Description

Technical Field

[0001] This utility model relates to the technical field of display platforms, and in particular to an eight-axis linkage cam divider display platform. Background Technology

[0002] Cam dividers typically have one input shaft and one or more output shafts, with common types including single-axis linkage, dual-axis linkage, four-axis linkage, and eight-axis linkage. Chinese utility model patent CN222200446U discloses an eight-axis linkage cam divider display platform. This platform includes a support platform and a hydraulic cylinder mounted on the upper surface of the support platform. It also includes: a bearing plate connected to the output end of the hydraulic cylinder, a worktable mounted on the upper surface of the bearing plate, a cam divider mounted on the worktable, and a linkage shaft connected to the output end of the cam divider; a first rotating platform below the linkage shaft, and a second rotating platform to the left of the first rotating platform, both mounted on the top of a rotating rod; a positioning structure, including a sleeve, is provided below the rotating rod for easy assembly and disassembly of the first and second rotating platforms. This eight-axis linkage cam divider display platform, through the positioning structure, allows for the assembly and disassembly of the rotating rod, and through the rotating rod, the assembly and disassembly of the first and second rotating platforms, thus facilitating maintenance work.

[0003] However, the aforementioned display platform cannot rotate to display the eight-axis linkage cam divider, resulting in an incomplete display. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an eight-axis linkage cam divider display platform that can drive the display stand to rotate using the output shaft of the eight-axis linkage cam divider, so as to fully display the eight-axis linkage cam divider and achieve a good display effect.

[0005] This utility model discloses an eight-axis linkage cam divider display platform, including an upper platform; it also includes a display stand, an eight-axis linkage cam divider, a motor, multiple rollers, multiple drive shafts, and a transmission assembly. The display stand is rotatably mounted on the upper platform, and the eight-axis linkage cam divider and motor are mounted on the display stand. The output shaft of the motor is drivenly connected to the input shaft of the eight-axis linkage cam divider. The eight-axis linkage cam divider has eight output shafts. Multiple rollers are evenly arranged circumferentially on the outer side of the display stand. Multiple drive shafts are rotatably mounted on the display stand, and multiple rollers are respectively mounted on the outer ends of multiple drive shafts. Two output shafts of the eight-axis linkage cam divider are drivenly connected to two drive shafts through the transmission assembly, driving two rollers to rotate. The output shaft of the motor drives the input shaft of the eight-axis linkage cam divider to rotate, causing the eight output shafts of the eight-axis linkage cam divider to rotate intermittently. The cutter has two output shafts that drive two drive shafts and two rollers to rotate via a transmission assembly. When two output shafts rotate in the same direction, they drive the two drive shafts and rollers to rotate intermittently, causing the display stand to rotate unidirectionally on the upper platform, providing a full display of the eight-axis linkage cam divider. When two output shafts rotate in opposite directions, the transmission assembly drives one drive shaft and roller to rotate forward, while the other drive shaft and roller are disconnected from the transmission. This causes one drive shaft and roller to drive the display stand to rotate intermittently in the forward direction, while the other drive shaft and roller rotate in the reverse direction. The transmission assembly then disconnects the transmission, causing the other drive shaft and roller to drive the display stand to rotate intermittently in the reverse direction. This intermittent reciprocating rotation of the display stand provides a full display of the eight-axis linkage cam divider and shows the output effect of the two output shafts, resulting in a good display effect.

[0006] Preferably, the transmission assembly includes gear one, gear two, gear three, and gear four. Gear one is concentrically mounted on one output shaft of the eight-axis linkage cam divider, gear two is concentrically mounted on a drive shaft and meshes with gear one, gear three is concentrically mounted on another output shaft of the eight-axis linkage cam divider, and gear four is concentrically mounted on another drive shaft and meshes with gear three. When the two output shafts of the eight-axis linkage cam divider rotate in the same direction, gear one and gear three are full gears. At this time, gear one meshes with gear two to drive a drive shaft and a roller to rotate. Gear 3 meshes with gear 4, driving another drive shaft and roller to rotate, thus causing the display stand to rotate in one direction. When the two output shafts of the eight-axis linkage cam divider rotate in opposite directions, gear 1 and gear 3 are half gears. When gear 1 meshes with gear 2, gear 3 disengages from gear 4, thus driving only one drive shaft and roller to rotate in the forward direction, causing the display stand to rotate in the forward direction. When gear 3 meshes with gear 4, gear 1 disengages from gear 2, thus driving only the other drive shaft and roller to rotate in the reverse direction, causing the display stand to rotate in the reverse direction, thus causing the display stand to rotate intermittently and repeatedly.

