Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to an air intake pipe positioning mechanism. Background Art

[0002] like Fig.15 As shown, an air intake pipe 1 for use in a car needs to be pre-processed before being installed on the car. Specifically, the air intake pipe 1 is connected to the Fig.16 The connecting pipes 2 shown are combined together according to a predetermined matching angle to obtain Fig.17 The intake pipe pre-processed part 3 is shown. The intake pipe 1 has a first joint end 101 and a first curved pipe section 102 connected to the first joint end 101; the connecting pipe 2 has a second joint end 201 and a second curved 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 plugged together.

[0003] In the prior art, workers generally hold the air intake pipe 1 and the connecting pipe 2 respectively, and then plug the second connecting end 201 and the first connecting end 101 together. However, since the air intake pipe 1 and the connecting pipe 2 each have a unique shape, and the combination of the two must also be in accordance with a predetermined matching angle, this poses a great challenge to manual plugging. Workers often adjust the air intake pipe 1 and the connecting pipe 2 to a suitable posture based on experience before plugging them together. The adjustment process takes a lot of time, and the plugging process is laborious, and the consistency of the plugged products is also poor.

[0004] In addition, when pre-processing the intake pipe, Fig.17 As shown, the second joint end 201 and the first joint end 101 plugged together need to be fastened with a clamp 4. The clamp 4 has a clamp body 401 and a locking member 402 sleeved on the first joint end 101. The clamp body 401 has a locking end 4011. The locking member 402 is threadedly connected to the locking end 401. After the locking end 401 is held, the clamp body 401 is locked by rotating the locking member 402. When performing pre-processing, specifically, the clamp 4 is pre-sleeved on the first joint end 101 of the intake pipe 1 (such as Fig.15 As shown), at this time, the clamp 4 is in an unlocked state, and then the second coupling end 201 of the connecting pipe 2 is manually inserted into the first coupling end 101, and this plug-in state is maintained. After the worker manually holds the locking end 401, the worker holds a certain instrument to rotate the locking piece 402 to lock the clamp body 401, so that the first coupling end 101 and the second coupling end 201 are fastened together.

[0005] The above process of manually locking the clamp 4 requires at least two workers to work together, which has low processing efficiency. In addition, since the worker manually holds the locking end 401, the worker who holds the locking end 401 is easily injured during the process of rotating the locking member 402, which is not safe enough.

[0006] Therefore, it is an urgent need to develop an intake pipe pre-processing device that can improve the intake pipe pre-processing efficiency and product consistency, and it is also an urgent need to provide an intake pipe positioning mechanism for the intake pipe pre-processing device.

[0079] Functions and Effects of the Embodiments

[0080] According to the air intake pipe positioning mechanism involved in this embodiment, because it includes a first positioning mold, a first clamping mold and a first lifting unit, the first positioning mold is adapted to the first curved pipe section and the first joint end, and can place and support the first curved pipe section and the first joint end, so that the first curved pipe section is maintained in the first posture position and the first joint end is oriented in the horizontal direction and arranged opposite to the second joint end, which is convenient for subsequent plugging with the second joint end. 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.

[0081] 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.

[0082] Furthermore, because the air intake pipe positioning mechanism also includes a first positioning mold mounting portion and a first clamping mold mounting portion, the first positioning mold and the first guide rail are arranged on the first positioning mold mounting portion, the first clamping mold mounting portion is arranged on the first movable member, and the first clamping mold is arranged on the first clamping mold mounting portion, such an arrangement can facilitate the clamping cooperation of the first positioning mold and the first clamping mold on the air intake pipe.

[0083] Furthermore, because the first positioning mold mounting portion is provided with a first protrusion and a first groove on one side close to the first clamping mold mounting portion, the first protrusion is arranged at a position higher than the first groove, and the top of the first groove is a blind end, the first clamping mold mounting portion is provided with a second groove and a second protrusion respectively matching the first protrusion and the first groove, the second protrusion is arranged at a position lower than the second groove, and the bottom of the second groove is a blind end, when the first clamping mold moves from the avoidance position to the clamping position, the second groove moves up relative to the first protrusion, and the second protrusion moves up along the first groove until the bottom of the second groove abuts against the first protrusion and the second protrusion abuts against the top of the first groove, such a setting can ensure the accuracy of the rising position of the first clamping mold mounting portion and the first clamping mold, and thereby ensure the reliability of the first positioning mold and the first clamping mold clamping the intake pipe.

[0084] Furthermore, because the first protrusion and the first groove are respectively arranged on both sides of the first guide rail, such an arrangement can ensure the stability of the first clamping mold mounting portion and the lifting and lowering of the first clamping mold.

[0085] Furthermore, because the first positioning mold is also provided with a first arcuate groove adapted to the clamp, and the first arcuate groove is also provided with a lateral abutment portion for the locking end to abut, the first clamping mold is also provided with a second arcuate groove adapted to the clamp, and the second arcuate groove and the first arcuate groove are arranged correspondingly, the clamp can be accommodated by the first arcuate groove and the second arcuate groove, and the clamp can be locked with the help of the lateral abutment portion.

[0086] Furthermore, because the first positioning mold and the first positioning mold mounting portion are integrally formed, and the first clamping mold and the first clamping mold mounting portion are integrally formed, processing, molding and manufacturing are facilitated.

[0087] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
