Description

Technical Field

[0001] The invention relates to the technical field of pin processing, in particular to a connecting rod pin processing device. Background Art

[0002] In a connecting rod mechanism, the pin is usually used as a fulcrum for connecting rods. The pin of the connecting rod is an important component used to connect two connecting rod parts and allow them to rotate relative to each other. During the processing of the connecting rod pin, the pin is usually cut to a corresponding length. In this way, in the subsequent processing, it is sometimes necessary to grind the end of the pin to remove burrs and grind the end. In order to improve the smoothness of the pin surface, the pin surface is usually polished. During use, in order to prevent the pin from moving during the processing, the pin is usually clamped and fixed. In this way, in the continuous processing process, it is necessary to wait for each pin to be clamped and released in turn, which is cumbersome and not conducive to the rapid processing of the connecting rod pin.

DETAILED DESCRIPTION

[0067] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] See also Figure 1-10 In an embodiment of the present invention, a connecting rod pin processing device includes:

[0069] The conveying module 100 is used to convey the pin shaft. The conveying module 100 includes two bottom plates 110 and two conveying mechanisms 120. The two conveying mechanisms 120 are both located on the top of the two bottom plates 110. A plurality of placement mechanisms 130 are arranged between the two conveying mechanisms 120. The placement mechanism 130 includes two support rods 131. A positioning plate 132 is arranged between the two support rods 131. The inner side of the positioning plate 132 is fixedly connected to a rectangular rod 133 that is slidably connected to the inner side surfaces of the two support rods 131.

[0070] A grinding module 200 is arranged inside the conveying module 100, and is used for grinding the end of the pin shaft; a limiting module 300 is arranged on the top of the conveying module 100, and is used for limiting the pin shaft; a polishing module 400 is arranged on the top of the conveying module 100, and is used for polishing the pin shaft; two lifting modules 500 are respectively arranged on the top of the limiting module 300 and the polishing module 400, and the lifting module 500 is used to adjust the height of the limiting module 300 and the polishing module 400.

[0072] Specifically, the pin shaft can be placed between the support rods 131 on the same side of two adjacent placement mechanisms 130, and the large end of the pin shaft can be clamped between the support rod 131 and the clamping plate 132. Two rows of pin shafts can be placed on the placement mechanism 130, so that the conveying mechanism 120 can convey the pin shaft through the placement mechanism 130. At the same time, a transmission roller can be driven to rotate by the conveying motor 330, and the transmission roller can drive the conveyor belt 320 to move. The conveyor belt 320 can drive the fixed seat 340 thereon to move, so that the abutment rod 341 moves, and the abutment rod 341 can be moved to the top of the corresponding pin shaft, so that the pin shaft can be pressed against the rubber ring of the support rod 131 through the abutment rod 341, thereby limiting the position of the pin shaft. When the pin shaft moves to the position of the grinding module 200, the end of the pin shaft can be grinded by the grinding module 200 to remove the burrs on the small end of the pin shaft and grind the small end of the pin shaft. It is relatively simple to fix and release the pin shaft. In the process of conveying the pin shaft, the pin shaft can be continuously fixed and released. At the same time, it can adapt to the fixing of pin shafts of different sizes, which is beneficial to improve the processing speed of the pin shaft.

[0077] During specific implementation, the support frame 122 can support the side frame 121, the positioning plate 128 can fix the limiting plate 123 on the side frame 121, the limiting plate 123 can support the rotating ring 135, so as to support the placement mechanism 130, the positioning plate 132 can move along the center plate 150, the center plate 150 can position the positioning plate 132, limit the position of the positioning plate 132, and can drive the adjacent transmission rod 124 to rotate through the power motor 160, the transmission rod 124 can drive the transmission wheel 125 thereon to rotate, the transmission wheel 125 can drive the transmission belt 126 to rotate, and the transmission belt 126 can drive the connecting rod 134 to move, and the transmission rod 124 can drive the adjacent The linkage rod 151 rotates. Since the cross-section of the rectangular rod 152 is rectangular, the linkage rod 151 can drive the rectangular rod 152 to rotate, and the rectangular rod 152 can drive the adjacent transmission rod 124 to rotate, so that the transmission rods 124 of the two conveying mechanisms 120 rotate synchronously, and then the transmission belt 126 synchronously drives the connecting rod 134 to move, and the connecting rod 134 can drive the support rod 131 to move, so that the rotating ring 135 moves along the inner side surface of the side frame 121 and the side surface of the limit plate 123, so that the placement mechanism 130 moves in a circle along the edge of the limit plate 123, thereby driving the placement mechanism 130 to move through the conveying mechanism 120, and conveying the pin shaft through the placement mechanism 130.

