[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model protection.

[0025] The utility model discloses a kind of honing tool structures, to solve the problems existing in prior art, facilitate operator to hold part and carry out honing processing, and reduce security risk.

[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, easy to understand, the utility model will be further described in detail below in conjunction with drawings and specific embodiments.

[0027] As Figs. 1-3 Indicated, the utility model provides a kind of honing tool structures: including clamping sleeve 1 and fixed rod 4;Wherein, clamping sleeve 1 is provided with the through hole 3 for the part to be processed to pass, and the through hole 3 is matched with the gap of the outer wall of the part to be processed;The outer circumferential surface of clamping sleeve 1 is provided with threaded hole 2, and threaded hole 2 is communicated with through hole 3;Fixed rod 4 is provided with external thread 5 at one end, and external thread 5 is connected with threaded hole 2, and after connection, the end of external thread 5 is fixed with the part to be processed;

[0028] By adopting the setting clamping sleeve 1, and setting threaded hole 2 on clamping sleeve 1 and matched with the gap of the part to be processed, the external thread 5 of fixed rod 4 is rotated into the threaded hole 2 of the clamping sleeve 1, and is fixed with the part to be processed, so that the operator can put the inner hole of the part to be processed on the honing head by hand holding fixed rod 4 to carry out honing processing, which is convenient to operate, and greatly reduces the security risk such as part falling off.

[0029] As an implementable example, the gap size between through hole 3 and the outer wall of the part to be processed is set to 0.005-0.01mm, which effectively improves the coaxiality of the inner hole of the part to be processed and through hole 3, thereby improving the machining precision.

[0030] As an example, knurling is provided on the outer wall of the clamping sleeve 1 and the fixed rod 4, which increases the friction when the operator operates, facilitates taking, prevents falling off, and improves the safety factor.

[0031] As an example, as shown in the figure, Fig. 2 the outer thread 5 is provided with an outer thread boss 6 near the end of the part to be machined, and the diameter of the outer thread boss 6 is smaller than the outer diameter of the outer thread 5. By setting the outer thread boss 6 with a smaller diameter, the operator can quickly position and insert the fixed rod 4 into the threaded hole 2, and at the same time, the outer thread boss 6 has no thread, which can reduce the time of rotating the fixed rod 4 into the fixed position, so as to quickly abut and fix the end of the fixed rod 4 with the part to be machined, and improve the use efficiency.

[0032] As an example, as shown in the figure, Fig. 2 the outer thread boss 6 is further provided with a conical head 7 near the end of the part to be machined, and the diameter of the conical head 7 near the end of the outer thread boss 6 is equal to the outer diameter of the outer thread boss 6, and the diameter of the other end of the conical head 7 is smaller than the outer diameter of the outer thread boss 6. By setting the conical head 7, when there is a hole on the outer wall of the part to be machined, the end of the conical head 7 with a smaller diameter can be inserted into the hole on the outer wall of the part to be machined for fixation and limiting, further increasing the stability of fixing the part to be machined, and the conical structure has high compatibility with the size of the hole on the outer wall of the part to be machined; At the same time, a cylindrical boss 8 can also be provided on the end of the conical head 7 near the part to be machined, and the diameter of the cylindrical boss 8 is the same as the diameter of the end of the conical head 7 near the cylindrical boss 8. The smaller diameter cylindrical boss 8 can be quickly inserted into the hole on the outer wall of the part to be machined for fixation, improving the machining efficiency.

[0033] As an example, the threaded hole 2 and the fixed rod 4 are both provided with two, and are one-to-one corresponding; the axes of the two threaded holes 2 are perpendicular to the axis of the through hole 3 and intersect at the same point, and the included angle between the axes of the two threaded holes 2 is 120°-180°, which is convenient for the operator to hold with both hands, greatly increasing the stability during honing.

[0034] As an example, as shown in the figure, Fig. 3 a gap 9 is provided on the outer wall of the clamping sleeve 1 and communicates with the through hole 3, so as to increase the contact area of the cooling medium with the part during honing, so that the part is quickly cooled, preventing high temperature from causing harm to the operator; wherein the gap 9 includes at least one pair, any pair of gaps 9 is collinear in the axial direction of the through hole 3, and both are U-shaped, and the openings are respectively located at both ends of the clamping sleeve 1, which not only increases the cooling area, but also facilitates the cooling liquid to enter the two gaps 9 from the same axis for cooling.

[0035] As an implementable example, the clamping sleeve 1 can be cylindrical and made of aluminum, which is soft and can effectively prevent damage to the parts.

[0036] The principle and implementation mode of the utility model are described by applying specific examples in the utility model, and the above embodiment is only used for helping to understand the core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
