Description

Technical Field

[0001] This utility model relates to the field of cylinder technology, specifically a protective guide rod cylinder. Background Technology

[0002] A pneumatic slide cylinder is a common pneumatic actuator, referring to a cylindrical metal component that guides a piston in linear reciprocating motion. It is mainly used for linear motion control in industrial automation systems. It typically consists of a cylinder barrel, piston, piston rod, seals, guide components, and an air source interface. This cylinder, also known as a pneumatic slide, provides precision guidance, support, and drive functions. It is a pneumatic component mechanism consisting of a cylinder and a precision wide linear guide rail. By directly using the linear guide rail worktable as the slide, it achieves unprecedented precision and rigidity, making it easier to use.

[0003] A slide cylinder disclosed in Chinese Utility Model Patent Application Publication No. CN220668004U, although it can achieve precise control of the movement of the slide body by means of a fixedly set sensor bracket and sensor, thereby improving the accuracy of the slide cylinder during use, the existing cylinder may experience problems such as loosening and detachment of the inlet and outlet pipes after long-term use, and cylinder wear caused by collisions, leading to cylinder failure and reduced service life. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a protective guide rod cylinder, which solves the problems that existing cylinders may experience loosening or detachment of the inlet and outlet pipes after prolonged use, as well as cylinder wear caused by collisions, leading to cylinder malfunctions and inoperability.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a protective guide rod cylinder, comprising a cylinder, an inlet / outlet hole on one side of the cylinder, a clamping assembly inserted inside the inlet / outlet hole, a main piston slidably connected inside the cylinder, a piston rod inserted into one side of the main piston, a fixing plate sleeved on one end of the piston rod, an upper limit rod and a lower limit rod inserted into one side of the fixing plate, a protective pad snapped onto one side of the fixing plate, a movable plate slidably connected to the surface of the piston rod, a buffer assembly inserted into one side of the movable plate, and sliding grooves on both sides of the cylinder.

[0006] Optionally, the clamping assembly includes a clamping pad, a clamping telescopic rod, a clamping spring, a mating pad, and a clamping half-ring. The clamping telescopic rod is inserted into one side of the clamping pad, the surface of the clamping telescopic rod is provided with a clamping spring, one end of the clamping telescopic rod is sleeved with a mating pad, and one side of the mating pad is sleeved with a clamping half-ring.

[0007] Optionally, the clamping pad is made of rubber, and the mating pad is made of rubber.

[0008] Optionally, a contact pad is provided on one side of the clamping semi-ring, and the contact pad is made of rubber.

[0009] Optionally, the buffer assembly includes a fixed pad, a buffer telescopic rod, a buffer spring, and a buffer pad. The buffer telescopic rod is inserted into one side of the fixed pad, the surface of the buffer telescopic rod is provided with a buffer spring, and a buffer pad is sleeved on one end of the buffer telescopic rod.

[0010] Optionally, the fixing pad is made of rubber, and the buffer pad is made of rubber.

[0011] Optionally, the protective pad is located between the fixed plate and the movable plate, the protective pad is made of rubber, and the cylinder has an upper limit cavity and a lower limit cavity inside.

