Grinding machine

Abstract

A grinding machine for executing machine vision measurement is disclosed. The grinding machine includes a grinding unit, an installing panel, and a first driving unit driving vertical movement of grinding unit. The grinding unit and the installing panel are slidably connected to two linear rails, a connection device connected to the installing panel and the grinding unit, a camera unit and a light source unit fixed to the installing panel. The installing panel is located in front of the linear rails. The connection device includes a case, a pushing-rod, and a second driving unit. The second driving unit drives the motion of the pushing-rod relative to the case. The case is fixed to one of the grinding unit and the installing panel, and the pushing-rod is fixed to the other of the grinding unit and the installing panel.

         2 . The grinding machine as claimed in  claim 1 , wherein the grinding unit comprises a grinding wheel, a motor driving the grinding wheel to rotate, a spindle connected to the grinding wheel and the motor, an outer case surrounding the spindle, and an extending plate which integrally extends from the outer case to the two linear rails; the extending plate is located behind the grinding wheel, the spindle passes between the two linear rails along the front-to-back direction, and the extending plate and the installing panel both slidably connect the two linear rails by a plurality of sliders. 
     
     
         3 . The grinding machine as claimed in  claim 2 , wherein the installing panel comprises two side plates located on two sides of the extending plate and an upper plate is integrally connected to the two side plates; the two side plates are respectively connected to the camera unit and the light source unit, and the upper plate slidably connects the two linear rails by the two sliders. 
     
     
         4 . The grinding machine as claimed in  claim 3 , wherein the installing panel comprises a fixed plate connected to one of a bottom surface of the upper plate and a top surface of the lower plate, the case is fixed to the fixed plate, and the pushing-rod mechanism is fixed to the extending plate of the grinding unit. 
     
     
         5 . The grinding machine as claimed in  claim 4 , wherein the installing panel comprises two reinforcement plates located on the fixed plate and connected to the fixed plate, the reinforcement plate is connected to a front surface of the upper plate, the case is located on a front side of the installing panel and located between the two reinforcement plates, the pushing-rod mechanism is fixed to a front surface of the extending plate and does not extend forward beyond the grinding wheel, and the second driving unit is located behind the case and above the installing panel. 
     
     
         6 . The grinding machine as claimed in  claim 4 , wherein the case is located on a rear side of the installing panel, the pushing-rod mechanism is fixed to a rear surface of the extending plate, and the second driving unit is located in front of the case and above the installing panel. 
     
     
         7 . The grinding machine as claimed in  claim 6 , wherein the installing panel comprises two reinforcement plates located on the fixed plate and connected to the fixed plate, the two reinforcement plates are connected to a rear surface of the upper plate, and the case is located between the two reinforcement plates. 
     
     
         8 . The grinding machine as claimed in  claim 3 , wherein the installing panel further comprises a lower plate located under the extending plate, the lower plate is integrally connected to the two side plates, the lower plate connects to the two linear rails by the two sliders, a front surface of the upper plate and a front surface of the lower plate are coplanar with a front surface of the extending plate, and a distance between the upper plate and the lower plate is greater than a vertical height of the extending plate itself. 
     
     
         9 . The grinding machine as claimed in  claim 4 , wherein a front surface of the side plate is coplanar with a front surface of the extending plate, a first distance is between the fixed plate and one of the side plate, a second distance is between the fixed plate and the other side plate, and the first distance is equal to the second distance. 
     
     
         10 . The grinding machine as claimed in  claim 2 , wherein the extending plate protrudes upwards, downwards, leftwards, and rightwards respectively from the outer case, the plurality of sliders are fixed on the extending plate, and each of the two linear rails are connected to the plurality of sliders fixed on the extending plate.
