Description

Technical Field

[0001] This utility model relates to the field of technical equipment, and in particular to a welding fixture for a guide wheel assembly. Background Technology

[0002] With the rapid development of industrial automation and intelligence, the global manufacturing industry is undergoing an unprecedented and profound transformation. This transformation is not only reflected in the optimization of production processes and the improvement of production efficiency, but also profoundly affects product quality, cost control, and the competitive landscape of the entire industry. As an indispensable key link in the manufacturing industry, welding fixtures are becoming increasingly important, while also facing more stringent and diversified requirements.

[0003] Related technology can be found in Chinese Patent No. CN108747195B, which discloses a welding fixture, including a clamping device for clamping a pipe fitting welded to another pipe fitting at one end; a guide for driving the clamping device to move along the axial direction of the clamped pipe fitting; and a power device for driving the clamping device to rotate. The rotation of the clamping device and its movement along the axial direction of the clamped pipe fitting form a compound motion. The trajectory of this compound motion is a reverse intersection line arranged offset from the intersection line, ensuring that any point on the intersection line always passes through the welding position during the motion. This invention utilizes a motor to drive rotation and a guide groove to generate a motion trajectory opposite to the intersection line, causing the two motion trajectories to cancel each other out. Ultimately, the compound motion trajectory always lies on a circle, allowing welding to be completed without moving the welding torch. The entire fixture structure is relatively simple, with low cost, and can effectively improve welding efficiency.

[0004] Regarding the aforementioned technologies, this welding method can only perform welding operations in preset or specific areas, and cannot be easily adapted to or switched to other non-designated areas. This greatly weakens its applicability in complex welding tasks, resulting in poor flexibility in the welding process and making it difficult to meet the diverse needs of industrial production. Utility Model Content

[0005] To improve the flexibility of welding fixtures, this application provides a welding fixture for guide wheel assemblies.

[0006] This application provides a welding fixture for a guide wheel assembly, which adopts the following technical solution:

[0007] A welding fixture for guide wheel assembly includes a base. The upper end of the base has a lifting plate that slides vertically. The lower end of the lifting plate has a cylinder for pushing the lifting plate to slide vertically. A fixing plate is fixed to the upper end of the lifting plate, and a motor is fixed to the lower end of the fixing plate. The motor is vertically positioned. A second motor, corresponding to the first motor, is fixed to the upper end of the fixing plate. A connecting block is fixed to the output shaft of the first motor. The connecting block is horizontally positioned and has a groove along its length. A slider is located within the groove and is slidably connected to the connecting block along the length of the groove. A connecting rod is horizontally fixed to the output end of the second motor. A second connecting rod is laterally hinged to the end of the first connecting rod away from the second motor, and the end of the second connecting rod opposite to the first connecting rod is hinged to the slider. A welding torch is located at the lower end of the slider. Three sets of clamping assemblies are fixed to the upper end of the base. A support portion for placing the guide wheel assembly is located below the welding torch. The three sets of clamping assemblies are evenly arranged around the support portion to clamp and position the guide wheel assembly on the support portion.

[0008] By adopting the above technical solution, when welding the guide wheel assembly, the guide wheel assembly is placed on the support part, and the clamping assembly clamps the guide wheel assembly. When the cylinder is started, the cylinder drives the lifting plate to rise and fall, which in turn drives the fixed plate to rise and fall. The fixed plate then drives the motor to rise and fall, which in turn drives the slider to rise and fall, further realizing the raising and lowering of the welding torch and adjusting the distance between the welding torch and the guide wheel assembly. When the motor is started, it drives the connecting block to rotate, which in turn drives the slider to rotate, which in turn drives the welding torch to rotate, facilitating the adjustment of the welding torch position. When the motor is started, it drives the connecting rod to move, which in turn drives the connecting rod to move, which in turn drives the slider to slide along the length of the groove, realizing the extension and retraction of the welding torch, which is beneficial for adjusting the welding torch position and improving the flexibility of the welding fixture.

[0009] Optionally, the support unit includes a motor three, a gear one, a gear two, a slide rod, and a threaded rod. The motor three is fixed to the lower end of the base, the gear one is fixed to the output shaft of the motor three, the gear two is located at the upper end of the base, the gear two meshes with the gear one, the threaded rod passes through the gear two in the vertical direction and is threadedly connected to the gear two, the slide rod is fixed parallel to the threaded rod, and the slide rod passes through the base in the length direction and is slidably connected to the base, and a placement plate is fixed at the upper end of the threaded rod for placing the guide wheel assembly.

