Abstract
The invention discloses a spiral moving type steel ball surface unfolding mechanism. Steel balls are put into a ball carrying device; the steel balls slide down along a hose; a hydraulic cylinder pushes the unfolding device to move towards the position of the ball carrying device at the right side; when a first shaft hole formed in the left side of the unfolding device is aligned with a hose opening, a stop hydraulic cylinder is opened, so that the steel balls fall into the unfolding device; the stop hydraulic cylinder is closed, and the unfolding device leftwards drives the steel balls to a position under a camera; a motor drives an unfolding roller to rotate; meanwhile, the unfolding roller and the motor leftwards move; the camera detects the steel balls in the detection region; after the detection is completed, the hydraulic cylinder leftwards moves the unfolding device; a separation device separates high-quality steel balls and defect steel balls according to results obtained through the analysis by a detection analysis device. The spiral moving type steel ball surface unfolding mechanism has the advantages that the detection conditions of each steel ball in the ball hole are identical; the steel ball surfaces are completely unfolded by using a spiral moving mode formed by overlapping the rotating movement and the linear movement of the unfolding roller, so that the goal of full surface detection of the steel balls is achieved.
Description
Technical field
The present invention relates to a kind of helical motion formula steel ball surface development mechanism, specifically a kind of efficient steel ball launches the method for detection.
Background technology
Along with the development in epoch, the automatization level of all trades and professions constantly improves, and the requirement meanwhile for plant equipment is also constantly improving.Bearing is as one of parts topmost in plant equipment, and the quality of its performance will affect equipment properties in the course of the work greatly.Bearing of a great variety, has double-row angular contact bal bearing, self-aligning ball bearing, taper roll bearing, thrust ball bearing, needle bearing etc., is also different according to the difference of working condition for selecting of bearing.The core parts that bearing can be made to complete its corresponding mission are its rolling bodys.According to the difference of the factors such as load-bearing capacity, support stiffness, permission angular displacement, limit speed, the shape of rolling body can be processed into different geometric shapes and meet required condition of work.The shape of rolling body has a variety of as ball, cylinder, circular cone, needle roller etc.Rolling body is as the core parts of bearing, and its surface accuracy will directly have influence on bearing performance operationally.
In the bearing roller of various shape, spherical surface detects difficulty the most, and therefore spherical surface detects and has been a great concern.China's detection mode is the earliest that workman's naked eyes detect, and is placed on monitor station, the surface of steel ball is amplified 100 times, and manually steel ball is carried out upset by workman and carry out full Surface testing by steel ball.The most original this detection method is very large to naked eyes damage, and the work age of workman is subject to larger restriction on average at about 40 years old.In testing process, Surface testing is subject to workman's mood, the impact of the factors such as self-condition, in testing process, steel ball overturns by mode manually, the method is difficult to ensure that the angle of each upset is identical, the detection of steel ball is so also made to be greatly affected, part surface can be caused to be occurred by the undetected situation of repeated detection or surface, thus make the validity of surface detection of steel ball receive impact.
Chinese patent (notification number CN102879371B) discloses a kind of method detecting contact steel ball development mechanism expansion effect, this device be steel ball is placed on scribble fluorescent powder expansion dish on do launch motion, make steel ball surface be coated with the mode spreading fluorescent powder whether to be detected completely to detect steel ball surface, carry out the amendment of detection scheme according to the effect detected.When steel ball rolls in the expansion panel surface scribbling fluorescent powder, have the generation of steel ball surface fluorescent powder obscission, the part that makes to come off is detected and is mistaken as and is not detected; In order to steel ball can be made to be assembled in bearing after steel ball has been detected, must be got rid of by the fluorescent powder that steel ball surface scribbles before assembly, this procedure has considerably increased the time of bearing assemble, reduces the efficiency of Production of bearing.
Chinese patent (publication number CN102658266A) discloses a kind of steel ball sorting equipment based on machine vision and method, its main principle of work is to being with in porose expansion dish by steel ball drop, steel ball is brought on frictional disk and detects by expansion dish, is separated by defect steel ball finally by ball mouth with high-quality steel ball.Certain uncertain factor is also there is in this detection method in the process launched.At the same N number of steel ball circumferentially carrying out detecting, because the hole heart that launches dribbling hole residing for steel ball of adding different from the position at frictional disk center in the centre of sphere horizontal direction of each steel ball causes the speed of the steel ball of diverse location in the process detected in testing process different to the different meeting of horizontal level of expansion dish core in the process launched.Having certain probability to make, the steel ball in centre position launches completely and expansion that the steel ball of both sides does not also launch to cause completely is insufficient, or when the steel ball of both sides launches complete, the steel ball in centre position has launched repeatedly to cause detection rates to reduce.
Chinese patent (publication number CN203117113U) discloses surface detection of steel ball instrument, this device detects steel ball surface, by a box, microscope is arranged on upper and lower and places a horizontal cylinder, 4 check-out consoles with the hollow out of different-diameter are placed above cylinder, steel ball is placed on above hole, right cylinder is rolled thus reaches the object detecting steel ball surface.Detect under needing steel ball to be brought into detect aperture when detecting, taken out after detection, this kind of method greatly reduces the speed of piano plate again, and large batch of piano plate will require a great deal of time, and greatly reduces the efficiency of detection; Right cylinder, in rotation process, can not solve the angle that steel ball rotates thus the situation that generating portion surface has been detected repeatedly or part surface is undetected; Size due to the hole on plate is different, and when carrying out mass detection same diameter steel ball surface, the detection rates of this device also will reduce greatly.
Chinese patent (notification number CN204514910U) discloses the expanding wheel device that steel ball surface defect detects, and its major function is placed on expanding wheel by steel ball, and under the drive of motor, steel ball does and launches motion.This kind of detection method can only detect a steel ball at every turn and detection speed is higher, all has a certain impact to the surface of expanding wheel and steel ball; Detect the diameter of steel ball single, the expanding wheel that the steel ball of different-diameter is corresponding different, carry out different-diameter steel ball when launching, need to change the model of expanding wheel, reduce work efficiency; Because expanding wheel is that therefore non-symmetrical structure is processed very difficult thus cause the cost of manufacture of expanding wheel greatly to promote.
Summary of the invention
In the present invention, the expansion situation of steel ball to be checked in development mechanism is substantially identical, and camera can detect fast with detection analytical equipment and analyze high-quality steel ball and defect steel ball, substantially reduces detection time, improves the detection efficiency of steel ball.
The present invention solves the technical scheme that its technical matters takes: a kind of helical motion formula steel ball surface development mechanism, and its step is as follows:
1, steel ball is put in year ball device;
