Description

Technical Field

[0001] This utility model relates to the field of titanium welded pipe technology, specifically to a fixture for welding titanium welded pipes that is easy to adjust in orientation. Background Technology

[0002] Titanium welded pipe is a tubular product made of titanium or titanium alloy materials, characterized by its lightweight, high strength, strong corrosion resistance, and good heat resistance. It is made by rolling titanium and titanium alloy coils or wide plates into tubular shapes and then welding them. It is widely used in aerospace, shipbuilding, chemical, and marine engineering fields. During the processing of titanium welded pipe, clamps are required for clamping and welding.

[0003] A search revealed an existing technology, such as CN209986475U, which describes a pipe welding clamp. This clamp includes a base with two symmetrically arranged fixing devices on either side. Each fixing device includes a fixing block fixedly connected to the base, a bracket located above the fixing block and connected to the base, a pressure rod connected to the bracket and movably connected to the bracket, and a pressure block rotatably connected to the bottom end of the pressure rod. The upper surface of the fixing block is a concave arc surface, and the pressure block is correspondingly configured with a concave arc surface. This pipe welding clamp has a simple structure, is easy to carry and disassemble, and is convenient to use.

[0004] In summary, existing pipe welding fixtures have simple structures and are easy to carry and disassemble. However, existing pipe welding fixtures cannot adjust the position of the pipe after clamping. Therefore, a fixture for welding titanium pipes that is easy to adjust in orientation is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixture for welding titanium welded pipes with easily adjustable orientation, comprising a mounting base, a first movable groove on the top of the mounting base, and a lead screw mechanism rotatably disposed inside the first movable groove. One end of the lead screw mechanism is connected to a reduction drive mechanism disposed on the outside of the mounting base. The lead screw mechanism is connected to a first drive block slidably disposed inside the first movable groove, and the first drive block is connected to a positioning platform through a first mounting plate. A second movable groove is provided on the top of the positioning platform, and a second drive block is slidably disposed inside the second movable groove. An electric telescopic rod for driving the second drive block to move is installed inside the second movable groove. The second drive block is connected to the bottom of a fixed plate through a second mounting plate, and two sets of clamping mechanisms for use with titanium welded pipes are installed above the fixed plate.

[0007] Preferably, the reduction drive mechanism includes a first drive motor, which can drive a first gear disposed inside the mounting box to rotate. The first gear meshes with a second gear, and the second gear is mounted on the outside of the lead screw mechanism.

[0008] The above technical solution facilitates the rotation of the lead screw mechanism.

[0009] Preferably, the size of the first gear is smaller than that of the second gear.

[0010] The above technical solution facilitates the deceleration and rotation of the lead screw mechanism.

[0011] Preferably, the clamping mechanism includes a second drive motor, which can drive a bidirectional lead screw mechanism inside the fixed plate to rotate. Two sets of moving blocks are symmetrically arranged on the outside of the bidirectional lead screw mechanism, and the outside of the moving blocks is connected to the moving rod. The top of the moving rod is connected to the push rod arranged on the top of the outside of the fixed plate through a connecting block, and an arc-shaped clamping plate is installed at one end of the push rod.

[0012] The above technical solution facilitates the clamping of the pipe.

[0013] Preferably, the movable rod is slidably connected to the limiting slide rod provided inside the fixed plate.

[0014] The above technical solutions facilitate improved stability during movement.

[0015] Preferably, an anti-slip protective layer is adhered and fixed to the inner side of the arc-shaped clamping plate.

[0016] The above technical solutions improve the anti-slip properties during clamping.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This titanium welded pipe welding clamp, which facilitates position adjustment, solves the problem that existing pipe welding clamps cannot adjust the position of the clamped pipe. It features a first moving groove on the top of the mounting base, with a screw mechanism rotatably mounted inside. One end of the screw mechanism is connected to a reduction drive mechanism on the outside of the mounting base. The screw mechanism is connected to a first driving block slidably mounted inside the first moving groove, and the first driving block is connected to a positioning platform via a first mounting plate. A second moving groove is located on the top of the positioning platform, with a second driving block slidably mounted inside. An electric telescopic rod is installed inside the second moving groove to drive the second driving block. The second driving block is connected to the bottom of a fixed plate via a second mounting plate. Two clamping mechanisms for use with the titanium welded pipe are mounted above the fixed plate. When it is necessary to adjust the position of the clamped pipe, the reduction drive mechanism is activated, causing the pipe to move laterally via the screw mechanism. The electric telescopic rod is then activated, causing the pipe to move longitudinally. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a fixture for welding titanium welded pipes with easily adjustable orientation, based on... Figure 1-3 As shown, the top of the mounting base 1 is provided with a first moving groove 101, and a lead screw mechanism 102 is rotatably arranged inside the first moving groove 101.

