Description

Technical Field

[0001] The utility model belongs to the technical field related to the production of vibratory screens, and particularly relates to a new type of laser robot welding workstation for the discharge port. Background Technique

[0002] As a relatively standard general part of the vibratory screen equipment, each equipment has at least 2 - 3 discharge ports. Therefore, a large amount of repetitive work is generated in the welding of the discharge ports. The workload of grinding and polishing caused by unqualified welding quality of the welds is doubled. Therefore, the quality requirements for welding operations are very high. It is required that the weld reinforcement and penetration meet the standards while avoiding defects such as burn-through, undercut, and false welding. Generally, manual tungsten inert gas arc welding is mainly used at present. During the welding process, it is difficult to control the welding quality, and the labor intensity of the subsequent process workers for grinding and polishing the welds is large. Therefore, welding by a welding robot can greatly reduce the labor intensity of welding and improve the welding efficiency of the discharge port. However, it still has the following disadvantages in actual use:

[0003] During the welding process of the robot, all components need to be clamped by fixture jigs. During the clamping process, multiple clamping steps are required for production, which will result in more welding steps and affect the production efficiency. When working, the alignment of each component requires processing by high-precision processing equipment, the equipment cost is high, and the production efficiency is not high enough;

[0004] During the welding process of the robot, the discharge port needs to be clamped by a fixture. During the operation process, the fixture needs to precisely clamp the tooling. During the clamping process, more meticulousness is required, and the operation is not convenient enough. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a new type of laser robot welding workstation for the discharge port. By setting a support frame, a fixed bracket, a pressing electric push rod, and a welding robot, the problems that the operation steps are more when the robot welds the discharge port, the production efficiency of precise clamping is not high enough, and the operation is not convenient enough when clamping because it requires the operator to be meticulous are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a novel laser robot welding workstation for a discharge port, which comprises a support frame, a fixed bracket, a pressing electric push rod and a welding robot. A bottom bracket is fixed at the bottom of the support frame. On one side of the center line parallel to the short side at the top of the support frame, a hydraulic lift 1 is fixed. The piston rod of the hydraulic lift 1 penetrates and is movably connected to the top of the support frame. The bottom end of the piston rod of the hydraulic lift 1 is fixed with a lifting plate. A base is arranged below the lifting plate. An outlet main body is movably connected between the base and the lifting plate. An outlet clamp is spot-welded at the front end of the outlet main body. On one side of the bottom bracket, two symmetrically arranged fixed brackets are provided. A servo motor is fixed at the edge of the top of the fixed bracket close to the bottom bracket. A bottom plate is fixed at the bottom of the fixed bracket. A support column is fixed at the edge of the short side of the bottom plate away from the fixed bracket. A pressing electric push rod is fixed at the top of the support column. A welding robot is arranged on the side of the two fixed brackets away from the support frame. During operation, the hydraulic lift 1 and the hydraulic lift 2 are supported on the support frame. The hydraulic lift 1 and the hydraulic lift 2 cooperate to provide a clamping effect for spot-welding the outlet main body and its upper components and the outlet clamp during welding. The servo motor is supported on the fixed bracket. The servo motor drives the electric three-jaw chuck to rotate. The pressing electric push rod drives the rotating pressing block to press on the outlet main body, so that the outlet main body is well restricted. The welding operation is carried out by the welding robot.

[0008] Further, a hydraulic lift 2 is fixed at a position symmetrical to the hydraulic lift 1 at the top of the support frame. The piston rod of the hydraulic lift 2 penetrates and is movably connected inside the support frame. The bottom end of the piston rod of the hydraulic lift 2 is fixed with a pressure plate. The support frame drives the pressure plate to lift through the hydraulic lift 2.

[0009] Further, an outlet main body and an outlet clamp spot-welded on the outlet main body are arranged between the pressure plate and the bottom bracket. The outlet clamp is spot-welded on the circumferential side of the outlet main body between the pressure plate and the bottom bracket, so that the outlet main body is well restricted during operation.

[0010] Further, an electric three-jaw chuck is fixed at the output end of the servo motor. A transverse electric push rod is fixed on the side of the fixed bracket close to the support column. The servo motor clamps the outlet main body from the inside through the three-jaw chuck.

[0011] Further, the telescopic end of the transverse electric push rod is fixed with a top electric push rod. The telescopic end of the top electric push rod is fixed with a lifting bracket. A support plate is fixed on the side of the lifting bracket close to the support column. The transverse electric push rod and the top electric push rod cooperate to support the lifting bracket well.

[0013] The utility model has the following beneficial effects:

[0014] By arranging the support frame, the utility model solves the problems that the operation steps are more when the robot welds the discharge port, and the precision clamping production efficiency is not high enough. The main body of the discharge port is placed on the base, and then, in the pneumatic hydraulic lift 1, the lifting plate is driven to descend to press the base. After completion, the main body of the discharge port is restricted. Then, the discharge port clamp can be placed on the main body of the discharge port, and then spot welding operation is carried out, so that the discharge port clamp is spot welded to the main body of the discharge port. Then, by arranging the main body of the discharge port on the bottom support frame with the end with the discharge port clamp facing down, and then the pressing disc is driven to descend to the main body of the discharge port by the hydraulic lift 2. After placing other components of the main body of the discharge port at appropriate positions on the surface of the main body of the discharge port, spot welding is carried out, so that all structures on the main body of the discharge port are spot welded together. During work, each component of the discharge port is already spot welded and fastened during the welding process of the robot, the operation steps of clamping the discharge port are fewer, and the precision clamping production efficiency is higher.

[0015] By arranging the fixed bracket, the pressing electric push rod and the welding robot, the utility model solves the problem that the operation is not convenient enough and requires careful operation by the operator during the clamping process in the welding process of the robot. After spot welding the components on the main body of the discharge port to the main body of the discharge port and the discharge port clamp, the pressing electric push rod is started, so that the rotating pressing block moves away from the electric three-jaw chuck. Then, the transverse electric push rod is started. The transverse electric push rod drives the top electric push rod, and at the same time, the top electric push rod drives the lifting bracket to drive the support plate to rise to the outside of the electric three-jaw chuck, and the position where the main body of the discharge port is spot welded with the discharge port clamp is set to the outside of the electric three-jaw chuck. The structure with components spot welded thereon is arranged above the electric three-jaw chuck and is supported by the support plate. Then, the electric three-jaw chuck is started to clamp the main body of the discharge port. During the clamping process in the welding process of the robot, the operator does not need to operate carefully, and the operation is more convenient. Description of the Drawings
