Description

Technical Field

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

[0002] The principle of cracking groove processing is to design and prefabricate a notch at the center of the big end hole of the connecting rod to form a stress concentration. Subsequently, a load perpendicular to the predetermined fracture surface is actively applied to induce cracking. With almost no deformation, the connecting rod is regularly fractured at the notch, thereby achieving chipless fracture separation of the connecting rod body and the connecting rod cover.

[0003] After searching, the Chinese patent with announcement number CN207267115U discloses a connecting rod cracking groove laser cutting system, which includes a laser fiber output component, a drive component, a connection component, a reflector component and a focusing cutting head that are assembled and installed in sequence; the reflector component includes a shell, and the side and bottom surfaces of the shell are respectively provided with a first through hole and a second through hole that are interconnected. A reflector is provided in the shell, and the first through hole and the second through hole are both opposite to the reflecting surface of the reflector. The connecting rod cracking groove laser cutting system provided by the above scheme avoids the high-frequency swing of the optical fiber with the focusing cutting head, greatly improving the reliability and service life of the connecting rod cracking groove laser cutting system; each component is detachable to facilitate system maintenance and debugging; and the stability and accuracy of the laser light path are ensured by the precise positioning and connection between the components, thereby improving the laser cutting accuracy of the connecting rod cracking groove. However, the above scheme still has the following shortcomings when used in practice:

[0004] When the connecting rod cracking groove processing device proposed in the above scheme is in use, the staff is required to manually place the crankshaft connecting rod into the positioning jig and manually remove it after the grooving is completed. This process produces significant problems. First, the shape of the positioning jig needs to be closely adapted to the shape of the crankshaft connecting rod to ensure the accuracy of the grooving. This tightly adapted design results in almost no gap between the positioning jig and the crankshaft connecting rod, which makes it difficult for the staff to quickly and smoothly remove the crankshaft connecting rod from the positioning jig after the grooving is completed. This operational inconvenience reduces production efficiency. Secondly, the entire removal process needs to be performed manually, which not only increases the labor intensity of the staff, but also easily leads to operational errors due to human factors. For example, the staff may apply uneven force when removing the crankshaft connecting rod, causing the crankshaft connecting rod to deform or damage; or the crankshaft connecting rod may not be removed in time due to fatigue, negligence, etc., affecting the subsequent production process.

[0005] Therefore, it is necessary to design a connecting rod laser grooving device to solve the above problems. Summary of the Invention

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Reference Figures 1-11A connecting rod laser grooving device includes a frame 101, a rotating table 102 is rotatably mounted on the frame 101, a servo motor 103 is mounted on the frame 101, the rotating table 102 is driven by the servo motor 103, a rotating rod 104 is fixed at the center position of the top surface of the rotating table 102, a rotating frame 105 is fixed at one end of the rotating rod 104 away from the rotating table 102, a fixed plate 3 is arranged above the frame 101, the fixed plate 3 is connected to the frame 101 through two vertical rods 2, an avoidance opening is opened at the center position of the fixed plate 3, the rotating rod 104 passes through the avoidance opening, and the rotating rod 104 and the avoidance opening do not contact each other, a laser grooving machine 4 is mounted on the fixed plate 3, and a blanking opening 301 is opened on the fixed plate 3.

