[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] The utility model provides a mounting structure for a honing oilstone, comprising a base 1. Figure 1 and Figure 2 As shown, the base 1 is cylindrical. A mounting groove is drilled in the axial direction of the base 1, and the mounting groove is a circular groove. The honing oilstone is inserted into the mounting groove. A disc-shaped support plate 6 is coaxially slidably assembled in the mounting groove along the axial direction of the base 1, and a limiting groove 7 matching the honing oilstone is cut on the support plate 6. A cover plate is assembled at the notch of the mounting groove, which covers the notch and is fixedly connected to the base 1. A through hole matching the honing oilstone is cut on the cover plate along the axial direction of the base 1, and the honing oilstone passes through the through hole on the cover plate and is plugged into the limiting groove 7. It is used for positioning the honing oilstone.

[0020] Two radially-cut I-shaped grooves are chiseled into the base 1. These grooves are opposite each other and communicate with the mounting recess. The mounting recess is located between the two I-shaped grooves. A matching I-shaped slider 4 is positioned within each I-shaped groove, allowing the two sliders 4 to slide toward or away from each other along their respective I-shaped grooves.

[0021] A circular plate 5 is coaxially connected to the base 1 and rotates coaxially. This plate 5 is machined with a flat thread, patterned after an Archimedean screw. The center of rotation of the flat thread is located at the center of the circular plate 5. Both sliders 4 are machined with flat thread segments. These flat threads and segments form a thread pair and engage with each other. Rotation of the circular plate 5 pushes the two sliders 4 toward or away from each other along their I-shaped slots.

[0022] The adjacent ends of the two sliding blocks 4 are welded with top blocks, and the two top blocks are in contact with the honing oil stone and are limitedly matched to clamp and fix the honing oil stone.

[0023] Two radially cut grooves 2 are cut into the base 1, each connected to the mounting groove. The two grooves 2 are opposite each other and correspond one-to-one with the two I-shaped grooves. Each groove 2 is connected to the corresponding I-shaped groove. Transmission components are installed within the two grooves 2. Two sliders 4, through the transmission components, interact with the support plate 6 to drive the support plate 6 along the mounting groove.

[0024] The transmission member includes two connecting rods 3, both hinged to the support plate 6. The two connecting rods 3 correspond one-to-one with the two sliders 4, with the end of each connecting rod 3 away from the support plate 6 hinged to the corresponding slider 4. The two connecting rods 3 correspond one-to-one with the two chute slots 2, with each connecting rod 3 located in the corresponding chute slot 2.

[0025] A limiter is installed between the circular plate 5 and the base 1. When the honing oilstone is clamped, the limiter is used to limit the rotation of the circular plate 5. Figure 3 As shown, the limiting member includes a block 9 and a slot. A clearance slot 8 is chiseled out in the circular plate 5, and the block 9 is slidably assembled in the clearance slot 8 and slides radially along the base 1. A spring 10 is placed in the clearance slot 8, and the spring 10 is arranged along the sliding direction of the block 9. One end of the spring 10 is fixedly connected to the block 9, and the other end is fixedly connected to the circular plate 5, for resetting and providing limiting force. A card joint is welded on the block 9, and the head position of the card joint is hemispherical. A card groove is chiseled out on the base 1, and the card groove matches the head of the card joint. The card joint and the card groove are contact-type plug-in limited cooperation.

[0026] Working Principle: During use, the honing oilstone is inserted into the mounting groove of the base 1 through the through-hole on the cover plate. Once the honing oilstone is inserted into the limiting groove 7 of the support plate 6, the circular plate 5 is rotated, which drives the flat thread to rotate. The flat thread, through the threaded segments of the threaded segments, pushes the two sliders 4 to slide closer along the I-shaped groove. The two sliders 4 push the two top blocks toward the honing oilstone until the two top blocks contact and clamp the honing oilstone. At this point, the honing oilstone is fixed and installation is complete, and the circular plate 5 stops rotating.

[0027] During the rotation of the circular plate 5, the circular plate 5 drives the clamping block 9 to rotate synchronously around the central axis of the base 1. The clamping joint on the clamping block 9 slides and abuts against the base 1 under the elastic force of the spring 10. When the honing oilstone is clamped and fixed and the circular plate 5 stops rotating, the head position of the clamping joint on the clamping block 9 abuts the clamping slot. The spring 10 extends and pushes the clamping block 9 to slide toward the clamping slot. The clamping block 9 drives the clamping joint into the clamping slot, and the head position of the clamping joint is inserted into the clamping slot to form a clamping fit.

[0028] As the two sliders 4 slide toward each other, the hinged ends of the two connecting rods 3 and their corresponding sliders 4 are pulled toward each other. Simultaneously, the two connecting rods 3 push the support plate 6 along the axial direction of the base 1, sliding toward the bottom of the mounting trough. When the honing stone is fully clamped and secured, the support plate 6 stops moving.

[0029] To unload the honing stone, rotate the circular plate 5 in the opposite direction. The circular plate 5, through its flat threads, pushes the two sliders 4 away from the honing stone. The two sliders 4 then drive the two top blocks away from the honing stone, releasing the stone from its clamping position. Simultaneously, the support plate 6 moves axially toward the cover plate along the base 1, pushing the honing stone out of the mounting groove. The stone can then be removed.

[0030] When the circular plate 5 rotates, the circular plate 5 drives the clamping block 9, and the clamping block 9 drives the clamping joint to slide out of the clamping groove, thereby releasing the limit of the circular plate 5. At this time, the spring 10 is compressed, and the clamping joint abuts against the base 1.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
