Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a cutter for bearing processing, including blade installed part 1, cutter base 2, locking fixture block 3, remove seat 4, compression spring 5, double thread lead screw 6, adjust rocking arm 15, blade 16, the outer wall fixedly connected with driven plate 8 of double thread lead screw 6, the right-hand member face fixedly connected with driven fixture block 14 that a plurality of circumference arrays set up of driven plate 8, the outer wall of double thread lead screw 6 rotates and is connected with driving-disc 10 that is located the driven plate 8 right side, the left end face fixedly connected with of driving-disc 10 and the driving fixture block 12 that a plurality of circumference arrays set up that driven fixture block 14 corresponds, the outer wall cover of double thread lead screw 6 is equipped with spring 13, both ends respectively butt driven plate 8 and driving-disc 10 about spring 13, the outer wall threaded connection of double thread lead screw 6 has sleeve 11, the left end face butt driving-disc 10 of sleeve 11, the outer wall fixed connection of driving-disc 10 adjusts rocking arm 15.

The left end face of the adjusting rotating arm 15 is fixedly connected with a dustproof sleeve 9, the inner wall of the dustproof sleeve 9 is connected with the driven disc 8 in a sliding mode, the right end face of the cutter base 2 is provided with a dustproof groove 7 corresponding to the dustproof sleeve 9, and the inner wall of the dustproof groove 7 is connected with the dustproof sleeve 9 in a sliding mode.

A pair of push plates 17 for rotating the sleeve 11 is fixedly connected to the outer wall of the sleeve 11.

The end surfaces of the plurality of driving dogs 12 and the plurality of driven dogs 14 close to each other are all triangular peaks.

The working principle is as follows: when the adjusting rotating arm 15 needs to be rotated to separate or approach the two locking clamping blocks 3, the sleeve 11 is firstly rotated to move left and push the driving disc 10 to move left, the driving disc 10 moves left until the driving clamping block 12 on the driving disc 10 abuts against the driven disc 8, and each driving clamping block 12 is located between the two driven clamping blocks 14; at this time, the rotating adjusting rotating arm 15 can drive the driving disk 10 to rotate, and the driving disk 10 can drive the driven disk 8 to rotate through the driving clamping block 12 and the driven clamping block 14, so that the double-thread screw 6 is driven to rotate; when the adjusting rotating arm 15 is not used after the disassembly and assembly are finished, the sleeve 11 is rotated by the push plate 17 to move rightwards, the driving disc 10 moves rightwards under the action of the spring 13, the driving fixture block 12 is far away from the driven fixture block 14, and the double-threaded screw rod 6 cannot be rotated by the driven disc 8, the driving disc 10, the driving fixture block 12 and the driven fixture block 14 when the adjusting rotating arm 15 rotates randomly; dust is prevented from entering between the driven disc 8 and the driving disc 10 through the dust-proof groove 7 matched with the dust-proof sleeve 9; by cutting the end surfaces of the driving latch 12 and the driven latch 14 close to each other into triangular peaks, when the driving disc 10 moves left to approach the driven disc 8, the driving latch 12 and the driven latch 14 cannot be abutted.

When the dismouting is accomplished the back and is not used regulation rocking arm 15, rotate sleeve 11 and can make driving-disc 10 move to the right with it under the spring 13 effect, driven fixture block 14 is kept away from to drive fixture block 12, at this moment adjust rocking arm 15 and rotate at will and can't make two screw lead screw 6 rotate, can effectively avoid taking place to rotate easily when using under the influence of collision, vibrations, gravity, make the locking fixture block take place to remove, influence the fixed of blade, the adaptation is safer more stable.

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.
