[0031] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the features in the following embodiments can be combined with each other.

[0032] Please refer to Figures 1 to 3 , an embodiment of the present invention provides a bar chamfering device 100 for chamfering a bar 200. It can effectively improve the chamfering efficiency, reduce the labor cost and time cost, avoid the backlog of the bar 200, and can enhance the chamfering effect, improve the product quality, and is safe and reliable.

[0033] The bar chamfering device 100 includes a frame 110, a chamfering mechanism 120, a first feeding mechanism 130, a second feeding mechanism 140, and a stop mechanism 150. Among them, the chamfering mechanism 120, the first feeding mechanism 130, the second feeding mechanism 140, and the stop mechanism 150 are all installed on the frame 110; the first feeding mechanism 130 and the second feeding mechanism 140 are oppositely arranged on both sides of the chamfering mechanism 120. The first feeding mechanism 130 is used to feed the bar 200 into the chamfering mechanism 120 and fix the position of the bar 200, and the second feeding mechanism 140 is used to send the bar 200 outwards and fix the position of the bar 200; the stop mechanism 150 is used to limit the bar 200 to ensure that the position of the end of the bar 200 corresponds to the position of the chamfering mechanism 120; the chamfering mechanism 120 is used to chamfer the end of the bar 200 to eliminate quality defects such as burrs, flash, sharp edges, and swelling at the end of the bar 200.

[0034] The chamfering mechanism 120 includes a bearing plate 121, a first driving motor 122, a transmission assembly 123, a rotating ring 124, a chamfering assembly 125, a limiting frame 126, a lifting member 127 and a translation member 128. The bearing plate 121 is provided with a receiving hole 1211, and the rotating ring 124 is rotatably disposed in the receiving hole 1211, and the rotating ring 124 can rotate relative to the bearing plate 121. The middle part of the rotating ring 124 has a relief hole 1241 for the bar 200 to pass through, so as to facilitate the chamfering and conveying of the bar 200. The first driving motor 122 is mounted on the bearing plate 121 and connected to the rotating ring 124 through the transmission assembly 123. The first driving motor 122 is used to drive the rotating ring 124 to rotate relative to the bearing plate 121. The chamfering assembly 125 is mounted on the rotating ring 124, and the position of the chamfering assembly 125 corresponds to the position of the end of the bar 200. The chamfering assembly 125 is used to chamfer the end of the bar 200 while the first driving motor 122 drives the rotating ring 124 to rotate, so as to achieve uniform chamfering of the entire circumference of the bar 200. Specifically, when the bar 200 passes through the relief hole 1241 and moves to a preset position, the position of the chamfering assembly 125 corresponds to the position of the end of the bar 200. At this time, the chamfering assembly 125 is started to chamfer the end of the bar 200. At the same time, the first driving motor 122 is started to drive the chamfering assembly 125 to rotate around the bar 200 for one week through the rotating ring 124, so that the chamfering assembly 125 chamfers the entire circumference of the end of the bar 200 once. In this way, the chamfering efficiency is effectively improved, the labor cost and time cost are reduced, the situation of bar 200 backlog is avoided, and the chamfering effect can be enhanced, the product quality is improved, and it is safe and reliable.

[0035] Further, a bearing 129 is sleeved outside the rotating ring 124, and the bearing 129 is embedded in the receiving hole 1211 to realize the rotation function of the rotating ring 124 in the receiving hole 1211. During the rotation of the rotating ring 124 relative to the bearing plate 121, the bearing 129 can limit the rotating ring 124 to improve the rotation stability of the rotating ring 124.

[0036] It should be noted that the bearing plate 121 is disposed within the limit frame 126 and is in sliding fit with the limit frame 126. The bearing plate 121 can slide relative to the limit frame 126, and the limit frame 126 can limit and guide the bearing plate 121. The lifting member 127 is installed on the limit frame 126 and is connected to the bearing plate 121. The lifting member 127 is used to drive the bearing plate 121 to rise or fall along the first direction, so as to adjust the height of the bearing plate 121 in the first direction, and thus adjust the height of the chamfering assembly 125 in the first direction, ensuring that the chamfering assembly 125 can maintain a state of being in contact with the bar 200 during the rotation of the rotating ring 124, thereby realizing the chamfering operation on the bar 200. The translation member 128 is installed on the frame 110 and is connected to the limit frame 126. The translation member 128 is used to drive the bearing plate 121 to translate along the second direction through the limit frame 126, so as to adjust the position of the bearing plate 121 in the second direction, and thus adjust the position of the chamfering assembly 125 in the second direction, ensuring that the chamfering assembly 125 can maintain a state of being in contact with the bar 200 during the rotation of the rotating ring 124, thereby realizing the chamfering operation on the bar 200.

