Description

Technical Field

[0001] The utility model relates to the field of machinery, and particularly relates to a pre-processing device for an air inlet pipe. Background Art

[0002] As Figure 15 shown, an air inlet pipe 1 used in an automobile needs to be pre-processed before being installed on the automobile. Specifically, the air inlet pipe 1 and a connecting pipe 2 as Figure 16 shown are combined together at a predetermined fitting angle to obtain an air inlet pipe pre-processed part 3 as Figure 17 shown. The air inlet 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 air inlet pipe 1 and the connecting pipe 2 are inserted together.

[0003] In the prior art, generally, a worker holds the air inlet pipe 1 and the connecting pipe 2 respectively, and then inserts the second joint end 201 and the first joint end 101. However, since the air inlet pipe 1 and the connecting pipe 2 each have a unique shape, and the combination of the two must be at a predetermined fitting angle, this poses a great challenge to manual insertion. Workers often adjust the air inlet pipe 1 and the connecting pipe 2 to a suitable posture according to experience before inserting, which takes a long time in the adjustment process, and the insertion process is relatively laborious, and the consistency of the inserted products is also relatively poor.

[0004] In addition, when pre-processing the air inlet pipe, as Figure 17 shown, the inserted second joint end 201 and the 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 air inlet pipe 1 (as Figure 15 shown), 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 inserted state is maintained. After the worker manually abuts the locking end 401, the worker holds a certain instrument to rotate 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 worker manually holds 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 a pre-processing device for intake pipes that can improve the pre-processing efficiency and product consistency of intake pipes. Summary of the Utility Model

[0062] Figure 13It is a schematic structural view of the connecting pipe installation mechanism in the embodiment of the present utility model after removing the second clamping die blank and the second clamping die blank installation part.

[0067] The second clamping die blank 213 is arranged on the second clamping die blank installation part 214 and can lift along the second guide rail 2152 together with the second clamping die blank installation part 214, so as to switch between its clamping position (the position after descending, specifically as Figure 12 shown) and the avoidance position (the position after ascending, not shown in the figure). The second clamping die blank 213 is adapted to the second bent pipe section 202 and is used to clamp the second bent pipe section 202 on the second positioning die blank. As Figure 11 shown, when the second clamping die blank 213 is in its clamping position, the second joint end 201 is exposed, facilitating subsequent insertion with the first joint end 101.

[0068] Figure 14 It is a schematic structural view of the second clamping die blank and the second clamping die blank installation part in the embodiment of the present utility model.

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

[0071] In this embodiment, the second clamping die mounting portion 214 and the second clamping die 213 are integrally formed.

[0072] The working process of the intake pipe preprocessing device 100 is as follows:

At this time, the first bent pipe section 102 is maintained at the first attitude position and the first joint end 101 faces the horizontal direction, the second bent pipe section 202 is maintained at the second attitude position, and the second joint end 201 faces the horizontal direction and is opposite to the first joint end 101.

[0075] Then, the first driving portion 151 drives the first clamping die mounting portion 14 and the first clamping die 13 to move upward to the position where the first clamping die 13 is at its clamping position. At this time, the intake pipe 1 is clamped on the first positioning die 11 by the first clamping die 13; meanwhile, the second driving portion 2151 drives the second clamping die mounting portion 214 and the second clamping die 213 to move downward to the position where the second clamping die 213 is at its clamping position.

The first clamping mold is adapted to the first curved pipe section and the first joint end, and can be moved in the vertical direction under the drive of the first lifting unit, so as to switch between the clamping position and the avoidance position, so as to facilitate placing the air intake pipe on the first positioning mold when it is in the avoidance position, and clamping the air intake pipe on the first positioning mold when it is in the clamping position, so as to facilitate subsequent reliable plugging with the second joint end.

[0082] Furthermore, because the first lifting unit includes a first guide rail, a first movable member and a first driving unit, the first guide rail is extended in the vertical direction; the first movable member is movably disposed on the first guide rail, and the first clamping mold is disposed on the first movable member; the first driving unit can drive the first movable member and the first clamping mold to lift and lower along the first guide rail, thereby facilitating the switching of the first clamping mold between its clamping position and avoidance position.

[0087] 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.

[0088] 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.

[0089] 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.
