It has the advantages of high structure and good stability. However, the existing cam dividers still have certain defects, such as:

[0003] For example, a cam divider with announcement number CN108488337B includes a housing, a shift cam located in the housing, and an output turret with a plurality of cam rollers. Both ends of the shift cam have input shafts, which pass through the housing and are sealed with the housing. An oil chamber is provided in the housing just below the shift cam, an oil filling hole is provided on the housing above the oil chamber, and an oil drain hole is provided on the side wall of the oil chamber. The lower part of the gear teeth of the shift cam extends into the oil chamber, and a liquid level regulating mechanism is provided in the oil chamber to regulate the height of the lubricating oil level in the oil chamber. The output turret is provided with a particle attraction structure that can attract and position particles generated by the wear of the cam roller and the shift cam. This invention has the advantage of being able to achieve lubrication with a small amount of lubricating oil;

[0004] The above-mentioned cam divider can achieve the advantage of lubrication through a small amount of lubricating oil. However, after the cam divider is used for a long time, the internal temperature gradually increases with the use time. If the heat cannot be dissipated in time, it is easy to cause damage to the internal parts of the device. Utility Model Content

[0005] The utility model aims to provide a drive-integrated cam divider to solve the problem in the above-mentioned background technology that when the heat cannot be dissipated in time, the parts inside the device are easily damaged.

[0006] To achieve the above object, the utility model provides the following technical solution: a drive-integrated cam divider, comprising a cam divider body and a drive shaft arranged outside the cam divider body, a base is arranged at the lower end of the cam divider body, and a heat dissipation port is opened at the rear end of the cam divider body;

[0007] A positioning rod is fixedly mounted on the surface of the base, and a buffer protection mechanism is provided on the surface of the positioning rod;

[0008] An air guide plate is bolted on the inner side of the rear end of the base, and an auxiliary heat dissipation mechanism is arranged on the upper end of the air guide plate.

[0009] Furthermore, the number of the drive shafts is three, and the drive shafts are arranged on the left and right sides and the front end of the cam divider body.

[0010] Furthermore, the buffer protection mechanism is provided with a moving block, and the middle end of the moving block is installed through the surface of the positioning rod, and the upper end of the moving block is rotatably installed with a buffer rod, and the upper end of the buffer rod is rotatably installed at the bottom of the cam divider body.

[0011] Furthermore, a return spring is nested on the surface of the positioning rod, and the left and right ends of the return spring are fixedly installed between the moving block and the base, and a damping rod is fixedly installed between the base and the cam divider body.

[0012] Furthermore, the auxiliary heat dissipation mechanism is provided with an airbag, and the airbag is fixedly mounted on the bottom base, and the airbag is located on the front and rear sides of the positioning rod, and the material of the airbag is elastically set.

[0013] Furthermore, an air guide tube is installed through the upper end of the airbag, and the middle end of the air guide tube is limited by a limiter, and the lower end of the limiter is fixedly installed on the surface of the base, and the upper end of the air guide tube is fixedly installed on the bottom of the air guide plate.

[0014] Furthermore, an air outlet is fixedly installed on the upper end of the air guide plate, and the output end of the air outlet is aligned with the inside of the heat dissipation port, and a one-way air inlet is installed through the outside of the airbag, and a one-way valve is arranged inside the one-way air inlet.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. A driving shaft capable of driving an integrated device is provided. The driving shafts are provided on the left and right sides and the front end of the cam divider body. The number of driving shafts is set to three, which can make the device have a stronger driving effect and drive the integrated cam divider at the same time, which can improve the driving efficiency of the device;

[0017] Furthermore, a mounting base is provided at the lower end of the cam divider body, which can be conveniently installed. At the same time, a heat dissipation port is provided at the rear end of the cam divider body, which can provide heat dissipation effect for the cam divider, thereby preventing the cam divider body from being damaged by excessive temperature when working, thereby improving the service life of the device.

[0018] Furthermore, a buffer protection component is provided between the base and the cam divider body. When the cam divider body is subjected to vibration force, the cam divider body presses down the buffer rod. Since the buffer rod is rotatably installed at both ends, when the buffer rod is pressed, the moving block is pushed to slide along the positioning rod to squeeze the reset spring. The reset spring buffers the pressure through its own elastic force. At the same time, through the damping rod between the base and the cam divider body, the damping rod can relieve the pressure on the reset spring, so as to avoid the reset spring from vibrating back and forth due to its own elastic force after the buffering is completed, so as to achieve the effect of shock absorption and protect the device.

