Description

Technical Field

[0001] This utility model belongs to the field of railway locomotive parts maintenance technology, specifically relating to a conical horn tube correction fixture. Background Technology

[0002] The high and low frequency horns of railway locomotives serve as warning signals. During long-term locomotive operation, they are eroded by wind and sand, causing varying degrees of deformation and dents in the horn tubes, shortening their service life. Traditional correction methods involve manual operation, which is inefficient and difficult to guarantee accuracy. If steel pipe correction fixtures are used, they do not match the conical inner hole of the horn tube, and the steel pipes are prone to deformation after use, which cannot meet the requirements for horn tube deformation correction. Therefore, it is necessary to design a correction fixture for conical horn tubes to complete the horn tube deformation correction work. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to design a conical horn tube correction fixture to correct the deformation of the horn tube and the pit defects on the horn tube body, thereby extending its service life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a conical horn tube correction fixture, comprising a base, a turntable, a conical rod, a column, a clamping device, and a roller. The base surface is provided with a turntable and a column. A conical rod is vertically positioned at the center of the turntable. A conical horn tube to be corrected is fitted onto the conical rod. A column is provided on one side of the turntable. A clamping device that can move up and down is fitted onto the column. A roller is mounted on the clamping device. The roller and the conical rod cooperate to correct the conical horn tube.

[0005] The conical rod includes an upper frustum-shaped portion, a middle cylindrical portion, and a bottom mounting portion. The frustum-shaped portion is used to fit the conical horn tube to be corrected. The diameter of the top of the frustum-shaped portion is 25mm, the diameter of the bottom is 57mm, and its taper is 4°. The diameter of the cylindrical portion is 57mm. One end is connected to the frustum-shaped portion, and the other end is provided with a mounting portion. The mounting portion is provided with bolt mounting holes. The conical rod is mounted on the turntable by cooperating with the fixing bolts.

[0006] The turntable has an overall frustum-shaped structure. The turntable is located in the middle of the upper surface of the base and rotates by itself driven by a motor. The upper surface of the turntable is provided with a fixed seat, and the fixed seat fixes the conical rod to the turntable with fixing bolts.

[0007] The bottom of the column is fixed to one side of the base, and a clamping device is provided on the column body. The position of the clamping device on the column is adjusted by adjusting screws, and a roller is clamped at the end of the clamping device.

[0008] The roller is inclined, and the angle of inclination matches the taper of the upper part of the tapered rod.

[0009] The beneficial effects of this utility model are: the device has a simple structure, is easy to operate, and has strong versatility. It adopts a combination of rotation and roller pressing, which can uniformly correct the shape of the trumpet tube and avoid the problem of local overpressure or underpressure.

It should be noted that the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Please see Figure 1 , Figure 2A conical horn tube straightening fixture includes a base 1, a turntable 2, a conical rod 4, a column 5, a clamping device 6, and a roller 7. The base 1 has a turntable 2 and a column 5 on its surface. The conical rod 4 is vertically positioned at the center of the turntable 2. The conical horn tube to be straightened is fitted onto the conical rod 4. The column 5 is located on one side of the turntable 2. The clamping device 6, which can move up and down, is fitted onto the column 5. The roller 7 is clamped on the clamping device 6. The roller 7 cooperates with the conical rod 4 to straighten the conical horn tube. The conical rod 4 includes an upper frustum-shaped portion 401, a middle cylindrical portion 402, and a bottom mounting portion 403. The frustum-shaped portion 401 is used to fit the conical horn tube to be corrected. The diameter of the top of the frustum-shaped portion 401 is 25mm, the diameter of the bottom is 57mm, and its taper is 4°. The diameter of the cylindrical portion 402 is 57mm. One end is connected to the frustum-shaped portion 401, and the other end is provided with the mounting portion 403. The mounting portion 403 is provided with bolt mounting holes 404. The conical rod 4 is mounted on the turntable 2 by cooperating with the fixing bolts 9. The turntable 2 has an overall frustum-shaped structure. The turntable 2 is located in the middle of the upper surface of the base 1 and is driven by a motor to rotate. The upper surface of the turntable 2 is provided with a fixing seat 3. The fixing seat 3 fixes the conical rod 4 to the turntable 2 by fixing bolts 9. The bottom of the column 5 is fixed to one side of the base 1. A clamping device 6 is provided on the column body of the column 5. The position of the clamping device 6 on the column 5 is adjusted by adjusting screw 8. A roller 7 is clamped at the end of the clamping device 6. The roller 7 is inclined, and its inclination angle matches the taper of the upper part of the tapered rod 4.

[0015] During the use of this utility model:

[0016] First, the mounting part 403 at the bottom of the conical rod 4 is fixed to the fixed seat 3 of the turntable 2 using fixing bolts 9. Next, the horn to be corrected is fitted onto the frustoconical part 401 on the upper part of the conical rod 4. The inner diameter of the horn transitions from φ27mm to φ59mm, matching the taper of the frustoconical part 401 on the upper part of the conical rod 4, which increases from φ25mm to φ57mm. Then, the position of the clamping device 6 on the column 5 is adjusted so that the pressing surface of the roller 7 contacts the outer wall of the horn to be corrected. The motor is turned on to drive the turntable 2 to rotate. At this time, the conical rod 4, which is fixed to the fixed seat 3 by fixing bolts 9, also rotates. The horn to be corrected fitted on the conical rod 4 rotates and cooperates with the roller 7 that is in contact with it to correct the deformation and pit defects on the outer wall of the horn to be corrected.
