[0002] When casting the cylinder body through the mold, if the mold is not thoroughly cleaned after use, the residual impurities, sand particles, etc. will affect the next casting and cause burrs on the surface of the casting. In addition, burrs are also prone to form in the gap between the molds. The presence of burrs will reduce the surface quality of the cylinder body and affect the appearance.

[0003] The patent document with the authorization announcement number CN218776272U discloses a gasoline engine cylinder inner wall deburring device, which belongs to the technical field of deburring device.

[0029] like Figures 1 to 10 As shown, the deburring device for a casting cylinder body according to an embodiment of the present invention comprises a frame 1, a positioning member 2, a positioning shaft 3, a guide assembly, a grinding device, a driving assembly 1 and a driving member 4 81.

[0030] like Figure 2 and Figure 3As shown, the frame 1 is used to place the cylinder body 11 to be polished, the positioning member 2 is used to be connected to the robot arm, and the lifting and movement of the positioning member 2 can be controlled by the robot arm. The positioning shaft 3 is rotatably installed at the bottom of the positioning member 2, and the driving member 4 81 is fixedly installed on the positioning member 2. The driving member 4 81 can be a motor, and a gear 4 82 is fixedly installed on its output end. A gear 5 83 is fixedly installed on the positioning shaft 3, and the gear 5 83 is meshed with the gear 4 82, thereby controlling the operation of the driving member 4 81, and the positioning shaft 3 can be driven to rotate through the meshing transmission of the gear 4 82 and the gear 5 83.

[0031] like Figures 2 to 4 As shown, the guide assembly includes a mounting frame 41, a guide shaft 42 and an elastic telescopic rod 43. The mounting frame 41 is connected to the positioning shaft 3 through the elastic telescopic rod 43 so that the mounting frame 41 can approach or move away from the positioning shaft 3. Specifically, the elastic telescopic rod 43 includes a sleeve rod 431, a rod body 432 and an elastic member 433. The sleeve rod 431 is fixedly connected to the positioning shaft 3, one end of the rod body 432 is movably inserted in the sleeve rod 431, and the other end is fixedly connected to the mounting frame 41. The elastic member 433 is arranged in the sleeve rod 431. The elastic member 433 can be a spring, and its two ends are respectively connected to the sleeve rod 431 and the rod body 432. When the mounting frame 41 approaches the positioning shaft 3, the elastic member 433 will be compressed, and at this time, the elastic member 433 will apply a force to the mounting frame 41 in the direction away from the positioning shaft 3.

[0032] The guide shaft 42 is rotatably connected to the mounting frame 41, and the rotation axis of the guide shaft 42 is parallel to the rotation axis of the positioning shaft 3. The guide shaft 42 can fit with the inner wall of the cylinder body 11, and the axial direction of the positioning shaft 3 and the axial direction of the guide shaft 42 are both vertical. When the guide shaft 42 and the inner wall of the cylinder body 11 are in a fit state, when the positioning shaft 3 is controlled to rotate and drives the guide shaft 42 to move along the inner wall of the cylinder body 11, the guide shaft 42 will rotate.

[0033] like Figures 3 to 5 as well as Fig. 9As shown, the grinding device includes a grinding component 1, which includes a grinding roller 1 511, a rotating member 512, a torsion spring 513 and a driving member 3 514. One end of the rotating member 512 is rotatably mounted on the top of the mounting frame 41. The torsion spring 513 is arranged between the mounting frame 41 and the rotating member 512, and its two ends are respectively fixedly connected to the mounting frame 41 and the rotating member 512. When the rotating member 512 rotates relative to the mounting frame 41, the torsion spring 513 will store force and can apply a reverse force to the rotating member 512. The grinding roller 1 511 is rotatably mounted at the bottom of the other end of the rotating member 512. The grinding roller 1 511 and the guide The driving member 514 is arranged parallel to the shaft 42, and is fixedly installed on the top of the rotating member 512. The driving member 514 can be a motor, and its output end is fixedly connected to the grinding roller 511. The driving member 514 is controlled to operate, and the grinding roller 511 can be driven to rotate. When the guide shaft 42 is controlled to move along the inner wall of the cylinder body 11, the grinding roller 511 can fit with the inner wall of the cylinder body 11 and move along the inner wall of the cylinder body 11. At this time, the driving member 514 is controlled to drive the grinding roller 511 to rotate. The grinding roller 511 in the rotating state can grind the inner wall of the cylinder body 11 and remove burrs on the inner wall of the cylinder body 11.

