Problems solved by technology

However, during the grinding process of the grinding wheel, due to the wear of the grinding wheel itself, the state of the working surface of the grinding wheel is constantly changing. With the prolongation of the grinding time of the grinding wheel, the cutting ability of the grinding wheel decreases, and various grinding defects continue to appear. The grinding process cannot continue, and the grinding wheel must be repaired at this time to restore the normal grinding state
Therefore, the quality of the grinding wheel dressing accuracy directly affects the later use effect and grinding effect of the grinding wheel, and the current grinding wheel dressing method is generally adjusted by the rough adjustment method of surface contact on the linear slide rail, resulting in low adjustment accuracy, resulting in The dressing effect of the grinding wheel is not good, which affects the grinding effect in the later stage, resulting in a high rework rate of the product and affecting the processing speed

Embodiment 1

[0027] Such as figure 1 , figure 2 , image 3 As shown, the grinding wheel dresser of the full-automatic bearing ring inner ring channel grinder machine provided in this embodiment includes a base 1-1, and a mounting seat 1-2 is provided on the base 1-1. Mounting seat 1-2 is provided with one side and is the fixed seat 1-3 of arc-shaped structure, is provided with diamond pen 1-4 on the upper end of fixed seat 1-3, is also provided with on fixed seat 1-3:

[0028] The countersunk bolt 1-5 that cooperates with the external adjustment knob is provided with a circle of positioning ring 1-6 on the outer periphery of the screw rod of the countersunk bolt 1-5;

[0029] Lever 1-9, described lever 1-9 is the lever 1-9 that can make the diamond pen 1-4 carry out horizontal movement after the fixed shaft 1-11 on the fixed seat 1-3 is rotated around, and the lever 1-9 is close to the emery wheel. One end of 9 is provided with rolling ball 1-10 and is installed in the positioning ring...

Embodiment 2

[0037] Such as Figure 4 As shown, the general structure of the grinding wheel dresser of the fully automatic bearing ring inner ring groove grinder machine provided in this embodiment is the same as that of Embodiment 1. The difference is that in order to realize two sets of line contacts composed of point contacts, In this way, the force is more uniform and the adjustment is smoother during sliding positioning: the slide rail 1-16-4 includes three sets of slideways 1-19 evenly arranged from top to bottom, and the upper and lower sets of slideways 1-19 19 is provided with one or more balls 1-20, and the two rows of balls 1-20 cooperate with the above-mentioned sliding block 1-16-5, and the above-mentioned sliding block 1-16-5 is provided with the upper and lower rows. Elastic fixing piece 1-16-5-1 is provided with elliptic spacer groove 1-22 at the position and center of each ball 1-20 installed, and both sides of described elliptic spacer groove 1-22 are provided with center...

Embodiment 3

[0039] Such as Figure 5 As shown, the general structure of the grinding wheel dresser of the fully automatic bearing ring inner ring groove grinding superintegrated machine provided in this embodiment is the same as that of Embodiment 1, the difference is that in order not to affect the grinding of the grinding wheel, the The base 1-1 is provided with a third motor 1-7 that enables the fixed base 1-3 to move vertically towards the grinding wheel, and the output shaft of the third motor 1-7 is connected with the mounting base 1-2. The seat 1-1 is provided with a slide bar 1-8 that cooperates with the mounting seat 1-2 to slide. During work, the work of the third motor 1-7 drives the fixed seat 1-3 close to the emery wheel or away from the emery wheel, so it can be moved according to the emery wheel. The specific position adjusts the position of the fixing seat 1-3, thereby adjusting the position of the diamond pen 1-4 close to the grinding wheel, so as to be suitable for grind...

Abstract

The invention discloses a grinding wheel dresser for an inner ring channel grinding super all-in-one machine for a full-automatic bearing sleeve ring. The grinding wheel dresser comprises a fixed seat arranged on an installation seat of a base. The fixed seat is provided with a diamond pen, a countersunk bolt, a second motor, a first motor and a lever. A locating ring is arranged on the outer side periphery of a screw of the countersunk bolt. A rolling ball installed in the locating ring is arranged at one end of the lever. The other end of the lever is fixed to the diamond pen. The length from the lever to the rolling ball is larger than the connection length of the lever with a fixed shaft. The first motor is sleeved with a shaft sleeve. A curled edge of an inclined table surface structure is arranged on the periphery of the shaft sleeve. A bevel of the curled edge is arranged on the outer side and movably connected with a baffle below the fixed seat in an abutted mode. An elastic adjustment device is arranged in the position, opposite to the upper portion of the bevel of the curled edge, on the baffle, and when the shaft sleeve rotates, the fixed seat is made to conduct horizontal motion on the installation seat through the elastic adjustment device. A motor speed reducer is arranged on the second motor and connected with the fixed seat. Through the grinding wheel dresser, the adjustment precision can be improved, so that the grinding wheel dressing effect is higher, and the stress during adjustment is more uniform.

Description

technical field [0001] The invention relates to a grinding wheel dresser, in particular to a grinding wheel dresser of a full-automatic inner ring channel grinding machine for bearing rings. Background technique [0002] Grinding wheel, also known as bonded abrasive, is a bonded abrasive with a certain strength that consolidates ordinary abrasives into a certain shape (mostly round, with a through hole in the center) by a bond. Moreover, the grinding wheel is the one with the largest amount of consumption and the widest range of applications in abrasive tools. It rotates at high speed during use and is suitable for processing various metal and non-metal materials. However, during the grinding process of the grinding wheel, due to the wear of the grinding wheel itself, the state of the working surface of the grinding wheel is constantly changing. With the prolongation of the grinding time of the grinding wheel, the cutting ability of the grinding wheel decreases, and various ...
