Description

Technical Field

[0001] This invention relates to the field of hydraulic clamp technology, specifically to an intelligent energy-saving hydraulic clamp and its control method. Background Technology

[0002] Hydraulic pliers are pliers powered by hydraulic pressure. They achieve functions such as cutting and crimping through the pressure generated by the hydraulic system. Energy-saving hydraulic pliers are based on traditional hydraulic pliers and use some technical means to reduce energy consumption and improve energy utilization efficiency. The principle is to use a hydraulic pump to press hydraulic oil into a hydraulic cylinder, which pushes the piston to move, thereby driving the jaws to complete the work. They have strong cutting and clamping forces, are easy to operate and efficient, and can save manpower and time.

[0003] Hydraulic clamps are typically used to clamp hard objects such as steel pipes and reinforcing bars because they provide strong clamping force. However, due to the hardness of the objects being clamped, they are prone to jamming after prolonged use. Jamming leads to uneven operation and causes the clamped objects to loosen or fall off, affecting the safety and quality of the operation. However, existing hydraulic clamps cannot detect the smoothness of operation in time, so jamming cannot be repaired in a timely manner.

[0004] Therefore, we propose an intelligent energy-saving hydraulic clamp and its control method to solve the problems mentioned above. Summary of the Invention

[0011] Preferably, a fixed rod is fixedly connected between the inner walls of one of the movable slots, a push rod is rotatably connected to the outer surface of the fixed rod, a connecting hole is opened on the outer surface of the push rod, a connecting rod is rotatably connected to the inner wall of the connecting hole, a push block is fixedly connected between the two ends of the connecting rod, a movable hole is opened on one side of the push block, and the inner wall of the movable hole is fixedly connected to the outer surface of the movable rod located below.

[0012] Preferably, a drive assembly is provided on the top of the support plate. The drive assembly includes a hydraulic pump. Two delivery pipes are fixedly connected to the outer surface of the hydraulic pump. One end of each delivery pipe is fixedly connected to the outside of the hydraulic cylinder. An oil tank is provided on the inner top surface of the support frame. An oil pipe is provided on the outer surface of the hydraulic pump. One end of the oil pipe extends into the interior of the oil tank.

[0013] Preferably, detection components are fixedly connected to the outer surfaces of both grippers. Each detection component includes two detection claws. A connecting plate is fixedly connected to the outer surface of each detection claw. A sliding groove is formed on the outer surface of each connecting plate. A slider is slidably connected to the inner wall of each sliding groove. A positioning plate is fixedly connected to the outer surface of each slider. Multiple limiting telescopic rods are fixedly connected between the outer surface of each slider and the inner wall of each sliding groove. A reinforcing spring is provided on the outer surface of each limiting telescopic rod. The two ends of each reinforcing spring are fixedly connected to the outer surface of the slider and the inner wall of the sliding groove, respectively. A pressing rod is fixedly connected between the two connecting plates.

[0014] Preferably, a mounting bracket is fixedly connected to the outer surface of both grippers, and a pressure sensor is provided on the inner wall of both mounting brackets, with the position of each pressure sensor corresponding to the position of each pressing bar.

[0015] A control method for an intelligent energy-saving hydraulic clamp includes the following steps:

[0016] S1. First, hydraulic oil is injected into the oil tank and the hydraulic pump is started. Under the pressure of the hydraulic pump, the hydraulic oil inside the oil tank is drawn out through the oil pipe. The two delivery pipes are connected to the inlet and outlet of the hydraulic cylinder respectively. Its driving principle is the existing known technology. The hydraulic pump sends the hydraulic oil inside the oil tank into the hydraulic cylinder, which pushes the piston inside the hydraulic cylinder to move, thereby driving the gripper to complete the clamping action.

[0017] S2. During clamping, the extension of the hydraulic cylinder pushes the reinforcing rod of the gripper forward. At this time, the corner position where the gripper is connected to the movable rod does not move, so the gripper will rotate around the movable rod as the rotation center. At this time, the fixed rod pushes the push rod forward. When pushing, it will push the side of the push block where the connecting rod is installed outward. The movable rod located below is fixedly connected to the gripper located below and the movable hole. When the push block is pushed, it will drive the gripper located below to rotate around the movable rod connected to it as the center, thereby realizing the clamping of the two grippers. Conversely, when the hydraulic cylinder retracts, the two grippers are unfolded.

