Rolling treatment apparatus for diesel engine connecting rod machining

Abstract

This utility model relates to the field of rolling processing technology, and more particularly to rolling processing equipment for diesel engine connecting rods. It mainly addresses the problem that the surface of the diesel connecting rod needs to be ground before rolling deformation, which affects rolling efficiency. The proposed technical solution includes a control pipe, one end of which is fixedly connected to a slide rail. Multiple sets of slide rails are arranged in a circumferential array, and sliders are slidably connected to the outside of the slide rails. This utility model uses polishing paper to polish the areas of the diesel connecting rod that need to be rolled, thereby removing rust and impurities. When the slide rail is pressed down, it drives a positioning rod to press against a rotating rod, causing the rotating rod to move the connecting rod and positioning plate into the control pipe. This allows the positioning plate to automatically retract the polishing paper into the control pipe, improving the rolling efficiency of the diesel connecting rod.

Description

Technical Field

[0001] This utility model relates to the field of rolling processing technology, and in particular to rolling processing equipment for diesel engine connecting rod processing. Background Technology

[0002] Roller burnishing is a chipless machining process that utilizes the plastic deformation properties of metals at room temperature to apply pressure to the surface of a workpiece using a roller burnishing tool to improve its performance. When used in diesel connecting rods, roller burnishing is required on the ends.

[0003] The existing method involves clamping and rotating the diesel connecting rod. As the connecting rod rotates, the rolling roller retracts, pressing against the surface of the diesel connecting rod to deform it.

[0004] However, the surface of the diesel engine connecting rod needs to be ground before rolling deformation, which affects the rolling efficiency. Therefore, this invention proposes a rolling processing device for diesel engine connecting rod machining. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that when performing rolling deformation, the surface of the diesel connecting rod needs to be ground before rolling deformation, which affects the rolling efficiency. Therefore, this invention proposes a rolling processing device for diesel engine connecting rod processing.

[0006] The technical solution of this utility model: a rolling processing equipment for diesel engine connecting rod processing, including a control pipe, one end of which is fixedly connected to a slide rail, the slide rail having multiple sets arranged in a circumferential array, a slider slidably connected to the outside of the slide rail, a rolling wheel fixedly connected to one side of the slider, the slide rail being arranged in an "I" shape, and the slider being arranged in a "C" shape.

[0007] A positioning plate is provided below the slide rail, and a connecting rubber pad is fixedly connected to the bottom of the positioning plate. A sanding paper is glued to the bottom of the connecting rubber pad.

[0008] A positioning rod is fixedly connected to the side of the slide rail near the positioning plate, and a connecting component is provided on the outside of the positioning rod.

[0009] Optionally, the connecting assembly includes a rotating rod that is inclined toward the control pipe position. The rotating rod abuts against the positioning rod on the opposite side away from it. A connecting rod is rotatably connected to the outside of the rotating rod away from the positioning rod, and the connecting rod is fixedly connected to the positioning plate on the side away from the connecting pad.

[0010] Optionally, the connecting rods are arranged in multiple sets symmetrically, with the symmetrical connecting rods divided into two sets located on both sides of the rotating rod.

[0011] Optionally, the positioning rod has a rotating groove near the rotating rod, and a connecting component is provided inside the rotating groove.

[0012] Optionally, the connecting assembly includes a rotating shaft, which is rotatably connected inside a rotating groove, and the end of the rotating shaft away from the rotating groove is fixedly connected to one side of a rotating rod.

[0013] Optionally, a worm spring is fixedly connected to the outside of the rotating shaft, and the worm spring is arranged in a worm shape inside the rotating groove.

[0014] Optionally, a positioning block is fixedly connected to the end of the worm spring away from the rotating shaft, and the positioning block is fixedly connected inside the rotating groove.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] This invention uses polishing paper to polish the areas of the diesel connecting rod that need to be rolled, thereby removing rust and impurities from the areas to be rolled.

[0031] Example

[0032] like Figures 1 to 3As shown, the rolling processing equipment for diesel engine connecting rods proposed in this utility model includes a control pipe 1. One end of the control pipe 1 is fixedly connected to a slide rail 2. The slide rail 2 has multiple sets arranged in a circumferential array. A slider 3 is slidably connected to the outside of the slide rail 2. The slider 3 can slide outside the slide rail 2. A rolling roller 4 is fixedly connected to one side of the slider 3. The slide rail 2 is arranged in an "I" shape, and the slider 3 is arranged in a "C" shape. The "I" shape of the slide rail 2 and the "C" shape of the slider 3 can fit perfectly, allowing the slider 3 to slide along the inside of the slide rail 2. A positioning plate 5 is provided below the slide rail 2. A connecting rubber pad 6 is fixedly connected to the bottom of the positioning plate 5. The connecting rubber pad 6 can be repeatedly attached. A polishing paper 7 is glued to the bottom of the connecting rubber pad 6. The positioning plate 5 can drive the polishing paper 7 to polish the surface of the diesel connecting rod. A positioning rod 10 is fixedly connected to the side of the slide rail 2 near the positioning plate 5. The positioning rod 10 can be positioned. A connecting component is provided on the outside of the positioning rod 10.

