Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
See fig. 1-7, the utility model discloses a honing tool for finish machining key groove hole both can adorn and use on horizontal honing machine, can adorn again and use on vertical honing machine. The honing tool comprises a honing rod 1, a taper mandrel 2 which is slidably arranged in an inner hole of the honing rod 1 in a penetrating manner, a honing stick 5 and a bottom plate 3, wherein the bottom plate 3 is pushed by the taper mandrel 2 to provide tension force for the honing stick 5, the honing stick 5 is fixed with the bottom plate 3 through a honing cover 4, the honing cover 4 is arc-shaped and is positioned at the outer side of the honing rod 1 of the honing tool, the width of the honing cover 4 is larger than that of a key groove with a key groove inner hole to be honed, the honing stick 5 is fixed on the outer circumferential surface of the honing cover 4, a filling layer 6 covers the rest outer circumferential surface of the honing cover 4, the honing stick 5 does not protrude out of the filling layer 6, and the wear resistance degree of the filling layer 6 is smaller than that of the honing stick 5.
wherein, the filling layer 6 is formed by mixing AB glue, resin powder and abrasive, the resin powder is mainly used as filler, the abrasive makes the filling layer have certain grinding effect, and the AB glue is used for solidifying the resin and the abrasive into a whole. The abrasive material may specifically be silicon carbide, but the filling layer 6 is not limited to the composition disclosed herein, as long as the filling layer 6 satisfies a degree of abrasion resistance less than that of the honing stick 5, so that the filling layer 6 can be more easily worn away than the honing stick 5.
The honing caps 4 on the respective base plates 3 are fitted to each other into a cylindrical body when the honing tool is in the initial state. The honing cover 4 and the bottom plate 3 are provided with pin holes, and the honing cover 4 and the bottom plate 3 are positioned by pins 7 inserted into the pin holes and are welded and fixed after the positioning is finished. Four groove holes communicated with the inner hole of the honing rod 1 are formed in the outer circular surface of the front end of the honing rod 1, the bottom plate 3 is arranged in the groove holes in a sliding mode, four honing strips 5 are arranged on the outer circular surface of the honing cover 4, and the outer circular surface of the filling layer 6 and the outer circular surface of the honing strips 5 are located on the same cylindrical surface. The honing stick 5 is fixed in the first groove 4-1 on the outer circumferential surface of the honing cover 4 by means of glue bonding. Both ends of the bottom plate 3 protrude out of the middle position for fixing the honing cover 4, so that the guidance and the stability are increased. Two ends of the bottom plate 3 are respectively provided with a second groove 3-1, and a spring ring 8 for resetting the honing strip 5 is arranged in the second grooves 3-1.
The taper mandrel 2 is connected with a pushing rod in the honing machine main shaft through a tail hook, when pressure is given by the pushing rod in the honing machine main shaft, the taper mandrel 2 is pushed to move forwards, the taper mandrel 2 presses the honing strip 5 on the inner wall of the hole of the part, at the moment, the honing machine drives the honing tool to do reciprocating rotary motion back and forth or up and down, the allowance on the wall of the hole to be machined is cut off, the fine machining of the hole to be machined is realized, and the inner hole of the part is honed to the standard size.
The mounting process and the working principle of the honing tool are as follows:
Firstly, four arc-shaped honing covers 4 are respectively positioned with four bottom plates 3 by cylindrical pins 7 and then are welded firmly, then a plurality of honing strips 5 are adhered in first grooves 4-1 of the honing covers 4 by special glue, then recessed areas between adjacent honing strips 5 are uniformly mixed by AB glue, resin powder and a small amount of grinding materials and then are coated, after the AB glue is solidified, a honing tool is arranged on a special tool, an outer arc surface is ground to be as large as an inner hole of a part with a key groove, so that the honing cover 4 with the honing strips 5 is in large-area contact with the inner hole of the part when the inner hole of the part is machined, and the honing strips 5 cannot be clamped in the key groove of the inner hole of the part.
the above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
For example, when the honing tool is in an initial state, gaps exist between the honing covers 4 on the base plates 3, and the honing covers are not spliced into a cylinder, so long as the width of the honing cover 4 is ensured to be larger than the width of the key groove of the inner hole with the key groove to be honed, and the honing cover 4 with the honing stick 5 is in large-area contact with the inner hole of the part, the technical problem to be solved by the application can also be realized.
