Description

Technical Field

[0001] This utility model belongs to the field of flange processing technology, and in particular relates to a flange chamfering device. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts to each other. It is used for connecting pipe ends, and also for connecting two pieces of equipment, such as a speed reducer flange. Flanges need to be chamfered during the processing of flanges. However, existing flange chamfering devices still have some problems.

[0003] For example, the utility model patent with publication number CN222818062U includes a processing base, with a mounting bracket on top of the processing base and a motor mounted on the lower end of the processing base. The output shaft of the motor passes through the processing base and is fixedly connected to the lower end of the mounting bracket. A fixing plate is provided on top of the mounting bracket. This utility model uses a throttle to drive the threaded rod to rotate, thereby driving the retaining ring to clamp and fix the inner diameter of the flange. However, this fixing method is prone to loosening of the threaded rod due to vibration during the chamfering process, resulting in clamping failure and poor stability. Utility Model Content

[0004] The purpose of this invention is to provide a flange chamfering device. By setting clamping blocks, specifically by starting a second motor, a screw is driven to rotate through a worm gear and worm wheel transmission, thereby causing a slider to rise. Through the action of a connecting rod, the three clamping blocks clamp and fix the inner diameter of the flange. Due to the self-locking characteristics of the worm wheel and worm, clamping failure caused by vibration is effectively prevented, ensuring clamping stability. This solves the problem of existing flange chamfering devices that use threaded rods for clamping and fixing, which are prone to loosening due to vibration, resulting in clamping failure and poor stability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a flange chamfering device, comprising an operating table, a clamping platform rotatably connected to the top of the operating table, and a motor fixedly connected to the bottom of the operating table. The top output end of the motor is fixedly connected to the bottom of the clamping platform. The operating table also includes a clamping mechanism.

[0007] A clamping mechanism, mounted on the top of a clamping platform, is used to clamp and fix the flange. The clamping mechanism includes three clamping blocks, the bottom of which are slidably connected to the top of the clamping platform. A support plate is fixedly connected to the top of the clamping platform via support legs. A lead screw is rotatably connected to the bottom of the support plate. A slider is threaded onto the outer surface of the lead screw. Three connecting rods are rotatably connected to the top of the slider via pins. The side of each connecting rod away from the slider is rotatably connected to the side of the clamping block near the center via pins. The clamping mechanism also includes a driving mechanism.

[0008] A drive mechanism is installed inside the clamping table and is used to drive the lead screw to rotate and move the slider.

[0009] A chamfering assembly, installed on the top left side of the worktable, is used for chamfering flange plates;

[0010] A dust collection assembly is installed on the top right side of the operating table and is used to clean up metal debris generated during the chamfering process. After the flange is clamped and fixed by the clamping mechanism, the chamfering assembly is used to perform the chamfering operation, ensuring the stability of the flange during the chamfering process and improving the chamfering accuracy.

[0011] Furthermore, the driving mechanism includes a power chamber, which is fixedly connected inside the clamping table. A worm gear is rotatably connected to the inner wall of the bottom of the power chamber, and a worm is rotatably connected to the inner wall of the power chamber. The front of the worm meshes with the back of the worm gear. A second motor is fixedly connected to the inner wall of the bottom of the clamping table, and the left output end of the second motor is fixedly connected to the right side of the worm. Due to the self-locking characteristics of the worm gear and worm, the loosening of the threaded rod caused by processing vibration is effectively prevented, ensuring stable clamping.

[0012] Furthermore, the outer surface of each clamping block is provided with anti-slip texture. The anti-slip texture increases the friction with the contact surface of the flange, ensuring that the workpiece is firmly clamped during rotation and cutting, and is not easy to loosen or shift, thereby further improving the stability of clamping.

[0013] Furthermore, the clamping platform also includes a limiting mechanism:

[0014] The limiting mechanism includes three limiting grooves, which are formed on the top of the clamping platform. A slider is fixedly connected to the bottom of the clamping block. The outer surface of the slider is slidably connected to the inner wall of the groove. The slider cooperates with the limiting groove to provide a stable movement trajectory for the movement of the clamping block and avoid deviation or jamming during the movement of the clamping block.

[0015] Furthermore, the chamfering assembly includes a fixing block, the bottom of which is fixedly connected to the top left side of the operating table, and an electric push rod is fixedly connected to the top of the fixing block. A support block is fixedly connected to the right output end of the electric push rod. Two blades are provided on the right side of the electric support block. The electric push rod pushes the support block to move, so that the blades approach the flange to perform chamfering operations.

[0016] Furthermore, the chamfering assembly also includes a second limiting mechanism:

[0017] The second limiting mechanism includes two limiting rods. The left side of the limiting rod is fixedly connected to the right side of the fixing block. The front and back sides of the support block are fixedly connected to limiting blocks. The inside of the limiting block is slidably connected to the outer surface of the limiting rod. The sliding cooperation between the limiting rod and the limiting block provides guidance for the feed movement of the chamfering assembly and provides additional support, effectively preventing the support block and the cutting tool from swaying or vibrating, and ensuring the accuracy of the chamfering process.

