Description

Technical Field

[0001] The utility model relates to the technical field of end plate drilling, in particular to a tool for quickly drilling inclined holes in an end plate. Background Art

[0002] Segment end plates are crucial structural components used to connect steel segments. During tunnel construction, particularly during shield or pipe jacking construction, steel segments serve as a primary component of the tunnel lining. To ensure reliable connections between segments, holes are drilled in the end plates. These holes are used to insert fasteners such as bolts or pins, securing adjacent segments tightly together.

[0003] Based on specific engineering requirements or to improve the strength and stability of structural connections, it is sometimes necessary to drill inclined holes at specific angles on the end plates. However, angle drilling is somewhat difficult because it requires precise positioning and control to ensure that the drill bit enters the material at a predetermined angle and remains stable. In addition, ordinary drilling machines are difficult to complete angle drilling tasks. Usually, drilling machines, boring machines or CNC machine tools with tilting functions are required. The procurement costs of these equipment are high, especially when there is only a batch of production needs, the return on investment is low. In addition, angle drilling also needs to solve the chip removal problem. When drilling vertically, the cut chips can fall down naturally, but when drilling at an angle, the chips are easily blocked in the hole, affecting the drilling quality and efficiency.

[0009] As a further improvement, the support seat is used to support the end plate, and an inclined block is fixedly installed at the drilling point of the end plate.

[0010] As a further improvement, the inclined surface of the inclined block is arranged coplanar with the end plate, and the top surface of the inclined block is in a horizontal state when the end plate is supported.

Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Working principle: According to the inclination angle of the end plate 4 to be processed, it is placed on several supporting seats 1 that match it, and the distance and parallelism between the supporting seats 1 are adjusted according to the length of the end plate 4. At this time, the end plate 4 is placed at an angle, and the top surface of the inclined block 5 is in a horizontal state. Use a drilling machine to drill vertically to the positioning point on the top surface of the inclined block 5 to obtain an inclined hole.

[0023] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.

[0024] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0025] Example 1 of a tool for quickly drilling inclined holes in end plates provided by the present invention:

[0026] like Figure 1-2 As shown, a tool for quickly drilling inclined holes in end plates includes several support seats 1. The support seat 1 is a triangular seat, and the support surface 2 of the support seat 1 is inclined. The lower end of the support surface 2 is fixedly connected with a stopper 3 for positioning the end plate 4. The stopper 3 and the support surface 2 are vertically arranged. The end plate 4 is supported by the support seat 1 and is located on the support surface 2. The design of the stopper 3 is conducive to fixing the end plate 4 to prevent the end plate 4 from slipping off the support seat 1.

[0027] The support seat 1 can be directly cut according to the angle of the inclined hole required for processing the end plate 4, wherein the angle between the support surface 2 and the horizontal plane is complementary to the angle of the required inclined hole. In this embodiment, the support seat 1 and the block 3 are cut into one piece using 30mm thick steel plates. This design method is simple and relatively low in cost. The matching support seat 1 can be designed and processed immediately according to different processing requirements.

[0028] like Figure 1-2As shown, the support seat 1 is used to support the end plate 4, and an inclined block 5 is welded at the drilling point required for the end plate 4, wherein the inclined surface of the inclined block 5 is coplanar with the upper surface of the end plate 4, and the top surface of the inclined block 5 is in a horizontal state when the end plate 4 is supported by the support seat 1. When drilling, the end plate 4 is placed on several support seats 1, and the distance and parallelism between the support seats 1 are adjusted according to the length of the end plate 4. Then, according to the positioning dimension line of the top surface of the inclined block 5, the purpose of drilling inclined holes in the end plate 4 can be achieved by vertically drilling with a drilling machine. Vertical drilling is conducive to the smooth discharge of chippings, reducing drilling quality problems caused by chip blockage; the setting of the inclined block 5 can ensure the convenience and stability of drilling, and at the same time, when the end plate 4 is assembled with the external mechanism, it can ensure that the end face of the external nut is parallel to the top surface of the inclined block 5, thereby increasing the tightening force of the bolt connection.

[0029] Example 2 of a tool for quickly drilling inclined holes in end plates provided by the present invention:

[0030] The main difference between it and Example 1 is:

[0031] like Figure 3 As shown, the stopper 3 is L-shaped, and a rectangular groove is formed between the inner side of the stopper 3 and the support surface 2. This design allows the end plate 4 to be directly inserted into the rectangular groove, fixing the end plate 4 from two directions, increasing the stability of the end plate 4, and preventing the end plate 4 from deflecting or vibrating during the drilling process.

[0032] While the above-described ideal embodiments of the present invention serve as a guide, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art will appreciate numerous modifications, variations, and alternatives without departing from the concept and spirit of the present invention. It should be understood that in practicing the present invention, various alternatives to the embodiments of the present invention described herein may be employed. The appended claims are intended to define the scope of the present invention and, therefore, cover modular components, equivalents, or alternatives within the scope of these claims.
