Description

Technical Field

[0001] This utility model relates to the field of server manufacturing technology, specifically to a chassis positioning mechanism. Background Technology

[0002] Server chassis are a crucial component of servers, serving as a dedicated enclosure for mounting and protecting server hardware components. Typically made of metal, they feature a robust structure and excellent heat dissipation. Chassis manufacturing is critical in server production, and to improve processing efficiency, a chassis positioning mechanism is needed. However, current chassis positioning mechanisms still suffer from the following shortcomings:

[0003] For example, patent document CN220259355U discloses a positioning device for punching holes in a computer chassis. This positioning device lifts the chassis using a lifting assembly and activates a first motor to rotate a rotating column. The rotating column then rotates the clamping plate and the clamped chassis, thus flipping the chassis. This eliminates the need to release the chassis's fixation or manually flip it, making it more convenient and labor-saving. However, it is not conducive to stable and accurate positioning of the chassis, which can easily affect the processing quality during actual processing.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed a chassis positioning mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a chassis positioning mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chassis positioning mechanism, comprising a support base and a positioning component. Support frames are installed at both the front and rear ends of the upper side of the support base, and support crossbars are provided at the upper and lower ends of the inner side of the support frames. A support plate is installed on the surface of the support crossbars. The positioning component is disposed on the surface of the support plate and includes a front-mounted cylinder, a motor frame, a movable guide rail, a fixed plate, a micro motor, a threaded screw, a movable component, a front-mounted block, and a limiting rod. The front-mounted cylinder is disposed on the upper surface of the support plate, and a motor frame is installed at the outer end of the front-mounted cylinder. A movable guide rail is provided at the rear side of the motor frame, and the movable guide rail and the motor frame are a tightly connected integrated structure. A fixed plate is installed at the rear side of the movable guide rail.

[0007] Furthermore, a micro motor is installed on the rear surface inside the motor frame, and the output end of the micro motor is connected to a threaded screw via a coupling. The rear end of the threaded screw passes through the rear side of the motor frame and is connected to the front side of the fixing plate.

[0008] Furthermore, the outer surface of the threaded screw is threaded with a movable part, and the outer surface of the movable part is slidably connected to the inner side of the movable guide rail. A front top block is installed on the surface of the movable part.

[0009] Furthermore, a limit rod is installed on the inner side of the rear end of the movable guide rail, and the surface of the limit rod is slidably connected to the inside of the support plate.

[0010] Furthermore, the surface of the support plate is provided with a limiting component for limiting the position, and the limiting component includes a movable electric cylinder, a pressure sensor and a connecting plate. The movable electric cylinder is located at the lower end of the surface of the support plate, and a pressure sensor is installed at the outer end of the movable electric cylinder. A connecting plate is provided on the outer side of the pressure sensor.

[0011] Furthermore, the limiting component also includes a limiting plate and a limiting crossbar, and the limiting plate is installed on the surface of the connecting plate. The limiting plate is provided with limiting crossbars on both ends of the limiting plate, and the limiting crossbars are slidably connected to the inside of the support plate.

[0012] Furthermore, a guide plate is installed on the side surface of the support base, and a non-powered roller is provided at the lower end of the guide plate surface. Three sets of non-powered rollers are arranged at equal intervals.

[0013] Furthermore, a support beam is installed on the upper inner side of the support frame, and a hoisting limit block is installed on the lower side of the support beam. The support base is symmetrically arranged at both ends of the support beam, and there are two sets of support bases.

[0014] This utility model provides a chassis positioning mechanism, which has the following beneficial effects:

[0015] 1. This utility model incorporates a positioning component, which includes a front-mounted cylinder, a motor frame, a movable guide rail, a fixed plate, a micro motor, a threaded screw, a movable component, a front-mounted block, and a limiting rod. In use, activating the front-mounted cylinder causes the two sets of motor frames and the movable guide rail to move towards each other, thereby moving the front-mounted block to a suitable position to accommodate the dimensions of the machine chassis being processed. Activating the micro motor causes the threaded screw to rotate, which in turn drives the movable component to move along the inner side of the movable guide rail. The movable guide rail then moves the front-mounted block forward, thus positioning the machine chassis. The limiting rod, through its sliding connection with the support plate, limits the movement of the motor frame and the movable guide rail, enabling the device to accurately position the processing location of the machine chassis being processed.

