Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, and in particular to a distributed hydraulic station for multi-station synchronous clamping. Background Technology

[0002] A hydraulic power unit is a device that uses hydraulic oil as its working medium. It converts the mechanical energy of a prime mover into hydraulic energy through a power element, then controls the pressure, flow, and direction of the hydraulic oil through a control element, and finally converts the hydraulic energy into mechanical energy through an actuator. It is widely used in the fields of machinery manufacturing, metallurgy, and chemical engineering, providing power support for clamping, handling, and flipping actions in various machine tools and automated production line equipment. It is one of the important pieces of equipment for realizing the automation and efficiency of industrial production.

[0003] Traditional distributed hydraulic power units for multi-station synchronous clamping mainly consist of an oil tank, a single hydraulic pump, a centralized control valve group, multiple oil supply pipelines, and multiple clamping cylinders. In operation, the hydraulic pump draws hydraulic oil from the tank and pressurizes it. The pressurized hydraulic oil is then delivered to the centralized control valve group via the main oil supply pipeline. From there, the control valve group delivers the oil to the clamping cylinders at each station via branch pipelines, driving the cylinders to clamp the workpiece. When it is necessary to release the workpiece, the control valve group switches the oil circuit, and the hydraulic oil flows back from the clamping cylinders to the oil tank. However, this traditional structure has significant drawbacks: due to the varying distances of each station from the centralized control valve group, the length and resistance of the oil supply pipelines differ, resulting in inconsistent pressure and flow rates of the hydraulic oil reaching each clamping cylinder, making precise synchronous clamping at multiple stations impossible. Furthermore, if a single hydraulic pump fails, the entire hydraulic power unit will stop working, affecting production continuity.

[0004] To address the aforementioned issues, existing technologies have employed multiple hydraulic pumps to supply oil to different workstations, attempting to improve uneven oil distribution by increasing the number of pumps. However, in practical use, the problem of asynchronous clamping at multiple workstations remains unresolved. Due to slight differences in the performance parameters of each hydraulic pump, and the influence of power grid voltage fluctuations and oil temperature changes, the hydraulic oil pressure and flow rate output by each pump are difficult to maintain perfectly consistent. Furthermore, load variations at different workstations can lead to asynchronous clamping cylinder movements, affecting workpiece clamping accuracy and production quality. The root cause of these problems lies in the lack of precise coordinated control of the hydraulic systems at each workstation in existing technologies. The inability to dynamically adjust the hydraulic oil supply based on the real-time status of each workstation results in unsatisfactory synchronous clamping effects at multiple workstations. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a distributed hydraulic station for multi-station synchronous clamping, which aims to improve the problem that multi-station fixtures in the prior art cannot clamp synchronously.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a distributed hydraulic station for multi-station synchronous clamping, including an oil tank, a hydraulic clamping mechanism on the top of the oil tank, and a button locking mechanism on the top of the oil tank;

[0007] The hydraulic clamping mechanism includes multiple motors, which are fixedly connected to the top left and right sides of the oil tank. Each motor's output end is fixedly connected to a vane pump. Each vane pump has a transport pipe connected to its front side. Each transport pipe has a solenoid valve block connected to its right side. Each solenoid valve block has an oil inlet pipe connected to its right front side and an oil outlet pipe connected to its right rear side. A base is provided between adjacent oil inlet and oil outlet pipes. Each base has a tightening assembly on its left and right sides.

[0009] The button locking mechanism includes two threaded seats, which are threadedly connected to the front and rear sides of the top center of the oil tank, respectively. A conical cylinder is slidably connected to the inner wall of each of the two threaded seats. A trapezoidal block is slidably connected to the bottom of the inner wall of each of the two conical cylinders. Two ball bearings are slidably connected to the top of each of the two trapezoidal blocks. Multiple ball bearings are slidably connected to the bottom of the outer wall of the corresponding conical cylinder. A support rod is fixedly connected to the top of each of the two trapezoidal blocks. A spring is slidably connected to the middle of the outer wall of each of the two support rods. The bottom of each spring is fixedly connected to the middle of the inner wall of the corresponding conical cylinder. A button is fixedly connected to the top of each of the two support rods. The bottom of each button is fixedly connected to the top of the corresponding spring.

