Description

Technical Field

[0001] This utility model relates to the field of drilling auxiliary equipment, and in particular to a drilling and positioning device for side holes in sheet metal. Background Technology

[0002] Most furniture assembly currently involves mortise and tenon joints, especially furniture sold online. For ease of packaging and transportation, furniture is often packaged with mortise and tenon joints and then assembled by the buyer. Considering the ease of assembly between components, the mortise and tenon structure is mostly an assembly form of round holes with cylindrical wooden plugs. This involves panel assembly and strengthening connections, which requires drilling holes in the sides of the panels; especially for the installation of slides and tracks, drilling holes in the sides of the panels is inevitable.

[0003] When drilling holes on the side of a board, the hole should generally be centered on the side. Due to the mortise and tenon joint, the hole is deeper and requires a higher degree of verticality. In this case, unlike drilling on the flat surface of the board, directly drilling with a drill can easily result in misaligned holes and skewed holes. Currently, there is a lack of corresponding solutions to these problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a simple structure for a side hole drilling positioning device for sheet metal, which ensures that the hole is centered when drilling the sheet metal and helps to control the verticality of the hole.

[0005] The equipment includes a base, which is the basic assembly component of the equipment; The base is provided with a positioning through hole in the center; the positioning through hole is the channel through which the drill rod passes. Two guide rods, both round, are disposed beneath the base and positioned along any center line of the base. Here, the center line refers to any axis passing through the center point of the positioning through hole. The two guide rods are arranged symmetrically around the center of the positioning through hole. This symmetry refers to axisymmetry, where the axis is such that the line connecting the center points of the two guide rods passes through the center point of the positioning through hole.

[0006] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 3 As shown, when the two guide rods are respectively attached to the two sides of the plate, the positioning through hole is located in the center of the side of the plate; that is, the centering hole is achieved by drilling the hole in the side of the plate.

[0007] The beneficial effects of this utility model are that it solves the problems of inconvenience in manually drilling holes on the side of the board, which easily leads to misaligned holes and skewed holes in the existing technology. It achieves centered drilling with the drill rod, avoiding misaligned holes and skewed holes. In particular, the equipment has a simple structure, low cost, and greater market value.

Detailed Implementation

[0009] Reference Figure 1 , Figure 2 The present invention provides a plate side hole drilling and positioning device, which includes a base 1, and the base 1 is the assembly base of the device. The base 1 is provided with a positioning through hole 2 in the center; the positioning through hole 2 is the channel through which the drill rod passes. Two guide rods 3 are provided under the base 1. The two guide rods 3 are round rods, and their positions are located on any center line of the base 1. The center line here refers to any axis passing through the center point of the positioning through hole 2. The two guide rods 3 are arranged symmetrically about the center of the positioning through hole 2. The axis here refers to the line connecting the center points of the two guide rods 3 passing through the center point of the positioning through hole 2.

[0010] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 3 As shown, when the two guide rods 3 are respectively attached to the two sides of the plate, the positioning through hole 2 is located in the center of the side of the plate; that is, the centering hole is achieved by drilling on the side of the plate.

[0011] Example 1, refer to the accompanying drawings in the specification. Figure 1 The base 1 is an integrally formed rectangular plate with its four corners chamfered inwards.

[0012] The effect achieved in this way is that the device is easy to hold.

[0013] Furthermore, the base 1 is integrally formed and is made of plastic or wood.

[0014] Furthermore, refer to the accompanying drawings in the instruction manual. Figure 3 The base 1 is provided with a gripping crank 4 on its side.

[0015] The effect achieved in this way is that it is easy to push and operate, and during use, the control of holding the crank 4 ensures that the two guide rods 3 are constantly in contact with both sides of the plate.

[0016] In Example 2, a bearing is nested inside the positioning through hole 2.

[0017] This results in more durable equipment, and the bearing inner sleeve can rotate when it collides with the drill rod, avoiding damage from hard impacts.

[0018] Furthermore, the bearing is movably provided with constraint rings of various inner hole specifications.

[0019] Preferably, the constraint ring is nested inside the bearing.

[0020] The effect achieved in this way is to accommodate drill rods of different sizes. Preferably, the outer wall of the constraint ring is tightly fitted with the inner sleeve of the bearing, and its various specifications of inner holes correspond to drill bits of different sizes. The inner hole diameter and the drill bit are in a transition fit.

[0021] In Example 3, the guide rod 3 is rotatably mounted on the bottom surface of the base 1.

[0022] This makes it easier for the equipment to move along the sheet material.

[0023] Furthermore, the guide rod 3 is rotatably mounted on the bottom surface of the base 1 via a bearing, and the bearing is nested inside the base 1.

[0024] Furthermore, the guide rod 3 is a short metal rod with anti-slip texture on its outside.

[0025] This achieves the effect of making the equipment easy to push onto the sheet material while also providing an anti-slip effect.
