[0053] Please see Figures 1-6 One embodiment of this utility model provides a piston cylinder with a control valve 2, comprising:

[0054] The cylinder body 1 has a cavity, in which a cylinder piston 13 is slidably connected, and the cavity is divided by the cylinder piston 13 to form an upper cavity 11 and a lower cavity 12.

[0055] Control valve 2 is used to control the air source to drive the cylinder piston 13 to reciprocate in the cavity along the direction of the upper cavity 11 and the lower cavity 12; wherein, the control valve 2 is installed on the cylinder body 1, or the control valve 2 is set close to the cylinder body 1 and connected to the cylinder body 1 through a pipe.

[0056] In this embodiment, by detaching the valve plate (i.e., control valve 2) from the valve island (upstream) and moving it to the vicinity of the cylinder body 1 (downstream) or installing it on the cylinder body 1, the cylinder action time is reduced, achieving the integrated effect of the cylinder and control valve 2 being set up as one unit. This avoids unnecessary losses during the process of the air source being delivered to the cylinder body 1, improves the air source utilization rate and the working efficiency of the cylinder, and saves delivery time, thus avoiding affecting the rhythm of industrial production.

[0057] By integrating the cylinder and control valve 2 into one unit or placing them close together, it is not only aesthetically pleasing but also avoids occupying too much space around the cylinder. This optimizes the overall structure and design layout, achieving a standardized and modular design effect. It also achieves a high degree of integration between the cylinder and control valve 2, reduces installation steps such as electrical piping, improves the cylinder's response speed and operating cycle, and simplifies the equipment's air circuit layout, reducing the investment and arrangement of air pipes 3 on the equipment. Through this solution, each cylinder can be independently equipped with a valve plate (i.e., control valve 2), which simplifies the PLC's control logic and saves equipment costs.

[0058] In one embodiment, the cylinder body 1 is further provided with a first cavity 111 and a second cavity 121 for air source flow, wherein the first cavity 111 is connected to the upper cavity 11 and the second cavity 121 is connected to the lower cavity 12.

[0059] In this embodiment, by optimizing the internal structure of the cylinder body 1, a first cavity 111 and a second cavity 121 are provided in the cylinder body 1 so that the control valve 2 can be connected to the upper cavity 11 and the lower cavity 12 through the first cavity 111 and the second cavity 121 respectively, ensuring that during operation, the control valve 2 can control the air source to enter the cylinder to drive the cylinder piston 13 to reciprocate along the direction of the upper cavity 11 and the direction of the lower cavity 12 in the cavity.

[0060] Please see Figures 1-4 In one embodiment, a cylinder piston rod 14 is also included. One end of the cylinder piston rod 14 is connected to the cylinder piston 13 to follow the movement of the cylinder piston 13 relative to the cylinder body 1, and the other end extends from the cavity to the outside of the cylinder body 1. The cylinder piston rod 14 is sealed to the cylinder body 1.

[0061] In this embodiment, the air source is directly supplied from the air pipe 3 to the inside of the cylinder body 1 through the control valve 2. The cylinder piston 13 inside the cylinder body 1 divides the cavity inside the cylinder body 1 into an upper cavity 11 and a lower cavity 12. Figure 4 As shown, when an electrical signal is sent to control valve 2, control valve 2 is switched, and the air source enters the lower chamber 12 through air pipe 3 and the second chamber 121, pushing the cylinder piston 13 and cylinder piston rod 14 to move towards the upper chamber 11, and the cylinder piston rod 14 extends; as Figure 3 As shown, when the electrical signal is sent to the control valve 2 again, the control valve 2 is switched in the reverse direction. The air source enters the upper cavity 11 through the air pipe 3 and the first cavity 111, and pushes the cylinder piston 13 and the cylinder piston rod 14 to move towards the lower cavity 12. The cylinder piston rod 14 retracts, and the extension and retraction actions of the cylinder piston rod 14 are completed in a cycle.

[0062] in, Figure 2 The dashed lines represent the cylinder piston 13 and cylinder piston rod 14 connected inside the cylinder body 1. This cylinder is a single-rod cylinder, also known as a thin-type cylinder, which is a cylindrical cylinder that guides the cylinder piston rod 14 in linear reciprocating motion within the cylinder body 1. Thin-type cylinders are widely used in the welding of body-in-white due to their compact structure, small footprint, and ability to be directly mounted on various fixtures without the need for accessories. In this embodiment, by integrating the cylinder body 1 and control valve 2 into a single unit or placing them close together, the air circuit layout of the cylinder equipment can be simplified, and the actual on-site operating cycle time can be improved.