[0041] Three positioning assemblies are arranged on the rotating frame 105, and the three positioning assemblies are distributed in a circumferential array around the rotating rod 104. The positioning assembly includes a positioning plate 51, a positioning groove 52 is opened on the top surface of the positioning plate 51, and a slot 53 is opened on the bottom surface of the positioning plate 51. The positioning groove 52 and the slot 53 are connected. Two movable sliding plates 54 are arranged on the positioning plate 51. The positioning assembly also includes four guide rods 55, four guide blocks 56, two through-holes 58 and two mounting plates 510. The four guide rods 55 are fixed on the groove wall of the slot 53, and the four guide blocks 56 are respectively fixed on the two sliding plates 54. At both ends, four guide blocks 56 are respectively slidably mounted on four guide rods 55. The four guide blocks 56 are connected to the groove wall of the slot 53 through connecting springs 57. Two through openings 58 are respectively opened on both sides of the positioning plate 51, and the two through openings 58 are connected to the slot 53. The two sliding plates 54 slide in the two through openings 58 respectively. The two sliding plates 54 are both fitted with the groove top position of the slot 53. The two mounting plates 510 are respectively arranged under the two sliding plates 54. The mounting plates 510 are connected to the corresponding sliding plates 54 through two connecting rods 59. Both mounting plates 510 are provided with inclined surfaces.

[0042] When the connecting rod laser grooving device proposed by the present invention is used, the staff starts the servo motor 103. When the servo motor 103 is running, it drives the rotating table 102 to rotate intermittently, and the angle of each rotation of the rotating table 102 is 120 degrees. When the rotating table 102 rotates, it can drive the rotating rod 104 to rotate, and the rotating frame 105 at the top of the rotating rod 104 also rotates accordingly. The rotating frame 105 can also drive the three positioning components to rotate, such as Figure 1 As shown, the three positioning components can all be moved to the bottom of the laser slotting machine 4 during the rotation process. It should be noted that the way in which the servo motor 103 drives the rotating table 102 to rotate is a prior art and will not be elaborated on here.

[0043] When grooving the crankshaft connecting rod, the staff first places the crankshaft in the positioning groove 52 on the positioning plate 51. The shape of the positioning groove 52 is the same as the shape of the crankshaft connecting rod. When the connecting rod is placed in the positioning groove 52, the outer surface of the connecting rod fits in with the groove wall of the positioning groove 52. At this time, the positioning groove 52 can provide positioning for the connecting rod, ensuring the grooving accuracy of the device for the connecting rod. For the two sliding plates 54, in the initial state, under the elastic force of the four connecting springs 57, the two sliding plates 54 are in contact with each other. At this time, the two sliding plates 54 jointly cover the positioning groove 52, working When the personnel puts the connecting rod into the positioning groove 52, the connecting rod will fall on the two sliding plates 54. Further, after the connecting rod is placed, the servo motor 103 runs and drives the rotating frame 105 to rotate 120°, so that the connecting rod rotates to the bottom of the laser grooving machine 4. At this time, the laser grooving machine 4 performs laser grooving on the connecting rod. The specific working principle of the laser grooving machine 4 is the existing technology and will not be elaborated on here. After the grooving is completed, the servo motor 103 continues to run and drives the rotating frame 105 to rotate 120° again, so that the positioning assembly carries the connecting rod to rotate to the top of the blanking port 301.

[0044] The frame 101 is provided with an automatic unloading assembly, which is arranged opposite to the unloading port 301. The automatic unloading assembly includes a mounting frame 61, a scissor-type lift 62, a lifting plate 63, a supporting plate 64 and a push rod 67. The mounting frame 61 is fixed on the frame 101, the scissor-type lift 62 is installed on the mounting frame 61, the lifting plate 63 is fixed on the lifting part of the scissor-type lift 62, the supporting plate 64 is arranged above the lifting plate 63, and the supporting plate 64 is arranged opposite to the unloading port 301. The blanking port 301 is set, and a soft pad is provided on the surface of the supporting plate 64. The supporting plate 64 and the lifting plate 63 are connected by two connecting parts 65. The top rod 67 is fixed to the lifting plate 63 through two brackets 66. The connecting part 65 includes an outer tube, an inner rod and a reset spring. The outer tube is fixed on the lifting plate 63, and the inner rod slides in the outer tube. The top end of the inner rod extends to the outside of the outer tube and is connected to the supporting plate 64. The two ends of the reset spring are respectively connected to the outer tube and the inner rod.

