Description

Technical Field

[0001] This application relates to the field of chain beveling equipment, and more particularly to a beveling machine. Background Technology

[0002] Chainrings are widely used in transmission systems in industrial production, and their performance directly affects the stability and efficiency of equipment operation. To ensure smooth transmission during operation, chainrings typically require chamfering of sharp corners to prevent wear or jamming caused by these corners. Currently, the industry mainly uses the following methods for chamfering chainring corners: first, the traditional manual grinding method, where workers use grinding tools to process each chainring individually; second, fixed chamfering machines, which use cutting tools to mechanically process the chainrings, but require pre-adjustment of the equipment to fit chainrings of specific sizes; and third, semi-automatic chamfering devices, which use simple positioning fixtures in conjunction with manual operation to complete the processing. These methods meet production needs to a certain extent, but still have significant limitations.

[0003] The aforementioned existing technologies generally suffer from a lack of flexibility. In particular, fixed chamfering machines are only suitable for chainrings of a single size, failing to meet the processing needs of chainrings of multiple sizes. Furthermore, while manual polishing is simple and easy, its reliance on manual operation easily leads to uneven chamfering, causing chainring jams or seizing during use, severely impacting the stability of the transmission system and the lifespan of the chainring. Therefore, there is an urgent need for chamfering equipment capable of adapting to chainrings of different sizes to improve processing efficiency and product quality. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a chamfering machine.

[0005] This application provides a chamfering machine, which adopts the following technical solution:

[0006] A chamfering machine includes a base, a rotating mechanism mounted on the base, a worktable connected to the rotating mechanism for placing a chain reel, a positioning mechanism mounted on the worktable for positioning the chain reel, a mounting bracket mounted on the base, and a cutting head mechanism mounted on the mounting bracket. The mounting bracket is provided with an adjustment mechanism for adjusting the position of the cutting head mechanism. The mounting bracket includes two first support rods mounted on the base and a mounting rod positioned on top of the first support rods. The two first support rods are symmetrically arranged on opposite sides of the worktable, and the mounting rod is positioned above the worktable.

[0007] By adopting the above technical solution, the chamfering machine can chamfer chain discs of different sizes. The base provides a stable support foundation for the entire equipment. The rotating mechanism drives the worktable and the chain discs placed on it to rotate, and the positioning mechanism ensures the stability and positional accuracy of the chain discs during processing. The mounting frame provides a stable mounting position for the cutter head mechanism through two symmetrically arranged first support rods and an upper mounting rod. At the same time, the adjustment mechanism can flexibly adjust the position of the cutter head mechanism to adapt to the processing requirements of chain discs of different sizes, thereby effectively solving the problems of uneven chamfering and poor flexibility in the existing technology, improving processing efficiency and chain disc quality.

[0008] Preferably, the adjusting mechanism includes an mounting groove on the mounting rod, an adjusting screw in the mounting groove, two mounting plates in the mounting groove, an adjusting handle at one end of the adjusting screw, and a mounting block in the mounting groove. The two mounting plates are rotatably connected to both ends of the adjusting screw, the mounting block is threadedly connected to the adjusting screw, the mounting block has a connecting groove, the mounting rod is slidably connected to the connecting groove, and the mounting block is connected to the cutter head mechanism.

[0009] By adopting the above technical solution, the adjustment mechanism allows for flexible adjustment of the cutter head mechanism's position. The threaded connection between the adjusting screw and the mounting block, along with the sliding connection between the mounting block and the mounting rod, enables precise control of the mounting block's movement when the adjusting screw is rotated, thus achieving accurate adjustment of the cutter head mechanism's position. The adjustable handle facilitates operator application of force, improving adjustment efficiency. This adjustment mechanism allows the chamfering machine to adapt to the processing needs of chain tracks of different sizes, effectively solving the problem of poor flexibility in the use of existing chamfering machines.

[0010] Preferably, the cutter head mechanism includes a drive motor, a reduction gearbox driven by the drive motor, and a cutter head driven by the reduction gearbox, wherein the reduction gearbox is disposed on the mounting block.

[0011] By adopting the above technical solution, the chamfering machine can automatically chamfer chain reels. A drive motor provides power, which, after transmission through a gearbox, drives the cutter head to perform the cutting operation, thus replacing manual grinding. This ensures uniform chamfering, avoids chain jamming, extends chain life, and reduces production costs. The drive motor ensures stable cutter head operation, and the gearbox effectively controls the cutter head speed, guaranteeing processing accuracy. The cutter head directly blunts the sharp corners of the chain reel.

