Description

[0002] For connecting rod components formed by welding two bushings to the two ends of a rod (such as Figure 9 As shown in the figure, butt welding machines are typically used to weld components. A butt welding machine utilizes the resistance heating effect, passing a strong current through the ends of two workpieces, generating high temperatures. When the temperature reaches a certain level, the metal material softens or even melts. At this point, a certain amount of pressure is applied to tightly bond the ends of the two workpieces together, forming a strong weld joint.

[0003] During welding, the round rod and the bushings at both ends need to be clamped and fixed separately using a welding jig. However, the existing fixture structure for clamping the round rod is relatively complex. In order to achieve centering, a drive mechanism is set on both sides, which occupies a large space and requires high costs. In addition, the existing butt welding machine has a low degree of automation, and the mechanism linkage logic performance in the process of loading and unloading, and handling of materials and workpieces is poor, which affects the production efficiency of the product.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0037] Example 1

[0038] like Figure 4-Figure 5 As shown, a welding jig suitable for connecting rod components includes a support seat 22 with a groove on the top, a positioning support 25 for supporting the rod 81 is provided at the bottom of the groove, and clamping blocks 23 for clamping the rod 81 are provided on both sides of the positioning support 25; a guide rod 26 perpendicular to the rod 81 is movably provided on the support seat 22, one end of the guide rod 26 is installed with a connecting block 27, and the other end is installed with a telescopic component 24; the telescopic component 24 includes a base 241 connected to the guide rod 26 and a telescopic rod 242 that can be extended and retracted, the end of the telescopic rod 242 is connected to the clamping block 23 on one side, and the connecting block 27 is connected to the clamping block 23 on the other side through a push rod 28.

[0039] As mentioned above, the telescopic assembly 24 can adopt existing technologies such as oil cylinders, air cylinders and electric cylinders that output linear motion. If an air cylinder is used, the base 241 is relative to its cylinder body, and the telescopic rod 242 is equivalent to its piston rod. The telescopic assembly 24 here is different from the ordinary installation method. Its cylinder body is floating, and the piston rod is fixedly connected to the clamping block 23. When the output end of the telescopic assembly 24 (i.e., the telescopic rod 242) is extended, the base 241 is first away from the support seat 22 due to the resistance of the clamping block 23, and is brought into contact with the guide rod 26. The movable connecting block 27 approaches the support seat 22, and the connecting block 27 drives the push rod 28 to push the proximal clamping block 23 toward the middle position of the groove until the connecting block 27 is abutted against the support seat 22. The base 241 stops moving away from the support seat 22 due to the pulling restriction of the guide rod 26. At this time, the telescopic rod 242 continues to extend relative to the base 241, pushing the clamping block 23 on this side toward the middle position, and finally completing the clamping and fixation of the rod 81; similarly, the action of the telescopic assembly 24 is opposite when the rod 81 is released.

[0040] The welding jig occupies a small space, and a telescopic assembly 24 can drive the clamping blocks 23 on both sides of the positioning support 25 to move horizontally toward the middle position to clamp and fix the rod 81, which not only reduces costs but also facilitates use in narrow spaces.

[0041] The guide rod 26 is located below the push rod 28 and telescopic rod 242, which are then inserted into the upper portion of the support base 22. To facilitate clamping and fixation, the clamping block 23 has an arc-shaped groove on the side near the positioning support 25 that aligns with the contour of the rod 81. To facilitate support for the rod 81, a V-shaped groove is provided on the top of the positioning support 25. Multiple positioning supports 25 are provided, spaced apart to accommodate rods 81 of varying lengths.

[0042] Example 2

[0043] On the basis of the first embodiment, the present invention also proposes a butt welding machine suitable for connecting rod components, which welds the bushing 82 to both ends of the rod 81 through steps such as loading, transporting, and welding to form a workpiece, and performs size detection and lettering marking on the workpiece.

[0044] like Figure 1-Figure 2 As shown, a butt welding machine suitable for connecting rod components includes a frame 1 and a loading device. The frame 1 is provided with a welding positioning mechanism 2, a conveying mechanism 3 and a detection mechanism 7, and the loading device, the welding positioning mechanism 2 and the detection mechanism 7 are distributed in sequence along the Y-axis direction, that is, the loading device and the detection mechanism 7 are distributed on both sides of the welding positioning mechanism 2, and the conveying mechanism 3 is located above the welding positioning mechanism 2.

