[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] This utility model provides a special deburring device for the mating surface of connecting rods. Multiple connecting rods 4 can be clamped at one time by tooling fixture 21, and the grinding components 35 in the multiple deburring devices 3 can grind multiple connecting rods 4 at the same time, avoiding idleness, with high working efficiency, and can meet the needs of mass production on the production line.

[0047] Please refer to this as well. Figures 1 to 8 The special deburring equipment for connecting rod mating surfaces provided by this utility model includes:

[0048] Base plate 1;

[0049] A rotary worktable 2 is provided on the base plate 1. Multiple sets of tooling fixtures 21 are provided on the rotary worktable 2 along the circumferential direction. The tooling fixtures 21 are used to clamp multiple connecting rods 4 at the same time.

[0050] Multiple deburring devices 3 are installed on the base plate 1 and distributed around the rotary worktable 2. Each deburring device 3 includes a slide table 32 slidably connected to the base plate 1, a drive motor 34 installed on the slide table 32, and a grinding assembly 35 that is connected to the drive motor 34 in a transmission manner.

[0051] The tooling fixture 21 can clamp multiple connecting rods 4 at once. As the rotary table 2 rotates, the tooling fixture 21 moves to a designated position. At this position, the deburring device 3 works, causing the slide table 32 to slide on the base plate 1, bringing the grinding assembly 35 close to and in contact with the connecting rod 4. The drive motor 34 drives the grinding assembly 35 to work, removing the burrs from the connecting rod 4. Then, the slide table 32 moves, causing the grinding assembly 35 to retract. As the rotary table 2 rotates, the connecting rod 4 is transferred to the deburring device 3 at the next position. Through the coordinated operation of multiple sets of deburring devices 3, the burrs on the mating surface of the connecting rod 4 and the end faces on both sides of the mating surface are removed.

[0052] With this setup, the tooling fixture 21 can clamp multiple connecting rods 4 at once, and the grinding component 35 of the deburring device 3 can grind multiple connecting rods 4 simultaneously. Through the coordinated operation of multiple sets of deburring devices 3, the burrs on the mating surfaces of the connecting rods 4 and the end faces on both sides of the mating surfaces are removed, resulting in high working efficiency and meeting the needs of mass production on the production line.

[0053] In some embodiments, please refer to the following: Figures 1 to 2 The number of tooling fixtures 21 is four sets, and the four sets of tooling fixtures 21 are evenly distributed. The number of deburring devices 3 is three sets, and the three sets of deburring devices 3 are distributed in a triangular shape.

[0054] For ease of description, let's use Figure 1 Taking the up, down, left, and right directions as an example, the three deburring devices 3 are located on the left, top, and right sides of the rotary table 2, respectively. The lower side of the rotary table 2 without the deburring devices 3 is the loading and unloading station of the rotary table 2. During operation, multiple connecting rods 4 are first clamped by the tooling fixture 21 at the loading and unloading station. Then, the rotary table 2 rotates 90°, causing the tooling fixture 21 to move to the deburring device 3 on the left side of the rotary table 2. When the deburring device 3 at this location is working, multiple connecting rods 4 are clamped again by the tooling fixture 21 at the loading and unloading station of the rotary table 2. After the deburring device 3 on the left side of the rotary table 2 completes the deburring operation, the rotary table 2 rotates 90° again. At this time, the deburring devices 3 on the left and top sides of the rotary table 2 are working, and the loading and unloading of the rotary table 2 is also in operation. Multiple connecting rods 4 are clamped at the workstation by the tooling fixture 21. After the deburring devices 3 on the left and upper sides of the rotary worktable 2 complete their work, the worktable rotates 90°. The deburring devices 3 on the left, upper and right sides of the rotary worktable 2 work simultaneously. At the same time, multiple connecting rods 4 are clamped at the loading and unloading station of the rotary worktable 2 by the tooling fixture 21. After the deburring devices 3 on the left, upper and right sides of the rotary worktable 2 complete their deburring work, the worktable rotates 90°. The first batch of connecting rods 4 that have completed three deburring operations are moved to the loading and unloading station for unloading. After unloading, they can be reloaded.

