Description

Technical Field

[0001] This invention belongs to the field of server impact testing technology, specifically a universal server impact fixing fixture. Background Technology

[0002] Servers possess high-speed CPU processing power, reliable operation over extended periods, robust I / O external data throughput, and superior scalability. Generally, depending on the services provided, servers are capable of responding to service requests, providing services, and ensuring service availability.

[0003] To ensure high reliability of server operation, mechanical shock tests are conducted before the servers leave the factory. On the one hand, this assesses the overall fragility of the machine, providing a basis for packaging design; on the other hand, the overall structure also needs a certain degree of rigidity and strength to ensure the reliability of the server during operation and avoid mechanical damage caused by external stimuli.

[0004] Server impact testing requires clamps to secure the server to an impact test bench. Traditional whole-machine impact testing places the clamping force directly on the server chassis, and the clamping area is limited. During impact testing, this can easily cause additional deformation in the clamped area, leading to quality issues upon shipment. Furthermore, traditional whole-machine impact testing requires a custom-made fixture to match the specific size and shape of the server chassis. After the impact test, this fixture is discarded, cannot be reused, lacks universal compatibility, and has high testing costs and a long production cycle. Summary of the Invention

[0005] To address the problems of traditional server impact testing, which easily causes additional deformation in the server clamping area, resulting in shipment quality issues, and the lack of universal compatibility of the fixing fixtures, making them unusable and resulting in high testing costs and long manufacturing cycles, this invention provides a universal server impact fixing fixture.

[0006] This invention is achieved through the following technical solution:

[0007] A universal server impact fixing fixture includes server positioning sleeves that can be fitted onto the front and rear ends of a server. Server positioning brackets that can support and limit the front and rear windows of the server are installed on the opposite outer sides of the two server positioning sleeves. The fixture also includes several long strip-shaped adjustment brackets connected and installed between the two server positioning sleeves. The adjustment brackets have adjustment channels along their length, and adjustment screws that are screwed onto the two server positioning sleeves are inserted into the adjustment channels.

[0008] A further improvement of the present invention is that two adjustment brackets are respectively provided on the upper and lower sides of the server positioning sleeve, and one adjustment bracket is respectively provided on the left and right sides.

[0009] A further improvement of the present invention is that the server positioning sleeve has an adjustment bracket mounting groove that fits into the adjustment bracket.

[0010] A further improvement of the present invention is that the depth of the adjustment bracket mounting groove is greater than the thickness of the adjustment bracket.

[0011] A further improvement of the present invention is that the server positioning bracket has a U-shaped plate structure, and the server positioning bracket includes an end plate and a connecting plate connected to the upper and lower ends of the end plate; the connecting plate is fitted and positioned to fit the upper and lower sides of the server positioning sleeve.

[0012] A further improvement of the present invention is that the upper and lower sides of the server positioning sleeve are respectively provided with positioning baffle slots that can be used to position the connecting plate.

[0013] A further improvement of the present invention is that the depth of the positioning baffle groove is not less than the thickness of the connecting plate.

[0014] A further improvement of the present invention is that the depth of the positioning baffle groove is equal to the thickness of the connecting plate, and the server positioning baffle is provided with a countersunk positioning mounting hole, in which a positioning screw is screwed to the upper and lower sides of the server positioning sleeve.

[0015] A further improvement of the present invention is that the width of the end plate is greater than the width of the connecting plate, and the width of the end plate is adapted to the width of the server positioning sleeve.

[0016] A further improvement of the present invention is that an end protective layer is provided on the inner side of the end plate.

[0017] As can be seen from the above technical solutions, the beneficial effects of the present invention are:

[0018] Two server positioning sleeves are respectively fitted onto the front and rear ends of the server and connected by a long, adjustable bracket. The front and rear window positions of the server are supported and limited by server positioning stops, forming a closed positioning space for the server. During impact testing, the impact table fixture can directly clamp this fixture, effectively distributing the force of the impact table fixture and avoiding additional deformation caused by direct clamping of the server, thus ensuring product quality. Furthermore, by loosening the adjusting screws and pushing and pulling the two server positioning sleeves, the distance between the two server positioning stops can be flexibly adjusted. This allows for flexible application to impact testing of servers of different lengths, offering good versatility and enabling fixture recycling, thereby saving development and usage costs. The overall structure is simple, easy to use, and highly practical. Attached Figure Description

[0027] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] As shown in the figure, an optional embodiment of the present invention discloses a universal server impact fixing fixture, including two server positioning sleeves 1 that can be fitted onto the front and rear ends of a server 6. Server positioning brackets 2 that can support and limit the front and rear windows of the server 6 are installed on the opposite outer sides of the two server positioning sleeves 1 (i.e., the front side of the front server positioning sleeve 1 and the rear side of the rear server positioning sleeve 1). The universal server impact fixing fixture also includes several elongated adjustment brackets 3 connected and installed between the two server positioning sleeves 1. The adjustment brackets 3 are arranged in a front-back direction. The adjustment brackets 3 have front-back direction adjustment channels 31 along their length direction (front-back direction). Adjustment screws 4 that are screwed and installed into the adjustment channels 31 are respectively screwed onto the two server positioning sleeves 1.

