Description

Technical Field

[0001] The utility model relates to the field of machinery, and particularly relates to a connecting pipe installation mechanism. Background Art

[0002] As Figure 15 shown, an intake pipe 1 used in an automobile needs to be pre-processed before being installed on the automobile. Specifically, the intake pipe 1 and a connecting pipe 2 as shown in Figure 16 are combined together at a predetermined mating angle to obtain a pre-processed intake pipe 3 as shown in Figure 17 . The intake pipe 1 has a first joint end 101 and a first bent pipe section 102 connected to the first joint end 101; the connecting pipe 2 has a second joint end 201 and a second bent pipe section 202 connected to the second joint end 201. During pre-processing, the second joint end 201 needs to be inserted into the first joint end 101 so that the intake pipe 1 and the connecting pipe 2 are inserted together.

[0003] In the prior art, generally, workers hold the intake pipe 1 and the connecting pipe 2 respectively by hand, and then insert the second joint end 201 and the first joint end 101. However, since both the intake pipe 1 and the connecting pipe 2 have unique shapes, and the combination of the two must be at a predetermined mating angle, this poses a great challenge to manual insertion. Workers often adjust the intake pipe 1 and the connecting pipe 2 to a suitable posture according to experience before inserting, which takes a lot of time in the adjustment process, and the insertion process is quite laborious, and the consistency of the inserted products is also relatively poor.

[0004] In addition, during the pre-processing of the intake pipe, as shown in Figure 17 , the inserted second joint end 201 and first joint end 101 also need to be fastened with a clamp 4. The clamp 4 has a clamp body 401 sleeved on the first joint end 101 and a locking member 402. The clamp body 401 has a locking end 4011, and the locking member 402 is threadedly connected to the locking end 401. After the locking end 401 is abutted, the clamp body 401 is locked by rotating the locking member 402. During pre-processing, specifically, the clamp 4 is first pre-sleeved on the first joint end 101 of the intake pipe 1 (as shown in Figure 15 ), at this time, the clamp 4 is in an unlocked state, then the second joint end 201 of the connecting pipe 2 is manually inserted into the first joint end 101, and this insertion state is maintained. After the worker manually abuts the locking end 401, the worker holds a certain instrument and rotates the locking member 402 to lock the clamp body 401, so that the first joint end 101 and the second joint end 201 are fastened together.

[0005] The above process of manually locking the clamp 4 requires at least two workers to work together, resulting in low processing efficiency. Moreover, since the workers manually hold the locking end 401, the worker holding the locking end 401 is prone to injury during the process of rotating the locking member 402, which is not safe enough.

[0006] Therefore, it has become an urgent need to develop an intake pipe preprocessing device that can improve the preprocessing efficiency and product consistency of the intake pipe, and it has also become an urgent need to provide a connecting pipe installation mechanism for the intake pipe preprocessing device.

The supporting area of ​​the second positioning mold 211 for the second curved pipe section 202 is greater than half of the outer peripheral surface area of ​​the second curved pipe section 202.

[0064] Figure 13 It is a structural schematic diagram of the connecting pipe installation mechanism in the embodiment of the utility model after removing the second clamping mold and the second clamping mold installation part.

[0065] like Figure 10 and Figure 13 As shown, the second lifting unit 215 includes a second guide rail 2152 , a second moving member 2153 and a second driving part 2151 .

Figure 12 The second clamping mold 213 is adapted to the second curved pipe section 202 and is used to clamp the second curved pipe section 202 on the second positioning mold. Figure 11 As shown, when the second clamping mold 213 is in its clamping position, the second coupling end 201 is exposed to facilitate subsequent plugging with the first coupling end 101.

[0070] Figure 14It is a schematic structural view of the second clamping die blank and the second clamping die blank mounting part in the embodiment of the present utility model.

[0071] As Figures 10 - 14 shown, on one side of the second positioning die blank mounting part 211 close to the second clamping die blank mounting part 214, there are an upper positioning groove 2121 and a lower blocking part 2122.

When the second clamping die blank 214 moves down to the clamping position, the upper convex part 2141 abuts against the upper positioning groove 2121 and the lower abutting part 2142 abuts against the lower blocking part 2122.

[0073] In this embodiment, the second clamping die blank mounting part 214 and the second clamping die blank 213 are integrally formed.

[0074] The working process of the intake pipe preprocessing device 100 is as follows:

[0075] The initial state of the intake pipe preprocessing device 100 is as Figure 1 shown. The first clamping die blank 13 and the second clamping die blank 213 are respectively located at their respective avoidance positions, and the connecting pipe installation mechanism 20 is in a position far from the intake pipe positioning mechanism 10.

[0076] First, manually place the intake pipe 1 on the first positioning die blank 11 and place the connecting pipe 2 on the second positioning die blank 211. At this time, the first bent pipe section 102 is kept at the first posture position and the first joint end 101 faces the horizontal direction. The second bent pipe section 202 is kept at the second posture position, and the second joint end 201 faces the horizontal direction and is opposite to the first joint end 101.

