Description

Technical Field

[0001] The utility model relates to the technical field of positioners, in particular to a rotary and tilting hydraulic positioner. Background Art

[0002] The rotary and tilting hydraulic positioner is a device used in automated processing, mainly used in machine tool processing, automobile manufacturing, aerospace and other fields. It can realize functions such as rotation, tilting and displacement of workpieces. The equipment is mainly composed of a frame, a rotating mechanism, a tilting mechanism, a hydraulic system and a control system. The hydraulic system provides power to drive the rotation and tilting mechanisms to realize the displacement operation of the workpiece.

[0003] In many industrial production fields, especially in the heavy machinery manufacturing industry, large workpieces often need to be assembled and processed. Traditional manual operations are not only inefficient, but also prone to damage to workpieces and personal injury. Existing automatic positioners often have problems with poor stability and complex operation. Utility Model Content

[0004] In order to solve the problems in the related art, the utility model provides a rotary tilting hydraulic positioner, which solves the problems of poor stability and complicated operation.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] The utility model provides a rotary tilting hydraulic positioner including a base, wherein the middle portion of the base is hollow, and two tilted hydraulic cylinders are provided in the base, the two hydraulic cylinders are arranged in parallel and side by side, and a connecting valve is provided between the two hydraulic cylinders, and both ends of the base away from the hydraulic cylinder are fixed with protrusions, and a flip arm is provided between the protrusions, the flip arm is hinged to the protrusion, the flip arm and the protrusion are rotatably matched, and the flip arm is connected to the piston rod of the hydraulic cylinder; a rotary drive structure for clamping a workpiece is provided on the side of the flip arm away from the hydraulic cylinder.

[0007] In the above scheme, two parallel hydraulic cylinders are arranged, and a connecting valve is provided between the two hydraulic cylinders to ensure the pressure balance of the two hydraulic cylinders and realize movement synchronization. When the hydraulic cylinder drives the positioner to flip, the flipping process is stable and controllable, thereby solving the problem of poor stability. The hydraulic cylinder drives the flip arm to rotate, driving the rotary drive structure to rotate, so that the workpiece reaches a suitable welding or assembly position, thereby solving the problem of complex operation.

[0008] The rotary drive structure includes a slewing bearing and a disc body. The slewing bearing is located between the flip arm and the disc body. Three slide rails extending from the periphery of the disc body to the center are evenly arranged on one end of the disc body away from the slewing bearing. A gripper is slidably connected to the slide rails.

[0009] In the above solution, by setting the rotary drive structure, the sliding gripper is adjusted to the appropriate position according to the size of the workpiece, so that the workpiece can be accurately clamped.

[0010] The end of the piston rod is fixedly connected with a circular ring, and a positioning column is provided at the corresponding position of the flip arm. The circular ring is sleeved on the positioning column, so that the flip arm is connected to the hydraulic cylinder.

[0011] In the above solution, the ring and the positioning column are provided, and the ring is sleeved on the positioning column to connect the flip arm with the hydraulic cylinder, so that the piston rod of the hydraulic cylinder is extended and retracted, thereby driving the flip arm to rotate.

[0012] A horizontally arranged fixing plate is provided on one side of the base close to the flip arm, pillars are provided on both sides of the fixing plate, the distance between the two pillars is slightly larger than the diameter of the disc body, safety belts are provided between the pillars, and two groups of pillars are provided.

[0013] In the above scheme, the provision of a safety belt effectively prevents the rotating drive structure from failing to clamp the workpiece, causing the workpiece to fall and be damaged. In addition, the provision of two sets of pillars and safety belts improves the safety performance of the device.

[0014] Anchor bolts are arranged around the base, the fixing plate and the pillars, so that the base, the fixing plate and the pillars are fixedly connected to the ground.

[0015] In the above solution, anchor bolts are provided to fix the positioner to prevent displacement during use and to prevent dangerous accidents from occurring.

[0016] The base, fixing plate, support and flip arm are all welded and formed by Q355 steel.

[0017] The above solution adopts welding technology to ensure the strength and durability of the overall structure of the positioner.

[0018] The above solution has the following advantages:

[0019] When the hydraulic cylinder is driven by the hydraulic cylinder to drive the lifting of the lifting gear, the hydraulic cylinder is driven by the hydraulic cylinder to drive the lifting gear to move upwards, so that the lifting gear can be adjusted according to the needs of the lifting of the lifting gear.

[0020] 2. The rotary drive structure consists of a slewing bearing and a disc. A slide rail is provided on the end of the disc away from the slewing bearing, and a gripper is slidably connected to the slide rail. According to the size of the workpiece, the sliding gripper can be adjusted to the appropriate position to accurately clamp the workpiece. A ring is fixedly connected to the end of the piston rod. A positioning column is set at the corresponding position of the flip arm. The ring is connected to the positioning column, connecting the flip arm to the hydraulic cylinder. The piston rod of the hydraulic cylinder is extended and retracted, thereby driving the flip arm to rotate. A horizontally arranged fixed plate is provided on the side of the base near the flip arm. Supports are set on both sides of the fixed plate. A safety belt is installed between the supports to effectively prevent the rotary drive structure from failing to clamp the workpiece firmly, resulting in the workpiece falling and being damaged. There are two sets of supports, which improve the safety performance of the device. Anchor bolts are set around the base, fixed plate, and supports to ensure that the base, fixed plate, and supports are fixed to the ground, used to fix the positioner and prevent shifting during use and causing dangerous accidents. The base, fixed plate, supports, and flip arm are all welded and formed from Q355 steel, ensuring the strength and durability of the overall structure of the positioner.