[0007] Preferably, the device also includes a first swing arm, a contact switch, and a second swing arm. The outer end of the first swing arm is mounted on one output shaft of the eight-axis linkage cam divider, and the inner end of the first swing arm is mounted on the contact switch. The outer end of the second swing arm is mounted on the other output shaft of the eight-axis linkage cam divider. The two output shafts rotate relative to each other, and the first and second swing arms are arranged opposite each other. The inner end of the second swing arm is provided with the contact plate of the contact switch. The two output shafts of the eight-axis linkage cam divider drive the first and second swing arms to rotate relative to each other. When the inner ends of the first and second swing arms are opposite each other, the contact end of the contact switch contacts the contact plate on the second swing arm, thereby generating an electrical signal. The frequency of the generated electrical signal is detected. When the frequency remains stable for a long time, it indicates that the rotational accuracy of the two output shafts meets the requirements. When the frequency becomes unstable for a short time, it indicates that the first and second swing arms cannot be aligned at the specified position, and the rotational accuracy of the two output shafts does not meet the requirements, thus demonstrating the output accuracy.

[0008] Preferably, the assembly also includes turntable one, turntable two, and photoelectric switches. Multiple turntable one and multiple turntable two are provided, and multiple photoelectric switches are provided. Multiple turntable one and multiple turntable two are concentrically mounted on multiple output shafts of the eight-axis linkage cam divider. Turntable one and turntable two are arranged alternately. Multiple through holes one are evenly distributed around the circumference of turntable one, and multiple through holes two are distributed around the circumference of turntable two. The through holes one and through holes two at the intersection of turntable one and turntable two are concentrically aligned. The photoelectric switches are mounted on the eight-axis linkage cam divider, and the photoelectric emitter of the photoelectric switch is located below the aligned through holes one and through holes two. The number of through holes one on turntable one is the same as the number of rotations of its output shaft, and the number of through holes two on turntable two is the same as the number of rotations of its output shaft. The number of steps in one revolution of the shaft is the same. The multiple output shafts of the eight-axis linkage cam divider drive multiple turntables 1 and 2 to rotate intermittently, and make the through holes 1 and 2 at the intersection of multiple turntables 1 and 2 concentrically aligned. At this time, the photoelectric head of the photoelectric switch emits a photoelectric signal that passes through through holes 1 and 2. The photoelectric switch does not receive the reflected signal, thus generating an electrical signal. The frequency of the generated electrical signal is detected. When the frequency remains stable for a long time, it indicates that the rotation accuracy of multiple output shafts meets the requirements. When the frequency becomes unstable for a short time, it indicates that multiple turntables 1 and 2 cannot be aligned at the specified position, and the rotation accuracy of multiple output shafts does not meet the requirements, thus displaying the output accuracy.

[0009] Preferably, it also includes a magnetic base and a positioning block. The magnetic base is magnetically attached to the eight-axis linkage cam divider. The upper end surface of the magnetic base is provided with a raised positioning block. The bottom of the photoelectric switch is provided with a positioning groove that matches the positioning block. The bottom of the photoelectric switch is magnetically attached to the magnetic base. The photoelectric switch is positioned and locked with the positioning block through the positioning groove, which makes the photoelectric switch easy and quick to install and remove, and improves the positioning accuracy of the photoelectric switch.

