Description

Technical Field

[0001] This utility model relates to the technical field of oil seal processing equipment, specifically a multi-station oil seal trimming machine. Background Technology

[0002] Oil seal trimming primarily targets critical areas such as the oil seal lip and outer diameter. By removing burrs, flash, or excess material, the edges are made smooth and flat, ensuring a proper fit between the sealing lip and the journal and preventing leakage. Its core objectives include: improving sealing performance; eliminating burrs prevents scratching the journal and reduces the risk of leakage; extending service life; and improving precision to meet design tolerances and ensure a perfect match between the oil seal and the journal.

[0003] Utility model patent CN219275373U discloses an oil seal production trimming machine. This machine uses a stepper motor to drive a moving screw, which in turn moves a mounting block and a rotary motor via a connecting block. This allows the trimming disc to be positioned according to the size of the oil seal, enabling trimming operations on oil seals of different specifications. By placing the oil seal outside a positioning block, an electric telescopic rod drives a push block to rise, which in turn moves a guide rod that moves the positioning block. This adjusts the distance between the positioning block and the positioning cover, ensuring the positioning block fits against the inner wall of the oil seal, thus facilitating the fixing of oil seals of different specifications. This oil seal production trimming machine not only fixes oil seals of different specifications but also performs trimming processing on them.

[0004] Because the above-mentioned device can only process a single oil seal during the trimming process, and the feeding and unloading of the oil seals both need to be done manually, the degree of automation is low, which greatly affects the processing efficiency and makes it impossible to perform batch trimming of oil seals. At the same time, due to the lack of a flipping mechanism for the oil seals, it is impossible to automatically process both sides of the oil seals. After one side is trimmed, manual unloading and loading are required to complete the trimming of the other side, which is quite inconvenient. In order to solve the above problems, a multi-station oil seal trimming machine is proposed. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a multi-station oil seal trimming machine. This oil seal processing equipment is equipped with a rotatable processing table that can hold a number of oil seals. It can drive the oil seals to rotate, allowing them to switch between different stations and achieve automatic feeding. Simultaneously, during oil seal trimming, it can also drive the oil seals to rotate, facilitating efficient trimming. Furthermore, the feeding and unloading mechanism can simultaneously complete the feeding and unloading of oil seals. In summary, this device has a high degree of automation, automatically and synchronously completing the feeding, unloading, and trimming of oil seals. In addition, during the above process, the flipping mechanism can simultaneously flip the oil seals, facilitating trimming of both sides of the oil seals, thereby improving trimming efficiency. This solves the technical problems of low automation, reduced processing efficiency, inability to process oil seals in batches, and the inability to automatically switch the processing surfaces of oil seals, requiring manual switching.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A multi-station oil seal trimming machine includes a frame, a rotating processing table installed in the middle of the frame for mounting the oil seals to be processed (the rotating processing table rotates itself and also drives the oil seals to rotate), two trimming mechanisms (one for cutting off the injection-molded portion in the middle of the oil seal and the other for cutting off the burrs at the bottom of the oil seal), a flipping mechanism located between the two trimming mechanisms for flipping the oil seals, and a feeding and unloading mechanism that simultaneously completes the feeding and unloading of the oil seals, i.e., placing the untrimmed oil seals on the frame. The device assembles and removes the trimmed oil seals. A number of oil seals can be placed on the rotating processing table, which can drive the oil seals to switch between different workstations to achieve automatic feeding. The set feeding and unloading mechanism can simultaneously complete the feeding and unloading of oil seals. In summary, the device has a high degree of automation and can automatically complete the feeding, unloading and trimming of oil seals. In addition, the flipping mechanism can automatically flip the oil seals, making it easier for the trimming mechanism to trim the front and back of the oil seals, thereby improving the trimming efficiency of the oil seals.

[0008] In one possible implementation, the rotary processing table includes a base with a rotating support shaft mounted on its upper surface and a table plate mounted on top of the rotating support shaft. In addition, a first rotary drive motor and an intermittent divider are mounted on the lower side of the base. The first rotary drive motor drives the rotating support shaft to rotate continuously and intermittently through the intermittent divider. Based on the above structure, the first rotary drive motor can drive the rotating support shaft to rotate, thereby driving the table plate to rotate, so that the oil seal placed on it can rotate to switch positions between different workstations.

[0009] In one possible implementation, several oil seal supports are rotatably mounted on the platform, with drive gears fixedly installed at their bottoms. Several transmission gear shafts located directly below the trimming mechanism and the flipping mechanism are mounted on the base, meshing with the drive gears. The transmission gear shafts are connected by a transmission belt. In addition, a second rotary drive motor is also installed on the base to drive the transmission belt. When the second rotary drive motor rotates, it can drive the transmission belt to move, thereby driving the transmission gear shafts to rotate, thus driving the oil seal supports to rotate. Ultimately, this enables the oil seals to rotate during trimming, facilitating the smooth progress of the trimming work.

