Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: a grinding mechanism for column products comprises two grinding wheels 1 which are symmetrically distributed, wherein a rotating shaft of each grinding wheel 1 is connected with a grinding wheel motor 3 through a belt pulley transmission pair 2, the grinding mechanism further comprises a turntable support 4, a turntable 5 is rotatably supported on the turntable support 4, the turntable 5 is connected with a working shaft of a turntable motor 6, a plurality of workpiece insertion holes 7 which are uniformly distributed in the circumferential direction are formed in the turntable 5,

The utility model discloses column class product abrasive machining mechanism's working process as follows: the column products which need end face grinding treatment are placed in a vibration feeding tray 8, the vibration feeding tray 8, a linear vibration feeding device 9 and a turntable motor 6 are started, under the action of the turntable motor 6, the turntable 5 rotates at a constant speed, the vibration feeding tray 8 conveys the column products to the linear vibration feeding device 9, the linear vibration feeding device 9 conveys the products to a certain workpiece jack 7 on the turntable 5 one by one, and because the positioning reference plate 10 is arranged at the opposite side of the linear vibration feeding device 9, the column products cannot move forward continuously after one end of the products is contacted with the positioning reference plate 10, the products move in place at the moment and then move towards the direction of the grinding wheel 1 under the action of the turntable 5,

in the moving process, a product firstly moves to the grating ruler mechanism 11, some products which are not in contact with the positioning reference plate 10 firstly contact with the guide surfaces 18 which are obliquely distributed, and are pushed towards the positioning reference plate 10 by the adjusting block 17 under the action of the spring 15 until the other end of the products contacts with the positioning reference plate 10, because the distance between the correcting surface 19 and the rotating disc 5 is smaller than the distance of the product protruding from the rotating disc 5 in a standard state (namely, in a state that the product is in contact with the positioning reference plate 10) under the condition that no product exists, the adjusting block 17 drives the adjusting shaft 16 to axially move in the sleeve 14 under the reaction of the product and restore to the initial position under the action of the spring 15 after the product leaves, and the grating ruler detects each displacement of the adjusting shaft 16, the detection result is sent to a control system, the control system compares the displacement detected each time with a standard parameter, so that whether the detected product is a qualified product or a defective product (the defective product is divided into an overlong condition and a too short condition) is judged, once the detected product is found to be the defective product, the control system controls an air pump to work, the defective product is pushed out from a workpiece jack 7 by using air pressure at the next station, and the defective product finally enters a defective product container after entering a recovery pipeline 21;

can be through the qualified product of defective products recovery mechanism 12 can be transported to two emery wheels 1 under the effect of carousel 5 to in getting into the clearance between two emery wheels 1, emery wheel 1 is at the uniform velocity under the effect of emery wheel motor 3 and rotates, outstanding grinding process in two terminal surfaces in carousel 5 of cylindrical product, and cylindrical product has just accomplished the grinding process operation after breaking away from contact with emery wheel 1, and the operator utilizes the instrument to push out and collect it from work piece jack 7 can.
