Description

Technical Field

[0001] This utility model belongs to the technical field of double-section cylinders, and particularly relates to a double-section cylinder for machine tool pneumatic components. Background Technology

[0002] Double-section cylinders, also known as double-stroke cylinders or double-force cylinders, are a special type of actuator in machine tool pneumatic systems. Through a nested double-cylinder design, they achieve double the output force or segmented stroke control within a compact space. Double-section cylinders solve the core requirements of small space, high output, and variable stroke in machine tool pneumatic systems through structural innovation, and are particularly suitable for scenarios such as automated fixtures and tool changing mechanisms.

[0003] The dual-section cylinders currently available for machine tools have the following problems when used:

[0004] 1. Traditional machine tool pneumatic components, such as double-section cylinders, typically require fasteners to directly connect the cylinder body to the mounting surface. When disassembling the cylinder body, one hand must hold the cylinder assembly while the other hand uses a tool to remove it. This operation is time-consuming and laborious. Furthermore, if the cylinder is not held securely during disassembly, it may fall. Therefore, disassembly and assembly are inconvenient.

[0005] 2. In most applications of double-section pneumatic cylinders for machine tools, the air pipe is usually installed directly outside the air inlet and outlet. If the air pipe becomes loose, the cylinder will lack power, resulting in a weak sealing effect during application. Utility Model Content

[0006] The purpose of this utility model is to provide a double-section cylinder for machine tool pneumatic components to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A double-section pneumatic cylinder for machine tools includes a cylinder body and a piston rod.

A threaded hole 23 is provided on the outside of the cylinder body 1, and a through hole 24 is provided on the outer side of the base 7. The clamping screw 9 passes through the through hole 24. By installing the base 7 at the bottom of the cylinder body 1, and... A clamping screw 9 is embedded inside the limiting frame 8, and a limiting rod 12 is embedded inside the Y-shaped limiting plate 10. The base 7 is installed on the mounting surface using fasteners. Subsequently, the limiting rod 12 on the outside of the cylinder body 1 is embedded inside the Y-shaped limiting plate 10, and then the fastening screw is tightened to fix it. When disassembling the cylinder body 1, the fastening screw is tightened in the opposite direction to remove the limiting rod 12 from inside the Y-shaped limiting plate 10. This facilitates quick assembly and disassembly of the cylinder body 1. The clamping screw 9 is threadedly connected to the threaded hole 23. The outer side of the base 7 is provided with a mounting plate 21, and the mounting plate 21 has a mounting hole 22 inside. Because of the mounting plate 21 and the mounting hole 22, it is convenient to fix the base 7 to the mounting surface with fasteners.

[0031] A rubber sleeve 16 is provided on the outside of the air inlet 4 and the air outlet 5. A sealing ring 15 is provided on the side of the rubber sleeve 16. A fixing plate 17 is provided on the outside of the cylinder body 1. A pressing screw 18 is provided inside the fixing plate 17. A rubber plate 20 is provided on the side of the pressing screw 18. The rubber plates 20 are symmetrically distributed. By providing a threaded ring 14 and a rubber sleeve 16 on the outside of the threaded groove 13, and installing the pressing screw 18 inside the fixing plate 17, and installing the rubber plate 20 on the side of the pressing screw 18, the sealing ring 15 is turned to install the rubber sleeve 16 on the outside of the air inlet 4 and the air outlet respectively. Then, the pipe is installed inside the rubber sleeve 16. Subsequently, the pressing screw 18 is turned from both sides to press the rubber plate 20 tightly on the outside of the rubber sleeve 16. In this way, the sealing of the pipe can be strengthened.

[0032] A connecting plate 11 is provided on the side of the cylinder body 1, and a limiting rod 12 is provided at the bottom of the connecting plate 11. The limiting rods 12 are distributed in a distributed manner. Due to the presence of the connecting plate 11, it is convenient to connect the cylinder body 1 and the limiting rods 12.

[0033] The piston rod 2 has a baffle 3 on its side, and a magnetic switch mounting slot 6 is opened on the outside of the cylinder body 1. The magnetic switch mounting slot 6 makes it convenient to install the magnetic switch on the outside of the cylinder body 1.

[0034] A threaded groove 13 is provided on the side of the cylinder body 1, and a threaded ring 14 is provided at the bottom of the sealing ring 15. The threaded ring 14 is threadedly connected to the threaded groove 13. Because of the threaded groove 13 and the threaded ring 14, it is convenient to install and fix the rubber sleeve 16 to the outside of the air outlet 5 and the air inlet 4.

[0035] The extrusion screw 18 is provided with a turntable seat 19 on its side, and a rubber plate 20 is provided on the outer side of the turntable seat 19.

[0036] The working principle of the double-section cylinder of this machine tool pneumatic component is as follows: When using the cylinder body 1, to facilitate the installation of the double-section cylinder, a base 7 is installed at the bottom of the cylinder body 1, and a clamping screw 9 is embedded inside the limit frame 8. A limit rod 12 is embedded inside the Y-shaped limit plate 10. Before installing the cylinder body 1, fasteners are used to pass through the mounting holes 22 to install the mounting plate 21 on the mounting surface. The base 7 is then installed on the mounting surface. Subsequently, the limit rod 12 on the outside of the cylinder body 1 is embedded in the Y-shaped limit plate 10. Inside, tighten the fastening screw inside the limit bracket 8 to connect and fix the fastening screw to the threaded hole 23. This allows the cylinder body 1 to be installed on the base 7 without directly connecting and fixing the cylinder body 1 to the mounting surface. When the cylinder body 1 needs to be disassembled later, the operator simply reverses the tightening screw to remove it from inside the limit bracket 8, and then removes the limit rod 12 from inside the Y-shaped limit plate 10. This facilitates quick assembly and disassembly of the cylinder body 1, making the assembly and disassembly operation relatively simple. The workers first removed the pipes and installed them on the outside of the air inlet 4 and air outlet 5, respectively. To improve the sealing strength between the pipes and the cylinder body 1, a threaded ring 14 and a rubber sleeve 16 were installed on the outside of the threaded groove 13. A sealing ring 15 was installed on the outside of the sealing ring 15, and a compression screw 18 was installed inside the fixing plate 17. A rubber plate 20 was installed on the side of the compression screw 18. The rubber sleeve 16 was removed, and then the sealing ring 15 was turned clockwise to install the rubber sleeve 16 on the outside of the air inlet 4 and air outlet, respectively. First, the pipe is installed inside the rubber sleeve 16. Then, the extrusion screws 18 are turned from both sides to press the rubber plate 20 tightly against the outside of the rubber sleeve 16. This strengthens the sealing of the pipe, resulting in a strong sealing effect during application. Finally, when the cylinder body 1 needs to be inspected, the extrusion screws 18 are turned in the opposite direction to remove the rubber plate 20 from the outside of the rubber sleeve 16. Then, the air pipe can be removed from inside the rubber sleeve 16, and the cylinder body 1 can be removed from inside the base 7. This allows for the inspection and maintenance of the device body.
