Description

Technical Field

[0001] This utility model relates to a grinding device, specifically a piston rod grinding device, belonging to the technical field of piston processing equipment. Background Technology

[0002] Piston rod grinding equipment is used for grinding and polishing the outer surface of piston rods. During the production and processing of piston rods, the outer surface may have defects such as burrs, tool marks, scratches, and oxide scale. These defects affect the surface quality and performance of the piston rod. The outer surface grinding machine can remove these defects, making the outer surface of the piston rod smoother and flatter, improving its surface quality, thereby reducing wear, increasing the wear resistance of the piston rod, extending its service life, and reducing equipment maintenance costs. The smooth outer surface of the piston rod can also make the plating or coating more uniform and firm, improving the effect and quality of surface treatment.

[0003] Most existing piston rod grinding equipment uses grinding wheels or grinding wheel belts to grind piston rods. When supporting the grinding wheel belt, these machines often use support rollers to maintain tension. However, to facilitate grinding wheel belt replacement, one side of the support roller is left unsupported, creating resistance when the grinding wheel belt contacts the piston rod. Over time, this can cause deformation on the unsupported side of the support roller, leading to eccentric support of the grinding wheel belt. This reduces the contact area between the grinding wheel belt and the piston rod, lowering grinding efficiency and accuracy. Therefore, we provide a piston rod grinding device to solve these problems. Utility Model Content

A slide block is disposed above the support seat, and a rotating roller and a support roller are rotatably connected to the inner wall of the slide block. The rotating roller and the support roller are symmetrical. A grinding wheel belt is sleeved on the outside of the rotating roller and the support roller. The outer surface of the grinding wheel belt is in contact with the outer surface of the piston rod body. A tension roller is provided inside the grinding wheel belt. A second motor is installed on one side of the slide block. The output shaft of the second motor is connected to one end of the rotating roller. A first slide rail is connected to the upper surface of the slide block. A support plate is slidably connected to the outer surface of the first slide rail. The inner wall of the support plate is rotatably connected to the end of the rotating roller and the support roller away from the slide block.

[0006] Preferably, one end of the first lead screw is connected to one side of the slide, the upper surface of the slide is connected to an ear seat, the other end of the first lead screw is rotatably connected to the inner wall of the ear seat, and the end of the first lead screw located outside the slide is connected to a first handwheel.

[0007] Preferably, both the slide block and the support plate have slide tracks on their inner sides. A support block is slidably connected to the inner wall of the slide track. The inner wall of the support block is rotatably connected to the end of the tension roller. A second lead screw is rotatably connected to the outer surface of the support block. The outer surface of the second lead screw is threadedly connected to the inner wall of the support plate and the slide block. A second handwheel is connected to the top end of the second lead screw.

[0008] Preferably, the upper surface of the support base is connected to a second slide rail, and the outer surface of the second slide rail is slidably connected to the inner wall of the slide base.

[0009] Preferably, a third lead screw is rotatably connected to the inner wall of the support base, the outer surface of the third lead screw is connected to the threaded seat on the inner wall of the slide, and a third handwheel is connected to one end of the third lead screw located outside the support base.

[0010] Preferably, a fourth lead screw is rotatably connected to the inner wall of the carriage, a third motor is installed on one side of the worktable, and the output shaft of the third motor is connected to one end of the fourth lead screw.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This piston rod grinding equipment utilizes the cooperation between a support plate, a first lead screw, and a first slide rail. The first slide rail maintains the stability of the support plate during its movement. The rotation of the first lead screw generates a driving force, providing power for the support plate to move. This force propels the support plate away from and towards the rotating roller and the support roller. After the support plate moves away from the rotating roller and the support roller, a gap exists between the support plate and the slide block, allowing space for the grinding wheel belt to be replaced. After the support plate contacts the support roller and the rotating roller, it supports the suspended end of the support roller and the rotating roller, providing stability to the support roller. This allows the support roller to provide more stable support for the grinding wheel belt, maintaining the contact area between the grinding wheel belt and the piston rod, thus improving grinding efficiency and precision.

[0014] 2. This piston rod grinding equipment uses the cooperation between the support block and the second lead screw to generate a driving force through the rotation of the second lead screw, which provides power for the support block to move. After the support block moves, the position of the tension roller is changed. By moving the position of the tension roller, the tension of the grinding wheel belt is adjusted to prevent the grinding wheel belt from becoming loose due to insufficient tension, which would prevent the power from being transmitted effectively. Moving the position of the tension roller improves the stability of the grinding wheel belt. Attached Figure Description

The output shaft of the first motor 13 is connected to one end of the transmission shaft 4. The gripper 2 is installed on the other end of the transmission shaft 4. A piston rod body 5 is provided inside the gripper 2. The first motor 13 is used as a power source to drive the gripper 2 to rotate. The gripper 2 fixes the piston rod body 5. When the gripper 2 rotates, it drives the piston rod body 5 to rotate at the same time.

[0023] The upper surface of the worktable 1 is connected to a slide 6, which supports the support base 7 and maintains the stability of the support base 7 when it moves. The position of the grinding wheel belt 11 is changed when the support base 7 moves.

