Description

Technical Field

[0001] This utility model relates to the field of bolt assembly technology, specifically a round head bolt assembly machine. Background Technology

[0002] Bolts are one of the most common fasteners, consisting of a head and a threaded shank. The shank is cylindrical with external threads for use with a nut. Bolts and nuts are used together to connect and secure two parts with through holes. A round-head bolt is a type of bolt with a round head.

[0003] Normally, bolts and nuts are shipped separately after assembly. However, in some special industries such as power transmission towers, highway guardrails, and circuit breakers, bolts and nuts are often used together. Therefore, bolts and nuts are usually shipped together after assembly. Currently, most nuts are tightened manually, which is inefficient. It is also difficult to match bolts and nuts, and manual rotation is inefficient. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] See also Figure 1-5This utility model discloses a round head bolt assembly machine, including a machine base 1. A turntable 2 is rotatably connected to the top of the machine base 1. The top of the turntable 2 has evenly distributed, annularly distributed placement grooves 3 for placing nuts. A through hole 5 that mates with the placement grooves 3 is provided on the top of the machine base 1. A mounting block 6 is fixedly provided on one side of the through hole 5 at the bottom of the machine base 1. A torsion spring 7 is mounted on the mounting block 6. The torsion spring 7 is connected to a baffle 8 that blocks the bottom end of the through hole 5. An electromagnet 9 is also provided on the side of the through hole 5 at the bottom of the machine base 1. An electromagnet 9 is fixedly connected to one side of the baffle 8. The machine base 1 is equipped with an iron plate 10 that works with an electromagnet 9. The machine base 1 is equipped with a tightening gun 17 that works with a placement slot 3. The bottom of the machine base 1 is equipped with a first motor 11 that drives the turntable 2 to rotate. This round head bolt assembly machine initially connects the round head bolt and nut together and places the nut in the placement slot 3. The tightening gun 17 tightens the round head bolt and nut. After the tightened round head bolt and nut are transferred from the tightening gun 17 as the turntable 2 rotates, the electromagnet 9 can be de-energized and the round head bolt can be pressed down so that the tightened round head bolt and nut can be squeezed out of the through hole 5 by the baffle 8.

[0020] A controller is installed on the top of the machine base 1, and the controller is electrically connected to the first motor 11 and the electromagnet 9.

[0021] The turntable 2 is driven to rotate at a fixed angle. The through hole 5 and the placement groove 3 are both hexagonal grooves that match the shape of the nut. Correspondingly, there are six placement grooves and six or more through holes 5.

[0022] The round-head bolt and nut are initially connected together, with the nut placed in the placement groove 3. When the initially connected round-head bolt and nut are rotated to the tightening gun 17, the tightening gun 17 descends and tightens the round-head bolt and nut. After the round-head bolt and nut are tightened, as the turntable 2 rotates, the electromagnet 9 of the tightening gun 17 is de-energized, and the tightened round-head bolt and nut are pressed down, which causes the bolt and thread to squeeze the baffle 8, causing the baffle 8 to rotate downward so that the through hole 5 is opened. At this time, the tightened round-head bolt and nut can be discharged from the through hole 5.

[0023] Specifically, a vertical plate 12 is fixedly connected to one side of the top of the machine base 1, a fixed plate 13 is fixedly connected to the top of the vertical plate 12, a lead screw 14 is rotatably connected to the bottom of the fixed plate 13 and rotatably connected to the top of the machine base 1, a lifting plate 15 is threaded onto the surface of the lead screw 14, a mounting plate 16 is fixedly connected to one end of the lifting plate 15, and a tightening gun 17 is mounted on the mounting plate 16.

[0024] A second motor 18 is mounted on the top of the fixed plate 13 to drive the lead screw 14 to rotate.

[0025] In this embodiment, the second motor 18 drives the lead screw 14 to rotate, which enables the lifting plate 15 to rise and fall, so that the tightening gun 17 can be driven to rise and fall.

[0026] Specifically, a reinforcing plate that is fixedly connected to the bottom of the mounting plate 16 is fixedly connected to the lifting plate 15.

[0027] In this embodiment, the reinforcing plate is triangular in shape.

[0028] Specifically, a linear guide rail 19 is installed on the upright plate 12, and a slider that is slidably connected to the linear guide rail 19 is fixedly connected to the lifting plate 15.

[0029] In this embodiment, the linear guide rail 19 and the slider work together to guide the lifting of the lifting plate 15.

[0030] Specifically, a collection box 4 is provided at the bottom of the machine 1.

[0031] In this embodiment, the collection box 4 can be used to collect tightened round-headed bolts and nuts.

[0032] In summary, this round head bolt assembly machine initially connects the round head bolt and nut together, places the nut in the placement groove 3, and tightens the round head bolt and nut with the tightening gun 17. After the tightened round head bolt and nut are transferred from the tightening gun 17 as the turntable 2 rotates, the electromagnet 9 can be de-energized, and the round head bolt can be pressed down so that the tightened round head bolt and nut are squeezed out of the through hole 5 by the baffle 8.
