Description

Technical Field

[0001] This application relates to the field of polishing machine technology, and in particular to a piston rod polishing auxiliary clamping device. Background Technology

[0002] With the technological upgrading in fields such as machinery manufacturing and automobiles, the surface quality of workpieces is a key indicator that directly affects product performance, lifespan, and safety.

[0003] However, the piston rod is conveyed to the polishing machine via a conveyor table. While the piston rod is rotating and moving, the polishing wheel polishes the moving piston rod on one side. At this time, the position of the polishing wheel is not fixed, but the piston rod may resonate and vibrate during the movement, resulting in uneven polishing. Utility Model Content

[0004] The purpose of this application is to provide a piston rod polishing auxiliary clamping device, which has the advantages of improving polishing accuracy. It solves the problem that when the piston rod is conveyed to the polishing machine by the conveyor table, the polishing wheel polishes the moving piston rod on one side while the piston rod is rotating and moving. At this time, the position of the polishing wheel is not fixed, but the piston rod may resonate and vibrate during the movement, resulting in uneven polishing.

[0005] This application provides a piston rod polishing auxiliary clamping device with the following technical solution: A piston rod polishing auxiliary clamping device includes a polishing machine and a support frame. Two rotating seats arranged in a mirror image are fixedly connected to the upper end of the support frame. A transmission roller is rotatably connected inside the two rotating seats. Multiple transmission wheels arranged in a linear array are fixedly connected to the outer wall of the transmission roller. A motor is fixedly connected to one side of the upper end of the support frame. Multiple auxiliary wheels arranged in a linear array are fixedly connected to the side of the upper end of the support frame away from the transmission roller. Four supports arranged in a linear array are fixedly connected to the upper end of the support frame. Two sliding rods arranged in a mirror image are slidably arranged inside the upper end of each of the four supports. Two pairs of sliding rods are fixedly connected to a second rotating seat at one end of each support. A pressure roller is rotatably connected inside each of the four second rotating seats. Two springs arranged in a mirror image are fixedly connected to the upper end of each of the four supports. A fixing plate is fixedly connected to the upper end of each pair of springs. The support frame passes through the polishing machine.

[0006] By adopting the above technical solution, the transmission roller on the support frame works in conjunction with the motor. When the motor drives the transmission roller to rotate, multiple transmission wheels on the outer wall of the transmission roller rotate synchronously, providing stable conveying power to the piston rod and ensuring that the piston rod can move at a uniform speed. At the same time, multiple auxiliary wheels on the side of the support frame away from the transmission roller limit the piston rod from the side, preventing it from shifting laterally during movement. The pressure rollers on the four supports form an elastic pressure structure through slide rods and springs. The elastic force of the springs ensures that the pressure rollers always fit against the surface of the piston rod, providing sufficient clamping force. The holding force prevents the piston rod from resonating and vibrating during polishing, and can automatically adjust the holding force according to the diameter of the piston rod to avoid damage to the piston rod caused by rigid clamping. When the piston rod moves and polishes in the polishing machine, the lateral limiting of the auxiliary wheel and the elastic holding of the holding roller work together to stably constrain the piston rod from multiple directions, suppressing the resonance and vibration that may occur during the rotation and movement of the piston rod. This allows the piston rod to maintain a stable posture and uniform movement when passing through the polishing machine, thereby making the polishing wheel polish the piston rod more evenly and improving the polishing accuracy of the piston rod.

[0007] Preferably, a feeding device is fixedly installed on one side of the support frame, and a receiving device is fixedly installed at the end of the support frame away from the feeding device.

[0008] By adopting the above technical solution, a complete process from workpiece loading to collection after processing is formed by fixing a feeding device on one side of the support frame and a receiving device on the other side away from the feeding device. This reduces manual intervention and improves overall processing efficiency. During operation, the piston rod to be polished can be placed in the feeding device, which then orderly conveys the piston rods one by one to the transmission wheel of the support frame, ensuring that the piston rods can stably enter the subsequent clamping and polishing stages. After the piston rods are polished in the polishing machine, they are moved out from the other end of the support frame by the transmission wheel. At this time, the receiving device can promptly receive the polished piston rods, avoiding random stacking of the finished piston rods, which could cause surface scratches or chaos. Throughout the process, the feeding device and the receiving device respectively undertake the auxiliary work of loading and unloading, making the polishing of the piston rods a continuous operation, ensuring the accuracy of loading and the orderliness of unloading, and further improving the efficiency and standardization of the overall polishing process.

