Description

Technical Field

[0001] This utility model relates to the field of linear slider technology, and in particular to a slider with internal cooling that can control the temperature. Background Technology

[0002] In many fields of modern industrial production, such as precision mold processing, injection molding, and metal cutting, sliders are widely used as a key moving component. In the field of metal cutting machine tools, sliders are used to support tools or workpieces and achieve precise linear feed motion. As the requirements for machining accuracy continue to increase, more stringent standards are being put forward for the smoothness of slider movement, positioning accuracy, and thermal stability.

[0003] The existing slider lacks an efficient cooling structure, and its working stability and accuracy cannot be effectively guaranteed during long-term operation. Utility Model Content

[0004] The purpose of this invention is to provide a slider with internal cooling that can control the temperature and perform active cooling operation, ensuring that the slider still has high stability and high precision during long-term operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A temperature-controlled internally cooled slider includes a guide rail, a slider slidably mounted on the outside of the guide rail, two cooling channels inside the slider, a cooler outside the slider, and a cooling base. An inlet pipe is fixedly installed at the outlet of the cooling base, and the inlet pipe has two outlet ports, each connected to an inlet port of one of the two cooling channels. A return pipe is fixedly installed at the outlet port of each cooling channel, and the other end of the return pipe is connected to a return port of the cooling base. A delivery pump is fixedly installed in the inlet pipe, and the cooling base contains coolant.

[0007] By adopting the above technical solution, active cooling can be achieved by circulating coolant through the cooling channel, ensuring that the slider maintains high stability and high precision even during long-term operation.

[0008] Furthermore, both ends of the slider are equipped with end caps, and an oil scraper is installed on one outer surface of the end cap.

[0009] By adopting the above technical solution, the outer surface of the guide rail can be effectively scraped with oil.

[0010] Furthermore, the scraper blade is composed of an inner support steel plate and a rubber sleeve. The inner support steel plate has multiple engaging grooves along its edge, each groove being three-quarters of a circle. The rubber sleeve wraps around the outer side of the inner support steel plate, and the inner wall of the rubber sleeve has protrusions that match the engaging grooves and engage inside them. The outer surface of the inner support steel plate has multiple conical holes, and the inner wall of the rubber sleeve is integrally connected with multiple conical protrusions, which engage inside the conical holes.

[0011] By adopting the above technical solution, the connection between the rubber sleeve and the inner support steel plate can be strengthened, and it can replace the traditional glue bonding.

[0012] Furthermore, a mounting groove is provided on one outer surface of the cooling base, and a semiconductor cooling plate is fixedly installed inside the mounting groove. Multiple cooling fins are fixedly connected to one inner wall of the cooling base.

[0013] By adopting the above technical solution, the coolant inside the cooling base can be effectively cooled.

[0014] Furthermore, a mounting hole is provided on one outer surface of the cooling base, and a temperature sensor is fixedly installed inside the mounting hole. The temperature sensor is located at the liquid return port of the cooling base. A temperature control switch is fixedly installed on the upper surface of the cooling base. The temperature sensor is electrically connected to the temperature control switch, and the temperature control switch is electrically connected to the semiconductor cooling plate.

[0015] By adopting the above technical solution, effective temperature monitoring can be performed, and active temperature control can be achieved.

[0016] Furthermore, a heat sink is fixedly installed on one outer surface of the cooling base, and the heat sink is in contact with the heating surface of the semiconductor cooling plate.

[0017] By adopting the above technical solutions, the heat dissipation efficiency of the semiconductor cooling plate can be improved.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. During operation, this utility model can start the delivery pump, which circulates the coolant inside the cooling base through the inlet pipe, cooling channel, and return pipe. Since a temperature sensor is installed at the return port of the cooling base, the temperature of the coolant can be detected in real time and the temperature data is transmitted to the temperature control switch. When the set temperature value is reached, the temperature control switch energizes the semiconductor refrigeration plate, which cools the coolant inside the cooling base, thereby actively cooling the inside of the slider. This ensures that the slider remains at a constant temperature during long-term operation, improving the stability and accuracy of the slider's operation. The functionality and practicality are effectively improved.

[0020] 2. This utility model, by setting multiple locking grooves at the edge of the inner support steel plate and setting matching protrusions inside the rubber sleeve, with the protrusions locking inside the locking grooves, can effectively improve the stability and firmness of the rubber sleeve wrapping the outer side of the inner support steel plate, replacing the traditional method of glue connection, making the assembly process more convenient, and at the same time, the stability and service life are effectively improved, and the practicality is further improved.

