Description
Technical Field
[0001] This invention relates to the field of testing fixture technology, and in particular to a two-in-one controller circuit board testing fixture. Background Technology
[0002] The controller is installed on the chassis of a large truck. As a key electronic control unit of the vehicle, it collects and processes steering and braking-related signals in real time through an internal circuit board, and precisely drives the steering assist and braking actuators. It effectively improves the steering control and braking safety of heavy trucks and is a core automotive component that ensures the stable and reliable operation of commercial vehicles.
[0003] To ensure the performance of the controller, the component needs to be tested. Circuit board testing methods generally consist of test fixtures and test control systems. During the test, there are two methods to connect the test fixture and the circuit under test through a bed of test pins: one is manual pressing, where the tester manually presses down the test fixture to ensure good contact between the circuit under test and the bed of test pins; the other is pneumatic connection, where pressing the test button causes the cylinder to directly press down the pressure component.
[0004] The shortcomings of the existing technology are that, during the circuit board testing process, the circuit board on the carrier board is connected to the test route through the pressure plate. The limiting component in the pressure plate needs to be matched according to the distribution of the electrical components on the circuit board. This results in the pressure plate needing to be replaced differently when using different circuit boards, which limits the use of the pressure plate and the limiting component, and restricts the use of the circuit board and the pressure plate. Summary of the Invention
[0005] The purpose of this invention is to provide a two-in-one controller circuit board testing fixture. A switching mechanism connected to the drive components transmits power to the mounting frame and the moving platform, enabling the moving platform, supported by a support component, to move the mounting frame to any position on the bottom surface of the lower pressure plate. A positioning head fixed to the bottom of the moving platform is used to locate the adsorption position of the limiting component. The switching mechanism switches the power from the moving platform to the mounting frame, allowing the mounting frame to quickly adsorb and fix the limiting component to the lower pressure plate. This allows the lower pressure plate to adjust the position of the limiting component according to the requirements of the circuit board, improving the applicability of the lower pressure plate and avoiding the limitations of a dedicated lower pressure plate for circuit boards.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0038] Reference Figures 1-9 A two-in-one controller circuit board testing fixture includes a base 1, on which a pneumatic telescopic pump 2 is mounted; a top plate 3 is fixedly connected to the top of the pneumatic telescopic pump 2, and a lower pressure plate 4 is fixedly connected to the top plate 3 via a connecting column 31; a support member 5 is provided at the bottom of the lower pressure plate 4, and a movable platform 7 is provided in the support member 5, enabling the platform 7 to move to any position on the bottom surface of the lower pressure plate 4 via the support member 5; a mounting frame 10 is provided at the top of the platform 7, and a limiting member 11 for limiting the circuit board is provided at the top of the mounting frame 10; one end of the platform 7... A driving component 8 is provided, which transmits the drive frame 10 and the moving platform 7 through a switching mechanism 9. When the switching mechanism 9 transmits the drive component 8 to the drive frame 10, the drive frame 10 drives the limiting component 11 to move and lock it with the lower pressure plate 4, so that the limiting component 11 can be quickly adsorbed and fixed to the lower pressure plate 4 through the drive frame 10. When the switching mechanism 9 transmits the drive component 8 to the moving platform, the moving platform moves to any position on the bottom surface of the lower pressure plate 4 through the support component 5, so that the moving platform 7 drives the limiting component 11 to be adsorbed and fixed at any position on the lower pressure plate 4.
