Detailed Implementation

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1 The present invention is an automated inspection device for bearing raceway grooves, comprising: a large plate 1, a side plate 2 mounted on the large plate, a controller 3, a product feeding and positioning mechanism 4 connected to the controller, an inspection platform 5, a raceway groove inspection mechanism 6 mounted on the inspection platform, and a product sorting and discharge mechanism 7. The controller is equipped with an operation panel for easy input of operation commands. The product feeding and positioning mechanism pushes the product to be inspected into the inspection station and positions and clamps the product to be inspected so that it is close to the side plate. The raceway groove inspection mechanism continuously inspects the raceway groove diameter and position online. The product sorting and discharge mechanism sorts and transports the good and defective products detected by the raceway groove inspection mechanism to the corresponding slides for discharge.

[0018] Please see Figure 2-3 The product feeding and positioning mechanism 4 includes two sets of inlet baffles 401, a pusher cylinder 402, an inlet tray 403, an outlet tray 404, and a product positioning component to be inspected disposed between the inlet tray and the outlet tray. A pusher rod 405 is provided on the output end of the pusher cylinder to push the product to be inspected on the inlet tray into the inspection station. During operation, the product 8 enters the inspection station along the inlet baffle. The pusher cylinder drives the pusher rod forward to push the product along the inlet tray to the inspection station. At the same time, the product that was originally in the inspection station (which has been inspected) is pushed out of the inspection station along the outlet tray. The pusher cylinder drives the pusher rod backward. The next product enters the inspection station along the inlet baffle under the action of gravity, completing the product feeding cycle.

[0019] Specifically, the product positioning assembly includes a clamping cylinder 406 mounted on the side plate, two sets of clamping rollers 407 mounted on the clamping cylinder, two sets of positioning rollers 408 cooperating with the clamping rollers, a drive wheel 409 driving the positioning rollers to rotate, a synchronous belt 410 positioned between the positioning rollers and the drive wheel, and a clamping assembly that presses the product to be tested against the side plate. After the product enters the testing station, the clamping rollers, pushed by the clamping cylinder, press the product against the positioning rollers. The drive wheel drives the positioning rollers to rotate via the synchronous belt. Under the action of the clamping rollers, the product begins to rotate. The drive wheel is driven by a servo motor, and parameters such as rotation speed, rotation direction, acceleration, and rotation time can be set according to requirements to meet testing needs.

[0020] Specifically, the holding assembly includes two sets of pressure levers 411. One end of each pressure lever is connected to the side plate via a spring element 412, and the other end is equipped with a carbide steel ball 413 for pressing the front of the product to be inspected. Two sets of carbide round bars 414 are arranged parallel to each other on the side plate, contacting the back of the product to be inspected. After the product enters the inspection station, the pressure roller presses the product onto the positioning roller. Simultaneously, the two carbide steel balls, under the action of the pressure levers and the spring element (usually a spring), press the product onto the side plate. Two carbide round bars are installed on the side plate, and after installation, the carbide round bars are slightly higher than the side plate by about 0.5mm. The product is pressed onto the carbide rod by the carbide steel ball under the action of the pressure lever and spring. The drive wheel drives the positioning roller to rotate through the synchronous belt. The product is pressed and positioned by the carbide steel ball, carbide rod and positioning roller and begins to rotate. The carbide steel ball and carbide rod are made of carbide, which reduces wear and improves positioning accuracy. At the same time, the arc surface of the carbide steel ball and carbide rod contacts the product, which reduces friction and ensures that the material surface will not be scratched.

[0021] Specifically, a circular groove is provided on the outer circumference of the positioning roller, and an O-ring 415 is provided in the groove to increase the friction between the product and the positioning roller, ensuring that the product can be driven to rotate by the positioning roller.

[0022] Please see Figure 4-6 The testing platform includes a platform base 51, a platform cylinder 52 mounted on the platform base, a testing drive cylinder 53 mounted on the platform cylinder, a testing platform base plate 54 mounted on the testing drive cylinder, two sets of longitudinal linear guides 55 mounted on the testing platform base plate, and a first mounting platform 56 and a second mounting platform 57 respectively slidably connected to the two sets of longitudinal linear guides. The raceway groove testing mechanism 6 includes a raceway groove position testing mechanism 61 mounted on the first mounting platform and a raceway groove diameter testing mechanism 62 mounted on the second mounting platform. The testing drive cylinder is a sliding cylinder to ensure the position repeatability accuracy of the cylinder during operation. The raceway groove inspection mechanism uses a detection drive cylinder to move the inspection mechanism into the inspection position and exit the inspection position when the product is transferred. The detection drive cylinder is mounted on a platform cylinder, which is also a sliding cylinder to ensure the repeatability accuracy of the position when the cylinder moves. The platform cylinder is used for equipment adjustment. When the equipment is adjusted, the platform cylinder moves backward, driving the entire raceway groove inspection mechanism to exit. This ensures that there is enough space for debugging the entire product inspection position during equipment adjustment, reducing the need to disassemble and assemble parts due to space constraints, and enabling quick and easy adjustment. To improve the inspection accuracy, a set of raceway groove inspection mechanisms can be set on each side of the product to be inspected.

