Description

Technical Field

[0001] This invention belongs to the field of automatic welding technology, and specifically relates to a wire feeding angle adjustment device for automatic welding equipment. Background Technology

[0002] The wire feeding angle adjustment device of automatic welding equipment is a crucial component, responsible for maintaining a stable and continuous feed of the welding wire to the welding area at a fixed angle, ensuring smooth welding operations. The accuracy and stability of the wire feeding angle directly impact welding efficiency and quality. During welding, there is often a need to adjust the wire feeding angle according to the welding location. By controlling the geometric spatial relationship of the molten droplet transition, precise adjustments to the droplet transition pattern and arc stability can be achieved, avoiding problems such as uneven molten pool shape, poor arc stability, and wire feeding obstruction caused by unreasonable angles, thus guaranteeing welding quality. Traditional wire feeding angle adjustment devices employ numerous connecting rods, hinged arms, and turntables to achieve multiple degrees of freedom adjustment. Furthermore, to ensure the structural strength and rotational stroke of these mechanical components, traditional devices are complex and bulky, resulting in limited welding positions and poor accessibility. Moreover, since each degree of freedom adjustment requires tightening one or more screws or nuts, operation is cumbersome, time-consuming, and labor-intensive, making it unsuitable for welding operations in special environments such as high temperatures and high radiation. To overcome the shortcomings of traditional devices, a new type of wire feeding angle adjustment device for automatic welding equipment needs to be developed.

[0003] The main challenge in developing the wire feeding angle adjustment device lies in addressing its bulky size and cumbersome angle adjustment. This invention utilizes a helical drive consisting of a screw and an internal thread to adjust the forward and backward displacement of the wire feeding tube, and a friction drive consisting of a rotating rod and a movable seat to adjust the vertical displacement of the wire feeding tube. The structural design and layout of the helical and friction drives allow the wire feeding angle adjustment device to be made thinner, resulting in a more compact and small overall structure, as well as flexible, reliable, and convenient adjustment. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic welding equipment wire feeding angle adjustment device, which solves the problems of existing wire feeding angle adjustment devices on welding equipment, such as complex structure, large size, poor adjustment flexibility, and inability to be applied in confined spaces.

[0014] In the aforementioned automatic welding equipment wire feeding angle adjustment device, the movable seat has a right-side channel that runs through the front and rear, which matches the left-side channel on the right side wall of the transverse slider, allowing the screw to pass through. By rotating the screw, the front and rear displacement adjustment mechanism is driven to adjust the front and rear position of the movable seat relative to the connecting seat.

[0018] To address the problems of existing wire feed angle adjustment devices on welding equipment, such as complex structure, large size, poor adjustment flexibility, and inability to be used in confined spaces, this invention provides an automatic wire feed angle adjustment device for welding equipment. For example... Figures 1-14 As shown, the device includes: a wire feeding tube 1 fixed to a wire feeding tube fixing seat 2 by a wire feeding tube clamp 28; the wire feeding tube fixing seat 2 is mounted on a movable seat 3 via a vertical displacement adjustment mechanism, allowing the wire feeding tube fixing seat 2 to move upwards or downwards relative to the movable seat 3 via the vertical displacement adjustment mechanism; the movable seat 3 is mounted on a connecting seat 4 via a front-to-back displacement adjustment mechanism, allowing the movable seat 3 to move forwards or backwards relative to the connecting seat 4 via the front-to-back displacement adjustment mechanism. A wire feeding tube clamp 28 is fixedly mounted on the wire feeding tube fixing seat 2, and the wire feeding tube 1 is fixed to the wire feeding tube fixing seat 2 by the wire feeding tube clamp 28.