[0034] like Figures 3 to 5 As shown, the driving component 1 includes a reel 61, a traction rope 62 and a driving member 1 63. The reel 61 is rotatably installed at the bottom of the positioning member 2, and the traction rope 62 is wound around the reel 61. A stopper 1 5121 is fixedly provided on the side wall of the rotating member 512 close to one end of the mounting frame 41, and a lead wire 4311 is fixedly provided on the sleeve rod 431. A lead wire groove is formed between the lead wire 4311 and the sleeve rod 431. The free end of the traction rope 62 passes through the lead wire groove and is fixedly connected to the stopper 1 5121. The driving member 1 63 can be a motor, and its output end is fixedly connected to the reel 61 to control the operation of the driving member 1 63 and drive the reel 61 to rotate, so that the reel 61 can store or release the traction rope 62. When the driving reel 61 rotates to store the traction rope 62, the traction rope 62 will drive the rotating member 512 to rotate and store the torsion spring 513.

[0035] like Figure 3 and Figure 4 As shown, a second stopper 411 is also fixedly provided on the upper part of the mounting frame 41, and the rotating member 512 can rotate under the drive of the torsion spring 513, and until the first stopper 5121 is in contact with the second stopper 411, the second stopper 411 will block the first stopper 5121 to prevent the rotating member 512 from rotating. At this time, the end of the rotating member 512 away from the mounting frame 41 is in the outer direction, that is, the distance between the guide shaft 42 and the positioning shaft 3 is smaller than the distance between the grinding roller 1 511 and the positioning shaft 3.

[0036] Before putting the grinding device into the cylinder body 11, first control the driving member 1 63 to operate, drive the wire wheel 61 to rotate and receive the traction rope 62, the traction rope 62 will drive the rotating member 512 to rotate, and make the grinding roller 1 511 rotate inwardly until the distance between the grinding roller 1 511 and the positioning shaft 3 is smaller than the distance between the guide shaft 42 and the positioning shaft 3. In this process, the torsion spring 513 will accumulate force, and the pulling of the traction rope 62 on the rotating member 512 will also apply an inward force to the rod body 2 432, and the rod body 2 432 will move inwardly, and the mounting frame 41 and the guide shaft 42 will also move inwardly, that is, the guide shaft 42 will be close to the positioning shaft 3, and the elastic member 2 433 will be compressed. When the distance between the guide shaft 42 and the positioning shaft 3 is smaller than the distance between the center of the cylinder body 11 and the side wall, the grinding device can be put into the cylinder body 11, and then control the driving member 1 63 The grinding roller 511 will rotate in the opposite direction with the rotating member 512 until the grinding roller 511 fits the inner wall of the cylinder body 11. At the same time, the rod body 2 432, the mounting frame 41 and the guide shaft 42 will move outward under the action of the elastic member 2 433 until the guide shaft 42 fits the inner wall of the cylinder body 11. Next, the driving member 481 is controlled to operate to drive the positioning shaft 3 to rotate, which can drive the guide shaft 42 and the grinding roller 511 to rotate around the positioning shaft 3, that is, the guide shaft 42 and the grinding roller 511 can move circumferentially along the inner wall of the cylinder body 11. At the same time, the driving member 3 514 is controlled to operate to drive the grinding roller 511 to rotate. At this time, the grinding roller 511 in the rotating state can grind the inner wall of the cylinder body 11 and remove the burrs on the inner wall of the cylinder body 11.

[0037] When the cylinder body 11 is a square structure, during the circumferential movement of the guide shaft 42 along the inner wall of the cylinder body 11, the moving trajectory of the outer end of the guide shaft 42 is also square. Since an elastic telescopic rod 43 is connected between the guide shaft 42 and the positioning shaft 3, during the movement of the guide shaft 42, the distance between the guide shaft 42 and the positioning shaft 3 will be automatically adaptively adjusted. Similarly, the moving trajectory of the grinding roller 511 is also square, and under the action of the torsion spring 513, it can ensure that the grinding roller 511 always remains in close contact with the inner wall of the cylinder body 11, thereby improving the grinding effect.

