In order to further understand the effects of the cooperation of the various elements of the present invention, the technical means used, and the expected effects, the following will be explained again, and it is believed that a deeper and specific understanding of the present invention can be obtained from this.

As shown in Figures 1 and 4, it is shown that the cutter 7 is firmly connected to the pull rod 501 And in a machinable state, the input gear 2 is used to transmit power to the output gear 3, the sleeve 4 and the tool 7.

As shown in Figure 5 (in conjunction with Figure 2), when the power is stopped and the tool is to be retracted, the input gear 2, the output gear 3, and the sleeve 4 are stationary, and the retract piston 602 is activated along the first When the two axes L2 move in the direction of the pull rod 501, the retracting piston 602 pushes the pull rod 501 to move relative to the sleeve 4, so that the pull rod 501 can release the tool 7 and perform a tool change operation.

As shown in FIG. 5, during the above-mentioned retracting operation, that is, when the retracting piston 602 moves along the second axis L2 and toward the pull rod 501 (the springs 603 are compressed and hidden Release the elastic force), the retracting piston 602 will push the depressed end 11 of the linkage 10, and cause the linkage rod 10 to slide along the sliding hole 103, and the push end 12 pushes the seal of the sliding sleeve 24 Wall 241, and make the sealing wall 241 approach the end wall 211, the grease originally present in the oil chamber 214 can be squeezed out toward the oil outlet pipe 22 (at this time, the volume of the oil chamber 214 becomes smaller, and the elastic The member 25 is compressed and contains the resilience), and the grease is allowed to pass through the communicating tube 221, the guide channel 222, and finally discharged from the oil outlet 226 to the meshing part of the input gear 2 and the output gear 3. When the next machining stroke starts, the input gear 2 and the output gear 3 can be smoothly meshed, which can reduce wear and extend the use of the input gear 2 and the output gear 3. life. And the grease dripping from the input gear 2 and the output gear 3 will flow back to the bottom 102 of the chamber 101.

And when the tool change is completed, the elastic force of the disc-shaped springs 502 will make the pull rod 501 move in the reverse direction, and the elastic force of the springs 603 will also make the retracting piston 602 return to the original position. At the same time, The elastic force of the elastic member 25 will also cause the sliding sleeve 24 and the linkage member 10 to return to the state of FIG. 2 and FIG. 4. As the sealing wall 241 of the sliding sleeve 24 moves away from the end wall 211, the The oil chamber 214 is changed slightly to generate suction, and the oil returning to the bottom 102 of the chamber 101 is sucked into the oil chamber 214 through the oil suction end 232 of the oil suction pipe 23 to facilitate the next automatic refueling operation.

Therefore, the present invention utilizes the overall configuration. When the retracting cylinder 6 performs the retracting operation, the sliding sleeve 24 can be linked through the linkage 10, and when the sliding sleeve 24 is displaced relative to the housing 21, the sliding sleeve 24 can be moved The grease originally present in the oil chamber 214 is squeezed, and then the grease is squeezed out from the oil outlet 226 of the oil outlet pipe 22, and the purpose of automatically supplying lubricating grease to the meshing part of the input gear 2 and the output gear 3 is achieved.

Compared with the existing additional head, the lubricating grease can be automatically refilled every time the tool is changed, no manpower is required to replenish the grease, and the additional head does not need to be disassembled, which can increase the production capacity.

In summary, the composite head grease backfilling device of the processing machine of the present invention has a simple overall structure, easy manufacturing and assembly, and can achieve the purpose of automatically replenishing lubricating grease, which can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention, and should not be used to limit the scope of implementation of the present invention. Any application for patent scope and patent specification according to the present invention Simple equivalent changes and modifications made to the content are still within the scope of the patent of the present invention.
