Description

A measuring tool for spigot concave and convex table

technical field

The utility model relates to a measuring tool for a spigot concave and convex table, which belongs to the technical field of mechanical processing and assembling auxiliary equipment.

Background technique

In the process of machining and assembly, many parts need to use spigot positioning to ensure the accuracy of assembly. Therefore, the precision of the spigot will directly affect the accuracy of the later assembly, and the size and precision of the bosses and concave platforms that the spigot fits in during processing needs to be precisely controlled. Commonly, the precision control of the spigot concave and convex table is controlled by the measurement during the processing.

At present, the inner diameter dial indicator can be used to directly measure the recessed table with a depth of more than 10mm. However, for the recessed table with a table depth of less than 10mm, due to the interference between the ruler of the inner diameter indicator and the workpiece, it can only be measured. Use a coordinate measuring machine to measure; similar to the spigot concave platform, for the spigot boss with a platform depth greater than 8mm, an outer micrometer can be used to measure directly, but for the spigot boss with a platform depth less than 8mm, the outer diameter of the boss can be measured directly. Due to the interference between the spiral micrometer cylinder of the outer micrometer and the workpiece cannot be measured, it can only be measured by a three-coordinate measuring machine. However, no matter whether the spigot boss or the spigot concave platform is used to measure with a CMM, the workpiece needs to be kept at a constant temperature before it can be measured. Therefore, there is a certain delay in the timeliness of measurement and inspection, which affects the measurement efficiency. And the cost of using a CMM is relatively high.

The above are the shortcomings of the prior art.

SUMMARY OF THE INVENTION

In order to solve the above technical deficiencies, the utility model provides a measuring tool for the spigot concave and convex platform, which can quickly measure whether the spigot shallow convex platform and the spigot shallow concave platform meet the required dimensional accuracy at low cost.

The technical scheme of the present utility model is as follows: a measuring tool for the spigot concave and convex platform, comprising a spigot boss measuring piece and a spigot concave platform measuring piece, and the spigot boss measuring piece includes a convex platform ruler frame, a convex platform ruler frame A first adjustment anvil and a second adjustment anvil are oppositely arranged at the end of the measuring anvil, and the end of the convex platform ruler frame is also provided with a standard calibration gauge head; One end of the table ruler frame is provided with an adjustable measuring anvil, and the other end of the concave table ruler frame is provided with a standard calibration gauge head; size, the first adjustment anvil, the second adjustment anvil and the adjustable anvil are in the shape of straight rods.

The technical scheme of the utility model further comprises: the concave table ruler frame and the adjustable measuring anvil are connected by threads, and a locking nut and an adjusting nut are installed at the thread position.

The technical scheme of the utility model further comprises: the concave table ruler frame is in the shape of a straight rod.

The technical scheme of the utility model further comprises: the boss ruler frame is in the shape of a semi-circle, the two ends of the boss ruler frame are oppositely arranged, and the first adjustment anvil and the second adjustment measurement anvil are respectively located at the two ends of the boss ruler frame .

The beneficial effect of the utility model is: by installing the standard calibration gauge head, which has taken the pre-measured dimensions of the spigot boss and the spigot concave as the zero value, respectively on the spigot boss measuring piece and the spigot concave measuring piece , that is, the basic zero position during measurement is provided, and the measuring rod in contact with the workpiece is set as a straight rod-shaped first adjustment anvil, a second adjustment anvil and an adjustable anvil. When the shallow stop boss and the shallow stop concave are used, just align the first adjustment anvil and the second adjustment anvil with the outer diameter of the shallow stop boss, or put the adjustable anvil into the shallow stop recess. It can be used in the table, and then the diameter of the shallow stop boss and the shallow stop concave platform can be measured by comparing the apparent difference with the standard calibration gauge head, which not only avoids the waiting for the temperature conditions of the workpiece, but also eliminates the need for The high cost of using a CMM can quickly and accurately measure the size of the shallow spigot concave-convex table to ensure the dimensional accuracy of subsequent assembly.

Detailed ways

Below in conjunction with the accompanying drawings, the present utility model will be further described through embodiments.

As shown in FIGS. 1 and 2 , the measuring tool of the spigot concave and convex platform of the present invention includes a spigot boss measuring piece 1 and a spigot concave platform measuring piece 2 , wherein the spigot boss measuring piece 1 includes a convex platform ruler Specifically, the boss ruler frame 11 is in the shape of a semi-circle, and the two ends of the boss ruler frame 11 are arranged opposite to each other, and the two ends of the boss ruler frame 11 are respectively provided with straight rod-shaped first adjustment anvils 12 and the second adjusting anvil 13, in addition, a standard calibration gauge head 3 is installed on one end of the boss ruler frame 11, wherein, the zero position value of the standard calibration gauge head 3 is the pre-measured value of the spigot boss after processing. size.

The end-stop concave platform measuring member 2 includes a straight-bar-shaped concave platform ruler frame 21, one end of the concave platform ruler frame 21 is provided with a straight rod-shaped adjustable measuring anvil 25, and the other end of the concave platform ruler frame 21 is provided with a standard The calibration gauge head 3, wherein the zero value of the standard calibration gauge head 3 is the pre-measured size of the spigot concave platform after processing. Specifically, the concave scale frame 21 is connected with the adjustable anvil 25 through the thread 24 , and a locking nut 22 and an adjusting nut 23 are installed at the position of the thread 24 .

When it is necessary to measure the shallow stop boss, the measuring person holds the boss ruler frame 11, and places the first adjustment anvil 12 and the second adjustment anvil 13 on both sides of the shallow stop boss and their diameters are aligned. Then read out the digital difference value on the standard calibration gauge head 3. If there is no difference value, it means that the size of the measured shallow stop boss is up to standard, and if there is a difference value, it means that the dimensional accuracy is unqualified.