[0019] 2. An air outlet that can assist in heat dissipation is provided. After the cam divider body vibrates, the moving block is affected by the elastic force of the return spring and slides in the opposite direction along the positioning rod to squeeze the airbag. The airbag is squeezed and the air inside is transported to the air guide plate through the air guide pipe. At this time, the air guide pipe is fixed by the limiter to avoid disordered winding. When the air guide plate is inflated by the air guide pipe, the air guide plate outputs the gas into the heat dissipation port through the air outlet, which can play an auxiliary heat dissipation effect and improve the heat dissipation efficiency of the device;

[0020] Furthermore, the airbag is elastically arranged so that when the airbag stops being squeezed by the moving block, the airbag resets itself through its own elasticity. At this time, the airbag can only take in air through the one-way valve inside the one-way air inlet, and the airbag is re-inflated, so that the airbag can be recycled without manual handling.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1 and Figure 2 The technical solution shown, in order to solve the problem of unstable driving of the cam divider, discloses: a cam divider body 1 and a driving shaft 2 arranged outside the cam divider body 1, a base 3 is arranged at the lower end of the cam divider body 1, and a heat dissipation port 4 is opened at the rear end of the cam divider body 1, the number of the driving shafts 2 is three, and the driving shafts 2 are arranged on the left and right sides and the front end of the cam divider body 1;

[0031] In this example, a driving shaft 2 capable of driving an integrated device is provided. The driving shafts 2 are provided on the left and right sides and the front end of the cam divider body 1. The number of driving shafts 2 is three, which can make the device have a stronger driving effect and drive the integrated cam divider at the same time, which can improve the driving efficiency of the device. A mounting base 3 is provided at the lower end of the cam divider body 1, which can be easily installed. At the same time, a heat dissipation port 4 is provided at the rear end of the cam divider body 1, which can provide heat dissipation effect for the cam divider, avoid the cam divider body 1 from being damaged by excessive temperature when working, and improve the service life of the device.

[0032] Embodiment 2:

[0033] like Figure 1 , Figure 3 , Figure 4 and Figure 5 The technical solution shown, in order to solve the problem that the cam divider is easily damaged by vibration, discloses a buffer protection mechanism: a positioning rod 5 is fixedly installed on the surface of the base 3, and a buffer protection mechanism is arranged on the surface of the positioning rod 5, and the buffer protection mechanism is arranged on a moving block 6, and the middle end of the moving block 6 is installed through the surface of the positioning rod 5, and a buffer rod 7 is rotatably installed on the upper end of the moving block 6, and the upper end of the buffer rod 7 is rotatably installed on the bottom of the cam divider body 1, a return spring 8 is nested on the surface of the positioning rod 5, and the left and right ends of the return spring 8 are fixedly installed between the moving block 6 and the base 3, and a damping rod 9 is fixedly installed between the base 3 and the cam divider body 1;

[0034] In this example, a buffer protection component is arranged between the base 3 and the cam divider body 1. When the cam divider body 1 is subjected to a vibration force, the cam divider body 1 presses down the buffer rod 7. Since the buffer rod 7 is rotatably mounted at both ends, when the buffer rod 7 is pressed, the moving block 6 is pushed to slide along the positioning rod 5 to squeeze the reset spring 8. The reset spring 8 buffers the pressure through its own elastic force. At the same time, through the damping rod 9 between the base 3 and the cam divider body 1, the damping rod 9 can relieve the pressure on the reset spring 8, so as to avoid the reset spring 8 from vibrating back and forth due to its own elastic force after the buffering is completed, so as to achieve a shock-absorbing effect and protect the device.

[0035] Embodiment three:

[0036] like Figure 1-Figure 6 The technical solution shown, in order to solve the problem of poor heat dissipation effect of the buffer protection mechanism, discloses an auxiliary heat dissipation mechanism: an air guide plate 12 is bolted to the inner side of the rear end of the base 3, and an auxiliary heat dissipation mechanism is arranged on the upper end of the air guide plate 12, the auxiliary heat dissipation mechanism is provided with an air bag 10, and the air bag 10 is fixedly installed on the bottom base 3, and the air bag 10 is located at the front and rear sides of the positioning rod 5, and the material of the air bag 10 is elastically set, an air guide tube 11 is installed through the upper end of the air bag 10, and the middle end of the air guide tube 11 is limited by a limiter 14, and the lower end of the limiter 14 is fixedly installed on the surface of the base 3, and the upper end of the air guide tube 11 is fixedly installed on the bottom of the air guide plate 12, an air outlet 13 is fixedly installed on the upper end of the air guide plate 12, and the output end of the air outlet 13 is aligned with the inside of the heat dissipation port 4, and a one-way air inlet 15 is installed through the outer side of the air bag 10, and a one-way valve is arranged inside the one-way air inlet 15;

[0037] In this example, an air outlet 13 is provided to assist in heat dissipation. After the cam divider body 1 completes vibration, the moving block 6 is affected by the elastic force of the return spring 8 and slides in the opposite direction along the positioning rod 5 to squeeze the airbag 10. The airbag 10 is squeezed to deliver the internal air to the air guide plate 12 through the air guide tube 11. At this time, the air guide tube 11 is fixed by the limiting member 14 to avoid disordered entanglement. When the air guide plate 12 is inflated by the air guide tube 11, the air guide plate 12 outputs the gas into the heat dissipation port 4 through the air outlet 13, which can assist in heat dissipation and improve the heat dissipation efficiency of the device. The airbag 10 is elastically arranged. When the airbag 10 stops being squeezed by the moving block 6, the airbag 10 is reset by its own elasticity. At this time, the airbag 10 can only take in air through the one-way valve inside the one-way air inlet 15, and the airbag 10 is re-inflated so that the airbag 10 can be recycled without manual handling.
