Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chamfering tool processing equipment, and in particular to a fixing structure for processing equilateral triangular chamfering tools. Background Technology
[0002] The function of a triangular chamfering tool is to machine a chamfer with an equilateral triangular cross-section on the edge of a workpiece (such as the edge of a part, the opening of a hole, etc.). During machining, it is necessary to ensure that the workpiece is in a stable position to avoid deviations in chamfer dimensions or irregular shapes due to vibration or displacement.
[0003] Currently, existing fixing structures often use multiple screws for fixation, which results in insufficient stability. This is because screw fixation relies on thread friction, and under high-speed rotation or vibration environments, the threads are prone to fatigue wear and loosening, causing gaps between the chamfering tool and the drive shaft. This leads to eccentric vibration during processing, resulting in angular deviations in the equilateral triangular chamfer and excessively high surface roughness. At the same time, the fixing and disassembly process is relatively cumbersome, which is not conducive to quick replacement of the chamfering tool and reduces processing efficiency. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a fixing structure for machining a right-angled triangular chamfering tool.
[0005] This utility model is achieved using the following technical solution: a fixing structure for machining a right-angled triangular chamfering tool, comprising a drive shaft, a mounting hole at the bottom end of the drive shaft, a chamfering tool inserted into the mounting hole, a fixing component on the drive shaft for quickly fixing the chamfering tool, a limiting component on the drive shaft to prevent the fixing component from loosening, the fixing component comprising a first fixing plate disposed on one side of the drive shaft, a fixing post fixedly mounted on one side of the first fixing plate, one end of the fixing post penetrating the drive shaft and the chamfering tool and extending to the outside of the drive shaft, and a second fixing plate slidably mounted on the end of the fixing post located on the outside of the drive shaft.
[0006] Through the above technical solution, the fixing component can quickly fix the chamfering tool. After the fixing post passes through the drive shaft and the chamfering tool, it works with the first fixing plate and the second fixing plate to clamp the drive shaft from both sides, which can firmly fix the chamfering tool on the drive shaft. The limiting component can further prevent the fixing component from loosening during the processing, ensuring the reliability of the fixation, thereby improving the processing accuracy and efficiency.
[0007] As a further improvement to the above solution, the opposing surfaces of the first fixing plate and the second fixing plate are both in contact with the cylindrical surface of the drive shaft.
[0008] The above technical solution enables the first and second fixing plates to better fit with the drive shaft, increasing the contact area and improving the clamping stability of the drive shaft and chamfering tool, thus avoiding shaking during processing due to loose fit.
[0009] As a further improvement to the above solution, a plurality of stabilizing columns are fixedly installed on one side of the first fixing plate, and one end of each stabilizing column passes through the drive shaft, the chamfering tool, and the second fixing plate.
[0010] Through the above technical solution, the stabilizing column can assist the fixing column in further enhancing the fixing effect. The even distribution of multiple stabilizing columns can make the fixing force on the chamfering tool more uniform, prevent the chamfering tool from deflecting during processing, and further ensure the stability and accuracy of processing.
[0011] As a further improvement to the above solution, the limiting component includes a limiting sleeve that is slidably sleeved on the drive shaft. Two limiting grooves are symmetrically opened on the bottom inner wall of the limiting sleeve, and the first fixing plate and the second fixing plate are both located inside the adjacent limiting grooves.
[0012] Through the above technical solution, the limiting sleeve limits the first fixing plate and the second fixing plate through the limiting groove, preventing the first fixing plate and the second fixing plate from moving during the processing, thereby avoiding the loosening of the fixing column and the stabilizing column and ensuring the fixing effect of the fixing component.
[0013] As a further improvement to the above solution, a limiting ring is fixedly sleeved on the drive shaft, and a plurality of limiting rods arranged in a circular array are fixedly installed on the top of the limiting ring. The top of each limiting rod passes through the limiting ring upward and is fixedly installed with a limiting block.
[0014] Through the above technical solution, the limiting ring plays a limiting role for the limiting sleeve, the limiting rod passes through the limiting ring and prevents the limiting sleeve from falling off the drive shaft through the limiting block, ensuring that the limiting sleeve can continuously limit the fixed component. At the same time, multiple limiting rods arranged in a ring array make the limiting sleeve uniformly stressed, improving the stability of the limiting.
[0015] As a further improvement to the above solution, each of the limiting rods is fitted with a spring, and both ends of each spring abut against the limiting sleeve and the limiting ring, respectively.
[0016] With the above technical solution, the spring is in a compressed state, which can generate a downward elastic force on the limiting sleeve, so that the limiting sleeve fits tightly against the first fixing plate and the second fixing plate, enhancing the limiting effect of the limiting sleeve on the fixing component and effectively preventing the fixing component from loosening due to vibration or other reasons during the processing.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention, by setting up a fixing component and a limiting component, uses a fixing column and a stabilizing column in the fixing component, together with a first fixing plate and a second fixing plate, to quickly and securely fix the equilateral triangular chamfering tool on the drive shaft. The installation and disassembly process is simple and facilitates quick replacement of the chamfering tool. The limiting component, through the limiting sleeve, limiting rod, spring and other structures, effectively prevents the fixing component from loosening during processing, ensuring the reliability of the fixation.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Please combine Figures 1-4 A fixing structure for machining a right triangle chamfering tool according to this embodiment includes a drive shaft 1, a mounting hole at the bottom end of the drive shaft 1, a chamfering tool 2 inserted into the mounting hole, a fixing component on the drive shaft 1 that can quickly fix the chamfering tool 2, and a limiting component on the drive shaft 1 that can prevent the fixing component from loosening.
