Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, specifically to an automotive exhaust pipe assembly device. Background Technology

[0002] In the mass production of automotive exhaust pipes, a large number of exhaust pipe components need to be assembled through welding processes. However, relying on manual welding operations can no longer meet production needs. Now, many automotive parts manufacturers use robots to complete efficient and precise welding processes. To adapt to the welding operations of robots, special welding fixtures are required.

[0003] like Figure 4 The diagram shows an exhaust pipe 37, which has several sections of pipe body of different sizes. A mounting plate 38 is welded onto each pipe body, and screw holes 39 are provided on the mounting plate 38. The exhaust pipe 37 can be fixed to the vehicle body via the mounting plate 38. Currently, the assembly of this type of exhaust pipe suffers from inconvenient installation and poor stability, making it unsuitable for large-scale welding operations. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides an automobile exhaust pipe assembly device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An automotive exhaust pipe assembly device includes a base, a first support fixed to one end of the base, a first positioning mechanism for positioning the end face of the exhaust pipe mounted on the first support, a second support fixed to the front of the base on one side of the first support, a third support fixed to the rear of the second support, the top surface of the second support having an arc-shaped groove for supporting the exhaust pipe, and a first clamping mechanism mounted on the third support; a fourth support fixed to the base on one side between the second and third supports, the fourth support mounting a second clamping mechanism and a second positioning mechanism; a fifth support and a sixth support fixed to the end of the base away from the first support, the fifth support mounting a third clamping mechanism, and the sixth support mounting a fourth clamping mechanism and a supporting mechanism; and a seventh support also provided on one side of the base of the second support, the height of the seventh support being lower than the height of the second support.

[0007] Preferably, the first positioning mechanism includes a first cylinder that is inclinedly mounted on a first support and a first positioning rod connected to the telescopic end of the first cylinder.

[0008] The above technical solution controls the extension of the first cylinder, which drives the first positioning rod to move obliquely upward, thereby enabling the first positioning rod to be inserted into the end of the exhaust pipe and to position the end of the exhaust pipe.

[0009] Preferably, the first pressing mechanism includes a second cylinder mounted on the bottom surface of the third support, a first support rod connected to the top surface of the third support, a first pressure rod movably connected to the telescopic end of the second cylinder, a first connecting rod movably connected to the first pressure rod, and a first pressing block connected to the bottom surface of the first pressure rod. The first connecting rod is movably connected to the first support rod, the bottom surface of the first pressing block is arc-shaped, and the first pressing block is located above the second support.

[0010] The above technical solution involves placing the head of the exhaust pipe on the arc-shaped groove of the second support, then controlling the extension of the second cylinder to push the first pressure rod. Under the action of the first connecting rod, the first pressure rod rotates toward the exhaust pipe until the first pressure block presses the exhaust pipe onto the second support.

[0011] Preferably, the second positioning mechanism includes a fourth cylinder mounted on the fourth support, a first connecting rod connected to the telescopic end of the fourth cylinder and positioned vertically, and a second positioning rod connected to the two first connecting rods. The second positioning rod passes through the fourth support and is slidably connected to the fourth support. The second pressing mechanism includes a third cylinder mounted on the bottom surface of the fourth support, a second support rod connected to the top surface of the fourth support, a second pressure rod movably connected to the telescopic end of the third cylinder, and a second connecting rod movably connected to the second pressure rod. The second connecting rod is movably connected to the second support rod. The third cylinder is arranged horizontally, and the second pressure rod is arranged vertically and located on one side of the fourth support.

[0012] In the above technical solution, after the exhaust pipe is placed on the seventh support, the mounting plate is placed against the exhaust pipe and the screw hole is aligned with the second positioning rod. Then, the fourth cylinder is controlled to extend, driving the first connecting rod to move forward until the second positioning rod is inserted into the screw hole, thereby positioning the mounting plate. Then, the third cylinder is controlled to extend, driving the second pressure rod to rotate backward until the second positioning rod contacts the second pressure rod, preventing the second positioning rod from moving forward excessively and making the mounting plate contact the pipe body so that the mounting plate can be welded to the pipe body.

