Description

Technical Field

[0001] This utility model relates to the field of cylinder technology, and in particular to an internal cavity high thrust cylinder. Background Technology

[0002] In the field of industrial automation production, cylinders, as common power actuators, are widely used in operations such as pushing, clamping, and assembly. Their operational stability, operational accuracy, and ease of maintenance directly affect the efficiency of the entire production line and the quality of products.

[0003] Currently, some cylinders on the market have unreasonable guide structure designs, which can easily lead to uneven force on one side when pushing the load, causing the piston to jam. This not only shortens the cylinder's service life but also affects the continuity and stability of the operation.

[0004] To address the aforementioned problems, this utility model proposes an internal cavity type high thrust cylinder. Utility Model Content

[0005] This invention provides an internal cavity high-thrust cylinder, which solves the problem that some cylinders in the prior art have unreasonable guide structure design, which easily leads to uneven force on one side when pushing the load, causing piston movement to jam, which not only shortens the service life of the cylinder, but also affects the continuity and stability of operation.

[0006] This utility model provides the following technical solution: An internal cavity type high thrust cylinder, comprising: A vertically oriented base plate has round shafts fixed to each of the four corners of one side of the base plate using hexagon head screws. An internal cavity high-thrust cylinder body is fixed to the center of one side of the base plate using hexagon head screws. A cylinder plate is fixed to the output end of the internal cavity high-thrust cylinder body using baffle bolts. Hexagonal shafts are fixed to the upper left and lower right corners of the cylinder plate using hexagon head screws. A fixing block is fixed to the other side of the base plate, and a solenoid valve is fixed to the fixing block using Phillips head screws.

[0007] In one possible design, the round shaft and the internal cavity high-thrust cylinder body are mounted on the same side of the base plate.

[0008] In one possible design, the solenoid valve is equipped with three quick-connect fittings for use, and a silencer is also installed on the solenoid valve.

[0009] In one possible design, the top of the internal cavity high-thrust cylinder body is provided with two matching air source connectors. The air source connectors are connected to pneumatic hoses, and the other end of the pneumatic hoses is connected to a corresponding quick connector on the solenoid valve. The quick connector on the other side of the solenoid valve is connected to the air source output end through the pneumatic hose.

[0010] In one possible design, the two leads at the bottom of the solenoid valve are respectively welded with IHS wires representing the positive and negative poles.

[0011] In one possible design, the lead wire at the bottom of the solenoid valve and the solder joint of the IHS wire are both protected by heat shrink tubing.

[0012] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0013] The working principle and usage process of this technical solution are as follows: When in use, after receiving the start signal, the device enters the power output process to realize the directional movement of the cylinder plate. The external air source enters the solenoid valve through the pneumatic hose and the quick connector on one side of the solenoid valve. At this time, the solenoid valve switches the air path according to the control signal, directing the compressed air to the corresponding quick connector. The compressed air is transmitted to the corresponding air source connector on the top of the cylinder body through the pneumatic hose connected to the quick connector, and enters the inner cavity of the cylinder body, pushing the internal piston to move. The piston drives the cylinder plate at the output end to move in a preset direction. At the same time, the hexagonal shaft on the cylinder plate moves together, which can cooperate with the external actuator to complete operations such as pushing and clamping. During this process, the round shaft plays a guiding role to ensure the stability of the cylinder plate's movement trajectory and avoid deviation. After the operation is completed, the device enters the reset or stop state, restoring the initial position or cutting off the power. If a reset is required, the control signal changes the air circuit state of the solenoid valve. The external air source enters the cylinder cavity through the air source connector on the other side of the top of the cylinder body via the channel switched by the solenoid valve, another set of quick connectors and pneumatic hoses, pushing the piston to move in the opposite direction, driving the cylinder plate and hexagonal shaft back to the initial position. The original gas in the cylinder body enters the solenoid valve through the corresponding pneumatic hoses and quick connectors, and is finally discharged through the muffler to reduce exhaust noise. If operation needs to be stopped, simply cut off the external air supply and the control signal of the solenoid valve. The solenoid valve closes the air circuit channel, the cylinder body piston maintains the current position, and the device stops power output.

