Description

Technical Field

[0001] This utility model relates to the field of piston processing technology, specifically to a piston polishing machine. Background Technology

[0002] Polishing is an essential step in the piston manufacturing process. It aims to improve the smoothness of the piston's outer peripheral wall, reduce frictional losses, and thus ensure that the piston's reciprocating motion can proceed efficiently and smoothly.

[0003] However, despite the undeniable importance of polishing, the adoption and application of automation technology in piston polishing has lagged behind. Currently, most piston manufacturers still rely on semi-automatic methods to complete polishing tasks. Specifically, workers manually place pistons on the polishing machine, polish them, and then manually remove them to make room for the next piston to be polished. This manual loading and unloading method is not only inefficient but also significantly increases the labor intensity of workers. Prolonged repetitive operations can easily lead to worker fatigue, potentially causing operational errors and affecting the consistency and stability of polishing quality. Furthermore, most existing polishing machines can only polish one piston at a time, further limiting the improvement of production efficiency.

[0004] Given the aforementioned limitations, it is necessary to improve the existing piston polishing machine to achieve automatic loading and unloading of pistons. Utility Model Content

The fixed baffle is fixed on one side of the feeding conveyor line, and the movable baffle is movably provided on the other side of the feeding conveyor line. A conveying port is formed between the fixed baffle and the movable baffle on the feeding conveyor line, and the conveying port is connected to the polishing track.

[0026] The baffle drive is mounted on the frame and is connected to the movable baffle for transmission. The baffle drive is used to drive the movable baffle to move toward or away from the fixed baffle to close or open the conveyor port.

[0027] Further configuration includes, as described above, both the loading and unloading conveyor lines include:

[0028] Two symmetrically arranged conveyor frames form a V-shaped track between the two conveyor frames for conveying the piston. The two side rail walls of the V-shaped track are used to abut against the outer peripheral wall of the piston.

[0029] An adjustment mechanism is mounted on the frame and is connected to one or both conveyor frames via a transmission mechanism. The adjustment mechanism is used to drive the two conveyor frames closer to or further apart from each other.

[0030] Furthermore, the aforementioned adjustment mechanism is mounted on the frame in a height-adjustable manner;

[0031] Both the loading and unloading conveyors also include a lifting mechanism. The lifting mechanism is mounted on the frame, and its output end is connected to the adjustment mechanism and the two conveyor frames.

[0039] In use, the piston polishing machine provided by this utility model continuously feeds pistons one by one into the polishing track via the feeding conveyor line.

[0055] 7. Piston. Detailed Implementation

[0056] 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.

[0057] This utility model provides a piston polishing machine to address the problem of how to improve the production efficiency of pistons 7 and reduce labor intensity.

[0058] See Figure 1 As shown, Figure 1 The image shown is a perspective view of the piston polishing machine in the embodiment. The piston polishing machine includes a frame 1, a polishing device 2, a feeding conveyor line 3, and a discharging conveyor line 4.

[0059] The polishing device 2 is mounted on the frame 1. The polishing device 2 has a polishing track 21 for accommodating a number of pistons 7. The polishing device 2 is used to polish the pistons 7 on the polishing track 21.

[0060] The feeding conveyor line 3 and the unloading conveyor line 4 are both installed on the frame 1. The feeding conveyor line 3 and the unloading conveyor line 4 are respectively connected to the two ends of the polishing track 21. The feeding conveyor line 3 is used to continuously input the pistons 7 one by one into the polishing track 21, so as to push the pistons 7 on the polishing track 21 to continuously input the unloading conveyor line 4 one by one along the polishing track 21.

