Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an automatic nail feeding and tightening gun head. Background Art

[0002] In assembly operations, the connection between two parts is often involved, and the connection between the two parts can be a variety of ways such as snap-on, plug-in, and threaded connection. Among them, connecting two parts with screws is a relatively common connection method. In the assembly process of the electronic silicone oil clutch, screws are needed to connect the two parts. The traditional method of manually tightening screws is inefficient. Therefore, automatic screw tightening equipment is often used in the assembly process. The equipment includes a mounting plate, a mounting arm, a vibration plate and a feed pipe. The feed pipe is connected to the mounting arm. The screws blown out by the vibration plate pass through the feed pipe to the mounting arm. The screws are positioned by the clamp in the mounting arm. Then, the gun head on the mounting plate tightens the screws on the product under the action of the driving mechanism. In this type of equipment, the screws are positioned only by the clamp, and the gun head moves directly downward. Because the clamp has poor adaptability to screws of different specifications, it is easy to cause the screws positioned by the clamp to be not vertically set, and there is an angle offset between the screw and the gun head. In this way, the screws will be driven into the product in an inclined state, resulting in unstable connection between product parts and even damage to the threaded structure of product parts.

[0003] A Chinese patent application with application number 201520807783.4 discloses a novel tightening gun gun head assembly, comprising: a gun head body, with a through-channel formed inside, the through-channel forming a through-port at the first end of the gun head body, and the through-channel forming a through-port at the second end of the gun head body; a screw channel, connected to the through-channel; an excitation rod, which is inserted into the through-channel from the through-port; a tightening rod, connected to the excitation rod; and at least two jaws, the jaws comprising a first end for pivoting to the gun head body and a second end for closing the through-port. The utility model assembles a section of excitation rod on the tightening rod. During the tightening operation, the screw is sent into the through-channel through the screw channel, and then the excitation rod is pushed by the tightening rod to push the screw forward along the slideway. The two jaws automatically separate. After being separated from the jaws, the screw is still adsorbed on the front section of the round rod due to magnetism until it enters the product hole, and the tightening gun starts to tighten.

[0004] However, this device still has some shortcomings in actual use: the nail feeding mechanism of this component is not good, and there are problems such as nail jamming and low nail removal efficiency.

[0005] Therefore, a redesign is urgently needed to solve the above problems. Utility Model Content

The tightening component for tightening the screws is installed below the base 1, and the nail feeding component is installed in front of the base 1. The nail-out direction of the nail feeding component is toward the tightening component. The nail feeding component includes a nail magazine 4 and a nail holding seat. The nail magazine 4 is fixedly connected to the front of the base 1. A nail sorting device for arranging the direction of the screws is arranged inside the nail magazine 4. The nail holding seat is arranged below the tightening component. A nail outlet is arranged at the bottom of the nail magazine 4, and the nail outlet direction of the nail outlet is toward the nail holding seat; the interval between the nail magazine 4 and the nail holding seat of the gun head is relatively close, and the short transportation distance of the screws from the nail magazine 4 to the nail holding seat greatly reduces the possibility of the screws getting stuck in the transportation pipeline, solves the problems of easy jamming of nails and low nail-out efficiency in the prior art, improves the practicality and work efficiency of the gun head, and the high degree of cooperation between the tightening component and the nail feeding component further improves the work efficiency of the gun head and saves a lot of labor costs.

[0026] Among them, the nail holding seat includes a left nail seat 6 and a right nail seat 7, the left nail seat 6 and the right nail seat 7 are arranged face to face, the top ends of the left nail seat 6 and the right nail seat 7 are hinged to the base 1, electromagnets are arranged at the bottom ends of the left nail seat 6 and the right nail seat 7, and a compression spring is arranged between the left nail seat 6 and the right nail seat 7; when a screw is placed between the left nail seat 6 and the right nail seat 7, the electromagnet is attracted to achieve stable fixation of the screw, and when the cutter head 2 absorbs the screw between the left nail seat 6 and the right nail seat 7, the electromagnet is powered off, and the left nail seat 6 and the right nail seat 7 are opened under the action of the compression spring.

[0027] The tightening assembly includes a cutter head 2 and a connecting rod 3, one end of the connecting rod 3 is rotatably connected to the base 1, the connecting rod 3 is provided with rotational power by a motor, and the other end of the connecting rod 3 is fixedly connected to the cutter head 2.

[0028] Furthermore, the connecting rod 3 is rotatably connected to the base 1 through a chuck, the connecting rod 3 is detachably fixedly connected to the chuck, and the chuck is rotatably connected to the base 1; the connecting rod 3 is rotatably connected to the base 1 through the chuck, so that different types of cutter heads 2 can be installed on the base 1, greatly improving the versatility of the gun head.

[0029] Optionally, a sensor is provided at the nail holding seat; the function of the sensor is that when the cutter head 2 reaches the nail holding seat and the cutter head 2 absorbs the screw, the sensor controls the bottom end of the left nail seat 6 to separate from the bottom end of the right nail seat 7, thereby completing the tightening action.

[0030] Furthermore, the gun head also includes a horizontal rail 9 and a vertical rail 10. The horizontal rail 9 is horizontally arranged and fixedly connected to the ground, the vertical rail 10 is slidably connected to the horizontal rail 9 and is vertically arranged, and the base 1 is slidably connected to the vertical rail 10; the vertical rail 10 and the horizontal rail 9 allow the base 1 to move freely in the X-axis direction and the Z-axis direction, thereby improving the flexibility of the gun head.

[0032] Preferably, the base 1 also includes an audible and visual alarm 5. When a device fails, the audible and visual alarm 5 can sound an alarm, so that the staff can repair it in time to avoid causing greater losses.

[0033] When the gun head is working, the screws in the nail magazine 4 pass through the nail outlet to the nail holding seat, the nail holding seat fixes the screws, the horizontal rails 9 and the longitudinal rails 10 drive the base 1, and the base 1 drives the cutter head 2 to the nail holding position. After the cutter head 2 absorbs the screws between the left nail seat 6 and the right nail seat 7, the electromagnet is powered off, and the left nail seat 6 and the right nail seat 7 are opened under the action of the compression spring, and the cutter head 2 rotates to complete the tightening of the screws. When the sensor senses that there is a height deviation when the cutter head 2 reaches the nail holding position, the height fine-tuning rail 8 slides slightly between the two side rails, so that the cutter head 2 reaches the appropriate position.

[0034] The above description is only an implementation method of the present utility model, and does not limit the patent scope of the present utility model.