[0010] Preferably, it also includes a lower platform, multiple sliding rods, and a push cylinder. The bottom of the lower platform is provided with multiple support legs, and multiple sliding rods are vertically installed on the lower end face of the upper platform. The multiple sliding rods are slidably connected to the lower platform. The fixed end of the push cylinder is installed on the lower platform, and the piston rod end of the push cylinder is connected to the upper platform. When the piston rod of the push cylinder extends, it pushes the upper platform to rise. When the piston rod of the push cylinder retracts, it drives the upper platform to fall. When the upper platform rises and falls, the multiple sliding rods cooperate with the lower platform to slide and limit, thereby adjusting the height of the upper platform for easy display.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The output shaft of the motor drives the input shaft of the eight-axis linkage cam divider to rotate, causing the eight output shafts of the eight-axis linkage cam divider to rotate intermittently. Two output shafts on the eight-axis linkage cam divider drive two drive shafts and two rollers to rotate through a transmission assembly. When two output shafts rotating in the same direction are selected, the two drive shafts and two rollers are driven to rotate intermittently, thereby causing the display stand to rotate unidirectionally on the upper platform, providing a full display of the eight-axis linkage cam divider. When two output shafts rotating in opposite directions are selected, the transmission assembly drives one drive shaft and roller to rotate in the forward direction, while the other drive shaft and roller are disconnected from the transmission, causing one drive shaft and roller to drive the display stand to rotate intermittently in the forward direction. The transmission assembly drives the other drive shaft and roller to rotate in the reverse direction, while the other drive shaft and roller are disconnected from the transmission, causing the other drive shaft and roller to drive the display stand to rotate intermittently in the reverse direction. This causes the display stand to rotate intermittently back and forth, providing a full display of the eight-axis linkage cam divider and showing the output effect of the two output shafts of the eight-axis linkage cam divider, resulting in a good display effect.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0020] like Figures 1 to 4 As shown, an eight-axis linkage cam divider display platform includes an upper platform 1; it also includes a display stand 2, an eight-axis linkage cam divider 3, a motor 4, multiple rollers 5, multiple drive shafts 6, and a transmission assembly. The display stand 2 is rotatably mounted on the upper platform 1. The eight-axis linkage cam divider 3 and the motor 4 are mounted on the display stand 2. The output shaft of the motor 4 is connected to the input shaft of the eight-axis linkage cam divider 3. The eight-axis linkage cam divider 3 has eight output shafts. The multiple rollers 5 are evenly arranged circumferentially on the outer side of the display stand 2. The multiple drive shafts 6 are rotatably mounted on the display stand 2. The multiple rollers 5 are respectively mounted on the outer ends of the multiple drive shafts 6. Two output shafts of the eight-axis linkage cam divider 3 are connected to two drive shafts 6 through the transmission assembly, driving the two rollers 5 to rotate. The transmission assembly includes gear 7, gear 8, gear 9, and gear 10. Gear 7 is concentrically mounted on one output shaft of the eight-axis linkage cam divider 3. Gear 8 is concentrically mounted on a drive shaft 6 and meshes with gear 7. Gear 9 is concentrically mounted on another output shaft of the eight-axis linkage cam divider 3. Gear 10 is concentrically mounted on another drive shaft 6 and meshes with gear 10. The assembly also includes a lower platform 19, multiple slide rods 20, and a push cylinder 21. Multiple support legs are provided at the bottom of the lower platform 19. Multiple slide rods 20 are vertically mounted on the lower end face of the upper platform 1 and are slidably connected to the lower platform 19. The fixed end of the push cylinder 21 is mounted on the lower platform 19, and the piston rod end of the push cylinder 21 is connected to the upper platform 1.

