Description

Technical Field

[0001] The utility model belongs to the technical field of brackets, and in particular relates to a drilling bracket. Background Art

[0002] In the drilling operation of wooden packaging boxes, the sizes of wooden packaging boxes are often uneven, and it is often necessary to drill holes on the outside of higher wooden packaging boxes. The current conventional construction method is that construction workers use handheld electric drills on scaffolding or stepladders to perform construction.

[0003] For example, the publication number CN 205086093 U2 proposes a drilling bracket, including a first base body for fixing an impact drill, a second base body supported on a workpiece, and an elastic connection device provided between the first base body and the second base body for connecting the first base body and the second base body, and the first base body and the second base body are respectively provided with through holes for the drill bit of the impact drill to pass through. The drilling bracket has a simple structure, and an elastic connection device is provided between the impact drill and the workpiece. After drilling, the impact drill can be automatically ejected from the drill hole by the elastic force of the elastic device, which reduces the labor intensity of workers and avoids quality damage to the drill hole surface.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned drilling bracket still has the following problems: when the above-mentioned bracket is performing drilling operations, flying debris can easily cause harm to the operator, and long-term operation can cause occupational diseases. At the same time, it is difficult for the above-mentioned bracket to drill wooden packaging boxes at higher places. At the same time, when drilling holes in the board, it is impossible to adjust the lateral or oblique angle, and it is impossible to meet the drilling requirements at different angles, which reduces the flexible operability of the drilling operation, thereby resulting in a certain degree of limitation in the practicability of the device. Therefore, improvements are now made to a drilling bracket. Utility Model Content

At the same time, the driving component and the drilling component can adjust the height during the drilling operation and avoid the injury of the operator caused by splashing debris, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model proposes a drilling bracket, comprising a base plate, a plurality of universal wheels are arranged at the bottom of the base plate, a sliding rod is fixedly connected to one end of the top of the base plate, a first screw is rotatably connected to the other end of the top of the base plate, a driving assembly is arranged on one side of the first screw, a first limit plate and a second limit plate are respectively sleeved on the outside of the sliding rod and the first screw, a mounting plate is installed between the first limit plate and the second limit plate, a movable plate is rotatably connected to one side of the top of the mounting plate, an adjusting assembly is arranged at the bottom of the mounting plate, and a drilling assembly is arranged on the top of the mounting plate;

[0007] The adjustment assembly includes a box body fixedly connected to the bottom of the mounting plate, a rack is installed inside the box body, a second motor is installed outside the box body, an output shaft of the second motor passes through one side of the box body and is sleeved with a gear on the outer surface, the gear meshes and rotates with the rack, limit blocks are installed on both sides of the rack, a limit rod is movable inside the limit block, the limit rod is fixed to the inner side of the box body, a piston rod is installed on the top of the rack, the piston rod passes through one side of the mounting plate and is rotatably connected to the movable plate.

[0008] Preferably, the drilling assembly includes a fixing frame fixedly mounted on the top of the movable plate, the fixing frame is internally rotatably connected to a second screw, the second screw passes through one side of the fixing frame and a third motor is installed, and the third motor drives the second screw to rotate, the external thread sleeve of the second screw is provided with a moving block, a limiting seat is installed on the top of the moving block, a connecting plate is provided on the top of the limiting seat, and a mounting frame for fixing is installed on the top of the connecting plate.

[0009] Preferably, the driving assembly includes a second bevel gear fixedly sleeved on the outside of the first screw, a first motor is installed on the top of the base plate, an output shaft of the first motor is fixedly connected to the first bevel gear, and the first bevel gear is meshed with the second bevel gear for transmission.

[0010] Preferably, a limiting hole is provided inside the limiting block, and the limiting rod is movably sleeved in the limiting hole.

[0011] Preferably, a limiting groove is provided on the top of the fixing frame, and the limiting seat is slidably connected to the limiting groove.

[0012] Preferably, a threaded hole is provided inside the first limiting plate, and the second limiting plate is threadably matched with the first screw rod.