[0080] Embodiment 2

[0081] Based on the first embodiment, Figure 7-9As shown, in this embodiment, the grinding module 200 includes: a fixed frame 210, which is arranged between the two base plates 110, and the inner side surface of the fixed frame 210 is rotatably connected to the two-way screw rod 211; two connecting frames 220, which are slidably connected inside the fixed frame 210, and the inner side surfaces of the bottoms of the two connecting frames 220 are both screwed and connected to the sides of the two-way screw rod 211, and the top of the inner side surface of the connecting frame 220 is rotatably connected to the driving shaft 1 222, and the tops of the two connecting frames 220 are fixedly connected to the driving motor 1 221, and the bottom of the inner side surface of the connecting frame 220 is rotatably connected to the driving shaft 223, and the side of the driving shaft 223 and the side of the driving shaft 1 222 are fixedly sleeved with pulleys 224, and the two pulleys 224 are connected through belt transmission; a driving motor 270 is fixedly connected to the bottom of the side of a connecting frame 220. , the output end of the driving motor 270 is drivingly connected to the end of the adjacent driving shaft 223; the two rotating disks 230 are respectively rotatably connected to the top of the opposite surfaces of the two connecting frames 220, and the side of the rotating disk 230 is fixedly connected to the end of the adjacent driving shaft 1 222, and a conical grinding block 231 is provided on one side of the opposite surfaces of the two rotating disks 230; the two sleeves 240 are respectively fixedly connected to the bottom of the opposite surfaces of the two connecting frames 220, and the inner side of one sleeve 240 is slidingly connected to the side of the other sleeve 240; the fixed shaft 250 is located inside one sleeve 240; the rectangular rod three 260 is located inside the other sleeve 240, the inner side of the fixed shaft 250 is slidingly connected to the side of the rectangular rod three 260, and the end of the fixed shaft 250 away from the rectangular rod three 260 is fixedly connected to the end of the adjacent driving shaft 223.

[0082] The inner side surface of the rotating disk 230 is rotatably connected to a connecting shaft 1 232 fixedly connected to the side surface of the conical grinding block 231, and the inner side surface of the rotating disk 230 is rotatably connected to a connecting shaft 233 rotatably connected to the inner side surface of the driving shaft 1 222. The output end of the driving motor 1 221 is transmission-connected to the end of the adjacent connecting shaft 233, and the side surfaces of the connecting shaft 233 and the connecting shaft 1 232 are both fixedly sleeved with a transmission gear 234, and the two transmission gears 234 are meshed for transmission.

[0083] In a specific implementation, the bidirectional screw rod 211 can limit the position of the connecting frame 220, and the bidirectional screw rod 211 can be rotated to make the two connecting frames 220 move toward or away from each other, so that the two sleeves 240 can be extended and retracted, and at the same time, the rectangular rod 3 260 can move inside the fixed shaft 250, and the connecting frame 220 can drive the rotating disk 230 to move. In this way, the spacing between the two conical grinding blocks 231 can be adjusted according to the length of the pin shaft, so that the conical grinding block 231 corresponds to the small end of the pin shaft, and the pin shaft is moved to the grinding module 200. When the positioning plate 132 is placed, the connecting teeth in the positioning plate 132 will mesh with a rack on the top of the center plate 150. At this time, the placement mechanism 130 stops moving, and when the pin shaft stays at the position of the conical grinding block 231, a rack can be used to prevent the connecting teeth from rotating, thereby preventing the positioning plate 132 from rotating. The positioning plate 132 can prevent the support rod 131 from rotating through the rectangular rod 133. Since the abutment rod 341 presses the pin shaft against the rubber ring of the support rod 131, the support rod 131 can limit the pin shaft through the rubber ring. Rotate, so that after the end of the pin shaft contacts the top of the side of the conical grinding block 231, the connecting shaft 233 can be driven to rotate by the driving motor 1 221, and the connecting shaft 233 can drive the connecting shaft 1 232 to rotate through the transmission gear 234, and the connecting shaft 1 232 can drive the conical grinding block 231 to rotate, and the conical grinding surface of the conical grinding block 231 can be used to grind the end of the pin shaft. At the same time, the driving motor 270 can be used to drive the driving shaft 223 to rotate.

In order to improve the smoothness of the pin shaft surface, when the placement mechanism 130 moves, the other rack can rotate the positioning plate 132 through the connecting tooth, and the positioning plate 132 can drive the support rod 131 to rotate through the rectangular rod 133, and the support rod 131 can rotate the pin shaft through the rubber ring to make the pin shaft rotate, so that the side of the pin shaft can be fully polished, and a conveying roller 2 440 can be driven to rotate by the conveying motor 3 412, and the conveying roller 2 440 can drive the conveyor belt 3 450 to move, so that the conveyor belt 3 450 drives the connecting seat 460 and the round rod 461 to move, so that the round rod 461 moves with the placement mechanism 130, and when the placement mechanism 130 and the pin shaft pass the bottom of the conveyor belt 3 450, the round rod 461 always presses the pin shaft against the support rod 131, so that the pin shaft is polished by the conveyor belt 3 450.