[0039] Specifically, the pneumatic telescopic pump 2, symmetrically fixed to the base 1, drives the top plate 3 to move up and down via telescopic movement. The lower pressure plate 4, fixed to the bottom of the top plate 3 via a connecting column 31, is used to fix the limiting member 11. The limiting member 11 is fastened to the lower pressure plate 4 through an adsorption and fixing structure, allowing the limiting member 11 to press down the circuit board placed on the carrier plate 6 and connect it to the detection circuit in the base 1, facilitating rapid detection of the circuit board. The support member 5, fixed to the bottom of the lower pressure plate 4, limits the movement of the moving stage 7. The moving stage 7, powered by the drive member 8, moves laterally or longitudinally along the support arm 55 in the support member 5, enabling the moving stage 7 to reach any position within the surface area of the lower pressure plate 4 in conjunction with the support member 5. A mounting bracket is installed on the moving stage 7. The limiting member 11 is quickly adsorbed and connected to the lower pressure plate 4. The device transmits power to the mounting frame 10 and the moving platform 7 respectively through the switching mechanism 9 connected to the driving member 8. The moving platform 7 can drive the mounting frame 10 to any position on the bottom surface of the lower pressure plate 4 under the support of the supporting member 5. The positioning head 12 fixed to the bottom end of the moving platform 7 is used to position the adsorption position of the limiting member 11. The switching mechanism 9 switches the power from the moving platform 7 to the mounting frame 10, so that the mounting frame 10 can quickly adsorb and fix the limiting member 11 to the lower pressure plate 4. The lower pressure plate 4 can adjust the position of the limiting member 11 at different positions according to the needs of the circuit board, thereby improving the applicability of the lower pressure plate 4 and avoiding the limitation of the lower pressure plate 4 being dedicated to the circuit board.
[0040] The lower pressure plate 4 is symmetrically fixed with frame 51 at both ends. The frame 51 has an inner slide groove 52. The inner slide groove 52 is movably mounted with a moving part 53. The bottom end of the moving part 53 is provided with a pull rod 54. The bottom end of the pull rod 54 is fixed with a support arm 55. The two support arms 55 are in a cross structure, and one end of the support arm 55 is provided with a toothed groove 551. Specifically, the frame 51 symmetrically fixed at both ends of the lower pressure plate 4 is rectangular. The inner slide groove 52 is movably mounted with a movable plate 531. The movable wheels 532 rotatably connected at both ends of the movable plate 531 are attached to the inner wall of the inner slide groove 52. The fixed arm 533 fixed to the movable plate 531 is used to limit the position of the pull rod 54. The positional relationship between the pull rod 54 and the fixed arm 533 can be achieved by bolt fastening or pneumatic telescopic structure. The support arm 55 fixed to the bottom end of the pull rod 54 is used to support the moving platform 7, so that the moving platform 7 can move laterally or longitudinally along the support arm 55.
[0041] A drive motor 81 is fixedly connected to the top of the moving platform 7. One end of the drive motor 81 has a convex shaft 82, and the other end has an output gear 83. A sleeve shaft 97 is fitted onto the convex shaft 82. Bevel gears 98 are symmetrically fixed to both ends of the sleeve shaft 97. A sleeve plate 96 is fixedly connected to one end of the sleeve shaft 97, and a connecting rod 93 is fixedly connected to one end of the sleeve plate 96. A fixing plate 92 is fixedly connected to one end of the connecting rod 93, and a hydraulic pump 91 is fixedly connected to one end of the fixing plate 92, and the hydraulic pump 91 is fixedly connected to the moving platform 7. A bevel gear 95 meshes with one end of the output gear 83. A rectangular shaft 99 passes through the bevel gear 95. Paddles 94 are symmetrically provided at both ends of the bevel gear 95, and the paddles 94 are fixedly connected to the connecting rod 93. The top end of the rectangular shaft 99 is fixedly... A pulley 910 is connected; a belt 911 is fitted onto one end of pulley 910, and a pulley 912 is fitted onto the end of belt 911 away from pulley 910. A rotating shaft 913 