's.
The reciprocating apparatus includes connector sleeve 3, input eccentric shaft 31, exports eccentric shaft 32, front casing 33 and rear casing 34,
The input eccentric shaft 31 is connect with driving device, and the output eccentric shaft 32 is connect with mill handle, and the front casing 33 is socketed in
On support rod 2, two bearings 341 are embedded in the rear casing 34, the input eccentric shaft 31 is fed through two bearings
341, to achieve the purpose that be connected and fixed with rear casing 34.
The front casing 33 and the connection of rear casing 34 form a cavity body, and the connector sleeve 3 is located in the cavity body, in institute
The inside for stating front casing 33 is equipped with the connecting rod 41 to extend back, and the elongated end of connecting rod 41, which is worn, is connected to rear casing 34
Corresponding position on, the lateral wall of the rear casing 34 is equipped with non-slip groove 35, and one end of the connector sleeve 3 is threaded through connecting rod 41
On, a drive rod 42,31 Dan Xuan of input eccentric shaft are equipped on the input eccentric shaft 31 and output eccentric shaft 32
Turn connection on the drive means, the drive rod 42 on input terminal eccentric shaft 31 protrudes into strip-shaped hole 43, the one of the strip-shaped hole 43
Side is equipped with one section of groove 431, and the drive rod 42 on the output eccentric shaft 32 protrudes into groove 431, and input terminal eccentric shaft 31 is made
Unidirectional rotary motion drives connector sleeve 3 to do crankmotion, and is converted into the crankmotion of output end, thus through defeated
Eccentric shaft 32 makees reciprocating rotary rotation with rotary bistrique 1 out.
It is set for the eccentric between the output eccentric shaft 32 and input eccentric shaft 31, exports the drive rod 42 on eccentric shaft 32
Eccentricity be greater than input eccentric shaft 31 on drive rod 42 eccentricity；On the drive rod 42 on the output eccentric shaft 32
Side be equipped with one section of flat mouth section 421.
The application method of the utility model is as follows:
As shown in Fig. 1 to Fig. 4, the mill handle being connected on bistrique 1 is first fed through support rod 2, exposes bistrique 1, limit
Ring 11 is set on mill handle, and the rear end face of the stop collar 11 is abutted with the front end face of support rod 2, to reach axial to bistrique 1 fixed
The purpose of position, then hold on the shell that front casing 33 and the connection of rear casing 34 are formed, non-slip groove 35 can prevent in use process
The case where being slid because taking loosely.
Then, start driving device (not indicating), input eccentric shaft 31 drives eccentric end rotation, inputs on eccentric shaft 31
Drive rod 42 plugs in strip-shaped hole 43, and the drive rod 42 exported on eccentric shaft 32 plugs in groove 431, inputs eccentric shaft 31
It is driven by the driving device, being slidably matched in strip-shaped hole 43 of drive rod 42 of corresponding position is driven, and drive wear simultaneously
It is (i.e. clockwise, inverse shown in a and b state in Fig. 4 that the connector sleeve 3 being located in connecting rod 41 makes the left and right on circumferencial direction
