Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the simple device for identifying the irregular groove diameter for feeding of the bearing inner groove grinding machine comprises a fixed frame 1, a material channel 2, two measuring rods 3 and two measuring rod lifting adjusting devices 4;
the material channel 2 obliquely penetrates through the left side and the right side of the fixing frame 1, and the feeding end 5 of the material channel is higher than the discharging end 6 of the material channel; the two measuring rod lifting adjusting devices 4 are oppositely arranged on the upper side and the lower side of the fixed frame 1, and the two measuring rods 3 are oppositely arranged on the corresponding measuring rod lifting adjusting devices 4 and vertically extend to the two sides of the material channel 2 into the fixed frame 1; one ends of the two measuring rods 3, which are close to the material channel 2, are provided with spherical measuring heads 7, corresponding detecting holes are formed in the joint of the material channel 2 and the spherical measuring heads 7, and the channel diameter abnormity identification of the bearing inner ring 8 channel in the material channel 2 is realized through the spherical measuring heads 7 extending into the material channel 2.
In this embodiment, a first proximity switch 9 is disposed on the side wall of the discharging end 6 of the material channel 2, and a second proximity switch 10 is disposed on the side wall of the feeding end 5.
As shown in fig. 2 and 3, the curvature of the spherical probe 7 is the same as the channel curvature Ri of the bearing inner ring 8, and is made of a diamond material; the distance D between the bottoms of the two spherical measuring heads 7 is 0.03-0.06 mm larger than the groove diameter di of the bearing inner ring 8, and the central connecting line of the two spherical measuring heads 7 is superposed with the central line of the inner groove of the bearing.
As shown in FIGS. 4 and 5, the height B of the longitudinal section of the material channel 2 is 5-8 mm larger than the outer diameter d2 of the bearing inner ring 8, and the width C is 3-6 mm larger than the width B1 of the bearing inner ring 8.
In this embodiment, arc-shaped positioning protrusions are arranged at the top and the bottom of the inner wall of the material channel 2.
The specific embodiment of the invention is as follows:
(1) the device is arranged in a material channel after an automatic feeding machine and before a groove grinding process, when an inner ring with the groove diameter within a set range flows down from the automatic feeding machine and enters the simple device, two measuring heads extend into a groove of the inner ring, and the distance D between the two measuring heads is adjusted into a fixed distance (correspondingly adjusted by a measuring rod lifting adjusting device) according to the qualified groove diameter di and is 0.03-0.06 mm larger than the qualified groove diameter di, so that a ferrule with the groove diameter size of the inner ring being 0.06mm larger than the qualified groove diameter di can flow between the two measuring heads and enter a machine tool, and the machine tool carries out normal grinding;
(2) when the non-ditch inner ring flows down from the automatic feeding machine and enters the simple device, the size of the ditch diameter of the inner ring is far larger than the standard size di, and the size of the ditch diameter of the non-ditch is also far larger than the distance D between the two measuring heads, when the inner ring ditch passes through the two measuring heads, the inner ring ditch is clamped by the two measuring heads, other inner rings flowing down from the automatic feeding machine are accumulated in the material channel, the proximity switch II senses and sends a signal to the automatic feeding machine to stop feeding and give an alarm, and the collision phenomenon of the non-ditch inner ring is effectively prevented;
(3) when the groove diameter of the inner ring is special or the curvature of the groove is too small, the inner ring can be clamped by the two measuring heads, the inner ring cannot flow into a machine tool, and the principle analysis is the same as the step (2);
(4) when the machine tool breaks down and stops working, the inner ring flowing through the device can be accumulated in the material channel, and the proximity switch senses and sends a signal to the automatic feeding machine for stopping feeding and giving an alarm.
Therefore, after the simple device is additionally arranged on the groove grinding machine tool, the groove-free or groove-shaped abnormal inner ring can be effectively prevented from flowing into the machine tool, and in addition, through the installation of the two proximity switches, when the machine tool stops working or a special-shaped groove diameter ferrule is clamped by the two measuring heads, the automatic feeding machine can stop feeding, so that the inner ring is prevented from damaging the support and the grinding wheel, the shutdown time is reduced, the production efficiency is improved, and the processing cost is indirectly reduced.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
