Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a ceramic gasket tightening device for welding. Background Technology

[0002] Ceramic gaskets are gasket products made of ceramic materials, typically possessing excellent wear resistance, corrosion resistance, high-temperature resistance, and insulation properties. Ceramic gaskets have high hardness and a low coefficient of friction, making them widely used in many applications requiring wear resistance and friction reduction, such as sliding parts in mechanical equipment, elbows and pump bodies in chemical pipelines, and insulating components in electronic equipment. Ceramic gaskets can effectively extend equipment lifespan, reduce maintenance costs, and improve work efficiency. Furthermore, ceramic gaskets exhibit good chemical stability, resisting corrosion from most acids, alkalis, salts, and organic solvents, thus finding wide application in the chemical, petroleum, and metallurgical industries. The manufacturing process of ceramic gaskets generally includes raw material preparation, molding, and sintering steps; different process parameters and raw material ratios affect the performance and applications of the ceramic gasket.

[0003] In thin plate welding, ceramic backing is often used to support the back of the weld to achieve good shape. However, the existing installation method usually uses adhesive to fix it. Although this method can prevent the ceramic backing from shifting, it lacks sufficient clamping force, which makes the ceramic backing prone to slight floating during the welding process. It cannot fit tightly against the back of the weldment, thus affecting the shape and appearance of the weld and the welding quality. Utility Model Content

[0004] One objective of this invention is to provide a ceramic gasket clamping device for welding. This invention addresses the problem mentioned in the background that, in thin plate welding, ceramic gaskets are often used to support the back of the weld to achieve good shape. However, existing installation methods typically use adhesive fixation. While this method can prevent the ceramic gasket from shifting, it lacks sufficient clamping force, causing the ceramic gasket to easily float slightly during welding and fail to adhere tightly to the back of the weldment, thus affecting the aesthetics of the weld and the welding quality.

[0005] A ceramic gasket tightening device for welding according to an embodiment of the present invention includes:

[0006] The clamping mechanism is arranged in a rectangular shape with four sets, including a T-shaped seat. A first connecting plate and a second connecting plate are rotatably mounted on the top two sides of the T-shaped seat, respectively. A waist-shaped frame is fixedly mounted on one side of the second connecting plate. The waist-shaped frame is connected to the first connecting plate and the second connecting plate through a toggle component to achieve clamping and releasing movements. A support seat is provided at the bottom of the waist-shaped frame. The support seat is connected to the waist-shaped frame through an adjustable component to achieve lateral distance adjustment. A first rotating shaft is fixedly mounted at the front end of the support seat. An L-shaped top plate is rotatably mounted on the outer side of the first rotating shaft. A roller is rotatably mounted on one side of the L-shaped top plate through a second rotating shaft.

[0007] A fixing component, installed at the bottom of the T-shaped seat in the clamping mechanism, is used to clamp the weldment at the edge;

[0008] The telescopic mechanism, installed at the bottom of the lower L-shaped clamping plate in the fixed assembly, is used to allow for free adjustment according to the width of the weldment.

[0009] Preferably, the actuating component includes a bracket, the upper ends of the first connecting plate and the second connecting plate are both rotatably disposed inside the bracket, and a pressing element is fixedly disposed at the tail end of the bracket.

[0010] Preferably, the pressing element is wrapped with a flexible rubber pad on the outside.

[0011] Preferably, the adjustable component includes a first hand-tightening bolt threaded onto the top of the support base, and a compression washer sleeved on the outside of the first hand-tightening bolt.

[0012] Preferably, the compression pad is movably positioned at the top of the waist-shaped frame.

[0013] Preferably, there are two of each of the second rotating shaft and roller, and they are distributed at both ends of the L-shaped top plate.

