Description

Technical Field

[0001] The present invention relates to welding equipment, and more particularly to a small-sized auxiliary platform type welding workstation. Background Art

[0002] In industrial production, welding technology plays a pivotal role and is widely used in the fields of automotive parts, shipbuilding, engineering machinery, aerospace, metal processing, etc. With the development of advanced manufacturing technology, the automation and intelligence of welding product production has become an inevitable trend, and the use of robot welding has become one of the important signs of welding technology automation.

[0003] A welding workstation is an automated welding equipment, which is mainly composed of a protective body, a collaborative robot, a welding gun, a welding power source, a wire feeder, a wire feeder, a control cabinet, a gun cleaning station and a fixture. Each working part is integrated in the protective body. It stands out in the industry due to its strong mobility, high precision, high safety and more intelligent advantages. The protective body of the welding workstation can prevent damage to the eyes caused by the welding arc, and can also prevent most welding pollutants (such as smoke and other harmful gases) from spilling out. Therefore, the protective body is an important part of the welding workstation.

[0004] However, the protective function of the protective body is contradictory to the convenience of operation such as clamping and human-machine collaboration of the welding workstation. When the assisted welding workstation is in use, whether it is clamping different parts or dragging and teaching the welding robot, the operator needs to operate next to the clamping table of the welding workstation. Most of the existing protective body designs adopt a frame structure. Although the protective body of some welding workstations can be operated by opening doors on multiple sides, there are basically structures such as columns in the operating space, which limits the flexibility of operation. At present, the protective bodies of welding workstations are mostly rolling doors and sliding doors, which can only be opened on one side. There are many inconveniences for welding operations of some complex and heavy parts. For example, the protective body is not conducive to the hoisting operation of heavier parts, and the single-sided door opening is not conducive to the clamping or taking of parts and dragging and teaching operations. Although there are also protective bodies that can open doors on multiple sides, most of their door openings are separated by columns or partitions. This design cannot achieve the integrity of the operating space and is not conducive to operational flexibility. In addition, electric rolling doors open or close slowly, affecting production efficiency, such as the "a fixed robot welding processing center" disclosed in Chinese Patent No. ZL201520149647.0; full-open sliding doors tend to occupy lateral space after opening, such as the "a fully digitally controlled multifunctional integrated welding device" disclosed in Chinese Patent No. ZL202211193650.3.

[0005] In addition, the existing welding workstations have other deficiencies, such as: 1) Existing welding workstations use positioners (multi-axis clamping mechanisms) to cooperate with collaborative robots for welding operations, but the positions of the positioners and collaborative robots are relatively fixed. For some parts with complex structures, the collaborative robots need to move significantly to meet the welding requirements, which affects the welding efficiency on the one hand and is not conducive to the flexible clamping of parts in the welding workstation on the other hand. In response to this problem, Chinese patent number ZL202120717313.4 discloses "a new type of welding robot workstation", which sets slideways on the welding robot base and the robot support respectively, expanding the range of motion of the welding robot, but the welding robot can only be adjusted back and forth and up and down relative to the positioner, which is not suitable for parts with large horizontal welding spans.

[0006] 2) The welding workstation will inevitably produce some debris and impurities during the welding process. These debris and impurities fall and adhere to the work surface, which is difficult to clean, and the debris and impurities are easy to affect the subsequent clamping accuracy of the parts. Summary of the invention

[0007] 1. Technical problem to be solved by the invention

[0008] The object of the present invention is to overcome the above-mentioned shortcomings of the existing welding workstations and provide a small auxiliary platform welding workstation. The technical solution of the present invention is adopted. The front side of the top of the frame of the welding workstation is a cantilever structure, which is matched with the two-stage pneumatic lifting door on the front side of the frame, the half-open side sliding doors on both sides of the frame and the sliding top cover on the top of the frame. When the two-stage pneumatic lifting door, the side sliding door and the sliding top cover are all opened, the upper operating space of the clamping table is in an open state on all sides, and the operating space between the clamping table and the top of the frame is undivided, which greatly improves the convenience of hoisting, clamping and dragging teaching of welding parts, and is convenient for maintenance and cleaning of the welding workstation. At the same time, during welding work, the two-stage pneumatic lifting door, the side sliding door and the sliding top cover can be used to protect the welding area, which solves the contradiction between the convenience of clamping, human-machine collaboration and other operations of the existing welding workstation and the protection of the workstation; and the opening and closing action of the pneumatic lifting door is faster, and the side sliding door and the sliding top cover can be manually pushed and pulled to open and close, which has the advantages of simple and compact structure, quick and convenient operation, etc.

The frame 1 can adopt a frame structure, and an adjustable support foot is provided at the bottom thereof; in order to facilitate the movement of the welding workstation, a forklift hole is reserved at the bottom of the frame 1. A clamping table 1-2 and a mounting table 1-3 are horizontally arranged in the frame 1. According to the layout requirements, the mounting table 1-3 can be slightly higher than the clamping table 1-2. The collaborative robot 7, the wire feeder 11 and the gun cleaning station 12 are fixedly installed on the mounting table 1-3 respectively, wherein the collaborative robot 7 can be arranged in the middle of the mounting table 1-3, and the wire feeder 11 and the gun cleaning station 12 can be arranged on both sides of the mounting table 1-3; the welding gun 10 is installed on the collaborative robot 7, and the clamping displacement device 13 is installed on the clamping table 1-2; there is an equipment warehouse 1-4 below the mounting table 1-3, and the higher mounting table 1-3 can ensure the height space of the equipment warehouse 1-4, the welding power supply 15, the control cabinet 16 and the wire feeding reel 17 are respectively arranged in the equipment warehouse 1-4, and the wire feeding reel 17 is located below the wire feeder 11; the control cabinet 16 can adopt an integrated control cabinet. In order to facilitate the maintenance of the components in the control cabinet 16, the control cabinet 16 is preferably arranged on one side of the frame 1, so that the cabinet door of the control cabinet 16 can be opened from the side.

[0027] The front side of the top of the frame 1 is a cantilever structure, forming an operating space between the clamping table 1-2 and the top of the frame 1, and the lower part of the frame 1 is located on the front side of the clamping table 1-2 and is provided with a fixed baffle 1-1, and a pneumatically controlled first-level lifting door 4 is provided on the outer side of the fixed baffle 1-1, and a pneumatically controlled second-level lifting door 5 is provided on the outer side of the first-level lifting door 4.