[0014] This utility model has the following beneficial effects: This invention employs multiple robust connection methods. The core components are all connected using compatible hexagonal head screws, baffle bolts, and Phillips head screws. These screw connections offer high fastening strength and, when used with corresponding washers, can withstand the impact and vibration during cylinder operation, preventing component loosening. Simultaneously, the cylindrical shaft is coplanarly mounted with the cylinder body, ensuring uniform force distribution during cylinder plate movement, reducing the risk of unilateral offset, further enhancing structural stability, ensuring the device is less prone to failure during long-term operation, and extending its service life.

[0015] In this invention, the solenoid valve has a rapid air circuit switching response and can adjust the flow direction of compressed air in real time according to the control signal, so as to realize the rapid start-up, shutdown and reversal of the cylinder, shorten the operation cycle and improve work efficiency. The solenoid valve lead wire and the IHS wire are wrapped with heat shrink tubing, which can effectively isolate external impurities such as dust and moisture, prevent oxidation or short circuit of the welding point, ensure the stability of the circuit connection, reduce the probability of device downtime due to circuit problems, and improve the overall operational reliability.

[0016] The use of quick connectors in this invention simplifies the connection process between pneumatic hoses and solenoid valves and cylinder bodies, allowing for quick plugging and unplugging without the need for specialized tools. This facilitates air circuit debugging during initial installation and pipeline replacement during subsequent maintenance. The selection of universal fasteners such as hex socket head cap screws and Phillips head screws reduces the difficulty of adapting installation tools, allowing operators to complete basic assembly without special training, thus improving installation efficiency.

[0017] In this utility model, all components of the device are modularly installed. Core components such as solenoid valves and cylinder bodies are independently located and clearly marked. When a fault occurs, the problematic component can be quickly located and disassembled for repair without disassembling the overall structure. The matching installation of the muffler reduces operating noise while ensuring exhaust function, reduces interference with the working environment, improves operating comfort, and further enhances the practicality of the device.

[0018] In this invention, the round shaft plays a precise guiding role in the movement of the cylinder plate, avoiding deviation during the movement process and ensuring that the cylinder plate and hexagonal shaft can move stably according to the preset trajectory, thereby improving the accuracy of the working position. It is suitable for industrial scenarios with high requirements for thrust and precision, such as precision assembly and automated production lines. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted. Example

[0024] Please refer to Figure 1-4 An internal cavity type high thrust cylinder, used in the field of cylinders, includes: In the vertical position of the base plate 1, four round shafts 2 are fixed at the four corners of one side of the base plate 1 using hex socket head cap screws to ensure a tight connection between the round shafts 2 and the base plate 1 without any looseness. At the center of the same side of the base plate 1, the inner cavity high thrust cylinder body 8 is also fixed using hex socket head cap screws to make the round shafts 2 and the inner cavity high thrust cylinder body 8 on the same plane, ensuring that the force is evenly distributed when the cylinder plate 3 moves.

[0025] At the output end of the internal cavity high thrust cylinder body 8, the cylinder plate 3 is fixed by the baffle bolt. The position of the cylinder plate 3 is adjusted to ensure that it is tightly fitted with the connecting surface of the output end of the internal cavity high thrust cylinder body 8. At the upper left and lower right corners of the cylinder plate 3, two hexagonal shafts 9 are fixed by internal hexagonal head screws. During the fixing process, it is necessary to ensure that the axis of the hexagonal shafts 9 is consistent with the preset movement direction so that they can cooperate with the external actuator to complete the operation.

[0026] On the other side of the base plate 1, a fixing block 4 is welded and fixed to ensure that the connection strength between the fixing block 4 and the base plate 1 meets the installation requirements of the solenoid valve 6. The solenoid valve 6 is fixed to the fixing block 4 with cross-head screws. During installation, the angle of the solenoid valve 6 needs to be adjusted so that its interface faces the direction that facilitates subsequent pipeline connection. Three matching quick connectors 5 are installed on the solenoid valve 6, ensuring that each quick connector 5 is installed in place without the risk of air leakage. At the same time, a silencer 7 is installed at the preset exhaust interface of the solenoid valve 6 to ensure good sealing between the silencer 7 and the interface.

[0027] Install two matching air source connectors 10 on the top of the internal cavity high thrust cylinder body 8. Then take two pneumatic hoses 11, connect one end of one pneumatic hose 11 to one air source connector 10 on the top of the internal cavity high thrust cylinder body 8, and connect the other end to one quick connector 5 on the solenoid valve 6. Connect one end of the other pneumatic hose 11 to another air source connector 10 on the top of the internal cavity high thrust cylinder body 8, and connect the other end to the second quick connector 5 on the solenoid valve 6. Take a third pneumatic hose 11, connect one end of it to the remaining quick connector 5 on the solenoid valve 6, and reserve an interface for connecting the other end to the external air source output.