[0016] 2. This utility model incorporates a limiting component, which includes a movable electric cylinder, a pressure sensor, and a connecting plate. The limiting component also includes a limiting plate and a limiting crossbar. In use, activating the movable electric cylinder causes it to move two sets of connecting plates towards each other via the pressure sensor. This, in turn, causes the limiting plates to move towards each other via the connecting plates. The limiting plates provide stable positioning of the machine casing. The sliding connection between the limiting crossbar and the support plate further limits the movement of the connecting plates. The pressure sensor can detect the pressure exerted by the movable electric cylinder on the connecting plates in real time, preventing excessive pressure that could damage the machine casing. Therefore, this device can provide appropriate and stable positioning of the machine casing, preventing displacement of the machine casing during processing. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4As shown, a chassis positioning mechanism includes a support base 1 and a positioning component 5. Support frames 2 are mounted on the front and rear ends of the upper side of the support base 1, and support crossbars 3 are provided at the upper and lower ends of the inner side of the support frames 2. A support plate 4 is mounted on the surface of the support crossbars 3. The positioning component 5 is disposed on the surface of the support plate 4 and includes a front-mounted cylinder 501, a motor frame 502, a movable guide rail 503, a fixed plate 504, a micro motor 505, a threaded screw 506, a movable component 507, a front-mounted block 508, and a limiting rod 509. The front-mounted cylinder 501 is disposed on the upper surface of the support plate 4, and the motor frame 502 is mounted on the outer end of the front-mounted cylinder 501. A movable guide rail 503 is provided on the rear side of the motor frame 502, and the movable guide rail 503 is provided on the rear side of the motor frame 502. The guide rail 503 and the motor frame 502 are a tightly connected integrated structure. A fixing plate 504 is installed on the rear side of the movable guide rail 503. A micro motor 505 is installed on the rear surface inside the motor frame 502. The output end of the micro motor 505 is connected to a threaded screw 506 through a coupling. The rear end of the threaded screw 506 passes through the rear side of the motor frame 502 and is connected to the front side of the fixing plate 504. A movable part 507 is threadedly connected to the outer surface of the threaded screw 506. The outer surface of the movable part 507 is slidably connected to the inner side of the movable guide rail 503. A front top block 508 is installed on the surface of the movable part 507. A limit rod 509 is installed on the inner side of the rear end of the movable guide rail 503. The surface of the limit rod 509 is slidably connected to the inside of the support plate 4.

[0024] The specific operation is as follows: When in use, start the front push cylinder 501, which drives the two sets of motor frames 502 and the movable guide rail 503 to move towards each other, thereby moving the front push block 508 to a suitable position to adapt to the size of the machine box to be processed. Start the micro motor 505, which drives the threaded screw 506 to rotate. The threaded screw 506 drives the movable part 507 to move along the inner side of the movable guide rail 503. The movable guide rail 503 drives the front push block 508 to move forward, positioning the machine box. The limit rod 509 is slidably connected to the support plate 4, which plays a certain role in limiting the movement of the motor frame 502 and the movable guide rail 503.

[0025] Please refer to Figures 3 to 4The support plate 4 is provided with a limiting component 6 for limiting the position. The limiting component 6 includes a movable electric cylinder 601, a pressure sensor 602 and a connecting plate 603. The movable electric cylinder 601 is located at the lower end of the support plate 4, and the pressure sensor 602 is installed at the outer end of the movable electric cylinder 601. The connecting plate 603 is provided on the outer side of the pressure sensor 602. The limiting component 6 also includes a limiting plate 604 and a limiting crossbar 605. The limiting plate 604 is installed on the surface of the connecting plate 603. The limiting crossbar 605 is provided on both ends of the limiting plate 604 and is slidably connected to the inside of the support plate 4. The side surface of the support base 1 is provided with a guide plate 7, and the lower end of the guide plate 7 is provided with a non-powered roller 8. Three sets of non-powered rollers 8 are equidistantly arranged. The upper inner side of the support frame 2 is provided with a support beam 9, and the lower side of the support beam 9 is provided with a hoisting limiting block 10. The support base 1 is symmetrically arranged at both ends of the support beam 9 and has two sets.

[0026] The specific operation is as follows: During use, the chassis is mounted on the non-powered roller 8. With the assistance of the non-powered roller 8, the chassis can be moved easily for loading and unloading. The guide plate 7 guides the loading and unloading of the chassis. The lifting limit block 10 limits the rear side of the chassis. The movable electric cylinder 601 is activated, which drives the two sets of connecting plates 603 to move towards each other through the pressure sensor 602. In turn, the connecting plates 603 drive the limit plate 604 to move towards each other. The limit plate 604 provides stable limitation for the chassis. The sliding connection between the limit crossbar 605 and the support plate 4 limits the movement of the connecting plate 603. The pressure sensor 602 can detect the pressure of the movable electric cylinder 601 on the limiting of the connecting plate 603 in real time to prevent excessive compression from damaging the chassis.

[0027] In summary, as Figures 1 to 4As shown, in use, the chassis positioning mechanism first places the chassis on the unpowered roller 8. With the assistance of the unpowered roller 8, the chassis can be easily moved for loading and unloading. The guide plate 7 guides the loading and unloading of the chassis. The lifting limit block 10 limits the rear of the chassis. Activating the movable electric cylinder 601 causes it to drive two sets of connecting plates 603 to move towards each other via the pressure sensor 602. This, in turn, causes the connecting plates 603 to drive the limit plates 604 to move towards each other, thus providing stable positioning of the chassis. The sliding connection between the limit crossbar 605 and the support plate 4 further limits the movement of the connecting plates 603. The pressure sensor 602 monitors the movement of the movable electric cylinder 601 and the connecting plates... The pressure of the 603 limit switch is monitored in real time to prevent excessive compression from damaging the chassis. Then, the front push cylinder 501 is activated, which drives the two sets of motor frames 502 and the movable guide rail 503 to move towards each other, thereby moving the front push block 508 to a suitable position to adapt to the chassis size being processed. The micro motor 505 is activated, which drives the threaded screw 506 to rotate. The threaded screw 506 drives the movable part 507 to move along the inner side of the movable guide rail 503. The movable guide rail 503 drives the front push block 508 to move forward, positioning the chassis. The limit rod 509 is slidably connected to the support plate 4, which limits the movement of the motor frame 502 and the movable guide rail 503.
