Description
Technical Field
[0001] This utility model relates to the field of server testing, and in particular to a server whole board simulation test and maintenance fixture. Background Technology
[0002] In the manufacturing and maintenance of servers, the testing and maintenance of entire server boards (such as motherboards and power boards) are crucial for ensuring equipment performance stability. Currently, testing and maintenance fixtures for entire server boards typically need to meet requirements such as board fixation, precise test point alignment, and thermal management. However, existing testing and maintenance fixtures still have the following shortcomings in practical applications:
[0003] Deficiencies of existing technology:
[0004] The circuit board fixing mechanism lacks flexibility: Traditional tooling circuit board fixing structures are mostly fixed or simple clamping, which are difficult to adapt to circuit boards of different sizes and models. In addition, uneven pressure during the fixing process may cause the circuit board to deform, affecting the test accuracy.
[0005] Inconvenient adjustment of test components: Existing tooling test heads are usually fixed or can only move in one direction, which cannot flexibly cover multiple test points on the circuit board. Especially for server boards with complex wiring, the circuit board needs to be disassembled and reassembled or the tooling position adjusted multiple times.
[0006] Based on this, we propose a server board simulation test and maintenance fixture. Utility Model Content
[0007] To address the technical problems of insufficient flexibility in circuit board fixing mechanisms and inconvenient adjustment of test components, this utility model provides a server whole board simulation test and maintenance fixture.
[0008] This utility model is achieved using the following technical solution: a server board simulation test and maintenance fixture, including a support column, an operating table fixedly installed at the top of the support column, a circuit board limiting mechanism installed above the operating table, a receiving plate fixedly connected to the outer side of the top of the support column, and a test component installed above the receiving plate.
[0009] The circuit board limiting mechanism includes a connecting platform, which is fixedly connected to the operating platform by a rod. The surface of the connecting platform has a sliding groove, and an upper slider is slidably engaged on the inner surface of the sliding groove. A lower slider is fixedly connected to the bottom end of the upper slider. A cylinder and a return spring are fixedly installed above the upper slider. A limiting plate is fixedly connected to the top of the cylinder, and a clamping block is fixedly connected to the lower front end of the limiting plate. A circuit board is placed on top of the connecting platform.
[0010] The testing assembly includes a fixed plate with a movable groove on its surface. A movable seat is slidably engaged with the surface of the movable groove. A guide rail is provided on the inner wall of the movable groove, and a groove on the bottom of the movable seat slides with the guide rail. A movable rod is fixedly connected above the movable seat, and a movable frame is fitted onto the surface of the movable rod. The movable frame and the movable rod are fixed together by locking bolts. One end of a receiving rod is fixedly connected to the outer side of the movable frame, and the other end of the receiving rod is rotatably connected to a receiving seat. A fixed frame is fixedly connected to the bottom of the receiving seat, and one end of a storage rope is connected to the outer side of the fixed frame. The other end of the storage rope is connected to a test head. A damping bearing is provided at the rotatable connection between the receiving seat and the receiving rod to maintain the positioning angle of the test head.
[0011] As a further optimization of this utility model, this fixture supports the operating table with support columns, and a circuit board limiting mechanism is set above the operating table to fix the circuit board. At the same time, the test components are installed through the receiving plate on the outside of the support columns, realizing precise docking and maintenance operations of the test points on the circuit board. The various structures of the fixture solve the problems of insufficient circuit board fixing flexibility and inconvenient adjustment of test components in the prior art through mechanical linkage and adjustment design.
[0012] As a further optimization of this utility model, two sets of limiting plates and clamping blocks are provided and installed symmetrically. The clamping blocks are made of rubber, and the two sets of clamping blocks clamp and position the circuit board.
[0013] As a further optimization of this utility model, the upper and lower sliders form a U-shaped groove, and the upper and lower sliders slide and engage inside the groove. The connecting platform is fixed to the operating table by a rod, and the upper and lower sliders slide and engage inside the groove on its surface, forming a U-shaped groove, which can slide laterally along the groove. By manually pushing the upper slider, the lower slider moves within the groove, thereby adjusting the relative position of the two sets of limiting plates to accommodate circuit boards of different sizes.