[0018] S3. During the clamping process, the detection claw will be pushed in the opposite direction by the object. The connecting plate will push the pressing bar towards the pressure sensor. The pressure sensor will then transmit the detected pressure to the controller. When the controller detects that the pressure value detected by the pressure sensor exceeds the normal range, it will control the hydraulic pump to be shut down. When the clamping is completed, the connecting plate can drive the detection claw to return to its original position under the rebound action of the reinforcing spring. In addition, the position of the detection claw is beyond the anti-slip teeth. When clamping an object, the surface of the object contacts the detection claw first.

[0019] S4. An infrared beam is emitted by an infrared sensor and received by a receiving board. A liquid crystal layer is coated on the receiving surface of the receiving board. When heated by infrared rays, the arrangement of liquid crystal molecules in the liquid crystal layer changes, resulting in a color change that displays the trajectory of the infrared rays. At this time, the trajectory formed on the surface of the receiving board can be captured in real time by a vision sensor, thus recording the smoothness of the trajectory and the formation time. When the trajectory is smooth, it indicates that the hydraulic clamp does not jam during operation. If the trajectory is not smooth, it indicates that there is jamming. The vision sensor transmits the abnormal information to the controller.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. During use, an infrared sensor emits an infrared beam, which is received by a receiving board. The receiving surface of the receiving board is coated with a liquid crystal layer. When heated by infrared rays, the arrangement of liquid crystal molecules in the liquid crystal layer changes, resulting in a color change that displays the trajectory of the infrared rays. Through the imaging function of the vision sensor, the trajectory formed on the surface of the receiving board can be captured in real time, thereby recording the smoothness of the trajectory and the formation time. When the trajectory is smooth, it indicates that the hydraulic clamp does not jam during operation. If the trajectory is not smooth, it indicates that there is jamming. The vision sensor transmits the abnormal information to the controller, which facilitates timely maintenance of the hydraulic clamp by the staff.

[0022] 2. During use, the pressing bar is pushed towards the pressure sensor via the connecting plate. The pressure sensor then transmits the detected pressure to the controller. Since different objects can withstand different maximum pressures, when the controller detects that the pressure value detected by the pressure sensor exceeds the normal range, it controls the shutdown of the hydraulic pump to prevent the object from being damaged during clamping. The slider slides inside the slide groove, and the positioning plate can prevent the connecting plate from falling off during sliding. When clamping is completed, the rebound action of the reinforcing spring can cause the connecting plate to drive the detection claw to return to its original position.

[0023] 3. During use, the hydraulic pump sends hydraulic oil from the tank into the hydraulic cylinder, pushing the piston inside the cylinder to move, thereby driving the grippers to complete the clamping action. During clamping, the extension of the hydraulic cylinder, connected by the push rod and push block, drives the two grippers to clamp. Conversely, when the hydraulic cylinder retracts, the two grippers unfold. Multiple anti-slip teeth can increase the anti-slip effect when clamping objects, preventing the objects from shifting position during operation. In addition, the support frame can support the entire device. The support plate is used to install the hydraulic pump, while the diagonal brace and triangular plate use the stability of the triangular structure to prevent tipping. Attached Figure Description

[0035] Reference Figure 1-8As shown: An intelligent energy-saving hydraulic clamp includes a support assembly 3 and a clamping assembly 1. The clamping assembly 1 is disposed on top of the support assembly 3 and includes two fixed frames 101. Rotating holes 104 are provided at the three corners of the two fixed frames 101. Movable rods 118 are rotatably connected between the inner walls of every two rotating holes 104. Grippers 105 are provided on the outer surfaces of both movable rods 118. A connecting strip 9 is fixedly connected to the outer surface of one of the grippers 105. A receiving plate 10 is provided on the outer surface of the connecting strip 9. One side of the receiving plate 10 is coated with a liquid crystal layer 12. The outer surface of another gripper 105 is fixedly connected to a support plate 8. An infrared sensor 7 is set on the top of the support plate 8. The emitting end of the infrared sensor 7 is matched with the inner wall of the receiving plate 10. The support assembly 3 includes a support frame 301. A controller 11 is set on the top of the support frame 301. A fixed base plate 303 is fixedly connected to one side of the outer surface of the support frame 301 near the bottom. A support rod 6 is fixedly connected to the top of the fixed base plate 303. A vision sensor 5 is set on the top of the support rod 6.

