Description
Technical Field
The invention relates to the technical field of flatness and parallelism detection of a cast blank, in particular to a platform for detecting the flatness and the parallelism of a heavy-duty car support blank.
Background
The flatness of the workpiece refers to the deviation of the height of macro concave-convex on the surface of the workpiece relative to an ideal plane; the parallelism of the workpiece refers to the degree of parallelism of two planes of the workpiece, and refers to the maximum allowable error value of the parallelism of one plane relative to the other plane, and the parallelism is one of important indexes for evaluating the surface topography of the workpiece. The heavy automobile support is an important auxiliary component of a fire truck engine, and the assembly process is completed by welding by a robot, so that the requirements on the flatness and the parallelism of a blank of the heavy automobile support are higher. In the past, most of the detection of the blank surface is marking detection, and the mode of measuring by a height gauge cannot be met in terms of efficiency and measurement accuracy.
Disclosure of Invention
To the problem that above-mentioned detection efficiency and measurement accuracy are low, the utility model aims at providing a heavy automobile support blank plane degree and depth of parallelism's testing platform, and it is convenient to detect, improves work efficiency and measurement accuracy.
In order to achieve the above object, the utility model adopts the following technical scheme: the detecting platform for the flatness and the parallelism of the support blank of the heavy-duty car comprises a positioning upright column and a detecting device, wherein the positioning upright column and the detecting device are arranged on the detecting platform; the positioning upright posts have the same height and are distributed on the detection platform in a triangular shape according to the outline of the workpiece; the detection device comprises a height gauge turntable, a height gauge, a locking slide block and an L-shaped measuring rod; the bottom of the height gauge turntable is fixed at the edge of the detection platform, and the height gauge is arranged above the height gauge turntable; the L-shaped measuring rod is connected to the height gauge through the locking slide block.
Preferably, the positioning upright column is a contour cone.
The utility model discloses a technological effect and advantage: the height gauge can rotate to measure by adopting a positioning support workpiece and a height gauge turntable, and the height and the length can be adjusted at will according to the profile of the workpiece by utilizing the height gauge, the locking slide block and the L-shaped measuring rod. The detection is more convenient, and the working efficiency and the detection precision are improved.
Drawings
FIG. 1 is the utility model relates to a heavy-duty car support blank plane degree and depth of parallelism's testing platform stereogram.
In figure 1, 1-detection platform, 2-positioning upright post, 3-height gauge turntable, 4-height gauge, 5-L-shaped measuring rod and 6-locking slide block.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Example 1
As shown in figure 1, the detection platform for the flatness and the parallelism of the support blank of the heavy-duty car is characterized in that three positioning upright posts 2 are placed on the detection platform 1, the positioning upright posts are distributed in a triangular mode according to the outline of a workpiece, the support blank of the heavy-duty car is placed on the positioning upright posts 2, the support blank of the heavy-duty car is detected, in the measurement process, a height gauge turntable 3 is utilized, a height gauge 4 is rotated randomly, a locking sliding block 6 and an L-shaped measuring rod 5 are adjusted according to the height and the outline of the placed support blank of the heavy-duty car and matched with each other, the L-shaped measuring rod conducts point taking measurement on the upper surface of the support blank of the heavy-duty car, at least three points are taken, and the measured height value is qualified if the difference of the. The positioning upright post can also be arranged into an isosceles cone and can be in magnetic contact with the detection platform.
While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