[0023] Specifically, the raceway groove position detection mechanism 61 includes a first transverse linear guide rail 610 mounted on a first mounting platform, a first support platform 611 mounted on the first transverse linear guide rail, two sets of first mounting brackets 612 mounted on the first support platform, an "L"-shaped spring steel sheet 613 positioned between the two sets of first mounting brackets, a first detection terminal block 614 positioned at the front end of the "L"-shaped spring steel sheet, and a first raceway detection terminal 615 positioned at the front end of the first detection terminal block and in contact with the raceway groove of the product to be tested. The first raceway detection terminal has a double-arc structure, allowing for better contact with the product's raceway groove to ensure detection accuracy. A raceway position sensor 616 is mounted on one side of the first support platform, and a first actuating cylinder 617 is mounted on the other side. The output end of the first actuating cylinder is connected to a first push plate 618 on one side of the "L"-shaped spring steel sheet. A limit screw 619 is also mounted on one side of the first actuating cylinder to limit the pushing stroke of the first cylinder, positioning the product to be tested within the detection range. After the position is measured, the first actuating cylinder pushes the first push plate, which in turn causes the "L"-shaped spring steel sheet to deform, allowing the first detection terminal platform to smoothly move the first raceway detection terminal into the detection position. Then, the first actuating cylinder retracts, and the first raceway detection terminal, under the elastic force of the "L"-shaped spring steel sheet and the retraction action of the first actuating cylinder, comes into contact with the raceway groove of the product being tested. The raceway groove position sensor sends a signal to start the detection. It should be noted that the radial movement of the first raceway detection terminal on the product being tested is achieved by the deformation of the "L"-shaped spring steel sheet under the action of the first actuating cylinder. When the first actuating cylinder pushes the "L"-shaped spring steel sheet, the first support platform and the first transverse linear guide rail are locked and do not move. After the detection is completed, the first actuating cylinder actuates, and the detection drive cylinder drives the entire raceway groove position detection mechanism out of the detection position. The raceway groove position sensor automatically detects the raceway groove position signal and compares it with the set value to detect the raceway groove position of the product. It automatically calculates the maximum and minimum difference of the product's rotation and calculates the parallelism of the product's raceway groove.

[0024] Specifically, the raceway groove diameter detection mechanism 62 includes a second transverse linear guide rail 621 mounted on a second mounting platform, a second support platform 622 mounted on the second transverse linear guide rail, two sets of second mounting brackets 623 mounted on the second support platform, a second spring steel sheet 624 mounted between the two sets of second mounting brackets, a second detection terminal block 625 mounted at the front end of the second spring steel sheet, and a second raceway detection terminal 626 mounted at the front end of the second detection terminal block that contacts the raceway groove of the product to be tested. A raceway groove diameter sensor 627 is connected to the second spring steel sheet. A second actuating cylinder 628 is mounted on one side of the second support platform. The output end of the second actuating cylinder is connected to a second push plate 629 on one side of the second spring steel sheet. The raceway groove diameter sensor automatically detects the raceway diameter signal and compares it with a set value to detect the raceway diameter of the product. It automatically calculates the maximum and minimum difference between the product's rotations and calculates the roundness of the raceway groove diameter of the product. The working principle of other components of the raceway groove diameter detection mechanism is basically the same as that of the raceway groove position detection mechanism, and will not be described in detail here.

[0025] Please see Figure 7 The product feeding and positioning mechanism includes a fixed baffle plate 71 mounted on the side plate, an outlet sorting chute 72 mounted below the fixed baffle plate, a defective product outlet chute 73, a good product outlet chute 74, a pusher cylinder 75 mounted below the outlet sorting chute, a baffle cylinder 76 mounted between the outlet sorting chute and the defective product outlet chute, and a movable baffle plate 77 mounted on the output end of the baffle cylinder. After inspection, the finished product is pushed into the outlet sorting chute. When the inspected product is qualified, the baffle cylinder does not move, the movable baffle plate closes, and the pusher cylinder pushes the qualified product upwards. The qualified product is discharged through the qualified product outlet chute. When the inspected product is unqualified, the baffle cylinder moves, the movable baffle plate opens, and the defective product is discharged through the defective product outlet chute. All material discharge from the outlet sorting mechanism is achieved by rolling, preventing material from colliding with the equipment and causing cosmetic damage.
