Description

Technical Field

[0001] This utility model belongs to the field of calibration technology for precision metal parts, and specifically relates to a calibration mechanism for precision metal parts. Background Technology

[0002] Precision metal parts are high-precision metal components manufactured using advanced processes such as CNC machining, precision casting, and electrical discharge machining. Their core characteristics include micron-level dimensional tolerances, low surface roughness, high geometrical accuracy, and high consistency and reliability. Their processing relies on multi-axis linkage equipment and precision measurement technology, enabling them to meet the stringent requirements for strength, corrosion resistance, and other properties in various applications. They are widely used in aerospace (e.g., engine blades), high-end automobiles (e.g., fuel injection components), electronic communications (e.g., chip connectors), and medical equipment (e.g., implantable devices). As core foundational components in high-end manufacturing, their quality directly determines the performance and lifespan of end-use equipment, making them a crucial link in driving industrial upgrading.

[0003] Existing calibration equipment for precision metal parts typically involves workers holding a rod and sliding it across the metal part to determine if it has been calibrated. However, because the rod is quite long, this significantly reduces the sensitivity to the surface of the metal part, sometimes leading to inaccurate detection. Furthermore, traditional methods lack marking functionality after the inspection is completed, so there may be some discrepancy between the calibrated and inspected areas, which greatly reduces the efficiency of processing metal parts. Utility Model Content

[0004] The purpose of this invention is to provide a calibration mechanism for precision metal parts. Its advantages are to improve the detection and calibration efficiency of metal parts, avoid errors caused by workers relying on their senses to judge the surface protrusions of metal parts, and avoid deviations between the detected protrusions and the calibration position, which would lead to low calibration efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a calibration mechanism for precision metal parts, including a base plate, two sets of sliding holes are provided on both sides of the base plate, a movable frame is slidably connected inside the four sets of sliding holes, a detection plate is slidably connected inside the movable frame, a rectangular hole is provided on the surface of the detection plate, and two sets of placement plates are provided inside the base plate.

[0006] The above technical solution allows the movable frame to move inside the sliding holes on the base plate surface, and the detection plate to move up and down inside the movable frame. The rectangular holes are used for the movement of the hollow tube.

[0007] The present invention is further configured such that a limiting rod is welded to one side surface of the movable frame, and the limiting rod is slidably connected to the detection plate, and a rotating shaft is rotatably connected to the upper end of the other side of the movable frame.

[0008] The above technical solution is adopted: when the handle rotates, it will drive the lead screw to rotate using the shaft. As the lead screw rotates, it will drive the detection rod to move downward. When the detection plate moves downward, it slides on the surface of the limit rod to limit and support the movement of the detection plate.

[0009] The present invention is further configured such that a lead screw is fixedly connected to the upper end of the rotating shaft, and the lead screw is threadedly connected to the detection plate.

[0010] The above technical solution is adopted as follows: as the lead screw rotates, the lead screw will drive the detection rod to move downward. When the detection plate moves downward, it slides on the surface of the limiting rod to limit and support the movement of the detection plate, so as to prevent the connection between the detection plate and the lead screw from being subjected to excessive pressure due to the long length of the detection plate.

[0011] The present invention is further configured such that a rotating handle is welded to the upper end of the lead screw, and a push rod is welded to one end of the movable frame.

[0012] By adopting the above technical solution: the rotating handle can provide a suitable force point for rotating the lead screw, and when the push rod is pushed to move, the push rod will drive the moving frame to move inside the sliding hole.

[0013] The present invention is further configured such that a hollow tube is slidably connected inside the rectangular hole, two sets of baffles are welded to the surface of the hollow tube, and a pusher is slidably connected inside the hollow tube.

[0014] The above technical solution is adopted as follows: when the push column is pressed, the push column will move downward inside the hollow tube. The baffle is used to limit the movement of the hollow tube to prevent the hollow tube from moving out of the rectangular hole. The limiting strip is used to limit the movement of the push column to prevent the push column from rotating randomly inside the hollow tube.

[0015] The present invention is further configured such that a limiting strip is welded to the surface of the push column, and the limiting strip is slidably connected to the inner wall of the hollow tube; a telescopic spring is connected between the push column and one of the baffles through a spring fixing component; and a marking block is glued to one end of the push column.

[0016] The above technical solution is as follows: When the push column is pressed, the push column will cause the marking block to be pressed against the raised part of the metal part. In this way, the erasable pigment on the surface of the marking block will mark the raised part. The marking block and the push column are bonded together and can be replaced when they cannot be used. After marking is completed, the telescopic spring will drive the push column and the marking block to move and reset.

