Description

Technical Field

[0001] This utility model relates to the technical field of pipe fitting processing equipment, specifically a precision welding device for high-pressure pipe fittings. Background Technology

[0002] High-pressure pipe fittings require welding during manufacturing. Welding firmly connects two sections of the fitting together, forming a unified structure. This enhances the fitting's mechanical strength and durability, enabling it to withstand higher pressures and more complex operating conditions, such as those described in patent number [not specified].

[0003] CN202323627636.2 discloses a precision welding device for pipe fittings. This solution uses two fixed rings with abutment members (threaded columns) on them. The threaded columns can extend and retract when rotated, thereby driving the abutment wheels to move. The high-pressure pipe fittings are fixed through the cooperation of the abutment wheels, which facilitates the welding operation and ensures welding accuracy. However, this method has the following defects and shortcomings. First, the extension and retraction of the abutment wheels by the rotation of the threaded columns is not convenient to operate. It is not possible to realize the expansion and retraction of the abutment wheels simultaneously, making operation inconvenient and difficult to control the extension and retraction distance of the abutment wheels. Consequently, it is difficult to ensure the precision of pipe fitting fixation, and it is easy to deviate, making it difficult to control the welding precision of the pipe fittings. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a precision welding device for high-pressure pipe fittings. By incorporating a clamping mechanism consisting of a ring body, a track plate, clamping components, a gear ring, a rotating ring, and a ring plate, the pipe fitting to be welded is extended into the ring body and ring plate. A self-locking motor is then driven to rotate the gears. The engagement between the gears and the gear ring causes the ring plate to rotate, changing the angle of the arc-shaped groove on the ring plate. This causes the limiting rod to move, resulting in the simultaneous expansion and contraction of multiple clamping components, effectively clamping the pipe fitting and ensuring the welding effect of the high-pressure pipe fitting. This solves the problems of poor operation convenience and low welding accuracy in current devices.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A precision welding device for high-pressure pipe fittings includes a worktable. Two symmetrically distributed clamping modules are arranged on the upper surface of the worktable. Each clamping module includes two clamping mechanisms. A first support is fixedly connected to the bottom of one clamping mechanism. The first support is fixed to the worktable, and a telescopic mechanism is installed on one side of the worktable near the first support. A second support is mounted on the telescopic mechanism. The other clamping mechanism is fixed to the second support. Each clamping mechanism includes: a ring-shaped body; an array of track plates fixed to one side of the ring-shaped body; and clamping components slidably connected to the corresponding track plates.

[0009] Furthermore, the clamping component includes a sliding block slidably connected to the track plate, and a support fixedly connected to one side of the sliding block. A round rod is fixedly connected to the support, and a roller is installed at the end of the round rod.

[0010] Furthermore, a limiting rod is fixedly connected to one side of the sliding block. The limiting rod extends to the outside of the annular body through the clearance cavity groove opened on the track plate. A rotating ring is rotatably connected to one side of the annular body, and an annular plate is fixedly connected to the rotating ring. The annular plate is provided with an array of arc-shaped grooves, and the limiting rod extends to the corresponding arc-shaped groove.

[0011] Furthermore, a gear ring is fixedly connected to the annular plate, and a self-locking motor is installed on one side of the annular body. A gear is fixedly connected to the output shaft of the self-locking motor, and the gear meshes with the gear ring.

[0012] Furthermore, the telescopic mechanism includes a limiting frame fixedly connected to the worktable, and a slider slidably connected to the limiting frame. The slider is fixedly connected to the second bracket, and a lead screw is rotatably connected to the limiting frame. The slider has a screw hole adapted to the lead screw at the corresponding position, and a servo motor for driving the lead screw to rotate is installed on one side of the limiting frame.

