Description

Technical Field

[0001] The invention relates to the technical field of turbocharger assembly, in particular to a fully automatic positioning and assembling tool for a compressor shell and an intermediate body. Background Art

[0002] Turbocharger products are widely used in automobile engines and are the core components of the engines. They are used under ultra-high speed, high pressure and high speed for a long time, and are accompanied by ultra-high frequency vibration of the engine, which puts forward more stringent assembly quality requirements for turbocharger products, such as the strength of the assembled product, the installation angle with the engine, the choice of boundary connection method, etc., thus putting forward requirements for stable process, strong error-proofing ability and reliability of tooling design.

[0003] The existing method for positioning and assembling the compression shell and the intermediate body is a fully manual assembly, in which the compression shell and the intermediate body are first pre-assembled and the bolts are pre-tightened, and then the pre-assembled compression shell and the intermediate body are manually placed in the tooling, and the positioning mechanism is manually moved, and the bolts are locked after clamping, and then the bolts are tightened. However, during the tightening process, even if the positioning mechanism has been locked, there may still be slight rotation, resulting in an unstable angle. Moreover, since the compression shell is made of aluminum material, and the positioning mechanism in contact with it is made of nylon material, slight rotation will cause wear of the positioning mechanism after long-term use, thereby causing inaccurate positioning. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a fully automatic positioning and assembly tool for a compression shell and an intermediate body which can be assembled accurately, does not cause the intermediate body to rotate during the bolt tightening process, can maintain clamping throughout the process and saves manpower.

[0005] The technical solution adopted by the present invention is: to provide a fully automatic positioning and assembly tool for a compression shell and an intermediate body, which includes a base, a compression shell positioning mechanism, and an intermediate body positioning mechanism. The compression shell positioning mechanism is arranged on the base, and the intermediate body positioning mechanism includes a guide mechanism, a first positioning block, a second positioning block, and a first driving member. The guide mechanism is arranged on the base, the first positioning block and the second positioning block are respectively connected to the guide mechanism, and the first positioning block and the second positioning block are connected through the first driving member.

[0006] After adopting the above structure, the fully automatic positioning and assembly tool for the compression shell and the intermediate body of the present invention has the following advantages compared with the prior art: first, after the pre-assembled compression shell and the intermediate body are placed in the compression shell positioning mechanism, the compression shell positioning mechanism positions the compression shell, and then the intermediate body is positioned by the intermediate body positioning mechanism, and the guide mechanism is used to guide the movement direction of the first positioning block and the second positioning block to ensure that the first positioning block and the second positioning block can correctly position the intermediate body, and the first positioning block and the second positioning block are moved on the guide mechanism by the action of the first driving member to clamp the intermediate body, so that the intermediate body can be adjusted to the required installation angle, ensuring accurate installation; secondly, in the process of tightening the bolts, the first driving member can continuously act on the first positioning block and the second positioning block, so that the intermediate body is continuously subjected to the clamping force, ensuring that the intermediate body will not rotate when the bolts are tightened, ensuring the installation quality; at the same time, the assembly only needs to load and unload materials, and no other adjustments are required during the assembly process, saving manpower and improving work efficiency.

[0007] Preferably, the first driving member is a first cylinder, which can well drive the first positioning block and the second positioning block to move, and maintain air pressure to continuously act on the first positioning block and the second positioning block, so that the intermediate body can be continuously clamped, thereby ensuring assembly accuracy.

[0010] Preferably, the compression shell positioning mechanism includes a third positioning block and a fourth positioning block, both of which are fixedly connected to the base. The third positioning block is used to place the compression shell, and the fourth positioning block is used to provide auxiliary support for the compression shell to ensure that the compression shell does not fall.

Under the action of the second driving member, the fifth positioning block can be pressed tightly against the compression shell to ensure that the compression shell does not rotate.

[0012] Preferably, the first positioning block is provided with an angle detection sensor, which is used to detect the installation angle of the intermediate body to ensure the installation angle is accurate.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] According to the instruction manual Figure 1-3 As shown, the present invention provides a fully automatic positioning and assembly tool for a compression shell and an intermediate body, which includes a base 1, on which a compression shell positioning mechanism and an intermediate body positioning mechanism are arranged, wherein the intermediate body positioning mechanism includes a guiding mechanism, a first positioning block 3.1, and a second positioning block 3.2, the guiding mechanism includes a guide rail 4.3, a first slider 4.1, and a second slider 4.2, the guide rail 4.3 is fixed to the base 1 by bolts, the first slider 4.1, the second slider 4.2 are slidably connected with the guide rail 4.3, the first positioning block 3.1 is connected to the first slider 4.1, the second positioning block 3.2 is connected to the second slider 4.2, and the first positioning block 3.1 and the second positioning block 3.2 are connected through a first driving member 3.3; the compression shell positioning mechanism includes a third positioning block 2.1, a fourth positioning block 2.2, and a second driving member 2.4, the third positioning block 2.1, the fourth positioning block 2.2 and the second driving member 2.4 are respectively connected to the base 1, and a fifth positioning block 2.3 is also arranged on the second driving member 2.4.

