The invention relates to a pushing device for a boring machine, in particular to a pushing device for a boring machine capable of shortening a power transmission path.

Press, the pushing device of the general boring machine is used to push the screw material into the squeezing device for squeaking operation, and in the process of pushing the material, the pushing plate of the pushing device is worn due to direct contact with the screw material, Therefore, the pusher plate must be trimmed after being used for a period of time, so that the length of the pusher plate is slightly shortened to increase the push stroke, so the push stroke must be shortened to compensate, so the push stroke of the push device is finely adjusted. The mechanism should be optimized for easy and quick and correct positioning. Please refer to Figures 1 and 2, the conventional pushing device 1 is driven by a transmission device 2, and has a linearly sliding pusher. a base 12, a pusher plate 13 fixed to the front end of the pusher base 12, and a linking member 14 fixed to the pusher seat 12, and the transmission device 2 has a reciprocating pivoting drive arm 21, The driving arm 21 includes an upper arm section 22, an arm section 23 that is adjustable relative to the upper arm section 22 and positioned at a different yaw angle, and a bearing 24 that is axially disposed on the lower arm section 23, such that the lower arm section 23 Adjustable yaw angle with respect to upper arm section 22 The purpose is that the upper arm section 22 and the lower arm section 23 are interlocked with each other, and a cam shaft 25 is disposed between the two. In the normal state, the lower arm section 23 is fixed relative to the upper arm section 22, and when the pusher plate 13 performs the pushing operation. If the wear occurs for a period of time, the angular yaw adjustment of the upper and lower arm sections 22, 23 can be performed, so that the pusher seat 12 can shorten the moving stroke, and the pushing operation can be smoother. Relax the upper and lower arm sections 22, 23, then rotate the camshaft 25 is rotated from the second drawing to the position of the third figure, so that the lower arm section 23 is angularly offset from the upper arm section 22, and finally the upper and lower arm sections 22, 23 are locked.

Although the above-mentioned conventional pushing device 1 can achieve the effect of adjusting the pushing stroke of the pusher base 12, the adjustment structure is complicated, not only the adjustment process is troublesome, but also the complicated components are increased in manufacturing, and there is an adjustment. Lack of operation and increased manufacturing costs.

The transmission device 2 further has a transmission rod 26 for driving, and a cantilever arm 27 pivotally connected to the transmission rod 26. The suspension arm 27 forms an angular difference with the driving arm 21, and the power transmitted by the transmission rod 26 is via The cantilever 27 is transmitted to the driving arm 21, thereby driving the pushing base 12 to slide, and the cantilever 27 and the driving arm 21 have an angular difference design, so that the overall structural complexity of the pushing device 1 and the transmission device 2 is improved, and the boring machine is further increased. Manufacturing costs.

Accordingly, it is an object of the present invention to provide a pusher device of a simple construction machine.

Therefore, the pushing device of the boring machine of the present invention is used in combination with other mechanisms of the boring machine, the boring machine having a machine table, and a transmission device and a dent device disposed on the machine table, the pushing material The device is interlocked by the transmission device to push the screw material to the tooth device for performing the tooth decay operation, and has a fixing seat fixed on the machine table, a sliding seat reciprocally sliding relative to the fixing seat, and a device disposed on the sliding seat An elastic member between the fixed seat and the sliding seat, a swing arm pivoted on the machine table, a pushing member extending upward from the swing arm, and a push component disposed under the sliding seat, the pendulum The arm system is pivotally connected with the linkage rod to form a pivoting point, and the pivoting point is corresponding to the lower pushing member, and the swing arm can be pivoted by the linkage rod to make the pushing member Push the push And the component is further slidably moved relative to the fixed seat to perform a non-pushing stroke. When the pushing member is not pushed against the pushing component, the sliding seat is pushed by the elastic component to slide relative to the fixed seat to perform a pushing stroke; When the swing arm is pivoted by the linkage rod, the pushing member above the swing arm directly pushes against the pusher assembly, so the structure is simple compared with the conventional structure, and the manufacturing cost can be greatly reduced.
