Description

Technical Field

[0001] This utility model belongs to the field of mechanical assembly technology, specifically relating to a device for disassembling outriggers. Background Technology

[0002] The artillery balancing arm is a critical component of artillery. One end of this component is cylindrical and interference-fitted to the cradle via a key, while the other end has a vertical bend. When disassembling, repairing, or replacing the arm, the arm must be removed from the cradle. Prior to this invention, manual disassembly of the arm relied mainly on traditional methods, using a copper hammer. This method has two drawbacks: First, limited operating space prevents the hammer from striking the front of the arm, leading to uneven axial force and deformation of the mating surfaces of the cradle and arm, affecting subsequent assembly quality. Second, the arm is roughly cylindrical, with only a small flat surface at the head lug, making it difficult to control the hammer's striking position and easily causing irreversible damage to the lug. Furthermore, both methods are time-consuming, averaging 3 hours to disassemble one arm. This method is both time-consuming and labor-intensive, and cannot guarantee the quality of the parts. Utility Model Content

[0003] (a) Technical problems to be solved

[0016] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0017] This embodiment of a device for disassembling a support arm includes the following parts:

[0018] Top plate, guide plate.

[0019] in:

[0020] Figure 1 The top plate is used to generate axial force during outrigger disassembly, which acts on the guide plate. The top plate consists of a top plate body and two bolts. One end of the top plate body is tightly fitted to the mounting surface of the outrigger and cradle, and the other end is tightly fitted to the guide plate. The top plate body is a semi-circular device with a wall thickness of 20mm, and has a threaded hole on each side for mounting the two bolts. Axial force is generated by rotating the bolts, acting on the top plate body.

[0021] Figure 2 This is a guide plate used to transmit the axial force generated by the top plate, which acts on the support arm, causing the support arm to move out slowly. One end of the guide plate is in close contact with the top plate to bear the force, and the other end is in close contact with the support arm. The guide plate is a rectangular irregularly shaped device.

[0022] The connection between the above components is as follows: one end of the top plate body is tightly attached to the mounting surface of the support arm and cradle, and the other end is tightly attached to the guide plate. Two bolts are installed on the top plate body. One end of the guide plate is tightly attached to the top plate to bear the force, and the other end is tightly attached to the support arm. The top plate and the guide plate are welded together.

[0023] The specific working process of this device is as follows:

[0024] First, weld the top plate and guide plate together according to the device structure diagram. Then, install two bolts on the top plate body, ensuring that the bolt thread ends do not extend beyond the plane of the top plate body. Next, press the top plate tightly against the mounting surface of the support arm and cradle, with the thick end of the guide plate pressed against the support arm. Simultaneously, slowly rotate the two bolts, causing them to press against the mounting surfaces of the support arm and cradle. Continue rotating the two bolts to generate axial force, pushing the support arm out. The application of this device can effectively disassemble the support arm, making operation simpler and significantly improving efficiency.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
