Description

Technical Field

[0001] This invention belongs to the field of turntables, specifically relating to a cam-type roller turntable structure. Background Technology

[0002] A rotary table is the worktable of a machine tool. It can be rotated to any position and fixed in that position. Rotary tables are mainly divided into two categories: cam roller type and worm gear type. Compared with worm gear type rotary tables, cam roller type rotary tables have advantages such as high rotational accuracy, high processing efficiency, high rigidity, low heat generation, and long service life, and are therefore widely used.

[0003] Existing cam-type roller turntable structures have some problems during use: First, although cam-type roller turntables generate less heat than worm gear turntables, frictional heat is still generated during roller operation. When this structure operates for a long time, the frictional heat of the rollers will be conducted to the cam surface, causing the cam surface to be too tightly pressed against the roller surface, affecting the transmission effect; Second, the frictional heat dissipates inside the structure, causing the turntable to heat up, which in turn changes the temperature of the material to be processed, reducing the processing accuracy of the material. Therefore, a cam-type roller turntable structure is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a cam-type roller turntable structure.

[0010] The advantages of this invention are: This invention provides a cam-type roller turntable structure.

Therefore, they should not be construed as limitations on this invention.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0025] To address the issues that arise in existing turntable structures, the rollers generate frictional heat during operation. Over prolonged operation, this frictional heat is conducted to the cam surface, causing excessive contact between the cam and roller surfaces, thus affecting transmission efficiency. Additionally, the existing turntable structure's internal temperature rise affects the temperature of the processed materials, leading to a decrease in processing accuracy.

[0026] This embodiment provides a method such as Figures 1 to 8 The cam-type roller turntable structure shown includes an outer shell 1, a cam 7, a turntable body 12, and a turntable bearing 15. Support legs 2 are fixedly connected to the four corners of the bottom of the outer shell 1. Small fans 3 are fixedly connected to both the left and right sides of the outer shell 1 to enhance airflow inside the outer shell 1 and cool the device. A motor mount 4 and a limit seat 5 are fixedly connected inside the outer shell 1. A drive motor 6 is fixedly connected to the top of the motor mount 4. The main shaft of the drive motor 6 is fixedly connected to the left end of the cam 7, and the limit seat 5 is rotatably connected to the right end of the cam 7. The drive motor 6 can drive... Cam 7 rotates. A fixed base 8 is fixedly connected to the bottom inner side of the outer casing 1. A connecting bearing 9 is fixedly connected to the outer side of the fixed base 8. An air intake 10 is provided at the bottom of the outer casing 1. A screen plate 11 is fixedly connected to the bottom of the outer casing 1. A turntable body 12 is rotatably connected to the top of the outer casing 1. A connecting pipe 13 is fixedly connected to the outer side of the turntable body 12. A sealing plate 14 is fixedly connected to the inner side of the connecting pipe 13. A turntable bearing 15 is fixedly connected to the outer side of the connecting pipe 13. A roller 16 is rotatably connected to the outer side of the turntable bearing 15. The roller 16... When cam 7 engages, its rotation drives roller 16 to rotate, simultaneously causing turntable bearing 15 to rotate. Turntable bearing 15, through connecting pipe 13, drives turntable body 12 and sealing plate 14 to rotate synchronously, thus causing sealing plate 14 to rotate the material to be processed on it. Fan 17 is fixedly connected to the inside of connecting pipe 13. Turntable body 12 has a first cooling groove 18 inside, and connecting pipe 13 has a ventilation groove 19, a first air outlet 20, and a second air outlet 21 inside. Turntable bearing 15 has a second cooling groove inside. 22; This cam-type roller turntable structure can cool the interior of the outer shell 1, and can also provide targeted cooling for heat-prone parts such as the cam 7, turntable body 12, turntable bearing 15, and roller 16. This can greatly reduce the temperature variation during long-term operation of the device, prevent the surface of the cam 7 from being too tightly attached to the surface of the roller 16, ensure the transmission effect, and prevent frictional heat from escaping into the device and causing the turntable body 12 to heat up. This also prevents the temperature of the material to be processed from changing, ensuring the processing accuracy of the material.