[0055] This setup allows multiple deburring devices 3 to operate simultaneously, avoiding idle periods and effectively improving the utilization efficiency of the deburring devices 3, thereby increasing production efficiency.

[0056] In some embodiments, please refer to the following: Figures 1 to 2 Two sets of adjacent deburring devices 3 are used to remove burrs from the mating surface of the connecting rod body 4, and another set of deburring devices 3 is used to remove burrs from the end faces of both sides of the mating surface of the connecting rod body 4.

[0057] Specifically, in this embodiment, two sets of deburring devices 3 located on the left and upper sides of the rotary table 2 remove burrs from the mating surface of the connecting rod body 4, and a deburring device 3 located on the right side of the rotary table 2 removes burrs from the end faces of both sides of the mating surface of the connecting rod body 4. Through the combined action of multiple sets of deburring devices 3, burrs on the connecting rod body 4 are completely removed.

[0058] In some embodiments, please refer to the following: Figures 1 to 3 The drive motor 34 is fixedly mounted on the mounting plate 33, and the mounting plate 33 is mounted on the top of the slide table 32 via the swing assembly 36.

[0059] By setting the oscillating component 36, the up-and-down oscillation during manual sanding can be simulated, thus improving the burr removal effect.

[0060] In some embodiments, please refer to the following: Figures 1 to 4 The swing assembly 36 includes:

[0061] The geared motor 361 is fixedly mounted on one side of the top of the slide table 32, and the output shaft of the geared motor 361 is fixedly connected to the connecting plate 362.

[0062] The hinge rod 363 has one end hinged to the connecting plate 362 and the other end hinged to the mounting plate 33;

[0063] Hinge 364 is located between slide 32 and mounting plate 33, and slide 32 and mounting plate 33 are hinged together by hinge 364.

[0064] When the drive motor 34 drives the grinding assembly 35 to remove burrs, the reduction motor 361 is started. The reduction motor 361 outputs rotational motion to drive the connecting plate 362 to rotate. As the connecting plate 362 rotates, the hinge rod 363 causes the mounting plate 33 to swing up and down, thereby enabling the drive motor 34 and the grinding assembly 35 mounted on the mounting plate 33 to swing up and down. The up and down swing of the grinding assembly 35 simulates the up and down swing of a human hand during grinding, thus improving the grinding effect.

[0065] In some embodiments, please refer to the following: Figures 5 to 6 The polishing component 35 includes:

[0066] Two fixed bearing housings 351;

[0067] A connecting shaft 352 is rotatably connected between two bearing seats 351, and a synchronous pulley 353 is fixedly provided at one end of the connecting shaft 352;

[0068] Multiple brushes 355 are fitted and fixed to the connecting shaft 352;

[0069] The output shaft of the drive motor 34 is fixedly equipped with a transmission wheel, which is connected to the synchronous pulley 353 via a synchronous belt 354.

[0070] The connecting shaft 352 is horizontally rotatably connected between two spaced bearing seats 351. When removing burrs, the drive motor 34 outputs rotational motion, which drives the connecting shaft 352 to rotate through the transmission of the synchronous belt 354. Multiple brushes 355 on the connecting shaft 352 rotate synchronously, and the connecting rod 4 is polished through the contact between the multiple brushes 355 and the connecting rod 4.

[0071] In practical use, by making the brush 355 contact different positions of the connecting rod body 4, the burrs on the mating surface of the connecting rod body 4 and the burrs on both sides of the mating surface of the connecting rod body 4 can be removed.

[0072] In addition, two nuts 356 are threaded onto the connecting shaft 352. Multiple brushes 355 are fitted onto the connecting shaft 352, with the two nuts 356 located on both sides of the brushes 355 and pressing against the sides of the brushes 355 for fixation. Multiple brushes 355 are assembled into a large brush 355, making it convenient to replace damaged parts individually instead of replacing all of them. The brushes 355 can be made of silicon carbide.

