Description

Screw material guiding device of boring machine

The invention relates to a screw material guiding device of a boring machine, in particular to a screw material guiding device of a boring machine which can laterally block the screw material passing through the material blocking device.

When the boring machine performs the boring operation of the screw material, the screw material must be guided and conveyed sequentially by the guiding device, and then the screw material is pushed to the fangs by the stopper device and the pushing device. The device performs cavities, but when the screw material is about to be pushed by the pushing device, the skewing is likely to occur and the accuracy of the cavities is not good. Please refer to FIG. 1 , which shows an inner guide 11 and an outer guide. The plate 12, and an extension member 13 fixed on the inner guiding plate 11, in order to allow the blocking device (not shown) to smoothly carry out the material, the lower part of the extending piece 13 is hollowed out, but the screw moved here The material 14 is easily skewed laterally due to the vibration of the machine. At this time, when the pushing device (not shown) is pushed to the dent device (not shown), the material is also skewed. Therefore, the conventional screw material guiding device cannot be used. The absence of the lateral retaining screw material 14 results in poor accuracy of the cavities and increases the defect rate of the screws.

Accordingly, it is an object of the present invention to provide a screw material guiding device for a denturing machine which can reduce the defective rate.

Therefore, the screw material guiding device of the boring machine of the invention is used for guiding the screw material to continuously move through one of the squeezing device and the squeezing device of the boring machine, and the device is pushed by one gear The screw material is pushed into the dentition device of the boring machine to perform squeezing, and the screw material guiding device has an inner guiding plate, an outer guiding plate, an extending member and a side abutting member, the inner guiding plate and the outer guiding plate The guide plates are arranged in parallel at intervals, and a guiding space for accommodating the screw material is formed between the two, and each has an inner discharge end and an outer discharge end adjacent to the material blocking device, and the outer discharge end is longer than the inner discharge end. The extension member is fixedly disposed above the inner discharge end, the side abutting member is movably disposed at the inner discharge end and located below the extension member, and the extension member and the side abutment member form a block. a material space, the material space of the material blocking device is configured to pass a material blocking material, and the side contact member and the outer guiding plate are spaced apart to form a limiting space for restricting lateral movement of the screw material; The side abutting member is disposed between the material blocking device and the pushing device, so that the screw material does not be skewed during the whole movement, and the pushing device can positively push the screw material to the tooth device to ensure the accuracy of the tooth decay. And can effectively reduce the non-performing rate of the screw.

Referring to Figures 2 to 5, in a preferred embodiment of the present invention, the screw material guiding device 2 of the boring machine 4 and the squeezing device 4, a squeezing device 42, and a squeezing device 43 In combination, it is mainly used to guide the conveying screw material 3 to the material blocking device 41 and the pushing device 42, and push the screw material 3 into the tooth device 43 to perform tooth decay by one step and one push, and the gear is blocked. The material device 41 and the pushing device 42 respectively have a baffle plate 411 and a pusher plate 421. The screw material guiding device 2 has an inner guiding plate 5, an outer guiding plate 6, an extending member 7 and one side. The inner guiding plate 5 and the outer guiding plate 6 are arranged in parallel, and a guiding space 9 for accommodating the screw material 3 is formed therebetween, and each has an inner discharging end close to the blocking device 41. 51 and an outer discharge end 61, and the outer discharge end 61 is longer than the inner discharge end 51, the inner discharge end 51 of the inner guide plate 5 is concavely designed above, and a guide groove 52 is recessed on the side surface thereof, and is guided Two screw holes 53 are defined in the slot 52, and the extension member 7 is used for extending the lead screw material 3, and has a joint portion 71 fixed on the upper end of the inner discharge end 51, and a joint The guiding portion 72 of the joint portion 71 extending thinly is locked to the inner discharge end 51 by two bolts 73, and the joint portion 71 and the guiding portion 72 are aligned with the inner guiding plate 5, The side abutting member 8 is movably disposed at the inner discharge end 51 and below the extension member 7, and is formed with a connecting portion 81, and a guide rail 82 and a side stopper portion 83 extending from the connecting portion 81, the connection A long slot 811 is formed in the portion 81 and extends through the screw holes 53. The guide rail 82 is slidably disposed in the guide slot 52, and is screwed through the slotted hole 811 by a locking member 84. In the screw hole 53, the connecting portion 81 is locked to the inner discharge end 51, and the side stop portion 83 is just outside The outer discharge end 61 of the guide plate 6 is spaced correspondingly to form a limiting space 85 for restricting the lateral movement of the screw material 3, and a blocking space 86 is formed between the extension member 7 and the blocking material space 86 is blocked. The baffle plate 411 of the material device 41 passes through the stopper.

The screw material guiding device 2 of the present invention can adjust the height of the side abutting member 8 relative to the inner guiding plate 5 according to the length of the screw material 3 before use. For example, the length of the screw material 3 shown in FIG. 6 is longer than that of the fifth. The position shown in the figure is long. Therefore, the position of the side abutting member 8 has to be adjusted in advance. The adjustment process needs to first loosen the locking member 84. The side abutting member 8 can be guided by the guide rail 82 and the guide groove 52. The linear adjustment position is up and down. When the adjustment is made to the proper position, the locking member 84 is screwed into the corresponding screw hole 53. If the screw material 3 is longer as shown in FIG. 7, the locking member 84 can be selected. The screw hole 53 is disposed on the lower side of the screw hole 53 so as to further move the side abutting member 8 downward. It is further noted that the adjusting movement position of the side abutting member 8 is premised on being able to block the lower end of the screw material 3.

When the screw material 3 moves in the guiding space 9 between the inner guiding plate 5 and the outer guiding plate 6, it is intermittently blocked by the blocking plate 411 one by one, and the screw is detached from the screw material 3 when the blocking plate 411 is left. The material 3 passes through the baffle plate 411 immediately, and enters the limiting space 85 between the side stop portion 83 and the outer guide plate 6. At this time, the lower end portions of the screw material 3 are respectively subjected to the side stop portion 83 and the outer guide plate 6 respectively. The limit of the screw material 3 is not caused to be skewed, and then the pusher plate 421 pushes the screw material 3 to the tooth decay device 43 for tooth decay as shown in Fig. 8. Therefore, the screw material guide device 2 of the present invention borrows The side abutting member 8 is disposed between the baffle plate 411 and the pusher plate 421 so that the screw material 3 does not become skewed during the entire movement of the screw material 3, and the pusher plate 421 can positively push the screw material 3 to the tooth removing device 43, In order to ensure the accuracy of the tooth decay, the screw defect rate can be effectively reduced.

Supplementary explanation, referring to Fig. 7, when the screw material 3 is long, the side abutting member 8 is relatively adjusted downward, and at this time, the material space 86 is increased, and the material blocking plate 411 can also be adjusted downward. The entire position, and the adjustment mechanism of the baffle 411 is not a feature of the present invention, and therefore will not be described herein.
