Description

Technical Field

[0001] This utility model relates to the field of electronic equipment testing technology, and in particular to a positioning fixture for testing the contact of gold fingers on used hard drives. Background Technology

[0002] With the rapid development of information technology, the pace of electronic device upgrades is accelerating, and the recycling and reuse of second-hand electronic devices has become an important industry. In the process of testing and repairing second-hand electronic devices, the hard drive, as a core storage component, is crucial for performance testing. The gold fingers of the hard drive are the key part connecting the hard drive to external devices, and the quality of their contact directly affects the read and write performance and stability of the hard drive. Therefore, accurate and efficient testing of the contact of the gold fingers of second-hand hard drives is an important step in ensuring the quality of the hard drive.

[0003] Traditional hard drive testing positioning fixtures typically use screws to fix the clamping plate onto the fixture. While this method is simple in structure, it presents several problems in actual operation. First, screw fixing requires tools for disassembly and assembly, which is cumbersome and time-consuming. Each time the hard drive is replaced or the clamping plate is adjusted, the screws need to be loosened or tightened one by one. This not only increases the workload of the operator but also easily leads to stripped or damaged screws due to improper operation, further affecting the normal use of the fixture. Second, screw fixing is prone to loosening or insecure fixing when the hard drive is frequently replaced or the clamping plate is adjusted, causing the hard drive to shift or have poor contact during testing, affecting the accuracy and reliability of the test results. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a positioning fixture for testing the contact of gold fingers on used hard drives.

[0005] This utility model is achieved using the following technical solution: a positioning fixture for testing the contact properties of gold fingers on a used hard drive, comprising a base plate, a protective shell fixedly connected to the upper surface of the base plate, a drive motor fixedly connected to the inner wall of the protective shell, a bidirectional lead screw fixedly connected to the output end of the drive motor, mounting sleeves threaded to both ends of the bidirectional lead screw, a locking seat fixedly connected to the surface of the mounting sleeve, an embedding groove formed on the surface of the locking seat, a mounting block fixedly mounted on the locking seat via a snap-fit ​​mechanism, a clamping plate fixedly connected to the surface of the mounting block, and a rubber pad provided on the surface of the clamping plate.

[0006] The above technical solution effectively clamps and fixes the hard drive through the synergistic action of the drive motor, bidirectional lead screw, mounting sleeve, locking seat, clamping plate, and rubber pad. The rubber pad prevents the hard drive from being excessively squeezed and damaged during clamping, ensuring the hard drive remains stable throughout the test and guaranteeing the accuracy of the test results. The snap-fit ​​mechanism allows for quick disassembly and assembly of the locking seat, mounting block, and clamping plate, facilitating easy replacement and installation of hard drives of different sizes according to actual positioning needs. This greatly expands the applicability of the fixture, enabling it to meet the testing requirements of various hard drive models.

[0007] As a further improvement to the above solution, the snap-fit ​​mechanism includes an auxiliary frame, a lifting plate is slidably connected inside the auxiliary frame, a telescopic rod is fixedly connected to the upper surface of the lifting plate, a transmission screw is threaded to the top end of the telescopic rod, a knob is fixedly connected to the top end of the transmission screw, and a limit rod is fixedly connected to the lower surface of the lifting plate.

[0008] The above technical solution enables rapid assembly and disassembly of the clamping plate, greatly improving the efficiency of clamping plate replacement, saving operators' time and effort, and enabling the fixture to quickly adjust when facing different hard drive sizes that require clamping plate replacement, thereby improving the continuity and efficiency of testing work.

[0009] As a further improvement to the above solution, the surface of the mounting block is provided with positioning holes, the positioning holes and the limiting rods are adapted to each other, and the embedding groove and the mounting block are adapted to each other.

[0010] As a further improvement to the above solution, the auxiliary frame is fixedly connected to the upper surface of the locking seat, and the surface of the locking seat is provided with an active cavity that is compatible with the limiting rod.

[0011] As a further improvement to the above solution, a limiting groove is provided on the inner wall of the auxiliary frame, and the surface of the lifting plate is slidably connected to the inside of the limiting groove by a slider.

[0012] Through the above technical solution, the cooperation between the limiting slide and the slider effectively limits and guides the movement of the lifting plate, making the lifting plate more stable and accurate during the lifting process. This avoids problems such as the limit rod not being firmly connected to the mounting block or the failure of the locking due to the unstable movement of the lifting plate, and improves the movement stability and reliability of the locking mechanism.