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

[0011] The tightening assembly includes multiple threaded grooves, which are respectively opened on the left and right sides of the base. The inner walls of the multiple threaded grooves are threaded with threaded cylinders, and the inner walls of the multiple threaded cylinders are provided with sliding grooves. The outer walls of the multiple oil inlet pipes and the multiple oil outlet pipes are fixedly connected with sliders, and the multiple sliders are slidably connected to the corresponding sliding grooves.

[0012] As a further description of the above technical solution:

[0013] The control component includes a support plate, which is fixedly connected to the front left side of the fuel tank. A main control screen is fixedly connected to the top right side of the support plate. Multiple status lights are fixedly connected to the top center of the support plate. An emergency stop button is fixedly connected to the top left side of the support plate.

[0014] As a further description of the above technical solution:

[0015] Each of the multiple transport pipes is connected to a pressure pipe at its middle section, and each of the multiple pressure pipes is fixedly connected to a pressure gauge at its middle section.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor drives the vane pump to operate, and the vane pump generates continuous pressure to deliver high-pressure oil to the solenoid valve block, so that the solenoid valve block completes the valve core switching action, opens the oil inlet passage, and smoothly transmits the power to the hydraulic fixture through the linkage mechanism, so that all the grippers reach the preset clamping force at the same time, realizing the synchronous clamping of multi-station workpieces, solving the problem that multi-station fixtures cannot clamp synchronously in the prior art, and improving the workpiece processing accuracy and production efficiency.

[0024] 2. In this utility model, after replacing the hydraulic clamp, releasing the button causes the spring to push the support rod and trapezoidal block back to their original position under the action of elastic potential energy. The slider, guided by the conical surface of the inner wall of the conical cylinder and under its own gravity, rolls along the inclined plane and re-locks into the groove of the conical cylinder and the threaded seat. The self-locking characteristic of the trapezoidal structure forms a stable lock, realizing the quick fixation of the base. This structure solves the problem of inconvenient clamp disassembly in existing devices, allowing replacement to be completed without tools, reducing auxiliary time, and improving the versatility and ease of maintenance of the equipment.

Detailed Implementation

[0033] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 4 and Figure 6The present invention provides an embodiment of a distributed hydraulic station for multi-station synchronous clamping, including an oil tank 1 for storing hydraulic oil and providing oil reserves for the entire hydraulic system. A hydraulic clamping mechanism 2 is provided on the top of the oil tank 1 to realize the clamping action of the workpiece. A button locking mechanism 3 is provided on the top of the oil tank 1 to quickly lock and release related components for easy maintenance and replacement.

[0035] The hydraulic clamping mechanism 2 includes multiple motors 201, providing a power source for the hydraulic system. The multiple motors 201 are fixedly connected to the top left and right sides of the oil tank 1, respectively. Each motor 201 has a vane pump 202 fixedly connected to its output end, pressurizing and outputting the hydraulic oil from the oil tank 1. Each vane pump 202 has a transport pipe 203 connected to its front side, transporting the pressurized hydraulic oil. Each transport pipe 203 has a solenoid valve block 204 connected to its right end, controlling the on / off state and flow direction of the hydraulic oil. Each solenoid valve block 204 has an inlet pipe 205 connected to its right front end, which delivers hydraulic oil to the actuator. Each solenoid valve block 204 also has an outlet pipe 206 connected to its right rear end, which delivers the returning hydraulic oil back to the oil tank 1. A base 207 is positioned between adjacent inlet pipes 205 and outlet pipes 206 to provide a mounting foundation for the hydraulic clamp 209 and transmit hydraulic power. Tightening assemblies 208 are located on both the left and right sides of the base 207 to facilitate the connection of the inlet pipes 205 and outlet pipes 206. The oil pipe 206 is sealed and fixed to the base 207. Multiple hydraulic clamps 209 are fixedly connected to the top of the base 207, which directly contact the workpiece to achieve clamping action. The control component 210 is set on the left side of the front end of the oil tank 1 to control the operation of the entire hydraulic station and monitor its working status. The tightening component 208 includes multiple threaded grooves 2081, which provide a threaded connection base for the threaded cylinder 2082. Multiple threaded grooves 2081 are respectively opened on the left and right sides of the base 207. The inner walls of multiple threaded grooves 2081 are threadedly connected to the threaded cylinder 2082, which cooperate with the threaded grooves 2081 to achieve connection and fixation. The inner walls of multiple threaded cylinders 2082 are provided with sliding grooves 2083 to provide sliding guides for the sliders 2084. The outer walls of multiple oil inlet pipes 205 and multiple oil outlet pipes 206 are fixedly connected to sliders 2084, which cooperate with the sliding grooves 2083 to ensure the stability and sealing of the pipeline connection. Multiple sliders 2084 are slidably connected to the corresponding sliding grooves 2083.