[0021] When the piston rod of the push cylinder 21 extends, it pushes the upper platform 1 to rise; when the piston rod of the push cylinder 21 retracts, it drives the upper platform 1 to fall. During the raising and lowering of the upper platform 1, multiple sliding rods 20 cooperate with the lower platform 19 to slide and limit, thereby adjusting the height of the upper platform 1 for easy display. When the two output shafts of the eight-axis linkage cam divider 3 rotate in the same direction, gear 1 7 and gear 3 9 are full gears. At this time, gear 1 7 meshes with gear 2 8 to drive one drive shaft 6 and roller 5 to rotate, while gear 3 9 meshes with gear 4 10 to drive another drive shaft 6 and roller 5 to rotate, thereby driving the display stand 2 to rotate in one direction. The output shaft of the motor 4 drives the input shaft of the eight-axis linkage cam divider 3 to rotate, so that the eight axes of the eight-axis linkage cam divider 3 rotate. The output shafts rotate intermittently. When the two output shafts of the eight-axis linkage cam divider 3 rotate in opposite directions, gear 1 7 and gear 3 9 are half gears. When gear 1 7 meshes with gear 2 8, gear 3 9 disengages from gear 4 10, thus driving only one drive shaft 6 and roller 5 to rotate in the forward direction, causing the display platform 2 to rotate in the forward direction. When gear 3 9 meshes with gear 4 10, gear 1 7 disengages from gear 2 8, thus driving only the other drive shaft 6 and roller 5 to rotate in the reverse direction, causing the display platform 2 to rotate in the reverse direction. This intermittently and repeatedly rotates the display platform 2, providing a comprehensive display of the eight-axis linkage cam divider 3 and showing the output effect of the two output shafts of the eight-axis linkage cam divider 3, resulting in a good display effect. Example 2

[0022] like Figure 2 and Figure 5 As shown, based on Embodiment 1, it also includes a first swing arm 11, a contact switch 12, and a second swing arm 13. The outer end of the first swing arm 11 is mounted on one output shaft of the eight-axis linkage cam divider 3, and the contact switch 12 is mounted on the inner end of the first swing arm 11. The outer end of the second swing arm 13 is mounted on the other output shaft of the eight-axis linkage cam divider 3. The two output shafts rotate relative to each other, and the first swing arm 11 and the second swing arm 13 are arranged opposite to each other. The contact plate of the contact switch 12 is provided on the inner end of the second swing arm 13.

[0023] The two output shafts of the eight-axis linkage cam divider 3 drive the first swing arm 11 and the second swing arm 13 to rotate relative to each other. When the inner ends of the first swing arm 11 and the second swing arm 13 are opposite each other, the contact end of the contact switch 12 contacts the contact plate on the second swing arm 13, thereby generating an electrical signal. The frequency of the generated electrical signal is detected. When the frequency remains stable for a long time, it indicates that the rotational accuracy of the two output shafts meets the requirements. When the frequency becomes unstable in a short time, it indicates that the first swing arm 11 and the second swing arm 13 cannot be aligned at the specified position, and the rotational accuracy of the two output shafts does not meet the requirements, thus displaying the output accuracy. Example

[0024] like Figures 1 to 4 and Figure 6As shown, based on Embodiment 1, it also includes a first turntable 14, a second turntable 15, and a photoelectric switch 16. Multiple first turntables 14, multiple second turntables 15, and multiple photoelectric switches 16 are provided. Multiple first turntables 14 and multiple second turntables 15 are concentrically mounted on multiple output shafts of the eight-axis linkage cam divider 3. The first turntables 14 and second turntables 15 are arranged alternately. Multiple through holes 1 are evenly distributed around the circumference of the first turntable 14, and multiple through holes 2 are distributed around the circumference of the second turntable 15. The through holes 1 and 2 at the intersection of disk 14 and turntable 2 are concentrically aligned. The photoelectric switch 16 is mounted on the eight-axis linkage cam divider 3, and the photoelectric emitting end of the photoelectric switch 16 is located below the aligned through holes 1 and 2. It also includes a magnetic base 17 and a positioning block 18. The magnetic base 17 is magnetically attached to the eight-axis linkage cam divider 3. The upper end surface of the magnetic base 17 is provided with a protruding positioning block 18, and the bottom of the photoelectric switch 16 is provided with a positioning groove that matches the positioning block 18.

