Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a flange drilling device for manufacturing automotive wheel hubs. Background Technology

[0002] In the manufacturing of automobile wheel hubs, flange fittings are often used. Flanges are important parts commonly used in modern mechanical industry. They are mainly used for the connection between two pieces of equipment. In order to facilitate the connection, several through holes for connection are usually opened around the perimeter of the disc-shaped metal body during the production and processing of flanges.

[0003] Utility model patent CN222696566U discloses a flange drilling device, including a main body with a rotatable worktable. Above the worktable is a drilling device for drilling flanges. The worktable has an outer ring clamping assembly for clamping the outer ring of the flange and an inner ring clamping assembly for clamping the inner ring. A platform for placing the flange protrudes from the worktable. The inner ring clamping assembly and the platform are concentrically arranged, and the radius of the platform is smaller than the radius from the center of the flange to the drilling position. The main purpose of this utility model is to provide a flange drilling device with a reasonable and ingenious design, stable and reliable clamping, and convenient drilling operation.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: when clamping the flange, the device needs to use two drive mechanisms to work synchronously with the lead screw to achieve clamping and fixing of the flange. However, the setting of two drive mechanisms will make the equipment control system complicated, and the debris generated during drilling is easy to fall into the surface of the lead screw, affecting the normal operation of the lead screw. Therefore, we propose a flange drilling device for automobile wheel hub manufacturing. Summary of the Invention

Collection frame. Detailed Implementation

[0022] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] Please see Figure 1-4 A flange drilling device for manufacturing automobile wheel hubs includes a base 1, a clamping mechanism 2 and a drilling mechanism 3 on the top of the base 1, and a collection frame 4 slidably connected to the top of the base 1.

[0024] The clamping mechanism 2 includes a vertical plate 201, which is fixed to the top of the base 1. A mounting plate 202 is fixed to the left side surface of the vertical plate 201. Three U-shaped frames 203 are fixed to the surface of the mounting plate 202. A support frame 204 is fixed to the right side surface of the vertical plate 201. A clamping cylinder 205 is fixed to the surface of the support frame 204. One end of the clamping cylinder 205 passes through the support frame 204 and is fixed with a push rod 206. The push rod 206 slides through the vertical plate 201 and the mounting plate 202. Three connecting plates 208 are hinged to the left side surface of the mounting plate 202. A movable plate 207 is hinged to the surface of the connecting plates 208. The movable plate 207 is hinged to the U-shaped frames 203. An arc-shaped clamping plate 209 is fixed to the surface of the movable plate 207. A placement rack 210 is fixed to the left side surface of the vertical plate 201.

[0025] With the above technical solution, when drilling is required on the flange, the flange is first placed on the placement frame 210. At this time, the clamping cylinder 205 is activated, and one end of it drives the push rod 206 to move. After the push rod 206 passes through the support frame 204 and the upright plate 201, under the action of the connecting plate 208 hinged to the left surface of the mounting plate 202, it drives the movable plate 207 hinged to it to perform corresponding actions, thereby causing the arc-shaped clamping plate 209 on the movable plate 207 to clamp and fix the flange. The entire clamping process can be completed by a single clamping cylinder 205, without the need for multiple drive mechanisms to cooperate with the lead screw to run synchronously. This greatly simplifies the control system of the equipment, reduces the possible failure points caused by the cooperation of multiple drive mechanisms, reduces the maintenance cost and complexity of the equipment, and avoids the situation where debris enters during the operation of the lead screw and affects normal operation. This improves the reliability and stability of the equipment, provides a solid foundation for subsequent drilling operations, and ensures drilling accuracy and quality.

[0026] The drilling mechanism 3 includes a lifting block 301, a mounting shell 302 fixed to the top of the lifting block 301, a pushing cylinder 303 fixed to the left side surface of the mounting shell 302, one end of the pushing cylinder 303 passing through the mounting shell 302 and fixed to a moving plate 304, a first motor 305 fixed to the left side surface of the moving plate 304, the output shaft of the first motor 305 passing through the moving plate 304 and fixed to a horizontal plate 306, a second motor 307 fixed to the surface of the horizontal plate 306, and a drilling head 308 fixed to the output shaft of the second motor 307.