[0009] Preferably, the feeding device includes a feeding frame, with a plurality of first baffles arranged in a linear array fixedly connected to one side of the upper end of the feeding frame, and four first mounting plates arranged in a linear array fixedly connected to the bottom end of one side of the feeding frame. Each of the four first mounting plates is fixedly connected to a first fixed seat, and each of the four first fixed seats is fixedly connected to a first pneumatic push rod. The telescopic ends of the four first pneumatic push rods are fixedly connected to a first lifting frame, and a second baffle is fixedly connected to one side of the upper end of the first lifting frame.

[0010] By adopting the above technical solution, orderly feeding is achieved through the setting of a feeding rack, a first baffle, a first pneumatic push rod, a first lifting frame, and a second baffle. The feeding rack provides a space for the piston rods to be polished, and the multiple first baffles at its upper end can separate the piston rods, preventing them from squeezing and colliding with each other on the feeding rack. The first mounting plate and the first fixed seat at the bottom of one side of the feeding rack provide a stable mounting base for the first pneumatic push rod. During operation, the first pneumatic push rod extends and retracts, driving the first lifting frame to move up and down. When the first lifting frame rises, the upper side of the lifting frame will lift the piston rods on the feeding rack, allowing the bottommost piston rod to smoothly detach from the feeding rack and enter the transmission wheel of the support frame. The feeding device can transport the piston rods one by one to the processing area, ensuring that each piston rod can accurately enter the clamping and polishing stage, reducing the tediousness of manual feeding, improving the stability and efficiency of feeding, and providing an orderly material supply guarantee for subsequent polishing processing.

[0011] Preferably, the receiving device includes a receiving frame, four second mounting plates arranged in a linear array are fixedly connected to one side of the bottom of the receiving frame, a second fixed seat is fixedly connected to one side of each of the four second mounting plates, a second pneumatic push rod is fixedly connected inside each of the four second fixed seats, a second lifting frame is fixedly connected to the telescopic ends of each of the four second pneumatic push rods, four third baffles arranged in a linear array are fixedly connected to one side of the upper end of the second lifting frame, four fourth baffles arranged in a linear array are fixedly connected to the upper end of the second lifting frame away from the third baffles, and three top blocks arranged in a linear array are fixedly connected to the upper end of the receiving frame.

[0012] By adopting the above technical solution, the polished piston rods are collected in an orderly manner by setting up a receiving rack, a second pneumatic push rod, a second lifting frame, a third baffle, a fourth baffle, and a top block. The receiving rack provides storage space for the finished piston rods, and the second mounting plate and the second fixed seat at its bottom provide stable installation support for the second pneumatic push rod. During operation, when the polished piston rods are transported to the receiving device, the second pneumatic push rod extends and retracts, driving the second lifting frame to move up and down. When the second lifting frame rises, the third baffle on it lifts the polished piston rods and rolls them to the side of the fourth baffle. Then, the second pneumatic push rod retracts, and the top block guides the piston rods so that they can accurately and smoothly enter the receiving rack. Through this coordination, the receiving device can collect the polished piston rods in an orderly and neat manner, preventing surface damage or chaos caused by random stacking of piston rods, ensuring the integrity of the finished product, reducing the amount of manual sorting work, and further improving the efficiency and standardization of the entire processing flow.

[0013] Preferably, the output end of the motor is fixedly connected to the transmission roller via a coupling.

[0014] By adopting the above technical solution, the output end of the motor is fixedly connected to the transmission roller through a coupling, so that the motor can stably transmit power to the transmission roller. After the motor starts, the rotational motion of its output end is accurately transmitted to the transmission roller through the coupling, driving the transmission roller and the transmission wheel on the outer wall to rotate synchronously, thereby providing continuous and stable power for the conveying of the piston rod, ensuring that the piston rod can move smoothly at the preset speed, thus ensuring the uniformity of the piston rod's movement during the polishing process, and providing a reliable power guarantee for improving the polishing accuracy.

