Description

Technical Field

[0001] This utility model relates to the field of shell production and processing technology, specifically to an automatic shell feeding, assembly, and welding production line. Background Technology

[0002] The process of assembling a product's outer protective shell with its internal components. The shell typically refers to the outer casing that encloses the internal parts, serving a protective function. Assembly is the process of connecting multiple components into a complete product according to a specific method and sequence. This process may involve steps such as docking, fixing, and functional testing, with the aim of ensuring that the product's function and appearance meet design requirements. Currently, in the product assembly and welding process, relevant technical personnel are involved in assisted assembly operations. On the one hand, this manual operation is relatively inefficient, and the assembly accuracy is also affected to some extent, failing to meet the needs of modern industrial production. On the other hand, the involvement of relevant technical personnel increases their workload and labor costs.

[0003] Therefore, it is necessary to develop an automated material feeding, assembly, and welding production line for the shell. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding assembly and welding production line for housings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding assembly and welding production line for housings, including a feeding conveyor line, an airtightness testing device installed on one side above the feeding conveyor line, and a pin pressing mechanism installed on one side of the airtightness testing device;

[0006] An assembly welding frame is installed below one side of the pin pressing mechanism, a pressing ring mechanism is installed below one side of the assembly welding frame, a side pin pressing mechanism is installed on one side of the pressing ring mechanism, and a finished product conveyor line is installed on one side of the side pin pressing mechanism.

[0007] Preferably, a carrier elevator is installed on one side of the outer wall of the feeding conveyor line, and a feeding robotic arm is installed on the other side of the feeding conveyor line.

[0008] Preferably, a pin feeding mechanism is installed above the pin pressing mechanism, and a material unloading robotic arm is installed in front of the assembly welding frame.

[0009] Preferably, a bushing feeding mechanism is installed below the other side of the assembly welding frame, and a crank feeding mechanism is installed above the bushing feeding mechanism.

[0010] Preferably, a positioner feeding mechanism is installed above the crank feeding mechanism, and a bushing pressing mechanism is installed at the rear end of the internal center position of the assembly welding frame.

[0011] Preferably, a crank welding robotic arm is installed on one side of the assembly and welding frame, and a welding positioning mechanism is installed at the front end of the center position inside the assembly and welding frame.

[0012] Preferably, a ring feeding mechanism is installed at the rear end of the pressing ring mechanism, and a side pin feeding mechanism is installed at the rear end of the side pin pressing mechanism.

[0013] Preferably, a safety fence is installed around the assembly and welding frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By integrating the airtightness testing function of cast iron parts, pins are automatically pressed into the cast iron parts, and the pressing curve and data are monitored and stored in real time. Then, bushings, cranks and positioners are assembled. After assembly, welding is performed. Finally, the pressing ring and side pins are assembled and transferred to the finished product conveyor line. The conveyor line transports the products to the end of the production line, where they are packaged manually. This realizes the automation of material feeding, assembly and welding of the entire production line. At the same time, this technology integrates eight assembly and processing processes, reducing the number of operators from eight to one, which greatly reduces labor costs. The use of robotic arms for transfer minimizes assembly errors caused by human factors, improves assembly accuracy, and greatly improves production efficiency through automated production.

[0026] Working Principle: This technology utilizes an assembly line for turbocharger intermediate housings. Manual personnel place the intermediate housings onto the airtightness testing equipment 4, activate the switch, and the equipment begins airtightness testing. When the equipment detects an abnormality, the human-machine interface and a yellow indicator light will sound an alarm. The manual personnel remove the workpiece and place it in the defective product area. Good products are manually placed into the intermediate housing carrier. Once the carrier is full, it is placed onto the loading conveyor line 1. The loading conveyor line 1 moves the carrier to a designated position, where a loading robotic arm 3 grips the part. The robotic arm 3 is equipped with grippers and fiber optic sensors to facilitate sensing and judgment during workpiece gripping. After the loading robotic arm 3 has finished grabbing all the workpieces on the carrier, the carrier lift 2 transfers the empty carrier to the lower working conveyor of the loading conveyor line 1, returning the carrier to the initial area. The carrier lift 2 then lifts the empty carrier to the upper working conveyor line. The loading robotic arm 3 places the workpieces onto the fixed carrier of the pin pre-installation mechanism. The pin feeding mechanism 6 uses sensors to detect when the workpiece is clamped and pre-installs the pins onto the workpiece. After pre-installation, a cylinder is used to transfer the fixed carrier to the corresponding position of the pin pressing mechanism 5 to begin pressing. During pressing, the human-machine interface displays and records the pressure curve in real time. After pressing is completed, the loading robotic arm 3... Arm 3 transfers the semi-finished component to the fixed carrier of the bushing pressing mechanism 74, pre-installs the bushing, and then the crank welding robot arm 75 picks up the crank from the fixed position of the crank feeding mechanism 72. The bushing pressing mechanism 74 presses the bushing into place, the crank supporting mechanism supports and positions the crank, the loading robot retracts, the crank supporting mechanism pushes the crank into place, and the unloading robot arm 8 transfers the assembled semi-finished product to the welding positioning mechanism 76. The positioning feeding mechanism 73 automatically feeds the material to the fixed position below the welding positioning mechanism 76, and the crank welding robot arm 75 begins welding. After completion, the unloading robot arm 8 transfers the assembled semi-finished product to the pressing mechanism 76. On the positioning carrier of the ring assembly mechanism 9, the ring feeding mechanism 10 automatically feeds the ring to the pressure head of the workpiece. The pressing ring mechanism 9 presses the ring into place. The unloading robot arm 8 transfers the assembled semi-finished product to the positioning carrier of the side pin pressing mechanism 12. The side pin feeding mechanism 11 automatically feeds the side pin to the pressing position. The side pin pressing mechanism 12 starts working and presses the side pin into place. After pressing, the unloading robot arm 8 transfers the finished product to the finished product conveyor line 13. The finished product conveyor line 13 conveys the finished product to the end of the line, where it can be packaged manually. The entire system is surrounded by a safety fence 14 to ensure the safety of the operators.