[0012] Preferably, the positioning mechanism includes multiple positioning blocks, threaded rods, clamping blocks, and clamping nuts disposed on the worktable. The positioning blocks have positioning grooves for engaging with the teeth of the chain disc. The clamping blocks have connecting holes through which the threaded rods pass. The clamping nuts are disposed on the side of the clamping blocks away from the worktable and are threadedly connected to the threaded rods. The clamping blocks are used to clamp the chain disc. The multiple positioning blocks and clamping blocks are all suitable for positioning chain discs of different sizes.

[0013] By adopting the above technical solution, the positioning groove on the positioning block can engage with the teeth of the chain disc, achieving initial positioning of the chain disc, and is suitable for chain discs of different sizes. The clamping block, through the cooperation of the threaded rod and the clamping nut, can adjust the clamping force to firmly fix the chain disc, further improving the stability of positioning. The design of multiple positioning blocks and clamping blocks ensures good adaptability of the equipment to chain discs of different sizes, effectively avoiding the problem of uneven chamfering caused by manual grinding, thereby reducing chain jamming, chain biting, and chain breakage, extending the service life of the chain and reducing production costs.

[0014] Preferably, the rotating mechanism includes a rotary drive device disposed on the base and a connecting shaft that is drively connected to the rotary drive device, the connecting shaft being connected to the worktable.

[0015] By adopting the above technical solution, the rotary drive device can drive the connecting shaft to rotate, thereby driving the worktable to rotate. This design allows the chain to rotate omnidirectionally during the chamfering process, ensuring that the cutting head mechanism can perform uniform chamfering on different positions of the chain, effectively avoiding the problem of uneven chamfering caused by manual operation, thus preventing chain jamming and chain biting, and improving the processing quality and service life of the chain.

[0016] Preferably, a reinforcing bracket is provided below the workbench. The reinforcing bracket includes a first support ring located at the center of the bottom of the workbench, a second support ring located at the outer edge of the bottom of the workbench, and a plurality of reinforcing rods located at the bottom of the workbench. The first support ring is located outside the connecting shaft. One end of each reinforcing rod is connected to the first support ring, and the other end is connected to the second support ring. The plurality of reinforcing rods are distributed radially.

[0017] By adopting the above technical solution, a first support ring and a second support ring are set at the bottom of the worktable, and connected by multiple radially distributed reinforcing rods, which effectively enhances the overall structural strength of the worktable and improves its load-bearing capacity. This design ensures that the worktable remains stable when the chain conveyor is carrying out chamfering, avoiding processing errors caused by vibration or uneven force, thereby improving the accuracy and quality of chamfering.

[0018] Preferably, the base is provided with a limiting support frame, which includes a plurality of second support rods, a connecting rod disposed on the top of the second support rods, a limiting sleeve and a limiting ring. The limiting sleeve is disposed on the outside of the connecting rod, the connecting rod is rotatably connected to the limiting sleeve, one end of the connecting rod is connected to the limiting sleeve, and the other end is connected to the limiting ring. The limiting ring is disposed on the outside of the worktable and the second support ring.

[0019] By adopting the above technical solution, the setting of the limiting support frame can improve the stability of the worktable and prevent the worktable from shifting due to vibration during processing. The combined use of multiple second support rods with limiting sleeves and limiting rings further enhances the support and limiting effect on the worktable, ensuring that the worktable remains stable when rotating, thereby improving the accuracy of chamfering.

[0020] Preferably, the mounting block is provided with a protective cover, the protective cover including a mounting tube and a rubber protective strip disposed on the mounting tube.

[0021] By adopting the above technical solution, the protective cover can effectively reduce the splashing of metal debris generated by the cutter head mechanism during operation, protecting the safety of operators. The mounting tube, as the main structure of the protective cover, serves to fix and support the rubber protective strip.

[0022] In summary, this application has the following beneficial technical effects:

[0023] 1. By adjusting the position of the cutter head mechanism through the adjustment mechanism, and combining it with the rotation mechanism to drive the worktable and chain wheel to rotate, it is possible to achieve chamfering of chain wheels of different sizes, which significantly improves the applicability and flexibility of the equipment;

[0024] 2. The positioning block and clamping block in the positioning mechanism can be adapted to various sizes of chain discs, ensuring stable positioning of the chain discs during processing, avoiding processing deviations, and improving the uniformity of chamfering;

[0025] 3. Automated chamfering replaces manual operation, reducing quality problems caused by human factors, effectively reducing production costs and extending the service life of the chain conveyor. Attached Figure Description
