Description

Technical Field

[0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to a suspended tight seam drilling device. Background Art

[0002] With the rapid development of the manufacturing industry, especially in areas with increasing requirements for precision and efficiency, such as the railway vehicle manufacturing industry, drilling technology, as one of the key processing technologies, is of self-evident importance. Drilling equipment, as the core tool to achieve this goal, is a machine and equipment that processes cylindrical holes or holes on the target object by rotary cutting or rotary extrusion. It is widely used in manufacturing, construction, geological exploration and other fields. However, when dealing with large structural parts or structures with special material requirements, traditional drilling equipment is often limited by factors such as size, weight and working environment, and is difficult to apply directly. Especially in the railway vehicle manufacturing industry, such as aluminum alloy grain hopper cars, such as Figure 1 As shown, the vehicle body structure is complex, and some parts such as the roof panel need to be precisely processed after assembly to meet subsequent assembly requirements.

[0003] The roof plate drilling operation of the aluminum alloy grain hopper car is usually located at a higher position due to the large size of the roof plate and the fact that it has been assembled on the car body. The drilling position is usually located at a higher position, and there is a specific inclination angle between the drilling plane and the horizontal plane, which greatly increases the difficulty of the drilling operation. In addition, the roof plate is made of aluminum alloy. Although this material has the advantages of light weight and corrosion resistance, it is non-magnetic. Therefore, it is impossible to use magnetic drills and other drilling equipment that rely on magnetic adsorption for operation, which limits the application of automated drilling technology. For such difficult drilling operations, manual handheld electric drills are generally used. Although this method solves the problem that the equipment cannot be directly applied to a certain extent, it has many disadvantages: due to the high drilling position and the need for inclined operation, it is extremely inconvenient for workers to operate, and long-term operation can easily lead to physical fatigue and increase safety hazards; manual drilling is difficult to ensure the accuracy and consistency of the hole position, affecting product quality; manual operation is inefficient and difficult to meet the needs of mass production, increasing production costs.

[0035] Embodiment 1

[0036] See attached Figures 2 to 11. A suspended tight seam drilling device comprises a mounting seat 1, a sliding mechanism 2, a swinging mechanism 3 and a tight seam drilling mechanism 4; the mounting seat 1, the sliding mechanism 2, the swinging mechanism 3 and the tight seam drilling mechanism 4 are sequentially connected from top to bottom; the sliding mechanism 2 is used to adjust the positions of the swinging mechanism 3 and the tight seam drilling mechanism 4 relative to the roof panel; the swinging mechanism 3 is used to adjust the angle between the tight seam drilling mechanism 4 and the roof panel; the tight seam drilling mechanism 4 is used to press the roof panel and the vehicle side beam, and then drill holes in the roof panel. It can be seen from the above structure that the suspended tight seam drilling device of the present invention comprises a mounting seat 1, a sliding mechanism 2, a swinging mechanism 3 and a tight seam drilling mechanism 4, such as Figure 3 As shown, the mounting seat 1, the sliding mechanism 2, the swing mechanism 3 and the tight seam drilling mechanism 4 are connected in sequence from top to bottom. The mounting seat 1 is used to connect with the vehicle body assembly tire frame 8. When the suspended tight seam drilling device is working, the entire device is fixed on the vehicle body assembly tire frame 8 through the mounting seat 1, and then the top plate of the aluminum alloy grain hopper car is drilled. Figure 2 As shown. A sliding mechanism 2 is connected to the bottom of the mounting seat 1, a swing mechanism 3 is connected to the bottom of the sliding mechanism 2, and a tight seam drilling mechanism 4 is connected to the bottom of the swing mechanism 3. The tight seam drilling mechanism 4 is used to press the roof panel and the vehicle side beam and drill holes on the roof panel; the two sides of the roof panel are arc-shaped, and the angle between the tight seam drilling mechanism 4 and the roof panel can be adjusted by the swing mechanism 3, so that the tight seam drilling mechanism 4 is perpendicular to the working surface of the drilling; after adjusting the angle of the swing mechanism 3, since the swing mechanism 3 and the tight seam drilling mechanism 4 can move along the length direction of the aluminum alloy grain hopper car through the sliding mechanism 2, the positions of the swing mechanism 3 and the tight seam drilling mechanism 4 relative to the aluminum alloy grain hopper car can be adjusted by the sliding mechanism 2, so that the swing mechanism 3 and the tight seam drilling mechanism 4 are moved to the position where the aluminum alloy grain hopper car roof panel needs to be drilled. The suspended tight-seam drilling device of the present invention realizes the pressing and drilling operations between the roof panel and the side beam of the aluminum alloy grain hopper car, and is also suitable for the pressing and drilling operations between the larger-sized roof panel and the side beam assembled on the vehicle body. The position and angle of the tight-seam drilling device relative to the aluminum alloy grain hopper car can be easily and quickly adjusted through the sliding mechanism 2 and the swinging mechanism 3, which solves the problem of high labor intensity and inconvenient operation when manual drilling is used for long and large processed parts, and ensures the accuracy and consistency of drilling, thereby improving work efficiency.