[0014] As a further optimization of this utility model, after the cylinder above the upper slider is activated, it pushes the limiting plate downward, causing the symmetrically arranged rubber clamping blocks to fit against the edge of the circuit board, achieving clamping and positioning. A return spring is sleeved on the outside of the cylinder; when the cylinder retracts, the return spring provides an upward elastic force, causing the limiting plate and clamping blocks to reset, releasing the circuit board. The rubber material of the clamping blocks prevents damage to the circuit board during clamping, while providing sufficient friction to prevent displacement.
[0015] As a further optimization of this utility model, a movable groove is formed on the surface of the fixed plate of the test component, and the guide rail on the inner wall of the movable groove slides in cooperation with the groove at the bottom of the movable seat, so that the movable seat can move laterally along the movable groove to cover the lateral test area of the circuit board.
[0016] As a further optimization of this utility model, the moving rod above the moving base is vertically set, and the moving frame is sleeved on the moving rod. The height of the moving frame can be adjusted up and down by loosening the locking bolt. After adjusting to a suitable position, the bolt is tightened to fix it, so as to realize the vertical positioning of the test head.
[0017] As a further optimization of this utility model, the other end of the receiving rod on the outer side of the movable frame is rotatably connected to the receiving seat via a damping bearing. The angle of the receiving seat can be manually adjusted, and the damping bearing provides resistance to maintain angle stability and prevent the test head from shaking. The fixed frame rotates synchronously with the receiving seat, driving the test head to align with test points at different angles on the circuit board.
[0018] As a further optimization of this utility model, a storage box is provided at the bottom of the fixing frame, and the other end of the storage rope is wound and stored in the storage box. One end of the storage rope is connected to the fixing frame, and the other end suspends the test head. Through the above three-dimensional adjustment, the test head is moved above the target test point on the circuit board, and the test head is manually pressed lightly to make it contact the test point, thus completing the electrical connection and testing.
[0019] As a further optimization of this utility model, the test head can be retracted by a storage rope, with the other end of the storage rope wound and stored in the storage box at the bottom of the fixed frame, to prevent the test head from being placed randomly and causing cable damage, while keeping the surface of the operating table clean.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. This utility model uses a sliding groove and slider design for a circuit board limiting mechanism, which allows manual adjustment of the lateral position of the upper and lower sliders within the sliding groove to accommodate circuit boards of different sizes. Combined with a cylinder-driven rubber clamping block, it achieves symmetrical clamping and positioning, which not only prevents circuit board deformation but also protects circuit components through the buffer material of the rubber material. This solves the problems of insufficient flexibility and uneven pressure in traditional tooling fixing structures, and improves fixing accuracy and applicability.
[0022] 2. The test assembly of this utility model adopts a three-dimensional adjustment structure of a moving groove, a moving rod, and a damping bearing. The moving seat can slide laterally along the moving groove, and the moving frame can be vertically adjusted by locking bolts. The damping rotation connection between the receiving seat and the receiving rod can adjust the angle of the test head, so that the test head can accurately cover any test point on the circuit board without repeatedly disassembling and assembling the circuit board. Compared with the test head of the prior art that can be adjusted in a single direction, it significantly improves the testing efficiency and ease of operation.
[0023] 3. The test head of this utility model is connected to the storage box at the bottom of the fixed frame via a storage rope. After the test is completed, the storage rope can be wound up and stored in the box to avoid cable damage caused by random placement of the test head, while keeping the surface of the operating table clean. The flexible connection of the storage rope also provides a certain range of motion during the test, taking into account both positioning accuracy and operational flexibility, and solving the problem of messy storage of existing tooling test heads.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0031] Example 1:
[0032] Please combine Figures 1-4 This embodiment proposes a server board simulation test and maintenance fixture, including a support column 1, an operating table 2 fixedly installed at the top of the support column 1, a circuit board limiting mechanism 3 installed above the operating table 2, a receiving plate 4 fixedly connected to the outer side of the top of the support column 1, and a test component 5 installed above the receiving plate 4.
[0033] Specifically, this fixture supports the operating table 2 via a support column 1. A circuit board limiting mechanism 3 is installed above the operating table 2 to fix the circuit board 38. Simultaneously, a test component 5 is installed via a receiving plate 4 on the outside of the support column 1, enabling precise connection and maintenance of the test points on the circuit board 38. Through mechanical linkage and adjustment design, the various structures of the fixture solve the problems of insufficient flexibility in fixing the circuit board and inconvenient adjustment of the test component in existing technologies.
