Description

Technical Field

[0001] The present invention relates to the technical field of pipe fitting inspection tools, and in particular to a tool for detecting the outline of a pipe fitting. Background Art

[0002] A pipe gauge is a special tool or device for measuring and evaluating pipe fittings. It can be used to measure the outer contour of pipe fittings, such as pipes, pipe joints, pipe caps and other pipe fittings with specific shapes.

[0003] In the existing technology, after a series of processing, pipe fittings need to enter the inspection link to inspect the outer contour of the pipe fittings. The pipe fittings are inspected to determine whether they are qualified products. The measurement of the pipe fittings is obtained directly by tools. The shape of the existing pipe fittings is shown in Figure 2. Figure 6 , including two side rods 200 and a connecting rod 100 arranged between the two side rods 200, each side rod 200 includes a straight rod segment 2001, a vertical rod segment 2002 and an oblique rod segment 2003, the oblique rod segment 2003 is connected to the connecting rod 100, the vertical rod segment 2002 is connected between the oblique rod segment 2003 and the straight rod segment 2001, and the straight rod segment 2001 is connected to the end of the vertical rod segment 2002 away from the oblique rod segment 2003. It is difficult to measure the angles between different rod segments of the side rod 200, and the detailed contour shape of the pipe fitting obtained by feedback cannot be guaranteed.

[0004] The above-mentioned detection of the outer contour of the pipe fittings requires comparing the actual measured dimensions of the pipe fittings with the specified standard dimensions to determine whether the pipe fittings are qualified. The existing pipe fitting size accuracy detection is difficult and the measurement takes a long time, resulting in poor efficiency and needs to be improved. Summary of the Invention

[0005] In order to improve the problem of poor efficiency caused by the long time spent on measuring pipe dimensions, this technical solution provides a pipe contour detection tool.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A tool for detecting the contour of a pipe fitting includes a mounting frame, the mounting frame is provided with a support assembly, the support assembly includes support block one and support block two, support block one and support block two are used to cooperate with each other for the pipe fitting to abut against, the mounting frame is provided with a mounting seat, the mounting seat is provided with a measuring part, the measuring part has a detection surface, and the detection surface is used for the inclined rod section to fit when the pipe fitting is placed on support block one and support block two.

[0008] Through the above technical solution, when the pipe contour detection tool is in normal use, a pipe with a specific contour is placed on the mounting frame, and the pipe is supported by the side rod portion resting on the support block one. When the pipe is pushed to move, the straight rod section of the side rod will gradually rest on the support block two, so as to further increase the stable support. The pipe moves until the inclined rod section contacts the measuring part, and the plane of the detection surface matches the contour contact surface of the inclined rod section. By detecting whether the inclined rod section can fit on the detection surface of the measuring part, it is judged whether the angle dimension between the inclined rod section and the straight rod section meets the requirements. When the inclined rod section can completely fit on the detection surface, it means that the angle dimension meets the requirements; when there is a gap between the inclined rod section and the detection surface, it means that the angle dimension does not meet the requirements, so as to quickly complete the positioning and measurement of the pipe fitting, reduce the measurement time, and improve the measurement efficiency of the pipe fitting.

[0009] Preferably, there are two support assemblies, and the two support assemblies are arranged relatively along the side rods on both sides of the pipe fitting. The mounting frame is located between the support assemblies on both sides. The upper end surfaces of the support block 1 and the support block 2 are both provided with a conduit groove, and the width of the conduit groove is adapted to the pipe diameter of the straight rod section. The conduit groove is used for the straight rod section to be embedded and positioned.

[0010] Through the above technical solution, two support assemblies are provided and are arranged relative to the positions of the side rods on both sides of the pipe fitting, which are suitable for the side rods on both sides to lean against and stably support the pipe fitting. The positions of the two support assemblies are relatively fixed. By detecting whether the side rods on both sides of the pipe fitting can lean against the support assemblies on both sides one by one, it is judged whether the distance between the two side rods meets the requirements. Based on the adaptation of the catheter groove width to the pipe diameter of the straight rod section, it is ensured that the straight rod section can be embedded in the corresponding catheter groove when in contact with support block one and support block two, and whether it contacts the inner walls on both sides of the catheter groove, so as to judge whether the pipe diameter of the straight rod section meets the requirements, thereby improving accuracy and further improving measurement efficiency.