[0013] As a further improvement to the above solution, a control panel is provided on the upper surface of the protective shell, and the control panel is electrically connected to the drive motor. Pre-set holes and slots are provided at the four corners of the substrate surface.

[0014] As a further improvement to the above solution, a limiting slide rail is provided on the surface of the protective shell, and the mounting screw sleeve is slidably connected to the inside of the limiting slide rail.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses a drive motor to rotate a bidirectional lead screw, which in turn moves the mounting sleeve and locking seat, thereby clamping and fixing the hard drive with a clamping plate. Operation is simple and quick. Simultaneously, by rotating a knob, the operator moves the transmission screw, which in turn moves the telescopic rod and lifting plate, causing the limit rod to rise and disengage from or descend and insert into the mounting block, enabling rapid assembly and disassembly of the clamping plate. This effectively avoids the cumbersome steps and potential screw stripping problems associated with traditional screw-based fixing methods, significantly saving time when replacing hard drives or adjusting the clamping plate, and improving work efficiency. Its advantages are particularly evident when testing a large number of hard drives or frequently changing hard drive sizes and specifications, significantly enhancing the ease of use and flexibility of the fixture.

[0023] The present invention will be further described below with reference to 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.

[0024] Example:

[0025] Please combine Figure 1-4The positioning fixture for testing the contact properties of the gold fingers of a used hard drive in this embodiment includes a base plate 1. A protective shell 2 is fixedly connected to the upper surface of the base plate 1. A drive motor 3 is fixedly connected to the inner wall of the protective shell 2. A bidirectional lead screw 4 is fixedly connected to the output end of the drive motor 3. Both ends of the bidirectional lead screw 4 are threadedly connected to mounting sleeves 5. A locking seat 6 is fixedly connected to the surface of the mounting sleeve 5. An embedding groove 7 is opened on the surface of the locking seat 6. An mounting block 8 is fixedly mounted on the locking seat 6 through a snap-fit ​​mechanism. A clamping plate 9 is fixedly connected to the surface of the mounting block 8. A rubber pad 10 is provided on the surface of the clamping plate 9. When the operator starts the drive motor 3, the drive motor 3 drives the bidirectional lead screw 4. Rotation, under the action of the limiting component, causes the rotation of the bidirectional lead screw 4 to make the mounting sleeves 5 on both sides move linearly. If the two mounting sleeves 5 move towards the center synchronously, they will drive the locking seats 6 on both sides to move towards the center synchronously, thereby causing the clamping plate 9 and rubber pad 10 engaged by the locking seat 6 to move, thus clamping the hard drive. During the clamping process, the rubber pad 10 on the surface of the clamping plate 9 can avoid excessive compression of the hard drive, ensuring that the hard drive remains stable when it is fixed. At the same time, the clamping mechanism can quickly realize the disassembly and assembly of the locking seat 6, the mounting block 8 and the clamping plate 9, which makes it easy for personnel to quickly replace and install hard drives of different sizes according to actual positioning needs, improving the applicability of the fixture.

[0026] The clamping mechanism includes an auxiliary frame 11, with a lifting plate 12 slidably connected inside the auxiliary frame 11. A telescopic rod 13 is fixedly connected to the upper surface of the lifting plate 12, and a transmission screw 14 is threadedly connected to the top of the telescopic rod 13. A knob 15 is fixedly connected to the top of the transmission screw 14, and a limit rod 16 is fixedly connected to the lower surface of the lifting plate 12. When it is necessary to disassemble the clamping plate 9, the operator rotates the knob 15, causing the transmission screw 14 to rotate. The rotation of the transmission screw 14 drives the telescopic rod 13 to move, and the telescopic rod 13 in turn drives the lifting plate 12 to move linearly up and down along the inner wall of the auxiliary frame 11. When the lifting plate 12 rises, the limiting rod 16 on its lower surface rises accordingly, thus disengaging from the interior of the mounting block 8. At this time, the operator can remove the mounting block 8 from the interior of the locking seat 6. When the clamping plate 9 needs to be installed, the operator only needs to insert the mounting block 8 into the embedding groove 7 inside the locking seat 6, and then rotate the knob 15 in the opposite direction. The transmission screw 14 drives the telescopic rod 13 and the lifting plate 12 to descend, causing the limiting rod 16 to descend and insert into the interior of the mounting block 8, thereby fixing the mounting block 8 and the clamping plate 9 inside the locking seat 6, completing the quick installation of the clamping plate 9.