[0034] The circuit board limiting mechanism 3 includes a connecting platform 31, which is fixedly connected to the operating platform 2 by a rod. The surface of the connecting platform 31 is provided with a sliding groove 32. An upper slider 33 is slidably engaged on the inner surface of the sliding groove 32. A lower slider 331 is fixedly connected to the bottom end of the upper slider 33. A cylinder 34 and a reset spring 35 are fixedly installed above the upper slider 33. A limiting plate 36 is fixedly connected to the top of the cylinder 34. A clamping block 37 is fixedly connected to the lower front end of the limiting plate 36. A circuit board 38 is placed on top of the connecting platform 31.
[0035] Specifically, in this technical solution, after the cylinder 34 above the upper slider 33 is activated, it pushes the limiting plate 36 downward, causing the symmetrically arranged rubber clamping blocks 37 to fit against the edge of the circuit board 38, achieving clamping and positioning. A return spring 35 is sleeved on the outside of the cylinder 34. When the cylinder 34 retracts, the return spring 35 provides an upward elastic force, causing the limiting plate 36 and clamping blocks 37 to reset, releasing the circuit board 38. The rubber material of the clamping blocks 37 prevents damage to the circuit board 38 during clamping, while providing sufficient friction to prevent displacement.
[0036] It should be noted that the upper slider 33 and the lower slider 331 form a U-shaped groove, and the upper slider 33 and the lower slider 331 slide inside the slide groove 32. The connecting platform 31 is fixed to the operating platform 2 by a rod, and the upper slider 33 and the lower slider 331 slide inside the slide groove 32 on its surface, forming a U-shaped groove, which can slide laterally along the slide groove 32. By manually pushing the upper slider 33, the lower slider 331 is moved within the slide groove 32, thereby adjusting the relative position of the two sets of limiting plates 36 to adapt to circuit boards 38 of different sizes.
[0037] Furthermore, two sets of limiting plates 36 and clamping blocks 37 are provided and installed symmetrically. The clamping blocks 37 are made of rubber, and the two sets of clamping blocks 37 clamp and position the circuit board 38.
[0038] Test assembly 5 includes a fixed plate 51, with a movable groove 52 on its surface. A movable seat 53 is slidably engaged with the surface of the movable groove 52. A guide rail is provided on the inner wall of the movable groove 52. The bottom of the movable seat 53 has a groove that slides with the guide rail. A movable rod 54 is fixedly connected to the top of the movable seat 53. A movable frame 55 is sleeved on the surface of the movable rod 54. The movable frame 55 and the movable rod 54 are fixed together by locking bolts 56. One end of a receiving rod 57 is fixedly connected to the outside of the movable frame 55. The other end of the receiving rod 57 is rotatably connected to a receiving seat 58. A fixed frame 59 is fixedly connected to the bottom of the receiving seat 58. One end of a storage rope 510 is connected to the outside of the fixed frame 59. The other end of the storage rope 510 is connected to a test head 511.
[0039] A damping bearing is provided at the rotatable connection between the receiving seat 58 and the receiving rod 57. The damping bearing is used to maintain the positioning angle of the test head 511.
[0040] Specific technical solutions:
[0041] Horizontal movement:
[0042] The surface of the fixed plate 51 of the test component 5 has a moving groove 52. The guide rail on the inner wall of the moving groove 52 slides and engages with the groove at the bottom of the moving seat 53, so that the moving seat 53 can move laterally along the moving groove 52 to cover the lateral test area of the circuit board 38.
[0043] Vertical adjustment
[0044] The moving rod 54 above the moving base 53 is vertically set, and the moving frame 55 is sleeved on the moving rod 54. The height of the moving frame 55 can be adjusted up and down by loosening the locking bolt 56. After adjusting to the appropriate position, the bolt is tightened to fix it, so as to achieve the vertical positioning of the test head 511.
[0045] Angle and direction adjustment
[0046] The other end of the receiving rod 57 on the outer side of the movable frame 55 is rotatably connected to the receiving seat 58 via a damping bearing, allowing manual adjustment of the angle of the receiving seat 58. The damping bearing provides resistance to maintain angle stability and prevent the test head 511 from shaking. The fixed frame 59 rotates synchronously with the receiving seat 58, driving the test head 511 to align with test points at different angles on the circuit board 38.
