Description

Technical Field

[0001] This utility model relates to the field of gasket defect detection technology, specifically to an engine gasket defect detection device. Background Technology

[0002] Engine gaskets are important components in automobile engines used for sealing, damping, leak prevention, or adjusting clearances. They are usually made of metal, rubber, composite materials, etc., and require inspection by personnel during processing.

[0003] According to a public announcement (Announcement No.: CN219785671U), the above application describes a double-sided gasket surface defect detection mechanism. This mechanism uses a first annular ring to provide a mounting bracket for a first illumination lamp. The first illumination lamp provides unidirectional annular illumination on the gasket surface, resulting in more uniform color. Simultaneously, a first light-shielding backplate provides a background image for the first image detector. By utilizing the contrast between the dark environment inside the light-shielding shell and the bright areas of the gasket, the first image detector can easily identify defects on the gasket surface through image comparison. Furthermore, the transparent platform replaces the existing flipping mechanism, simplifying the detection process and improving detection efficiency.

[0004] However, in the aforementioned application, during testing, personnel directly place the shims on a transparent platform, relying solely on manual placement, making it difficult to ensure that their center position is aligned with the rotation axis. If the shims are placed off-center, it may cause wobbling during rotation or displacement of the image acquisition area, affecting testing accuracy. Due to the lack of automatic positioning or clamping devices, frequent manual intervention is required to adjust the shim position, reducing testing efficiency, especially noticeable in large-scale testing. Utility Model Content

[0005] The purpose of this invention is to provide an engine gasket defect detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an engine gasket defect detection device, comprising a workbench, a fixed frame fixed to the top of the workbench, a detection camera installed at the bottom of the fixed frame, and a transmission component and a positioning component provided on the surface of the workbench, the transmission component comprising: a placement plate and a placement groove;

[0007] The positioning component includes:

[0008] A cavity is used to stabilize its internal structure.

[0009] Gears are used to drive the fixed rod and the I-beam frame to move radially synchronously.

[0010] I-beams are used to position the gaskets.

[0011] Preferably, the cavity is formed inside the placement plate. A gear is rotatably connected to the inner wall of the cavity. A connecting hole is formed on the surface of the gear. A fixing rod is abutted against the inner wall of the connecting hole. An I-shaped frame is fixed to the end of the fixing rod away from the gear. The I-shaped frame passes through the placement groove and is slidably connected to the placement plate. A sliding groove is formed on the surface of the placement plate. A rack is slidably connected to the inner wall of the sliding groove. The sliding groove communicates with the cavity. The rack meshes with the gear. An abutting block is fixed to the top of the placement plate. Springs are fixed to the two sides of the I-shaped frame. The end of the spring away from the I-shaped frame is fixed to the inner wall of the cavity. The surface of the rack abuts against the arc-shaped surface of the abutting block. When the rack moves closer to the placement plate, it drives the gear to rotate forward. The inner wall of the connecting hole abuts against the surface of the fixing rod, driving the I-shaped frame to move radially synchronously, thereby positioning and straightening the gasket.

[0012] Preferably, the placement plate is slidably connected to the top of the workbench, a rack is fixed to the side of the placement plate away from the fixed frame, a motor is fixed to the bottom of the workbench, a half gear is rotatably connected to the top of the workbench, the rack meshes with the half gear, and L-shaped plates are fixed to both sides of the workbench. When the motor starts, the half gear intermittently meshes with the rack, causing the placement plate to move intermittently, which facilitates continuous testing of the pads.

[0013] Preferably, the end of the abutting block near the rack two is set to be arc-shaped, so that when it abuts against the surface of the rack two, it can drive the rack two to move.

[0014] Preferably, the connecting hole is arc-shaped, which can drive the fixing rod and the I-beam frame to move radially synchronously when the gear rotates, making it easy to position and straighten the gasket.

[0015] Preferably, the placement slot is located at the top of the placement plate to facilitate the placement of the gasket.

[0016] Compared with the prior art, the present invention provides an engine gasket defect detection device, which has the following beneficial effects:

[0017] 1. This engine gasket defect detection device, through the positioning component, when the gasket drives the transmission component, the surface of rack two abuts against the surface of the contact block, which causes rack two to move and drive the gear to rotate forward. Through the connecting hole and the fixing rod, the I-frame moves closer to each other to position and hold the gasket, without the need for manual intervention, thus improving the accuracy of subsequent inspections. When rack two is no longer in contact with the surface of the contact block, the gear reverses under the action of the spring, which drives the fixing rod and the I-frame to reset, thus releasing the gasket and making it easy to remove.

