Description

Technical Field

[0001] The present invention relates to the technical field of detection tooling, and particularly relates to a detection device for the spatial position degree of multiple holes, as well as a manufacturing and detection method thereof. Background Art

[0002] For products provided with multiple holes, especially for aerospace equipment products, generally high requirements are imposed on the quality and precision of the products. The existing methods for detecting the hole positions of products with multiple holes are as follows: one is to measure with tools such as calipers and compare with standard data to determine whether the hole positions meet the precision requirements. This detection method is applicable to products with single or two hole positions, but it is difficult to meet the high-precision requirements of multiple hole positions and is not applicable to mass production, directly resulting in low production efficiency. The other is to adopt the three-coordinate measurement method to detect the hole positions of products with multiple holes by using a three-coordinate measuring instrument. Although the detection efficiency can be improved, its cost is high, and the assembly and use performance of the products cannot be verified.

[0003] In order to solve the technical problem that the traditional hole position detection method cannot meet the high-precision requirements of products with multiple holes in mass production, and at the same time to achieve the purpose of cost reduction, a detection device different from the existing detection methods is provided. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a detection device with a simple structure and convenient operation in view of the problems in the background art. By using this detection device, the detection of products with multiple holes can be satisfied, and the assembly and use performance of the products can be verified in a timely manner. Not only can the detection efficiency be improved, but also the cost can be effectively reduced. At the same time, a manufacturing and detection method for this detection device is also provided, specifically a detection device for the spatial position degree of multiple holes and a manufacturing and detection method thereof.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A detection device for the spatial position degree of multiple holes includes a simulation fitting and a positioning assembly. The outer shape structure of the simulation fitting matches the outer shape structure of the workpiece product to be detected. A plurality of first detection components corresponding to the main hole positions of the workpiece product to be detected are provided on the top surface of the simulation fitting. A plurality of second detection components corresponding to the secondary hole positions of the workpiece product to be detected are provided on the side surface of the simulation fitting, and a positioning reference assembly corresponding to the second detection components is further provided on the top surface of the simulation fitting; A positioning assembly corresponding to the first detection components and the second detection components is further included. Through the cooperation of the positioning assembly and the corresponding detection components, a detachable connection between the positioning assembly and the simulation fitting is realized.

[0006] Furthermore, for a porous spatial position detection device according to the present invention, the simulation fitting is a cavity structure with a receiving cavity, the first detection component is a first detection hole, the second detection component is a second detection hole, and the positioning component is a pin. The positioning component is detachably connected to the simulation fitting by detachably inserting the pin into the corresponding first detection hole and second detection hole; the positioning reference component is a positioning groove, which coincides with the top surface center line of the simulation fitting and is arranged at a symmetric included angle with the second detection hole.

[0007] Furthermore, for a porous spatial position detection device according to the present invention, the simulation fitting is a cylindrical body with openings at both ends, and the cylindrical body matches the outer shape structure of the workpiece product to be detected. On the top surface of the cylindrical body, there are three first detection holes corresponding to the main hole positions of the workpiece product to be detected. The three first detection holes are evenly distributed in a ring on the top surface of the cylindrical body. One of the first detection holes is arranged along the horizontal center line of its top surface and coincides with the reference hole of the workpiece product to be detected; on the side surface of the cylindrical body, there are eight second detection holes corresponding to the secondary hole positions of the workpiece product to be detected. The eight second detection holes are divided into four groups, and the four groups of second detection holes are evenly distributed in a ring on the side surface of the cylindrical body; the positioning groove is arranged along the vertical center line of its top surface and is symmetrically distributed on both sides of the first detection hole arranged along the horizontal center line of its top surface. Among them, two groups of second detection holes are symmetrically arranged along the horizontal center line of its top surface, and the other two groups of second detection holes are symmetrically arranged along the vertical center line of its top surface. The two second detection holes in each group are respectively arranged at a symmetric included angle with the corresponding horizontal center line and vertical center line; through the cooperation of the pin with the first detection hole and the second detection hole, the detachable connection between the pin and the cylindrical body is realized.

[0008] Furthermore, for a porous spatial position detection device according to the present invention, the two second detection holes in each group are respectively arranged at a 15-degree symmetric included angle with the corresponding horizontal center line and vertical center line.

[0009] Furthermore, for a porous spatial position detection device according to the present invention, the pin includes a first pin and a second pin. The number of the first pins is the same as the number of the first detection holes, and the number of the second pins is the same as the number of the second detection holes. The detachable connection between the pin and the cylindrical body is realized by detachably inserting the first pin into the first detection hole or by detachably inserting the second pin into the second detection hole.