[0036] like Figure 1 and Figure 2 As shown, a triangular plate 302 is fixedly installed between one outer surface of the support frame 301 and the top of the fixed base plate 303. A support plate 304 is fixedly connected to the other outer surface of the support frame 301. A diagonal brace 305 is fixedly connected between the bottom of the support plate 304 and the other outer surface of the support frame 301. The support frame 301 can support the entire device. The support plate 304 is used to install the hydraulic pump 401. The diagonal brace 305 and the triangular plate 302 both use the stability of the triangular structure to prevent tipping.

[0037] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, each movable rod 118 has a stop block 114 fixedly connected to both ends. A support plate 102 is fixedly connected between the two fixed frames 101. An installation block 103 is fixedly connected to the outer surface of the support plate 102. The installation block 103 is installed on the top of the support frame 301 by bolts. The stop block 114 can prevent the movable rod 118 from falling off. The support plate 102 can connect the two fixed frames 101 into a whole, increasing the stability of the two fixed frames 101 during use. The installation block 103 has an installation function. The bolt installation method has the advantage of being detachable.

[0038] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, multiple anti-slip teeth 106 are fixedly connected to the opposite side of the two grippers 105. Movable grooves 107 are provided at the opposite corners of the two grippers 105. An installation groove 115 is provided at the other corner of one of the grippers 105. The multiple anti-slip teeth 106 can increase the anti-slip effect when gripping objects and prevent the objects from shifting position during operation.

[0039] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a reinforcing rod 116 is fixedly connected between the inner walls of the mounting groove 115. A rotating block 117 is rotatably connected to the outer surface of the reinforcing rod 116 and the outer surface of another movable rod 118. A hydraulic cylinder 405 is fixedly connected between the two rotating blocks 117. The movable installation of the two rotating blocks 117 allows the hydraulic cylinder 405 to move flexibly during operation.

[0040] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a fixed rod 108 is fixedly connected to the inner wall of one of the movable slots 107. A push rod 109 is rotatably connected to the outer surface of the fixed rod 108. A connecting hole 110 is opened on the outer surface of the push rod 109. A connecting rod 111 is rotatably connected to the inner wall of the connecting hole 110. A push block 112 is fixedly connected between the two ends of the connecting rod 111. A movable hole 113 is opened on one side of the push block 112. The inner wall of the movable hole 113 is fixedly connected to the outer surface of the movable rod 118 located below. The corner position where the gripper 105 located above is connected to the movable rod 118 does not move. Therefore, the gripper... 105 will rotate around the movable rod 118 as the rotation center. At this time, the fixed rod 108 pushes the push rod 109 forward. When pushing, it will push the side of the push block 112 with the connecting rod 111 installed outward. The movable rod 118 located below is fixedly connected to the gripper 105 located below and the movable hole 113. When the push block 112 is pushed, it will drive the gripper 105 located below to rotate around the movable rod 118 connected to it as the center, thereby realizing the clamping of the two grippers 105. Conversely, when the hydraulic cylinder 405 retracts, the two grippers 105 are unfolded.

[0041] like Figure 1-6As shown, a drive assembly 4 is provided on the top of the support plate 304. The drive assembly 4 includes a hydraulic pump 401. Two delivery pipes 404 are fixedly connected to the outer surface of the hydraulic pump 401. One end of each delivery pipe 404 is fixedly connected to the outside of the hydraulic cylinder 405. An oil tank 402 is provided on the inner top surface of the support frame 301. An oil pipe 403 is provided on the outer surface of the hydraulic pump 401. One end of the oil pipe 403 passes through the inside of the oil tank 402. The hydraulic pump 401 sends the hydraulic oil inside the oil tank 402 into the hydraulic cylinder 405, which pushes the piston inside the hydraulic cylinder 405 to move, thereby driving the gripper 105 to complete the clamping action. During clamping, the extension of the hydraulic cylinder 405 and the fact that both rotating blocks 117 are movably installed make the movement path of the hydraulic cylinder 405 flexible.

