Description

Technical Field

[0001] This utility model belongs to the field of flatness detection technology, specifically relating to a device for detecting the flatness of die-cast parts. Background Technology

[0002] Die casting involves pouring liquid or semi-solid metal (such as copper, zinc, aluminum, or aluminum alloys) into the feed inlet of a die casting machine. Under high pressure, the molten metal fills the mold cavity and solidifies, thus obtaining a part with a specific shape and size. As an important type of metal part, die casting plays an irreplaceable role in modern industrial production.

[0003] Flatness inspection of die-cast parts is a crucial step in ensuring product quality. As disclosed in the patent application CN202323654784.3 entitled "Tooling for Flatness Inspection of Die-cast Parts," while setting up multiple sets of laser sensors to inspect the surface of the part improves inspection efficiency, it also increases equipment costs. Furthermore, if the detection ranges of the laser sensors are independent of each other, some parts of the part may not be inspected, leading to missed inspections and reduced die-cast part quality. Utility Model Content

[0004] Purpose of the utility model: To provide a device for detecting the flatness of die-cast parts, which solves the above-mentioned problems existing in the prior art.

[0005] Technical Solution: A die-casting flatness inspection device includes an operating table. A guide rail assembly is mounted on the top surface of the operating table. Sensing components are mounted at both ends of the guide rail assembly. A moving component is mounted above the guide rail assembly and is mounted on the operating table. The axial direction of the guide rail assembly is perpendicular to the axial direction of the moving component. A clamping component is mounted on the top surface of the guide rail assembly. The clamping component is used to clamp the die-casting to be inspected. Under the drive of the guide rail assembly, the clamping component reciprocates along the axial direction of the guide rail assembly. A laser sensor is mounted on the moving end of the moving component. Under the drive of the moving component, the laser sensor reciprocates along the axial direction of the moving component to inspect the surface flatness of the die-casting to be inspected. A control terminal is mounted on the upper end of the operating table. The control terminal is communicatively connected to the guide rail assembly, the sensing components, and the moving component.

[0006] Preferably, the guide rail assembly includes a mounting block disposed on the top surface of the operating table. An L-shaped mounting bracket is mounted on the side of the mounting block near the sensing component. A power source is mounted on one end of the mounting block, and the output end of the power source is connected to a reciprocating lead screw. A placement plate is engaged with the reciprocating lead screw. The clamping component is placed on the top surface of the placement plate. Telescopic hoses are respectively installed at both ends of a portion of the placement plate. One end of the telescopic hose is installed at the end of the mounting block, and the other end of the telescopic hose is connected to the end of the clamping component. Under the cooperation of the power source and the reciprocating lead screw, the placement plate is driven to reciprocate along the axial direction of the reciprocating lead screw.

[0007] Preferably, the sensing component includes two sets of L-shaped brackets. The lower ends of the L-shaped brackets are mounted on the top surface of the operating table and are located at both ends of the guide rail assembly. A proximity switch is installed on the top of the side wall of each set of L-shaped brackets near the guide rail assembly. Each set of proximity switches is communicatively connected to the control terminal.

[0008] Preferably, the clamping assembly includes a mounting plate, which is mounted on the top surface of the guide rail assembly. Two sets of arc-shaped blocks are mounted on one end of the top surface of the mounting plate near the guide rail assembly. The arc-shaped blocks are located at the apex corners of the mounting blocks. Several clamping parts are mounted on both ends of the mounting plate. The clamping parts and the arc-shaped blocks are on the same side and are arranged opposite to each other. At least two sets of support blocks are mounted between the clamping parts. The support blocks are arranged in a rectangular array between the clamping parts.

[0009] Preferably, the clamping part includes a small telescopic rod, which is mounted on the top surface of the mounting plate. A pressure rod is mounted on the top surface of the small telescopic rod. The pressure rod is mounted to the moving end of the small telescopic rod via a connector.

[0012] Beneficial effects: This utility model relates to a die-casting flatness inspection device. It uses a clamping assembly to hold and fix the part to be inspected, and under the action of a guide rail assembly, drives the part to be inspected to reciprocate along the central axis of the guide rail assembly. Simultaneously, with the cooperation of a moving assembly, it drives a laser sensor to reciprocate above the part to be inspected along the central axis of the moving assembly, so that the part to be inspected and the laser sensor form four degrees of freedom of movement in two mutually perpendicular directions. This allows the laser sensor to achieve comprehensive inspection of the surface of the part to be inspected, thus efficiently completing the flatness inspection of die-castings. It also simplifies the structure of the inspection device and reduces equipment costs. Attached Figure Description