[0036] Specifically, when multi-station synchronous clamping is required, the operator issues a command through the control component 210, and multiple motors 201 start simultaneously, driving the corresponding vane pumps 202 to operate. The vane pumps 202 draw hydraulic oil from the oil tank 1 and pump it into the solenoid valve block 204 through the transport pipe 203. After receiving the signal, the solenoid valve block 204 opens the oil inlet passage, and the high-pressure oil is delivered to the base 207 through the oil inlet pipe 205. At this time, in the tightening component 208, the slider 2084 slides along the slide groove 2083, cooperating with the threaded connection between the threaded cylinder 2082 and the threaded groove 2081, ensuring that the oil inlet pipe 205 and the base 207 are connected. 7. With the seal connected, the hydraulic oil pressure inside the base 207 increases, driving multiple hydraulic clamps 209 at the top to move synchronously. Because the parameters of each motor 201 and vane pump 202 are consistent, and the solenoid valve block 204 is controlled synchronously, the oil is evenly distributed, and each hydraulic clamp 209 reaches the same clamping force in the same time. After clamping is completed, the solenoid valve block 204 switches the path, and the hydraulic oil flows back to the oil tank 1 through the oil outlet pipe 206. If adjustment is required, the solenoid valve block 204 is precisely controlled by the control component 210 to ensure that the multiple stations are always synchronized. This process achieves efficient and precise multi-station synchronous clamping, improving work efficiency.

[0037] Reference Figure 1 , Figure 4 and Figure 5 The button locking mechanism 3 includes two threaded seats 301, providing an installation base for the conical cylinder 302 and fixing it to the oil tank 1 via threaded connection. The two threaded seats 301 are respectively threaded to the front and rear sides of the top center of the oil tank 1. The inner walls of both threaded seats 301 are slidably connected to the conical cylinder 302, achieving a locking function through the sliding fit with the threaded seats 301 and their own conical structure. The bottom of the inner walls of both conical cylinders 302 are slidably connected to trapezoidal blocks 303, which push the sliders 304 to achieve the locking action. The tops of both trapezoidal blocks 303 are slidably connected to two sliders 304, which, under the action of the trapezoidal blocks 303 and the conical cylinders 302, clamp the threaded seats 301 to achieve locking. Multiple The sliders 304 are slidably connected to the bottom of the outer wall of the corresponding conical cylinder 302. The top of each of the two trapezoidal blocks 303 is fixedly connected to a support rod 305, which connects the trapezoidal block 303 and the button 307 and transmits the pressing force. The middle of the outer wall of each of the two support rods 305 is slidably connected to a spring 306, which realizes the reset of the button 307 and the trapezoidal block 303 through its own elastic deformation. The bottom of each of the two springs 306 is fixedly connected to the middle of the inner wall of the corresponding conical cylinder 302. The top of each of the two support rods 305 is fixedly connected to a button 307, which allows the operator to apply external force to control the opening and closing of the locking device. The bottom of each of the two buttons 307 is fixedly connected to the top of the corresponding spring 306.

