Technical Field
[0001] This utility model relates to the field of positioning and detection technology for machined products, specifically a positioning and detection device for machined products. Background Technology
[0002] Mechanical products require multiple processing steps during manufacturing. To ensure that the products meet the process requirements, it is necessary to perform precision and smoothness checks or internal flaw detection on the processed products. Testing equipment is used to inspect the produced workpieces to ensure the pass rate of the products delivered to the customer.
[0003] Currently, when inspecting machined products, it is necessary to fix the inspection equipment on the workpiece to achieve positioning inspection. For example, a patent with publication number CN217877403U discloses a positioning inspection device for machined products. It can be used to inspect products of the same series through a fixed frame with a fixed reference, and can be used to install the inspection plate with mounting holes to form the inspection of different products. However, since this positioning inspection device is only applicable to the inspection of workpieces with openings, it cannot be used for the positioning inspection of smooth surfaces and workpieces without openings, resulting in a limited scope of application. Therefore, a positioning inspection device for machined products is proposed to address the above problems. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, and to address the problem that existing positioning and detection devices are not suitable for positioning and detection of smooth surfaces and workpieces without openings, thus limiting their application scope, this utility model proposes a positioning and detection device for machined products.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a positioning and detection device for machining products, comprising a positioning frame; an adjustment component is installed in the positioning frame, the adjustment end of the adjustment component can move freely in the plane of the positioning frame, and a detection module is fixed under the adjustment end of the adjustment component.
[0006] Mounting holes are provided at all four corners of the positioning frame, and lifting components are fixed in each mounting hole. A suction cup is fixed to the lifting end of each lifting component.
[0007] The adjustment component has a first limiting plate and a second limiting plate arranged in a cross shape, and the first limiting plate and the second limiting plate are staggered vertically. A positioning cylinder is slidably arranged on the first limiting plate and the second limiting plate, and the detection module is fixed under the positioning cylinder.
[0008] The lifting assembly includes a fixed cylinder, in which a threaded rod is rotatably installed. The bottom end of the threaded rod is provided with a threaded sleeve that is threadedly connected to it, and the suction cup is fixed to the bottom end of the threaded sleeve.
[0009] Preferably, a first through groove is provided through the side of the positioning cylinder, and a first limiting plate is provided through the first through groove. A second through groove is provided through the side of the positioning cylinder, which is offset from the first through groove, and a second limiting plate is provided through the second through groove.
[0010] Preferably, the first limiting plate and the second limiting plate are respectively provided with a first pin hole and a second pin hole evenly distributed along their setting direction. A fixing plate is fixed inside the positioning cylinder, and the fixing plate is located above the first through groove and the second limiting plate. A hole is opened through the middle of the fixing plate, and a pin is installed through the hole. A baffle is fixed on the pin, and the baffle is located inside the positioning cylinder.
[0011] Preferably, a first spring is provided inside the positioning cylinder, and the first spring is located above the baffle. The bottom end of the pin is inserted through the corresponding first pin hole and second pin hole, and a pull plate is fixed to the top end of the pin.

[0015] The advantages of this utility model are:
[0016] 1. This utility model utilizes the principle that rotating the cap causes the threaded rod to rotate. With the limiting rib grooves working together, the rotating threaded rod moves the threaded sleeve upwards, causing the suction cup to firmly adhere to the workpiece surface. This allows for positioning and detection on workpiece surfaces without openings or with smooth surfaces using a detection module.
[0017] 2. By moving the bottom end of the pin rod out of the first and second pin holes, the positioning cylinder will slide using the first and second limiting plates. When the first and second limiting plates slide, they will slide in the guide groove using the sliders at their ends, thereby adjusting the detection position of the detection module.

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 scope of protection of the present utility model.
[0032] For examples, please refer to Figure 1-6 As shown, a positioning and detection device for machined products includes a positioning frame 1; an adjustment component 2 is installed inside the positioning frame 1, the adjustment end of the adjustment component 2 can move freely within the plane of the positioning frame 1, and a detection module 3 is fixed below the adjustment end of the adjustment component 2.
[0033] The positioning frame 1 has mounting holes 6 through each of its four corners. Each mounting hole 6 has a lifting component 4 fixed inside it, and each lifting end of the lifting component 4 has a suction cup 5 fixed inside it.
[0034] The adjustment component 2 is provided with a first limiting plate 23 and a second limiting plate 26 arranged in a cross shape, and the first limiting plate 23 and the second limiting plate 26 are staggered vertically. A positioning cylinder 21 is slidably arranged on the first limiting plate 23 and the second limiting plate 26, and the detection module 3 is fixed under the positioning cylinder 21.