[0011] Preferably, the mounting bracket is provided with a positioning portion, and when the detection surface is in contact with the oblique rod segment, the positioning portion is used to abut against the vertical rod segment.

[0012] Through the above technical solution, when the detection surface is in contact with the oblique rod section, the vertical rod section of the side rod will move to a position where it can abut against the positioning part. By detecting whether the vertical rod section can be in contact with the positioning part, it is possible to judge whether the size of the vertical rod section relative to the straight rod section and the oblique rod section meets the requirements, which is convenient for evaluating the external contour of the vertical rod section and further improving the measurement efficiency.

[0013] Preferably, an abutting portion is provided at the upper end of the mounting seat, and when the upper end surface of the abutting portion abuts against the connecting rod, the bottom of the conduit groove is used for abutment of the straight rod section.

[0014] Through the above technical solution, when the connecting rod abuts against the upper end surface of the abutting portion, based on the connection between the side rods on both sides of the connecting rod, the side rods on both sides are embedded in the catheter groove. By detecting whether the straight rod section can fit into the bottom of the catheter groove, it is determined whether the height distance between the connecting rod and the straight rod section meets the requirements, thereby further improving the measurement efficiency.

[0015] Preferably, the abutting portion has a limiting portion, which is located at one end of the abutting portion away from the mounting seat. When the side wall of the limiting portion abuts against the connecting rod, the end surface of the support block 2 away from the support block 1 is used to be flush with the straight rod section.

[0016] Through the above technical solution, the abutting portion has a limiting portion. When the pipe fitting moves along the abutting portion, by detecting whether the connecting rod can fit with the side wall of the limiting portion, it is judged whether the distance between the connecting rod and the vertical rod section meets the requirements, and by detecting whether the straight rod section is flush with the end face of the side of the support block 2 away from the support block 1, it is judged whether the distance between the straight rod section and the vertical rod section meets the requirements, which is convenient for evaluating the external contour between the straight rod section and the connecting rod, and further improving the measurement efficiency.

[0017] Preferably, the measuring part is provided with two measuring grooves, which are symmetrically arranged relative to the two ends of the measuring part, the groove width of the measuring groove is adapted to the tube diameter of the inclined rod section, the detection surface is arranged at the bottom of the measuring groove, and the measuring part is inclined to make the detection surface face the inclined rod section.

[0018] Through the above technical solution, the width of the measuring groove is adapted to the pipe diameter of the oblique rod section. When the oblique rod section contacts the measuring part, it can be embedded in the corresponding measuring groove and whether it fits with the inner walls on both sides of the measuring groove is used to judge whether the pipe diameter of the oblique rod section meets the requirements, thereby improving accuracy. The detection surface is built into the bottom of the measuring groove, and the measuring part adopts an inclined setting so that the inclined surface faces the oblique rod section, which facilitates the accurate embedding of the oblique rod section, effectively reduces the collision with the pipe fittings during the measurement process, and improves protection.

[0019] Preferably, the mounting frame is provided with two embedding holes 1, and the positions of the two embedding holes 1 correspond to two support blocks 1 set for embedding and positioning. The mounting frame is provided with two embedding holes 2, and the positions of the two embedding holes 2 correspond to two support blocks 2 set for embedding and positioning.

[0020] Through the above technical solution, two embedding holes 1 and two embedding holes 2 are reserved on the mounting frame, the positions of the two embedding holes 1 and the two embedding holes 2 are relatively fixed, the lower ends of the two support blocks are inserted into the two embedding holes 1 one by one to be fixed, and the lower ends of the two support blocks 2 are inserted into the two embedding holes 2 one by one to be fixed, so that the installation positions of the support blocks 1 and 2 are more accurate, thereby improving the accuracy.

[0021] Preferably, the mounting frame is provided with a socket for the lower end of the mounting seat to be embedded therein.

[0022] Through the above technical solution, a socket is reserved on the mounting frame, the position of the socket is relatively fixed, and the lower end of the mounting base is aligned with the socket and inserted into it for fixation, so that the installation position of the mounting base is more accurate, thereby improving accuracy.

[0023] Preferably, the mounting seat is provided with a first mounting groove and a second mounting groove, and the positioning portion and the measuring portion are respectively embedded in the first mounting groove and the second mounting groove in a one-to-one correspondence for fixation.