is fixed to the bottom end of the pulleys, and a pulley 914 is located at the bottom end of the rotating shaft 913. A belt 915 is fitted onto pulley 914, and a turntable 101 is fitted onto the end of belt 915 away from pulley 912. A semi-circular ring 102 is fixed to the top of the turntable 101, and a toothed groove 103 is opened at the top of the semi-circular ring 102. A bevel gear 108 meshes with one end of the toothed groove 103, and a connecting shaft 109 is fixed to one end of the bevel gear 108. A bevel gear 1010 is fixed to one end of the connecting shaft 109. (Details omitted) The drive motor 81 is a dual-axis motor. The bottom of the drive motor 81 has a convex shaft 82 for output, and its top output is via an output gear 83. When the hydraulic pump 91 pushes the connecting rod 93, which is fixed to the base plate, to move in a directional manner, the connecting rod 93 drives the sleeve plate 96 and the lever 94 to move in three states. In the first state, the connecting rod 93 moves downwards, and the sleeve shaft 97, which is fixed to the sleeve plate 96, drives the two bevel gears 98 to move downwards. The bevel gear at the bottom of the sleeve shaft 97 meshes with the tooth groove 551 of the transverse support arm 55. Under the drive of the drive motor 81, the moving table 7 moves along the transverse support arm 55. In the second state, the connecting rod 93 drives the two bevel gears 98 in the sleeve shaft 97 of the sleeve plate 96 to separate from the support arm 55. In the first state, the lever 94 at the top of the linkage 93 drives the bevel gear 95 to mesh with the output gear 83. The bevel gear 95 drives the rectangular shaft 99 to rotate. The rectangular shaft 99 drives the turntable 101 to rotate through the pulley and belt, so that the mounting frame 10 will fix the limiting member 11 to the lower pressure plate 4 at a fixed point. In the third state, the linkage 93 drives the bevel gear 98 at the top of the sleeve shaft 97 in the sleeve plate 96 to mesh with the tooth groove 551 opened in the longitudinal support arm 55. Under the rotation of the cam shaft 82 of the drive motor 81, the moving table 7 moves along the longitudinal support arm 55. Under the switching mechanism 9, the moving table 7 moves the limiting member 11 to any position of the lower pressure plate 4 and is quickly fixed by the mounting frame 10.
[0042] The mounting frame 10 includes a directional block 104, within which a sliding block 105 is slidably connected. A horizontal arm 1014 is fixedly connected to one end of the sliding block 105. A support rod 106 is provided at the bottom end of the horizontal arm 1014 and is fixedly connected to the sliding block 105. A rotating wheel 107 is sleeved on one end of the support rod 106, and the rotating wheel 107 abuts against a semi-circular ring 102. The support rod 106 passes through the rotating wheel 107 and is movably connected to a bevel gear 108. A rotating cylinder 1012 is movably connected to one end of the horizontal arm 1014. A bevel gear 1011 is fixedly connected to the bottom end of the rotating cylinder 1012, passing through the horizontal arm 1014. The bevel gear 1011 meshes with the spur gear 1011 and the bevel gear 1010. Limiting posts 1013 are symmetrically fixed to the top of the rotating cylinder 1012. Specifically, the directional block 104 in the mounting frame 10 has a rectangular structure and is fixed on the moving platform 7. The sliding block 105, which is slidably connected inside the directional block 104, is rotatably connected to the rotating wheel 107 via the support rod 106. The top surface of the semicircular ring 102 and the surface of the turntable 101 are provided with inclined surfaces. When the turntable 101 is driven by the drive motor 81 to rotate, the rotating wheel 107 moves up and down along the structure formed by the turntable 101 and the semicircular ring 102. The support rod 106 passes through the rotating wheel 107 and is movably connected to the bevel gear 1010, which meshes with the tooth groove 103 opened in the semicircular ring 102. When the rotating wheel 107 is located on the semicircular ring 102, the bevel gear 108 drives the rotating cylinder 1012 to rotate through the meshing bevel gear 1011, so that the rotating cylinder 1012 can adsorb and fix the limiting member 11 and the lower pressure plate 4 inside the cylinder, thereby realizing the flexibility of adsorbing and fixing the limiting member 11 and the lower pressure plate 4.
