Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and in particular to an adaptively adjustable contact welding device. Background Technology

[0002] There are many types of welding machines, including single-point single-function, single-point dual-function, single-point multi-function, as well as two-point, three-point, four-point, and even six-point welding machines and corner welding machines. Different types of welding machines have different welding functions and working efficiencies. Typically, when using a silver contact welding machine, the operator needs to place the machine on an object at a fixed height for welding. However, this height is not suitable for all operators, making it uncomfortable to use. Therefore, patent "CN219520977U" proposes a high-efficiency silver contact welding device. This solution, through the action of a screw and a movable rod, allows for adjustment of the welding machine's height, thereby improving welding efficiency and providing the advantage of adjustable welding machine height. However, while this device satisfies the height adjustment method, it also has the drawback of having only one adjustment method. As the number of welding times increases, the electrode head will gradually wear down, causing changes in its contact resistance with the contact point, which in turn affects the transfer of welding current and heat. Traditional welding devices often cannot compensate for these changes in time, resulting in a gradual decline in welding quality and difficulty in ensuring product consistency. Therefore, this application proposes an adaptive adjustment contact welding device with timely adjustment and compensation functions for the welding electrode head. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing an adaptive adjustment contact welding device with timely adjustment and compensation functions for the welding electrode head.

[0004] The technical solution of this utility model is: an adaptive adjustment contact welding device, including a frame, a welding operation table for holding and placing chips, and a welding machine body for welding chips. The welding machine body includes connecting wires and electrode posts, and a connecting guide plate connecting the two is provided between the connecting wires and the electrode posts.

[0005] An adjustment mechanism is also provided between the welding machine body and the electrode post. The adjustment mechanism includes a connecting rod and a cylinder two installed between the connecting guide plate and the electrode post.

[0006] The adjustment mechanism also includes a rack and pinion for driving the two sets of connecting guide plates to move relative to each other.

[0007] Optionally, the adjustment mechanism further includes a drive motor embedded in the bottom of the welding machine body, and the gear is fixedly sleeved with the outer ring of the output end of the drive motor.

[0008] Optionally, the rack plates are arranged opposite to each other on the front and back of the gears, and the bottom ends of the two sets of gears are fixedly connected to telescopic rods, the bottom ends of which are fixedly connected to the top of the connecting guide plate.

[0009] Optionally, the adjustment mechanism further includes cylinders located on both sides of the gear, with lifting plates fixedly connected to the bottom of the output ends of the two sets of cylinders.

[0010] Optionally, a guide opening is provided in the lifting plate along its length direction, and the second cylinder and the connecting rod are slidably arranged in the guide opening.

[0011] Optionally, one end of the second cylinder is fixedly connected to the bottom of the connecting guide plate, and the output end of the second cylinder is rotatably mounted to the electrode post via a hinge seat.

[0012] Optionally, the bottom of the connecting rod is rotatably mounted between the electrode post and the ball joint.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This utility model achieves the adjustment of the practical height of the electrode post through the setting of a cylinder and a lifting plate, so as to realize the function of welding new products with different thicknesses or heights.

[0015] Furthermore, by setting up gears and racks, the two sets of connecting guide plates slide along the guide opening, thereby realizing the distance compensation adjustment of the electrode post;

[0016] This utility model also achieves compensation and adjustment of the welding angle at the bottom of the electrode post by setting up a connecting rod and cylinder two;

[0032] Example

[0033] like Figure 1As shown, this utility model proposes an adaptive adjustment contact welding device, including a frame 1, a welding operation table 2 for holding and placing chips, and a welding machine body 3 for chip welding. In this embodiment, a multi-sensor module group is also set to monitor the welding quality, welding distance, and welding angle, and upload the data to the control terminal of the entire welding device. The control terminal then controls the operation of all component drive devices in the welding device. The specific connection method and control program are not described in detail here. Figure 2 and Figure 3 As shown, the welding machine body 3 includes a connecting wire 31 and an electrode post 33, and a connecting guide plate 32 connecting the connecting wire 31 and the electrode post 33 is provided between the two.

[0034] like Figure 4 As shown, an adjustment mechanism 4 is also provided between the welding machine body 3 and the electrode post 33. The adjustment mechanism 4 includes a connecting rod 47 and a cylinder 48 installed between the connecting guide plate 32 and the electrode post 33. One end of the cylinder 48 is fixedly connected to the bottom of the connecting guide plate 32, and the output end of the cylinder 48 is rotatably installed between the electrode post 33 and the connecting rod 47 through a hinge seat. The bottom of the connecting rod 47 is rotatably installed between the connecting rod 47 and the electrode post 33 through a ball joint. Combined with the push of the output end of the cylinder 48, the electrode post 33 is rotated at an angle by the connecting rod 47 connected to the top, thereby realizing the compensation adjustment of the welding angle of the electrode post 33.

[0035] like Figure 3 and Figure 4 As shown, the adjustment mechanism 4 also includes a rack plate 45 and a gear 44 for driving the relative movement of the two sets of connecting guide plates 32, as shown in the figure. Figure 3 In terms of configuration, the rack plate 45 is positioned opposite to the front and back of the gear 44, and the bottom ends of the two sets of gears 44 are fixedly connected to the telescopic rod 46. The bottom end of the telescopic rod 46 is fixedly connected to the top of the connecting guide plate 32. The telescopic rod 46 enables the two sets of connecting guide plates 32 to move by meshing with the rack plate 45. The top of the rack plate 45 is also connected to a guide support block for support and is slidably disposed along the bottom shell of the welding machine body 3. The adjustment mechanism 4 also includes a drive motor 43 embedded in the bottom of the welding machine body 3, and the gear 44 is fixedly sleeved with the outer ring of the output end of the drive motor 43.

[0036] like Figure 3 and Figure 4 As shown, the adjustment mechanism 4 also includes cylinder 41 located on both sides of the gear 44. The bottom of the output end of the two sets of cylinder 41 is fixedly connected to the lifting plate 42. The lifting plate 42 has a guide port 420 along its length direction. Cylinder 48 and connecting rod 47 are slidably arranged in the guide port 420.

[0037] In this embodiment, the chip to be welded is placed on the welding operation table 2, and contact welding is achieved through the setting of the welding machine body 3. When the welding height needs to be adjusted, the lifting plate 42 is pushed by the start of the cylinder 41, thereby moving the electrode post 33 downward to adapt to the height compensation adjustment. During the height adjustment process, the setting of the telescopic rod 46 ensures the continuous connection of the connecting guide plate 32.

[0038] The rack plate 45 is driven to rotate by the gear 44, which in turn moves the gear 44. The rotation of the gear 44 causes the rack plate 45 to move, which in turn moves the two connecting guide plates 32 stably along the guide opening 420, thereby achieving compensation adjustment of the distance between the connecting guide plates 32.

[0039] By pushing or pulling the output end of cylinder 48, the top side of electrode post 33 is pressed down or lifted, so that the bottom contact of electrode post 33 is adjusted by the spherical universal joint set at the bottom of connecting rod 47.

[0040] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
