Abstract
The utility model provides a left steering knuckle arm calibration tool. The left steering knuckle arm calibration tool comprises a base plate, wherein a screw hole is formed in the base plate. The left steering knuckle arm calibration tool is fixed on a working platform by a screw when used. A calibration column and a positioning assembly are arranged on the base plate and are located on the two sides of the base plate respectively. The positioning assembly is composed of two horizontal positioning plates which are placed in parallel and a gap is reserved between the two horizontal positioning plates and is used for clamping the steering part of a workpiece. A groove and a positioning hole are formed in the upper portion of the calibration column and in the lower portion of the calibration column respectively and are used for clamping the two ends of the workpiece and limiting the moving direction of the workpiece. According to the left steering knuckle arm calibration tool, a left steering knuckle arm can be well clamped under the combined action of the base plate, the calibration column and the positioning assembly, favorable guarantee is provided for calibration, and waste products are effectively prevented from being produced after hot working.
Description
Technical field
The utility model relates to the means for correcting of automobile left steering joint arm, relates in particular to a kind of left steering joint arm correcting tool.
Background technology
Left steering joint arm complex contour, the structure no regularity, behind the heat treatment quenching and tempering distortion bigger, deflection accounts for more than 75% of sum, it is particularly important that correcting process seems.Traditional correcting tool equipment adopts flat-die hammer and ejection frock to proofread and correct mostly, and this frock operation easier is very big, the non-constant of security, correction efficient is low, and weak effect is once proofreaied and correct qualification rate between 30-50%, the duplication of labour has brought unnecessary artificial, the energy, equipment waste.
The utility model content
The technical problems to be solved in the utility model is in order to overcome technological deficiency recited above, to provide a kind of easy to operate, efficient height, the left steering joint arm correcting tool that security is good.In order to address the above problem, the present invention takes following technical scheme:
A kind of left steering joint arm correcting tool comprises base plate, and a side of this base plate is provided with and proofreaies and correct post, opposite side is provided with locating piece, and described correction column top and bottom arrange groove and locating hole respectively.
Adopt said structure base plate to be positioned on the workbench with screw, groove and locating hole are put in the workpiece two ends, and it is spacing that the turning part cartoon is crossed positioning component, makes it can not move freely on the XYZ direction, improved working (machining) efficiency and correction accuracy.
Described positioning component is two horizontal location-plates that are arranged in parallel.The turning part of workpiece is spacing by being stuck between the two parallel horizontal location-plates,
The axial symmetry line b of the centre symmetry line a of described groove and described locating hole, the projection line of in the vertical direction is not overlapping, and the spacing of 16 ~ 17mm is arranged.
This arrangement requirement can make groove and hole in the vertical direction have certain dislocation relation, thereby adapts to the structure of workpiece, guarantees spacing more reliable.
On the described base plate screw hole is arranged, be used for fixed base plate.
Beneficial effect: the utility model is simple in structure, easy to operate, has strengthened the stability of workpiece in trimming process, thereby has improved correction accuracy, and security is good.
Description of drawings
Fig. 1 is the plan structure schematic diagram of the utility model left steering joint arm correcting tool.
Fig. 2 is the front view of the correction post of Fig. 1.
Among the figure: 1. base plate, 2. proofread and correct post, 3. positioning component, 4. groove, 5. locating hole, 6. screw hole, 7. screw hole.
The specific embodiment
As depicted in figs. 1 and 2, left steering joint arm correcting tool comprises base plate 1, and the edges at two ends middle part, the left and right sides of base plate 1 offers screw hole 6,7.Base plate 1 upper surface one side is provided with proofreaies and correct post 2, and opposite side is provided with positioning component 3.
Described positioning component 3 is two horizontal location-plates, and horizontal parallel and at regular intervals is used for blocking the workpiece turning part; Proofread and correct post 2 bottom surfaces and be welded on the base plate 1, described correction post 2 has center symmetry, the axisymmetric shape of rule, and is preferably cylindrical.The cylinder lower end is provided with locating hole 5, is used for holding an end of left steering joint arm and being fixed; The cylinder end face is provided with groove 4, is used for holding the other end of left steering joint arm and being fixed.
Below the structure of proofreading and correct post 2 is elaborated.
As can be seen from Figure 2,4 two parallel sided of groove, one of them side is positioned at the horizontal direction line of symmetry position of proofreading and correct post 2 just; Locating hole 5 is manhole.
Among Fig. 1, represent the centre symmetry line of groove 4, the axial symmetry line of locating hole 5 with a, b.As can be seen from the figure, the projection of a, b in the vertical direction does not overlap, and spacing is c, and the value of c is different and different according to the workpiece situation, is generally 16 ~ 17 millimeters, but might not belongs to this scope.What deserves to be mentioned is that horizontal direction line of symmetry and two the horizontal location-plates center line at interval of proofreading and correct post 2 are same straight line.Below all be according to the distinctive appearance design of left steering joint arm.
The utility model by the screw hole 6,7 at base plate 1, is fixed on base plate 1 on the work top of milling machine with screw in use; Two horizontal location-plates firmly block the turning part of workpiece, have limited the movement of workpiece on Y-direction; Need an end of the left steering joint arm of milling machine processing to put in the locating hole 5, the other end stretches in the groove 4, has effectively limited the movement of workpiece in the XZ direction.
The present invention is by the restriction free degree of workpiece on the XYZ direction, and proofreading and correct for left steering joint arm provides favourable guarantee, effectively prevents the generation of waste product after the hot-working.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; should be pointed out that all any modifications of within spirit of the present utility model and principle, doing, be equal to replacement and improvement etc., all should be included within the protection domain of the present utility model.