[0010] The present invention also discloses a manufacturing method of the above-mentioned porous spatial position detection device. The manufacturing method includes the manufacture of a simulation fitting and the manufacture of a positioning component. Among them, the manufacturing steps of the simulation fitting are as follows: First, select a metal or non-metal material that is not easily deformed as the raw material. According to the design drawing and assembly requirements of the workpiece product to be detected, use numerical control machining methods to manufacture a jacket-type or plug-type simulation fitting that matches the outer shape, dimensional elements, internal and external structures, assembly reference holes, hole position tolerances, hole pitches, hole diameters, and internal and external shape spatial position tolerances of the workpiece product to be detected. Finally, after precisely measuring the dimensions of the simulation fitting and the spatial position tolerances of each hole, it meets the assembly requirements. The manufacturing steps of the positioning component are as follows: Select the same material as the simulation fitting, and manufacture a positioning component that matches it according to the dimensions and shape elements of each hole in the simulation fitting. It is required that the positioning component can match the dimensions and shape elements of each hole in the simulation fitting and achieve detachable connection.

[0011] Further, in the manufacturing method of the present invention, the simulation fitting is a cylindrical body with openings at both ends. The cylindrical body is first manufactured by numerical control machining methods to match the outer shape structure of the workpiece product to be detected. Then, three first detection holes corresponding to the main hole positions of the workpiece product to be detected are made on the top surface of the cylindrical body. The three first detection holes are evenly distributed in a ring on the top surface of the cylindrical body. The hole pitch dimensions between the three first detection holes form an equilateral triangle. It is required that one of the first detection holes is arranged along the horizontal center line of its top surface and coincides with the reference hole of the workpiece product to be detected. After that, eight second detection holes corresponding to the secondary hole positions of the workpiece product to be detected are made on the side surface of the cylindrical body. The eight second detection holes are divided into four groups, and the four groups of second detection holes are evenly distributed in a ring on the side surface of the cylindrical body. The positioning groove is arranged along the vertical center line of its top surface and is symmetrically distributed on both sides of the first detection hole arranged along the horizontal center line of its top surface. Among them, two groups of second detection holes are symmetrically arranged along the horizontal center line of its top surface, and the other two groups of second detection holes are symmetrically arranged along the vertical center line of its top surface. The two second detection holes in each group are respectively arranged at a 15-degree symmetric included angle with the corresponding horizontal center line and vertical center line. The positioning component is a pin that matches the first detection hole and the second detection hole.

[0012] Further, in the manufacturing method of the present invention, the positioning component includes a first pin and a second pin. According to the dimensions and shape elements of the first detection hole, select the same material as the cylindrical body to manufacture three corresponding first pins. At the same time, according to the dimensions and shape elements of the second detection hole, select the same material as the cylindrical body to manufacture eight corresponding second pins.

[0013] The present invention also discloses a detection method for the above-mentioned porous spatial position detection device. The detection method is to first place the workpiece product to be detected on the platform, then assemble the simulation fitting with the product, and finally insert the positioning component into the corresponding first detection component and second detection component. When the first detection component and the second detection component match the corresponding positioning component without interference and clearance, it is qualified, that is, the assembly reference holes, hole position degrees, hole pitches, hole diameters, and internal and external shape spatial position dimensions of the product processing all meet the assembly use requirements; if there is a mismatch between the first detection component and the second detection component and the corresponding positioning component, interference and clearance occur, it is unqualified and cannot meet the assembly use requirements.

[0014] Adopting the porous spatial position detection device and its manufacturing and detection method of the present invention, compared with the existing manual detection and instrument measurement, its beneficial effects are as follows: Since the external shape structure of the simulation fitting matches the external shape structure of the workpiece product to be detected, by assembling the simulation fitting with the product and through the cooperation of the positioning component and the simulation fitting, it can not only meet the detection of the hole spatial position of porous products, but also verify the assembly usability after product processing. Thus, it can be seen that by using the detection device of the present invention, porous products can be detected, realizing the processing verification and rapid detection of the assembly usability of products, greatly improving the detection efficiency, meeting the measurement of a large number of porous products, having the advantages of convenient use and easy operation, and effectively reducing costs. This detection method can also be applied to the detection of the position degree and spatial position degree of other special-shaped parts and is suitable for popularization and application.

[0023] Such as Figures 1 to 3As shown in the figure, a porous spatial position detection device, the simulation fitting is selected as a cylindrical structure with openings at both ends, that is, the cylindrical body simulates part 1, and the positioning component 2 is a pin. The manufacturing method of the porous spatial position detection device includes the manufacturing of the cylindrical body simulation fitting 1 and the manufacturing of the positioning component 2. The manufacturing steps of the cylindrical body simulation fitting 1 are as follows: Select metals or non-metals such as steel, hard aluminum or nylon that are not easily deformed and have wear resistance, corrosion resistance, and high and low temperature resistance as raw materials, and manufacture outer sleeve type and plug type simulation parts that match the product's outer shape, dimensional elements, internal and external structures, assembly reference holes, hole position tolerances, hole distances, hole diameters, and internal and external shape spatial position tolerances. The manufacturing steps of the positioning component 2 are as follows: Select the same material as the cylindrical body and manufacture the corresponding one. Specifically, it includes the following steps:

