Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts detection, and particularly to an adjustable fixture for precision automotive parts detection. Background Art

[0002] Automotive parts detection is crucial in the automotive industry. There is a wide variety of automotive parts, covering engine components, transmission system parts, brake system components, etc. The detection process requires the use of advanced technologies and equipment to ensure that the quality of the parts meets strict standards. For example, precise measurement instruments are used to accurately measure the dimensions of the parts to ensure they are within the tolerance range. At the same time, material analysis techniques are employed to detect the material strength, hardness, corrosion resistance and other properties of the parts. Strict automotive parts detection helps to improve the safety, reliability and performance of vehicles. Unqualified parts may cause malfunctions during vehicle operation and even lead to serious safety accidents. Detection also promotes automotive manufacturers to improve product quality and enhance market competitiveness. In the field of automotive repair, accurate parts detection can help technicians quickly diagnose problems, select appropriate parts for replacement, and improve repair efficiency and quality. In short, automotive parts detection is an indispensable part of the automotive industry. In automotive parts detection, if the clamping mechanism cannot be automatically adjusted to adapt to parts of different sizes, it will bring many serious hazards.

[0003] During the detection of automotive parts of different sizes, stable and appropriate clamping is required. If the clamping mechanism cannot be automatically adjusted, smaller parts may not be firmly clamped and are prone to shaking or displacement during the detection process, affecting the measurement accuracy; while for larger parts, they may not be fully fixed, which will also cause deviations in the detection data. For example, when detecting the dimensional parameters of an automotive engine piston, inaccurate clamping may result in measured data such as diameter and height not matching the actual values, thus affecting subsequent assembly and engine performance.

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0032] As Figures 1 - 11As shown in the figure, the present invention provides a technical solution: an adjustable fixture for precision automobile parts inspection, including a frame 1. The top end of the frame 1 is fixedly connected with a panel 2. At the center of the upper surface of the panel 2, a strip-shaped hole 8 is opened. At the side of the upper surface of the panel 2, a circular hole 9 is opened. At the side of the lower surface of the panel 2, a first support rod 3 is fixedly connected. The end of the first support rod 3 is fixedly connected with a rotating mechanism 4. The rotating mechanism 4 includes a fixed frame 41. The fixed frame 41 is fixedly connected to the end of the first support rod 3. Inside the fixed frame 41, a motor 42 is fixedly connected. The output end of the motor 42 is installed with a first rotating rod 43 through a coupling. The end of the first rotating rod 43 is fixedly connected with a circular gear 44. The circular gear 44 penetrates the panel 2. A braking mechanism 5 is fixedly connected to the upper surface of the panel 2. By setting the rotating mechanism 4, after the precision automobile parts are placed and the power is connected, rotation can be generated. During the rotation process, the braking mechanism 5 can be moved, so as to automatically clamp the precision automobile parts, and the forward or reverse rotation effect can be achieved under control. By setting the first support rod 3 and the fixed frame 41, the motor 42 can be connected to the lower surface of the panel 2. By setting the motor 42, after the power is connected and turned on, the first rotating rod 43 can be rotated, so that the circular gear 44 can be rotated. By setting the braking mechanism 5, when the circular gear 44 rotates, a continuously increasing extrusion force can be applied to the precision automobile parts, so that the clamping mechanism 6 can tightly clamp the precision automobile parts. On the side of the upper surface of the panel 2 away from the braking mechanism 5, a clamping mechanism 6 is fixedly connected. The clamping mechanism 6 includes an extrusion plate 61. The extrusion plate 61 is located on the upper surface of the panel 2. The outer side of the extrusion plate 61 is fixedly connected with a connecting plate 63. The outer surface of the connecting plate 63 is fixedly connected with a sliding rod 64. The outer surface of the sliding rod 64 is sleeved with a limiting tube 65. The upper surface of the limiting tube 65 is fixedly connected to the upper surface of the panel 2. By setting the clamping mechanism 6, the precision automobile parts to be inspected can be placed, and during the continuous rotation of the circular gear 44, the precision automobile parts placed therein can be clamped. By setting the limiting tube 65, the sliding rod 64 can be limited, so that the sliding rod 64 can stably slide in the inner cavity of the limiting tube 65, and thus the extrusion plate 61 can generate a stable lateral movement. A twisting mechanism 7 is arranged on the lower surface of the panel 2. By setting the twisting mechanism 7, after the precision automobile parts are clamped, the torsion detection of the precision automobile parts can be automatically carried out.