[0025] The bottom of the photoelectric switch 16 is magnetically attached to the magnetic base 17. The photoelectric switch 16 is positioned and locked to the positioning block 18 through the positioning groove, making it easy and quick to install and remove, and improving the positioning accuracy of the photoelectric switch 16. The number of through holes in turntable 14 is set to be the same as the number of steps of one rotation of its output shaft, and the number of through holes in turntable 15 is set to be the same as the number of steps of one rotation of its output shaft. The multiple output shafts of the eight-axis linkage cam divider 3 drive multiple turntables 14 and multiple turntables 15 to rotate intermittently, and make multiple turntables 14 and multiple turntables 15 rotate intermittently. When the through holes 1 and 2 at the intersection of disk 2 15 are concentrically aligned, the photoelectric sensor of photoelectric switch 16 emits a photoelectric signal that passes through through holes 1 and 2. Since photoelectric switch 16 does not receive the reflected signal, it generates an electrical signal. The frequency of the generated electrical signal is detected. When the frequency remains stable for a long time, it indicates that the rotational accuracy of multiple output shafts meets the requirements. When the frequency becomes unstable in a short time, it indicates that multiple turntables 1 14 and multiple turntables 2 15 cannot be aligned at the specified position, and the rotational accuracy of multiple output shafts does not meet the requirements, thus demonstrating the output accuracy.

[0026] like Figures 1 to 6As shown, this utility model discloses an eight-axis linkage cam divider display platform. During operation, the output shaft of motor 4 first drives the input shaft of the eight-axis linkage cam divider 3 to rotate, causing the eight output shafts of the eight-axis linkage cam divider 3 to rotate intermittently. The first and second output shafts of the eight-axis linkage cam divider 3 drive two drive shafts 6 and two rollers 5 to rotate via a transmission assembly, causing the display stand 2 to rotate on the upper platform 1, providing a full display of the eight-axis linkage cam divider 3. Then, the third and fourth output shafts of the eight-axis linkage cam divider 3 drive swing arms 11 and 23 to rotate relative to each other. When the inner ends of swing arms 11 and 23 are aligned, the contact end of the contact switch 12 contacts the contact plate on swing arm 23, generating an electrical signal. The frequency of the generated electrical signal is detected. If the frequency remains stable for a long time, it indicates that the rotational accuracy of the two output shafts meets the requirements. If the frequency becomes unstable within a short time, it indicates that swing arms 11 and 23 cannot be aligned at the specified position, and the two output shafts... The rotational accuracy cannot meet the requirements; then, turntable 14 is concentrically installed on the fifth and seventh output shafts of the eight-axis linkage cam divider 3, and turntable 25 is concentrically installed on the sixth and eighth output shafts of the eight-axis linkage cam divider 3. The fifth, sixth, seventh and eighth output shafts of the eight-axis linkage cam divider 3 drive the two turntables 14 and the two turntables 25 to rotate intermittently, and make the through holes 1 and 2 at the intersection of the multiple turntables 14 and the multiple turntables 25 concentrically aligned. At this time, the photoelectric head of the photoelectric switch 16 emits a photoelectric signal that passes through the through holes 1 and 2. The photoelectric switch 16 does not receive the reflected signal and thus generates an electrical signal. The frequency of the generated electrical signal is detected. When the frequency remains stable for a long time, it indicates that the rotational accuracy of the multiple output shafts meets the requirements. When the frequency becomes unstable in a short time, it indicates that the multiple turntables 14 and the multiple turntables 25 cannot be aligned at the specified position, and the rotational accuracy of the multiple output shafts does not meet the requirements. Finally, the output accuracy can be displayed through an external display.

[0027] The main functions achieved by this utility model are:

[0028] 1. The output shaft of the eight-axis linkage cam divider 3 can be used to drive the display stand 2 to rotate, so as to fully display the eight-axis linkage cam divider 3 and achieve a good display effect.

[0029] 2. It can detect and display the rotational accuracy of multiple output shafts of the eight-axis linkage cam divider 3;

[0030] 3. The height of the eight-axis linkage cam divider 3 can be adjusted for easy full display.

[0031] This utility model discloses an eight-axis linkage cam divider display platform. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented. The upper platform 1, display table 2, eight-axis linkage cam divider 3, motor 4, roller 5, drive shaft 6, gear 1 7, gear 2 8, gear 3 9, gear 4 10, swing arm 1 11, swing arm 2 13, contact switch 12, turntable 1 14, turntable 2 15, photoelectric switch 16, magnetic base 17, slide rod 20, and push cylinder 21 are all commercially available.