[0029] The server positioning sleeve 1 is shaped to fit the server 6 chassis and has a rectangular cylindrical structure. Two server positioning sleeves 1 are respectively fitted onto the front and rear ends of the server 6 and connected by a long adjustable bracket 3. The front and rear windows of the server 6 are supported and limited by server positioning stops 2, forming a closed positioning space for the server 6. During impact testing, the impact table fixture can directly clamp this fixing fixture (usually clamping the upper and lower sides of the two server positioning sleeves 1). This fixing fixture effectively distributes the force of the impact table fixture, avoiding additional deformation caused by directly clamping the server 6 and ensuring product quality. Furthermore, by loosening the adjusting screw 4 and pushing and pulling the two server positioning sleeves 1 (the adjusting screw 4 slides into the adjusting channel 31), the distance between the two server positioning stops 2 can be flexibly adjusted. This allows for flexible application to impact testing of servers 6 of different lengths, offering good versatility and enabling fixture recycling, thus saving development and usage costs. The overall structure is simple, easy to use, and highly practical.

[0030] Since the server 6 chassis has standard dimensions: standard U height and standard 19-inch width, 1U is 44.45mm, 2U is 88.9mm, and the width is 450mm; for servers of different U sizes, only server positioning sleeves 1 and server positioning brackets 2 of corresponding sizes can be developed for connection and installation. Servers of the same U size use a set of fixing fixtures.

[0031] If the manufacturing size of server 6 is too small, Mylar inserts can be used to fill the gaps. Commonly used Mylar inserts are 0.5mm or 1mm thick.

[0032] Another optional embodiment of the present invention discloses a universal server impact fixing fixture, including two server positioning sleeves 1 that can be fitted onto the front and rear ends of a server 6. Server positioning brackets 2, capable of supporting and limiting the front and rear windows of the server 6, are installed on the opposite outer sides of the two server positioning sleeves 1 (i.e., the front side of the front server positioning sleeve 1 and the rear side of the rear server positioning sleeve 1). This universal server impact fixing fixture also includes several elongated adjusting brackets 3 connected and installed between the two server positioning sleeves 1. The adjusting brackets 3 are arranged in a front-rear direction, and have front-rear adjusting channels 31 along their length (front-rear direction). Adjusting screws 4, respectively screwed onto the adjusting channels 31, are inserted into the adjusting channels 31. Two adjusting brackets 3 are respectively provided on the upper and lower sides of the server positioning sleeves 1, and one adjusting bracket 3 is provided on each of the left and right sides. The adjusting brackets 3 are symmetrically arranged relative to the server 6, ensuring the balance and reliability of the connection between the adjusting brackets 3 and the two server positioning sleeves 1, thus guaranteeing the reliability of the server impact test.

[0033] Specifically, two server positioning sleeves 1 are respectively fitted onto the front and rear ends of the server 6, connected by a long strip-shaped adjusting bracket 3. The front and rear window positions of the server 6 are respectively supported and limited by server positioning stops 2, forming a closed positioning space for the server 6. During impact testing, the impact table fixture can directly clamp this fixing fixture (usually clamping the upper and lower sides of the two server positioning sleeves 1), thereby effectively distributing the force of the impact table fixture and avoiding the problem of additional deformation caused by directly clamping the server 6, ensuring the quality of the shipment. Furthermore, by simultaneously loosening multiple adjusting screws 4 to push and pull the two server positioning sleeves 1 (the adjusting screws 4 slide with the adjusting channel 31), the distance between the two server positioning stops 2 can be flexibly adjusted. This can be flexibly applied to impact testing of servers 6 of different lengths, has good versatility, and allows for the recycling of the fixture, thereby saving development and usage costs. The overall structure is simple, easy to use, and practical.

