DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] Reference Figure 1-7The drilling device of this embodiment includes a punching mechanism, a base 2, vertical plates located on both sides of the base 2, a connecting rod 4 connected to the two vertical plates, a rotating rod 5 that can rotate along the connecting rod 4, an operating component for driving the punching mechanism to move along the connecting rod 4, and a limiting mechanism for fixing the drilling position. The vertical plate includes a first vertical plate 31 and a second vertical plate 32. The punching mechanism in this embodiment is a pistol drill 1, and the head of the pistol drill 1 has a drill bit for drilling. Both ends of the connecting rod 4 are fixed to the vertical plates through end covers 13.

[0028] The two sides of the lower end of the vertical plate have hooks 171 extending downward, and there is a receiving groove 172 between the two hooks 171 for receiving part of the truss 19. The base 2 is provided with a fastener 16 for fixing the drilling device on the truss 19 corresponding to the receiving groove 172. The truss 19 is hooked by the hook 171, and the drilling device is fastened to the truss 19 by the fastener 16 to prevent the device from shifting during drilling, resulting in poor drilling. The fastener 16 in this embodiment is a bolt assembly 9, which can be rotated and extended inward, and then locked with the hook 171, and the number of fasteners 16 is two.

[0029] The operating assembly includes a first positioning block 61 and a second positioning block 62 arranged on the connecting rod 4, a slider 63 slidably arranged on the connecting rod 4, a handle 151 rotatably arranged on the first positioning block 61, and a connecting rod 152 rotatably arranged on the slider 63, one end of the connecting rod 152 is rotatably arranged on the slider 63, and the other end of the connecting rod 152 is rotatably arranged on the handle 151, and the pistol drill 1 is slidably arranged on the connecting rod 4 through the slider 63. The first vertical plate 31 is close to the first positioning block 61, and the second vertical plate 32 is close to the second positioning block 62. A fixing sleeve 11 is arranged on one side or both sides of the first positioning block 61 and the second positioning block 62 to fix the position of the positioning block on the connecting rod 4.

[0030] One end of the rotating rod 5 is fixed on the second positioning block 62, and the other end is arranged on the first vertical plate 31 after passing through the slider 63 and the first positioning block 61, and the slider 63 is arranged between the first positioning block 61 and the second positioning block 62. The first positioning block 61 and the second positioning block 62 are fixed to the position of the connecting rod 4, and are used to limit the movement position of the slider 63. Among them, the first positioning block 61 is used to determine the limit position of the slider 63 to retreat, and the second positioning block 62 is used to determine the limit position of the slider 63 to advance, so as to limit the movement range of the pistol drill 1. In this embodiment, a limit sleeve 12 is also provided on the rotating rod 5 between the slider 63 and the first positioning block 61 to control the shortest distance between the slider 63 and the first positioning block 61, so as to prevent the pistol drill 1 from excessive retreat and damage.

[0031] In this embodiment, the first positioning block 61, the slider 63 and the second positioning block 62 are all rotatably arranged on the connecting rod 4, and the rotating surfaces of the first positioning block 61, the slider 63 and the second positioning block 62 are parallel to each other. The handle 151 and the connecting rod 152 are located on the same rotating surface, and the rotating surface is perpendicular to the rotating surfaces of the first positioning block 61, the slider 63 and the second positioning block 62. The rotating direction of the handle 151 is the axial direction of the connecting rod 4, thereby driving the slider 63 and the pistol drill 1 to move forward and backward along the connecting rod 4; the rotating direction of the first positioning block 61, the slider 63 and the second positioning block 62 is the radial direction of the connecting rod 4, so that the rotating rod 5 drives the pistol drill 1 to rotate around the connecting rod 4. The rotating rod is connected to the connecting rod 4 through the first positioning block 61, the slider 63 and the second positioning block 62, and can rotate relative to the connecting rod 4 to adjust the position of the pistol drill 1. Therefore, two groups of holes for the rotating rod 5 and the connecting rod 4 to pass through are opened on the first positioning block 61, the slider 63 and the second positioning block 62, and the axis center lines of the three holes in each group coincide. By rotating the rotating rod 5, the pistol drill 1 can be rotated within a certain range to adjust the drilling position.

