[0031] like Figure 1-Figure 3 As shown, an arc material adding device provided by an embodiment of the utility model includes: a mounting frame 1, a support plate 2, a welding gun 3, a driving assembly 4, a sensor component 5 and a controller.
[0032] Among them, the support plate 2 is slidably arranged on the mounting frame 1; the welding gun 3 is arranged on the support plate 2; the driving end of the driving component 4 is connected to the support plate 2, and the driving component 4 is used to drive the support plate 2 to drive the welding gun 3 to slide along the vertical direction on the mounting frame 1; the sensor component 5 is arranged on the support plate 2, and the sensor component 5 is used to detect the distance between the head of the welding gun 3 and the forming surface of the part; the controller is controlled and connected with the sensor component 5 and the driving component 4, and the controller is used to control the movement of the driving end of the driving component 4 according to the distance information detected by the sensor component 5.
[0033] When implementing it, Figure 1 As shown, when the welding gun 3 is working, when the sensing component 5 detects that the distance between the head of the welding gun 3 and the forming surface of the part is too close, the sensing component 5 feeds back the distance information to the controller, and the controller controls the driving end of the driving assembly 4 to drive the support plate 2 to drive the welding gun 3 together. At this time, the welding gun 3 slides on the mounting frame 1 along the vertical direction and gradually moves away from the forming surface of the part; when the sensing component 5 detects that the distance between the head of the welding gun 3 and the forming surface of the part is too far, the sensing component 5 feeds back the distance information to the controller, and the controller controls the driving end of the driving assembly 4 to drive the support plate 2 to drive the welding gun 3 together. At this time, the welding gun 3 slides on the mounting frame 1 along the vertical direction and gradually approaches the forming surface of the part. Compared with the traditional arc additive device, the present application feeds back the distance information to the controller through the sensing component 5, and then the controller controls the driving assembly 4 to drive the head of the welding gun 3 close to or away from the forming surface of the part, thereby realizing automatic adjustment of the distance and reducing the risk of collision between the welding gun 3 and the part during welding.
[0034] like Figure 1 and Figure 2 As shown, specifically, in this embodiment, the driving component 4 includes: a motor 401 and a screw rod 402, the motor 401 is connected to the controller control, and the motor 401 is fixedly set on the mounting frame 1; the screw rod 402 is set on the mounting frame 1, the screw rod 402 is connected to the driving end of the motor 401, and the end of the screw rod 402 away from the motor 401 is threadedly driven and connected to the support plate 2.
[0035] During operation, when the sensing component 5 detects that the distance between the head of the welding gun 3 and the forming surface of the part is relatively close, the controller controls the motor 401 to rotate forward according to the distance information fed back by the sensing component 5, and the motor 401 drives the screw rod 402 to rotate forward. At this time, the support plate 2 drives the welding gun 3 to slide on the mounting frame 1 along the axial direction of the screw rod 402, and the head of the welding gun 3 gradually moves away from the forming surface of the part; when the sensing component 5 detects that the distance between the head of the welding gun 3 and the forming surface of the part is relatively far, the controller controls the motor 401 to rotate reversely according to the distance information fed back by the sensing component 5, and the motor 401 drives the screw rod 402 to rotate reversely. At this time, the support plate 2 drives the welding gun 3 to slide on the mounting frame 1 along the axial direction of the screw rod 402, and the head of the welding gun 3 gradually approaches the forming surface of the part, completing automatic repair welding and making the surface of the part relatively flat. The controller controls the forward and reverse rotation of the motor 401 to adjust the distance between the head of the welding gun 3 and the forming surface of the part, which is convenient for operation and effectively reduces the risk of collision between the welding gun 3 and the part during welding.
