Definitions
- the present invention relates to a driving machine, and more particularly to a driving machine provided with a weight.
- Patent Document 1 A driving machine provided with a motor for storing energy is known (Patent Document 1).
- elastic energy is accumulated in the spring by driving the motor, and the plunger 7 is accelerated in the striking direction by releasing the elastic energy, and the stopper is driven into wood, gypsum board, or the like. It is driven into the material.
- the driving operation is performed in a state where the injection port is in contact with the material to be driven.
- an object of the present invention is to provide a driving machine that reduces the recoil generated in the driving machine main body, is excellent in operability and has a good finishing degree.
- the present invention provides a nose portion 3 provided in the housing 2 and extending in the longitudinal direction and capable of firing a stopper, and the nose moving in a striking direction parallel to the longitudinal direction.
- the plunger 7 that strikes the stopper through the portion 3, the weight 8, and compressed in the longitudinal direction by a motor, and the plunger 7 is moved in the striking direction by releasing the compression, and the weight 8 is moved to the plunger 7.
- An elastic member that moves in a counter-blowing direction that is further away, wherein the elastic member is provided between the plunger 7 and the weight 8 and is out of both ends in the longitudinal direction.
- the driving machine is characterized in that one end portion biases the plunger 7 and the other end portion biases the weight 8.
- the elastic member when the stopper is driven using the driving machine 1, the elastic member is compressed in the longitudinal direction by the motor, and then when the compression is released, the elastic member accumulates the plunger by the elastic energy accumulated. 7 moves in the striking direction, strikes the stopper and drives it into the material to be struck, and the weight 8 moves in the anti-striking direction. Accordingly, the forces generated by the movements of the plunger 7 and the weight 8 cancel each other and no reaction force acts directly on the housing 2, so that the housing 2 is prevented from being lifted from the driven material. Accordingly, the driving operation can be completed while maintaining the state in which the nose portion 3 is directed to the workpiece, and the operability of the driving machine can be improved.
- the housing 2 does not rise above the driven material when the stopper is driven, the user can perform the driving work without excessively pressing the nose portion 3 against the driven material.
- the occurrence of pressing traces on the material can be reduced, and the finish after the stopper is driven into the material to be driven can be improved.
- the elastic member is provided between the plunger 7 and the weight 8, the configuration is simple, and the driving machine can be manufactured at low cost.
- the elastic member only urges the plunger 7 at one end portion in the longitudinal direction and urges the weight 8 at the other end portion, the lifting of the housing 2 from the driven material during the driving operation is suppressed.
- the stroke of the plunger 7 can be ensured by appropriately setting the weight of each of the plunger 7 and the weight 8.
- the elastic member is a single coil spring. Since the plunger 7 and the weight 8 can be moved by a single coil spring, the total number of parts can be reduced and the driving machine can be manufactured at low cost.
- it has a drive mechanism that compresses the elastic member in the longitudinal direction by the motor, and the drive mechanism releases the compression of the elastic member to move the plunger 7 in the striking direction, and The movement of the weight 8 in the counter hitting direction is started simultaneously.
- the motor has a drive mechanism that compresses the elastic member in the longitudinal direction by the motor, and the drive mechanism releases the compression of the elastic member from the other end side to counter-blow the weight 8. After the movement in the direction is started, the compression of the elastic member from the one end side is released, and the movement of the plunger 7 in the striking direction is started.
- the weight 8 starts moving in the counter-blowing direction, so that the nose portion 3 of the housing 2 is pressed against the material to be driven in the striking direction by the reaction force. Therefore, the nose portion 3 is prevented from deviating from the target driving position of the stopper.
- the force generated by the movement of the weight 8 in the counter striking direction is offset with the force generated by the movement of the plunger 7 in the striking direction. Pushing into the workpiece is stopped. Therefore, in particular, when driving the stopper toward the side surface or the upper surface of the workpiece, the nose portion 3 is not excessively pressed against the workpiece, and the target position of the workpiece to be driven of the nose portion 3 is not exceeded.
- the driving operation can be performed while preventing the deviation. Therefore, generation
- a weight restricting member provided on the housing 2 for restricting further movement of the weight 8 in the counter-blowing direction is further provided, and after the stopper 7 is driven by the plunger 7, the weight 8 is the weight. Abuts on the regulating member.
- the weight 8 comes into contact with the restricting member after the stopper is driven, so that the force generated by the movement of the weight 8 in the counter striking direction after the stopper is driven acts on the housing 2 as a reaction force. . Due to this reaction force, the housing 2 is lifted from the material to be driven after the stopper has been driven, so that the surface finish of the material to be driven can be improved.
- a plunger restricting member that is provided in the housing 2 and restricts the movement of the plunger 7 in the striking direction is further provided, and the moving distance of the plunger 7 to the plunger restricting member is the weight of the weight 8.
- the plunger and the weight are provided in the housing so as to be longer than the moving distance to the regulating member.
- the moving distance of the weight 8 can be shortened while ensuring a stroke necessary for driving the stopper, and thus the housing 2 of the driving machine can be reduced in size.
- the force generated by the movement of the plunger 7 in the striking direction can be canceled out by the force generated by the movement of the weight 8 in the counter striking direction, thereby suppressing the action of the reaction force on the housing 2.
- An excellent effect of being able to do so can be achieved.
