DETAILED DESCRIPTION

[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The following describes a metal part rounding device according to an embodiment of the present application with reference to the accompanying drawings.

[0029] like Figure 1-Figure 8 As shown, the metal part rounding device of the embodiment of the present application may include: a stand 1, two sets of clamping mechanisms 2, a rounding mechanism 3 and an auxiliary mechanism 4.

[0030] Among them, a plurality of rollers 11 are rotatably connected to the stand 1, and the plurality of rollers 11 are used to assist the movement of the metal parts to be processed.

[0031] It should be noted that the multiple rollers 11 described in this embodiment are rotatably connected to the stand 1 , and the multiple rollers 11 are arranged in equal numbers on both sides of the auxiliary mechanism 4 .

[0032] The two clamping mechanisms 2 are symmetrically arranged on the platform 1 , and the clamping mechanisms 2 include a first driving component 21 and two fixing components 22 .

[0033] Among them, the first driving component 21 is connected to the stand 1, and the first driving component 21 is used to apply force to the metal part on its upper side and can drive the metal part to move. The two fixing components 22 are symmetrically arranged on the inner side of the first driving component 21, and the two groups of fixing components 22 are used to apply force to the metal part on both sides.

[0034] The corner-rounding grinding mechanism 3 is disposed between the two clamping mechanisms 2 , and the corner-rounding grinding mechanism 3 comprises two connecting plates 31 , a rotation driving assembly 32 , a revolution driving assembly 33 and a grinding roller assembly 34 .

[0035] Among them, the two ends of the two connecting plates 31 are respectively connected to the two groups of clamping mechanisms 2, the rotation drive assembly 32 and the revolution drive assembly 33 are respectively connected to the two connecting plates 31, the rotation drive assembly 32 and the revolution drive assembly 33 are respectively connected to the grinding roller assembly 34, the rotation drive assembly 32 is used to drive the grinding roller assembly 34 to rotate quickly to grind the metal parts, and the revolution drive assembly 33 is used to drive the grinding roller assembly 34 to rotate to change the grinding position of the metal parts.

[0036] The self-rotation drive assembly 32 includes an inner cover 322, which is connected to the connecting plate 31. Two grooves 35 are symmetrically provided on the inner cover 322. The grooves 35 are arranged in a spiral structure, and the two ends of the two grooves 35 are connected to each other. One end of the grinding roller assembly 34 passes through the grooves 35 and extends to the interior of the inner cover 322. The grooves 35 are used to limit one end of the grinding roller assembly 34.

[0037] The auxiliary mechanism 4 is located below the corner-rounding grinding mechanism 3 . The auxiliary mechanism 4 is connected to the stand 1 . The auxiliary mechanism 4 is used to collect and process the coolant.

[0038] In an embodiment of the present application, a controller (not shown in the figure) is installed on a stand 1, and a clamping mechanism 2, a corner grinding mechanism 3 and an auxiliary mechanism 4 are respectively connected to the controller. Relevant technicians can input the operating data of the equipment (for example, the rotation speed of the grinding roller assembly 34, the moving speed of the metal parts, etc.) into the controller to ensure the normal operation of the equipment.

[0039] Specifically, relevant technicians (for example, workers) use this equipment to perform rounding processing on metal parts (metal grooves) used in a batch of suspension rods, with the purpose of rounding the tip of the metal groove to avoid danger in subsequent production and use.

[0040] First, an operation signal is sent to the clamping mechanism 2 through the controller, and the first drive component 21 in the clamping mechanism 2 starts to run. The worker selects one end of the metal part to be rounded and places the metal part between the clamping mechanism 2 and multiple rollers 11. Under the action of the first drive component 21, the metal part moves at a uniform speed.

[0041] When the metal part moves to the first preset position (this working condition can be obtained through the position sensor), the first drive component 21 stops running, the two fixing components 22 fix the two sides of the metal part, the controller sends an operation signal to the corner grinding mechanism 3, the rotation drive component 32 starts to run, the grinding roller component 34 rotates rapidly, the rotation drive component 32 drives the revolution drive component 33 to run, the grinding roller component 34 rotates, and the grinding roller component 34 performs corner grinding on the tip of the metal part.

[0042] While the revolution drive assembly 33 drives the grinding roller assembly 34 to rotate, the grinding roller assembly 34 is restricted by the groove body 35 to reciprocate up and down, thereby changing the contact position between the grinding roller assembly 34 and the metal part, so that the grinding roller assembly 34 is fully utilized, thereby reducing the replacement frequency of the grinding roller assembly 34.

[0043] After one end of the metal piece is processed, the two fixing components 22 release the fixation of the two sides of the metal piece, the first driving component 21 continues to operate, and the metal piece moves toward the other assembly clamping mechanism 2.

[0044] When the metal piece moves to the second preset position (this working condition can be obtained by the position sensor), the first driving component 21 in the other assembly clamping mechanism 2 stops running, and the two fixing components 22 fix the two sides of the metal piece.

[0045] The grinding roller assembly 34 gradually approaches the other end of the metal part, and the grinding roller assembly 34 continues to rotate, thereby rounding the other end of the metal part, thereby eliminating the need for relevant technicians to replace the processed end of the metal part, simplifying the operating steps and improving the processing efficiency of the metal part. After the processing is completed, the first drive assembly 21 is operated, and the two fixing assemblies 22 release the fixation on both sides of the metal part, and unloading can be completed at the other end of the equipment.