[0015] Preferably, all of the auxiliary wheels are inclined.

[0016] By adopting the above technical solution, multiple auxiliary wheels are all set at an angle, which can effectively limit the movement of the piston rod from the side. When the piston rod is driven by the transmission wheel and moves forward through the angled auxiliary wheels, it ensures that the piston rod always moves smoothly along the preset path, thereby ensuring the stability of the polishing process and helping to further improve the uniformity of polishing.

[0017] Preferably, the upper end of the feed rack is inclined.

[0018] By adopting the above technical solution, the upper end of the feeding rack is inclined. The piston rods placed on the feeding rack will naturally slide downwards under their own gravity, achieving initial positioning without the need for an additional power source. After the piston rods at the lower end are transported to the processing area, the piston rods at the upper end will automatically replenish downwards under gravity. Combined with the separating effect of the first baffle, the piston rods can always maintain an orderly arrangement, avoiding accumulation or jamming, reducing the need for manual intervention, and ensuring that the feeding device can continuously and stably provide piston rods to be polished for subsequent processing stages, thereby improving the overall feeding efficiency.

[0019] Preferably, the upper end of the receiving rack is inclined.

[0020] By adopting the above technical solution, the upper end of the receiving rack is inclined, which can guide the polished piston rod to move and return to its position automatically with the help of gravity. After the piston rod is transported from the support frame to the receiving rack, it will slide naturally downward along the inclined direction of the receiving rack. With the limiting effect of the third and fourth baffles, the piston rod can be prevented from shifting or piling up on the receiving rack. This allows the finished piston rods to be arranged in an orderly manner in the receiving rack without the need for manual sorting and placement. It also prevents surface scratches that may be caused by disorderly stacking of piston rods, and ensures that the receiving process is smooth and unobstructed. This provides convenience for the centralized transfer of finished products and further improves the continuity and efficiency of the entire polishing process.

[0021] In summary, this application includes the following beneficial technical effects: This piston rod polishing auxiliary clamping device uses a support frame as the base carrier. A motor drives the transmission rollers and transmission wheels to rotate via a coupling, providing stable conveying power to the piston rod. Simultaneously, an inclined auxiliary wheel moves the piston rod forward, while a spring- and slide-driven pressure roller provides elastic pressure, constraining the piston rod from multiple directions. This effectively suppresses resonance vibration during polishing, ensuring polishing uniformity and precision. Feeding and receiving devices are located on both sides of the support frame, forming an auxiliary system. The inclined design of the feeding frame, combined with a first baffle, a pneumatically driven lifting frame, and a second baffle, ensures orderly feeding of the piston rod. The inclined design of the receiving frame, combined with a third baffle, a fourth baffle, a top block, and a pneumatically driven lifting frame, completes the neat collection of the polished piston rod. This device solves the machining accuracy problem caused by piston rod vibration in traditional polishing, and reduces manual intervention through automated loading and unloading, avoiding workpiece scratches and accumulation. It achieves a continuous and efficient operation of piston rod polishing from feeding and processing to receiving, improving the overall standardization and practicality of piston rod polishing.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A piston rod polishing auxiliary clamping device, referring to... Figure 1 and Figure 2 The system includes a polishing machine 1 and a support frame 2. Two first rotating seats 3 arranged in a mirror image are fixedly connected to the upper end of the support frame 2. A transmission roller 4 is rotatably connected inside the two first rotating seats 3. Multiple transmission wheels 5 arranged in a linear array are fixedly connected to the outer wall of the transmission roller 4. A motor 6 is fixedly connected to one side of the upper end of the support frame 2. When the transmission roller 4 on the support frame 2 cooperates with the motor 6, the multiple transmission wheels 5 on the outer wall of the transmission roller 4 rotate synchronously, providing stable conveying power to the piston rod and ensuring that the piston rod can move at a uniform speed. Multiple auxiliary wheels 7 arranged in a linear array are fixedly connected to the side of the upper end of the support frame 2 away from the transmission roller 4. The multiple auxiliary wheels 7 on the side of the support frame 2 away from the transmission roller 4 limit the piston rod from the side to prevent it from shifting laterally during movement.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The support frame 2 has four brackets 8 arranged in a linear array fixedly connected to its upper end. Each of the four brackets 8 has two mirror-distributed sliding rods 9 slidably mounted inside its upper end. Multiple sliding rods 9 are paired and fixedly connected to one end of each bracket 8 to a second rotating seat 10. Each of the four second rotating seats 10 has a pressure roller 11 rotatably connected inside it. Each of the four brackets 8 has two mirror-distributed springs 12 fixedly connected to its upper end. Multiple springs 12 are paired and fixedly connected to a fixing plate 13 at their upper ends. The support frame 2 passes through the polishing machine 1. The pressure rollers 11 on the four brackets 8 form an elastic pressure structure with the springs 12 through the sliding rods 9. The elastic force of the springs 12 can... The pressure roller 11 is kept in constant contact with the piston rod surface, providing sufficient clamping force to prevent resonance vibration of the piston rod during polishing. It also automatically adjusts the clamping force according to the diameter of the piston rod, avoiding damage to the piston rod caused by rigid clamping. When the piston rod moves and is polished in the polishing machine 1, the lateral limiting of the auxiliary wheel 7 and the elastic clamping of the pressure roller 11 work together to stably constrain the piston rod from multiple directions, suppressing resonance vibration that may occur during the rotation and movement of the piston rod. This allows the piston rod to maintain a stable posture and uniform movement when passing through the polishing machine 1, thereby making the polishing effect of the polishing wheel on the piston rod more uniform and improving the polishing accuracy of the piston rod.