[0010] In one possible implementation, the flipping mechanism includes a first cylinder lifting frame on which a rotary cylinder is mounted. A gripper frame is mounted at the front end of the rotary cylinder, wherein two symmetrically arranged movable grippers are mounted. In the above structure, the first cylinder lifting frame can drive the movable grippers to move up and down, while the rotary cylinder can drive the movable grippers to rotate. Based on the above scheme, the oil seal can be gripped by the movable grippers, then lifted, flipped, and then lowered to achieve the flipping of the oil seal.

[0011] In one possible implementation, a drive cylinder is mounted on the back of the rotary cylinder, which is connected to the movable gripper via a drive shaft to drive the movable gripper to clamp and open. The drive shaft passes through the rotary cylinder, and the drive cylinder can pull the movable gripper to achieve clamping and opening via the drive shaft.

[0012] In one possible implementation, the unloading mechanism includes a second cylinder lifting frame with a screw slide drive platform mounted on top. An unloading structure is mounted on the top of the lifting frame, which drives the unloading structure to reciprocate along its length. The second cylinder lifting frame can drive the screw slide drive platform to move up and down, and the screw slide drive platform can drive the unloading structure to move, thereby picking up the oil seals to be processed from the conveyor belt and simultaneously placing the processed oil seals onto the feeding conveyor belt.

[0013] In one possible implementation, the unloading structure includes an unloading pneumatic gripper and a discharge pneumatic gripper. The unloading pneumatic gripper is directly connected to the lead screw slide drive table, while the discharge pneumatic gripper is mounted on the lead screw lifting frame, which is connected to the lead screw slide drive table. Based on the above structure, the oil seal can be clamped and removed by the unloading pneumatic gripper, and the oil seal can be placed on the oil seal support by the discharge pneumatic gripper. Furthermore, the lead screw lifting frame can apply downward pressure to the discharge pneumatic gripper to press the oil seal onto the oil seal support.

[0014] In one possible implementation, the trimming mechanism includes an angle adjustment frame on which an outer shell is mounted. A sliding table is installed inside the outer shell, and a trimming head is connected to its bottom end. A servo motor is installed at the end of the outer shell to drive the sliding table to reciprocate. Based on the above structure, the distance between the trimming head and the oil seal can be adjusted, providing the necessary structural foundation for the smooth progress of the trimming work.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] The oil seal processing equipment is equipped with a rotatable processing table that can hold a number of oil seals. It can drive the oil seals to rotate, allowing them to switch between different workstations and realize the function of automatic feeding. This allows the processing operations of different workstations to be carried out synchronously and continuously, saving time.

[0017] Meanwhile, during the trimming of the oil seal, it can also drive the oil seal to rotate, which facilitates the effective trimming work. In addition, the feeding and unloading mechanism can simultaneously complete the feeding and unloading of the oil seal. In summary, the device has a high degree of automation and can automatically complete the feeding, unloading and trimming of the oil seal.

[0018] In addition, the flipping mechanism can automatically flip the oil seal, making it easier for the trimming mechanism to trim the front and back of the oil seal. This process is completed automatically by the flipping mechanism, eliminating the need for workers to manually load and unload the oil seal. This improves the trimming efficiency of the oil seal and significantly reduces the labor intensity of workers. Attached Figure Description

Detailed Implementation

[0027] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0028] like Figure 1 As shown, this embodiment provides a multi-station oil seal trimming machine, including a frame 1, a rotating processing table 2 installed in the middle of the frame 1 for mounting the oil seal to be processed, the rotating processing table 2 rotating itself and driving the oil seal to rotate, a trimming mechanism 3, which is provided in two sets, one set for cutting off the injection-molded part in the middle of the oil seal, and the other set for cutting off the burrs at the bottom of the oil seal, a flipping mechanism 4, which is located between the two sets of trimming mechanisms 3 for flipping the oil seal, and a feeding and unloading mechanism 5, which can simultaneously complete the feeding and unloading of the oil seal, that is, placing the untrimmed oil seal on the machine. The trimmed oil seals are removed, and a number of oil seals can be placed on the rotating processing table 2. It can drive the oil seals to switch between different workstations to achieve automatic feeding, providing the necessary structural foundation for the synchronous work of each workstation. The feeding and unloading mechanism 5 can simultaneously complete the feeding and unloading of oil seals. In summary, the device has a high degree of automation and can automatically complete the feeding, unloading and trimming of oil seals. In addition, the flipping mechanism 4 can automatically flip the oil seals, making it easier for the trimming mechanism 3 to trim the front and back of the oil seals, thereby improving the trimming efficiency of the oil seals.

[0029] Based on the above structure, when the oil seal to be trimmed does not need to be flipped and requires multiple trimming processes, the flipping mechanism 4 can be replaced with a new set of trimming mechanisms 3. In this case, the frame 1 is equipped with three sets of trimming mechanisms 3, which can perform multiple trimming processes on the oil seal to be processed. The above solution can improve the flexibility of the equipment during use.