[0022] The first driving member 3.3 is driven by the first cylinder, which can well drive the movement of the first positioning block 3.1 and the second positioning block 3.2, and maintain the air pressure to continuously act on the first positioning block 3.1 and the second positioning block 3.2, so that they can continuously clamp the intermediate body 8, ensuring the assembly accuracy.

[0023] The base 1 is also provided with a first limiting mechanism 5.1 and a second limiting mechanism 5.2, wherein the first limiting mechanism 5.1 and the second limiting mechanism 5.2 are both connected to the base 1 by bolts, and the first limiting mechanism 5.1 and the second limiting mechanism 5.2 are respectively arranged on the sides of the two ends of the guide rail 4.3, and the first slider 4.1 is provided with a first limiting protrusion 4.4 matching the first limiting mechanism 5.1, and the second slider 4.2 is provided with a second limiting protrusion 4.5 matching the second limiting mechanism 5.2. The first slider 4.1 can be limited by the cooperation of the first limiting mechanism 5.1 and the first limiting protrusion 4.4, and the second slider 4.2 can be limited by the cooperation of the second limiting mechanism 5.2 and the second limiting protrusion 4.5.

[0024] The surface where the first positioning block 3.1 contacts the intermediate body 8 is its working surface. Angle detection sensors 6 are arranged at both ends of the working surface of the first positioning block 3.1, and can monitor the angle of the intermediate body 8 at the same time. When the angles detected by the two angle detection sensors 6 are the same, it means that the positioning angle of the intermediate body 8 has reached an accurate value. At this time, tightening action can ensure assembly quality.

[0025] The second driving member 2.4 can be driven by a cylinder or a motor. The fifth positioning block 2.3 arranged at the end of the second driving member 2.4 can extend or retract with the second driving member 2.4. The fifth positioning block 2.3 is a pin that can be inserted into the positioning hole on the compression shell 7 to ensure that the compression shell 7 does not rotate during the assembly process. When the positioning hole is not arranged on the compression shell 7, the fifth positioning block 2.3 can be positioned by a raised plane to press the surface of the compression shell 7, which can also prevent it from rotating.

[0026] The third positioning block 2.1 is used to position the center of the compression shell 7. The compression shell 7 can be mounted on the third positioning block 2.1 to position the center of the compression shell 7 and limit the freedom of movement of the compression shell 7 left and right, front and back. The fourth positioning block 2.2 is used to provide auxiliary support for the compression shell 7 to prevent the compression shell 7 from tilting and ensure accurate positioning.

[0027] According to the instruction manual Figure 4-5 As shown, its working principle is that after the compression shell 7 and the intermediate body 8 are pre-assembled, the compression shell 7 is placed in the compression shell positioning mechanism, the center position of the compression shell 7 is positioned by the third positioning block 2.1, the fourth positioning block 2.2 provides auxiliary support for the compression shell 7 to make the compression shell 7 horizontal, the second driving member 2.4 drives the fifth positioning block 2.3 to move, so that it is inserted into the positioning hole of the compression shell 7, and the compression shell 7 is restricted so that it does not rotate. At this time, the first cylinder of the first driving member 3.3 begins to be filled with compressed gas, and drives the first positioning block 3.1 and the second positioning block 3.2 to move. The first positioning block 3.1 and the second positioning block 3.2 are guided by the first slider 4.1, the second slider 4.2 and the guide rail 4.3, and move along the guide rail 4.3. The first positioning block 3.1 and the second positioning block 3.3 .2 move toward the intermediate body 8 respectively under the action of the first driving member 3.3, and any one of them stops after contacting the intermediate body 8, which will not affect the movement of the other side toward the intermediate body 8, until the first positioning block 3.1 and the second positioning block 3.2 clamp the intermediate body 8. After clamping, the two angle detection sensors 6 arranged on the first positioning block 3.1 simultaneously detect the angle signal of the intermediate body 8, and automatically perform the tightening process. Since the first positioning block 3.1 and the second positioning block 3.2 continue to clamp the intermediate body 8, the intermediate body 8 will not loosen during the tightening process, which not only ensures the assembly quality, but also prevents the first positioning block 3.1 and the second positioning block 3.2 from causing friction with the intermediate body 8 and causing loss, further ensuring the subsequent assembly quality.

[0028] The above is an explanation of the preferred embodiments of the present invention, but it cannot be understood as a limitation of the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