[0027] Example 2: A piston rod polishing auxiliary clamping device, referring to... Figure 1A feeding device 14 is fixedly installed on one side of the support frame 2, and a receiving device 15 is fixedly installed on the other side of the support frame 2 away from the feeding device 14. By fixing the feeding device 14 on one side of the support frame 2 and the receiving device 15 on the other side away from the feeding device 14, a complete process from workpiece loading to collection after processing is formed, reducing manual intervention and improving overall processing efficiency. During operation, the piston rod to be polished can be placed in the feeding device 14 first, and the feeding device 14 will orderly convey the piston rods one by one to the transmission wheel 5 of the support frame 2, ensuring that the piston rods can be polished. The piston rod then proceeds smoothly to the subsequent clamping and polishing stages. After polishing is completed in the polishing machine 1, it is moved out from the other end of the support frame 2 by the transmission wheel 5. At this time, the receiving device 15 can promptly receive the polished piston rod, preventing the finished piston rod from being randomly piled up, which could cause surface scratches or chaos. Throughout the process, the feeding device 14 and the receiving device 15 respectively undertake the auxiliary work of feeding and receiving, making the polishing process of the piston rod a continuous operation, ensuring the accuracy of feeding and the orderliness of receiving, and further improving the efficiency and standardization of the overall polishing process.

