(1) Field of the Invention
The present invention relates generally to an upstanding grinding axle, and more particularly to a structure which can provide positioning function to the rotary axle for the convenience of assembly/disassembly for replacement or cleaning during the grinding process, in order to make the assembling/disassembling process more convenient and improve the grinding efficiency.
(2) Description of the Prior Art
Conventional upstanding grinders, as shown in
In response to the difficulty of replacing sand cloth on the grinding axle of the upstanding grinder for woodwork, the present invention improved the conventional structure, and designed this structure to utilize the limited space on the grinding based to install a set of flexible insert rod component, so that when the rotary axle is still, the rod can be inserted into the insert slot of the rotary axle, and the operators can use one wrench to complete the assembly/disassembly of grinding axle, so that the grinding efficiency could be greatly improved.
Therefore, the present invention provides a set of flexible insert rod component in the limited space of the grinder, so that operators can use fingers to position the rotary axle, in order to improve the operating efficiency of the grinding axle.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
Referring to
Because the grinding axle 25 rotates at a high school for grinding and polishing, the sand belt is worn in a high speed, so that it needs to be replaced after a period of time. However, due to the limited space of the working table 21, the operators need to assemble/disassemble the grinding axle within the limited space between the working table 21 and grinding base 22. The present invention installs a flexible insert rod component 30 on one side of the grinding base 22, and allow the end of the insert rod 41 to be inserted into the insert slot on the rotary axle 23, so that the rotary axle 23 can remain stationary, and operators only need to use one tool to rotate the hexagonal section 26 under the grinding axle 25 to assemble/disassemble the grinding axle 25 quickly.
The structure of the flexible insert rod component 30, as shown in
Therefore, the flexible insert rod component provided by the present invention on the grinding base of the woodworking machine can allow operators to assemble/disassemble the grinding axle conveniently, so that grinding efficiency could be greatly improved.
Claims
1. A type of assembly/disassembly positioning structure of the upstanding grinding axle, which comprising a set of flexible insert rod component installed on one side of the grinding base, so that when pressing the front of the insert rod, its end can be insert into the insert hole on the rotary axle, to limit the rotation of the rotary axle, and after releasing the pressed insert rod, the insert rod can be retracted to the original position.
2. The structure defined in claim 1, wherein said flexible insert rod component can comprise a positioning base, insert rod, spring, limiting slot, and buckling ring.
3. The structure defined in claim 1, wherein said the insert slot can correspond to the insert rod on the rotary axle can be more than one.