[0037] Specifically, the second direction is perpendicular to the first direction. Under the action of the lifting member 127 and the translation member 128, the chamfering assembly 125 can move to any coordinate on the plane where the bearing plate 121 is located, so as to facilitate the adjustment of the position of the chamfering assembly 125, improve the chamfering accuracy, and ensure the chamfering quality. In this embodiment, the first direction is the vertical direction, and the second direction is the horizontal direction. The lifting member 127 can drive the chamfering assembly 125 to rise and fall along the vertical direction through the bearing plate 121 and the rotating ring 124, and the translation member 128 can drive the chamfering assembly 125 to translate along the horizontal direction through the limit frame 126, the bearing plate 121 and the rotating ring 124.

[0038] In this embodiment, a return spring 1261 is arranged inside the limit frame 126. The return spring 1261 is located on the side of the bearing plate 121 away from the lifting member 127. One end of the return spring 1261 is connected to the bearing plate 121, and the other end is connected to the limit frame 126. The return spring 1261 is used to apply an elastic force to the bearing plate 121 to achieve the rapid reset function of the bearing plate 121. Specifically, the lifting member 127 is arranged above the bearing plate 121, and the return spring 1261 is arranged below the bearing plate 121. The number of the return springs 1261 is two, and the two return springs 1261 are arranged side by side. When the lifting member 127 drives the bearing plate 121 to rise, the return spring 1261 is stretched. At this time, the return spring 1261 applies a downward elastic force to the bearing plate 121 to drive the bearing plate 121 to descend stably when the lifting member 127 resets, improving the stability of the movement of the bearing plate 121. When the lifting member 127 drives the bearing plate 121 to descend, the return spring 1261 is compressed. At this time, the return spring 1261 applies an upward elastic force to the bearing plate 121 to drive the bearing plate 121 to rise stably when the lifting member 127 resets, improving the stability of the movement of the bearing plate 121.

[0039] Please refer to Figure 4 , the chamfering assembly 125 includes a second driving motor 1251, a transmission shaft 1252 and a grinding wheel 1253. The second driving motor 1251 is installed on the rotating ring 124 and is connected to the grinding wheel 1253 through the transmission shaft 1252. The transmission shaft 1252 passes through the rotating ring 124 and can rotate relative to the rotating ring 124. The grinding wheel 1253 is used to chamfer the bar 200. Specifically, during the process of chamfering the bar 200 along its circumferential direction, the first driving motor 122 drives the rotating ring 124 to rotate through the transmission assembly 123, so as to drive the grinding wheel 1253 to revolve around the bar 200 through the second driving motor 1251. At the same time, the second driving motor 1251 drives the grinding wheel 1253 to rotate by itself through the transmission shaft 1252. In this way, the grinding wheel 1253 rotates and revolves at the same time to chamfer the bar 200 along its circumferential direction, thereby realizing uniform chamfering of the entire circumference of the bar 200 and improving the product quality.

[0040] It is worth noting that in the process of chamfering the rod 200, the lifting member 127 and the translation member 128 are first reset to the initial position; then the rod 200 passes through the clearance hole 1241, is transported to the preset position, and is fixed. At this time, the rod 200 is coaxially arranged with the clearance hole 1241, and the position of the end of the rod 200 corresponds to the position of the grinding wheel 1253; then the chamfering assembly 125 is used to chamfer the end of the rod 200. During this process, if the diameter of the rod 200 matches the diameter of the grinding wheel 1253, that is, the grinding wheel 1253 can just grind the rod 200, there is no need to start the lifting member 127 and the translation member 128, and the entire circumference of the rod 200 can be uniformly chamfered only by the first drive motor 122 and the second drive motor 1251; if the diameter of the rod 200 does not match the diameter of the grinding wheel 1253, that is, there is a certain distance between the grinding wheel 1253 and the rod 200, it is necessary to use the lifting member 127 and the translation member 128 to adjust the position of the grinding wheel 1253 in real time while starting the first drive motor 122 and the second drive motor 1251, so as to achieve uniform chamfering of the entire circumference of the rod 200 and ensure the chamfering accuracy.

[0041] The grinding wheel 1253 includes a wheel body 1254 and a grinding ring 1255. The grinding ring 1255 is arranged on the circumference of the wheel body 1254, and the grinding ring 1255 is arranged in the middle of the wheel body 1254. The wheel body 1254 and the grinding ring 1255 are integrally formed. The cross section of the grinding ring 1255 is V-shaped, and the grinding ring 1255 is relatively provided with a first grinding surface 1256 and a second grinding surface 1257, and the first grinding surface 1256 and the second grinding surface 1257 are both used for grinding processing. Specifically, the first grinding surface 1256 is used to chamfer the end of a rod 200, and the second grinding surface 1257 is used to chamfer the end of another rod 200. The first grinding surface 1256 and the second grinding surface 1257 work together to further improve the chamfering efficiency and reduce the time cost.

