Description

Technical Field

[0001] This utility model relates to the field of valve assembly technology, and in particular to a leak-proof hydraulic station quick-reversing clamping valve assembly. Background Technology

[0002] A valve assembly is an integrated control unit composed of multiple valves and related connecting parts and auxiliary components. It is mainly used for centralized control of fluid flow, pressure or direction. It is applied in industrial fields such as hydraulics, pneumatics, water treatment, petrochemicals and power. Its core function is to realize complex fluid control logic through the coordinated work of different valves. Among them, the hydraulic station quick-reversing clamping valve assembly is an integrated control unit in the hydraulic system that realizes the quick reversing and stable clamping function of the actuator. It is applied in machine tool fixtures, automated production lines and heavy machinery that require high-frequency clamping and releasing actions. Its core function is to quickly switch the flow direction of hydraulic oil through multi-valve coordinated control, realize the rapid action of the clamping mechanism, and at the same time ensure the pressure stability under the clamping state to prevent the workpiece from loosening.

[0003] Existing hydraulic station quick-reversing clamping valve assemblies suffer from poor clamping pressure stability and are significantly affected by load fluctuations. When the workpiece has dimensional tolerances or changes in clamping stroke, the pressure compensation response of traditional valve assemblies lags, leading to fluctuations in clamping force and problems such as workpiece slippage or deformation. The current solution is to integrate a pressure sensor and an electro-proportional relief valve to collect the clamping chamber pressure in real time and dynamically adjust the relief pressure through an algorithm, thereby reducing the response time and ensuring stable pressure fluctuations.

[0004] However, traditional valve assemblies are mostly externally connected to pipelines, resulting in a large number of joints, which increases the likelihood of leaks, increases downtime for maintenance, and affects the working efficiency of the valve assembly. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a leak-proof hydraulic station quick-reversing clamping valve group, including a base plate, a negative pressure mechanism provided in the middle of the top wall of the base plate, a vertical shell fixedly connected to the outer side of the top wall of the base plate, and a heat dissipation mechanism provided at the top of the vertical shell;

[0007] The negative pressure mechanism includes a negative pressure fan. The bottom wall of the negative pressure fan is fixedly connected to the right side of the top wall of the base plate. A connecting pipe is connected to the front side of the negative pressure fan. A flow regulating valve is connected to the front end of the connecting pipe.

Multiple locking grooves are opened on the outer side of the bottom wall of the filter shell. The top of the locking posts engages with the locking grooves. Locking plates are rotatably connected to the left and right sides of the top wall of the vertical shell. Locking grooves are opened on the left and right sides of the filter shell. A filter plate is fixedly connected to the top wall of the filter shell. A connecting shell is connected to the middle of the bottom wall of the filter shell. Pulling components are provided on the outer walls of the two locking plates.

[0010] As a further description of the above technical solution:

[0011] The pulling assembly includes two pull rods, with adjacent sides of the two pull rods fixedly connected to the opposite sides of the two locking plates, and a rubber sleeve fixedly connected to the middle of the pull rods.

The connection between the cartridge heads 207 and the valves 208 enables the valve assembly 206 to achieve a modular design, allowing for quick replacement of different valves 208. At the same time, the engagement of the sealing sleeve 205 improves the sealing effect at the connection between the valve 208 and the cartridge head 207 due to the deformation inside the sealing sleeve 205, thereby reducing leakage.

The insert heads 207 are connected to the valves 208 fixedly installed inside, making the valve group equipment 206 modularly designed for quick replacement of different valves 208.

