Obviously, the embodiments described in this application are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the following drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0027] Example: Figure 1-7 As shown, a hole position detection fixture includes a base 10 and a lifting plate 20, the base 10 is used to store a product 30, the base 10 is provided with a detection surface, the detection surface is provided with a positioning pin 16 and a detection hole, the lifting plate 20 is movably mounted on the base 10, the lifting plate 20 is fixed with a detection column, the product 30 is provided with a positioning hole 31 and a processing hole 32, during detection, the product 30 is attached to the detection surface, the positioning pin 16 passes through the positioning hole 31 to position and fix the product 30, and the lifting plate 20 moves under the action of external force so that the detection column passes through the detection hole and the processing hole 32.
[0028] In this application, the base 10 is machined with a detection surface according to the shape of the product 30, that is, a contoured structure of the product 30 is machined on the base 10, and a positioning pin 16 is fixedly installed on the base 10 according to the position of the positioning hole 31 on the product 30. The diameter of the detection column is machined according to the processing hole 32 on the product 30 to ensure that the detection column can just pass through the processing hole 32. During the inspection, the product 30 is placed on the detection surface of the base 10 and the positioning pin 16 is inserted into the positioning hole 31 to quickly locate the position of the product 30. The product 30 is pressed down as much as possible, and then the inner surface of the product 30 is observed to be in contact with the detection surface of the base 10. If not, it means that the product 30 is unqualified. If the inner surface of the product 30 can be in contact with the detection surface of the base 10, the lifting plate 20 is manually pushed to extend the detection column from the detection hole. If the detection column can smoothly pass through the processing hole 32, it means that the position and aperture of the processing hole 32 on the product 30 meet the standard. Therefore, the hole position detection fixture in this application can quickly detect whether the shape of the product, the position and size of the processed hole, etc. meet the requirements, shorten the product inspection time, improve the product inspection efficiency, and can realize full inspection of the product, thereby improving the product shipment qualification rate. This application has low cost, easy use, fast inspection speed, and is very practical.
[0029] Optionally, the detection surface is a plane, an inclined surface or a curved surface, and the detection surface is a smooth surface. Optionally, two adjacent detection surfaces are connected by a curved surface, so that it can be used to detect the size of products with curvature.
[0030] like Figure 1 and Figure 5 As shown, the detection surface includes a first detection surface 11, a second detection surface 12, a third detection surface 13, a fourth detection surface 14, and a fifth detection surface 15. The second detection surface 12 is connected on both sides to the first detection surface 11 and the third detection surface 13, respectively. The fourth detection surface 14 is connected on both sides to the third detection surface 13 and the fifth detection surface 15, respectively. In this embodiment, five sequentially connected detection surfaces are used to form a contoured structure of the product 30, ensuring that when the product 30 is qualified, the inner surface of the product 30 can be in contact with the detection surfaces.
[0031] Alternatively, as Figure 1 and Figure 2 As shown, the angle between the first detection surface 11 and the second detection surface 12 is not greater than 90°, the angle between the second detection surface 12 and the third detection surface 13 is not less than 90°, the angle between the third detection surface 13 and the fourth detection surface 14 is an obtuse angle, and the angle between the fourth detection surface 14 and the fifth detection surface 15 is an obtuse angle.
[0032] Alternatively, as Figure 1 and Figure 6As shown, the second detection surface 12, the third detection surface 13 and the fourth detection surface 14 are all inclined surfaces, the first detection surface 11 and the fifth detection surface 15 are both planes, and the connection between the fourth detection surface 14 and the fifth detection surface 15 is an arc surface.
[0033] like Figure 1 As shown, the detection holes include a first detection hole 17 and a second detection hole 18. The first detection hole 17 is located on the first detection surface 11, and the second detection hole 18 is located on the fifth detection surface 15. Figure 3 and Figure 7 As shown, the product 30 is provided with two processing holes 32, and the two processing holes 32 correspond to the first detection hole 17 and the second detection hole 18 respectively. Figure 4 As shown, the detection column includes a first detection column 21 and a second detection column 22. The first detection column 21 is located in the first detection hole 17, and the second detection column 22 is located in the second detection hole 18. That is, the first detection column 21 is inserted into the first detection hole 17, and the second detection column 22 is inserted into the second detection hole 18. The first detection column 21 and the second detection column 22 are respectively used to detect the two processed holes 32 on the product 30.
[0034] like Figure 1 and Figure 3 As shown, the third detection surface 13 is fixed with the positioning pins 16, and the positioning pins 16 correspond one-to-one with the positioning holes 31. In a possible embodiment, four positioning pins 16 are fixed on the third detection surface 13, and correspondingly, four positioning holes 31 are provided on the product 30 to quickly locate and fix the product 30.
[0035] like Figure 4 As shown, the first end of the detection column is fixedly mounted on the lifting plate 20, and the second end of the detection column is inserted into the detection hole. When the lifting plate 20 moves, the detection column can move synchronously to extend out of the detection hole and the positioning hole 31.
[0036] like Figure 3 and Figure 4 As shown, the lifting plate 20 is located within the base 10 and is connected to the base 10 via a spring assembly 23. The first end of the spring assembly 23 is fixedly connected to the lifting plate 20, and the second end of the spring assembly 23 is fixedly connected to the base 10. The lifting plate 20 is mounted within the base 10 so that it can be raised and lowered by the spring assembly 23. When an operator pushes the lifting plate 20 upward, the lifting plate 20 moves upward, compressing the spring assembly 23. When the operator releases the lifting plate 20, the lifting plate 20 moves downward and returns to its original position under the action of the spring assembly 23. Optionally, the lifting plate 20 is provided with two sets of spring assemblies 23.
[0037] Optionally, the elastic component 23 includes a pin, a spring, and a plug, with the two ends of the spring fixedly connected to the pin and the plug, respectively. The first end of the spring is fixedly mounted to the lifting plate 20 via the plug, and the second end of the spring is fixedly mounted to the base 10 via the pin. The first end of the spring is fixed to the plug, which is fixedly mounted on the lifting plate 20, and the second end of the spring is fixed to the pin, which is fixedly mounted on the base 10.
[0038] The operation method of the hole position detection fixture in this application includes the following steps:
[0039] Step 1: Place the product 30 on the detection surface of the base 10, and insert the positioning pin 16 into the positioning hole 31 on the product 30;
[0040] Step 2: Press the product 30 downward to make the inner surface of the product 30 fit the inspection surface as much as possible. If the inner surface of the product 30 cannot fit the inspection surface, the shape of the product 30 is determined to be unqualified.
[0041] Step 3: If the inner surface of the product 30 fits the inspection surface, the operator pushes the lifting plate 20 upward, and the lifting plate 20 drives the inspection column to move synchronously. If the inspection column can smoothly pass through the processing hole 32 on the product 30, the product 30 is judged to be a qualified product, otherwise it is judged that the size or position of the processing hole 32 does not meet the requirements.
[0042] It should be noted that those skilled in the art may make a number of modifications and improvements without departing from the concept of this application, and these modifications and improvements are all within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be based on the appended claims.
