Description

Technical Field

[0001] This utility model relates to the field of compressor parts manufacturing equipment, specifically to a compressor connecting rod processing device. Background Technology

[0002] In the compressor manufacturing process, the connecting rod is a critical component, and its welding quality directly affects the compressor's performance and service life. Traditional compressor connecting rod welding methods are mostly manual or semi-automated. Manual welding is not only inefficient, but the welding quality is also greatly affected by the worker's skill level and working condition, making it difficult to guarantee consistent weld quality. While semi-automated welding improves efficiency to some extent, it still suffers from insufficient positioning accuracy and inconsistent connections between processes, resulting in a high product defect rate. With the compressor industry's ever-increasing demands for product quality and production efficiency, developing a high-efficiency automated welding system for compressor connecting rods is of significant practical importance. Utility Model Content

[0003] In view of the above, the purpose of this utility model is to provide a compressor connecting rod processing device to address the problems of the prior art.

[0004] A compressor connecting rod processing device according to this solution is characterized in that it includes:

[0005] The basic support platform has a transverse positioning platform on its surface, which is used to transport cylindrical parts to the welding station along a preset path;

[0006] The ball head conveying device, symmetrically arranged on both sides of the transverse positioning platform, is used to convey the ball head parts to the clamping position;

[0007] The dual-station clamping module is located directly above the two ball head conveying devices and includes two liftable clamping grippers for clamping the ball head parts and lifting them to both ends of the cylindrical parts at the welding station.

[0008] A dual welding torch assembly, comprising two liftable welding torches for welding cylindrical and ball-end parts;

[0009] The support system, located on the transverse positioning platform, is used to provide support for the cylindrical parts and allow them to rotate freely during the welding process.

[0010] The rotary drive mechanism includes a liftable servo motor and a drive wheel connected to the servo motor. When the cylindrical part and the ball head part are in place, the dual welding gun assembly begins the welding operation. During this process, the rotary drive mechanism is activated, the servo motor descends, and the drive wheel makes close contact with the cylindrical part, thereby driving the cylindrical part and the ball head part to rotate relative to the welding gun to achieve the welding operation.

[0011] Furthermore, the transverse positioning platform includes a linear movable rail, a bracket, and a drive cylinder. The bracket is mounted on the linear movable rail, and the drive cylinder is connected to the bracket.

[0012] Furthermore, multiple ball heads are installed on the two claw surfaces of the gripper.

[0013] Furthermore, the support system includes two support rollers.

[0014] Furthermore, a gear transmission system is provided between the servo motor and the drive wheel.

[0015] Beneficial effects: This solution can achieve fully automated production through the cooperation of various components, effectively improving production efficiency. Furthermore, the use of dual welding gun assemblies allows for simultaneous operation and one-time welding. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1 to 2 A compressor connecting rod processing device is shown, characterized in that it includes:

[0021] The basic support platform 100 serves as the foundation for the entire system. Its platform is equipped with a transverse positioning platform 200, which smoothly transports cylindrical parts to specific welding stations. The transverse positioning platform 200 can be composed of a linear movable rail 201, a support 202, and a drive cylinder 203. The support 202 is mounted on the linear movable rail 201, and the drive cylinder 203 is connected to the support 202. The drive cylinder 203 enables the support 202 to quickly achieve rapid work cycles, improving production efficiency. In this embodiment, the support system 600 uses two support rollers 601 to support the cylindrical parts without employing other positioning methods. This is because the cylindrical parts are all-metal constructions, heavy, and therefore sufficiently stable. Rubber sleeves can be added to the surface of the support rollers 601 to increase friction. Of course, besides cylinder drive, screw drive is also an optional solution.

[0022] The ball head conveying device 300 is symmetrically arranged on both sides of the transverse positioning platform 200. This device uses a stepping conveyor belt, which can continuously transport the ball head parts to the designated position for subsequent dual-station clamping component gripping. It should be noted that the stepping conveyor belt needs to be equipped with a fixture to position the ball head.

[0023] The dual-station clamping module is located directly above the two ball head conveying devices 300. It has two independently lifting clamping jaws 400. The two clamping jaws 400 can accurately pick up the ball head parts from the ball head conveying devices 300 and smoothly lift them to both ends of the cylindrical parts at the welding station. Each clamping jaw 400 has multiple ball heads on its jaw surface. In addition to being able to grasp the ball head parts, it can also allow the ball head parts to rotate relative to the clamping jaws 400 to provide a basis for subsequent welding.

[0024] The dual welding gun assembly is set at the welding station on the basic support platform 100. It is equipped with two automated welding guns 500, which can perform welding operations simultaneously.

[0025] The support system 600, which is located on the transverse positioning platform 200, provides stable support for the cylindrical part and ensures that the cylindrical part can rotate freely during the welding process. The support system 600 uses two symmetrically arranged support rollers 601 to effectively reduce friction and vibration during rotation and ensure the smoothness of the cylindrical part's rotation.

[0026] The rotary drive mechanism 700 consists of a liftable servo motor 701 and a drive wheel 702 connected to the servo motor 701. A gear transmission system 703 connects the servo motor 701 and the drive wheel 702, enabling precise speed control and maintaining the stability of the welding system. Once both the cylindrical and ball-head parts are accurately positioned, the dual welding torch 500 begins welding. Simultaneously, the rotary drive mechanism 700 activates, and the servo motor 701 descends, bringing the drive wheel 702 into close contact with the cylindrical part. Subsequently, the servo motor 701 controls the drive wheel 702 to rotate, causing the cylindrical and ball-head parts to rotate relative to the welding torch 500, achieving omnidirectional welding. It should be noted that welding is performed at a single point to connect the cylindrical and ball-head parts, and then the cylindrical and ball-head parts rotate relative to the welding torch 500 to complete the welding process.

[0027] Finally, it should be noted that this application should be equipped with a cylindrical feeding module, which includes a storage unit and a material transfer mechanism linked to it. The material transfer mechanism can be a robotic arm that can grasp the cylinders in the storage unit and transfer them to the transverse positioning platform 200. At the same time, the robotic arm can also move the welded connecting rods away from the transverse positioning platform 200.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