[0024] A support seat 7 is slidably connected to the inner wall of the slide 6. A slide 8 is provided above the support seat 7. A rotating roller 9 and a support roller 10 are rotatably connected to the inner wall of the slide 8. The transmission roller and the support roller 10 are symmetrical. A grinding wheel belt 11 is sleeved on the outside of the rotating roller 9 and the support roller 10. The outer surface of the grinding wheel belt 11 is in contact with the outer surface of the piston rod body 5. The grinding wheel belt 11 is supported by the support roller 10 and the rotating roller 9 to maintain the stability of the grinding wheel belt 11 during rotation. A second motor 27 is installed on one side of the slide 8. The output shaft of the second motor 27 is connected to one end of the rotating roller 9. The second motor 27 is the power source to provide power for the rotation of the rotating roller 9. When the rotating roller 9 rotates, it drives the grinding wheel belt 11 to rotate at the same time. After the grinding wheel belt 11 rotates, it has the power to grind the piston rod body 5.

[0025] The upper surface of the slide block 8 is connected to a first slide rail 14, and the outer surface of the first slide rail 14 is slidably connected to a support plate 15. The inner wall of the support plate 15 is rotatably connected to the end of the rotating roller 9 and the support roller 10 away from the slide block 8. The inner wall of the support plate 15 is threadedly connected to a first lead screw 16. The first slide rail 14 maintains the stability of the slide block 8 when it moves. The rotation of the first lead screw 16 generates a push, which pushes the slide block 8 to move to a new position. After the slide block 8 moves to a new position, the contact distance between the grinding wheel belt 11 and the piston rod is changed.

[0026] One end of the first lead screw 16 is connected to one side of the slide block 8. The upper surface of the slide block 8 is connected to the ear seat 17. The other end of the first lead screw 16 is rotatably connected to the inner wall of the ear seat 17. The end of the first lead screw 16 located outside the slide block 8 is connected to the first handwheel 18. The pushing force generated by the rotation of the first lead screw 16 provides the pushing force for the support plate 15 to move. The first handwheel 18, the second handwheel 22 and the third handwheel 25 are only used to increase the contact area between the hand and the first lead screw 16, the second lead screw 21 and the third lead screw 24, so as to facilitate the hand to exert force.

[0027] The grinding wheel belt 11 is equipped with a tension roller 12 inside. The inner sides of the slide block 8 and the support plate 15 are provided with slide rails 19. The inner wall of the slide rail 19 is slidably connected to a support block 20. The inner wall of the support block 20 is rotatably connected to the end of the tension roller 12.

The outer surface of the second lead screw 21 is threadedly connected to the inner wall of the support plate 15 and the slide block 8. The top end of the second lead screw 21 is connected to a second handwheel 22. There are a total of two support blocks 20, two lead screws 21 and two handwheels 22, which correspond to the slide rails 19 respectively. The rotation of the second lead screw 21 generates a driving force, which provides power for the support block 20 to move. After the support block 20 moves, the position of the tension roller 12 is changed. The tension of the grinding wheel belt 11 is adjusted by moving the position of the tension roller 12.

[0028] The upper surface of the support base 7 is connected to a second slide rail 23. The outer surface of the second slide rail 23 is slidably connected to the inner wall of the slide block 8. The second slide rail 23 guides and supports the slide block 8, maintaining its stability when it moves. The inner wall of the support base 7 is rotatably connected to a third lead screw 24. The outer surface of the third lead screw 24 is connected to a threaded seat on the inner wall of the slide block 8. The end of the third lead screw 24 located outside the support base 7 is connected to a third handwheel 25. Rotating the third lead screw 24 generates a pushing force, which pushes the slide block 8 to move. After the slide block 8 moves, the contact distance between the grinding wheel belt 11 and the piston rod body 5 is changed.

[0029] The inner wall of the slide 6 is rotatably connected to the fourth lead screw 26. A third motor 31 is installed on one side of the worktable 1. The output shaft of the third motor 31 is connected to one end of the fourth lead screw 26. The third motor 31 serves as the power source to provide power for the rotation of the fourth lead screw 26. After the fourth lead screw 26 rotates, it pushes the support seat 7 to move.

[0030] The upper surface of the worktable 1 is connected to a third slide rail 28, and a sliding seat 29 is slidably connected to the outer surface of the third slide rail 28. A center 30 is installed inside the sliding seat 29. The end of the center 30 contacts the end of the piston rod body 5 away from the gripper 2. The center 30 supports the other end of the piston rod body 5 to maintain the stability of the piston rod body 5. The third slide rail 28 guides and supports the sliding seat 29 to maintain the stability of the sliding seat 29 when it moves. The center 30 is a commonly used mechanical component. By rotating the handwheel at the rear, the center 30 is pushed to move, so that the center 30 and the piston rod body 5 maintain close contact. A locking bolt is provided inside the sliding seat 29. By rotating the locking bolt, the movement of the sliding seat 29 is restricted. At the same time, flipping the locking bolt releases the restriction on the sliding seat 29.

[0031] In use, the present invention is as follows: First, the grinding wheel belt 11 is fitted over the support roller 10, the rotating roller 9, and the tension roller 12. Then, the first lead screw 16 is rotated to push the support plate 15 to move. The support plate 15 then contacts the support roller 10 and the rotating roller 9. One end of the tension roller 12 is inserted into the support block 20. Then, the second lead screw 21 inside the rotating support plate 15 and the slide block 8 rotates. After the second lead screw 21 rotates, it pushes the support block 20 to move. The support block 20 pushes the tension roller 12 to move, thus adjusting the tension of the grinding wheel belt 11. Then, the slide block 8 can be moved to drive the grinding wheel belt 11 to contact the piston rod body 5, so that the grinding wheel belt 11 grinds the piston rod body 5.