[0063] Please see Figures 5-6 In one embodiment, a cylinder piston rod 14 is also included. The cylinder piston rod 14 is disposed in the cavity, and one end of the cylinder piston rod 14 is connected to the cylinder piston 13, and the other end is connected to the pressure arm 16 through a connecting rod hinge 15, so as to drive the pressure arm 16 to rotate around the preset rotation point 151 of the connecting rod hinge 15 with the movement of the cylinder piston 13.

[0064] In this embodiment, as Figure 6 As shown, the internal connecting rod hinge 15 generates force under the action of the cylinder piston rod 14, causing the pressure arm 16 to rotate around the preset rotation point 151 of the connecting rod hinge 15, thereby opening the clamping component on the pressure arm 16. In this embodiment, the cylinder is a high-power clamping cylinder. The high-power clamping cylinder integrates the cylinder and mechanical device into a compact space. The fully sealed structure of the cylinder body 1 is particularly suitable for working environments with dust, welding spatter, and humidity. Simultaneously, under the action of the piston rod, the internal connecting rod of the high-power clamping cylinder eventually reaches the dead point position of the entire mechanism, ensuring the stability of the clamping component on the pressure arm 16 in the clamped state. This prevents the workpiece 5 from falling due to cylinder deprivation, ensuring safety.

[0065] Please seeFigures 1-6 In one embodiment, the system further includes an air pipe 3, one end of which is connected to the control valve 2 via a pipe connector 31, and the other end of which is connected to an air supply system.

[0066] In this embodiment, one end of the air pipe 3 is connected to the control valve 2 via the pipe connector 31, and the other end is connected to the air supply system to quickly supply air to the upper cavity 11 or lower cavity 12 in the cylinder body 1. This method is convenient for disassembly and assembly, improves overall installation efficiency, and enables modular design of the entire system.

[0067] Please see Figure 3 In one embodiment, the cylinder body is further provided with an air inlet 1111 and an air outlet 1211. When the control valve 2 is installed on the cylinder body 1, the air inlet 1111, the air outlet 1211 and the control valve 2 are located on the same surface of the cylinder body 1.

[0068] In this embodiment, when the control valve 2 is installed on the cylinder body 1, the air inlet 1111 and the air outlet 1211 are designed on the same side of the cylinder body 1, which can be the bottom or the side. For example, when it is the bottom, the control valve 2 is designed at the bottom position of the cylinder body 1, so that the cylinder and the valve are set as a whole. After the air source directly enters the control valve 2, the flow direction of the air source can be quickly switched by the control valve so that the air source enters the cylinder, thereby achieving the effect of quickly driving the cylinder piston 13 to move.

[0069] If necessary, when the control valve is located near the cylinder body and connected to the cylinder body through a pipe, the control valve 2 can be designed to be located near the air inlet 1111 and the air outlet 1211 of the cylinder body 1 to shorten the cylinder action time.

[0070] Among them, the control valve 2 can have multiple control methods such as electric control, pneumatic control, and manual control. Taking the electric control valve as an example, when there is an electrical signal, the solenoid valve switches, and the air source changes its path to enter different chambers (upper chamber 11 and lower chamber 12) of the cylinder body 1, thereby realizing the control of the cylinder action.

[0071] In one embodiment, the air inlet 1111 is connected to the upper cavity through the first cavity, and the air outlet 1211 is connected to the lower cavity through the second cavity.

[0072] In this embodiment, by connecting the air inlet 1111 to the first cavity and the air outlet 1211 to the second cavity, the air source supplied by the air pipe can be ensured to enter the cylinder and drive the cylinder piston to reciprocate along the upper cavity direction and the lower cavity direction in the cavity, thereby ensuring that the cylinder piston rod can stably perform the extension and retraction actions.

[0073] Please see Figures 1-6 In one embodiment, when the cylinder piston 13 moves along the upper cavity 11 in the cavity, the air pipe 3, the control valve 2, the second cavity 121 and the lower cavity 12 are sequentially connected to form a first air intake passage, so that the air source enters the second cavity 121 and the lower cavity 12 sequentially under the control of the control valve 2 and can drive the cylinder piston 13 to move along the upper cavity 11. The space of the lower cavity 12 increases relatively with the movement of the cylinder piston 13, and the space of the upper cavity 11 decreases relatively with the movement of the cylinder piston 13. The gas in the upper cavity 11 is pushed to the first cavity 111 by the cylinder piston 13 and can be discharged by the control valve 2.

[0074] When the cylinder piston 13 moves along the lower cavity 12 within the cavity, the air pipe 3, the control valve 2, the first cavity 111, and the upper cavity 11 are sequentially connected to form a second air intake passage. This allows the air source to enter the first cavity 111 and the upper cavity 11 sequentially under the control of the control valve 2, driving the cylinder piston 13 to move along the lower cavity 12. The space of the upper cavity 11 increases relatively with the movement of the cylinder piston 13, while the space of the lower cavity 12 decreases relatively with the movement of the cylinder piston 13. Furthermore, the gas in the lower cavity 12 is pushed to the second cavity 121 by the cylinder piston 13 and can be discharged by the control valve 2.