[0023] like Figures 1 to 5As shown, this utility model provides a technical solution: a die-casting flatness detection device, including an operating table 1, a guide rail assembly 2, a sensing assembly 3, a moving assembly 4, a clamping assembly 5, a laser sensor 6, a control terminal 7, and a display screen 8; the guide rail assembly 2 is mounted on the top surface of the operating table 1, and sensing assemblies 3 are respectively mounted at both ends of the guide rail assembly 2. The moving assembly 4 is mounted above the guide rail assembly 2 and is mounted on the operating table 1. The axial direction of the guide rail assembly 2 is perpendicular to the axial direction of the moving assembly 4. The clamping assembly 5 is mounted on the top surface of the guide rail assembly 2 and is used to clamp the die-casting to be inspected. The clamping assembly 5 reciprocates along the axial direction of the guide rail assembly 2 under the drive of the guide rail assembly 2. The moving end of the moving assembly 4 is equipped with a laser sensor 6, which reciprocates along the axial direction of the moving assembly 4 under the drive of the moving assembly 4. The device moves repeatedly to detect the surface flatness of the die-cast part. Under the action of the sensing component 3, the movement range of the guide rail assembly 2 clamping component 5 along the central axis of the guide rail assembly 2 is limited, so that the surface of the die-cast part to be tested on the clamping component 5 can be fully detected by the laser sensor 6 installed on the moving end of the moving component 4. A control terminal 7 is installed on the upper end of the operating table 1. The control terminal 7 is communicatively connected to the guide rail assembly 2, the sensing component 3 and the moving component 4. By controlling the control terminal 7, the guide rail assembly 2, the sensing component 3 and the moving component 4 can be controlled to achieve a comprehensive detection of the surface flatness of the die-cast part in the clamping component 5. This can efficiently complete the flatness detection of the die-cast part, while simplifying the structure of the detection device and reducing equipment costs. The display screen 8 is installed above the operating table 1. The display screen 8 is communicatively connected to the control terminal 7 and is used to display the detection data of the laser sensor 6.

[0024] In a further embodiment, the guide rail assembly 2 includes a mounting block 21, which is mounted on the top surface of the operating table 1. An L-shaped mounting bracket 22 is mounted on the side of the mounting block 21 near the sensing component 3. A power source 23 is mounted on one end of the mounting block 21. In this embodiment, the power source 23 is a drive motor. The output end of the power source 23 is connected to a reciprocating lead screw, and a placement plate 24 is engaged with the reciprocating lead screw. That is, under the cooperation of the drive motor and the reciprocating lead screw, the placement plate 24 is driven to reciprocate along the axial direction of the reciprocating lead screw. The clamping assembly 5 is mounted on the top surface of the placement plate 24. Telescopic hoses 25 are respectively mounted on both ends of the placement plate 24. One end of the telescopic hose 25 is mounted on the end of the mounting block 21, and the other end of the telescopic hose 25 is connected to the... At the end of the clamping assembly 5, the placement plate 24, under the cooperation of the power source 23 and the reciprocating screw, drives the placement plate 24 to move back and forth along the axial direction of the reciprocating screw, and uses the telescopic hose 25 to wrap the reciprocating screw to prevent foreign objects from falling in and causing the placement plate 24 to be unable to move to the predetermined position, thus preventing the die-casting part to be inspected from being fully inspected. The sensing assembly 3 includes two sets of L-shaped brackets 31. The lower end of the L-shaped brackets 31 is installed on the top surface of the operating table 1. The L-shaped brackets 31 are respectively located at both ends of the guide rail assembly 2.

Each set of proximity switches 32 is communicatively connected to the control terminal 7. The position of the L-shaped mounting bracket 22 is detected by the proximity switch 32 to control the start and stop of the drive motor.

[0025] In a further embodiment, the clamping assembly 5 includes a mounting plate 51, which is mounted on the top surface of the guide rail assembly 2. Two sets of arc-shaped blocks 52 are mounted on one end of the top surface of the mounting plate 51 near the guide rail assembly 2. The arc-shaped blocks 52 are located at the apex corners of the mounting blocks 21, and their positions are defined by the arc-shaped blocks 52. Several clamping parts are mounted on both ends of the mounting plate 51. In this embodiment, six sets of clamping parts are used. The clamping parts and the arc-shaped blocks 52 are on the same side and are arranged opposite each other. At least two sets of support blocks 53 are installed between the clamping parts. In this embodiment, two sets of support blocks 53 are used. The support blocks 53 are arranged in a rectangular array between the clamping parts, supporting the middle position of the die-casting part to be inspected. Each clamping part includes a small telescopic rod 54. A small telescopic rod 54 is installed on the top surface of the mounting plate 51. A pressure rod 55 is installed on the top surface of the small telescopic rod 54. The pressure rod 55 is installed on the moving end of the small telescopic rod 54 through a connector. The height of the pressure rod 55 is adjusted by the small telescopic rod 54 to accommodate die-cast parts of different thicknesses. The pressure rod 55 is perpendicular to the central axis of the small telescopic rod 54. A bolt 56 is engaged at the end of the pressure rod 55 away from the small telescopic rod 54. A support rod 57 is installed on the side of the small telescopic rod 54. The support rod 57 is located below the end of the pressure rod 55. The bolt 56 is operatively abutted against the top of the support rod 57. That is, after the die-cast part to be tested is placed on the support rod 57, one end of the die-cast part to be tested abuts against the arc-shaped block 52. The small telescopic rod 54 and the bolt 56 are used to abut and limit the die-cast part to be tested for inspection.

[0026] In a further embodiment, the moving component 4 includes a truss 41, which is mounted on the operating table 1 and located above the guide rail assembly 2. A servo motor 42 is mounted on one top end of the truss 41, and a transmission screw 43 is mounted on the output end of the servo motor 42. A moving block 44 is meshed with the transmission screw 43. With the cooperation of the servo motor 42 and the transmission screw 43, the moving block 44 is driven to reciprocate on the transmission screw 43. A mounting rod 45 is mounted longitudinally on the side of the moving block 44, and a fixing block 46 is mounted on the lower end of the mounting rod 45. The laser sensor 6 is mounted on the lower end of the fixing block 46. Thus, when the moving block 44 is moved, the laser sensor 6 is moved to detect the flatness of the surface of the die-cast part to be inspected.
