Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing technology, specifically a pipe fitting limiting structure for a pipe fitting welding platform. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding uses a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. In addition to its use in factories, welding can also be performed in various environments, such as outdoors, underwater, and in space.

[0003] According to a pipe fitting limiting structure for a pipe welding platform (Announcement No.: CN218169289U), the aforementioned application utilizes a drive motor, a bidirectional threaded rod, a moving plate, an arc-shaped clamping plate, a drive gear, a driven gear, a rotating rod, a rotating shaft, and a sliding groove. This allows for the horizontal movement of the arc-shaped clamping plate before welding, thereby clamping and limiting the pipe fitting. This addresses the inconvenience of existing welding devices, which often place pipe fittings directly on the welding platform for welding, making it difficult to fix and limit the pipe fittings. This can lead to the pipe fittings sliding and rolling during welding, affecting the welding effect. The fixed frame, sliding column, return spring, and pressure plate facilitate clamping and limiting the pipe fittings during clamping.

[0004] However, in the aforementioned application, the pipe fitting limiting structure relies on the continuous rotation of a drive motor to push a bidirectional threaded rod when clamping the pipe fitting, thereby clamping the pipe fitting through a moving plate and an arc-shaped clamping plate. However, during this process, if the operator fails to stop the clamping device in time, or if the control system malfunctions, excessive clamping force may occur. In extreme cases, this excessive clamping force can cause deformation of the pipe fitting, affecting not only its appearance and quality but also potentially its subsequent performance. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe fitting limiting structure for a pipe welding platform to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe fitting limiting structure for a pipe welding platform, comprising a base, a groove on the top of the base, a screw rod rotatably connected to the inner wall of the groove, a movable column passing through the screw rod, the movable column being threadedly connected to the screw rod, the movable column being slidably connected to the inner wall of the groove, a clamping plate fixed to the top of the movable column, and a fixing component and a protective component provided inside and on the surface of the clamping plate, the fixing component comprising: a cavity, a stabilizing plate, a movable plate, and a screw rod.

[0007] The protective components include:

[0008] The round block is used to limit the movement of the screw.

[0009] The abutment rod is used to move the moving block.

[0010] The moving block is used to synchronously drive the movement of the lever.

[0011] Preferably, the circular block is penetrated by the second screw and fixedly connected to the second screw. A limiting groove is formed on the surface of the circular block. Two sets of movable plates and two sets of stabilizing plates are provided. A contact rod is slidably connected to the surface of one set of movable plates. A movable rod is hinged to the side of the contact rod away from the movable plate. The end of the movable rod away from the contact rod is hinged to the surface of one set of stabilizing plates. A through hole is formed on the surface of the clamping plate. The end of the contact rod away from the movable rod passes through the through hole. A fixing plate is fixed to the inner wall of the cavity. A second spring is fixed to the surface of the fixing plate. The second spring is located away from the fixing plate. One end of the device is fixed with a movable block, which is slidably connected to the inner wall of the cavity. The surface of the movable block has an abutment groove and a sliding groove. The inner wall of the sliding groove is slidably connected with a locking rod. The surface of the locking rod is fixed with a spring three. The end of the spring three away from the locking rod is fixed to the inner wall of the sliding groove. The stabilizing plate and the movable plate move closer to each other, the movable rod flips, the abutment rod moves closer to the movable block, the abutment rod abuts against the inclined surface of the abutment groove, the movable block and the locking rod move closer to the round block, the locking rod enters the limiting groove, and the side of the locking rod away from the inclined surface abuts against the inner wall of the limiting groove, thus limiting the round block and the screw two.

[0012] Preferably, the cavity is formed inside the clamping plate. A circular plate is rotatably connected to the inner wall of the cavity. An arc-shaped hole is formed on the surface of the circular plate. A short rod abuts against the inner wall of the arc-shaped hole. The end of the short rod away from the arc-shaped hole passes through the clamping plate and a fixing block passes through it. The fixing block is fixedly connected to the short rod and slidably connected to the inner wall of the cavity. A movable plate is fixed to the end of the short rod away from the arc-shaped hole. The movable plate is slidably connected to the surface of the clamping plate. A spring is fixed to the surface of the movable plate. A stabilizing plate is fixed to the end of the spring away from the movable plate. The stabilizing plate slides... The clamping plate is connected to the surface of the clamping plate. Two sets of fixing blocks are provided. A knob is rotatably connected to the surface of the clamping plate. The output shaft of the knob passes through the clamping plate. A second screw is fixed to the surface of the output shaft of the knob. The second screw passes through one of the two sets of fixing blocks and is threadedly connected to the fixing block. When the knob is turned clockwise, the second screw rotates, and the fixing block moves closer to the center of the circular plate. The short rod moves and its surface abuts against the inner wall of the arc-shaped hole, which makes the circular plate rotate clockwise. This makes the short rod, fixing block, and moving plate move synchronously. At this time, the stabilizing plate moves synchronously through the first spring, and the stabilizing plate clamps the pipe.

