The following disclosure provides many different embodiments, or examples, for implementing different aspects of the utility model.

As shown with reference to figures 1 to 2,

the utility model discloses a polishing tool applied to a workpiece with a continuous inner channel, which comprises:

the base 1 is a bearing base applied to a polishing tool with a continuous inner channel workpiece, and a first hole penetrating the base 1 upwards is formed in the base 1. It is emphasized herein that "upwardly" includes both vertically upwardly (i.e., longitudinally) and obliquely upwardly. Preferably, the base 1 is provided in a circular shape, and the first hole is provided at the center of the base 1.

The base column 2 is arranged on the base platform 1, the periphery of the base column 2 is used for sleeving the workpiece 4, and the base column 2 is provided with a second hole which comprises a main hole 21 and a branch hole 22 communicated with the main hole 21. The main hole 21 is disposed upward inside the base pillar 2, and the main hole 21 is preferably a blind hole, in this embodiment, the base pillar 2 is cylindrical, and the main hole 21 is disposed longitudinally and coincides with the axis of the base pillar 2. The branch hole 22 is arranged on the side surface of the foundation column 2, and one end of the branch hole 22 is ensured to be positioned on the side surface of the foundation column 2. Preferably, the branch hole 22 is provided in plurality.

In the present embodiment, the base post 2 is integrally formed with the base 1, and the first hole and the main hole 21 are longitudinally collinear and communicate. The branch holes 22 are horizontally arranged, the number of the branch holes is four, the included angle between every two adjacent branch holes 22 is a right angle, and the included angle between each branch hole 22 and the main hole 21 is also a right angle. In order to ensure that the grinding effect can act on the whole path of the inner channel, it is preferable that the branch hole 22 is flush with the initial end of the inner channel, that is, the lower end of the inner channel is the initial end of the abrasive flowing from bottom to top in the present embodiment.

And a gland 3, the gland 3 being disposed at the upper end of the base column 2 and detachably connected to the base column 2 by connecting the gland 3 to the base column 2 via a screw 32. The gland 3 is used for clamping the workpiece 4 between the gland 3 and the base platform 1, so that the workpiece 4 can be fixed on the base platform 1 and can be tightly connected between the workpiece 4 and the base platform 1, and preferably, a rubber gasket can be additionally arranged between the workpiece 4 and the base platform 1, so that the sealing performance is ensured. A third bore 31 is also provided in the gland 3, which third bore 31 extends upwardly through the gland 3.

A workpiece 4, the workpiece 4 being provided with a continuous inner channel in the inner wall, as is common with nuts.

The aforementioned workpiece 4 also typically has a shoulder 41, the shoulder 41 being provided at a bottom end of the workpiece 4, and in this embodiment, the workpiece 4 is integrally formed with the shoulder 41, and the shoulder 41 is fixed to the abutment 1 by a fastener 42. The form of the fastening member 42 is various, and in the present embodiment, only a screw is used as one expression, and other mechanisms, members, etc. that can fix the shoulder 41 to the abutment 1 should be regarded as the fastening member 42.

The abrasive material is made of a semifluid material and has certain viscosity, so that the abrasive material can not only grind the surface of the workpiece 4, but also permeate into the fine pores of the workpiece 4 to finish finer polishing. In addition, the viscosity of the abrasive is such that the abrasive does not damage the workpiece 4 during the grinding and polishing process, resulting in the rejection of the workpiece 4.

In order to ensure that the tool can be better connected with a machine for providing high-pressure particles to convey abrasive materials, the pipe joints 5 are arranged in the first hole and the third hole 31, so that the connection is convenient.

When using this frock, the entry that abrasive material got into this frock is regarded as to first hole, and this frock is flowed out by third hole 31 behind main hole 21, branch hole 22, the interior channel in proper order to the abrasive material, and the abrasive material flows between 2 sides of foundation columns and interior channel, has played the polishing effect to interior channel. Since the abrasive is accumulated above the base pillar 2 after flowing through the inner channel, a certain gap is required to be left between the upper end surface of the base pillar 2 and the end cover, so that the abrasive is conveniently collected above the base pillar 2 and flows out from the third hole 31.

In this embodiment, the abrasive material adopts from bottom to top mode to flow, can increase the effort of mutual extrusion between the abrasive material with the help of the gravity of abrasive material self, better to the inner channel carry out grinding and polishing.

In addition, the structure that the main hole 21 is communicated with the branch holes 22 can reduce the abrasion of the abrasive to each hole, particularly to the first hole and the main hole 21, can reduce the replacement frequency of the pipe joint 5 when the pipe joint 5 is matched, and because the main hole 21 and the branch holes 22 are arranged inside the foundation column 2, the main hole 21 and the branch holes 22 are not damaged even if being abraded, but the hole diameter is enlarged due to the abrasion, more abrasive can flow in, the pressure between the abrasive is larger, and the grinding and polishing effect is better.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the utility model, the scope of which is defined by the claims and their equivalents.
