Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing component processing, and more specifically, to a sealing component trimming machine. Background Art
[0002] Seals are components used to prevent fluids or solid particles from leaking from adjacent mating surfaces of machinery and equipment. They are also used to prevent foreign matter such as dust and moisture from invading the interior of the machine. Seals have a variety of functions, including: sealing lubricating oil or fluids, blocking foreign contaminants, separating different fluids, and maintaining pressure. In hydraulic systems, seals can effectively prevent hydraulic oil leakage, protect the system from dust and dirt, avoid the expensive loss of hydraulic oil, and possible fire and accident risks.
[0003] Polyurethane oil seals are usually used in the sealing parts of various mechanical equipment to prevent liquid or gas leakage. The working principle of the polyurethane oil seal trimming machine is generally to accurately cut or grind the edge of the oil seal through a specific cutting tool or grinder to remove excess material to achieve the required size and shape.
[0004] Most of the existing oil seal trimming machines are vacuum type oil seal trimming machines, which use a vacuum pump to generate negative pressure, which is transmitted to the vacuum suction cup through a vacuum pipe. Due to the effect of the pressure difference, the oil seal is firmly adsorbed. When the oil seal is cut after injection molding, the oil seal is in a flat cube or cylinder state because it has not yet been formed. The oil seal can be firmly adsorbed due to the negative pressure generated by the vacuum pump. However, when the oil seal is cut and polished in a circular ring state after being cut, the suction nozzle cannot adsorb the oil seal, and the oil seal can only be placed in a groove and limited by the groove. As a result, the oil seal often flies out of the groove after cutting due to the rapid deceleration of the motor, and manual work is required to leave the work station to pick it up, which reduces the work efficiency of oil seal trimming.
[0005] Therefore, in order to solve the above technical problems, the present application proposes a seal trimming machine. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model aims to provide a sealing component trimming machine.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the sealing trimming machine includes a workbench and an L-shaped member;
[0008] The anti-flying mechanism is arranged below the L-shaped piece and is used to prevent the oil seal from flying out of the workbench;
[0009] A quick-release mechanism, arranged above the workbench, is used to remove the anti-fly mechanism;
[0010] The anti-flying mechanism includes a sleeve which is hollow inside and has openings at both ends. Two groups of sliding grooves are symmetrically provided in the sleeve. A moving rod is slidably connected in the sleeve. Two groups of sliding blocks are symmetrically connected to the outer surface of the moving rod. One side of the two groups of sliding blocks is connected to multiple groups of pulleys. The sliding blocks slide in the sliding grooves. A first spring is provided in the sleeve above the moving rod. The moving rod is provided to prevent the annular oil seal from flying out of the workbench. The first spring and the pulley facilitate the up and down movement of the moving rod.
[0011] Preferably, one side of the L-shaped part is connected to a threaded column, one end of the inner wall of the sleeve is provided with a threaded groove, and the outer surface of the threaded column is threadedly connected to the threaded groove. After the first spring has been used for a long time, the sleeve can be removed and the first spring inside can be replaced.
[0012] Preferably, a plurality of handles are symmetrically connected to the outer surface of the moving rod, so that the handles can be lifted manually to drive the moving rod to move upward.
[0013] Preferably, the quick-release mechanism includes a positioning piece, the top of the workbench is connected to an internally hollow shell, a slot is provided at the bottom of the shell, the inner wall of the shell is slidably connected to the movable plate, one end of the positioning piece is connected to the pull plate, the other end of the positioning piece passes through the shell and the movable plate, a second spring is sleeved on the outer surface of the positioning piece, one end of the L-shaped piece is connected to a card piece, the card piece is inserted into the slot, a positioning hole is provided on one side of the card piece, and the positioning piece is inserted into the positioning hole, so that the anti-flying mechanism can be removed easily when the trimmer is cutting and the anti-flying mechanism is not needed.
[0014] Preferably, a vacuum trimmer is installed on the top of the workbench, and multiple sets of cutting tools are arranged on the top of the workbench. The vacuum trimmer controls the movement of the multiple sets of cutting tools.
[0015] Preferably, the top of the workbench is connected to the rotating shaft through a mounting piece, a suction cup is provided on the top of the rotating shaft, a groove is opened on the top of the rotating shaft, the motor drives the rotating shaft to rotate at a high speed, and the oil seal is cut and polished by a tool.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. By setting up the anti-flying mechanism and the handle, the handle can be lifted by one hand to drive the sliding block to slide in the sliding groove to compress the first spring, and the oil seal can be placed in the groove by the other hand. After placing it in, the hand lifting the handle is released, and the first spring releases the elastic potential energy to drive the moving rod to move directly above the rotating shaft to prevent the oil seal from flying out, thereby solving the problem that when grinding in a circular ring state, the suction nozzle cannot absorb the oil seal and can only place the oil seal in the groove. Due to the rapid deceleration of the motor, the oil seal often flies out of the groove.
[0018] 2. By setting up a quick-release mechanism, the pull plate can be manually pulled to drive the positioning rod to move upward and compress the second spring. When the positioning rod is disengaged from the positioning hole, the card can be taken out of the card slot, thereby removing the L-shaped part. When the trimmer is cutting, the anti-fly mechanism can be removed when it is not needed.
[0019] 3. By setting the threaded column and the threaded groove, after the first spring has been used for a long time, the sleeve can be removed and the first spring inside can be replaced, thereby accelerating the rebound efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
