Description

Equipment and method for assembling balance cylinder Technical Field The invention relates to the technical field of mechanical assembly, in particular to special equipment for assembling a balance cylinder and an assembling method thereof. Background A balancing cylinder is a hydraulic or pneumatic component widely used in industrial equipment (e.g., injection molding machines, die casting machines) for providing a balancing force or cushioning effect, and typically includes a cylinder body, a preload spring, and an end cap for sealing the spring. In the prior art, the assembly of the balance cylinder is mostly dependent on manual operation, and the specific process is that the cylinder body is vertically fixed, then the spring is vertically pressed into the cylinder body by manpower or a simple tool, and finally the end cover is assembled in place to seal the spring. The traditional vertical assembly mode has the defects that firstly, the spring is easy to deflect under the dead weight and compression state, so that the assembly is difficult, even the inner wall of the spring or a cylinder body is damaged, secondly, for a large or pretightening force-large balance cylinder, manual press-fitting is required to consume huge physical force, the efficiency is low, potential safety hazards exist, and finally, the consistency of the product quality is difficult to ensure through manual assembly, key parameters such as press-fitting depth, pretightening force and the like are difficult to accurately control, and the performance and the service life of the balance cylinder are influenced. Therefore, there is a need to develop an automated or semi-automated balance cylinder assembly apparatus that is efficient, stable and reduces labor intensity. Disclosure of Invention The invention aims to overcome the defects of low efficiency, high labor intensity, unstable assembly quality and the like of the manual assembly of the existing balance cylinder, and provides balance cylinder assembly equipment and an assembly method thereof, wherein the balance cylinder assembly equipment has a compact structure and is simple and convenient to operate and can realize horizontal press mounting. In order to achieve the above purpose, the invention adopts the following technical scheme: In a first aspect, the present invention provides an assembly apparatus for a balancing cylinder. The apparatus includes: The installation long platform is used as a basic platform of the whole equipment; The mounting frame is fixedly arranged on the mounting long table and is used for horizontally supporting and positioning a balance cylinder body to be assembled; the locking mechanism is arranged on the mounting frame and used for selectively locking or releasing the cylinder body to ensure the stability of the cylinder body in the assembly process; The lifting support mechanism is arranged on the mounting long table and positioned on a first side (for example, the left side) of the mounting frame and is used for bearing a spring and accurately lifting the spring to a height position coaxial with the central axis of the inner cavity of the cylinder body; The press-fit mechanism is arranged on the mounting long table and is adjacent to the lifting support mechanism and is used for horizontally pressing the spring cover into the port of the cylinder body so as to encapsulate the spring; And the guide rod mechanism is arranged on the installation long table and is positioned on a second side (such as the right side) of the installation frame, which is opposite to the first side, and the guide rod mechanism can horizontally stretch and retract and is used for stretching into the inner cavity of the cylinder body when the spring is assembled, so that accurate guide is provided for feeding the spring, and deflection or clamping stagnation of the spring is prevented. The press mounting mechanism, the lifting supporting mechanism, the mounting rack and the guide rod mechanism are sequentially arranged along the length direction of the mounting long table, and the press mounting mechanism is reasonable in layout and clear in streamline. Preferably, the locking mechanism includes a horizontally movable locking pin. The locking pin can be inserted into a positioning hole or a clamping groove on the side wall of the cylinder body to realize locking when the locking pin advances, and can be withdrawn from the hole groove to release the cylinder body when the locking pin retreats. The structure is simple and reliable. Preferably, the press-fitting mechanism is a hydraulic cylinder. The end of the piston rod of the oil hydraulic cylinder is provided with a special assembly part (such as a threaded joint, a clamping groove and the like) for quickly installing and fixing the spring cover. The oil hydraulic cylinder can provide stable and strong press-fitting force. Furthermore, in order to prevent the oil hydraulic cylinder from accidentally backing back due to sys
