Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive parts technology, and more specifically to a cylinder assembly machine. Background Technology
[0002] Shock absorbers are devices that improve ride comfort during vehicle operation. They work by filling the cylinder assembly with fluid, converting vibrations during driving into the fluid's internal energy, thus achieving damping and shock absorption. The cylinder assembly (including the cylinder and bottom valve) is a crucial component of the shock absorber. During the assembly process, the bottom valve is first pressed into the bottom of the cylinder, and then recesses are pressed into the outer walls on both sides of the top of the cylinder to facilitate the positioning of subsequent components. The entire press-fit process includes steps such as loading, centering, positioning, clamping, pressing, recessing, and unloading of the bottom valve assembly and cylinder.
[0003] Currently, cylinder assembly is mainly based on single-piece production. Steps such as feeding, pressing, pressing, and unloading are completed manually at the same station. The degree of integration is not high, and it cannot achieve streamlining, resulting in low assembly efficiency. At the same time, the pressing mechanism and pressing mechanism require human cooperation when they are working, which poses a significant safety hazard. Summary of the Invention

Detailed Implementation
[0030] To facilitate understanding of the present invention, the present invention will be described more fully and in detail below with reference to the accompanying drawings and preferred embodiments, but the scope of protection of the present invention is not limited to the following specific embodiments.
[0031] like Figures 1-10As shown, this embodiment discloses a cylinder assembly machine, including a frame 1 and a rotating clamping device and a pressing device mounted on the frame 1. An operating table 11 is provided on the outer side of the frame 1 for controlling the entire equipment. The rotating clamping device includes a turntable 5 and a turntable 6 that drives the turntable 5 to rotate through the pressing device. The turntable 6 is a cam divider that rotates 90° in sequence. The turntable 21 is circumferentially provided with four bottom valve cylinder clamping mechanisms. The bottom valve cylinder clamping mechanism includes a bottom valve clamping assembly 3 for clamping the bottom valve and a cylinder clamping assembly 4 for clamping the cylinder and aligning it with the bottom valve, thereby facilitating the subsequent pressing and denting of the pressing device. The pressing device includes a cylinder pressing mechanism 7 for pressing the cylinder into the bottom valve and a cylinder denting mechanism 8 for denting the cylinder sidewall. This invention uses a turntable 6 to drive a rotating disk 5 through a pressing device, thus forming multiple workstations. This streamlines the loading, clamping, pressing, denting, and unloading processes at different workstations, ensuring worker safety. The rotating arrangement of multiple workstations on the turntable saves space and facilitates streamlined operations for loading, pressing, denting, and unloading. The pressing and denting processes are automated, improving assembly efficiency. The bottom valve clamping assembly 3 for clamping the bottom valve and the cylinder clamping assembly 4 for aligning the cylinder with the bottom valve further ensures accurate alignment of the bottom valve and cylinder, improving the quality of pressing and denting.
[0032] In this embodiment, the cylinder pressing mechanism 7 includes a cylinder pressing head 71, a pressing head telescopic drive 74, a pressing mounting plate 72, and a mounting plate telescopic drive 73. The pressing head telescopic drive 71 and the mounting plate telescopic drive 73 can be pneumatic cylinders, hydraulic cylinders, or electric push rods. The pressing head telescopic drive 71 is mounted on the pressing mounting plate 72. The cylinder pressing head 71 is mounted on the telescopic end of the pressing head telescopic drive 71. By pressing the upper end of the cylinder downwards through the cylinder pressing head 71, the bottom valve is pressed into the cylinder. The pressing mounting plate 72 is mounted on the telescopic end of the mounting plate telescopic drive 73, thus adapting to pressing operations on cylinders of different heights. Furthermore, the pressing mounting plate 72 is vertically slidably connected to the guide rod in the vertical guide rod assembly 75, thereby ensuring vertical movement accuracy.
