Description

Technical Field

[0001] This utility model relates to the field of thread grinding machine bed technology, and in particular to a high-precision thread grinding machine bed made of mineral casting. Background Technology

[0002] A thread grinding machine is a machine tool that uses a shaped grinding wheel as an abrasive to process precision threads. The entire machine tool is composed of numerous parts, including the thread grinding machine bed. The grinding machine bed is used to support the thread processing mechanism and is an effective guarantee for the normal operation of the entire thread grinding machine.

[0003] The existing grinding machine bed lacks an efficient heat dissipation structure. During long-term processing, the heat generated by the sliding parts is transferred to the grinding machine bed, which can lead to uneven heating of the bed and deformation, thus affecting the processing accuracy and requiring improvement in practicality. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision thread grinding machine bed for mineral casting that can perform efficient heat dissipation during operation, avoiding uneven temperature distribution and deformation of the bed, and is highly practical.

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

[0006] A high-precision thread grinding machine bed for mineral casting includes a bed body. Two rails are integrally connected to the upper surface of the bed body. Cooling holes are provided on the inner side of the rails, and cooling pipes pass through the interior of the cooling holes. A first housing is fixedly installed on one outer surface of the bed body. A refrigeration tank is fixedly installed on the inner wall of the first housing. The two ends of the cooling pipe are respectively fixedly connected to the upper and lower end faces of the refrigeration tank. A delivery pump is fixedly installed in the pipeline of the cooling pipe.

[0007] By adopting the above technical solution, the main body of the bed can be actively cooled.

[0008] Furthermore, a mounting groove is provided on each of the symmetrical outer surfaces of the refrigeration tank, and a refrigeration rack is fixedly installed inside the mounting groove. Both the refrigeration tank and the cooling pipe are filled with coolant.

[0009] By adopting the above technical solution, the refrigeration rack can be used for temperature transfer.

[0010] Furthermore, a semiconductor refrigeration plate is respectively installed on the outer surfaces of the two symmetrical sides of the refrigeration tank, and the refrigeration rack is attached to the refrigeration surface of the semiconductor refrigeration plate.

[0011] By adopting the above technical solution, a semiconductor refrigeration plate can be used to cool the coolant inside the refrigeration tank.

[0012] Furthermore, multiple deformation detection mechanisms are installed on the inner side of the bed body. Each deformation detection mechanism includes a photoelectric switch one and a photoelectric switch two, and a thin metal tube is installed between the photoelectric switch one and the photoelectric switch two.

[0013] By adopting the above technical solution, the deformation detection mechanism can be used to detect the deformation of the bed in real time.

[0014] Furthermore, a second housing is fixedly installed on the side surface of the bed body. Multiple indicator lights and control relays are fixedly installed on the inner wall of the second housing. The photoelectric switch is electrically connected to the control terminal of the control relay. The number of indicator lights is the same as the number of control relays, and the indicator lights are electrically connected to the control relays.

[0015] By adopting the above technical solution, the working circuit of the indicator light will be effectively closed when deformation occurs.

[0016] Furthermore, a buzzer is fixedly installed on the inner wall of the second housing, and multiple control relays are electrically connected to the buzzer.

[0017] By adopting the above technical solution, a buzzer can sound an alarm when deformation occurs.

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

[0019] 1. In operation, the moving mechanism of the grinding machine slides on the track, and then the delivery pump is started. The delivery pump causes the coolant inside the refrigeration tank to circulate inside the cooling pipe. Since the cooling pipe runs through the inside of the track, it can effectively cool and dissipate heat from the track, avoiding uneven heating and deformation of the track due to long-term operation. The overall functionality and practicality are effectively improved.

[0020] 2. This utility model utilizes a deformation detection mechanism installed at a vulnerable location to detect deformation of the machine bed body in real time. During detection, photoelectric switch one generates light, which passes through a thin metal tube and illuminates photoelectric switch two. Once photoelectric switch two detects the light, it does not send an electrical signal to the control relay. Due to the small diameter and susceptibility of the thin metal tube, deformation at the installation location will cause the tube to deform, thus blocking the light generated by photoelectric switch one. At this time, photoelectric switch two sends an electrical signal to the control terminal of the control relay, causing the corresponding control relay to close the corresponding indicator light circuit and buzzer circuit. The resulting alarm signal promptly alerts the operator to deformation of the machine bed body. The corresponding indicator light then indicates the location of the deformation. This structure enables real-time deformation detection of the grinding machine bed, further improving its functionality and practicality, and playing a positive role in improving machining accuracy.