[0045] As mentioned above, the welding positioning mechanism 2 is used to fix the bushing 82 at both ends of the rod 81, the loading device is used to provide materials, including the rod 81 and the bushing 82, the detection mechanism 7 is used to perform size detection and engraving marking on the workpiece after welding, and the conveying mechanism 3 is used to convey the material from the loading station to the welding station, and to convey the welded workpiece from the welding station to the detection and engraving station, and to convey and collect the workpiece from the detection and engraving station.

[0046] After the material is transported to the designated position by the loading device, it is transferred by the transport mechanism 3 to the welding positioning mechanism 2 for welding. After the workpiece is formed, it is transported to the inspection mechanism 7 for size inspection and engraving, and then the material is unloaded and collected. The equipment has close coordination and strong linkage between the loading, welding, transporting and inspection stations, which can improve the production efficiency of the product.

[0047] like Figure 4 As shown, the welding positioning mechanism 2 includes a welding base 21 fixedly mounted on the frame 1, a welding jig is slidably mounted on the welding base 21 along the X-axis direction, and a rotating jig 29 for clamping the bushing 82 is slidably mounted on both ends of the welding jig.

[0048] During welding, the rod 81 is parallel to the X-axis direction. The welding jig proposed in this patent is used to clamp and fix the rod 81, and the rotating jig 29 is used to clamp and fix the bushing 82. The bushing 82 is perpendicular to the axis of the rod 81, and the rotating jig 29 can also drive the bushing 82 to rotate a certain angle around the axis of the rod 81 to meet the welding of products with different angle standards.

[0049] After the rod 81 and the bushing 82 are clamped and fixed in place, electricity is applied to conductive copper plates and other components to locally heat the rod 81 and the bushing 82. Then the welding jig and the two rotating jigs 29 are moved closer to each other along the X-axis direction until the bushing 82 abuts against the end of the rod 81, completing the welding.

[0050] Among them, the rotating jig 29 can adopt existing technology, such as an electrode welding jig proposed in Chinese patent application number 2023107675346 on June 27, 2023, to achieve the effect of welding two bushings 82 to both ends of the rod 81 in one clamping.

[0051] like Figure 1 、 Figure 3 As shown, the transport mechanism 3 includes a transport bracket 31 fixedly mounted on the frame 1, and a first base plate 32 and a second base plate 33 that can move along the Y-axis direction are provided on one side of the transport bracket 31.

[0052] A first slide 35 that can be raised and lowered along the Z-axis direction is slidably installed on one side of the first base plate 32. An intermediate clamp 351 for clamping the rod 81 is installed at the bottom of the first slide 35. Side clamps 352 for clamping the bushing 82 are provided on both sides of the intermediate clamp 351 along the X-axis direction.

[0053] A second slide plate 36 that can be lifted and lowered along the Z-axis is slidably mounted on one side of the second base plate 33 . A transfer clamp 361 and a blanking clamp 362 for clamping a workpiece are provided at the bottom of the second slide plate 36 , and the two are spaced apart along the Y-axis.

[0054] As mentioned above, the first slide 35 and the second slide 36 are both located above the welding positioning mechanism 2, and the transport bracket 31 adopts a gantry structure. The sliding of the first base plate 32 relative to the transport bracket 31 along the Y-axis direction and the sliding of the first slide 35 relative to the first base plate 32 along the Z-axis direction can both be achieved by using existing technologies, such as a linear guide rail assembly in conjunction with a linear drive module (cylinder, electric cylinder, oil cylinder, etc.). The movement of the second base plate 33 and the second slide 36 is the same.

[0055] The first base plate 32 and the second base plate 33 are slidably mounted on the same linear guide assembly. The two can move synchronously along the Y-axis direction or independently. When moving independently, they are driven by linear drive modules respectively, and when moving synchronously, they can be driven by one linear drive module.

[0056] When the first base plate 32 and the second base plate 33 are fixedly connected by the connecting rod 34 , the two can move synchronously along the Y-axis direction, and only one linear drive module is required to drive them.

[0057] Here, a structure in which the first base plate 32 and the second base plate 33 move synchronously is adopted. The middle clamp 351, the transfer clamp 361 and the blanking clamp 362 have the same structure and adopt the existing three-point contact clamp, which is more stable when clamping the rod 81 compared to two-point or four-point contact; the side clamp 352 also adopts the existing technology, adopts a two-point contact clamp, and clamps from the outer circumferential surface of the bushing 82.

