Technical Field
The utility model relates to an unsmooth platform measuring tool of tang belongs to machining and assembly auxiliary assembly technical field.
Background
In the machining and assembling processes, a plurality of parts need to be positioned by using rabbets to ensure the assembling precision. Thus, the accuracy of the spigot will directly affect the accuracy of the post-assembly, and the dimensions and accuracy of the spigot-mating bosses and bosses in the process need to be precisely controlled. It is common for the precision control of the spigot-recess boss to be governed by measurements during machining.
At present, for a spigot concave station with the depth of more than 10mm, an inner diameter dial indicator can be used for direct measurement, but for the spigot concave station with the station depth of less than 10mm, the measurement can only be carried out by using a three-coordinate measuring machine because a ruler body of the inner diameter dial indicator is interfered with a workpiece and cannot be measured; similar to the seam allowance concave station, for the seam allowance convex station with the station depth larger than 8mm, the outside micrometer can be used for direct measurement, however, for the seam allowance convex station with the station depth smaller than 8mm, because the spiral micrometer cylinder of the outside micrometer is interfered with the workpiece and cannot be measured, the measurement can only be carried out through a three-coordinate measuring machine. However, when the three-coordinate measuring machine is used for measurement, the spigot boss and the spigot recess table need to be measured after the workpiece is subjected to constant temperature, so that certain delay exists in the timeliness of measurement and inspection, the measurement efficiency is affected, and the cost caused by the use of the three-coordinate measuring machine is high.
The defects of the prior art are overcome.
Disclosure of Invention
For the not enough in the technique above solving, the utility model provides an unsmooth platform measuring tool of tang can measure the size precision whether shallow boss of tang and the shallow concave platform of tang meet the requirements with lower cost fast.
The technical scheme of the utility model as follows: a spigot concave-convex platform measuring tool comprises a spigot boss measuring part and a spigot concave platform measuring part, wherein the spigot boss measuring part comprises a boss ruler frame, a first adjusting measuring anvil and a second adjusting measuring anvil are oppositely arranged at the end part of the boss ruler frame, and a standard gauge head is also arranged at the end part of the boss ruler frame; the spigot concave platform measuring piece comprises a concave platform ruler frame, one end of the concave platform ruler frame is provided with an adjustable measuring anvil, and the other end of the concave platform ruler frame is provided with a standard gauge head; the zero numerical value of the gauge head of the standard calibration gauge is the dimension of a spigot boss or a spigot concave table which is measured in advance, and the first adjusting anvil, the second adjusting anvil and the adjustable anvil are in straight rod shapes.
The technical scheme of the utility model still include: the concave bench ruler frame is connected with the adjustable measuring anvil through threads, and the locking nut and the adjusting nut are installed at the thread position.
The technical scheme of the utility model still include: the concave bench ruler frame is in a straight rod shape.
The technical scheme of the utility model still include: the boss ruler frame is semicircular, two ends of the boss ruler frame are oppositely arranged, and the first adjusting measuring anvil and the second adjusting measuring anvil are respectively located at two ends of the boss ruler frame.
The utility model has the advantages that: by respectively installing standard gauge heads which take the sizes of the spigot boss and the spigot recess table which are measured in advance as zero values on the spigot boss measuring piece and the spigot recess table measuring piece, namely providing a basic zero position during measurement, and arranging a measuring rod which is in contact with a workpiece into a straight rod-shaped first adjusting anvil, a second adjusting anvil and an adjustable anvil, when measuring the shallow spigot boss and the spigot recess table with smaller sizes, the diameters of the shallow spigot boss and the spigot recess table can be measured only by aligning the first adjusting anvil and the second adjusting anvil to the outer diameter of the shallow spigot boss or placing the adjustable anvil into the spigot recess table, and then by comparing the difference value of the standard gauge heads and the apparent difference value of the gauge heads, the waiting of the temperature condition of the workpiece is avoided, the high cost of using a three-coordinate measuring machine is avoided, and the size of the spigot recess table can be measured quickly and accurately, to ensure dimensional accuracy of subsequent assembly.
