod is high
The 1/3 of degree.
It advanced optimizes, the two sides of the bottom plate are equipped with the engaging lug connecting with workbench, and the engaging lug is equipped with
Connecting hole for connection.
Beneficial effects of the present invention: when carrying out Milling Process to crankshaft-link rod, crankshaft-link rod is put into two pressing plates
Bolt is being tightened to compress crankshaft-link rod in lower section, while the setting of block can prevent crankshaft-link rod in the process of milling
Middle transverse shifting, influences machining accuracy, so that crankshaft-link rod is placed more stable, has structure simple, clamps stable excellent
Point.
Detailed description of the invention
The present invention is further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of embodiment.
Specific embodiment
Crankshaft-link rod milling fixture as shown in Figure 1 is filled including horizontally disposed bottom plate 1, the compression being located on bottom plate 1
It sets；
Pressing device includes two compressing units being oppositely arranged, and each compressing unit includes pressing plate 21 and bolt 22,
One end that two pressing plates 21 deviate from is extended downwardly to be fixedly connected with bottom plate 1, and the other end is extended downwardly forms clamping between bottom plate 1
Chamber, pressing plate 21 are equipped with the first connecting hole 211, and bottom plate 1 is equipped with first threaded hole corresponding with the first connecting hole 211, bolt
22 pass through the first connecting hole 211 after with the first screw hole；
The side of pressing plate 21 is equipped with the block 4 for preventing 3 transverse shifting of crankshaft-link rod to milling, block 4 and bottom plate 1
It is fixedly connected.
When carrying out Milling Process to crankshaft-link rod 3, crankshaft-link rod 3 is put into two pressing plates, 21 lower section, is tightening spiral shell
Bolt 22 is to compress crankshaft-link rod 3, while the setting of block 4 can prevent crankshaft-link rod 3 from laterally moving during milling
It is dynamic, machining accuracy is influenced, so that the placement of crankshaft-link rod 3 is more stable.
Block 4 is equipped at least one second connecting hole 41, and bottom plate 1 is equipped with several transverse directions corresponding with the second connecting hole 41
Second threaded hole of arrangement.
Block 4 can be connect by the second threaded hole with different location, the position of block 4 be adjusted, to facilitate placement
The crankshaft-link rod 3 of different-diameter size, improves the versatility of fixture.
In order to further increase the stability of fixture clamping crankshaft-link rod 3, mounting groove, crankshaft-link rod 3 are additionally provided in bottom plate
Including big end and small end of connecting rod, mounting groove include two respectively with big end 31 and the matched big annular of small end of connecting rod 32
Slot and small annular groove.The big end 31 of crankshaft-link rod 3 and small end of connecting rod 32 are individually placed to big annular groove and small annular groove, it can
It is clamped with crankshaft-link rod 3 tighter.
Further, the groove depth of big annular groove and small annular groove is not less than 32 height of big end 31 and small end of connecting rod respectively
