Description
本發明涉及一種鎖螺絲裝置，尤其涉及一種可自動鎖螺絲並能保證螺絲準確定位之自動鎖螺絲裝置。 The invention relates to a lock screw device, in particular to an automatic lock screw device capable of automatically locking a screw and ensuring accurate positioning of the screw.
產品之間的連接方式，通常有膠粘、鉚接、銷釘連接及螺紋連接等等。最常採用的是螺紋連接。人工鎖螺絲時，需一手持螺絲貼附於工件預鎖合之位置，另一手持起子並用力下壓同時旋轉起子直至鎖緊為止，隨著螺絲逐漸深入工件中，給予起子之扭力需要不斷地增加，因此，人工執行鎖螺絲是相當耗時耗力且不容易均等地控制每一顆螺絲之緊度，尤其不適合於生產流水線上手工操作。 The connection between products is usually glued, riveted, pinned and threaded. The most commonly used is a threaded connection. When manually locking the screw, a hand-held screw is attached to the pre-locking position of the workpiece. The other hand holds the screwdriver and presses the screwdriver while rotating until the lock is tight. As the screw gradually penetrates into the workpiece, the torque given to the screwdriver needs to be continuously Increased, therefore, manual execution of the locking screw is quite time consuming and laborious and it is not easy to control the tightness of each screw equally, especially for manual operation on the production line.
為提升鎖螺絲之作業效率，業者研發了自動鎖螺絲裝置。如一種自動鎖螺絲裝置以微動開關之按壓控制使氣壓由進氣孔進入機體內而推動活動轉軸及起子前進同時轉動起子以達到自動鎖螺絲之目，而放開微動開關時，電磁閥立刻切換進氣孔換成排氣孔，使氣缸內之氣體由進氣管排出，此時活動轉軸受彈力回歸原位置，然而，該種方式中之一待鎖固至一工件上之螺絲(尤指小螺絲)，容易於對準工件時偏移所述工件所處之位置，從而導致螺絲之定位不準確。 In order to improve the working efficiency of the locking screw, the operator developed an automatic locking screw device. For example, an automatic locking screw device is controlled by the pressing of the micro switch to make the air pressure enter the body through the air inlet hole to push the movable shaft and the screwdriver forward while rotating the screwdriver to achieve the purpose of automatically locking the screw, and when the micro switch is released, the solenoid valve switches immediately. The intake hole is replaced with a vent hole, so that the gas in the cylinder is discharged from the intake pipe, and the movable shaft is returned to the original position by the elastic force. However, one of the ways to lock the screw to a workpiece (especially Small screws), it is easy to offset the position of the workpiece when aligning the workpiece, resulting in inaccurate positioning of the screw.

請一起參閱圖5，使用自動鎖螺絲裝置時，將所述輸送件80***所述第一套筒30之進位孔311內，所述螺絲40藉由所述輸送件80滑入所述第一套筒30內，進而滑入所述三定位件50形成之收容孔58內，於滑至所述定位部57時，所述螺絲40之螺帽41被所述定位 部57之定位斜面571所阻擋，所述螺柱43伸入所述三個定位件50之定位槽573組成之定位孔59中。一外力迫使所述起子10以靠近所述螺絲40之第一方向移動，在所述起子10之鎖緊部13卡扣於所述螺絲40之螺帽41的開槽中時，所述外力進一步驅使所述起子10沿所述第一方向滑動，從而使所述螺帽41沿所述定位斜面571滑動並擠壓所述定位斜面571，同時推動所述定位件50向所述第一方向移動，所述彈性元件60因此受到所述卡固部51之擠壓而彈性變形，所述三個定位件50由於受到所述螺絲40之擠壓而逐漸張開。當所述定位件50之卡扣部53由所述角度為76度之第一斜面731滑至並卡扣於所述74度角度之第二斜面733時，可使所述定位件50之定位部57能張開2度之角度，張開之2度角度可使所述螺絲40之螺帽41剛好由所述定位部57之定位斜面571滑落至需要鎖固之工件(圖未示)上。 Referring to FIG. 5 together, when the automatic locking screw device is used, the conveying member 80 is inserted into the positioning hole 311 of the first sleeve 30, and the screw 40 is slid into the first by the conveying member 80. The sleeve 30 is slid into the receiving hole 58 formed by the three positioning members 50. When the sliding portion is slid to the positioning portion 57, the nut 41 of the screw 40 is positioned. The positioning bevel 571 of the portion 57 is blocked, and the stud 43 extends into the positioning hole 59 formed by the positioning groove 573 of the three positioning members 50. An external force forces the driver 10 to move in a first direction adjacent to the screw 40. When the locking portion 13 of the driver 10 is snapped into the slot of the nut 41 of the screw 40, the external force is further Driving the driver 10 to slide in the first direction, thereby sliding the nut 41 along the positioning slope 571 and pressing the positioning slope 571 while pushing the positioning member 50 to move in the first direction The elastic member 60 is thus elastically deformed by being pressed by the fastening portion 51, and the three positioning members 50 are gradually opened by being pressed by the screw 40. When the locking portion 53 of the positioning member 50 is slid by the first inclined surface 731 having an angle of 76 degrees and is buckled to the second inclined surface 733 of the 74 degree angle, the positioning of the positioning member 50 can be performed. The portion 57 can be opened at an angle of 2 degrees, and the angle of the opening of the screw 40 can cause the nut 41 of the screw 40 to just slide off the positioning inclined surface 571 of the positioning portion 57 onto the workpiece (not shown) to be locked.
本發明自動鎖螺絲裝置可根據螺絲40之實際大小而設計不同大小之定位件50，亦可根據螺絲40之螺帽41直徑的實際大小而改變所述第一斜面731及所述第二斜面733的角度之差從而使所述定位件50張開之角度與所述螺帽41配合，使得所述螺絲40能正確定位於待鎖固之工件之上。於另外之實施方式中，所述第一套設筒30與所述第二套設筒70可形成於一體。 The automatic locking screw device of the present invention can design the positioning members 50 of different sizes according to the actual size of the screws 40, and can also change the first inclined surface 731 and the second inclined surface 733 according to the actual size of the diameter of the nut 41 of the screw 40. The difference in angles causes the positioning member 50 to open at an angle to the nut 41 so that the screw 40 can be positively positioned on the workpiece to be locked. In another embodiment, the first sleeve 30 and the second sleeve 70 may be formed integrally.