[0038] Specifically, when it is necessary to fix the base 207, it is aligned with the mounting position between the two threaded seats 301 and inserted. At this time, the conical cylinder 302 slides along the inner wall of the threaded seat 301 under the downward pressure of the base 207. The trapezoidal block 303 moves down with the conical cylinder 302, and its inclined surface pushes the slider 304 to slide along the bottom of the inner wall of the conical cylinder 302. The slider 304 is engaged in the groove on the inner wall of the threaded seat 301, forming a preliminary lock. The spring 306 is in the natural state, and the button 307 at the top of the support rod 305 remains in the pop-out state. If reinforcement is required, the button 307 is pressed, and the support rod 305 drives the trapezoidal block 303 to move down, further squeezing the slider 304, so that it fits tightly against the inner wall of the threaded seat 301. The self-locking feature of the structure ensures the stable installation of the base 207. During disassembly, press the front and rear buttons 307 simultaneously with both hands. The support rod 305 compresses the spring 306 and moves the trapezoidal block 303 upward. The slider 304, no longer compressed by the trapezoidal block 303, disengages from the slot of the threaded seat 301 under the rebound action of the conical cylinder 302 and slides back along the bottom of the outer wall of the conical cylinder 302. At this time, the conical cylinder 302 can slide freely along the inner wall of the threaded seat 301, and the base 207 can be easily pulled out. After releasing the button 307, the spring 306 resets, driving all components back to their initial positions, ready for the next locking operation. The entire process requires no tools and achieves rapid loading and unloading through the linkage of the mechanical structure, improving the convenience of equipment maintenance.

[0039] Reference Figure 1 , Figure 2 and Figure 4 The control component 210 includes a support plate 2101, which supports various control components and is fixedly connected to the oil tank 1. The support plate 2101 is fixedly connected to the front left side of the oil tank 1. The main control screen 2102 is fixedly connected to the top right side of the support plate 2101, which allows operators to input commands, set parameters, and display system operating information. Multiple status lights 2103 are fixedly connected to the top center of the support plate 2101 to intuitively display the working status of each workstation or system. An emergency stop button 2104 is fixedly connected to the top left side of the support plate 2101 to quickly cut off the system operation in an emergency to ensure safety. Pressure pipes 4 are connected to the middle of multiple transport pipes 203. Pressure gauges 5 are fixedly connected to the middle of multiple pressure pipes 4 to display the hydraulic oil pressure in the transport pipes 203 in real time so that operators can grasp the system pressure status.

[0040] Specifically, in the control component 210, the support plate 2101 serves as a load-bearing element. The hydraulic system can be started, stopped, and its parameters can be set via the main control screen 2102. The status lights 2103 display the working status of each station in real time, with green lights indicating normal operation and red lights indicating a fault. The emergency stop button 2104 cuts off the system power immediately when pressed in an emergency. The pressure pipe 4 is connected to the transport pipe 203, and the pressure gauge 5 monitors the pressure of each pipeline in real time to ensure system stability and facilitate timely detection of abnormalities.

[0041] Reference Figure 1 , Figure 2 and Figure 3 A level gauge 6 is fixedly connected to the middle of the front end of the outer wall of the oil tank 1, which displays the hydraulic oil level in the tank in real time, allowing operators to easily observe the oil level. Two screws 7 are threadedly connected to the front of the level gauge 6, securing it firmly to the oil tank 1 to prevent loosening during equipment operation. Both screws 7 are threaded into the oil tank 1. A filling trough 8 is connected to the middle of the front end of the oil tank 1, replenishing hydraulic oil to continuously supply the system. An oil outlet trough 9 is connected to the right side of the front end of the oil tank 1 for oil replacement. When hydraulic oil is being pumped out or during maintenance, the oil in tank 1 is drained. Multiple support columns 10 are fixedly connected to the bottom of tank 1 to support it and keep it at a certain distance from the ground to prevent ground moisture from affecting it. The bottom of the multiple support columns 10 is fixedly connected to the same base 11, which increases the contact area between the equipment and the ground and improves the stability of the entire device. Screws 12 are threaded around the top of base 11 to fix it to the mounting surface and prevent the equipment from shifting during operation.

