Description
Technical Field
The utility model relates to a measurement field specifically relates to an utensil is examined to short tang based on micrometer for the measurement of work piece.
Background
On some parts, the precision that needs is higher, generally measures by the micrometer, but because part structure problem, measuring tool can not directly measure, and the measuring head of micrometer has two, a long head, and a anvil measurement, and one side of long measuring head can directly contact with the tang excircle of measurationing, and one side of short measuring head is because the attached examination of measuring head is concrete and the terminal surface of tang to interfere, can not directly contact with the tang excircle, so can not measure with external micrometer direct measurement. At present, the detection of the parts is carried out by a three-coordinate measuring machine.
In some places, the three-coordinate measuring machine is few, the variety and the number of the detected parts are large, and the three-coordinate detecting process becomes a bottleneck process in production and influences the mass production of the parts.
SUMMERY OF THE UTILITY MODEL
An object of the present invention is to solve at least the above problems and/or disadvantages and to provide at least the advantages which will be described later.
Short tang examine utensil based on micrometer, can be used for accuracy, convenient, swiftly detect short tang size, and need not detect with the three-coordinate measuring machine, make the normal batch production of part production line ability, reduce and detect latency and check-out time to improve production efficiency.
To achieve these objects and other advantages in accordance with the purpose of the invention, a short spigot gauge based on a micrometer is provided;
structural description: the micrometer has two measuring heads, one is a fixed head and relatively short, and the other is a turnable head and relatively long. During measurement, the measuring anvil is relatively fixed relative to the workpiece, and the long head is moved to find the position with the largest diameter for measurement. The standard micrometer anvil is too short to measure the size of the spigot, so that a transition sleeve and an extension rod are added on the anvil, a cutting groove is formed in the transition sleeve, the transition sleeve and the micrometer anvil are hooped tightly through screw compression, an internal thread is processed in the transition sleeve and used for installing an external thread end of the extension rod, the extension rod is screwed tightly to enable one end face of the extension rod to be tightly connected with the end face of the micrometer anvil, the length of the extension rod has micron-level precision, the extension rod extends the length of the micrometer anvil, and interference between the micrometer anvil and the end face of a part is avoided.
The working principle is as follows:
during measurement, the transition sleeve and the micrometer anvil are hooped by screws, the extension rod is screwed into the transition sleeve, and the measurement can be performed after the gap is tightened and eliminated. After the extension rod is added, the measurement length is increased equivalently, and the value obtained by subtracting the length of the extension rod from the final measurement value of the micrometer is the size of the measured part.
The utility model has the advantages that:
(1) simple structure, application range is wide: the gauge is simple in structure and wide in application range, and can be popularized to solve similar problems.
(2) The connection is convenient, and the detection efficiency is improved.
(3) The universality is strong, and the sizes of different types of short rabbets can be measured.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Detailed Description
The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
The positioning fixture provided by the present invention will be further described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in figure 1, the utility model comprises a micrometer main body 1, wherein the micrometer main body 1 comprises a short-end measuring anvil 2, a long-end micrometer screw rod and an extension component, the extension component is arranged on the measuring anvil 2 of the micrometer main body 1,
wherein the extension assembly comprises: the extension rod 5 and the transition sleeve are used for connecting the extension rod 5 and the measuring anvil 2 of the micrometer main body 1.
As shown in fig. 2 and 3, optionally, the transition sleeve 4 of the extension assembly is sleeved on the anvil 2 of the micrometer body 1. And the transition sleeve 4 is provided with a screw 3 for fastening the transition sleeve 4 and the measuring anvil 2.
Since the precision requirement of the part to be measured is high, in order to ensure the measurement precision, the precision of the extension rod 5 needs to be ensured, and it can be understood that the extension rod 5 has micron-scale precision.
It can be understood that, in order to ensure that the extension rod 5 can be stably connected with the transition sleeve 4, an external thread is arranged at one end of the extension rod 5 connected with the measuring anvil 2, and an internal thread for connecting the extension rod 5 is arranged inside one end of the transition sleeve 4 connected with the extension rod 5.
In the embodiment of the present invention, as shown in fig. 1, the structure and the working principle are as follows:
structural description: the micrometer main body has two measuring heads, one is a fixed head measuring anvil and is relatively short, and the other is a long head micrometer screw and is relatively long. During measurement, the measuring anvil 2 is relatively fixed relative to the workpiece, and the long head is moved to find the position with the largest diameter for measurement. Because standard micrometer caliper survey anvil 2 is too short, can't measure the tang size, so increased a transition cover 4 and an extension rod 5 on survey anvil 2, it has the grooving to open on the transition cover 4, compress tightly through screw 3 with the transition cover 4 with micrometer main part 1 survey anvil 2 cramp, it has the internal thread to process in the transition cover 4, the external screw thread end for installing extension rod 5, screw up extension rod 5 and make its terminal surface link to each other with micrometer main part 1 survey anvil 2 terminal surface is tight, extension rod 5 length has micron order precision, extension rod 5 has prolonged the length of micrometer main part 1 survey anvil 2, avoided micrometer main part 1 survey anvil 2 position blade and part terminal surface interference.
The working principle is as follows: during measurement, the transition sleeve 4 and the measuring anvil 2 of the micrometer main body 1 are hooped by the screw 3, then the extension rod 5 is screwed into the transition sleeve 4, and measurement can be performed after the gap is tightened and eliminated. After the extension rod 5 is added, the measurement length is increased, and the value obtained by subtracting the length of the extension rod 5 from the final measurement value of the micrometer body 1 is the size of the measured part.
While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments. It can be applicable to various and be fit for the utility model discloses a field completely. Additional modifications will readily occur to those skilled in the art.