[0061] When the piston polishing machine of the above technical solution is in use, the feeding conveyor line 3 continuously feeds the pistons 7 one by one into the polishing track 21. As the pistons 7 are continuously fed into the polishing track 21, they are pushed to move along the polishing track 21, thus being continuously fed into the unloading conveyor line 4. During the movement of the pistons 7 along the polishing track 21, the polishing device 2 polishes all the pistons 7 on the polishing track 21 simultaneously. It can be seen that this piston polishing machine can realize the automatic and continuous feeding and unloading of pistons 7 through the feeding conveyor line 3 and the unloading conveyor line 4, and can simultaneously polish several pistons 7 on the polishing track 21 in batches through the polishing device 2, thereby effectively improving the production efficiency of pistons 7 and reducing labor intensity.

[0062] See Figure 1 As shown, the piston polishing machine also includes a material tray 5 and a feeding device 6. The material tray 5 is fixed to the frame 1 by screwing or welding, and is located on one side of the feeding conveyor line 3. The material tray 5 has a material trough 51 for batch loading of pistons 7. The feeding device 6 is installed on the frame 1 and is used to transport the pistons 7 in the material trough 51 to the feeding conveyor line 3. In this way, the operator only needs to pour the pistons 7 in batches onto the material tray 5, and the feeding device 6 can automatically transport the pistons 7 to the feeding conveyor line 3. In cooperation with the feeding conveyor line 3, the pistons 7 are continuously fed into the polishing track 21 for polishing one by one. There is no need for manual loading of each piston, which greatly reduces the dependence on manual labor, reduces labor intensity, and improves the production efficiency of pistons 7.

[0063] See Figure 1 , Figure 2 and Figure 5 As shown, Figure 2 for Figure 1 Enlarged diagram of point A in the middle. Figure 5This is a partial structural diagram of the feeding conveyor line, material tray, and feeding device in an embodiment. In one embodiment of the feeding device 6, the feeding device 6 includes a feeding block 61 and a feeding block drive member 62. A clearance opening 511 is provided at the bottom of the material trough 51 near the feeding conveyor line 3, and the feeding block 61 can be raised and lowered to be positioned at the clearance opening 511 of the material tray 5. The feeding block 61 includes a material-carrying surface 611 for supporting a piston 7. The length direction of the material-carrying surface 611 is parallel to the feeding conveyor line 3, and the length of the material-carrying surface 611 is not less than the length of a single piston 7, and the width of the material-carrying surface 611 is not less than the radius of the piston 7, to ensure that the material-carrying surface 611 can support at least one piston 7. The feeding block drive member 62 is mounted on the frame 1 by screwing or welding and is drively connected to the feeding block 61. The feeding block drive member 62 is used to drive the feeding block 61 to move up and down between a first position and a second position. In the first position, the loading block 61 has its loading surface 611 inside the clearance opening 511. In the second position, the loading block 61 penetrates and blocks the clearance opening 511, with its loading surface 611 outside the trough 51 and opposite to the loading conveyor line 3. Thus, with the loading block 61 initially in the first position, some pistons 7 inside the trough 51 move to the loading surface 611 of the clearance opening 511. When the loading block drive 62 drives the loading block 61 to rise from the first position to the second position, the loading block 61 pulls the pistons 7 on the loading surface 611 upwards, thereby conveying the pistons 7 to the loading conveyor line 3. Simultaneously, the loading block 61 blocks the clearance opening 511, preventing the remaining pistons 7 inside the trough 51 from falling out of the clearance opening 511 and causing waste.

[0064] The aforementioned loading block drive 62 can use existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles. Its output end is connected to the loading block 61 by means of screwing or welding. In this way, when the loading block drive 62 extends, the loading block 61 can be raised to the second position; conversely, when the loading block drive 62 shortens, the loading block 61 can be lowered back to the first position.

[0065] The length of the material-carrying surface 611 can be much greater than the length of the piston 7, and the width of the material-carrying surface 611 can also be greater than the diameter of the piston 7. In this way, the material-carrying surface 611 can load multiple pistons 7 in one lifting and lowering operation, thereby realizing batch loading of the material-carrying conveyor line 3 and further improving production efficiency.