[0034] Another optional embodiment of the present invention discloses a universal server impact fixing fixture, including two server positioning sleeves 1 that can be fitted onto the front and rear ends of a server 6. Server positioning brackets 2 that can support and limit the front and rear windows of the server 6 are installed on the opposite outer sides of the two server positioning sleeves 1 (i.e., the front side of the front server positioning sleeve 1 and the rear side of the rear server positioning sleeve 1). The universal server impact fixing fixture also includes a plurality of elongated adjustment brackets 3 connected and installed between the two server positioning sleeves 1. The adjustment brackets 3 are arranged in a front-back direction. The adjustment brackets 3 have adjustment channels 31 in the front-back direction along their length direction (front-back direction). Adjustment screws 4 that are screwed and installed into the adjustment channels 31 are respectively screwed onto the two server positioning sleeves 1. The server positioning sleeve 1 has an adjustment frame mounting groove 11 that fits into the adjustment frame 3. The adjustment frame 3 is locked and limited by the adjustment frame mounting groove 11 in the front and rear directions (the upper limit of the adjustment frame 3 in the width direction). After the adjustment screw 4 is loosened, the convenience and stability of the push and pull adjustment of the two server positioning sleeves 1 are ensured, the adjustment frame 3 is prevented from twisting and the two server positioning sleeves 1 are prevented from being misaligned, and the overall force of the server 6 is ensured to be balanced.

[0035] Specifically, two server positioning sleeves 1 are respectively fitted onto the front and rear ends of the server 6 and connected by a long strip-shaped adjustment bracket 3. The front and rear window positions of the server 6 are respectively supported and limited by server positioning baffles 2, forming a closed positioning space for the server 6. During impact testing, the impact table fixture can directly clamp this fixing fixture (usually clamping the upper and lower sides of the two server positioning sleeves 1). Thus, this fixing fixture can effectively distribute the force of the impact table fixture, avoiding the problem of additional deformation caused by directly clamping the server 6, and ensuring the quality of shipment. Furthermore, by loosening the adjusting screw 4, the two server positioning sleeves 1 can be pushed and pulled (the adjusting screw 4 slides with the adjusting hole 31 on the adjustment bracket 3), which can flexibly adjust the distance between the two server positioning baffles 2. The adjustment bracket 3 is locked and limited by the adjustment bracket mounting groove 11, ensuring the convenience and stability of the push and pull adjustment of the two server positioning sleeves 1, avoiding the twisting of the adjustment bracket 3 and the misalignment of the two server positioning sleeves 1, and ensuring the overall force balance of the server 6. This fixture can be flexibly applied to impact testing of servers of different lengths (6), offering good versatility and allowing for fixture recycling, thus saving development and usage costs. The overall structure is simple, easy to use, and highly practical.

The universal server impact fixing fixture also includes a plurality of elongated adjustment brackets 3 connected and installed between the two server positioning sleeves 1. The adjustment brackets 3 are arranged in a front-back direction. The adjustment brackets 3 have adjustment channels 31 in the front-back direction along their length direction (front-back direction). Adjustment screws 4 that are screwed and installed into the adjustment channels 31 are respectively screwed onto the two server positioning sleeves 1. The server positioning sleeve 1 has an adjustment bracket mounting groove 11 that fits into the adjustment bracket 3. The depth of the adjustment bracket mounting groove 11 is greater than the thickness of the adjustment bracket 3. After the adjustment screw 4 is installed, the head of the adjustment screw 4 does not protrude from the surface of the server positioning sleeve 1. This ensures the fit and reliability of the impact table clamp on the upper and lower sides of the server positioning sleeve 1, and avoids the adjustment screw 4 protruding and affecting the clamping of the impact table clamp, thus avoiding unstable clamping and local stress.

[0037] Specifically, two server positioning sleeves 1 are respectively fitted onto the front and rear ends of the server 6 and connected by a long strip-shaped adjustment bracket 3. The front and rear window positions of the server 6 are respectively supported and limited by server positioning baffles 2, forming a closed positioning space for the server 6. During impact testing, the impact table fixture can directly clamp this fixing fixture (clamping the upper and lower sides of the two server positioning sleeves 1), thereby effectively distributing the force of the impact table fixture and avoiding the problem of additional deformation caused by directly clamping the server 6, ensuring the quality of shipment.

Adjustment screws 4 that are screwed and installed into the adjustment channels 31 are respectively screwed onto the two server positioning sleeves 1. The server positioning bracket 2 has a U-shaped plate structure. The server positioning bracket 2 includes an end plate 21 and connecting plates 22 connected to the upper and lower ends of the end plate 21. The connecting plates 22 are fitted and positioned with the upper and lower sides of the server positioning sleeve 1. The two connecting plates 22 are fitted with the upper and lower sides of the server positioning sleeve 1 and are positioned by screwing in the positioning screws. This ensures the stability of the connection between the server positioning bracket 2 and the server positioning sleeve 1 and ensures the reliability of the server positioning bracket 2 in supporting and limiting the front and rear windows of the server 6.

[0039] Specifically, two server positioning sleeves 1 are respectively fitted onto the front and rear ends of the server 6. Two connecting plates 22 are attached to the upper and lower sides of the server positioning sleeves 1, achieving a reliable connection between the server positioning bracket 2 and the server positioning sleeves 1.