[0042] like Figure 1-3 , Figure 7 and Figure 8 As shown, detection components 2 are fixedly connected to the outer surfaces of both grippers 105. Each detection component 2 includes two detection claws 201. A connecting plate 202 is fixedly connected to the outer surface of each detection claw 201. A groove 203 is formed on the outer surface of each connecting plate 202. A slider 207 is slidably connected to the inner wall of each groove 203. A positioning plate 206 is fixedly connected to the outer surface of each slider 207. Multiple limiting telescopic rods 204 are fixedly connected between the outer surface of each slider 207 and the inner wall of each groove 203. A reinforcing spring 205 is provided on the outer surface of each limiting telescopic rod 204. The two ends of each reinforcing spring 205 are fixedly connected to the outer surface of the slider 207 and the inner wall of the groove 203, respectively. A pressing device is fixedly connected between the two connecting plates 202. When clamping is in progress, the detection claws 201 on both sides of the two grippers 105 will simultaneously contact the object. During the clamping process, the detection claws 201 will be pushed in the opposite direction by the object. The connecting plate 202 will push the pressing rod 208 towards the pressure sensor 210. The pressure sensor 210 will then transmit the detected pressure to the controller 11. Since different objects can withstand different maximum pressures, the slider 207 slides inside the slide groove 203. During the sliding, the positioning plate 206 can prevent the connecting plate 202 from falling off. When the clamping is completed, the reinforcing spring 205 can cause the connecting plate 202 to drive the detection claws 201 to return to their original position. The mounting bracket 209 serves to install the pressure sensor 210. In addition, the position of the detection claws 201 extends beyond the anti-slip teeth 106.

[0043] like Figure 1-3 , Figure 7 and Figure 8As shown, mounting brackets 209 are fixedly connected to the outer surfaces of the two grippers 105. Pressure sensors 210 are installed on the inner walls of the two mounting brackets 209. The position of each pressure sensor 210 corresponds to the position of each pressing rod 208. When the controller 11 detects that the pressure value detected by the pressure sensor 210 exceeds the normal range, it controls the hydraulic pump 401 to shut down to prevent the object from being damaged during clamping.

[0044] In this invention, during use, hydraulic oil is first injected into the oil tank 402, and the hydraulic pump 401 is started. Under the pressure of the hydraulic pump 401, the hydraulic oil inside the oil tank 402 is drawn out through the oil pipe 403. Two delivery pipes 404 are respectively connected to the inlet and outlet of the hydraulic cylinder 405. The driving principle is the existing known technology. The hydraulic pump 401 sends the hydraulic oil inside the oil tank 402 into the hydraulic cylinder 405, pushing the piston inside the hydraulic cylinder 405 to move, thereby driving the gripper 105 to complete the clamping action. During clamping, the extension of the hydraulic cylinder 405 and the movable installation of the two rotating blocks 117 make the movement path of the hydraulic cylinder 405 flexible, thereby pushing the reinforcing rod 116 of the gripper 105 forward. At this time, the corner position where the gripper 105 is connected to the movable rod 118 does not move, so the gripper 105 will rotate around the movable rod 118 as the rotation center. At this time, the fixed rod 108 pushes the push rod 109 forward. When pushing, it will push the side of the push block 112 where the connecting rod 111 is installed outward. The movable rod 118 located below is fixedly connected to the gripper 105 located below and the movable hole 113. So when the push block 112 is pushed, it will drive the gripper 105 located below to rotate around the movable rod 118 connected to it as the center, thereby realizing the clamping of the two grippers 105. Conversely, when the hydraulic cylinder 405 retracts, the two grippers 105 are unfolded. The multiple anti-slip teeth 106 can increase the anti-slip effect when clamping objects. To prevent the object from shifting position during operation, initially, the pressing rod 208 is in contact with the surface of the pressure sensor 210. During clamping, the detection claws 201 on both sides of the two grippers 105 simultaneously contact the object. During clamping, the detection claws 201 are pushed in the opposite direction by the object, pushing the pressing rod 208 towards the pressure sensor 210 via the connecting plate 202. The pressure sensor 210 then transmits the detected pressure to the controller 11. Since different objects can withstand different maximum pressures, when the controller 11 detects that the pressure value detected by the pressure sensor 210 exceeds the normal range, it shuts off the hydraulic pump 401 to prevent damage to the object during clamping. The slider 207 slides inside the groove 203. Furthermore, the positioning plate 206 prevents the connecting plate 202 from falling off during sliding. When clamping is complete, the reinforcing spring 205 allows the connecting plate 202 to move the detection claw 201 back to its original position. The mounting bracket 209 serves to mount the pressure sensor 210. Additionally, the detection claw 201 extends beyond the anti-slip teeth 106. When clamping an object, the object's surface contacts the detection claw 201 first. The anti-slip teeth 106 are made of a soft material and will not damage the object's surface. During the continuous opening and clamping process of the two grippers 105, an infrared beam is emitted by the infrared sensor 7. The emitted infrared beam is received by the receiving plate 10. The receiving surface of the receiving plate 10 is coated with a liquid crystal layer 12. When heated by infrared radiation...The arrangement of liquid crystal molecules in the liquid crystal layer 12 changes, resulting in a color change that displays the trajectory of infrared light. The liquid crystal typically exhibits a gel-like form and can be coated onto the surface of the receiving plate 10, ensuring uniform coating. The visual sensor 5 captures the trajectory formed on the surface of the receiving plate 10 in real time, recording the smoothness and formation time of the trajectory. A smooth trajectory indicates that the hydraulic clamp operates without jamming; an uneven trajectory indicates jamming. The visual sensor 5 transmits this abnormal information to the controller 11, facilitating timely maintenance of the hydraulic clamp. Furthermore, the support frame 301 provides support for the entire device. The support plate 304 houses the hydraulic pump 401, while the diagonal brace 305 and triangular plate 302 utilize the stability of a triangular structure to prevent tipping.