[0043] The limiting component 11 includes an abutment head 1101, a straight rod 1102 fixedly connected to the top of the abutment head 1101, a suction cup 1107 rotatably connected to the top of the straight rod 1102, and a threaded groove 1105 opened at the end of the straight rod 1102 near the suction cup 1107; a sleeve 1103 is sleeved on the straight rod 1102, and positioning strips 1104 are symmetrically fixedly connected to the bottom end of the sleeve 1103, and the positioning sleeve engages with the limiting post 1013 for limiting. A retaining ring 1108 is fixedly connected to the top of the sleeve 1103, and a nut 1106 is fixedly connected to the end of the sleeve 1103 near the retaining ring 1108, and the nut 1106 is adapted to the threaded groove 1105; specifically, the retaining head 1101 in the limiting member 11 is placed inside the rotating cylinder 1012. When the rotating wheel 107 drives the rotating cylinder 1012 to rise along the semi-circular ring 102, the top of the retaining head 1101 rotates through the straight rod 1102. The suction cup 1107, which is dynamically connected, abuts against the lower pressure plate 4 and discharges the air between the suction cup 1107 and the lower pressure plate 4. When the bevel gear 1010 meshes and rotates with the tooth groove 103, the bevel gear 1011 meshes with the bevel gear 95 to drive the rotating cylinder 1012 to rotate. The contact head 1101 located in the rotating cylinder 1012 drives the straight rod 1102 to rotate. The nut 1106 threaded through the threaded groove 1105 of the straight rod 1102 drives the sleeve 1103 to move in a direction under the limitation of the sleeve 1103. The two positioning strips 1104 fixed to the bottom end of the sleeve 1103 limit the sleeve 1103 between the two limiting posts 1013. The abutment ring 1108 fixed to the top end of the sleeve 1103 abuts against the lower pressure plate 4, making the suction cup 1107 and the lower pressure plate 4 more firmly adsorbed and improving the ease of use of the limiting part 11.
[0044] Working principle: The pneumatic telescopic pump 2, symmetrically fixed to the base 1, drives the top plate 3 to move up and down by telescopic movement. The bottom end of the top plate 3 is fixedly connected to the lower pressure plate 4 via the connecting column 31 to fix the limiting member 11. The limiting member 11 is fastened to the lower pressure plate 4 through an adsorption and fixing structure, so that the limiting member 11 presses down the circuit board placed on the carrier plate 6 and connects it with the detection circuit in the base 1, which facilitates the rapid detection of the circuit board. When the hydraulic pump 91 pushes the connecting rod 93 fixed to the base plate to move in a directional manner, the connecting rod 93 drives the sleeve plate 96 and the lever 94 to move and has three states. In the first state, the connecting rod 93 moves downward and the sleeve plate 96 moves downward. The fixed sleeve shaft 97 drives the two bevel gears 98 to move downwards. The bevel gear at the bottom of the sleeve shaft 97 meshes with the tooth groove 551 of the transverse support arm 55. Driven by the drive motor 81, the moving table 7 moves along the transverse support arm 55. In the second state, the connecting rod 93 drives the two bevel gears 98 in the sleeve shaft 97 of the sleeve plate 96 to separate from the support arm 55. The lever 94 at the top of the connecting rod 93 drives the bevel gear 95 to mesh with the output gear 83. The bevel gear 95 drives the rectangular shaft 99 to rotate. The rectangular shaft 99 drives the turntable 101 to rotate through the pulley and belt. When the rotating wheel 107 drives the rotating cylinder 10 along the semicircular ring 102... When the 12 rises, the suction cup 1107, rotatably connected to the top of the contact head 1101 via the straight rod 1102, presses against the lower pressure plate 4, expelling the air between the suction cup 1107 and the lower pressure plate 4. When the bevel gear 1010 meshes with the tooth groove 103, it drives the rotating cylinder 1012 to rotate through the meshing of the bevel gear 4 95 via the bevel gear 3 1011. The contact head 1101 located inside the rotating cylinder 1012 drives the straight rod 1102 to rotate. The nut 1106 threaded into the threaded groove 1105 of the straight rod 1102 drives the sleeve 1103 to move in a directional manner under the limiting position of the sleeve 1103. The two fixed ends of the sleeve 1103 are fixed to the bottom. Position bar 1104 limits sleeve 1103 between two limiting posts 1013. The abutment ring 1108 fixed at the top of sleeve 1103 abuts against the lower pressure plate 4, making the suction cup 1107 more firmly adsorbed between the suction cup 1107 and the lower pressure plate 4. In the third state, the linkage rod 93 drives the bevel gear 98 at the top of the sleeve shaft 97 in the sleeve plate 96 to mesh with the tooth groove 551 opened in the longitudinal support arm 55. Under the rotation of the cam shaft 82 of the drive motor 81, the moving table 7 moves along the longitudinal support arm 55. Under the switching mechanism 9, the moving table 7 moves the limiting member 11 to any position of the lower pressure plate 4 and is quickly adsorbed and fixed by the mounting bracket 10.
