Description

Technical Field

[0001] This utility model relates to the field of positioner technology, and more specifically, to a high-load positioner structure. Background Technology

[0002] Ordinary positioners are placed directly on the ground alongside welding equipment such as robots. However, this can sometimes be problematic due to limited workshop space, long welding times, and wire feeding tube entanglement. Adopting a high-load positioner structure can avoid these issues, which necessitates a high-load positioner structure.

[0003] In existing publicly available literature, patent publication number CN216178019U discloses a horizontal positioner for coordinated operation of dual welding arms. This positioner effectively protects the operator. The horizontal positioner for coordinated operation of dual welding arms comprises: a base assembly, a table rotation support device, a tabletop, a partition, and a robotic welding device. Its key feature is that the table rotation support device is connected to the upper front end of the base assembly, and the robotic welding device is connected to the upper rear sides. However, this positioner still has the following problems.

[0004] When a positioner is used for high-load positioning, the mechanical workpiece is relatively heavy, making it difficult to achieve high-load positioning with the specified rotational force. This results in slow high-load movement or even poor high-load positioning effect. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a high-load positioner structure, comprising a support plate, a support platform, and a robotic arm. The support platform is fixed to the upper surface of the support plate, and the robotic arm is fixed to one side of the support platform. A dual positioner mechanism is installed at the top of the robotic arm. The dual positioner mechanism includes a positioner bracket fixedly mounted at the top of the robotic arm, and a positioner motor is fixedly connected to the top of the positioner bracket. A positioner shaft is fixedly mounted at the output end of the positioner motor. An auxiliary motor is fixedly connected to one end of the positioner shaft, and a reinforcing frame is fixedly mounted on the lower surface of the auxiliary motor. A reinforcing support is fixedly mounted on one side of the reinforcing frame.

[0006] Preferably, the output end of the positioning motor is coaxially arranged with the positioning shaft. The positioning motor drives the positioning shaft to rotate, and the auxiliary motor also drives the positioning shaft to rotate. The reinforcing support is fixedly connected to the support plate, and the support plate supports the reinforcing support and the support platform. A positioning plate is fixedly installed on the bottom of the outer wall of the positioning shaft, and a positioning hole is formed on the inner wall of the positioning plate. An electric cylinder is fixedly installed on one side of the positioning plate, and a pressure plate is fixedly connected to the output end of the electric cylinder. The vertical cross-sectional shape of the positioning hole is circular, and the pressure plate is slidably connected to the positioning plate.

[0007] In use, this technology provides support to the support platform through the support plate, the robotic arm supports the displacement bracket, the reinforcement platform supports the reinforcement frame, and then the workpiece is inserted into the positioning hole inside the positioning plate. The pressure plate is pushed by the electric cylinder, so that the workpiece can be fixed inside the positioning plate. The displacement motor drives the displacement shaft to rotate, and the auxiliary motor drives the displacement shaft to assist in the rotation. In this way, the displacement shaft can make the positioning plate rotate under high load.

[0008] Preferably, a reinforcing mechanism is installed on one side of the support plate; the reinforcing mechanism includes multiple support blocks fixedly disposed on one side of the support plate; a base is fixedly connected to the bottom end of the support plate, a fixing seat is welded to the bottom end of the base, and a supporting base plate is welded to the bottom end of the fixing seat; support beams are fixedly connected to both sides of the support plate, and a reinforcing base plate is fixedly installed at the bottom end of the support beams; two reinforcing base plates are fixedly connected to the support base plate; two support beams are symmetrically arranged about the support plate; and two reinforcing base plates are symmetrically arranged about the support base plate.

[0009] In use, the two reinforced base plates support the two support beams respectively, and the two support beams provide reinforcement support to the support plates. The fixed seat supports the base, and the base provides support to multiple support blocks.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model adopts a dual-positioning mechanism. A support plate provides support to the support platform, which in turn supports the robotic arm. The support plate supports the reinforcing support, which in turn supports the reinforcing frame. The workpiece is inserted into the positioning hole inside the positioning disc. An electric cylinder pushes the pressure plate, and the positioning motor drives the positioning shaft to rotate. An auxiliary motor also drives the positioning shaft to assist in rotation. The positioning disc drives the larger workpiece inside it under high load and stable operation, resulting in better high-load driving performance. Furthermore, by mounting welding equipment such as robots onto the positioner, the robots rotate together with the positioner. This avoids problems such as limited space, long welding times, and wire feeding tube tangling.

[0012] 2. This utility model adopts a reinforcement mechanism, which supports two reinforcement base plates through a support base plate. The two reinforcement base plates support two support beams respectively. The support base plates also support the fixed seat, and the fixed seat supports the base. This can provide reinforcement support force to the bottom of the support plate and greatly improve the high stability of the support plate during use. Attached Figure Description
