Referring to Figures 1 to 4, in a preferred embodiment of the present invention, the pushing device 2 of the boring machine 1 is used in combination with a feeding channel 11 for intermittently removing the screw material leaving the feeding channel 11. The pushing device enters between the two dental plates 12 to perform the caulking operation, and the pushing device 2 and the feeding channel 11 are respectively erected on a machine table 13 of the boring machine 1, and a long slot is formed in the machine table 13. 131. In addition, the linkage device 14 of the boring machine 1 is configured to transmit power to the ejector device 2, so that the ejector device 2 performs a pushing operation, and the linkage device 14 has a swing arm capable of transmitting power. 141 and a pivoting member 142 pivotally connected to the swing arm 141. The structure and transmission mode of the swing arm 141 and the pivoting member 142 are not characteristic of the present invention, and therefore, the pushing device 2 has a fixing base. 3. A pusher base 4, an elastic member 5, a linkage member 6, and a transmission mechanism 7.

The fixing base 3 is fixed to the machine table 13.

The pusher base 4 is slidably disposed on the fixing base 3 for pushing the screw material between the two dental plates 12.

The elastic member 5 is disposed between the fixing base 3 and the pusher base 4, and when the pusher base 4 is pushed by the external force, the restoring force of the elastic member 5 can push the pusher seat 4 to push the screw The material enters between the two dental plates 12.

The connecting member 6 is fixed on the pusher base 4, and has a fixing portion 61 fixed under the pushing base 4, and a pushing portion 62 extending downward from the fixing portion 61. The pushed portion 62 is inserted into the long slot 131.

The transmission mechanism 7 has a transmission arm 71 pivotally connected to the pivot member 142 and can be driven by the same, and a pusher 72 pivoted by the transmission arm 71. The pusher 72 is coupled to the linkage member. 6 detachably abutting, forming a pivot 721 pivoted on the machine table 13, a The pivoting arm 721 is disposed and coupled to the transmission arm 71. The driving arm 8 is also protruded from the pivoting shaft 721 and angularly offset from the engaging arm 722, and a shaft is disposed on the driving arm 8. A bearing 723 is located in the long slot 131 and is in contact with the pushed portion 62 of the linkage 6.

In the pushing process of the pushing device 2 of the embodiment, the reciprocating moving stroke is performed, and in the third and fourth figures, the stroke of the pushing base 4 by the transmission mechanism 7 is displayed, that is, when the boring machine 1 is When the power of the swing arm 141 and the pivoting member 142 pushes the transmission arm 71, the engaging arm 722 and the driving arm 8 of the pushing member 72 are pivotally pivoted, and the bearing 723 located on the driving arm 8 simultaneously shifts the The pushing portion 62 of the linking member 6 further drives the pushing base 4 to displace and compress the elastic member 5, and at this time, the movement of the pushing base 4 is away from the two dental plates 12, and the stroke of the screw material is not pushed.

Referring to Figures 5 and 6, when the driving arm 8 of the pusher 72 is driven to move in the opposite direction by the linking device 14, that is, the bearing 723 on the driving arm 8 no longer pushes the pushed portion 62 of the linking member 6 At this time, the pusher base 4 is pushed toward the two dental plates 12 by the restoring force of the elastic member 5, and the pushing stroke of pushing the screw material to the two dental plates 12 is performed. It is worth noting that during the pushing stroke The speed at which the bearing 723 moves is faster than that of the pushed portion 62 of the linkage member 6, that is, the two are in a separated state. When the pusher holder 4 completes the pushing stroke, the bearing 723 of the pusher member 72 is again linked. The pushed portion 62 of the member 6 is contacted and moved to perform the next stroke. Therefore, the pusher base 4 of the push device 2 of the present invention can be surely driven by the drive mechanism 7 and the push of the elastic member 5 Smoothly push the screw material between the two dental plates 12 for the purpose of tooth decay.

The pushing member 72 of the transmission mechanism 7 of the pushing device 2 of the present invention is separated from the linking member 6 mainly when the pushing block 4 is in the process of pushing the material or other unsmooth conditions. The pusher base 4 cannot move according to the original predetermined stroke, and the linkage device 14 of the mortise machine 1 can independently operate when the power is transmitted to the transmission mechanism 7, without being affected by the pusher seat 4, so that it can be confirmed The linkage device 14 and the transmission mechanism 7 are protected from damage, that is to say the pusher device 2 has the effect of power transmission buffering to protect the overall transmission configuration.

Referring to Figures 7-9, another embodiment of the present invention has a fixing device 3, a pushing base 4, an elastic member 5, a linking member 6 and a pushing device 2 The main difference of the transmission mechanism 7 is that the driving arm 8 of the transmission mechanism 7 includes an upper arm segment 81 extending from the pivot 721, and an arm segment 82 that is adjustable relative to the upper arm segment 81 and positioned at a different yaw angle. The bearing 723 is axially disposed on the lower arm section 82. The upper arm section 82 is configured to have a yaw angle with respect to the upper arm section 81. The upper arm section 81 is formed with an axial hole 811 and a locking hole 812. And an adjusting slot 813 between the pivot hole 811 and the locking hole 812. The corresponding pivot hole 811, the adjusting slot 813 and the locking hole 812 of the lower arm segment 82 are respectively formed with a shaft through hole 821 and an adjusting hole. The 822 and the long slot 823, the driving arm 8 further includes a central shaft 83, a rotating shaft 84 and a locking shaft 85. The central shaft 83 passes through the shaft through hole 821 and the shaft hole 811 to lower the arm. The segment 82 is pivoted or locked to the upper arm segment 81. In the embodiment, the end of the central shaft 83 is locked to the shaft hole 811, and the pivot shaft 84 is fixed. The shaft portion 841 having an adjusting hole 822 and a cam portion 842 extending from the shaft portion 841 are disposed in the adjusting groove 813. The locking shaft 85 passes through the long slot 823. The lock is locked to the locking hole 812.

In the normal state, the central shaft 83 and the locking shaft 85 are locked, and the lower arm segment 82 is fixed relative to the upper arm segment 81. When the pusher base 4 is pushed for a period of time, the front end thereof is worn. The angular yaw adjustment of the upper and lower arm sections 81 and 82 can be performed, so that the pusher base 4 can be moved slightly toward the feeding channel 11, so that the pushing operation can be made smoother, and the adjustment needs to be performed first. The central shaft 83 and the locking shaft 85 are loosened, and then the rotating shaft portion 841 of the adjusting shaft 84 is rotated to rotate the cam portion 842 from the eighth figure to the position of the ninth figure in the adjusting groove 813, so that the lower arm Segment 82 is centered on central axis 83 The center is angularly offset from the upper arm section 81, and the pusher base 4 is pushed by the elastic member 5 to move in the direction indicated by the arrow in FIG. 9 and remains in contact with the bearing 723. The lower arm is adjusted during the adjustment. The long slot 823 of the segment 82 is designed such that the lower arm segment 82 can be smoothly displaced relative to the locking shaft 85, and finally the central shaft 83 is locked with the locking shaft 85, that is, the upper and lower arm segments 81 are completed. , 82 angle adjustment.
