Description

Technical Field

[0001] This utility model belongs to the field of pneumatic clamp insulation technology, and specifically relates to a pneumatic clamp water circulation device that is easy to adjust the temperature. Background Technology

[0002] In the field of material mechanical property testing, especially in tensile property testing, pneumatic clamps play a key role. However, the influence of high and low temperature changes on the cylinder seriously restricts the accuracy and reliability of the test.

[0003] In high-temperature environments, cylinders face numerous problems. First, the seals inside the cylinder are easily affected by high temperatures, causing them to age and deform, resulting in a significant reduction in sealing performance. This makes the clamping force of pneumatic clamps unstable, making it impossible to firmly fix materials in tensile tests and affecting test results. Second, high temperatures can alter the properties of the lubricating oil inside the cylinder, reducing its lubrication effect and increasing friction between moving parts. This not only reduces the working efficiency of the cylinder but also accelerates its wear and shortens its service life.

[0004] In low-temperature environments, the situation is equally concerning. The lubricating oil inside the cylinder becomes viscous, greatly increasing the cylinder's resistance to movement and causing it to move slowly or even fail to function properly. This makes it impossible for the pneumatic clamp to operate in a timely and accurate manner during tensile testing, affecting the test progress. At the same time, low temperatures may make the cylinder material brittle, increasing the risk of cracks and other damage. In short, the adverse effects of high and low temperature changes on the cylinder seriously hinder the smooth progress of tensile testing in the mechanical property testing of materials, and this issue urgently needs to be addressed.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A pneumatic clamp water circulation device for easy temperature adjustment includes a cylinder, a heat exchange mechanism is sleeved on the outer surface of the cylinder, a temperature adjustment mechanism is fixedly installed on one side of the heat exchange mechanism, and the temperature adjustment mechanism and the heat exchange mechanism are internally connected.

[0008] The heat exchange mechanism includes a sleeve, which is fixedly installed on the outer surface of the cylinder. A cavity is opened inside the sleeve, and a heat exchange coil is fixedly installed on the inner side of the cavity. A temperature sensor is fixedly connected to the middle of one side of the sleeve, and the detection end of the temperature sensor is located inside the sleeve. The temperature adjustment mechanism is fixedly installed on the outer side of the sleeve.

[0009] As a preferred technical solution, the temperature control mechanism includes a water pump, a connecting component, a cooling component, and a heating component. The water pump is fixedly installed on the upper end of the sleeve on the side away from the temperature sensor. The connecting component is located at the output and input ends of the cooling and heating components. The connecting component at the bottom is connected to the heat exchange coil, and the connecting component at the top is connected to the output end of the water pump. The water pump is fixedly installed on the upper end of the sleeve on the side away from the temperature sensor, and the input end of the water pump is connected to the output end of the heat exchange coil.

[0010] As a preferred technical solution, the connecting assembly includes a connecting pipe, which is fixedly installed at the output end of the water pump and the lower end of the sleeve away from the temperature sensor. The output end of the lower connecting pipe is connected to the heat exchange coil. A tee pipe is fixedly installed at both the output end of the upper connecting pipe and the input end of the lower connecting pipe. A solenoid valve is fixedly connected to both ends of the tee pipe. A connecting pipe is fixedly installed at the outer end of the solenoid valve. The connecting pipe is connected to the refrigeration component and the heating component respectively.

[0011] As a preferred technical solution, the refrigeration assembly includes a refrigeration tank, which is fixedly installed between the inner sides of two longitudinally arranged connecting pipes located on one side. The connecting pipes at the top and bottom of the refrigeration tank are connected to the interior of the refrigeration tank. A semiconductor cooler is fixedly installed on the outside of the refrigeration tank, and the cooling end of the semiconductor cooler is located inside the refrigeration tank.

[0012] As a preferred technical solution, the heating component includes a heating tank, which is fixedly installed between the inner sides of two other longitudinally arranged connecting pipes. An electric heating tube is fixedly installed inside the cooling tank, and the electric heating tube is coiled inside the heating tank.

[0013] As a preferred technical solution, a box is fixedly installed between the inner sides of the refrigeration tank and the heating tank. A DSP controller is fixedly installed inside the box, and temperature sensors are also fixedly connected to both sides of the box.

[0015] In summary, the present invention has the following main advantages:

[0016] First, this device is equipped with a heat exchange mechanism. In actual use, hot and cold water can be supplied as needed through the temperature control mechanism. The temperature sensor detects the temperature inside the cavity. When the temperature is too low, the DSP controller controls the heating component to prepare hot water, which is then pumped into the sleeve for preheating. When the temperature is too high, the cooling component is activated to prepare cold water. The cold water circulates in the heat exchange coil to cool down. The cooling and heating components are set independently, which can respond quickly when the cylinder temperature changes rapidly and accurately control the temperature. This allows the cylinder to heat up at low temperatures and cool down at high temperatures, providing a reliable guarantee for the stable operation of the cylinder and ensuring more accurate and rapid overall temperature control.