[0073] In some embodiments, the connecting shafts 352 in the two sets of deburring devices 3 used to remove burrs from the mating surfaces of the connecting rod body 4 rotate in opposite directions.

[0074] This configuration ensures that the brushes 355 in the two sets of deburring devices 3 rotate in opposite directions, so that when removing burrs, the brushes 355 in the two sets of deburring devices 3 can contact the connecting rod body 4 from two directions, thus avoiding the situation where burrs are not completely removed.

[0075] In some embodiments, please refer to the following: Figures 1 to 2 , Figures 7 to 8 The tooling fixture 21 includes:

[0076] Positioning plate 211 is fixedly mounted on rotary table 2, and positioning plate 211 is provided with positioning groove for placing connecting rod body 4;

[0077] Multiple corner cylinders 212 are installed on the positioning plate 211, and the extension and retraction ends of the corner cylinders 212 are fixedly provided with pressure plates 213.

[0078] Among them, the corner cylinder 212 is located between two adjacent positioning slots, and the corner cylinder 212 simultaneously presses the two connecting rod bodies 4 through the pressure plate 213.

[0079] When using the tooling fixture 21, firstly, multiple connecting rods 4 are placed in the corresponding positioning slots of the positioning plate 211. Then, multiple corner cylinders 212 operate, their telescopic ends rotating and moving downwards, causing the pressure plate 213 to press the connecting rods 4 together. Specifically, the telescopic ends of the corner cylinders 212 are hinged to the middle of the pressure plate 213, so that both sides of the pressure plate 213 can simultaneously press and fix the connecting rods 4 on both sides.

[0080] After grinding, when unloading through the loading and unloading station, the corner cylinder 212 drives the pressure plate 213 to move and loosen the connecting rod 4. During other operations, the corner cylinder 212 always presses the connecting rod 4 through the pressure plate 213 to ensure that the connecting rod 4 is reliably fixed when grinding and rotating the rotary table 2, thus improving the stability of use.

[0081] In some embodiments, please refer to the following: Figures 7 to 8 The number of positioning slots on the positioning plate 211 is six, and the number of corner cylinders 212 is three.

[0082] Six connecting rods 4 can be placed in the six positioning slots. The grinding component 35 of the deburring device 3 can grind multiple connecting rods 4 at the same time, which is highly efficient and can meet the needs of mass production on the production line.

[0083] In some embodiments, please refer to the following: Figures 2 to 3 The deburring device 3 also includes a slide motor 31, the output end of which is connected to the slide 32 via a coupling and a lead screw and nut mechanism.

[0084] The slide table motor 31 outputs rotational motion. The output end of the slide table motor 31 is connected to the lead screw in the lead screw and nut mechanism through a coupling. The lead screw and nut mechanism converts the rotational motion output by the slide table motor 31 into linear motion, thereby driving the slide table 32 to move on the base plate 1. As the slide table 32 moves, the brush 355 approaches and contacts the connecting rod body 4 held by the tooling fixture 21 on the rotary worktable 2 for grinding.

[0085] In addition, to achieve clean production, the deburring equipment for the connecting rod body mating surface is also equipped with a protective cover. The protective cover encloses the rotary worktable 2 and multiple sets of deburring devices 3. The protective cover has an opening near the loading and unloading station of the rotary worktable 2 for easy loading and unloading. An air outlet can be installed on the top of the protective cover, which is connected to the air inlet of a dust collection device to remove dust and other particles generated during the grinding process.

[0086] The deburring equipment for connecting rod mating surfaces provided by this utility model uses a tooling fixture 21 to clamp multiple connecting rods 4 at once. The grinding component 35 of the deburring device 3 can simultaneously grind multiple connecting rods 4. Through the coordinated operation of multiple sets of deburring devices 3, burrs on the mating surfaces and the end faces on both sides of the mating surfaces of the connecting rods 4 are removed, resulting in high working efficiency and meeting the needs of mass production lines. A swing component 36 is provided between the slide table 32 and the mounting plate 33. The up-and-down swing of the grinding component 35 simulates the up-and-down swing of manual grinding, improving the burr removal effect.

[0087] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0088] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