[0075] In this embodiment, during operation, the flow direction of the air source supplied by the air pipe 3 is controlled by the control valve 2 to drive the cylinder piston 13 to reciprocate along the direction of the upper cavity 11 and the lower cavity 12 in the cavity, thereby ensuring that the cylinder piston rod 14 can stably perform the extension and retraction actions.

[0076] Please see Figures 1-6 In one embodiment, the control valve 2 is equipped with a silencer 21.

[0077] In this embodiment, a muffler 21 is installed on the control valve 2 to reduce the noise generated during cylinder operation. The control valve 2 is also provided with an exhaust port, and the control valve 2 can switch the exhaust port to communicate with the first cavity 111 or the second cavity 121. The muffler 21 is installed at the exhaust port to reduce the noise when the cylinder exhausts.

[0078] Please see Figures 7-9 One embodiment of this utility model also provides a clamping mechanism, including:

[0079] The piston cylinder with control valve 2 as described above;

[0080] The first support block 41 is installed on the cylinder body 1.

[0081] The first pressing block 42 is connected to the other end of the cylinder piston rod 14 via a rotating hinge 43 assembly; wherein, the first pressing block 42 rotates around a preset rotation point of the rotating hinge 43 as the cylinder piston rod 14 moves, so as to cooperate with the first support block 41 to clamp or open the workpiece 5.

[0082] In this embodiment, the advantages and beneficial effects of the piston cylinder with control valve have been described above and will not be repeated here. Since the clamping mechanism includes the piston cylinder with control valve 2, its clamping mechanism also has the same advantages and beneficial effects. In actual use, the support block is fixed, and the piston cylinder with control valve, under the action of an electrical signal, pulls the cylinder joint to reciprocate linearly, causing the pressure block to rotate around the preset rotation point of the rotating hinge 43, and cooperates with the support block to form a clamping part for clamping the workpiece 5. By controlling the distance between the pressure block and the support block, the clamping and opening movements of the pressure block on the workpiece 5 are realized.

[0083] In one embodiment, the rotary hinge 43 assembly includes a cylinder rod connector 431 and a rotary hinge 43, one end of which is connected to the cylinder piston rod 14 via the cylinder rod connector 431, and the other end of which is connected to the first pressure block 42.

[0084] Among them, such as Figures 7-9 The dashed line indicates the workpiece 5 held by the clamping mechanism.

[0085] Please see Figure 10 One embodiment of this utility model also provides a clamping mechanism, including:

[0086] The piston cylinder with control valve 2 as described above;

[0087] The second support block 44 is installed on the cylinder body 1;

[0088] The second pressure block 45 is installed on the pressure arm 16; wherein, the pressure arm 16 drives the second pressure block 45 to rotate around the preset rotation point 151 of the connecting rod hinge 15 as the cylinder piston rod 14 moves, so as to cooperate with the second support block 44 to clamp or open the workpiece 5.

[0089] In this embodiment, the advantages and beneficial effects of the piston cylinder with control valve 2 have been described above and will not be repeated here. Since the clamping mechanism includes the piston cylinder with control valve, it also possesses the same advantages and beneficial effects. In actual use, the pressure block can be opened around the rotation point of the pressure arm 16 by the drive of the internal connecting rod structure, reaching the open state. With the use of the workpiece 5 support block and the positioning pin 46, when the pressure block reaches the clamping state, the workpiece 5 can be positioned and clamped; and it cooperates with the support block to form a clamping part for holding the workpiece 5. By controlling the distance between the pressure block and the support block, the pressure block can perform clamping and opening movements on the workpiece 5.

[0090] In one embodiment, a positioning pin 46 is also provided for positioning the workpiece 5. The positioning pin 46 is connected to the support block, or the positioning pin 46 is connected to the cylinder body 1 via a connector. This improves the positioning and clamping effect of the workpiece 5 and prevents the workpiece 5 from falling off.

[0091] Among them, such as Figure 10 The right-hand dashed line represents the workpiece 5 held by the clamping mechanism, and the left-hand dashed line represents the open state of the second pressure block 45 and the pressure arm 16.

[0092] One embodiment of this utility model also provides a tooling device, including a clamping mechanism as described above that is installed by a fixing component 6, and a main control module, wherein the main control module is electrically connected to the control valve 2.

[0093] In this embodiment, the advantages and beneficial effects of the clamping mechanism have been described above and will not be repeated here. Since the tooling equipment includes the clamping mechanism, the tooling equipment also has the same advantages and beneficial effects. The main control module switches the different states of the control valve 2 through electrical signals, thereby enabling the air source to enter the cavity from the first cavity 111 or the second cavity 121, ensuring the reciprocating motion of the cylinder piston 13.