[0024] Through the above technical solution, the size of mounting groove one is adapted to the positioning part, and the size of mounting groove two is adapted to the measuring part. The positioning part and the measuring part are respectively embedded in mounting groove one and mounting groove two in a one-to-one correspondence, and are fixed to the mounting seat by welding in the corresponding mounting grooves.

[0025] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0026] 1. This technical solution provides a support assembly and a mounting base on the mounting frame. The mounting base is provided with a measuring part having a detection surface. The pipe fitting is placed on the first support block and the second support block. When the inclined rod section fits the detection surface, the angle dimension meets the requirements. When there is a gap between the inclined rod section and the detection surface, the angle dimension does not meet the requirements. This reduces measurement time and improves the measurement efficiency of the pipe fitting.

[0027] 2. This technical solution provides a conduit groove on the upper end surface of both support block 1 and support block 2, and two measuring grooves on the measuring part. The straight rod section and the oblique rod section are respectively inserted into the conduit groove and the measuring groove to determine whether the pipe diameter meets the requirements;

In this example, the pipe includes a connecting rod 100 and two side rods 200, and the connecting rod 100 is connected between the two side rods 200. The two support assemblies 2 are spaced apart, and the spacing direction corresponds to the position of the side rods 200 on both sides of the pipe symmetrically arranged in the horizontal direction. Each support assembly 2 includes a support block 1 21 and a support block 2 22. The support block 1 21 And the support block 2 22 is distributed relatively front and back in the horizontal direction, and the distribution direction is perpendicular to the distribution direction of the two support components 2. The support block 1 21 and the corresponding support block 2 22 are used to provide support for the pipe fittings; when the pipe fittings are placed on the mounting frame 1, when the side rods 200 on both sides are in one-to-one correspondence with the support blocks 1 21 and support blocks 2 22 on both sides, the distance size between the side rods 200 on both sides meets the requirements. When the side rods 200 on both sides deviate from the support blocks 1 21 and support blocks 2 22 on both sides, the distance size between the side rods 200 on both sides does not meet the requirements.

[0039] The upper end surfaces of the support block 1 21 and the support block 2 22 are provided with a conduit groove 6, and the length directions of the two conduit grooves 6 are relatively conductive. In this example, each side rod 200 includes an oblique rod section 2003 arranged on the connecting rod 100, a vertical rod section 2002 arranged on the oblique rod section 2003, and a straight rod section 2001 arranged on the vertical rod section 2002. The straight rod sections 2001 are embedded in the conduit grooves 6 one by one. When the diameter of the straight rod section 2001 is adapted to the groove width of the conduit groove 6, the straight rod section 2001 fits with the two side walls of the conduit groove 6, and the diameter size of the straight rod section 2001 meets the requirements. When the diameter of the straight rod section 2001 cannot fit with the two side walls of the conduit groove 6 at the same time, the diameter of the straight rod section 2001 is smaller than the required size. When the straight rod section 2001 cannot be embedded in the conduit groove 6, the diameter of the straight rod section 2001 is larger than the required size.

[0040] The mounting frame 1 is provided with a mounting seat 3, which is located between the support components 2 on both sides, and the mounting seat 3 is located near the support block 1 21.

The position of the measuring part 4 is adapted to the position of the inclined rod segment 2003 for the inclined rod segment 2003 to abut against. The measuring part 4 is inclined corresponding to the inclination direction of the inclined rod segment 2003.

[0041] See also Figure 2 and Figure 4 The mounting seat 3 is also provided with a second mounting groove 15. The position of the second mounting groove 15 corresponds to the measuring part 4 for the measuring part 4 to be embedded and fixed. The measuring part 4 is provided with two measuring grooves 10. The two measuring grooves 10 are respectively located at the two ends of the measuring part 4. The two oblique rod sections 2003 are embedded in the two measuring grooves 10 in a one-to-one correspondence. When the diameter of the oblique rod section 2003 is adapted to the width of the measuring groove 10, the oblique rod section 2003 fits with the two side walls of the measuring groove 10, and the diameter size of the oblique rod section 2003 meets the requirements. When the diameter of the oblique rod section 2003 cannot fit with the two side walls of the measuring groove 10 at the same time, the diameter of the oblique rod section 2003 is smaller than the required size. When the oblique rod section 2003 cannot be embedded in the measuring groove 10, the diameter of the oblique rod section 2003 is larger than the required size.

