Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring processing fixtures, in particular to a winding shaft sealing ring processing fixture. Background Art

[0002] The winding shaft sealing ring usually refers to the sealing element used in industrial machinery and equipment. Its main function is to prevent the leakage of lubricating oil or liquid from the connection of the shaft. It can also prevent dust, impurities, etc. from entering the bearing or the inside of the mechanical equipment to protect the normal operation of the equipment. This kind of sealing ring is generally installed on the outer cylindrical surface or inner hole of the shaft, and contacts with the shaft or housing to form a seal. When the winding shaft seal is replaced, it needs to be produced with a processing fixture, and the processing fixture is a tooling equipment used to process the winding shaft sealing ring.

[0003] At present, when grinding the sealing ring of the winding shaft, the clamp is particularly important. In the existing technology, the inner wall of the sealing ring is generally propped up by moving the clamping block to limit the position of the sealing ring. After the fixation is completed, the grinding mechanism is cooperated for processing. However, after the sealing ring is ground, it is necessary to take it to the measuring table for measurement. It is inconvenient for the staff to measure it directly on the clamp, and it is difficult to ensure that the sealing ring after grinding meets the use requirements, which is not conducive to the processing of the sealing ring.

[0006] A connection structure, the connection structure is placed on the upper end of the bearing plate;

[0007] A measuring structure, a measuring structure is installed on one side of the connecting structure, and the measuring structure is used to measure the sealing ring. The measuring structure includes a second motor and a mounting frame connected to the output end of the second motor, a forward and reverse screw rod is installed inside the mounting frame, a rotating rod is arranged on the outside of the mounting frame, one end of the rotating rod is connected to the forward and reverse screw rods, a sliding seat is arranged on the outer threaded sleeve of the forward and reverse screw rods, a measuring rod is arranged on the lower end of the sliding seat, scale lines are distributed on the surface of the mounting frame, and the cooperation of the scale lines and the measuring rod can measure the sealing ring, an inner cavity is opened inside the measuring rod, a threaded sleeve is installed inside the inner cavity, a rotating rod is inserted through the surface thread of the measuring rod, and one end of the rotating rod is connected to the cleaning plate.

[0008] By adopting the above technical solution, the sealing ring is fixed by a clamp structure. After grinding, the connecting structure is used to push the measuring structure downward, and then the rotating rod is rotated so that the slide seat drives the measuring rod close to the sealing ring until the inner wall of the measuring rod contacts the outer surface of the sealing ring, and the rotating rod is rotated so that the cleaning plate can be moved out of the inner cavity. When the second motor is started, the mounting frame, the measuring rod and the cleaning plate can be driven to rotate, and the polished sealing ring can be cleaned so that the debris on its surface can be swept away to prevent the debris from affecting the measurement result and reduce the error. Then the position of the measuring rod is fine-tuned by the rotating rod. At this time, the size of the sealing ring can be read by observing the scale line between the two sets of measuring rods.

[0009] Furthermore, the slide seat and the measuring rod are both installed in two groups, and when the two groups of measuring rods move, they can contact the surface of the sealing ring.

[0010] By adopting the above technical solution, when the measuring rod is in contact with the sealing ring, the size of the sealing ring can be read by observing the scale line.

[0011] Furthermore, the clamp structure includes a first motor, which is fixedly mounted on the outer wall of the processing placement table. The output end of the first motor is connected to a screw rod, and the outer thread sleeve of the screw rod is provided with a thread block. The screw rod is a forward and reverse screw rod structure, and a clamping ring is installed on the upper end of the thread block. When the first motor is operating, it can drive the screw rod to rotate, so that the thread block drives the clamping ring to move.

[0012] By adopting the above technical solution, when the four groups of clamping rings move separately, the sealing ring can be propped up and the position of the sealing ring can be restricted.

[0013] Furthermore, a cavity is provided inside the processing and placing table. By adopting the above technical solution, the cavity is used to install the screw rod.

[0014] Furthermore, the connecting structure includes a rotating handle, which is located at the lower end of the bearing plate, and the top of the rotating handle passes through the bearing plate and is connected to the fixed plate. A sliding groove is opened on the side wall of the fixed plate, and a sliding rod is installed inside the sliding groove. A slider is slidingly arranged on the outer side of the sliding rod. When the slider slides, the slider can be connected to the fixed plate by bolts. A T-shaped connecting plate is installed on one side of the slider, and the connecting plate is used to support the second motor.

[0015] By adopting the above technical solution, the fixed plate can be driven to rotate by holding the rotating handle, so that the connecting plate and the measuring structure are moved above the processing placement table, and then the slider is slid to make the connecting plate and the measuring structure move downward to the sealing ring. When the measuring rod is flush with the sealing ring, the slider is fixed with bolts to fix the position of the connecting plate and the measuring structure, which is beneficial for subsequent measurements.

[0016] By implementing the above scheme, the utility model has the following beneficial effects:

[0017] The utility model provides a winding shaft sealing ring processing fixture, which places the sealing ring on a processing placement table and fixes it using a fixture mechanism, which is beneficial to the grinding processing of the sealing ring. After completion, the position of the measuring structure can be adjusted using the connection structure so that it is above the sealing ring, and then the rotating rod is rotated so that the sliding seat drives the measuring rod to approach the sealing ring until the inner wall of the measuring rod contacts the outer surface of the sealing ring, and the rotating rod is rotated so that the cleaning plate can be moved out of the inner cavity. When the second motor is started, the mounting frame, the measuring rod and the cleaning plate can be driven to rotate, and the outer wall of the sealing ring after grinding can be cleaned, so that the debris contaminated on the surface can be swept away to prevent the debris from affecting the measurement result, effectively reducing the error, and then the rotating rod is used to fine-tune the position of the measuring rod. At this time, the size of the sealing ring can be read by observing the scale line between the two sets of measuring rods, and the measurement can be completed. If the size does not match, the measuring structure can be removed and ground again, otherwise the sealing ring can be taken out, which can effectively save time. BRIEF DESCRIPTION OF THE DRAWINGS
