Description

Technical Field

[0001] This utility model mainly relates to the field of tee pipe fitting production, specifically to a clamping and fixing device for copper-nickel tee pipe fittings. Background Technology

[0002] In industries such as petrochemicals, shipbuilding, marine engineering, and nuclear power, copper-nickel alloys (such as BFe10-1-1 and BFe30-1-1) are widely used in various pipeline systems due to their excellent resistance to seawater corrosion, resistance to biofouling, good thermal conductivity, and mechanical properties. As a critical connecting component in a pipeline system used for diverting or merging flows, the processing quality of tees (such as welding, cutting, beveling, and inspection) directly affects the safety and reliability of the entire pipeline system.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] Tee fittings have an asymmetrical T-shaped or Y-shaped structure with three mutually perpendicular or angled interfaces (one main pipe inlet, one main pipe outlet, and one branch pipe outlet). Traditional general-purpose clamps (such as vises and three-jaw chucks) are difficult to stably and reliably clamp all three ports at the same time, or can only clamp one or two ports. This causes the fitting to wobble or rotate easily during processing, affecting processing accuracy and safety.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model:

[0007] This utility model provides a clamping and fixing device for copper-nickel tee pipe fittings to solve the technical problems existing in the background art.

[0008] 2. Technical Solution:

[0010] The clamping structure includes a support column, a placement ring at the top of the support column, side plates on both sides of the placement ring, a spring rod inside the side plate, and a fitting ring at one end of the spring rod.

[0011] Furthermore, the angle adjustment structure includes meshing gears, which are rotatably connected to the bottom of the bottom guide structure. The number of meshing gears is set to two, and the two meshing gears mesh with each other. A rotating bar is provided on the outer wall of the meshing gear, and a sliding shaft is provided at one end of the rotating bar. A return spring is provided on one side of the sliding shaft.

[0016] 3. Beneficial effects:

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] This invention features a rotating angle adjustment structure that allows for inward or outward rotation. This structure enables the top clamping structure to rotate inward or outward, aligning it with T-joints at different angles.

[0029] Example

[0030] See attached document Figure 1-4 A copper-nickel tee pipe clamping and fixing device includes a bottom guide structure 1, with angle adjustment structures 3 slidably connected to both sides of one end of the bottom guide structure 1, a clamping structure 2 provided at the neck of the other side of the bottom guide structure 1 and the top of the angle adjustment structure 3, and a side fitting structure 4 rotatably connected to one end of the bottom guide structure 1.

[0031] The clamping structure 2 includes a support column 201, a placement ring 202 at the top of the support column 201, side plates 203 on both sides of the placement ring 202, a spring rod 204 inside the side plate 203, and a fitting ring 205 at one end of the spring rod 204. Copper-nickel tee tubes are then placed onto the tops of the placement rings 202 at different positions. The fitting ring 205 pushes the fitting ring 205 to fit against the outer wall of the copper-nickel tee tube, thereby stably clamping the copper-nickel tee tube and preventing it from shaking during processing.

[0032] Furthermore, the angle adjustment structure 3 includes a meshing gear 301, which is rotatably connected to the bottom of the bottom guide structure 1. Two meshing gears 301 mesh with each other. A rotating bar 302 is provided on the outer wall of each meshing gear 301. A sliding shaft 303 is provided at one end of the rotating bar 302. A return spring 304 is provided on one side of the sliding shaft 303. Manually rotating one meshing gear 301 causes the other meshing gear 301 to rotate, which in turn causes the rotating bar 302 to rotate. The rotating bar 302 then causes the sliding shaft 303 to slide along the inner wall of the guide groove 103. The sliding shaft 303 then compresses or stretches the return spring 304, causing the angle adjustment structure 3 to move the clamping structure 2 to align with the angle of the copper-nickel tee pipe.

[0033] Furthermore, the bottom guide structure 1 includes a base plate 101. Guide grooves 103 are provided on both sides of one end of the base plate 101. An installation strip 104 is provided on the outer wall of the base plate 101. A placement groove 105 is provided inside the installation strip 104. The placement groove 105 is connected to the guide groove 103. An installation groove 102 is provided at the other end of the base plate 101. A return spring 304 is provided inside the placement groove 105. The guide groove 103 is slidably connected to the sliding shaft 303. When it is necessary to clamp and fix the copper-nickel tee pipe for subsequent processing, the base plate 101 is placed on the plane, and then the clamping structure 2 is moved to different positions by adjusting the angle adjustment structure 3 to clamp the copper-nickel tee pipe at different angles.

[0034] Furthermore, the side-fitting structure 4 includes a rotating shaft 401, which is rotatably connected to the interior of the mounting groove 102. A support rod 402 is provided on the outer wall of the rotating shaft 401. A mounting plate 403 is provided at one end of the support rod 402. A slot 404 is opened on the outer wall of the mounting plate 403. A push spring 405 is provided inside the slot 404. A fitting strip 406 is provided at one end of the push spring 405. The cross-section of the fitting strip 406 is set as a right-angled triangle. After the copper-nickel tee pipe is fixed, the support rod 402 is manually rotated, which drives the rotating shaft 401 to rotate. Then, one end of the support rod 402 is aligned with one end of the copper-nickel tee pipe. A spring is provided at the connection position between the support rod 402 and the mounting plate 403. The spring pushes the mounting plate 403 to one side, so that the fitting strip 406 on the outer wall of the mounting plate 403 fits against the inner wall of the tee pipe, thus fixing the position of the tee pipe a second time.

[0035] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