[0038] See attached Figures 3 to 11On the basis of the first embodiment, the sliding mechanism 2 includes a slide rail 21, a slider 22 and a locking assembly 23; the bottom of the mounting seat 1 is connected to the slide rail 21; a sliding slider 22 is provided inside the slide rail 21; the slider 22 is connected to the first connecting seat 5; a locking assembly 23 is provided between the first connecting seat 5 and the slide rail 21; the locking assembly 23 is used to lock the slider 22 on the slide rail 21. As can be seen from the above structure, the sliding mechanism 2 includes a slide rail 21, a slider 22 and a locking assembly 23, as shown in FIG. Figure 4 and Figure 5 As shown, when the mounting seat 1 is mounted on the tire frame 8 of the vehicle body assembly, the slide rail 21 is arranged along the length direction of the aluminum alloy grain hopper car, wherein the slide rail 21 can be composed of two I-shaped steels, and the I-shaped steel groove is the slide rail 21. A slidable slider 22 is provided in the slide rail 21. The slider 22 can be cylindrical, so as to reduce friction and facilitate the sliding of the slider 22 in the slide rail 21. A first connecting seat 5 is connected to the slider 22. When the slider 22 slides, the first connecting seat 5 moves synchronously with the slider 22. A locking assembly 23 is provided between the first connecting seat 5 and the slide rail 21. After adjusting the position of the slider 22 on the slide rail 21, the slider 22 can be locked on the slide rail 21 through the locking assembly 23, and the first connecting seat 5 is also locked at the same time.

[0039] The locking assembly 23 includes a self-locking air cylinder 231; the bottom of the self-locking air cylinder 231 is fixed on the first connecting seat 5, and the output end faces the outer side of the bottom of the slide rail 21; the piston rod of the self-locking air cylinder 231 is telescoped between the output end face and the outer side of the bottom of the slide rail 21, and is used for locking and unlocking the slider 22 and the slide rail 21.

After adjusting the position of the slider 22 on the slide rail 21, the self-locking air cylinder 231 is started, and the piston rod of the self-locking air cylinder 231 is extended until it is against the outer side surface of the bottom of the slide rail 21. In this way, a clamping force is formed between the slider 22 and the piston rod on the outer side surface of the bottom of the slide rail 21, thereby locking the slider 22 on the slide rail 21; when it is necessary to slide the slider 22 on the slide rail 21, the self-locking air cylinder 231 is started to retract the piston rod of the self-locking air cylinder 231, thereby unlocking the slider 22 from being locked on the slide rail 21. By setting the locking assembly 23, the slider 22 and the first connecting seat 5 are locked in a normal state to prevent them from moving under external force, which has high safety. When adjustment is required, unlocking is performed.

[0040] The piston rod of the self-locking air cylinder 231 is provided with a buffering pad 232. As can be seen from the above structure, when the piston rod of the self-locking air cylinder 231 is extended and contacts the outer side of the bottom of the slide rail 21, the buffering pad 232 plays a certain buffering role to protect the slide rail 21.
