As shown in fig. 2, regarding the feeding mechanism, in this embodiment, considering the problems of small side space of the main shaft 30 of the machine of the current purchasing machine 10 and silence in the workshop, the feeding mechanism selects a belt conveyor line with small occupied area and stable conveying, and the feeding station of the feeding mechanism is provided with a vibration tray or a manipulator, if the occupied area of the equipment is not considered, the vibration tray and the manipulator can be used to place the short rod 412 in the stock bin on the belt conveyor line; a pair of guide pieces 43 which are adjustable in relative distance and are used for guiding the short rod 412 are arranged above the conveying mechanism, the distance between the pair of guide pieces 43 is in a horn shape when being positioned at the head end of the conveying direction of the conveying mechanism, and the distance between the pair of guide pieces is matched with the diameter of the short rod 412 when being positioned at the middle end and the tail end of the conveying direction of the conveying mechanism; a stop piece 44 for stopping the short bar 412 at the forefront end in movement is arranged at the tail end of the conveying direction of the conveying mechanism, a sensor 413 is embedded in the stop piece 44, and the sensor 413 is used for detecting whether the short bar 412 is blocked by the stop piece 44 and stopping the movement on the belt conveying line; when the sensor 413 detects that the short bar 412 stopped moving is arranged at the material blocking piece 44, the belt conveyor line stops working; when the sensor 413 detects that the short bar 412 is not detected after the short bar 412 at the stop 44 is taken away by the finger cylinder 46, the belt conveyor line starts to work; when the sensor 413 detects that the stop 44 has the next stub 412 which is stopped, the belt conveyor line is operated again, so that feeding is effected. In this embodiment, considering that the area of the workshop is small, manual feeding is adopted, so that the manual feeding is not needed, in this embodiment, the front end of the guide member 43 is in a horn shape, the section can be fully filled with the short bar 412, and the short bar 412 can be automatically transported forward under the transmission of the lower belt; it should be noted that, during manual discharging, a gap is left between adjacent short bars 412 to ensure that a gap exists between the short bar 412 blocked by the blocking member 44 from moving and the next short bar 412, so that when the finger cylinder 46 clamps the short bar 412 blocked by the blocking member 44 from moving, the short bar 412 does not collide with the next short bar 412; in actual production, the guide body can be arranged for 3-4 hours to manually feed once; the guide piece 43 is fixed through a fixed plate, waist-shaped holes for screws to pass through or screw holes which are arranged at equal intervals and are arranged in a straight line are formed in the fixed plate, the guide piece 43 is any one of steel wires, steel bars and aluminum bars, the relative distance between the guide pieces 43 is adjustable, the short bar feeding device 40 can be suitable for short bars 412 with different diameters, and the range of the heart-moving machine 10 suitable for processed products is wider; meanwhile, the distance between the threaded holes on the fixing plate can be set to be 1 millimeter, so that the distance between the guide pieces 43 can be adjusted according to specific values in a targeted manner, and the fixing plate is efficient and convenient to use.
The original position of the feeder 10 for installing the stub feeding device 40 is used for fixing a device wire slot and a level for placing correction devices, and a feeding cover body is arranged above the feeder; as shown in fig. 2, in this embodiment, the feeding mechanism in the stub feeding device 40 includes two sections of belt conveying lines, which are respectively provided with a first belt conveying line 41 and a second belt conveying line 42, and the first belt conveying line 41 and the second belt conveying line 42 are integrally L-shaped, so that on one hand, since the space for placing the stub feeding device 40 in the currently purchased feeder is small, the installation difficulty of the belt conveying line is relatively high, the original equipment sheet metal needs to be cut (as shown in fig. 1, a hole is formed in the cover body for the second belt conveying line 42 to pass through), the first belt conveying line 41 is arranged between the automatic long-rod feeding device 20 and the feeding cover body, and the length of the belt conveying line can not be limited by the space available by the currently purchased feeder due to the angle setting of the L-shaped can be used for increasing the feeding quantity of the stub, and reducing the feeding times of workers; in addition, only the first belt conveyor line 41 and a very small portion of the second belt conveyor line 42 are exposed, and a horn-shaped guide 43 is provided on the first belt conveyor line 41; the manual feeding station of the first belt conveyor line 41 is on the same side as the station of the operation table of the heart conveyor 10, and is convenient for workers to operate.
As shown in fig. 3, the blocking member 44 is disposed above the feeding mechanism and between the guide member 43 and the finger cylinder 46, and when the finger cylinder 46 is turned horizontally, the short bar 412 blocked from advancing by the blocking member 44 can be gripped. In this embodiment, the guide 43 and the finger cylinder 46 do not interfere with each other, and when the finger cylinder 46 grips the short bar 412, the guide 43 is located in a neutral position of a clamp plate 47 described below.
With respect to the transfer mechanism, the transfer mechanism includes: the overturning mechanism is used for vertically overturning the short bar 412 transported to the designated position on the material conveying mechanism upwards by 90 degrees after clamping, so that the central axis of the overturned short bar 412 is parallel to the central axis of the main shaft 30 of the machine; the transferring mechanism corresponds to a clamping station of the mechanical main shaft 30, and the short bar 412 which is vertically turned upwards by 90 degrees on the turning mechanism is moved from the transferring station to the clamping station of the mechanical main shaft 30 for clamping of the mechanical main shaft 30.
In this embodiment, as shown in fig. 3 and 4, the turnover mechanism includes a rotary cylinder 45 and a finger cylinder 46 fixed on a movable part of the rotary cylinder 45, where the finger cylinder 46 can integrally reciprocate between a horizontal direction and a vertical direction, and in this embodiment, the rotary cylinder 45 is a 90 ° rotary cylinder 45; the clamping plates 47 are respectively mounted on a pair of finger portions of the finger cylinder 46, and the clamping plates 47 correspond to the lower end portions of the short bar 412 when the finger portions are mounted on the conveying mechanism, namely, when the finger cylinder 46 clamps the short bar 412 blocked by the blocking piece 44 on the conveying mechanism, the lower end portions of the short bar 412 are clamped, and the upper ends of the short bar 412 are vacated for clamping by a clamping jaw cylinder described below.