[0014] Preferably, the fixing assembly includes an upper L-shaped clamping plate fixed to the bottom of the T-shaped seat and a lower L-shaped clamping plate movable at the bottom of the upper L-shaped clamping plate. A second hand-tightening bolt is rotatably provided on the top of the upper L-shaped clamping plate, and the threaded end of the second hand-tightening bolt is threadedly connected to the lower L-shaped clamping plate.

[0015] Preferably, the telescopic mechanism includes a telescopic frame fixed to the bottom of the lower L-shaped clamping plate and a telescopic arm movable between the two telescopic frames. The telescopic frame and the telescopic arm form a rectangular structure that can accommodate weldments of different widths.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problem of slight floating caused by insufficient clamping force in ceramic gaskets in the prior art through the setting of a clamping mechanism. In use, the operator presses the pressing part of the actuating component, which drives the first and second connecting plates of the bracket to rotate around the T-shaped seat, causing the waist-shaped frame to move downward, thereby pushing the rollers at the front end of the support seat and the L-shaped top plate to press against the ceramic gasket. At the same time, the lateral position of the support seat can be adjusted by the first hand-tightening bolt of the adjustable component, changing the contact distance between the rollers and the weldment, and achieving precise control of the clamping force. Therefore, the added clamping mechanism allows the ceramic gasket to fit tightly against the back of the weldment, avoiding slight floating and ensuring the stability of the ceramic gasket and the welding quality during the welding process.

[0018] This invention effectively avoids the problem of easy displacement of ceramic gaskets caused by adhesive fixing by setting a fixing component. In use, the upper L-shaped clamping plate and the lower L-shaped clamping plate are engaged at the edge of the weldment. Rotating the second hand-tightening bolt drives the lower L-shaped clamping plate to move upward along the thread, forming a clamping force with the upper L-shaped clamping plate, thereby firmly fixing the entire device to the edge of the weldment. Therefore, the correct position of the ceramic gasket is ensured, thus guaranteeing the accuracy and consistency of the weld.

[0019] This utility model effectively avoids the problem of ceramic pads not being able to fit due to changes in the width of the weldment by setting a telescopic mechanism. In use, according to the width requirements of the weldment, the telescopic arm can be manually stretched or contracted within the telescopic frame to adjust the spacing of the clamping mechanisms on both sides, so that the rollers act symmetrically on both ends of the ceramic pad. Then, it is fixed to the edge of the weldment by using a fixing component, thereby effectively improving the versatility and applicability of the ceramic pad clamping device for welding.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] refer to Figure 1-4 A ceramic gasket clamping device for welding, comprising:

[0028] The clamping mechanism 1 is arranged in a rectangular shape with four sets, including a T-shaped seat 101. A first connecting plate 102 and a second connecting plate 103 are rotatably mounted on the top two sides of the T-shaped seat 101, respectively. A waist-shaped frame 106 is fixedly mounted on one side of the second connecting plate 103. The waist-shaped frame 106 is connected to the first connecting plate 102 and the second connecting plate 103 via a toggle assembly to achieve clamping and releasing movements. The toggle assembly includes a bracket 104. The upper ends of the first connecting plate 102 and the second connecting plate 103 are rotatably mounted inside the bracket 104. A pressing element 105 is fixedly mounted at the tail end of the bracket 104. A support seat 109 is provided at the bottom of the waist-shaped frame 106. The support seat 109 is connected to the waist-shaped frame 106 via an adjustable component to achieve lateral distance adjustment. The adjustable component includes a threaded mounting bracket. A first hand-tightening bolt 107 is mounted on the top of the support base 109, and a compression washer 108 is sleeved on the outside of the first hand-tightening bolt 107. A first rotating shaft 110 is fixedly installed at the front end of the support base 109. An L-shaped top plate 111 is rotatably installed on the outside of the first rotating shaft 110. A roller 113 is rotatably installed on one side of the L-shaped top plate 111 via a second rotating shaft 112. In use, the operator presses the pressing part of the actuating component to drive the bracket to rotate the first connecting plate and the second connecting plate around the T-shaped seat, thereby driving the waist-shaped frame to move downward, and thus pushing the support base and the roller at the front end of the L-shaped top plate to press against the ceramic liner. At the same time, the lateral position of the support base can be adjusted by adjusting the first hand-tightening bolt of the adjustable component to change the contact distance between the roller and the weldment, thereby achieving precise control of the tightening force.