[0013] Furthermore, a mounting bracket is fixedly connected to one side of the workbench, and a cylinder is mounted on the upper part of the mounting bracket, with a welding torch installed at the bottom of the cylinder.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a precision welding device for high-pressure pipe fittings, which has the following beneficial effects:

[0016] This utility model incorporates two clamping mechanisms within a clamping module. One of these mechanisms is telescopic, allowing for adjustment of the clamping position of the pipe fitting. This facilitates the use of pipe fittings of varying lengths. The clamping mechanism effectively clamps the pipe fitting and is easy to operate, enabling quick and easy fixing of the pipe fitting and facilitating high-precision welding. The clamping mechanism comprises a ring body, a track plate, clamping components, a gear ring, a ring plate gear, and a self-locking motor. In use, the pipe fitting to be processed is placed inside the ring body and ring plate. The self-locking motor is then activated, causing the gear to rotate. The meshing relationship between the wheel and the toothed ring causes the annular plate to rotate. When the annular plate rotates, the angle of the arc groove on the annular plate changes. The limiting rod is located in the arc groove, which in turn drives the limiting rod to move, causing the sliding block to move on the corresponding track plate. This drives the round rod and roller to move, so that the roller contacts the outer wall of the pipe fitting, forming a clamping of the pipe fitting. After clamping, the pipe fitting can rotate, which facilitates welding at various positions of its connection. This method can quickly clamp the pipe fitting, is very convenient to use, and the roller can extend and retract synchronously, which can ensure the clamping effect of the pipe fitting and prevent skewing.

[0024] Example

[0025] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of the present invention provides a precision welding device for high-pressure pipe fittings, including a workbench 1. Two symmetrically distributed clamping modules are arranged on the upper surface of the workbench 1. These clamping modules clamp two pipe fittings, facilitating welding between them. Each clamping module includes two clamping mechanisms 5. A first support 2 is fixedly connected to the bottom of one clamping mechanism 5, and the first support 2 is fixed to the workbench 1. This clamping mechanism 5 cannot move, thus clamping the pipe fitting on one side. A telescopic mechanism 3 is installed on one side of the workbench 1, located next to the first support 2. A second support is mounted on the telescopic mechanism 3. 4. Another clamping mechanism 5 is fixed on the second bracket 4, so that the clamping mechanism 5 can move under the action of the telescopic mechanism 3, and adjust the distance between the two clamping mechanisms 5, thereby facilitating the welding of different pipe fittings and making it more versatile; the clamping mechanism 5 includes: an annular body 501, which is the main body of the clamping mechanism 5; a track plate 502, which is fixed in an array on one side of the annular body 501; and a clamping component 503, which is slidably connected to the corresponding track plate 502. The clamping component 503 can slide on the corresponding track plate 502, and the clamping function of the pipe fitting is realized through the mutual cooperation of the clamping components 503.

[0026] like Figure 3 and Figure 4 As shown, in some embodiments, the clamping component 503 includes a sliding block 5031 slidably connected to the track plate 502, and a support 5032 fixedly connected to one side of the sliding block 5031.

Furthermore, a rotating ring 506 is rotatably connected to one side of the annular body 501. A ring plate 507 is fixedly connected to the rotating ring 506. The rotating ring 506 enables the ring plate 507 to rotate. The ring plate 507 has an array of arc-shaped grooves 508. The limiting rod 5035 extends to the corresponding arc-shaped groove 508. When the ring plate 507 rotates, the limiting rod 5035 can be extended or retracted through the limiting relationship of the arc-shaped grooves 508, thereby causing the sliding block 5031 to move and realizing the driving effect of the movement of the sliding block 5031.

It should be noted that the self-locking motor 5010 can drive the gear 509 to rotate, and the gear 509 meshes with the toothed ring 504, thereby realizing the rotation drive of the annular plate 507. The self-locking motor 5010 has a certain self-locking effect, realizing the effective clamping of the pipe fitting.

[0029] like Figure 1 and Figure 5 As shown, in some embodiments, the telescopic mechanism 3 includes a limiting frame 301 fixedly connected to the workbench 1, and a slider 303 slidably connected to the limiting frame 301.

A servo motor 304 for driving the lead screw 302 to rotate is installed on one side of the limiting frame 301. The servo motor 304 can drive the lead screw 302 to rotate, so that the slider 303 slides on the limiting frame 301. The slider 303 is fixedly connected to the second bracket 4, thereby driving the second bracket 4 and the clamping mechanism 5 to move.

[0030] like Figure 1 As shown, in some embodiments, a mounting frame 6 is fixedly connected to one side of the workbench 1, and a cylinder 8 is mounted on the upper part of the mounting frame 6, and a welding torch 7 is provided at the bottom of the cylinder 8; the mounting frame 6 realizes the installation of the cylinder 8, and the cylinder 8 can drive the welding torch 7 to extend and retract, so as to realize the welding function of the outer seam of the pipe fitting.
