Description

Technical Field

[0001] This utility model belongs to the field of pipe welding technology, and more specifically, it relates to a positioning structure for pipe welding. Background Technology

[0002] Pipeline internal wall cladding equipment is a specialized automated welding device used to clad the inner walls of pipelines with corrosion-resistant and wear-resistant alloy materials, thereby extending the service life of the pipelines. The equipment typically consists of a wire feeding system, welding power source, control system, and traveling mechanism, and is suitable for pipeline repair and manufacturing in industries such as petroleum, chemical, and power.

[0003] Currently, some pipe fitting internal wall surfacing equipment is only suitable for positioning and fixing straight pipes. However, when faced with multi-angle bends, these devices cannot achieve effective positioning and fixing, which in turn affects the surfacing effect of the pipe fitting internal wall surfacing equipment on the inner wall of the pipe.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a positioning structure for weld overlay pipe fittings in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a positioning structure for weld overlay pipe fittings, which is achieved by the following specific technical means: A positioning structure for weld overlay pipe fittings includes a base, a telescopic mechanism, and a pair of fixing mechanisms. A mounting seat 1 is bolted to the middle of the upper surface of the base. A support block 1 is mounted on the upper surface of the mounting seat 1, and a connector 1 is mounted on the upper surface of the support block 1. A mounting seat 2 is bolted to the edge of the upper surface of the base. A support block 2 is mounted on the upper surface of the mounting seat 2, and a connector 2 is mounted on the upper surface of the support block 2. A support seat is rotatably connected to the bottom surface of the telescopic mechanism. A mounting block 1 is mounted on the bottom surface of the support seat. The mounting block 1 is rotatably connected to the connector 2. A connector 3 is mounted on the top of the telescopic mechanism. A mounting block 2 is mounted on one side of each fixing mechanism. The pair of fixing mechanisms are rotatably connected to the connector 1 and connector 3 respectively via the mounting block 2.

[0006] Furthermore, the telescopic mechanism includes a sleeve rod and a lead screw. The upper end face of the sleeve rod is provided with a threaded groove, the lead screw is threadedly connected to the threaded groove, the bottom end of the sleeve rod is rotatably connected to the support base, and the top end of the lead screw is fixedly connected to the bottom end face of the connecting head three.

[0007] Furthermore, a rotating block is installed on the outer periphery of the top end of the sleeve rod, and the surface of the rotating block is provided with anti-slip texture.

[0008] Furthermore, the fixing mechanism includes a C-shaped frame, threaded rods, and clamping blocks. The mounting block is fixedly connected to one side of the C-shaped frame, and a pair of threaded rods are threadedly connected to both sides of the C-shaped frame. A clamping block is installed at the opposite end of each pair of threaded rods.

[0009] Furthermore, a rotating block 2 is installed at one end of the threaded rod, which passes through one side of the C-shaped frame.

[0010] Furthermore, a limiting rod is installed on one side of the clamping block, and one end of the limiting rod passes through one side of the C-shaped frame and is movably connected to the C-shaped frame.

[0011] Furthermore, a level is installed on the upper surface of the C-shaped frame connected to the telescopic mechanism. Compared with the prior art, the present invention has the following beneficial effects: In this utility model, the operator first uses the fixing mechanism above the mounting base to securely fix the lower end of the bend, and then uses the fixing mechanism above the telescopic mechanism to fix the upper end of the bend. Next, the operator operates the rotating block to drive the sleeve rod to rotate, causing the lead screw to move outward and disengage from the thread groove. The lead screw, through the cooperation of the connecting head three and the mounting block two, drives the fixing mechanism to precisely adjust the angle. With the help of a level, the fixing mechanism is adjusted to be horizontal, ensuring that the upper end of the bend is horizontally aligned. This not only provides convenience for the surfacing operation of the pipe fitting inner wall surfacing equipment, but also fixes multi-angle bends and improves the versatility of the device.

