Technical Field

[0001] The utility model relates to the technical field of railway vehicle parts processing, in particular to an empty and loaded vehicle intermediate body drilling tool. Background Art

[0002] The automatic adjustment device for empty and loaded vehicles can automatically adjust the pressure of the brake cylinder within a certain range according to the change of vehicle load. The empty and loaded vehicle mechanism includes an intermediate body. When processing the intermediate body, a process is included to process the inclined hole on the intermediate body.

[0003] refer to Figure 4 、 5 , is the intermediate structure diagram, according to Figure 5 It can be seen from the cross-sectional view in the figure that the intermediate body includes an inclined hole. Since the inclined hole is drilled obliquely from the outer wall of the intermediate body, the intermediate body needs to be fixed in an inclined manner during drilling to complete the processing of the inclined hole. During the fixing process, the inclination angle of the intermediate body is difficult to control, and the inclined intermediate body is also difficult to fix, which leads to the processing technology of the inclined hole in the intermediate body being very complicated and the accuracy is not high.

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] refer to Figure 1 、 2The utility model proposes an empty and loaded vehicle intermediate drilling tool, including a base 1, a mounting plate 2 is installed on the base 1, the mounting plate 2 is tilted, and a workpiece 3 to be processed is mounted on the lower surface of the mounting plate 2 by bolts. The workpiece 3 is an intermediate body, and the surface of the workpiece 3 is arranged parallel to the mounting plate 2, that is, the workpiece 3 installed on the mounting plate 2 is also tilted, and its tilt angle is required to keep the position of the inclined hole 31 to be processed on the workpiece 3 vertical.

[0021] refer to Figure 3 The mounting plate 2 has a mounting hole 211, and the workpiece 3 is connected to the mounting hole 211 via a bolt. Specifically, the bolt is passed through the center hole of the workpiece 3 and is threadedly connected to the mounting hole 211. The mounting plate 2 also has a positioning hole 22, which corresponds to one of the connecting holes on the workpiece 3. A positioning pin is passed through the connecting hole and is threadedly connected to the positioning hole to limit the rotation of the workpiece 3 about the axial direction of the mounting hole 211.

[0022] The top edge of the mounting plate 2 is also provided with a mounting slot, into which an auxiliary plate 4 is bolted. The auxiliary plate 4 is arranged parallel to the base 1 and has a vertically positioned limit hole directly above and coaxially with the inclined hole 31. A drill sleeve 41 is installed in the limit hole. During machining, the drill bit needs to pass through the drill sleeve 41 before machining the workpiece 3. This limits the drill bit and prevents the drill bit from slipping and deviating when it contacts the inclined surface of the workpiece 3.

[0023] An avoidance hole 23 is also provided on the mounting plate 2, and the avoidance hole 23 is arranged between the limiting hole and the inclined hole 31, that is, the avoidance hole 23 is coaxially arranged with the limiting hole and the inclined hole 31. The drill bit passing through the drill sleeve 41 can pass through the avoidance hole 23 and then can contact the surface of the workpiece 3. By providing the avoidance hole 23, the mounting plate 2 can be prevented from affecting the feed of the drill bit.

[0024] A circular mounting portion 21 is also provided on the lower surface of the mounting plate 2. The mounting portion 21 mates with the circular protrusion on the workpiece 3, so that the circular protrusion on the workpiece 3 fits snugly within the mounting portion 21 during installation. A mounting hole 211 is provided within the mounting portion 21 and is coaxial with the mounting portion 21. This allows the mounting portion 21 to position the workpiece 3, allowing the workpiece 3 to be mounted on the mounting plate 2 more quickly and accurately.

[0025] The two sides of the base 1 are connected to the side panels 11 by bolts, and the inner surfaces of the two side panels 11 are provided with an oblique groove 111, that is, the two side panels 11 are provided with an oblique groove 111 on the side surface close to the base 1. The two oblique grooves 111 are arranged correspondingly, and the mounting plate 2 is inserted into the two oblique grooves 111 and fixed by bolts.

[0026] In summary, the present invention can achieve the purpose of tilting and supporting the workpiece 3 by cooperating with the base 1 and the mounting plate 2. After the workpiece 3 is tilted, the position of the inclined hole 31 to be processed thereon can be kept vertical. At this time, the workpiece 3 can be drilled using a drilling machine, and the processed hole position is the inclined hole 31. The processing and installation process is simple and convenient. Moreover, since the mounting plate 2 and the base 1 maintain a suitable tilt angle, the workpiece 3 only needs to be mounted on the mounting plate 2 to accurately position the processing posture of the workpiece 3. By installing the drill sleeve 41, the rotation process of the drill bit can be made more stable, thereby avoiding the problem of deviation when the drill bit contacts the tilted surface of the workpiece 3.