[0042] The measuring part 4 has two detection surfaces 5, and the two detection surfaces 5 are arranged one-to-one at the bottom of the two measuring grooves 10. When the side rods 200 on both sides are in one-to-one contact with the support blocks 1 21 and 22 on both sides, and the two oblique rod sections 2003 are in contact with the detection surfaces 5, when the two oblique rod sections 2003 are in contact with the two detection surfaces 5, the angle dimension between the oblique rod section 2003 and the straight rod section 2001 meets the requirements. When there is a gap between the two oblique rod sections 2003 and the two detection surfaces 5 and they cannot be in contact, it does not meet the requirements.

[0043] See also Figure 3 and Figure 5 The mounting seat 3 is provided with a positioning portion 7, which is located on the side of the mounting seat 3 away from the measuring portion 4 and is arranged close to the mounting frame 1 relative to the position of the measuring portion 4. The positioning portion 7 is adapted to the position of the vertical rod segment 2002 for the vertical rod segment 2002 to abut against. The mounting seat 3 is also provided with a mounting groove 14, and the position of the mounting groove 14 corresponds to the positioning portion 7 for the positioning portion 7 to be embedded and fixed; when the detection surface 5 is fitted with the oblique rod segment 2003, and the vertical rod segment 2002 abuts against the positioning portion 7, when the positioning portion 7 is fitted with the vertical rod segment 2002, the outer contour of the vertical rod segment 2002 relative to the straight rod segment 2001 and the oblique rod segment 2003 meets the requirements. When there is a gap between the positioning portion 7 and the vertical rod segment 2002 and they cannot be fitted, it does not meet the requirements.

[0044] The mounting seat 3 is provided with a rest portion 8, which is located at the upper end of the mounting seat 3. The rest portion 8 extends in a direction away from the positioning portion 7, and the connecting rod 100 rests on the upper end surface of the rest portion 8. When the straight rod section 2001 is in contact with the bottom of the catheter groove 6, the distance between the straight rod section 2001 and the connecting rod 100 meets the requirements.

[0045] The leaning portion has a limiting portion 9, which is located at the end of the leaning portion 8 away from the mounting seat 3, and the side wall of the limiting portion 9 leans against the connecting rod 100. When the end face of the side of the support block 22 away from the support block 1 21 is flush with the straight rod section 2001, the outer contour of the straight rod section 2001 relative to the connecting rod 100 meets the requirements. When the end face of the side of the support block 22 away from the support block 1 21 cannot be flush with the straight rod section 2001, it does not meet the requirements.

[0046] The mounting frame 1 is provided with a socket 13 , which is adapted to the mounting seat 3 . The mounting seat 3 is inserted into the socket 13 , and the socket 13 is used for the lower end of the mounting seat 3 to be embedded.

The mounting frame 1 also has two embedding holes 12 running through it, which are adapted to the two support blocks 22, and the positions of the two embedding holes 12 correspond one-to-one with the two support blocks 22. The two support blocks 22 are embedded in the two embedding holes 12 and fixed in position.

[0048] The specific working process of this program is as follows:

[0049] The present technical solution is to place the pipe fitting on the mounting frame 1, with the connecting rod 100 resting on the upper end face of the resting portion 8, and the side rods 200 on both sides resting on the two support assemblies 2 in a one-to-one correspondence, and the straight rod section 2001 is embedded in the conduit groove 6. When the pipe fitting moves to the point where the connecting rod 100 is in contact with the side wall of the limiting portion 9, the straight rod section 2001 and the support block 2 22 are away from the end face of one side of the support block 1 21, and the straight rod section 2001 is in contact with the bottom of the conduit groove 6. At this time, the oblique rod section 2003 is embedded in the measuring groove 10 and in contact with the detection surface 5. At the same time, the positioning portion 7 is in contact with the vertical rod section 2002. When the above components are all in contact with each other, it indicates that the overall outline size meets the requirements. When there is a gap at the resting position, it indicates that it does not meet the requirements, thereby achieving rapid completion of the positioning and measurement of the pipe fitting, reducing the measurement time, and improving the measurement efficiency of the pipe fitting.