[0066] See Figure 5As shown, based on the above embodiment, both the bottom surface of the trough 51 and the material-carrying surface 611 extend downwards at an incline toward the feeding conveyor line 3. The distance between the material-carrying surface 611 and the trough wall of the trough 51 near the feeding conveyor line 3 is no greater than the radius of the piston 7. Thus, when the workers pour the pistons 7 in batches onto the material tray 5, the bottom surface of the material trough 51 tilts downwards, which can guide the pistons 7 in the material tray 5 to move toward the loading surface 611 of the relief port 511, so as to move some of the pistons 7 in the material trough 51 onto the loading surface 611; then, the loading block drive 62 drives the loading block 61 to rise from the first position to the second position. During this rising process, the tilted loading surface 611 and the trough wall of the material trough 51 near the loading conveyor line 3 can stably load the pistons 7, so that the loading block 61 drives the pistons 7 on the loading surface 611 to rise together until the loading surface 611 is outside the material trough 51 and separates from the trough wall of the material trough 51. At the same time, the pistons 7 on the loading surface 611 can move toward the loading conveyor line 3 along the tilt direction of the loading surface 611, so as to be conveyed onto the loading conveyor line 3.

[0067] See Figure 2 and Figure 5 As shown, based on the above embodiment, a guide plate 52 is provided on the outer wall of the material tray 5 facing the feeding conveyor line 3 by means of integral connection or welding. When the feeding block 61 is in the second position, the material-carrying surface 611 is opposite to one side of the guide plate 52, and the other side of the guide plate 52 is inclined downward and opposite to the feeding conveyor line 3. In this way, the guide plate 52 can assist the material-carrying surface 611 in guiding the piston 7 into the feeding conveyor line 3, effectively ensuring that the piston 7 on the material-carrying surface 611 is conveyed to the feeding conveyor line 3.

[0068] See Figure 2 and Figure 5 As shown, based on the embodiment of the feeding device 6 described above, the feeding device 6 further includes a pusher plate 63 and a pusher plate drive member 64. The pusher plate 63 is movably located on the feeding conveyor line 3. The pusher plate drive member 64 is mounted on the frame 1 by means of screwing or welding, and is drively connected to the pusher plate 63. The pusher plate drive member 64 is used to drive the pusher plate 63 to move along the feeding conveyor line 3. Thus, when the pusher plate drive member 64 drives the pusher plate 63 to move along the conveying direction of the feeding conveyor line 3, it can assist the feeding conveyor line 3 in conveying the piston 7.

[0069] The aforementioned push plate drive component 64 can use existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles. Its output end is connected to the push plate 63 by means of screwing or welding. In this way, when the push plate drive component 64 extends, the push plate 63 can move along the conveying direction of the feeding conveyor line 3.

[0070] See Figure 1 and Figure 3 As shown, Figure 3 for Figure 1The enlarged schematic diagram at point B shows that, based on the embodiment of the feeding device 6 described above, the feeding device 6 further includes a fixed baffle 65, a movable baffle 66, and a baffle drive component 67. The fixed baffle 65 is fixed to one side of the feeding conveyor line 3 by means of screwing or welding, while the movable baffle 66 is movably located on the other side of the feeding conveyor line 3. A conveying port 68 is formed on the feeding conveyor line 3 between the fixed baffle 65 and the movable baffle 66, and the conveying port 68 is connected to the polishing track 21. The baffle drive component 67 is mounted on the frame 1 by means of screwing or welding and is drively connected to the movable baffle 66. The baffle drive component 67 is used to drive the movable baffle 66 to move toward or away from the fixed baffle 65 to close or open the conveying port 68. Thus, the baffle drive 67 drives the movable baffle 66 to move toward the fixed baffle 65, which can close the conveying port 68 and prevent the feeding conveyor line 3 from continuing to feed the piston 7 to the polishing track 21; conversely, the baffle drive 67 drives the movable baffle 66 to move away from the fixed baffle 65, which can open the conveying port 68 so that the feeding conveyor line 3 can continue to feed the piston 7 to the polishing track 21.

