New description: [New technical field] This is a technical field related to a gearbox such as a milling machine, a drilling machine, a boring machine, a gantry machine or a CNC machine, especially a gearbox that can be greatly reduced. The cross-sectional area of the gearbox is such that it is less space-consuming, and the gearbox improvement structure of the processing machine can reduce the noise and reduce the processing cost. [Prior Art] - The structure of the shift gear box 91 of the conventional processing machine 9G is as shown in the fifth figure. 'It is mainly used in the center of a box 92. The input shaft 93, the output shaft 94 and the transmission are arranged in parallel. The shaft 95' then cooperates with the gears 96a, 96b, %c, 96d, 96e that control the different numbers of teeth on the shafts to achieve the purpose of shifting. However, since the input shaft 93, the output shaft 94, and the transmission shaft are disposed in parallel to the collision, the purpose is to accommodate the input shaft (10), the output shaft 94, the transmission shaft 95, and the upper portion thereof. The gears 9 such as 96b, 96c, 96d, 96e, etc., must have a relatively large area of the cross-section of the casing 92, and thus the shift gearbox 91 will be older, and There will also be greater noise and higher production costs. In view of this, Tatsuo Renxian County developed and designed this creation in response to the above-mentioned 嶋=in-depth conception, and actively researching and improving the trial. M442227 [New Content] The main purpose of this work is to provide a surface that can greatly reduce the cross-section of the shifting gearbox. This makes it less space-consuming and can reduce the improved structure of the gearbox. The manufacturing structure of the shifting gearbox of the processing machine of the present invention includes a casing, a driving motor, an input shaft, an output shaft, a shifting shaft, a interlocking gear and a coupling member. Among them, the touch is located above the main axis of the "guard". The drive motor is disposed above the housing and the shaft extends into the housing. The input shaft is coupled to the shaft, and an input gear is fixed to the input shaft. The output shaft is axially rotatably disposed in the housing, the output shaft is concentric with the input shaft, and the upper end of the input (10) is rotatably coupled to the lower end of the input shaft. An output gear is fixed on the output shaft, and the lower end of the output shaft can be rotated under the lower end body. The shifting sleeve is disposed in parallel, the output shaft and one side of the input shaft, and the upper and lower ends are respectively rotatably coupled to the box, and the shifting shaft is fixedly engaged with the output gear. Transmission gear. The linkage is recorded by the Wei Society, and the linkage gear can be controlled by the outside of the casing to move axially on the shifting shaft to spray or disengage the input gear. The connecting member is disposed on the output shaft and rotatable therewith, and the coupling of the cow's top mask and a slot is adapted for the input gear to be engaged to cause the connecting member to be driven by the wheel-in gear. The axial movement of the interlocking gear is synchronized with the axial movement on the output shaft. When the interlocking gear is disengaged from the input tooth M442227, the connecting member can be axially moved to a position where the tooth slot is provided for the input gear, and the connecting member and the driving wheel are arranged. The remaining axial movement moves to a position away from the input gear. By doing this, the output shaft is disposed concentrically below the input shaft, and then the linkage gear is used to control whether the wheel shaft is transmitted to the output shaft through the shift shaft to control the output of the shaft. The output shaft is connected to the aging step, and if the idling input shaft and the output shaft are in the same-axis, the cross-section of the shifting gearbox can be greatly reduced. The area, which in turn makes it less cumbersome, can reduce the noise and cost of the shifting gearbox. [Embodiment]

On the shaft 21, . In the present invention, the wheel input shaft 30 is sleeved and fixed to the drive motor 2 at the lower end of the input shaft 3G. The input gear 31 can also be combined in the input shaft 3〇. on. The output shaft 40 is axially rotatably disposed in the casing 10. The output shaft 40 is coaxial with the input shaft 3〇, and the upper end of the output shaft 4〇 is rotatably coupled to the input shaft 3Q. The lower end. The lower end portion of the output shaft 40 is fixed by a key groove and a key, and the lower end of the output shaft 40 is extended to the lower side of the casing 1 随, which can be used for interlocking the processing. The spindle 81 of the machine 80 rotates. The shifting shaft 50 is disposed in parallel on the output shaft 4'' and the input side 3', and the upper and lower ends are rotatably coupled to the casing 1''. The lower end portion of the shifting shaft 50 is fixed to a transmission gear 51 which is coupled to the output gear μ by a key groove and a key. In addition, in the present creation, the transmission gear 51 can also be formed integrally with the shifting shaft 5G, as shown in the fourth figure. The interlocking gear 60 is disposed on the shifting shaft 5〇 to rotate with the shifting shaft 5〇. The interlocking gear 60 can be externally controlled by the casing 10 to axially move on the shifting shaft 50 to interact with the input gear 31. The phase is combined or detached. In the present invention, a plurality of axial toothed grooves may be disposed on the circumferential surface of the shifting shaft 50, and the inner hole of the interlocking gear 60 may be provided with a plurality of bumps respectively embedded in the plurality of toothed grooves. Thus, the interlocking gear 60 can be rotated by the shifting shaft 50, and the interlocking gear 60 can also move axially on the whip 5Q. The connecting member 70 is disposed on the output shaft 4〇 and is rotatable with the output (four). The top mask of the connecting member 70 is provided with the slot 71 for the input gear & to embed the connecting member 70. The belt 31 can be moved axially in synchronization with the output shaft 4〇 with the axial movement of the interlocking gear 60, and the link 7G can be displaced by the shaft groove 71 for the input gear 31 to be embedded. Or the location of the departure. In this creation, the circumferential surface of the output shaft 4〇 can be set to reduce the axial tooth position, and the bribe knot 7q _ hole system can be separately slidable _ _ _ _ _ _ _ _ _ The output shaft 4 can be rotated, and the connecting member 70 can also move axially on the output shaft 40. In the second figure, the gear ratio of the input gear 31 to the interlocking gear 60 is 127. When the interlocking gear 6 (3 is moved downward to be slid into the connecting gear 31, the connecting member 70 will be downwardly moved downward to make the detachment; the detachment of the gear 31 so that the wheel (4) is The output shaft 40 can thus be rotated accordingly. The drive motor (four) shaft 21 will drive the input shaft _ 'the _ 30 money over the young 31 _ the wheel 6 just; = even: the shift shaft 5 ° rotation, with The above-mentioned gear ratio is known to be that the T3嶋2_' object (four) is rotated one turn. The shaft yoke of the 41 is again coupled to the output gear through the transmission gear 51: when the shaft is yin When the output shaft 40 is linked by it and is rotated 4 times, the output shaft 40 is rotated one turn to achieve the purpose of deceleration. In the third circle, the buckle is buckled, „ ' 9 When the interlocking gear 60 moves upward and disengages from the input gear 31 of the M442227, the connecting member 70 moves upwardly to engage the slot 71 with the input gear 31, so that the input shaft 30 can be thereby The connecting member 70 directly drives the output shaft 40 to rotate ' without driving the interlocking gear 6〇, and only rotates the shifting shaft 50. Thus, The input shaft 30 and the output shaft 4 will thus have the same rotational speed. Since the output shaft 40 of the present invention is coaxially disposed directly below the input shaft 3〇, the cross-section of the shift gear box can be greatly reduced. The area of the section, so that it can be used less space, and the noise and cost of the gearbox can be reduced. In summary, the present invention has the above advantages and practical value, and is similar. No similar product has been published in the product, so it has met the application requirements of the new patent, and is submitted according to law.