Detailed Implementation

[0026] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 , Figure 4A high-precision thread grinding machine bed for mineral casting includes a bed body 1. Two rails 2 are integrally connected to the upper surface of the bed body 1. Cooling holes are provided on the inner side of the rails 2, and cooling pipes 3 pass through the interior of the cooling holes. A first housing 4 is fixedly installed on one outer surface of the bed body 1. A refrigeration tank 5 is fixedly installed on the inner wall of the first housing 4. The two ends of the cooling pipes 3 are respectively fixedly connected to the upper and lower end faces of the refrigeration tank 5. A delivery pump 6 is fixedly installed in the pipeline of the cooling pipes 3. A mounting groove is provided on each of the symmetrical outer surfaces of the refrigeration tank 5, and a refrigeration rack 15 is fixedly installed inside the mounting groove. Both the refrigeration tank 5 and the cooling pipes 3 are filled with coolant. A cooling rack 15 is installed on each of the symmetrical outer surfaces of the refrigeration tank 5. A semiconductor cooling plate 14 and a cooling rack 15 are attached to the cooling surface of the semiconductor cooling plate 14. During operation, the moving mechanism of the grinding machine slides on the track 2, and then the delivery pump 6 is started. The delivery pump 6 causes the coolant inside the cooling tank 5 to circulate inside the cooling pipe 3. Since the cooling pipe 3 runs through the inside of the track 2, the cooling rack 15 and the semiconductor cooling plate 14 are installed on the symmetrical two sides of the cooling tank 5, respectively. The semiconductor cooling plate 14 can be used to reduce the temperature of the cooling rack 15, thereby reducing the temperature of the coolant inside the cooling tank 5. Therefore, the track 2 can be effectively cooled and dissipated, avoiding uneven heating and deformation of the track 2 due to long-term operation. The overall functionality and practicality are effectively improved.

[0028] Reference Figure 1 , Figure 2 , Figure 3Multiple deformation detection mechanisms 16 are installed on the inner side of the bed body 1. Each deformation detection mechanism 16 includes a photoelectric switch 1 7 and a photoelectric switch 2 8. A thin metal tube 9 is installed between the photoelectric switch 1 7 and the photoelectric switch 2 8. A second housing 10 is fixedly installed on the side surface of the bed body 1. Multiple indicator lights 11 and control relays 12 are fixedly installed on the inner wall of the second housing 10. The photoelectric switch 2 8 is electrically connected to the control terminal of the control relay 12. The number of indicator lights 11 is the same as the number of control relays 12, and the indicator lights 11 are electrically connected to the control relays 12. A buzzer 13 is fixedly installed on the inner wall of the second housing 10, and the multiple control relays 12 are all electrically connected to the buzzer 13. The deformation detection mechanism 16 installed at the easily deformable parts can be used to detect whether the easily deformable parts of the bed body 1 are deformed in real time. During detection, the photoelectric switch 1 7 produces a sound. The light beam passes through the thin metal tube 9 and shines on the photoelectric switch 8. Upon detecting the light, the photoelectric switch 8 will not send an electrical signal to the control relay 12. Because the thin metal tube 9 has a small diameter and is easily deformed, deformation at the installation location will cause the thin metal tube 9 to deform, thus blocking the light generated by the photoelectric switch 7. At this time, the photoelectric switch 8 sends an electrical signal to the control terminal of the control relay 12, causing the corresponding control relay 12 to close the working circuit of the corresponding indicator light 11 and the working circuit of the buzzer 13. The alarm signal generated at this time can promptly remind the operator that the bed body 1 has deformed. Then, the corresponding deformation location can be found through the corresponding indicator light 11. This structure enables the grinding machine bed to perform deformation detection operations in real time, further improving functionality and practicality, and playing a positive role in improving machining accuracy.

[0029] Working principle: During use, the bed body 1 can support the movement of the grinding machine's machining mechanism. At this time, the movable mechanism slides inside the track 2. Then, the delivery pump 6 is started, which causes the coolant inside the refrigeration tank 5 to circulate inside the cooling pipe 3. Since the cooling pipe 3 runs through the inside of the track 2, the refrigeration frame 15 and the semiconductor refrigeration plate 14 are respectively installed on the symmetrical two sides of the refrigeration tank 5. The semiconductor refrigeration plate 14 can be used to reduce the temperature of the refrigeration frame 15, thereby reducing the temperature of the coolant inside the refrigeration tank 5. Therefore, the track 2 can be effectively cooled and dissipated. During the operation of the grinding machine, the deformation detection mechanism 16 installed at the deformable part is used to detect whether the deformable part of the bed body 1 is deformed in real time. During detection, the photoelectric switch 7 generates... Light passes through the thin metal tube 9 and shines on the photoelectric switch 8. After detecting the light, the photoelectric switch 8 will not send an electrical signal to the control relay 12. Because the thin metal tube 9 has a small diameter and is easily deformed, if the installation part deforms, it will cause the thin metal tube 9 to deform, thus blocking the light generated by the photoelectric switch 7. At this time, the photoelectric switch 8 sends an electrical signal to the control terminal of the control relay 12. The corresponding control relay 12 closes the working circuit of the corresponding indicator light 11 and the working circuit of the buzzer 13. The alarm signal generated at this time can promptly remind the operator that the bed body 1 has deformed. Then, the corresponding deformation position can be found through the corresponding indicator light 11. This structure enables the grinding machine bed to perform deformation detection operations in real time.
