Problems solved by technology

Since the diamond roller overhangs the outer side of the bearing, the bearings on both sides bear uneven alternating force during the rotation process, and the life of the bearing is short
In addition, due to the cantilever output shaft structure, the diamond roller has poor rigidity when dressing the grinding wheel, which affects the grinding performance of the machine tool

Embodiment Construction

[0009] See figure 2 , the improved diamond roller dresser of the present invention includes a housing fixing device and a dressing rotary device. The dressing rotary device includes a main shaft 4, and the main shaft 4 passes through two gear bearings 2-1, 2-2, and bearing seats 7-1, 7-2, Rotationally installed on the housing fixing device, one end of the main shaft 4 is connected with the pulley 1, the housing fixing device includes a support 6, a housing 8, the main shaft 4 is fitted into the roller sleeve 5 with an interference fit, and the outer diameter of the roller sleeve 5 is larger than the bearing Outer diameter of seat 7-1,7-2, roller cover 5 is positioned between two gear bearings 2-1,2-2, diamond roller 3 is installed on the roller cover 5. The housing 8 covers the main shaft 4 and is matedly connected with the support 6 .

[0010] The main shaft 4 is rotated through the bearings 2-1, 2-2 at both ends of the roller sleeve 5, and the bearing housing 7-1, 7-2. Aft...

Abstract

The invention provides an improved diamond idler wheel trimmer which comprises a shell fixing device and a trimming rotary device, wherein the trimming rotary device comprises a main shaft, the main shaft is rotatably arranged on the shell fixing device through two gears of bearings and a bearing block, and one end of the main shaft is connected with a belt wheel. The improved diamond idler wheel trimmer is characterized in that the shell fixing device comprises a support and a shell, wherein the main shaft is embedded in an idler wheel bushing in an interference fit manner, the outer diameter of the idler wheel bushing is more than that of the bearing block, the idler wheel bushing is positioned between the two gears of bearings, and a diamond idler wheel is arranged on the idler wheel bushing. Because two ends of the diamond idler wheel are supported by adopting the two gears of bearings, the bearings at two sides have uniform stress during the rotation, the service lives of the bearings are effectively prolonged, the rigidity during trimming a sand wheel is increased, and the sand wheel trimming quality is improved, thus the grinding property of a machine tool is ensured.

Description

technical field [0001] The invention relates to the technical field of grinding machine components, in particular to an improved diamond roller dresser. Background technique [0002] Existing diamond roller dresser structure see figure 1 , the pulley 1 drives the main shaft 2 to rotate through the flat key, so that the diamond roller 4 mounted on the shaft end on the right side of the main shaft 2 rotates the dressing wheel, and the bearing 3 is contained in the integral housing 5 . Since the diamond roller is suspended from the outside of the bearing, the bearings on both sides bear uneven alternating force during the rotation process, and the service life of the bearing is short. In addition, due to the cantilever output shaft structure, the diamond roller has poor rigidity when dressing the grinding wheel, which affects the grinding performance of the machine tool. Contents of the invention [0003] In view of the above problems, the present invention provides an impr...
