Technical Field

[0002] The inner diameter measuring device at both ends of steel pipe fittings is a specialized testing equipment used to detect the inner diameter parameters of steel pipe fittings. With the promotion and deepening of automation, the inner diameter dimensions of products need to be fed back as soon as possible during actual processing to avoid batch defects. However, the existing conventional methods of inner diameter measurement include caliper measurement and inner diameter gauge measurement, which cannot achieve automated application, thus reducing the measurement efficiency of steel pipe fittings. Therefore, there is an urgent need for a steel pipe fitting inner diameter measuring mechanism to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5One embodiment of this utility model provides a steel pipe fitting inner diameter measuring mechanism, including a pneumatic base 5 for guidance, a linear slide rail 1 fixedly installed at the center of the upper end surface of the pneumatic base 5, and a positioning slide 4 slidably engaged with the linear slide rail 1 outside the pneumatic base 5.

[0022] Guide device 2 is fixedly installed on the upper end face of the positioning slide 4. Guide device 2 is used for guidance and detection.

[0023] The detection device 3 is fixedly installed at the center of the front end face of the guide device 2. The detection device 3 is used to detect the radial displacement of the steel pipe fitting.

[0024] The guide device 2 includes a support bracket 23, a telescopic cylinder 21 is fixedly installed at the center of the side end face of the support bracket 23, a guide push rod 22 is installed at the output end of the telescopic cylinder 21, and a support guide shaft 24 is installed at the end of the guide push rod 22.

[0025] The detection device 3 includes a support chuck 34, a limiting groove 33 is symmetrically opened on the side end face of the support chuck 34, a displacement sensing probe 31 is provided on the inner end face of the limiting groove 33, and a detection groove 32 is opened at the center of the inner end face of the support chuck 34.

[0026] Two sets of displacement sensing probes 31 extend into the interior of the support chuck 34. The support chuck 34 is then fixedly mounted on the outside of the support guide shaft 24 via the detection groove 32. The displacement sensing probes 31 are used to detect the radial displacement of the outer wall of the steel pipe fitting, thereby improving the efficiency of subsequent detection.

[0027] The front end face of the support bracket 23 is provided with a guide groove opposite to the support guide shaft 24. The guide groove is coaxial with the guide push rod 22 and the support guide shaft 24. The guide groove can facilitate the positioning and guidance of the steel pipe fitting, and improve the accuracy of subsequent inspection.

[0028] The telescopic cylinder 21 drives the support guide shaft 24 to telescopically move through the guide push rod 22, which facilitates the subsequent rapid and stable guiding and inspection of steel pipe fittings, and improves the accuracy and stability of steel pipe fitting inspection.

[0029] Working principle: Before use, the operator can position the steel pipe clamp between the two sets of equipment. After the clamp positions the steel pipe to be inspected between the two sets of equipment, the two sets of opposing telescopic cylinders 21 and guide push rods 22 can push the detection device 3 towards both ends of the steel pipe through the support guide shaft 24. At this time, the probe outside the displacement sensing probe 31 can extend into the inner wall of the steel pipe and contact the inner wall of the steel pipe. When the inner diameter of the steel pipe changes, the displacement sensing probe 31 will generate radial displacement. This displacement is transmitted to the displacement sensor through the internal transmission structure of the equipment. The displacement sensor converts the mechanical displacement into an electrical signal and transmits it to the position sensor. The position sensor processes the signal and converts it into the inner diameter data of the steel pipe, thereby completing the detection of the inner diameter of one end of the steel pipe. At the same time, since the two sets of equipment simultaneously detect both ends of the steel pipe in the middle, the detection efficiency can be effectively improved.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