[0027] The surface of the mounting block 8 is provided with a positioning hole 17, which is adapted to the limiting rod 16. The embedding groove 7 is adapted to the mounting block 8, so that the limiting rod 16 can be accurately inserted into the positioning hole 17 of the mounting block 8, and the mounting block 8 can be accurately embedded into the embedding groove 7 of the locking seat 6, thereby achieving a tight fit and stable connection between the mounting block 8 and the locking seat 6.

[0028] The auxiliary frame 11 is fixedly connected to the upper surface of the locking seat 6, and the surface of the locking seat 6 is provided with a movable cavity that is compatible with the limiting rod 16.

[0029] The inner wall of the auxiliary frame 11 is provided with a limiting groove 18. The surface of the lifting plate 12 is slidably connected to the inside of the limiting groove 18 by a slider. The lifting plate 12 moves linearly up and down along the limiting groove 18 on the inner wall of the auxiliary frame 11. The limiting groove 18 plays a good role in limiting and guiding the movement of the lifting plate 12, ensuring that the lifting plate 12 always maintains a stable and accurate movement trajectory during the lifting process, thereby driving the limiting rod 16 to perform a smooth lifting action, realizing the quick installation and disassembly of the clamping plate 9.

[0030] The upper surface of the protective shell 2 is provided with a control panel 19, which is electrically connected to the drive motor 3. Pre-set holes and slots 20 are provided at the four corners of the surface of the substrate 1.

[0031] A limiting slide rail is provided on the surface of the protective shell 2, and the mounting sleeve 5 is slidably connected to the inside of the limiting slide rail.

[0032] The implementation principle of the used hard drive gold finger contact test positioning fixture in this application embodiment is as follows: First, in the used hard drive gold finger contact test positioning fixture, when the operator starts the drive motor 3, the output end of the drive motor 3 drives the bidirectional lead screw 4 to rotate. Under the action of the limiting component, the rotation of the bidirectional lead screw 4 causes the mounting sleeves 5 on both sides to move linearly. If the two mounting sleeves 5 move towards the center synchronously, they will also drive the locking seats 6 on both sides to move towards the center synchronously. Since the locking seat 6 is fixedly installed with the mounting block 8 through the snap-fit ​​mechanism, and the mounting block 8 is connected to the clamping plate 9, and the surface of the clamping plate 9 is also provided with a rubber pad 10, the movement of the locking seat 6 will drive the clamping plate 9 and the rubber pad 10 to move synchronously, thereby realizing the clamping of the hard drive. During the clamping process, the rubber pad 10 on the surface of the clamping plate 9 can effectively avoid excessive compression of the hard drive and ensure that the hard drive remains stable when it is fixed.

[0033] When it is necessary to disassemble the clamping plate 9, the operator rotates the knob 15 to rotate the transmission screw 14. The rotation of the transmission screw 14 drives the telescopic rod 13 to move, which in turn drives the lifting plate 12 to move linearly up and down along the inner wall of the auxiliary frame 11. When the lifting plate 12 rises, the limiting rod 16 on its lower surface rises accordingly, thus disengaging from the interior of the mounting block 8. At this time, the operator can remove the mounting block 8 from the interior of the locking seat 6. When it is necessary to install the clamping plate 9, the operator only needs to insert the mounting block 8 into the embedding groove 7 inside the locking seat 6, and then rotate the knob 15 in the opposite direction. The transmission screw 14 drives the telescopic rod 13 and the lifting plate 12 to descend, causing the limiting rod 16 to descend and insert into the mounting block 8. The mounting block 8 and clamping plate 9 are fixed inside the locking seat 6, thus completing the quick installation of the clamping plate 9. This allows the limiting rod 16 to be accurately inserted into the positioning hole 17 of the mounting block 8, and the mounting block 8 to be accurately embedded in the embedding groove 7 of the locking seat 6. This achieves a tight fit and stable connection between the mounting block 8 and the locking seat 6. The lifting plate 12 moves linearly up and down along the limiting slide groove 18 on the inner wall of the auxiliary frame 11. The limiting slide groove 18 plays a good role in limiting and guiding the movement of the lifting plate 12, ensuring that the lifting plate 12 always maintains a stable and accurate movement trajectory during the lifting process. This drives the limiting rod 16 to perform a smooth lifting action, realizing the quick installation and removal of the clamping plate 9.

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.