[0032] like Figure 5 As shown, the slider 63 is provided with a first through hole 71 for the connecting rod 4 to pass through, a second through hole 72 for the rotating rod 5 to pass through, and a third through hole 73 for the pistol drill 1 to pass through. Bearings 8 are arranged in the first through hole 71 and the second through hole 72, and the slider 63 is also provided with an axle clamp 10 to fix the bearings 8 to prevent them from falling. The bearing 8 facilitates the rotation between the rotating rod 5 and the connecting rod 4 and the slider 63. A first plane is formed between the axis of the first through hole 71 and the axis of the second through hole 72, and a second plane is formed between the axis of the second through hole 72 and the axis of the third through hole 73, and the first plane intersects with the second plane. By controlling the angle between the first plane and the second plane, the drilling position of the pistol drill 1 can be adjusted.

[0033] An elastic member 18 is disposed between the second positioning block 62 and the slider 63, one end of the elastic member 18 acts on the second positioning block 62, and the other end of the elastic member 18 acts on the slider 63. When the handle 151 is pushed to drive the slider 63 and the pistol drill 1 forward for drilling, the slider 63 compresses the elastic member 18; after the drilling is completed, the slider 63 and the pistol drill 1 can automatically return to the initial position under the action of the restoring force of the elastic member 18. The elastic member 18 in this embodiment is a spring sleeved outside the rotating rod 5.

[0034] The limiting mechanism includes an arc groove 142 provided on the vertical plate and a limiting hook 141 provided corresponding to the arc groove 142. The limiting hook 141 is rotatably provided on the first vertical plate 31. The limiting hook 141 is rotatably provided on the vertical plate. The end of the rotating rod 5 passes through the arc groove 142. The limiting hook 141 is used to hook the end of the rotating rod 5 to fix the position of the rotating rod 5 in the arc groove 142. The opening direction of the arc groove 142 is the partial track of the rotating rod 5 rotating along the connecting rod 4. The position of the rotating rod 5 can be fixed by the limiting hook 141, and the position of the pistol drill 1 can be fixed. The limiting hook 141 in this embodiment is used to fix the rotating rod 5 at the upper end of the arc groove 142. At this time, the plane formed between the rotating rod 5 and the connecting rod 4 is parallel to the horizontal plane, that is, the first plane mentioned above is parallel to the horizontal plane.

[0035] In this embodiment, the rotating rod 5 can only be fixed at the top and bottom of the arc groove 142, that is, there are only two drilling positions. In other embodiments, a plurality of limit hooks 141 of different sizes can be provided to fix the rotating rod 5 at different positions, so that the drilling position of the pistol drill 1 has more selectivity.

[0036] In this embodiment, the rotation connection of the components is basically connected by bolt assembly 9 to realize the rotation between the two components, such as the rotation connection between the handle 151 and the connecting rod 152, the rotation connection between the lower end of the handle 151 and the first positioning block 61, the rotation connection between the lower end of the connecting rod 152 and the slider 63, and the rotation connection between the limit hook 141 and the vertical plate.

[0037] The working process of the drilling device in this embodiment is briefly described below:

[0038] The drilling device is placed on the truss 19 accordingly, with part of the truss 19 accommodated in the accommodation groove 172 , and the fastener 16 is tightened to fix the drilling device on the truss 19 through the hook portion 171 on the side of the accommodation groove 172 .

[0039] When the limit hook 141 does not hook the rotating rod 5, the end of the rotating rod 5 is located at the bottom of the arc groove 142. At this time, the first hole is drilled. When drilling, the upper end of the handle 151 is pushed to rotate toward the second vertical plate 32. Driven by the connecting rod 152, the slider 63 moves toward the second positioning block 62, and the slider 63 compresses the elastic member 18. The slider 63 drives the pistol drill 1 to move forward, and the pistol drill 1 is operated to start drilling. Figure 7 After the first hole is drilled, the upper portion of the handle 151 is pulled to rotate toward the first vertical plate 31. Under the action of the restoring force of the elastic member 18, the slider 63 moves toward the first positioning block 61, and the pistol drill 1 moves synchronously. Figure 6 shown.

[0040] The pistol drill 1 and the handle 151 are used to drive the rotating rod 5 to rotate, and the end of the rotating rod 5 moves to the top of the arc groove 142. The end of the rotating rod 5 is hooked by the limit hook 141 to fix the position of the rotating rod 5, thereby determining the position of the second drilling hole. The drilling operation of the second hole is then carried out. The specific process is the same as the drilling process of the first hole mentioned above, and will not be repeated here.

[0041] The drilling device of the present invention drives the connecting rod to move by rotating the handle, thereby pushing the slide block to slide, and the pistol drill connected to the slide block can move forward to drill or backward, and the operation is convenient and the drilling positioning is accurate.

[0042] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention.