[0017] Secondly, the temperature control mechanism of this device performs excellently in temperature regulation. During preheating, the solenoid valve on the cooling component side is closed, and the solenoid valve on the heating component side is opened, allowing the heating tank to connect with the heat exchange coil. The heat flow circulates in the heat exchange coil to raise the temperature. When cooling is required, the opposite is true: the solenoid valve on the heating component is closed, and the solenoid valve on the cooling component is opened, allowing the cold flow to circulate in the heat exchange coil to lower the temperature. This can quickly regulate the temperature of the medium inside the cavity, providing good insulation for the cylinder, ensuring that the cylinder temperature is within the ideal range, reducing the adverse effects of hot and cold temperatures, and improving the cylinder's working efficiency and service life.

The placement of the temperature sensor 24 can... The temperature inside the sleeve 21 is monitored in real time to provide a basis for precise control. The temperature adjustment mechanism 3 is internally connected to the heat exchange mechanism 2 and can adjust the temperature according to actual needs. When heating is required, the temperature adjustment mechanism 3 can work with the heat exchange mechanism 2 to provide hot water circulation to the cylinder 1 to quickly increase the temperature of the cylinder 1. When the temperature of the cylinder 1 is too high, it can switch to cold water circulation to cool down. The overall design improves the temperature regulation efficiency and accuracy of the pneumatic clamp, ensures that the cylinder 1 can maintain a stable temperature under different working environments, extends the service life of the cylinder 1, and improves the working performance and reliability of the pneumatic clamp.

[0026] refer to Figures 1-4 The temperature control mechanism 3 includes a water pump 31, a connecting assembly 32, a cooling assembly 33, and a heating assembly 34. The water pump 31 is fixedly installed on the upper end of the sleeve 21 on the side away from the temperature sensor 24. The connecting assembly 32 is located at the output and input ends of the cooling assembly 33 and the heating assembly 34. The connecting assembly 32 at the bottom is connected to the heat exchange coil 23, and the connecting assembly 32 at the top is connected to the output end of the water pump 31. The water pump 31 is fixedly installed on the upper end of the sleeve 21 on the side away from the temperature sensor 24, and the input end of the water pump 31 is connected to the output end of the heat exchange coil 23. The water pump 31 in the temperature control mechanism 3 provides power to the entire system, ensuring that water circulates in the device. Component 32 cleverly connects the cooling component 33 and the heating component 34 to the heat exchange coil 23, achieving flexible temperature regulation. When heating is required, the heating component 34 delivers hot water to the heat exchange coil 23 through the connecting component 32. With the help of the water pump 31, the hot water circulates and quickly heats up the cylinder 1. When cooling is required, the cooling component 33 delivers cold water to the heat exchange coil 23 through the connecting component 32. Similarly, the cold water circulates under the action of the water pump 31, effectively reducing the temperature of the cylinder 1. This design can quickly switch between hot and cold water circulation according to actual needs, accurately control the temperature of the cylinder 1, improve the adaptability and working efficiency of the pneumatic clamp, and extend the service life of the equipment.

[0027] refer to Figure 2-4 The connecting assembly 32 includes a connecting pipe 321, which is fixedly installed at the output end of the water pump 31 and the lower end of the sleeve 21 away from the temperature sensor 24. The output end of the lower connecting pipe 321 is connected to the heat exchange coil 23. A three-way pipe 322 is fixedly installed at both the output end of the upper connecting pipe 321 and the input end of the lower connecting pipe 321.

The connecting pipe 324 is connected to the refrigeration assembly 33 and the heating assembly 34 respectively. The connecting pipe 321 in the connecting assembly 32 plays a key connecting role, effectively connecting the water pump 31 with the heat exchange coil 23 and the three-way pipe 322. The setting of the three-way pipe 322 is extremely ingenious. Ingeniously, the solenoid valves 323 at both ends enable precise switching of water flow paths according to different temperature requirements. When heating is needed, the solenoid valves 323 are controlled to open the connecting pipe 324 connected to the heating component 34, allowing hot water to flow smoothly from the heating component 34 through the connecting pipe 324, the three-way pipe 322, and the connecting pipe 321 into the heat exchange coil 23, providing the heat required for heating the cylinder 1. When cooling is needed, the solenoid valves 323 are switched to activate the connecting pipe 324 connected to the cooling component 33, allowing cold water to enter the heat exchange coil 23 through the corresponding path for cooling. This design makes the temperature regulation of the entire system more flexible and efficient, enabling rapid response to different temperature changes and greatly improving the practicality and reliability of the pneumatic clamp water circulation device.