[0030] like Figure 2As shown, the rotating processing table 2 includes a base 21, on the upper surface of which a rotating support shaft 22 is mounted. A table plate 23 is mounted on the top of the rotating support shaft 22. Furthermore, a first rotation drive motor 24 and an intermittent divider 29 are mounted on the lower side of the base 21. The first rotation drive motor 24 drives the rotating support shaft 22 to rotate continuously and intermittently via the intermittent divider 29. Based on this structure, the first rotation drive motor 24 can drive the rotating support shaft 22 to rotate, thereby driving the table plate 23 to rotate, allowing the oil seals placed on it to rotate and switch positions between different workstations. In addition, several oil seal support platforms 2 are rotatably mounted on the table plate 23. 5. A drive gear is fixedly provided at its bottom. Several transmission gear shafts 26 located directly below the trimming mechanism 3 and the flipping mechanism 4 are installed on the base 21. They mesh with the drive gear, and the transmission gear shafts 26 are connected by a transmission belt 27. In addition, a second rotation drive motor 28 is also installed on the base 21 to drive the transmission belt 27. When the second rotation drive motor 28 rotates, it can drive the transmission belt 27 to move, thereby driving the transmission gear shafts 26 to rotate, so as to drive the oil seal support 25 to rotate. Finally, the oil seal is driven to rotate during the trimming process, which facilitates the smooth progress of the trimming work.

[0031] like Figures 4-5 As shown, the flipping mechanism 4 includes a first cylinder lifting frame 41, on which a rotary cylinder 42 is mounted. A gripper frame 43 is mounted at the front end of the rotary cylinder 42, in which two symmetrically arranged movable grippers 44 are mounted. In the above structure, the first cylinder lifting frame 41 can drive the movable grippers 44 to move up and down, while the rotary cylinder 42 can drive the movable grippers 44 to rotate. Based on the above scheme, the oil seal can be gripped by the movable grippers 44, then lifted, flipped, and then lowered to achieve the flipping of the oil seal. A drive cylinder 45 is mounted on the back of the rotary cylinder 42, which is connected to the movable grippers 44 through a transmission shaft 46 to drive the movable grippers 44 to clamp and open. The transmission shaft 46 passes through the rotary cylinder 42, and the drive cylinder 45 can pull the movable grippers 44 to move through the transmission shaft 46 to achieve clamping and opening.

[0032] like Figure 3As shown, the unloading mechanism 5 includes a second cylinder lifting frame 51, on the top of which is a screw slide drive platform 52, on which an unloading structure is mounted. The lifting frame 51 drives the unloading structure to reciprocate along its length. The second cylinder lifting frame 51 can drive the screw slide drive platform 52 to move up and down, and the screw slide drive platform 52 can drive the unloading structure to move, thereby enabling the grabbing of oil seals to be processed from the conveyor belt and simultaneously placing the processed oil seals onto the feeding conveyor belt. The unloading structure includes an unloading pneumatic gripper 5. 3. The discharge pneumatic gripper 53 is directly connected to the screw slide drive table 52, while the discharge pneumatic gripper 55 is mounted on the screw lifting frame 54, which is also connected to the screw slide drive table 52. Based on the above structure, the oil seal can be clamped and removed by the discharge pneumatic gripper 53, and the oil seal can be placed on the oil seal support 25 by the discharge pneumatic gripper 55. The screw lifting frame 54 can also apply downward pressure to the discharge pneumatic gripper 55 to press the oil seal onto the oil seal support 25.

[0033] like Figure 6 As shown, the trimming mechanism 3 includes an angle adjustment frame 31, on which an outer cylindrical shell 32 is mounted. A sliding table 34 is installed inside the outer cylindrical shell 32, and a trimming head 35 is connected to its bottom end. A servo motor 33 is installed at the end of the outer cylindrical shell 32, which drives the sliding table 34 to reciprocate. Based on the above structure, the distance between the trimming head 35 and the oil seal can be adjusted, providing the necessary structural foundation for the smooth progress of the trimming work.

[0034] The working principle and usage process of this utility model:

[0035] The oil seal processing equipment is equipped with a rotatable processing table 2, which can hold a number of oil seals. It can drive the oil seals to rotate, allowing them to switch between different workstations and realize the function of automatic feeding. At the same time, it can also drive the oil seals to rotate during the trimming process, which facilitates the effective trimming work. The material unloading mechanism 5 can simultaneously complete the material unloading and unloading of oil seals. In summary, the device has a high degree of automation and can automatically complete the material loading, unloading, and trimming of oil seals.

[0036] In addition, the flipping mechanism 4 can automatically flip the oil seal, making it easier for the trimming mechanism 3 to trim the front and back of the oil seal. This process is completed automatically by the flipping mechanism 4, eliminating the need for workers to manually load and unload the oil seal. This improves the trimming efficiency of the oil seal and significantly reduces the labor intensity of workers.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