A filter shell 403 is provided on the top of the heat dissipation fan 401. Multiple engaging grooves 408 are opened on the outer side of the bottom wall of the filter shell 403. The tops of the engaging posts 402 engage with the engaging grooves 408. Through the engagement of the engaging posts 402 with the engaging grooves 408, the filter shell 403 is initially fixed. Then, under the rotation of the locking plate 405, it can be locked or separated from the locking groove 404, achieving... To finally lock or disassemble the filter housing 403, locking plates 405 are rotatably connected to the left and right sides of the top wall of the vertical housing 3, and locking grooves 404 are opened on the left and right sides of the filter housing 403, so as to achieve the effect of convenient disassembly and maintenance. The filter plate 406 is fixedly connected to the top wall of the filter housing 403. The filter plate 406 can filter external impurities and reduce the damage of impurity particles to the impeller inside the cooling fan 401. The bottom wall of the filter housing 403 is connected to the middle of the connecting shell 409. The cooling airflow can be guided and transported through the connecting shell 409.

Multiple locking grooves 408 are opened on the outer side of the bottom wall of the filter shell 403 at the top. The top of the locking post 402 engages with the locking groove 408 to complete the initial fixation of the filter shell 403. The locking plate 405 rotates to lock or separate from the locking groove 404, realizing the final locking or disassembly of the filter shell 403, achieving the effect of convenient disassembly and maintenance. At the same time, the filter plate 406 fixed to the top wall of the filter shell 403 can filter external impurities and reduce the damage of impurity particles to the impeller inside the cooling fan 401. The connecting shell 409 connected in the middle of the bottom wall guides and delivers the cooling airflow. The cooling fan 401 starts to draw in the outside air, and finally the airflow completes the heat dissipation treatment of the valve group equipment 206.

[0038] Reference Figure 1 , Figure 4 and Figure 5 The pulling assembly 407 includes two pull rods 4071, with adjacent sides of the two pull rods 4071 fixedly connected to the opposite sides of the two locking plates 405.

The control switch 5 is electrically connected to the negative pressure fan 201, the flow regulating valve 203, the valve group equipment 206, and the cooling fan 401. Multiple heat dissipation slots 411 are provided on the bottom left and right sides of the vertical shell 3, and each heat dissipation slot 411 is provided with an inclined angle.

[0039] Specifically, the locking plate 405 is easily rotated by fixing the pull rod 4071, the rubber sleeve 4072 improves the anti-slip effect, and the control switch 5, which is electrically connected to the negative pressure fan 201, the flow regulating valve 203, the valve group device 206 and the cooling fan 401 respectively, can complete the opening and closing of the equipment.

[0042] Working principle: Multiple cartridge heads 207 are fixed to the front of the valve assembly 206. The front and rear sides of the inner wall of the sealing sleeve 205 are respectively engaged with the front end of the outer wall of the cartridge head 207. By installing the valve 208 on the front side of the cartridge head 207, the modular installation of the valve 208 can be achieved. At the same time, the rear end of the outer wall of the valve 208 is engaged with the sealing sleeve 205 to complete the installation. Subsequently, with the start of the negative pressure fan 201, the flow regulating valve 203 connected to the front end of the connecting pipe 202 controls the airflow. Under the connection of the multi-port pipe 204, the air inside the sealing sleeve 205 is extracted, causing the inside of the sealing sleeve 205 to deform and contract. The deformation of the sealing sleeve 205 improves the sealing effect at the connection between the cartridge head 207 and the valve 208, reduces leakage at the installation position of the valve 208, reduces downtime for maintenance, and improves work efficiency.

[0043] Furthermore, by activating the cooling fan 401, the filter housing 403 can draw in outside air, and the filter plate 406 filters the air, reducing the damage of impurity particles to the impeller inside the cooling fan 401. The connecting shell 409, which is connected in the middle of the bottom wall, guides and delivers the cooling airflow. Finally, the airflow completes the heat dissipation treatment of the valve group equipment 206. Multiple locking grooves 408 opened on the outer side of the bottom wall of the filter housing 403 engage with multiple locking posts 402 fixed on the top wall of the cooling fan 401, completing the initial fixation. The locking plates 405, which are rotatably connected to the left and right sides of the top wall of the vertical shell 3, rotate and lock or separate from the locking grooves 404 opened on the left and right sides of the filter housing 403, realizing the final locking or disassembly of the filter housing 403.
