Description
本發明係關於一種電動打釘槍之擊釘作動裝置，乃提供電動打釘槍及釘動作穩定、確實之實用功效。 The invention relates to a nailing device for an electric nailing gun, which provides a stable and reliable practical effect of the electric nailing gun and the nail action.
按，請參閱第八圖所示，習用電動打釘槍之擊釘裝置大致如下所述：一馬達(70)、一按壓開關(71)，該馬達(70)具有一傳動軸(72)，傳動軸(72)上接設一凸輪撥桿(73)，一推釘部其設有一擊釘片(74)、一撥片(75)以及一彈簧(77)，該撥片(75)係與一殼體(76)一體包覆於彈簧(77)外側，該凸輸撥桿(73)接觸於撥片(75)上，使撥片(75)與該彈簧(77)同步壓縮及伸展作動，該擊釘片(74)係連設於撥片(75)上方；使用者可藉由作動該按壓開關(71)，進而啟動馬達(70)傳動軸(72)以帶動凸輪撥桿(73)旋轉，該凸輪撥桿(73)藉由掣動力推掣該撥片(75)，並同步壓縮該彈簧(77)逐漸朝擊釘的反方向位移而蓄存彈力；請參閱第九圖所示，當凸輪撥桿(73)的轉動行程越過該撥片(75)時，撥片(75)即不受到凸輪撥桿(73)的推掣，而承靠於該撥片(75)內的彈簧(77)立即釋放彈力；請參閱第十圖所示，該彈簧(77)釋放的動力據以驅動該擊釘片(74)撞擊釘針(78)，使釘針(78)得以擊入該工作件中。 Press, as shown in the eighth figure, the nailing device of the conventional electric nailer is generally as follows: a motor (70), a push switch (71), the motor (70) has a drive shaft (72), A drive lever (72) is connected with a cam lever (73), and a pusher portion is provided with a nail piece (74), a paddle (75) and a spring (77), the paddle (75) Cooperating with a casing (76) integrally on the outer side of the spring (77), the convex transfer lever (73) is in contact with the paddle (75), so that the paddle (75) is compressed and extended synchronously with the spring (77). Actuated, the nail piece (74) is connected above the paddle (75); the user can actuate the push switch (71) to activate the motor (70) drive shaft (72) to drive the cam lever ( 73) Rotating, the cam lever (73) pushes the paddle (75) by the power of the cymbal, and synchronously compresses the spring (77) to gradually shift in the opposite direction of the pin to store the elastic force; As shown, when the rotational stroke of the cam lever (73) passes over the paddle (75), the paddle (75) is not pushed by the cam lever (73) and bears against the paddle (75). The inner spring (77) immediately releases the spring force; see the tenth figure, the spring (77) is released According to the driving force of the striking plate (74) striking the staple (78), so that the staple (78) to be hit into the work piece.
然而，依照上述結構其實具有以下缺點：由於凸輪撥桿(73)及撥片(75)係以頂掣面的接觸，且該凸輪撥桿(73)係以光滑的圓柱體形成，當凸輪撥桿(73)與撥片(75)進行旋轉頂掣時，因受彈簧(77)蓄積彈性作用力的影響，在長期的使用下，二者間係形成強力的磨擦接觸而有磨損之虞，易導致該傳動擊釘的正確性。 However, according to the above structure, there is actually the following disadvantage: since the cam lever (73) and the paddle (75) are in contact with the top surface, and the cam lever (73) is formed by a smooth cylinder, when the cam is dialed When the rod (73) and the pick (75) are rotated, the spring force is exerted by the spring (77), and under long-term use, a strong frictional contact is formed between the two, and there is wear and tear. It is easy to cause the nail to be correct.
本設計者鑑於習用電動打釘槍擊釘作動的缺失，進而用心研究開發，因此本發明的主要目的在於：該推釘部透過齒輪及齒條的傳動以帶動彈力擊釘作業，取代現有以凸輪撥桿及撥片的頂掣擊釘設計，藉以得到一作動確實、穩定的電動打釘槍之擊釘作動裝置者。 The designer's main purpose is to use the transmission of the gear and the rack to drive the elastic nailing operation, instead of the existing cam dialing, in view of the lack of the operation of the electric nailing gun. The top smashing nail design of the rod and the plucking wheel is used to obtain a hammering actuating device for the electric nail gun which is effective and stable.
為了達到前述的目的，本發明所運用的技術手段係在於提供一種電動打釘槍之擊釘作動裝置，其包含一釘槍本體、一馬達、一按壓開關、一推釘部及一彈簧板片所構成；該釘槍本體提供上述元件容置於本體內，該馬達其接設一半月齒輪，該半月齒輪係由馬達驅動者；該推釘部設於釘槍本體內上端，該推釘部具有一滑座及一擊針片，該滑座上端承靠於彈簧板片，該滑座內緣設有對應半月齒輪的齒條，該擊針片樞接於滑座，而該擊針片套設於一導板上；據此，馬達驅動半月齒輪旋轉帶動齒條而令滑座朝擊釘反方向位移且使彈簧板片彎曲，而半月齒輪之齒形行程與齒條脫離嚙合時，該彈簧板片得立即將滑座及擊針片朝擊釘方向位移並擊出釘針，據以獲得擊釘動作正確且穩定之裝置者。 In order to achieve the foregoing objective, the technical means utilized by the present invention is to provide a nailing device for an electric nail gun, comprising a nail gun body, a motor, a push switch, a push nail portion and a spring plate The nail gun body provides the above-mentioned component in the body, the motor is connected to the half moon gear, and the half moon gear is driven by the motor; the nail pushing portion is disposed at the upper end of the nail gun body, and the nail pushing portion is The utility model has a sliding seat and a punching piece, wherein the upper end of the sliding seat bears against the spring plate piece, and the inner edge of the sliding seat is provided with a rack corresponding to the half moon gear, the breaking piece is pivotally connected to the sliding seat, and the shooting piece is pivoted Nested on a guide plate; accordingly, the motor drives the half moon gear to rotate the rack to rotate the slider in the opposite direction of the nail and bend the spring plate, and the toothed stroke of the half moon gear is disengaged from the rack. The spring plate piece immediately displaces the slider and the pin piece in the direction of the nail and strikes the nail, so as to obtain a correct and stable device for the nailing action.
