Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a ball head shell surface fixed-point grinding device. Background Art

[0002] The car ball head shell is an important component in the car suspension system, usually used to connect the steering knuckle and the steering rod to achieve the steering function of the wheel. It mainly consists of two parts: the ball shell and the ball head. The ball shell is a hollow spherical structure, while the ball head is a cylindrical structure with threads that can be connected to the steering rod.

[0003] The surface processing of the ball head shell is a process in which the surface of the ball head shell is processed into the required shape and precision by mechanical processing equipment. The processing precision of the ball head shell surface is very important for its performance. Therefore, during the processing, various parameters need to be strictly controlled to ensure that the processing precision meets the requirements.

[0004] As for the inner arc surface processing of the ball shell, if it is not completed in one step, when there are burrs and other defects caused by the processing and production process on the inner arc surface of the ball head shell that need to be removed, because the existing grinding method is to re-grind the internal arc surface with a grinding ball, this will result in too much ball head shell material being removed when removing burrs and other defects, causing dents if the processing technology is not precise, which will make the product scrapped. The difficulty of fixed-point processing is relatively high. Utility Model Content

[0026] It should be further explained that a power motor is provided inside the handheld board 101 , and the power motor can drive the rotating shaft 102 to rotate.

[0027] It is worth mentioning that when the power motor in the handheld board 101 is started, it can drive the rotating shaft 102 to rotate.

[0028] Furthermore, movable arc-shaped adjusting rods 111 are provided in the adjusting slide rails 112 on both sides, and an adjusting stop plate 109 is fixedly provided on the top of the arc-shaped adjusting rod 111 .

[0029] Furthermore, two arc-shaped arc-shaped clamping plates 105 are provided in the annular plate 108, and the arc-shaped clamping plates 105 on both sides are symmetrically positioned.

[0030] Furthermore, the arc-shaped clamping plate 105 is rotatably connected to a threaded shaft 107 at one end surface away from each other, and one end surface of the threaded shaft 107 extends outward and is threadedly connected to the inner wall of the annular plate 108 .

[0031] Furthermore, one end surface of the threaded shaft 107 on both sides extends outward and is fixedly connected to the rotating disk 106 .

[0032] Furthermore, a plurality of telescopic grooves 117 opening outward are provided on the spherical surface of the grinding ball head 114 close to the annular plate 108 , and the telescopic grooves 117 are arranged in a matrix.

[0033] Furthermore, a telescopic grinding block 113 that can be telescopically moved is disposed in the telescopic groove 117 , and the surface of the telescopic grinding block 113 is arc-shaped and has the same curvature as the surface of the grinding ball head 114 .

[0034] Furthermore, a plurality of retractable and movable pressing control panels 103 are provided on the other end surface of the grinding ball head 114 .

[0035] It should be further explained that a telescopic spring is provided in the inner part of the pressing control plate 103 and the telescopic grinding block 113 so that when the corresponding pressing control plate 103 is pressed inward, the corresponding telescopic grinding block 113 can move outward.

[0036] When using this solution, first move the ball head shell that needs to be processed on the inner spherical surface of the ball head shell to the working position, and place the ball head shell between the annular plate 108 and the polished ball head 114, and turn the inner arc surface of the ball head shell toward the polished ball head 114. At the same time, make the arc surface of the ball head shell contact and abut against the adjusting plates 109 at both ends. At this time, according to the position where the defects of the inner arc surface of the ball head shell need to be removed, adjust the telescopic moving angle of the arc adjusting rod 111 on both sides, and adjust the orientation angle of the inner arc surface of the ball head shell by moving the adjusting plates 109 on both sides, so that the position where the defects of the inner arc surface of the ball head shell need to be removed is aligned with the surface of the polished ball head 114.

[0037] At this time, manually rotate the rotating disk 106 on both sides, and the rotating disk 106 on both sides rotates and drives the threaded shaft 107 to rotate. At this time, the threaded shaft 107 rotates through the threaded connection with the annular plate 108, and then moves inward, while driving the arc-shaped clamping plates 105 on both sides to move closer to each other, and then the outer surface of the ball head shell is clamped through the annular plates 108 on both sides, so as to realize the positioning and determination of the position of the inner arc surface of the ball head shell where defects need to be removed.

[0038] When the defect is a smaller particle such as a burr that needs to be polished away, the annular plate 108 can be telescopically moved to drive the ball head shell close to the polishing ball head 114. At this time, after holding the handheld retaining ring 104 to play a fixed support effect, the handheld plate 101 is held and drives the rotating shaft 102 to rotate. At this time, the polishing ball head 114 is driven to rotate through the rotating shaft 102, and the burrs that need to be removed from the inner arc surface of the ball head shell are polished away through the top of the polishing ball head 114.

[0039] When the area of ​​defects on the inner arc surface of the ball head shell needs to be removed is large, the ball head shell is adjusted to the correct angle by adjusting the adjustment plates 109 on both sides, and the pressing control plate 103 at the corresponding position is pressed inward according to the grinding position. At this time, the pressing control plate 103 moves inward, and drives the telescopic grinding block 113 to move outward and protrude, and achieves the effect of prominent grinding. At this time, the hand-held plate 101 is held, and the power motor in the hand-held plate 101 is started, and the rotating shaft 102 is driven to rotate, thereby driving the grinding ball head 114 to rotate, and driving the telescopic grinding block 113 to rotate to achieve the grinding effect. After the annular plate 108 is controlled to be close to the grinding ball head 114, and the grinding effect is achieved, the grinding efficiency of the spherical surface inside the ball head shell is improved through the telescopic and adjustable telescopic grinding block 113.
