The positioning mechanism is used to support and position the part to be measured. Together with the dimension measuring machine, it enables the rapid and accurate identification of the part and the efficient completion of the dimension measurement operation.

[0003] In the existing technology, the dimensional measurement system is equipped with positioning mechanisms that are designed for the same type of parts and have a small size range. This cannot meet the load-bearing positioning requirements of a variety of parts. Different positioning mechanisms need to be changed when measuring different parts, which is cumbersome and results in low overall measurement efficiency.

[0004] Therefore, there is an urgent need for a part size measuring device to solve the above problems. Utility Model Content

Both the positioning mechanism and the size measuring mechanism are mounted on the support frame and are movable relative to the support frame. The size measuring mechanism can measure parts on the positioning mechanism. The positioning mechanism includes a main disc with a central positioning platform on it. The central positioning platform is cylindrical, and its axis coincides with the axis of the main disc. The main disc also has multiple arc-shaped positioning elements arranged circumferentially around the central positioning platform, with the centers of the arc-shaped positioning elements located on the axis of the main disc.

The plurality of first fixing holes are provided one-to-one with the plurality of second fixing holes. Any first fixing member can be inserted and fixed in any of the first fixing holes and the corresponding second fixing holes.

[0010] Furthermore, the second fixing hole is a countersunk hole.

[0011] Furthermore, three arc-shaped positioning elements are provided, and the sum of the central angles of the three arc-shaped positioning elements is greater than 270°.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0024] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0027] This embodiment provides a part size measuring device that can locate a variety of different parts, meeting the requirement that part size measuring devices can locate multiple parts, and is convenient to use, thus improving efficiency.

[0028] like Figures 1-2 As shown, in this embodiment, the part size measuring device includes a support frame 1, a positioning mechanism 2, and a size measuring mechanism. Both the positioning mechanism 2 and the size measuring mechanism are mounted on the support frame 1 and can move relative to the support frame 1. The size measuring mechanism can measure the parts on the positioning mechanism 2. The positioning mechanism 2 includes a main disc 21 with a central positioning platform 22. The central positioning platform 22 is cylindrical, and its axis coincides with the axis of the main disc 21. Multiple arc-shaped positioning elements 23 are also provided on the main disc 21, arranged circumferentially around the central positioning platform 22, with their centers located on the axis of the main disc 21. Through the shape of the central positioning platform 22, the shapes of the multiple arc-shaped positioning elements 23, and the space defined between the central positioning platform 22 and the multiple arc-shaped positioning elements 23, various different parts can be positioned, meeting the requirement of the part size measuring device to position multiple parts. This method is convenient to use and improves efficiency.

[0029] Furthermore, it can be conceived that by utilizing the cylindrical shape of the central positioning platform 22, the structure of the multiple arc-shaped positioning elements 23, and the different spaces defined between the central positioning platform 22 and the multiple arc-shaped positioning elements 23, it is possible to carry and position circular or ring-shaped parts of different types and sizes.

[0030] It should be noted that, in this embodiment, the arc-shaped positioning element 23 may be part of a circular ring.

[0031] Furthermore, multiple arc-shaped positioning elements 23 are detachably mounted on the main body disk 21. It is understood that by setting multiple arc-shaped positioning elements 23 to be detachably mounted on the main body disk 21, the installation and removal of the arc-shaped positioning elements 23 are facilitated, and different arc-shaped positioning elements 23 can be replaced, thereby improving the applicability of the positioning mechanism 2.

[0032] Furthermore, the positioning mechanism 2 also includes multiple first fixing components. The main disc 21 has multiple positioning areas, each with a first fixing hole. Each of the multiple arc-shaped positioning components 23 has a second fixing hole 231. The multiple positioning areas correspond one-to-one with the multiple arc-shaped positioning components 23, and the multiple first fixing holes correspond one-to-one with the multiple second fixing holes 231. Any first fixing component can be inserted into and fixed in any first fixing hole and its corresponding second fixing hole 231. It can be understood that the one-to-one correspondence between the multiple positioning areas and the multiple arc-shaped positioning components 23 facilitates the placement of the arc-shaped positioning components 23 in their respective positioning areas during the installation of the positioning mechanism 2. Furthermore, each first fixing component can be inserted into and fixed in any first fixing hole and its corresponding second fixing hole 231; that is, all the first fixing components are identical and applicable to all first fixing holes and multiple second fixing holes 231, making it convenient for operators to install and fix the arc-shaped positioning components 23.

[0033] Of course, the number of first fixing holes in each positioning area and the number of second fixing holes 231 on each arc-shaped positioning component 23 can be determined according to actual usage requirements, and can be multiple, such as 2, 3, 4, etc.

[0034] In this embodiment, the second fixing hole 231 is a countersunk hole. It is understood that by setting the second fixing hole 231 as a countersunk hole, the end of the first fixing member can be located below the end face of the arc-shaped positioning member 23, avoiding collisions between the first fixing member and the part, and preventing damage to the surface quality of the part. In this embodiment, the first fixing hole can be a threaded hole, the second fixing hole 231 can be a countersunk threaded hole, and the first fixing member can be a bolt or screw.