[0013] Preferably, the end of the lever away from the spring is set as an inclined surface, and the cross-section of the abutment groove is triangular. When the inclined surface of the lever is abutted, the lever can move into the sliding groove, and when the abutment groove is abutted, the moving block can move.

[0014] Preferably, a rocker arm is rotatably connected to the surface of the base, the output shaft of the rocker arm passes through the base, and the output shaft of the rocker arm is fixed to the surface of the screw, so as to facilitate the synchronous rotation of the screw.

[0015] Preferably, the screw has two opposite threads, so that when the screw rotates, the moving columns move closer or further apart synchronously.

[0016] Compared with the prior art, this utility model provides a pipe fitting limiting structure for a pipe welding platform, which has the following beneficial effects:

[0017] 1. This pipe welding platform uses a pipe fitting limiting structure. Through the set protective components, when the stabilizing plate and the moving plate approach each other, the movable rod can be flipped, and the abutting rod moves closer to the moving block. The abutting rod abuts against the inclined surface of the abutting groove, which can drive the moving block and the clamping rod to move closer to the round block. When the clamping rod enters the limiting groove, the side of the clamping rod away from the inclined surface abuts against the inner wall of the limiting groove, which can limit the round block and the screw, so that the knob can not continue to rotate, avoiding excessive clamping force and causing pipe deformation. Reversing the knob, the inner wall of the limiting groove abuts against the inclined surface of the clamping rod, so that the clamping rod moves into the sliding groove without affecting the reverse rotation of the round block and the screw, thus allowing the stabilizing plate and the moving plate to return to normal, and the pipe fitting can be released.

[0018] 2. The pipe welding platform uses a pipe limiting structure. By setting a fixing component, rotating the knob forward will rotate the screw two, causing the fixing block to move closer to the center of the circular plate. The short rod moves and its surface abuts against the inner wall of the arc-shaped hole, which will cause the circular plate to rotate forward. This will cause the short rod, fixing block, and moving plate to move synchronously. At this time, the spring one will drive the stabilizing plate to move synchronously. The stabilizing plate will then clamp the pipe, facilitating welding. Attached Figure Description

[0026] like Figures 1-6As shown, this utility model provides a technical solution: a pipe fitting limiting structure for a pipe welding platform, including a base 1, a groove 2 on the top of the base 1, a screw 3 rotatably connected to the inner wall of the groove 2, a movable column 5 passing through the screw 3, the movable column 5 being threadedly connected to the screw 3, the movable column 5 being slidably connected to the inner wall of the groove 2, a clamping plate 6 fixed to the top of the movable column 5, and a fixing component 7 and a protective component 8 provided inside and on the surface of the clamping plate 6.

A through hole is formed on the surface of the clamping plate 6. The end of the abutment rod 82 away from the movable rod 83 passes through the through hole. A fixing plate 84 is fixed to the inner wall of the cavity 70. A second spring 85 is fixed to the surface of the fixing plate 84. A moving block 86 is fixed to the end of the second spring 85 away from the fixing plate 84. The moving block 86 is slidably connected to the inner wall of the cavity 70. An abutment groove 87 and a sliding groove 88 are formed on the surface of the moving block 86. A locking rod 800 is slidably connected to the inner wall of the sliding groove 88. A third spring 89 is fixed to the surface of the locking rod 800. The end of the third spring 89 away from the locking rod 800... Fixed to the inner wall of the slide groove 88, the end of the clamping rod 800 away from the spring 89 is set as an inclined surface, the cross-section of the contact groove 87 is triangular, the stabilizing plate 77 and the moving plate 75 approach each other, the movable rod 83 flips, the contact rod 82 moves close to the moving block 86, the contact rod 82 abuts against the inclined surface of the contact groove 87, the moving block 86 and the clamping rod 800 move close to the round block 80, the clamping rod 800 enters the limiting groove 81, the side of the clamping rod 80 away from the inclined surface abuts against the inner wall of the limiting groove 81, which can limit the round block 80. At this time, the screw 79 can no longer rotate, which can prevent the knob 78 from continuing to rotate, avoiding excessive clamping force and causing deformation of the pipe fitting.