[0033] In this embodiment, the cylinder barrel pressing mechanism 8 includes a cylinder barrel retaining seat 81, a pressing assembly 82, a transverse mounting plate 83, a transverse telescopic member 84, a vertical mounting plate 85, and a vertical telescopic member 86. Similarly, the transverse telescopic member 84 and the vertical telescopic member 86 can be pneumatic cylinders, hydraulic cylinders, or electric push rods. The cylinder barrel retaining seat 81 is mounted on the transverse mounting plate 81 and is provided with a cylinder barrel retaining groove 811, which has a U-shaped structure. The pressing assembly 82 is mounted on both sides of the cylinder barrel retaining seat 81. The denting assembly 82 includes a denting head 821 and a denting head extension drive 822 that drives the denting head 821 to dent the side wall of the cylinder within the cylinder groove 811. To ensure the accuracy of the denting head 821, the denting head 821 slides in contact with the inner hole of the cylinder retaining seat 81 and is reset by a denting head return spring. The cylinder retaining seat 81 is mounted on a transverse mounting plate 83. The transverse extension drive 84 drives the cylinder retaining seat 81 on the transverse mounting plate 83 to engage the cylinder. The extension end of the vertical extension drive 86 is connected to the vertical mounting plate 85. Similarly, the vertical mounting plate 85 slides vertically in contact with the guide rod in the vertical guide rod assembly 75, thereby ensuring vertical movement accuracy. During operation, the lateral telescopic component 84 is in a retracted state, providing clearance for the cylinder on the bottom valve cylinder clamping mechanism driven by the turntable 6 to enter the pressing and denting position. After the valve cylinder clamping mechanism is driven to rotate 90° to its position, the lateral mounting plate 83 extends forward under the drive of the lateral telescopic component 84, and the cylinder is inserted into the cylinder slot 811. At this time, the cylinder is pressed into place by the cylinder pressing mechanism 7, and the bottom valve is pressed into the cylinder. Then, the denting head telescopic drive component 822 on both sides drives the tips of the denting heads 821 on both sides to extend into the cylinder slot 811, symmetrically denting the side wall of the cylinder to form a recess. After completion, the lateral telescopic component 84 drives the lateral mounting plate 83 to retract, and the turntable 6 drives the turntable 5 to move the bottom valve cylinder clamping mechanism to the next position.
[0034] In this embodiment, to accommodate the press-fitting of various cylinder barrel and foot valve models, a pre-pressure detection device 9 is also included for cylinder barrel press-fitting. The pre-pressure detection device 9 includes a pre-pressure telescopic component 91, a pre-pressure head 92, and a vertical displacement detection assembly 93 for the vertical displacement of the pre-pressure head 92. The telescopic end of the pre-pressure telescopic component 91 is fixed to the pre-pressure head 92. A tapered positioning hole is provided on the lower side of the pre-pressure head 92, thus forming a downward-facing flared opening. Therefore, on the one hand, the cylinder barrel is pre-pressed and aligned using the pre-pressure head 92. On the other hand, the height position of the cylinder barrel before entering the next work station can also be detected, facilitating the adjustment of relevant parameters of the subsequent press-fitting device.
[0035] In this embodiment, the bottom valve clamping assembly 3 includes a bottom valve positioning sleeve 31 into which the bottom valve can be inserted, and the cylinder clamping assembly 4 includes an elastic clamp 41 for engaging the cylinder to axially align the cylinder and the bottom valve. The elastic clamp 41 is positioned above the bottom valve positioning sleeve 31. After the cylinder is manually pushed into the elastic clamp 41, the elastic clamp 41 automatically clamps the cylinder by its elastic force, without affecting other mechanisms from pressing the cylinder into the bottom valve.
[0036] In this embodiment, the cylinder clamping assembly 4 further includes a guide rod assembly 42. The bottom of the guide rod 421 of the guide rod assembly 42 is mounted on the turntable 1, and the elastic clamp 41 is mounted on the guide rod assembly 42 in a vertically adjustable manner. Specifically, a locking mechanism 422 that can be quickly tightened and loosened is inserted into the guide rod 421, thereby facilitating flexible adjustment of the upper and lower clamping positions while still fixing the vertical position of the elastic clamp 41.