[0027] Furthermore, such as Figures 5-8As shown, the lower half of the outer side of the connecting pipe 13 is fixedly connected to the inner side of the connecting bearing 9. The first cooling groove 18 is connected to the first air outlet 20, the top of the ventilation groove 19 is connected to the first air outlet 20, the bottom of the ventilation groove 19 is connected to the second air outlet 21, and the second air outlet 21 is connected to the second cooling groove 22. The fan 17 will rotate synchronously with the connecting pipe 13, and the exhaust pipe at the top of the fan 17 can exhaust air. Since the sealing plate 14 seals the top of the connecting pipe 13, the fan 17 will... The bottom is sealed, so air enters the ventilation slot 19 and the second cooling slot 22 through the second air inlet 21 of the connecting pipe 13. The air entering the ventilation slot 19 enters the first cooling slot 18 through the first air inlet 20, and then is discharged from the inside of the turntable body 12 to the material processing workshop, which can remove the heat of the turntable body 12. The air entering the second cooling slot 22 is directly discharged from the turntable bearing 15 to the inside of the outer shell 1, and is discharged from the outer shell 1 by the small fan 3, which can remove the heat of the cam 7, the turntable bearing 15 and the roller 16.

[0028] Furthermore, such as Figure 2 As shown, the outer shell 1 is a rectangular shell with a circular rotating groove on the top. The support leg 2 is composed of four rectangular shafts. There are two small fans 3. The main shaft of the drive motor 6 is horizontal to the right. The cam 7 rotates and connects to the roller 16. The fixed seat 8 is a ring structure.

[0029] Furthermore, such as Figure 3 As shown, the air intake 10 is a cylindrical through groove, the sieve plate 11 is a circular plate, the turntable body 12 and the turntable bearing 15 are both disc structures, the connecting pipe 13 is a vertically distributed circular pipe structure, the sealing plate 14 is a circular plate, and there are multiple rollers 16.

[0030] Furthermore, such as Figure 6 and Figure 7 As shown, there are six of each of the following: first cooling trough 18, ventilation trough 19, first air outlet 20, second air outlet 21, and second cooling trough 22. The first cooling trough 18 and the second cooling trough 22 are all horizontally distributed cylindrical troughs, and the ventilation trough 19 are all vertically distributed cylindrical troughs.

[0031] Work process:

[0032] Before use, the power supply should be turned on. The small fan 3, drive motor 6, and fan 17 of this device are all electrical appliances. Each of the small fan 3, drive motor 6, and fan 17 has a switch, and the switches for the small fan 3, drive motor 6, and fan 17 are all located outside the outer casing 1, allowing manual control of the small fan 3, drive motor 6, and fan 17. This is existing technology. During use, first start the drive motor 6 on the top of the motor base 4. The drive motor 6 drives the cam 7 to rotate. The limit seat 5 stabilizes the rotation of the cam 7, which drives the roller 16 to rotate, simultaneously causing the turntable bearing 15 to rotate. The turntable bearing 15 is connected to the connecting pipe 1. 3. The turntable body 12 and the sealing plate 14 rotate synchronously, which allows the sealing plate 14 to rotate the material to be processed on it. The connecting bearing 9 inside the fixed seat 8 allows the connecting pipe 13 to rotate smoothly and stably, thus ensuring the stable operation of the turntable body 12. Then, the small fans 3 on the left and right sides of the outer shell 1 and the fan 17 inside the connecting pipe 13 are started. The small fans 3 can enhance the air circulation inside the outer shell 1 to cool the device. The exhaust pipe at the bottom of the fan 17 is in contact with the air inlet 10 of the outer shell 1, which can draw in the air filtered by the sieve plate 11. The fan 17 will follow the connecting pipe The components 13 rotate synchronously, and the exhaust pipe at the top of the fan 17 can exhaust air. Since the sealing plate 14 seals the top of the connecting pipe 13 and the fan 17 seals the bottom of the connecting pipe 13, the air enters the ventilation slot 19 and the second cooling slot 22 through the second air inlet 21 of the connecting pipe 13. The air entering the ventilation slot 19 enters the first cooling slot 18 through the first air inlet 20, and then is discharged from the inside of the turntable body 12 to the material processing workshop, which can remove the heat of the turntable body 12. The air entering the second cooling slot 22 is directly discharged from the turntable bearing 15 to the inside of the outer shell 1, and is then blown by the small fan. Fan 3 exhausts heat from the outer casing 1, carrying away heat from the cam 7, turntable bearing 15, and roller 16. This device can cool the interior of the outer casing 1 and also provide targeted cooling for heat-prone parts such as the cam 7, turntable body 12, turntable bearing 15, and roller 16. This significantly reduces the temperature fluctuation during long-term operation, prevents the cam 7 and roller 16 surfaces from being too tightly pressed together, ensures transmission efficiency, and avoids frictional heat loss that could cause the turntable body 12 to heat up, thus preventing temperature changes in the material being processed and ensuring processing accuracy.

[0033] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