[0045] When the positioning assembly carries the connecting rod and rotates to the top of the blanking port 301, the automatic blanking assembly automatically blanks the connecting rod. Specifically, the scissor lift 62 operates to drive the lifting plate 63 to move upward. When the lifting plate 63 moves upward, it can drive the supporting plate 64 to move upward through the connecting piece 65. In this process, the supporting plate 64 will first contact the fixed plate 3 and face the blanking port 301. When the supporting plate 64 contacts the fixed plate 3, the top rod 67 has not yet contacted the two mounting plates 510. With the support of the scissor lift 62, the lifting plate 63 is automatically blanked. As the operation continues, the lifting plate 63 will continue to move upward. At this time, the supporting plate 64 is blocked by the fixed plate 3 and cannot move, which makes the lifting plate 63 and the supporting plate 64 approach each other. At this time, the outer cylinder connected to the lifting plate 63 will move and be sleeved on the inner rod. The design of the outer cylinder and the inner rod allows the lifting plate 63 and the supporting plate 64 to move relative to each other. During the relative movement of the two, the lifting plate 63 can drive the ejector rod 67 to move, so that the two ends of the ejector rod 67 respectively squeeze the inclined surfaces of the two mounting plates 510. When the two mounting plates 510 are pressed together, the lifting plate 63 and the supporting plate 64 are pressed together. When 510 is squeezed by the push rod 67, the two mounting plates 510 can move away from each other under the action of its inclined surface, and drive the two sliding plates 54 to move away from each other. When the two sliding plates 54 move away from each other, the two sliding plates 54 no longer block the positioning groove 52. Without the blocking of the two sliding plates 54, the connecting rod in the positioning groove 52 can fall on the supporting plate 64. Further, the scissor-type lift 62 drives the lifting plate 63 to move down and reset. In this process, the lifting plate 63 first moves away from the fixed plate 3, and the outer cylinder will also move down under the action of the reset spring. When the lifting plate 63 is lifted up, the lifting plate 63 is lifted up and the lifting plate 63 is lifted up. When the lifting plate 63 is lifted up, the lifting plate 63 is lifted up and the lifting plate 63 is lifted up. When the lifting plate 63 is lifted up, the lifting plate 63 is lifted up and the lifting plate 63 is lifted up, the lifting plate 63 is lifted up and the lifting plate 63 is lifted up. When the lifting plate 63 is lifted up, the lifting plate 63 is lifted up and the lifting plate 63 is lifted up, the lifting plate 63 is lifted up and the lifting plate 63 is lifted up.

[0046] A dust collection unit is arranged on the frame 101, and the dust collection unit includes a dust filtering component, a dust collection component and a lifting component.

[0047] The dust filter assembly includes a filter cartridge 71 and a filter element 73. The filter cartridge 71 is arranged on the frame 101. Several exhaust holes 72 are provided on the filter cartridge 71. The filter element 73 is arranged inside the filter cartridge 71. A through-hole is provided at the top of the filter element 73. A liftable exhaust head 81 is arranged inside the filter element 73. Several air outlets 82 are provided on the exhaust head 81. An air guide rod 83 is fixed on the exhaust head 81. The air guide rod 83 is hollow inside, and the interior of the air guide rod 83 is connected with the interior of the exhaust head 81. One end of the air guide rod 83 away from the exhaust head 81 passes through the through-hole and extends to the outside of the filter cartridge 71. The outer surface of the air guide rod 83 fits with the inner surface of the through-hole. The air guide rod 83 passes through the top of the filter cartridge 71 and is slidably connected to the filter cartridge 71.