[0071] The aforementioned baffle drive 67 can use existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles. Its output end is connected to the movable baffle 66 by screwing or welding. In this way, when the baffle drive 67 extends, the movable baffle 66 can be moved onto the feeding conveyor line 3 and the conveying port 68 can be closed. Conversely, when the baffle drive 67 shortens, the movable baffle 66 can be moved away from the feeding conveyor line 3 and the conveying port 68 can be opened.

[0072] See Figure 1 , Figure 4 and Figure 6 As shown, Figure 4 for Figure 1 Enlarged diagram of point C in the middle. Figure 6 This is a partial structural diagram of the feeding conveyor line in one embodiment. In one implementation of the feeding conveyor line 3 and the unloading conveyor line 4, both the feeding conveyor line 3 and the unloading conveyor line 4 include an adjusting mechanism 31 and two symmetrically distributed conveyor frames 32. A V-shaped track 33 for conveying the piston 7 is formed between the two conveyor frames 32, and the two side walls of the V-shaped track 33 are used to abut against the outer peripheral wall of the piston 7. The adjusting mechanism 31 is mounted on the frame 1 and is drivenly connected to one or both conveyor frames 32. The adjusting mechanism 31 is used to drive the two conveyor frames 32 closer to or further apart from each other to adjust the axial position of the piston 7 on the V-shaped track 33. In this way, the V-shaped track 33 can be adjusted according to the actual diameter of the piston 7 to keep the axial position of pistons 7 of different diameters on the V-shaped track 33 unchanged, so as to achieve the best actual polishing effect. Thus, this piston polishing machine can be used to polish pistons 7 of different diameters, with a wide range of applications.

[0073] The inner side of the aforementioned conveyor frame 32 can be equipped with existing motor-conveyor belt or motor-conveyor chain conveyor structures to convey the piston 7 on the V-shaped track 33.

[0074] The aforementioned adjustment mechanism 31 is mounted on the frame 1 by means of screwing or welding, or it can be slidably mounted on the frame 1 in a height-adjustable manner.

[0075] See Figure 4 and Figure 6 As shown, based on the above embodiment, both the loading conveyor line 3 and the unloading conveyor line 4 further include a lifting mechanism 34. The adjusting mechanism 31 is slidably mounted on the frame 1, and the lifting mechanism 34 is mounted on the frame 1 by means of screws or welding. The output end of the lifting mechanism 34 is connected to the adjusting mechanism 31 and the two conveyor frames 32. The lifting mechanism 34 is used to drive the adjusting mechanism 31 and the two conveyor frames 32 to move up and down. Thus, the lifting mechanism 34 can drive the adjusting mechanism 31 and the two conveyor frames 32 to move up and down, thereby driving the loading conveyor line 3 or the unloading conveyor line 4 to move up and down, adjusting the height of the loading conveyor line 3 and the unloading conveyor line 4 so that they are respectively connected to both ends of the polishing track 21.

[0076] The aforementioned lifting mechanism 34 can use existing reversing lifting moving components.

[0077] The aforementioned adjusting mechanism 31 can use an existing one-way screw and nut moving assembly, connected together with one of the conveyor frames 32 to the output end of the lifting mechanism 34 or the frame 1 via screwing or welding. The other conveyor frame 32 is slidably connected to the output end of the lifting mechanism 34 or the frame 1, and connected to the output end of the adjusting mechanism 31 via screwing or welding. Alternatively, the aforementioned adjusting mechanism 31 can use an existing two-way screw and nut moving assembly, where both conveyor frames 32 can be slidably connected to the output end of the lifting mechanism 34 or the frame 1, and both connected to the output end of the adjusting mechanism 31 via screwing or welding. In both methods, the adjusting mechanism 31 can drive the two conveyor frames 32 to move closer or further apart.