[0018] Furthermore, the chamfering assembly also includes an adjustment component:

[0019] The adjustment assembly includes a slide groove located on the right side of the support block. A slider three is slidably connected to the inner wall of the slide groove. The left side of the lower blade is fixedly connected to the right side of the support block, and the left side of the upper blade is fixedly connected to the right side of the slider three. A lead screw two is rotatably connected inside the slide groove, and a worm gear two is fixedly connected to the top of the lead screw two. A worm gear two is rotatably connected to the left side of the support block through two support blocks. The right side of the worm gear two is meshed with the left side of the worm gear two. A knob is fixedly connected to the front of the worm gear two. By operating the knob, the position of the upper blade can be precisely and smoothly adjusted, thereby changing the distance between the two blades. This design facilitates quick adaptation to the chamfering requirements of flanges of different thicknesses, provides high adjustment accuracy, and has self-locking properties, reliably maintaining the set spacing.

[0020] Furthermore, the dust collection assembly includes a vacuum cleaner, the bottom of which is fixedly connected to the top right side of the operating table. Connecting pipes are fixedly connected to both the front and back of the vacuum cleaner. A suction port is fixedly connected to the side of the connecting pipe near the top of the clamping table. A filter screen is fixedly connected to the corresponding side of each of the two suction ports. The dual suction ports are symmetrically arranged on both sides of the clamping area, expanding the effective suction range and more effectively capturing debris generated by chamfering. The filter screen can prevent larger particles of debris from being sucked into the pipe, preventing blockage of the connecting pipe and the inside of the vacuum cleaner, and ensuring the long-term stable operation of the dust collection system.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model uses clamping blocks, specifically starting motor two, which drives screw one to rotate through worm gear and worm wheel transmission, thereby causing slider one to rise. Through the action of connecting rod, the three clamping blocks clamp and fix the inner diameter of the flange. Due to the self-locking characteristics of worm wheel and worm, clamping failure caused by processing vibration is effectively prevented, ensuring clamping stability.

[0023] 2. This utility model, by setting an adjustment component, specifically by rotating a knob, drives the lead screw to rotate through the worm gear and worm wheel, thereby causing the slider to move the upper blade to slide on the inner wall of the groove, thus adjusting the distance between the two blades. The adjustment is highly accurate and has self-locking properties, which can reliably maintain the set distance and adapt to flanges of different thicknesses.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0034] Please see Figures 1-5 As shown, this utility model has the following three specific embodiments.

[0035] Example 1

[0036] This utility model relates to a flange chamfering device, comprising an operating platform 1, a clamping platform 11 rotatably connected to the top of the operating platform 1, a motor 111 fixedly connected to the bottom of the operating platform 1, the top output end of the motor 111 being fixedly connected to the bottom of the clamping platform 11, and the operating platform 1 further comprising a clamping mechanism.

[0037] A clamping mechanism is mounted on the top of the clamping platform 11 for clamping and fixing the flange. The clamping mechanism includes three clamping blocks 12, the bottom of which is slidably connected to the top of the clamping platform 11. A support plate 125 is fixedly connected to the top of the clamping platform 11 via support legs. A lead screw 126 is rotatably connected to the bottom of the support plate 125. A slider 127 is threaded onto the outer surface of the lead screw 126. Three connecting rods 128 are rotatably connected to the top of the slider 127 via pins. The side of the connecting rods 128 away from the slider 127 is rotatably connected to the side of the clamping block 12 near the center via pins. The clamping mechanism also includes a drive mechanism.

[0038] The drive mechanism is installed inside the clamping table 11 and is used to drive the lead screw 126 to rotate and drive the slider 127 to move.

[0039] Chamfering assembly 2 is installed on the top left side of the worktable 1 and is used for chamfering the flange plate;

[0040] Dust collection component 3 is installed on the top right side of the workbench 1 and is used to clean up metal shavings generated during the chamfering process.

[0041] The drive mechanism includes a power chamber 121, which is fixedly connected inside the clamping table 11. A worm gear 122 is rotatably connected to the bottom inner wall of the power chamber 121, and a worm 123 is rotatably connected to the inner wall of the power chamber 121. The front of the worm 123 meshes with the back of the worm gear 122. A second motor 124 is fixedly connected to the bottom inner wall of the clamping table 11, and the left output end of the second motor 124 is fixedly connected to the right side of the worm 123.

[0042] The outer surface of the clamping block 12 is provided with anti-slip texture 129.

[0043] The clamping platform 11 also includes a limiting mechanism:

[0044] Limiting mechanism one includes three limiting grooves 13. The limiting grooves 13 are opened on the top of the clamping table 11. The bottom of the clamping block 12 is fixedly connected to the slider two 131. The outer surface of the slider two 131 is slidably connected to the inner wall of the limiting groove 13.

