Problems solved by technology

[0003] When the grinding wheel installed on the grinding wheel frame of the grinding machine is in the process of starting to speed balance, the grinding wheel will always produce vibrations of different amplitudes, which will virtually increase the compliance and wear of bearings and spindles. If the grinding wheel grinds the workpiece at this time grinding, the grinding wheel cannot obtain stable grinding, so it is easy to produce abnormal phenomena such as grinding vibration waves, workpiece scorching and cracking, and poor roughness of the processed surface, which increases the defective rate of the workpiece; in addition, the life of the machine parts (such as bearings) and the main shaft) are bound to be shortened, increasing the cost of updating or repairing
Therefore, every time the grinding wheel is started, it takes a long time to wait for the speed of the grinding wheel to balance. For novices and even veterans, it is impossible to accurately judge when the grinding wheel reaches the balance of speed, so they will wait for a while to ensure The grinding wheel reaches the speed balance. In this way to ensure that the grinding wheel reaches the speed balance, too long waiting time will be wasted and the processing efficiency of the workpiece will be reduced.

Embodiment 1

[0033] Embodiment one: a kind of grinding wheel balance detection device, such as figure 1 , figure 2 , image 3 As shown, it includes a frame 1, a main shaft 16 and a tailstock 17 respectively arranged at both ends of the length direction of the frame 1, a grinding wheel frame 2 slidingly connected to the frame 1 along the width direction of the frame 1, and a grinding wheel frame 2 connected to the grinding wheel frame through bearing rotation. The grinding wheel 3 of 2, the grinding wheel motor 4 that controls the rotation of the grinding wheel 3 through belt transmission (see Figure 4 ) and the servo motor 5 that controls the movement of the grinding wheel frame 2. The tailstock 17 is slidably connected to the frame 1 along the length direction of the frame 1. The tailstock 17 is fixed with a top 18 on the side facing the main shaft 16, and one end of the workpiece is clamped on the main shaft 16. Inside, the other end is fixed by the top 18, the lower end of the grind...

Embodiment 2

[0040] Embodiment two: a kind of grinding wheel balance detection device, such as Figure 7 , Figure 8 As shown, the difference from Embodiment 1 is that the balance detection device 6 is fixed on one side of the clamping piece 14 by bolts, and the cross section of the clamping piece 14 is I-shaped. A card slot 15 matched with the clamping piece 14 is directly opened, and the upper end of the card slot 15 is provided with an opening, and the clamping piece 14 is inserted into the card slot 15 from the upper end of the card slot 15, thereby fixing the balance detection device 6 on the grinding wheel frame 2 top; in order to prevent the clip 14 from vibrating in the up and down direction in the clip slot 15, a rubber plug 19 is clipped at the opening of the upper end of the clip slot 15, and the lower end of the rubber plug 19 abuts against the upper end of the clip 14, Thus, the clamping member 14 is firmly clamped in the clamping groove 15 .

Abstract

The invention discloses a balance detection device of a grinding wheel. The detection device comprises a rack, a grinding wheel rack slidably connected to the rack, the grinding wheel rotatably connected to the grinding wheel rack, a grinding wheel motor controlling the rotation of the grinding wheel and a servo motor controlling the movement of the grinding wheel rack. A balance detection apparatus is arranged on the grinding wheel rack. A control module is connected to the balance detection apparatus. The output end of the control module is connected with the input end of the servo motor. The output end of the control module is connected with a first indicator lamp. According to the invention, it can be quickly known that the rotation speed of the grinding wheel is balanced, so redundant waiting time is avoided; and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of grinding machines, more specifically, it relates to a grinding wheel balance detection device. Background technique [0002] Grinding wheel is the most important type of mold in grinding process. The grinding wheel is a porous body made by adding a binder to the abrasive, compacted, dried and roasted. When in use, it rotates at a high speed and can be used for grinding the outer circle, inner circle, plane and various types of metal or non-metallic workpieces. Coarse grinding, semi-finishing and fine grinding as well as grooving and parting off etc. During the manufacturing process of the grinding wheel, because the particles of the grinding wheel are not absolutely evenly distributed, some parts of the formed grinding wheel are light and some parts are heavy, resulting in an unbalanced problem of the formed grinding wheel. Therefore, when loading the grinding wheel into the grinding machine , the grind...
