Description

Technical Field

[0001] This utility model relates to the technical field of cam dividers, and in particular to a spindle-type cam divider that is easy to assemble and disassemble. Background Technology

[0002] The spindle-type cam divider is a high-precision rotary device, mainly used to convert continuous rotary motion into periodic reciprocating motion. It uses a spindle as the output shaft and is suitable as a power source for intermittent conveyor belts, gear meshing and other mechanisms. The installation method of the spindle-type cam divider is even more important. Chinese utility model patent CN223301237U discloses a conveniently assembled and disassembled spindle-type cam divider. This cam divider includes a spindle-type cam divider body, with a mounting platform abutting one side of the body. The mounting platform has four sets of mounting holes arranged in a rectangular array on its top. The advantage of this utility model is that during equipment installation, the sliding block at the bottom of the spindle-type cam divider body slides into the fitting groove, thereby mounting the body onto the mounting platform. Then, a spring pushes a lifting plate, causing a positioning block to embed into the positioning groove, fixing the sliding block and the spindle-type cam divider body in place. This achieves rapid installation of the spindle-type cam divider body, solving the problem of slow replacement efficiency caused by the previous bolt-based method, and improving the replacement efficiency of the spindle-type cam divider body.

[0003] The aforementioned spindle-type cam divider uses a fitting groove with a positioning block and a slider to be installed and connected to the mounting table. A certain gap is set between the fitting groove and the slider to allow relative sliding. Moreover, the spindle-type cam divider is pressed against the mounting table by a spring, resulting in a small clamping force. Therefore, the spindle-type cam divider has low stability after installation, which is not conducive to the spindle-type cam divider outputting a large torque. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a convenient spindle-type cam divider that can be quickly and easily disassembled and assembled, is more stable after installation, and can output a stable high torque. It is also highly practical.

[0005] This utility model discloses a conveniently assembled and disassembled spindle-type cam divider, comprising a mounting platform, a cam divider body, and a base plate. The base plate is located at the bottom of the cam divider body. It also includes multiple mounting rod structures, a drive shaft, a drive disc, a pressure plate, and a screw. The base plate has multiple insertion holes aligned with mounting holes on the mounting platform. The multiple mounting rod structures pass through the insertion holes and mounting holes to quickly fix the base plate onto the mounting platform. The output shaft of the cam divider body is concentrically mounted with the drive shaft. A positioning block is located at the upper center of the drive shaft. A positioning hole matching the positioning block is located at the center of the drive disc. A threaded hole is located at the top center of the positioning block. A screw is located at the bottom of the pressure plate, and the screw is rotatably screwed into the threaded hole of the positioning block. The base plate is mounted on the mounting platform via the multiple mounting rod structures. Multiple mounting rods are designed as rod-shaped structures for quick installation and disassembly, enabling convenient assembly and disassembly of the cam divider body and mounting platform. It also offers the stability and high output torque of traditional bolt installation. The drive plate is used for transmission connection with external force-bearing components. During drive plate installation, rotating the pressure plate causes the screw to rotate upwards, aligning the pressure plate with the positioning block on the drive shaft. The drive plate is then fitted onto the positioning block through the positioning hole, ensuring limited contact between the drive plate and the end of the drive shaft. Rotating the pressure plate tightens the screw downwards, pressing the drive plate firmly, thus achieving rapid installation of the drive plate and drive shaft. At this point, the drive plate can output torque stably and efficiently. Compared to existing technologies, this design allows for quick and convenient assembly and disassembly, resulting in greater stability and a higher stable torque output, making it highly practical.

[0006] Preferably, it also includes multiple positioning pins, which are inserted into the pressure plate. The positioning block of the drive shaft is provided with pin holes that cooperate with the multiple positioning pins. When the pressure plate is tightened to press the drive disk, the multiple positioning pins are inserted into the pin holes respectively. By setting multiple positioning pins, the pressure plate pins are positioned to prevent the pressure plate from loosening and improve the stability of the drive disk installation.

[0007] Preferably, the mounting rod structure includes an insert rod, a shaft, two baffles, a limiting block, and a lifting structure. The lower part of the insert rod has a vertical slot, the shaft is installed at the bottom of the slot, the lower ends of the two baffles rotate with the shaft, and the upper ends of the two baffles can extend to the left and right sides of the slot. A limiting block is provided at the bottom of the slot of the insert rod, limiting the two baffles. A lifting structure is provided at the upper part of the insert rod for lifting the insert rod. In use, the lower part of the insert rod is inserted through the insertion hole of the base plate and the mounting hole of the mounting platform, so that the two baffles extend completely below the mounting platform. At this time, the upper ends of the two baffles flip towards both sides of the slot of the insert rod under the action of gravity and are limited and blocked by the limiting block. The lifting structure is used to lift the insert rod upwards, so that the insert rod, through the two baffles and the lifting structure, presses the mounting platform and the base plate together, achieving a convenient assembly and disassembly effect.

[0008] Preferably, the lifting structure includes a sleeve, an axle, and a track wheel. The sleeve is fitted onto the upper part of the insertion rod, and an inclined slide rail is provided at the upper end of the sleeve. The axle is installed on the upper side of the insertion rod, and the track wheel is rotatably mounted on the axle. The track wheel rolls along the inclined slide rail, and a groove for the track wheel is provided at the top of the inclined slide rail. When it is necessary to lift the insertion rod, a wrench or other tool is used to rotate the insertion rod, so that the insertion rod drives the track wheel to roll upward along the inclined slide rail through the axle until the track wheel is positioned and locked by the groove at the top of the inclined slide rail, thereby lifting the insertion rod upward, achieving quick and convenient installation and disassembly.