[0047] It should be noted that the bottom of the mounting bracket 59 is equipped with a storage box, and the other end of the storage rope 510 is wound and stored in the storage box.
[0048] A further technical solution involves connecting one end of the storage rope 510 to the fixing frame 59 and suspending the test head 511 at the other end. Through the aforementioned three-dimensional adjustment, the test head 511 is moved above the target test point on the circuit board 38. The test head 511 is then manually pressed lightly to make it contact the test point, thus completing the electrical connection and testing.
[0049] After the test is completed, the test head 511 can be retracted by the storage rope 510. The other end of the storage rope 510 is wound and stored in the storage box at the bottom of the fixing frame 59 to prevent the test head 511 from being placed randomly and causing cable damage, while keeping the surface of the operating table 2 clean.
[0050] The working principle of a server board simulation testing and maintenance fixture:
[0051] I. Overview of Overall Structural Work
[0052] This fixture supports the operating table 2 via support column 1. A circuit board limiting mechanism 3 is installed above the operating table 2 to fix the circuit board 38. At the same time, the test assembly 5 is installed on the receiving plate 4 on the outside of the support column 1, so as to achieve precise docking and maintenance of the test points of the circuit board 38. The various structures of the fixture are designed with mechanical linkage and adjustment to solve the problems of insufficient flexibility in fixing the circuit board and inconvenience in adjusting the test assembly in the existing technology.
[0053] II. Working Principle of Circuit Board Limiting Mechanism
[0054] The connecting platform 31 is fixed to the operating platform 2 by a rod. The upper slider 33 and the lower slider 331 are slidably engaged in the sliding groove 32 on its surface, forming a U-shaped groove that can slide laterally along the sliding groove 32. By manually pushing the upper slider 33, the lower slider 331 is moved within the sliding groove 32, thereby adjusting the relative position of the two sets of limiting plates 36 to accommodate circuit boards 38 of different sizes.
[0055] After the cylinder 34 above the upper slider 33 is activated, it pushes the limiting plate 36 downward, causing the symmetrically arranged rubber clamping blocks 37 to fit against the edge of the circuit board 38, achieving clamping and positioning. A return spring 35 is sleeved on the outside of the cylinder 34. When the cylinder 34 retracts, the return spring 35 provides an upward elastic force, causing the limiting plate 36 and clamping blocks 37 to reset, releasing the circuit board 38. The rubber material of the clamping blocks 37 prevents damage to the circuit board 38 during clamping, while providing sufficient friction to prevent displacement.
[0056] III. Three-dimensional adjustment principle of the test components
[0057] Horizontal movement:
[0058] The surface of the fixed plate 51 of the test component 5 has a moving groove 52. The guide rail on the inner wall of the moving groove 52 slides and engages with the groove at the bottom of the moving seat 53, so that the moving seat 53 can move laterally along the moving groove 52 to cover the lateral test area of the circuit board 38.
[0059] Vertical adjustment:
[0060] The moving rod 54 above the moving base 53 is vertically set, and the moving frame 55 is sleeved on the moving rod 54. The height of the moving frame 55 can be adjusted up and down by loosening the locking bolt 56. After adjusting to the appropriate position, the bolt is tightened to fix it, so as to achieve the vertical positioning of the test head 511.
[0061] Angle and direction adjustment:
[0062] The other end of the receiving rod 57 on the outer side of the movable frame 55 is rotatably connected to the receiving seat 58 via a damping bearing, allowing manual adjustment of the angle of the receiving seat 58. The damping bearing provides resistance to maintain angle stability and prevent the test head 511 from shaking. The fixed frame 59 rotates synchronously with the receiving seat 58, driving the test head 511 to align with test points at different angles on the circuit board 38.
[0063] One end of the storage rope 510 is connected to the fixing frame 59, and the other end suspends the test head 511. Through the above three-dimensional adjustment, the test head 511 is moved above the target test point on the circuit board 38. The test head 511 is manually pressed lightly to make it contact the test point, thus completing the electrical connection and testing.
[0064] After the test is completed, the test head 511 can be retracted by the storage rope 510. The other end of the storage rope 510 is wound and stored in the storage box at the bottom of the fixing frame 59 to prevent the test head 511 from being placed randomly and causing cable damage, while keeping the surface of the operating table 2 clean.
[0065] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
