Technical Field

[0001] The utility model belongs to the technical field related to automobile steering, and particularly relates to a rapid deburring device for a pipe column. Background Art

[0002] A car's steering system is comprised of numerous components, including the steering gear and steering column. The steering column, also known as the steering column, is a crucial component of the vehicle's steering system. It connects the steering wheel to the steering gear, transmitting the driver's steering commands to the wheels and ensuring smooth steering. After production, the steering column may develop burrs at the tube end. To ensure workpiece accuracy, deburring is necessary. However, current deburring processes still suffer from the following drawbacks:

[0003] At present, the most common deburring operations on the market are performed by hand-held grinding machines, which is extremely time-consuming and labor-intensive. The grinding accuracy is insufficient and it relies entirely on manual experience. In addition, the burrs are generally located at the inner and outer edges of the pipe mouth, and flat grinding discs cannot meet the needs of grinding and deburring.

[0004] Secondly, a large amount of sparks will be generated during grinding, which can easily injure workers or affect the surrounding environment. Utility Model Content

[0029] See also Figure 1-6As shown, the utility model is a rapid deburring device for a tubular column, comprising a workbench 1, a motor 2, a main rod 3, a grinding ball head 4, a protective shell 5 and auxiliary grinding balls 7. The protective shell 5 is fixed at the center of the upper end surface of the workbench 1, a base 103 is fixed on the workbench 1 outside one end of the protective shell 5, and the upper end of the base 103 is fixed to the motor 2, a coupling 201 is fixed to the output shaft of the motor 2 and is transmission-connected to the main rod 3 through the coupling 201, a grinding ball head 4 is fixed to the end of the main rod 3 away from the coupling 201, and two auxiliary grinding balls 7 are symmetrically distributed outside the grinding ball head 4;

[0030] The workbench 1 is used as a mounting carrier for grinding and deburring. A motor 2 is installed above it through a base 103 so that the motor 2 has a certain height. The motor 2 drives the main rod 3 to rotate through the coupling 201, so that the grinding ball head 4 and the auxiliary grinding ball 7 rotate synchronously, thereby synchronously grinding the inner and outer edges of the port of the pipe column.

[0031] The outer spherical surface of the grinding ball head 4 is provided with symmetrically distributed and arc-shaped adjustment grooves 401, and a slider 403 is slidably provided in the adjustment groove 401. The end of the slider 403 away from the grinding ball head 4 is fixed to the auxiliary grinding ball 7 adjacent thereto;

[0032] The slider 403 slides in an arc shape in the adjustment slot 401, thereby causing the auxiliary grinding ball 7 to move in an arc path, thereby causing the auxiliary grinding ball 7 to move closer to or away from the end of the column barrel;

[0033] A collar 301 is sleeved on the outer periphery of the main rod 3, and two symmetrical connecting rods 3011 are hingedly connected to the outer periphery of the collar 301. The ends of the two connecting rods 3011 away from the collar 301 are hingedly connected to the two auxiliary grinding balls 7 respectively.

[0034] The setting of the collar 301 facilitates the adjustment of the position of the auxiliary grinding ball 7. The movable collar 301 moves toward the position of the grinding ball head 4, and the connecting rod 3011 is hingedly transmitted to the auxiliary grinding ball 7, causing it to move toward the outer edge of the port of the pipe column until it is tightly attached.

[0035] The four corners of the bottom of the workbench 1 are all fixed with supporting legs 101, and the bottom of all the supporting legs 101 is fixed with a bottom plate 102, and the bottom plate 102 has the same size as the workbench 1;

[0036] The workbench 1 is supported by legs 101 , and a base plate 102 is fixed at the bottom of the legs 101 to increase stability and provide the workbench 1 with a certain height.

[0037] A threaded section 303 is provided in the middle area of ​​the outer circumference of the main rod 3, and the collar 301 is located outside the threaded section 303. Threaded rings 302 are screwed onto the threaded sections 303 outside the ends of the collar 301.

[0038] The design of the threaded section 303 is mainly to facilitate the rotation of the threaded ring 302. The two threaded rings 302 are distributed at both ends of the collar 301, and can limit the position of the collar 301 after the collar 301 moves.

[0039] Both ends of the protective shell 5 are provided with openings 501, and the bottom end of the protective shell 5 below the opening 501 is also provided with a cleaning groove 502, which is connected to the opening 501; sparks and waste generated during grinding are blocked by the protective shell 5, and the waste is discharged from the cleaning groove 502 during subsequent cleaning.

[0040] A through slot 104 is formed in the workbench 1 at one end of the protective shell 5 away from the motor 2 , and two frames 6 in an inverted U-shaped structure and distributed in parallel are fixed to the upper end of the workbench 1 outside the through slot 104 .

[0041] Two horizontal plates 601 are fixed between the opposite surfaces of the two vertical arms of the frame 6. A screw 602 is threadedly connected to each horizontal plate 601. The opposite ends of the two screws 602 are rotatably connected to an arc-shaped clamping plate 603. The opposite ends of the two screws 602 are fixed with hand wheels 604.

[0042] The screw rods 602 are rotated by the hand wheel 604 to move the two screw rods 602 closer to each other until the tubing is locked, thereby completing the positioning of the tubing. The device is applicable to tubings of various radii.

[0043] An arc-shaped limit groove 402 is also provided in the grinding ball head 4 above and below the adjustment groove 401. Limiting balls 4031 are fixed at the upper and lower ends of the slider 403, and the limiting balls 4031 are slidably set in the limit groove 402 adjacent to it; the limiting balls 4031 on the upper and lower end surfaces of the slider 403 move in the limit groove 402, making it impossible for it to leave the limit groove 402, thereby ensuring the stable movement of the slider 403.

[0044] The specific working principle of the present invention is as follows: first, one end of the column is sleeved outside the grinding ball head 4, and the inner radius of the column cannot be larger than the radius of the grinding ball head 4. Then, ensure that the column is level, rotate the screw 602 by the hand wheel 604, so that the two screws 602 are close to each other until the column is locked, completing the positioning of the column. Then, rotate the two threaded rings 302 to move them away from each other, and at this time, the moving ring 301 is close to the grinding ball head 4. At this time, the auxiliary grinding ball 7 is close to the grinding ball head 4 through the transmission of the connecting rod 3011. 301, and the grinding ball 403 is rotated to move closer to the sleeve 301, and the sleeve 301 is locked. At this time, the motor 2 drives the main rod 3 to rotate through the coupling 201, so that the grinding ball head 4 and the auxiliary grinding ball 7 rotate synchronously, thereby synchronously grinding the inner and outer edges of the port of the pipe column to complete the deburring process.