[0038] like Figures 3 to 5 as well as Figure 8As shown, the grinding device also includes a grinding component 2 and a driving component 2. The positioning shaft 3 is a hollow structure. The positioning shaft 3 includes a sleeve 1 31 and a sleeve 2 32. The sleeve 2 32 is movably inserted in the sleeve 1 31 along the axial direction of the sleeve 1 31. The upper end of the sleeve 1 31 is rotatably connected to the positioning member 2. The gear 5 83 is fixedly installed on the outer peripheral side of the sleeve 1 31. The sleeve rod 2 431 is fixedly connected to the sleeve 1 31. An elastic member 1 33 is provided between the sleeve 1 31 and the sleeve 2 32. The elastic member 1 33 can be a spring. The upper and lower ends thereof are fixedly connected to the sleeve 1 31 and the sleeve 2 32 respectively. When the sleeve 1 31 moves downward relative to the sleeve 2 32, the elastic member 1 33 will be compressed.

[0039] The second grinding assembly includes a support rod 521, a second grinding roller 522, a ring sleeve 523 and a connecting rod 524. The support rod 521 is arranged horizontally, and its inner side end is rotatably inserted into the inner part of the bottom end of the second shaft sleeve 32, and the support rod 521 can rotate relative to the second shaft sleeve 32. The second grinding roller 522 is movably sleeved on the outer peripheral side of the support rod 521, and a limiting groove 5221 is provided on the inner peripheral surface of the second grinding roller 522, and the extension direction of the limiting groove 5221 is in the same direction as the axial direction of the second grinding roller 522. A limiting strip 5211 is fixedly arranged on the support rod 521, and the limiting strip 5211 is slidably fitted in the limiting groove 5221, so that the second grinding roller 522 and the support rod 521 can slide relative to each other, and the second grinding roller 522 and the support rod 521 can rotate synchronously. When grinding, the second grinding roller 522 can fit with the inner bottom surface of the cylinder body 11. At this time, the second grinding roller 522 is controlled to rotate, so that the inner bottom surface of the cylinder body 11 can be grinded. The ring sleeve 523 is rotatably mounted on the outer circumference of the second grinding roller 522. The connecting rod 524 is tilted, one end of which is hinged to the mounting frame 41, and the other end is hinged to the ring sleeve 523, so that when the mounting frame 41 moves downward, the ring sleeve 523 and the second grinding roller 522 can be driven to move inward through the connecting rod 524.

[0040] like Figures 3 to 7As shown, the driving assembly 2 includes a sleeve rod 1 71, a rod body 1 72, a gear 1 73, a gear 2 74 and a driving member 2 75. The sleeve rod 1 71 is arranged in the sleeve 1 31, and its upper end is rotatably connected with the positioning member 2. The rod body 1 72 is arranged in the sleeve 2 32, and its upper end is movably inserted in the sleeve rod 1 71 along the axial direction of the sleeve rod 1 71. The rod body 1 72 and the sleeve rod 1 71 are locked so that the rod body 1 72 and the sleeve rod 1 71 can rotate synchronously. An annular boss 721 is coaxially fixed on the outer circumference of the rod body 1 72, and an annular groove 7211 is provided on the outer circumference of the annular boss 721. An annular protrusion 321 is coaxially fixed on the inner wall of the sleeve 2 32. The shape of the annular protrusion 321 matches the shape of the annular groove 7211, and the annular protrusion 321 is rotatably sleeved in the annular groove 7211. Gear 1 73 is a bevel gear, which is fixedly mounted on the bottom end of rod body 1 72. Gear 2 74 is also a bevel gear, which is located in sleeve 2 32 and fixedly mounted on the inner end of support rod 521. Gear 2 74 meshes with gear 1 73. Driving member 2 75 is fixedly mounted on positioning member 2, and its output end is fixedly connected with sleeve rod 1 71. Driving member 2 75 can be a motor, which controls the operation of driving member 2 75 and can drive sleeve rod 1 71 to rotate. Since rod body 1 72 and sleeve rod 1 71 can rotate synchronously, rod body 1 72 and gear 1 73 can be driven to rotate. Through the meshing of gear 1 73 and gear 2 74, gear 2 74, support rod 521 and grinding roller 2 522 can be driven to rotate, and then the inner bottom surface of cylinder body 11 can be polished by grinding roller 2 522.