[0045] In this embodiment, as Figures 1-3 As shown, by setting the clamping blocks 12, specifically by starting the motor 124, the screw 126 is driven to rotate through the worm gear 123 and worm wheel 122, thereby causing the slider 127 to rise. Through the action of the connecting rod 128, the three clamping blocks 12 clamp and fix the inner diameter of the flange. Due to the self-locking characteristics of the worm wheel 122 and worm gear 123, clamping failure caused by vibration is effectively prevented, ensuring clamping stability. The anti-slip texture 129 increases the friction and further improves the clamping stability effect. The limiting groove 13 provides a stable movement trajectory for the movement of the clamping blocks 12, avoiding deviation or jamming during the movement of the clamping blocks 12.

[0046] Example 2

[0047] The difference from Embodiment 1 is that this embodiment discloses a limiting mechanism for the movement of the support block 221 and an adjusting component 23 for adjusting the distance between the two blades 222:

[0048] The chamfering assembly 2 includes a fixing block 21. The bottom of the fixing block 21 is fixedly connected to the top left side of the operating table 1. An electric push rod 22 is fixedly connected to the top of the fixing block 21. A support block 221 is fixedly connected to the right output end of the electric push rod 22. Two blades 222 are provided on the right side of the support block 221.

[0049] Chamfering component 2 also includes adjustment component 23:

[0050] Adjustment component 23 includes a slide groove 231, which is located on the right side of support block 221. A slider 232 is slidably connected to the inner wall of slide groove 231. The left side of the lower blade 222 is fixedly connected to the right side of support block 221, and the left side of the upper blade 222 is fixedly connected to the right side of slider 232. A lead screw 233 is rotatably connected inside slide groove 231. A worm gear 234 is fixedly connected to the top of lead screw 233. A worm gear 235 is rotatably connected to the left side of support block 221 through two support blocks. The right side of worm gear 235 is meshed with the left side of worm gear 234. A knob 236 is fixedly connected to the front of worm gear 235.

[0051] In this embodiment, as Figure 4 As shown, by setting the adjustment component 23, specifically by rotating the knob 236, the worm gear 235 and worm wheel 234 drive the lead screw 233 to rotate, thereby causing the slider 232 to drive the upper blade 222 to slide on the inner wall of the groove 231, thereby adjusting the distance between the two blades 222. The adjustment is highly accurate and has self-locking properties, which can reliably maintain the set distance and adapt to flanges of different thicknesses.

[0052] Example 3

[0053] The difference from Embodiment 2 is that this embodiment discloses how the dust collection component 3 completes the dust collection operation:

[0054] The dust collection assembly 3 includes a vacuum cleaner 31. The bottom of the vacuum cleaner 31 is fixedly connected to the top right side of the operating table 1. A connecting pipe 311 is fixedly connected to both the front and back of the vacuum cleaner 31. A suction port 32 is fixedly connected to the side of the connecting pipe 311 near the top of the clamping table 11. A filter screen 321 is fixedly connected to the corresponding side of the two suction ports 32.

[0055] In this embodiment, if Figure 5 As shown, the suction port 32 effectively captures debris generated by the chamfer. The filter screen inside the suction port 32 prevents larger debris particles from being sucked into the pipe, preventing blockage of the connecting pipe 311 and the inside of the vacuum cleaner 31, and ensuring the long-term stable operation of the dust collection system.

[0056] A specific application of this embodiment is as follows: During use, the flange is placed on top of the clamping platform 11. The motor 124 is started, and the screw 126 rotates via the worm gear 123 and worm wheel 122, causing the slider 127 to rise. Through the connecting rod 128, the three clamping blocks 12 clamp and fix the inner diameter of the flange. Due to the self-locking characteristics of the worm wheel 122 and worm gear 123, clamping failure caused by vibration is effectively prevented, ensuring clamping stability. The anti-slip texture 129 increases the friction with the flange contact surface, further ensuring clamping stability and preventing slippage during the chamfering process. While the clamping blocks 12 move, the slider 131 slides on the inner wall of the limiting groove 13. The limiting groove 13 provides a stable movement trajectory for the clamping blocks 12, preventing them from shifting or jamming during clamping or releasing. Adjust the distance between the two blades 222 according to the flange thickness. Turn the knob 236 to drive the lead screw 233 to rotate through the worm gear 235 and worm wheel 234. This causes the slider 3 232 to drive the blade 222 located above to slide on the inner wall of the groove 231, thereby adjusting the distance between the two blades 222 to adapt to flanges of different thicknesses. Then, start the electric push rod 22 to push the blade 222 closer to the flange. Start the motor 111 to drive the clamping table 11 to rotate for chamfering. While the two blades 222 are moving, the limiting block 224 slides on the outer surface of the limiting rod 223. The limiting block 224 and the limiting rod 223 provide a stable motion trajectory for the blade 222 and provide additional support, effectively preventing the support block and blade from swaying or vibrating, and ensuring the accuracy of the chamfering process.
