Description

Detection measuring tool for cylindrical rotating shell

Technical Field

The utility model belongs to metalwork detection area especially relates to a detection measuring tool of rotatory shell of drum type.

Background

Fig. 1 and 2 are schematic structural views of a rotary casing of a conventional KUKA, one end of the casing body is cylindrical, a stepped structure is formed on an inner wall of the cylindrical body, and the stepped structure includes a first annular opening 100 having a larger inner diameter and a second annular opening 200 having a smaller inner diameter, and twenty uniformly distributed wire thread inserts 300 need to be assembled on the annular step.

Need guarantee that the installation of steel wire swivel nut total number does not have the leave-over at the in-process of steel wire swivel nut assembly, and the tip of steel wire swivel nut flushes with the step upper surface, does not have the arch. However, in actual production, assembly and detection are performed manually, the daily output is large, and continuous operation of operators is easy to cause fatigue, so that the condition that the wire thread insert is not installed or the tail end of the wire thread insert is cut off badly is caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is lower to look the efficiency of examining among the overcome prior art, and the higher defect of defective percentage provides a detection measuring tool of rotatory shell of drum type.

The utility model discloses a following technical scheme solves above-mentioned technical problem:

the utility model provides a detection measuring tool of rotatory shell of drum type, wherein the inner wall of waiting to detect the rotatory shell of drum type has that first annular is uncovered and the internal diameter is less than the uncovered second annular of first annular is uncovered, first annular uncovered with the uncovered formation annular step of second annular, be equipped with the swivel nut on the annular step, its characterized in that, the detection measuring tool of the rotatory shell of drum type include with the gauge body of the uncovered adaptation of first annular, be equipped with on the gauge body with the detection pinhole that the swivel nut position corresponds, be equipped with mobilizable detection pin in the detection pinhole.

Preferably, a positioning block matched with the second annular opening is arranged on the lower surface of the gauge body.

Preferably, the gauge body and the positioning block are both phenolic laminated cloth plates.

Preferably, a limit groove is formed in the side surface of the detection pin, the extending direction of the limit groove is parallel to the central axis of the detection pin, and a round pin is arranged on the side surface of the gauge body, penetrates through the side wall of the detection pin hole, and extends into the corresponding limit groove of the detection pin.

Preferably, the detection pin and the round pin are both made of nylon.

Preferably, the upper surface of the gauge body is provided with a handle.

The utility model has the advantages that: the utility model discloses a measuring tool of rotatory shell of drum type simple structure, convenient operation can the installation situation of swivel nut on the short-term test drum type work piece, reduce the reliance to the naked eye, have reduced intensity of labour, have improved detection efficiency and yields.

Detailed Description

The present invention will be more clearly and completely described with reference to the following preferred embodiments and the accompanying drawings.

As shown in fig. 3, the detection gauge of the cylindrical rotary casing in the present embodiment is used to detect the cylindrical rotary casing in fig. 1 and 2. The detection measuring tool comprises a measuring tool body 1 matched with the inner diameter of a first annular opening 100, wherein the measuring tool body 1 is provided with detection pin holes 2, the number and the distribution of the detection pin holes 2 correspond to the threaded sleeves 300, and movable detection pins 3 are arranged in the detection pin holes 2. A positioning block 4 matched with the inner diameter of the second annular opening 200 is arranged on the lower surface of the gauge body 1. In this embodiment, the gauge body 1 and the positioning block 4 are both phenolic laminated cloth plates.

In order to prevent the detection pin from falling off the detection pin hole accidentally in the detection process, a limit groove 31 is arranged on the side surface of the detection pin 3, the extending direction of the limit groove 31 is parallel to the central axis of the detection pin 3, a round pin 11 is arranged on the side surface of the gauge body 1, the round pin 11 penetrates through the side wall of the corresponding detection pin hole 2 and extends into the limit groove 31 on the corresponding detection pin 3, and therefore the limit of the detection pin in the detection pin hole in the up-and-down movement is limited. In this example, the detecting pin 3 and the round pin 11 are made of nylon. For the convenience of measurement, a handle 12 is further provided on the upper surface of the gauge body 1.

During detection, the gauge body is placed on the annular step, the detection pin corresponds to the threaded sleeve on the rotary shell in position, and if the threaded sleeve is assembled to meet the requirements, the detection pin is located at the same height. If the thread insert is omitted or the end part of the thread insert extends out of the upper surface of the annular step, the corresponding detection pin is correspondingly lower than or higher than the surrounding detection pins, so that the purpose of quick and effective detection is achieved.

Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