[0077] Then, the first driving part 151 drives the first clamping die blank mounting part 14 and the first clamping die blank 13 to move up to the first clamping die blank 13 being in its clamping position. At this time, the intake pipe 1 is clamped by the first clamping die blank 13 on the first positioning die blank 11. At the same time, the second driving part 2151 drives the second clamping die blank mounting part 214 and the second clamping die blank 213 to move down to the second clamping die blank 213 being in its clamping position. At this time, the connecting pipe 2 is clamped by the second clamping die blank 213 on the second positioning die blank 211.

[0078] Next, the third driving part 221 drives the connecting pipe fixing part 21 to move as a whole along the third track 222 in the direction close to the intake pipe positioning mechanism 10, so that the second joint end 201 of the connecting pipe 2 is inserted into the first joint end 101 of the intake pipe 1. The state at this time is asFigure 2 shown.

[0079] Then, the person holds the instrument and applies force inward to make the locking end 4011 abut against the abutting portion 1111 , and rotates the locking member 402 to lock the clamp 4 .

[0080] Finally, the air intake pipe pre-processing device 100 is reset to its initial state, and the pre-processed air intake pipe pre-processed part 3 is manually removed.

[0081] Functions and Effects of the Embodiments

[0082] According to the connecting pipe installation mechanism involved in this embodiment, because it includes a connecting pipe fixing part and a connecting pipe moving part, the connecting pipe fixing part can fix the connecting pipe, and includes a second positioning mold, the second positioning mold is adapted to the second bent pipe section, and can place and support the second bent pipe section so that the second bent pipe section is maintained in a second posture position. At this time, the second coupling end faces the horizontal direction and is opposite to the first coupling end of the intake pipe. The connecting pipe moving part can make the connecting pipe fixing part move horizontally, so that the second coupling end of the connecting pipe fixed on the connecting pipe fixing part can be inserted into the first coupling end of the intake pipe.

[0083] Furthermore, because the connecting pipe fixing portion also includes a second clamping mold and a second lifting unit, the second clamping mold is adapted to the second bent pipe section and can be moved in the vertical direction under the drive of the second lifting unit, so that the second clamping mold can be switched between a clamping position and an avoidance position. When it is in its avoidance position, it is convenient to prevent the connecting pipe from being on the second positioning mold. When it is in its clamping position, the second bent pipe section can be clamped on the second positioning mold, thereby facilitating the subsequent plug-in of the second combining end with the first combining end.

[0084] Furthermore, because the connecting tube moving part includes a third guide rail, a third moving part and a third driving part, the third guide rail is extended in the horizontal direction; the third moving part can be moved horizontally along the third guide rail under the drive of the third driving part, and the connecting tube fixing part is arranged on the third moving part. Such an arrangement facilitates the plugging of the second connecting end and the first connecting end.

[0085] Furthermore, because the third driving part includes a third cylinder, the third cylinder is arranged at the end of the third guide rail away from the air inlet pipe, which facilitates the driving of the third moving member so that it moves horizontally along the third guide rail.

[0086] Furthermore, because the second lifting unit includes a second guide rail, a second movable member and a second driving unit, the second clamping mold is arranged on the second movable member, and the second driving unit can drive the second movable member and the second clamping mold to lift and lower along the second guide rail, thereby realizing the switching of the second clamping mold between its clamping position and avoidance position.

[0087] Further, since the connecting pipe fixing portion further includes a second positioning die mounting portion and a second clamping die mounting portion, the second positioning die is disposed on the second positioning die mounting portion, the second clamping die mounting portion is connected to the second moving member, the second clamping die is disposed on the second clamping die mounting portion, and the second clamping die mounting portion can be lifted and lowered along the second guide rail under the drive of the second driving portion. Such a setting can facilitate the clamping cooperation of the second positioning die and the second clamping die on the connecting pipe.

[0088] Further, since an upper positioning groove and a lower blocking portion are provided on one side of the second positioning die mounting portion close to the second clamping die mounting portion, the upper positioning groove and the lower blocking portion are respectively disposed on both sides of the second guide rail, and an upper convex portion and a lower abutting portion that respectively cooperate with the upper positioning groove and the lower blocking portion are provided on the second clamping die mounting portion. When the second clamping die moves down to the clamping position, the upper convex portion abuts against the upper positioning groove and the lower abutting portion abuts against the lower blocking portion. Such a setting can ensure the accuracy of the downward movement position of the second clamping die mounting portion and the second clamping die, and further ensure the reliability of the clamping of the second positioning die and the second clamping die on the connecting pipe.

[0089] Further, since the third guide rail is provided as two parallel ones, the third moving member is movably disposed on the two third guide rails, ensuring the reliability of the movement of the third moving member.

[0090] Further, since the second positioning die and the second positioning die mounting portion are integrally formed, and the second clamping die mounting portion and the second clamping die are integrally formed, it is convenient for processing and manufacturing.

[0091] Further, since the supporting area of the second positioning die for the second bent pipe section is larger than half of the outer peripheral surface area of the second bent pipe section, it is convenient to realize the reliable support of the second positioning die for the connecting pipe.
