A noise-reducing cam divider

Abstract

This utility model relates to the field of cam divider technology and proposes a noise-reducing cam divider, including a cam divider, a buffer mechanism, and a lubrication mechanism. The cam divider consists of a housing, cam rollers, a common rail cam, and an indexing plate. The buffer mechanism is located at the bottom of the cam divider to buffer the vibrations generated during operation. The lubrication mechanism is located on one side of the housing to add lubricating oil between the cam rollers and the common rail cam. During the operation of the cam divider, vibrations caused by itself and external factors generate noise. The vibration force is transmitted through multiple springs and dampers via hinged support rods one and two, which are respectively connected between the fixed plate and the mounting plate. The combined effect of these springs and dampers effectively buffers and cancels the vibration force, thereby stabilizing the operation of the cam divider and controlling vibration and noise to a very small and smooth level.

Description

Technical Field

[0001] This utility model relates to the field of cam divider technology, specifically to a noise-reducing cam divider. Background Technology

[0002] A cam indexer, also known as a cam divider or intermittent divider in engineering, is a high-precision rotary device. In today's automation environment, cam indexers are particularly important. If there is any unevenness between the cam surface and the cam roller in the tapered support rib, the indexer will be damaged. Adjusting the distance between the shafts can eliminate this unevenness, and adjusting the preload can bring the indexer closer to the elastic zone of the cam roller and cam, thereby increasing its rigidity. Its structure and function represent the optimal combination of an indexing cam and a cam roller, enabling high-speed operation.

[0003] In the prior art, utility model patent with publication number CN208634305U proposes a noise reduction device for a high-speed precision divider of an arc-shaped cam, including a worktable, a movable plate, a divider body, a honeycomb plate, and a fixed plate. The upper surface of the worktable has an installation groove, and an installation rod is threaded onto the upper surface of the worktable. Slider blocks are fixed on both sides of the honeycomb plate and inserted into the installation groove. A sound-insulating damping plate is fixed on the lower surface of the honeycomb plate, and a perforated sound-absorbing plate is pasted on the lower surface of the sound-insulating damping plate. A rubber pad is fixed on the lower surface of the perforated sound-absorbing plate, and the lower surface of the rubber pad is fixed to the bottom of the inner wall of the installation groove. The lower surface of the fixed plate is inserted into the top of the installation rod, and fixed pins are installed on all four sides of the fixed plate. The movable plate is movably mounted on the fixed pins through movable pins. This device can effectively reduce the vibration between the device and the worktable, reduce noise generation, and effectively prevent noise diffusion.

[0004] However, the noise reduction device of the above-mentioned arc-face cam high-speed precision divider has the following problems: it is difficult to buffer the vibration of the cam divider itself and the external equipment, which will cause the internal parts of the cam divider to loosen and generate noise over time; and it is difficult to quickly add lubricating oil between the cam roller and the common rail cam, which will easily lead to insufficient lubricating oil between the cam roller and the common rail cam, resulting in wear and noise, thus failing to play the function of noise reduction. Utility Model Content

[0005] The purpose of this invention is to propose a noise-reducing cam divider to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a noise-reducing cam divider, comprising a cam divider, a buffer mechanism, and a lubrication mechanism; the cam divider consists of a housing, cam rollers, a common rail cam, and an indexing plate, the indexing plate being disposed on the top of the cam rollers, the cam rollers being disposed on the inner bottom wall of the housing via a base, the common rail cam rotating through the housing, and the common rail cam meshing with the cam rollers; the buffer mechanism is disposed at the bottom of the cam divider for buffering vibrations generated during the operation of the cam divider; the lubrication mechanism is disposed on one side of the housing for adding lubricating oil between the cam rollers and the common rail cam; sound-insulating cotton and sound-absorbing cotton are respectively disposed inside the housing, the sound-absorbing cotton being located inside the sound-insulating cotton, and the sound-insulating cotton being located inside the housing.

[0007] Preferably, the buffer mechanism includes a fixed plate fixedly installed at the bottom of the housing, a base mounting plate disposed below the fixed plate, and a mounting plate fixedly installed on the top of the base mounting plate.

[0008] Preferably, the top circular array of the mounting plate is hinged with a first support rod, and the bottom circular array of the fixing plate is hinged with a second support rod, the bottom end of the second support rod being hinged to the top end of the first support rod.

[0009] Preferably, multiple springs and dampers are fixedly installed between the fixed plate and the mounting plate, and the multiple springs are distributed sequentially around a multiple spring circular array.

[0010] Preferably, the lubrication mechanism includes a box fixedly installed on the inner wall of the housing, the box covering the outside of the common rail cam, and the two are rotatably connected through each other.

[0011] Preferably, an oil pipe is fixedly installed through one side of the housing, the rear end of the oil pipe extends into the interior of the box, and the front end of the oil pipe is threaded with a sealing cap.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] During the operation of the cam divider, vibrations caused by itself and external factors generate noise. The vibration force is transmitted through multiple springs and dampers by the hinged connection between the linkage support rod one and the mounting plate, respectively. With the cooperation of multiple springs and dampers, the vibration force is effectively buffered and offset, thereby making the cam divider run stably and controlling the vibration and noise to a very small and smooth level.

[0014] By manually rotating the sealing cap, the sealing cap moves in a threaded motion at the front end of the oil pipe, allowing the sealing cap to be opened and removed from the oil pipe. This effectively allows lubricating oil to be added to the inside of the box from the oil pipe, thereby adding lubricating oil to the common rail cam and preventing wear and noise caused by lack of lubrication between the common rail cam and the cam roller, thus effectively reducing noise.