[0012] Optionally, the piston rod is located between the upper limit rod and the lower limit rod, the piston rod is made of hard alloy, and the cylinder has a piston chamber inside, which communicates with the inlet and outlet holes.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model has a reasonable structure. Workers insert two intake pipes into the upper intake / exhaust holes on one side of the cylinder, and two exhaust pipes into the lower intake / exhaust holes on the other side. The clamping telescopic rod, along with the clamping spring, compresses the intake and exhaust pipes. Once the intake and exhaust pipes are in place with the cylinder, the clamping spring causes the clamping telescopic rod, along with the clamping semi-ring, to securely hold the intake and exhaust pipes. This achieves convenient and quick secondary fixation and protection of the intake and exhaust pipes. The operation is simple and flexible, improving the installation efficiency of the intake and exhaust pipes. This reduces the risk of the intake and exhaust pipes detaching during prolonged operation, which could cause equipment downtime and require maintenance, thus affecting work progress. The intake pipes supply air to the piston chamber of the cylinder, causing the main piston and piston rod to move along with the fixed plate. The movement of the piston rod then moves the upper and lower limit chambers. The piston rod and lower limit rod also move out to limit the movement of the piston rod. When the fixed plate moves back, the air in the piston chamber is discharged through the air outlet pipe on one side of the cylinder, and air is supplied into the piston chamber through the other air inlet pipe, causing the main piston and piston rod to move back with the fixed plate. This causes the upper limit rod and lower limit rod to move into the upper limit chamber and lower limit chamber, respectively. When the cylinder touches the buffer pad, the buffer telescopic rod, along with the buffer spring, is compressed into the moving plate. The protective pad protects the moving plate. When the moving plate moves away from the cylinder, the buffer spring, along with the buffer telescopic rod and buffer pad, moves out of the moving plate, thus achieving buffer protection for the cylinder. This reduces the need for frequent cylinder maintenance, thereby reducing the potential damage to the cylinder during prolonged and rapid use and shortening the equipment's service life. External equipment can be connected through the sliding grooves on both sides of the cylinder to work in conjunction with it. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figures 1-6 The protective guide rod cylinder shown includes a cylinder 1. An inlet / outlet hole 2 is provided on one side of the cylinder 1. A clamping assembly 3 is inserted into the inlet / outlet hole 2. A main piston 4 is slidably connected inside the cylinder 1. A piston rod 5 is inserted into one side of the main piston 4. A fixing plate 6 is sleeved on one end of the piston rod 5. An upper limit rod 7 and a lower limit rod 8 are inserted into one side of the fixing plate 6. A protective pad 9 is snapped into one side of the fixing plate 6. A moving plate 10 is slidably connected to the surface of the piston rod 5. A buffer assembly 11 is inserted into one side of the moving plate 10. Slide grooves 12 are provided on both sides of the cylinder 1.