[0013] The drilling bracket proposed by the utility model can bring the following beneficial effects:

[0014] 1. The output shaft of the first motor drives the first bevel gear to rotate counterclockwise or clockwise, so that the second bevel gear meshing with the first bevel gear drives the first screw to rotate synchronously, so that the second limit plate outside the first screw cooperates with the first screw to rise or fall. In this process, the second limit plate drives the connected mounting plate to move synchronously along the slide rod, and at this time drives the drilling machine fixed on the top of the mounting frame to move synchronously, so as to adjust the different heights of the drilling machine.

[0015] 2. The output shaft of the second motor drives the gear to rotate, and then the rack meshing with the gear drives the connected piston rod to move up and down inside the mounting plate. In this process, the movable plate on the top of the piston rod is pushed to move. When the movable plate overlaps with the mounting plate, the drilling machine fixed on the mounting frame drills horizontally. When the piston rod pushes the movable plate away from one side of the mounting plate, it drills obliquely, thereby adjusting different drilling directions.

[0016] 3. The output shaft of the third motor drives the second screw to rotate, so that the moving block outside the second screw moves along the top toward one end of the drilling hole. During the movement of the moving block, the limit seat on the top moves along the limit groove, so that the limit seat drives the connecting plate to move synchronously, thereby moving the mounting frame on the top of the connecting plate, and further making the drilling machine fixed on the top of the mounting frame contact with the drilling part outside the wooden box. No human participation is required in the drilling process, which greatly reduces the situation where debris splashes and injures the operator. BRIEF DESCRIPTION OF THE DRAWINGS

The mounting frame 19 is provided with a plurality of mounting holes inside, and drilling machines of different sizes can be installed, thereby increasing the flexibility of the bracket.

[0033] like Figure 1 As shown, the driving assembly includes a second bevel gear 7 fixedly sleeved on the outside of the first screw 4, a first motor 5 is installed on the top of the base plate 1, the output shaft of the first motor 5 is fixedly connected to the first bevel gear 6, and the first bevel gear 6 is meshed with the second bevel gear 7 for transmission.

[0037] Working principle:

[0038] When in use, the bracket can be moved by the universal wheel 2. If drilling is required, the external drilling machine can be fixed to the mounting bracket 19 on the bracket. When drilling is required at a high place, the external power supply is turned on and the first motor 5 is driven, so that the output shaft of the first motor 5 drives the first bevel gear 6 to rotate counterclockwise or clockwise, and then the second bevel gear 7 meshing with the first bevel gear 6 drives the first screw 4 to rotate synchronously, so that the second limit plate 26 outside the first screw 4 cooperates with the first screw 4 to rise or fall. In this process, the second limit plate 26 drives the connected mounting plate 8 to move synchronously along the slide bar 3, and at this time drives the drilling machine fixed on the top of the mounting bracket 19 to move synchronously until it is adjusted to a suitable height and stops the rotation of the first motor 5. When the drilling angle needs to be adjusted, the second motor 14 is driven, so that the output shaft of the second motor 14 drives the gear 17 to rotate, and then the rack meshing with the gear 17 16 drives the connected piston rod 12 to move up and down inside the mounting plate 8. During this process, the piston rod 12 pushes the top movable plate 10 to move. When the movable plate 10 overlaps with the mounting plate 8, the drilling machine fixed on the mounting frame 19 drills horizontally. When the piston rod 12 pushes the movable plate 10 away from the side of the mounting plate 8, it drills obliquely, thereby adjusting different drilling directions. After adjustment, the third motor 15 is driven to make the output shaft of the third motor 15 drive the second screw 21 to rotate, thereby making the moving block 22 outside the second screw 21 move along the top toward one end of the drilling hole. During the movement of the moving block 22, the top limit seat 23 moves along the limit groove 25, thereby making the limit seat 23 drive the connecting plate 24 to move synchronously, thereby moving the mounting frame 19 on the top of the connecting plate 24, and further making the drilling machine fixed on the top of the mounting frame 19 contact with the drilling part, thereby realizing drilling of different heights and angles.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
