[0032] The specific embodiments of the reciprocating polisher for clamping fiber oil stone 8 are described in detail below in combination with the drawings.
[0033] As shown in the drawings, Figs. 1-4 The embodiment provides a reciprocating polisher for clamping fiber oil stone 8, which mainly comprises a shell 1, an air inlet component 2, a turbine 4, a swing arm 5, a connecting piece 6, a telescopic spindle 7, a linear motion bearing 9 and a locking collar 10 and other key components.
[0034] The shell 1 is a hollow structure for accommodating and supporting other components. It is mainly composed of an inner shell 13, a rear shell 14 and a front shell 15. The rear shell 14 is at least partially sleeved on the first end of the inner shell 13, and the front shell 15 is at least partially sleeved on the second end of the inner shell 13. This modular design facilitates assembly, disassembly and maintenance.
[0035] The air inlet component 2 is arranged inside the shell 1 and has an air inlet channel 3 for external air source. When the air source is connected, the gas enters the air inlet component 2 through the air inlet channel 3 and drives the turbine 4 to rotate.
[0036] The turbine 4 is arranged at the air outlet position of the air inlet component 2, and the blades thereon are driven to rotate via the air inlet component 2. The rotation of the turbine 4 converts kinetic energy into mechanical energy for driving subsequent reciprocating motion.
[0037] The swing arm 5 is eccentrically connected to the turbine 4 at the first end. When the turbine 4 rotates, the swing arm 5 will make reciprocating swing around the axis of the turbine 4.
[0038] The connecting piece 6 is hingedly connected to the second end of the swing arm 5. In this way, the reciprocating swing of the swing arm 5 will drive the connecting piece 6 to make corresponding reciprocating motion. Since the telescopic spindle 7 is hollow and its first end cannot be directly connected to the second end of the swing arm 5, the connecting piece 6 is designed as an intermediate component to connect the swing arm 5 and the telescopic spindle 7.
[0039] The telescopic spindle 7 is a hollow structure for clamping fiber oil stone 8. It is placed inside the shell 1 and at least partially extends to the outside of the shell 1 to contact the workpiece for polishing. The first end of the telescopic spindle 7 is connected to the second end of the connecting piece 6, so when the connecting piece 6 makes reciprocating motion, the telescopic spindle 7, under the limitation of the linear motion bearing 9, converts the motion of the swing arm 5 into reciprocating telescopic motion, which is convenient for fiber oil stone 8 to polish the component.
[0040] Linear motion bearing 9: The linear motion bearing 9 is sleeved on the telescopic spindle 7 and is attached to the inner wall of the shell 1. It is used to reduce the friction and resistance of the telescopic spindle 7 during reciprocating motion, and to improve the stability and precision of the motion.
[0041] Locking collar 10: The locking collar 10 is sleeved on the second end of the telescopic spindle 7, and is used to lock the fiber oil stone 8 on the telescopic spindle 7. The locking collar 10 is a hollow structure, and the end portion has a step 11 protruding radially inward, which is positioned against the second end of the telescopic spindle 7. The locking collar 10 is provided with a screw hole in the radial direction, and the locking collar 10 is fixed on the telescopic spindle 7 by a screw. At the same time, the second end of the telescopic spindle 7 is provided with an axial slot cut 12, so that the locking collar 10 can fix the fiber oil stone 8 on the telescopic spindle 7.
[0042] In addition, the second end of the front shell 15 is provided with an end cover 16, which positions the linear motion bearing 9 on the front shell 15. The shell 1 also includes a switch member 17, which is provided on the rear shell 14 and is used to turn on or off the external gas source to the air inlet member 2.
[0043] In use, the user first inserts the fiber oil stone 8 into the telescopic spindle 7, and fixes it on the telescopic spindle 7 by the locking collar 10. Then, the gas source is turned on, and the gas drives the turbine 4 to rotate through the air inlet member 2. The rotation of the turbine 4 drives the swing arm 5 to reciprocate, and in turn drives the telescopic spindle 7 to reciprocate through the connecting member 6. In this way, the fiber oil stone 8 can be uniformly and stably polished on the workpiece under the driving of the telescopic spindle 7.
[0044] The second end of the telescopic spindle 7 is provided with a radial screw hole, and the second end of the connecting member 6 is directly connected with the first end of the telescopic spindle 7 by a screw. This connection makes the connection between the telescopic spindle 7 and the connecting member 6 more stable and reliable, and reduces the unstable motion caused by loose connection.
[0045] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