[0013] Preferably, the third pressing mechanism includes a fifth cylinder mounted on the bottom surface of the fifth support, a third support rod connected to the top surface of the fifth support, a third pressure rod movably connected to the telescopic end of the fifth cylinder, a third connecting rod movably connected to the third pressure rod, and a second pressing block connected to the bottom surface of the third pressure rod. The third connecting rod is movably connected to the third support rod, the bottom surface of the second pressing block is arc-shaped, and the second pressing block is located above the fifth support.

[0014] In the above technical solution, the tail end of the exhaust pipe is placed on the fifth support, and then the fifth cylinder is controlled to extend, driving the third pressure rod to rotate downward, so that the second pressure block presses the exhaust pipe tightly onto the fifth support.

[0015] Preferably, the fourth pressing mechanism includes a sixth cylinder mounted on the bottom surface of the sixth support, a fourth support rod connected to the top surface of the sixth support, a fourth pressure rod movably connected to the telescopic end of the sixth cylinder, a fourth connecting rod movably connected to the fourth pressure rod, and a third pressure block connected to the bottom surface of the fourth pressure rod. The fourth connecting rod is movably connected to the fourth support rod, and the bottom surface of the third pressure block is arc-shaped. The bearing mechanism includes a seventh cylinder mounted on the sixth support, a second connecting rod connected to the telescopic end of the seventh cylinder, and a sliding rod connected to the two second connecting rods. The sliding rod passes through the sixth support, and the end through which it passes is connected to a bearing plate. The sliding rod is slidably connected to the sixth support, the top surface of the bearing plate is arc-shaped, and the third pressure block is located above the bearing plate.

[0016] In the above technical solution, after the tail of the exhaust pipe is fixed on the fifth support, the end of the exhaust pipe extends obliquely upward. At this time, the seventh cylinder is controlled to retract, which drives the second connecting rod to move forward and backward, thereby driving the two sliding rods to slide forward until the bearing plate is above the end of the exhaust pipe to support the end of the exhaust pipe. Then, the sixth cylinder is controlled to extend, which drives the fourth pressure rod to rotate downward, and the end of the exhaust pipe is pressed tightly onto the bearing plate by the third pressure block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The first positioning mechanism positions the head end of the exhaust pipe, the second clamping mechanism presses the front part of the exhaust pipe onto the second support, the seventh support further supports the front part of the exhaust pipe, the third clamping mechanism and the second positioning mechanism work together to support the mounting plate and make the mounting plate contact the exhaust pipe, the fourth clamping mechanism presses the tail end of the exhaust pipe onto the sixth support, and the fifth clamping mechanism presses the end of the exhaust pipe onto the bearing mechanism, thereby fixing each part of the exhaust pipe individually and keeping each part stable for subsequent welding or assembly.

[0027] A second support 3 is fixed to the front of the first support on the base 1, and a third support 4 is fixed to the rear of the second support 3. The top surface of the second support 3 is provided with an arc-shaped groove for supporting the exhaust pipe. A first pressing mechanism is installed on the third support 4. The first pressing mechanism includes a second cylinder 11 installed on the bottom surface of the third support, a first support rod 12 connected to the top surface of the third support, a first pressure rod 13 movably connected to the telescopic end of the second cylinder, a first connecting rod 14 movably connected to the first pressure rod, and a first pressing block 15 connected to the bottom surface of the first pressure rod. The first connecting rod 14 is movably connected to the first support rod 12. The bottom surface of the first pressing block 15 is arc-shaped and the first pressing block 15 is located above the second support 3.

[0028] A fourth support 5 is fixed to one side of the base 1 between the second and third supports. A second pressing mechanism and a second positioning mechanism are installed on the fourth support 5. The second positioning mechanism includes a fourth cylinder 20 mounted on the fourth support, a first connecting rod 21 vertically connected to the telescopic end of the fourth cylinder, and a second positioning rod 22 connected to the two first connecting rods. The second positioning rod 22 passes through the fourth support 5 and is slidably connected to the fourth support 5. The second pressing mechanism includes a third cylinder 16 mounted on the bottom surface of the fourth support, a second support rod 17 connected to the top surface of the fourth support, a second pressure rod 18 movably connected to the telescopic end of the third cylinder, and a second connecting rod 19 movably connected to the second pressure rod. The second connecting rod 19 is movably connected to the second support rod 17. The third cylinder 16 is horizontally positioned, and the second pressure rod 18 is vertically positioned and located on one side of the fourth support 5.