[0041] The implementation principle of the casting cylinder deburring device of the embodiment of the present invention is as follows: when grinding the inner wall of the cylinder 11, the cylinder 11 to be ground is first placed on the frame 1, the cylinder 11 is fixed by a fixing structure, and then the grinding device is sent into the cylinder 11 by a mechanical arm. When the height of the cylinder 11 is higher than the height of the grinding roller 511, the upper part of the inner wall of the cylinder 11 is firstly ground by the grinding roller 511. Before starting the grinding, the guide shaft 42 will Under the elastic push of the elastic member 2 433, the grinding roller 1 511 will stop against the inner wall of the cylinder body 11 under the elastic force of the torsion spring 513. Under the action of the elastic member 1 33, the bottom end of the shaft sleeve 2 32 is located at the bottom of the cylinder body 11, and the grinding roller 2 522 stops against the inner bottom surface of the cylinder body 11, and the outer end of the grinding roller 2 522 fits the inner circumferential wall of the cylinder body 11. At this time, the control driving member 4 81 is operated to drive the positioning shaft 3 to rotate, which can drive the guide shaft 42 The guide shaft 42 and the grinding roller 511 rotate around the positioning shaft 3, that is, the guide shaft 42 and the grinding roller 511 can be moved along the circumferential direction of the inner wall of the cylinder body 11. At the same time, the rotation of the positioning shaft 3 will drive the support rod 521 and the grinding roller 522 to rotate around the positioning shaft 3. When the positioning shaft 3 is driven to rotate, the driving member 2 75 and the driving member 3 514 are controlled to operate at the same time. When the driving member 2 75 operates, the sleeve rod 71 can be driven to rotate. It can rotate synchronously, so as to drive the rod body 72 and the gear 1 73 to rotate. Through the meshing of the gear 1 73 and the gear 2 74, the gear 2 74, the support rod 521 and the grinding roller 2 522 can be driven to rotate. The grinding roller 2 522 in the rotating state can grind the inner bottom surface of the cylinder body 11. When the driving member 3 514 is running, the grinding roller 1 511 can be driven to rotate. At this time, the grinding roller 1 511 in the rotating state can grind the inner circumferential wall of the cylinder body 11.

[0042] After the inner circumferential wall and the inner bottom surface of the cylinder body 11 are polished for one cycle by the polishing roller 1 511 and the polishing roller 2 522, the positioning member 2 is controlled to move downward by the mechanical arm, which will drive the sleeve 1 31, the mounting frame 41, the guide shaft 42 and the polishing roller 1 511 to move downward, and the elastic member 1 33 will be compressed until the polishing roller 1 511 moves to the bottom of the cylinder body 11. When the mounting frame 41 moves downward, the annular sleeve 523 and the polishing roller 2 522 are driven to move inwardly through the connecting rod 524. After the polishing roller 1 511 moves to the bottom of the cylinder body 11 and the polishing roller 2 522 moves inwardly a set distance, the driving member 2 75 and the driving member 3 514 are continued to be controlled to operate, and the inner circumferential wall and the inner bottom surface of the cylinder body 11 can continue to be polished respectively by the polishing roller 1 511 and the polishing roller 2 522, so that the polishing is more comprehensive and suitable for cylinder bodies 11 of various sizes.

[0043] It should be noted that when the cylinder body 11 is a square structure, when the outer end of the second grinding roller 522 stops against the inner wall of the cylinder body 11 and rotates around the positioning shaft 3, the moving trajectories of the outer end and the inner end of the second grinding roller 522 are also square. In this way, when the inner bottom surface of the cylinder body 11 is polished, there may be a square area at the center of the inner bottom surface of the cylinder body 11 that cannot be polished by the second grinding roller 522. For this reason, a third grinding roller 525 and a third gear 526 are also provided in the polishing component 2.

[0044] like Figures 2 to 4 As shown, the grinding roller 3 525 is rotatably mounted at the bottom of the positioning shaft 3, and the inner end of the grinding roller 3 525 extends into the interior of the shaft sleeve 2 32. The gear 3 526 is a bevel gear, which is fixedly connected to the inner end of the grinding roller 3 525 and meshes with the gear 1 73. When the control driving member 2 75 is operated to drive the sleeve rod 1 71 and the rod body 1 72 to rotate, the grinding roller 3 525 can be driven to rotate through the meshing of the gear 1 73 and the gear 3 526, so that the central area of ​​the inner bottom surface of the cylinder body 11 can be polished. With the cooperation of the grinding roller 2 522, the grinding effect of the inner bottom surface of the cylinder body 11 is better.
