Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to an intelligent automated production equipment for automotive muffler manufacturing. Background Technology

[0002] Automotive mufflers are parts used to reduce the noise generated by the engine of motor vehicles. The processing of automotive mufflers requires the use of spot welding machines. Spot welding machines are mechanical devices that employ the principle of double-sided, double-point overcurrent welding. During operation, two electrodes press against the workpiece, causing the two layers of metal to form a certain contact resistance under the pressure of the electrodes. When the welding current flows from one electrode to the other, an instantaneous heat fusion occurs at the two contact resistance points. However, existing spot welding machines for automotive mufflers generally have fixed welding points. When switching between different models of automotive mufflers, the spot welding machine cannot be adjusted according to the user's needs, and can only perform welding at fixed points, greatly increasing the welding difficulty of the device. This is especially true for multi-point spot welding machines, where the inability to adjust reduces the welding efficiency. Therefore, we propose an intelligent automated production equipment for automotive muffler manufacturing. Summary of the Invention

[0035] Example 1

[0036] Please see Figure 1-6 This invention provides a technical solution: an intelligent automated production equipment for manufacturing automotive mufflers, comprising a spot welding machine body 1, a welding head 11, a support plate 12 fixedly connected to the spot welding machine body 1, and further comprising...

[0037] Sliding plate 2, multiple sliding plates 2 are evenly and equidistantly arranged along the support plate 12;

[0038] The lifting assembly 3 connects the welding head 11 to the sliding plate 2. The lifting assembly 3 drives the welding head 11 to move down and contact the workpiece, thereby completing the normal welding operation.

[0039] The lifting assembly 3 includes an electric push rod 31 disposed between the welding head 11 and the sliding plate 2. The two ends of the electric push rod 31 are fixedly connected to the welding head 11 and the sliding plate 2, respectively. After the operator places the workpiece, he starts the electric push rod 31 to drive the welding head 11 to move down to contact the workpiece and complete the welding.

[0040] Adjustment component 4 is set on sliding plate 2. Adjustment component 4 drives sliding plate 2 to move and adjust along support plate 12. Specifically, adjustment component 4 includes mounting plate 32 fixedly connected to one side wall of spot welding machine body 1. Guide rod 33 is fixedly connected to mounting plate 32. Guide rod 33 slides through multiple sliding plates 2 and guides and limits the movement of sliding plate 2.

[0041] The mounting plate 32 has a slide groove 34, and one end of the electric push rod 31 passes through the slide groove 34 to avoid the movement of the electric push rod 31.

[0042] A mounting frame 35 is fixedly connected to the main body 1 of the spot welding machine. Multiple shafts 36 are rotatably connected to the mounting frame 35 through bearings. Each shaft 36 corresponds to a sliding plate 2. A linkage component 37 is provided between the shaft 36 and the sliding plate 2. Rotating the shaft 36 drives the sliding plate 2 to move by means of the linkage component 37.

[0043] The linkage component 37 includes a connecting block 38 fixedly connected to the sliding plate 2, a screw 39 fixedly connected to the shaft 36, a slider 41 threadedly connected to the screw 39, and a connecting rod 42 between the slider 41 and the connecting block 38. The connecting rod 42 has two rods symmetrically arranged relative to the connecting block 38, thereby improving the stability of the main body of the device during operation and making the adjusted welding head 11 more stable. The two ends of the connecting rod 42 are rotatably connected to the slider 41 and the connecting block 38 respectively through a rotating shaft. The rotating shaft 36 drives the screw 39 to rotate, thereby driving the slider 41 to move, which in turn drives the sliding plate 2 to slide along the guide rod 33, thereby allowing the welding head 11 to freely adjust its position, reducing the welding difficulty and improving the welding efficiency of the main body of the device.