[0010] By adopting the above technical solution, motor three is started, which drives gear one to rotate. Gear one rotates, which drives gear two to rotate. The base limits the threaded rod through the slide rod, so that when gear two rotates, it drives the threaded rod to move vertically, thereby realizing the lifting and lowering of the placement plate. The placement plate is used to support the guide wheel assembly. When the guide wheel assembly does not need the support of the placement plate, the placement plate descends.

[0011] Optionally, the clamping assembly includes a second cylinder, a connecting rod, and a push block. The second cylinder is fixed to the upper end of the base, the connecting rod is fixed to the output end of the second cylinder, the push block is located at the end of the connecting rod away from the second cylinder, and the push block is fixedly connected to the connecting rod. The push block is provided with a clamping element for clamping the guide wheel assembly.

[0012] By adopting the above technical solution, when the guide wheel assembly is clamped, cylinder two is activated. The activation of cylinder two drives the connecting rod to move closer to the placement plate, which in turn drives the push block to move closer to the placement plate, thus clamping the guide wheel assembly.

[0013] Optionally, the push block has an arc-shaped surface that is adapted to the side wall of the guide wheel.

[0014] By adopting the above technical solution, the arc-shaped surface design allows the push block to fit closely against the side wall of the guide wheel, which helps to improve the stability of the clamping assembly in clamping the guide wheel.

[0015] Optionally, the clamping component includes an upper clamping plate and a lower clamping plate. The lower clamping plate is fixed to the lower end of the push block, and the upper clamping plate is located at the upper end of the push block. The upper clamping plate is slidably connected to the push block in a vertical direction. A screw is provided at the upper end of the upper clamping plate. The screw passes through the upper clamping plate and is fixedly connected to the lower clamping plate. A nut is provided on the side of the upper clamping plate away from the lower clamping plate. The nut is threadedly connected to the screw.

[0016] By adopting the above technical solution, when the guide wheel assembly and the push block come into contact, the upper clamping plate and the lower clamping plate clamp the side wall of the guide wheel assembly. By rotating the nut, the upper clamping plate moves closer to the lower clamping plate, thereby improving the stability of the upper clamping plate and the lower clamping plate in clamping the guide wheel assembly.

[0017] Optionally, a fixed block is provided at the end of the slider away from the motor. A pushing block is provided inside the fixed block. The pushing block is rotatably connected to the fixed block and slides with the fixed block in the horizontal direction. The pushing block passes through the fixed block and is fixedly connected to the welding gun. Several grooves are provided on the side wall of the fixed block. The grooves are evenly distributed around the circumference of the fixed block. A protrusion is fixed on the side wall of the pushing block. The protrusion is located in any groove and fits against the inner wall of the groove. An elastic element is fixed between the fixed block and the pushing block. The elastic element is used to push the protrusion into the groove.

[0018] By adopting the above technical solution, when it is necessary to adjust the welding gun angle, press the push block towards the fixed block to separate the protrusion from the groove, rotate the push block to adjust the welding gun angle, and after the adjustment is completed, release the push block. Under the action of the elastic element, the protrusion moves closer to the groove, so that the groove locks the protrusion, thereby improving the flexibility of the welding gun fixture.

[0019] Optionally, a baffle is provided at the lower end of the fixing block, and the baffle is slidably connected to the fixing block in the lateral direction.

[0020] By adopting the above technical solution, the baffle locks the push block, keeping the protrusion and groove locked together, reducing the probability of the welding torch angle moving.

[0021] Optionally, a motor is fixedly mounted at the lower end of the slider, a turntable is fixedly mounted on the output shaft of the motor, a disc is fixedly mounted at the upper end of the fixed block, the disc is rotatably connected to the slider, and a rotating rod is provided on the side of the disc away from the fixed plate. A belt is provided between the rotating rod and the turntable, and both the rotating rod and the turntable are tumblingly connected to the belt.

[0022] By adopting the above technical solution, motor four is started, which drives the turntable to rotate. The rotation of the turntable drives the belt to rotate, which drives the rotating rod to rotate. The rotation of the rotating rod drives the disc to rotate, which drives the fixed block to rotate. The rotation of the fixed block drives the pushing block to rotate, thereby further realizing the adjustment of the welding gun angle and improving the flexibility of the welding fixture.

[0023] In summary, this application includes at least one of the following beneficial technical effects of the guide wheel assembly welding fixture:

[0024] 1. When motor one starts, it drives the connecting block to rotate. The rotation of the connecting block drives the slider to rotate. The rotation of the slider drives the welding gun to rotate, which is beneficial for adjusting the position of the welding gun. When motor two starts, it drives the connecting rod one to move. The movement of connecting rod one drives the movement of connecting rod two to move. The movement of connecting rod two drives the slider to slide along the length of the groove, realizing the extension and retraction of the welding gun. This is beneficial for adjusting the position of the welding gun and improving the flexibility of the welding fixture.