[0028] On the two leads at the bottom of the solenoid valve 6, IHS wires 13 representing the positive and negative poles are welded respectively. After welding, two sections of heat shrink tubing 12 are taken and put on the welding joints of the solenoid valve 6 leads and IHS wires 13 respectively. By heating, the heat shrink tubing 12 shrinks and tightly wraps the welding joint to protect the welding point.

[0029] During specific operation, connect the end of the reserved third pneumatic hose 11 to the output end of the external air source, and connect the other end of the IHS wire 13 to the external control system to complete the docking of the device with the external equipment. After the external control system sends a start signal to the solenoid valve 6, the external air source enters the solenoid valve 6 through the third pneumatic hose 11 and the corresponding quick connector 5 on the solenoid valve 6. The solenoid valve 6 switches the internal air passage according to the received control signal and guides the compressed air to one of the quick connectors 5 that are connected to the inner cavity high thrust cylinder body 8. Compressed air is transmitted through the pneumatic hose 11 connected to the quick connector 5 to the air source connector 10 corresponding to the top of the internal cavity high thrust cylinder body 8, and then enters the internal cavity of the internal cavity high thrust cylinder body 8, pushing the piston in the internal cavity to move in a preset direction. During the piston movement, the cylinder plate 3 at the output end of the internal cavity high thrust cylinder body 8 moves synchronously. The hexagonal shaft 9 on the cylinder plate 3 moves together with the cylinder plate 3. The hexagonal shaft 9 cooperates with the external actuator to complete preset operations such as pushing and clamping. During this process, the round shafts 2 at the four corners of one side of the base plate 1 guide the movement of the cylinder plate 3, restrict the movement trajectory of the cylinder plate 3, and prevent it from deviating. After the operation is completed, the external control system sends a reset signal to the solenoid valve 6. After receiving the signal, the solenoid valve 6 changes the internal air circuit state. The external air source enters the inner cavity from the air source connector 10 on the other side of the top of the inner cavity high thrust cylinder body 8 through the channel switched by the solenoid valve 6, through another quick connector 5 and pneumatic hose 11 connected to the inner cavity high thrust cylinder body 8, and pushes the piston to move in the opposite direction. The reverse movement of the piston drives the cylinder plate 3 and hexagonal shaft 9 back to the initial position. The original gas in the inner cavity high thrust cylinder body 8 enters the solenoid valve 6 through the corresponding side air source connector 10, pneumatic hose 11 and quick connector 5, and is finally discharged through the muffler 7 on the solenoid valve 6. During the discharge process, the muffler 7 weakens the noise generated by the gas flow. If it is necessary to stop the operation of the device, the external control system cuts off the control signal sent to the solenoid valve 6 and closes the valve at the output end of the external air source to cut off the air supply. After losing the control signal, the solenoid valve 6 closes the internal air passage. The piston in the internal cavity high thrust cylinder body 8 remains in the current position, the device stops power output, and completes one work cycle. When the device experiences a gas leak, check the connection points of each quick connector 5 and pneumatic hose 11 in sequence. If loose, simply tighten the quick connector 5 manually. If the quick connector 5 or pneumatic hose 11 is damaged, simply remove the damaged part and replace it with a new quick connector 5 or pneumatic hose 11. No other structure needs to be disassembled. When the device experiences a circuit fault, check the welded joint wrapped with heat shrink tubing 12. If the heat shrink tubing 12 is damaged, replace it with a new one. If the weld is oxidized or broken, peel off the original heat shrink tubing 12 and re-weld it. After welding, put the heat shrink tubing 12 back on for protection. When it is necessary to repair the internal high-thrust cylinder body 8 or the solenoid valve 6, unscrew the hexagonal head screws that fix the internal high-thrust cylinder body 8 or the Phillips head screws that fix the solenoid valve 6 to remove the corresponding parts. After repair, re-fix them according to the original assembly method.

[0030] However, as is well known to those skilled in the art, the working principle and wiring method of the internal high-thrust cylinder body 8 and the solenoid valve 6 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0031] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