[0017] In summary, this utility model has the following beneficial effects: 1. The design of the inspection board allows workers to more accurately inspect the raised parts on the surface of metal parts, avoiding judgment errors that may occur when relying solely on intuition. 2. Through the design of hollow tubes and marking blocks, protruding parts on the surface of metal parts can be detected more accurately, and the marking blocks can mark the protruding parts to prevent deviations between the detected and calibrated parts.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example 1: refer to Figure 1 , Figure 3 A calibration mechanism for precision metal parts includes a base plate 1, with two sets of sliding holes 2 on both sides of the base plate 1. A movable frame 4 is slidably connected inside the four sets of sliding holes 2. A detection plate 7 is slidably connected inside the movable frame 4. A rectangular hole 8 is opened on the surface of the detection plate 7. Two sets of placement plates 17 are arranged inside the base plate 1.

[0022] A limiting rod 10 is welded to one side of the movable frame 4, and the limiting rod 10 is slidably connected to the detection plate 7. A rotating shaft 5 is rotatably connected to the upper end of the other side of the movable frame 4.

[0023] A lead screw 6 is fixedly connected to the upper end of the rotating shaft 5, and the lead screw 6 is threadedly connected to the detection plate 7.

[0024] A handle 9 is welded to the upper end of the lead screw 6, and a push rod 3 is welded to one end of the moving frame 4.

[0025] Brief description of the usage process: When calibrating metal parts, the distance between the two sets of placement plates 17 is adjusted so that the two sets of placement plates 17 can be perfectly adapted to the size of the metal parts to be processed. After the metal parts are placed on the surfaces of the two sets of placement plates 17, the rotating handle 9 is rotated. When the rotating handle 9 rotates, it drives the lead screw 6 to rotate via the rotating shaft 5. As the lead screw 6 rotates, it drives the detection rod to move downward. The sliding of the detection plate 7 on the surface of the limiting rod 10 when it moves downward is to limit and support the movement of the detection plate 7, preventing the connection between the detection plate 7 and the lead screw 6 from being too long. Under high pressure, the design of the limit rod 10 can prevent the detection plate 7 from tilting downwards. When the detection plate 7 moves and sticks to the surface of the metal part (the detection plate 7 and the metal part are not pressed together, and the detection plate 7 is sticking to a normal flat part of the metal part), the push rod 3 is pushed. The push rod 3 will drive the moving frame 4 to move. The moving frame 4 will drive the detection plate 7 to slide on the surface of the metal part. As the detection plate 7 slides, when the detection plate 7 slides to a protruding part on the surface of the metal part, the protruding part will block the detection plate 7, so the detection plate 7 will not be able to move forward. At this time, the part that needs to be corrected is detected.

[0026] Example 2: refer to Figure 1-3 A hollow tube 11 is slidably connected inside the rectangular hole 8. Two sets of baffles 12 are welded to the surface of the hollow tube 11. A pusher 14 is slidably connected inside the hollow tube 11.

[0027] A limiting strip 15 is welded to the surface of the push column 14, and the limiting strip 15 is slidably connected to the inner wall of the hollow tube 11. The push column 14 and one of the baffles 12 are connected by a telescopic spring 13 through a spring fixing component. A marking block 16 is glued to one end of the push column 14.

[0028] Brief description of the usage process: When the detection plate 7 detects a protruding part on the surface of the metal part, the next step is to push the hollow tube 11 inside the rectangular hole 8 to move it on the surface of the metal part. Because the hollow tube 11 is small in size, it can be easily controlled by hand. Therefore, when the hollow tube 11 moves to the protruding part on the surface of the metal part, it can be clearly felt. When the protrusion is detected, the push post 14 is pressed. When the push post 14 is pressed, it will move downward inside the hollow tube 11. The baffle 12 is used to control the movement of the hollow tube 11. The limit bar 15 is used to limit the movement of the push post 14 to prevent it from rotating freely inside the hollow tube 11. When the push post 14 is pressed, it will cause the marking block 16 to press against the raised part of the metal part. In this way, the erasable pigment on the surface of the marking block 16 will mark the raised part. The marking block 16 is bonded to the push post 14 and can be replaced when it is not used. After marking is completed, the telescopic spring 13 will drive the push post 14 and the marking block 16 to move and reset.

[0029] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
