Description

Technical Field

[0001] The utility model relates to the field of honing equipment, and specifically provides a guiding device for honing equipment and the honing equipment. Background Art

[0002] Honing is a method of finishing holes using a honing head with a grinding bar (oil stone). During the honing process, the workpiece is fixed, and the honing head is driven by the machine tool spindle to rotate and reciprocate in a straight line. At the same time, the grinding bar acts on the workpiece surface with a certain pressure, cutting off a very thin layer of material from the workpiece surface. The cutting track left on the hole wall is usually a cross-net pattern. Among them, the main body of the honing equipment and the honing head need to be connected to the honing head using a guide rod with a universal adjustment head, so that the honing head can achieve rotational motion while reciprocating in a straight line.

[0003] In order to suppress the swing of the universal honing head and prevent it from hitting the workpiece when it is placed in the hole of the workpiece to be honed, the honing equipment in the prior art is usually provided with a guide mechanism. In order to use the same honing equipment to process holes of different diameters, the honing equipment is usually equipped with honing heads of different sizes and specifications. Therefore, when the honing equipment replaces the honing head to process holes of different diameters, it is also necessary to replace the guide mechanisms of different sizes and specifications to limit the swing of the universal honing head, resulting in a large number of guide mechanisms equipped on the honing equipment, bloated equipment, and not conducive to improving processing efficiency. Some guide mechanisms in the prior art have improved the above problems through adjustable calibers, but the stability of their calibers is poor, and the caliber is easily changed under the action of the radial force generated by the universal honing head and the guide rod connected to it, affecting the honing effect.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0005] In order to solve the problem of poor stability of the guide mechanism in the prior art, the utility model provides a guide device. The guide device of the utility model comprises: a driving disk, the driving disk comprises a first locking portion; a fixed disk, the fixed disk is rotatably connected to the driving disk and comprises a second locking portion matched with the first locking portion; and a diameter-changing mechanism, the diameter-changing mechanism encloses a guide hole, when the driving disk rotates forward, the diameter-changing mechanism is driven to expand the guide hole, and when the driving disk rotates reversely, the diameter-changing mechanism is driven to reduce the guide hole, and the first locking portion and the second locking portion are used to limit the rotation of the driving disk so that the diameter of the guide hole remains unchanged.

[0006] The utility model provides a drive disk and a fixed disk so that an operator can adjust the diameter of the guide hole without frequently replacing the guide mechanism that meets the current honing head size, so that the honing equipment using the guide device of the utility model can meet the requirements of miniaturization, and when the honing head is replaced, the guide hole can be enlarged or reduced by rotating the drive disk, so as to limit the movement of the guide rod of the honing equipment. Through the provision of the first locking part and the second locking part, after the diameter of the guide hole surrounded by the diameter-changing mechanism changes, the first locking part and the second locking part limit the rotation of the drive disk to keep the diameter unchanged, so as to prevent the diameter-changing mechanism from being subjected to the force of the guide rod during the honing process, thereby causing the guide hole to expand.

[0007] In a preferred technical solution of the above-mentioned guide device, the driving plate includes a first circumferential wall, the fixed plate includes a second circumferential wall, the second circumferential wall is accommodated inside the first circumferential wall, and the center lines of the first circumferential wall and the second circumferential wall coincide with each other. Through the above-mentioned configuration, the driving plate can rotate around the center line to drive the guide hole surrounded by the diameter-changing mechanism to change its aperture size.

[0008] In the preferred technical solution of the above-mentioned guide device, the first locking portion includes a threaded hole formed on the first circumferential wall and a fastening screw matched with the threaded hole, and the fastening screw can abut against the second circumferential wall when being tightened. Through the above-mentioned arrangement, when the driving disk rotates around the center line by a predetermined angle so that the aperture meets the current honing head passing requirement, the fastening screw can be tightened so that the fastening screw abuts against the second circumferential wall and can limit the driving disk from continuing to rotate by friction or other means.

[0009] In the preferred technical solution of the above-mentioned guide device, the second locking portion is configured as a locking groove formed on the outer wall surface of the second circumferential wall, and the locking groove is used to accommodate the fastening screw. Through the provision of the locking groove, the effect of the fastening screw locking the driving disk is better.

[0010] In the preferred technical solution of the above-mentioned guide device, the locking grooves are arranged at equal intervals along the circumference on the second circumferential wall. Through the above-mentioned arrangement, when the fastening screw moves from one locking groove to another locking groove, the rotation angle of the driving disk is easy to obtain, and then the diameter change of the guide hole is calculated, which helps the operator to accurately change the diameter.

[0011] In the preferred technical solution of the above-mentioned guide device, the diameter-changing mechanism includes a plurality of sliders, each of which includes a guide surface, and the guide surfaces together form a guide hole. Through the above-mentioned arrangement, the structure of the diameter-changing mechanism is relatively simple, and replacing multiple sets of guide mechanisms in the prior art with the guide device of the utility model will not increase too much extra cost.

Through the above-mentioned arrangement, when the driving disk rotates by a predetermined angle, each first sliding part moves a first predetermined displacement in the first slide groove, and each second sliding part moves a second predetermined displacement in the second slide groove, so that the guide hole surrounded by the slider is enlarged or reduced.

[0013] In the preferred technical solution of the above-mentioned guide device, the driving disk is provided with a limiting hole, and the fixed disk is provided with a limiting member, and the limiting member extends from the fixed disk into the limiting hole; the limiting hole has a first end and a second end opposite to each other, and when the aperture is expanded to the maximum aperture, the limiting member is located at the first end, and when the aperture is reduced to the minimum aperture, the limiting member is located at the second end. Through the above-mentioned arrangement, the limiting hole and the limiting member cooperate to make the guide hole have a maximum aperture and a minimum aperture, so that the driving torque of the guide device is kept in an appropriate range, so that the operator can rotate the driving disk.

[0014] In order to solve the problem of poor stability of the guide mechanism on the honing equipment in the prior art, the utility model also provides a honing equipment. The honing equipment of the utility model includes the guide device in the above preferred technical solution. Through the setting of the guide device, the honing equipment can meet the requirements of miniaturization, and after replacing the honing head of different sizes, the guide hole can be quickly adjusted to the aperture matching the current honing head.

[0015] In the preferred technical solution of the above honing equipment, the honing equipment includes a honing head and a guide rod for driving the honing head, at least a portion of the guide rod is accommodated in the guide hole.