[0042] Specifically, the level gauge 6 of the oil tank 1 is fixed by screw 7 and displays the oil level in real time, making it easy to observe whether the oil is sufficient. When oil needs to be added, it is added through the oil filling tank 8. The oil outlet tank 9 is used to discharge waste oil or drain oil during maintenance. The support column 10 and the base 11 support the entire device. Screw 12 fixes the base 11 to ensure the stability of the equipment. These components work together to ensure the oil tank 1 stores and supplies oil and the overall stability of the equipment.

[0043] Working Principle: When simultaneous clamping of workpieces at multiple workstations is required, the operator can send a start command through the main control screen 2102. At this time, the motor 201 starts running, and its output shaft drives the vane pump 202 into working condition. The vane pump 202 uses the volume change generated by the rotation of the rotor to draw hydraulic oil from the bottom of the oil tank 1 through the suction port. After being pressurized, it is pumped into the internal oil circuit block of the solenoid valve block 204 through the high-pressure transport pipe 203. The preset diversion channel in the oil circuit block will evenly distribute the high-pressure oil to each solenoid valve group. The operator sends a reversing signal to the solenoid valve block 204 through the main control screen 2102. After the solenoid coil is energized, it pushes the valve core to move, so that the oil inlet channel and the branch oil circuit of each workstation form a passage. The high-pressure oil is then transported to the corresponding workstation base 207 through the oil inlet pipe 205. The piston inside the base 207 slides along the cylinder under the action of oil pressure. The linkage mechanism drives the grippers of the hydraulic clamp 209 to close synchronously, thereby clamping multiple workpieces. When the workpiece is finished and the grippers need to be released, the operator sends a reverse command through the main control screen 2102. The valve core of the solenoid valve block 204 switches to the return oil position under the action of the return spring 306, so that the hydraulic oil in each base 207 flows back into the solenoid valve block 204 through the return oil pipe, and then enters the low-pressure side of the vane pump 202 through the return oil channel. At this time, the vane pump 202 is in the unloaded state, and the oil is transported to the condenser built into the oil tank 1 through the pipeline. Finally, the filtered clean oil flows back to the bottom of the oil tank 1, completing the entire hydraulic cycle. This solves the problem that the existing device cannot perform synchronous clamping at multiple positions. When the hydraulic clamping mechanism 2 of a certain position fails, the main control screen 2102 is controlled to cut off the power to this position, so as to carry out maintenance without affecting the operation of other hydraulic clamping mechanisms 2.

[0044] When the hydraulic clamp 209 needs to be changed according to different workpiece sizes, the operator does not need to use tools. They simply press the buttons 307 on the front and rear sides of the base 207 simultaneously with both hands. Pressing the buttons 307 causes the support rod 305, which is fixed to it, to move downwards along the guide hole. The inclined structure at the bottom of the support rod 305 pushes the slider 304 to overcome the elastic force of the spring 306 and disengage from the positioning groove of the tapered cylinder 302. The slider 304 slides down the inner wall of the threaded seat 301 into the receiving cavity. After the tapered cylinder 302 loses its radial constraint, it separates from the threaded seat 301. At this point, the base 207 can be directly removed from the mounting plate. After removing the fixture from the mounting base and replacing it with a new one, press button 307 again to keep the slider 304 in the retracted state. Insert the connecting end of the base 207 into the threaded seat 301. After releasing button 307, the support rod 305 returns to its original position under the action of the return spring 306. The slider 304 rolls along the conical surface of the conical cylinder 302 under the thrust of the spring 306 and embeds itself into the trapezoidal inner wall groove of the threaded seat 301. The self-locking property of the trapezoidal structure makes the conical cylinder 302 and the threaded seat 301 fit tightly together, realizing the rapid fixation of the base 207 and solving the problem of inconvenient disassembly of the fixture in the existing device.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