[0020] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a positioning structure for weld overlay pipe fittings, including a base 1, a telescopic mechanism 2, and a pair of fixing mechanisms 3. A mounting seat 4 is bolted to the middle of the upper surface of the base 1. A support block 401 is mounted on the upper surface of the mounting seat 4, and a connector 402 is mounted on the upper surface of the support block 401. A mounting seat 5 is bolted to the edge of the upper surface of the base 1. A support block 501 is mounted on the upper surface of the mounting seat 5, and a connector 502 is mounted on the upper surface of the support block 501. A support seat 202 is rotatably connected to the bottom surface of the telescopic mechanism 2. A mounting block 201 is mounted on the bottom surface of the support seat 202 and rotatably connected to the connector 502. A connector 203 is mounted on the top of the telescopic mechanism 2. A mounting block 301 is mounted on one side of the fixing mechanism 3. The pair of fixing mechanisms 3 are rotatably connected to the connector 402 and connector 203 respectively via the mounting block 301.

[0021] The telescopic mechanism 2 includes a sleeve rod 204 and a lead screw 205. The upper end face of the sleeve rod 204 is provided with a threaded groove 206. The lead screw 205 is threadedly connected to the threaded groove 206. The bottom end of the sleeve rod 204 is rotatably connected to the support base 202. The top end of the lead screw 205 is fixedly connected to the bottom end face of the connecting head 3 203. When the operator operates the rotating block, the sleeve rod 204 is rotated. The rotation of the sleeve rod 204 causes the lead screw 205 to move outward and disengage from the threaded groove 206. Through the coordinated action of the connecting head 3 203 and the mounting block 2 301, the lead screw 205 drives the angle of the fixing mechanism 3 to be precisely adjusted.

[0022] Among them, a rotating block 207 is installed on the outer periphery of the top end of the sleeve rod 204. The surface of the rotating block 207 is provided with anti-slip texture, which can increase the friction of the rotating block 207 surface.

[0023] The fixing mechanism 3 includes a U-shaped frame 302, a threaded rod 303 and a clamping block 304. The mounting block 301 is fixedly connected to one side of the U-shaped frame 302. A pair of threaded rods 303 are threadedly connected to both sides of the U-shaped frame 302. A clamping block 304 is installed at the opposite end of each pair of threaded rods 303.

[0024] One end of the threaded rod 303 passes through one side of the bracket 302 and is equipped with a rotating block 305. The rotating block 305 drives the threaded rod 303 to rotate, and the rotating rod 303 drives the clamping block 304 to move towards the middle and clamp the pipe fitting.

[0025] Among them, a limiting rod 306 is installed on one side of the clamping block 304. One end of the limiting rod 306 passes through one side of the C-shaped frame 302 and is movably connected to the C-shaped frame 302. The limiting rod 306 can limit the movement of the clamping block 304.

[0026] Among them, a level 6 is installed on the upper end of the C-shaped frame 302 connected to the telescopic mechanism 2. With the help of the level 6, the fixing mechanism 3 is adjusted to a horizontal state to ensure that the upper end of the bend is horizontally aligned.

[0027] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the structure and principle of the components known to those skilled in the art can be known by those skilled in the art through technical manuals or conventional experimental methods.

[0028] The working principle of this embodiment: First, the worker uses the fixing mechanism 3 above the mounting base to securely fix the lower end of the bend. Then, the worker uses the fixing mechanism 3 above the telescopic mechanism 2 to fix the upper end of the bend. Next, the worker operates the rotating block to rotate the sleeve rod 204. The rotation of the sleeve rod 204 causes the lead screw 205 to move outward and disengage from the thread groove 206. Through the coordinated action of the connecting head 3 203 and the mounting block 2 301, the lead screw 205 drives the fixing mechanism 3 to make precise adjustments to its angle. With the assistance of the level 6, the fixing mechanism 3 is adjusted to a horizontal state to ensure that the upper end of the bend is horizontally aligned, thus facilitating the welding operation of the pipe fitting inner wall welding equipment.
