[0002] In modern manufacturing, cylinders, as crucial actuators, are widely used in various automated equipment. Currently, existing cylinders on the market often fail to meet performance requirements when high output force is needed and installation space is limited. For example, in some high-precision, compact automated production lines or fixtures, existing cylinders either lack sufficient output force or are too large, making it difficult to meet actual needs. Utility Model Content

By integrating multiple cylinder components into the same integrated cylinder barrel and providing a first air passage and a second air passage, all piston components can retract or extend synchronously. The overall structure is compact, reducing the installation space required. Furthermore, through the interlocking and cooperation of adjacent piston components within the same cylinder assembly—a force-multiplying structure design—a large output force is generated within a relatively small size.

[0032] Reference Figures 1 to 5 As shown, this utility model provides a highly integrated force-multiplying cylinder that can be used in various jigs and automated production lines. It includes an integrated cylinder barrel 1 and multiple cylinder assemblies arranged in parallel within the integrated cylinder barrel 1. The integrated cylinder barrel 1 has multiple rows and columns of inner chambers 2 arranged in an array, and each inner chamber 2 is provided with a piston assembly 3. Each cylinder assembly includes all piston assemblies 3 in the same column, and adjacent piston assemblies 3 are interlocked. The integrated cylinder barrel 1 has a first vent 4 for controlling the retraction of all piston assemblies 3 and a second vent 5 for controlling the extension of all piston assemblies 3.

[0033] The first ventilation channel 4 includes at least one first ventilation port 41 connected to the outside and opened on the side wall of the integrated cylinder 1, at least one first branch air passage 42 opened in the side wall of the integrated cylinder 1 in the vertical direction, and a plurality of first connecting holes 43 for connecting each inner chamber 2; the first connecting holes 43 are opened between the first branch air passage 42 and the nearest inner chamber 2, or are opened in the horizontal direction between two adjacent inner chambers 2.

[0034] In one specific embodiment, the first vent 41 and the first branch air passage 42 are both provided as two; each of the opposite side walls of the integrated cylinder 1 is provided with a first vent 41 and a first branch air passage 42. Simultaneous air intake on both sides can ensure the synchronicity of the piston assembly 3 retraction and improve accuracy.

[0035] The second ventilation channel 5 includes at least one second ventilation port 51 that connects to the outside and is opened on the side wall of the integrated cylinder 1, at least one second branch air passage 52 that is opened in the vertical direction in the side wall of the integrated cylinder 1, and a plurality of second connecting holes 53 for connecting each inner chamber 2; the second connecting holes 53 are opened between the second branch air passage 52 and the nearest inner chamber 2, or are opened in the horizontal direction between two adjacent inner chambers 2.

[0036] In another specific embodiment, the second vent 51 and the second branch air passage 52 are both provided in pairs; each of the opposite side walls of the integrated cylinder 1 is provided with a second vent 51 and a second branch air passage 52. Simultaneous air intake on both sides can ensure the synchronicity of the piston assembly 3 extension and improve accuracy.

[0037] The piston assembly 3 includes a piston 31 disposed in the inner chamber 1 and a piston rod 32 connected to the piston 31; in each cylinder assembly, the uppermost piston assembly 3 extends out from the top of the integrated cylinder 1, so that the uppermost piston assembly 3 in each cylinder assembly can be connected to a lifting rod for use.

[0038] A longitudinal partition 6 is provided between two adjacent inner chambers 2 in the horizontal direction; the first connecting hole 43 and the second connecting hole 53 are both opened on the longitudinal partition 6; the first connecting hole 43 connects to the upper part of the piston 31, and the second connecting hole 53 connects to the lower part of the piston 31.

[0039] In one specific embodiment, the integrated cylinder 1 contains five cylinder assemblies. Each cylinder assembly includes two piston assemblies 3 positioned vertically, corresponding to two adjacent inner chambers 2, which operate independently. When the first air passage 4 is vented, the air flows through the first air inlet 41 and the first branch air passage 42, splitting into two paths that enter the two inner chambers 2 from above the piston 31, causing the piston rod 32 of the piston assembly 3 to retract. When the second air passage 5 is vented, the air flows through the second air inlet 51 and the second branch air passage 52, splitting into two paths that enter the two inner chambers 2 from below the piston 31, causing the piston rod 32 of the piston assembly 3 to extend. Within the same cylinder assembly, the two piston assemblies 3 are coupled and superimposed to achieve simultaneous force application. Under the same air source pressure, the two piston assemblies 3 operate simultaneously, resulting in a force output twice that of a conventional cylinder, driving the piston assembly 3 to reciprocate.
