Technical Field

[0001] This utility model relates to the technical field of welding gripping devices, specifically an auxiliary gripping device for welding production lines. Background Technology

[0002] A welding production line is an automated or semi-automated production system used for welding operations, primarily in the metal processing and manufacturing industries. It integrates multiple welding stations or welding equipment in a specific sequence and process, completing the welding work through mechanized or automated means. A welding production line typically includes multiple workstations and supporting equipment such as welding machines, robots, feeding systems, and cooling systems, enabling efficient and large-scale production.

[0003] For example, an auxiliary gripping device for a welding production line, disclosed in CN223098320U, includes a crossbeam. Synchronous sliding trolleys are fixedly connected to both ends of the crossbeam. A transverse trolley is slidably mounted on the crossbeam. A rotating seat is fixedly mounted below the transverse trolley. An electric telescopic rod is fixedly mounted below the rotating seat. A mounting block is fixedly mounted at the telescopic end of the electric telescopic rod. A rocker arm is hinged to the bottom of the mounting block, and a rocker arm is hinged to the bottom of the rocker arm. A connector is rotatably connected to the rocker arm, and a gripping head is detachably connected to the connector. The movable synchronous sliding trolley, the transverse trolley, the telescopic electric telescopic rod, the swingable rocker arm, the rocker arm, the rotating seat, and the connector improve the flexibility of the gripping head and increase its applicability.

[0004] The aforementioned patent proposes that a gripping head is detachably connected to the plug-in base. The flexibility of the gripping head is improved by a movable synchronous sliding trolley, a transverse trolley, a retractable electric telescopic rod, a swinging rocker arm, a rotating base, and a plug-in base. However, in actual use, the high hardness of the welding slag will accelerate wear when the surface of the gripping head comes into direct contact with the welded material, leading to a decrease in gripping accuracy or deformation of the parts, which will affect the performance of the gripping head. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary gripping device for welding production lines, in order to solve the problem mentioned in the background art that when the gripping head surface comes into direct contact with the workpiece, it will accelerate wear, leading to a decrease in gripping accuracy or deformation of the parts.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary gripping device for a welding production line, comprising a gripper, a cylinder bracket mounted on the top of the gripper, a threaded rod drive device mounted on the rear end of the cylinder bracket, a cross frame mounted on the rear end of the threaded rod drive device, a movable frame mounted between the two sides of the bottom end of the cross frame, a lead screw device mounted on the bottom end of the movable frame, a welding table mounted on the top of the lead screw device, and the welding table being located at the lower end of the gripper; pulley frames are mounted on both sides of the top end of the lead screw device. The gripper includes an operating shell and a bottom block installed at the bottom of the operating shell. A positioning tube is installed in the middle of the operating shell and the bottom block, and gripping clamps are installed on both sides of the bottom of the operating shell.

[0007] Preferably, the gripper has side plates installed on both sides of its bottom end, and the side plates and gripper have vertically formed Z-shaped holes inside.

[0008] Preferably, a movable plate is installed on one side of the movable end of the cylinder bracket, an inverted T-shaped tube is embedded in the middle of the movable plate, an air pump is installed at the top of the inverted T-shaped tube, and a T-shaped tube is installed on both sides of the lower end of the inverted T-shaped tube, with air pipes installed at both ends of the T-shaped tube.

[0009] Preferably, a base plate is installed on one side of the bottom of the movable plate, a drive cylinder is installed on the top of the base plate, the moving end of the drive cylinder passes through the middle of the base plate, and a connector is installed at the bottom of the drive cylinder.

[0010] Preferably, a movable tube is installed inside the positioning tube, and an inner circular plate is installed at the top of the movable tube.

[0011] Preferably, an inner groove is provided on the side of the lower end of the gripper that is close to it, and heat dissipation holes are provided on the outer surface of the gripper. A rubber strip is also installed inside the inner groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The present invention discloses an auxiliary gripping device for a welding production line. When the gripper is at the top of the workpiece, the air pump operates. When the gripper is at the top of the workpiece, the air pump draws air into the interior of the inverted T-shaped tube. The air is then diverted by the three-way pipes installed on both sides of the moving plate. The air flow is used to clean some of the welding slag on the surface of the workpiece. The air is also used to cool the surface of the workpiece, so as to avoid the high temperature and welding slag affecting the gripping effect of the gripper on the workpiece.

[0013] 2. The present invention discloses an auxiliary gripping device for a welding production line. When the gripper is to grip the workpiece, the moving end of the drive cylinder moves downward inside the bottom block, and the two sets of gripping clamps will move closer to each other. Another part of the air will cool the two sides of the workpiece through the heat dissipation holes, that is, cool the gripping position of the gripper on the workpiece. When the rubber strip installed inside the inner groove comes into contact with the surface of the workpiece, the welding slag still on the surface of the workpiece will cause the rubber strip to deform. At the same time, the cooled workpiece will not affect the elasticity of the rubber strip, thus avoiding the welding slag from affecting the gripping effect of the gripper.

