Description

Technical Field

[0001] This utility model relates to the field of welding robotic arm technology, and in particular to a multi-station industrial welding robotic arm with adjustable angle. Background Technology

[0002] A multi-station industrial welding robotic arm is an automated device specifically designed for industrial welding scenarios. It has the ability to perform welding tasks at multiple work positions (stations). These robotic arms are typically mounted on a fixed base platform and, through their flexible mechanical structure and precise motion control system, can quickly and accurately switch between different work positions to adapt to the needs of different workpieces or welding parts.

[0003] Some existing robotic arms lack effective limiting mechanisms. During the welding process, the rotating seat may rotate or shift due to welding vibration, external forces generated by the robotic arm's own movement, etc., resulting in decreased welding accuracy and welding defects such as uneven welds and porosity. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-angle, multi-station industrial welding robotic arm. This device improves the stability of the welding robotic arm, thus solving the problem of poor stability in existing welding robotic arms.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-angle, multi-station industrial welding robotic arm includes a base, the side wall of which has multiple slots, a clamping block slidably connected inside the slots, a connecting seat fixedly connected to the side wall of the clamping block, a ring plate slidably connected to the side wall of the base, multiple connecting blocks fixedly connected to the side wall of the ring plate, and an inclined plate hinged between the inside of the connecting block and the inner wall of the connecting seat; and a rotating base, which is rotatably mounted on the upper end of the base, with the welding robotic arm fixedly connected to the upper end of the rotating base.

[0007] Preferably, a motor is fixedly connected inside the base, and a gear is fixedly connected to the output end of the motor.

[0008] Preferably, the lower end of the rotary base is provided with a groove, and multiple tooth blocks are fixedly connected to the inner wall of the groove, and the multiple tooth blocks are distributed in a circular array.

[0009] Preferably, both the motor and the gear are located inside the groove, and the tooth block engages with the gear.

[0010] Preferably, both sides of the base are fixedly connected with protrusions, and the protrusions are provided with through grooves.

[0011] Preferably, mounting bases are fixedly connected to both sides of the base, and electric actuators are fixedly connected inside the mounting bases. The output end of the electric actuators is fixedly connected to the lower end of the ring plate.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The motor drives the gears to rotate, and the gears and gear blocks work together to achieve rapid rotation of the rotating base and welding robot arm. This allows the welding robot arm to be quickly moved to the target workstation, reducing waiting time and enabling welding work to start faster, thereby improving overall production efficiency. At the same time, the welding robot arm can work continuously between different workstations. When the workpiece at one workstation is ready for welding, the robot arm can quickly switch to that workstation for welding without waiting for other equipment or manual intervention, which greatly improves the continuity and smoothness of the production line and effectively shortens the production cycle.

[0014] 2. By using multiple clamping blocks to hold and limit the rotatable base, it can effectively resist the vibration generated during welding and the movement of the robotic arm itself during the operation of the welding robot. This prevents the rotatable base from rotating or shifting during the welding process, ensuring that the welding robot is always in a stable working state, thereby guaranteeing the accuracy and quality of the welding.

A ring plate 106 is slidably connected to the sidewall of the base 001. Multiple connecting blocks 107 are fixedly connected to the sidewall of the ring plate 106. An inclined plate 108 is hinged between the inside of each connecting block 107 and the inner wall of the connecting seat 105. A rotating base 002 is rotatably mounted on the upper end of the base 001. A welding robotic arm 203 is fixedly connected to the upper end of the rotating base 002. The operator moves the base 001 to a designated position among the multiple stations, and then... The rotary table 002 rotates horizontally, rotating the welding robot arm 203 to one side of a station where a workpiece is fixed. Then, the ring plate 106 slides upward longitudinally. The ring plate 106 pushes the inclined plate 108 to gradually tilt and rotate through the connecting block 107. At the same time, the inclined plate 108 pushes the clamping block 104 to slide inside the slot 103. The clamping block 104 slides out from inside the slot 103, and the side wall of the clamping block 104 is in contact with the side wall of the rotary table 002. The rotary table 002 is clamped and limited by multiple clamping blocks 104 to prevent the rotary table 002 from rotating when the welding robot arm 203 is operating. Then, the welding robot arm 203 is used to weld the workpiece fixed at the upper end of one of the stations.

[0023] A motor 101 is fixedly connected inside the base 001. A gear 102 is fixedly connected to the output end of the motor 101. The gear 102 is a spur gear and is driven to rotate by the output end of the motor 101.

[0024] The lower end of the rotary seat 002 is provided with a groove 201, and multiple tooth blocks 202 are fixedly connected to the inner wall of the groove 201. The multiple tooth blocks 202 are distributed in a circular array, and the tooth blocks 202 are straight tooth blocks.

[0025] Both the motor 101 and the gear 102 are located inside the groove 201. The tooth block 202 and the gear 102 cooperate. When the gear 102 rotates, the rotary seat 002 rotates horizontally through the cooperation between the tooth block 202 and the gear 102.

[0026] Both sides of the base 001 are fixedly connected with protrusions 109. The protrusions 109 have through grooves. The operator inserts expansion bolts through the through grooves inside the protrusions 109 to fix the protrusions 109.

[0027] Both sides of the base 001 are fixedly connected to mounting bases 110. An electric push rod 111 is fixedly connected inside the mounting base 110. The output end of the electric push rod 111 is fixedly connected to the lower end of the ring plate 106. The ring plate 106 is pushed or pulled longitudinally by the output end of the electric push rod 111. A controller is fixedly connected inside the base 001. An angle sensor is horizontally installed inside the rotary base 002. The controller is electrically connected to the angle sensor, the motor 101 and the electric push rod 111 respectively. Through the pre-set program inside the controller and the real-time monitoring of the angle sensor, the motor 101 and the electric push rod 111 are coordinated and controlled.

[0028] In this utility model, the operator moves the base 001 to a designated position among multiple workstations, and then inserts an expansion bolt through the internal groove of the protrusion 109 to fix the protrusion 109 and fix the base 001 in the designated position.

[0029] The output of motor 101 drives gear 102 to rotate, and the gear block 202 and gear 102 cooperate to make the rotating base 002 rotate horizontally. At the same time, the rotating base 002 drives the welding robot arm 203 to rotate, and rotates the welding robot arm 203 to one side of one of the workstations where the workpiece is fixed.

[0030] The output end of the electric actuator 111 pushes the ring plate 106 to slide longitudinally upwards. The ring plate 106 pushes the inclined plate 108 to gradually tilt and rotate through the connecting block 107. At the same time, the inclined plate 108 pushes the clamping block 104 to slide inside the slot 103. The clamping block 104 slides out from inside the slot 103, and the side wall of the clamping block 104 is in close contact with the side wall of the rotary seat 002. The rotary seat 002 is clamped and limited by multiple clamping blocks 104 to prevent the rotary seat 002 from rotating when the welding robot arm 203 is operating. Then, the welding robot arm 203 operates to weld the workpiece fixed at the upper end of one of the workstations.
