Description

Technical Field

[0001] This utility model relates to the field of wooden door production technology, specifically a paint hole drilling device. Background Technology

[0002] Wooden doors are now mostly used as interior doors. During the production of wooden doors, they need to be painted. After the paint is applied to the wooden door, before it has solidified, paint holes are usually made at both ends of the wooden door. Then, columnar objects are inserted into the holes to support the wooden door, reduce the contact between the wooden door and other objects, and minimize damage to the paint. Some wooden doors are pre-drilled with holes for installing locks when they leave the factory. Most existing hole-drilling equipment uses fixed-size molds to drill into the inside of the wooden door. However, most existing hole-drilling molds are of fixed size and it is difficult to adjust the size. If the hole size is different from the mold size, the hole needs to be manually adjusted again, which is quite inconvenient. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a paint hole drilling device includes:

[0024] The system includes a support plate 100, a rotating mechanism 200 that can adjust the reciprocating rotation of the drilling mechanism 400, two moving mechanisms 300 that can adjust the height of the support plate 100, and a drilling mechanism 400 that can drill holes of different diameters. The top surface of the support plate 100 has a sleeve hole, and the rotating mechanism 200 is rotatably sleeved inside the sleeve hole. The two moving mechanisms 300 are slidably engaged with both ends of the support plate 100, respectively. The drilling mechanism 400 is fixedly connected to the rotating mechanism 200. The drilling mechanism 400 includes a retaining rail 410, and two retaining rings are slidably engaged inside the retaining rail 410. A rotating rod 420 is rotatably sleeved inside each retaining ring. A connector 421 is fixedly connected to the bottom end of each rotating rod 420. A spiral milling cutter 422 can be detachably connected inside each connector 421.

[0025] Specifically, by placing the area of ​​the wooden door to be drilled under the support plate 100, and then installing spiral cutters 422 inside the two connectors 421, rotating the two rotating rods 420 drives the two spiral cutters 422 to rotate synchronously. Simultaneously, the moving mechanism 300 lowers the support plate 100, allowing the two spiral cutters 422 to drill into the interior of the wooden door. Then, the rotating mechanism 200 drives the two spiral cutters 422 to rotate reciprocally, causing them to move in a circular motion. This creates a suitable annular groove on the wooden door. Finally, by moving the two spiral cutters in opposite directions... Two spiral cutters 422 mill the wood inside the annular groove on the wooden door until the gap between the two spiral cutters 422 is minimal, leaving only thin rod-shaped pieces of wood remaining inside the annular groove. Then, the support plate 100 is moved upward to detach the spiral cutters 422 from the wooden door, and the remaining wood inside the annular groove is broken off and removed, forming a hole in the original annular groove on the wooden door. The size of the hole can be adjusted by adjusting the distance between the two spiral cutters 422, and the thickness of the hole can be adjusted by moving the height of the support plate 100, making it convenient for users.

[0026] Example 1

[0027] like Figure 1-4 As shown, in this embodiment, a drive box 430 is provided above each rotating rod 420, and a connecting plate 431 with a U-shaped cross-section is fixedly connected to the bottom end of each drive box 430. A drive motor is provided inside each drive box 430, and the top end of each rotating rod 420 passes through the adjacent connecting plate 431. A helical gear 401 is fixedly sleeved between the motor shaft of each drive motor and the top end of each rotating rod 420. Two helical gears 401 on the same connecting plate 431 mesh with each other, and one side of the retaining rail 410 is fixed. A guide rail 440 is connected, and two guide rods 441 are slidably engaged inside the guide rail 440. The two guide rods 441 are fixedly connected to two connecting plates 431 respectively. A positive and negative threaded screw is rotatably connected between the two ends inside the guide rail 440. Each of the two guide rods 441 has a screw hole at one end, and both screw holes are screwed into the positive and negative threaded screw. A power box 442 is fixedly connected to one end of the guide rail 440, and a power motor is installed inside the power box 442. The motor shaft of the power motor is fixedly connected to one end of the positive and negative threaded screw.

[0028] In this embodiment, by starting two drive motors, the two rotating rods 420 can be driven to rotate synchronously through the transmission of the helical gear 401. The two drive boxes 430 are located on opposite sides of the two rotating rods 420, so that the two rotating rods 420 can move closer together when they move towards each other. The two connecting plates 431 can be supported and positioned by the two guide rods 441. Starting the power motor to drive the positive and negative thread screws to rotate can drive the two guide rods 441 to move towards or away from each other, thereby driving the two rotating rods 420 to move towards or away from each other through the two guide rods 441.

[0029] like Figure 1-3 As shown, in this embodiment, the rotating mechanism 200 includes:

[0030] The rotating plate 210, the gear ring 220, and the motor box 230 are arranged in a manner such that the outer wall of the rotating plate 210 is rotatably fitted into the sleeve hole on the support plate 100, the center of the top surface of the rotating plate 210 has a connecting groove, and both rotating rods 420 are located inside the connecting groove. The gear ring 220 is fixedly fitted onto the top surface of the rotating plate 210. The motor box 230 is fixedly connected to the top surface of the support plate 100 by a support rod. A stepper motor is installed inside the motor box 230, and the motor shaft of the stepper motor is fixedly fitted with a drive gear 231, which meshes with the gear ring 220.

[0031] In practice, by starting the stepper motor, the rotating plate 210 can be driven to reciprocate through the drive gear 231 and the gear ring 220, thereby causing the rotating plate 210 to drive the two rotating rods 420 to reciprocate in a circular motion, so that the two spiral milling cutters 422 can perform milling operations on the wooden door.

[0032] like Figure 3 As shown, in this embodiment, the moving mechanism 300 includes:

[0033] Two slide rails 310 and two cylinders 320 are provided. The two slide rails 310 are located at both ends of the support plate 100. Sliders are fixedly connected to both ends of the support plate 100, and the two sliders are slidably engaged inside the two slide rails 310. The two cylinders 320 are fixedly connected to the top of the two slide rails 310, and the movable ends of the two cylinders 320 are fixedly connected to the two sliders.

[0034] In practice, the two cylinders 320 can be activated to move the pallet 100, thereby adjusting the height of the pallet 100 and simultaneously adjusting the milling depth of the two spiral milling cutters 422, making it convenient for users to operate.

[0035] Example 2

[0036] Based on Embodiment 1, the clamping rod 330 is provided to facilitate the fixing of the two slide rails 310 to the wooden door.

[0037] like Figure 3 As shown, in this embodiment, a rectangular hole is provided at the bottom of one side of any slide rail 310, a clamping rod 330 is slidably sleeved inside any rectangular hole, a clamping plate is fixedly connected to one end of any clamping rod 330, and a threaded hole is provided at the bottom of any slide rail 310.

[0038] In practice, when it is necessary to make holes in the wooden door panel, the bottom ends of the two slide rails 310 can be placed directly on the wooden door panel so that the two slide rails 310 and the support plate 100 are naturally fixed by their own weight. Alternatively, the two slide rails 310 can be fixed by manually pressing the support plate 100. When it is necessary to make paint holes at the edge of the wooden door, the two clamping rods 330 can be slid into the two rectangular holes so that the two clamping plates hold the two panels of the wooden door. The threaded holes are connected to the interior of the adjacent rectangular holes. Then, screws are screwed into the threaded holes so that the screws abut against the clamping rods 330 to fix the position of the clamping rods 330, thereby facilitating the two spiral milling cutters 422 to make holes at the edge of the wooden door.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