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.

[0017] Example 1: Please refer to Figures 1-4An auxiliary gripping device for a welding production line includes a gripper 8, a cylinder bracket 7 mounted on the top of the gripper 8, a threaded rod drive device 6 mounted on the rear end of the cylinder bracket 7, a cross frame 5 mounted on the rear end of the threaded rod drive device 6, a movable frame 3 mounted between the two sides of the bottom end of the cross frame 5, a lead screw device 1 mounted on the bottom end of the movable frame 3, a welding table 2 mounted on the top of the lead screw device 1 and located at the lower end of the gripper 8, and pulley frames 4 mounted on both sides of the top of the lead screw device 1 and located inside the bottom end of the movable frame 3; the working principle of the lead screw device 1 and the threaded rod drive device 6 is that when the motor drives the threaded rod to rotate, the helix of the threaded rod will force the mating connecting parts to move along the axis of the threaded rod, which facilitates the adjustment of the gripping position.

[0018] The gripper 8 includes an operating housing 81 and a bottom block 83 installed at the bottom of the operating housing 81. A positioning tube 82 is installed in the middle of the operating housing 81 and the bottom block 83. Gripping clamps 84 are installed on both sides of the bottom of the operating housing 81.

[0019] Side plates 85 are installed on both sides of the bottom end of the gripper 84. Z-shaped holes 89 are vertically opened inside the side plates 85 and the gripper 84. The Z-shaped holes 89 facilitate the diversion of air.

[0020] A movable plate 71 is installed on one side of the movable end of the cylinder bracket 7. An inverted T-shaped tube 72 is embedded in the middle of the movable plate 71. An air pump 78 is installed at the top of the inverted T-shaped tube 72. A three-way tube 73 is installed on both sides of the lower end of the inverted T-shaped tube 72. An air pipe 74 is installed at both ends of the three-way tube 73. The bottom end of the air pipe 74 is installed inside the top of the Z-shaped hole 89.

[0021] In this embodiment: the cross frame 5, the threaded rod drive device 6, the cylinder bracket 7, and the clamp 8 are installed at the top of the movable frame 3. The clamp 8 is located at the top of the welding table 2. After the welding of the workpiece at the top of the welding table 2 is completed, the screw device 1 drives the movable frame 3 to move above the welding table 2. The movable frame 3 slides at the top of the pulley frame 4. The threaded rod drive device 6 controls the cylinder bracket 7 and the clamp 8 to move above the workpiece. When the clamp 8 is at the top of the workpiece, the air pump 78 operates. When the clamp 8 is at the top of the workpiece, the air pump 78 draws air into the inverted T-shaped tube 72. The air is then split by the three-way tubes 73 installed on both sides of the moving plate 71 and discharged into the Z-shaped hole 89 at the top of the side plate 85 through the air pipe 74. A portion of the air is discharged from the bottom of the Z-shaped hole 89. The airflow is used to clean some of the welding slag on the surface of the workpiece and also to cool the surface of the workpiece, so as to avoid the high temperature and welding slag affecting the gripping effect of the clamp 84 on the workpiece.

[0022] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 A base plate 75 is installed on one side of the bottom of the movable plate 71, and a drive cylinder 76 is installed on the top of the base plate 75. The moving end of the drive cylinder 76 passes through the middle of the base plate 75, and a connector 77 is installed at the bottom of the drive cylinder 76. The drive cylinder 76 is designed to facilitate the adjustment of the state of the gripper 84.

[0023] The positioning tube 82 has a moving tube 821 installed inside. The top of the moving tube 821 has an inner circular plate 822 installed. The inner circular plate 822 is adapted to the inside of the positioning tube 82. The diameter of the inner circular plate 822 is smaller than the diameter of the moving tube 821. The bottom end of the moving tube 821 is installed through the middle of the top of the gripping clamp 84.

[0024] An inner groove 86 is provided on one side of the lower end of the gripper 84, and a heat dissipation hole 87 is provided on the outer surface of the gripper 84. A rubber strip 88 is also installed inside the inner groove 86. The heat dissipation hole 87 communicates with the interior of the Z-shaped hole 89. The position of the inner groove 86 is offset from the position of the heat dissipation hole 87.

[0025] In this embodiment: when the gripper 8 is to grip the workpiece, the moving end of the drive cylinder 76 drives the inner circular plate 822 and the moving tube 821 to move downward inside the bottom block 83 through the connector 77. The gripping clamps 84, which are movably installed on both sides of the bottom of the operating shell 81, will move closer to each other. Another part of the air will cool the two sides of the workpiece through the heat dissipation hole 87, that is, cool the gripping position of the gripping clamp 84 on the workpiece. When the rubber strip 88 installed inside the inner groove 86 comes into contact with the surface of the workpiece, the welding slag still on the surface of the workpiece will cause the rubber strip 88 to deform. At the same time, the cooled workpiece will not affect the elasticity of the rubber strip 88, thus avoiding the welding slag from affecting the gripping effect of the gripper 8.