[0019] During the process of wire feeding through the wire feeding tube 1, there will be a problem of wire shaking. If the wire shakes during welding, it will cause a poor molten pool shape and affect the weld quality, especially more seriously during long-term welding. The more stable the wire feeding is, the more stable the molten pool shape will be and the better the weld quality will be. In order to make the wire feeding process more stable and ensure the molten pool shape, a wire stabilizer 7 is provided on the wire feeding tube 1. The wire stabilizer 7 divides the wire feeding tube 1 into two sections, namely the upper wire feeding tube 11 and the lower wire feeding tube 12. The upper wire feeding tube 11 and the lower wire feeding tube 12 are connected by the wire stabilizer 7. The structure of the wire stabilizer 7 includes an upper connecting seat 71 and a lower connecting seat 72. The upper connecting seat 71 is fixed on the top surface of the lower connecting seat 72 through a connecting seat fastening component 8. The upper wire feeding tube 11 is fixed on the upper connecting seat 71, and the lower wire feeding tube 12 is fixed on the lower connecting seat 72. The connecting seat fastening component 8 includes a number of first fastening bolts 81. Each first fastening bolt 81 passes through the corresponding connecting through hole 711 on the upper connecting seat 71 and is tightened into the corresponding first threaded hole 721 on the lower connecting seat 72.

[0020] An upper channel 712 penetrating up and down is provided on the upper connecting seat 71. An installation cavity 722 and a lower channel 723 are opened downward on the top surface of the lower connecting seat 72. The installation cavity 722 includes a middle channel 7221, at least three peripheral channels 7222, and a lower installation channel 7223. The middle channel 7221, the peripheral channels 7222, and the lower installation channel 7223 are all vertically arranged channels. The peripheral channels 7222 are evenly spaced around the periphery of the middle channel 7221, in a "pin" shape. Each peripheral channel 7222 penetrates through the middle channel 7221. The lower installation channel 7223 is located outside any one of the peripheral channels 7222 and penetrates through this peripheral channel 7222. A number of rolling elements 82 are provided in each peripheral channel 7222. The rolling elements 82 are balls. The rolling elements 82 are arranged in a column from top to bottom to form a group of rolling elements 82. The opening size at the penetration between the peripheral channel 7222 and the middle channel 7221 ensures that each rolling element 82 will not脱出 through this opening outside the corresponding peripheral channel 7222. The number of the peripheral channels 7222 is preferably three, and the number of the rolling elements 82 in each column of the group of rolling elements 82 is preferably 4 - 5.

[0021] An upper mounting channel 713 is provided on the bottom surface of the upper connecting seat 71. The upper mounting channel 713 is located above the lower mounting channel 7223. The upper mounting channel 713 and the lower mounting channel 7223 together form a receiving cavity for accommodating the metal plate 83. The height of the receiving cavity is less than the height of the metal plate 83. After the welding wire passes through the upper wire feeding tube 11 and the upper connecting seat 71 in sequence, it passes through the middle channel 7221 and then enters the lower wire feeding tube 12. The welding wire located in the middle channel 7221 is located between each group of rolling elements 82, and the rolling surfaces of each rolling element 82 are arranged such that any rolling element 82 makes rolling contact with the welding wire. When the upper connecting seat 71 is fixed to the top surface of the lower connecting seat 72 by the connecting seat fastening assembly 8, the metal plate 83 located in the receiving cavity will be deformed due to its height being greater than the height of the receiving cavity. The metal plate 83 causes at least one rolling element 82 in the peripheral channel 7222 that penetrates the receiving cavity to move closer to the central channel 7221, so that the rolling element 82 can clamp the welding wire located between the groups of rolling elements 82, so that it can avoid shaking and be transported smoothly during the conveying process of the welding wire.

[0022] The upper wire feeding tube 11 is fixed to the upper connecting seat 71 in the following manner: a connecting joint 9 is fixedly provided at the bottom of the upper wire feeding tube 11, and the connecting joint 9 is inserted into the upper channel 712 and fixed in the upper channel 712 by a joint fastening assembly. The joint fastening assembly includes at least one second fastening bolt 91, each second fastening bolt 91 being screwed into a corresponding second threaded hole 714 on the side wall of the upper connecting seat 71 and abutting against the connecting joint 9. The areas on the connecting joint 9 pressed by each second fastening bolt 91 are all flat, so as to improve the reliability of the connection between the upper wire feeding tube 11 and the upper connecting seat 71.