[0033] For further details, please refer to Figure 4 and Figure 6 The connecting assembly includes a rotating rod 9, which is inclined toward the control pipe 1. The rotating rod 9 can retract along the positioning rod 10 into the control pipe 1. The rotating rod 9 abuts against the positioning rod 10 on the opposite side away from it. The rotating rod 9 can rotate on one side of the positioning rod 10. A connecting rod 8 is rotatably connected to the outside of the rotating rod 9 away from the positioning rod 10. The connecting rod 8 can rotate at one end of the rotating rod 9. The connecting rod 8 is fixedly connected to the positioning plate 5 on the side away from the connecting pad 6. The connecting rod 8, the rotating rod 9, and the positioning rod 10 can connect the slider 3 to the positioning plate 5. There are multiple sets of connecting rods 8 arranged symmetrically. The symmetrical connecting rods 8 are divided into two sets on both sides of the rotating rod 9. The two symmetrical arrangements of the connecting rods 8 can make the rotation of the rotating rod 9 more stable. The center position of the rolling roller 4 is set on one side of the slider 3 near the inside of the control pipe 1. The rolling roller 4 can more easily contact the surface of the diesel connecting rod.

[0034] For further details, please refer to Figure 4 and Figure 5The positioning rod 10 has a rotating groove 11 near the rotating rod 9. The rotating groove 11 facilitates the rotation of the rotating rod 9 on one side of the positioning rod 10. A connecting component is provided inside the rotating groove 11. The connecting component includes a rotating shaft 14, which is rotatably connected inside the rotating groove 11. The rotating shaft 14 has better protection and stability when rotating inside the rotating groove 11. The end of the rotating shaft 14 away from the rotating groove 11 is fixedly connected to one side of the rotating rod 9. A worm spring 12 is fixedly connected to the outside of the rotating shaft 14. The worm spring 12 can be wound and released inside the rotating shaft 14. The worm spring 12 is worm-shaped and is set inside the rotating groove 11. The worm-shaped structure of the worm spring 12 facilitates winding and releasing. A positioning block 13 is fixedly connected to the end of the worm spring 12 away from the rotating shaft 14. The positioning block 13 facilitates the positioning of the worm spring 12. The positioning block 13 is fixedly connected inside the rotating groove 11. The positioning block 13, together with the rotating shaft 14, can position the worm spring 12.

[0035] In this embodiment, during use, the diesel connecting rod rotates and inserts into the control pipe 1. At this time, the slider 3 will move along the outside of the slide rail 2. The positioning plate 5 will drive the polishing paper 7 fixed by the connecting rubber pad 6 to move closer to the position of the diesel connecting rod that needs to be rolled. In this way, the polishing paper 7 polishes away the impurities on the surface of the diesel connecting rod. When the slider 3 continues to move closer to the diesel connecting rod, the connecting rubber pad 6 will gradually retract into the control pipe 1. In this way, the rolling roller 4 can perform rolling treatment on the required position of the diesel connecting rod surface.

[0036] When the sanding paper 7 is sanding, the slide rail 2 continues to press down, which will drive the rotating rod 9 to rotate along one side of the positioning rod 10. This allows the rotating rod 9 to drive the connecting rod 8 and the positioning plate 5 to retract into the slide rail 2. The rotating rod 9 can better retract into the control pipe 1 by moving closer to the inside of the control pipe 1. The movement of the rotating rod 9 is adjusted by the rotation of the connecting rod 8 and the positioning rod 10.

[0037] After the rolling is completed, the slider 3 returns to its original position along the outside of the slide rail 2. The worm spring 12 can then be released inside the rotating groove 11 by the positioning block 13. In this way, the worm spring 12 can push the rotating shaft 14, which in turn drives the rotating rod 9 to return to its original position. When the slider 3 is pressed down, the rotating rod 9 can drive the rotating shaft 14 to wind up the worm spring 12, thereby ensuring that the spring force of the worm spring 12 is sufficient when the slider 3 returns to its original position.

[0038] It should be noted that this device uses polishing paper 7 to polish the areas of the diesel connecting rod that need to be rolled, thereby removing rust and impurities from the areas to be rolled. When the slide rail 2 is pressed down, the slide rail 2 will drive the positioning rod 10 to squeeze the rotating rod 9, thereby causing the rotating rod 9 to drive the connecting rod 8 and the positioning plate 5 to move into the control pipe 1. In this way, the positioning plate 5 can drive the polishing paper 7 to automatically retract into the control pipe 1, improving the rolling efficiency of the diesel connecting rod.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
