Description

脈衝式電動工具傳動及觸動停止裝置(二) Pulse power tool transmission and trigger stop device (2)

本發明涉及電動工具相關之技術領域，尤其是指一種脈衝式電動工具傳動及觸動停止裝置。 The present invention relates to the technical field related to electric tools, and in particular, to a pulse-type electric tool transmission and trigger stop device.

如圖1，油壓脈衝動力工具的先前技藝，油壓脈衝機構94大致包括儲油筒體943置於油室筒體942中，前端蓋944和後端蓋945分別組裝於油室筒體942前後端，油壓轉軸941穿伸前端蓋944後定置於儲油筒體943，後端蓋945與風驅機構92連接，後端蓋945還包括與儲油筒體943連通的溢油道945A與階級式軸孔945B，頂掣桿946的一端插置於階級式軸孔945B中，另端穿伸風驅機構92後對應洩氣開關93。風驅機構92可被電驅機構(電機馬達)取代，而洩氣開關93則被電機馬達的制動開關取代。 As shown in Figure 1, in the prior art of hydraulic pulse power tools, the hydraulic pulse mechanism 94 generally includes an oil storage cylinder 943 placed in the oil chamber cylinder 942, and the front end cover 944 and the rear end cover 945 are respectively assembled in the oil chamber cylinder 942. At the front and rear ends, the hydraulic rotating shaft 941 extends through the front end cover 944 and is positioned in the oil storage cylinder 943. The rear end cover 945 is connected to the wind drive mechanism 92. The rear end cover 945 also includes an oil spillway 945A connected with the oil storage cylinder 943. With the stepped shaft hole 945B, one end of the top lever 946 is inserted into the stepped shaft hole 945B, and the other end extends through the wind drive mechanism 92 and corresponds to the air release switch 93. The wind drive mechanism 92 can be replaced by an electric drive mechanism (motor), and the vent switch 93 can be replaced by a brake switch of the motor.

油壓脈衝機構94作動過程中，其儲油筒體943內之液壓油達到一預設壓力時，會經由溢油道945A進人階級式軸孔945B中形成一推力，進一步推動頂掣桿946朝洩氣開關93(或制動開關)運動，達成觸發停止風驅機構或電驅機構的目的。 During the operation of the oil pressure pulse mechanism 94, when the hydraulic oil in the oil storage cylinder 943 reaches a preset pressure, it will enter the stepped shaft hole 945B through the oil spill passage 945A to form a thrust, further pushing the top lever 946 Move toward the deflation switch 93 (or brake switch) to achieve the purpose of triggering and stopping the pneumatic drive mechanism or the electric drive mechanism.

油壓轉軸941的穩定性非常重要，關鍵取決於後端蓋945與風(電)驅機構92連接關係。通常兩者的連接處被軸承98支撐。基於此，軸承、後端蓋與風(電)機構的空間配置和連接關係需要謹慎的考慮。 The stability of the hydraulic rotating shaft 941 is very important, and the key depends on the connection relationship between the rear end cover 945 and the wind (electric) drive mechanism 92. Usually the connection between the two is supported by bearing 98. Based on this, the spatial configuration and connection relationship between the bearings, rear end cover and wind (power) mechanism need to be carefully considered.

針對油壓轉軸穩定性的問題，本發明提出如下解決方案。 Aiming at the problem of stability of the hydraulic rotating shaft, the present invention proposes the following solutions.

The hydraulic pulse mechanism 30 drives the hydraulic rotating shaft 36 to rotate and tighten a workpiece (not shown).

擰緊工件時，油壓轉軸36承受從工件而來的反作用力，從而增加 了操作扭力，此時，儲油筒體31內之液壓油達到一預設壓力時，會經由溢油道341進人階級式軸孔342中形成一推力，進一步推動觸動桿42朝觸動開關41運動，觸動開關41被觸動桿42觸發，隨即停止電驅機構20。 When tightening the workpiece, the hydraulic rotating shaft 36 bears the reaction force from the workpiece, thus increasing the At this time, when the hydraulic oil in the oil storage cylinder 31 reaches a preset pressure, it will enter the stepped shaft hole 342 through the oil spill passage 341 to form a thrust, further pushing the trigger rod 42 toward the trigger switch 41 movement, the trigger switch 41 is triggered by the trigger lever 42, and then the electric drive mechanism 20 is stopped.

在電驅機構20驅動油壓脈衝機構30運轉的過程中，連軸組件50發揮穩定油壓轉軸36的運轉不偏離軸線Ax的功能。因為，外轉子21延伸部22與連軸件52以螺紋接合，油壓脈衝機構30的後端蓋34又與連軸件52以螺紋接合，據此外轉子21延伸部22、連軸件52、以及油壓脈衝機構30三者對準軸線Ax實現緊密接合；此外，連軸培林51同時旋向限位並支撐外轉子21延伸部22和連軸件52，確保轉子延伸部22、連軸件52、以及油壓脈衝機構30三者恆對準軸線Ax，油壓轉軸36運轉不偏離軸心Ax，具有高穩定性。 When the electric drive mechanism 20 drives the hydraulic pulse mechanism 30 to operate, the coupling assembly 50 plays a function of stabilizing the operation of the hydraulic rotating shaft 36 so as not to deviate from the axis Ax. This is because the extension part 22 of the outer rotor 21 is threadedly engaged with the connecting member 52, and the rear end cover 34 of the hydraulic pulse mechanism 30 is threadedly engaged with the connecting member 52. Accordingly, the extended part 22 of the outer rotor 21, the connecting member 52, and the hydraulic pulse mechanism 30 are aligned with the axis Ax to achieve tight coupling; in addition, the coupling bearing 51 simultaneously limits the rotation and supports the extension 22 of the outer rotor 21 and the coupling 52 to ensure that the extension 22 of the rotor and the coupling 52 The component 52 and the hydraulic pulse mechanism 30 are constantly aligned with the axis Ax, and the hydraulic rotating shaft 36 does not deviate from the axis Ax when operating, and has high stability.