[0033] The braking mechanism 5 includes a first limiting ring 51 which is fixedly connected to the upper surface of the panel 2. A sliding sleeve 52 is slidably connected to the inner cavity of the first limiting ring 51. By providing the first limiting ring 51, the sliding sleeve 52 can be limited, enabling the sliding sleeve 52 to rotate stably within the inner cavity of the first limiting ring 51. A second support rod 53 is fixedly connected to the outer side surface of the sliding sleeve 52. One side of the second support rod 53 away from the sliding sleeve 52 is fixedly connected to a one-way bearing 54. The outer ring of the one-way bearing 54 is fixedly connected to a circular gear ring 56, and the circular gear ring 56 meshes with the circular gear 44. By providing the one-way bearing 54, when the motor 42 rotates forward, both the circular gear ring 56 and the inner ring of the one-way bearing 54 can rotate, while when the motor 42 rotates in reverse, the inner ring of the one-way bearing 54 does not rotate. A threaded ring 55 is fixedly connected to the inner ring of the one-way bearing 54, and a reciprocating lead screw 57 is threadedly connected to the inner ring of the threaded ring 55. By providing the threaded ring 55 within the inner ring of the one-way bearing 54, when the motor 42 rotates forward and the circular gear ring 56 rotates, the threaded ring 55 rotates together, thereby causing the reciprocating lead screw 57 to move within the inner cavity of the threaded ring 55. When the motor 42 rotates in reverse, the threaded ring 55 does not rotate, and thus the reciprocating lead screw 57 does not move. By providing the reciprocating lead screw 57, it can move within the inner cavity of the threaded ring 55 when the threaded ring 55 rotates, and reciprocate when it moves to the end. A second rotating rod 58 is fixedly connected to the end of the reciprocating lead screw 57. The braking mechanism 5 further includes a fixed frame 59 which is fixedly connected to the strip-shaped hole 8 opened on the upper surface of the panel 2. A limiting frame 510 is fixedly connected to the upper surface of the fixed frame 59. By providing the fixed frame 59, the limiting frame 510 can be fixed, enabling the limiting frame 510 to be connected to the upper surface of the panel 2. A circular ring 512 is fixedly connected to the outer surface of the end of the second rotating rod 58. A rotating ring 511 is rotatably connected to the outer surface of the circular ring 512, and the rotating ring 511 is slidably connected to the inner cavity of the limiting frame 510. By providing the circular ring 512, the rotating ring 511 can be limited, enabling the rotating ring 511 to rotate on the outer surface of the circular ring 512. A track ring 514 is fixedly connected to the lower surface of the limiting frame 510, and a push rod 513 is fixedly connected to the lower surface of the rotating ring 511. The push rod 513 is movably connected to the strip-shaped hole 8. By providing the track ring 514 and the strip-shaped hole 8, the push rod 513 can be limited, enabling the push rod 513 to move stably horizontally when it moves along with the rotating ring 511. By providing the push rod 513, during the continuous movement of the second rotating rod 58, the push rod 513 can push the twisting mechanism 7, enabling the twisting mechanism 7 to move. A limiting rod 515 is fixedly connected to the end of the second rotating rod 58 away from the reciprocating lead screw 57.A connecting pipe 516 is rotatably connected to the outer surface of the limiting rod 515, and the end of the connecting pipe 516 is fixedly connected to the outer surface of the extrusion plate 61. By providing the limiting rod 515, the connecting pipe 516 can be limited, enabling the connecting pipe 516 to rotate relative to the limiting rod 515 and the second rotating rod 58. Thus, when the second rotating rod 58 rotates, the extrusion plate 61 does not rotate. During use, after placing the precision automotive parts, the operator connects the motor 42 to the power supply and turns on the switch of the motor 42, causing the first rotating rod 43 and the circular gear 44 to rotate. When the circular gear 44 rotates, it meshes with the circular tooth ring 56, causing the threaded ring 55 to rotate. When the threaded ring 55 rotates, it causes the reciprocating lead screw 57 to rotate and drives the second rotating rod 58 to move towards the clamping mechanism 6, ultimately causing the push rod 513 to move within the inner cavity of the track ring 514 and also causing the extrusion plate 61 at the end to move.