[0029] A fifth support 6 is fixed to one end of the base 1 away from the first support, and a third pressing mechanism is installed on the fifth support 6. The third pressing mechanism includes a fifth cylinder 23 installed on the bottom surface of the fifth support, a third support rod 24 connected to the top surface of the fifth support, a third pressure rod 25 movably connected to the telescopic end of the fifth cylinder, a third connecting rod 26 movably connected to the third pressure rod, and a second pressing block 27 connected to the bottom surface of the third pressure rod. The third connecting rod 26 is movably connected to the third support rod 24, the bottom surface of the second pressing block 27 is arc-shaped, and the second pressing block 27 is located above the fifth support 6.

[0030] A seventh support 8 is also provided on one side of the second support 3 on the base 1. The height of the seventh support 8 is lower than that of the second support 3, and the front of the exhaust pipe is further supported by the seventh support.

[0031] The working principle of this embodiment is as follows:

[0032] The head of the exhaust pipe 37 is placed on the arc-shaped groove of the second support 3, and the exhaust pipe is supported by the seventh support. Then, the first cylinder 9 is extended, driving the first positioning rod 10 to move obliquely upward, so that the first positioning rod 10 is inserted into the end of the exhaust pipe 37 to position the end of the exhaust pipe. Then, the second cylinder 11 is extended, pushing the first pressure rod 13 to rotate toward the exhaust pipe until the first pressure block 15 presses the exhaust pipe onto the second support 3. Then, the mounting plate 38 is placed against the exhaust pipe 37, and the screw hole 39 is aligned with the second positioning rod 22. The fourth cylinder 20 is then extended, causing the first connecting rod 21 to move forward until the second positioning rod 22 is inserted into the screw hole 39. The two second positioning rods 22 prevent the mounting plate from rotating, thus positioning the mounting plate 38. The third cylinder 16 is then extended, causing the second pressure rod 18 to rotate backward until the second positioning rod 22 contacts the second pressure rod 18, preventing excessive forward movement of the second positioning rod 22. This allows the mounting plate 38 to contact the exhaust pipe 37, facilitating welding the mounting plate to the pipe body. The tail end of the exhaust pipe is then placed on the fifth support 6. The fifth cylinder 23 is then extended, causing the third pressure rod 25 to rotate downward, causing the second pressure block 27 to press the exhaust pipe firmly against the fifth support, thus completing the fixation of the exhaust pipe and the mounting plate.

[0033] Example 2

[0034] Based on Embodiment 1, a sixth support 7 is fixed on the base 1 near the fifth support 6. The sixth support is equipped with a fourth pressing mechanism and a bearing mechanism.

The fourth connecting rod 31 is movably connected to the fourth support rod 29, and the bottom surface of the third pressure block 32 is arc-shaped. The bearing mechanism includes a seventh cylinder 33 mounted on the sixth support, a second connecting rod 34 connected to the telescopic end of the seventh cylinder, and a sliding rod 35 connected to the two second connecting rods. The sliding rod 35 passes through the sixth support 7, and the end through which it passes is connected to a bearing plate 36. The sliding rod 35 is slidably connected to the sixth support 7. The top surface of the bearing plate 36 is arc-shaped, and the third pressure block 32 is located above the bearing plate 36.

[0035] After the tail of the exhaust pipe 37 is fixed on the fifth support 6, the end of the exhaust pipe 37 extends obliquely upward. At this time, the seventh cylinder 34 is controlled to retract, which drives the second connecting rod 34 to move back and forth, thereby driving the two sliding rods 35 to slide forward until the bearing plate 36 is above the end of the exhaust pipe to support the end of the exhaust pipe. Then, the sixth cylinder 28 is controlled to extend, which drives the fourth pressure rod 30 to rotate downward, and the end of the exhaust pipe is pressed tightly onto the bearing plate 36 by the third pressure block 32.