[0035] The lifting assembly 4 includes a fixed cylinder 41, in which a threaded rod 46 is rotatably installed. The bottom end of the threaded rod 46 is provided with a threaded sleeve 45 that is threadedly connected to it, and the suction cup 5 is fixed to the bottom end of the threaded sleeve 45.
[0036] The positioning cylinder 21 has a through groove 22 through its side, and the first limiting plate 23 is disposed through the first through groove 22. The positioning cylinder 21 has a through groove 25 through its side, which is offset from the first through groove 22, and the second limiting plate 26 is disposed through the second through groove 25.
[0037] The first limiting plate 23 and the second limiting plate 26 are respectively provided with a first pin hole 24 and a second pin hole 27 evenly distributed along their setting direction. A fixing plate 28 is fixed inside the positioning cylinder 21, and the fixing plate 28 is located above the first through groove 22 and the second limiting plate 26. A hole is opened through the middle of the fixing plate 28, and a pin 29 is installed through the hole. A baffle 210 is fixed to the pin 29, and the baffle 210 is located inside the positioning cylinder 21.
[0038] The positioning cylinder 21 is provided with a first spring 211, which is located above the baffle 210. The bottom end of the pin 29 is inserted into the corresponding first pin hole 24 and second pin hole 27. The top end of the pin 29 is fixedly connected to a pull plate 212.
[0039] Guide grooves 214 are provided on the inner wall of the positioning frame 1, and sliders 213 that slide and limit within the guide grooves 214 are fixedly connected to the ends of the first limiting plate 23 and the second limiting plate 26.
[0040] A collar 42 is rotatably mounted on the upper end of the fixed cylinder 41. A rotating cap 43 is fixed on the collar 42, and the top end of the threaded rod 46 is fixed under the rotating cap 43. A bushing 44 is fixed inside the fixed cylinder 41, and the threaded sleeve 45 is slidably disposed inside the bushing 44.
[0041] The bushing 44 is provided with a limiting rib groove 47, and the outer wall of the threaded sleeve 45 is provided with a limiting rib 48 that slides and limits within the limiting rib groove 47.
[0042] Currently, when inspecting machined products, the inspection equipment needs to be fixed on the workpiece to achieve positioning inspection. However, this positioning inspection device is only suitable for inspecting workpieces with openings and cannot be used for positioning inspection of smooth or non-opening workpieces, resulting in a limited range of applications. In this solution, in the initial state, the first spring 211 will always push the baffle 210 downwards, so that the baffle 210 is attached to the fixed plate 28, and the bottom end of the pin 29 passes through the first pin hole 24 and the second pin hole 27 located below it to fix the position of the positioning cylinder 21. When in use, the positioning frame 1 is placed on the workpiece surface, so that the four suction cups 5 are attached to the workpiece surface. Then, the positioning frame 1 is pressed to make the four suction cups 5 initially adhere to the workpiece surface. Then, the four rotating caps 43 are rotated.
[0043] When the rotating cap 43 rotates, it will drive the threaded rod 46 to rotate. Under the limiting of the limiting rib groove 47 and the limiting rib groove 48, the threaded rod 46 rotates and drives the threaded sleeve 45 to move upward. The fixed cylinder 41 blocks the side of the suction cup 5, reducing the pressure inside the suction cup 5. This allows the suction cup 5 to be firmly attached to the surface of the workpiece. The detection module 3 can then be used to perform positioning detection on the surface of the workpiece without openings or on a smooth surface. When removing the suction cup 5, the rotating cap 43 is reversed to move the threaded sleeve 45 downward.
[0044] Furthermore, by pulling the pull plate 212, the bottom end of the pin 29 is moved out from the first pin hole 24 and the second pin hole 27. At this time, the positioning cylinder 21 can move freely on the plane within the positioning frame 1. When the positioning cylinder 21 moves, it will slide using the first limiting plate 23 and the second limiting plate 26. When the first limiting plate 23 and the second limiting plate 26 slide, they will slide in the guide groove 214 using the sliders 213 at their ends, thereby adjusting the detection position of the detection module 3. After adjustment, the pull plate 212 is released, so that the bottom end of the pin 29 passes through the first pin hole 24 and the second pin hole 27 below it again, so as to fix the position of the detection module 3, thereby achieving the function of positioning detection.
[0045] It achieves the function of positioning and detection on smooth or holeless workpieces, and the detection position can be adjusted according to the needs of use, effectively improving the scope of detection and ease of use.
[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
