Description
Technical Field
The utility model relates to a honing tool technical field, especially a honing tool with honing strip anti-drop mechanism.
Background
When the honing tool is arranged on a honing machine for honing, in order to prevent the honing strip from being partially thrown out or falling off due to centrifugal force to cause collision with a workpiece and even prevent parts from being honed, fixing grooves are formed at two ends of a bottom plate of the honing strip of the honing tool, and rubber rings or spring rings for withdrawing the swelled honing strip are arranged on inner hoops of the fixing grooves.
However, the honing strip anti-drop structure adopting the rubber ring or the spring ring has the following disadvantages: the structural space is large, and the honing tool can only be suitable for honing tools with larger volumes; in addition, because the fixing grooves are required to be arranged at the two ends of the honing strip, the structural strength of the honing strip can be influenced; because the bottom plate is provided with the fixed groove hooping the rubber ring or the spring ring, the bottom plate of the honing strip can extend out of the honing cutting layer of the honing strip, and the guiding effect of the sliding groove of the honing rod on the honing strip is weakened.
Therefore, the existing small honing tool matched with the vertical honing machine is not provided with a rubber ring or a spring ring, the honing strip is prevented from falling off only by the self-adsorption action of the honing strip and the taper mandrel, the requirement on the processing precision is high, the self-adsorption action can be reduced or even failed due to abrasion after the honing strip is used for a period of time, and the honing strip still has the risk of falling off by independently relying on the self-adsorption action.

Detailed Description
As shown in fig. 1 to 7, a honing tool having a honing stick anti-drop mechanism includes a honing rod 1 and a honing stick 2 installed in a sliding groove 6 of the honing rod 1, the honing rod 1 has the honing stick anti-drop mechanism, the honing stick anti-drop mechanism includes an anti-drop spring strip 3 and a press fitting member 4, the honing stick 2 has a through groove or through hole 5 extending along a length direction thereof, the anti-drop spring strip 3 passes through the through groove or through hole 5, and both ends of the anti-drop spring strip 3 are press fitted on the honing rod 1 through the press fitting member 4, and top surfaces of the anti-drop spring strip 3 and the press fitting member 4 are lower than a honing cutting surface of the honing stick 2.
The honing stick 2 comprises a honing cutting layer 2-1 and a bottom plate 2-2 below the honing cutting layer 2-1, and a through groove or through hole 5 of the honing stick 2 is positioned on the bottom plate 2-2. In fig. 6, the structure of the honing strip 2 for passing through the anti-dropping spring strip 3 is a through hole 5, and is processed by wire cutting. The through hole 5 is tightly matched with the anti-falling spring strip 3.
The anti-drop spring strip 3 is sheet-shaped.
The pressing part 4 comprises a pressing plate 4-1 and a fixing screw 4-2, the pressing plate 4-1 is fixed on the honing rod 1 through the fixing screw 4-2, and the pressing plate 4-1 is pressed above the end part of the anti-drop spring strip 3. The pressure plate 4-1 is provided with a protruding part, and the pressure plate 4-1 is pressed above the end part of the anti-drop spring strip 3 through the protruding part.
The outer surface of the honing rod 1 is provided with a yielding groove 7, and the anti-falling spring strip 3 and the press fitting piece 4 are arranged in the yielding groove 7 and used for enabling the top surfaces of the anti-falling spring strip 3 and the press fitting piece 4 to be lower than the outer surface of the honing rod 1. The bottom of the section of the abdicating groove 7 corresponding to the pressing piece 4 is closed, and is used for installing the pressing piece 4, and the bottoms of other sections of the abdicating groove 7 are communicated with the inner cavity of the honing rod 1.
The honing tool also comprises a taper mandrel 8, a push rod 9, a connecting pin 10, a pressure spring 11, an upper gasket 12 and a lower gasket 13, wherein the push rod 9 is connected with the taper mandrel 8 through the connecting pin 10, the front end of the taper mandrel 8 acts on the bottom of a bottom plate 2-2 of the honing strip 2 to push the honing strip 2 to rise, and the pressure spring 11 is sleeved on the push rod 9 and acts between the upper gasket 12 and the lower gasket 13 respectively.