[0026] Specifically, one end of the lead screw mechanism 102 is connected to a reduction drive mechanism 2 provided on the outside of the mounting base 1. The reduction drive mechanism 2 facilitates reducing the rotational speed of the lead screw mechanism 102, thereby reducing the pipe's movement speed and facilitating subsequent position adjustment. The reduction drive mechanism 2 includes a first drive motor 201, which drives a first gear 203 located inside the mounting box 202 to rotate. The first gear 203 meshes with a second gear 204, which is mounted on the outside of the lead screw mechanism 102. The size of the first gear 203 is smaller than that of the second gear 204. When the first gear 203 rotates, it can drive the second gear 204 to decelerate and rotate. The lead screw mechanism 102 is connected to the first drive block 3 that is slidably disposed inside the first moving groove 101. The first drive block 3 is connected to the positioning platform 4 through the first mounting plate 301. The top of the positioning platform 4 is provided with a second moving groove 401, and a second drive block 402 is slidably disposed inside the second moving groove 401. An electric telescopic rod 403 that drives the second drive block 402 to move is installed inside the second moving groove 401. The second drive block 402 is connected to the bottom of the fixed plate 5 through the second mounting plate 404.

[0027] When it is necessary to drive the fixed plate 5 to move, the first drive motor 201 is turned on. Under the action of the first drive motor 201, the second gear 204 and the lead screw mechanism 102 are rotated through the first gear 203. Under the action of the lead screw mechanism 102, the first drive block 3 is moved inside the first moving groove 101, thereby driving the fixed plate 5 to move laterally. The electric telescopic rod 403 is turned on. Under the action of the electric telescopic rod 403, the second drive block 402 is moved inside the second moving groove 401, thereby driving the fixed plate 5 to move longitudinally.

[0028] according to Figure 1-2 and Figure 4-5 As shown, two sets of clamping mechanisms 6 are installed above the fixing plate 5 to work with the titanium welded pipe.

[0029] Specifically, the clamping mechanism 6 includes a second drive motor 601, which can drive the bidirectional lead screw mechanism 602 inside the fixed plate 5 to rotate. Two sets of moving blocks 603 are symmetrically arranged on the outer side of the bidirectional lead screw mechanism 602, and the outer side of the moving blocks 603 is connected to the moving rod 604. The top of the moving rod 604 is connected to the push rod 606 on the top of the outer side of the fixed plate 5 through the connecting block 605. An arc-shaped clamping plate 607 is installed at one end of the push rod 606. An anti-slip protective layer 6071 is adhered and fixed on the inner side of the arc-shaped clamping plate 607. The anti-slip protective layer 6071 can be made of rubber material to achieve an anti-slip effect and at the same time prevent the arc-shaped clamping plate 607 from damaging the titanium welded pipe during the clamping process.

[0030] In a further embodiment, the movable rod 604 is slidably connected to the limiting slide rod 608 provided inside the fixed plate 5. By setting the limiting slide rod 608, the moving direction of the movable rod 604 can be limited, thereby improving the stability of the movable rod 604 when it moves.

[0031] When it is necessary to clamp the titanium welded pipe, the titanium welded pipe is lifted to the inside of the two sets of arc-shaped clamping plates 607, and the second drive motor 601 is turned on. Under the action of the second drive motor 601, the bidirectional screw mechanism 602 rotates. The bidirectional screw mechanism 602 drives the two sets of moving blocks 603 to move closer and closer, so that the two sets of moving rods 604 move synchronously. The moving rods 604 drive the push rod 606 and the arc-shaped clamping plates 607 to move through the connecting block 605, so that the titanium welded pipe is clamped by the two sets of arc-shaped clamping plates 607.

[0032] The terms “center,” “longitudinal,” “lateral,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