[0028] refer to Figure 3-4The refrigeration assembly 33 includes a refrigeration tank 331, which is fixedly installed between the inner sides of two longitudinally arranged connecting pipes 324 located on one side. The connecting pipes 324 at the top and bottom of the refrigeration tank 331 are connected to the interior of the refrigeration tank 331. A semiconductor cooler 332 is fixedly installed on the outer side of the refrigeration tank 331, with its cooling end located inside the refrigeration tank 331. The heating assembly 34 includes a heating tank 341, which is fixedly installed between the inner sides of two other longitudinally arranged connecting pipes 324. An electric heating tube 342 is fixedly installed inside the refrigeration tank 331, and the electric heating tube 342 is coiled inside the heating tank 341. The refrigeration tank 331 in the refrigeration assembly 33 is heated by the external semiconductor cooler 332. The cooling end of the semiconductor cooler 332 is located inside the cooling tank 331, which can efficiently produce cold water. When cooling is required, the cold water can enter the heat exchange coil 23 through the connecting pipe 324, the three-way pipe 322 and the connecting pipe 321 to quickly cool down the cylinder 1. The heating component 34 has a coiled electric heating tube 342 inside the heating tank 341, which can quickly and effectively heat the water in the tank to produce hot water. When heating is required, the hot water flows into the heat exchange coil 23 through the corresponding pipe to heat up the cylinder 1. This independently set cooling and heating component 34 can respond quickly according to actual needs, accurately control the temperature of the cylinder 1, improve the temperature regulation capability and working efficiency of the pneumatic clamp water circulation device, and provide stable temperature conditions for the cylinder 1 under different working environments.

[0029] refer to Figure 4A housing 343 is fixedly installed between the inner sides of the cooling tank 331 and the heating tank 341. A DSP controller is fixedly installed inside the housing 343. Temperature sensors 24 are also fixedly connected to both sides of the housing 343. The detection ends of the temperature sensors 24 are respectively located inside the cooling tank 331 and the heating tank 341. Support columns 333 are fixedly installed at the bottom of both the cooling tank 331 and the heating tank 341. A mounting plate 334 is fixedly installed at the bottom of the support column 333. Mounting holes 335 are evenly spaced on the top of the mounting plate 334. The mounting holes 335 are countersunk holes. The DSP controller is installed inside the housing 343 between the cooling tank 331 and the heating tank 341. It can precisely control the cooling and heating processes, and adjust the operating status of the cooling component 33 and the heating component 34 in a timely manner based on the data fed back by the temperature sensor 24, ensuring that the cylinder 1 is always within a suitable temperature range. The temperature sensors 24 on both sides inside the housing 343 detect the temperature inside the cooling tank 331 and the heating tank 341 respectively, providing an accurate basis for precise control. The design of the support column 333 and the mounting plate 334 makes the entire device more stable. The countersunk hole on the top of the mounting plate 334 not only makes the installation more beautiful and neat, but also ensures a firm and reliable connection. This design improves the stability, reliability and temperature control accuracy of the water circulation device, providing a strong guarantee for the normal operation of the pneumatic clamp.

[0030] Operating principle and advantages: By setting up the heat exchange mechanism 2, this device can supply hot and cold water according to specific needs during actual use, with the help of the temperature control mechanism 3. During use, the temperature sensor 24 can detect the temperature inside the cavity 22 in real time. When the temperature inside the cavity 22 is too low, the DSP controller plays a key role in controlling the heating component 34 to efficiently produce hot water. Subsequently, the hot water is pumped into the sleeve 21 for preheating by the powerful pump 31. If the temperature suddenly becomes too high, the cooling component 33 on the other side can be quickly started to produce cold water. At this time, the circulation changes from hot water to cold water, and the cold water circulates in the cavity. The heat exchange coil 23 in cavity 22 circulates internally, thereby assisting in cooling the medium inside cavity 22. It can be seen that during the overall application of this device, it can perform hot and cold water circulation for heat dissipation or heating in real time according to the specific temperature conditions. This allows cylinder 1 to heat up quickly in low-temperature environments and cool down effectively in high-temperature environments. Overall, it can quickly regulate the temperature of cylinder 1. Furthermore, the cooling component 33 and the heating component 34 are set independently. This design allows for a rapid response when rapid temperature changes occur during the application of cylinder 1. The overall temperature control is more accurate and rapid, providing a reliable guarantee for the stable operation of cylinder 1.

[0031] By setting the temperature control mechanism 3, when the device is in use and temperature regulation is required, if preheating is needed, the solenoid valve 323 on the cooling component 33 side of the three-way pipe 322 can be closed, and the solenoid valve 323 on the heating component 34 side of the three-way pipe 322 can be opened. In this way, the heating tank 341 and the heat exchange coil 23 are connected, while the connection of the cooling component 33 is cut off. Then, the water pump 31 is started, and the heat flow can flow smoothly inside the heat exchange coil 23 to raise the temperature. If cooling is needed, the solenoid valve 323 on the heating component 34 side can be closed and the cooling component 33 can be opened. The solenoid valve 323 on one side allows the connecting pipe 324, connecting pipe 321, and refrigeration tank 331 to connect with the heat exchange coil 23 inside the cavity 22. By starting the water pump 31, cold air can circulate inside the heat exchange coil 23, which can efficiently cool the medium inside the cavity 22. It can be seen that the device as a whole can quickly regulate the temperature of the medium inside the cavity 22, thereby providing a good heat preservation effect for the cylinder 1 as a whole, ensuring that the temperature of the cylinder 1 is within the ideal range to the greatest extent, effectively reducing the adverse effects of hot and cold temperatures on the cylinder 1, and improving the working efficiency and service life of the cylinder 1.