[0036] Specifically, in this embodiment, the driving assembly 4 further includes a nut 403, which is disposed on the support plate 2, and the nut 403 is threadedly connected with the screw rod 402, and the nut 403 is used to drive the support plate 2 to perform linear reciprocating motion along the axial direction of the screw rod 402. Among them, the nut 403, the screw rod 402 and the motor 401 form a ball screw mechanism, and when the motor drives the screw rod 402 to rotate, the nut 403 is threadedly connected with the screw rod 402, so that the nut 403 drives the support plate 2 to perform linear reciprocating motion along the axial direction of the screw rod 402, thereby reducing the wear caused by the direct contact between the support plate 2 and the screw rod 402 for threaded driving.
[0037] like Figure 1 As shown, specifically, in this embodiment, the driving assembly 4 further includes a fixed block 404, which is arranged on the mounting frame 1, and one end of the screw rod 402 away from the motor 401 is rotatably connected to the fixed block 404 around its axis. When the motor 401 is started, the driving end of the motor 401 drives the screw rod 402 to start rotating, and the screw rod 402 is rotatably connected to the fixed block 404 around its axis, wherein the fixed block 404 may be provided with 1, 2, 4, 5, etc., and the number of the fixed blocks 404 is not specifically limited here, as long as the number and distribution position of the fixed blocks 404 meet the requirements of the rotation support screw rod 402, the fixed block 404 has a limiting effect on the screw rod 402, and ensures the structural stability of the screw rod 402 during the rotation of the screw rod 402 around its axis on the mounting frame 1.
[0038] like Figure 1 and Figure 2As shown, specifically, in this embodiment, a slide rail 6 is further provided on the mounting frame 1, and the support plate 2 is slidably connected to the mounting frame 1 through the slide rail 6. Among them, there can be one slide rail 6, or two, three, four or other multiple slide rails 6 arranged at intervals, and the number of the slide rails 6 is not specifically limited here, as long as the slide rail 6 can provide a sliding guide for the support plate 2, the structure of the slide rail 6 facilitates the support plate 2 to slide on the mounting frame 1, and reduces the wear on the surface of the mounting frame 1 caused by the support plate 2 sliding on the mounting frame 1.
[0039] like Figure 3 As shown, specifically, in this embodiment, the sensing component 5 is a laser distance sensor or an infrared distance sensor. The laser distance sensor is a device that uses a laser beam to measure distance and height, and has the characteristics of high precision, high speed, good stability, etc. When measuring height, the laser distance sensor mainly uses the quadrilateral measurement principle, that is, using three sides of known length to measure the length of the fourth side, and calculates the height value. By feeding back the detected height value to the controller, the controller controls the welding height of the driving welding gun 3, thereby reducing the risk of collision between the welding gun 3 and the parts during welding; the ultrasonic distance sensor has the advantages of reliable operation, easy installation, small emission angle, high sensitivity, etc. It is mainly composed of piezoelectric chips, which can both emit and receive ultrasonic waves. By detecting the distance between the surface of the part and the head of the welding gun 3, the setting height of the welding gun 3 is judged, and the accuracy of detection is improved.
[0040] It should be noted that after the equipment starts arcing, the wire feeding device is started, and the driving part in the wire feeding device controls the wire feeding wheel to send out the wire, and the wire is then connected to the head of the welding gun 3 through a hose and enters the molten pool; at this time, the sensor component 5 detects the distance between the surface of the part and the head of the welding gun 3, determines the setting height of the welding gun 3, and feeds back the distance information to the controller, and the controller controls the driving component 4 to complete the automatic adjustment of the printing height of the welding gun 3 to ensure that the welding gun 3 and the part do not collide during welding. When the distance detected by the sensor component 5 is small, it means that the printing thickness of the part at this place is large, and the arc additive device can drive the welding gun 3 to adjust the welding position together by moving the horizontal position of the mounting frame 1. When the sensor component 5 detects that the distance is large, it means that the printing thickness of the part at this place is small, and the arc additive device no longer moves the horizontal position of the mounting frame 1, so that the welding gun 3 continues to perform welding work at this welding position, avoiding defects such as holes caused by uneven printing, making the printed surface of the part smooth, and improving manufacturing efficiency.
[0041] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
