Examples

Referring to fig. 1 to 3, the utility model discloses a high accuracy aversion bistrique mechanism, including bistrique support 30, rotary drive source 31, swivel sleeve 33, emery wheel 34, uide bushing 35, end cover 38 and guide rail (not shown in the figure).

The above-described rotation drive source 31 and the end cap 38 are provided on the grinding stone holder 30.

the end cap 38 has two oppositely disposed. A gland 36 is provided on each end cap 38. The gland 36 is located between two end caps 38. The gland 36 is capable of sealing the interior space from contaminants.

The guide sleeve 35 is a cylindrical housing. The two ends of the guide sleeve 35 are concentrically arranged on two sealing sleeves 36 respectively. The guide sleeve 35 is sleeved on the guide rail. The guide sleeve 35 can slide linearly along the guide rail to achieve the same high precision displacement, keeping the distance between the grinding wheel and the needle constant.

Specifically, the guide sleeve 35 is provided therein with an encircling portion 350, a collecting tank 351, a conveying tank 352, and a storage tank 353.

the two surrounding portions 350 are respectively located on the inner walls of the two ends of the guiding sleeve 35. The inner diameter of the embracing portion 350 coincides with the outer diameter of the guide rail. The surrounding portion 350 is tightly attached to the guide rail. The two surrounding parts 350 at the two ends can provide more balanced supporting force for the guide sleeve 35 so as to ensure the displacement precision, and cannot form larger contact area with the guide rail to reduce the abrasion speed.

The two collecting grooves 351 are respectively opened inside the surrounding portions 350 at both ends of the guide sleeve 35. The collection groove 351 is capable of collecting the lubricant smeared on the guide rail.

The conveying grooves 352 are two, and are respectively opened on different surrounding portions 350, and are located between the two collecting grooves 351. The feed channel 352 is helical. One end of the conveying tank 352 communicates with the collecting tank 351. The conveying groove 352 can convey the lubricant collected by the collecting groove 351 to the inside.

The storage tank 353 is provided in the middle of the guide sleeve 35. The inner diameter of the reservoir 353 is larger than the outer diameter of the guide rail. The storage tanks 353 are respectively communicated with the other ends of the two transfer tanks 352. The storage tank 353 can store the lubricant supplied from the supply tank 352 to provide a permanent lubrication between the guide rail and the guide sleeve 35, thereby ensuring the accuracy of the displacement and reducing the frequency of maintenance.

The guide sleeve 35 is rotatably sleeved with a positioning sleeve 37. The positioning sleeve 37 has two, which are respectively located at both ends of the guide sleeve 35. The positioning sleeve 37 can connect the guide sleeve 35 and the rotary sleeve 33 and make them rotate freely relative to each other. The positioning sleeve 37 can be a bearing, and has simple structure and long service life.

The rotary sleeve 33 is provided on the outer peripheral surface of the positioning sleeve 37. A rotation drive belt 32 is provided between the rotation sleeve 33 and the rotation drive source 31. The rotary drive source 31 can rotationally drive the rotary sleeve 33. The grinding wheel 34 is sleeved on the rotating sleeve 33. When the rotating sleeve 33 rotates, the grinding wheel 34 can be driven to rotate, so that the needle is ground.

Specifically, the rotating sleeve 33 includes a combination sleeve 330 and a pressing sleeve 333.

The combination set 330 is disposed on one of the position sleeves 37. The outer circumferential surfaces of both ends of the combination cover 330 are provided with a rotation driving belt groove 331 and a grinding wheel groove 332, respectively. The rotary drive belt 32 is disposed within the rotary drive belt slot 331. The wheel groove 332 includes a wheel-securing torus and a wheel ring strip. The grinding wheel ring strip is arranged on one side of the grinding wheel fixing ring surface. The other side of the wheel retaining annulus extends to the end face of the combination sleeve 330. The grinding wheel ring can limit the position of the grinding wheel 34. The wheel retaining annulus facilitates removal of the grinding wheel 34.

The pressing sleeve 333 is provided on the other positioning sleeve 37 and concentrically fitted to the end of the combined sleeve 330 on the side of the grinding wheel holding ring surface. The end of the pressing sleeve 333 is provided with a grinding wheel ring strip. The grinding wheel ring strip can be sleeved on the grinding wheel fixing ring surface. The grinding wheel ring strip is provided with a gasket 334. The gasket 334 can be suitable for grinding wheels 34 of different specifications, and can also avoid the influence of thickness errors of the grinding wheels 34 on use. The pressing sleeve 333 can firmly press the grinding wheel 34 between the two grinding wheel ring strips, thereby improving the rotation precision.

As a further improvement of the present invention, the rotary drive belt 32 is a v belt. The groove width of the rotary driving groove is gradually increased from the inner ring to the outer ring. The V-belt is arranged in the rotary driving belt groove. The matching is more close along with the increase of the pulling force, and the transmission precision is high.
