Description

Technical Field

[0001] This utility model relates to the field of pneumatic component manufacturing technology, and in particular to a material handling device for cylinder production. Background Technology

[0002] As a core actuator in fluid transmission and control systems, cylinders are widely used in various mechanical equipment and automation systems. The reliability of cylinder performance, especially the airtightness of its internal chamber and piston rod, is a key indicator of cylinder quality. Insufficient airtightness leads to internal or external leakage, causing not only energy loss and reduced efficiency but also directly affecting the cylinder's output force, speed stability, and even causing the entire system to malfunction. Therefore, rigorous and efficient airtightness testing is an essential step in cylinder manufacturing.

[0003] Currently, dedicated airtightness testing equipment is commonly used in the final inspection or process inspection stages of cylinder production. A typical existing testing procedure is as follows: Workers hold the cylinder body to be tested, manually aligning and pressing the specific end to be tested onto the inspection component of the testing equipment. After a temporary seal is formed between the component and the cylinder port, the equipment injects test gas at a certain pressure into the cylinder. Airtightness is then determined by monitoring pressure changes or flow rates. After the test is completed, the cylinder is removed, and the same procedure is repeated for the next cylinder to be tested.

[0004] However, the existing equipment and workflow described above have significant drawbacks in practice, primarily due to their heavy reliance on manual operation, high labor intensity, and low efficiency. Operators need to repeatedly perform actions such as grasping, moving, precise alignment, and pressing. This repetitive physical labor easily leads to operator fatigue, making it difficult to guarantee positioning accuracy and consistency. When manually aligning the detection components, it is difficult to completely avoid angular deviations, uneven pressure, or positional shifts. Such fluctuations in positioning accuracy may result in poor sealing between the detection components and the cylinder port, affecting the accuracy and reliability of the detection results. Utility Model Content

[0005] The technical problem to be solved by this utility model is the dependence on manual labor and positioning accuracy, and an automatic material handling device for cylinder production is provided.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0023] This embodiment mainly elaborates on the structure of the material taking device, which is specifically as follows:

[0024] A material taking device for cylinder production, as Figures 1-4 shown, includes a base 1, an electric push rod 2, a fixture 3, a double-headed cylinder 4, a limiting rod 5, a clamping arm 6, a hopper 7, a detection device 18, and a blanking mechanism. A detection device 18 is arranged in front of the base 1, an electric push rod 2 is installed at the rear end of the base 1, a hopper 7 is connected to the upper end of the front end of the base 1, the front end of the piston rod of the electric push rod 2 is connected to the fixture 3, the base 1 bears the overall device, the electric push rod 2 drives the fixture 3 to move back and forth, and the linear advancement of the electric push rod 2 ensures that the cylinder to be inspected is coaxially aligned with the detection device 18. A double-headed cylinder 4 is installed in the fixture 3, limiting rods 5 are connected to both the left and right sides of the front end of the fixture 3, the piston rods at both the left and right ends of the double-headed cylinder 4 are connected to the clamping arms 6, and the clamping arms 6 are slidably connected to the limiting rods 5. The double-headed cylinder 4 is built into the fixture 3, and by contracting the piston rod, the clamping arms 6 are pulled to slide along the limiting rods 5 to achieve the clamping and release of the cylinder. The double-headed cylinder 4 synchronously controls the clamping force to avoid damage to the workpiece. A blanking mechanism for controlling the single-by-single dropping of the cylinders is arranged at the bottom of the hopper 7.

[0025] As Figure 2 and Figure 4 shown, the blanking mechanism includes a motor 8, a gear 9, a pulley group 10, a rotating rod 11, a resisting plate 12, a supporting component, and a blanking component. A motor 8 is installed on the front side of the hopper 7, two meshing gears 9 are rotatably connected to the front side of the hopper 7, and one of the gears 9 is connected to the output shaft of the motor 8. Rotating rods 11 are automatically connected to both the left and right sides of the bottom of the hopper 7. The motor 8 drives the gear group 9, and the torque is transmitted to the rotating rod 11 through the pulley group 10. A resisting plate 12 is connected to the rotating rod 11. The resisting plate 12 is in the shape of a "匚", and the length of the middle vertical rod is similar to the diameter of the cylinder, and the length of the top rod is shorter than that of the bottom rod. A pulley group 10 is arranged between the front end of the rotating rod 11 and the gear 9. The structure of the resisting plate 12 enables the cylinders to be separated one by one, preventing material jamming. A supporting component for supporting the dropped cylinders is arranged at the front end of the base 1, and the supporting component is located at the bottom of the hopper 7.