[0042] Please continue to refer to Figure 3 The transmission assembly 123 includes a driving gear 1231, a driven gear 1232 and a transition gear 1233, and an annular rack 1242 is provided around the circumference of the rotating ring 124. The first driving motor 122 is connected to the driving gear 1231, and the first driving motor 122 can drive the driving gear 1231 to rotate. The driving gear 1231 is meshed with the transition gear 1233 through the driven gear 1232, and the driving gear 1231 can drive the transition gear 1233 to rotate through the driven gear 1232. The transition gear 1233 is meshed with the annular rack 1242, and the transition gear 1233 can drive the annular rack 1242 to rotate, thereby driving the rotating ring 124 to rotate relative to the bearing plate 121, and then driving the chamfering assembly 125 installed on the rotating ring 124 to rotate.

[0043] In this embodiment, there are two driven gears 1232 and transition gears 1233, and the two driven gears 1232 are arranged on both sides of the driving gear 1231. Each driven gear 1232 is meshed with a transition gear 1233, and the two transition gears 1233 are meshed with the annular rack 1242. In this way, the torque output by the first driving motor 122 can be more efficiently transmitted to the annular rack 1242, effectively improving the rotation efficiency of the rotating ring 124.

[0044] Please refer to Figure 5 The first feeding mechanism 130 includes a mounting frame 131, a feeding assembly 132, a first driving member 133 and a pressing block 134. The mounting frame 131 is connected to the frame 110, and the frame 110 is used to carry the mounting frame 131 and fix the position of the mounting frame 131. The feeding assembly 132 is installed on the mounting frame 131, and the feeding assembly 132 is used to feed the bar 200 so that the bar 200 extends into the chamfering mechanism 120. The first driving member 133 is installed on the mounting frame 131 and connected to the pressing block 134. The first driving member 133 is used to drive the pressing block 134 to press the bar 200 on the feeding assembly 132 when the feeding assembly 132 sends the bar 200 to the preset position, so as to prevent the bar 200 from continuing to move. At this time, the feeding assembly 132 is suspended, so that the chamfering mechanism 120 can chamfer the bar 200.

[0045] In this embodiment, the mounting frame 131 is connected to the frame 110 via a lifting cylinder (not shown), which can drive the mounting frame 131 to rise or fall to adjust the height of the mounting frame 131, thereby adjusting the height of the rod 200 transported by the feeding assembly 132, thereby ensuring that the axis of the rod 200 is colinear with the center line of the clearance hole 1241 (when the lifting member 127 and the translation member 128 are reset), which is convenient for subsequent chamfering operations.

[0046] The feeding assembly 132 includes a first feeding roller 1321 and a second feeding roller 1322. The first feeding roller 1321 and the second feeding roller 1322 are arranged in a V shape, and the rod 200 is placed between the first feeding roller 1321 and the second feeding roller 1322. The first feeding roller 1321 and the second feeding roller 1322 are used to synchronously feed the rod 200, and the first driving member 133 is used to simultaneously press the rod 200 on the first feeding roller 1321 and the second feeding roller 1322 through the pressing block 134. Specifically, the first feeding roller 1321 and the second feeding roller 1322 work together to limit the rod 200 and prevent the rod 200 from rolling, thereby facilitating transportation and compaction. In addition, the first feeding roller 1321 and the second feeding roller 1322 arranged in a V-shape can transport rods 200 of different diameters, which has a wide range of applications and is convenient and practical.

[0047] In this embodiment, the specific structure of the second feeding mechanism 140 is the same as the specific structure of the first feeding mechanism 130, and will not be repeated here.

[0048] Please continue to refer to Figure 1 and Figure 2 The stop mechanism 150 includes a second driving member 151, a slide 152 and a stop head 153. The frame 110 is provided with a slide slot 111, the second driving member 151 is mounted on the frame 110 and connected to the slide 152, the stop head 153 is mounted on the slide 152, the slide 152 is slidably matched with the slide slot 111, the second driving member 151 is used to drive the slide 152 to slide relative to the slide slot 111, and the stop head 153 is used to abut against the end of the rod 200. Specifically, the stop head 153 is hemispherical, and the midline of the bottom surface of the hemispherical shape of the stop head 153 is colinear with the center line of the clearance hole 1241 (when the lifting member 127 and the translation member 128 are reset) to ensure that the stop head 153 can stop the center of the end of the rod 200, improve the force effect, ensure the stopping effect, and the stop head 153 contacts the end of the rod 200 through the spherical surface to avoid scratching the rod 200.

