Description

Automatic strike hammer}

The present invention relates to an automatic striking hammer that can automatically strike an object without using any part of the body when it is desired to deform it.

Humanity has developed along with tools, and methods of hitting objects have also evolved. Methods of adding parts to an object or modifying it using physical force to perform a desired function are also being developed, and a commonly used tool is the hammer. The tool applied to the core of the present invention is a hammer. Types of hammers include hammer, hammer, and hammer. And materials include iron, wood, rubber, and plastic. A component that has been used as an essential part in using a hammer is a nail. In the case of traditional hammers with metal attached to wooden handles, it is difficult to use unless you are skilled, so you may not attempt even simple tasks or ask others to do them. In addition, sufficient movement is required to make a sure hit, and a large space is required. In addition, accuracy is inversely proportional to the size of the force, which can lead to injury and damage to the target.

Recently, a method has been used to use compressed air to momentarily push a pestle out so that the pestle hits the nail, and then pushes it out to secure the nail to the object. Its size also allows it to be held with one hand, so it has been adopted as a tool for field use. there is.

However, only nails that can be mounted on the machine can be used, not the previous nails, so the use of the machine is limited to dedicated nails. Some tools have been manufactured that can hit traditional nails with electric power, but the driving method and advantages and disadvantages are different from those of the present invention, so we would like to submit a manual. The product we looked for has the object striking part hidden inside the machine, and the shape of the object striking is also constant. In the present invention, the striking part of the machine is exposed to the outside to enable more detailed work, and parts corresponding to the hammer can be replaced, enabling flexible use as well as delicate work.

The present invention was proposed to solve the problems of the prior art as described above, and provides an automatic striking hammer that can hit accurately, does not require large force, can be used in narrow spaces, and is easy to use. The purpose is to

Figure 1 is a structural diagram of an automatic hitting hammer using compressed air. Compressed air is collected in the handle 11 of the main body 22 through the air connector 10 connected to the automatic hitting hammer, and the trigger 12 is used. When pulled, the valve 13 opens and compressed air is supplied to the rear of the air pressure transmission plate 14 through the connection passage. As the air pressure transmission plate 14, which is slidably provided in the front-back direction in the first chamber 22-1, advances, the strike 15 advances.
The strike spring 16 provided in the first chamber 22-1 when the strike 15 is inserted is compressed as the air pressure transmission plate 14 advances. The instantaneously moving ball (15) moves forward and hits the hammer fixing assembly (17), transferring kinetic energy. The hammer fixing assembly 17 is provided to be able to slide forward and backward in the second chamber 22-3 formed in the main body 22 in front of the first chamber 22-1. A hammer spring 18, which is a coil spring, is provided in the second chamber 22-3 in front of the hammer fixing assembly 17.
The first chamber 22-1 and the second chamber 22-3 are connected by a guide hole 22-2 with a small cross-sectional area. Air (15) is slidably inserted into the guide hole (22-2).
A hammer member guide hole 22-4 with a small cross-sectional area is formed in front of the second chamber 22-3. The hammer spring 18 is compressed between the front jaw of the second chamber 22-3 and the hammer fixing assembly 17.
The hammer fixing assembly (17) that has been hit moves forward, pushes the hammer member (19) forward, compresses the hammer spring (18), and moves forward. The hammer fixing assembly (17) stops when it meets the striking stop device, and at this time, the movement of the automatic striking hammer stops. The hammer member 19 has energy while moving and can change the striking object. When using a regular nail, energy can be transferred to the nail so that it can be driven into the target. After completing the process and releasing the trigger (12), the valve (13) closes and the compressed air is cut off. Afterwards, the pressure behind the air pressure transmission plate (14) is lowered, and the pressure relief plate (20), which was closed due to the momentary high pressure, is opened and the compressed ball spring (16) and hammer spring (18) are forced to return to their original shape. The air behind the air pressure delivery plate (14) is discharged and the components return to their original positions.

This procedure is a one-time process and operates repeatedly each time the trigger is pulled. The repetition of movements operates very quickly, allowing repetitive tasks to be performed much faster than with a manual hammer.

2 and 3 show an automatic hammer using electricity, which operates after electricity is supplied through a wire 50 or a battery 40 is installed. When electric energy is supplied or the trigger 42 is pulled after the battery 40 is mounted on the handle 41, the electric energy is transmitted to the electric coil 44 through the electric control chip 43. At this time, magnetism is generated in the electric coil (44) and the ball (46) is attracted to the center of the electric coil (44). The hammer (46) moves forward by compressing the hammer spring (45), the hammer (46), which moves momentarily, hits and pushes the hammer fixing unit (47), and the hammer fixing unit (47) moving forward moves the hammer spring ( 48) is compressed and the hammer member 49 is pushed out and moves forward. The moving hammer fixing assembly (47) meets the stop device and stops, and the machine operation stops. The hammer member 49 has energy while moving and can change the striking object. When using a regular nail, energy can be transferred to the nail so that it can be driven into the target. After completing the process, when the trigger (42) is released, the electric energy is cut off, the magnetism in the electric coil (44) disappears, and the compressed ball spring (45) and hammer spring (48) return to their original form by force. They return to their original positions.

This procedure is a one-time process and operates repeatedly each time the trigger is pulled. Repetition of movements operates very quickly, allowing repetitive tasks to be performed much faster than with a manual hammer.
As shown in Figures 2 and 3, an electric coil 44 is provided in the main body 57 having a handle 41, and a first chamber 52 is formed behind it. A second chamber 53 is formed in front of the electric coil 44, in which the hammer fixing assembly 47 is slidable back and forth. A hammer member guide hole 54 extending with a small cross-sectional area is formed in front of the second chamber 53. The first chamber 52 and the second chamber 53 are connected by a guide hole 51 that has a small cross-sectional area and extends in the front-back direction. The strike 46 is slidably inserted into the guide hole 51 through the electric coil 44 and strikes the rear of the hammer fixing assembly 47. A hammer member 49 is provided in the hammer member guide hole 54 to be able to slide forward and backward.