[0009] Preferably, the lifting structure includes an eccentric shaft, an eccentric wheel, and a handle. The eccentric shaft is installed on the upper side wall of the insertion rod, the eccentric wheel is rotatably installed on the eccentric shaft, and one end of the handle is connected to the eccentric wheel. When the insertion rod needs to be lifted, the handle is turned to drive the eccentric wheel to rotate around the eccentric shaft, so that the protrusion of the eccentric wheel presses against the base plate, thereby lifting the insertion rod upward in the opposite direction through the eccentric shaft, realizing quick and convenient installation and disassembly.

[0010] Preferably, the mounting rod structure includes an inner rod, a push block, a spring sleeve, and a wedge plate. The lower end of the inner rod has an outwardly protruding tapered portion. The spring sleeve is fitted into the lower middle part of the inner rod. The lower part of the spring sleeve has multiple dividing grooves. The lower end of the spring sleeve has an inclined surface that matches the tapered portion of the inner rod. The top of the inner rod has a push block. The upper part of the wedge plate has a wedge-shaped body. The wedge plate is inserted between the push block and the spring sleeve. The bottom of the wedge plate limits and blocks the spring sleeve, and the push block is pushed by the wedge-shaped body. The block is lifted upwards; in use, the lower part of the inner rod and spring sleeve is inserted through the insertion hole of the base plate and the mounting hole of the mounting platform. The wedge plate is inserted between the push block and the spring sleeve. The wedge plate is pushed further with tools such as a hammer, so that the bottom of the wedge plate limits and blocks the spring sleeve and the wedge body lifts the push block and inner rod upwards. The cone-shaped body at the bottom of the inner rod squeezes and pushes the lower part of the spring sleeve outwards, thereby making the inner rod and spring sleeve stably connected to the base plate and achieving the effect of easy disassembly and assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The base plate is mounted on the mounting platform via multiple mounting rods. These mounting rods are designed for quick installation and disassembly, allowing for easy assembly and disassembly of the cam divider body from the mounting platform. It also offers the stability and high output torque of traditional bolt installation. The system enables quick and convenient assembly and disassembly, provides greater stability after installation, and can output a stable high torque through the drive disc, making it highly practical.

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

[0015] like Figures 1 to 3 As shown, a conveniently assembled and disassembled spindle-type cam divider includes a mounting platform 1, a cam divider body 2, and a base plate 3. The base plate 3 is located at the bottom of the cam divider body 2. It also includes multiple mounting rod structures 4, a drive shaft 5, a drive disc 6, a pressure plate 7, and a screw 8. The base plate 3 has multiple insertion holes aligned with the mounting holes on the mounting platform 1. The multiple mounting rod structures 4 pass through the insertion holes and mounting holes to quickly fix the base plate 3 onto the mounting platform 1. The output shaft of the cam divider body 2 is concentrically mounted with the drive shaft 5. A positioning block is located at the upper center of the drive shaft 5. A positioning hole matching the positioning block is located at the center of the drive disc 6. A threaded hole is located at the top center of the positioning block. A screw 8 is located at the bottom of the pressure plate 7 and is rotatably screwed into the threaded hole of the positioning block. It also includes multiple positioning pins 9, which are inserted into the pressure plate 7. The positioning block of the drive shaft 5 has pin holes that mate with the multiple positioning pins 9. When the pressure plate 7 is tightened to press the drive disc 6, the multiple positioning pins 9 are inserted into the pin holes.

[0016] The base plate 3 is mounted on the mounting platform 1 via multiple mounting rod structures 4. These mounting rod structures 4 are designed as rod-shaped structures that can be quickly installed and disassembled, enabling convenient assembly and disassembly of the cam divider body 2 and the mounting platform 1. This design also provides the stability and high output torque of traditional bolt installation. The drive plate 6 is used for transmission connection with external force-bearing components. When installing the drive plate 6, rotating the pressure plate 7 causes the screw 8 to rotate upwards, aligning the pressure plate 7 with the positioning block on the drive shaft 5. The drive plate 6 is then fitted onto the positioning block through the positioning hole, ensuring that the drive plate 6 makes limited contact with the end of the drive shaft 5. Rotating the pressure plate 7 causes the screw 8 to tighten downwards, pressing the drive plate 6 firmly. Multiple positioning pins 9 position the pressure plate 7, preventing it from loosening and improving the stability of the drive plate 6 installation. This allows for quick installation of the drive plate 6 and the drive shaft 5. At this point, the drive plate 6 can output torque stably and efficiently. Compared to existing technologies, this design allows for quick and convenient assembly and disassembly, resulting in greater stability and a higher torque output after installation, making it highly practical.

[0018] In use, insert the lower part of the insertion rod 10 through the insertion hole of the base plate 3 and the mounting hole of the mounting platform 1, so that the two baffles 12 extend completely under the mounting platform 1. At this time, the upper ends of the two baffles 12 flip towards the slots of the insertion rod 10 under the action of gravity and are blocked by the limiting block 13. The lifting structure is used to lift the insertion rod 10 upward, so that the insertion rod 10 presses the mounting platform 1 and the base plate 3 together through the two baffles 12 and the lifting structure, so as to achieve the effect of convenient disassembly and assembly.
