Description

Technical Field

[0001] This utility model relates to the field of assembly technology for safety cabinets, and in particular to an assembly fixture suitable for cabinets of various sizes. Background Technology

[0002] Assembly fixtures for biosafety cabinets are auxiliary tools or devices specifically designed for the assembly, commissioning, or maintenance of biosafety cabinets. Their core function is to ensure that each component remains in the correct position and stable state during assembly by precisely positioning, fixing, or supporting the key components of the biosafety cabinet, thus preventing installation deviations from affecting equipment performance.

[0003] However, existing biosafety cabinet assembly processes suffer from numerous problems. Firstly, the lack of precise lateral drive and position adjustment mechanisms makes it difficult to adapt to the assembly position requirements of biosafety cabinets of different sizes, resulting in low assembly efficiency. Secondly, for multi-angle assembly requirements of biosafety cabinets, there is a lack of effective adjustment mechanisms, leading to insufficient assembly flexibility. Furthermore, during clamping, it is impossible to detect lateral shifter misalignment in a timely manner, making it difficult to ensure synchronized and accurate clamping on both sides. This results in poor assembly stability, is prone to significant errors, increases manual adjustment time, and fails to consistently guarantee the assembly quality of the biosafety cabinet.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

It features stable and precise lateral drive, flexible angle adjustment to meet the assembly needs of multiple parts, timely detection of misalignment to ensure clamping synchronization, and improved assembly flexibility, stability, accuracy and efficiency, thus ensuring quality.

[0006] The technical solution adopted by this utility model is as follows: it includes a horizontal mounting plate fixedly connected to the assembly equipment and a limiting guide rail fixed to the top of the horizontal mounting plate. The transverse sliding seat is slidably mounted on the limiting guide rail. The transverse sliding seat is connected to the transverse push drive assembly mounted on the top of the horizontal mounting plate. The mounting base is fixedly mounted on the top of the transverse sliding seat. The rotary adjustment assembly is mounted on the mounting base. The connecting back plate for connecting the clamp is mounted on the rotary adjustment assembly.

[0007] Preferably, in order to enable clamping and assembly from both sides during the assembly of the safety cabinet, the horizontal mounting plate and the connecting back plate are divided into two symmetrical groups on the assembly equipment.

[0008] Preferably, in order to enable the connecting plate to drive the transverse threaded rod to rotate on the first limiting seat by controlling the servo motor to turn on, the transverse push drive assembly includes the servo motor and the first limiting seat fixed at both ends of the top of the horizontal mounting plate. The transverse threaded rod is rotatably inserted into the first limiting seat, and one end of the transverse threaded rod is fixedly connected to the output shaft of the servo motor through the connecting plate.

[0009] Preferably, in order to move the threaded sleeve and the limiting block by controlling the rotation of the transverse screw, thereby driving the transverse sliding seat to move, the threaded sleeve is sleeved on the transverse screw, and the threaded sleeve is fixedly connected to the transverse sliding seat through the limiting block.

[0010] Preferably, in order to limit the threaded sleeve, the limiting block is rotatably connected to the threaded sleeve, and the limiting block is slidably sleeved on the transverse screw.

[0011] Preferably, in order to enable the rotary joint to rotate by controlling the adjustment motor to turn on, the rotary adjustment assembly includes the adjustment motor fixed on the mounting base, the rotary joint being mounted on the mounting base, and the rotary joint being fixedly connected to the output shaft of the adjustment motor via the reducer.

[0012] Preferably, in order to control the rotation of the rotary joint so that the rotary adjusting rod can rotate, and at the same time limit the rotary adjusting rod by the second limiting seat, the rotary adjusting rod is fixedly installed on the rotary joint, one end of the rotary adjusting rod is rotatably inserted into the second limiting seat installed on the top of the transverse seat, and the connecting back plate is fixedly connected to one end of the rotary adjusting rod through the connecting flange.

[0013] Preferably, in order to detect the transverse support by means of the displacement sensor and to detect the deviation of the transverse support in a timely manner, the Z-shaped mounting plate is fixedly installed on the top of the horizontal mounting plate, and the displacement sensor is fixedly installed on the top of the Z-shaped mounting plate, with the displacement sensor corresponding horizontally to the transverse support.