[0046] As a possible situation, according to the technical requirements, if the diameter of the fillet required for the metal part is large, the equipment cannot meet the required technical requirements in one processing. During the processing, the two sets of clamping mechanisms 2 can reciprocate and drive the metal part, thereby performing multiple grinding processes on the metal part so that the fillet grinding of the metal part meets the technical requirements.

[0047] As another possible situation, if only one side of the sharp corner of the metal part needs to be rounded during the rounding process, the above steps can be followed. When the grinding roller assembly 34 is grinding the rounded corner, the first drive assembly 21 can push the metal part backward, thereby preventing the grinding roller assembly 34 from contacting the other side of the sharp corner of the metal part, thereby achieving the purpose of grinding only one side of the sharp corner.

[0048] In one embodiment of the present application, Figure 2 and Figure 3As shown, the self-rotation driving assembly 32 also includes a driving motor 321 , a connecting shaft 323 , a driving herringbone gear 324 and a driven herringbone gear 325 .

[0050] It can be understood that, through the meshing connection between the driven herringbone gear 325 and the driving herringbone gear 324 , the driven herringbone gear 325 and the driving herringbone gear 324 can support each other.

[0051] In one embodiment of the present application, Figure 2-Figure 4 As shown, the revolution driving assembly 33 includes a driving gear 331 , a reduction gear 332 , a ring gear 333 and an outer cover 334 .

[0053] It should be noted that the gear ring 333 and the outer cover 334 described in this embodiment are rotatably connected via a slewing bearing.

[0054] It should be noted that the diameter of the driving gear 331 is smaller than the diameter of the reduction gear 332 , and the diameter of the reduction gear 332 is smaller than the diameter of the ring gear 333 , thereby achieving a deceleration effect, making the turnover speed of the grinding roller assembly 34 slower.

[0055] In one embodiment of the present application, Figure 2-Figure 6 As shown, the grinding roller assembly 34 includes a first grinding roller 341 , a rod body 342 and a limiting member 343 .

[0056] Among them, the first grinding roller 341 is connected to one end of the rod body 342, the other end of the rod body 342 passes through the driven herringbone gear 325 and the ring gear 333 in sequence, the rod body 342 is slidingly connected with the driven herringbone gear 325 and the ring gear 333, the other end of the rod body 342 extends between the inner cover 322 and the outer cover 334, and the limit piece 343 is rotatably connected to the other end of the rod body 342.

[0057] It should be noted that, refer to Figure 6 The rod body 342 described in this embodiment is slidably connected with the driven herringbone gear 325. A sliding groove is provided on the rod body 342, and the driven herringbone gear 325 is engaged with the sliding groove on the rod body 342, so that the driven herringbone gear 325 can both drive the rod body 342 to rotate and the rod body 342 can slide with the driven herringbone gear 325.

[0058] Specifically, during the operation of the corner rounding mechanism 3, first, the driving motor 321 drives the active herringbone gear 324 to rotate, the active herringbone gear 324 is meshed and connected with the driven herringbone gear 325, the driven herringbone gear 325 drives the rod body 342 and the first grinding roller 341 to rotate rapidly, the first grinding roller 341 contacts the sharp corner of the metal part, thereby performing corner rounding processing on the metal part.

[0059] At the same time, the driving motor 321 also drives the active gear 331 to rotate, the active gear 331 is meshed with the reduction gear 332, the reduction gear 332 is meshed with the ring gear 333, the ring gear 333 rotates, and the ring gear 333 drives the rod body 342 and the first grinding roller 341 to rotate, so as to round the corners of the other end of the metal part, thereby simplifying the operation steps and eliminating the need for workers to assist in adjusting the processing position of the metal part.

[0060] When the ring gear 333 drives the rod body 342 and the first grinding roller 341 to rotate, the limit member 343 moves along the track of the groove body 35, and the rod body 342 and the first grinding roller 341 reciprocate up and down, thereby changing the contact position between the first grinding roller 341 and the tip of the metal part, so that the first grinding roller 341 is fully utilized, thereby reducing the replacement frequency of the first grinding roller 341.

[0061] In one embodiment of the present application, Figure 5 As shown, the limiting member 343 includes a first connecting rod 3431 , a second connecting rod 3432 , a mounting seat 3433 and a roller 3434 .

[0063] Specifically, when the rod body 342 drives the limit piece 343 to move along the groove body 35, one end of the first connecting rod 3431 is rotationally connected to the rod body 342, the second connecting rod 3432 is inserted into the groove body 35, and the roller 3434 rolls on the inner wall of the inner cover 322, so as to reduce the friction between the limit piece 343 and the inner cover 322.

[0064] In one embodiment of the present application, Figure 1 and Figure 7 As shown, the first driving assembly 21 includes a bracket 211 , a connecting frame 212 , a hand-screw rod 213 , a mounting frame 214 , a driving component 216 and two pressure rollers 215 .

[0069] The worker places the metal piece to be rounded between the pressure roller 215 and the roller shaft 11, and the driving component 216 starts to operate, driving the metal piece to move.

[0070] When the metal piece moves to the preset position, the controller sends an operation signal to the fixing component 22, and the hydraulic telescopic rod 221 starts to operate.