[0049] Furthermore, before the first feeding mechanism 130 feeds the rod 200 into the chamfering mechanism 120, the second driving member 151 is started to drive the stopper head 153 to move to a position corresponding to the chamfering mechanism 120 through the slide 152; when the first feeding mechanism 130 feeds the rod 200 into the chamfering mechanism 120, the stopper head 153 can stop the rod 200 to ensure that the rod 200 stops at a preset position to prevent the rod 200 from being inertial. The rod 200 is pushed away from the preset position under the action; then the first driving member 133 presses the rod 200 through the clamping block 134 to fix the position of the rod 200 and prevent the rod 200 from moving; then the second driving member 151 is controlled to drive the stop head 153 to reset through the slide 152. At this time, the stop head 153 no longer stops the rod 200, so as to make way for the chamfering component 125, so that the chamfering component 125 can evenly chamfer the entire circumference of the rod 200.

[0050] In this embodiment, the lifting member 127, the translation member 128, the first driving member 133 and the second driving member 151 are all electric cylinders, but are not limited to this. In other embodiments, the lifting member 127, the translation member 128, the first driving member 133 and the second driving member 151 may all be pneumatic cylinders or hydraulic cylinders.

[0051] Please refer to Figure 6It is worth noting that during the use of the bar chamfering device 100, the stop mechanism 150 is first controlled to move to a position corresponding to the chamfering mechanism 120; the feeding assembly 132 of the first feeding mechanism 130 is then used to feed the bar 200 forward, so that the bar 200 passes through the clearance hole 1241 and abuts against the stop mechanism 150. At this time, the stop mechanism 150 limits the bar 200 so that the bar 200 stops at a preset position; then the first driving member 133 of the first feeding mechanism 130 is used to drive the pressing block 134 to press the bar 200 to prevent the bar 200 from moving; then the stop mechanism 150 is controlled to reset to prevent the stop mechanism 150 from interfering with the chamfering assembly 125; then the first driving member 133 of the first feeding mechanism 130 is started. The first drive motor 122 and the second drive motor 1251 are driven to make the grinding wheel 1253 revolve around the rod 200 while rotating, and the position of the grinding wheel 1253 is adjusted in real time by the lifting member 127 and the translation member 128 to achieve uniform chamfering of the entire circumference of the rod 200. During this process, the head end of the rod 200 is always in contact with the first grinding surface 1256 of the grinding wheel 1253, and the grinding wheel 1253 grinds and chamfers the head end of the rod 200 through the first grinding surface 1256. After one round of chamfering is completed, the first drive motor 122 and the second drive motor 1251 are paused, and the lifting member 127 and the translation member 128 are controlled to reset. Then, the first drive member 133 of the first feeding mechanism 130 is controlled to release the rod 200. The feeding assembly 132 of the first feeding mechanism 130 is used to continue to feed the rod 200 forward. During this process, the rod 200 extends into the second feeding mechanism 140. The feeding assembly 132 of the second feeding mechanism 140 drives the rod 200 to completely separate from the first feeding mechanism 130 and leave the position corresponding to the stop mechanism 150 to prevent the rod 200 from interfering with the movement of the stop mechanism 150. Then the stop mechanism 150 is controlled to move again to the position corresponding to the chamfering mechanism 120. The feeding assembly 132 of the first feeding mechanism 130 is used to feed the second rod 200 forward, so that the second rod 200 passes through the clearance hole 1241 and abuts against the stop mechanism 150. At this time, the stop mechanism 150 The two rods 200 are limited so that the second rod 200 stops at the preset position; then the first driving member 133 of the first feeding mechanism 130 drives the pressing block 134 to press the second rod 200 to prevent the second rod 200 from moving; then the stop mechanism 150 is controlled to reset to prevent the stop mechanism 150 from interfering with the chamfering assembly 125; then the feeding assembly 132 of the second feeding mechanism 140 is controlled to drive the previous rod 200 to retreat until the position of the tail end of the rod 200 corresponds to the position of the second grinding surface 1257; then the first driving member 133 of the second feeding mechanism 140 drives the pressing block 134 to press the previous rod 200 to prevent the previous rod 200 from moving;Then, start the first driving motor 122 and the second driving motor 1251 to make the grinding wheel 1253 revolve around the bar 200 while rotating itself, and adjust the position of the grinding wheel 1253 in real time through the lifting member 127 and the translation member 128, so as to simultaneously achieve uniform chamfering of the entire circumference of two bars 200. During this process, the tail end of the previous bar 200 is always in contact with the second grinding surface 1257 of the grinding wheel 1253, and the head end of the second bar 200 is always in contact with the first grinding surface 1256 of the grinding wheel 1253. The grinding wheel 1253 chamfers the ends of the two bars 200 through the first grinding surface 1256 and the second grinding surface 1257 at the same time; cycle in this way to continuously chamfer the ends of multiple bars 200, with high chamfering efficiency, low labor cost and time cost, and being safe and reliable.
