fig. 2 is a schematic structural view of a straight bevel gear drilling machine provided by the invention in a discharging state in a specific embodiment.
Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.
Reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
As shown in fig. 1 and 2, in one embodiment, the straight bevel gear drilling machine according to the present invention includes a horizontally disposed upper fixing plate 2, and a horizontally disposed lower fixing plate 7 located below the upper fixing plate 2.
A vertical rack pressure shaft 1 penetrates through the middle of the upper fixing plate 2, and a vertical rack is axially arranged on the rack pressure shaft 1. One side of the rack pressure shaft 1 is provided with a rotary wheel disc 3, the middle part of the rotary wheel disc 3 is provided with a gear, the gear is meshed with the rack, and the rotary wheel disc 3 drives the rack pressure shaft 1 to move up and down through the gear and the rack.
Two ends of the lower fixing plate 7 are respectively connected with a vertical positioning guide pillar 6, and the positioning guide pillar 6 is sleeved with a floating template 4 capable of sliding up and down along the positioning guide pillar 6. And a gear cavity for accommodating a straight bevel gear to be drilled is arranged at the central position of the floating template 4 in a penetrating manner. The center of the lower fixing plate 7 is connected with a vertical drill rod 8. The rack pressure shaft 1, the gear cavity and the drill rod 8 are coaxially arranged. When the floating template 4 slides downwards, the upper end of the drill rod 8 can extend into the gear cavity.
In this embodiment, the floating template 4 is provided with a connecting hole, the aperture of the connecting hole is larger than the diameter of the cross section of the positioning guide pillar 6, the upper end of the positioning guide pillar 6 penetrates through the connecting hole and extends upwards out of the floating template 4, the upper end of the positioning guide pillar 6 is sleeved with a nut, and the diameter of the nut is larger than the aperture of the connecting hole.
Referring to fig. 1, when a drilling operation needs to be performed, a straight bevel gear to be drilled is first placed in the gear cavity, then the rotary wheel disc 3 is rotated, and the rotary wheel disc 3 drives the rack pressure shaft 1 to move downward until the lower end of the rack pressure shaft 1 contacts the straight bevel gear. And continuously driving the rack pressure shaft 1 to move downwards, wherein the lower end of the rack pressure shaft 1 presses the floating template 4 to enable the floating template to slide downwards until the upper end of the drill rod 8 is abutted against the straight bevel gear.
And starting the drill rod 8, starting the drill rod 8 to drill the straight bevel gear, and continuously driving the floating template 4 to press down to ensure that the drill hole is in place during the drilling process.
