Abstract
The utility model relates to a grinding and polishing tool. The grinding and polishing tool comprises a tool head and a power connection shaft. The grinding and polishing tool is characterized in that a flexible shaft and an intermediate connection shaft are connected between the power connection shaft and the tool head; the power connection shaft is provided with an elastic chuck; the front end of the intermediate connection shaft is provided with an elastic chuck which is the same as the elastic chuck arranged on the power connection shaft; the rear end of the intermediate connection shaft is provided with a three-jaw chuck; two ends of the flexible shaft are inserted into the elastic chucks of the power connection shaft and the intermediate connection shaft and locked through locking rings respectively; a connecting rod of the tool head is inserted into the three-jaw chuck of the intermediate connection shaft and locked through a compression sleeve and a lock nut sleeve. According to the grinding and polishing tool, the structure is simple, the production is easy and the cost is low due to the fact that the flexible shaft is formed by steel wire ropes, installation, detachment and replacement of the flexible shaft are convenient due to connection of the elastic chucks and locking of the locking rings, use and operation are simple, the technical process of grinding and polishing of the inner wall of a slender bent pipe is simplified, the efficiency and the quality of the grinding and polishing of the inner wall of the slender bent pipe are improved, the cost of the grinding and polishing is reduced, and the reliability and the safety are good.
Description
Technical field
The utility model relates to a kind of machined tool, is specifically related to a kind of sanding and polishing instrument for slender pipeline inwall or the bright and clean processing of surface of internal cavity.
Background technology
The bright and clean processing of slender pipeline inwall or surface of internal cavity, adopts extension bar to complete conventionally.In tool heads, install polishing and polishing that rigidity extension bar completes slender pipeline inwall or surface of internal cavity additional, but for elongated bend pipe or there is the slender pipeline of certain radian, adopt this rigidity extension bar just cannot complete slender pipeline inwall or inner chamber polishing grinding, this just needs a kind of flexible good milling tools that has.
Summary of the invention
The purpose of this utility model is to solve polishing and the polishing problem of above-mentioned elongated bend pipe inwall or surface of internal cavity, provides a kind of simple in structure, easy to manufacture, the sanding and polishing instrument that can bending turn to.
For achieving the above object, sanding and polishing instrument of the present utility model, comprises tool heads and power coupling spindle, it is characterized in that: between described power coupling spindle and tool heads, be connected with flexible shaft and middle coupling spindle; Described power coupling spindle is provided with collet; The front end of described middle coupling spindle is provided with and collet identical on power coupling spindle, and rear end is provided with three-jaw chuck; Insert respectively in the collet of power coupling spindle and middle coupling spindle at the two ends of flexible shaft, is locked by retaining ring, in the middle of the connecting rod of tool heads inserts, in the three-jaw chuck of coupling spindle, is compressed by clamping sleeve.
In order better to realize above-mentioned purpose:
On described three-jaw chuck, being also provided with locking screw mother set moves axially to prevent clamping sleeve.
The utility model is simple in structure, flexible shaft can be made with steel wire rope, make easy expense low, employing collet connects, retaining ring locking, flexible shaft handling are changed convenient and swift, use simple to operate, when use, only need select the flexible shaft of corresponding length to connect according to the length of bend pipe, again power coupling spindle is connected to the sanding and polishing operation that can complete elongated bend pipe inwall on special electric tool, simplify the technological process of elongated bend pipe inwall sanding and polishing, elongated bend pipe inwall sanding and polishing efficiency and quality are improved, reduce the expense of sanding and polishing, reliability and security are good.

Detailed description of the invention
Sanding and polishing instrument of the present utility model, is connected and composed successively by power coupling spindle 1, flexible shaft 2, middle coupling spindle 3 and tool heads 6.Flexible shaft 2 is made by steel wire rope, and two ends compress with sleeve pipe.Power coupling spindle 1 is provided with collet, and the front end of middle coupling spindle 3 is provided with and collet 8 identical on power coupling spindle 1, and rear end is provided with three-jaw chuck 9.Insert respectively in the collet 8 of power coupling spindle 1 and middle coupling spindle 3 at the two ends of flexible shaft 2, is locked by retaining ring 7.In the middle of the connecting rod of tool heads 6 inserts, in the three-jaw chuck 9 of coupling spindle 3, move clamping sleeve 5 to tool heads 6 ends and compress three-jaw chuck 9, for preventing that clamping sleeve 5 from moving axially, tighten locking screw mother set 4, tool heads 6 is locked in three-jaw chuck 9.
When use, according to the length of pipeline of wanting sanding and polishing, select the flexible shaft 2 of appropriate length, insert respectively in the collet 8 of power coupling spindle 1 and middle coupling spindle 3 at two ends, and lock by retaining ring 7.Again the connecting rod of tool heads 6 is inserted in the three-jaw chuck 9 of middle coupling spindle 3, clamping sleeve 5 moves and compresses three-jaw chuck 9 to tool heads 6 ends, tighten locking screw mother set 4, the connecting rod of tool heads 6 is locked on three-jaw chuck 9, finally power coupling spindle 1 is connected with the rotating shaft of motor special.Again tool heads 6 is placed in to the slender pipeline of wanting sanding and polishing, starter motor, power coupling spindle 1 rotates, thereby drives tool heads 6 to work, and completes the sanding and polishing operation of elongated bend pipe inwall.Sanding and polishing efficiency is high, security good, any surface finish is attractive in appearance.
