Description

Technical Field

[0001] This utility model relates to the field of testing mold technology, and more specifically, to a core tube testing mold. Background Technology

[0002] Core tubes are made from ordinary straight tubes through processes such as bending and welding. When core tubes are installed in relatively precise equipment, the dimensional accuracy requirements of the core tubes are high. Since core tubes have bending and welding parts, the main way to detect the dimensional error of the formed core tubes is still by manual measurement. However, due to the large production volume, measuring each one is not only inefficient but also inaccurate. Therefore, there is an urgent need for a mold for detecting the dimensional accuracy of core tubes. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a core tube testing mold, which aims to improve the existing technical problems of low efficiency and inaccuracy in core tube measurement.

[0004] This utility model is implemented as follows: a core tube testing mold includes a base plate, on which several tube body support plates and head support plates are provided. The upper surface of the tube body support plate is provided with a tube body positioning groove, and the side of the head support plate is provided with a bent head positioning groove.

[0005] Furthermore, the tube support plate includes a first support plate, a second support plate, and a third support plate. The first support plate has a first positioning groove, the second support plate has a second positioning groove, and the third support plate has a third positioning groove.

[0006] Furthermore, the first positioning groove is a horizontal semi-circular groove, the second positioning groove is inclined toward one end of the third support plate, and the third positioning groove is an arc-shaped groove.

[0007] Furthermore, the head support plate has a length tolerance groove at the end of the head positioning groove.

[0008] Furthermore, the head support plate has an expansion tolerance groove at the bend of the head positioning groove.

[0009] Furthermore, the base plate has a fixing groove, into which the tube body support plate and the head support plate are inserted.

[0010] The beneficial effects of this utility model are: This utility model discloses a core tube testing mold with a simple and ingenious design. It includes a base plate, on which several tube body support plates and head support plates are arranged. The upper surface of the tube body support plates has a tube body positioning groove, and the side of the head support plates has a bent head positioning groove. In use, the tube body of the core tube is placed in the tube body positioning groove, and the bent head of the core tube is placed in the head positioning groove. If both the tube body and head can fit into the respective grooves, the core tube size is acceptable; otherwise, it is unacceptable. This mold enables rapid testing of the tube body and head of the core tube, with high measurement efficiency and accuracy. Attached Figure Description

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.

[0017] Please refer to Figure 1 The core tube 20 includes a tube body 201 and a head 202. During measurement, both must be placed in the testing mold simultaneously for the dimensions to be considered acceptable.

[0018] Please refer to Figure 2-4This utility model provides a core tube 20 testing mold, including a base plate 10. Several tube body 201 support plates and head support plates 104 are arranged on the base plate 10. Specifically, the base plate 10 has fixing grooves, and the tube body 201 support plates and head support plates 104 are inserted into the fixing grooves to realize the installation of the tube body 201 support plates and head support plates 104 on the base plate 10. The base plate 10 has different numbers of fixing grooves according to different core tube 20 sizes, so as to install tube body 201 support plates of different heights and different numbers, thereby improving practicality.

[0019] Please refer to Figure 2-4 The upper surface of the tube body 201 support plate has a tube body 201 positioning groove. Specifically, in this embodiment, the tube body 201 support plate includes a first support plate 101, a second support plate 102 and a third support plate 103. The first support plate 101 has a first positioning groove 1011, the second support plate 102 has a second positioning groove 1021, and the third support plate 103 has a third positioning groove 1031. According to the length of the core tube 20, the tube body 201 of the core tube 20 is placed in the first positioning groove 1011, the second positioning groove 1021 and the third positioning groove 1031 respectively. The first positioning groove 1011 is a horizontal semi-circular groove, the second positioning groove 1021 is inclined towards one end of the third support plate 103, and the third positioning groove 1031 is an arc-shaped groove.
