In the description of the embodiment, the operator is used as a reference, and the direction close to the operator is a proximal end, and the direction away from the operator is a distal end.

As shown in fig. 1 to 11, the utility model discloses a bolt assembly collection divides material push in mechanism, including support 4, push in the mechanism body set up in on the support 4, push in the mechanism body from last to having set gradually cylinder 1, runner 2 and pressure head 3 of impressing down, runner 2 with the inside cavity of pressure head 3, the depression bar 101 of cylinder 1 of impressing runs through runner 2 with pressure head 3 can follow the tip of pressure head 3 stretches out, runner 2 is rotatable and its inside equipartition has a set of through-hole 201 that is used for loading bolt 9, runner 2 is connected with feeding mechanism 8, bolt 9 certainly feeding mechanism 8 falls into one by one in the through-hole 201, and certainly through-hole 201 falls into in the pressure head 3, by in the frock is impressed to depression bar 101.

As shown in fig. 1, 5, 6, 8 and 10, the feeding mechanism 8 includes a vibration plate 801 and a feeding rail 802 connected to the vibration plate 801, and the bolt 9 is fed from the vibration plate 801 to the feeding rail 802 and moves forward along the feeding rail 802. As shown in fig. 5 to 7, a dropping pipe 803 is provided at the other end of the feeding rail 802, a lower port of the dropping pipe 803 is communicated with the through hole 201, and the bolt 9 drops from the dropping pipe 803 into the through hole 201.

Specifically, a first air cylinder 804 and a second air cylinder 805 are arranged at one end of the feeding rail 802 close to the dropping pipe 803, and the second air cylinder 805 is closer to the pipe orifice of the dropping pipe 803. As shown in fig. 5 to 11, the first cylinder 804 is vertically disposed below the feeding rail 802, and the upward jacking of the cylinder head of the first cylinder 804 causes the bolt 9 to tightly fit with the feeding rail 802 to block the advance of the bolt 9; when the head of the first cylinder 804 is retracted downwards, the bolt 9 can continue to move on the feed rail 802. The second cylinder 805 is horizontally and vertically arranged above the feeding track 802, an inclined block 806 is connected to a cylinder head of the second cylinder 805, the front end of the inclined block 806 has an inclined angle of 45 degrees, as shown in fig. 9, the inclined block 806 horizontally extends and retracts, and when the inclined block 806 retracts, the inclined block 806 overlaps the feeding track 802 to block the bolt 9 from advancing; when the sloping block 806 extends forward, it does not hinder the advance of the bolt 9. The 45 ° angled slope of the ramp 806 faces the side of the drop tube 803 so that the ramp 806 can quickly cut between the bolts 9 and can push the bolts 9 to quickly drop into the drop tube 803.

The first cylinder 804 and the second cylinder 805 cooperate such that only one of the bolts 9 falls into the through hole 201 at a time. The specific working principle is as follows:

first, in the initial state, the cylinder head of the second cylinder 805 ejects the swash block 806 forward, and the swash block 806 overlaps the feed rail 802, hindering the bolt 9 from dropping into the drop duct 803.

Next, the bolt 9 moves forward along the feeding track 802 until stopped from moving forward by the block 806.

Then, the head of the first cylinder 804 lifts the bolt 9 upward. As shown in fig. 6, since there is a gap between the head of the first cylinder 804 and the head of the second cylinder 805, and the gap can accommodate one bolt 9, the second bolt 9 is jacked up by the head of the first cylinder 804 from the direction from the sloping block 806 to the vibrating plate 801, and is tightly fitted with the feeding rail 802, so that the bolt cannot move.

Finally, the cylinder head of the second cylinder 805 is rapidly extended and contracted, the inclined block 806 moves backwards without overlapping the feeding track 802, so that the first bolt 9 blocked by the inclined block moves forwards, and the inclined block 806 is rapidly inserted between the first bolt 9 and the second bolt 9, so that the first bolt 9 rapidly drops into the dropping pipeline 803, and only one bolt 9 is arranged in one through hole 201.

The mutual matching of the first cylinder 804 and the second cylinder 805 ensures that only one bolt 9 falls into one through hole 201 at each time, and also ensures that only one bolt 9 falls downwards in the through hole 201 at each time, so that the smoothness of a falling channel of the whole bolt 9 is ensured, the blockage caused by the fact that a plurality of bolts 9 fall into the through hole at one time is avoided, and the success rate and the smoothness of the pressing of the bolt 9 are ensured.

As shown in fig. 3, the rotary wheel 2 is in transmission connection with a driving motor 202 through a gear and a timing belt 204 and is driven to rotate by the driving motor. Specifically, the driving motor 202 is disposed on one side of the pressing cylinder 1 in order to simplify the apparatus structure. The bottom of driving motor 202 is provided with driving gear 205, the top of runner 2 is provided with driven gear 203, driving gear 205 with pass through between the driven gear 203 hold-in range 204 is connected, driving motor 202 drives driving gear 205 rotates, driving gear 205 passes through hold-in range 204 drives driven gear 203 rotates, driven gear 203 drives runner 2 synchronous revolution.

In order to use the bolt 9 in the runner 2, a channel 301 for dropping the bolt is arranged in the pressure head 3, the channel 301 is communicated with the through hole 201 and a pressure nozzle 302 of the pressure head 3, the pressure nozzle 302 is coaxial with the pressure rod 101, and the bolt 9 can drop to the pressure nozzle 302 from between the through hole 201 and then is pressed into a corresponding tool by the pressure rod 101.

As shown in fig. 4, in order to improve the versatility of the runner 2 for storing the bolts 9, the through holes 201 are uniformly distributed on the runner 2 in an annular shape, and the runner 2 of the present invention can be replaced quickly and has the through holes 201 with different diameters to adapt to the bolts 9 with different specifications. In an actual operation of one-time material taking, in order to prevent the bolts 9 from falling into the channel 301 when the runner 2 collects and stores the bolts 9, so that the bolts 9 are accumulated at the pressure nozzle 302 too much, and the pressure rod 101 cannot press down the bolts 9 one by one, so that one bolt 9 is not arranged in each through hole 201, when the bolts 9 are stored in the runner 2, the bolts 9 are not arranged in the through holes 201 communicated with the channel 301, so as to ensure that the bolts 9 do not fall into the channel 301 when the bolts 9 are stored.

As shown in fig. 3, in order to prevent the bolt 9 from directly falling out of the pressure nozzle 302, an elastic claw 303 is disposed inside the pressure nozzle 302, and after the bolt 9 falls into the pressure nozzle 302, the bolt is blocked by the elastic claw 303 and cannot fall off, and when the bolt 9 is pressed downward by the pressing rod 101, due to the elasticity of the elastic claw 303, the bolt 9 can pass through the elastic claw 303 and be pressed into a tool by the pressing rod 101.

In order to increase the sealing performance between the pressure nozzle 302 and a tool to be pressed in, a sealing ring 304 is arranged on the periphery of the pressure nozzle 302.