[0025] 2. When the guide wheel assembly and the push block come into contact, the upper clamping plate and the lower clamping plate clamp the side wall of the guide wheel assembly. Rotate the nut to move the upper clamping plate closer to the lower clamping plate, thereby improving the stability of the upper clamping plate and the lower clamping plate in clamping the guide wheel assembly.

[0026] 3. The baffle holds the push block in place, keeping the protrusion and groove engaged and reducing the probability of the welding torch shifting. Attached Figure Description

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.

[0033] This application discloses a welding fixture for a guide wheel assembly. Example

[0034] Reference Figure 1 and Figure 2 A welding fixture for a guide wheel assembly includes a base 1. The upper end of the base 1 has a support for placing the guide wheel assembly. The support includes a motor 12, a gear 121, a gear 122, a slide rod 124, and a threaded rod 123. The motor 12 is fixed to the lower end of the base 1. The gear 121 is fixed to the output shaft of the motor 12. When the motor 12 is started, it drives the gear 121 to rotate. The gear 122 is located at the upper end of the base 1 and meshes with the gear 121. Rotation of the gear 121 drives rotation of the gear 122. The threaded rod 123 passes vertically through the gear 122. The threaded rod 123 is threadedly connected to the gear 122. The sliding rod 124 is fixed parallel to the threaded rod 123 and passes through the base 1 along its length and is slidably connected to the base 1. The base 1 limits the threaded rod 123 through the sliding rod 124, so that when the gear 122 rotates, it drives the threaded rod 123 to move vertically. The upper end of the threaded rod 123 is fixed with a placement plate 125 for placing the guide wheel assembly. The vertical movement of the threaded rod 123 further realizes the lifting and lowering of the placement plate 125. When the placement plate 125 is not needed to support the guide wheel assembly, the placement plate 125 is lowered, improving the convenience of using the welding fixture.

[0035] Reference Figure 1 and Figure 3Three sets of clamping assemblies are fixedly installed on the upper end of the base 1. These three sets of clamping assemblies are evenly arranged around the circumference of the support section and are used to weld the guide wheel assembly on the support section. Each clamping assembly includes a second cylinder 13, a connecting rod 131, and a push block 132. The second cylinder 13 is fixedly installed on the upper end of the base 1. The connecting rod 131 is located at the output end of the second cylinder 13. When the second cylinder 13 is activated, it drives the connecting rod 131 to move. The connecting rod 131 is fixedly connected to the output end of the second cylinder 13. The push block 132 is located at the end of the connecting rod 131 opposite to the second cylinder 13, and is rotatably connected to the connecting rod 131. Movement of the connecting rod 131 drives movement of the push block 132, causing the push block 132 to clamp the guide wheel assembly. The push block 132 has an arc-shaped surface that adapts to the side wall of the guide wheel assembly, allowing the push block 132 to fit tightly against the side wall of the guide wheel assembly, which helps improve the stability of the clamping assembly in clamping the guide wheel assembly.

[0036] Reference Figure 1 and Figure 3 The push block 132 is equipped with a clamping component, which includes an upper clamping plate 133 and a lower clamping plate 134. The lower clamping plate 134 is fixed to the lower end of the push block 132, and the upper clamping plate 133 is located at the upper end of the push block 132. The upper clamping plate 133 slides vertically with the push block 132. When the guide wheel assembly contacts the push block 132, the guide wheel assembly is positioned between the upper clamping plate 133 and the lower clamping plate 134. The upper end of the upper clamping plate 133 is equipped with a screw 135. 135 passes through the upper clamping plate 133 and is fixedly connected to the lower clamping plate 134. The upper clamping plate 133 is provided with a nut 136 on the side away from the lower clamping plate 134. The nut 136 is threadedly connected to the screw 135. Rotating the nut 136 causes the upper clamping plate 133 to move closer to the lower clamping plate 134. At this time, the upper clamping plate 133 and the lower clamping plate 134 cooperate to clamp the guide wheel assembly, thereby improving the stability of the upper clamping plate 133 and the lower clamping plate 134 in clamping the guide wheel assembly.

[0037] Reference Figure 1 The upper end of the base 1 is provided with a lifting plate 111, which slides vertically. The lower end of the lifting plate 111 is provided with a cylinder 11, which is used to push the lifting plate 111 to slide vertically. When the cylinder 111 is activated, it drives the lifting plate 111 to rise and fall. The upper end of the lifting plate 111 is fixed with a fixing plate 112, which drives the fixing plate 112 to rise and fall. The lower end of the fixing plate 112 is fixed with a motor 113, which is set vertically. The upper end of the fixing plate 112 is fixed with a motor 114 corresponding to the motor 113, which drives the motor 113 and the motor 114 to rise and fall.