[0058] Specifically, the first slide 35 and the second slide 36 rise and fall synchronously, the former drives the middle clamp 351 and the side clamp 352 to clamp the rod 81 and the bushing 82 from the loading station, and the latter drives the transfer clamp 361 and the unloading clamp 362 to rise and fall to clamp the workpiece from the welding station and the inspection station respectively; then the first base plate 32 and the second base plate 33 move synchronously along the Y-axis direction for a station distance, the rod 81 clamped by the middle clamp 351 is placed on the positioning support 25, the bushing 82 clamped by the side clamp 352 is placed on the rotating fixture 29 and fixed, the workpiece clamped by the transfer clamp 361 is placed on the inspection mechanism 7, and the workpiece clamped by the unloading clamp 362 is unloaded and collected; then the conveying mechanism 3 is reset, and the cycle is repeated.

[0059] like Figure 1 、 Figure 6 、 Figure 8 As shown, the feeding device includes a first feeding mechanism 4, a second feeding mechanism 5 and a dividing mechanism 6, wherein two second feeding mechanisms 5 are provided, respectively corresponding to the bushings 82 at both ends of the rod 81, the dividing mechanism 6 is arranged on the frame 1, and the two second feeding mechanisms 5 are relatively distributed on both sides of the dividing mechanism 6, and the first feeding mechanism 4 is located on one side of one of the second feeding mechanisms 5.

[0060] The first feeding mechanism 4 is used to provide a rod 81 to the dividing mechanism 6, and the second feeding mechanism 5 is used to provide a sleeve 82 to the dividing mechanism 6. The rod 81 and the sleeve 82 converge at the dividing mechanism 6, and then feed the materials to the middle clamp 351 and the side clamp 352 of the conveying mechanism 3 in portions. Here, a single portion of material includes a rod 81 and two sleeves 82 located at both ends of the rod 81.

[0061] As mentioned above, the material dividing mechanism 6 includes a material dividing bracket 61 fixedly mounted on the frame 1, and two material receiving blocks 62 are relatively arranged on the top of the material dividing bracket 61. The material receiving block 62 is provided with a material storage trough parallel to the Y-axis direction, and the output end of the second feeding mechanism 5 is connected to the rear end of the material storage trough, and the front end of the material receiving block 62 is provided with a positioning block 63 for blocking the bushing 82, and the rear end of the material receiving block 62 is provided with a push rod 64 for pushing the bushing 82 forward along the Y-axis direction.

[0062] The length direction of the material storage trough is parallel to the Y-axis, and the gap between the positioning block 63 and the end surface of the material storage trough can just accommodate a bushing 82; when the bushing 82 is transported to the material storage trough by the second loading mechanism 5, the push rod 64 at the rear end of the receiving block 62 moves forward a distance of the width of the bushing 82, and then retracts, and when the next bushing 82 falls into the material storage trough, it moves forward a distance of the width of the bushing 82; when the material storage trough is full, the push rod 64 can push the bushings 82 forward one body position, and finally fall one by one between the positioning block 63 and the receiving block 62, so that they can be grasped by the side clamps 352.

[0063] Among them, the push rod 64 is installed at the rear end of the material receiving block 62, one end of which can extend into the material storage trough, and the other end is connected to the output end of the linear drive module; and the second feeding mechanism 5 here adopts existing technology, such as a vibration plate.

[0064] Furthermore, the front end of the material distribution bracket 61 is provided with a material receiving plate 65 that can be raised and lowered along the Z-axis direction. The top of the material receiving plate 65 is provided with a material receiving groove parallel to the X-axis direction, and one end of the material receiving groove is closed, and the other end is connected to the output end of the first feeding mechanism 4.

[0065] The length direction of the material receiving trough is parallel to the X-axis, and the length of the material receiving trough is less than or equal to the length of the rod 81; in the initial state, the material receiving plate 65 is below the material receiving block 62. As the rear rod 81 pushes, the front end rod 81 enters the material receiving trough, and the end of the rod 81 rests on the inner side of the closed end of the material receiving trough. Then the material receiving plate 65 moves up along the Z-axis and sends the rod 81 to a position where the middle clamp 351 can grasp it, and it is grasped by it.