[0026] As Figure 2 and Figure 4As shown, the support assembly includes a support base 13 and a spring 14. The support base 13 is slidably connected to the base 1, and the spring 14 is sleeved on the support base 13. The top of the spring 14 is connected to the support base 13, and the bottom of the spring 14 is connected to the base 1. When the cylinder falls and impacts the support base 13, the spring 14 is compressed and absorbs kinetic energy. After rebounding, the arc plate at the top of the support base 13 stably supports the cylinder. The arc plate at the top of the support base 13 supports the cylinder.

[0027] like Figure 2 As shown, it also includes a feeding rack 15 and a baffle 19. The baffle 19 is connected to the left side of the base 1, and the feeding rack 15 is connected to the middle of the base 1. The feeding rack 15 is provided with an inclined surface facing the baffle 19, and the top of the inclined surface is flush with the top right of the electric push rod 2. The qualified cylinder falls to the inclined surface of the feeding rack 15 and slides along the inclined surface to the platform of the base 1. The baffle 19 limits and gathers the finished products, which is convenient for batch collection.

[0028] like Figure 3 As shown, it also includes a gasket 16. The gasket 16 is connected to one side of the two limit rods 5 adjacent to each other. The gasket 16 is deformed by pressure when clamping the cylinder, increasing the friction contact surface.

[0029] like Figure 1 As shown, it also includes a cover 17, which is snapped onto the top of the hopper 7.

[0030] The worker opens cover 17, places the cylinder to be inspected into hopper 7, closes cover 17, and starts the inspection process. Motor 8 drives gear 9 to rotate, and gear 9 drives rotating rods 11 on both sides to rotate via pulley set 10. The abutments 12 on both sides rotate towards the center along with the rotating rods 11. Since the length of abutment 12 is equal to the diameter of one cylinder, the abutment 12's push rod restricts the second cylinder from falling, while the bottom cylinder falls onto support base 13. The weight presses down on support base 13, and spring 14 is compressed and buffered before rebounding, pushing support base 13 back to its initial support position. Then, motor 8 drives gear 9 to rotate in the opposite direction, driving the abutment 12 to rotate via the two rotating rods 11. After the bottom cylinder falls, it is blocked by the bottom rod of abutment 12. The upward-curved arc plate at the top of support base 13 provides stable support for the cylinder. Then, electric push rod 2 drives clamp 3 to push towards the cylinder. Clamp 3 contacts the rear end of the cylinder, pushing the cylinder to move while simultaneously... After the first cylinder 4 pulls the clamping arm 6 to slide towards the center and clamps the cylinder, the electric push rod 2 pushes the clamp 3 forward. The limit rod 5 stabilizes the sliding of the clamping arm 6, thereby clamping the cylinder. The front end of the cylinder is inserted into the testing device 18. When the pad 16 on the inner side of the clamping arm 6 is squeezed with the cylinder, it undergoes elastic deformation, optimizing the clamping effect. The testing device 18 automatically tests the cylinder and directly outputs the test results. After the test is completed, the electric push rod 2 is controlled to retract according to the test results. If the test is qualified, the electric push rod 2 pulls the clamp 3 to retract, and releases the cylinder after it is fully retracted. The double-headed cylinder 4 pushes the two clamping arms 6 to slide outward. The clamping arms 6 release the cylinder, and the cylinder falls on the unloading rack 15. It falls along the slope of the unloading rack 15 onto the base 1 and is blocked by the baffle 19. It is then collected by the staff. If the test result is unqualified, the testing device 18 will sound an alarm, and the staff will manually remove the cylinder and collect it separately.