[0023] The lower wire feeding tube 12 is fixed to the lower connecting seat 72 in the following manner: a connecting part 724 is provided in the lower section of the lower connecting seat 72. After the lower wire feeding tube 12 is sleeved on the connecting part 724, it is fixed to the connecting part 724 by the wire feeding tube 1 fastening assembly. The wire feeding tube 1 fastening assembly includes at least one third fastening bolt 92. Each third fastening bolt 92 is screwed into a corresponding third threaded hole 121 on the side wall of the lower wire feeding tube 12 and abuts against the connecting part 724 of the lower connecting seat 72. The connecting part 724 is a stepped shaft composed of a first shaft section 7241 and a second shaft section 7242. The diameter of the first shaft section 7241 is larger than the diameter of the second shaft section 7242. After the third fastening bolts 92 are tightened, they abut against the first shaft section 7241. The connection portion 724 of the lower connecting seat 72 is flat where each of the third fastening bolts 92 presses against it, so as to improve the reliability of the connection between the lower wire feeding tube 12 and the lower connecting seat 72.

[0024] The wire feeding tube fixing seat 2 is mounted on the movable seat 3 via a vertical displacement adjustment mechanism, and the wire feeding tube fixing seat 2 can move upward or downward relative to the movable seat 3 via the vertical displacement adjustment mechanism. The vertical displacement adjustment mechanism includes: a vertical groove 31 formed on the right side wall of the movable seat 3, and a vertical slider 21 provided on the left side wall of the wire feeding tube fixing seat 2. The vertical groove 31 and the vertical slider 21 are structurally matched, such that the vertical slider 21 is embedded in the vertical groove 31, and the slider 21 can only slide upward or downward in the vertical groove 31, and cannot laterally disengage from the vertical groove 31. The structure of the vertical groove 31 and the vertical slider 21 is as follows: the vertical groove 31 is a T-shaped groove structure, and the vertical slider 21 is a T-shaped slider structure that matches the shape of the vertical groove 31.

[0025] A through-hole 22 is provided on the wire feeding tube fixing seat 2. The rotating rod 5 passes through the through-hole 22 and is positioned by the axial positioning member 51, so that the rotating rod 5 can only rotate within the through-hole 22 and cannot move axially. The right side wall of the movable seat 3 is in frictional contact with the rotating rod 5, forming a friction transmission. This causes the wire feeding tube fixing seat 2 to move upward or downward relative to the movable seat 3 during the rotation of the rotating rod 5 through the friction between the right side wall of the movable seat 3 and the rotating rod 5. To improve the friction between the right side wall of the movable seat 3 and the rotating rod 5 and ensure that the friction transmission between the two is more stable and reliable, this solution performs knurling treatment on the right side wall of the movable seat 3 and the surface of the rotating rod 5 in rolling contact with the right side wall of the movable seat 3. A rotating rod knob 52 is fixedly provided at one end of the rotating rod 5 that extends out of the wire feeding tube fixing seat 2. The rotating rod knob 52 is provided to allow the operator to better grip the rotating rod 5 for rotation.