[0034] The inner surface of the extrusion plate 61 is fixedly connected with a first anti-slip plate 62. The outer surface of the extrusion plate 61 penetrates through a fixed box 66. The inner wall of the fixed box 66 is fixedly connected with a limiting frame 67. A movable rod 68 is slidably connected in the inner cavity of the limiting frame 67. One end of the movable rod 68 is fixedly connected with a first spring 69. The end of the first spring 69 is fixedly connected to the inner wall of the limiting frame 67. The end of the movable rod 68 away from the first spring 69 is fixedly connected with an elastic frame 610. The end of the elastic frame 610 is fixedly connected with a second anti-slip plate 611. The outer side of the fixed box 66 is fixedly connected with an elastic plate 612. By providing the limiting frame 67, the movable rod 68 can be limited, enabling the movable rod 68 to move within the inner cavity of the limiting frame 67. Thus, when the second anti-slip plate 611 presses against the precision auto parts, it can prevent the precision auto parts from being deformed by extrusion. By providing the first spring 69, elastic potential energy can be generated, and then the movable rod 68 drives the second anti-slip plate 611 to move towards the precision auto parts. The clamping mechanism 6 further includes a placement frame 613. The placement frame 613 is fixedly connected to the upper surface of the panel 2. The inner wall of the placement frame 613 is fixedly connected with a third anti-slip plate 614. The outer surface of the placement frame 613 penetrates through a limit box 615. A sliding plate 616 is slidably connected in the inner cavity of the limit box 615. One end of the sliding plate 616 located inside the placement frame 613 is fixedly connected with a fourth anti-slip plate 617. The lower surface of the end of the sliding plate 616 away from the fourth anti-slip plate 617 is fixedly connected with a third support rod 618. The end of the third support rod 618 is fixedly connected with a connection frame 619. The end of the connection frame 619 is fixedly connected with a tensioning frame 620. By providing the placement frame 613, it can cooperate with the extrusion plate 61 to wrap and extrude the precision auto parts during the movement of the extrusion plate 61, thereby clamping the precision auto parts. By providing the limit box 615, the sliding plate 616 can be limited, enabling the sliding plate 616 to move stably within the inner cavity of the limit box 615. During the extrusion of the precision auto parts, the sliding plate 616 drives the third support rod 618 and the connection frame 619 to move, and then the tensioning frame 620 pulls the bottom end of the precision auto parts. When in use, during the movement of the extrusion plate 61, due to the sliding of the sliding rod 64 within the inner cavity of the limit tube 65, the extrusion plate 61 drives the first anti-slip plate 62 and the second anti-slip plate 611 to press against the outer surface of the precision auto parts, and the other side of the precision auto parts presses against the third anti-slip plate 614. Finally, when the extrusion plate 61 continuously moves, the precision auto parts are tightly clamped.

[0036] Working principle: The operator places the precision automotive parts in the inner cavity of the placement frame 613. After placing the precision automotive parts, the operator connects the motor 42 to the power supply and turns on the switch of the motor 42, so that the first rotating rod 43 and the circular gear 44 rotate. When the circular gear 44 rotates, it will engage with the circular tooth ring 56, and then the threaded ring 55 rotates. When the threaded ring 55 rotates, it will cause the reciprocating screw rod 57 to rotate and drive the second rotating rod 58 to move towards the clamping mechanism 6, and finally make the push rod 513 move in the inner cavity of the track ring 514, and at the same time, the pressing plate 61 at the end also moves; during the movement of the pressing plate 61, due to the sliding of the sliding rod 64 in the inner cavity of the limiting tube 65, the pressing plate 61 drives the first anti-slip plate 62 and the second anti-slip plate 611 to squeeze the outer surface of the precision automotive parts, and makes the other side of the precision automotive parts squeeze against the third anti-slip plate 614. Finally, when the pressing plate 61 moves continuously, the precision automotive parts are tightly clamped; after the precision automotive parts are clamped, the push rod 513 will squeeze the pressing ring 74, and then the end of the hexagonal rod 72 is inserted into the inner cavity of the hexagonal frame 77. Then the operator controls the motor 42 to reverse, and then the rotating tube 71 rotates. During the rotation process, the rotating block 76 and the bevel gear 78 rotate, and the bevel tooth ring 712 rotates. Finally, the anti-slip ring 714 drives the bottom end of the precision automotive parts to rotate, achieving the effect of detecting the torque of the precision automotive parts.