[0048] The dust collection assembly includes a drive motor 74, an air suction cylinder 75, a first rotating shaft 76, an air suction fan 77 and an air suction pipe 78. The drive motor 74 is installed on the outer surface of the filter cylinder 71. The air suction cylinder 75 is fixed to the outer surface of the filter cylinder 71 through two rods. The first rotating shaft 76 passes through the air suction cylinder 75 and is rotatably connected to the air suction cylinder 75. One end of the first rotating shaft 76 is connected to the output shaft of the drive motor 74. The air suction fan 77 is fixedly mounted on the first rotating shaft 76, and the air suction fan 77 is arranged inside the air suction cylinder 75. The air suction pipe 78 is fixed on the laser cutting equipment. A number of air suction holes 79 are opened on the air suction pipe 78. The air suction end of the air suction cylinder 75 is connected to the air suction pipe 78 through a first hose, and the exhaust end of the air suction cylinder 75 is connected to the air guide rod 83 through a second hose.

[0049] The lifting assembly includes a cross bar 84, a second rotating shaft 85, an eccentric wheel 86, a first gear 87 and a second gear 88. The cross bar 84 is fixed to one end of the air guide rod 83 located outside the filter cylinder 71. The second rotating shaft 85 is rotatably installed on the outer surface of the filter cylinder 71. The eccentric wheel 86 is fixedly mounted on the second rotating shaft 85, and the eccentric wheel 86 is arranged opposite the cross bar 84. The first gear 87 is fixedly mounted on the second rotating shaft 85. The second gear 88 is fixedly mounted on the first rotating shaft 76. The first gear 87 and the second gear 88 are engaged with each other.

[0050] The connecting rod laser grooving device proposed in the present invention also has a smoke absorption function, which can prevent dust particles from entering the interior of the laser grooving machine 4. Dust particles may interfere with the transmission and focusing of the laser beam, affecting the accuracy and depth of the grooving. The smoke absorption function ensures the purity of the laser beam and improves the processing quality. Specifically, when performing laser grooving, the staff starts the drive motor 74. When the drive motor 74 is running, it drives the first rotating shaft 76 to rotate, and the suction fan 77 on the first rotating shaft 76 rotates accordingly. The suction fan 77 can extract air in the suction pipe 78 when it is running. , so that the several suction holes 79 on the suction pipe 78 can absorb the smoke and dust generated during the grooving process. Furthermore, the dust-laden airflow will be discharged into the interior of the air guide rod 83 under the guidance of the suction fan 77. The interior of the air guide rod 83 is connected with the interior of the exhaust head 81, so the dust-laden airflow will enter the interior of the exhaust head 81 and finally be ejected through the several air outlets 82. The exhaust head 81 is arranged inside the filter element 73. The filter element 73 can filter out the dust in the dust-laden airflow, and the clean air will pass through the filter element 73 and finally be discharged through the several exhaust holes 72, thereby realizing automatic filtration and collection of dust.

[0051] When the first rotating shaft 76 rotates, it can also drive the second rotating shaft 85 to rotate through the first gear 87 and the second gear 88 that are meshed with each other. When the second rotating shaft 85 rotates, it can drive the eccentric wheel 86 to rotate. When the eccentric wheel 86 rotates, it will periodically squeeze the cross bar 84. When the eccentric wheel 86 squeezes the cross bar 84, the cross bar 84 will move upward and drive the air guide rod 83 and the exhaust head 81 to move upward. When the eccentric wheel 86 separates from the cross bar 84, the air guide rod 83 and the exhaust head 81 will move downward under the action of gravity. Based on the above process, with the rotation of the eccentric wheel 86, The air guide rod 83 and the exhaust head 81 can move up and down inside the filter element 73. The up and down movement of the exhaust head 81 enables the dust-laden airflow to be evenly sprayed inside the filter element 73. The uniform distribution of dust helps the filter element 73 to capture dust particles more comprehensively, extend the service life of the filter element 73, reduce blockage and damage to the filter element 73 caused by local dust accumulation, maintain the air permeability of the filter element 73, ensure that the dust-laden airflow can smoothly pass through the filter element 73 for filtration, and improve the stability and reliability of the entire filtration system, and reduce the risk of system failure due to problems with the filter element 73.