[0028] Reference Figure 1 , Figure 2 and Figure 4The feeding device 14 includes a feeding rack 1401. Multiple first baffles 1402 arranged in a linear array are fixedly connected to one side of the upper end of the feeding rack 1401. Four first mounting plates 1403 arranged in a linear array are fixedly connected to the bottom end of one side of the feeding rack 1401. First mounting seats 1404 are fixedly connected to one side of each of the four first mounting plates 1403. First pneumatic push rods 1405 are fixedly connected inside each of the four first mounting seats 1404. A first lifting frame 1406 is fixedly connected to the telescopic ends of the four first pneumatic push rods 1405. A second baffle 1407 is fixedly connected to one side of the upper end of the first lifting frame 1406. Orderly feeding is achieved through the structure of the feeding rack 1401, first baffles 1402, first pneumatic push rods 1405, first lifting frame 1406, and second baffle 1407. The feeding rack 1401 provides a space for the piston rod to be polished. Multiple baffles 1402 arranged in a linear array are fixedly connected to one side of the feeding rack 1401. The first baffle 1402 can separate the piston rods, preventing them from squeezing and colliding with each other on the feed rack 1401. The first mounting plate 1403 and the first fixed seat 1404 at the bottom of one side of the feed rack 1401 provide a stable mounting base for the first pneumatic push rod 1405. During operation, the first pneumatic push rod 1405 extends and retracts, driving the first lifting frame 1406 to move up and down. When the first lifting frame 1406 rises, the upper side of the lifting frame will lift the piston rods on the feed rack 1401 upwards, so that the bottommost piston rod can smoothly detach from the feed rack 1401 and enter the transmission wheel 5 of the support frame 2. The feeding device 14 can transport the piston rods one by one to the processing area, ensuring that each piston rod can accurately enter the clamping and polishing stage, reducing the tediousness of manual feeding, improving the stability and efficiency of feeding, and providing an orderly material supply guarantee for subsequent polishing processing.

[0029] Reference Figure 1 and Figure 5The receiving device 15 includes a receiving rack 1501. Four second mounting plates 1502 arranged in a linear array are fixedly connected to one side of the bottom of the receiving rack 1501. A second fixing seat 1503 is fixedly connected to one side of each of the four second mounting plates 1502. A second pneumatic push rod 1504 is fixedly connected inside each of the four second fixing seats 1503. A second lifting frame 1505 is fixedly connected to the telescopic ends of each of the four second pneumatic push rods 1504. Four second lifting frames arranged in a linear array are fixedly connected to one side of the upper end of the second lifting frame 1505. A third baffle 1506 is arranged in a linear array. Four fourth baffles 1507 arranged in a linear array are fixedly connected to the upper end of the second lifting frame 1505, away from the third baffle 1506. Three top blocks 1508 arranged in a linear array are fixedly connected to the upper end of the receiving frame 1501. The structure consisting of the receiving frame 1501, the second pneumatic push rod 1504, the second lifting frame 1505, the third baffle 1506, the fourth baffle 1507, and the top blocks 1508 enables the effective handling of the polished piston rod. The receiving rack 1501 provides storage space for the finished piston rods. The second mounting plate 1502 and the second fixed seat 1503 at its bottom provide stable mounting support for the second pneumatic push rod 1504. During operation, when the polished piston rod is transported to the receiving device 15, the second pneumatic push rod 1504 extends and retracts, driving the second lifting frame 1505 to move up and down. When the second lifting frame 1505 rises, the third baffle 1506 on it lifts the polished piston rod and rolls it to the side of the fourth baffle 1507. Then the second pneumatic push rod 1504 retracts, and the top block 1508 guides the piston rod, allowing it to enter the receiving rack 1501 accurately and smoothly. Through this cooperation, the receiving device 15 can collect the polished piston rods in an orderly and neat manner, preventing surface damage or chaos caused by random stacking of piston rods, ensuring the integrity of the finished product, reducing the amount of manual sorting work, and further improving the efficiency and standardization of the entire processing flow.

[0030] Reference Figure 1 and Figure 2The output end of motor 6 is fixedly connected to transmission roller 4 via a coupling, enabling motor 6 to stably transmit power to transmission roller 4. After motor 6 starts, the rotational motion of its output end is precisely transmitted to transmission roller 4 through the coupling, driving transmission roller 4 and transmission wheel 5 on the outer wall to rotate synchronously, thereby providing continuous and stable power for the conveying of piston rod, ensuring that piston rod can move smoothly at a preset speed, thus ensuring the uniformity of piston rod movement during polishing, and providing reliable power guarantee for improving polishing accuracy. Multiple auxiliary wheels 7 are all inclined, which can effectively limit the movement of piston rod from the side. When piston rod is driven by transmission wheel 5 and moves forward through inclined auxiliary wheels 7, it ensures that piston rod always moves smoothly along the preset path, thereby ensuring the stability of the polishing process and helping to further improve the uniformity of polishing.