[0018] 2. The engine gasket defect detection device, through the transmission component, when the motor starts, the half gear intermittently meshes with the rack, which can drive the placement plate to move intermittently, so as to facilitate continuous detection of the gasket.

Detailed Implementation

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: an engine gasket defect detection device, including a workbench 1, a fixing frame 2 fixed on the top of the workbench 1, a detection camera 3 installed at the bottom of the fixing frame 2, and a transmission component 4 and a positioning component 5 provided on the surface of the workbench 1. The transmission component 4 includes: a placement plate 40 and a placement groove 42; the positioning component 5 includes: a cavity 50, a gear 51, a connecting hole 52, a fixing rod 53, an I-beam 54, a spring 55, a slide groove 56, a rack 57, and a contact block 58.

[0025] A cavity 50 is formed inside the placement plate 40. A gear 51 is rotatably connected to the inner wall of the cavity 50. A connecting hole 52 is formed on the surface of the gear 51. A fixing rod 53 abuts against the inner wall of the connecting hole 52. A I-shaped frame 54 is fixed to the end of the fixing rod 53 away from the gear 51. The I-shaped frame 54 passes through the placement groove 42 and is slidably connected to the placement plate 40. A sliding groove 56 is formed on the surface of the placement plate 40. A rack 57 is slidably connected to the inner wall of the sliding groove 56. The sliding groove 56 communicates with the cavity 50. The rack 57 meshes with the gear 51. A stop is fixed to the top of the placement plate 40. Springs 55 are fixed on both sides of the contact block 58 and the I-beam frame 54. The end of the spring 55 away from the I-beam frame 54 is fixed on the inner wall of the cavity 50. The end of the contact block 58 near the rack 57 is set in an arc shape, and the connecting hole 52 is set in an arc shape. The surface of the rack 57 abuts against the arc-shaped surface of the contact block 58. The rack 57 moves closer to the placement plate 40, driving the gear 51 to rotate forward. The inner wall of the connecting hole 52 abuts against the surface of the fixing rod 53, driving the I-beam frame 54 to move radially synchronously. The surface of the I-beam frame 54 abuts against the surface of the gasket, which can position and straighten the gasket, facilitating subsequent testing.

[0026] The placement plate 40 is slidably connected to the top of the workbench 1. A rack 43 is fixed to the side of the placement plate 40 away from the fixed frame 2. A motor 44 is fixed to the bottom of the workbench 1. A half gear 45 is rotatably connected to the top of the workbench 1. The rack 43 meshes with the half gear 45. L-shaped plates 41 are fixed to both sides of the workbench 1. The placement groove 42 is opened on the top of the placement plate 40. When the motor 44 starts, the half gear 45 intermittently meshes with the rack 43, which can drive the placement plate 40 to move intermittently, which facilitates continuous testing of the pads.

[0027] When defect inspection of the gasket is required, the gasket is placed into the placement slot 42. The motor 44 is then turned forward, causing the half-gear 45 to rotate continuously. When the half-gear 45 meshes with rack 43, the placement plate 40 moves the gasket synchronously. At this time, the surface of rack 57 contacts the arc-shaped surface of the contact block 58. As rack 57 moves closer to the placement plate 40, it drives gear 51 to rotate forward. The inner wall of the connecting hole 52 then contacts the surface of the fixing rod 53, synchronously driving the I-beam 54 to move radially. Simultaneously, spring 55 is compressed, and the surface of the I-beam 54 contacts the gasket surface, thus positioning and straightening the gasket for subsequent inspection. When the half-gear 45... When the gear 55 is not engaged with the rack 43, the spring 55 is released, which drives the gear 51 to reverse and reset. The fixing rod 53 drives the I-beam 54 to loosen the pad. At this time, the placement slot 42 is directly below the detection camera 3, and the detection work can be carried out. When the half gear 45 engages with the rack 43 again, it continues to drive the other set of pads to move, and the detection work can continue. When one end of the placement plate 40 touches the inside of the L-shaped plate 41, the placement plate 40 can no longer move. At this time, the motor 44 is turned off, the detected pad is taken out, and when the detection is required again, the pad is put back into the placement slot 42, the motor 44 is turned on to reverse, and the positioning and transmission detection work can be carried out again.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