[0024] 1. First, based on the product design drawing or product inspection requirements, analyze the relative position relationship between the dimensional elements and the spatial position of each hole, and the product's outer shape characteristics; according to the position tolerance dimensional elements between multiple holes that are not easily measured and the internal and external structure dimensional elements of the product, formulate the processing drawing of the simulation part; the processing drawing is an outer sleeve-shaped part, that is, the cylindrical body simulation part 1. For the current product being processed, when designing, select raw materials with an outer diameter of 231.26 mm, an inner hole (cylindrical body) diameter of 213.26 mm, an inner hole diameter at the top of the cylindrical body of 158 mm, a thickness of 10 mm at the top of the cylinder, and a wall thickness of 7.5 mm of the cylindrical body to manufacture, and the total height and the depth of the inner hole of the cylindrical body need to be determined according to the product height;

[0025] 2. Then, use the existing numerical control machining method to machine the selected cylindrical simulated part 1 in the shape of the outer contour: First, make 3 first detection holes 11 with a diameter of 8.5 mm on the top of the cylinder. The three first detection holes 11 correspond to the mounting holes on the top surface of the product cylinder at three equally spaced circumferences. The three first detection holes 11 are evenly distributed on the top of the cylinder, trisecting at 120°, and the hole pitch dimension is an equilateral triangle. For the 3 first detection holes 11 with a diameter of 8.5 mm, it is required that one of the holes is arranged along the horizontal center line of the top surface of the cylinder to make it a reference hole so that it can correspond to the reference hole on the product. Then, design two rectangular grooves 12 with a depth of 5 mm on the vertical center line of the top surface of the cylinder as the positioning reference components. It is required that the positioning reference components and the first detection hole 11 forming the reference hole are distributed in a cross shape. Finally, make 8 second detection holes 13 with a diameter of 5 mm on the outer cylindrical surface (corresponding to 8 holes with a diameter of 5 mm on the outer cylindrical surface of the product) and a diameter of 5 mm, and the hole pitch is 30.86 (corresponding to the hole pitch on the product). The 8 second detection holes 13 with a diameter of 5 mm on the cylindrical surface and the three first detection holes 11 trisecting at 120° on its top plane have a spatial angle of 30°, and are evenly distributed on both sides of the 15° symmetry of the center line dividing 360° into four equal parts of 90°, that is, the eight second detection holes 13 are divided into four groups, and the four groups of second detection holes 13 are evenly distributed in a ring on the side of the cylindrical body. The positioning groove is arranged along the vertical center line of its top surface and is symmetrically distributed on both sides of the first detection hole 11 arranged along the horizontal center line of its top surface. Among them, two groups of second detection holes 13 are symmetrically arranged along the horizontal center line of its top surface, and the other two groups of second detection holes 13 are symmetrically arranged along the vertical center line of its top surface. The two second detection holes 13 in each group are respectively arranged in a 15-degree symmetric angle relationship with the corresponding horizontal center line and vertical center line, so that a 30-degree angle relationship is formed between the two second detection holes 13 in the same group.

[0026] 3. Manufacture of the positioning component 2: First, make 3 first pins 21 with a diameter of 8.5 mm according to the 3 first detection holes 11 with a diameter of 8.5 mm. Then, make 8 second pins 22 with a diameter of 5 mm according to the 8 second detection holes 13 with a diameter of 5 mm. Finally, use precision measuring tools to detect the machined cylindrical simulated part 1 and the positioning component 2, and require that the machining quality meets the requirements. The first pin 21 is detachably inserted into the first detection hole 11, or the second pin 22 is detachably inserted into the second detection hole 13 to realize the detachable connection between the pin and the cylindrical body.

[0027] When using the porous spatial position detection device described in the present invention to detect porous products, the specific measurement method is as follows: First, place the workpiece product to be detected on the platform, then assemble the simulation fitting 1 with the product, and finally insert the first pin 21 and the second pin 22 into the corresponding first detection hole 11 and second detection hole 13. When each hole matches the corresponding pin without interference and clearance, it is qualified, that is, the assembly reference holes, hole position degrees, hole pitches, hole diameters, and internal and external shape spatial position dimensions of the product processing have all reached the assembly use requirements; if there is a mismatch between the pin and the corresponding detection hole, interference and clearance occur, it is unqualified and cannot meet the assembly use requirements. Embodiment

[0028] The difference between the porous spatial position detection device described in the present invention and that in Embodiment 1 is that the simulation fitting 1 is made into a square structure or other special-shaped structures that match the outer shape structure of the workpiece product to be detected. First, it is processed by numerical control machining methods, and then the machining quality is detected by precision measuring tools, so as to realize that its structure is the same as the outer shape structure of the workpiece product to be detected. Finally, the measurement is carried out in the same method to achieve the purpose of detecting it, so as to meet the detection of workpiece products with different outer shape structures to be detected.