[0027] The fixing assembly includes a first fixing plate 301 disposed on one side of the drive shaft 1. A fixing post 302 is fixedly installed on one side of the first fixing plate 301. One end of the fixing post 302 passes through the drive shaft 1 and the chamfering tool 2 and extends to the outside of the drive shaft 1. A second fixing plate 303 is slidably sleeved on the end of the fixing post 302 located on the outside of the drive shaft 1. The fixing assembly can achieve quick fixing of the chamfering tool 2. After the fixing post 302 passes through the drive shaft 1 and the chamfering tool 2, it clamps the drive shaft 1 from both sides in conjunction with the first fixing plate 301 and the second fixing plate 303. Shaft 1 securely fixes the chamfering tool 2 onto the drive shaft 1; the limiting component further prevents the fixing component from loosening during processing, ensuring the reliability of the fixation, thereby improving processing accuracy and efficiency. The opposing surfaces of the first fixing plate 301 and the second fixing plate 303 are both in contact with the cylindrical surface of the drive shaft 1. The first fixing plate 301 and the second fixing plate 303 can better fit with the drive shaft 1, increasing the contact area and improving the clamping stability of the drive shaft 1 and the chamfering tool 2, avoiding shaking due to loose fit during processing.
[0028] Multiple stabilizing posts 5 are fixedly installed on one side of the first fixing plate 301. One end of each stabilizing post 5 passes through the drive shaft 1, the chamfering cutter 2, and the second fixing plate 303. The stabilizing posts 5 can assist the fixing posts 302 in further enhancing the fixing effect. The multiple stabilizing posts 5 are evenly distributed, which can make the fixing force on the chamfering cutter 2 more uniform, prevent the chamfering cutter 2 from deflecting during the processing, and further ensure the stability and accuracy of the processing.
[0029] The limiting assembly includes a limiting sleeve 401 slidably fitted onto the drive shaft 1. Two limiting grooves are symmetrically formed on the inner bottom wall of the limiting sleeve 401. The first fixing plate 301 and the second fixing plate 303 are both located inside adjacent limiting grooves. The limiting sleeve 401 limits the first fixing plate 301 and the second fixing plate 303 through the limiting grooves, preventing them from moving during processing. This avoids loosening of the fixing post 302 and the stabilizing post 5, ensuring the fixing effect of the assembly. A limiting ring 402 is fixedly fitted onto the drive shaft 1. Multiple limiting rods 403 arranged in a circular array are fixedly installed on the top of the limiting sleeve 401. The top of each limiting rod 403 passes upward through the limiting ring 402 and is fixedly fitted with a limiting block 404. The limiting ring 402 limits the limiting sleeve... 401 serves as a limit, with the limit rod 403 passing through the limit ring 402 and the limit block 404 to prevent the limit sleeve 401 from falling off the drive shaft 1, ensuring that the limit sleeve 401 can continuously limit the fixed component. At the same time, multiple limit rods 403 arranged in a ring array make the limit sleeve 401 evenly stressed, improving the stability of the limit. Each limit rod 403 is fitted with a spring 405, and both ends of each spring 405 abut against the limit sleeve 401 and the limit ring 402 respectively. When the spring 405 is in the unfolded state, it can generate a downward limiting force on the limit sleeve 401, making the limit sleeve 401 tightly fit the first fixed plate 301 and the second fixed plate 303, enhancing the limiting effect of the limit sleeve 401 on the fixed component, and effectively preventing the fixed component from loosening due to vibration or other reasons during processing.
[0030] The implementation principle of a fixing structure for machining a right-angled triangular chamfering tool in this application embodiment is as follows: when installing the right-angled triangular chamfering tool 2, the chamfering tool 2 is first inserted into the mounting hole at the bottom of the drive shaft 1, so that the corresponding hole on the chamfering tool 2 is aligned with the hole on the drive shaft 1.
[0031] Then, the fixing post 302 and the stabilizing post 5 on one side of the first fixing plate 301 are passed through the holes on the drive shaft 1 and the chamfering tool 2, so that one end of the fixing post 302 and the stabilizing post 5 extends to the outside of the drive shaft 1. Then, the second fixing plate 303 is slidably sleeved on the end of the fixing post 302 and the stabilizing post 5 located on the outside of the drive shaft 1, so that the opposite surfaces of the first fixing plate 301 and the second fixing plate 303 are in contact with the cylindrical surface of the drive shaft 1, thus completing the initial fixing of the chamfering tool 2.
[0032] Next, the sliding limiting sleeve 401 is slidable so that the first fixing plate 301 and the second fixing plate 303 are respectively located in the two limiting grooves on the bottom inner wall of the limiting sleeve 401. At this time, the limiting rod 403 at the top of the limiting sleeve 401 passes through the limiting ring 402, and the spring 405 on the limiting rod 403 is in the unfolded state. Under the elastic force of the spring 405, the limiting sleeve 401 tightly fits the first fixing plate 301 and the second fixing plate 303, limiting them and preventing the first fixing plate 301 and the second fixing plate 303 from moving, thereby preventing the fixing post 302 and the stabilizing post 5 from loosening, and realizing the stable fixation of the chamfering knife 2.
[0033] When it is necessary to disassemble or replace the chamfering cutter 2, pull the limiting block 404 upward, which will drive the limiting rod 403 and the limiting sleeve 401 to move upward, so that the limiting sleeve 401 is separated from the first fixing plate 301 and the second fixing plate 303. Then, remove the second fixing plate 303 from the fixing post 302 and the stabilizing post 5, and then pull out the fixing post 302 and the stabilizing post 5. The chamfering cutter 2 can then be taken out from the mounting hole of the drive shaft 1. The operation is simple and quick.
[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