[0078] See Figure 1 and Figure 7 As shown, Figure 7The diagram illustrates the structure of the polishing apparatus in one embodiment. The polishing apparatus 2 includes a brush wheel 22, a guide wheel 23, a brush wheel drive mechanism 24, and a guide wheel drive mechanism 25. The brush wheel 22 and guide wheel 23 are positioned opposite each other, forming the aforementioned polishing track 21 between them. Both the brush wheel drive mechanism 24 and the guide wheel drive mechanism 25 are mounted on the frame 1. The brush wheel drive mechanism 24 is driven by the brush wheel 22 and drives the brush wheel 22 to rotate, polishing the piston 7 on the polishing track 21. The guide wheel drive mechanism 25 is driven by the guide wheel 23 and drives the guide wheel 23 to rotate, so that the guide wheel 23 rotates in the opposite direction to the brush wheel 22. Thus, while the brush wheel drive mechanism 24 drives the brush wheel 22 to rotate forward to polish the piston 7 on the polishing track 21, the guide wheel drive mechanism 25 drives the guide wheel 23 to rotate in the opposite direction, using dynamic friction to prevent the piston 7 from rotating out of the polishing track 21 with the brush wheel 22.

[0079] Both the brush wheel drive mechanism 24 and the guide wheel drive mechanism 25 can use existing rotary drive mechanisms such as motor-belt reducers or motor-gear reducers. Their output ends are connected to the brush wheel 22 and the guide wheel 23 respectively by screwing or welding.

[0080] The brush wheel drive mechanism 24 and guide wheel drive mechanism 25 can be directly fixedly installed on the frame 1, or they can be movably installed on the frame 1.

[0081] See Figure 7 As shown, in one installation method of the brush wheel drive mechanism 24 and the guide wheel drive mechanism 25, both the brush wheel drive mechanism 24 and the guide wheel drive mechanism 25 are slidably mounted on the frame 1. The polishing device 2 also includes two position adjustment mechanisms 26. The position adjustment mechanisms 26 are mounted on the frame 1 by means of screwing or welding, and the two position adjustment mechanisms 26 are respectively connected to the brush wheel drive mechanism 24 and the guide wheel drive mechanism 25 for driving the brush wheel drive mechanism 24 and the guide wheel drive mechanism 25 to move closer to each other or further away from each other. In this way, the polishing track 21 can be adjusted to match the piston 7 according to the actual diameter of the piston 7 being polished, thereby adjusting the polishing effect.

[0082] The aforementioned position adjustment mechanism 26 can use existing linear displacement drive mechanisms such as lead screw and nut linear modules. The output ends of the two position adjustment mechanisms 26 are respectively connected to the brush wheel drive mechanism 24 and the guide wheel drive mechanism 25 by means of screwing or welding.

[0083] See Figure 8 As shown, Figure 8The diagram illustrates the structure of the guide frame and collection box in this embodiment. Based on the embodiments of the brush wheel 22 and guide wheel 23 described above, the frame 1 is further equipped with a guide frame 11 and a collection box 12 via screwing or welding. The guide frame 11 is mounted on the frame 1 via screwing or welding and is located below the polishing track 21. The guide frame 11 has a guide surface 111, which extends downwards at an angle towards the collection box 12. Thus, if the polishing track 21 is not compatible with the piston 7, causing the piston 7 to detach from the polishing track 21, the piston 7 will fall into the collection box 12 along the guide surface 111 instead of falling out of place, greatly facilitating centralized processing by the staff.

[0084] See Figure 8 As shown, based on the above embodiment, the frame 1 is also provided with a dust suction funnel 13 by means of screwing or welding. The dust suction funnel 13 is located below the polishing track 21 and is used to suck up the dust generated during polishing, thereby improving the polishing effect.

[0085] The aforementioned vacuum funnel 13 can be connected to an existing vacuum cleaner to achieve a vacuuming effect.