[0045] The wiring diagrams of the pressure sensor 210, hydraulic pump 401, hydraulic cylinder 405, vision sensor 5, infrared sensor 7, and controller 11 in this invention are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the pressure sensor 210, hydraulic pump 401, hydraulic cylinder 405, vision sensor 5, infrared sensor 7, and controller 11 will not be explained in detail.

[0046] Although the present invention 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 invention should be included within the protection scope of the present invention.

The intelligent energy-saving hydraulic clamp according to claim 8, characterized in that: The outer surfaces of the two grippers (105) are fixedly connected with mounting brackets (209), and the inner walls of the two mounting brackets (209) are provided with pressure sensors (210). The position of each pressure sensor (210) corresponds to the position of each pressing bar (208).

10. A control method for an intelligent energy-saving hydraulic clamp, characterized in that, The intelligent energy-saving hydraulic clamp according to claim 9 includes the following steps: S1. First, hydraulic oil is injected into the oil tank (402), and the hydraulic pump (401) is started. Under the pressure of the hydraulic pump (401), the hydraulic oil inside the oil tank (402) is drawn out through the oil pipe (403). The two delivery pipes (404) are connected to the inlet and outlet of the hydraulic cylinder (405) respectively. The hydraulic pump (401) sends the hydraulic oil inside the oil tank (402) into the hydraulic cylinder (405), which pushes the piston inside the hydraulic cylinder (405) to move, thereby driving the gripper (105) to complete the clamping action. S2. During clamping, the extension of the hydraulic cylinder (405) pushes the reinforcing rod (116) of the gripper (105) forward. At this time, the corner position where the gripper (105) is connected to the movable rod (118) does not move, so the gripper (105) will rotate around the movable rod (118) as the rotation center. At this time, the fixed rod (108) pushes the push rod (109) forward. During the push, the connecting rod (1) installed in the push block (112) will be pushed forward. 11) Push one side outward, and the movable rod (118) located below is fixedly connected to the gripper (105) located below and the movable hole (113). When the push block (112) is pushed, it will drive the gripper (105) located below to rotate around the movable rod (118) connected to it, thereby realizing the clamping of the two grippers (105). Conversely, when the hydraulic cylinder (405) retracts, the two grippers (105) are unfolded. S3. During the clamping process, the detection claw (201) will be pushed in the opposite direction by the object. The pressing rod (208) will be pushed towards the pressure sensor (210) through the connecting plate (202). The pressure sensor (210) will transmit the detected pressure to the controller (11). When the controller (11) detects that the pressure value detected by the pressure sensor (210) exceeds the normal value range, it will control the hydraulic pump (401) to be turned off. When the clamping is completed, the connecting plate (202) can drive the detection claw (201) to return to its original position under the rebound action of the reinforcing spring (205). In addition, the position of the detection claw (201) is beyond the anti-slip tooth (106). When clamping the object, the surface of the object contacts the detection claw (201) first. S4. Through the shooting function of the vision sensor (5), the trajectory formed on the surface of the receiving plate (10) can be photographed in real time, thereby recording the smoothness of the trajectory and the formation time. When the trajectory is smooth, it means that the hydraulic clamp does not jam when working. If the trajectory is not smooth, it means that there is jamming. The vision sensor (5) transmits the abnormal information to the controller (11).