[0044] Drive assembly 5 is mounted on the main body 1 of the spot welding machine. Drive assembly 5 includes a drive motor 43 fixedly connected to the main body 1 of the spot welding machine. A second shaft 44 is rotatably connected to the mounting bracket 35 via a bearing. One end of the second shaft 44 is fixedly connected to the output shaft of the drive motor 43. The drive motor 43 is started by program control to drive the second shaft 44 to rotate.

[0045] The docking assembly 6 is mounted on the sliding plate 2. The docking assembly 6 connects the adjusting assembly 4 and the driving assembly 5. The driving assembly 5 drives the single sliding plate 2 to move. The docking assembly 6 includes a helical gear disk 45 fixedly connected to one end of the shaft 36. A helical gear disk 46 slidably connected to the shaft 44 is provided on one side of the helical gear disk 45. A sliding protrusion 47 is fixedly connected to the inner wall of the helical gear disk 46. A sliding groove 48 is provided on the shaft 44. One end of the sliding protrusion 47 is located in the sliding groove 48 and slidably connected to its inner wall. Therefore, rotating the shaft 44 can drive the helical gear disk 46 to rotate. At the same time, the helical gear disk 46 can also slide relative to the shaft 44. The helical gear disk 46 moves relative to the shaft 44 to mesh with the helical gear disk 45. At this time, the drive motor 43 is started, and the helical gear disk 46 drives the helical gear disk 45 to rotate, thereby driving the shaft 36 to rotate.

[0046] A rotating ring 49 is rotatably connected to one side of the helical gear disk 46 via a bearing, and the shaft 44 slides through the rotating ring 49. A groove 51 is provided on the mounting bracket 35. A push rod 52 with one end sliding through the groove 51 is fixedly connected to one side of the rotating ring 49. An elastic rope 53 is fixedly connected between the push rod 52 and the mounting bracket 35. Pushing the push rod 52 causes the helical gear disk 46 to move. At the same time, the elastic rope 53 is stretched by the force to provide self-resetting capability for the helical gear disk 46. Thus, when the operator needs to adjust a welding head 11, the adjustment can be completed by simply moving the corresponding push rod 52 and then starting the drive motor 43. This allows the main body of the device to adjust the position of multiple welding heads 11 separately, which is more flexible and convenient.

[0047] A round rod 54 is slidably connected to the mounting bracket 35. Multiple cylinders 55 are fixedly connected to the round rod 54 at equal intervals. The multiple cylinders 55 are located on one side of multiple push rods 52. Moving the round rod 54 synchronously drives the multiple push rods 52 to move. Thus, the operator can move multiple push rods 52 by pushing the round rod 54, thereby enabling the multiple welding heads 11 of the main body of the device to be adjusted synchronously, improving the applicability of the main body of the device.

[0048] An arc-shaped support block 56 is fixedly connected to the support plate 12, and the workpiece is located inside the arc-shaped support block 56, which facilitates the fixation of the workpiece.

[0049] Example 2

[0050] Please see Figure 1-8 The present invention provides a technical solution: an intelligent automated production equipment for manufacturing and processing automobile mufflers, wherein embodiment 2 is an optimization based on embodiment 1;

[0051] Two friction rollers 57 slide symmetrically on the pallet 12, and an auxiliary component 58 is provided inside the main body 1 of the spot welding machine. The auxiliary component 58 drives the two friction rollers 57 to rotate, so that the workpiece can rotate, thus eliminating the need for the operator to manually rotate the workpiece, which is more convenient and flexible.

[0052] The auxiliary component 58 includes a shaft 59 fixedly connected to the friction roller 57. The shaft 59 is rotatably connected to the spot welding machine body 1 through bearings. Both shafts 59 are fixedly connected to synchronous pulleys 61, which are connected by a synchronous belt. A geared motor 62 is fixedly connected inside the spot welding machine body 1. The output shaft of the geared motor 62 is fixedly connected to one of the shafts 59. The geared motor 62 is started by program control, and the synchronous pulleys 61 and the synchronous belt work together to drive the two friction rollers 57 to rotate.
