Description

Technical Field

[0001] This utility model relates to the field of nitrogen spring production technology, specifically a fixture for producing nitrogen springs with multi-angle adjustable properties. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN222243614U, which discloses a positioning fixture for processing nitrogen springs, including a housing. In this invention, a knob is used to compress the helical spring through a first fixed shaft, allowing it to slide on the inner wall of the placement shaft and the outer wall of the second fixed shaft. Then, the knob is used again to rotate the second fixed shaft through the first fixed shaft, thereby rotating the locking pin and causing it to slide out of the inner wall of the locking groove, thus achieving the effect of disassembling the housing and quickly installing it. The existing technical solution described above has the following drawbacks: it adopts a fixed structure, which can only achieve simple positioning in the vertical direction. If holes of different angles need to be processed, the workpiece needs to be repeatedly disassembled and the fixture direction adjusted.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides a multi-angle adjustable fixture for the production of nitrogen springs, which has the following advantages: This multi-angle adjustable nitrogen spring production fixture features a support mechanism, a fixing mechanism, and a rotating mechanism. An arc-shaped hole is formed on the inner side of the rotating block, through which a support rod passes, forming a limiting track to restrict the tilt angle range of the operating table. Multiple circular holes are formed on the arc-shaped block at the front bottom of the operating table for inserting the locking rod of the fixing mechanism to lock the angle. The cooperation between the arc-shaped hole and the support rod ensures structural stability during tilt adjustment, preventing swaying caused by single-point support. Pressing down on the horizontal plate drives the vertical plate downwards, and the pressure plate squeezes the wedge block, causing the two moving plates to slide back-to-back. The locking rod exits the circular hole. The operating table is manually tilted to the target angle using the handle, aligning the corresponding circular hole with the locking rod. Releasing the horizontal plate causes the telescopic spring to push the moving plate back to its original position, and the locking rod re-inserts into the circular hole, completing the fixation. Furthermore, a rotary motor drives a ring gear via a drive gear, causing the turntable and outer casing assembly to rotate horizontally. The motor frame is fixed to the left side of the operating table to ensure transmission stability, enabling stepless rotation of the workpiece on the horizontal plane. Combined with tilt adjustment, it can cover any spatial angle required for processing, achieving the purpose of multi-angle adjustment. Attached Figure Description

When rotating horizontally, start the rotary motor 55 through the control panel to drive the turntable 52 to rotate to the specified position. Place the nitrogen spring cylinder outside the outer box 61, start the servo motor 77, and the clamping plate 76 will automatically clamp the workpiece. According to the process requirements, perform drilling and grinding operations on the tilted or rotated workpiece. During the processing, the workpiece position can be finely adjusted through the rotating mechanism 5 without re-clamping. When finished and disassembling, stop the servo motor 77, the clamping plate 76 will automatically release, remove the workpiece, clean the chips on the fixture surface, and apply anti-rust oil.

[0022] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0023] In summary, this multi-angle adjustable nitrogen spring production fixture, through the setting of a support mechanism 3, a fixing mechanism 4, and a rotating mechanism 5, has an arc-shaped hole 33 on the inner side of the rotating block 32. The support rod 34 passes through the arc-shaped hole 33 to form a limiting track, limiting the tilt angle range of the operating table 2. The arc-shaped block 35 on the front side of the bottom of the operating table 2 has multiple round holes 36 for the insertion of the locking rod 404 of the fixing mechanism 4 to achieve angle locking. The cooperation between the arc-shaped hole 33 and the support rod 34 ensures the structural stability during tilt adjustment and avoids swaying caused by single-point support. Pressing down on the horizontal plate 410 drives the vertical plate 408 to move down, the pressure plate 409 squeezes the wedge block 406, causing the two moving plates 403 to slide back to back, and the locking rod 404 exits the round hole 36, allowing the tilt angle to be locked. Manually tilt the operating table 2 to the target angle using handle 9, aligning the corresponding circular hole 36 with the clamping rod 404. Release the horizontal plate 410, and the telescopic spring 405 pushes the moving plate 403 to reset. The clamping rod 404 is then inserted into the circular hole 36, completing the fixation. Next, the rotary motor 55 drives the ring gear 53 through the drive gear 56, causing the turntable 52 and the outer box assembly 6 to rotate horizontally. The motor frame 54 is fixed to the left side of the operating table 2 to ensure transmission stability, achieving stepless rotation of the workpiece on the horizontal plane. Combined with tilt adjustment, it can cover any spatial angle required for processing, achieving the purpose of multi-angle adjustment. This solves the problem that with a fixed structure, only simple vertical positioning can be achieved, and if different angle holes need to be processed, the workpiece needs to be repeatedly disassembled and the fixture direction adjusted.