[0035] In this embodiment, three arc-shaped positioning elements 23 are provided, and the sum of the central angles of the three arc-shaped positioning elements 23 is greater than 270°. It can be understood that when the sum of the central angles of the three arc-shaped positioning elements 23 is greater than 270°, the three arc-shaped positioning elements 23 occupy a large portion of the ring-shaped component, functioning similarly to a complete ring-shaped component. Furthermore, there are gaps between adjacent arc-shaped positioning elements 23, facilitating the placement of parts within the space formed by the three arc-shaped positioning elements 23 by the operator. The specific angle values ​​of the central angles of the arc-shaped positioning elements 23 can be determined according to actual usage requirements.

[0036] Of course, in other embodiments, the sum of the central angles of the three arc-shaped positioning elements 23 is 360°, that is, the three arc-shaped positioning elements 23 can form a ring, and the central angle of each arc-shaped positioning element 23 is 120°, or the central angles of the three arc-shaped positioning elements 23 can be different.

[0037] In this embodiment, the positioning mechanism 2 further includes a plurality of first fixing members. The main body disk 21 is provided with a plurality of positioning areas, each of which is provided with a first fixing hole. The plurality of arc-shaped positioning members 23 are provided with a second fixing hole 231.

[0038] In this embodiment, the part size measuring device further includes a sliding mechanism 3 and multiple second fixing members. The sliding mechanism 3 is mounted on the support frame 1 and includes a sliding rail and a slider that are slidably fitted. The slider has multiple third fixing holes, and the main body disk 21 has multiple fourth fixing holes 211. The multiple third fixing holes and multiple fourth fixing holes 211 are arranged one-to-one and correspond one-to-one with the multiple second fixing members. It can be understood that by setting the sliding rail and slider that are slidably fitted, the movement of the positioning mechanism 2 relative to the support frame 1 is facilitated. The slider has multiple third fixing holes, and the main body disk 21 has multiple fourth fixing holes 211. The multiple third fixing holes and multiple fourth fixing holes 211 are arranged one-to-one and correspond one-to-one with the multiple second fixing members. The second fixing members can pass through and be fixed in the corresponding third fixing holes and fourth fixing holes 211, so as to install the main body disk 21 on the slider and improve the stability of the installation.

[0039] Furthermore, the end face of the arc-shaped positioning member 23 and the inner surface of the arc-shaped positioning member 23 are transitioned by an arc surface. It can be understood that the arc surface transition can reduce the collision intensity between the part and the arc-shaped positioning member 23, thus protecting the surface quality of the part.

[0040] For example, the diameter of the main disc 21 is 600 mm, which matches the measuring area of ​​the dimensional measuring mechanism.

[0041] In this embodiment, the diameter of the circle containing the inner side of the arc-shaped positioning element 23 is 390 mm, the diameter of the circle containing the outer side of the arc-shaped positioning element 23 is 450 mm, and the thickness of the arc-shaped positioning element 23 is 20 mm. That is, the outer diameter of the ring containing the three arc-shaped positioning elements 23 is 450 mm, and the inner diameter is 390 mm. In other words, in the radial direction of the arc-shaped positioning element 23, the diameters of the two arc surfaces of the arc-shaped positioning element 23 are 390 mm and 450 mm, respectively.

[0042] The center positioning stage 22 has a diameter of 50mm and a height of 5mm, and continues to position annular parts with an inner hole diameter of less than 90mm and greater than 50mm.

[0043] In this embodiment, the dimensional measuring mechanism has a vision recognition system capable of measuring the dimensions of the parts. The vision recognition system can be an existing vision recognition system that meets the actual usage requirements; this embodiment does not impose any specific limitations.

[0044] It can be understood that this embodiment uses a main disc 21 with a diameter of 600mm that matches the measurement area of ​​the dimensional measuring mechanism. Three arc-shaped positioning parts 23, each with a diameter of 390mm for the inner side and 450mm for the outer side, and a thickness of 20mm, are fixed on the main disc 21. Simultaneously, a central positioning platform 22 with a diameter of 50mm and a height of 5mm is set at the center of the main disc 21. This facilitates the adaptation and positioning of over twenty types of motor parts, such as bearing covers, end covers, and bearing seats, for traction motors of different high-speed train models (platforms) on the part dimensional measuring equipment. Examples include the end cover and labyrinth ring of the traction motor with the model code CRH1A, and the inner and outer sealing rings of the traction motor with the model code CR400AF. The positioning mechanism 2 is mounted on the sliding mechanism 3 of the part dimensional measuring equipment. After the part is positioned on the fixture, the sliding platform can drive the positioning mechanism 2 and the part into the measurement area. This allows the visual recognition system of the dimensional measuring mechanism to achieve rapid and accurate identification and efficient dimensional measurement of the part.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