[0027] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A type of internally cooled, temperature-controlled slider includes a guide rail 1, a slider 2 slidably mounted on the outside of the guide rail 1, two cooling channels 18 inside the slider 2, a cooler 5 outside the slider 2, the cooler 5 including a cooling base 6, an inlet pipe 10 fixedly mounted at the outlet of the cooling base 6, the inlet pipe 10 having two outlet ports, and the two outlet ports of the inlet pipe 10 respectively communicating with the inlet ports of the two cooling channels 18, and a return pipe 12 fixedly mounted at the outlet ports of the cooling channels 18. The other end of pipe 2 is connected to the return port of cooling base 6. A delivery pump 9 is fixedly installed in the pipeline of inlet pipe 10. Cooling base 6 is filled with coolant. A mounting groove is provided on one outer surface of cooling base 6, and a semiconductor cooling plate 13 is fixedly installed inside the mounting groove. Multiple cooling fins 17 are fixedly connected to the inner wall of one side of cooling base 6. A mounting hole is provided on one outer surface of cooling base 6, and a temperature sensor 11 (PT100) is fixedly installed inside the mounting hole. The temperature sensor 11 is located at the return port of cooling base 6. At the liquid port, a temperature control switch 7 is fixedly installed on the upper surface of the cooling base 6. A temperature sensor 11 is electrically connected to the temperature control switch 7, and the temperature control switch 7 is electrically connected to the semiconductor cooling plate 13. A heat sink 8 is fixedly installed on one outer surface of the cooling base 6, and the heat sink 8 is in contact with the heating surface of the semiconductor cooling plate 13. During operation, the delivery pump 9 can be started, which causes the coolant inside the cooling base 6 to circulate through the inlet pipe 10, the cooling channel 18, and the return pipe 12. Since a temperature sensor 11 is installed at the return port of the cooling base 6, the temperature of the coolant can be detected in real time, and the temperature data can be transmitted to the temperature control switch 7. When the set temperature value is reached, the temperature control switch 7 energizes the semiconductor cooling plate 13, and the semiconductor cooling plate 13 cools the coolant inside the cooling base 6, thereby actively cooling the inside of the slider 2. This ensures that the slider 2 remains at a constant temperature during long-term operation, improving the stability and accuracy of the slider 2. The functionality and practicality of the slider 2 are effectively improved.

[0029] Reference Figure 2Both ends of the slider 2 are equipped with end caps 3. A scraper 4 is mounted on the outer surface of one side of each end cap 3. The scraper 4 consists of an inner support steel plate 14 and a rubber sleeve 16. Multiple engaging grooves 15 are provided along the edge of the inner support steel plate 14. Each engaging groove 15 is three-quarters of a circle. The rubber sleeve 16 wraps around the outer surface of the inner support steel plate 14, and its inner wall has protrusions that match the engaging grooves 15 and engage within them. Multiple conical holes 19 are provided on the outer surface of the inner support steel plate 14. Multiple conical protrusions 20 are integrally connected to the inner wall of the rubber sleeve 16, and these protrusions 20 engage within the conical holes 19. Multiple engaging grooves 15 are provided along the edge of the inner support steel plate 14, and matching protrusions are provided inside the rubber sleeve 16. The protrusions engage inside the engaging grooves 15, which can effectively improve the stability and firmness of the rubber sleeve 16 wrapping around the inner support steel plate 14. At the same time, the protrusions 20 are snapped into the conical holes 19, which can further improve the stability of the connection of each structure. Furthermore, the entire scraper blade 4 adopts an integrated vulcanization process, which allows the rubber sleeve 16 to fit tightly with the inner support steel plate 14, replacing the traditional method of glue connection. The assembly process is more convenient, and the stability and service life are effectively improved, thus further enhancing its practicality.

[0030] Working principle: In use, the slider is first installed in the designated position. When the slider runs, the delivery pump 9 is started. The delivery pump 9 causes the coolant inside the cooling base 6 to circulate through the inlet pipe 10, cooling channel 18, and return pipe 12. Since a temperature sensor 11 is installed at the return port of the cooling base 6, the temperature of the coolant can be detected in real time and the temperature data is transmitted to the temperature control switch 7. When the set temperature value is reached, the temperature control switch 7 energizes the semiconductor refrigeration plate 13. With the assistance of the cooling fins 17, the semiconductor refrigeration plate 13 can effectively energize the coolant inside the cooling base 6. The coolant is used for cooling, and the low temperature of the coolant is used to actively cool the inside of the slider 2, so that the slider 2 remains at a constant temperature during long-term operation, which improves the stability and accuracy of the slider 2. During the operation of the slider 2, multiple locking grooves 15 are set at the edge of the inner support steel plate 14, and matching protrusions are set inside the rubber sleeve 16. The protrusions engage inside the locking grooves 15, which can effectively improve the stability and firmness of the rubber sleeve 16 wrapped around the inner support steel plate 14, and ensure the working stability of the scraper blade 4.
