[0034] See also Figure 1 and Figure 2 A fixing fixture for cutting the tail of a bolt includes an equipment frame 1, a first slider 2, a first cylinder 3 and a second cylinder 4.

[0035] The top of the equipment rack 1 is divided into a material receiving area and a fixing area in a horizontal first direction. In order to facilitate the subsequent description in terms of orientation, the first direction is set to correspond to the front-back direction, with the material receiving area in front and the fixing area in the back.

[0036] The material receiving area is provided with a first groove 1a, and the first groove 1a is used to accommodate bolts in a horizontal state, that is, the bolts are in a horizontal state after being transferred to the first groove 1a through the vibration plate.

[0037] Optionally, a suitable track is used for guiding so that the bolts sent out of the vibration plate are gradually turned from a vertical state to a horizontal state, and the movable stopper 1d is cooperated to make the bolts fall into the first groove 1a one by one in a gap manner.

[0038] Optionally, one of the first vertical inner walls of the first groove 1a has an upward extension 1a1 on the side close to the second groove 1b. In this way, the bolts sent out from the vibration plate are in a state of tilting slightly forward along the track with the nut slightly tilted forward, and the bolts hit the extension 1a1, and cooperate with the movable stopper 1d, so that the bolts fall into the first groove 1a one by one with gaps, and after the bolts fall into the first groove 1a, one end of the nut falls forward.

[0039] Furthermore, the other first vertical inner wall of the first groove 1a is inclined at one side close to the second groove 1b, so that it is convenient for the bolt to fall into the first groove 1a at the beginning.

[0040] See also Figure 3 and Figure 5 A second groove 1b is provided in the fixing area, and a horizontal inner wall of the second groove 1b is lower than a horizontal inner wall of the first groove 1a.

[0041] The first sliding block 2 is connected to the second groove 1b in a horizontal sliding manner along a second direction perpendicular to the first direction. Specifically, a linear guide rail may be provided between the two.

[0042] When the first slider 2 is in the inner limit position, a third groove 7 connected to the first groove 1a is formed between the top surface of the first slider 2, the first protrusion 2a on the top surface, and the equipment frame 1. Specifically, a connecting plate 1c is fixedly connected to the equipment frame 1, and a second protrusion 1c1 is provided on the bottom surface of the connecting plate 1c. A third groove 7 is formed between the top surface of the first slider 2, the first protrusion 2a, the connecting plate 1c, and the second protrusion 1c1.

[0043] The first cylinder 3 is disposed on the equipment frame 1 and is used to push the bolt in the first groove 1 a into the third groove 7 .

[0044] In addition, when the first slider 2 is in the inner limit position, a processing station 8 for fixing the bolt is formed between the first outer wall of the first slider 2 and the second groove 1b. Specifically, the equipment frame 1 is provided with a stopper 1d at the rear side of the processing station 8. The first slider 2 and the second groove 1b clamp the threaded part of the bolt, and the stopper 1d is used for the end of the bolt with the nut to resist. In this way, the bolt can be cut by using a rotating disc cutter close to the other end of the bolt.

[0045] Optionally, the fixing fixture for cutting the bolt tail also includes a third cylinder 5. The third cylinder 5 is arranged on the equipment frame 1, corresponding to the processing station 8, and is used to press the bolt in the processing station 8 from top to bottom. Specifically, the third cylinder 5 can be arranged on the above-mentioned connecting plate 1c. In this way, the bolt is limited from jumping upward, so that the bolt is fixed on the processing station 8 more stably.

[0046] Optionally, the fixing fixture for cutting the bolt tail also includes a fourth cylinder 6. The fourth cylinder 6 is arranged on the equipment frame 1, corresponding to the processing station 8, and is used to resist the nut of the bolt in the processing station 8 in the horizontal direction. Accordingly, the above-mentioned stopper 1d is not directly fixed on the equipment frame 1, but is fixed on the piston rod of the fourth cylinder 6. In this way, the stopper 1d can also be resisted by one end of the bolt with the nut, and the position of the stopper 1d can be adjusted to better adapt to bolts of different lengths.

[0047] See also Figure 3 , Figure 4 and Figure 6 The processing station 8 also has a blanking opening 8a.

[0048] Optionally, the blanking port 8a may be located at the front side of the processing station 8. Combined with the setting of the fourth cylinder 6, after the tail cutting is completed, the disc cutter moves forward and away from the bolts on the processing station 8, leaving a sufficient distance, and the fourth cylinder 6 pushes the bolts with the tail cut on the processing station 8 forward.

[0049] Optionally, the blanking port 8a is arranged on the horizontal inner wall of the second groove 1b, and the blanking port 8a is provided with a baffle 8b that can be opened and closed. Specifically, two strip-shaped through grooves 1e can be arranged at the position of the equipment frame 1 corresponding to the second groove 1b, and an optical axis 9 is arranged along the strip-shaped through grooves 1e, and a third protrusion 8b1 penetrating from the strip-shaped through grooves 1e is fixedly arranged at the bottom of the baffle 8b, and the third protrusion 8b1 is fixedly connected to the matching linear bearing on the optical axis 9. An elastic member 10 for closing the baffle 8b is arranged between the baffle 8b and the equipment frame 1. Specifically, the elastic member 10 can be a compression spring, which is sleeved on the optical axis 9. When the first slider 2 is in the state of moving to the outer limit, it can also overcome the elastic member 10 to open the baffle 8b, that is, when the baffle 8b is closed, the top surface of the baffle 8b serves as the horizontal inner wall of the second groove 1b for the bolt to be placed. Specifically, the bottom surface of the first slider 2 is provided with a groove 2b, and the top surface of the baffle 8b is provided with a fourth protrusion 8b2 that enters the groove 2b. When the first slider 2 moves outward to the outer limit position, after the inner wall of the groove 2b abuts against the fourth protrusion 8b2, the first slider 2 can slide with the baffle 8b, so that the blanking port 8a is opened and the bolt falls.

[0050] The second cylinder 4 is disposed on the equipment frame 1 and is used to drive the first sliding block 2 to slide.

[0051] In addition, when the first slider 2 is at the outer limit position, the bolt in the third slot 7 can fall into the second slot 1b. That is, the position of the first slider 2 at the outer limit position needs to be controlled so as not to block the portion of the second slot 1b corresponding to the third slot 7.

[0052] The first slider 2 is first in the inner limit position, and the first cylinder 3 pushes the bolt in the first groove 1a forward, and the bolt leaves the first groove 1a and enters the third groove 7; in the process of the first slider 2 moving outward to the outer limit position, the bolt in the third groove 7 falls into the second groove 1b, and the bolt on the processing station 8 is unloaded from the blanking port 8a; in the process of the first slider 2 moving inward to the inner limit position, the first slider 2 moves to the processing station 8 with the bolt in the second groove 1b to fix the bolt.