[0066] In order to facilitate the middle clamping jaw 351 to grasp the rod 81, a notch connected to the material receiving trough is opened on the top of the material receiving plate 65; and a linear drive module, such as a cylinder, is installed at the front end of the material distribution bracket 61 for driving the material receiving plate 65 to rise and fall.

[0067] In addition, the first loading mechanism 4 adopts existing technology, such as a stepped conveying mechanism, including a hopper 41, and a stepped boss is provided on the front wall inside the hopper 41. A plurality of top plates 42 that can be raised and lowered synchronously are also provided on one side of the boss. As the top plate 42 rises and falls back and forth, the rod 81 will be lifted step by step until it falls on the conveying rack 45. A conveying chain 46 is rotatably installed on the top of the conveying rack 45, and guards are provided on both sides of the conveying chain 46 to prevent the rod 81 from falling; as the conveying chain 46 rotates, the rod 81 can be conveyed in a straight line to the receiving trough.

[0068] Among them, in order to adapt to the transportation of rods 81 of different lengths, a support rod 44 parallel to the axis of the rod 81 is provided in the silo 41, and a baffle 43 is slidably sleeved on the support rod 44. According to the length of the rod 81, the position of the baffle 43 on the support rod 44 can be adjusted to ensure that the rods 81 can be lifted to the top one by one, and then enter between the two side walls of the conveying frame 45, and are driven forward by the conveying chain 46.

[0069] like Figure 1 、 Figure 7 As shown, the detection mechanism 7 includes a detection bracket 71 fixedly mounted on the frame 1. A support block 72 for supporting the workpiece is fixedly mounted on the top of the detection bracket 71 along the X-axis direction. A fixing plate 73 is mounted on one end of the support block 72, and a push plate 74 that can move along the X-axis direction is provided on the other end. A distance measuring component 75 is provided on one side of the push plate 74.

[0070] The support block 72 has multiple sections, which are spaced apart along the X-axis direction, and a positioning groove for positioning the workpiece is provided on the top of the support block 72; when the workpiece is placed on the support block 72 by the transfer clamp 361, the push plate 74 pushes the workpiece to move along the X-axis direction under the action of the linear drive module until its two ends contact the push plate 74 and the fixed plate 73 respectively, at which time the distance moved by the push plate 74 is measured by the distance measuring component 75.

[0071] The distance measuring component 75 can use a laser rangefinder. Since the moving distance of the push plate 74, the initial distance between the fixed plate 73 and the push plate 74, and the thickness of the push plate 74 are all known, the length of the workpiece can be calculated to determine whether it is qualified.

[0072] Furthermore, a pressing block 76 capable of flipping and fixing the workpiece in the longitudinal direction is installed on one side of the support block 72, and an engraving assembly 78 for engraving marks on the workpiece is provided on the other side.

[0073] A telescopic component 77 is installed on the detection bracket 71. The telescopic component 77 adopts existing technologies such as cylinders. The bottom of the pressure block 76 is rotatably connected to the detection bracket 71, and the back is connected to the output end of the telescopic component 77. In addition, the upper part of the front side of the pressure block 76 has a hook-like structure. When it is turned close to the workpiece under the drive of the telescopic component 77, the workpiece can be firmly fixed on the support block 72 through the hook-like structure; then the engraving component 78 is used to engrave marks on the rod of the workpiece, such as model size, production date and code; and the engraving component 78 preferably adopts existing laser engraving technology.

[0074] Working principle: the rod 81 and the bushing 82 are respectively transported to the dividing mechanism 6 by the first feeding mechanism 4 and the second feeding mechanism 5, and are provided to the conveying mechanism 3 one by one by the dividing mechanism 6; the conveying mechanism 3 grabs the rod 81 and the bushing 82 through the middle clamp 351 and the side clamp 352, and then conveys them to the welding station, that is, the welding positioning mechanism 2. After the material is welded, the workpiece is formed. The conveying mechanism 3 then transfers it from the welding station to the inspection station for inspection and engraving through the transfer clamp 361, and then unloads it from the inspection station to the outside for collection through the unloading clamp 362, and the above-mentioned transfer work can be carried out simultaneously.

[0075] To sum up, the utility model proposes a welding jig that can be used to fix and clamp the rod 81. Compared with the existing technology, it not only reduces the manufacturing cost, but also is more convenient to use in a narrow space. It also proposes a butt welding machine. The equipment has close coordination between the loading, welding, transportation and testing stations, strong linkage logic, and can improve the production efficiency of the product.