[0031] Reference Figure 1 , Figure 4 and Figure 5 The upper end of the feed rack 1401 is inclined. The piston rods placed on the feed rack 1401 will naturally slide downwards under their own gravity, achieving initial alignment without an additional power source. When the lower piston rods are conveyed to the processing area, the upper piston rods will automatically replenish them under gravity. Combined with the separating effect of the first baffle 1402, this ensures the piston rods remain orderly arranged, preventing accumulation or jamming, reducing the need for manual intervention, and ensuring that the feed device 14 can continuously and stably provide piston rods to be polished for subsequent processing stages, improving overall feeding efficiency. The upper end of the take-up rack 1501 is also inclined. The upper end of 1501 is inclined, which allows the piston rod to be automatically moved and returned to its position by gravity. After the piston rod is transported from the support frame 2 to the receiving rack 1501, it will slide naturally downward along the inclined direction of the receiving rack 1501. With the limiting effect of the third baffle 1506 and the fourth baffle 1507, the piston rod can be prevented from shifting or piling up on the receiving rack 1501. This allows the finished piston rods to be arranged in an orderly manner in the receiving rack 1501 without the need for manual sorting and placement. It also prevents surface scratches that may be caused by disorderly stacking of piston rods, and ensures that the receiving process is smooth and unobstructed. This provides convenience for the centralized transfer of finished products and further improves the continuity and efficiency of the entire polishing process.

[0032] The implementation principle of this application embodiment is as follows: During operation, the piston rods to be polished are first placed in batches on the feeding rack 1401 of the feeding device 14. Because the upper end of the feeding rack 1401 is inclined, the piston rods naturally slide and converge to the lower position under their own gravity. The first baffle 1402 on the feeding rack 1401 separates the piston rods to prevent them from squeezing and colliding with each other. Then, the first pneumatic push rod 1405 is started, driving the first lifting frame 1406 to move up and down. When the first lifting frame 1406 rises, the second baffle 1407 on it lifts the bottom piston rod of the feeding rack 1401 upward, so that it is separated from the feeding rack 1401 and accurately delivered to the transmission wheel 5 of the support frame 2, realizing orderly feeding. Then, the motor 6 is started, and its output end transmits the rotational power to the transmission roller 4 through the coupling, driving the multiple transmission wheels 5 on the outer wall of the transmission roller 4 to rotate synchronously, thereby driving the piston rod to move at a constant speed along the preset path towards the polishing machine 1. During this process, the auxiliary wheel 7, which is inclined on the support frame 2, contacts the piston rod surface from the side, forming a stable lateral support to prevent the piston rod from shifting laterally. At the same time, the pressure rollers 11 on the four supports 8, under the elastic force of the spring 12, always keep in contact with the piston rod surface through the sliding of the slide bar 9, forming elastic pressure. This can not only prevent the piston rod from shaking due to resonance during polishing, but also automatically adjust the pressure according to the diameter of the piston rod to prevent rigid clamping from damaging the workpiece. When the piston rod enters the polishing machine 1 through the transmission wheel 5, under the combined action of the uniform speed conveying of the transmission wheel 5, the lateral limiting of the auxiliary wheel 7, and the elastic pressure of the pressure rollers 11, the piston rod always maintains a stable posture, ensuring that the polishing wheel polishes it evenly. After polishing, the piston rod continues to be conveyed by the transmission wheel 5 to the receiving device 15 on the other side of the support frame 2. At this time, the second pneumatic push rod 1504 of the receiving device 15 is activated, driving the second lifting frame 1505 to rise. The third baffle 1506 on it lifts the piston rod and guides it to the side of the fourth baffle 1507. Then the second pneumatic push rod 1504 is retracted, and the top block 1508 on the receiving frame 1501 guides the piston rod smoothly into the receiving frame 1501. Because the upper end of the receiving frame 1501 is inclined, the piston rod slides and converges to a lower position under the action of gravity. The third baffle 1506 and the fourth baffle 1507 limit it to avoid disorderly accumulation or surface scratches, thus completing the fully automated operation of the piston rod from feeding, clamping and polishing to receiving.