[0024] As a preferred embodiment of this example, Figures 2 to 6As shown, an inlet / outlet hole 2 is provided on one side of cylinder 1. A clamping assembly 3 is inserted into the inlet / outlet hole 2. The clamping assembly 3 is symmetrical and includes a clamping pad 301, a clamping telescopic rod 302, a clamping spring 303, a mating pad 304, and a clamping semi-ring 305. The clamping pad 301 is made of rubber. The clamping telescopic rod 302 is inserted into one side of the clamping pad 301. The surface of the clamping telescopic rod 302 is provided with a clamping spring 303. A mating pad 304 is sleeved on one end of the clamping telescopic rod 302. The mating pad 304 is made of rubber. A clamping semi-ring 305 is sleeved on one side of the mating pad 304. A contact pad made of rubber is provided on one side of the clamping semi-ring 305. A main piston 4 is slidably connected inside cylinder 1. A movable spring 305 is inserted into one side of the main piston 4. The piston rod 5 is located between the upper limit rod 7 and the lower limit rod 8. The piston rod 5 is made of hard alloy. The cylinder 1 has a piston chamber inside, which is connected to the inlet / outlet hole 2. A fixing plate 6 is sleeved on one end of the piston rod 5. The upper limit rod 7 and the lower limit rod 8 are inserted into one side of the fixing plate 6. The cylinder 1 has an upper limit cavity and a lower limit cavity inside. A protective pad 9 is snapped onto one side of the fixing plate 6. The protective pad 9 is located between the fixing plate 6 and the moving plate 10. The protective pad 9 is made of rubber. The moving plate 10 is slidably connected to the surface of the piston rod 5. A buffer assembly 11 is inserted into one side of the moving plate 10. There are four buffer assemblies 11, which are located at the four corners of the moving plate 10. The buffer assembly 11 includes a fixing pad 101, a buffer telescopic rod 102, and a buffer... The cylinder 1 has spring 103 and buffer pad 104. The fixing pad 101 is made of rubber. A buffer telescopic rod 102 is inserted into one side of the fixing pad 101. A buffer spring 103 is provided on the surface of the buffer telescopic rod 102. A buffer pad 104 is sleeved on one end of the buffer telescopic rod 102. The buffer pad 104 is made of rubber. Slide grooves 12 are opened on both sides of the cylinder 1. During use, the operator inserts two air inlet pipes into the inlet / outlet holes 2 on the upper side of the cylinder 1 and two air outlet pipes into the inlet / outlet holes 2 on the lower side of the cylinder 1. The clamping telescopic rod 302 compresses the clamping spring 303. After the air inlet pipes and air outlet pipes are inserted into the cylinder 1, the clamping spring 303 causes the clamping telescopic rod 302 to compress the air inlet pipes and air outlet pipes with the clamping semi-ring 305. The fixed clamping mechanism provides convenient and quick secondary fixation and protection for the inlet and outlet pipes. It allows for simple and flexible operation by staff, improving installation efficiency and reducing the risk of the inlet and outlet pipes detaching during prolonged operation, which could cause equipment downtime and require maintenance, thus impacting work progress. Air is supplied to the piston chamber of cylinder 1 through the inlet pipe, causing the main piston 4 and piston rod 5 to move along with the fixing plate 6. The movement of piston rod 5 also moves the upper and lower limit rods 7 and 8 from the upper and lower limit chambers, limiting the movement of piston rod 5. When the fixing plate 6 needs to move back, the air in the piston chamber is discharged through the outlet pipe on one side of cylinder 1.Air is supplied to the piston chamber through another intake pipe, causing the main piston 4 and piston rod 5 to move back along with the fixed plate 6. This also moves the upper limit rod 7 and lower limit rod 8 into the upper and lower limit chambers, respectively. When the cylinder 1 touches the buffer pad 104, the buffer telescopic rod 102, along with the buffer spring 103, is compressed into the moving plate 10. The protective pad 9 protects the moving plate 10. When the moving plate 10 moves away from the cylinder 1, the buffer spring 103, along with the buffer telescopic rod 102 and the buffer pad 104, moves out of the moving plate 10. This achieves buffer protection for the cylinder 1, reducing the need for frequent maintenance and minimizing potential damage to the cylinder 1 during prolonged high-speed use. This shortens the equipment's lifespan. External equipment can be connected via the sliding grooves 12 on both sides of the cylinder 1 for use in conjunction with it.

[0025] The working principle of this practical application is as follows:

[0026] During use, the operator inserts two intake pipes into the upper intake / exhaust holes 2 on one side of cylinder 1, and two exhaust pipes into the lower intake / exhaust holes 2 on one side of cylinder 1. The clamping telescopic rod 302 compresses the clamping spring 303. Once the intake and exhaust pipes are in place with cylinder 1, the clamping spring 303 causes the clamping telescopic rod 302, along with the clamping half-ring 305, to securely clamp the intake and exhaust pipes. Air is supplied to the piston chamber of cylinder 1 through the intake pipes, causing the main piston 4 and piston rod 5 to move along with the fixing plate 6. The movement of the piston rod 5 also moves the upper limit rod 7 and lower limit rod 8 from the upper and lower limit chambers, respectively. This movement of the piston... The stopper 5 is used for limiting. When the fixed plate 6 needs to move back, the air in the piston chamber is discharged through the air outlet pipe on one side of the cylinder 1, and air is supplied into the piston chamber through the other air inlet pipe, so that the main piston 4 and piston rod 5 move back with the fixed plate 6. When the cylinder 1 touches the buffer pad 104, the buffer telescopic rod 102 and the buffer spring 103 are compressed into the moving plate 10. The moving plate 10 is protected by the protective pad 9. When the moving plate 10 moves away from the cylinder 1, the buffer spring 103 moves the buffer telescopic rod 102 and the buffer pad 104 out of the moving plate 10. External equipment can be connected through the sliding grooves 12 on both sides of the cylinder 1 to cooperate with the cylinder 1.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