[0027] A cavity 70 is formed inside the clamping plate 6. A circular plate 71 is rotatably connected to the inner wall of the cavity 70. An arc-shaped hole 72 is formed on the surface of the circular plate 71. A short rod 73 abuts against the inner wall of the arc-shaped hole 72. The end of the short rod 73 away from the arc-shaped hole 72 passes through the clamping plate 6 and a fixing block 74 passes through it. The fixing block 74 is fixedly connected to the short rod 73 and slidably connected to the inner wall of the cavity 70. A movable plate 75 is fixed to the end of the short rod 73 away from the arc-shaped hole 72. The movable plate 75 is slidably connected to the surface of the clamping plate 6. A spring 76 is fixed to the surface of the movable plate 75. A stabilizing plate 77 is fixed to the end of the spring 76 away from the movable plate 75 and slidably connected to the surface of the clamping plate 6. Two sets of fixtures are provided. A knob 78 is rotatably connected to the surface of the clamping plate 6. The output shaft of the knob 78 passes through the clamping plate 6. A screw 79 is fixed to the surface of the output shaft of the knob 78. The screw 79 passes through one of the two sets of fixing blocks 74 and is threadedly connected to the fixing block 74. When the knob 78 is turned clockwise, the screw 79 rotates, the fixing block 74 moves closer to the center of the circular plate 71, and the short rod 73 moves. The surface of the short rod 73 abuts against the inner wall of the arc-shaped hole 72, which makes the circular plate 71 rotate clockwise. This makes the short rods 73, the fixing blocks 74, and the moving plate 75 move synchronously. At this time, the stabilizing plate 77 moves synchronously through the spring 76. The stabilizing plate 77 clamps the pipe. The knob 78 is turned counterclockwise to release the clamps.

[0028] A rocker arm 4 is rotatably connected to the surface of the base 1. The output shaft of the rocker arm 4 passes through the base 1 and is fixed to the surface of the screw 3, facilitating the rotation of the screw 3. The screw 3 has two opposite threads, which, when rotated, allow the moving columns 5 to move closer or further apart synchronously.

[0029] When processing the pipe fitting is required, the fitting is placed between the clamping plates 6. Rotating the rocker arm 4 rotates the screw 3, causing the moving column 5 to move the clamping plates 6 closer together, initially clamping the fitting. Rotating the knob 78 rotates the screw 79, causing the fixed block 74 to move closer to the center of the circular plate 71, simultaneously moving the short rod 73. The surface of the short rod 73 then contacts the inner wall of the arc-shaped hole 72, causing the circular plate 71 to rotate clockwise. This allows the short rods 73, fixed block 74, and moving plate 75 to move synchronously. Spring 76 then moves the stabilizing plate 77 synchronously, clamping the fitting. Continuing to rotate the knob 78 causes the stabilizing plate 77 and moving plate 75 to move closer together, causing the movable rod 83 to flip, moving the contact rod 82 closer to the moving block 86. The contact rod 82 then contacts the inclined surface of the contact groove 87, moving the moving block 86 and the clamping rod 800 closer to the circular block 86. 0. When the surface of the locking rod 800 contacts the surface of the round block 80, the locking rod 800 moves into the slide groove 88, and the spring 89 is compressed. When the position of the locking rod 800 is parallel to the limiting groove 81, the spring 89 is released, and the locking rod 800 enters the limiting groove 81. At this time, the side of the locking rod 800 away from the inclined plane contacts the inner wall of the limiting groove 81, which can limit the round block 80. At this time, the screw 79 can no longer rotate, which can prevent the knob 78 from rotating further, thus avoiding... To prevent excessive clamping force from causing deformation of the pipe fitting, welding can proceed normally. When it is necessary to remove the pipe fitting, reverse knob 78. The inner wall of the limit groove 81 abuts against the inclined surface of the clamping rod 800, causing the clamping rod 800 to move into the sliding groove 88. This will not affect the reversal of the round block 80 and the screw rod 79, thus allowing the stabilizing plate 77 and the moving plate 75 to reset normally, and the pipe fitting can be released. At the same time, reverse rocker arm 4, causing the moving column 5 to move the clamping plate 6 away from each other, making it convenient for personnel to remove the pipe fitting.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