[0026] The top of the wire feeding tube fixing seat 2 is also provided with an upper limiting member 23. When the wire feeding tube fixing seat 2 moves downward relative to the movable seat 3, the upper limiting member 23 abuts against the top of the movable seat 3 and cannot move further downward. The bottom of the wire feeding tube fixing seat 2 is provided with a lower limiting member 24. When the wire feeding tube fixing seat 2 moves upward relative to the movable seat 3, the lower limiting member 24 abuts against the bottom of the movable seat 3 and cannot move further upward. In addition to the above limiting members, a left-right through limiting groove 25 is provided on the right side wall of the wire feeding tube fixing seat 2. An upper limiting threaded hole 32 and a lower limiting threaded hole 33 are provided on the right side of the movable seat 3. The upper limiting bolt 26 passes through the limiting groove 24 and is screwed into the upper limiting threaded hole 32. The lower limiting bolt 27 passes through the limiting groove 25 and is screwed into the lower limiting threaded hole 33. When the wire feeding tube fixing seat 2 moves downward relative to the movable seat 3 until the upper limiting bolt 26 abuts against the top of the limiting groove 25, it can no longer move downward. When the wire feeding tube fixing seat 2 moves upward relative to the movable seat 3 until the lower limiting bolt 27 abuts against the bottom of the limiting groove 25, it can no longer move upward. Furthermore, when the upper limiting bolt 26 and the lower limiting bolt 27 are tightened, the positions of the wire feeding tube fixing seat 2 and the movable seat 3 are locked. Either of the above two limiting structures can be used, or a combination of the two limiting structures can be employed. When the two limiting structures are combined, when the wire feeding tube fixing seat 2 moves downward relative to the movable seat 3 until the upper limiting member 23 abuts against the top of the movable seat 3, the upper limiting bolt 26 simultaneously abuts against the top of the limiting groove 25, providing double protection and ensuring that the wire feeding tube fixing seat 2 cannot move downward further. Conversely, when the wire feeding tube fixing seat 2 moves upward relative to the movable seat 3 until the lower limiting member 24 abuts against the bottom of the movable seat 3, the lower limiting bolt 27 simultaneously abuts against the bottom of the limiting groove 25, providing double protection and ensuring that the wire feeding tube fixing seat 2 cannot continue to move upward.

[0027] The movable seat 3 is mounted on the connecting seat 4 via a front-to-back displacement adjustment mechanism, and the movable seat 3 can move forward or backward relative to the connecting seat 4 through the front-to-back displacement adjustment mechanism. The front-to-back displacement adjustment mechanism includes: a transverse slider 41 disposed on the right side wall of the connecting seat 4, and a transverse groove 34 on the left side wall of the movable seat 3 that matches the transverse slider 41. The transverse groove 34 has a dovetail groove structure, and the transverse slider 41 has a dovetail-shaped slider structure that matches the shape of the transverse groove 34. Through the structure of the transverse groove 34 and the transverse slider 41, the transverse slider 41 is embedded in the transverse groove 34, and the transverse slider 41 can only slide forward or backward in the transverse groove 34 and cannot laterally disengage from the transverse groove 34. The movable seat 3 also has a right-side channel 35 with a semi-circular hole and internal threads that runs through the front and rear. The right side of the rear end of the transverse slider 41 extends to the right to form a rear baffle 42. On the right side wall of the transverse slider 41, a left-side channel 43 with a semi-circular hole and a bearing mounting hole 44 are sequentially formed from back to front. The right half of the bearing mounting hole 44 is located on the rear baffle 42, and a bearing 45 is installed in the bearing mounting hole 44. The left-side channel 43 and the right-side channel 35 together form a complete channel structure for the screw 6 to pass through. The screw 6 is screwed into the internal thread of the right-side channel 35, and the end of the screw 6 is supported by the bearing 45. A screw knob 61 is fixedly provided at the end of the screw 6 that extends out of the transverse slider 41, so that the operator can better grip the screw 6 for rotation. A front baffle 46 is fixedly installed on the front end face of the transverse slider 41. The space between the front baffle 46 and the rear baffle 42 is the movable area for the back-and-forth movement of the movable seat 3. A top threaded hole 36 is provided on the top surface of the movable seat 3, penetrating the top of the transverse sliding groove 34. A locking bolt 37 is screwed into the top threaded hole 36. When the locking bolt 37 is tightened, the bottom of the locking bolt 37 abuts against the transverse slider 41, locking the position of the transverse slider 41. When the locking bolt 37 is loosened outward, so that the bottom of the locking bolt 37 does not contact the transverse slider 41, the screw 6 can be rotated to adjust the back-and-forth position of the movable seat 3 relative to the connecting seat 4.

[0028] The screw 6 and the internal thread of the right channel 35 form a helical transmission to adjust the front and rear displacement of the wire feeding tube 1, and the rotating rod 5 and the right side wall of the movable seat 3 form a friction transmission to adjust the up and down displacement of the wire feeding tube 1.
