Description

Technical Field

[0001] The utility model relates to the technical field of surface grinders, in particular to a self-centering and aligning device for a rotary body. Background Art

[0002] A surface grinder is a type of grinding machine that primarily uses a grinding wheel to rotate and grind workpieces to achieve the required flatness. Based on the shape of the worktable, it can be divided into two types: rectangular and circular. When grinding ultra-high-hardness and high-hardness surfaces on the thrust surface of a rotating body, a surface grinder is required. The current market is diversified, and product requirements are constantly increasing. The hardness of the parts themselves is so high that it exceeds that of general tool steel. Consequently, the scrap rate during actual processing is extremely high, and the manufacturing efficiency itself is extremely low, making it impossible to meet actual mass production requirements.

[0003] Currently, when the rotating body is self-centering and aligned, it is necessary to manually adjust the product center height, manually align the V-block horizontally, and perform multiple back and forth corrections. This not only results in large manufacturing errors but also makes the operation complicated. Utility Model Content

[0007] Preferably, protrusions are provided on both sides of one end of the part body, and horizontal grooves matching the protrusions are provided on both sides of the inner side of the automatic alignment block, so that the same parallel planes of the same parts can be linked. When the two parts are on the same rotation center axis, the two parts will be automatically aligned horizontally or vertically.

[0008] Preferably, the two groups of alignment grooves are symmetrical to each other, so that the two groups of part bodies can be aligned at the same time.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3 The embodiment provided by the utility model: a self-centering and aligning device for a rotating body, comprising an auxiliary tool body 1, a part body 2 and an automatic aligning block 3. Alignment grooves 5 are provided on both sides of the inner side of the auxiliary tool body 1, and a V-shaped groove is provided in the middle of one side of the inner side of the aligning groove 5, which can quickly locate the central axis of the auxiliary tool. The two sets of aligning grooves 5 are symmetrical to each other, so that the two sets of part bodies 2 can be aligned at the same time.

[0018] Two sets of fixing bolts 6 are threadedly connected on both sides of the assistive tool body 1. Two sets of threaded holes connected to the alignment grooves 5 are respectively opened on both sides of the assistive tool body 1. Four sets of fixing bolts 6 are threadedly connected to the four sets of threaded holes. The fixing bolts 6 can be rotated to clamp the part body 2. Standard calibration blocks 4 are set on both sides of one end of the assistive tool body 1.

[0019] Bumps 7 are provided on both sides of one end of the part body 2, and horizontal grooves 8 that cooperate with the bumps 7 are opened on both sides of the inner side of the automatic alignment block 3, so that the same parallel planes of the same parts can be linked. When the two parts are on the same rotation center axis, the two parts will automatically align horizontally or vertically.

[0020] Working principle: After the device inserts the part body 2 into the alignment groove 5, the automatic alignment block 3 is inserted into one end of the part body 2. At this time, the protrusion 7 on the part body 2 can automatically snap into the horizontal groove 8, so that the two groups of part bodies 2 are kept at the same level. Then, the fixing bolt 6 is rotated to lock the two groups of part bodies 2. Under the guidance of the automatic alignment block 3, the two groups of part bodies 2 can be automatically positioned to the center axis of the auxiliary tool through the V-shaped groove inside the alignment groove 5, so that the center axis of the product component is completely parallel to the equipment plane, eliminating the axial diameter and cylindrical shape and position errors;

[0021] The standard calibration block 4 can be used to convert the height difference between the standard block and the actual product during grinding, and the tempering grinder can grind the product in place at one time;

[0022] Finally, the auxiliary tool is turned over. The auxiliary tool has a symmetrical structure. After grinding the A side, the auxiliary tool is turned over manually and ground directly according to the drop value previously converted by the standard block.
