Description

Technical Field

[0001] The utility model belongs to the technical field of linear stroke cylinders, and in particular relates to a cylinder valve installation structure and a linear stroke cylinder. Background Art

[0002] A straight-stroke cylinder is a cylindrical metal part that guides a piston to perform linear reciprocating motion in a cylinder. The basic principle is that air converts heat energy into mechanical energy by expanding in the engine cylinder, and the gas is compressed by the piston in the compressor cylinder to increase pressure. A straight-stroke cylinder is usually equipped with a valve position switch to accurately monitor and control the cylinder's movement position. Existing straight-stroke cylinders usually have a valve position switch installed at the bottom of the cylinder body, which may be limited by the installation space of the bottom valve bracket and the difficulty of installing the valve bracket or even the column. Since it is installed at the bottom of the cylinder body, the operating space is limited, resulting in the valve position switch being not securely fixed, and it may become loose after long-term operation on site.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] The utility model provides Figure 1-2 A cylinder valve installation structure shown includes:

[0017] A bottom plate 1, threaded rods 2 are rotatably connected on both sides of the top of the bottom plate 1, and a top plate 3 is threadedly connected between the two groups of threaded rods 2, two groups of guide rods 7 are provided on the top surface of the bottom plate 1, and the tops of the two groups of guide rods 7 slide through the top plate 3, mounting frames 4 are provided on both sides of the top of the top plate 3, a valve 5 is provided on the surface of one group of the mounting frames 4, and a valve position switch 6 is provided on the surface of the valve 5.

[0018] A switch fixing frame 9 is provided on the surface of the valve 5 , and the valve position switch 6 is provided on the surface of the switch fixing frame 9 .

[0019] The top of the threaded rod 2 is threadedly connected with a nut 8 , and the bottom of the base plate 1 is provided with a plurality of columns 10 . The columns 10 are provided in four groups and are respectively arranged at the four corners of the bottom of the base plate 1 , so that the base plate 1 is supported by the columns 10 .

[0020] A linear-stroke cylinder comprises the above-mentioned cylinder valve mounting structure.

[0021] It also includes a linear cylinder 11, which is arranged between a plurality of columns 10. The output shaft at the top of the linear cylinder 11 movably passes through the bottom plate 1 and the top plate 3 and is connected to the feedback rod 12. When the output shaft of the linear cylinder 11 extends or retracts, it will drive the feedback rod 12 to move together.

[0022] A circular contact 13 is sleeved on the surface of the feedback rod 12, and the surface of the circular contact 13 is in contact with the valve position switch 6. The feedback rod 12 drives the circular contact 13 on the top surface to contact or disconnect with the valve position switch 6 during movement.

[0023] The cylinder valve mounting structure and the linear cylinder are achieved by mounting and fixing the mounting frame 4 to the surface of the top plate 3, and installing the valve 5. The valve position switch 6 is fixed to the surface of the valve 5 by a switch fixing frame 9, so that the valve position switch 6 can be installed to the top space of the linear cylinder 11. When the linear cylinder 11 is running, when the output shaft of the linear cylinder 11 is extended or retracted, the feedback rod 12 will be driven to move together. The feedback rod 12 will drive the circular contact 13 on the top surface to contact or disconnect with the valve position switch 6 during the movement. When the circular contact 13 contacts the valve position switch 6, an electrical signal will be triggered, indicating that the linear cylinder 11 has reached the predetermined position, so that the electrical signal can be captured and processed by the control system, and the position and movement state of the linear cylinder 11 can be monitored in real time, ensuring that the linear cylinder 11 moves according to the predetermined trajectory and timing, thereby realizing precise control of the stroke of the linear cylinder 11.

[0024] By installing the valve position switch 6 to the top space of the linear cylinder 11, there is enough installation space for installing the valve position switch 6, avoiding the situation where the installation space is narrow due to installation at the bottom of the linear cylinder 11. The valve position switch 6 is installed on the top of the linear cylinder 11, which makes it easy to adjust and install during installation and convenient to operate.
