Abstract
The invention relates to the technical field of caterpillar link clamp machining and particularly relates to a fixing shifting fork for caterpillar links. The fixing shifting fork comprises a shifting fork shank, a shifting fork shaft and a U-shaped shifting fork claw. Protrusions are arranged at ends of the shifting fork claw, the shifting fork shaft is fixed below the shifting fork claw eccentrically and perpendicularly, and the shifting fork shank is connected with the shifting fork shaft. According to the fixing shifting fork, the fixing shifting fork comprises the shifting fork shank, the shifting fork shaft and the shifting fork claw, the shifting fork claw is U-shaped, to that a workpiece can be tightly pressed, tool crashing caused by the fact that the workpiece cannot be pressed tightly is effectively prevented; the protrusions are arranged at ends of the shifting fork claw, so that abrasion of the ends of the shifting fork claw is prevented, and the service life is prolonged; the shifting fork shaft is fixed below the shifting fork claw eccentrically and perpendicularly, and the shifting fork shank is connected with the shifting fork shaft, so that the fixing shifting fork is reasonable in structural design, small in size and simple to exchange and operate.
Description
Technical field
The present invention relates to machining chain rail joint clamp technology field, relate in particular to fixedly shift fork of a kind of chain rail joint.
Background technology
In chain rail joint jig Design, there is no at first shifting fork structure, but through long-term processed and applied practice, it is found that chain rail joint has outward-dipping trend when putting part, even put workpiece and just directly outwards fall, if workpiece outwards falls, turning arm is correct workpiece pressing just, thereby produce and hit cutter, the danger such as quality accident even occur.In order to overcome this problem, occurred effectively preventing that the chain rail that workpiece is outwards toppled over from saving fixedly shift fork, but the termination of the shift fork claw of this kind of shift fork contacts with workpiece, the abutment pressure of this termination contact is large, easily be worn and even ftracture, fixedly shift fork is short service life to cause chain rail joint.
Summary of the invention
The object of the invention is to propose fixedly shift fork of a kind of chain rail joint, solve the end that has the shift fork claw now the short problem in service life of easily wearing and tearing.
For reaching this purpose, the present invention by the following technical solutions:
A kind of chain rail joint is shift fork fixedly, comprise shift fork handle, declutch shift shaft and shift fork claw, described shift fork claw is the U-shaped structure, and the end of described shift fork claw is provided with projection, described declutch shift shaft bias is vertically fixed on the below of shift fork claw, and described shift fork handle is connected with declutch shift shaft.
Preferably, described projection is arranged on the inboard of shift fork claw end.
Preferably, described projection is with chamfering.
Preferably, the afterbody of described shift fork handle has installing hole.
Preferably, the thickness of described shift fork handle is less than the thickness of declutch shift shaft.
Preferably, the afterbody of described declutch shift shaft is circular arc.
Preferably, described shift fork handle, declutch shift shaft and shift fork claw adopt silumin to make.
Chain rail joint of the present invention fixedly shift fork comprises shift fork handle, declutch shift shaft and shift fork claw, the shift fork claw is the U-shaped structure, can workpiece pressing, and effectively avoid the workpiece can not be compacted and cutter occurs hitting, the end of shift fork claw is provided with projection, prevent the end wear of shift fork claw, increase service life, declutch shift shaft bias is vertically fixed on the below of shift fork claw, the shift fork handle is connected with declutch shift shaft, reasonable in design, volume is little, changes simple to operate.
The accompanying drawing explanation
Fig. 1 is the fixedly front view of shift fork of chain rail joint;
Fig. 2 is fixedly the fork axle of shift fork and the left view of fork handle of chain rail joint.
In figure, 1 shift fork handle, 2 declutch shift shafts, 3 shift fork claws, 4 installing holes, 5 projections.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
See Fig. 1 Fig. 2, a kind of chain rail joint of the present embodiment is shift fork fixedly, comprise shift fork handle 1, declutch shift shaft 2 and shift fork claw 3, shift fork claw 3 is the U-shaped structure, the end of described shift fork claw 3 is provided with projection 5, described declutch shift shaft 2 bias are vertically fixed on the below of shift fork claw 3, and described shift fork handle 1 is connected with declutch shift shaft 2.
By shift fork claw 3 is designed to the U-shaped structure, the end of shift fork claw 3 contacts with workpiece, and abutment pressure herein is large, can workpiece pressing, effectively avoid the workpiece can not be compacted and cutter occurs hitting, avoid its flare simultaneously, the end of shift fork claw 3 is provided with projection 5, prevent the end wear of shift fork claw 3, increase service life, declutch shift shaft 2 bias are vertically fixed on the below of shift fork claw 3, shift fork handle 1 is connected with declutch shift shaft 2, reasonable in design, volume is little, changes simple to operate.
As the preferred embodiments of the present invention, projection 5 is arranged on the inboard of shift fork claw 3 ends.The end of shift fork claw 3 contacts with workpiece respectively, the abutment pressure of contact is large herein, the inboard of shift fork claw 3 ends is groundwork faces, during the shift fork rotation, the inboard of shift fork claw 3 ends contacts with workpiece, and easily wearing and tearing, be provided with protruding 5 structures in the inboard of shift fork claw 3 ends, inner bulge 5 structures of wearing and tearing shift fork claw 3 ends during shift fork work, the service life of growth shift fork.Preferably, projection 5 is with chamfering, and when the design of chamfering structure avoids protruding 5 sharp edges to cause work, noise is large, also avoids being scratched simultaneously.
As another preferred embodiment of the present invention, the afterbody of shift fork handle 1 has installing hole 4.
As another preferred embodiment of the present invention, the thickness of shift fork handle 1 is less than the thickness of declutch shift shaft 2.
As another preferred embodiment of the present invention, the afterbody of declutch shift shaft 2 is circular arc.
The afterbody of shift fork handle 1 has installing hole 4, and the thickness of shift fork handle 1 is less than the thickness of declutch shift shaft 2, and the afterbody of declutch shift shaft 2 is circular arc, with the junction of declutch shift shaft 2, forms arch steps, is convenient to the shift fork rotation, is convenient to install.
Chain rail joint is the operation principle of shift fork fixedly: in behind dawn, hole of chain rail joint, coordinate with spring fixedly shift fork of chain rail joint is installed, in the course of the work, after chain rail joint workpiece is installed, chain rail joint Work-sheet pressing shift fork, shift fork prevents that by reaction force workpiece from outwards toppling over, avoid chain rail joint outwards to topple over, thereby the prevention workpiece can not be compacted and the problem such as cutter accident occurs hitting.
As another preferred embodiment of the present invention, described shift fork handle 1, declutch shift shaft 2 and shift fork claw 3 adopt silumin to make.
