Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a center support welding workstation. Background Technology

[0002] The trailer center support is generally an important component of the trailer suspension system, typically consisting of components such as the main board and connecting plates. Its structural design must be able to reasonably transfer the weight of the trailer body to the axles and withstand forces in various directions during vehicle operation, such as vertical, horizontal, and lateral forces. The center support welding workstation emerged in this context, capable of selecting appropriate welding methods based on the center support material and welding requirements.

[0003] Existing mid-support welding workstations typically require personnel to clamp the parts before starting the welding robot for welding operations. However, existing welding workstations pose significant safety hazards and lack necessary safety protection devices. During the welding process, the robotic arm of the welding robot moves frequently, and if personnel are nearby, they are easily injured by collisions caused by the movement of the robotic arm. Therefore, this utility model provides a mid-support welding workstation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a central support welding workstation, which solves the problem that existing welding workstations have significant safety hazards, lack necessary safety protection devices, and that during the welding process, the robotic arm of the welding robot moves frequently, making it easy for people to be injured by collisions due to the movement of the robotic arm if they are nearby.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a center-support welding workstation, comprising a base, a welding robot mounted on the top of the base near the center, a tilting machine symmetrically mounted on the top of the base near the front, a clamping assembly on the tilting machine, and a protective assembly at the front of the base; the protective assembly comprises two bottom beams, symmetrically distributed on the left and right sides at the front of the base, the two bottom beams being parallel, a stop switch for controlling the welding robot mounted on the top surface of the bottom beams, two fixing plates mounted on the top surface of the bottom beams, the fixing plates being perpendicular to the bottom beams, the fixing plates extending outwards from the bottom beams, guide rods slidingly passing through the fixing plates, a bearing plate being fixedly connected between the bottoms of the two guide rods, a spring being installed between the opposite surfaces of the bearing plate and the fixing plates, the spring exerting an upward pulling force on the bearing plate, an L-shaped pressure plate being provided on the bearing plate, the vertical section of the L-shaped pressure plate being fixed to the bearing plate, and the horizontal section of the L-shaped pressure plate being positioned above the stop switch.

[0011] Beneficial effects

[0012] This utility model provides a mid-branch welding workstation. Compared with the prior art, it has the following advantages:

[0013] 1. When the welding operation is started, the welding robot of this mid-branch welding workstation begins to work. If a person accidentally enters the working area of ​​the welding robot and steps on the pedal, the pedal will sink under the force, causing the bearing plate to move downward against the tension of the spring. This will cause the horizontal section of the L-shaped pressure plate to press the stop switch, and the welding robot will stop working immediately. This avoids collision injuries to personnel caused by the movement of the welding robot's mechanical arm and effectively solves the problem of the lack of necessary safety protection devices in the existing mid-branch welding workstation.

[0014] 2. In this central support welding workstation, the operator can start or stop the operation of the entire welding workstation in an emergency by controlling the switch. When the welding operation is started, the welding robot starts working, and because the column is set in a position close to the device, it is convenient for personnel to operate.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides two technical solutions:

[0022] Figures 1-4 The first embodiment is shown: a center-support welding workstation, including a base 1, a welding robot 2 mounted on the top of the base 1 near the center, a tilting machine 3 symmetrically mounted on the top of the base 1 near the front, a clamping assembly 4 mounted on the tilting machine 3, and a protective assembly 5 mounted in front of the base 1; the protective assembly 5 includes two bottom beams 51, which are symmetrically distributed on the left and right sides in front of the base 1 and are arranged parallel to each other. A stop switch 52 for controlling the welding robot 2 is mounted on the top surface of the bottom beams 51, and a further mounting is also installed on the top surface of the bottom beams 51. There are two fixed plates 53, which are perpendicular to the bottom beam 51 and extend outward from the bottom beam 51. Guide rods 54 slide through the fixed plates 53, and a bearing plate 55 is fixedly connected between the bottoms of the two guide rods 54. A spring 56 is installed between the opposite surfaces of the bearing plate 55 and the fixed plates 53, and the spring 56 exerts an upward pulling force on the bearing plate 55. An L-shaped pressure plate 57 is provided on the bearing plate 55. The vertical section of the L-shaped pressure plate 57 is fixed to the bearing plate 55, and the horizontal section of the L-shaped pressure plate 57 is positioned above the stop switch 52. A pedal 58 is provided between the two bearing plates 55. The top surface of the pedal 58 has anti-slip texture, and the area of ​​the pedal 58 covers the movement range of the welding robot 2.

[0023] Specifically, under normal circumstances, the support plate 55 and its components are in the normal position under the tension of the spring 56. The horizontal section of the L-shaped pressure plate 57, which is in the normal position, is above the stop switch 52. When the welding operation is started, the welding robot 2 begins to work. If a person accidentally enters the working area of ​​the welding robot 2 and steps on the pedal 58, the pedal 58 will sink under the force, causing the support plate 55 to move downward against the tension of the spring 56. This will cause the horizontal section of the L-shaped pressure plate 57 to press the stop switch 52, at which point the welding robot 2 will immediately stop working. This avoids collision injuries to personnel caused by the movement of the robotic arm of the welding robot 2, effectively solving the problem of the lack of necessary safety protection devices in the existing mid-support welding workstation.

[0024] Furthermore, the anti-slip texture on the top surface of pedal 58 can prevent operators from slipping, further improving safety.

[0025] One of the bottom beams 51 has a column 6 installed on its top near the front side. A control switch 61 is installed on the top of the column 6. The control switch 61 integrates a start switch and an emergency stop switch.

[0026] Specifically, the operator can start or stop the entire welding workstation by controlling switch 61. When the welding operation is started, the welding robot 2 starts working, and because the column 6 is located close to the device, it is convenient for personnel to operate.

[0027] Figures 1-4 The second embodiment is shown, and its main difference from the first embodiment is that the clamping assembly 4 includes a tooling frame 41 mounted on the output end of the flipping machine 3. A limit plate 43 is mounted on the top of the tooling frame 41 near the rear side, and a plurality of positioning pins 44 matching the positioning holes of the center support are mounted on the front surface of the limit plate 43. A clamp 42 is mounted on the top of the tooling frame 41 near the front side, and the clamp 42 is used to clamp the center support. A support plate 45 is slidably provided on the top of the tooling frame 41, and the support plate 45 is used to provide auxiliary support for the center support.

[0028] Specifically, by placing the middle support component to be welded on the tooling frame 41 of the clamping assembly 4, the middle support is clamped by the clamp 42 to ensure that the middle support is fixed in position during the welding process. At the same time, the support plate 45 provides auxiliary support for the middle support to further ensure its stability. The positioning pin 44 on the limiting plate 43 matches the positioning hole of the middle support to assist in positioning the middle support, so that the middle support is accurately positioned during welding.

[0029] Furthermore, by setting up two flipping machines 3 and clamping components 4, welding efficiency can be significantly improved, the dwell time of the middle support at the workstation can be reduced, and the production progress can be accelerated.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle: When the welding operation is started, the welding robot 2 begins to work. If a person accidentally enters the working area of ​​the welding robot 2 and steps on the pedal 58, the pedal 58 will sink under the force, causing the bearing plate 55 to move downward against the tension of the spring 56. This will cause the horizontal section of the L-shaped pressure plate 57 to press the stop switch 52, at which point the welding robot 2 will stop working immediately. This avoids collision injuries to personnel caused by the movement of the robotic arm of the welding robot 2, and effectively solves the problem of the lack of necessary safety protection devices in the existing mid-support welding workstation.
