Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to an oil pressure multiplier locking device. Background Art

[0002] The primary function of a hydraulic locking device is to provide high-precision positioning and clamping in mechanical equipment. This device is typically used in applications requiring high clamping force, such as in machine tool table clamping systems. By leveraging the pressure generated by the hydraulic system, the locking device amplifies the applied force, thereby achieving a secure clamping of the table and ensuring a smooth, vibration-free operation during the cutting process.

[0003] The performance of a hydraulic locking device depends largely on the quality and condition of the hydraulic oil. The ideal operating temperature is generally between 30°C and 50°C. If the hydraulic oil temperature is below 30°C, the viscosity of the hydraulic oil increases, resulting in poor fluid flow, slowing the action of the hydraulic locking device and increasing the clamping and release response time. If the hydraulic oil temperature is above 50°C, the viscosity decreases, making leakage more likely. Furthermore, high temperatures accelerate the oxidation process of the hydraulic oil, and the resulting oxidation products can damage the hydraulic system.

[0004] Therefore, a kind of oil pressure multiplying force locking device is badly needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an oil pressure multiplier locking device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an oil pressure multiplier locking device, comprising:

[0007] oil pipelines;

[0008] A diverter mechanism is provided on the outside of the oil pipeline;

[0009] The temperature changing mechanism is arranged on the side of the diversion mechanism and is connected with the diversion mechanism.

[0010] Preferably, the diversion mechanism includes:

[0011] a water tank, which is arranged outside the water tank and contacts the surface of the oil pipeline;

[0012] A water inlet pipe is arranged on the top of the water tank;

[0013] A thermometer is arranged inside the water inlet pipe;

[0014] A water pump is arranged inside the water inlet pipe;

[0015] A drainage pipe is provided at the water outlet end of the water inlet pipe;

[0016] A guide plate is provided at the connection end of the drainage pipe and the water inlet pipe;

[0017] The water outlet pipe is arranged at the bottom of the water tank.

[0018] Preferably, the temperature changing mechanism comprises:

[0019] A cooling chamber is provided at the cooling end of the drainage pipe;

[0020] A heat sink is arranged inside the cooling chamber;

[0021] A heating chamber is provided at the heating end of the drainage tube;

[0022] The heating wire is arranged inside the heating chamber;

[0023] The return pipe is arranged at the water outlet end of the cooling chamber and the heating chamber and is connected to the water outlet pipe.

[0024] Preferably, the guide plate is long enough to contact the inner wall of the water outlet pipe.

[0025] Preferably, the end of the guide plate that contacts the inside of the water outlet pipe is set at an angle.

[0026] Preferably, the width of the guide plate is the same as the width of the drainage tube.

[0027] Compared with the prior art, the beneficial effects of this invention are:

[0028] This utility utilizes the coordination of a diversion mechanism and a temperature-changing mechanism. When the hydraulic oil temperature in the oil pipeline is low, the guide plate is moved to the side closest to the cooling chamber, allowing water to flow from the water inlet pipe into the heating chamber. The heating wire heats the water, which then flows back through the outlet pipe to the water tank, completing the heating of the oil pipeline. When the hydraulic oil temperature in the oil pipeline is high, the guide plate is moved to the side closest to the heating chamber, allowing water to flow from the water pipe into the cooling chamber. The heat sink dissipates the heat from the water, which then flows back through the water pipe to the water tank, completing the heat dissipation of the oil pipeline. This device uses a thermometer to monitor the water temperature to heat or dissipate heat in the oil pipeline, ensuring that the hydraulic oil is at the appropriate operating temperature and protecting the oil pressure locking device.

DETAILED DESCRIPTION

[0035] To facilitate solving the problems described in the background art, this practical embodiment provides a hydraulic multiplier locking device. The technical solutions in this practical embodiment will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this practical embodiment, not all of them. Based on the embodiments in this practical embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical embodiment.

[0036] See also Figure 1-5 This embodiment provides an oil pressure multiplier locking device, comprising:

[0037] Oil pipe 10, the hydraulic oil used by the oil pressure multiplier locking device circulates through the oil pipe 10;

[0038] The diverter mechanism 20 is provided on the outside of the oil pipeline 10 and contacts the outside of the oil pipeline 10 to help heat or cool the hydraulic oil inside the oil pipeline 10;

[0039] The temperature changing mechanism 30 is provided on the side of the diverter mechanism 20 , is connected to the diverter mechanism 20 , and exchanges water with the water flow inside the diverter mechanism 20 .

[0040] Specifically, the diversion mechanism 20 includes:

[0041] The water tank 21 is arranged outside the water tank 21 and contacts the surface of the oil pipeline 10 to heat or cool the hydraulic oil inside the oil pipeline 10 according to the principle of heat conduction;

[0042] The water inlet pipe 22 is provided at the top of the water tank 21, through which the water flows out of the water tank 21 and enters the diversion mechanism 20;

[0043] The thermometer 23 is provided inside the water inlet pipe 22 to monitor the temperature of the water flowing through the water inlet pipe 22, monitor the temperature of the water flow in real time, and indirectly monitor the temperature of the hydraulic oil in the oil pipeline 10 through the temperature of the water flow, thereby assisting the staff in heating or cooling the hydraulic oil in the oil pipeline 10;

[0044] The water pump 24 is provided inside the water inlet pipe 22 to pump water out of the water tank 21 to help the water flow inside the device to circulate the temperature; the drainage pipe 25 is provided at the outlet end of the water inlet pipe 22 to help the water inlet pipe 22 to divert the water flow entering the diversion mechanism 20;