[0014] The beneficial effects of this invention are as follows: the horizontal push drive component enables precise control of the horizontal movement distance and speed of the transverse sliding seat, achieving smooth and accurate lateral drive; the rotary adjustment component allows for flexible adjustment of the connecting backplate angle, meeting the assembly requirements of different parts of multi-size safety cabinets; the symmetrical two sets of structures, combined with displacement sensors, can promptly detect transverse sliding seat misalignment, ensuring synchronized and accurate clamping on both sides.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-4 As shown, this embodiment provides an assembly fixture suitable for multi-size cabinets, including a horizontal mounting plate 1 fixedly connected to assembly equipment and a limiting guide rail 2 fixed to the top of the horizontal mounting plate 1. A transverse sliding seat 3 is slidably mounted on the limiting guide rail 2. The transverse sliding seat 3 is connected to a horizontal push drive assembly 4 mounted on the top of the horizontal mounting plate 1. A mounting base 5 is fixedly mounted on the top of the transverse sliding seat 3. A rotary adjustment assembly 6 is mounted on the mounting base 5. A connecting back plate 7 for connecting the fixture is mounted on the rotary adjustment assembly 6. In use, the horizontal mounting plate 1 is fixed to the assembly equipment. The horizontal push drive assembly 4 drives the transverse sliding seat 3 to slide on the limiting guide rail 2, realizing lateral position adjustment to adapt to the assembly position requirements of safety cabinets of different sizes. The rotary adjustment assembly 6 is mounted on the mounting base 5 on the top of the transverse sliding seat 3 and can drive the connecting back plate 7 to rotate, meeting the multi-angle assembly requirements of the safety cabinet. Through the combination of horizontal push and rotary adjustment, the fixture can be accurately positioned, quickly adapted to multi-size safety cabinets, improve assembly efficiency and accuracy, reduce manual adjustment time and errors, and ensure stable assembly quality.

[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 1As shown, the horizontal mounting plate 1 and the connecting back plate 7 are divided into two symmetrical groups on the assembly equipment. A Z-shaped mounting plate 8 is fixedly installed on the top of the horizontal mounting plate 1, and a displacement sensor 9 is fixedly installed on the top of the Z-shaped mounting plate 8. The displacement sensor 9 is horizontally aligned with the transverse sliding seat 3. When assembling multi-size safety cabinets, the two symmetrical groups of horizontal mounting plates 1 and connecting back plates 7 are clamped and assembled from both sides. The displacement sensor 9 on the Z-shaped mounting plate 8 monitors in real time and is horizontally aligned with the transverse sliding seat 3, accurately capturing its displacement data; it can promptly detect any misalignment of the transverse sliding seat 3, ensuring synchronous and accurate clamping on both sides, improving assembly stability and precision, and ensuring the assembly quality of the safety cabinet.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 4 As shown, the transverse push drive assembly 4 includes a servo motor 401 fixed to both ends of the top of the horizontal mounting plate 1 and a first limiting seat 402. A transverse screw 403 is rotatably inserted into the first limiting seat 402. One end of the transverse screw 403 is fixedly connected to the output shaft of the servo motor 401 via a connecting plate 404. A threaded sleeve 405 is sleeved on the transverse screw 403. The threaded sleeve 405 is fixedly connected to the transverse sliding seat 3 via a limiting block 406. The limiting block 406 is rotatably connected to the threaded sleeve 405 and slidably sleeved on the transverse screw 403. In use, the servo motor 401 at one end of the horizontal mounting plate 1 is started. Its output shaft drives the transverse screw 403 to rotate on the first limiting seat 402 via the connecting plate 404. Because the threaded sleeve 405 is threadedly engaged with the transverse screw 403 and connected to the transverse sliding seat 3 via the limiting block 406, the threaded sleeve 405 will drive the transverse sliding seat 3 to move laterally.

[0024] It can precisely control the movement distance and speed of the transverse sliding seat 3, achieving smooth and accurate lateral drive, and meeting the position adjustment requirements during the assembly of multi-size safety cabinets.

[0025] As a technical optimization solution of this utility model, specifically as follows: Figure 3As shown, the rotary adjustment assembly 6 includes an adjustment motor 601 fixed on the mounting base 5. A rotary joint 602 is mounted on the mounting base 5. The rotary joint 602 is fixedly connected to the output shaft of the adjustment motor 601 via a reducer 603. A rotary adjustment rod 604 is fixedly mounted on the rotary joint 602. One end of the rotary adjustment rod 604 is rotatably inserted into a second limiting seat 605 mounted on the top of the transverse sliding seat 3. The connecting back plate 7 is fixedly connected to one end of the rotary adjustment rod 604 via a connecting flange 606. During assembly, the adjustment motor 601 on the mounting base 5 is started, and its output shaft drives the rotary joint 602 to rotate via the reducer 603, thereby causing the rotary adjustment rod 604 fixed on the rotary joint 602 to rotate. Since one end of the rotary adjustment rod 604 is inserted into the second limiting seat 605, and the other end is fixedly connected to the back plate 7 via the connecting flange 606, the connecting back plate 7 will rotate accordingly. The angle of the connecting back plate 7 can be flexibly adjusted to meet the assembly needs of different parts of multi-size safety cabinets, improving the flexibility and accuracy of assembly.