[0027] With the above technical solution, when drilling is required, the cylinder 303 is started, which drives the movable plate 304 fixed to it to move within the mounting housing 302. At the same time, the first motor 305 runs, and its output shaft drives the horizontal plate 306 to rotate. The second motor 307 is fixed on the horizontal plate 306, and its output shaft drives the drill head 308 to rotate at high speed, thereby realizing the precise drilling operation of the flange.

[0028] The movable plate 304 is slidably connected to the inner wall of the mounting shell 302, and a slag discharge groove 309 is provided on the right side surface of the mounting shell 302.

[0029] Through the above technical solution, when the moving plate 304 is driven by the pushing cylinder 303, it can move stably in a straight line inside the mounting shell 302, thereby driving the drill head 308 to accurately approach or move away from the drilling position of the flange. The slag discharge groove 309 opened on the right side surface of the mounting shell 302 can facilitate the discharge of generated debris outside the equipment during the drilling process, avoiding the accumulation of debris inside the equipment, which would affect the normal drilling process and the cleanliness of the equipment.

[0030] A circular slide rail 310 is fixed on the right side surface of the movable plate 304. Two sliders 311 are slidably connected to the surface of the circular slide rail 310. The surface of the sliders 311 is fixedly connected to the surface of the horizontal plate 306.

[0031] With the above technical solution, when the first motor 305 drives the horizontal plate 306 to rotate, the slider 311 slides on the circular slide rail 310 accordingly, thereby guiding the horizontal plate 306 and the second motor 307 and the drill head 308 on it to perform stable rotational motion, so that the drill head 308 can drill holes in the flange at a suitable angle and position.

[0032] The push rod 206 is located on the right side of the upright plate 201 and a mounting block 211 is fixed thereon. A spring 212 is fixed on the left side of the mounting block 211 and the left end of the spring 212 is fixedly connected to the right side of the upright plate 201.

[0033] Through the above technical solution, when the clamping cylinder 205 drives the push rod 206 to perform clamping or releasing actions, the spring 212 can play a role in buffering and resetting. When the push rod 206 is subjected to external force or undergoes a certain displacement during its own movement, the elastic deformation of the spring 212 can absorb some energy, reduce the impact of the push rod 206, and at the same time provide a certain rebound force when needed to assist the push rod 206 in returning to its initial position, thereby ensuring the stable operation of the clamping mechanism 2 and the reliability of clamping.

[0034] Collection box 4 is located directly below the placement rack 210 and to the right of the lifting block 301.

[0035] With the above technical solution, when the drill bit 308 drills a hole in the flange placed on the mounting frame 210, the debris will naturally fall downwards under the influence of gravity, and the collection frame 4 is located on the path of these falling debris, thereby achieving effective collection of debris.

[0036] The first motor 305 is a servo motor with a brake device installed at the tail.

[0037] Through the above technical solution, during the drilling process, the servo motor can accurately control the speed and rotation angle of the drill head 308 to achieve precise drilling operation; when drilling is paused or finished, the brake device can quickly brake the motor, so that the drill head 308 stops rotating immediately, avoiding drilling position deviation caused by the motor's inertia continuing to rotate.

[0038] The surface of the arc-shaped clamp 209 is provided with an anti-slip and wear-resistant coating.

[0039] Through the above technical solutions, the anti-slip and wear-resistant coating can further increase the friction of the arc-shaped clamp 209, improve the clamping effect on the flange, and extend the service life of the arc-shaped clamp 209.

[0040] Working Principle: First, the flange is placed on the placement rack 210. The clamping cylinder 205 in the clamping mechanism 2 is activated, and the push rod 206 moves under the drive of the cylinder. Through the linkage of the connecting plate 208 and the movable plate 207, the arc-shaped clamping plate 209 stably clamps the flange. At the same time, the pushing cylinder 303 in the drilling mechanism 3 starts working, driving the moving plate 304 to move within the mounting shell 302. The first motor 305 runs, and its output shaft drives the horizontal plate 306 to rotate. The second motor 307 is fixed on the horizontal plate 306 and drives the drill head 308 to rotate at high speed, thereby precisely drilling the clamped flange. During the drilling process, the generated debris is effectively collected and cleaned through the slag discharge trough 309 and the collection frame 4. The entire equipment operates smoothly, and the various components work closely together, achieving efficient and precise drilling of the flange.