[0045] The guide plate 26 is located at the connection end of the drainage pipe 25 and the water inlet pipe 22. The connection end of the drainage pipe 25 and the water pump 24 is the overlapping portion of the drainage pipe 25 and the water inlet pipe 22. Water flows through this portion from the water inlet pipe 22 to the interior of the drainage pipe 25. The guide plate 26 controls whether the water flows into the heating end or the cooling end of the drainage pipe 25. The guide plate 26 is moved to the side close to the cooling chamber 31, and the water flows from the water inlet pipe 22 into the heating chamber 33, where the heating wire 34 heats the water. When the temperature of the hydraulic oil in the oil pipeline 10 is high, the guide plate 26 is moved to the side close to the heating chamber 33, and the water flows from the drainage pipe 25 into the cooling chamber 31. The staff can determine the temperature of the hydraulic oil using the thermometer 23 and adjust the guide plate 26 based on the temperature of the hydraulic oil, thereby changing the device to heat or cool the hydraulic oil.

[0046] The water outlet pipe 27 is provided at the bottom of the water tank 21 , and the water flow after heating or cooling returns to the water tank 21 through the water outlet pipe 27 .

[0047] Specifically, the temperature changing mechanism 30 includes:

[0048] A cooling chamber 31 is provided at the cooling end of the drainage pipe 25 and cools the water flow;

[0049] The heat sink 32 is provided inside the cooling chamber 31 and transfers the heat in the water flow to the outside of the cooling chamber 31;

[0050] A heating chamber 33 is provided at the heating end of the drainage pipe 25 and heats the water flow;

[0051] The heating wire 34 is disposed inside the heating chamber 33 ; the heating wire 34 heats the water flow, and the water flow further carries the heat to the water tank 21 ;

[0052] The return pipe 35 is provided at the water outlet end of the cooling chamber 31 and the heating chamber 33 and is connected to the water outlet pipe 27 to guide the water flow that has been cooled in the cooling chamber 31 or heated in the heating chamber 33 into the water outlet pipe 27 to complete the water circulation.

[0053] Specifically, the guide plate 26 is long enough to contact the inner wall of the water outlet pipe 27 , ensuring that the guide plate 26 can lean against the inside of the water outlet pipe 27 and guide all the water flow into the cooling chamber 31 or the heating chamber 33 .

[0054] Specifically, an angle is set at the end of the guide plate 26 that contacts the inside of the water outlet pipe 27. The angle is to help the guide plate 26 further fit the inner wall of the water outlet pipe 27 to ensure that when the guide plate 26 is moved to one end of the cooling bin 31, the water flow will not pass through the guide plate 26 into the heating bin 33, or when the guide plate 26 is moved to one end of the heating bin 33, the water flow will not pass through the guide plate 26 into the cooling bin 31.

[0055] Specifically, the width of the guide plate 26 is the same as the width of the drainage tube 25, reducing the gap between the guide plate 26 and the drainage plate, ensuring that when the guide plate 26 is moved to one end of the cooling bin 31, the water flow will not pass through the guide plate 26 into the heating bin 33, or when the guide plate 26 is moved to one end of the heating bin 33, the water flow will not pass through the guide plate 26 into the cooling bin 31, thereby improving the airtightness of the guide plate 26.

[0056] When using:

[0057] Assume that the ideal working temperature of the hydraulic oil used in the oil pressure multiplier locking device is 30℃-50℃.

[0058] When the thermometer 23 detects that the working temperature of the hydraulic oil is lower than 30°C through the temperature of the water circulating inside the device, the staff will move the guide plate 26 to the side close to the cooling chamber 31, and the water pump 24 will pump water from the water tank 21 to the diversion mechanism 20. The staff will turn on the heating wire 34, and the water will enter the drainage pipe 25 through the water inlet pipe 22 of the diversion mechanism 20. The water will flow through the drainage pipe 25 and enter the heating chamber 33. The heating wire 34 in the heating chamber 33 will heat the water. The heated water will flow through the return pipe 35 and return to the water tank 21 through the water outlet pipe 27, completing the heating of the oil pipeline 10. The above process is repeated until the staff detects through the thermometer 23 that the temperature of the water in the dynamic water tank 21 that has completed heating the oil pipeline 10 exceeds 30°C, and then the oil pipeline 10 will be cooled.

[0059] When the staff detects through the thermometer 23 that the temperature of the water pumped out of the water tank 21 by the water pump 24 exceeds 50°C, the staff will move the guide plate 26 to the side close to the heating chamber 33, and the water pump 24 will pump the water from the water tank 21 to the diversion mechanism 20. The staff will turn off the heating wire 34, and the water will enter the drainage pipe 25 through the water inlet pipe 22 of the diversion mechanism 20. The water will flow through the drainage pipe 25 and enter the cooling chamber 31 of the temperature changing mechanism 30. The heat sink 32 in the cooling chamber 31 dissipates heat from the water. The water that has completed heat dissipation in the heat dissipation chamber flows through the return pipe 35 and returns to the water tank 21 through the water outlet pipe 27, completing the heat dissipation of the oil pipeline 10. The above process is repeated until the staff detects through the thermometer 23 that the temperature of the water in the dynamic water tank 21 that has completed heating the oil pipeline 10 is lower than 30°C, and then the oil pipeline 10 is heated.

[0060] This device monitors the temperature and controls the temperature of the hydraulic oil in the oil pipeline 10 between the ideal working temperatures, thereby protecting the oil pressure multiplier locking device and preventing the oil pressure multiplier locking device from being damaged due to excessively high or low temperature.