[0038] Reference Figure 1A connecting block 1131 is fixedly installed at the output end of motor 113. When motor 113 starts, it drives the connecting block 1131 to rotate. The connecting block 1131 is horizontally positioned and has a groove 1132 along its length. A slider 1133 is provided on the connecting block 1131. The slider 1133 is located in the groove 1132 and is slidably connected to the connecting block 1131 along the length of the groove 1132. The rotation of the connecting block 1131 drives the slider 1133 to rotate. A welding torch 115 is provided at the lower end of the slider 1133. The rotation of the slider 1133 drives the welding torch 115 to rotate. The output end of motor 2 114 is horizontally fixed with connecting rod 1141. The rotation of motor 2 114 drives the rotation of connecting rod 1141. The end of connecting rod 1141 away from motor 2 114 is connected to connecting rod 2 1142 in a transverse direction. The rotation of connecting rod 1141 drives the movement of connecting rod 2 1142. The end of connecting rod 2 1142 away from connecting rod 1141 is hinged to slider 1133. The movement of connecting rod 2 1142 drives slider 1133 to slide along the length of slide groove 1132, realizing the extension and retraction of welding torch 115. This is beneficial for adjusting the position of welding torch 115 and improving the flexibility of welding fixture.

[0039] Reference Figure 1 and Figure 4 A fixed block 1143 is provided at the end of the slider 1133 away from the motor 113. A pushing block 1144 is provided inside the fixed block 1143. The pushing block 1144 is rotatably connected to the fixed block 1143, and the pushing block 1144 and the fixed block 1143 slide in the horizontal direction. The pushing block 1144 passes through the fixed block 1143 and is fixedly connected to the welding torch 115. Several grooves 1146 are provided on the side wall of the fixed block 1143, and a protrusion 1145 is fixedly provided on the side wall of the pushing block 1144. The protrusion 1145 is located in the groove 1146 and close to the fixed block 1145. Pressing the push block 1144 in the direction of the fixed block 1143 separates the protrusion 1145 from the groove 1146. Rotating the push block 1144 adjusts the angle of the welding torch 115. An elastic element 1148 is fixed between the fixed block 1143 and the push block 1144. After adjusting the angle of the welding torch 115, the push block 1144 is released. Under the action of the elastic element 1148, the protrusion 1145 moves closer to the groove 1146, causing the groove 1146 to lock the protrusion 1145. This helps to fix the angle of the welding torch 115 and improves the flexibility of the welding torch 115 fixture. A baffle 1147 is provided at the lower end of the fixed block 1143. The baffle 1147 is slidably connected to the fixed block 1143 in the lateral direction. The baffle 1147 locks the push block 1144, keeping the protrusion 1145 locked with the groove 1146, reducing the probability of the welding torch 115 angle moving.

[0040] Reference Figure 4A motor 1134 is fixedly mounted at the lower end of the slider 1133. A turntable 1135 is fixedly mounted on the output shaft of the motor 1134. When the motor 1134 is started, it drives the turntable 1135 to rotate. A disc 1137 is fixedly mounted at the upper end of the fixed block 1143. A rotating rod 1138 is provided on the side of the disc 1137 away from the fixed plate 112. A belt 1136 is provided between the rotating rod 1138 and the turntable 1135. The rotating rod 1138 and the turntable 1135 are both rolledly connected to the belt 1136. The rotation of the turntable 1135 drives the belt 1136 to rotate. The rotation of the belt 1136 drives the rotating rod 1138 to rotate. The rotation of the rotating rod 1138 drives the disc 1137 to rotate. The rotation of the disc 1137 drives the fixed block 1143 to rotate. The rotation of the fixed block 1143 drives the push block 1144 to rotate, further realizing the adjustment of the angle of the welding gun 115 and improving the flexibility of the welding fixture.

[0041] The implementation principle of the guide wheel assembly welding fixture in this application embodiment is as follows: When welding the guide wheel assembly is required, the guide wheel assembly is placed on the placement plate 125, the cylinder 2 13 clamping assembly is activated to clamp the guide wheel assembly, the nut 136 is rotated to make the clamping more stable, the cylinder 2 13 is activated to adjust the height of the welding gun 115, the motor 1 113 and the motor 2 114 are activated to adjust the position of the welding gun 115, and the push block 1144 is pressed to adjust the angle of the welding gun 115, thereby realizing the adjustment of the position and angle of the welding gun 115 and improving the flexibility of the welding fixture.
