Description

Technical Field

[0001] This utility model belongs to the field of oil seal production technology, and in particular relates to a quick-release oil seal trimming tool and trimming machine. Background Technology

[0002] Oil seals are mechanical components used to seal grease, isolating lubricated parts from power-generating parts in transmission systems and preventing lubricant leakage. After being processed by molds and other equipment, oil seals often have burrs or rubber threads on their outer ring and lip. These burrs can affect the quality and performance of the oil seal, leading to problems such as poor sealing and installation difficulties. Therefore, they must be trimmed to ensure the dimensional accuracy and sealing performance of the oil seal, meeting the requirements of mechanical equipment.

[0003] To improve trimming efficiency, a trimming machine is usually used to trim the rubber wires of the oil seal. Existing trimming machines are usually equipped with a trimming scissor mechanism, which includes trimming scissors, a blade holder, and fixing screws. The trimming scissors are fixed to the blade holder by multiple fixing screws. When replacing the trimming scissors, all the fixing screws need to be removed and then the new trimming scissors need to be installed on the blade holder by multiple fixing screws. Obviously, the existing trimming scissor mechanism has the problems of cumbersome replacement and low disassembly and assembly efficiency. Utility Model Content

[0027] Please see Figure 1 and Figure 2 As shown, in this embodiment, a quick-release oil seal trimmer includes a shank 10, an adjusting part 20, a moving part 30, a fixing sleeve 40, and an elastic element 50. The shank 10 has a receiving cavity 11 for inserting the cutter 100. The receiving cavity 11 has a notch 110 extending in a first direction. The fixing sleeve 40 is detachably and fixedly fitted around the receiving cavity 11 of the shank 10. An elastic element 50 located within the receiving cavity 11 is mounted on the fixing sleeve 40. The moving part 30 is movably installed within the fixing sleeve 40 in the first direction. The first end of the moving part 30 extends out of the notch 110. The top surfaces of both ends are provided with locking ramps 31, which are located below the elastic member 50. The bottom surface of the second end of the moving part 30 presses against the end of the cutter 100 that is inserted into the receiving cavity 11. The first direction is the length direction of the cutter bar 10. The adjusting part 20 is adjustablely mounted on the cutter bar 10 along the first direction. The adjusting part 20 abuts against the first end of the moving part 30. Rotating the adjusting part 20 moves it closer to the cutter 100 along the first direction, so as to drive the locking ramps 31 of the moving part 30 to abut against the elastic member 50. The cutter 100 is pressed and fixed in the receiving cavity 11 by the cooperation of the elastic member 50 and the locking ramps 31.

[0028] As can be seen, through the cooperation of the adjusting part 20, the moving part 30 and the elastic element 50, when the rotating adjusting part 20 moves closer to the tool, the locking inclined surface 31 of the moving part 30 abuts against the elastic element 50. Through the cooperation of the elastic element 50 and the locking inclined surface 31, the tool 100 is pressed and fixed in the receiving cavity 11. When disassembly and assembly are required, the tightness of the tool 100 can be adjusted by simply adjusting the adjusting part 20, which is convenient for subsequent replacement and greatly improves the disassembly and assembly efficiency.

[0029] In one embodiment, the movable part 30 is an "L"-shaped blade holder, which includes a horizontal section 32 and a vertical section 33. The locking slope 31 is formed on the top surface of the first end of the horizontal section 32, and the bottom of the vertical section 33 is integrally formed with the second end of the horizontal section 32. The vertical section 33 is disposed through the notch 110.

[0030] As can be seen, by setting the moving part 30 as an "L"-shaped tool holder with a horizontal section 32 and a vertical section 33, with the vertical section 33 passing through the notch 110, the adjusting part 20 pushes the vertical section 33 to move when locked, thus providing a moving part 30 that is easy to implement and has a simple structure.

[0031] In one embodiment, the adjusting part 20 is an adjusting nut, and the tool bar 10 has an external thread section 21, on which the adjusting nut is installed.

[0032] As can be seen, by setting the adjusting part 20 as an adjusting nut and providing an external thread section 21 on the tool holder 10, rotating the adjusting nut and moving it closer to the moving part 30 in cooperation with the adjusting nut and the external thread section 21, the operation is simple and the disassembly and assembly efficiency is high.

[0033] In one embodiment, the fixing sleeve 40 is a square tool holder, which is detachably mounted on the middle of the tool holder 10 via the disassembly assembly 60.

The shank of the locking screw 61 passes through the first through hole 63 and is locked in the first threaded hole 62, so that the head of the locking screw 61 abuts against the square tool holder to install the square tool holder on the tool bar 10.

[0035] As can be seen, by setting the disassembly and assembly component 60 as a locking screw 61, which passes through the first through hole 63 of the square tool holder and is locked in the first threaded hole 62 in the middle of the tool holder 10, a disassembly and assembly component 60 that is convenient to operate, efficient, and has a stable and reliable connection is provided.

[0036] In one embodiment, the disassembly and assembly assembly 60 includes a plurality of first magnets disposed on the tool holder 10 and a plurality of second magnets disposed on the square tool holder. Each first magnet corresponds to one second magnet. The magnetic poles of the first magnet and the second magnet are opposite. The square tool holder is detachably mounted on the tool holder 10 by the attraction between the first magnet and the second magnet.

[0037] As can be seen, by setting the disassembly assembly 60 to multiple first magnets mounted on the tool holder 10 and multiple second magnets mounted on the square tool holder, the square tool holder is installed on the tool holder 10 by the attraction of the first magnets and the second magnets, providing a disassembly assembly 60 that is quick to assemble and disassemble and easy to maintain.

[0038] Of course, the disassembly and assembly component 60 may also include other types of disassembly and assembly structures, which will not be elaborated on here.

[0039] In one embodiment, the elastic element 50 is a horizontally arranged elastic pin, with both ends of the elastic pin installed on the side wall of the inner hole of the fixing sleeve 40 along its own length direction.

[0040] As can be seen, by designing the elastic element 50 as a horizontally placed elastic pin, with both ends of the elastic pin installed on the side wall of the inner hole of the fixed sleeve 40 along its own length direction, the vertical downward pressing force of the moving part 30 gradually increases as the angle of the inclined plane increases during the sliding of the elastic pin on the locking inclined plane 31, thus providing an elastic element 50 with good pressing effect and simple structure.

[0041] In one embodiment, a connecting component 70 is provided at the end of the tool holder 10, and the tool holder 10 is connected to the execution end of an external robot arm through the connecting component 70.