[0037] In this embodiment, the elastic clamp 41 includes a first clamp 411, a second clamp 412, a clamp slider 413, a clamp guide rail 414, a mounting plate 415, a connecting rod 416, a clamp spring 417, a centering slider 418, and a centering guide rail 419. The clamp slider 413 is mounted on the bottom of the first clamp 411 and the second clamp 412. The clamp slider 413 slides with the clamp guide rail 414, so that the first clamp 411 and the second clamp 412 move in parallel. The clamp guide rail 414 and the centering guide rail 419 are mounted on the mounting plate 415 (the locking mechanism 422 is mounted on both sides of the mounting plate 415, and the guide rod 421 passes through the locking mechanism 422 and the mounting plate 415). The clamp guide rail 414 and the centering guide rail 419 are mounted on the mounting plate 415. The connecting rod 416 is arranged on both sides of the centering slider 418, and one end of the connecting rod 416 is hinged to one side of the centering slider 418, and the other end is hinged to the first clamp 411 or the second clamp 412. The two ends of the clamp spring 417 are respectively connected to the first clamp 411 and the second clamp 412, and avoid the clamping position of the first clamp 411 and the second clamp 412. The centering guide rail 419 is set perpendicular to the middle of the clamp guide rail 414. When it is squeezed into the cylinder, the first clamp 411 and the second clamp 412 move away from each other, and the centering slider 418 moves toward the clamp guide rail 414. When the cylinder is removed, the first clamp 411 and the second clamp 412 move relative to each other, and the centering slider 418 moves away from the clamp guide rail 414. The centering slider 418 and the centering guide rail 419 ensure that the center surfaces between the first clamp 411 and the second clamp 412 are fixed, ensuring that the cylinder and the bottom valve are axially aligned. The first clamp 411 and the second clamp 412 are provided with V-grooves 420 facing each other, and the snap-fit input ends of the first clamp 411 and the second clamp 412 are provided with rollers 410 facing each other. This transforms the sliding friction during insertion into rolling friction, avoiding damage to the outer wall of the cylinder.
[0038] In this embodiment, to accommodate foot valves with different outer diameters, the foot valve clamping assembly 3 further includes a mounting base 32 and a positioning element 33. The foot valve positioning sleeve 31 is inserted into the mounting hole 321 of the mounting base 32, and the positioning element 33 is mounted on the mounting base 32 and detachably inserted into the positioning hole of the foot valve positioning sleeve 31. The positioning element 33 can be threaded to the side wall of the mounting base 32, thereby connecting the mounting base 32 and the foot valve positioning sleeve 31 into one unit. The foot valve positioning sleeve 31 can be replaced at any time, resulting in a wider assembly range.
[0039] In this embodiment, considering that the downward pressure of the cylinder pressing mechanism 7 is relatively large, in order to avoid damage to the turntable 5 and the turntable 6 by the off-center load pressure during pressing, a turntable support mechanism 2 is also included. The turntable support mechanism 2 includes a support column 21, a fixed sleeve 22, a support spring 23 and a spring locking cover 24. The support column 21 is fixedly installed on the frame 1, the fixed sleeve 22 is inserted into the turntable 5, the mounting base 32 is vertically slidably connected to the fixed sleeve 22, the spring locking cover 24 is located at the bottom of the fixed sleeve 22 and connected to the bottom of the mounting base 32, the support spring 23 is sleeved on the mounting base 32, and one end of the support spring 23 abuts against the fixed sleeve 22 and the other end abuts against the spring locking cover 24. The opposite ends of the support column 21 and the spring locking cover 24 are provided with inclined surfaces 25 to facilitate mutual compression and cooperation. Therefore, when the bottom valve cylinder clamping mechanism, which clamps the cylinder and the bottom valve, rotates to the bottom of the cylinder lower pressure head 71, the spring locking cover 24 will be squeezed into the support column 21, thereby removing the mounting base 32 from the downward pressure on the fixing sleeve 22 and supporting it on the fixing sleeve 22. When the lower pressure head 71 acts on the cylinder, the downward pressure will be transmitted to the support column 21 through the mounting base 32 and the spring locking cover 24, and finally to the frame 1, thereby avoiding damage to the turntable 5 and the turntable 6 from the downward pressure from the cylinder lower pressure head 71.
[0040] In this embodiment, to prevent the cylinder barrel and foot valve from being missed during installation, a detection sensor 10 for detecting the cylinder barrel and foot valve is provided on one side of the foot valve clamping assembly 3. If the detection sensor 10 fails to detect the foot valve and cylinder barrel before the pressing tool presses down on the cylinder barrel or after the pressing action is completed, the detection sensor 10 will send a feedback signal to automatically alarm.
[0041] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