[0029] The fixing component 2 is installed at the bottom of the T-shaped seat 101 in the clamping mechanism 1 and is used to clamp the weldment at the edge. The fixing component 2 includes an upper L-shaped clamping plate 201 fixed to the bottom of the T-shaped seat 101 and a lower L-shaped clamping plate 202 movable at the bottom of the upper L-shaped clamping plate 201. A second hand-tightening bolt 203 is rotatably provided on the top of the upper L-shaped clamping plate 201. The threaded end of the second hand-tightening bolt 203 is threadedly connected to the lower L-shaped clamping plate 202. In use, the upper L-shaped clamping plate and the lower L-shaped clamping plate are engaged at the edge of the weldment. The second hand-tightening bolt is rotated to drive the lower L-shaped clamping plate to move upward along the thread, forming a clamping force with the upper L-shaped clamping plate, thereby firmly fixing the entire device to the edge of the weldment.

[0030] The telescopic mechanism 3 is installed at the bottom of the lower L-shaped clamping plate 202 in the fixing assembly 2. It is used to achieve free adjustment according to the width of the weldment. The telescopic mechanism 3 includes a telescopic frame 301 fixed to the bottom of the lower L-shaped clamping plate 202 and a telescopic arm 302 that moves between the two telescopic frames 301. The telescopic frame 301 and the telescopic arm 302 form a rectangular structure that can adapt to weldments of different widths. In use, according to the width requirements of the weldment, the position of the telescopic arm in the telescopic frame is manually stretched or contracted to adjust the spacing of the clamping mechanisms on both sides so that the rollers act symmetrically on both ends of the ceramic pad. Then, it is fixed to the edge of the weldment using the fixing assembly.

[0031] Example 1: The outer side of the pressing member 105 is wrapped with a flexible rubber pad. The flexible rubber pad can increase the comfort of the contact area between the pressing member 105 and the operator's hand and prevent slipping. The compression pad 108 is located on the top of the waist-shaped frame 106 and can be movably set. The compression pad can improve the stability of the support seat during fixation.

[0032] Example 2: Two second rotating shafts 112 and two rollers 113 are provided and distributed at both ends of the L-shaped top plate 111. The L-shaped top plate 111 can rotate more smoothly, further improving the stability and reliability of the clamping.

[0033] Working principle: In use, first, according to the width of the weldment, manually adjust the position of the telescopic arm 302 in the telescopic mechanism 3 within the telescopic frame 301 to change the spacing of the two clamping mechanisms 1, so that the rollers 113 act symmetrically on both ends of the ceramic gasket. After adjustment, engage the upper L-shaped clamping plate 201 and the lower L-shaped clamping plate 202 in the fixing assembly 2 with the edge of the weldment. Rotate the second hand-tightening bolt 203 in the fixing assembly 2 to drive the lower L-shaped clamping plate 202 to move upward along the thread, forming a clamping force with the upper L-shaped clamping plate 201, thereby firmly securing the entire device. Fixed to the edge of the weldment, the operator then drives the bracket 104 to rotate around the T-shaped seat 101 by pressing the pressing part 105 of the toggle component in the tightening mechanism 1, which in turn drives the first connecting plate 102 and the second connecting plate 103 to move downwards, thereby pushing the support seat 109 and the roller 113 at the front end of the L-shaped top plate 111 to press against the ceramic liner. The lateral position of the support seat 109 is adjusted by the first hand-tightening bolt 107 of the adjustable component in the tightening mechanism 1, changing the contact distance between the roller 113 and the weldment, thereby achieving precise control of the tightening force.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
